Dynamic Healthcare Interface for Patients
AbstractCanadian healthcare is a fundamental part of society. Challenges such as the aging baby boomer generation require the healthcare industry to meet higher demands while using fewer resources. Computer systems designed to record and report physical health properties of an individual personcan be used in part to accomplish this task. In this paper, we present the architecture of a hypothetical multi-agent system designed to provide healthcare information about specific patients through continuous monitoring. The resulting data from the system is accessible by the patient to whom it belongs as well as his or her healthcare professional. Furthermore, the proposed system utilizes an adaptive user interface for the purpose of improving the overall experience for users with poor vision or motor skills. Specifically, we focus on the implementation of several of the key components involved in the adaptive user interface: learning component and the user model. To demonstrate the feasibility of the implementation two scenarios are provided. We conclude with several possible future directions for this research
An Adaptive User Interface in Healthcare
AbstractHealthcare is a broad subject with many different challenges, yet it is important and relatable to everyone. The aging Baby Boomer generation is an important healthcare issue today. In Canada, and many other developed nations, the number of citizens reaching the age of retirement and seniority is growing faster than the rate of citizens working and providing health related services. As people age they tend to require more frequent checkups and health services, ultimately putting a bigger resource drain on healthcare infrastructure. New advancements in Computer Science and Engineering are allowing the development of next generation applications with the purpose of providing healthcare services in a cost effective and efficient way. This paper proposes a multi-agent system for tracking and monitoring health data for patients. Furthermore, agents within the system use reinforcement learning techniques to build an adaptive user interface for each human user. The actions and behaviour of users are monitored and used to modify their respective user interface over time. To demonstrate the feasibility of the architecture, two scenarios are provided. We conclude with several possible future directions for this research
Comparative Study of Fingerprint and Centroid Localization Protocol Using COOJA
AbstractSensor networks are in a numerous number of applications. However, implementing wireless sensor networks present new challenges compared with theoretical networks. Cooja is the Contiki network simulator. It allows large and small networks of Contiki motes to be simulated; moreover, motes can be emulated at the hardware level. In this paper, we evaluate the accuracy performance of two very well-known localization protocols, namely: fingerprint and centroid protocols using Tmote sky in Cooja. It is worth mentioning that this the first time this study is conducted in Cooja. The results conform to the theory that fingerprint protocol has a better performance than centroid in terms of accuracy when accuracy is quantified
Real-Time Performance Evaluation for Flooding and Recursive Time Synchronization Protocols over Arduino and XBee
A Web-Based Application of TELOSB Sensor Network
Sensor network can be used in a numerous number of applications. However, implementing wireless sensor networks present new challenges compared with theoretical networks. In addition, implementing a sensor network might provide results different from that derived theoretically. Some routing protocols when implemented might fail to perform. In this paper, we implement three routing protocols, namely: Dynamic MANET on-demand, Collection Tree and Dissemination protocols. To compare the performance of these protocols, they are implemented using a Telosb sensor network. Several performance metrics are carried out to demonstrate the pros and cons of these protocols. A telemedicine application is tested in top of the implemented Telosb sensor network at King Fahd University of Petroleum and Minerals Clinic in Saudi Arabia, utilizing Alive ECG sensors
Fault Reconnaissance Agent for Sensor Networks
One of the key prerequisite for a scalable, effective and efficient sensor network is the utilization of low-cost, low-overhead and high-resilient fault-inference techniques. To this end, we propose an intelligent agent system with a problem solving capability to address the issue of fault inference in sensor network environments. The intelligent agent system is designed and implemented at base-station side. The core of the agent system – problem solver – implements a fault-detection inference engine which harnesses Expectation Maximization (EM) algorithm to estimate fault probabilities of sensor nodes. To validate the correctness and effectiveness of the intelligent agent system, a set of experiments in a wireless sensor testbed are conducted. The experimental results show that our intelligent agent system is able to precisely estimate the fault probability of sensor nodes
السلوك اللزج لمحلول الكربو كسي ميثيل سليلوز الملحي المخفف قبل و بعد تعرضه للانحلال الضوئي
Photodegradation curve of carboxymethylcellulose (CMC) in aqueous solution has been reported. Densities and solution viscosities of very dilute CMC salt solution before and after UV-irradiation have been measured. UV-irradiation of CMC decreases the values of density, specific, reduced and intrinsic viscosities, molar mass, hydrodynamic volume, expansion factor, real and ideal chain dimensions of CMC in solution. In contrary, it increases the solute-solvent interaction and decreases the solute-solute contact in the solution of degradable CMC.تم دراسة منحنى الانحلال الضوئي للكربوكسي ميثيل سليلوز (CMC) بمحلوله المائي . أجريت قياسات الكثافة و اللزوجة ل CMC (المتواجد في محلول ملحي) بمنطقة التركيز المخفف جدا قبل و بعد تعرضه للأشعة فوق البنفسجية. لوحظ أن هذه الأشعة تقلل من قيم الكثافة، اللزوجة المختزلة واللزوجة الجوهرية، و كذلك الكتلة المولارية والحجم الهيدروديناميكي و معامل التمدد وأيضا الأبعاد الحقيقة و المثالية لسلسة ال CMC في المحلول. بينما زاد تفاعل المذاب مع المذيب وقل اتصال جزيئات المذاب مع بعضها الآخر في المحلول المنحل للكربوكسي ميثيل سليلوز بسبب تأثير أشعة UV
