Effects Of Electromagnetic Radiation On Earth

The aim of this work is to describe various form and sources of electromagnetic radiation and its effect on earth.INTRODUCTIONElectromagnetic radiation (EM radiation or EMR) is a fundamental phenomenon of electromagnetism, behaving as waves and also as particles called photons which travel through space carrying radiant energy. In a vacuum, it propagates at the speed of light, normally in straight lines. EMR is emitted and absorbed by charged particles. As an electromagnetic wave, it has both...

SCALABLE AND EFFICIENT END TO END NETWORK TOPOLOGY INFERENCE

ABSTRACTTo construct an efficient overlay network, the information of underlay is important. We consider using end-to-end measurement tools such as traceroute to infer the underlay topology among a group of hosts. Previously, Max-Delta has been proposed to infer a highly accurate topology with a low number of traceroutes. However, Max-Delta relies on a central server to collect traceroute results and to select paths for hosts to traceroute. It is not scalable to large groups. In this paper, w...

DESIGN AN IMPLEMENTATION OF A COMPUTER BASED SEAPORT BILLING SYSTEM (A CASE STUDY OF NIGERIAN PORT AUTHORITY LAGOS)

ABSTRACT Handling of cargo has been a circular task all these while in our various ports.  And Nigerian Ports Authority (N.P.A) being an organization responsible for seeing to the affairs of our various sea ports in Nigeria, have worked endlessly to make sure cargoes are properly handled without much complain of damage or misplacement. To ease the operation of cargo handling in our sea ports, researcher took up this study by critically understanding the work, procedure involved, analys...

SEARCH-WEB BASE SEARCH ENGINE

ABSTRACTWeb base search engine is a Java application to find files that contain (or don’t contain) a given string. The string may be in plain text or it may be a Java regular expression. Such a trivial search should be part of the operating system, and in fact, once was. As bigger and more impressive features were added to Windows, it lost the ability to search files for arbitrary bytes of text. Windows 98/ME/2000 could find words buried in files with unknown formats; Windows XP and Vista s...

A SMART CARD SECURITY SYSTEM (A CASE STUDY OF ECO BANK)

ABSTRACTIn the up to date electronic planet, authentication of an individual is a vital assignment in numerous territories of everyday existence. Smart Cards are secure compact space gadgets utilized for a few requisitions specifically security identified ones including access to framework's database either connected or disconnected from the net. Smartcard are regularly “secure” movable units. It is an elevated amount outline system for installed informative data frameworks. Normally...

Reduction of Cell Phone Electromagnetic Radiation Effect on Human Body

ABSTRACTElectromagnetic waves generated by different wireless systems like mobile systems, satellite systems, microwave links…etc. facilitates our communications throughout the world. These waves have many effects on the human body as well as our daily lives. The effects of electromagnetic waves cause many problems and diseases in the human body like cancer. Nowadays, types of the cancer caused by these waves has increased, because mobile users have increased. Because of the importance of h...

SECURE DATA HIDING AND EXTRACTION USING BPCS

ABSTRACTBit Plane Complexity Segmentation (BPCS) digital picture steganography is a technique to hide data inside an image file. BPCS achieves high embedding rates with low distortion based on the theory that noise-like regions in an image’s bit-planes can be replaced with noise-like secret data without significant loss in image quality. . In this framework we will propose a collaborate approach for select frame for Hiding Data within MPEG Video Using Bit Plane Complexity Segmentation. This...

Recycling of water sachet

ABSTRACTWastes generally render our environment unfriendly and the worst of them all are those wastes that are non-biodegradable and as such, wastes of these forms (non-biodegradable) pose a serious threat to our environment.One of these categories of non-biodegradable wastes is pure water sachets. They are found in virtually every part of Nigeria and various attempts have been made to biodegrade these pure water sachets. One of these attempts was carried out byNwachukwu S.et al (2010) in the...

NETWORK PROGRAMMING USING JAVA SCRIPT (SECURED CLIENT-SERVER CHAT APPLICATION)

                                                       ABSTRACT  Several network systems are built to communicate with one another as well as made available through service-oriented architectures. In this project, the clie...

DESIGN AND IMPLEMENTATION OF SELECTIVE ENCRYPTION OF STILL IMAGE (CASE STUDY OF WOMAN OF FAITH)

ABSTRACTImages account for a significant and growing fraction of Web downloads. The traditional approach to transporting images uses TCP, which provides a generic reliable in-order byte-stream abstraction, but which is overly restrictive for image data. We analyze the progression of image quality at the receiver with time, and show that the in-order delivery abstraction provided by a TCP-based approach prevents the receiver application from processing and rendering portions of an image when t...

COMPUTERIZATION OF STUDENT MATRICULATION NUMBER GENERATING SYSTEM USING JAVA (A CASE STUDY OF FEDERAL POLYTECHNIC IDAH)

AbstractInformation, a principal resource in any business entity has become an important driver of any system. In the academic community, information is especially very important. Students within the system must register for courses approved for the semester, take examinations and check the outcome of such examinations once approved by the authorities. Years after graduating from the system, students come back for the transcripts or to get some references. It is therefore imperative to handle...

RETRIEVING FILES USING CONTENT BASED SEARCH

ABSTRACTContent Based File Search is a Java application to find files that contain (or don’t contain) a given string. The string may be in plain text or it may be a Java regular expression. Such a trivial search should be part of the operating system, and in fact, once was. As bigger and more impressive features were added to Windows, it lost the ability to search files for arbitrary bytes of text. Windows 98/ME/2000 could find words buried in files with unknown formats; Windows XP and Vist...

IMPACT OF COMPUTERIZED PHYSICIAN DOCUMENTATION IN SOME SELECTED GOVERNMENT AND PRIVATE HOSPITALS IN KANO STATE

ABSTRACTThe objective of this research is to find out the impacts of computer usage by physicians in Kano State and this is likely to increasingly replace handwritten documentation in other institutions. The population consisted of the physicians in Kano state hospitals. A questionnaire was designed and administered among 26 physicians using a simple random sampling technique. Simple percentage was used to analyze the research questions.The study found out that the physicians in Kano state ne...

REMOTE PC ACCESS IN CYBER CAFE (CASE STUDY OF PRESSURE WORLD CAFE )

ABSTRACTRemote pc access are inherently vulnerable, as any node can disrupt the communication of potentially any other node in the network. Many solutions to this problem have been proposed. In this paper, we take a fresh and comprehensive approach that addresses simultaneously three aspects: security, scalability and adaptability to changing network conditions. Our communication protocol, Castor, occupies a unique point in the design space: It does not use any control messages except simple ...

COMPUTERIZED AUTOMATED FIRE DETECTION SYSTEM USING JAVA SCRIPT

ABSTRACTFIRE ALARM SYSTEM PLAYS AN IMPORTANT ROLE in maintaining and monitoring the safe of all kind environment and situations. However the usability of many existing fire alarm system is well known but could be produce with high cost. Subsequently, it is not affordable for the low income users. The main objective of this project is to produce a prototype of Fire Detection program with low cost. The microcontroller has two main systems, the detection system and the monitoring system.The dete...
