Abstract

With technology advancement people have started using different type of memory devices for storing dataand keeping it secure has become concern in today?s world. Universal Serial Bus (USB) flash drives are leadingportable storage device for storage and easy transfer of data from one computer to another. The usage of USB hasgrown exponentially and without security the data on the disk is at risk. Nowadays USB manufacturers offer passwordprotection and fingerprint authentication to secure the USB data. In this paper, USB is devised as a highly securedportable boot medium with fingerprint authentication to secure the data.

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

describes the pattern of relationship between internet usages on students, on the assessment of aspects of selfregulated learning. The aspect of self-regulated learning measured from 10 aspects. This study discusses the effects ofgender, the categories of schools (excellent schools and regular school), the total value of self-regulated learning andthe value of math exams. In brief, the research stages consist of three stages. The first stage of research is to createand retrieve the questionnaire data. The goal is to obtain all things related to internet usage, as well as measure aspectsof self-regulated learning assessment. The second stage of treatment on students. This treatment time is done for fourmonths, where students follow the math lesson with self-regulated learning method. Students provided with multimediadevices, textbooks and other. The third stage is the assessment or math test. The analytical method used is qualitativemethod with descriptive statistical approach. The results obtained that the dominant male students using internet forgames tend to have greater Aspects of Finding and Utilizing Relevant Learning Resources. While female, tend to bedominant in aspects of Evaluating Learning Processes and Results. The average mathematical exam results, in studentswho often use the game tend to have a higher value, compared with other students who often use social media.

Abstract

an expression of conflict in the field. To overcome this problem is a regulation of several parameters,including regulation of planting schedules and reduction of land area. The model of the irrigation water managementsystem used is based on the risk of land failure and the optimum area of land that can be planted. The parameters usedto overcome this problem are planting schedules, risk of land failure and factor k. The k factor is the ratio of wateravailability to water needs. The output of this system is optimal net benefit based on the optimal alternative irrigatedland area. The results of the formula will show the optimal amount of land area that produces optimal net benefitsbased on certain planting schedules and certain effective rainfall. This system will also show that optimization will beachieved if there is a water balance between the availability and needs of irrigation water. The system referred to inthis study is a dynamic system. The purpose of this study is to make a preliminary design of a dynamic system to optimizethe irrigation system of agricultural land. The results obtained in this study were in the form of feedback loops andinteractions between loops with each other in agricultural irrigation systems.

Abstract

This research is intended to evaluate the efficiency of proceures and processes used by the King AbdulazizInternational Airport (KAIA) in Jeddah, Saudi Arabia with the help of Six Sigma. For, we have framed differentobjectives for analyzing the effect of six sigma in decision makings and quality control of the KAIA. The aim is also tofind out the relationship of Six Sigma on an information system used by KAIA. We have used the qualitative researchmethod (semi-structured interview method) with the target population of five employees working at KAIA. Qualitativedata was collected from participants through transcribed, audio-recorded and codes. Thematic analysis was carriedout in order to obtain the study result. Our study finds that there is a significant effect of Six Sigma in streamlining ofall the processes of KAIA, which contributed towards the improvement of the quality and providing better control. Wefound that the KAIA applies KPIs to measure the decision makin, empowering the decision makers or managers. Wehave also reflected on the role of Six Sigma towards the effective performance of individuals in finance, customersupport, and internal business process and team development.
