Exploring the Pattern of Habits of Users Using Web log Squential Pattern

Web mining consists of three aspects: Web content mining, Web structure mining, and web usage mining. The most important application of web mining is targeted advertising. Sequential mining is the process of applying data mining techniques to a sequential database for the purposes of discovering the correlation relationships that exist among an ordered list of events. An important application of sequential mining techniques is web usage mining, for mining web log accesses, where the sequences of web page accesses made by different web users over a period of time, through a server, are recorded. This paper proposes web log sequential pattern mining using Apriori-all algorithm. We called as Apriori-all Web log Mining. The experiment will be conducted base on the idea of Apriori-all algorithm, which first stores the original web access sequence database for storing non-sequential data. The experimental result will be given with analysis on further refinement.

Attendance system on Android smartphone

Attendance system which is currently excist still has weaknesses. The first is the long queues in front of the attendace machine at the time to come to work and leave work. The second is cheating, employees can ask her/his friend to do attendance process. The third is mostly attendance system has not been connected with the payment system in human resouces software or in the finance department. The fourth, employees who work outside the office can not do attendance process. In this paper, we introduced an attendance system based finger print technology and GPS using a smartphone integrated with payment system that will eliminate all the problems above. Our research also based on prediction that in the next few year all the smart phone will have a fingerprint scanner.

Performance Measurement of Higher Education Information System Using IT Balanced Scorecard

Extensive research was conducted at a private university in Indonesia into the performance of the higher education information system, called SIPERTI. The IT Balanced Scorecard framework consisting of its four perspectives: Corporate Contribution, User Orientation, Operational Excellence, and Future Orientation was employed to assess the system. The study was accomplished in the form of ai?źquestionnaire composed of five-point Likert scale statements. The questionnaire was addressed to the members of the faculties and staff of the university who used SIPERTI in their everyday work. The data obtained was statistically analysed including the tests of reliability and validity. A structured interview which followed the questionnaire allowed for the formulation of recommendations on SIPERTI performance improvement.

Server for SQLite database: Multithreaded HTTP server with synchronized database access and JSON data-interchange

SQLite database engine is small, fast, reliable, and does not need a server to work. And, if needed, multiple applications may work with same SQLite database, optionally, using filesystem sharing services. However, file sharing option is not always available and reliable in certain conditions. In this paper, we propose a server for SQLite database. This server will be using HTTP as communication protocol. To enable multiuser application, this server will be multithreaded. However, access to the database file will be synchronized to help prevent database corruption. And, as data-interchange format, JSON will be used. We also run several tests to make sure that proposed server is usable. Test results show that the database file is not corrupted, while still maintain acceptable performance.

Smart mobile attendance system using voice recognition and fingerprint on smartphone

The attendance system has been known for a long time, ranging from manual system to automated and complicated system such as attendance system using biometrics. All those attendance system have several weakness, especially to control of employees who work outside the office. In this paper we introduced a attendance system that can be used to record the attendance of employees who are duty outside the building. Our system is also integrated with payroll system that make accounting department can easily calculate and report the salary included the overtime cost. The proposed attendance system used smartphone to verify the employee. The system provide two options for doing verification, such as fingerprint and voice recognition. In this research, we find that fingerprint verification has false positive 95% and the false negative of voice recognition is 5.88%.

Software size measurement of knowledge management portal with use case point

Knowledge Management portal is a system to support Knowledge Management process, in order to create, capture, develop, share, reuse and optimize the knowledge and particularly in Bina Nusantara University which has implemented Knowledge Management System (KMS) since 2002. However, this KMS need to be measured in order to know how better this KMS in term of the software size. The BINUS KMS will be measured in term of their software size in functionality perspective with use case point method. This metric of KMS will be used by management to know how better the software size, complexity level and effort to development in numbering. Measurement of software size with software metric such as Use Case Point upon use case diagram for BINUS knowledge Management Portal shows that the project has medium software size with score Use Case Point (UCP) = 108.56 and has estimate effort will be developed in 2,064 hours (or in 258 days or 51.6 weeks or 12.9 months) and has development cost for 516,000,000.00 rupiah (Indonesian currency). Use Case Point, estimate effort and project value will powerful to help management in order to make decision regarding the implementation of IT software project development in term of time, money and people.

Recent Trends in Nanotechnology and Materials Science

This research focused on studying the effects of a surface microstructure on S45C carbon steel using different pH values of electroless Ni-P plating. Meanwhile, the authors make an effort to improve the surface hardness and wear resistance of S45C steels through various heat treatments. The experimental results show that the specimens using acid and alkaline baths of pH5 and pH8 resulted in maximum hardness; the hardness values were the HV0.05 701 and HV0.05 803, respectively. Moreover, pH5 and pH8 of Ni-P deposition after 350 and 300 C and soaked for 1 h heat treatment, in which the highest hardness appeared, were HV0.05 1027 and HV0.05 1066, respectively. The specimens underwent the main precipitate phase of Ni3P after heat treatment. Due to precipitation, strengthening of the Ni3P phase increased the surface hardness of specimens after heat treatment; thus, the wear depth was decreased and wear resistance was enhanced. The optimal wear depth (2.738 lm) and (2.923 lm) appeared in Ni-P deposition by pH5 and pH8 after 350 and 300 C and soaked for 1 h heat treatment, respectively.

Bresenham Algorithm: Implementation and Analysis in Raster Shape

One of the most important aspect that have to solve in raster objects is to describe the structure of the individual objects and their coordinate locations within the scene. We required to implement the graphics output primitives. The Output primitives are very important since the performance of the graphics depend on the Primitives. Point positions and straight-line segments are the simplest geometric primitives. We focus on these parts in this research. In this paper we will implement and analysis how accurate and efficient raster line-generating algorithm, develop by Bresenham, that uses only incremental integer calculations. The implementation will be expanded to display circles and other curves. The analysis will be focus on numerical results, error produced, computation speed, and display. The language that used in this implementation is C++ with OpenGL.
