16. Contribution to Wideband SAR Space-Time Processing, and Radar Remote Sensing of Sea Ice
Sammanfattning : Synthetic Aperture Radar (SAR) has the capability to map the Earth with high resolution and is used in both civilian and military applications. The development of SAR systems is going towards higher resolution. Today there are Wide Band (WB) SAR instruments that have a resolution actually smaller than the operating wavelength. LÄS MER
17. On Spectral Estimation and Bistatic Clutter Suppression in Radar Systems
Sammanfattning : Target detection serve as one of the primary objectives in a radar system. From observations, contaminated by receiver thermal noise and interference, the processor needs to determine between target absence or target presence in the current measurements. LÄS MER
18. Separation of Water and Fat Signal in Magnetic Resonance Imaging : Advances in Methods Based on Chemical Shift
Sammanfattning : Magnetic resonance imaging (MRI) is one of the most important diagnostic tools of modern healthcare. The signal in medical MRI predominantly originates from water and fat molecules. LÄS MER
19. Large Eddy Simulation of Turbulent Compressible Jets
Sammanfattning : Acoustic noise pollution is an environmental aggressor in everyday life. Aero- dynamically generated noise annoys and was linked with health issues. It may be caused by high-speed turbulent free flows (e.g. LÄS MER
20. Synaptic uncoupling in the mouse cochlea induced by noise or cisplatin and its clinical relevance
Sammanfattning : The cochlea has an autonomous circadian clock that controls auditory function and increases vulnerability to noise trauma during the active phase. The mechanisms regulating the circadian control of the auditory system are poorly understood. LÄS MER
