The Eyegaze Communication System is a communication and control system with complex physical disabilities available for people. The system is run with your eyes. On looking at control keys available on a screen, a person is able to synthesize control his environment like lights, appliances, etc, and control speech, type, run computer software, operate a telephone and mouse, and access the Internet. This system is used to attend school write, books, and optimize the quality of routine life of people with disabilities over the world.

A very good system from computer industry, Eyegaze, a communication & control system which you run with your eyes. The Eyegaze System is a control system and direct-select vision-controlled communication. This system was developed in Fairfax, Virginia, by LC Technologies, Inc.

This system is developed especially for those people who cannot use their hands or voice so the only requirements is to operate the Eyegaze. It is control on one eye with vision & ability to maintain the head fairly still. This System is used around the world.  Its users are mainly adults and children suffering from cerebral palsy, spinal cord injuries, brain injuries, ALS, multiple sclerosis, brainstem strokes, muscular dystrophy, and Werdnig Hoffman syndrome.

These systems have been using in schools, hospitals, homes, offices, and long term care facilities. A person can control his environment and do many activities using this system. To use this system, the user must have skills like good control of one eye, adequate vision, and to maintain a position in front of the monitor.

Conclusion:

With today’s technologies, the human eye-gaze can be recorded by unremarkable techniques. The basic reason for eye-gaze based user interfaces is that it is a potential porthole into the cognitive processes and communication with the direction of the eyes which is faster than any mode of human communication.

Unix File System Engineering Seminar Topics: To ease access to nonvolatile storage using a file system is intrinsic to the UNIX programming paradigm. A File is an important abstraction in the programming field. Files serve as storage data permanently. The file system is the method the operating system manages, organizes, and maintains the hierarchy of file into mass-storage devices, hard disks.

In UNIX, everything can be assumed as a file even physical processes and devices. The UNIX file system follows hierarchical system. Every file is within a directory. Every directory is within other directory excluding the highest-level directory or the root directory which is the forward slash “/”.

Users own the files and can determine the access to files and directories. A simple file is a series of bytes which is addressable to byte granularity and it functions as a non-volatile storage.

UNIX file name space contains hierarchically nested directories with files. Files are accessed with standard library interfaces command line utilities accessible to application software. UNIX provides an easy access to files.

A UNIX file is storage of information. It is a sequence of characters. A file consists of bytes which we put in a source program or executable code. It does not have size or attributes or end-of-mark or name. Though everything is defined as a file by UNIX, it is divided into three categories. They are Ordinary files, Directory files, and Device files.

Conclusion:

The file system contains information pertaining to files at various places with suitable links among them. System administrator should have the knowledge of file system to fix inconsistencies which tend to crop up. As UNIX handles everything as a file, it could not make difference between many types of file, so it is easy to treat all types of files in the same manner. UNIX system is the first file system that provides the hierarchical structure.

Unique P-Mail Addressing an Internet Based Application: The modern way of learning is Internet technology. Moreover, the Internet is facing many problems such as hacked by intruders and many threats. To overcome these problems, we have got concept of P-Mail addressing systems (Personal mailing systems). For this, an ID will be allotted to the child and may not be hacked by anyone. Fingerprints, retina scan, or heartbeat is used as a password. This chip can communicate with the satellites and it provides great security than any other.

Internet is an interconnected computer networks, used worldwide. The Internet is a network of convergence of media computers and telecommunications. The type of technology we are utilizing today is facing many problems. The technologies used in these systems are Embedded Systems with Digital Signal processing & Biometrics Identifications.

According to the concept of P-mail systems at the time of birth of a child, a chip would be inserted in the new born child in the form of a molecule. This chip would be connected to the main nerves that control the brain and it accessed through satellite. It allocates a number to that child or UNIQUE name, which is called P-mail address (Personal Mail Address). This would be his identification code like his name.

The chip has very important role in this concept of P-mail systems. The chip would be embedded software, which performs many tasks such as Internet is a way through which the whole world is connected by using the P-mail address, Global Positioning System permanently activated, no need to carry cell phones, lap tops, no heck to remember ID and password, and passwords cannot be hacked.

Conclusion:

The above concept of P-mail systems plays a very important role in human life. It takes care of all the tasks done by the human. With the help of this technology, global positioning is achieved. GPS system is accessed by many devices.

UML Seminar Topics For Computer Science: With UML features, software can be used in more realistic method with Generalization, Association, Dependency relationships and Graphical symbols. Software engineering has two technologies Forward Engineering and Reverse Engineering and which is used to save Time, Money and Energy.

Software is a set of different programs, when executed, provides a desired features, functions, and performance. S/W is a logical rather than physical element. Software engineering (SE) is the profession of people who create and maintain software systems by using practices and technologies from project management, computer science, engineering, application domains and other fields.

UML stands for Unified Modeling Language. It is an object-oriented system of notation. This language is accepted by the Object Management Group (OMG) as the standard for modeling object oriented programs. It has nine types of diagrams. By using these diagrams, we can simplify the given s/w project easily.

Class Diagrams are the backbone of UML. They describe the static structure of a system. Object Diagrams describe the static structure of a system at any particular time, which are used to test class diagrams for accuracy. Use Case Diagrams model the system functionality using actors and use cases. Collaboration Diagrams represent interactions between objects and describe static structure and the dynamic behavior of a system. Component Diagrams describe the organization of physical software components which include source code, run-time (binary) code, and executables. Deployment Diagrams depict the physical resources in a system including nodes, components, and connections. Activity Diagrams illustrate the dynamic nature of a system by modeling the flow of control from activity to activity. Associations represent static relationships between classes. Generalization or inheritance is a relationship between two classes. Dependency defines a relationship, in which changes to one package will affect another package.

UML Seminar Topics For Computer Science Conclusion:

Using these UML features, it is easy to simplify the given project in more advanced method and using UML diagrams, we can represent the software in more realistic way.

Tool Command Language Seminar: TCL/TKs (Tool Command Language/Tool Kit) is a small, interpreted, language which is embedded. It can access graphics and system features and is extensible. It is a multiplatform and provides wide support.  It can be downloaded on the internet. It runs TCL scripts for backend processing. TCL is a language known as the Tool Command Language.  TK is a set of extensions or widgets to add graphic capability to TCL interpreter. It includes things such as radio buttons, check boxes, list boxes, entry boxes etc. TCL has a relationship to TK like VBs relationship to activex.

Initially, TCL was intended to be a reusable command language. The developers had been creating a number of interactive tools which require its own command language. TCL has been used as a scripting language. TCL is used with TK library, a set of procedures and commands which make easy to program GUI. The most useful feature of TCL is its extensibility. TCL is very easy to extend and these are available on the internet for free.

Scripting languages like PERL and TCL has a very different programming than system programming languages like C or JavaTM. They use typeless concept to achieve a higher level of programming and application development. To increases the computer speed and changes in the application, scripting languages are needed.

In short, scripting languages are designed for gluing, assumed to be a set of powerful components for connecting components together. System programming languages are helpful to manage complexity whereas scripting languages are typeless for connections between components. It provides rapid application development usages.

Conclusion:

Scripting languages and system programming languages are complementary. Typically, these languages are used in component frameworks where components are created with system programming languages and glued together with scripting languages. TCL won two major awards, ACM Software System Award and USENIX Software Tools User Group (STUG) Award.

Three Dimensional Data Storage Seminars For Btech Students: Tape storage is less susceptible to hacking and data theft problem. It is easily portable. It reduces overall costs for storage. Holographic storage is a breakthrough technology which stores data and information within its volume. It stores data either magnetically or optically. The Holographic storage uses the space with optical characteristics, which are similar to create 3D holograms. It uses laser, optics, images sensors and special crystals. The concept of fluorescent cards/disc (FMD/c) multi-layer is a breakthrough which solves the problems of signal degradation associated with technologies of CD and DVD.

It is recognized that two-dimensional carriers are not sufficient for future generations of memory devices. The research focused on methods to develop three-dimensional storage with the help of holographic technology and multi-layer storage technology. We know that data storage technology like CD/DVD and floppy are not having enough capacity to store large amount of data. They are called one dimensional devices or two-dimensional devices.

Floppy and CD are called one dimensional storage devices because they can read/write only on the one surface of the storage medium whereas the DVD is called the two dimensional device because it can read/write on the two layer in the storage medium. In the 3-D storage devices, the data storage can be done on more than two layers of single storage media.

There are two types of 3-D storage technology, Holographic Storage Technology and Multi-layer Storage Technology. Both technologies are presently in developing phase. With holographic storage technology, the speed of retrieving the data is in tens of microseconds when compared to a data access time of nearly 10 milliseconds offered by the fastest hard disk.

Conclusion:

The future holographic storage drive will provide symmetrical infinite double sided disc or tape to read and writes with drive densities of 200terabits/sq.in.and up. This will store much data than any other drive much faster and will add at least 1000 times the data storage.

The Socket Interface Seminar Topics For Students: There should be an interface between the protocol software and the application programs to use the network facilities. This document is on a model of an interface between TCP/IP protocols and application programs. A programmer should be familiar about the interfaces to use TCP/IP.

UNIX is input-output (I/O) primitives that follow a paradigm which is often referred to as open-read-write-close. Initially, UNIX programmers cast all I/O operations in the open-read-write-close paradigm. The devices used are keyboards, disks and files. Network protocols are more complex than conventional I/O devices so a group of network protocols is added to UNIX decided for the interaction between user processes and network protocols. This addition to UNIX enhanced the complexity of I/O interface substantially.

A Socket is referred as an end point for communication. The pair of processes communicating over a network processes a pair of sockets-one for each process. It is made up of an IP address which is concatenated with a port number. Sockets use client-server architecture in which client makes request to the server and the server accepts and processes it to complete the connection. The basis for network in UNIX lies on an abstraction which is nothing but a socket.

Conclusion:

The interface between an application program and TCP/IP protocols lies on the operating system because TCP/IP protocol software resides in an operating system. To use TCP/IP, a socket must be created and bind addresses to it, accepts incoming connections, and communicates with the read or write operation.  The socket interface is very popular and is supported by many vendors. There is a Java socket class which implements time-of-day server. The client makes requests the time of day from the server. The server listens and after a connection is received, the server returns the time of the day to the client.
