Describing the workings of a specially written caching algorithm unofficially called Top40 and comparing it to two more common algorithms LRU (Least Recently Used) and LFU (Least Frequently Used) this report tries to show the effectiveness of Top40 algorithm in a media streaming environment. Simulations where done using real data. These simulations show the effectiveness of the Top40 algorithm ...

The buffer-cache replacement policy of the OS can have a significant impact on the performance of I/Ointensive applications. In this paper, we introduce a simple fingerprinting tool, Dust, which uncovers the replacement policy of the OS. Specifically, we are able to identify how initial access order, recency of access, frequency of access, and long-term history are used to determine which block...

Recent recognition of the markedly high prevalence of temporomandibular joint (TMJ) arthritis in children with juvenile idiopathic arthritis (JIA) coupled with the significant morbidity associated with TMJ damage has prompted increased interest in both the clinical and pathological aspects of TMJ arthritis. This review focuses on the prevalence of TMJ arthritis in JIA, the imaging modalities us...
