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...

Objective. The aim of this study was to (a) determine the rate of redundant publication in the pediatrics literature and (b) to characterize these articles. Methods. Index articles in JAMA Pediatrics, Pediatrics, and the Journal of Pediatrics from 2010 were identified using PubMed. Possible redundant material from 2008 to 2012 were searched using the authors' names. Suspected duplicates were ca...

BACKGROUND Bone fragility is increased in patients with type 2 diabetes mellitus (T2DM), but a useful method to estimate bone fragility in T2DM patients is lacking because bone mineral density alone is not sufficient to assess the risk of fracture. This study investigated the association between prevalent vertebral fractures (VFs) and the vertebral strength index estimated by the quantitative c...

In this paper, three rock types including Sandstone, Mudstone, and Crystalline Gypsum were part of a laboratory study conducted to develop a dataset for predicting the unconfined compressive strength of UAE intact sedimentary rock specimens. Four hundred nineteen rock samples from various areas along the coastal region of the UAE were collected and tested for the development of this dataset and...

In this article, the dynamic stability of a mobile manipulator using ZMP compensation is considered. A unified approach for the two subsystem is formulated using redundant scheme. First, to conserve the dynamic stability of the system, we define the performance index for the redundant system using ZMP(Zero Moment Point). This performance index represents the stability of the whole mobile manipu...

This paper presents a tunable index compression scheme for supporting time-travel phrase queries over large versioned corpora such as web archives. Support for phrase queries makes maintenance of word positions necessary, thus increasing the index size significantly. We propose to fuse the word positions in many neighboring versions of a document, and thus exploit the typically high level of re...

OBJECTIVES To investigate the link between cigarette smoking and muscle strength in Japanese men. METHODS We used data on 4249 Japanese men, aged 43.3±13.9 years, in this cross-sectional investigation study. Grip strength and leg strength were measured as indicators of overall muscle strength. Meanwhile, subjects' cigarette smoking habits were recorded by trained medical staff. The effect of ...
