طراحی و ساخت آنتن از مهمترین مباحث در زمیه مخابرات موج است که ساخت آنتن فرستندهˆگیرنده ثابت رادیو سیار نیز به عنوان اولین و یکی از مهمترین بخش ها در این زمینه قرار می گیرد. بدین ترتیب در این پایان نامه در بخش تئوری نخست تحلیلی از آرایه های دو قطبی در مقابل صفحه نامحدود توسط روش های معمول تصویر انجام می شود، سپس همان آرایه در مقابل صفحه محدود قرار گرفته و توسط روش ممان تحلیل می شود. به عنون آخری...
Urine cultures represent one of the most commonly submitted specimens to a microbiology laboratory. In an attempt to manage effectively this type of specimen, Bac-T-Screen (BTS), nitrate and leukoestrase test were performed on all clean catch urine specimens sent for culture. Three hundred and four specimens were screened by these methods. The BTS, by itself, had the highest sensitivity, and sp...
The relative stability of base transceiver station (BTS) clocks in cellular networks is studied. It is demonstrated that although BTS clocks are not perfectly synchronized to GPS, they are relatively stable with respect to each other, permitting exclusive navigation with cellular signals in the absence of global navigation satellite system (GNSS) signals. A navigation observable is developed le...
GSM Network Designs usually offers big challenges for achieving an efficient cost while respecting the complex combinatorial technical constraints. This networks have hundred or thousands BTS. They have their traffic grouped in hubs, then in BSC nodes to reach the MSC. Hubs must be elected within the BTS set and BSC nodes have to be geographically allocated in the available sites. Also, the num...
A significant step towards improving care of patients with non-cystic fibrosis bronchiectasis was the creation of the British Thoracic Society (BTS) national guidelines and the quality standard. A BTS bronchiectasis audit was conducted between 1 October and 30 November 2012, in adult patients with bronchiectasis attending secondary care, against the BTS quality standard. Ninety-eight institutio...
Background and Objectives: with the developments of technology, contact with various frequencies of electromagnetic fields ( EMF ) has significantly increased, while the abundant benefits of using microwaves in routine life cannot be neglected. During recent years there have been reports of adverse effects caused by contact with electric and magnetic fields of these waves that spread from BTS a...
BACKGROUND Accurate spirometry is important in the management of COPD. The UK Quality and Outcomes Framework pay-for-performance scheme for general practitioners includes spirometry related indicators within its COPD domain. It is not known whether high achievement against QOF spirometry indicators is associated with spirometry to BTS standards. METHODS Data were obtained from the records of ...
Iron uptake and metabolism are tightly regulated in both plants and animals. In Arabidopsis (Arabidopsis thaliana), BRUTUS (BTS), which contains three hemerythrin (HHE) domains and a Really Interesting New Gene (RING) domain, interacts with basic helix-loop-helix transcription factors that are capable of forming heterodimers with POPEYE (PYE), a positive regulator of the iron deficiency respons...
: Radio Resource optimization on the three sectors (A, B, and C) of a BTS belonging to ZTE ZXG-10 BSS system was carried out adopting Ajay (2004) processes. The preprocessing raw data was obtained through the use of Ericsson TEMs Phones incorporated with GPS tool for location updates during the Drive Test (DT). The post-processing of the DT data was done by Actix Analyzer Service Verification S...
