The work was performed based on a complementary asymmetric split ring (CASR) unit cell to identify its resonance characteristic and relevant dispersion diagram at 5.9 GHz. By using this CASR singularly into a guided transmission line, electromagnetic energy coming from the source can be seen travel at its peak. Yet, the same CASR do not resonate well if its nearby region are placed with another smaller similar CASR dimensions. This can be solved by optimizing the unit cell to resonate at a wider bandgap and achieve a better dispersion diagram that do interfere with other modes The outcome of this approach can be well suited to act as an alternative electromagnetic shield or even a surface wave splitter.","PeriodicalId":410290,"journal":{"name":"2016 3rd International Conference on Electronic Design (ICED)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126788404","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 effects in the main focus on the atmospheric attenuation effects due the visibility and link range (length). Visibility is the main concern in utilizing the FSO communication system. The higher visibility, the longer transmission link. Hence, FSO performance could be enhanced and increased efficiency by using different wavelengths of laser beam. The conventions generally used wavelengths are 785 nm, 850 nm, and 1550 nm. The analysis result shows that the wavelength 1550 nm is better than 785 nm and 850 nm due to the less attenuation performance. Wavelength 1550 nm had improved 33%, 67%, 80% and 100% compared to the wavelength 850 nm and 785 nm due to the visibility and distance of 3 km, respectively. Higher wavelength able to thin out the attenuation effects on FSO links.

A Wireless Sensor Networks (WSN) technology is one of the powerful technologies that enable IoT objects to communicate with each other. Device-Free Localization (DFL) system exploits changes in radio signals across different environments aims to detect and track entities without requiring them to carry any additional RF devices or to be cooperatively participating with the localization process. This paper proposes a received signal strength indicator (RSSI) - based DFL system that can be used to detect human presence in an area of interest (AoI) using changes in signal strength measurements. The main objective of this paper is to design a DFL system that can be easily deployed and configured using IRIS mote from MEMSIC based on `plug and play' concept and operates in real time. The system is deployed in CEASTech's Research Room by using the IRIS mote as the communication module in the network. The principle behind this is that the human body and motion have strong impact on the signal strength of indoor wireless links being transmitted from a transmitter to one or more base stations by either shadowing or diffraction, or by scattering. Result shows that signal strength fluctuate by 3.97dBm and from 10 to 15dBm with the presence of stationary human and moving human respectively.","PeriodicalId":410290,"journal":{"name":"2016 3rd International Conference on Electronic Design (ICED)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122158426","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}

Hence, the design and implementation of networks-on-chip should be considering aspects of simplicity in design, bandwidth usage, delay and power consumption. In essence, adaptive technique is a potential routing algorithm for better performance in network-on-chip (NoC) in which have properties such as prevention of livelock, deadlock, and starvation. This paper employed survey to investigate the impact of deterministic routing algorithm that has degrade overall performance and deadlock happen due to the fixed direction to the destination.

This makes present system resource expensive and ineffectual, as overflowing, stinking dustbins become more of a problem than a solution.

An automatic micro-controlled stepper motor is implemented on the Michelson Interferometer to provide small micro displacement on the movable mirror and enable fringe shift. Through fringe visibility measurement, fringe shifting through micro-controlled stepper motor allows consistent and precise measurement. Analysis of fringe visibility was conducted on several samples etched with Hydrofluoric (HF) acid. The main fringe visibilities obtained after the silica glass were etched with HF ranged from 0.67-0.73. Fringe visibility of the silica glass samples increased when the time of etching of HF was reduced. Based on the results obtained the automatic fringe shift with micro-controlled stepper motor reduced human error and has better resolution in intensity measurement which allows fringe visibility to be measured more accurately. The fringe visibility analysis can also assist in surface profiling of other transparent and reflective thin films.","PeriodicalId":410290,"journal":{"name":"2016 3rd International Conference on Electronic Design (ICED)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132299078","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}
