BACKGROUND Topiramate is an antiepileptic drug that has been approved for migraine prophylaxis. Despite appropriate efficacy for migraine prophylaxis, some patients cannot tolerate its adverse effects. The aim of this study was to compare the efficacy of zonisamide, another antiepileptic drug, with topiramate in decreasing the frequency and severity of(More)
BACKGROUND Recent researches have known long term infections such as periodontal disease to be related with the process of atherosclerosis. Periodontitis causes peripheral inflammation and immune cell stimulation which leads to an increase in C - reactive protein (CRP) and IgA Ab and there is a definite relation between cardiovascular disease, CRP increase(More)
In this study, a new space time block code (STBC) is proposed for long term evolution-advanced (LTE-A) system that is equipped with three time slots and two antennas. The introduced STBC has the following characteristics: i) it achieves rate one and full diversity, ii) its maximum likelihood (ML) decoding requires a joint detection of three real symbols,(More)
High voltage generators are being subject to higher voltage rating and are being designed to operate in harsh conditions. Stator windings are the main component of generators in which Electrical, magnetically and thermal stresses remain major failures for insulation degradation accelerated aging. A large number of generators failed due to stator winding(More)
Optimal selection of electrical insulations in electrical machinery insures reliability during operation. From the insulation studies of view for electrical machines, stator is the most important part. This fact reveals the requirement for inspection of the electrical machine insulation along with the electro-thermal stresses. In the first step of the(More)
High voltage generators are being subject to higher voltage rating and are being designed to operate in harsh conditions. Stator windings are the main component of generators in which Electrical, magnetical and thermal stresses remain major failures for insulation degradation accelerated aging. A large number of generators failed due to stator winding(More)
The prevalence of migraine in the world is about 15 and 7% among women and men, respectively. The purpose of this study was comparison of somatoform dissociation, fatigue severity and pain behavior in patients with migraine headache and its relationship with coping strategies. This descriptive analytical study has been done on 120 patients with migraine(More)
Background and Purpose. Trauma is the leading cause of death for youth in developing countries. Given the prevalence of head trauma (HT) in society and its complication and burden, the epidemiologic study of head trauma is necessary and is the main aim of this study. Materials and Methods. This retrospective population-based survey describes the(More)
We propose a new and efficient algorithm to detect, identify, and correct measurement errors and branch parameter errors of power systems. A dynamic state estimation algorithm is used based on the Kalman filter theory. The proposed algorithm also successfully detects and identifies sudden load changes in power systems. The method uses three normalized(More)
Introduction: Stroke is one of the neurologic diseases and the third common causes of death in USA after cancer and heart disease. Two-thirds of strokes occur in developing countries and people up 65 years old. Based on WHO report, the country Iran with 97.4 deaths per 100000 is in the 90th ranking between world countries. The aim of this study was(More)
