A study on possible application of RFID system in different real-time environments

Abstract: This paper lists all applications of RFID technology in various sectors. It discusses the advantages and disadvantages of deploying the technology in the respective fields by elaborating the methods and technical tools used. There are several parameters that determine the use of RFID such as the read range, reader frequency, and type of tag. The performance is identified by reliability, cost effectiveness, efficiency and usage. A detailed insight is given about RFID in the traffic control system for possible application in smart city development. Many countries control the traffic lights using tags and readers to enable police officers to make better decisions. It also helps in finding vehicles that commit crime, stolen vehicles, over-speeding vehicles, vehicle congestion, prevent accidents and many others. As this technology is not very popular in many countries, we provide an analysis to understand the benefits of RFID. The real application of the technology is judged against all parameters to offer a solution for practical use.

Semantic based Personalized Framework for Information Retrieval

Abstract: Traditional information retrieval systems are mostly keywordbased and retrieve documents or information by matching keywords. These systems lack a meaningful description for information, so it is difficult for users to find more relevant information. To provide what a user really needs, a framework of information retrieval based on semantics has been proposed in this paper. In this framework the semantics in the user query are identified and these are summarized according to the context. Then the results are classified into possible domains or groups and displayed to user according to his choice from domain the results are re-ranked. By this framework we provide users a convenient and more precise search service with personalization. General Terms Information Retrieval, Clustering, Ranking

The Impact of Social Media on Society

Abstract: Over the past decades, Information and communication technology has undergone tremendous changes, and one of the benefits it has brought is the emergence of social media. As each day passes by, new inventions are developed. The development of mobile technology has made a significant impact in shaping the role of social media. Research shows that mobile devices have taken dominate the world due to the total time spent online. Mobile devices have made it easier for anyone with a device that has internet connectivity to access social media across the globe. Nonetheless, although social media has brought positive impacts on society, the negative effects cannot be overlooked. This paper analyzes the impacts of social media on individuals and the society in general. By exploring different sources of literature, this article expounds on the effects of social media such as crime and security, lack of privacy, political influence, and cyber bullying.

Using Location-Based Social Media Data to Observe Check-In Behavior and Gender Difference: Bringing Weibo Data into Play

Abstract: Population density and distribution of services represents the growth and demographic shift of the cities. For urban planners, population density and check-in behavior in space and time are vital factors for planning and development of sustainable cities. Location-based social network (LBSN) data seems to be a complement to many traditional methods (i.e., survey, census) and is used to study check-in behavior, human mobility, activity analysis, and social issues within a city. This check-in phenomenon of sharing location, activities, and time by users has encouraged this research on gender difference and frequency of using LBSN. Therefore, in this study, we investigate the check-in behavior of Chinese microblog Sina Weibo (referred as " Weibo ") in 10 districts of Shanghai, China, for which we observe the gender difference and their frequency of use over a period. The mentioned districts were spatially analyzed for check-in spots by kernel density estimation (KDE) using ArcGIS. Furthermore, our results reveal that female users have a high rate of social media use, and significant difference is observed in check-in behavior during weekdays and weekends in the studied districts of Shanghai. Increase in check-ins is observed during the night as compared to the morning. From the results, it can be assumed that LBSN data can be helpful to observe gender difference.

In the Era of Social Media: Is it time to establish a code of online ethical conduct for healthcare professionals?

Abstract: Social media is becoming an invasive part of the lives of many professionals including those in the healthcare field. One of the countless implications of such an invasion is how the healthcare professional's engagement with social media affects the traditional doctor-patient relationship. The online presence of professionals should be carefully self-monitored as it affects the individual's reputation and society's perception of their profession. Therefore, the contents of public and personal accounts must differ according to their purpose. In the public eye, conflicts of interest must be declared and scientifically-based medical advice should be clearly differentiated from experience-based advice, personal opinions or commercial advertisements. Online doctor-patient relationships risk the privacy of patients as well as the personal privacy of the healthcare professional. Personal accounts created for friends and family should be kept separate from public accounts created for educational, professional or commercial purposes. Published educational material should be clearly differentiated from commercial material so that it is easier for the public to make an informed decision. This paper proposes a code of online ethical conduct to be implemented in Oman.
