We have shown, how a schedulability analysis, including a codesign approach for periodic tasks, can be extended for the analysis of sporadic tasks and dependencies between tasks, what often occurs in SDL/MSC specified systems. To allow this we extended the classical task model with starting points for each task. To calculate the response times of sporadic tasks we consider instances of tasks. T...

Let P be a simple polygon of n vertices and let S be a set of n points called sites lying in the interior of P. The geodesic-distance between two sites x and y in P is defined as the length of the shortest polygonal path connecting x and y constrained to lie in P. It is a useful notion in graphics problems concerning visibility between objects, computer vision problems concerned with the descri...

The SCl’s method of obtaining comprehensive coverage of the literature has its foundation in Bradford’s Law (16.17). In general, this law states that a small percentage of journals account for a large percentage of the signiEcant articles in any given field of science. In support of this, a study of Physics Abstracts by Keenan and Atherton (18) shows that 50% of the items abstracted are taken f...

Primary Care and Advanced Access For most patients, their primary care physician is their major access point into the health care system. Yet primary care practices often have long waits for appointments and may have difficulty in accommodating patients who have potentially urgent problems. As a result, patients experience delays in treatment and may be seen by someone other than their own phys...

An important element of the cost of distance is time taken in delivering final and intermediate goods. We argue that time costs are qualitatively different from direct monetary costs such as freight charges. The difference arises because of uncertainty. Unsynchronised deliveries can disrupt production, and delivery time can force producers to order components before demand and cost uncertaintie...

The development of marine insurance has been imperative for the expansion of longdistance maritime trade. Without marine insurance, the Dutch Republic would not have been able to enlarge its trade networks and in all likelihood would not have prospered as it did in the early modern era. The emergence and early development of marine insurance in the Netherlands has been fairly well documented. T...

This paper presents a new hardware-software co-design methodology for resource constrained SoC realized in a deep submicron process (DSM). The methodology is useful for multimedia applications optimized for latency. The approach addresses layout and hardware aspects relevant to system design: it considers the dependency of task communication speed on interconnect parasitic, as well as the possi...

were made for get_file operations on a disk to memory basis, i.e. the files were requested from the file servers disk and discarded on the receivers side. Thus we where able to neglect the influence of local disk write operations upon the results. This resembles a scenario where a user requests a certain file (e.g. a drawing) for viewing. Since drawings are typically stored as bitmaps (binary) ...
