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.

The Object Oriented Features Of C++ Topics For Students: Object is an abstraction, concept, or thing. Object has two purposes. They improve understanding of the real world and provide a basis for implementation of a computer. Objects have identity and they are distinguishable.

An object Class defines a group of objects with similar common behavior, properties, and common relationships to the other objects with common semantics. Object class has same attributes and behavior pattern. The main motivating aim of object oriented approach is to get rid of the flaws encountered.

Features of object oriented programming are, emphasis is on data than procedure, programs are divided into objects, data structures are designed to characterize the objects, data is hidden, objects may communicate with each other, new data can be easily.

The wrapping up of data and functions into a single unit is called encapsulation. It is the striking feature of a class. Abstraction is defined as an act of representing essential features by hiding background details. Classes make use of the concept of abstraction as a list of abstract attributes like weight, size, cost, and functions. The aim of abstraction is to separate those aspects that are important from those aspects that are not important.

Reusability is one more feature of OOP. Inheritance is the concept with which objects of one class acquire the properties of other class. It supports hierarchical classification concept. Polymorphism refers to the ability to make one or more forms. This operation exhibits different behaviors in different examples. Polymorphism basically has two types, Compile time Polymorphism and Run time Polymorphism. C++ has various operators that manipulate data of the primitive data types such as operator overloading.

Conclusion:

Object-oriented programming (OOP) is a computer programming that uses objects, data structures that consists of methods and data fields with their interactions to design computer programs and applications. This technique includes many features like data abstraction, encapsulation, polymorphism, and inheritance.

Storage Area Network SAN Paper Presentation for CSE: Data perceived today is the key for various organizations like stock exchange, banking, government record etc. It is an explosive demand for data storage and this demand is addressed by deploying SAN. The activity of sharing a single large storage device over many applications has made SAN an attractive application in today’s market.

In today’s computing network, data theft, fraud, hacker attempts, and human error exchange across the public networks like internet. Data storage networking venders are rapidly deploying and developing security frameworks for protection of data stored. It helps to ensure safe and reliable data processing over a storage area networks (SAN).

One thing to remember about SAN security is that SAN is a vulnerable network to the sorts of vulnerabilities. SAN resources are protected by physical security and the hosts should meet stringent security requirements.

Storage area network is a dedicated centrally managed infrastructure. It enables interconnection of server and data storage system. Basically, it is a high speed network behind LAN/WAN networks. It is optimized for data I/O operation and storage management. It facilitates sharing of resources, universal access, supports unpredictable information technology growth, improves information protection, provides affordable 24 x 365   availability, and disaster tolerance.

SAN removes data traffic during backup process which increases network performance. It improves data access that provides high speed network communications. It helps to centralize management of system and consolidate backups, increasing overall system efficiency. It is added to the network with minimal disruption.

SAN is broadly classified into three layers. They are Host Bus Adaptors, SAN Network, and Storage Devices. SAN Management is a combination of two managements, Storage Management and Network Management.

Conclusion:

SAN is a data centric network. It is deployed over networks and devices for data management and enterprise growth where data security is of main concern. The storage networking association has built a working area and will come out with specifications and standard recommendations.

Steganography Student Seminars: Steganography is an art and science of hiding information by embedding messages within an object. It is seemingly harmless messages. It is useful in various areas like personal, military, diplomatic, and intellectual property applications. Steganography is the term which is applied to much number of processes which will hide a message within an object. The hidden message is not visible to an observer.

Steganography is an art with which writing is hidden with the help of recovery by the minds of men. Though people have hidden secrets throughout the ages, the recent development in technology and computational power has propelled to today’s security techniques. Steganography literally means hidden writing or covered writing that is writing is known to casual observer.

Steganography solves this problem by hiding the sensitive and secret information in a harmless file called carrier file. Steganographic software allows information which is hidden in graphics such as sound files. By this technology, data can be hidden in a normal picture without altering its appearance or size. The hidden messages do not need to be encrypted and it can be plain like everyday English.

Steganography has two types. They are Fragile and Robust. Fragile steganography is embedding of information into a file, which is destroyed if the file is altered or modified. Robust marking aims to embed information into a file, which cannot be destroyed easily.

An attempt to detect the use of steganography is called Steganalysis. It is the task of detecting and disabling steganographic information. It can be either passive or active.

Conclusion:

Steganography is a dynamic tool and capability to adapt new technology. It has its own position in computer data security. One can deduce that usage of steganography is growing with the amount of commercial tools present today. Steganography is another tool to hide data. Hiding a message decreases the message detection with steganography methods.

This paper Video Fingerprinting and Encryption Principles MCA Final Seminar shows a tutorial of video scrambling algorithms and digital fingerprinting based on partial encryption. So we focus on the problems of encryption and video fingerprinting.

In constrained communication applications, multimedia security algorithms enable digital rights management (DRM). We focus on the video-on-demand (VoD) business model where subscribers request and receive video information to service provider at scheduled intervals. In a DRM context, the primary objective of fingerprinting and encryption is to protect video content from various attacks made by one or more attackers.

Overall, this article is based on two folds.  First one is to present a tutorial of the emerging areas of video fingerprinting, state-of-the-art review, and encryption highlighting design challenges for multicast environments. The second one is to propose the approach of joint fingerprinting and decryption (JFD) to establish a compromise between practicality and security for DRM applications.

Consider a single transmitter, which can be a VoD server to refer to source or server that communicates with any number of receivers that we call users. In every situation, the source should be responsible for embedding the global group watermark which may contain copyright and ownership information.

Using secret key cryptography, it is also responsible for encrypting the media content which is common for all users. The use of a group key for encryption enables multicast communications but needs more sophisticated key management. Fingerprinting can be done either at the transmitter or receiver and separate or integrated with the cryptographic process.

Conclusion:

This document provides an overview of various issues that should be addressed for video encryption and fingerprinting in a DRM context. By giving the thrust toward security, a solution is needed that give a better compromise between security and complexity. Low-complexity security solutions should take careful account of the application, dependent restrictions and competing objectives.

The objective of this Parallel Data Mining Of Association Rules BE Seminar is to generate association rules. This document cover problem of parallel mining of association rules on distributed memory multiprocessor machine. Parallel mining of association rules describe a spectrum of trade-off between memory usage, communication, computation, synchronization and use of problem specific information. “Apriori” parallel algorithm is implemented by which performance is measured and shows a good speed up behavior when compared to sequential implementation.

The growth of scientific, business, and government databases sizes has outpaced our ability to interpret and digest the stored data. This is a need for new generation tools and techniques for automated and intelligent database analysis. These generated tools and techniques are the subjects of data mining.

Data Mining is the process of analyzing data and summarizing into useful information from different perspectives. This Information is used to increase revenue and cut the costs or both. This mining software is used to analyze data, which is one of the best analytical tools.

The primary goal of Data Mining is to obtain knowledge that a user can act on and it is done by building a model of real world from a variety of sources, which include customer’s history, corporate transactions, customer demographic information, and relevant external database.

The major goals of Data Mining are Prediction and Description. Prediction involves usage of fields of the database to predict the unknown values of the variables of interest. Description focuses on finding human-interpretable patterns that describes the data.

The Data Mining approach is generally categorized into six-types. They are Classification, Regression, Time Series, Clustering, Association Rules and Sequence Discovery.

Conclusion:

Implementation of the Apriori Algorithm for Mining of Association rules, it is difficult to carry large amount of data for greater accuracy in a given amount of time. Size up provides sub linear performance as the numbers of transactions are more. It has good speed up performance.
