Our project service ranges from focused one-day sessions to comprehensive multiple-day project-development method. We develop university acceptable projects of Embedded, VLSI Design, and Micro-controller based Projects, Robotics, and Image processing projects, Signal processing projects, etc.

We work on customized projects that are unique and having own ideas and innovations. we develop projects for you which are never done before. You can customize the software system and hardware requirements according to your project ideas. {We can/we will/we are able to} develop the projects that are specific to the needs.

DSTARENA have the option for the students to decide on whether to get involved in the whole process of project development or whether they need only the project completion kit without involving in various stages. We’d like to remind the students that ITT Systems has a list of free Servers you can download for the use of this project. We provide 24/7 online/offline support until the complete project delivery stage.

For customized projects, you can send us your requirements and we’ll analyze its feasibility. You can additionally speak to us directly to communicate your requirements to our developer.

DSTARENA will be provided with following:

  1. Complete Project Hardware Kit.
  2. Project Abstract, Circuit Diagrams, Block Diagrams, and Flowcharts.
  3. Project working procedure.
  4. Documents/Data Sheets related to all the components used in the project.
  5. Project Confirmation/Acceptance receipt and Completion Certificate.

 

SQL: Structured Query Language basics

Structured query language is abbreviated as SQL. SQL has three classification of command languages, they are :

  1. DDL: Data Definition Language
  2. DM: Data Manipulation Language
  3. TCL: Transaction Control Language

These three command languages help one to access SQL, using this one can create, update, manipulate, save and delete database tables.

DDL

DDL or Data Definition Language is used to describe the basics of a table, it defines the database tables. In this we have following commands:

  1. Create

This command is used to create a new table in a database.

Code:  >>create table tablename ();

>> create table employee ();

The above command creates a table with name employee but this table will have no attributes in it. To add attributes we have to write in this form;

>>create table employee (empname varchar2 (30),

empno number (4),

 empbranch varchar2 (10));

The above table is now created with  three attributes employee name as empname; employee number as empno;  employee branch as empbranch.

  1. Alter

Alter can be used in two ways:

  • To add a new column:

>>alter table employee add (empcity  varchar2(20));

This adds a new column to table employee named employee city as empcity.

  • For modification of existing table (empno  number(5));

>>alter table employee modify (empno  number(5));

This modifies table employee, it column empno with datatype number (4) to number (5).

  1. Drop

This helps in dropping the table or delete the whole table from the database.

>>drop employee;

  1. Desc

This command describes the table and its columns having its type and other attributes.

>>desc employee;

  1. Truncate

This command is used to delete all the data from the table;

>> truncate table employee; //this delete all the data from the table.

Stay connected to our next post we will be dealing with  DML And TCL.

How to Work on Graphical User Interface (GUI) in MATLAB?

A graphical user interface provides the user with a familiar environment in which to work. This environment contains pushbuttons, toggle buttons, lists, menus, text boxes, and so forth, all of which are already familiar to the user so that he or she can concentrate on using the application rather than on the mechanics involved in doing things. However, GUIs are harder for the programmer because a GUI-based program must be prepared for mouse clicks (or possibly keyboard input) for any GUI element at any time. Such inputs are known as events, and a program that responds to events is said to be event driven. The three principal elements required to create a MATLAB Graphical User Interface are

 

1.Components. Each item on a MATLAB GUI (pushbuttons, labels, edit boxes, etc.) is a graphical component. The types of components include graphical controls (pushbuttons, edit boxes, lists, sliders, etc.), static elements (frames and text strings), menus, and axes. Graphical controls and static elements are created by the function UI control, and menus are created by the functions UI menu and UI context menu. Axes, which are used to display graphical data, are created by the function axes.

2. Figures. The components of a GUI must be arranged within a figure, which is a window on the computer screen. In the past, figures have been created automatically whenever we have plotted data. However, empty figures can be created with the function figure and can be used to hold any combination of components.

3. Callbacks. Finally, there must be some way to perform an action if a user clicks a mouse on a button or types information on a keyboard. A mouse click or a keypress is an event, and the MATLAB program must respond to each event if the program is to perform its function. For example, if a user clicks on a button, that event must cause the MATLAB code that implements the function of the button to be executed. The code executed in response to an event is known as a callback. There must be a callback to implement the function of each graphical component on the GUI. The basic GUI elements are summarized in Table 1.1, and sample elements are shown in Figure 1.1. We will be studying examples of these elements and then build working GUIs from them.

What is MATLAB?

MATLAB (matrix laboratory) is a numerical computing environment and fourth-generation programming language. MATLAB stand for matrix laboratory which is a programming language for algorithm development, data analysis, visualization & numerical computation, MATLAB is a technical computing language for engineer & scientist in industry & academia. This solves fundamental problems of engineer & scientist & it support s the vector & matrix operation. It enables fast development & execution. MATLAB lets you execute commands or groups of commands one at a time, without compiling and linking, enabling you to quickly iterate to the optimal solution. By the MATLAB language, you can program and develop algorithms faster than with traditional languages & provides all the features of a traditional programming language, including arithmetic operators, flow control, data structures, data types, object-oriented programming (OOP), and debugging features. because you do not need to perform low-level administrative tasks, such as declaring variables, specifying data types, and allocating memory. In many cases, MATLAB eliminates the need for ‘for’ loops. As a result, one line of MATLAB code can often replace several lines of C or C++ code.

  • MATLAB==MATrix LABratory
  •  It is widely used to solve different types of scientific problems.
  • The basic data structure is a complex double precision matrix.
  • Matlab is a software package for high performance numerical computation and visualization.
  • It provide hundreds of built in functions for technical computation, graphics and animation.
  •  Numerous functions for 2-D and 3-D graphics are available.

  • Basic building block of Matlab is MATRIX and fundamental data type is array.
  • Its built in function provides excellent tools for linear algebra computation. Data analysis, signal processing, optimization, numerical solution of ordinary differential equation, quadrature, and many others type of scientific computations.

SYNTAX

The MATLAB application is built around the MATLAB language, and most use of MATLAB involves typing MATLAB code into the Command Window (as an interactive mathematicalshell), or executing text files containing MATLAB code and functions.
