However, the insufficient bandwidth of video conferencing may often result in high frequent video disruptions, mosaic pictures, frozen pictures and temporary lack of sound. This research, therefore, attempts to analyze the audio and video bandwidth requirements. We aim to identify the minimum bandwidth that would still allow the video conference system to operate while yielding reasonable audio and video quality. We collect the bandwidth data from the video conferencing system from September 2013 to December 2013, both in per minute and per day values and analyze them using Linear programming and Regression analysis.","PeriodicalId":224049,"journal":{"name":"The 4th Joint International Conference on Information and Communication Technology, Electronic and Electrical Engineering (JICTEE)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115642880","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}

Its significant requirement is a high accuracy in dense multipath fading environments. This paper improves the main problem of indoor localization by using fingerprinting technique based on ultra wideband (UWB) channel measurement. In addition, the neural network algorithm is used to find the location that has 3 dimensions, x plane, y plane and z plane. The first path loss, the delay times of the first part, the average path loss and the average of delay time were applied to create the ultra wideband radio propagation parameters for fingerprinting technique. the results are shown in terms of histogram of distance errors between update and non-update the databases and countour graph of each of distance errors on the coordinates. According to the results, the fingerprinting technique with update database can identify the location more correctly than the fingerprinting technique with non-update database. It had accuracy at 1 meter as 88.57%. while the fingerprinting technique with non-update database was affected from the environment and the accuracy at 1 meter was lower than the fingerprinting technique with update database all the times of experiment.","PeriodicalId":224049,"journal":{"name":"The 4th Joint International Conference on Information and Communication Technology, Electronic and Electrical Engineering (JICTEE)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122524270","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}

There are many factors for causing the changing backbone of the people. However, at present there are still studies quite a few changes in the lumbar spine. Therefore, all data are obtained from Lerdsin hospital. The purpose of this study is to investigate the relationship between age, gender and body mass index of the patients are admitted because of back pain using method for measuring the angulation of the bone with Cobb's Angle method. X-Ray images of the patient's Lerdsin hospital are 493 of people aged between 20-88 years which they can be divided into four groups: 1) 20-29 years, 2) 30-39 years, 3) 40-49 years and 4) over 50 years. The calculations of mean and standard deviation are compared with the relationship between age, gender and body mass index (BMI) affecting the curvature of the lumbar spine. The results show that the first, second, third and fourth groups are approximately at 26.39 ± 12.02 degrees (64 people), 25.78 ± 12.16 degrees (85 people), 26.99 ± 12.79 degrees (106 people) and 25.53 ± 12.96 degrees (243 people), respectively. For the third group, the curvature of the bone is highest all of the age groups, and females are higher than males. It is found that the angle of curvature of the lumbar spine by age are analyzed by One-way ANOVA (p>0.05). The results of the age do not affect the curvature of the lumbar spine and they show patients with underweight and overweight patients. It makes effects of the curvature of the spine that females are more than males. Experts estimate a basis for evaluating underlying disorder patients to receive treatment for back pain that is in the level of risk.","PeriodicalId":224049,"journal":{"name":"The 4th Joint International Conference on Information and Communication Technology, Electronic and Electrical Engineering (JICTEE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129010876","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}
