موقعیت یابی و نقشه سازی همزمان (slam) مشکلی اساسی در زمینه ناوبری ربات های متحرک است و حل آن یکی از جذاب ترین موضوعات کاری محققین بوده است وامروزه یکی از بخش های مهم سیستم های ناوبری را تشکیل می دهد. در این مقاله یک الگوریتم slam اینرسی کارآمد برای یک پهپاد یا یک وسیله هوابرد ارائه می شود. ساختار slam اینرسی مذکور برای بکارگیری دو نوع سنسورrange/bearing و bearing-only مناسب بوده و نیازی به سیست...
امروزه استفاده از شبکه های حسگر گسترش پیدا کرده است. و بسیاری از تحقیقات پیرامون شبکه های حسگر می باشند. یکی از موضوعات رایج در تحقیقات مکانیابی می باشد. مکانیابی به تشخیص اتوماتیک مکان گره هایی که مجهز به سیستم مکانیابی سراسری (gps) نیستند، گفته می شود، یکی از تکنیک هایی که برای مکانیابی در شبکه های حسگر از آن استفاده می شود، مقیاس پذیری چندبعدی است، چندین الگوریتم متمرکز و تنها یک الگوریتم تو...
OBJECTIVE To explore how a group of Swedish general practitioners (GPs) manage patients with a sore throat in relation to current guidelines as expressed in interviews. DESIGN Qualitative content analysis was used to analyse semi-structured interviews. SETTING Swedish primary care. SUBJECTS A strategic sample of 25 GPs.

BACKGROUND Disease prevention and health promotion are important tasks in the daily practice of all general practitioners (GPs). The objective of this study was to explore the knowledge and attitudes of European GPs in implementing evidence-based health promotion and disease prevention recommendations in primary care, to describe GPs' perceived barriers to implementing these recommendations and...
BACKGROUND The criteria used when GPs submit stool specimens for microbiological investigation are unknown. AIM To determine what criteria GPs use to send stool specimens, and if they are consistent with national guidance, and whether GPs would prescribe an antibiotic before they receive a result. DESIGN AND SETTING Questionnaire survey of 974 GPs in 172 surgeries in England. METHOD GPs w...
The purpose of the present retrospective study was to investigate whether a score reflecting systemic inflammatory processes [the Glasgow Prognostic Score (GPS)] provides relevant information for radiation oncologists. GPS is a three-tiered score [0: normal C-reactive protein (CRP) and albumin; 1: one abnormal result; 2: increased CRP and low albumin]. Correlations between disease type and exte...
BACKGROUND Sexual problems are common among people with coronary heart disease and can adversely affect patients' quality of life. GPs are ideally placed to deal with these problems. Research suggests that GPs are reluctant to address sexual problems but little is known about what currently takes place in practice. The aim of this study was to examine GPs' self-reported behaviour and attitudes ...
The humoral immunization potential of panax ginseng polysaccharide (GPS) against H9N2 avian influenza virus (H9N2 AIV) in chickens was investigated. The effects of GPS treatment before and during H9N2 AIV infection were determined in chicken embryo fibroblast (CEF) by MTT (3(4, 5-dimethylthiazol-2-yl)-2, 3-diphenyl tetrazolium bromide) assays and quantitative RT-PCR analysis of MHC and cytokine...
The Unmanned Aerial Vehicles (UAV) positioning in the outdoor environment is usually done by the Global Positioning System (GPS). Due to the low power of the GPS signal at the earth surface, its performance disrupted in the contaminated environments with the jamming attacks. The UAV positioning and its accuracy using GPS will be degraded in the jamming attacks. A positioning error about tens of...
BACKGROUND Little is known about pressure from patients or relatives on physician's decision making of continuous palliative sedation. We aim to describe experienced pressure by general practitioners (GPs) in cases of continuous sedation after the introduction of the Dutch practice guideline, using a questionnaire survey.
