Abstract

While a data warehouse is designed to support the decision-making function, the most time-consuming partis the Extract Transform Load (ETL) process. Case in Academic Data Warehouse, when data source came from thefaculty?s distributed database, although having a typical database but become not easier to integrate. This paperpresents how to an ETL process in distributed database academic data warehouse. Following Data Flow Threadprocess in the data staging area, a deep analysis performed for identifying all tables in each data sources, includingcontent profiling. Then the cleaning, confirming, and data delivery steps pour the different data source into the datawarehouse (DW). Since DW development using bottom-up Kimball?s multidimensional approach, we found the threetypes of extraction activities from data source table: merge, merge-union, and union. Result for cleaning andconforming step set by creating conform dimension on data source analysis, refinement, and hierarchy structure. Thefinal of the ETL step is loading it into integrating dimension and fact tables by a generation of a surrogate key. Thoseprocesses are running gradually from each distributed database data sources until it incorporated. This technicalactivity in distributed database ETL process generally can be adopted widely in other industries which designer musthave advance knowledge to structure and content of data source.

Abstract

Data encryption is well known as essential for today?s technology. ElGamal encryption and RSA algorithmis made before storing mails to mail server. ElGamal decryption and RSA decryption is made after retrieving mailsfrom mail server. This system is implemented to secure mail server system for local government?s important mailmessages. These algorithms consume a considerable amount of time and resources of memory, CPU time, andcomputation time to encrypt and decrypt data. This paper discuss the results comparison of these algorithms in termof encryption time, decryption time, and memory usage over variable file sizes. The results show that RSA does fasterencryption process in compare with ElGamal. However, ElGamal decryption process is quicker than RSA. This systemis also expressed comparison of storage Size between RSA and ElGamal. Both of these algorithms are cryptographicpublic-key algorithms but have roles in different techniques. This system is using C# programming language and SQLServer to store mail messages.

Abstract

Reliable broadband communication requires secure high data rate and bandwidth links. With the observedincrease in broadband users, known communication systems such as RF and microwave links cannot promise suchrequirements due to link interference and low bandwidth. A current communication system that promises suchrequirements and more is Free Space Optical (FSO) communication. This system basically involves the transmissionof signal-modulated optical radiation from a transmitter to a receiver through the atmosphere or outer space. However,location-variant atmospheric channel degrades the performance of an FSO system under severe atmosphericconditions, thus necessitating local atmospheric attenuation studies.This paper presents the characterization of both fog- and rain-induced attenuation and the performance ofan FSO system in a terrestrial terrain at Akure, Nigeria. One-year archived visibility data and in-situ measured 1-minute integration time rain rate data obtained from Nigerian Meteorological Agency (NIMET) and the Departmentof Physics, Federal University of Technology, Akure were used to compute the fog- and rain-induced specificattenuations using Kruse model and Carboneur model respectively. The performance of the FSO system is analyzedthrough link margin by using the parameters of a commercial optical transceiver, Terescope 5000.

Abstract

Perimeter intrusion detection systems are an integral part of most physical security systems. The mainfocus of the Perimeter Intrusion Detection System (PID) is on the fence intrusion. To secure public and private placessuch as military bases, airports, power station and security related application, the used of perimeter fencing iswidely applicable for isolating and protecting. Fence structures merely prevent a percentage of intrusions orpostpone them. Therefore, to monitor and investigate activities on or around the university, a higher level of securityis needed. The system used major components as Arduino board, 8x8 LED display, ultrasonic sensor, 16x2 LCDdisplay module and speaker. The unauthorized person who tries to intrude the university woulld be sensed, detectedand alarm would generate a signal that an intruder was trying to enter the university. The sound level depended onthe distance, the nearer the intruder and stronger would be the alarm signal. PID system displayed the distance of theobject or personal found in its region on the LCD display. This system was very useful for security applications.Ultrasonic sensor would be searching if there was a motion in its range.
