In this paper we investigate the problem of simultaneously allocating orders and mobile storage racks to static pickers. Here are allocated pickers enable them pick all products for that have been them. Problems type considered here arise in facilities operating as robotic fulfilment systems. We present a formulation an integer program discuss complexity problem. two heuristics (matheuristics) ...

PROBLEM AND METHOD This paper takes a critical look at the present state of bicycle infrastructure treatment safety research, highlighting data needs. Safety literature relating to 22 bicycle treatments is examined, including findings, study methodologies, and data sources used in the studies. Some preliminary conclusions related to research efficacy are drawn from the available data and findin...

Receptor for activated C kinase (Rack)-1 is a protein kinase C-interacting protein, and contains a WD repeat but has no enzymatic activity. In addition to protein kinase C, Rack-1 also binds to Src, phospholipase Cgamma, and ras-GTPase-activating proteins. Thus, Rack-1 is thought to function as a scaffold protein that recruits specific signaling elements. In a cytokine signaling cascade, Rack-1...

The rack is increasingly replacing individual servers as the basic building block of modern data centers. Future rack-scale computers will comprise a large number of tightly integrated systems-on-chip, interconnected by a switch-less internal fabric. This design enables thousands of cores per rack and provides high bandwidth for rack-scale applications. Most of the benefits promised by these ne...

Erasure coding is widely used for massive storage in data centers to achieve high fault tolerance and low storage redundancy. Since the cross-rack communication cost is often high, it is critical to design erasure codes that minimize the cross-rack repair bandwidth during failure repair. In this paper, we analyze the optimal trade-off between storage redundancy and cross-rack repair bandwidth s...

This paper deals with the optimization analysis of Steering Rack. Steering Rack Bending CAE analysis technology is indispensable for developing and mass-producing the Steering Gear assembly. By using Finite Element method, a stress analysis has been carried out. Steering Rack Deflection and Bending stresses are found. Various CAE iterations shows rack weight reduction by keeping Stress constant...
