7 Tips to Pass GTU Exams Easily

1.Understand the Blueprint of the paper
This step is very important. By looking at the past year’s papers, you get an idea of what the paper will be like. You get the idea of how various questions’ marks are weighed. Buy a GTU question paper collection and start going through it. Based on your evaluation, you can utilize your time to prepare the questions which have more marks. I know a friend, who sits for hours, researching past years’ papers. He only prepares a handful of questions. He manages to pass each exam but doesn’t score high. He just studies for 1-2 day but still manages to pass!

2.Good diagrams
Even if you have difficulty in memorizing theory part, diagrams and figures (not female figures!) are easy to remember. So if you don’t have time or are too lazy to learn a theory part, remember its figure. If that question is asked in the paper, draw that figure as sexily as you can with pencil. Then write down whatever you vaguely remember about the theory. Highlight the technical terms too! Dude, this is GTU, you have to get smart to survive!

3.Good writing
I still remember how I wrote my ES (Environmental Science) exam. I knew no shit about the subject. But I wrote my own home made answers and wrote them in good handwriting and drew good diagrams and figures whenever necessary. And guess what? I passed in that exam!

4.Always refer last year’s question paper
Make it a habit to refer as many past question papers as possible before exams. By doing so, you get to know the importance of some questions. These questions are almost asked in every exam! So prepare such very important questions well. Sometimes such questions alone get you the passing marks. If possible, buy the GTU question paper collections.

5.Learn English
This tip is for my Gujarati medium friends. Without knowing English, it is difficult to understand the basic concepts of all subjects of engineering. Even if you understand the concept, you are unable to express it during exams. Many students fail in GTU exams only due to poor English. By learning English you can understand subjects better and you may also write your own ‘home-made’ answers convincingly.

6.Don’t always mug up chapters and lessons

In case of some subjects, like Environmental Science, mugging answers up is acceptable to an extent. But GTU students must try to avoid mugging up stuff. It is a tiresome process. Also, chances of forgetting the mugged up stuff during the exam is also high!  

Instead of just memorizing stuff, why not try to understand the meaning and concept behind it? Doing so is much more beneficial! By understanding the meaning and basics of certain portion, it will be etched in the mind for longer period of time. It can be recollected easily too! Pay attention in the class, try to understand how things work, read and understand more about the fundamentals and there will be no need of mugging things up!

7.Pay special attention to Credit subjects

This is a new update, which a reader provided me. According to him, GTU has this habit of coming up with totally unexpected and out of syllabus questions in case of credit subjects. Yes, this could pose a problem to students who are not well prepared. Keeping this in mind, why not give little bit special attention to credit carrying subjects?

Delve a bit deeper into the fundamentals of such subjects. If the basics are clear, no matter from where the question comes, one will be able to solve it! Usually out of syllabus questions are nothing, but a bit twisted and turned version of facts and figures from the syllabus. Those who know the minutest of details and fundamentals will be able to work things out and find the solution. So, in case of credit subjects, don’t just expect questions only from syllabus. Expect some tough questions and be prepared for them by focusing on the basics and minute details!

Now, after giving all that tips to pass GTU exams, the main thing is that there is no substitute for hard-work. If you have your own tips and tricks that you want to share, please use the comment section.

Nokia WILL Return in 2017 With Two New Android Phones

Nokia C1

According to the information handed to NPU, the Nokia C1 may come in two different size variants which will broadly share a spec sheet, but will have different camera tech, RAM, and onboard storage. 

The display size is quoted at either 5.5in or 5in both with Full HD resolution. The 5in model will have 2GB of RAM with 32GB of storage space and an 8MP camera, while the larger 5.5in has 3GB RAM, a 13MP camera and 64GB onboard storage. Both will feature 5MP front-facing secondary cameras.

As for the software, it's going to be Android-based, although we'd expect it won't get away clean and will likely have Nokia UI stuff put on top. There's also going to be Windows 10 variants in select markets, allegedly.

Major Nokia D1C Specs & Details

December 1 sees quite a treat for us; a major leak concerning Nokia's forthcoming Android handsets, including the D1C model. The info comes via NPU, which reports there will be two D1C variants, one will be a lower-tier 5in variant with the following specs:

• 5in 1080p resolution display
• Qualcomm Snapdragon 430 1.4GHz octa-core processor
• Adreno 505 GPU
• 2GB of RAM
• 16GB onboard storage
• 13MP primary camera
• 8MP front-facing camera
• Android 7.0 Nougat

The second variant will have similar specs with a few changes, including the display size (but not resolution), camera sensor and RAM:

• 5.5in 1080p resolution display
• Qualcomm Snapdragon 430 1.4GHz octa-core processor
• Adreno 505 GPU
• 3GB of RAM
• 16GB onboard storage
• 16MP primary camera
• 8MP front-facing camera
• Android 7.0 Nougat

The report alleges that both handsets are in the prototype testing phase, and the following renders are claimed to show more or less what at least one of the devices will look like.

There are, at present, no details about release date or pricing - though MWC 2016 in February is expected - and the major missing spec is the battery, of course.

Design Engineering ( DE ) - Canvas Format Details

Hello Everyone..,

 GTU introduced four elements in Design Engineering as below

1) Learning Need Matrix

2) Product Development Canvas

3) "AEIOU " Framework

4) Working Model

This canvases are developed by Prof. PARTH  PAREKH to familiar with this canvas.
Brief intro to ,

1) Learning Need Matrix :-
you have to work along with this canvas upto your last year.Firstly you have to define your topic on "PURPOSE/PRODUCT CONCEPT" as shown in below canvas.you have to fill up canvas using sticky notes.If you are  working on this canvas during 2nd year then you have to stick notes on "During BE II " properly  and vice versa.

2)  Product Development Canvas :-

In this canvas you have to stick notes appropriate with subheading.

3) "AEIOU" Framework :-

 A - Activities  

A- activities as the name suggests you have to describe all the activities you observed like if you are on signal crossing then you watched people,traffic police,trees,footpath,etc and the elements/note of that are stop vehicle,running vehicle etc by means of you have to describe some special notes on whatever you observed.

 E -  Environment 

 For Environment ... how's the environment during your observation. . Like warm, cloudy, soundly atmosphere, etc. ... and in element box you have to describe elements you observed like mobile, vehicle, etc.. you have to sketch floor plan and describe scene like a young man calling her friend.

 I -   Interactions

For Interaction as tittle tell you have to describe your interactions along people you observed.

O -  Objects

You have to describe observed object and user to correspondingly object frame and user framework.

U -  Users

NOTE: You have to fill out below canvas with sticky notes.

4) Working Model :-

If you are in 2nd year than you just have to make DEMO MODEL using thermocol and clay.And in last year you have to represent your working model.

New Technlology from 2015 to 2021

2015

The world’s first zero-carbon, sustainable city in the form of Masdar City will be initially completed just outside of Abu Dhabi. The city will derive power solely from solar and other renewable resources, offer homes to more than 50,000 people.

Personal 3D Printing is currently reserved for those with extremely large bank accounts or equally large understandings about 3D printing; but by 2015, printing in three dimensions (essentially personal manufacturing) will become a common practice in the household and in schools. Current affordable solutions include do-it-yourself kits like Makerbot, but in four years it should look more like a compact version of the uPrint. Eventually, this technology could lead to technologies such as nanofabricators and matter replicators — but not for at least a few decades.

2016

Space tourism will hit the mainstream. Well, sorta. Right now it costs around $20-30 million to blast off and chill at the International Space Station, or $200,000 for a sub-orbital spaceflight from Virgin Galactic. But the market is growing faster than most realize: within five years, companies like Space Island,Galactic Suite, and Orbital Technologies may realize their company missions, with space tourism packages ranging from $10,000 up-and-backs to $1 million five-night stays in an orbiting hotel suite.

The sunscreen pill will hit the market, protecting the skin as well as the eyes from UV rays. By reverse-engineering the way coral reefs shield themselves from the sun, scientists are very optimistic about the possibility, much to the dismay of sunscreen producers everywhere.

A Woolly Mammoth will be reborn among other now-extinct animals in 2016, assuming all goes according to the current plans of Japan’s Riken Center for Developmental Biology. If they can pull it off, expect long lines at Animal Kingdom.

2017

Portable laser pens that can seal wounds – Imagine you’re hiking fifty miles from the nearest human, and you slip, busting your knee wide open, gushing blood. Today, you might stand a chance of some serious blood loss — but in less than a decade you might be carrying a portable laser pen capable of sealing you back up Wolverine-style.

2018

Light Peak technology, a method of super-high-data-transfer, will enable more than 100 Gigabytes per second — and eventually whole terabytes per second — within everyday consumer electronics. This enables the copying of entire hard drives in a matter of seconds, although by this time the standard hard drive is probably well over 2TB.

Insect-sized robot spies aren’t far off from becoming a reality, with the military currently hard at work to bring Mission Impossible-sized tech to the espionage playground. Secret weapon: immune to bug spray.

2019

The average PC has the power of the human brain. According to Ray Kurzweil, who has a better grip on the future than probably anyone else, the Law of Accelerating Returns will usher in an exponentially greater amount of computing power than ever before.

Web 3.0 – What will it look like? Is it already here? It’s always difficult to tell just where we stand in terms of technological chronology. But if we assume that Web 1.0 was based only upon hyperlinks, and Web 2.0 is based on the social, person-to-person sharing of links, then Web 3.0 uses a combination of socially-sourced information, curated by a highly refined, personalizable algorithm (“they” call it the Semantic Web). We’re already in the midst of it, but it’s still far from its full potential.

Energy from a fusion reactor has always seemed just out of reach. It’s essentially the process of producing infinite energy from a tiny amount of resources, but it requires a machine that can contain a reaction that occurs at over 125,000,000 degrees. However, right now in southern France, the fusion reactor of the future is being built to power up by 2019, with estimates of full-scale fusion power available by 2030.

2020

Crash-proof cars have been promised by Volvo, to be made possible by using radar, sonar, and driver alert systems. Considering automobile crashes kill over30,000 people in the U.S. per year, this is definitely a welcome technology.

2021

So, what should we expect in 2021? Well, 10 years ago, what did you expect to see now? Did you expect the word “Friend” to become a verb? Did you expect your twelve-year-old brother to stay up texting until 2am? Did you expect 140-character messaging systems enabling widespread revolutions against decades-old dictatorial regimes?

The next 10 years will be an era of unprecedented connectivity; this much we know. It will build upon the social networks, both real and virtual, that we’ve all played a role in constructing, bringing ideas together that would have otherwise remained distant, unknown strangers. Without twitter and a steady drip of mainstream media, would we have ever so strongly felt the presence of the Arab Spring? What laughs, gasps, or loves, however fleeting, would have been lost if not for Chat roulette? Keeping in mind that as our connections grow wider and more intimate, so too will the frequency of our contentedness, and as such, your own understanding of just what kinds of relationships are possible will be stretched and revolutionized as much as any piece of hardware.

Truly, the biggest changes we’ll face will not come in the form of any visible technology; the changes that matter most, as they always have, will occur in those places we know best but can never quite see: our own hearts and minds.
