In this paper we consider the model studied in [17] – a large-scale service system with multiple customer classes and multiple server pools; interarrival and service times are exponentially distributed, and mean service times depend both on the customer class and server pool. It is assumed that the allowed activities (routing choices) form a tree (in the graph with vertices being both customer ...
exposure to vibration is the cause of some occupational injuries and diseases. objective of this study was determination of vibration exposure of tractor drivers and assessment of musculoskeletal disorder . this cross-sectional and descriptive- analytical study was administrated to 95 tractor drivers to census method and measuring induced vibration to the drivers was done in three axis, x, y, a...
The paper presents a global optimization method to compute the minimum limit load factor of trusses under the unknown-but-bounded load uncertainty. We assume that the external forces consist of a part proportional to a load factor and a part that is uncertain around its nominal value. The worst-case limit load factor is introduced as the smallest limit load factor realized with some uncertain p...
A global optimization method is presented for computing the minimum limit load factor of trusses subjected to unknown but bounded loads. We assume that the external forces consist of a part proportional to a load factor and a part that is uncertain around its nominal value. The worst-case limit load factor is introduced as the smallest limit load factor realized with some uncertain parameters. ...
BACKGROUND Viral load (VL) monitoring is the standard of care in developing country settings for detecting HIV treatment failure. Since 2010 the World Health Organization has recommended a phase-in approach to VL monitoring in resource-limited settings. We conducted a systematic review of the accuracy and precision of HIV VL technologies for treatment monitoring. METHODS AND FINDINGS A search...
