The Flexible Query Processor (FQP) constitutes a family of hardware-based data stream processors that support dynamic changes to queries and streams, as well as static changes to the processor-internal fabric in order to maximize performance for given workloads. FQP is prototyped on field-programmable gate arrays (FPGAs). To this end, FQP supports select,(More)
In this paper, we present a real-time capable event-based system, which is tailored towards analytical query processing in the context of soccer games. The main challenge is to meet the application's strict real-time and low-latency requirements in face of streams of high-velocity sensor data. We describe a workflow-like architecture for query processing(More)
BACKGROUND Status epilepticus (SE) is a type of persistent lasting seizure with high mortality and morbidity. Numerous medications are suggested for the treatment of SE, two of which are sodium valproate and phenytoin. The purpose of this study is to conduct a comparison between the efficiencies of intravenous sodium valproate and phenytoin in the treatment(More)
There is a rising interest in accelerating stream processing through modern parallel hardware, yet it remains a challenge as how to exploit the available resources to achieve higher throughput without sacrificing latency due to the increased length of processing pipeline and communication path and the need for central coordination. To achieve these(More)
BACKGROUND Neurotoxicity side effects related to cyclosporine kinetics could lead to dysfunction of kidney graft and patient outcome after transplantation. The aim of this study was evidence-based pharmacotherapy of kidney transplant recipients and to investigate neurotoxic levels of Iminoral. MATERIALS AND METHODS The results of 2239 cyclosporine trough(More)
BACKGROUND Catamenial epilepsy is a kind of epilepsy, known in this name, when the periodicity of the exacerbation of the seizure is in association with menstural cycle. The present study examined the progesterone effectiveness as a complementary treatment in women with intractable catamenial epilepsy. MATERIALS AND METHODS The present study was conducted(More)
