Three fast mutual exclusion algorithms using read-modify-write and atomic read/write registers are presented in a sequence, with an improvement from one to the next. The last algorithm is shown to be optimal in minimizing the number of remote memory accesses required in a resource busy period. Remote memory access is the key factor of memory access bottleneck in large shared-memory multiprocess...

Efficient detection of pavement cracks can effectively prevent traffic accidents and reduce road maintenance costs. In this paper, an improved YOLOv5 network combined with a Bottleneck Transformer is proposed for crack detection, called YOLOv5-CBoT. By combining the CNN Transformer, YOLOv5-CBoT better capture long-range dependencies to obtain more global information, so as adapt long-span task ...

Zusammenfassung Im Jahr 2019 haben deutsche Universitäten das Jubiläum einer 50-jährigen Informatikausbildung gefeiert. Die TU Dresden blickt dabei seit 1969 als erste Universität auf Erfahrungen in beiden deutschen Staaten zurück. Während die historische Entwicklung der für BRD gut dokumentiert ist, besteht Dokumentation durch Informatik Spektrum DDR eine Lücke. befand sich ihren Anfängen Auge...

During designing a business process model, to predict its performance is very important. The performance of business operational process is heavily influenced by its bottlenecks. In order to improve the performance, finding the bottlenecks is critical. This paper proposes a theoretical analysis method for bottleneck detection. An abstract computational model is designed to capture the main elem...

Knowing the bottleneck is one of the keys to improving a production system. The active period method is one approach to detect shifting bottlenecks that most other bottleneck detection methods have problems with. Yet, like many other methods, these detections are limited to detecting the past and present bottlenecks. In this paper, we combined the active period method with the buffer Preprint o...
