We present single and binary black-hole simulations that follow the ‘‘moving-puncture’’ paradigm of simulating black-hole spacetimes without excision, and use ‘‘moving boxes’’ mesh refinement. Focusing on binary black-hole configurations where the simulations cover roughly two orbits, we address five major issues determining the quality of our results: numerical discretization error, finite ext...

Moving car on rough road suddenly gets out of its way for some reason and moves to the edge of the road at the same speed. Since the most important factor in car overturning is vertical acceleration in the wheels and car speed and road conditions determine the vertical instantaneous acceleration, brake system according to change of the spring length is designed in such a way that by monitoring ...

Surabaya locomotive warehouse is one part of the company PT. Kereta Api Indonesia (Persero) as a place to store spare parts for repair and maintenance purposes, especially locomotives. The implementation these inspections repairs, course, requires facilitate process which generally are placed in storage or warehouses. problem that arrangement bin boxes each type group not always fixed so search...

1. Dogs with bilateral auditory cortex lesions were tested on their ability to localize and discriminate brief sounds. In each test the animals were required to approach one of two goal boxes in order to indicate their response. 2. The results showed: a) that the operated animals could not solve the localization tasks when the goal boxes were located more than 125 cm away, but could solve the t...

Transportation and warehouse costs are the two major components of the total logistics cost. To increase the material handling efficiency both in transit and in the warehouse, pallets have been used widely in logistics systems. The manufacturer’s pallet loading problem (MPLP) is to pack identical smaller boxes onto a rectangle pallet to maximize the pallet utilization. In this research, we solv...

This paper gives an overview of a participatory ergonomic intervention aimed at reducing low back pain cases in the dispatch department of a catalogue and e-commerce retail company. Based on the findings of the ergonomic analysis and design committee, the company's own employees redesigned the assembly line's layout. As a result of these changes two job tasks that involved manual material handl...

Anyone who has experience in moving house [the Angewandte team has just done this!] knows that those boxes filled with small books are the heaviest, because these small objects pack so easily. The same entropy effect explains the catalytic selectivity towards the formation of branched hydrocarbons in zeolites. The pink tubes represent the zeolite pores at high loading in which effective size di...

BACKGROUND Hair restoration surgery is one of the most commonly performed cosmetic surgery procedure in men. The main aim of the study was to know the effect of follicular unit extraction (FUE) follicular unit extraction (FUE) on donor area in terms of hair mass/density. METHODS Ten male patients undergoing hair restoration by FUE were included. In each patient, ten boxes of 1 cm2 each were ...
