background: health system research (hsr) is system planning, coordination, monitoring and management of research resources and activities to achieve health and justice. as the main members of the health system, general practitioners (gps) play an important role in access to health care goals. the aim of the present study was to assess knowledge, attitude, and performance of gps in rafsanjan, ir...
NAVSYS High Gain Advanced GPS Receiver (HAGR) uses a digital beam-steering antenna array to provide additional gain in the direction of the GPS satellite signals. This increases the received signal/noise ratio on the satellites tracked and also improves the accuracy of the pseudo-range and carrier-phase observations. The directivity of the digital beams created from the antenna array also reduc...
BACKGROUND In most countries with sickness insurance systems, general practitioners (GPs) play a key role in the sickness-absence process. Previous studies have indicated that GPs experience several tasks and situations related to sickness certification consultations as problematic. The fact that the organization of primary health care and social insurance systems differ between countries may i...
This paper shows a distributed object-oriented architecture to provide GPS data to GIS applications. Data captured in real time by GPS units are sent via radio to the computer. Several sources of this real data in addition to simulated GPS data are distributed in a computer network. These servers of GPS data can be accessed by distributed client applications. A CORBA based infrastructure provid...
Gyu-In Jee is an full Professor in the Department of Electronics Engineering at Konkuk University in Seoul, Korea. He received his Ph.D. in Systems Engineering from Case Western Reserve University. He has worked on several GPS related research projects; GPS receiver software design, GPS/INS integration for land vehicle, DGPS system development, GPS engine design using the Mitel chip sets, wirel...
We present interference analysis from Non-communication device which is used in many applications such as factory, home and hospital into Global Positioning System (GPS) Service. GPS service is used to detect location for car driving and safety of life. Nowadays, non-communication devices are increased rapidly. Therefore, in case that noncommunication device and GPS receiver are operated in clo...
This paper examines the performance of several precise point positioning (PPP) models, which combine dual-frequency GPS/Galileo observations in the un-differenced and between-satellite single-difference (BSSD) modes. These include the traditional un-differenced model, the decoupled clock model, the semi-decoupled clock model, and the between-satellite single-difference model. We take advantage ...
OBJECTIVE To determine how the timing and length of hospital discharge letters impact on the number of ongoing patient problems identified by general practitioners (GPs). TRIAL DESIGN GPs were randomised into four groups. Each viewed a video monologue of an actor-patient as he might present to his GP following a hospital admission with 10 problems. GPs were provided with a medical record as w...
Route taken and distance travelled are important parameters for studies of animal locomotion. They are often measured using a collar equipped with GPS. Collar weight restrictions limit battery size, which leads to a compromise between collar operating life and GPS fix rate. In studies that rely on linear interpolation between intermittent GPS fixes, path tortuosity will often lead to inaccurate...
GPS seismology uses convential geodetic models to analyze GPS data at high sampling rates, such as 1 Hz. GPS seismology results are shown for the Denali, San Simeon, Tokachi-oki, and Chuetsu earthquakes. Records for these earthquakes indicate that GPS is an excellent instrument for measuring large displacements near earthquake ruptures. GPS systems can be improved for seismic applications if th...
