The design of this new way approached is implemented using Cadence OrCAD Capture CIS 15.7 software and hardware construction and troubleshooting. From the previous research, it has been found that for a sensor input range of 1.1 to 1.3 kilo ohms, an output range of −100 to +100 millivolts is obtained. The design for filtering stage used the first order passive low pass filter to accommodate the stress signal frequency for 0.4Hz. Besides the design also focus to boost up the low voltage input of 108.6mV–(−100mV) to 0V–5V output voltage. Its involved low pass filter, voltage follower and linearization stages. The result indicates discrepancy within 4.5% and 3.7% were found between the simulation and experimental results for voltage follower after filtering and linearization circuit respectively, on the average. This development allowed stress measurement with relatively high precision and accuracy.","PeriodicalId":178300,"journal":{"name":"2010 2nd International Conference on Electronic Computer Technology","volume":"99 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120886180","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}

It also studies the effect of using skin region segmentation for face detection. Range of 1σ from the skin color mean in CbCr channel is used to segment the skin region, instead of using Mahalanobis distance. Ranges more than 1σ should be avoided, as they will give precision and recall worse than that of 1σ. Using skin color region to segment the face candidate does not necessarily reduce the detection time, and it is not always true that the detection rate of the detector will be improved. In most of the tests, the precision does not fall much when we increase the range. This means that the performance of the detector is ‘buffered’ by the AdaBoost-based detector.","PeriodicalId":178300,"journal":{"name":"2010 2nd International Conference on Electronic Computer Technology","volume":"168 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123274813","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}

Actuator saturation is one the practical problem in control of various systems. Even it might cause instability. In this article we describe different problems that are caused by saturation. After that a method is proposed to remedy the effect of it. In the proposed method this problem is solved by decreasing the band width of the controller. In order to accomplish this, a supervisory control is employed which uses artificial immune algorithm to adjust the proper forward path gain and then we compare the result with fuzzy supervisor. As you will see immune supervisor has better result in compare with fuzzy model. Recently, the biological immune system arouses researchers' interest since it has several useful mechanisms which can be used for information processing. In this paper, an improved artificial immune algorithm is presented which is used in the design approach of a supervisory loop.","PeriodicalId":178300,"journal":{"name":"2010 2nd International Conference on Electronic Computer Technology","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130113498","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}

According to the characteristic of current path planning methods and the path planning of unmanned aerial vehicle, the paper established an index system which was used to evaluate path planning methods. Based on this, it had an evaluation of path planning method by using grey clustering evaluation method with improved index weigh coefficient, and then explained the application method by combing with a example. From the result of example, it can be seen that using path planning method's grey clustering evaluation with improved index weigh coefficient can effectively reduce the influence of subjective factor and get a more objective result, furthermore it also provides a effective way to comprehensively and systematically evaluate path planning methods. It can provide decision-making basis for selecting and optimizing path planning method too.","PeriodicalId":178300,"journal":{"name":"2010 2nd International Conference on Electronic Computer Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124349480","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}

When learning a network design, one must follow it with practical methods. However, to do the practical and get involve with the real network devices result in a higher cost spending, which make practical method unsuitable. With the new era of computer technology, computer simulation has been considered as a potential method in achieving educational objectives. Thus, this study used the Technology Acceptance Method (TAM) to measure the readiness of students in using network simulation tools. This study applied the survey method where the questionnaire had been used to determined students' intention towards using the simulation tools. The key constructs in this questionnaire include perceived ease of use and perceived usefulness. The respond given indicates that they have agreed towards the use of computer simulation in learning network design. In conclusion, students had shown a high intention in using networking simulation tools provide a means that computer simulation is a potential method in teaching and learning network design today.","PeriodicalId":178300,"journal":{"name":"2010 2nd International Conference on Electronic Computer Technology","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116688632","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}
