Kepler Spacecraft in Emergency Mode

Kepler Entered Mode on April 6

According to an update of April 8 from Charlie Sobeck, mission manager at NASA’s Ames Research Centre in Moffett Field, California, Kepler seemingly entered the mode on April 6. Kepler had burnt more of its dropping supplyof fuel in an emergency mode, which is essential to ignite its thrusters and position the spacecraft in communicating with Earth.

The turning manoeuvre which would have begun the new planet hunt had not yet been executed by the spacecraft. Kepler, till now had discovered planets by observing the slight dimming of starlight triggered by an orbiting planet that passed in front of a star. The investigation has been enthusiastically successful, discovering over 1,040 confirmed planets as well as more than 4,700 planet candidates since the launch of 2009.

The new campaign is said to have run from April 7 to July 1 and it would have looked out for the temporary brightening of star due to a different effect known as gravitational microlensing. The gravity of an intervening object, in microlensing, like in the case of planet, tends to focus and intensify the light from a background star, causing it to brighten.

Microlensing Targets Big Planets at Great Distances

Contrasting to Kepler’s other discoveries that seem to be smaller planets comparatively close to their host stars, microlensing tends to target big planets at great distances from their stars or even lonely planets seem to bewandering on their own through the depth of space. Ground-based telescopes have revealed 46 planets through microlensing and the astronomers expect that Kepler would discover 10 or more during the campaign.

 These kinds of discoveries would be helpful in narrowing the statistics on how common free-floating planets could be throughout the Galaxy. Astronomers have synchronized an intricate plan wherein around two dozen ground-based telescopes that have been spread across six continents, would be gazing at the same area of the sky at the same time as Kepler.

 They comprise the Optical Gravitational Lensing Experiment – OGLE survey that tends to hunt for microlensing events from the Las Campanas Observatory, in Chile. OGLE intended to shift its observing strategy slightly to overlap with the same fields which Kepler had been looking at. NASA’s Spitzer Space Telescope was to have joined in the hunt too, in late June.

Kepler’s Microlensing Campaign Presently on Hold

It could have been the first microlensing survey directed at the same time from the ground as well as from space. The different vantage points could have enabled astronomers to research the potential microlensing planets much more easily than just utilising one or two ground-based telescopes. Andrew Cole, astronomer at the University of Tasmania in Hobart, Australia had stated that `there is a strong feeling like it’s Christmas morning and we were all set to unwrap a shiny new toy and then we had to put everything on hold owing to power outage or something’.

His team had scheduled to use a 1.3-metre telescope in Tasmania in order to track on microlensing alerts from Kepler. The start of Kepler’s microlensing campaign presently is on hold till engineers tend to get the telescope working again. It is presently about 120 million kilometres from Earth, which means that each message tends to take 13 minutes to reach Kepler and back. Days that are lost from the microlensing campaign would be difficult to make up later.

 NASA’s director of astrophysics, Paul Hertz, had touted that the Kepler microlensing survey is a step towards the next big space telescope of the agency, the Wide-Field Infrared Survey Telescope, that is intended to do microlensing searches after it launches in 2020.

MIT's new Chronos System Promises Precise Wi-Fi Tracking

Chronos – Wireless Localization Technology

Several users tend to use Wi-Fi to browse social media, check emails and watch videos. However according to Dan Misener, Radio technology columnist, researchers at MIT have invented something known as Chronos which is the latest way of using Wi-Fi in tracking the exact position down to the centimetre. Chronos is a `wireless localization’ technology or a Wi-Fi positioning system and is essentially a method of utilising Wi-Fi in figuring out where you are.

There are various means of doing this though Chronos tends to work by measuring the time it may take for a signal to travel from one wireless device to another device. For instance, if you have a smartphone and it is connected to a wireless router, the router tends to send information to the phone. The phone receives the same and then sends back a signal.

On measuring the time taken and by applying some calculation to the signal, one can determine where the smartphone is with regards to the router, the distance and the angle. In many ways, it tends to be the same way how radar or sonar systems seem to work. Chronos could be considered as a way to turn a regular Wi-Fi router into a kind of radar system which can distinguish objects and where they could be in the world.

Difference is Accuracy

The big difference is the accuracy. Customers-grade GPS tend to pinpoint you within a few metres distance but Chronos system tends to locate you within tens of centimetres. Moreover there are instances where GPS sometimes does not function at all like in underground or when one is indoors. Chronos tends to work anywhere within a Wi-Fi router range.

There are various other Wi-Fi based location system and are often utilised in airports, hotels and shopping mall to track foot traffic. U.S. malls tend to use shopper’s cell phones to track them, but those systems need several access point and many routers to cover a large area and triangulate the location of someone.

The distinctive thing regarding Chronos is that it only needs a single access point, a single router and one can set this up at home or a small business without incurring much expense.

Utilised in Locating Lost Device within the Home

The researchers have also informed that Chronos tends to be 20 times more accurate than the prevailing systems. One reason for using it in home is `home automation’ wherein there is a rise of the smart homes which tends to respond to who is in them.

Hence knowing who is at home and where people are within a home could be useful information. In a demonstration, the researchers had shown how Chronos tends to accurately identify which room a person was in 94% of the time. This device could also be utilised in locating a lost device within the home which could be helpful whenever a phone or a tablet would be misplaced.

Chronos can be used in controlling who gets to access the Wi-Fi, which could be useful for small businesses. Deepak Vasisht, one of the MIT researchers had informed at last month’s symposium, that if one walks into a Starbucks, they tend to get free Wi-Fi, but if one talks to them, they inform that they are very much keen in restricting free Wi-Fi access only to their customers and do not want to give free Wi-Fi to their neighbours which could end up causing congestion for their own customers. Hence a coffee shop could use Chronos to cut off Wi-Fi freeloaders.

Ford's Autonomous Fusion can see in the Dark Without Headlights

Ford Fusion Hybrid Autonomous Research Vehicle – No Headlight On

There are a lot of talks going on regarding the present status of self-driving cars. Ford is aware that its systems are not perfect yet; however its self-driving Fusion research vehicle seems to be getting better and is capable of navigating in the dark. Ford Fusion Hybrid autonomous research vehicle with no headlights on, had recently navigated along lonely desert roads to perform task which would be dangerous for a human driver. Driving in pitch black at Ford Arizona Proving Grounds symbolises the next step on the journey of the company in delivering fully autonomous vehicles to consumers all over the world.

Its car have the potential of tackling the dark of night owing to two technologies namely 3D mapping and LiDar which tends to stand for Light Detection And Ranging, uses lasers for measuring the distance to objects. The 3D maps tend to provide extra information regarding the road, comprising of markings as well as the geography. The LiDar also helps the car to recognize where on the map it is at that point of time. Utilising infrared improving goggles, the engineers of Ford were able to observe the car work its magic as it casts infrared laser beams around the vehicle.

Adequately Strong to Steer Impeccably

Presently, the night-time, lights-off testing has been limited to its Arizona proving grounds, since it is quite illegal in operating vehicle on public roads at night minus the traditional illumination. Though autonomous night vision could be helpful for vehicles to continue to move towards a destination if infrastructure or the own lighting of the vehicle tends to goes dark, dashing forward in pitch black could be a bit scary to an average driver or passenger.

Moreover, it would also put a dent in the light pollution which covers most of the sky in areas with great population density.It is an important progress which shows that even without cameras that depends on light; Ford LiDar tends to work with the virtual driver software of the car and is adequately strong to steer impeccably around winding roads. Though it is idyllic to have all the three modes of sensors namely radar, cameras and LiDar, the last can operate independently on roads without stoplights.

No Driver to Intervene/Control Vehicle

Jim McBride, technical leader for autonomous cars says that due to LiDar, the test cars are not dependent on the sun shining, or cameras detecting painted white lines on the tarmac. In fact LiDar enables autonomous cars to drive well in the dark as they do in the light of day’. After over a decade of Ford autonomous vehicle research, the company has been dedicated to achieving fully autonomous driving possibility that as defined by SAE International Level 4 does not need the driver to intervene and control the vehicle.

Ford, this year will be increasing its autonomous vehicle test fleet bringing the number to around 30 self-driving Fusion Hybrid sedans for the purpose of testing on roads in California, Arizona and Michigan. These elements seems to be the main elements of Fort Smart Mobility, the plan in taking Ford to the next level with regards to connectivity, mobility, customer experience, autonomous vehicles, together with data and analytics.

Time Management Techniques to Increase Your Productivity

Whenever missing deadlines, being late in appointments, and feeling drained without tangible accomplishments are common occurrences in your work life then you have to admit that there is a big problem. Fortunately, this problem is not big enough that good time management techniques cannot handle.

What are time management techniques that will ensure productivity? 

Once you start practicing the following time management techniques you can see for yourself how productive your work day would be:

• Be realistic on your “to-do” list – there are people who have a daily to-do list that is so long you will wonder if the items could be accomplished in a month! Do not be this person. Try to come up with a “processed” to-do list. This means that you have already gone through all the tasks you need to accomplish and you are now going to prioritize the items on the list based on their necessity and value. In other words, your to-do list for the day should only contain tasks that you have to accomplish during that day (necessity) and those that will help you advance your career (value). Four items would suffice since in reality you only have about five hours in a day to actually spend working. If you are not able to finish everything on your list, move the unfinished items on the next day and complete the five tasks again. 
• Avoid tasks that waste your time – if you are in a habit of glancing at your Facebook or other social media accounts every now and then, stop it. If your colleagues are always dropping by to chat, close your door (if you have your own room) or say politely that you have to urgent work to finish. Every time you get interrupted at work, you have to spend extra time trying to get back to the “work mode” you initially have. 
• Have one complete organizer or personal calendar – time management techniques will do you no good if you have no clue what are the things that you need to do given the time that you have. There individuals who maintain different calendars for different aspects of their lives. For example, they have a calendar for their social activities, for their work appointments, and another for personal engagements. This system does not work. The only way you can manage your time wisely is by organizing every little thing that you do in a day. By maintain one organizer/ personal calendar for everything you can readily see, at a glance, if you still have any more available time for other things. 
• Set specific time to finish every task – if you have a specific time deadline in mind your brain and whole body will work with urgency. That is why you need to put time limit on every task and you force yourself to stick with it. You should only adjust these time frames when absolutely necessary like your boss called for an emergency meeting.

Proper observance and application of the above mentioned time management techniques will undoubtedly make your work day more productive. But aside from that, it will also relieve you of stress and tension since you know that you are not helpless but fully in control of your day.
