Heart monitoring system is a device to carry out electrocardiogram (ECG) test. It can diagnose human's heart either in normal or abnormal condition based on ECG analysis. However, most of the current ECG device is bulky, expensive and lack of a user-friendly graphical user interface (GUI) for user interaction. This paper describes an on-board GUI design based on capacitive touch-screen Liquid Crystal Display (LCD) display. It is integrated with the in-house design of ECG processing unit and arrhythmia classifier to form a complete System-on-Chip (SoC) based arrhythmia detector. The whole system is implemented on the Altera Video and Embedded Evaluation Kit with Multi-Touch (VEEK-MT) FPGA development board. The touch screen GUI acts as a front-end menu to capture user input and retrieve the offline ECG data stored in external SD card, as well as back-end result display in terms of arrhythmia classification result, ECG raw signal display, and R-R interval. Prototyping result shows that this system is light-weight, cost-effective and suitable to be user for different groups of user according to their knowledge background, including patient, nurse, physician and cardiologist.

WiMAX base stations are deployed in cellular network to increase the coverage area and capacity. Inter cell interference (ICI) is a major problem in cellular network. Different frequency planning techniques are proposed to handle the ICI effect such as frequency reuse of one (FR-of-1) and fractional frequency reuse (FFR). In this paper, these two types of network deployments are implemented, analyzed, and compared in a grid of 19 base stations, where band adaptive modulation and coding (band-AMC) is used in each cell. Users are randomly distributed in the target cell, and their resource and burst profile selection are determined based on the reported signal to interference plus-noise ratio (SINR). The simulation results proved that FFR shows better performance than FR-of-1 in terms of variety of metrics. FFR enhance the number of served users and resource utilization to 96.42 %, compared to FR-of-1 where only 77.77 % of resources are exploited. The data rate has been increased to 8.280 Mbps under FFR, whereas in FR-of-1 it reaches to 7.277 Mbps. The spectral efficiency in FFR equals to 0.619 Mbps/Hz, whilst it increased to 0.977 Mbps/Hz in FR-of-1, since the latter exploits all the available bandwidth unlike FFR where part of the bandwidth is not used in each cell edge. This work reveals that FFR can enhance the performance of WiMAX base station in an interference environment more than that in FR-of-1, which makes FFR a strong competitor for deploying WiMAX base stations in such environment.

Harumanis or its scientific name as Mangifera indica is a popular mango in Malaysia due to its unique aroma and taste, despite its expensive price. The high demand for this mango and its potential in export has been the reason why this tropical fruit being a national agenda for the Malaysian government to classify it as the specialty fruit from Perlis (smallest state in Malaysia). As the sole university in Perlis, University of Malaysia Perlis (UniMAP) has taken the initiative to develop greenhouse specifically for Harumanis mango. To support this, a real-time greenhouse monitoring system has been proposed. The system was developed based on Wireless Sensor Networks technology which consists of three parts: sensing module, radio communication module and gateway module. This system is able to provide real time monitoring of the important factors in plant growth such as the carbon dioxide, temperature, humidity level in the greenhouse. The performance result shows that the temperature inside the greenhouse is slightly higher compared to the open field; which meets the crop requirements. At night, the greenhouse microclimate drops and equilibrates to the surrounding temperature and humidity. This condition ensures good flowering and fruiting of sweet and juicy mangoes.

Recent rapid progress in information and communication technologies has spurred the exponential surge in the demand for unlimited high-speed and ubiquitous broadband wireless access (BWA), resulting in severe congestion of the radio frequency (RF) spectrum and wireless traffic bottleneck. Visible-light communications (VLC) is poised to become a promising BWA candidate to resolve the existing “last mile” problems. In this paper, we propose and initiate the implementation of a low-cost portable VLC transceiver capable of indoor wireless communication and multimedia broadcasting, thus presenting an economical and cable-free solution to various multimedia applications. The proposed optical transceiver design is based upon the integration of the transmitter and receiver hardware and an interactive software module, and relies upon a microcontroller which forms the system hub to manage the data and process flows among the different block components. The interactive software module consists of a graphical user interface (GUI) and a data processing algorithm, in order to control file transmission and reception in various format and to enable realtime interaction and viewing of multimedia applications.

Wireless Sensor Networks (WSN) consists of sensor nodes for monitoring and reporting sensible changes on a field to a specific server. One of the applications of WSN is large area monitoring, where sensor nodes are placed in far fields with limited power sources. Due to the adhered reason, the energy consumption of sensor nodes is considered as one of the major challenge in WSN. Many factor in WSN contributes to energy consumption such as Medium Access Control protocol (MAC), the network topology, and routing protocol. With the variety of factors that affects the energy consumption in WSN; the challenge of optimizing WSN networks toward a low energy consumption is becoming a hard problem. In the literature many efforts are paid for designing, implementing, and improving protocols in terms of power consumption. However, few efforts are paid for optimizing the existing protocols and other network parameters toward a green technology. This paper focuses in WSN infrastructure and protocols optimization by introducing the Ichi Taguchi (Taguchi) optimization method. Taguchi method is used to predict the best design parameters to achieve optimal performance parameters. Moreover, Taguchi method is used to optimize the energy consumed by sensor nodes against network protocols and network topology design parameters. A simulation experiments are curried out on the discrete event simulator OMNET++ for the purposes of this research paper. The obtained results show the impact of the network protocols toward the energy consumption. Furthermore, a proposed network topology and protocols set is introduced, and compared against the existing once.

In recent researches, much emphasis has been placed in developing non-volatile memories as candidates for replacement of volatile memories. Apart from non-volatility, memristive devices also have high switching speed, low energy consumption, and small device size. In this article, a novel one-bit memory cell using two transmission gates and one memristor (2TG1M) is proposed. SPICE simulations were performed to compare energy requirements per one-bit memory cell between the proposed memory cell and the conventional volatile one-bit SRAM cell. Simulations show that the SRAM memory cell requires between 73.034 pJ and 12.433 nJ to retain logic information for 10 years, while the proposed memory cell requires less than 1 pJ to hold logic information for up to 10 years. The proposed memory cell is also simulated against the popular one transistor one memristor (1T1M) non-volatile memory cell to show faster switching speed by 1.5 times. This work concludes the advantages of the proposed 2TG1M nonvolatile memory cell against volatile memory in terms of energy requirements, and against non-volatile memory in terms of switching speed.

Vegetable oils from different type of sources may have a distinctive aroma and flavour. This work explored the ability of combining PEN3 and UV-Vis Spectrophotometer for aroma and volatiles analysis. Nine types of vegetable oils were characterized and classified into three categories based on aroma and volatiles absorption characteristics which are fresh, heated and used cooking oil. The results of PCA analysis showed a good separation among three groups of vegetable cooking oil. Data set from both PEN3 (e-nose) and UV-Vis Spectroscopy was subjected to Linear Discriminant Analysis. Our results propose that discriminant analysis provides a rapid, efficient and accurate study for multi-class classification difficulties. LDA is capable to provide 100.0% correct classification of original grouped cases. However, only 85.4% of un-known grouped cases are correctly classified.

Power Line Communication (PLC) is a potential infrastructure for Information and communication Technology (ICT) services provision. PLC is a technology that utilizes electrical power lines for high speed transmission of data, video, voice, et cetera. In an indoor environment, PLC can provide solutions for small offices and homes that have poor wireless coverage and provide high throughput and an inexpensive and easy-to-install Ethernet connection over powerlines. In this paper, we construct a real experiment to examine the performance of power line network adapters produced by the HomePlug AV standard using the Iperf tool. In addition, we explore commercially available equipment in an actual working environment. The impact of possible noise sources accrued from electrical appliances (chargers, AC Adapters, Fridge) and plug in conditions that the producer has not recommended have been examined simultaneously with data throughput analysis.

The radiation pattern of an adaptive array antenna can be optimised by manipulating the amplitude and phase excitation of the array elements. In this paper, different adaptive beamforming algorithms including minimum Mean-Square Error (MSE), power minimisation and maximum Signal to Interference-plus-Noise Ratio (SINR), are compared and discussed. The algorithms are applied to a 3-faceted adaptive array antenna. Simulation results show that the resulting radiation pattern with minimum MSE has higher directivity and lower sidelobe level compared to the other optimisation criteria, which allows the array to avoid more interference signals in a wireless communication system.

Automatic grading of oil palm fresh fruit bunch is desired. In this study, a capacitive sensing system was designed and developed for the purpose of grading oil palm fresh fruit bunch. In this method, oil palm fresh fruit bunch placed between capacitive plates as a dielectric material and then measure the resulting capacitance voltage. Experiments were carried out using oil palm bunches of Tenera variety. Ripe and unripe mature bunches tested with 100 kHz sinusoidal frequencies. Correlation of capacitive response observed to be linear to bunch weight and negative linear to bunch ripeness. This result suggest that this method be explored for automatic grading of oil palm fresh fruit bunch.
