1. Key Data for the Reference and Relative Dosimetry of Radiotherapy and Diagnostic and Interventional Radiology Beams
Sammanfattning : Accurate dosimetry is a fundamental requirement for the safe and efficient use of radiation in medical applications. International Codes of Practice, such as IAEA TRS-398 (2000) for radiotherapy beams and IAEA TRS-457 (2007) for diagnostic radiology beams, provide the necessary formulation for reference and relative dosimetry and the data required for their implementation.

2. Design and Identification of Wireless Transmitters for a Low-power and Secure Internet of Things
Sammanfattning : Wireless communication is a key enabler for connecting billions of Internet of Things devices. For networked embedded devices operating on limited energy resources, wireless communication dominates the power consumption. LÄS MER
3. On Surface Characteristics and Microstructural Development of Soft Magnetic Composite Powder and Components
Sammanfattning : Soft Magnetic Composite (SMC) products manufactured by traditional Powder Metallurgical (PM) techniques, are strong candidate materials for electromagnetic applications. Their advantages are based on cost and energy efficient production methods, shape complexity realization and uniquely uniform and isotropic three dimensional (3D) magnetic properties. LÄS MER
4. Use of localised techniques to elucidate the influence of process variables on the corrosion of stainless steels
Sammanfattning : Several factors during steel manufacture and fabrication can alter the passivity and corrosion behaviour of stainless steels. These include alloying, deformation, welding and heat treatments. LÄS MER
5. Modelling and Retrieval of Forest Parameters from Synthetic Aperture Radar Data
Sammanfattning : Currently, one of the most uncertain factors in the global carbon cycle models lies in the terrestrialcarbon stock, mainly forests. The available methods for global forest resource mapping provide onlyrough estimates of biomass, the most relevant practical quantity related to carbon stock. LÄS MER
