There are two main classes of methods for checking universality and language inclusion of Büchi-automata: Rank-based methods and Ramsey-based methods. While rank-based methods have a better worst-case complexity, Ramsey-based methods have been shown to be quite competitive in practice [9, 8]. It was shown in [9] (for universality checking) that a simple subsumption technique, which avoids explo...

Traditionally, the Worst-Case Execution Time (WCET) of Embedded Software has been estimated using analytical approaches. This is effective, if good models of the processor/Systemon-Chip (SoC) architecture exist. Unfortunately, modern high performance SoCs often contain unpredictable and/or undocumented components that influence the timing behaviour. Thus, analytical results for such processors ...

To derive safe bounds on worst-case execution times (WCETs), all components of a computer system need to be time-predictable: the processor pipeline, the caches, the memory controller, and memory arbitration on a multicore processor. This paper presents a solution for timepredictable memory arbitration and access for chip-multiprocessors. The memory network-onchip is organized as a tree with ti...

Modern embedded applications usually have real-time constraints and they are implemented using heterogeneous multiprocessor systems-on-chip. Dimensioning a system requires accurate estimations of the worst-case execution time (WCET). Overestimation leads to over-dimensioning. This paper introduces a method for automatic discovery of scenarios that incorporate correlation between different parts...

A common goal in Reinforcement Learning is to derive a good strategy given a limited batch of data. In this paper, we adopt the safe policy improvement (SPI) approach: we compute a target policy guaranteed to perform at least as well as a given baseline policy. Our SPI strategy, inspired by the knows-what-it-knows paradigms, consists in bootstrapping the target policy with the baseline policy w...

Absence of the sternum or asterniais the rarest developmental anomaly of the stern um. A female newborn is presented with asternia and ASD.

Trichoadenoma is a rare skin tumor first described by Nikolowski. There are variable clinical features and tumors have been diagnosed as cysts, basal cell epithelioma and seborrheic keratosis. The microscopic feature mainly consists of numerous cysts surrounded by eosinophilic cells. Trichoadenoma is benign and treatment is by simple excision. We report a case of trichoadenoma on the nose...

Spondylolisthesis has always fascinated orthopaedist and others concerned with the treatment of low back disease. Spondylo means Vertebra and Olisthesis to slip or slide down a slippery path.In this orticle.the history of spondylolisthesis has been described,followed by the recent classification of different types of the condi­tion.There are Sdifferent types of spondylolisthesis­dysplastic,Isth...

A four day old female infant was admitted because of poor feeding, vomiting and jaundice. Laboratory examination showed hyperkalemia, mild hyponatremia and renal tubular acidosis type 4. Serum aldosterone and plasma renin activity were elevated but serum cortisol, 17 -hydroxyprogesterone, ACTH, 24 hour urinary 17- ketoste roid, pregnanetriol, renal function and sonogram were normal and henc...
