In this paper, a special class of redundancy optimization problem with fuzzy random variables is presented. In this model, fuzzy random lifetimes are considered as basic parameters and the Er-expected of system lifetime is used as a major type of system performance. Then a redundancy optimization problem is formulated as a binary integer programming model. Furthermore, illustrative numerical ex...

Redundantly actuated parallel kinematic manipulators (RA-PKM) are ideal candidates in robotic applications combining dynamic performance with high accuracy. Actuation redundancy further allows for modulation of the end-effector (EE) stiffness. A recent trend robotics is use inherently compliant and elastic components, eventually leading to soft continuum robots, which shall provide tailored sol...

This paper proposes a method for the optimal placement of phasor measurement units (PMUs) complete observability power system based on degree neighbourhood vertices. A three-stage algorithm is used to determine minimum number PMUs needed make observable. The key objective proposed methodology minimize total completely observe network and thereby installation cost. In addition, technique also fo...

1 Focus and anaphoric destressing Consider a pronunciation of (1) with prominence on the capitalized noun phrases. In terms of a relational notion of prominence, the subject NP she] is prominent within the clause S she beats me], and NP Sue] is prominent within the clause S Sue beats me]. This prosody seems to have the pragmatic function of putting the two clauses into opposition, with prominen...

This paper addresses the mixed integer reliability redundancy allocation problems to determine simultaneous allocation of optimal reliability and redundancy level of components based on three objective goals. System engineering principles suggest that the best design is the design that maximizes the system operational effectiveness and at the same time minimizes the total cost of ownership (TCO...

Reducing latency is a primary concern in computer systems. As cloud computing and resource sharing become more prevalent, the problem of how to reduce latency becomes more challenging because there is a high degree of variability in server speeds. Recent computer systems research has shown that the same job can take 12 times or even 27 times longer to run on one machine than another, due to var...

In many situations involving analysis of experimental data, there exists a degree of redundancy. It is advantageous to identify and reduce the redundant elements of the data in order to reduce the dimensionality of the data, thus enabling better modelling or representation. The subsequent modelling may be performed using linear or nonlinear techniques, whose e ciency may be aided by the preproc...

Background Key to the clinical management of melanoma is the development of new diagnostic tools that predict individual patient prognosis and select from potential treatments those which may be effective. Identifying individual biomarkers in tumour cells to predict susceptibility to apoptotic cell death has thus far been largely unsuccessful, as apoptosis pathways show a high degree of signall...
