With the advancement of computing the arena of software development life cycle and its traditional software architectural models are moving towards more flexible and agile techniques. Service oriented architecture is one of the modern architecture techniques which are composed of loosely coupled and flexible software components called services. Service oriented architecture supports usability, scalability...
In this paper we present some solutions we have devised to improve eye pointing in ordinary PC use. While eye tracking technology has advanced considerably in the last years, several limitations prevent gaze-based interaction from becoming as comfortable and effective as traditional mouse or touchpad input. The proposed approach combines both automatic and manual error correction techniques (namely...
This paper presents a tool and a framework to develop accessible and adaptable digital TV interfaces for disabled and elderly users. The development methodology involves disabled and elderly users early in the design process and optimizes interfaces using a simulation system. The simulator complements existing user centred design processes and helps designers to understand, visualize and measure effect...
Nowadays, the popularity of e-learning systems is growing fast. It is allowed to follow the development web and multimedia technologies. Web-based education became wide spread in the past few years. Various types of learning management systems (LMS) facilitate the development of Web-based courses. The quality of LMS is an important feature that helps ensure a good service. The quality of systems has...
Concurrent programs are difficult to test and debug due to their non-deterministic execution. For deadlocks, traditional deadlock detection algorithms use lock graphs to find cycles, and do not address other types of deadlocks. This paper introduces not only lock-blocked relations but also wait-blocked and join-blocked relations for Java multi-threaded programs, and then proposes two types of deadlocks...
As the percentage of the elderly in the world's population continues to increase, the drive for improved technological support for assisted living follows. A new global objective that aims towards enhancing the elderly quality of life appears where lot of research has been taking place in the field of ambient intelligence consideration factors which includes more comfort, improved health and security...
The United States Senate has become increasingly partisan through the years; in fact it is quite unusual for a Senator to vote against his or her party. The Congressional Close Up system automatically reports on factors that might have influenced a bipartisan vote. The system begins by assigning a topic to the legislation on which a Senate or House vote was focused. The system then uses this assigned...
With the rapid development of information technology, traditional health care is evolving towards a more digital and electronic stage. Electronic Health Record (EHR) deals with basic information and health care related information of residents and it conforms to the relevant standards. It is not only able to provide useful information to medical workers, but also has the ability to exchange resources...
In this paper we investigate the application of Software Aging and Rejuvenation in the context of Critical Infrastructures and Systems-of-Systems. Explained are the characteristics of Systems-of-Systems and classes of Critical Systems, attributes which define their dependability as a high priority requirement. In addition we survey Software Aging and Rejuvenation establishing founding research and...
Efficient use of latest Electronic Health Records (EHR) focus on improved patient care using past patient data. Numerous EHR systems presented by different IT vendors, research groups and organizations for better visualization but still there is a gap of understanding and learning these systems for the physicians and doctors. This research work focuses on a detailed study with different set of doctors...
This paper presents a newly developed mobile robot based multi-agent system with capabilities of robust motion control and intelligent collision avoidance. The system consists of three mobile robots, one master and two slaves. The master robot intelligently takes decisions as to which action to perform to avoid obstacles and collisions. On the other hand, the master mobile robot is capable to swerve...
In this study, approximate symbol error rate (SER) expressions are derived for M-ary phase shift keying (M-PSK) modulation scheme. Here, the channels are assumed to be slow-flat independent and identically distributed (i.i.d) with Rician and Rayleigh fading distributions. Simulation results show that by using maximum ratio combining (MRC) space diversity technique, the communication reliability (i...
This paper aims to investigate Web-searching behaviour for academic resources, the usability issues encountered, and the affect of user education levels on the search process. This experimental study used pre- and post-test questionnaires, Think Aloud Protocol (TAP), and observation methods at the University of East Anglia (UEA). The students engaged in recorded video, audio, and screen session as...
In recent years there has been a rapidly increasing intensity of work going into investigating various methods of facilitating assisted living for the benefit of the elderly and those with difficulties in mobility. The paper describes one such effort which distinguishes itself from the rest by considering and describing a system with true commercial potential and thus significant social impact. Promising...
Along the last decade, organizations have developed BPM (Business Process Management) as a methodology to manage their own Business Processes, with a consequent evolution in the involved systems. Different technical issues such as high availability and growing connectivity, and also economical aspects generated by development and maintenance costs have guided a big number of organizations to choose...
Wearable physical and psychological health monitoring system is proposed. All the sensors which allows monitoring blood pressure, body temperature, pulse rate, measuring sensor for the number of steps, calorie consumption, eeg, GPS receiver, WiFi or Wireless LAN receiver for location estimation, accelerometer are attached to the human body. Measured data are transferred to the mobile devices through...
In this paper we discuss what are the problems facing by the virtual teams and how project tools and techniques help to solve management problems in virtual teams. The rise of the Internet and development of collaborative software enabled globalized organizations to have teams that are geographically distributed. So, there lies diversity of skills, knowledge and culture. This leads to new challenges...
