Shunt

control for the UPFC is such that the series converter of the UPFC controls the transmission line near the micro grid real/reactive power flow and the shunt converter of the UPFC controls the UPFC bus voltage/shunt reactive power and the DC link capacitor voltage. In steady state, the real power demand of the series converter is supplied by the shunt converter of the UPFC. To avoid instability/loss of DC link capacitor voltage during transient conditions, a new real power coordination controller has

ratio and mildly elevated intraocular pressures in each eye. Intraocular pressure was maintained in the mid-teens bilaterally on topical glaucoma monotherapy. At 4 years of age, he relocated. When he was 5-years-old, he underwent bilateral glaucoma shunt placement elsewhere The operative reports and glaucoma drainage implant (GDI) specifics were not obtainable. No prior or subsequent ocular surgeries were performed. He returned to our care after 2 years. His eye pressures were controlled without

Assignment. Task 3.1 a) The magnetic field of a permanent magnet causes the atoms to move around uniformly in the same direction. This may vary depending on the electrons of the atoms causing a variety of atoms to be able to do this and few which can hold a permanent magnetic field. It is an invisible field and it is also called a vector because of the forces specified direction and magnitude. The arrow displays the direction of the force and also how the forces are. The closer the lines are

not reach statistical significance. This correlates well with other studies. In the study by Dorai Z et al., the mean age for the study population was 53.2 years (range, 17–89 years). The median age for the shunt-treated population was 60 years, in comparison with 51 years for the non shunt-treated population. The authors stated a possible explanation; older patients have wider subarachnoid spaces which can hold larger amounts of subarachnoid blood, thus increasing their risk of developing CSF circulation

The Lumbar-peritoneal shunt is inserted into the Subarachnoid cavity between two of the vertebrae in the lumbar region of the spine. This cavity also is referred to as the Subarachnoid space. The cavity is a spongy, tissue-filled area that surrounds the brain and spinal cord, and it contains the cerebrospinal fluid (CSF). The shunt is placed under the skin, and it continues around the oblique muscles on one side of the body. The shunt ends at the peritoneal cavity in the abdominal

condition due to the abnormal shape the head takes. The head becomes swollen and large due to the excessive amount of cerebrospinal fluid that will not drain properly. Currently there is only two ways to treat this condition and that is by installing a shunt or preforming an Endoscopic Third ventriculostomy. Some people oppose the thought of the endoscopic third ventriculostomy because, it is not the common way to treat the condition. Even though this treatment is up and coming, it is a more effective

Results Over a period of 4 years, 10 patients (6 men and 4 women) with abdominal complications of VP shunt catheter were managed. Their ages at operation were ranged from 10 months to 17 years (table 1). All patients were investigated, diagnosed and managed laporoscopically. The median operative time of the laparoscopic procedure varied according to the diagnosis. It was 120 minutes in abdominal pseudocysts, 45 minutes in recurrent congenital inguinal hernias, 100 minutes in adhesive intestinal

pressure. In other words, blood flows from the left ventricle to the right ventricle, hence the name left-to-right shunt. There are various degrees of severity for this disease by having either a small or large shunt. Patients with a small shunt are asymptomatic and their life prognosis is very optimistic compared to those with a large shunt. In the latter case, a medium to large shunt increases pulmonary blood flow, which causes pulmonary disease and may cause cardiac failure. This congenital heart

CHAPTER 1 INTRODUCTION 1.1 Introduction An increasing demand for high quality, reliable electrical power and increasing number of distorting loads may leads to an increased awareness of power quality both by customers and utilities. The most common power quality problems today are voltage sags, harmonic distortion and low power factor. Voltage sags is a short time (10 ms to 1 minute) event during which a reduction in r.m.s voltage magnitude occurs. It is often set only by two parameters, depth/magnitude

quality conditioner (UPQC) which is an integration of shunt and series Active Power Filters and aims to compensate for voltage sag, voltage and current unbalance and other power quality problems [1],[5],[6]. The UPQC helps to improve power quality at the point of installation on power distribution system or industrial power system. This paper deals with design of UPQC by considering a controller based on PQ theory. Reference signal generation for shunt active filter is done by using PQ theory while for
