This paper presented the concept of developing a customized software testing process for software engineering in Shared Banking Services (SBS) System on one developed banking system in Malaysia. Software testing is one of the main activities in software development life cycle. This process consists of a few activities, which includes developing test plan and strategy, test design, test execution and evaluation of test result. However, a customized testing process is required for a specific domain in order to ensure the correctness and completeness of the test result. This project proposed a customized software testing process for Shared Banking Services (SBS) system and the study was conducted in order to identify the specific modules in SBS and its characteristics which differentiate it from other software applications. Besides that, two testing methodologies, which are RUP Test Discipline and Systematic Test and Evaluation Process (STEP), were compared based on criteria such as main activities, roles and responsibilities, artifacts and level of testing. The comparison result was then map to the characteristic of SBS to produce the proposed software testing process for SBS.
本文介绍了在马来西亚一个发达的银行系统上为共享银行服务(SBS)系统的软件工程开发定制软件测试过程的概念。软件测试是软件开发生命周期中的主要活动之一。这个过程由几个活动组成,包括开发测试计划和策略、测试设计、测试执行和测试结果的评估。然而,为了确保测试结果的正确性和完整性,需要为特定领域定制测试过程。本项目为共享银行服务(SBS)系统提出了一个定制的软件测试流程,并进行了研究,以确定SBS中的具体模块及其区别于其他软件应用程序的特征。除此之外,两种测试方法,即RUP测试规程和系统测试和评估过程(STEP),基于诸如主要活动、角色和职责、工件和测试级别等标准进行了比较。然后将比较结果映射到SBS的特性,从而产生SBS的软件测试过程。

A monolithically microwave integrated circuit (MMIC) variable active filter is presented for obtaining a small size variable bandpass filter with high selectivity at microwave frequencies. Variable active filter have been designed in BICMOS technology and used Advanced Design system (ADS) software for Design and simulation circuits. It is controllable for both quality factor Q, varying from 55 to 85, and a center frequency wider than 700MHz at the 2GHz band. Achieved Gain above 20dB from 1.65–2.35GHz. We used active input and output impedance matching. This will be a key device in the future development of frequency variable equipment.

Electrical steel is a key material for power apparatus in electric home appliances, industrial machinery and transport equipment. Specifically, they are used as cores in transformers, generators and motors, efficiently converting magnetic energy into electricity. The magnetic properties of steel laminations need to be precisely estimated in order to design an accurate electrical machine. In this study, two types of magnetic materials, grain-oriented and non-oriented electrical steel were used. Measurements were performed for vertical and horizontal arrangements of one-dimensional magnetizing system at the frequency of 50 Hz. The magnetic properties were principally investigated by developing the magnetizing system, constructed by two laminated C-cores with copper winding in excitation mode. The most important quantities in characterizing the magnetic materials are the magnetic field strength, H, and magnetic flux density, B. Results obtained indicate that different core arrangement influences the detected field strength. The results also show that the magnetic properties of grain-oriented are better compared to non-oriented steel.
电工钢是家用电器、工业机械和运输设备中动力器件的关键材料。具体来说,它们被用作变压器、发电机和电动机的铁芯,有效地将磁能转化为电能。为了设计精确的电机,需要精确地估计钢片的磁性能。本研究采用了两种磁性材料:晶粒取向和无取向电工钢。在50 Hz的频率下,对一维磁化系统的垂直和水平布置进行了测量。主要通过开发由两个层压c型铁芯和铜绕组在励磁模式下构成的磁化系统来研究磁性能。表征磁性材料的最重要的量是磁场强度H和磁通密度b。结果表明,不同的磁芯排列方式会影响检测到的磁场强度。结果还表明,晶粒取向钢的磁性能优于无取向钢。

This paper presents the classification of thumbprint using Artificial Neural Network (ANN). The ANN technique is conducted in order to improve the minutia extraction techniques. The classification of thumbprint is used in order to match the person's identification and train the data by using ANN. The data of thumbprint is taken from five different people. For each person, 30 thumbprint data is taken. All the data will be the input for artificial neural network for learning purposes. All the data will be adjusted using Corel. Then by using Matlab software, the data is trained and tested according to the artificial neural network program. This is to ensure that the output is matched with the input data. The result will be shown in the graph to identify whether the system is sufficient for training the thumbprint data. It can also be used for person identification. Therefore, the result shows that the system is accurate in training the data.

This paper evaluates and compares mobile ad hoc network (MANET) routing protocols for wireless sensor network (WSN). It focuses and compares the performance analysis based on Quality of Service (QoS) factors on the throughput and delay between Ad Hoc on Demand Distance Vector (AODV) and Temporary Ordered Routing Algorithm (TORA) protocols for mesh network with a single source. Ad Hoc on Demand Distance Vector is a reactive protocol and Temporary Ordered Routing Algorithm is on-demand reactive protocol which is the hybrid protocol. Previous research did shown that AODV is better than TORA for a larger nodes that is more than 30 nodes an some says that TORA is better for smaller nodes environment. In wireless ad hoc network, the nodes must be able to interconnect each other to establish the link or connection from source to the destination. The results show that AODV outperformed TORA in the throughput but AODV had higher delay than TORA. After the analysis has been done, this paper shows that AODV outperforms TORA in the wireless sensor network only with a single source and destination which less than 30 nodes in a network.
本文对无线传感器网络(WSN)中的移动自组网(MANET)路由协议进行了评价和比较。重点比较了单源网状网络中基于服务质量(QoS)因素的自组织按需距离矢量(AODV)协议和临时有序路由算法(TORA)协议的吞吐量和延迟性能分析。Ad Hoc按需距离矢量是一种反应性协议,而临时有序路由算法是按需反应性协议,是一种混合协议。先前的研究确实表明,对于大于30个节点的较大节点,AODV优于TORA,而有些人认为TORA更适合较小节点的环境。在无线自组织网络中,节点之间必须能够相互连接,以建立从源到目的的链路或连接。结果表明,AODV算法在吞吐量上优于TORA算法,但AODV算法的时延高于TORA算法。分析表明,在单源单目的无线传感器网络中,AODV算法优于TORA算法,且网络中节点数小于30个。

After the analysis has been done, this paper shows that AODV outperforms TORA in the wireless sensor network only with a single source and destination which less than 30 nodes in a network.","PeriodicalId":346890,"journal":{"name":"2011 IEEE International Conference on System Engineering and Technology","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131102626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A Doherty Amplifier operating at 2.4 GHz and a supply voltage of 2.5–3V is determined in this paper. The amplifier was designed in the Triquent GaAs process using the ADS software package. Simulation results show high output power and good power gain linearity up to the 3dB compression point. The results also show good 2nd and 3rd harmonic suppression.
