The Contagion Effect of the 2007 Global Financial Crisis on the Malaysian Stock Market

This paper is an investigation on the impact of the 2007/2008 global financial crisis and foreign exchange rate on the stock market of Malaysia in two sub periods namely, pre-crisis (January 2002 till June 2007) and during crisis (July,2007 till December 2010). The findings showed that the stock market returns in US and Malaysia were depressed during the period of crisis. The correlation coefficient was strongly significant during the period of the crisis. In addition, multiple regression analysis provided evidence that contagion effects exist to the Malaysian stock market did exist during the US financial crisis, however the foreign exchange rate was not significant during the said financial crisi

Design, Fabrication, and Validation of a Highly Miniaturized Wirelessly Powered Neural Implant

We have recently witnessed an explosion in the number of neurons that can be recorded and/or stimulated simultaneously during neurophysiological experiments. Experiments have progressed from recording or stimulation with a single electrode to Micro-Electrode Array (MEA) such as the Utah Array. These MEAs can be instrumented with current drivers, neural amplifiers, digitizers and wireless communication links. The broad interest in these MEAs suggests that there is a need for large scale neural recording and stimulation. The ultimate goal is to coordinate the recordings and stimulation of potentially thousands of neurons from many brain areas. Unfortunately, current state-of-the-art MEAs are limited by their scalability and long-term stability because of their physical size and rigid configuration. Furthermore, some applications prioritize a distributed neural interface over one that offers high resolution. Examples of biomedical applications that necessitate an interface with neurons from many sites in the brain include: i) understanding and treating neurological disorders that affect distributed locations throughout the CNS; ii) revolutionizing our understanding of the brain by studying the correlations between neural networks from different regions of the brain and the mechanisms of cognitive functions; and iii) covering larger area in the sensorimotor cortex of amputees to more accurately control robotic prosthetic limbs or better evoke a sense of touch. One solution to make large scale, fully specifiable, electrical stimulation and recording possible, is to disconnect the electrodes from the base, so that they can be arbitrarily placed, using a syringe, freely in the nervous system. To overcome the challenges of system miniaturization, we propose the “microbead”, an ultra-small neural stimulating implant, that is currently implemented in a 130nm CMOS technology with the following characteristics: 200 μm × 200 μm × 80 μm size; optimized wireless powering, all micro-electronics on single chip; and integrated electrodes and coil. The stimulating microbead is validated in a sciatic nerve by generating leg movements. A recording microbead is also investigated with following characteristics: wireless powering using steerable phased coil array, miniaturized front-end, and backscattering telemetry. These microbeads could eventually replace the rigid arrays that are currently the state-of-the-art in electrophysiology set-ups

Communication system for controlling smart appliances using power line communication

icrocontroller-based master and slave units are designed with serial ports for communication with a computer and a transmission port to couple the signal to modems at both ends. The programming of the microcontrollers at either endfor formatting the data bits before they are sent down the power line and the development of software for putting in place the required master and slave protocols is presented. Coupling data signals to power line through interfacing circuits is a challenging task as power line and the communication system operate at two extremes -very lowfrequency and high powerfor the power line while communication is working at very highfrequency and very low voltage and current levels. Hence, the coupling circuit to be designed must be capable to withstand the high power system side in order to prevent a damage being done to the electronic side of the communication system. At the same time it must be reliable enough to make sure that data bits are transferred on to the power line with high accuracy. The interfacing circuits are designed and tuned to frequency contents making the bits of data. The frequency performance of these coupling circuits is presented, showing the range a power line can be used for communication ofsuch data

Stochastic Time series analysis of Runoff data of the Blue Nile at Eldeim, Sudan

To improve the management of operation system for the Roseires reservoir it is necessary to know the hydrological system of the Blue Nile river, which is the main water source of the reservoir. In this work, a Modified Thomas Fiering model for generating and forecasting monthly flow is used. The methodological procedure is applied on the data obtained at the gauging station of Eldeim in Blue Nile, Sudan. The study uses the monthly flows data for years 1965 to 2009. After estimation the model parameters, the synthetic time series of monthly flows are simulated. The results revealed that the model maintained most of the basic statistical descriptive parameters of historical data. Also, the Modified Thomas Fiering model is applied to predict the values of the next fifty-five years, with excellent results that conserved most basic statistical characteristics of runoff historical series. The Modified Thomas Fiering model is able to realistically reconstruct and predict the annual data and shows promising statistical indices

التقانات اللغوية التركيبية الحديثة: آليات تحويل النص العربي إلى كلام منطوق Modern synthetic linguistic technologies: Arabic text to speech mechanism

في ظل تطور تقانات الحاسوب وتنامي أدوات الاتصال والتواصل، باتت الحاجة إلى استخدام الحاسوب في الكثير من التطبيقات الحيوية أكثر أهمية من ذي قبل؛ حيث استحالت إلى تطبيقات مفيدة وجيدة في كثير من مجالات الحياة العامة والخاصة على سواء. إذ نلفي، في حالات، أن استيعاب النص المسموع يفوق استيعاب النص المقروء عبر الوسائل والتقانات المهمة لمساعدة من يعاني من إجهادات وصعوبات في القراءة. ولمـا كـان التواصل الكلامي أسهل وأنجع أنواع التواصل، فإنه يجرى العمل حاليًا على إنشاء جيل مـن الحواسيب في مكنتها التواصل كلاميًا مع المستخدم؛ حيث تأتي أنظمة توليد الكلام في مقدمة هذه المجالات الحيوية. إن الهدف من عملنا هذا، هو الوقوف على اللسانيات الحاسوبية العربية بحثًا وتطبيقًا على أمل المساعدة على كيفية استخدام اللغة العربية لدخول مجتمع المعرفة. ومما لا شك فيه أن التعددية اللغوية باتت واقعًا مفروضًا ومكشوفًا في كل المجتمعات الدولية، لكن ليس على حساب اللغة العربية في المناطق العربية؛ مما يفترض إيلاءها الأهمية الكبرى رغبة من محبيها ومتقنيها بهدف تطويرها ومواكبتها عصر التقانات الحديثة. The development and growth of information and communications technologies led to the use of digital era in many vital applications in our daily life that require human-machine interaction. As verbal communication is the easiest and most effective communication, a generation of technologies are being created to enable communication with the user. Speech-generation systems come at the forefront of these vital areas. However, most of the available Arabic Text To Speech Systems have drawbacks such as discontinuity, limited vocabulary and poor naturalness. The purpose of this work is to identify the Arabic linguistics technologies in research and application in the hope of helping how to use the Arabic language to enter the knowledge society. There is no doubt that multilingualism has become an imposed reality in all international societies, but not at the expense of the Arabic language in the Arab regions. This is supposed to give great importance to the desire of its fans and technocrats to develop and cope with the age of modern technologies

Neuropsychiatric disorders among Syrian and Iraqi refugees in Jordan: A retrospective cohort study 2012-2013

Background: The burden of neuropsychiatric disorders in refugees is likely high, but little has been reported on the neuropsychiatric disorders that affect Syrian and Iraqi refugees in a country of first asylum. This analysis aimed to study the cost and burden of neuropsychiatric disorders among refugees from Syria and Iraq requiring exceptional, United Nations-funded care in a country of first asylum. Methods: The United Nations High Commissioner for Refugees works with multi-disciplinary, in-country exceptional care committees to review refugees’ applications for emergency or exceptional medical care. Neuropsychiatric diagnoses among refugee applicants were identified through a retrospective review of applications to the Jordanian Exceptional Care Committee (2012-2013). Diagnoses were made using International Classification of Disease-10th edition codes rendered by treating physicians.Other Research Uni
