Heat Affected Zone (HAZ) is the area on a weldment mostly affected by intensity of applied heat without melting. This deteriorates faster due to microstructural changes that occur during welding operations. Weld structural failures can be catastrophic and unpredictable at times. When there no loss human life involved, damages as result weld failure usually takes more time cost repair/replace. F...

This paper addresses the problem of aerial image matching. We analyze existing approaches to this problem and show that, though the modern algorithms cope with the task quite well, their results are deteriorated in case of low overlap and significant rotation angle between the images. A two-stage feature-based image matching scheme is presented. It is shown that preliminary stage of simplified ...

In cellular systems there normally exists an overlap cell coverage area (area covered by two or more base stations) which has valuable practical applications: soft handoff is an important feature of CDMA systems and in hard handoff the overlap area permits the handover request queuing as a handover prioritisation scheme. While an extensive research effort has been done to model the terminal res...

1. In undissected, freely mobile earthworms the sensory input for tactile stimulation to the MGF and LGF shows a region of overlap occupying a number of segments behind the clitellum. The average number of overlapping segments from a sample of 14 worms was 13 (range 0-28). 2. The overlap zone consists of segments from which both LGF and MGF spikes can be elicited. 3. Increasing stimulus intensi...

Abstract Hydraulic fracturing is a popular method used in the petroleum industry to increase well performance by improving permeability of reservoir. However, while there has been extensive research on development length fracture, fractured height frequently assumed be equal reservoir thickness. The objective this paper study influence formation rock characteristics and impact underground stres...
