Advances in the development of micro-electromechanical systems (MEMS) have made possible the fabrication of cheap and small dimension accelerometers and gyroscopes, which are being used in many applications where the global positioning system (GPS) and the inertial navigation system (INS) integration is carried out, i.e., identifying track defects,(More)
INTRODUCTION The objective of this study was to evaluate the management of community acquired pneumonia (CAP) according to conventional clinical criteria applied in the emergency room as compared to a pneumonia prognosis index (PPI) (Fine et al. NEJM 1997). We also analyzed which factors were associated with the need for inpatient treatment in PPI risk(More)
The combined problems of changing work schedules and work places are not uncommon in military operations. For example, during the Persian Gulf War, many military units underwent short notice transmeridian deployment with immediate commencement of 24-h operations upon arrival. Some of these individuals likely suffered from circadian desynchronosis, blunting(More)
The LLDFT rules used in this work allow to avoid some hard to detect faults or even undetectable faults on a cell library by modifying the cell layout whithout changing their behaviour and achieving a good level of reliability. These rules avoid some open faults or reduce their appearance probability. The main purpose has been to apply that set of LLBFT(More)
Dynamic Partial Reconfiguration (DPR) allows modification of certain parts of an FPGA while the rest of the device continues to operate and remains unaffected by the partial reprogramming. DPR for FPGA-based designs is an increasingly important feature in many systems that must adapt quickly to changing run-time requirements. Particularly in aerospace(More)
The huge computational complexities involved with particle filters is known to be one of the major constraint to their widespread use for different real time applications. This paper analyzes the computational complexities of the sampling, importance weight and resampling steps for the two most popular types of particle filters; generic particle filter and(More)
