We propose a method to detect circular arcs, including the determinations of their centers, radii, lengths, and midpoints. The center, radius of a circular arc can easily be determined using circular Hough transform. But, the determinations of the arc midpoint and length are more complicated. Theoretical analysis of the centroid of the near peak Hough transform data is presented. Then, the arc ...

The estimation of the statistics of buffer overflows in networks of queues is inherently costly, simply because of the rarity of these events. This paper presents two eztensions to the known theory for finding optimal transformations for simulating such networks. The first is a direct proof of the asymptotic (as buffer size becomes large) optimality of ezchanging the arrival and service rates i...

Abstract Invar alloys are used for high‐precision applications due to their invariance of the coefficient thermal expansion over a temperature range up about 250 °C. The present study determines mechanical and corrosive properties 36 (64 % Iron – Nickel) specimens produced by laser powder bed fusion. Tensile were fabricated investigate properties. influence horizontal vertical building orientat...

2,3,7,8-tetrachlorodibenzo-p-dioxin (tcdd) is a by-product o f t he trichlorophenol (herbicide) production and is also produced through a variety of combustion processes. it appears that tcdd is a ubiquitous chemical, particularly in industrialised countries, and the liver is the target organ of its toxicity. the prominent hepatotoxic effect of tcdd is progressive centrilobular necrosis. the is...

Modern reorder buffers (ROBs) were conceived to improve processor performance by allowing instruction execution out of the original program order and run ahead of sequential instruction code exploiting existing instruction level parallelism (ILP). The ROB is a functional structure of a processor execution engine that supports speculative execution, physical register recycling, and precise excep...
