Graduate students Kyriakos Vattis and Isabelle Goldstein working with BTPC/CFPU affiliated faculty member Prof. Koushiappas investigated the possibility of the light object being a primordial black hole, that is a black hole formed right after the big bang.
In an exploratory study, graduate students Kyriakos Vattis and Michael Toomey, together with Prof. Koushiappas (BTPC/CFPU affiliated faculty member) explored whether convolutional neural networks can be used to extract the astrometric signature of dark matter.
Graduate student Kyriakos Vattis together with BTPC postdoc Steven Clark and Prof. Koushiappas (BTPC/CFPU affiliated faculty member) explored the cosmological effects of dark matter that decays to light particles in recent times in the context of the solving the Hubble tension.


Is there a way to talk on Android Zello when it's running in the background?
Zello will work with wired headset while in the background with the screen off. Just make sure to adjust these settings:
1. In Zello Options > Push-to-talk button> tap drop down menu and then press the wired headset button.
2. In Zello Options > Push-to-talk button action to Toggle
3. In Zello Options > Push-to-talk button check Handle headset buttons when in the background
Then you should be able to use the button on the wired headset in a toggle mode -- press once to start talking and agan to stop. Hold to talk mode will typically not work because of design of wired headsets-- they short the mic when button is depressed.
The same may work with Bluetooth headset however the compatibility vary between different Android devices and headsets.

Implementing an Efficient Minimum Viable Product in Industry 4.0
From the introduction of 3D printing, smart data visualization, and location tracking to Big Data, IoT, and augmented reality –Industry 4.0 has come a long way to become as advanced as it is right now. So 4.0 startups must be engaging, authentic, and up to date. And that’s where a minimum viable product (MVP) comes in as a real game-changer, allowing you to test out the basic idea of a new product among the real target audience and decide whether it’s worth continuing to work on.


Throughout history, scientists have gathered together to pool ideas and theories in order to combine minds and advance in the field. With today’s computer technology, it’s even easier to share information across the world. One way of doing this is by using open source software, which often comes as a simple download. The open source movement allows anyone to add or edit source code whether you are a student or administrator. The following list pertains to education open source software that specializes in science.
- Geographic Information Systems, also known as GIS, is a computer system for displaying data, capturing, checking, manipulating, storing, integrating, and analyzing data related to specific positions on the Earth’s surface. The software is generally used by scientists for handling maps.
- Plotting software packages that are open source can be used for semi-log plots, contour plots, mesh plots, pie charts, bar charts, and X-Y plots, among others.
- Microscope image processing open source software is used by biologists, chemical engineers, druggist, and researchers among others to analyze images from microscopes.
- Molecule viewer open source software is available for commercial, academic, and government researchers who wish to visualize and share their molecular information using industry standard formats.
- Molecular dynamics open source software forms simulations on the computer in which molecules and atoms interact, showing the motion of the particles. Scientists use this software to see and study molecules and proteins.
- Bioinformatics is used in molecular biology as an open source software option for studying informatics processes which occur in biotic systems. Since the 1980s, it has been used particularly in the study of genetics.
- Cheminformatics is open source software that allows chemists and pharmaceutical companies to share and manipulate information that relates to compounds.

Report: Some new smartphones have worse battery life than old counterparts
A new report from The Washington Post suggests some newer smartphones get worse battery life than their older counterparts.
Specifically, the Google Pixel 3 and Apple iPhone XS tested worse than their previous models.
The Samsung Galaxy Note 9 tested the best of all the Android phones on the list.
Over at The Washington Post, journalist Geoffrey A. Fowler conducted a series of battery life tests on popular smartphones, including both Android and iOS devices. Fowler found that some new devices actually fared worse than their older counterparts in his tests.
One would usually assume that the newer a smartphone is, the better its battery life will be. However, Fowler found that in a few cases, the older device fares better than the newer device when it comes to battery life.
For Android, Fowler found that both the Google Pixel 2 and Google Pixel 2 XL tested better than the Google Pixel 3. However, both second-generation Pixels didn’t do as well as the Google Pixel 3 XL.
Editor’s PickSamsung Galaxy Note 9 battery review: Huge, but enough?In most metrics, the Samsung Galaxy Note 9 is an impressive flagship phone. It’s got a great camera, it’s very powerful, and it’s one of the best Android phones on the market. Perhaps most importantly, …
For iOS, it appears the Apple iPhone XS didn’t fare as well as the iPhone X. In fact, the iPhone 8 Plus handily beat the iPhone XS and XS Max.
Remarkably, the iPhone XR topped the entire list when it comes to battery life, beating out the top Android device — the Samsung Galaxy Note 9 — by a slight margin.
Check out Fowler’s full chart of results below:
The Washington Post
Despite the anomalies of the Pixels and iPhones, most of the results do tend to match with the idea that newer phones get better life than older phones. The results also suggest bigger phones get better battery life, which makes sense because they usually have bigger batteries.
To conduct his test, Fowler used a light meter to set every device at the exact same brightness level. He then used a script to make the devices endlessly scroll through web pages. The results you see above are how long it took for each device to go from 100 percent battery to empty.
What do you think? Have you noticed worse battery life on a newer device as compared to a previous model in the line? Let us know your experiences in the comments!

GoTek Floppy Emulator
With good floppy drives hard to come by, to say nothing of blank diskettes, an alternative is needed. A GoTek drive with Flash Floppy firmware update is capable of reading and writing disk formats as used by SK*DOS, REX and OS9. The GoTek uses USB memory sticks to store images of floppy disks and can hold thousands of disk images on a single USB stick. The images can be emailed as well as downloaded over the internet. We supply boot disk images for the GoTek, so you will need to have at least one GoTek in your system. GoTek's are available from Amazon for about $30; the Flash floppy firmware is free; an OLED display adds a few dollars but is a necessity so you can see the name of the disk you are selecting. Otherwise you are selecting the disks by a number and not by the name of the disk image.
The instructions for flashing the firmware and adding the OLED display can be found here - https://github.com/keirf/FlashFloppy/wiki
You may use a real floppy drive with a GoTek should you have a need to read or write real diskettes.
The Humbug Monitor will support RS232, Monochrome and CGA monitors. VGA is not supported. With the optional HD floppy controller all disk sizes between 320K and 1.4MB are supported. Hard disk support is either for the WD1002A-HDO or Western Digital XT MFM controller cards.
Rex will support RS232, CGA, EGA and VGA. The list of EGA and VGA cards supported has been lost. All CGA cards should work but only cards containing a ET4000 chip will work and not all cards containing a ET4000 will work. Rex will support floppies from 320K to 1.4MB. 1.2MB/1.4MB requires the use of the FD-3765 HD floppy controller. HD support is either a XT-IDE controller card that was produced in the 90's or a Western Digital MFM XT controller card.
Hard Disk support for IDE drives for REX or SK*DOS
There is no support for the PT-XTIDE controller card at present. Source code for both REX and SK*DOS is available and it would be possible to modify these operating systems to support the PT-XTIDE controller card. Source code for the PT-XTIDE controller for OS9 could be used as a guide.
OS9 will work with RS232, Monochrome, CGA, EGA and VGA cards. The list of EGA and VGA cards supported has been lost. All CGA cards should work but only cards containing a ET4000 chip will work and not all cards containing a ET4000 will work.
OS9 hard disk drivers have been updated to support modern IDE drives with the PT-XTIDE controller card. A new boot ROM allows OS9 to boot from this controller.
The XTIDE controller card will support SD,CF, SSD, SATA or rotational hard drives. You will need an appropriate adapter to connect between the IDE port and your drive choice. For example a SD memory card to IDE adapter. Numerous examples of this adapter can be purchased on Amazon for between $10 and $20. SATA to IDE adapters are also readily available on Amazon.

The demand for advanced technology in IoT has proven critical these past two years in the multifamily and student housing communities. Many communities offer some form of smart home technology for resident attraction and retention which enhance the resident experience. More and more owner/operators are seeing the value of smart home automation within their communities for residents while making work easier and more efficient for their onsite teams. In fact, the recent survey results from NMHC/Grace Hill, residents ranked their preferences of smart home devices with 60% stating smart locks to the highest ranking of 70% preferring smart thermostats included in their communities.
What is IoT?
Let me break it down for those of you that may not be totally sure as to what Internet of Things (IoT) means. IoT is the network of physical objects that are embedded with sensors, software, and other technologies for the purpose of connecting and exchanging data through commands over the internet and can perform one or multiple sets of tasks with other devices and systems over the internet.
The quest for a Wi-Fi network with superior capacity and access for multiple devices per resident with optimization for in-unit and smart home IoT that also include the community areas has become owner/operators’ main priority. Brett Lindsey, CEO of Everstream and chairman and founder of Snip Internet states, “Building owners are looking for operational efficiencies they can use,” he says. “They are going to be looking for ways to use IoT to drive efficiencies in the buildings, so it’s even more important to have quality bandwidth available.”
Is Smart Technology for New Buildings Only?
Leading industry smart tech service providers can install the technology in new builds as well as retrofit existing buildings. While installing smart technology for apartments does not require the building to be new or have a top tier technology infrastructure, it does require a strong, reliable Wi-Fi to keep the multiple devices operating at all times. Some communities provide hubs that run on cellular connectivity to help keep the devices connected when Wi-Fi is not reliable or available. A key to optimal performance that owners and operators should be aware of while making this significant investment in their communities is sufficient bandwidth circuit size, user speeds and having ample wireless access points in each unit.
Devices, such as security cameras typically operate on the property network connection, which use fiber and ethernet to operate and typically will not impact a residents’ quality of experience when connected. Essentially, smart devices will not impact network performance as one may have originally thought. Owners and operators can rest assured that their residents are able to get the most out of the network performance while enjoying the many benefits of smart technology within their communities.
Expectations For the Future
As IoT continues to grow and smart home technology becomes more prevalent, property owners and operators will find it necessary to make sure their community’s network can accommodate these changes. The amount of data each smart device gathers and transmits will increase as innovation and technology continues to develop, which in turn contributes to the need for a robust and stable network. Statista reports that by 2026 the number of IoT-connected devices will increase by 6.58 billion at a total of 18.15 billion globally connected devices.

Although cars already had headlights from the beginning, lighting is one of the fields in which most progress has been made, especially in the last 15 years. This is how the technology of light in the car has evolved.
Almost 150 years have passed in which lighting has evolved a great deal. More specifically, two elements have progressed significantly: the headlamps and the light source. For the evolution of the first, the appearance of computers and design programs has been decisive.
Computers have allowed a much more accurate study of geometries and the headlight reflectors’ arrangement. Computers have also allowed the development of materials and molding machines that enable these increasingly complex shapes to be mass-produced.
As for the light source, there have been two enormous turning points in its evolution. The first was the use of electricity and the second was the development of high-brightness LEDs. So today, we’ll shed some light on how your vehicle’s headlights work, from the first oil lanterns to the current lasers and LEDs.
Via Cars Guide
The advancement of technology has allowed the lighting in cars to adapt to the needs of drivers. Current headlights have designs that favor greater range and visibility during the journey and illuminate specific points without damaging the driver’s eyesight. However, for vehicular lights to become what we know them today, they had to go through several processes.
It all started at the end of the late 19th century. Back then, cars mounted headlights that had an internal lantern or made use of the combustion of oil or acetylene gas to give the driver visibility of the road at night. However, effectively lighting the route was a complex task for those large lamps.
For this reason, the first incandescent light bulbs appeared at the beginning of the 20th century with the rise of electrification. These bulbs generated light by passing an electric current through a metallic filament that, when reaching high temperatures, emitted radiation perceptible to the human eye.
This form of lighting lasted several years until halogen headlamps appeared in the 1960s. This new headlight technology positioned itself on the market thanks to its range of up to 100 meters. Halogen light bulbs work under the same principle since they are made of a glass bulb that resists high temperatures and a metal filament.
The development of new lights continued, and in the 1990s, xenon headlights (Xe) were released. This new technology produced bluish light through a quartz bulb with two tungsten electrodes inside that led to a chamber filled with gas (Xe) and salts of sodium (Na) and mercury (Hg).
Shortly after, in the early 2000s, LED (Light Emitting Diode) lights began to be used in automobiles. They were adapted for automotive lighting due to their small size, long-range, superior duration, and low energy consumption. These characteristics have led it to be mandatory for some vehicles in Europe.
OLEDs (Organic Light Emitting Diode) were introduced in 2016 as a signaling strategy to warn motorists about the decisions made by other drivers, such as turning or braking.
Automakers like Audi and BMW have implemented technology based on laser lights. This new type of headlights offer a range of up to 600 meters, 30 percent more energy savings than LED, and longer life.
Likewise, Mazda has recently developed intelligent automobile lighting mechanisms that help increase safety. For example, Mercedes Benz introduced in 2018 its Digital Light technology. The lights can project from real-time guidance and navigation information, such as a HUD over the road, as well as details of road conditions, weather, and traffic warning symbols.

Types of Headlights Most Commonly Found in New Vehicles (5 Years or So)
LED. Compared to its predecessor, the light bulb, and its direct competitor, the xenon headlamp, the “Light Emitting Diode” (LED) has several advantages that both you, as a driver, and other road users will benefit from.
First, they are much more durable, with a useful life of ten thousand hours of operation. Second, they consume less electricity, thanks to their high efficiency, offering the same light output as conventional bulbs. Especially the oncoming traffic will thank you for the setup. Third, light distribution between various sources makes LED headlights glare much less. Even high beams will hardly bother road users.
LED headlights have become standard across the new vehicle range, and they are both bright/effective, and affordable. Pairs of 9005 LED bulbs range from $29 to $70 from SuncentAuto (online auto parts store), for example.

Headlights In Modern Luxury Cars
Many modern high-end cars today are equipped with the latest technology in headlights. Of course, we are talking about laser headlights.
Introduced in 2014 by Audi, BMW laser headlights emit light with a brightness four times higher than a conventional LED. The lighting range is about 600 meters, compared to halogen lamps, which have a range of about 100 meters. In addition, laser lights don’t emit heat and propagate through special lenses that project the light almost in a straight line.
This light projection, together with a system of cameras and sensors, makes the vehicle adapt the light beam to driving and road conditions without relying on the driver.

Headlight Types on Older Vehicles (5-15 Years)
Xenon. This type of headlight is also known as HID, an acronym that comes from the concept of high-intensity discharge. HID xenon lamps do not have a filament. Instead, the light is created by an electrical discharge between two electrodes in a small, airtight quartz capsule filled with xenon gas, mercury, and metal halide salts.
This improves durability on the road, as vibrations can cause damage to the filaments of lighting technologies. In addition, xenon headlights have a color temperature of 4000K-6000K, a bright blue-white light similar to natural daylight. On the other hand, halogen headlights have a color temperature of 3200-5000K, which is a warmer, yellowish-white light.
The light output increase of 35-watt HID xenon lamps is approximately 80% more light than a 55-watt halogen bulb. As a result, the HID Xenon system also consumes less power from your vehicle’s electrical system.

Halogen. These are the most common headlights in legacy and classic vehicles. These lights work similarly to the light bulbs in your house. Light travels through a thin wire filament, and the bulb is filled with halogen gas to make it burn brightly. More expensive halogen bulbs will shine brighter while emitting a whiter colored light, which helps to improve visibility.
This headlight is very popular because it has a light power three times higher than halogen lights. They also allow a greater range and a clearer vision for the driver, in addition to their useful life, which can reach 2,500 hours.
Contrary to what many of us might think, likely, headlight technology in cars doesn’t need to evolve any further. It will no longer be the human eye that will have to see where to go but an electronic brain that will not need to illuminate objects. It will be enough to detect them with any other technology.

Common Risks of Machine Learning
28 Oct 2021
In order to cater to the demand for complex interconnected systems, Machine Learning (ML) systems have evolved from traditional IT systems, which are typically simple programmes that handle simple datasets. ML systems create more opportunity by enabling organisations to process more complex use cases which are typically done by humans.
FEATURES OF ML SYSTEMS
MITIGATING THE RISKS OF USING ML SYSTEMS
The table below describes key risk areas of using ML systems and possible mitigation measures to reduce associated residual risks.
KEY CYBERSECURITY FACTORS AND APPROACHES
ML systems process and distil massive amounts of data, reinforcing the need for fundamental cybersecurity measures to protect data confidentiality and integrity, as well as to maintain the availability of ML services. Organisations may consider the following key factors and cybersecurity approaches:


I finally got my electric brake working for dual voltage. Here's a quick pic (click for larger version):
Left to right you see:
1) The main switch that sends voltage to the motor (two red leads) or the brake circuit (the long black cord wrapping around with black/white/green protruding)
2) The switch inside the brake circuit (120V) that makes sure 240V doesn't make it into the brake. The voltage coming into the circuit acts as both the "control" and the "controlled" current.
3) (on the left of the large white relay) a smaller relay that isolates the circuit from the voltage flowing to the motor
4) The "On Delay, Off Delay" relay (Macromatic TR-66122)
5) The rectifier
6) The transformer
What does it do? Basically, when the main switch is in the "Off" position 120V of AC are turned into 24V of DC and sent to the motor, stopping a 10" blade in about 6 seconds.
It works perfectly.
Parts were about $110 (The large relay is a $65 part). I'm sure it can be done cheaper but God knows I am no EE and this thing works like a champ.
I'll post more (proper diagram) later when I get more time.
