Medical Experts Systems have been one of the earliest and ongoing pursuits of the Artificial Intelligence (AI) community. Unfortunately, they still remain a largely unrealized goal. The systems that have been developed are either prototypes, or involve only small knowledge domains. One of the main reasons for this situation is explained as the lack of domain specific models. While it is true that...
his paper presents a novel ensemble model of artificial neural networks for rainfall forecast incorporating dynamic variable selection. In the first phase of the model, meteorological variables optimal to the response (here rainfall) are selected with the optimal lag value of the response variable. A dynamic variable selection method named, time series least angle regression (TS-LARS) is applied in...
In this paper we present a novel framework for abnormal behavior detection in crowded scenes. For this purpose, the theory of topological simplification on the dense field is extended to the sparse particle motion field, which is used to describe the dynamics of the crowd. We propose two new methods for analysis of boundary point structure and extraction of critical point from the particle motion...
Robocup is a popular test bed for AI programs around the world. Robosoccer is one of the two major parts of Robocup, in which AIBO entertainment robots take part in the middle sized soccer event. The three key challenges that robots need to face in this event are manoeuvrability, image recognition and decision making skills. This paper focuses on the decision making problem in Robosoccer -- The goal...
Application of Wireless Sensor Networks (WSN) in many fields has achieved a significant advances, many research can be seen in military, industrial control surveillance, and bush fire and wild habitant monitoring, However, it is a bit too early to claim the application of WSN in the domain of Medicine and Healthcare (M&HC) a big success. The major obstacle is the concern raised by the users that...
This article develops a charging scheme that is simple and easily usable for the users and provides them with the incentives to use only the resources they need. This scheme is developed on the time-volume charging approach to show how the contributing providers can share the total charge earned by each mobile and wireless service instance in a fair way, with each provider collecting the portion of...
This research focuses on the development and performance evaluation of MMS framework for internet applications. The details of the architecture and algorithms employed in the MMS framework for message delivery are presented. We implement the proposed MMS framework for internet application by building a mobile telemedicine system. On the client side, we develop MMS application that implements data...
Recently, Hsiang and Shih proposed remote user authentication scheme using smart cards, they claims that their schemes defended against parallel session attack, and password guessing attacks, In this paper, we show that Hsiang and Shih's schemes are still vulnerable to off-line password guessing attacks and undetectable on-line password guessing attacks. Notably, problems remain in situations where...
