Microsoft Student Partner (MSP) -- key to successful career

MSP (Microsoft  Student Partner) 2014

No doubt MSP program is life long experience and most valuable gift from Microsoft to students.

I am very glad that MSP ( Microsoft Student Partner) program has got continuity this year too. J

MSP program is a program for IT enthusiastic who always wish to serve their society through sharing knowledge on technologies and who love to live with Microsoft technologies. So, i request everyone of those kind to not to miss this chance because this program is for the people like you. All The Best for all the applicant.

This is time to fulfill our dream by getting MSP title for our college or to work as bridge between MIC & college. MSP title itself is recognized worldwide. Lots of opportunities will arises after holding MSP title and you'll learn to building carrier, innovate new ideas, socialize yourself, partnering with other innovators,  specialize with your knowledge domain and moreover how to deal with peoples….these all possible when technology becomes absolute passion.

Yammer-The First and Most Powerful Enterprise Social Network

The First and Most Powerful Enterprise Social Network

Yammer brings the power of social networking to the companies. Yammer is as easy to use as great consumer software like Facebook and Twitter, but is designed for company collaboration, file sharing, knowledge exchange and team efficiency.

Social media has dramatically changed the way we share and connect with friends and family, and it will have an even more profound impact on the way companies operate. Giving your organization the advantage of a social foundation is critical for success in today’s fast-paced environment.

Yammer is a secure, private social network for your company. Yammer empowers employees to be more productive and successful by enabling them to collaborate easily, make smarter decisions faster, and self-organize into teams to take on any business challenge. It is a new way of working that naturally drives business alignment and agility, reduces cycle times, engages employees and improves relationships with customers and partners.

 It originally launched as an enterprise micro blogging service and now has applications on several different operating systems and devices.  Access to a Yammer network is determined by a user's Internet domain, so only those with appropriate email addresses may join their respective networks.

In February 2010, the company launched "communities", which are networks for which access is not restricted by domain, thus allowing businesses to connect to groups such as customers, partners, and suppliers. On June 25, 2012, Microsoft acquired Yammer for $1.2 billion..

Suggetions 

Windows 8

Update: Windows 8 is here and we have answers for you!

Windows 8 is now on all DreamSpark Premium Webstores! That means that you could qualify to get Window  for free!

If you haven't already done so, click here to search for your school and see if you qualify to get Windows 8 for free!

To help you out, here are some frequently arises questions that we have been getting before.

1) How do I obtain a DreamSpark Premium account?

Contact your program administrators for your respective school/ departments for details on how to obtain a DreamSpark Premium account. Your school/department must already have a DreamSpark WebStore. 


2) I am unable to download Windows 8 as I have downloaded the Preview. How can I get the final version?

If you are unable to download because you previously downloaded Consumer Preview, please log out of your DreamSpark account and log back in. This should solve the issue. 

3) What about languages?

Windows 8 comes in multiple languages, but this depends on each store. If you don't see a language, ask your program administrator.

4) Which versions are available on DreamSpark?

Both the 32- and 64-bit version are available.

5.) Is this the real deal? 

Yes, it's the final version!

Low Power Design

Due to power scarcity, necessary to preferred Low Power Design techniques. Energy conservation refers to reducing energy through using less of an energy service. Energy conservation differs from efficient energy use, which refers to using less energy for a constant service. For example, driving less is an example of energy conservation. Driving the same amount with a higher mileage vehicle is an example of energy efficiency. Energy conservation and efficiency are both energy reduction techniques.

Low Power electronics are electronics that have been designed to use less electric power, e.g. notebook processors.

Some features of low power design are: portability, isolation, battery power, and low heat dissipation. Power is a function of frequency, load capacitance, and voltage: reduction in any of these will reduce the consumption of power by our system.( this really applies only to complementary metal oxide semiconductor [CMOS] components, the most prevalent in law power device, not to certain other logic families such as emitter –coupled logic[ ECL].

P= f C V²   

Where            P = power

                        f = frequency

                        C = load capacitance

                        V = DC supply voltage

Thanks to integrated circuit technology, electronic devices have greatly decreased in size and mass over the past few decades. Most of us routinely carry or wear electronics every day. The formula above is most convenient for low power design. While VLSI (Very Large Scale Integration) technology, particularly CMOS, has enjoyed the rapid exponential growth characterized by Moore’s Law, energy storage Technology (mainly batteries) has grown much more slowly.

Application Areas for Low-Power Electronics

Portable computing, communication, and multimedia devices

-         Laptops

-         Palmtops

-         Cell phones

-         Pagers

-         Video Recorders 

-         Cameras 

-         Watches (Power < 500nW @ 1.5V)

Remote sensing

-         Long-term environmental monitoring in wilderness areas or the ocean

-         Mobile robots

-         Satellites and space probes

Implantable biomedical devices

-         Pacemakers

-         Defibrillators

-         Muscle stimulators

-         Neuro prosthetic devices

Low power systems are usually smaller and cheaper to manufacture (smaller heat sinks, no cooling fans, smaller power supplies, smaller batteries).

Power Sources for Low-Power Devices

Batteries –  Most Common Power Source for Portable Electronics. Batteries convert chemical energy into electrical energy by means of a reduction-oxidation (redox) reaction.

Example: Alkaline cell operation.

 anode reaction (oxidation):        Zn + 2OH^{– ______} Zn(OH)₂ + 2e^–

 cathode reaction (reduction):     2MnO₂ + H₂O + 2e^{– ________} Mn₂O₃ + 2 OH^–

electrolyte:         KOH (K⁺, OH^– in solution)

          overall reaction: Zn + 2MnO₂ + H₂O ^_________Zn(OH)² + Mn₂O₃

Electron flow (i.e., current) external to the battery balances internal ionic flow.

Battery Types Grouped by Application

General consumer electronics ( portable audio equipment, toys, etc.)

-          Alkaline (Duracell, Energizer, etc.) – Standard AAA, AA, C, D, 9V cells

-          Zinc-Carbon (old technology, but cheap) – Standard AAA, AA, C, D, 9V cells

Film cameras and flash units

-         Alkaline

-         Lithium

Wristwatches

-         Silver – “Button” batteries

Hearing aids

-         Zinc-Air – “Button” or “coin” batteries

Smoke detectors

-         Mercury

-         Lithium

CMOS memory backup

-         Lithium

Medical implants (pacemakers, etc.)

-         Mercury – Used in implants before 1972

-         Zinc-Air – Used in many modern implants

-         Lithium-SVO (silver vanadium oxide) – Used in implantable defibrillators, where they can supply microamps for years and occasional amp-level pulses.

General guidelines for Low Power Design

-         Lower clock frequency

-         Lower supply voltage to digital logic

-         Shut down unused circuits

-         Put controller into sleep mode when not needed

-         Terminates all unused inputs. Don’t allow any to float.

-         Avoid slow signal transition

-         Make normal states use the lowest current etc.
