This project presents the development of patellar reflex measurement system using Linear Variable Differential Transformer (LVDT). The measurement system is based on knee reflection as the patellar tendon was tapped with tendon hammer. The system proposed capable to detect four graded levels of Deep Tendon Reflex (DTR) which are zero absent, hypoactive (underactive), normal, and hyperactive (overactive)...
An alternative algorithm to Pulse Width Modulation (PWM) for pulsed activation of solenoid valves for applying chemicals through agricultural sprayer nozzles is presented. Solenoid valves attached to individual spray nozzles on a modified EMDEK tractor-mounted sprayer system are activated by electronic pulsation to vary the application rate of agricultural chemicals, varying the output by location...
The distributive nature of ontology development has led to a large number of ontologies covering overlapping domains, which needs to be merged and aligned to one another for their successful sharing and re-use. There are many ontology engineering techniques available but it has been seen that the current approaches of matching, merging and aligning suffer from a number of problems and these techniques...
The residue number system (RNS) is a carry-free number system which can support parallel and high-speed arithmetic. In this paper, efficient and simple designs of forward and reverse converters for the new radix-r moduli set {r2n, rn - 1} are presented. This moduli set contains well-formed moduli which can result in fast RNS arithmetic and efficient forward and reverse conversion. In comparison with...
The proposed scheme is an extension from Set Partitioning In Hierarchical Trees (SPIHT) algorithm. It combines the SPIHT algorithm with Slepian-Wolf (SW) theorem. In most of the video coding scheme that adapted the Slepian-Wolf or Wyner-Ziv (WZ) theorem, a feedback channel is usually incorporated to correct errors that occurred at the decoder side. The used of feedback is a big drawback in system...
In this paper we design and evaluate the performance of a JPEG-based multiple description image coder. We add zeros to DCT transformed of the original image to create an over-sampled image, and split the over-sampled image into two partitions by separating image blocks. For each partition we use a baseline JPEG coder. In order to evaluate the system performance, we assume that encoded bit-streams...
Image segmentation is a critical stage in many computer vision and image process applications. Accurate segmentation of medical images is very essential in Medical applications but it is very difficult job due to noise and in homogeneity. Fuzzy C-Mean (FCM) is one of the most popular Medical image clustering methods. We noticed that for some images, FCM is sensitive to initialization of centre of...
Software risk management is the practice of assessing and controlling risks that affects the software projects, process or products. Those who practice risk management agreed that it is must be performed regularly throughout the lifecycle of a software system. But one of the main challenges in dealing with software risks is to provide a visual risk assessment tool. This paper intends to report on...
Sonar data from the UCI Machine Learning Repository database has large input features. It is known that too many input features have high tendency for redundant data and difficult to be handled by Multilayer Perceptron (MLP).This paper proposes the integration between MLP and circle-segments method for material detection based on sonar data. Circle-segments is a data visualization methods useful for...
Artificial Neural Network (ANN) has been shown to be a robust tool for intelligent recognition. In every intelligent recognition task, the first dilemma would be the correct size of training data, since too few is definitely not sufficient while too many may lead to over training problem. This paper presents a study on the dimensionality of training data for a Multi-layer Perceptron (MLP) neural network...
This paper presents a research about the software system to calculate cost estimation in plastic injection mould manufacturing which is named as mold cost estimation calculator (MCEC). The objectives for MCEC is to optimize the cost estimation problems in plastic injection mould, assists industrial practitioner in estimating budget for manufacturing and assists for teaching purposes. There are three...
The rapid-changing consumer market has encouraged many product designers to create products that are closely related to consumer’s psychological needs. Several methods have been introduced to aid such design goal but Kansei Engineering (KE) is the most notable tool that helps translates human feelings into design parameters. With the aid of advanced computer technologies, various computerised KE systems...
The control system of a commercial sprayer was modified for variable-rate control of 12 individual solenoid shut off valves spaced 0.5 m apart on a sprayer boom. The variable-rate control system consisted of pulse width modulation (PWM) solenoids, a by pass control valve, and nozzle control system interfaced to a computer. An algorithm was developed to vary application rate across the booms with computing...
An apparent constraint on the Network Simulator (NS-2) is that it does not currently allow for dynamic interaction between itself and the users while a network simulation process is running. Having realized the advantages of NS, it is interesting to investigate the feasibility to develop a mechanism that would enable the dynamic interaction between the users and NS itself. This paper is focused on...
Electronic Number Mapping (ENUM) is a suite of protocols to unify the telephone numbering system E.164 with the Internet addressing system DNS by using an indirect lookup method. This will generate NAPTR records. These records are stored at a DNS database. IETF started the ENUM Working Group in 1999. The group formed the standards of the basic protocol of ENUM as in RFC291 in the year 2000 and improved...
The focus of this paper is on the implementation of Bluetooth as a tool to provide m-advertising (mobile advertising). The paper attempts to introduce the implementation of Bluetooth m-advertising system based on user-driven concept using pull-based approach. User-driven concept gives flexibility to end users to select the preferred advertisements from the server while pull-based m-advertising provides...
