Relations between negative health effects like asthma and lung cancer and elevated levels of the environmental factors, such as air pollution, tobacco smoke and humidity, have been detected in several large scale exposure studies. Thus, public health care and service systems require the ability to track, monitor, store, and analyze individual moving trajectories along with several environmental conditions the individual is exposed to in order to identify meaningful relationships among theses data and derive conclusions for environmental health decision support. With continued advances in information technology, patients can be monitored with numerous intelligent devices. Sensors can be integrated into their mobile devices such as smart phones for continuous health assistance and disease attack prevention. However, researchers must overcome many challenges, such as data acquisition, data scales and data uncertainty, in order to develop a real-time health monitoring system. In this paper, we propose a system framework for modeling and analyzing individual exposure to environmental triggers of asthma attacks. The proposed system can provide a tool to develop more accurate asthma prevention and care plans enabled by real-time patient monitoring and communication through alerts for potential environmental triggers.

Biologists have shown that algae are the first to be implicated in climate changes and vice versa. The goal of this research effort is to predict the future climate using algae species living in a lake in the past. On performing age depth profile analysis on the sediment core obtained from the bottom of Jewel Lake in Alaska, a dataset of 163 records is derived. The 163 records collectively represent 4,308 years interval. Each record is composed of 86 attributes: Year, 84 species of algae, and Climate. The relevancy analysis of the attributes of the dataset identified only four species relevant to climate. An extrapolation system's Architecture with two stages of prediction process fit to meet the goal of this research effort. Three different predictive models of regression analysis, neural network, and ID3 were investigated for possible use in development of the extrapolation system resulting in four possible ways among which the best one uses neural networks in both stages. The best extrapolation system was able to predict climate for a year in future, within the next 278 years, with the average accuracy of 80%.

We are developing a compiler system, Melasy+, which is at a level higher than compiler systems of various model-checking and hardware description languages. Melasy+ describes a single code and allows model-checking and operation tests on an actual machine via a code generator for each language. In this study, for an XML intermediate representation code that was output by Melasy+, the elements of the target circuit are analyzed to generate a detailed list and then static analysis of the circuit is carried out. The net list after regeneration is a digraph and the meta-information obtained in the analysis is given to its edge.

Social news websites (e.g. Digg, Reddit) have become a new and influential global phenomenon. Such websites present opportunities for individuals to participate in news creation and diffusion and thus have fundamentally transformed the ways people consume and share news. Yet, despite the popularity of these websites, factors influencing news sharing are not well documented. Hence, the objective of this study is to understand the determinants of news sharing in social news websites by examining the influence of news attributes as well as news sharers. A sample of 552 news stories was collected from a well-known and established social news website. Regression analysis was employed to analyze the data. Results indicated that in terms of news attributes, both the salience of news content and types of news were significant predictors of news sharing in social news websites. Specifically, news stories attracting more comments from users were more likely to be shared. We also found that soft news (e.g. sports and entertainment) were more frequently shared than hard news (e.g. politics and business). Contrary to expectations, the influence of news sharers did not significantly impact the extent of news sharing. The implications of the findings and directions for future research are discussed.

This research utilizes several well known forecasting techniques in combination with Empirical Mode Decomposition (EMD) to investigate the trade-offs of EMD's decomposition (sifting) step for forecasting the arrival workload of an enterprise cluster. The research is based on earlier work on the forecasting potential of EMD. Results show that EMD helps to improve forecasting results. Parallelization is used to perform extensive investigation across the full range of data. Future research is to increase the statistical confidence in the level of improvements possible when EMD is used as a decomposition method for forecasting.

In the recent decades, Information Technology has had a great influence on many aspects of human's life. Electronic mails, electronic commerce, and the World Wide Web are examples of revolutionary ideas which changed human's life. There have also been many efforts in the field of adopting IT tools in architectural design and building construction. Many of these efforts are sparse and lack a well-designed cohesive scenario. In this paper, we present a revolutionary system architecture to facilitate all levels of architectural design by connecting parts involved in the process of designing and construction, exploiting capabilities of today's and future's IT tools. This system can further be adopted and enriched in a top-down sense by engineers and software developers working in various fields of computer science and engineering.

Vehicles may move at high speed in vehicular ad-hoc networks (VANETs) and the network topology changes arbitrarily as the nodes move. Vehicles may not find suitable resources because sharing information could quickly become obsolete or irrelevant resources. This paper proposes an efficient geo-aware Peer-to-Peer (P2P) search mechanism to enable resource discovery and sharing in VANETs. We propose discovery and sharing schemes based on the virtual backbone architecture, and then limit the data exchanging region to reduce unnecessary message transmissions. Because the resource node changes very fast, the coordinator must be set to maintain the local node of geographic information in the network. In this scheme, coordinators are established to store information and manage local resource information. In order to ensure dissemination performance, it must guarantee that vehicles possess enough resource pieces to allow efficient bartering. Furthermore, three kinds of piece selection mechanisms, including Nearest-First, Rarest-First, and In-Order are proposed to download resource pieces from other vehicles and to improve the dissemination efficiency. Experiment results demonstrate that our searching and sharing schemes are efficient and outperforms other schemes in terms of satisfactory ratio and download time.

Teaching "socially intelligent computing" concepts in introductory computer science courses is possible through curricular projects that involve students developing their own collaborative chatbots. Chat bots are programs that interact with users in a conversational context. Introductory CS students can write these types of programs using a framework of Peer-to-Peer (P2P) libraries presented in this poster paper. When the students build chat bots that collaborate with one another, the students are introduced to a branch of machine intelligence called socially intelligent computing.

It is always important to test software products to ensure that they are correct and are built according to the specified requirements. Testing may not only occur after developing the software product. In the other stages of the software development process (e.g. requirement and design stages) testing may occur to detect errors early which can be more effective in saving project scarce resources. In this paper, an expert system is built for dental clinical treatment. A graph is automatically generated based on a formal model built for possible diseases and symptoms related to dental clinics. Later on, a software application is built to automatically generate, execute and verify test cases from the dental expert system formal model. Coverage is also evaluated based on the graph: nodes, edges and paths. Initial test results showed problems with the developed formal model in producing several dead lock paths. Several cycles of improvements to the model were implemented based on the test output and coverage results. Results showed that such approach can be very useful in evaluating expert systems in general.
