BACKGROUND The assessment of falls in the elderly has moved from disease-oriented approaches, which attempt to identify single causative factors, to performance-oriented evaluations of functional deficits. This study examined the abilities of elderly fallers and nonfallers to perform various functional activities and to provide some rationale for performance differences by assessing the integri...

In this paper we describe IoTCloud, a platform to connect smart devices to cloud services for real time data processing and control. A device connected to IoTCloud can communicate with real time data analysis frameworks deployed in the cloud via messaging. The platform design is scalable in connecting devices as well as transferring and processing data. With IoTCloud a user can develop real tim...

The central detectors of the ALICE experiment at LHC will produce a data size of up to 75 MB=event at an event rate p200 Hz resulting in a data rate of B15 GB=s: Online processing of the data is necessary in order to select interesting (sub)events (‘‘High Level Trigger’’), or to compress data efficiently by modeling techniques. Processing this data requires a massive parallel computing system (...

An increasing number of embedded system solutions in space, military, and consumer electronics applications rely on processor cores inside reconfigurable logic devices. Ensuring data integrity and confidentiality is of the utmost importance in many such applications. This paper describes a practical implementation of security extensions for embedded systems built around soft-core processors. Th...

Numerical algorithms have two kinds of costs: arithmetic and communication, by which we mean either moving data between levels of a memory hierarchy (in the sequential case) or over a network connecting processors (in the parallel case). Communication costs often dominate arithmetic costs, so it is of interest to design algorithms minimizing communication. In this paper we first extend known lo...
