introduction: the aim of this in vitro study was to evaluate the effect(s) of three canal lubricants i.e. sodium hypochlorite, rc-prep as the paste form of ethylenediaminetetraacetic acid (edta) and aqueous edta, on the occurrence/incidence of fracture, deformity and metal slivering of protaper rotary instruments. methods: a total of 120 mesial canals ( i.e. mesiobuccal and mesiolingual) of fir...

A company’s ability to flexibly adapt to changing business requirements is one key factor to remain competitive. The required flexibility in peopledriven processes is usually achieved through ad-hoc workflows. E ective guidance in ad-hoc workflows requires simultaneous consideration of multiple goals: support of individual work habits, exploration of crowd process knowledge, and automatic adapt...

We present the CBTree, a new counting-based self-adjusting binary search tree that, like splay trees, moves more frequently accessed nodes closer to the root. After m operations on n items, c of which access some item v, an operation on v traverses a path of length O(log m c ) while performing few if any rotations. In contrast to the traditional self-adjusting splay tree in which each accessed ...

Splay and randomized search trees (RSTs) are self-balancing binary tree structures with little or no space overhead compared to a standard binary search tree (BST). Both trees are intended for use in applications where node accesses are skewed, for example in gathering the distinct words in a large text collection for index construction. We investigate the efficiency of these trees for such voc...

A simple concept for automatic adjustment of important VLSI{circuit properties was proposed in 1]. As an application, a self adjusting monooop is reviewed, and detailed measurements are discussed regarding a possible implementation in the LHC 1 readout chip for the ATLAS{experiment 2].

Distributed Systems are useful for computation and storage of large scale data at dispersed location. Distributed File System (DFS) is a subsystem of Distributed System. DFS is a means of sharing of storage space and data. Servers, Storage devices and Clients are on dispersed location in DFS. Fault tolerance and Scalability are two main features of distributed file system. Performance of DFS is...

We propose and analyze a self-adjusting Quality of Service (QoS) control scheme with the goal of optimizing the system reward as a result of servicing different priority clients with varying workload, QoS and reward/penalty requirements. Our scheme is based on resource partitioning and designated “degrade QoS areas” such that system resources are partitioned into priority areas each of which is...

The scroll compressor incorporates new construction concepts and is quite different from other types of compressor. This unique and simple compression mechanism has a number of advantages such as small size, light weight, high efficiency, long life, and quiet operation. The compliant mechanism is one of the key ways to improve the performance and reliability of scroll compressors. The concept o...

By using tools from synthetic biology, sophisticated genetic devices can be assembled to reprogram mammalian cell activities. Here, we demonstrate that a self-adjusting synthetic gene circuit can be designed to sense and reverse the insulin-resistance syndrome in different mouse models. By functionally rewiring the mitogen-activated protein kinase (MAPK) signalling pathway to produce MAPK-media...
