Roadmap on signal processing for next generation measurement systems

Signal processing is a fundamental component of almost any sensor-enabled system, with a wide range of applications across different scientific disciplines. Time series data, images, and video sequences comprise representative forms of signals that can be enhanced and analysed for information extraction and quantification. The recent advances in artificial intelligence and machine learning are shifting the research attention towards intelligent, data-driven, signal processing. This roadmap presents a critical overview of the state-of-the-art methods and applications aiming to highlight future challenges and research opportunities towards next generation measurement systems. It covers a broad spectrum of topics ranging from basic to industrial research, organized in concise thematic sections that reflect the trends and the impacts of current and future developments per research field. Furthermore, it offers guidance to researchers and funding agencies in identifying new prospects.AerodynamicsMicrowave Sensing, Signals & System

NASA SBIR abstracts of 1990 phase 1 projects

The research objectives of the 280 projects placed under contract in the National Aeronautics and Space Administration (NASA) 1990 Small Business Innovation Research (SBIR) Phase 1 program are described. The basic document consists of edited, non-proprietary abstracts of the winning proposals submitted by small businesses in response to NASA's 1990 SBIR Phase 1 Program Solicitation. The abstracts are presented under the 15 technical topics within which Phase 1 proposals were solicited. Each project was assigned a sequential identifying number from 001 to 280, in order of its appearance in the body of the report. The document also includes Appendixes to provide additional information about the SBIR program and permit cross-reference in the 1990 Phase 1 projects by company name, location by state, principal investigator, NASA field center responsible for management of each project, and NASA contract number

Diffusion-weighted magnetic resonance imaging in diagnosing graft dysfunction : a non-invasive alternative to renal biopsy.

The thesis is divided into three parts. The first part focuses on background information including how the kidney functions, diseases, and available kidney disease treatment strategies. In addition, the thesis provides information on imaging instruments and how they can be used to diagnose renal graft dysfunction. The second part focuses on elucidating the parameters linked with highly accurate diagnosis of rejection. Four parameters categories were tested: clinical biomarkers alone, individual mean apparent diffusion coefficient (ADC) at 11-different b- values, mean ADCs of certain groups of b-value, and fusion of clinical biomarkers and all b-values. The most accurate model was found to be when the b-value of b=100 s/mm2 and b=700 s/mm2 were fused. The third part of this thesis focuses on a study that uses Diffusion-Weighted MRI to diagnose and differentiate two types of renal rejection. The system was found to correctly differentiate the two types of rejection with a 98% accuracy. The last part of this thesis concludes the work that has been done and states the possible trends and future avenues

Advancements and Breakthroughs in Ultrasound Imaging

Ultrasonic imaging is a powerful diagnostic tool available to medical practitioners, engineers and researchers today. Due to the relative safety, and the non-invasive nature, ultrasonic imaging has become one of the most rapidly advancing technologies. These rapid advances are directly related to the parallel advancements in electronics, computing, and transducer technology together with sophisticated signal processing techniques. This book focuses on state of the art developments in ultrasonic imaging applications and underlying technologies presented by leading practitioners and researchers from many parts of the world

Role of angiogenic factors and circulating monocytes in the pathogenesis of preeclampsia and intrauterine fetal growth restriction

A collection of studies into the pathogenesis of preeclampsia (PE) and intrauterine fetal growth restriction (IUGR) are presented, focusing on factors involved in the angiogenesis as well as maternal factors such as circulating monocytes and lipid status. Placental expression of PlGF and KDR were significantly reduced in IUGR Adescription of digital image analysis techniques in the assessment of angiogenic factor expression in the placenta is presented. The study on circulating angiogenic factors showed elevated sFlt-1 and sEndoglin and low PlGF in preeclampsia and IUGR. Pro and anti-angiogenic factors and their ratios were assessed as biomarkers for pathological pregnancies. Maternal and fetal monocyte phenotype and polarization were examined inPE and IUGR. Ahigher percentage of intermediate and non-classical monocytes were found in PE and IUGR. Evaluation of inflammatory and healing monocyte phenotypes showed a shift towards healing phenotype in IUGR. The maternal and fetal triglyceride levels were higher in preeclampsia. This study documented the first description of elevated Apo lipoprotein B levels in cord blood at delivery in PE and IUGR. This research contributes to the literature on pathogenesis of preeclampsia and intrauterine growth restriction, demonstrating similarities and differences between the conditions which has lead us closer towards understanding their pathogenesis
