Colliding stars reveal their gravitational wave secrets
Australian scientists have announced an “unparalleled” astrophysical discovery revealing that they have detected gravitational waves from the death spiral of two neutron stars.
Less than a month after three US professors were awarded the Nobel Prize in Physics for the 2015 discovery of gravitational waves, a team of Australian astrophysicists, including Swinburne researchers, have announced a new international discovery.
It is the first time a cosmic event has been observed and measured in both light and gravitational waves.
Swinburne hosts the $31.3 million Australian Research Council’s Centre of Excellence for Gravitational Wave Discovery (OzGrav) which was established last year to capitalise on the original discovery of gravitational waves.
Swinburne’s Professor Matthew Bailes, Director of OzGrav, says the new discovery has enabled scientists to pinpoint the origin of gravitational waves and to actually see “the colossal event” that accompanied the gravitational waves.
“This was the first time that any cosmic event was observed through both the light it emitted and the gravitational ripples it caused in the fabric of space and time,” Professor Bailes says.
“The subsequent avalanche of science was virtually unparalleled in modern astrophysics.”
OzGrav is a collaboration between six universities in Australia – Swinburne University of Technology, Australian National University, the University of Western Australia, Monash University, the University of Melbourne, and the University of Adelaide.

This is a common problem. It may be that the charger is dammaged. these Dell chargers have a micro thin communication cable in them that tell the charger to charge the battery. this micro thin cable can often break. Its use it to prevent the laptop battery from over charging, but if it breaks or becomed broken inside tha charger cable, then the laptop simply won't get the charge signal and the battery won't charge. If this is the case, then you will need to replace the charger with another Dell charger compatible with your laptop
The ambar lights are warning you the battery is becoming to dead, it means in a short time, if it has not happens now, the battery won't retain the charge anymore, it is time thinking in a replacement if you use your laptop without plug in the power outlet.
sounds like your charging circuit isn't working or the adapter isn't putting out enough power or amprage to fully charge the battery, or you battery went bad. if the charging circuit is bad then so is *********** board, time to burry the system and buy a new one
First thing I would try is to unplug the machine, remove the battery and clean the contacts on the battery and in the battery housing with a pencil eraser. Blow out the shavings and reinstall battery - the way it sounds is that there may be dirt or corrosion causing an interference between the computer and battery contacts - for charging and powering up.
Try this trick. Remove the battery from the laptop and make sure the ac adapter is not plugged in also. Hold the power button for 30 seconds. Place the battery back in and see if it powers on. If not let me know.
Try to turn off the computer and remove the battery from the bottom of the notebook. Turn on the computer with just the charger plugged in. If it doesnt turn on. you may have a bad power port.
If it has no power/charging issue since that happened except that the indicator light doesnt turn on when you plug in the charger, you may just need a bios update. Click here. That's the bios update for the inspiron 2200 from dell's website. You should have at least 30% charge on the battery and the ac adapter should be plugged in so you can run it. The computer will restart and will come back normally after this. I'd suggest that you backup your files before running this.

|BBC Micro Disc Drive Switcher|
Here at the Archive we come across a range of different disc sizes and formats. Not only that but we also receive a range of disc image types. Recently the Archive has invested in a GreaseWeazle, which can read protected DFS format floppy discs and save these as HFE images which preserve the protection.
To read HFE disc images and convert them to SSD images where possible, the Archive uses a GOTEK floppy drive emulator. This has been built into a spare, self-powered 5.25" floppy drive enclosure and is connected when needed.
Swapping disc drives in this way is a tedious process and could cause damage to the connectors on the BBC computers used.
The Archive mainly uses BBC Master computers complete with Retroclinic Datacentres to make images to preserve. The Datacentre is used to export the images as SSD/DSD files. The main archiving machine has dual 40/80T 5.25" floppy drives permanently attached. 5.25" is the de facto standard for educational software on the BBC range. 3.5" floppy discs are also encountered aimed at the BBC Master Compact range or the Archimedes range of computers, where they run under emulation.
A second BBC Master computer was set up with 3.5" and 5.25" floppies connected using a Watford Electronics Duck, a device which takes two single drives and combines them to make a single dual drive. This machine is used to make ADFS disc images from 3.5" floppy discs using OmniFlop on a Windows XP PC.
With the introduction of the GreaseWeazle device a GOTEK floppy drive emulator was needed to be permanently available and the secondary BBC Master computer was the target machine. What was needed was a switch which would swap between a 3.5" drive, a 5.25" drive and a GOTEK.
StarDot Forums member ChrisO was able to provide a solution to the Archive's problem. ChrisO had designed and had made a PCB which allowed him to attach 4 different disc drives to a BBC computer at the same time and to switch any of them to be drive 0/2 or drive 1/3. His unit behaved as a very versatile dual drive.
This was not exactly what the Archive needed, however. ChrisO was able to supply a blank PCB and this was adapted to fit the Archive's needs. No changes were made to the PCB itself. The components and switch needed to choose drive 1/3 and to light LEDs were omitted and only those components needed to switch 1 of 4 disc drives as drive 0/2 were used.
This article documents the building of this drive switcher.
The Archive had a spare, obsolete, 4 position Data Switch which was suitable to recycle for this project. Fortunately the PCB supplied fitted inside the switch box exactly.
The first job was to strip the switch box to leave the skeleton box.
The next stage was to cut out a rectangle to allow access to the drive connectors on the PCB and also the drive number links next to each drive connector and to drill holes for mounting the PCB to the rear of the switch box.
The rectangle was cut out and the holes drilled.
Afterwards the rectangle was filed square and all burrs removed. The rear panel was covered with black, self-adhesive vinyl to cover the holes and trim the rectangle cutout.
After this, the PCB was populated with the pull-up resistors, R1 to R4, the 34-way box connectors and the 3-pin drive selector links. The PCB was then fastened to the rear panel using 3mm bolts and 6mm standoffs. The multi-pole 4-way switch was also fitted.
Jumper wires were soldered from the switch contacts on the PCB to the rotary switch.
These jumper wires were coded yellow = drive A, white = drive B, green = drive C and red = drive D. Three rotors on the switch were needed.
After wiring the switch the case was re-assembled and the drive selector jumpers were placed on the links. All drives were set to be drive 0 as that was how they were originally set up.
This switch box will be a very useful addition here at the Archive and also when visiting various shows and events. It will allow a range of disc drive types to be used without frequent dismantling and reassembly.
The secondary archiving machine now has a 3.5" drive permanently connected as drive 1/3 (or drive 5 under ADFS) and any one of a 3.5", an 80T 5.25", a 40/80T switchable or a GOTEK connected as drive 0/2 (or drive 4 under ADFS).

N-ZnO/P-CuI heterojunctions are fabricated by growing undoped n-type ZnO thin films on p-type γ-CuI (111) single-crystal substrates using radio-frequency magnetron sputtering. The ZnO films are identified to be columnar structured with c-axis-preferred orientation by using X-ray diffraction and scanning electron microscope. Measurements of the energy band alignment of ZnO/CuI interface by using X-ray photoelectron spectroscopy result in a valence band offset of 1.74 eV and a conduction band offset of -1.37 eV, meaning a type-II band alignment at the interface. A typical diodelike behavior of the current-voltage curve indicates its possible applications in optoelectronics with further development.

The positive temperature coefficient (PTC) generally defines a substance in which electrical resistance increases when temperature increases. In present usage, PTC refers to certain semiconductive thermistors which have significant positive temperature coefficients over a defined range of temperatures. PTC's have varied appliance applications, including temperature sensing, current controlling, and heating. Only the heat generating attributes of PTC's are considered. Design engineers are first provided with background information on the technical aspects of the PTC semiconductive pellet, which is the actual heat generating source. Also presented is information regarding the selection of the medium to transfer the heat. Then PTC heaters are analyzed with regard to their usefulness in certain appliance designs. A summary of the best PTC design attributes is also given.


Observations are presented of the horizontal magnetic component of Schumann resonance intensities as simultaneously measured at locations in California and Western Australia during two separate intervals September 2–17, 1989, and April 14–21, 1990. For both intervals, diurnal variations of the average magnetic power over the lowest three modes of the Schumann resonances showed substantially different temporal profiles at the California and Western Australia stations, with interstation correlations of 0.51 and 0.39, respectively. A method is demonstrated for determining from these observations the average local time variation of the height of the D region. A height variation is obtained that is nearly identical for the respective analysis intervals, with a minimum height occurring at approximately 1300–1400 LT and a maximum-to-minimum height difference of roughly 50% of the mean. When corrected for the local D region height, the detailed diurnal intensity profiles over the analysis intervals display a greatly improved similarity, with interstation correlation coefficients increasing from 0.51 to 0.70 and from 0.39 to 0.82, respectively. Substantial agreement between the two stations after correction for D region height suggests that such observations could be used to monitor the global totality and variability of lightning, quantitatively and at time resolutions of the order of 10 min or less, in studies of global change. These results also suggest that with suitable instrumentation, in situ measurement of Schumann resonance intensities could provide a viable method for monitoring the global totality of lightning in other planetary systems capable of supporting the resonances, most notably Venus and Jupiter.

DS Smith is a leading provider of sustainable fibre-based packaging worldwide, supported by recycling and papermaking operations.
The company has invested in new camera technology that uses AI modelling capabilities on IBM Cloud, to assess the grade, quality and origin of the material arriving at the depot.
Stephanie Dalton, Innovation Manager, Recycling Division at DS Smith said: “Innovating to make sure we can improve the quality of material is key for driving up recycling rates. Exploring the latest technologies and digitalising our operations enables us to operate more efficiently and sustainably while simultaneously improving the quality of paper for recycling.”
“This collaboration with IBM is good news for our suppliers of recovered paper as it allows us to work even more closely to make sure they are optimising their recycling processes – ultimately improving recycling through reducing contamination,” she continued.
IBM and DS Smith: transforming recycling solutions with AI
Positioned in the ceiling of the depot, the cameras can identify whether the composition of the loose paper and cardboard meets strict quality guidelines before being sent for baling and recycling.
Achieved by teams from DS Smith and IBM Expert Labs, the state-of-the-art innovation improves the efficiency and accuracy of the process, which has traditionally been done using the human eye.
Janet White, Industrial Products Leader, IBM Consulting UK & Ireland, commented: “IBM’s collaboration with DS Smith represents the best of IBM’s capabilities to help organisations pursue their sustainability goals through digital modernisation. Using the power of hybrid cloud and Artificial Intelligence technologies to transform DS Smith’s recycling operation, this solution will significantly improve the quality of recycling output while reducing waste.”

As it is well known both atmospheric and mantle convection are very complex phenomena. The dynamical description of these processes is a very difficult task involving complicated 2-D or 3-D mathematical models. However, a first approximation to these phenomena can be by means of simplified thermodynamic models where the restriction imposed by the laws of thermodynamics play an important role. An example of this approach is the model proposed by Gordon and Zarmi in 1989 to emulate the convective cells of the atmospheric air by using finite-time thermodynamics (FTT). In the present article we use the FTT Gordon-Zarmi model to coarsely describe the convection in the Earth's mantle. Our results permit the existence of two layers of convective cells along the mantle. Besides the model reasonably reproduce the temperatures of the main discontinuities in the mantle, such as the 410 km-discontinuity, the Repetti transition zone and the so-called D-Layer.
Keywords: convective zone; earth’s mantle; finite time thermodynamics.

TimeCore from VISUAL PRODUCTIONS is a compact multitool that supports the topic of timecode with up-to-date hardware in a meaningful way. The TimeCore from VISUAL PRODUCTIONS is able to generate, convert and analyze time code signals and to react to time triggers. Furthermore, the TimeCore processes various non-timecode protocols.
Generating and following time code signals
The TimeCore can be configured as a time code master and in this case generates a stable time code signal. Alternatively, it can also be used as a time code slave. A large LCD display shows the currently running timecode in real time.
Convert time code
The TimeCore supports the transmission and reception of SMPTE- (LTC-), MTC- and Ethernet-based time codes. It is able to convert any of these time code signals. Even between different frame rates (24, 25, 29.99, 30 frames).
The TimeCore has an Ethernet port that can be used to access the internal web server. This web server allows the complete configuration of the device.
Show control protocols
Various show protocols are supported. For example UDP, TCP, OSC or MIDI. All these protocols can be used to start, stop or otherwise manipulate the timecode. Furthermore, sending these protocols can be assigned to a timeline.
The TimeCore understands the Art-Net and sACN protocols from the lighting domain and can therefore interact directly with the lighting console.
Cross-functional product family
The functionality of the TimeCore can be extended by combining it with other members of the Core family. The IoCore extends the TimeCore with additional GPI, 0-10V, GPO and RS-232 inputs and outputs. The CueCore extends the system with additional DMX-512 inputs and outputs and is able to record and playback a light show. The B-Station can act as a remote control.

Chennai: With the surge in demand for oximeters due to the COVID pandemic, the Tamil Nadu police warned people against downloading fake oximeter apps on their mobile phones, and said such applications may steal personal or biometric data from the phones.
People's apprehension during the pandemic is being exploited by the cybercriminals who are targeting the users with malicious links and applications that could steal personal information or biometric data like fingerprints.
"One such scam used by the cybercriminals is the fake oximeter app that claims to detect blood oxygen levels," the police said in an advisory.
Once the user downloads the fake app, which claims to test blood oxygen levels using fingerprint sensors, through a SMS, it asks permission to access various features in the mobile.
If permission is granted, then the cybercriminals could steal the sensitive data such as OTP, saved passwords, card details, photos, contacts and even the biometric information that could be used to access banking and other sensitive applications on the phone.
"These apps claim to measure blood oxygen level by placing the finger on the camera and illuminating the finger using torch light. During this process, the malicious apps could capture your fingerprint," the police said and warned that the fraudsters could also use the fingerprint data to replicate the thumb impression and authenticate Aadhaar Enabled Payment System (AEPS) transactions from the app users account.
Several states including Maharashtra and Gujarat have in the past warned people about such fraud apps. The police advisory claimed that SpO2 blood oxygen sensor is required to measure the blood oxygen levels accurately.
"This is not present in smart phones. Hence, users should be cautious of apps promising to measure blood oxygen levels using fingerprint sensors," the warning posted on the Tamil Nadu police facebook page said and appealed to the citizens to install applications from trusted sources.
However, if the biometric information is compromised, one should disable biometric authentication for AEPS transaction by visiting www.uidai.gov.in. The victims could file a complaint on www.cybercrime.gov.in....


We report on the feasibility study of a mid-infrared (8-18 µm) spectro-imager called THERMAP, based on an uncooled
micro-bolometer detector array. Due to the recent technological development of these detectors, which have undergone
significant improvements in the last decade, we wanted to test their performances for the Marco Polo R ESA Cosmic
Vision mission. In this study, we demonstrate that the new generation of uncooled micro-bolometer detectors has all the
imaging and spectroscopic capabilities to fulfill the scientific objectives of this mission.
In order to test the imaging capabilities of the detector, we set up an experiment based on a 640x480 ULIS micro-bolometer
array, a germanium objective and a black body. Using the results of this experiment, we show that calibrated
radiometric images can be obtained down to at least 255 K (lower limit of our experiment), and that two calibration
points are sufficient to determine the absolute scene temperature with an accuracy better than 1.5 K. Adding flux
attenuating neutral density mid-infrared filters (transmittance: 50%, 10%, 1%) to our experiment, we were able to
evaluate the spectroscopic performances of the detector. Our results show that we can perform spectroscopic
measurements in the wavelength range 8-16 µm with a spectral resolution of R~40-80 for a scene temperature <300 K,
the typical surface temperature of a Near Earth Asteroid at 1 AU from the Sun.
The mid-infrared spectro-imager THERMAP, based on the above detector, is therefore well suited for the Marco Polo R

NOTE about Mx5 Headlight Wiring Diagram
What’s Wiring Diagram
A wiring diagram is a design that uses abstract reflective symbols to display each of the interconnections of components at an exceedingly system. Wiring diagrams are made up of a few items: symbols which represent the ingredients within circuitlines and lines which represent the relations between them. Accordingly, from wiring diagrams, you understand the relative place of the ingredients and the way they may be linked. It’s a language engineers will need to learn any time they work on electronics projects.
Wiring Diagram VS. Schematics
It’s simple to receive confused by wiring diagrams and schematics. Wiring diagrams mostly reveals the physical location of connections and components inside built circuit, rather than always in logic order. It highlights around the layout from the cables. Schematics highlight on how circuits work logically. It reduces integrated circuits to sub-components to produce the system’s functional logics easier to understand. It is most successful for studying the general operation of a program.
How to Read Wiring Diagram
To see a wiring diagram, is truly a program have to understand exactly what basic components are included in a very wiring diagram, and which pictorial symbols are utilized to represent them. The typical components in a wiring diagram include ground, energy, wire and connection, output devices, switches, resistorsand logic gate, lighting, etc.. A list of electrical symbols and descriptions is available about the”electrical symbol” page.
A line signifies a wire. Wires are utilized to connect the components together. All points throughout the wire are connected and identical. Wires on several areas must cross each other, but that won’t indicate they can connect. A black dot is used to tip that the injunction of two lines. Usually different colours are utilized to differentiate the wires. There should be a legend concerning the wiring diagram to notify you what each colour means.
Types of Connection
Normally circuits exceeding two components have two basic kinds of connections: series and parallel. A series circuit is often a circuit where components are attached along only one route, so the current flows through a single component to reach the next one. In a series circuit, voltages add around to all those elements attached within the circuit, and currents are the same through all components. In a parallel circuit, every unit is directly connected to the power source, so every system receives the same voltage. The present in a very parallel circuit flows across each parallel branch also re-combines once the branches meet again.
Tips to Draw Good-looking Wiring Diagrams
A fantastic wiring diagram must be technically correct and clear to see. Be careful of all of the info. For instance, the diagram must demonstrate the very best direction from the positive and negative terminals of every component. Use the appropriate symbols. Learn the meanings in the basic circuit symbols and judge the best ones to work with. Some of the symbols have close look. You must find a way to inform the differences before applying them. Draw connecting wires as straight lines. Use a dot to point line junction, or use line jumps to signify cross lines which aren’t linked. Label components including resistors and capacitors making use of the values. Be certain that the text positioning appears clean. In general it’s great to place the positive (+) supply to the top, and also the negative (-) source in the base, in addition to the logical stream from left to right. Try to clean up the positioning reducing wire crossings.

Information on global land use and land cover is crucial when studying changes in biodiversity, food security, climate, and many other contemporary issues, but suffers from widespread uncertainties. We - quantify and address these issues.
To achieve this, we are mobilizing ground-truth information from hundreds of sources worldwide, generated through field and crowdsourcing campaigns. To close gaps in data-scarce regions, we collaborate with hundreds of regional data-holding scientists on developing a FAIR and Open-Access database. On the top image to the right, we see the latest status of this effort. The map shows the global distribution of samples collected by the Macroecology & Society lab, composed millions of land cover and land use observations.
Using these integrated data, we detect, quantify, map, and ultimately aim to reduce uncertainties in land-cover land land-use, as well as in various derived environmental data. For example, we are developing a framework for uncertainty quantification of remotely sensed environmental data that accounts for scale mismatches between samples and pixels, such as seen on bottom image to the right. The image shows the spatial mismatch between the pixels of multiple, gridded land cover datasets, which create thematic uncertainties.


The Sticky Pipeline Advance bit in the DBGDSCR register enables the debugger to detect whether the processor is idle. The CPU does not implement accesses to DBGDRCR via the debug APB interface, so the debugger is unable to clear the Sticky Pipeline Advance bit.

Robust thin film solid oxide fuel cell
Among the major fuel cell chemistries, Solid Oxide Fuel Cells (SOFCs) are considered most desirable due to their high energy conversion efficiency, fuel flexibility, and contaminant tolerance. Conventional solid oxide fuel cells operate at 800°C - 1000°C, requiring expensive non-corrosive materials. The technology developed in the Ramanathan Lab allow SOFCs to operate at low temperatures of 450°C - 550°C (and potentially lower), providing efficiency gains while allowing use of lower cost materials and simpler packaging. The technology captured here allows for easy fabrication of electrodes using industry standard silicon wafers and commonplace micro-fabrication techniques. The thin nature of the electrodes also allows for potential gains in volumetric power density at both small and large scale.
• Demonstrated highest power density to date among thin film micro solid oxide fuel cells with oxide cathodes (in the 150mW/cm2 range), targeting 300-500 mW/cm2 at 400-500°C range and below
• Demonstrated largest mechanically stable fuel cell area among thin film micro-SOFCs
• Demonstrated highest total power output from single thin film fuel cell area
• Demonstrated robust fabrication process (>90% yield)
Intellectual Property Status: Patent(s) Pending
A surge in energy consumption of portable electronic devices has increased interest in fuel cells as alternitave mobile power sources. Fuel cells provide higher total energy for a given size or weight than batteries and unlike batteries can be replenished instantaneously. This portable fuel cell market is estimated to hit $1 billion dollars globally in the next 5-7 years.


LiDAR odometry and localization has attracted increasing research interest in recent years. In the existing works, iterative closest point (ICP) is widely used since it is precise and efficient. Due to its non-convexity and its local iterative strategy, however, ICP-based method easily falls into local optima, which in turn calls for a precise initialization. In this paper, we propose CoFi, a Coarse-to-Fine ICP algorithm for LiDAR localization. Specifically, the proposed algorithm down-samples the input point sets under multiple voxel resolution, and gradually refines the transformation from the coarse point sets to the fine-grained point sets. In addition, we propose a map based LiDAR localization algorithm that extracts semantic feature points from the LiDAR frames and apply CoFi to estimate the pose on an efficient point cloud map. With the help of the Cylinder3D algorithm for LiDAR scan semantic segmentation, the proposed CoFi localization algorithm demonstrates the state-of-the-art performance on the KITTI odometry benchmark, with significant improvement over the literature.

The plasma around comet 67P/Churyumov–Gerasimenko showed remarkable variability throughout the entire Rosetta mission. Plasma boundaries such as the diamagnetic cavity, solar wind ion cavity and infant bow shock separate regions with distinct plasma parameters from each other. Here, we focus on a particular feature in the plasma: warm, slow solar wind protons. We investigate this particular proton population further by focusing on the proton behaviour and surveying all of the Rosetta comet phase data. We find over 300 events where Rosetta transited from a region with fast, cold protons into a region with warm, slow protons. We investigate the properties of the plasma and magnetic field at this boundary and the location where it can be found. We find that the protons are preferentially detected at intermediate gas production rates with a slight trend towards larger cometocentric distances for higher gas production rates. The events can mostly be found in the positive convective electric field hemisphere. These results agree well with simulations of the infant bow shock (IBS), an asymmetric structure in the plasma environment previously detected on only 2 d during the comet phase. The properties of the plasma on both sides of this structure are harder to constrain, but there is a trend towards higher electron flux, lower magnetic field, higher magnetic field power spectral density and higher density in the region that contains the warm protons. This is in partial agreement with the previous IBS definitions; however, it also indicates that the plasma and this structure are highly non-stationary. For future research, Comet Interceptor, with its multi-point measurements, can help to disentangle the spatial and temporal effects and give more clarity on the influence of changing upstream conditions on the movement of boundaries in this unusual environment.


It’s All in the eyes!
Predictive & Analytic AI for Visual Data
Low-cost gaze-point tracking is our key value-point, and is being used in multiple in-progress trials.
Also used in our predictive health solution, we specifically focus on the precise tracking and movement of the eyes. Our specific technology is able to use comparatively low resolution video while still retaining very high accuracy. This allows us to apply precise eye tracking to general devices such as smart phones and web cameras.
Through the introduction of our 2D "WeKare" product, we are able to process the precise location and gaze point of a user's eyes, head and body using relatively low resolution video. This data is then used to predict and estimate the risk factor of a large battery of chronic illnesses and ailments, primarily related to the neurological system.
Through the introduction of our 3D "WeKare" product, we utilize eye movement data to detect warning signs of Alzheimer’s while users interact with our Mixed Reality Content.

|Sun Sounds listener Bob Burrows |
and wife Carol
This month, with a grant from Virginia G. Piper Charitable Trust, Sun Sounds upgraded Bob’s analog radio to The Narrator, a new, accessible AM/FM/HD radio created by Insignia, Best Buy’s private label brand. The Narrator’s voice prompts help people with visual impairments tune the radio, set the clock, and set the alarm. “I love it,” said Bob, “It tells me exactly what button I’ve touched. And the digital signal from Sun Sounds has no interference. It sounds great. Now my wife Carol doesn’t have to find radio stations for me!”
Sun Sounds of Arizona first brought the idea of a digital talking radio to Best Buy’s development team five years ago, citing the number of American consumers with vision loss (an estimated 25 million) and the aging baby-boomer population. Since then, Best Buy has worked closely with David Noble, Development Director at Sun Sounds of Arizona, to bring a universally-designed, digital radio to the market. “Because this radio talks, anyone with low vision can use it right out of the box. But it is also feature-rich for the sighted consumer, at a price point that’s affordable.” says Noble.
When the Narrator came to market, Virginia G. Piper Charitable Trust seized the opportunity to help older Valley residents with vision loss access the newest digital radio technology. “Providing access to a reading service via the latest technology aligns with Piper Trust’s mission of making our communities more livable and increasing independence for older adults,” said Carol Kratz, Program Director with Virginia G. Piper Charitable Trust. With grant funding from Virginia G. Piper Charitable Trust, 200 Sun Sounds listeners will receive a free upgrade to the Narrator this summer. Other listeners can purchase the Narrator talking radio on Best Buy’s website.
Sun Sounds of Arizona broadcasts on KBAQ 89.5-HD 3, and is a service of Rio Salado College.

"Nick Barendt, executive director of the Institute for Smart, Secure and Connected Systems (ISSACS) at Case Western Reserve University, illustrates the challenge of protecting Internet of Things devices by comparing them to more traditional IT assets."—Source: EdTech Magazine
WHY THIS MATTERS:
As the use of internet of things devices continues to climb on campuses, institutions are examining the cyberthreats connected tech can pose if left unchecked on campus network. Case Western Reserve University's Nick Barendt notes that the IoT "spreads your surface area of attack infinitely," adding, "Anyone can walk up to a device, if they can access it, and either brute-force attack the device or use the compromised device to launch other types of attacks."


GPS needs to be more accurate and current.
GPS should update every 10 minutes and needs to be more accurate with current position.
Thanks for the continued feedback on this issue. Like Cliff said before, a lot of this is reliant on the device of the user itself for the accuracy of the GPS.
For anyone with any questions or issues about that aspect I do recommend reaching out to our support team via chat on the website, email (email@example.com), or phone (800-828-0689).
GPS updating on a more frequent basis is something that could be done in the future. Right now we feel like the 15 minutes is a good balance of information provided while keeping the battery usage low as well. But keep voting and this will be something we look at!
Karen Wagner commented
I am using the app for my self (as an HR person) and the accuracy is horrible!! I don't leave the office except to go home and it has my GPS location all over. Now I'm not sure what to believe on the other employees tracking!! I don't want to mess with other's pay.
Being a stand alone non corrected GPS signal..... the accuracy of position will not improve. Consistent pinging of a users phone will


What Is An Audio Oscillator?An audio oscillator is an electronic instrument used to test sound equipment. The HP model 200A was a resistance-capacitance audio oscillator that represented a significant advancement in oscillator technology at the time. The Hewlett-Packard oscillator used an incandescent bulb as part of the wiring scheme to provide variable resistance.
Who Were William Hewlett and David Packard?William Hewlett and David Packard were undergraduate engineering students at Stanford University when they first met. They formed the Hewlett-Packard Company in 1939 and their first product was the audio oscillator invented by William Hewlett in 1938.
David Packard thought up the name "HP Model 200A" to make the company appear more established. Hewlett-Packard, now famous world-wide, started out of William Hewlett's garage in Palo Alto with a capital investment of $538 and a Sears-Roebuck drill press.
Hewlett-Packard's First Famous CustomerIn 1940, the Walt Disney Company ordered eight Model 200B oscillators and used the equipment to test the various channels, recording equipment and speaker systems in the twelve specially-equipped theaters that showed the Disney film Fantasia.
William Hewlett was granted United States patent 2,268,872 for his oscillator on January 6, 1942.

An analytical optimization is proposed for the sensitivity threshold of low-frequency search coil magnetometers employing disk-shape flux concentrators. The optimal diameters of the core and the wire are found for a given set of the optimization parameters: frequency, search coil volume and aspect ratio, relative permeability of the core and the flux concentrators, and the noise of the preamplifier. The proposed analytical optimization allows an immediate analysis of the theoretical limits of the magnetometer sensitivity threshold. An approximation is obtained to simplify and clarify the relationship between the minimum possible sensitivity threshold and the optimization parameters. Measurements performed with an experimental magnetometer model confirm the optimization.

The system of one master-radar sensor and several slave-radar sensors is a solution for measuring discharge in wide rivers with inhomogeneous distribution of flow velocity. This system measures velocity at several spots throughout the whole water cross-section, ensuring a high accuracy of discharge measurement even in wide water bodies.
One advantage of this system is its high accuracy, which makes it ideal for use in rivers with inhomogeneous velocity distribution. Additionally, the system requires only one water level measurement and multiple individual velocity measurements, making it a cost-effective solution.
The system utilizes the well-proven RQ-radar technique for non-contact measurement, ensuring a maintenance-free system that is flood-proof. No structural work is necessary in the water, making installation simple and easy. The system also recognizes flow direction and hysteresis effects and can measure in tidal waters and backwater situations.
Another advantage of the system is its ability to measure even where weed growth prevails, and the sensor is not affected by turbidity. The measuring range is 0.08 to 16 m/s, depending on the flow conditions, and the system can provide analog outputs from 4 to 20 mA.
Overall, the system of one master-radar sensor and several slave-radar sensors is a reliable and accurate solution for measuring discharge in wide rivers with inhomogeneous distribution of flow velocity. Its non-contact measurement technique, low maintenance requirements, and simple installation make it a valuable tool for river management and monitoring.

LONDON The possibility of combining the rich color gamut of organic light emitting diode (OLED) displays with enhanced flexibility is opened up by an academic paper on a liquid-OLED display in a recent issue of Applied Physics Letters.
Denghui Xu and Chihaya Adachi of the Center for Future Chemistry, Kyushu University, Fukuoka, Japan, have reported an OLED with a liquid host of 9-(2-ethylhexyl)carbazole (EHCz) doped with a guest emitter of 5,6,11,12-tetraphenylnapthacene, otherwise known as rubrene.
To date OLED displays have been made in the solid-state and have the advantage over liquid crystal displays of not requiring a back-light. As OLED is emissive it can be energy efficient and be made very thin. However, manufacturing infrastructure supports cost-efficient LCD manufacture over a large range of sizes while OLED displays have been kept to small size applications.
"Although OLEDs have mainly used complete solid-state organic thin films and partly liquid crystals, no attempt to examine neat liquid organic semiconductors has been reported, except some reports using polymer solutions and solution-phase electroluminescent devices," the authors state in the paper.
As well as being useful for flexible emissive displays liquid semiconductors could also be useful more generally to enhance the reliability and longevity of organic semiconductor systems such as FETs and solar cells.
The authors propose circulated-OLEDs in which the liquid organic semiconductor material is circulated or refilled into the active emitting layer so that fresh organic semiconductors can be supplied.

GPS Active SteadyShot Feature
A built-in global positioning system (GPS) locator allows satellite navigation data to be recorded directly onto footage for reference or posting on popular internet mapping systems. GPS data can be invaluable when searching for footage or to provide evidence of where and when footage was recorded. Active SteadyShot feature is a new, enhanced image stabilization system that provides a powerful shake-reduction capability, vital for handheld usage. Additional stabilization is provided by the increased optical lens coverage area and by improved detection with state-of-the-art compensation The revolutionary AVCHD recording format, which utilizes the MPEG-4, AVC/H.264 video codec, allows users to record HD video footage onto random access media. Its intelligent and sophisticated algorithm makes AVCHD a highly efficient compression format ideal for memory recording and IT-based editing.
The "G Lens" provides great picture quality and versatility with a wide angle of 29.5 mm (equivalent to 35 mm film) and a 20x high quality zoom. Two ED (extra-low dispersion) glass elements reduce chromatic aberrations caused by differences in light refraction to minimiz e color fringing. The advanced 10-group, 15-element lens structure also includes a compound aspheric lens for images that are crisp and clear, even when shooting videos at a high zooming ratio. Advanced Camera Features Sony-exclusive High-performance "G Lens" Other Superb Features of the Optical System FOCUS IRIS ZOOM Three ND filters Natural-touch Lens Operation The focus, zoom and iris ring are positioned on the lens barrel, and this design offers the same operability as general interchangeable lenses. Focus, zoom and iris control can all be managed easily. Six-blade Iris SThe six-blade iris diaphragm is nearly circular, enabling the creation of an extremely beautiful background blur. Built-in ND filters SThe HXR-NX5U is equipped with three built-in ND (Neutral Density) filters - 1/4, 1/16, 1/64 - which help to vary the depth of field with iris control.
The three state-of-the-art 1/3" Exmor CMOS sensors with a ClearVid array ensure high resolution, high sensitivity, a wide dynamic range, and excellent color reproduction. The quality of this imaging system has earned an excellent reputation in the industry, and is of course fully realized in the new HXR-NX5U. S Exmor Technology Noise Reduction System Multiple A/D (analog-to-digital) converters on each pixel row convert analog signals to digital as soon as they are generated, unlike traditional technology that only provides one A/D converter on each chip. Exmor technology can eliminate the influence of external noise that enters the signal chain during transfer to the A/D converter, resulting in high-quality digital signals with extremely low noise. This significantly enhances shooting in low-light environments with a sensitivity of just 1.5 lux.* * At 1/30 shutter, auto iris, and auto gain. S High Sensitivity and Resolution with Sophisticated Techniques CMOS sensors equipped with a ClearVid array achieve a bigger sensor pixel size than ordinary image sensors, and this leads to high sensitivity. Furthermore, a unique interpolation technique from Sony utilizes the 45-degree rotated pixels on each chip, increasing resolution. The powerful combination of these two sophisticated techniques explains why Sony picture quality has such an excellent industry reputation.

The HXR-NX5U is the world's first AVCHD professional camcorder with an internal GPS. This important new feature enables users to find the same shooting location when, for example, they need to revisit a location for extra shots that must match existing footage. GPS data is embedded in AVCHD video data files. Mapping data can be created using bundled Content Management Utility software. Also GPS data can be extracted from video files, using Content Management Utility software, in a commonly used latitude/longitude NMEA data format. This GPS information can be used in several applications. Location Simplification with Cutting-edge GPS Technology Content Management Utility Software Display GPS data on the map
A new feature of the HXR-NX5U is Active SteadyShot. This useful feature effectively reduces hand-held camera shake. The improvement is particularly noticeable when using wide-angle framing. It is an essential feature when holding the camcorder by hand, and especially for projects that are recorded mainly in the field. It is also ideal when the subject is moving and must be followed, for example in news gathering or at weddings. Shooting from inside a moving vehicle is another useful application for the Active SteadyShot feature. It significantly reduces the need for external stabilization systems. Improved stabilization allows the user to concentrate more on composition and shot transition, rather than worry about how to stabilize the camera. Depending on the shooting environment, users can select normal SteadyShot feature or Active SteadyShot feature for hand-held applications. When not in use, the stabilization feature can be easily switched off. Shoot and Walk with the New Active SteadyShot Feature Without Active SteadyShot Feature With Active SteadyShot Feature
The HXR-NX5U is also the first Sony professional camcorder designed to record directly onto consumer memory cards. These cards are affordable and easy to find. This general versatility is especially handy when a user suddenly needs extra memory - something that happens quite often when shooting a documentary or news report on the move. Also, memory cards are very compact and easy to handle. Many devices can accept these memory cards allowing easy playback. Files can be copied
There are major advantages of Memory Recording Recording Time on a single memory media including Easy Viewing of Recorded Footage, Fast Ingestion to a Computer and Easy Playback Another new feature is continuous recording between two memory card slots. The new HXR-NX5U camcorder automatically cycles between the dual memory slots. When using two, 32-GB memory cards, six hours of continuous HD footage can be recorded. If a longer continuous recording time is required, the user simply waits until the first card is full and recording has relayed to the second card, before ejecting the first card and inserting a new blank memory card. This procedure can be repeated as required, extending continuous recording for a sufficiently long time. from a memory card to any available computer, instantly backing up valuable data.


The development of weapons that can travel at hypersonic speeds is becoming a high priority to the US Air Force. A key technology needed for the continued development of these propulsion systems is the ability to cool the combustor by flowing fuel through channels machined in the walls.
Aircraft and missiles capable of rapid global strike and reconnaissance must fly at hypersonic speeds to achieve their performance goals. Future air-breathing hypersonic aircraft and missiles are expected to be powered by supersonic combustion ramjet (scramjet) engines.
The Army is very interested in accurate simulations of combustion in devices such as rockets and gas turbines, Otto and Diesel cycle IC engines, scramjet engines, rotating detonation engines, etc.
The surfaces of rocket engines are exposed to high pressure combustion products at temperatures up to 6000?F. Regenerative cooling can cause coke to form on the heat exchanger surfaces.
The development of new, robust, lightweight life support systems is currently a crucial need for NASA in order to continue making advances in space exploration, particularly in the development of Lunar outposts.
Reducing the allowable concentration of carbon dioxide (CO2) in spacecraft is a critical need for NASA.
Scramjet engines, which likely will provide the next generation propulsion capability, operate at extremely high temperatures and air velocities, conditions that are very difficult to reach in a laboratory.
Reaction Systems, Inc. has developed a new line of robust high temperature ceramic choked flow venturis for use in oxidizing and reducing atmospheres at temperatures up to 2700?F (1480?C).
