Aims: Postural orthostatic tachycardia syndrome (POTS) is a type of chronic orthostatic intolerance, annually affecting around 500,000 young Americans. Symptoms of POTS include lightheadedness and persistent increase in heart rate with upright body posture [1-3]. It requires a medical diagnosis. Impaired cerebral oxygenation of patients with POTS has been reported [4]. The pathophysiology remains unclear, and research is needed to understand the underlying conditions that lead to POTS. The aim of this research is to …
A Battery-Operated Portable Standard Lead Ecg Monitor With Abnormal Heart Condition Detection System For Dogs, Zichen He
Theses and Dissertations
Long term monitoring the dog's heart condition is the best way to prevent being unable to treat the dog's heart failure in time when it occurs. Although, electro-cardio activity has been discovered by French scientist Mattencci in 1842, but there hasn't been any proper device developed so far for long term ECG (electrocardiogram) monitoring of cardiac dogs. Therefore, this paper has proposed an ECG monitor specially designed for dogs to fill this gap. The ECG monitor proposed is a 3-lead ECG monitoring system with diagnosis software that can detect heart failure, tachycardia, bradycardia, and arrhythmia according to dog's ECG signal. …
Dc Line-Interactive Uninterruptible Power Supply (Ups) With Load Leveling For Constant Power And Pulse Loads, Seyed Ahmad Hamidi
Dc Line-Interactive Uninterruptible Power Supply (Ups) With Load Leveling For Constant Power And Pulse Loads, Seyed Ahmad Hamidi
Theses and Dissertations
Uninterruptable Power Supply (UPS) systems are usually considered as a backup power for electrical systems, providing emergency power when the main power source fails. UPS systems ensure an uninterruptible, reliable and high quality electrical power for systems with critical loads in which a continuous and reliable power supply is a vital requirement.
A novel UPS system topology, DC line-interactive UPS, has been introduced. The new proposed UPS system is based on the DC concept where the power flow in the system has DC characteristic. The new DC UPS system has several advantageous with respect to the on-line 3-phase UPS which …
Automatic Analysis Of Surface Electromyography Of Reflexes For Central Nervous System Inhibition During Pregnancy, Neda Parvin
Automatic Analysis Of Surface Electromyography Of Reflexes For Central Nervous System Inhibition During Pregnancy, Neda Parvin
Theses and Dissertations
Eclampsia is a life-threatening neurological complication (seizures or coma) of pregnancy, and represents progression of pre-eclampsia (high blood pressure and protein in the urine isolated to pregnancy). Even though the exact mechanism of pre-eclampsia and its neurological manifestations have yet to be definitively established, it is known that there is a loss of inhibitory impulses between the cerebral cortex and the spinal cord resulting in exaggerated reflexes. In this work, we establish normative measures for deep tendon reflexes (DTR) during pregnancy. We quantified the surface electromyogram (EMG) at the knee and ankle of DTRs in 279 subjects. The signals were …
