One of them is scintillation. Scintillation arises from atmospheric refractive index discontinuities and resulting in random fades and fluctuation of the received signals amplitude about a mean level. This is caused by small scale loopholes in the transmission path with time. It is an important source of degradation especially on low availability satellite communications systems operating at frequencies above 10GHz. Scintillation occurs continually, nonetheless whether the sky is clear or rainy. Many prediction models have been proposed to predict the tropospheric scintillation which is the fast fluctuations on line of site links on earth-space paths at different frequencies. Most of them can predict tropospheric scintillation from 7 GHz to 20 GHz. All of them have been developed based on scintillation data collected from temperate climate. But tropical countries have different patterns of climate compared to the four seasons' countries. Their climate is mainly uniform temperature, high humidity and heavy rainfall. Up to now, there have been very few researches done on scintillation fit for tropical countries. Hence, scintillation models need to be investigated based on scintillation data measured in tropical country. The purpose of this paper is to investigate on which models are suitable for Malaysia's tropical climate. This paper will also present a complete analysis of all prediction models. It highlights their strengths and limitations and also focuses their suitability to tropical climate.","PeriodicalId":376337,"journal":{"name":"2011 4th International Conference on Mechatronics (ICOM)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128148772","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}

Responding to the issue, this paper focuses on development of an elevator group controller based on fuzzy algorithm. By introducing a fuzzy controller in an elevator system, this project is developed to manage the required passenger traffic density keeping passenger waiting times within reasonable limits. To increase the performance of the elevator group three major linguistic variables are introduced within a set of fuzzy rules. These include the average waiting time (AWT), power consumption (PC), and floor traffic (FT). When the passenger traffic is high, the low fuzzy control values reduce the importance of priority of floors rather the estimated arrival time is to be minimized. The simulation was accomplished to check the priority of fuzzy system graphically while the actual prototype of elevator system is programmed by PIC device as a controller. As a result a set of fuzzy rules was drawn based on practical considerations; mainly minimization of waiting time and energy consumption. When a few hall requests are registered, the elevator controller will decide which one of the elevators will serve which of the incoming hall requests. In order to manifest the work with actual elevator service, a computer simulation of a four-cars-elevator controller in a twenty storied building is accomplished by using MATLAB™ fuzzy logic toolbox and implements the prototype experimental model.","PeriodicalId":376337,"journal":{"name":"2011 4th International Conference on Mechatronics (ICOM)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114911499","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 system is developed to overcome the discrepancy from human vision and illumination changes. This paper proposes shape-based vision algorithm, a hierarchical template-matching approach that implemented in flexible manufacturing system to verify the quality of engraved image. Color and gray scale charged couple device (CCD) cameras are used to acquire engraved image for different kind of environment. The engraved image is preprocessed using image processing technique. Region of interest (ROI) is then selected and digitized into gray level to extract the contour of the object using segmentation technique. The extracted contour is used as template for object recognition during matching process. Several objects are engraved on the acrylic souvenir bases with different color background to test the algorithm. This experiment result shows that the algorithm works better with detection rate of 100% and matching accuracy of more than 98%. The approach can be applied in packaging, pharmacy, education, medical or any other areas which apply shape in their application.","PeriodicalId":376337,"journal":{"name":"2011 4th International Conference on Mechatronics (ICOM)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128035412","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}

We were aiming at generating a smooth and natural cooperative transfers performed by a human-robot system. Prior to the development of such system, characteristics for smooth and natural cooperative object transfer in a human-human system were investigated. Specifically, we focused on the information exchange between subjects during execution of the cooperative task. We have investigated the effect of perceiving different part of the object as a means for exchanging information between subjects. We also considered the importance of having information of cooperative task initiation signal and targets position to the task smoothness (mediolateral and anteroposterior direction). The results indicated that perceiving the Centre part of the experimental object produced more frequent smooth and natural cooperative task executed in mediolateral direction but not for the task in anteroposterior direction. Also, regardless of Centre or End case, cooperative motion smoothness increased when time of initiation and target position and was available to both subjects. Those characteristics will be considered in designing the human-robot system.","PeriodicalId":376337,"journal":{"name":"2011 4th International Conference on Mechatronics (ICOM)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116549794","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}
