The TTCAN protocol is a new development in CAN technology that specifies a time-slot based communication mechanism. TTCAN technology avoids the transmission collisions commonly found in standard CAN networks. In TTCAN, all the message instances are transmitted only on previously allocated time-slots. No other instance may be transmitted on an allocated(More)
Real-time image processing requires high computational and I/O throughputs obtained by use of optoelectronic system solutions. A novel architecture that uses focal-plane optoelectronic-area I/O with a fine-grain, low-memory, single-instruction-multiple-data (SIMD) processor array is presented as an efficient computational solution for real-time(More)
STUDY OBJECTIVES To review the clinical characteristics and the pathogenesis of negative pressure pulmonary edema, and to determine its incidence in surgical patients. DESIGN Retrospective case-report study. SETTING Operating room, postanesthesia care unit and surgical intensive care of a teaching hospital. PATIENTS 30 surgical adult ASA physical(More)
A novel inverse CeO(2)/CuO catalyst for preferential oxidation of CO in H(2)-rich stream (CO-PROX) has been developed on the basis of a hypothesis extracted from previous work of the group (JACS 2007, 129, 12064). Possible separation of the two competing oxidation reactions involved in the process (of CO and H(2), respectively) is the key to modulation of(More)
The wide use of fieldbus based distributed systems in embedded control applications triggered the research on the problem of transmission network induced jitter in control variables. In this paper we introduce a variant of the classical Genetic Algorithm, which we call Progressive Genetic Algorithm, and show how it can be used to reduce jitter suffered by(More)
DESIGN PROBLEMS The paper discusses some new hardware and software tools that can be used for the design of virtual circuits based on dynamically reconfigurable FPGAs. With the aid of these tools we can implement a system that requires some hardware resources R c , on available hardware that has resources R h , where R c >R h. The main idea of the approach(More)
Urea (CH 6 ON 2) is one of the main human nitrogen-based metabolic wastes. The concentration of urea in blood lies between 2.5–7 mM for healthy individuals, and is commonly used as an indicator for several diseases that may alter this value. Spectrophotometric methods are employed for the determination of blood urea concentration during clinical assays.(More)
A computer vision camera prototype for real-time applications has been developed. The camera integrates a CMOS image sensor, an FPGA based coprocessing card, and an embedded PC for communication and control tasks. The system is targeted to computer vision tasks where low level processing and feature extraction can be implemented in the PPGA device. The PPGA(More)
