Technical Scavenging.. Something new?

Nah..!

We can take it as a combo pack of

"ENERGY HARVESTING + TECHNOLOGY"

Simple techniques in our daily life that can help in utilising the mass energy that we waste in our daily tasks.

Here we are introducing some of the common things that technology has modified to provide us with simple ways to keep ourselves update with the new era of sustainable energy consumption and development. Let us take a step ahead and at least get aware of some of the basic gadgets around us!....

 

BLINDED BY THE LIGHT ..

We all are well acquainted about the new emerging technologies and efforts going on to harvest the solar energy. One of them here we see is "Blinded By The Light"!.. We generally use blinds to cover up our windows and prevent our room from the scorching sun. What if we utilise the same scorching sun to produce some electricity for us? I hope our viewers might have got an idea of this article by now! The blinds used to cover our room can collectively be used to absorb solar energy of the sun in the day time and that energy can be easily converted into electricity by a simple solar cell to energise our electrical appliances like table lamps, small bulbs etc. Don't you think it's a nice way of sustainable energy consumption?!!

 

 DISCO-TECH

Well..Well..Well.. we are sure that this technology would surely grab your interest for a while.. It's quite funny and interesting to know that the more you enjoy the Disco Dancing, the more the Disco would enjoy your Dance! It's not that difficult to understand by the way. A new technology has emerged where springs are fitted under the Disco Dance floor and through your dance, the springs would join you in their to and fro motion which would then can be converted into electricity so much so that even the complete lighting system of the region can be powered by that vibrational energy!.. Isn't it interesting?

 

 ON-AND-OFF ROCKER

Who would not like to rock on a chair while reading or even while sleeping? Remember the old traditional chair that you might have been watching for so many years in your home? But have you ever imagined that the energy you use unknowingly while rocking on that chair can be used to lighten a lamp? Yeah! We are absolutely correct. This is a modern era classic invention of rocking chair where your rocking to and fro motion can generate energy that can be stored and then can further be utilised to power the overhead light that is already attached to this chair. So now rock-n-roll and save your electricity bills too!

SHAVE AND A KILOWATT

How now guys? Tired of shaving and want some electric shaving kit? We know that there are many available now in the market. But what if you get free from charging and discharging overheads of such shaving kits? To be more clear what if your shaving tool gets charged and discgarged at the same time while you are busy with your shave that too without consuming your household electricity? Hmm.. To be more clear, here's a shaving tool which works on the energy provided by the rolling of the wheels attached to blade. This rolling energy can be stored and can be used in re-winding of the wheels to automatically move on your face. Isn't it a nice technique to the way of sustainable energy consumption?

                             Lets get started with the basic programming in 'C'

                                                   1.Addition of two numbers.

#include<stdio.h>
#include<conio.h>
main()
{int a,b,c;
printf("Enter first number\n");
scanf("%d",&a);
printf("Enter second number\n");
scanf("%d",&b);
 c=a+b;
printf("Sum=%d",c);
getch();
                                                      }

2.Subtraction of two numbers

#include<stdio.h>
#include<conio.h>
main()
{int a,b,c;
printf("Enter first number\n");
scanf("%d",&a);
printf("Enter second number\n");
scanf("%d",&b);
 c=a-b;
printf("Difference=%d",c);
getch();
}

3. Multiplication of two numbers


#include<stdio.h>
#include<conio.h>
main()
{int a,b,c;
printf("Enter first number\n");
scanf("%d",&a);
printf("Enter second number\n");
scanf("%d",&b);
 c=a*b;
printf("Product=%d",c);
getch();
}

4.Divison of two numbers

#include<stdio.h>
#include<conio.h>
main()
{int a,b,c; float d;
printf("Enter first number\n");
scanf("%d",&a);
printf("Enter second number\n");
scanf("%d",&b);
d=a/b;
printf("Quotient=%d",d);
c=a%b;
printf("Remainder=%d",c);
getch();
}

Apple Vs Samsung!

·       US “AAA” rated company APPLE finally got the justice in Federal court in san Jose, California.

·        Samsung was found to have infringed upon 6 of 7 Apple patents, 21 samsung products face ban.

·        Scrolling (bounceback & rubber band effect), pinch-to-zoom & tap to zoom centering capability; distinguishing between single & multi-touch; one-fingered scrolling.

Actually what happened is that -In August 2010,  few months after Samsung launched its Galaxy smartphone, a team of Apple lawyers flew to South Korea(where Samsung is having its own store).

Apple's late co-founder, Steve Jobs, had already told Samsung executives at a meeting that he considered the Galaxy S, based on Google's Android operating system, an illegal copy of the iPhone. But Apple had given the extensive business ties between the two companies - Samsung is one of Apple's key component suppliers - a negotiated solution seemed most likely.

Now after extension is over Apple took this issue to Court. Point targeted against Samsung by apple -  Galaxy S, based on Google's Android operating system, an illegal copy of the iPhone.The case is ruled and found out that Apple iPhone’s front, back & home screen copied by Samsung, Apple violated two Samsung technology patents, while Samsung violated one Apple patent. It awarded small damages to both and banned both companies' infringing smartphones and tablet PCs, few of which are currently in stores in South Korea.

s        In future Galaxy S, Galaxy S||. Nexus S, Mesmerize, Vibrant, Nexus S smartphones, Galaxy Tab & Tab 10.1 may be banned in in US. But the good thing is that S3 not affected.

Finally, the jury awarded Apple $1.05 billion in damages, which could be tripled as the jury found Samsung acted willfully. Samsung could now face a costly ban on sales of key smartphone and tablet products.

Using torrent is not illegal. Sharing of copyright information is. Having said that, if you are a torrent user & are fed up of internet service provider (ISP) clamping down on torrent speeds or are wary about your privacy being compromised(because of over-zealous media industry watchdogs), you should consider services like www.peerblock.com & www.btguard.com. BTGuard, paid services completely hides your computer’s IP address & provides a secure, encrypted route for your torrent data.  Peerblock is open source and works in conjunction with www.iblocklist.com. It essentially block your computer’s communication with advertising or spyware oriented servers, computers monitoring torrents or computers which have been hacked (botnets).

Rain- proof your gadgets

ü  You must avoid talking on the phone while walking in the rains even with an umbrella. Or use the headphones while taking a call in the rain.

ü  Avoid keeping your phone in the pant pockets & keep them in your hand bags instead.

ü  If your phone gets wet, remove the battery & dry the phone with a mild blow drier.

ü  Keep your laptops safe in laptop cases & avoid talking it out too much in the rains.

ü  Do not keep your laptop bags in damp areas. Get them periodically checked in rainy season especially.

ü  Cameras also need to be taken care of in the rainy season. Use a soft dry cloth to wipe off the water from the lens.

ü  Rice is better in removing water particles or absorbing moisture. Put your wet phone or gadget in sifted rice & close it. Longer the phone or electronics device in rice drier the device will get. Approximately one day is sufficient to dry the phone or camera. You can leave gadget I rice for more than a day but make sure rice is dust proof.

ü  Keep devices unplugged when not in use in order to avoid short circuit & shocks.

ü  Keep gadgets in plastic cover for extra protection & take special care for touchscreen devices as they are more prone to damage.

ü  Remove the batteries of all the devices when not in use. This is especially true for the monsoon season that can damage devices.

STRUCTURE OF C :-

#include <headerfile1.h>#include <headerfile2.h>...#include <headerFILE.h>global declarationsreturn-type main(parameter list){statement sequence}return-type function1(parameter list)

{

statement sequence

}

return-type function2(parameter list)

{

statement sequence

}

.

.

.

return-type funcTION(parameter list)

{

statement sequence

}

NOTE: Statements in 'C' are terminated with  a SEMI-COLON (;)

Structural Analysis :-

1. #include <headerFILE.h>

Header Files are pre-processor directives that are already present in a folder named "include" that comes with C compiler. They all carry the extension .h and contain functions that have already been provided to the programmer to perform some specific task. For eg.

(a) stdio.h is a header file that contains the Standard Input/Output functions that are needed for basic input/output operations in the program.

(b) conio.h is a header file that deals with the Console Input/Output operations,i.e. dealing with the display on the Console (monitor) when the program is run.

(c) math.h is a header file that provides functions which help in mathematical operations.

2. global declarations

Global declarations are the values that can be used in the complete program or package created. These values and attributes declared globally can be accessed by  all the functionc and modules created inside the program.

3.  return-type main(parameter list)

'return-type' is the type of value returned by the function.

'main' is special. Our program begins executing at the beginning of main. This means that every program must have a main somewhere. main will usually call other functions to help perform its job, some that you wrote, and others from libraries that are provided for us. 'parameter list' - One method of communicating data between functions is for the calling function to provide a list of values, called arguments, to the function it calls. The parentheses after the function name surround the argument list. In this example, main is defined to be a function that expects no arguments, which can be indicated by the empty list ( ).

NOTE- A C program, whatever its size, consists of functions and variables. A function  contains statements that specify the computing operations to be done, and variables store values used during the computation.

The statements of a function are enclosed in braces { }.

Some of the commonly used functions in 'C' are-

1. printf()

This is a function which is used to get the output as a display on the monitor. The arguments passed to this funtion is displayed as an output. It is a library function which is stored in the header file 'stdio.h'.

2. scanf()

This is a function which is used to get the input from the user. The arguments passed to this funtion are taken as an input. It is a library function which is stored in the header file 'stdio.h'.

3. getch()

Generally to hold the output screen on the monitor Alt+F5 is used. Or an alternate way is to use getch() function which is used for the same purpose. It is a library function and is stored in the header file 'conio.h'.

Another function getche() can also be used for the same purpose. The main difference between the two is that the key pressed to return back from the output screen is displayed along with the main output display in the case of getche().

4. clrscr()

This is a library function that is used to clear the output screen and is defined in the header file 'conio.h'.

Note- The character strings are usually placed inside the double quotes ("..."). The sequence \n in the string is C notation for the newline character, which when printed advances the output to the left margin on the next line. Notice that \n represents only a single character. An escape sequence like \n provides a general and extensible mechanism for representing hard-to-type or invisible characters. Among the others that C provides are \t for tab, \b for backspace, \" for the double quote and \\ for the backslash itself.

Also note that any characters between /* and */ are ignored by the compiler; they may be used freely to make a program easier to understand.

DATA TYPES are the types of data that tells the types of values that the variable can store, the type of data that can be dealt with and the associated functions of handling it.

Flow of Control-

1. Sequential control- It is the default flow of control in the program of 'C'.

2. Conditional control- It is the flow of control  that depends upon a condition test. For eg. if-else, switch-case.

SYNTAX:

(a) if-else

if (condition)

{...

...}

else

{...

...}

(b) switch-case

switch(testing condition)

{case 1: ...

           ... break;

case 2: ...

          ... break;

case ..

..

..

default: ...

}

Note: The conditional or looping statements can be nested also. For further details, kindly Contact us and let us know your queries.

We'll surely respond as soon as possible.

3. Iterative control- It is the flow of control that repeats itself depending upon a condition test. For eg. for, while, do-while..

SYNTAX:

(a) for(initialising statement; condition test; update statement)

{ ...

... statements to be executed repeatedly...(body of loop)

..

}

(b) while(condition test)

{..

...

body of loop...

..}

(c) initialising statement

do

{...

...

..body of loop...

..}

while(condition test);

Till now we are well acquainted with the Basics of 'C' program..

WE WELCOME YOUR SUGGESTIONS AN QUERIES OVER OUR PRECISE DESCRIPTION..

Let us now begin with the basic programming to understand the syntax of various statements that we have learnt so far.So subscribe our Blog to kick off your day with our free stuff.

‘C’ is a general purpose Procedural programming language.

In contrast with BCPL and B, C provides a variety of data types. The fundamental data types are characters, and integers and floating point numbers of several sizes. Besides, there is a hierarchy of derived data types created with pointers, arrays, structures and unions. Expressions are formed through a legal combination of operators and operands. Any expression, including an assignment or a function call, can be a statement. Pointers provide for machine-independent address arithmetic.

Functions may have return values of various data  types, structures, unions, or pointers. Any may be a recursive function. Local variables are typically generated with every invocation of the function. The functions of a C program may exist in separate source files that are compiled separately. Variables may be internal to a function, external but known only within a single source file, or visible to the entire program.

An important step is to perform macro substitution on program text, include other source files, and conditional compilation.

C is a relatively ``low-level'' language. There are  no operations to deal directly with composite objects such as character strings, sets, lists or arrays, no operations that manipulate an entire array or string, although structures may be copied as a unit. The language does not define any storage allocation facility other than static definition. Finally, C itself provides no input/output facilities and no built-in file access methods. All of these higher-level mechanisms must be provided by explicitly called functions.

In 1983, the American National Standards Institute (ANSI) established a committee to provide a modern, comprehensive definition of C. The resulting definition, the ANSI standard, or ``ANSI C'', was completed in late 1988. Most of the features of the standard are already supported by modern compilers.

Here we are going to discuss 'C' from the very beginning to the extent we can reach through by gathering the most out of our studies.So subscribe our site to get our posts into your mail box. And kick off your day with our updates.

Perhaps each one of us is well acquainted with the importance of 'C' as a programming language in the computer world. 'C' was originally designed for and implemented on the UNIX operating system on the DEC PDP-11, by Dennis Ritchie. It has been called the 'System Programming Language' due to it's great deal of utility found in  designing programs for compilers and operating systems along with other big programs as well!

‘C’ holds it’s many of the important ideas from the language BCPL, developed by Martin Richards which in turn holds it’s roots in the language B, which was written by Ken

Thompson in 1970 for the first UNIX system on the DEC PDP-7. These led to the development of C in the 1970s.

For quite long, the standard for C was the version supplied with the Unix

version 5 operating system. It was first explained in The C Programming Language by

Brian Kernighan and Dennis Ritchie (Englewood Cliffs, N.J.: Prentice-Hall, 1978). In 1983 a committee was established to create an ANSI (American National

Standards Institute) standard that would define the C language once and for all. The

standardization process took six years (much longer than expected).

The ANSI C standard was finally adopted in December 1989, with the first copies

launched in early 1990. The standard was also adopted by ISO (International

Standards Organization) and is now referred to as the ANSI/ISO C standard. Today, all mainstream C/C++ compilers comply with Standard C.
