In this paper manual parallelization is compared with parallelization using the Open Multi-Processing (OpenMP) software framework on an embedded eight core Digital Signal Processor (DSP) developed by Texas Instruments. In order to compare these two methods an in-house developed 2D image registration algorithm is parallelized. Furthermore considerations regarding the parallelization on this DSP are presented. Finally both parallelization methods in respect of performance and real time behavior are measured and analyzed. © 2013 IEEE. Source

We present a vision-based approach to ancient coins' identification. The approach is a two-stage procedure. In the first stage an invariant shape description of the coin edge is computed and matching based on shape is performed. The second stage uses preselection by the first stage in order to refine the matching using local descriptors. Results for different descriptors and coin sides are combined using naive Bayesian fusion. Identification rates on a comprehensive data set of 2400 images of ancient coins are on the order of magnitude of 99%. © 2010 Springer-Verlag. Source

The paper deals with intra-vehicle ranging based on the time of arrival technique. The aim of the presented work is to compare the ranging accuracy in the 3 to 11 GHz ultra-wide band and the 56 to 64 GHz millimeter wave band. The comparison is performed using channel impulse responses calculated from complex transfer functions using a windowed IFFT. The complex transfer functions are measured by a four port vector network analyzer for empty and occupied car scenarios. The obtained results are discussed and differences in ranging accuracy between both bands are explained by means of several reference measurements carried out in an anechoic chamber. © 2015 IEEE.

Expert Opinion on Drug Safety | Year: 2012

Introduction: The field of cardiac safety pharmacology has been experiencing exciting changes over the recent years. Drug induced arrhythmia of the torsade des pointes types has been the reason for the denial of approval of novel drug candidates. The aim of cardiac safety pharmacology is to detect undesirable pharmacodynamic drug effects within and above the therapeutic range. A special focus is on the identification of potential arrhythmogenic effects within the drug discovery chain. Areas covered: Here, the authors discuss the relevance of induced pluripotent stem (iPS) cell derived cardiomyocytes for safety pharmacology. The technology of obtaining functional cardiomyocytes from somatic cells of healthy donors and patients with inherited diseases is the basis for diverse disease models in multi-level safety pharmacology screening. The reader will gain an overview of stem cell based technologies in cardiac safety pharmacology in cardiac and disease modeling by iPS cell derived cardiomyocytes from patients with an inherited cardiac syndrome. Expert opinion: iPS cell derived cardiomyocytes especially from patients with increased risk of cardiac arrhythmia are on the verge of offering new options for drug testing. More reliable assays can be expected to predict the arrhythmogenic risk of drug candidates in humans. However, this technology is still new and extensive validation studies are due. © 2012 Informa UK, Ltd. Source

Background. The development of new wireless communication technologies that emit radio frequency electromagnetic fields (RF-EMF) is ongoing, but little is known about the RF-EMF exposure distribution in the general population. Previous attempts to measure personal exposure to RF-EMF have used different measurement protocols and analysis methods making comparisons between exposure situations across different study populations very difficult. As a result, observed differences in exposure levels between study populations may not reflect real exposure differences but may be in part, or wholly due to methodological differences. Methods. The aim of this paper is to develop a study protocol for future personal RF-EMF exposure studies based on experience drawn from previous research. Using the current knowledge base, we propose procedures for the measurement of personal exposure to RF-EMF, data collection, data management and analysis, and methods for the selection and instruction of study participants. Results. We have identified two basic types of personal RF-EMF measurement studies: population surveys and microenvironmental measurements. In the case of a population survey, the unit of observation is the individual and a randomly selected representative sample of the population is needed to obtain reliable results. For microenvironmental measurements, study participants are selected in order to represent typical behaviours in different microenvironments. These two study types require different methods and procedures. Conclusion. Applying our proposed common core procedures in future personal measurement studies will allow direct comparisons of personal RF-EMF exposures in different populations and study areas. © 2010 Röösli et al; licensee BioMed Central Ltd.
