ED has been proposed for spectrum sensing in cognitive radios and various wireless applications. A closed form solution for modeling ED under shadow-fading conditions using lognormal distribution is complicated and is the main drawback. In KG fading model, shadowing is modeled by Gamma probability density function (PDF) and Nakagami-m distribution is used to represent the small-scale random variations of the received signal envelope. By applying the alternative series representation of Marcum-Q function, We obtain a closed form expression for ED based average detection probability over KG fading. The derived expressions are validated, and analytical results are verified by numerical computations and simulations for scenarios of practical interest Further, these results are considered for performance analysis and improvement of sensing by varying parameters of KG fading channel under light and moderate shadowing.","PeriodicalId":207616,"journal":{"name":"2011 IEEE 14th International Multitopic Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125438726","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}

In this paper, we present a robust mechanism to identify the focus of attention of the medical personnel (doctors, nurses etc.) while dealing with patients, equipment and other data. We propose to use wearable gaze-directed cameras that can capture the exact point where the person is looking to identify his focus. We exploit the fact that is human nature to “look” at the relevant object and/or person attended to. We demonstrate two sample scenarios: First, in a ward with multiple patients, we identify the patient approached by the doctor so that only his information is loaded. Second, in a setup of multiple patients where each has to be given medicines by a nurse one by one while only the medicines relevant to current patient is highlighted in turn. We argue that our approach is unobtrusive and robust, and is capable of handling scenarios involving multiple equi-probable elements of interest.","PeriodicalId":207616,"journal":{"name":"2011 IEEE 14th International Multitopic Conference","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121557355","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 local temporary tabu memory has been used to learn the pattern and it can combine known information from past viruses with a type of prediction for future viruses. This is achieved through certain generated test signature of viruses associated with e-mail over landscape. A non-uniform and non-decreasing time function for pheromone deposition and evaporation ensures that subsequent ants who are close enough to a previously selected trial solution will follow the trajectory or test landscape. They are capable to examine gradually thicker deposition of pheromone over the trajectory. It is empirically shown that the proposed modified pheromone learning mechanism can be an alternative approach to detect virus pattern for e-mail messages.","PeriodicalId":207616,"journal":{"name":"2011 IEEE 14th International Multitopic Conference","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127239197","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 designed filter circuit is capable of realizing high-pass, band-pass and low-pass responses with the choice of component matching. The realized transfer function is independent of any active parameter and therefore does not exhibit active sensitivity. Highly stable responses are obtained.
