This paper models the signal strength measurements at 2.4 GHz in indoor environment. The received signal strength indicator (RSSI) measurement is used to investigate the wireless network coverage in a real office environment where obstacles such as furniture are present. From this experiment, a mapping is created to determine the suitable positions for a short range sensor nodes deployment for sensing humidity, temperature, human movement, etc. The purpose is to evaluate the suitable area for WSN deployments using RF signal and to minimize the number of sensor nodes required for data gathering and monitoring applications. The result shows that through adequate planning of WSN nodes, good radio coverage and efficient monitoring can be achieved for greener building.

This paper focus on increase the efficiency power in free space optical communication by using new dual diffuser modulation (DDM) technique. Atmospheric turbulence effect which is considering on scintillation phenomenon is considered in this case study. Phase screen diffuser which will be placed at transmitter create `new' beam wave to propagate through turbulence more efficiently. This technique uses two transmitter and differential mode detection at the receiver. The result shows that at 622Mbps data bit rate the DDM technique can detect more weak signal approximately -15dBm and with assume fix propagation distance at 1km the power received can achieved -26dBm. As the result, DDM technique improved the efficiency power if compare to conventional technique that apply intensity modulation - direct detection of On Off Keying (IM-DD OOK).

Current studies document the effectiveness of multi-sensing technique implementation to mimic or to complement human senses. This work demonstrated the successful application of multi-sensing techniques such electronic tongue (e-tongue), electronic nose (e-nose) and Fourier Transform Infrared Spectroscopy (FTIR). The fusion of these modalities enhance the classification of pure Tualang honey using Linear Discriminant Analysis (LDA), Probabilistic Neural Network (PNN), Support Vector Machine (SVM) and k-Nearest Neighbour (KNN). KNN and PNN are able to classify between pure and adulterated honey samples, outperform LDA and SVM. By performing data fusion, SVM and LDA classifier can achieved more than 80% accuracy, while KNN and PNN obtained greater precision, up to 96% correct classification. The findings confirmed that, multi-sensing technique; either KNN or PNN was significantly superior compared to SVM and LDA classification methods. Thus, both analyses are able to discriminate between pure and adulterated honey.

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.

Managing and allocating available resources are vital in communication networks in order to attain a network design objective while keeping great satisfaction in quality of service (QoS) for all users. Resource allocation in multi-cell system can be described as maximizing of a system utility by allocating transmits power among users and spatial directions. Different resource scheduling algorithms also have been addressed to handle the resource allocation among users. Hence, this study provides an optimization framework for downlink resource allocation in a single cell with multi user system. The framework will then be extended for multi-cell system. The structure of optimal resource allocation is derived based on Taguchi's method. An initial simulation study has been carried out using OMNeT++ simulator. Three performance criteria are measured which are MAC throughput and delay of the system, and also the mean opinion score (MOS) for VoIP traffic application.

All over the world, the existing spectrum is already been saturated with ever increasing demand. Every day huge number of users is joined to the existing fixed band frequency but the bandwidth is not increasing. To solve this issue the cognitive radio is the best choice. Spectrum or white space detection is an essential and very important issue in cognitive radio communication. The aim of channel detection is to find out efficiently the presence or absence of primary or licensed frequency. In this paper, we have developed a Libelium Waspmote sensor based cognitive radio detection scheme which is very easy to use, energy and cost effective. The reason for selecting this type of sensor is it supports IEEE 802.11 b/g and the Tx/Rx antenna transmission and reception sensitivity can be changed by the software. It can scan the available channel resource within its range and can store the data files. Also the security of this type of sensor supports the highest level of wireless security that is Wireless Protected Access V2 or WPA2. It is Windows based which is very common worldwide. The application runs in background without interrupting the PC/Laptop users. It is able to find efficient spectrum hole (Ideal channel) for a secondary or cognitive user to use the primary or licensed band without interrupting the primary user.

The work in this paper is dedicated to present and experiment a fully automatic face recognition approach based on exploiting the distinctive traits of 3D facial scans. We aim to present a recognition approach operates with fully and partial facial scans (missing facial parts). A region based approach for registration and recognition processes is adopted to offer robust faces matching against facial expression and pose variations. An average nose model was constructed in this work via procrustes analysis concept for registration purpose. The nose region for both training and testing facial scans is detected using cascade filtering scheme of the extracted local descriptors (Distance to Local Plan and shape index). Finally, the similarity measure between faces is computed based on Iterative Closest Point (ICP) method. The effectiveness of the proposed approach has been evaluated on GAVADB 3D face database which consists of both frontal and partial facial scans. The experimental results showed, that nose region has been detected accurately with success rate 98% for facial scans having natural expression and frontal pose, which leads to achieve high recognition rates of the faces. The experiments have demonstrate that nose region based detector capable to operates significantly with partial facial scans and thus achieves accuracy about (5.5 mm) for nose tip location.

An average nose model was constructed in this work via procrustes analysis concept for registration purpose. The nose region for both training and testing facial scans is detected using cascade filtering scheme of the extracted local descriptors (Distance to Local Plan and shape index). Finally, the similarity measure between faces is computed based on Iterative Closest Point (ICP) method. The effectiveness of the proposed approach has been evaluated on GAVADB 3D face database which consists of both frontal and partial facial scans. The experimental results showed, that nose region has been detected accurately with success rate 98% for facial scans having natural expression and frontal pose, which leads to achieve high recognition rates of the faces. The experiments have demonstrate that nose region based detector capable to operates significantly with partial facial scans and thus achieves accuracy about (5.5 mm) for nose tip location.","PeriodicalId":143806,"journal":{"name":"2014 2nd International Conference on Electronic Design (ICED)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129463924","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}
