using pseudolites Use of GPS pseudolites now makes it possible to apply GPS navigation in an indoor environment. A pseudolite is a signal generator that transmits GPS-like signals to nearby users. In the United States, interest in pseudolite-based indoor navigation stems in part from imminent implementation of new automatic location capability in mobile cellular phones socalled Enhanced 911 or ...

OBJECTIVES To describe the management of vaginal discharge in general practice, with particular regard to the use of the high vaginal swab (HVS), and to compare GPs' expectations of this test with the processing and reporting undertaken by different laboratories. METHODS A postal questionnaire survey of 2146 GPs in the North Thames area and postal questionnaire study of the 22 laboratories se...

For large area surveillance, a number of UAVs are preferred. In such situation, navigation becomes a prime factor, which reduces the chance of collision. UAVs primarily depend on GPS, which has an order of inaccuracy. Conventional correction methods like differential GPS needs extra hardware and cannot improve stochastic errors like multipath error and receiver error. In this paper we demonstra...

BACKGROUND Parts of New Public Management-reforms of the public sector depend on introduction of market-like mechanisms to manage the sector, like free choice of hospital. However, patients may delegate the choice of hospital to agents like general practitioners (GPs). We have investigated which factors Danish GPs reported as decisive for their choice of hospital on behalf of patients, and thei...

Several studies have shown a close relationship between vegetation fertility and different vegetation indices extracted from satellite data. The vegetation fertility in Arctic is at overall scales highly related to temperature. At lower scales surface material, snow cover, hydrology and anthropogenic effects (geese, reindeer) are determinant in constituting the different vegetation communities....

Abstract RFC 1589 describes a UNIX kernel implementation model for high-precision time-keeping. This model is meant for use in conjunction with the Network Time Protocol (NTP, RFC 1305), or similar time synchronization proto...

Earlier this year the General Medical Council unveiled plans that would see GPs finally included on specialist register,1 recognising we’re specialists in general practice. The Royal College of Practitioners and BMA have actively campaigned for this,2 so perhaps I should be more pleased to hear news. Like most GPs, however, I’ve never been overly bothered by airs graces. This change professiona...
