Output from this application is a music sheet from midi music file chosen by user. User also can save and print the music sheet. This application success to create the music sheet from midi music file, but it still has limitation, for example is drawing the rest symbol. If there are so many rest symbols, application will draw from the rest symbol whose biggest value
DESAIN ETL DENGAN CONTOH KASUS PERGURUAN TINGGI
Get PDFData Warehouse for higher education as a paradigm for helping high management in order to make an effective and efficient strategic decisions based on reliable and trusted reports which is produced from Data Warehouse itself. Data Warehouse is not a software, hardware or tool but Data Warehouse is an environment where the transactional database is modelled in other view for decision making purposes. ETL (Extraction, Transformation and Loading) is a bridge to build Data Warehouse and transform data from transactional database. In every fact and dimension table will be inserted with fields which represent the construction merge loading as an ETL (Extraction, Transformation and Loading) extraction. ETL needs an ETL table and ETL process where ETL table as table connectivity between tables in OLTP database and tables in Data Warehouse and ETL process will transform data from table in OLTP database into Data Warehouse table based on ETL table. The extraction process will be run with a table database as differentiate ETL process and an ETL algorithm which will be run automatically in idle transactional process, along with daily transactional database backup when the information system are not used
PENGUKURAN KINERJA BEBERAPA SISTEM BASIS DATA RELASIONAL DENGAN KEMAMPUAN MENYIMPAN DATA BERFORMAT GML (GEOGRAPHY MARKUP LANGUAGE) YANG DAPAT DIGUNAKAN UNTUK MENDASARI APLIKASI-APLIKASI SISTEM INFORMASI GEOGRAFIS
Get PDFIf we want to represent spatial data to user using GIS (Geographical Information System) applications, we have 2 choices about the underlying database, that is general RDBMS (Relational Database Management System) for saving general spatial data (number, char, varchar, etc.), or saving spatial data in GML (Geography Markup Language) format. (GML is an another XML’s special vocabulary for spatial data.) If we choose GML for saving spatial data, we also have 2 choices, that is saving spatial data in XML Enabled Database (relational databases that can be use for saving XML data) or we can use Native XML Database (NXD), that is special databases that can be use for saving XML data. In this paper, we try to make performance comparison for several XML Enabled Database when we do GML’s CRUD (Create-Read-Update-Delete) operations to these databases. On the other side, we also want to see flexibility of XML Enabled Database from programmers view
PENGGUNAAN ALGORITMA NEWTON – RAPHSON UNTUK MEMBUAT SOFTWARE PENENTUAN DOSIS OBAT
Get PDFUSCPACK Software from University of Carolina is one of the pioneers of computerized drug dosage system. This software uses Bayesian method. The algorithm that used in this software is known as NPEM (Non Parametric Expectation Maximization). After knowing how USCPACK work, then we made new software that has the same use like USCPACK but with new algorithm that different from NPEM. These paper will describe the how to make the software based on NPAG algorithm.

IMAGE DATA CLASSIFICATION BY NFES-MODEL
Get PDFIn this paper, we propose an identification method of the land cover from remote sensing data with combining neuro-fuzzy and expert system. This combining then is called by Neuro-Fuzzy Expert System Model (NFES-Model). A Neural network (NN) is a part from neuro-fuzzy has the ability to recognize complex patterns, and classifies them into many desired classes. However, the neural network might produce misclassification. By adding fuzzy expert system into NN using geographic knowledge based, then misclassification can be decreased, with the result that improvement of classification result, compared with a neural network approximation
PEMBUATAN SYSTEM CORPORATE MESSENGER PADA JARINGAN LAN
Get PDFCorporate messenger is the one of the application that can be used for communication in a local area network. The backgrounds of this topic are needs of sending message process in the LAN. The messages which want to be presented are not only in a text format, but also can be in audio visual format. Computer client will connect to the server. When the connection has been established, the client continued the authentication and started sending message between client and server. Audio and video message sending can be done with peer to peer connection with entering the IP address first from remote user that we want to communicate with. The evaluation of this application was done by using 3 computers and as the result, we found that authentication process can work properly, sending text message was done properly and communication using audio can be heard clearly. In addition to video sending message, we could see directly in remote client. The average time to show the video on remote client is 3.771 seconds.
