This paper discusses the Design and Implementation of Hierarchical Thread Pool Executor (HTPE) using the non blocking queues. This work enhances the performances of the Distributed Shared Memory (DSM) Programming. Few Java based DSMs make use of the concurrent utilities of Java that support the thread pool executor with blocking queues (i.e. Jackal). The study of the new proposed algorithm is done in a simulated environment which demonstrates that if the non-blocking queues are used, their performance improve significantly. The Hierarchical Thread Pool Executor using the non blocking queue has been simulated on the cluster environment using MinHeap tree data structure.

Magnetic Induction Tomography (MIT) is a contactless method interested in conductivity properties of the object. In MIT system, excitation coil plays an important role since it generate primary field which then will propagate through the object (in this case is biological tissues) going to be imaged. The main problem in MIT is the magnitude of primary field is very large compare to secondary field generate by the tissue due to tissues low conductivity. This primary field besides disturb the detected secondary signal at the receiver, it also introduce interference to the neighbour’s circuit. The main objective of this research is to design an excitation coil which has the capability of focusing the primary field only to the object while at the same time reducing the interference to the neighbour’s circuit. The simulation results have shown that through the design, the primary field can be focused and the interference can be reduced.

Portals are the central point of communication, customer services and commerce through networks. Most service provider portals don’t have these facilities as the investors are focusing on experience rather than modern technologies. Portals are continuous projects and need updates time to time with new technologies and human expertise. The objective of this paper is to propose a complete service delivery technique and all the compulsory steps in portal implementation. The presented model is benefited in service delivery to all customers and for the improvement of portal implementation functionality.

This paper describes a 2D simulator of obstacle avoidance using LRF for mobile robots. In this work, the 2D map of environment is built based on two colors, red and black, where the red represents the obstacles and the black represent the free spaces. The obstacle avoidance is performed when the RLF detects the red areas with the measured distance is less than 1m. The simulator can be used as offline and online tool for mobile robots. In 2009, it was used to offline test obstacle avoidance algorithms in some areas of 1km course of robot challenge named "Tsukuba Challenge" and online predict the robot trajectory in the next few meters during the autonomous navigation. As the results, our mobile robot completed the 1km course with the total time of 51m07s.

In India as per the survey conducted by Indian Medical Society (IMS) in the year 2009, it has been revealed that 75% of qualified consulting doctors practice in urban centers and 23% in semi urban areas and only 2% at rural areas whereas majority of the patients come from rural areas. The non availability of proper medical facilities at right time is a huge problem for people at rural places. Providing a cost effective solution for this problem by utilizing the available resources to give good medical facilities to not only to urban but also to rural areas definitely reduces the gap present. The challenges that have to be faced to achieve this change are improve patient safety, improve the quality and efficiency of patient care, and reduce healthcare delivery costs at rural areas. The method that can be applied successfully to overcome all these challenges is Telemedicine. This paper introduces the innovative concept of developing an efficient Electronic Health Record (EHR) used to implement Telemedicine by utilizing the advances made in both Information technology and Communication systems. This application acts as a bridge between skilled doctors and the rural people.

A radical change in technical approach is needed to achieve electronic records suitable to support an engineered system of healthcare at rural and isolated areas. The challenges that have to be faced to achieve this change are improve patient safety, improve the quality and efficiency of patient care, and reduce healthcare delivery costs at rural areas. Electronic Health record (EHR) is a much anticipated solution for this problem which gives a true lifetime, person centered medical record of a patient. This paper introduces the innovative concept of developing an efficient EHR in a way that effectively implements the creation, updation, maintenance, representation and transmission of the medical data. In this implementation, the static information such as identification details, lifestyle habits, etc will remain in the database and only the dynamic data such as the rapidly changing health status of the patient along with the graphical and real-time data such as cardiograph signals, pathological reports are modified from episode to episode and can be sent using proper transmission media to the nearest Expert Centre for immediate diagnosis. The vital data which needs to be transmitted is compressed using the suitable and efficient compression technique for reducing the time of transmission.

This paper exhibits a new structure based on a meta-policy approach using an intelligent anomaly based host based intrusion detection system, These access control decisions are decided in agreement with a meta-policy. The combination of policy and host based intrusion detection system approach depends on operating systems integrating with mandatory access control. The proposed structure controls a extended set of attacks and provides the management of the system policy, compared to other existing access control approaches and policy based host based intrusion detection system techniques. Items are given about methods used for the meta-policy, and implementation of the structure. We used genetic algorithm to try to select what was the best set of features and chose a Bayesian network, that is trained by using the selected system log on operating system.

Active safety is an important feature of a modern vehicle to provide precaution warning or compensatory control before the pre-crash stage of vehicle safety. All vehicle signals and information are acquired by several in-vehicle sensors on ECUs or surrounding vehicles, and integrated in vehicle gateway through in-vehicle or vehicle-to-vehicle communications. The information exchanged among the host and surrounding vehicles provides comprehensive vehicle and driving status of each vehicle, so the driver can drive more safely with the cooperative driving mechanism. The demonstration system consists of a vehicle gateway, which is based on a heterogeneous multi-core processor, consisting of one ARM core for I/O control and system management and two DSP cores for intensive computation of information fusion. After reaching within the communication limit, the vehicles set up time synchronization and then exchange vehicle information. The acquired sensor data and received vehicle information are time aligned and fed into PAC DSPs for information fusion, which consists of four phases, signal processing, location mapping, trajectory prediction and risk assessment. The risk assessment evaluates the probability of car crash and broadcast the warning message to its surrounding vehicles, if the risk level is raised beyond a threshold. The cooperative driving is fulfilled by sharing the vehicle information and emergency warning through wireless communication, so a driver can be aware of the dangerous situation and also be suggested an adequate response earlier.

A software development life cycle model based on predicting and deciding maximum possible changes which can come in the time line of project completion has been proposed. The model makes it easy for developers to manage the constantly changing requirements and specifications. This model instead of focusing on people and resources focuses on architecture. It is not a replacement for Agile and other iterative models. It is addition of a new perspective of architecture to the existing software development life cycle methodologies.
