The Role of Mass Media in Rural Development of Pakistan

The Role of Mass Media in Rural Development of Pakistan

Mass media, the fourth pillar of democracy plays a pivotal role in up-keeping the socio- political system of a country sound and healthy. Due to the advancement of information and communication technology (ICT), the role of mass media has been multiplied to a higher order. Man has conquered time and space due to this modern technology.Mass media really connects the whole universe with a noble mission to share the sorrows and sufferings, pains and strains, success stories of the society. It always, if properly managed, takes a vital part in political affairs.Mass media perform the role of a dynamic watchdog and erects its fingers towards any backlog in a system. It diagnoses the system and opens the pitfalls and tries to rectify it.In this sense, it is a comprehensive and multidimensional concept and encompasses the development of agriculture and allied activities, village and cottage industries, socio-economic infrastructure, community services and facilities, and above all the human…

Software Architecture for Centralized Health Database

Software Architecture for Centralized Health Database

Health ‘R’ Us is a Journal handling system which is used by health care departments for storing and managing journal and journals. Electronic journal is used to accompany the patients from the first visit to the hospital including initial checkups, medications which include examination by doctor and all the medical data related to the patient. The system will be used by the hospital as well as care centers. The system will insure security by providing proper user privileges. The system also has a backward compatibility options that is we can also enter the information of the patient either adding manually or by migrating the data of patients from the previous system. The system will be able to fetch and send journals to other hospital and care center. Data and Network security is handled by the system through Secure File Transfer Protocol (SFTP). This software is used by hospitals or health care centers through PC’s and thin client devices. The system will communicate with…

Music Piracy Culture on the Internet

Music Piracy Culture on the Internet

The purpose of «Music Piracy Culture on the Internet research» was to identify the motivations behind online music piracy on the Internet through Peer-to-peer (P2P) Networks and opinions on copyright laws. The research was carried out as a Master’s Thesis in the Digital Culture program at the University of Jyvaskyla. Quantitative research methodology was utilized in the form of questionnaires, which were distributed for two weeks through the mailing list at the University of Jyvaskyla and personal invitations. Analysis of the questionnaires revealed opinions that people conduct music file sharing on P2P networks because it is convenient, promotes musicians and is environmentally friendly. In addition, the research discovered the growing popularity of online streaming as an alternative to downloading. Based on the research, some recommendations that can be proposed to music producers and musicians in the near future include; more education on copyright issues, more promotion of online…

Information Hiding Text in Image

Information Hiding Text in Image

Sensitive and confidential information is vulnerable to various kinds of misuse when data contained in, or transmitted to / from computer systems they may exposed to passive and / or active threats . Consequently, mechanisms must be provided for the protection of unauthorized access, undetected deletion, modification or insertion of the false information. To meet these requirements cryptographic techniques, must be employed which include, encryption algorithms, that encipher the message (plain text), into unintelligible cipher text, using ciphering key. Decryption algorithm is an inverse transformation used to recover the original message . The cryptography is currently an engineering subject in which there are more facts and rules .The digital image I (x, y) is represented as two-dimensional array of data, where each Pixel value corresponds to the brightness of the image at point (x, y). Digital image types can be divided into four categories, the first is called Binary Images,…

Simulation and Test-System of Vehicle Body CAN Bus — A Project Report

Simulation and Test-System of Vehicle Body CAN Bus — A Project Report

CAN is serial communications protocol which efficiently supports distributed real time control with very high level of security. CANoe v7.6 which is the product of a German company Vector is a practical and powerful tool for system design and analysis of CAN networks and others (FlexRay, LIN,etc.). Firstly, a design scheme of simulation and test system for vehicle body CAN bus network is brought forward, which mainly includes the topology of network, the hierarchical model of network and the selection of bus baud rate. Secondly, a method of how to use CANoe to construct the simulation and test environment for vehicle body CAN bus system is implemented. Finally, the simulation and test system for vehicle body CAN bus is completed by CANoe v7.6. The results are also be verified on FlexDevel board. The FlexDevel boards consist of MPC5567 chip and many input ports and output ports. Experiments that are done demonstrate that the development method of simulation and test system is feasible.

Oracle для профессионалов. Технологии и решения для достижения высокой производительности и эффективности

Oracle для профессионалов. Технологии и решения для достижения высокой производительности и эффективности

Книга представляет собой универсальный источник глубоких знаний о проектировании, разработке и администрировании приложений Oracle. В третьем издании продолжается исследование применения баз данных Oracle для построения масштабируемых приложений, которые эффективно функционируют и создают корректные результаты. Том Кайт и Дарл Кун придерживаются простой философии: вы можете трактовать базу данных Oracle как черный ящик и только помещать туда данные или же вы можете полностью разобраться в ее работе и эксплуатировать как мощную вычислительную среду. Выбрав второй подход, вы обнаружите, что остается совсем немного задач по управлению информацией, которые невозможно решить быстро и элегантно. В полностью пересмотренном третьем издании раскрываются особенности разработки приложений вплоть до версии Oracle 12c. Большая часть нового материала посвящена появившемуся набору облачных средств Oracle и применению подключаемых баз данных. Каждое новое средство объясняется в манере,…

Information Systems Development

Information Systems Development

Information Systems Development- A Software Engineering Approach focuses on the evaluation model of ISs development in software developing SMEs in India. Information systems have to be effective and efficient for long term to keep pace with today»s global business scenario. For effectiveness / success , ISs must be developed with the standard and proven methodologies of IS development,like software engineering, for nurturing information systems. These practices are non-prevalent in software developing Small and Medium Enterprises (SMEs). Thus a standard model of IS development with a Software Engineering approach is the need of an hour so that SMEs can evaluate the present scenario of IS development practices. The book aims at the design of such model of IS development which reflects the effect of strategic alignment of IS; IS development approach and IS project Management on IS development. The book has been designed to help software professionals, academicians and…

Digital Watermarking using Complex Wavelets

Digital Watermarking using Complex Wavelets

Digital watermarks emerged in the last decade as a possible solution for protecting the copyright of digital materials. We introduce complex wavelets as a novel transform for watermarking images. The complex wavelets transform has similar properties to the human visual system and experimental results show that watermarking systems designed using complex wavelets have good performance. Two different watermarking systems are considered here. The first one is based on the principles of spread spectrum communications. An alternative matched filter is proposed for watermark decoding, which is shown to have better performance than the conventional matched filter, when the underlying signal is non-stationary. The second watermarking algorithm is based on a hybrid combination between quantisation and spread spectrum techniques. This is due to the fact that watermarking can be considered as communication with side information. Finally, we suggest ways in which the watermark decoder performance…
