We consider a good code for a discrete memoryless source with a specified distortion level to be one whose rate is close to the corresponding rate-distortion function and which, with large probability, reproduces the source within the allowed distortion level. We show that any good code must contain an exponentially large set of codewords, of effectively the same rate, which are all typical wit...

This paper addresses refinement and testing based on CSP models, when we distinguish input and output events. From a testing perspective, there is an asymmetry: the tester (or the environment) controls the inputs, and the system under test controls the outputs. The standard models and refinement relations of CSP are, therefore, not entirely suitable for testing. Here, we adapt the CSP stable-fa...

It is difficult to debug a program when the data set that causes it to fail is large (or voluminous). The cues that may help in locating the fault are obscured by the large amount of information that is generated from processing the data set. Clearly, a smaller data set which exhibits the same failure should lead to the diagnosis of the fault more quickly than the initial, large data set. We te...

The effects of thermoregulatory behaviours on gut blood flow in white sturgeon Acipenser transmontanus before and after feeding was studied using a blood flow biotelemetry system in combination with a temperature preference chamber. This is the first study to look at cardiovascular responses to feeding in white sturgeon, and also the first time behavioural tests in fish have been combined with ...

Methohexitone in doses of 2 mg/kg and 4 mg/kg was administered via a right atrial catheter to mechanically ventilated dogs lightly anaesthetized with trichloroethylene. The drug caused a significant initial increase in heart rate and a decrease in mean arterial pressure with both doses and a decrease in cardiac output. There was a significant reduction in myocardial blood flow, and myocardial o...

The design and implementation of a low power high speed differential signaling input/output (I/O) interface in 0.18um CMOS technology is presented. The motivations for smaller signal swings in transmission are discussed. The prototype chip supports 4 Gbps data rate with less than 10mA current at 1.8V supply according to Cadence Spectre post-layout simulations. Performance comparisons between th...

The omega network has various attractive topological properties. It supports both one-to-one message routing and broadcast routing. Independent of the system size, every node in the network has a fixed size; therefore, it is used intensively in large-sized systems. In this paper, we examine a reliable omega-based multiprocessor system that preserves its full rigid omega configuration even in th...

Data were analyzed from the U.S. Health Examination Survey (Cycle II) to determine relationships between blood pressure and other characteristics. This survey examined a national probability sample of children aged 6-11 years. Significant relationships were found for blood pressure and the following variables: chronological and skeletal age, skinfold thickness (adiposity) and other anthropometr...
