In this thesis, we address the problem of locating a passive target using a multiple-input multiple-output (MIMO) radar with widely separated antennas (WSA). Using a WSA geometry, the spatial diversity of the transmit and receive antennas are utilized to improve the localization accuracy. First, common numerical algorithms are examined, including the Newton-Raphson (NR) method with the maximum lik

Introduction and aim: In SPECT imaging, the finite spatial resolution of the imaging system leads to a blurring of the reconstructed image. Consequently, counts originating from each point in the source distribution will be spread out over a volume in the reconstructed image, leading to spill-over of counts between different structures and distortion of the apparent activity concentration. This pr

OBJECTIVE: To evaluate a system for delivery of inhaled nitric oxide.DESIGN: Prospective, laboratory study.SETTING: Engineering laboratory.SUBJECTS: A standard ventilator (Servo Ventilator 300), supplemented with extra gas modules for nitric oxide delivery.INTERVENTIONS: Two ventilator-integrated gas modules, delivering < or = 10 parts per million (ppm) or < or = 100 ppm of nitric oxide, were used

BackgroundApproximately 15 % of surgical patients in hospital are affected of an adverse event, which is a medical error caused by the health care system. Laparoscopy is the preferred surgical technique in common procedures. Societal changes with shorter working hours, patient safety and ethics demand optimisation of resources toachieve the goal of educating competent surgeons within a reasonable

Chloride anations of PtCl5H2O−, trans-PtCl4(H2O)2 and trans-Pt(CN)4ClH2O− in the presence of PtCl42− have been studied at 50°C in 1.00M perchloric acid medium. It is shown that PtCl5H2O− is formed as the primary reaction product in the two last-mentioned anations. This is not compatible with the generally used mechanism for platinum(II)-catalyzed platinum (IV) substitutions, which gives PtCl62− as

A key message from this chapter - and the book as such - is that the Nordic Barnahus model is a step in the right direction in terms of meeting victimised children's needs and legal rights, and that it could be recommended as a promising practice for other countries. At the same time, it is not a quick fix. In light of the book contributions, this chapter discusses the potentials and challenges of

III-V compound materials have long been used in RF applications in high-electron-mobility-transistors (HEMTs) and bipolar-junction-transistors (BJTs). Now, III-V is also being viewed as a material candidate for replacing silicon in the n-channel in CMOS processes for increased drive currents and reduced power consumption in future nodes. Another alternative to increase the drive current is to use
