Software verification and validation is a critical phase in software development projects. But unfortunately in many software development projects, software verification and validation rarely gets sufficient attention. Lack of attention is partly due to the assumption that the software verification & validation is not a priority and there for only limited resources can be allocated. This paper presents the result of study in using forecasting analysis model to assist software test strategy preparation. This study applies forecasting analysis to accumulation of individual transaction data that have been got before the system is tested. Those forecasting results are used as comparison tool to compare with the transaction data generated by system which is being tested. This study use subsidized fuel consumption monitoring system as a case study to apply the forecasting model. Test results on the case study, with some limitations, show that forecasting analysis and simulation model can be used as one of inputs to software verification & validation strategy preparation. © 2012 IEEE.

There are always new challenges in the extraction of object (entity) relations contained in unstructured or semi structured text documents found in the Internet, due to the volume of the documents, the evolution of the text language, and the fast Internet growth. In this paper, the authors present the description and the experimental results of a novel role based approach in mining the entities and its relations. The proposed method defines a new concept of entity relationship which treat entities relation as the relation of the main object and its supporting object. The relation between these objects are extracted through pattern learning process that utilize the Indonesia WordNet as an external knowledge. Based on the performance evaluation of the proposed method, it can be confirmed that it is feasible to apply the method in the area. The feasibility of the method is measured by the accuracy of the extraction process in 10 experiments. The average F-score values for the experiments are 0.895 and 0.795 in main object extraction and supporting object extraction respectively. © 2005 - 2015 JATIT & LLS. All rights reserved.

For effective identification of objects, Radio Frequency Identification (RFID) is used in miscellaneous activities. In recent times, RFID is also used for positioning purposes. We show a scenario of wireless propagation in free space observed by up to eight antennas with different polarization located in different positions. In this way, the polarization and diagram radiation of the antennas will play a significant role in producing electromagnetic field in the region. In the second case, the effects of disturbances in form of metallic boxes are studied. The determination of the position is carried out by fingerprinting procedure.

Bandpass filters play a significant role in wireless communication systems. Transmitted and received signals have to be filtered at a certain center frequency with a specific bandwidth. In designing of microstrip filters, the first step is to carry out an approximated calculation based on using of concentrated components like inductors and capacitors. After getting the specifications required, we realized the filter structure with the parallel-coupled technique. Experimental verification gives comparison, how close the theoretical results and measurements look like.

The classification of residential defects (case study: Citra Garden Residence in Indonesia) was studied. This study aims to more satisfied customers. The study begins with the literature review to formulate the classification of house defects. Then classify the defect of house into two, namely the classification of house defects based on period of post hand over, and the classification of house defects based on category of the defects. Further studies followed by dividing the classification of house defects based on period of post-hand over into three parts, namely before hand over period (inviting time), hand over period, and post-hand over period. The next step is to check the complaint report from the customer service in Citra Garden Residence in Indonesia to quantificate the defects of the house. The classification of house defects based on category of the defects divided into two, namely structural defect (minor, moderate, serious), and nonstructural defect (minor, moderate, serious). The next step is also to check the complaint report from the customer service in Citra Garden Residence in Indonesia to quantificate the defects of the house.The results show that complaint hand over in the level minor defect is the highest complaint. Complaint in the serious defect is the lowest complaint. © (2014) Trans Tech Publications, Switzerland.
