Abstract This paper reports the optimal use of control zones to achieve required uniformity temperature distribution in local postweld heat treatment welds 9% Cr heat-resistant large pipe system. In this research, post weld tests on with different were carried out 9%Cr steel pipes (OD 710 mm × 35 and OD 575 mm), which was further used for development thermal analysis model via abaqus. The resea...

The scope of the present paper is the derivation of a merit function which predicts the visual perception of LED spot lights. The color uniformity level Usl is described by a linear regression function of the spatial color distribution in the far field. Hereby, the function is derived from four basic functions. They describe the color uniformity of spot lights through different features. The re...

In Nuclear Magnetic Resonance (NMR) experiments, besides the apparatus designed to acquire the NMR signal, it is necessary to generate a radio frequency electromagnetic field using a device capable to transduce electromagnetic power into a transverse magnetic field. We must generate this transverse homogeneous magnetic field inside the region of interest with minimum power consumption. Many con...

This paper presents a performance-driven I/O pin routing algorithm with special consideration of wire uniformity. First, a topological routing based on min-cost max-flow algorithm is proposed. In this phase, an exponential weight function is used to guide the flow distribution which is very helpful in distributing wires, globally and uniformly, on the whole routing area. Then a physical routing...

The article analyzes factors leading to non-uniformity of water distribution in cooling towers. These include imperfections the design pipelines and nozzles system Previous studies conducted on a model tower-type at Rivne Nuclear Power Plant have revealed uneven nozzles. Simulation simultaneity nozzle activation showed that is activated first has highest flow rate. Therefore, achieve acceptable...
