accuracy of inertial navigation system (ins) is limited by inertial sensors imperfections. before using inertial sensors signals in the data fusion algorithm, noise removal method should be performed, in which, wavelet decomposition method is used. in this method the raw data is decomposed into high and low frequency data sets. in this study, wavelet multi-level resolution analysis (wmra) techn...

Nowadays GPS is widely used to monitor the ionosphere. However, the current results from ground-based GPS observations only provide some information on the horizontal structure of the ionosphere, and are extremely restricted in mapping its vertical structure. In this paper, tomography reconstruction technique was used to image 3D ionospheric structure with ground-based GPS. The first result of ...

GPS Receivers are used for both military and civilian applications. This paper presents the GPS Receiver for System on Chip (SoC) application. In this paper the GPS Receiver is been implemented as System on Chip in FPGA board. VHDL modeling for the back end of GPS Receiver is designed. As baseband signal processing is the main aspect in the GPS receiver, it is achieved by this software GPS Rece...

BACKGROUND Several studies have shown that general practitioners (GPs) under-diagnose common mental disorders, and that training courses hardly improve this practice. The influence of GPs' self-perceived ability to recognize the severity of such disorders on these facts has not been investigated. This study explores: 1) GPs' perceived ability to recognize major depressive episode (MDE) and gene...

BACKGROUND Breastfeeding is considered the best infant-feeding method. Norway is one of the leading countries in terms of breastfeeding initiation and duration. To maintain this high breastfeeding rate, it is important to understand the factors that influence breastfeeding. A doctor s advice can improve the rates of breastfeeding initiation and duration, but not all doctors are competent in bre...

OBJECTIVE Nausea and vomiting during pregnancy (NVP) is very common, and may have great impact on a woman's life. The aim of this study was to explore thoughts and attitudes among Norwegian pregnant women and GPs on treatment of NVP and pregnancy care. DESIGN Focus-group study. SETTING AND SUBJECTS Separate focus-group discussions were conducted with pregnant women and GPs. RESULTS Two fo...
