India At Mars.. MOM

This is really a proud moment for me and also for every single #Indian as we are now among the very few players of technology who have reached mars “The Red planet” .No words can describe this feeling I am feeling proud on our ISRO scientists and all the associated members with this mission. Heartily congratulations to our countrymen for this milestone.

This is India’s first and worlds cheapest mars orbiter mission which is totally succeeded to reach the mars orbit in its very first attempt on 24 September 2014 2:00 UTC 06:27 AMT .The orbiter was launched from Satish Dhawan Space Center SHAR, Sriharikota at 09:08 UTC (14:38 IST) on 5 November 2013 by the Indian Space Research Organisation (ISRO) using a Polar Satellite Launch Vehicle (PSLV) rocket C25.

Mars Orbiter Mission is India’s first interplanetary mission to planet Mars with an orbiter craft designed to orbit Mars in an elliptical orbit. The Mission is primarily technological mission considering the critical mission operations and stringent requirements on propulsion and other bus systems of spacecraft.

Mars Orbiter Mission carries five scientific payloads to observe Martian surface, atmosphere and exosphere extending up to 80,000 km for a detailed understanding of the evolution of that planet, especially the related geologic and the possible biogenic processes on that interesting planet. These payloads consist of a camera, two spectrometers, a radiometer and a photometer. Together, they have a weight of about 15 kg.

Objectives Of MOM:

Following are the major objectives of the mission:

A. Technological Objectives:

2015 ASTON MARTIN V12 VANTAGE S DEBUTS

OVERVIEW OF ALL NEW 2015  V12 VANTAGE S :

“The new car replaces the outgoing V12 Vantage in markets around the world and, with the exception of the One-77 hypercar, arrives as the fastest road-going Aston Martin yet offered,” said Aston Martin in a press statement.

The 2015 model will be equipped with a brand-new 565-hp 6.0-liter V12 engine and comes with a seven-speed Sportshift III automated manual transmission. The company promises that the unit is “lighter” than a base six-speed manual gearbox according to a company press release.The Vantage gas a top speed of 205 mph, and also comes equipped with a lighter exhaust system modeled off of the One-77.Other features include the debut of three-stage adaptive damping which allows drivers to choose between Normal, Sport, and Track modes according to Aston Martin.
A new lightweight forged alloy 10-spoke wheels and a black painted roof are also standard.

TECHNICAL SPECS :

POWER   -573PS

TORQUE-620Nm

SPEED    -205mph

  • ENGINE: THE NEW AM28 ENGINE

The new-generation AM28 V12 engine delivers exceptional performance. Integrated with our ‘Gen4’ VH architecture this combination drives peak power to 565bhp and a phenomenal top speed of 205mph. An advanced engine management system controls AM28 alongside the debut of Dual Variable Camshaft Timing and knock-sensing – all improving efficiency and engine capability.

  • GEARBOX: INTRODUCING SPORTSHIFT III

To unleash the full capability of AM28 we’ve produced ‘Sportshift III’ – an all-new gearbox unique to V12 Vantage S. Sportshift III produces new levels of precision and a level of driver engagement you would expect from our most aggressive sporting experience. With a twin-plate clutch and slave cylinder taken from the One-77 hypercar, V12 Vantage S has a transmission developed for peak performance.

  • TRANSMISSION CONTROL: ENGINEERED FOR SPEED & CONTROL

As a rear mid-mounted unit, Sportshift III contributes to a near-perfect 48:52 weight distribution. Paddle-shift controls, tipped with leather or carbon-fibre link to advanced electro-hydraulic controls meaning each gear-shift takes less than 70 milliseconds. Combined with a drive ratio of 3.727:1 and seven-gears – enabling the first six gears to sit closer – the V12 Vantage S has incredible standing start and in-gear acceleration.

  • EXHAUST: SOUNDS INCREDIBLE

Every Aston Martin sounds unique, V12 Vantage S introduces a new voice to the choir. Using the same reduced size and lightweight muffler as Vanquish & One-77 our engineers set out to create the perfect sound for our most aggressive car. A ‘savage rasp’ is the result of high-frequency tones matched with a powerful rumble, but progression is linear as balanced cross pipework mixes exhaust from each bank. Clear growth at high-revs rewards you for pushing V12 Vantage S to the limit.

  • ADAPTIVE DAMPING: UNRIVALED AGILITY

Adaptive damping developed for Vanquish is introduced to V12 Vantage S. Three modes; normal, sport and track give fantastic driver flexibility, changing ride firmness and the sharpness of handling. Hundreds of readings per second adjust each damper based on road conditions, vehicle performance and driver control. Integrating this technology within our smallest sports car chassis saw innovative new suspension mounts engineered specifically to mate the Vantage body with this advanced ADS.

  • DYNAMIC STABILITY CONTROL: PERFECT FOR THE SKILLED DRIVER

Introduced on V12 Vantage, V12 Vantage S sees a complete recalibration of both traction and stability controls for complete control of the increased power and adaptive damping. Traction control automatically senses front / rear wheel rotations, adjusting engine torque or braking instantly. Stability control senses over or under-steer and applies the relevant brake level. Technology designed to complement the handling experience and improve control for the skilled driver.

  • BREAKS: CARBON CERAMIC BRAKES

3rd generation brakes, the best we’ve ever developed. Working with specialist suppliers we created a revised disc coating and the largest braking surface ever used on an Aston Martin. Cross-drilled carbon ceramic matrix reduces weight, noise and judder – all with virtually no brake fade. Specially designed to dissipate heat, braking performance is prolonged, especially in dynamic road or track conditions. Calipers uniquely supplied for Aston Martin feature a strengthened bridge and monobloc construction.

  • WHEELS & TYRE: LIGHTWEIGHT WHEELS

An all new lightweight forged wheel creates a striking side profile as more of the brake caliper and carbon ceramic disc are displayed. Over 1kg lighter than the standard V12 Vantage wheel, the reduced unsprung mass provides better turning response. With all this technology, we don’t forget the one element in contact with the road – tyres. Pirelli P Zero Corsa tyres come as standard for superb grip and handling with improved all-weather performance from the Pirelli P Zero as a no cost extra.

Near Field Communication(future of electronic devices)

We all are familiar with most common types of communication offered by electronic devices like cellphones which include bluetooth and wifi,both the technologies works on radio to transfer information back and forth the device within some specific range say 10 meters but near field communication ,abbreviated NFC,is a form of contactless communication between devices like cellphones and tablets for faster and convenient way of communication between devices.NFC uses electromagnetic radio fields to communicate with the other device within a close proximity say 2-4 inches ,Contactless communication allows a user to wave the smartphone over a NFC compatible device to send information. It doesn’t require much steps for setting communication.

NFC requires less power than bluetooth and wifi,it doesn’t requires any pairing with the other device like in bluetooth so the connection becomes fast. 

 

Samsung’s Galaxy Camera Is The Camera Of The Future [Review] Popsci

By Dan Bracaglia and Dan Nosowitz

Dan Nosowitz: I wasn’t optimistic about the Samsung Galaxy Camera. The idea of a camera with a big touchscreen and a full version of Android, complete with 4G LTE connection, is enticing, but I do not care much at all for Samsung’s other Galaxy products, which to this point have just been smartphones and tablets. I find their hardware chintzy and their software difficult and confused, as the company insists on mucking up Android (which is really great!) with their slow and bloated skins. Yet to my surprise, the Galaxy Camera is by far my favorite product in the Galaxy line.

As an Android device, it’s got pretty much the same guts as a modern Galaxy smartphone. That means a huge 4.8-inch screen, a quad-core processor, a Samsung-ified version of Android 4.1 Jelly Bean, and 4G LTE connectivity. It even has a microphone, intended to be used while taking video, so theoretically you could ditch your phone, make calls with a VoIP service or Google Voice, and use this as your exclusive camera/phone. And of course it has access to the entire Android app store, which has fairly recently been renamed Google Play. But this is not a Galaxy smartphone with an improved camera; this is a high-end Samsung point-and-shoot with Android.

Image
Using the Galaxy: Performance is pretty good; it’s not as fast getting around as the screamingly-fast Nexus 4, but it’s certainly not laggy. Android 4.1 is very nice; the Galaxy Camera has all the benefits of Google Now and all kinds of other great Android stuff. The screen is not the best screen I’ve ever used (not quite as sharp as the iPhone 5 or Nokia Lumia 920), but it is a very good screen, and it is definitely the best screen I’ve ever used on a camera. I think 4.8 inches is too big for a phone, but man is it awesome on a camera. You can actually share photos with a group on this thing!
Samsung’s software is, as always, annoying. It’s not as in-your-face with a million new gestures and pop-ups and buzzword-y features that plague its Galaxy S III and Galaxy Note smartphones. It’s not wildly different from stock Android but aside from the camera interface, there’s not a single thing I like better about the changes Samsung’s made. Even the soft buttons (Menu, Home, Back) work differently on this phone than on other Android devices. Why? And the keyboard I think is pretty poor (autocorrect is unhelpful, word recognition isn’t good), though it’s very easy to download a new keyboard from Google Play.

Image

It’s only a little awkward to use as an Android device; I’m not sure exactly how to hold it, as it’s thicker than a regular Android phone and also has the lens mount protruding. Dan Bracaglia’s solution left his finger sitting on the little door in from of the lens–not good, since that door is notorious on compact cameras for breaking or locking up, rendering the camera useless. But it’s not that hard, and I found it pretty capable for browsing Twitter or the web, checking email, and doing most other things you’d do on a smartphone. And that’s kind of an achievement in itself; this isn’t a skimped, shitty version of Android–it’s high-end, just like on a top-tier phone.

Image

I think the camera interface is great; the new stock camera app on Android is innovative and excellent in its own right, but it doesn’t offer as many manual controls, so I think Samsung’s camera app is a perfect solution for a more capable camera. For someone who’s not an expert photographer, I really loved how Samsung guides the user through the app. And everything is done on the touchscreen; the only buttons are a shutter, a zoom toggle, and a flash trigger. That’s great for novices who are much more comfortable with navigating menus on a smartphone than navigating the airplane-cockpit-like controls of a DSLR. Everything’s right out in the open: you don’t have to guess at what a switch means, because it’s spelled out on the screen.

The sharing options are easy and intuitive; when you look through photos, the top bar gives you sharing options, and it places your most recently used sharing option in its own little spot up there. For me, that means posting to Instagram is a one-tap affair, right from the camera app. Love it.

Image quality for me is kind of an interesting beast. It will take, without question, the best Instagram photos of any device that actually has Instagram on it. (Yes, I know you can take photos with a DSLR and post them to Instagram. But that’s not really what Instagram is about.) It’s no question that the Galaxy Camera takes better shots than any smartphone I’ve ever used.

Size: But the camera is too big. For me, a camera’s physical size is second only to image quality as the most important element, and then only barely second. The Galaxy Camera is not pocketable. (I do wear skinny-ish jeans, but I can’t imagine what kind of pockets could comfortably hold it.) I actually like the hardware design a lot; it’s all plastic, but, unlike Galaxy smartphones, doesn’t feel cheap at all. It feels really well-constructed, sturdily and simply designed without getting too basic. It’s one of the most attractive gadgets Samsung’s ever made, frankly, but I would much rather it had a slightly smaller screen in return for a smaller footprint. Dan Bracaglia noted that the weight also has the benefit of stabilizing the camera; light cameras can sometimes move around too much, and he thinks Samsung “nailed” the weight.

That size means I have the camera in my bag rather than my pocket. When I’m out and about and see something I want to shoot, it’s just faster and easier to snag my phone out of my pocket than fish around in my bag. And unlike a DSLR, which takes photos that are in a completely different league than my phone, the Galaxy Camera is merely “better” than my phone. I found myself not always bothering; if I can get a B- photo with my phone, who cares about a B+ photo from the Galaxy Camera? It’s not like I’m going for an A-level photo from my DSLR.

Price: And that brings us to the most salient point in this whole review: who is the Galaxy Camera for? Its image quality is not wildly improved from a nice $200 point-and-shoot, though it is certainly a superior product, thanks to its connectivity, interface, and bonus access to all of Android. At $500, the camera is right at the very top of the price pyramid for compacts; in fact, for that price, you could snag any of several very nice mirrorless interchangeable-lens cameras from Sony, Olympus, or Panasonic, or even a low-end DSLR like last year’s Nikon D3100. All of those cameras would thoroughly trounce the Galaxy Camera on image quality, but they’re also less capable in a lot of ways.

In Conclusion: What’s most interesting about the Galaxy Camera is how obvious it now is that this is what consumer cameras will look like in the future. A mirrorless camera with interchangeable lenses but with this kind of connectivity and interface? That would be amazing. It’s so much easier and faster to use for non-professionals than the more traditional camera control schemes, and the sharing options are the wave of the present and future. Of course you should be able to instantly upload photos to the cloud, to Facebook and Twitter and Instagram, to email them to your friends and family, to edit them in a mobile version of Photoshop. The Galaxy Camera isn’t quite right for most people, but it’s so close. Someone’s going to do this right, and soon, so let’s just consider the Galaxy Camera a sneak preview.

Raspberry Pi supercomputer with lego

The team, led by Professor Simon Cox, consisted of Richard Boardman, Andy Everett, Steven Johnston, Gereon Kaiping, Neil O’Brien, Mark Scott and Oz Parchment, along with Professor Cox’s son James Cox (aged 6) who provided specialist support on Lego and system testing. Professor Cox comments: “As soon as we were able to source sufficient Raspberry Pi computers we wanted to see if it was possible to link them together into a supercomputer. We installed and built all of the necessary software on the Pi starting from a standard Debian Wheezy system image and we have published a guide so you can build your own supercomputer.
Raspberri pi supercomputer

The racking was built using Lego with a design developed by Simon and James, who has also been testing the Raspberry Pi by programming it using free computer programming software Python and Scratch over the summer. The machine, named “Iridis-Pi” after the University’s Iridis supercomputer, runs off a single 13 Amp mains socket and uses MPI (Message Passing Interface) to communicate between nodes using Ethernet. The whole system cost under £2,500 (excluding switches) and has a total of 64 processors and 1Tb of memory (16Gb SD cards for each Raspberry Pi). Professor Cox uses the free plug-in ‘Python Tools for Visual Studio’ to develop code for the Raspberry Pi. Professor Cox adds: “The first test we ran – well obviously we calculated Pi on the Raspberry Pi using MPI, which is a well-known first test for any new supercomputer.” “The team wants to see this low-cost system as a starting point to inspire and enable students to apply high-performance computing and data handling to tackle complex engineering and scientific challenges as part of our on-going outreach activities.” James Cox (aged 6) says: “The Raspberry Pi is great fun and it is amazing that I can hold it in my hand and write computer programs or play games on it.”
