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.","PeriodicalId":143806,"journal":{"name":"2014 2nd International Conference on Electronic Design (ICED)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115721102","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}

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.","PeriodicalId":143806,"journal":{"name":"2014 2nd International Conference on Electronic Design (ICED)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124483073","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}

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.","PeriodicalId":143806,"journal":{"name":"2014 2nd International Conference on Electronic Design (ICED)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122522144","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}

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.","PeriodicalId":143806,"journal":{"name":"2014 2nd International Conference on Electronic Design (ICED)","volume":"310 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115914343","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}

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.","PeriodicalId":143806,"journal":{"name":"2014 2nd International Conference on Electronic Design (ICED)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122304846","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}
