The estimator equations are derived by manipulating the lognormal propagation model via maximum likelihood estimation method. In this paper, the path loss exponent and variability of fading parameters in indoor environment are assumed to be unknown. The performance of the estimators in predicting the path loss exponent, the variability of fading components and most importantly, the distance between the receiver and transmitter are analysed through simulations and the data obtained from RSS measurement in three indoor environments (an ideal and two natural fading environments). The simulation and measurement results show that the accuracy and precision of the estimators are highly dependent on the level of fading present in an environment, with higher accuracy in the estimators' performances found in fading environment with a low variability.","PeriodicalId":360454,"journal":{"name":"2016 International Conference on Computer and Communication Engineering (ICCCE)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133386846","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}

Low magnetic field detection is particularly important in tracking of magnetic markers in digestive tracks or blood vessels. The presence of magnetic fields' strength and direction can be detected by a device known as magnetometer. A magnetometer that is durable, room temperature operation and having non-movable components is chooses for this project. Traditional magnetometer tends to be bulky that hinders its inclusion into micro-scaled environment. This concern has brought the magnetometer into the trend of device miniaturization. Miniaturized magnetometer are usually fabricated using conventional microfabrication method particularly surface micromachining in which micro structures are built level by level starting from the surface of substrates upwards until completion of final structure. Besides time consuming, this method requires many consecutive steps in fabrication process and careful alignment of patterns on every layer which increase the complexity. The issue of miniaturization and complexity of conventional fabrication process has lead to this investigative research. The main objective of this research is to investigate and analyze the best and reliable micro coil for search coil magnetometer. Simulations and analysis for micro-scaled coil that is capable of detecting low magnetic field are done. The expected work include investigation on possible magnetometer of detecting low magnetic field, designing micro scale magnetometer, complete device fabrication processes, testing and characterization of the fabricated prototype device. Based on the results of simulation, a search coil magnetometer of 60µm thickness with spacing of 60µm and 30 turns was designed.","PeriodicalId":360454,"journal":{"name":"2016 International Conference on Computer and Communication Engineering (ICCCE)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134002399","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 main challenges of the deployment, where different network tiers share spectrum, is how users associate with the cells to achieve load balancing for improving system performance. The importance of joint metrics based cell association is stressed here, by combining channel gain and channel access as a single metric to maximize the spectral efficiency as well as achieve a balanced load among the network tiers. The load balancing performance of the hybrid channel gain and access scheme was found to be midway when compared with the extreme cell association schemes: conventional reference signal receive power (RSRP) and the high bias RSRP. Although the cell edge users of the proposed scheme have the worst spectral efficiency performance compared to the interference-aware cell selection schemes considered in this work, the cell centre users exhibit the best spectral efficiency performance.","PeriodicalId":360454,"journal":{"name":"2016 International Conference on Computer and Communication Engineering (ICCCE)","volume":"274 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124918681","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}

In addition, we also introduce a new cache replacement algorithm PDE (Predictive Dead-time Elimination), based on a compound measurement of data cached with the second exponential smoothing technique.

The Coupling coefficient of 3-dB fused directional fiber coupler was determined based on perturbation method and coupling mode. A good agreement between theoretical purposed and empirical coupling coefficient from experimental result was reported. The coupling coefficient between the waveguides is significantly induced by the distance of axial separation between parallel fibers and geometrical coupling region. It is exponentially decreases by increasing separation between fibers.

The loss of human body, especially the upper and lower limbs will limit the daily activities of patient in many ways. There were many studies that had been done previously in developing prostheses which were simpler in the forms than human limb. However, the performance of these units was mostly unnatural and is damped by constraint in the model of the limbs. In this paper, the development of thumb training system that allows the measurement of electromyography (EMG) signal when the thumb is flexed at different angles with varying force is discussed. The parameters are then possible to be used with conjunction of Hill's muscle model to develop a more precise model of the thumb. The platform also features several adjustments so as to suit various size of human hands. The result from EMG measurement from the system shows that the system is able to characterize the EMG signal of thumb at different pose and force.","PeriodicalId":360454,"journal":{"name":"2016 International Conference on Computer and Communication Engineering (ICCCE)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122942299","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}

By inserting an optimized triangular slits and multi-slotted ground plane, the antenna produced a high fractional bandwidth of 120% with operating bandwidth from 3.1 GHz to 12.33 GHz. The antenna has very small size as 12x18 mm2. Yet, it still can produce very wide operating bandwidth. The modified planar antenna fulfills the requirement for ultra-wideband (UWB) applications which need operating bandwidth from 3.1 GHz to 10.6 GHz. The significant parameters of the proposed antenna are defined clearly in this paper. Simulated results are observes and analyzed.
