We also test if the online purchase probability of consumers increases over time. Our data is from the Canadian Internet Use Survey over four years, consisting of at least 23,178 participants per year, relative to previous studies this is a very large dataset. We segment the participants into two groups: 1) those that use only their personal computer (PC) to access the Internet and 2) those that use their PC and a mobile device (mobile phone, tablet, etc.) to access the Internet. For each group we determine the purchase probabilities of consumers for 15 different product category types. Using 95% confidence intervals about the determined purchase probabilities we test if the purchase probability of one group is higher than the other. We find that mobile devices lead to a statistically greater purchase probability in only 4 of the 15 product categories. In addition, the purchase probability of households using mobile devices and PCs to access the Internet only increases between years 2005 and 2007, and is statistically unchanged between all other years. However, for households that use only a PC to access the Internet, the purchase probability increases each year the survey was conducted.","PeriodicalId":300798,"journal":{"name":"2015 Wireless Telecommunications Symposium (WTS)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130249966","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 can lead to many problems including increased risk of cardiovascular disease, diabetes, functional limitations, and disabilities which adversely affect the social and physical abilities of the obese person in daily affairs. While the rising trend of obesity in adults is a serious problem, the rise of obesity in youths is even more severe. Various recent studies have indicated that youth obesity has become so widespread that, if left unaddressed, it would have severe implications on the society health, productivity, and economy. This paper proposes a multiplayer ubiquitous gaming system which unveil the hidden potential within obese youth and improve their skills and physical activities and get them healthy. This is intended to be done through the use of mobile wireless sensors, to provide real time monitoring of the patient bio signals and to suggest suitable actions in terms of physical activity. The system is aimed to engage and encourage youth, particularly in the State of Qatar, in their obesity rehabilitation process, increase their social activities, and help them get healthy in an entertaining way while reinforcing positive exercise habits.","PeriodicalId":300798,"journal":{"name":"2015 Wireless Telecommunications Symposium (WTS)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132270958","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}

For the proposed scheme, the estimation of the I/Q and channel parameters have been performed in the frequency domain. By the help of the estimated values, a nominal I/Q gain and phase has been obtained which has been fed back to do the I/Q correction in the time domain. The corrected signal with some residue I/Q imbalance along with the channel have been compensated afterwards. The performance of the proposed scheme has been extensively studied by means of computer simulations using MATLAB. With the proposed ACCC scheme, the signal to noise ratio (SNR) degradation is approximately 2 dB higher than the reference symbol error rate (SER) obtained for no I/Q imbalance and channel condition, at a specified symbol error rate (SER) of 10-3. Next, in order to assess the robustness of the proposed scheme, it has been compared with three other previously published schemes, under different conditions. The results depict that the proposed ACCC scheme significantly outperforms the three other existing schemes by expending less than 2% of the subcarriers as pilots.","PeriodicalId":300798,"journal":{"name":"2015 Wireless Telecommunications Symposium (WTS)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129952041","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}
