In this paper, the transient refrigerant gas flow in a two-cylinder rolling piston type rotary compressor is simulated using STAR-CD, a general computational fluid dynamics (CFD) software. Three models with different suction piping systems are calculated respectively, one is two suction pipes were connected from accumulator to each cylinder separately (separate suction piping system), the other...

Location aware computing is popularized and location information has more important before. Ubiquitous computing also needs locaiton information. In this paper we propose location estimation system using multi-hop wireless ad-hoc network. The proposed system estimates locations of mobile hosts, using distance between hosts and the locations of some special hosts which know each location by GPS ...

This paper describes a Bayesian scheme for incrementing the Hough Transform (HT) accumulator to improve the performance of the HT, making it more robust to noise. The proposed technique analytically computes the uncertainty of each feature point based on its gradient and location in the image. Using the estimated uncertainty of each feature point, a Bayesian probabilistic scheme is proposed to ...

The proposed paper consisting the design and implementation of the 64 bit MAC (Multiply Accumulate Unit) for large number of arithmetic operations. The proposed design has multiplier and accumulator units, multiplier block perform normal multiplication operation. The proposed multiplication can be designed by using Wallace tree algorithm. And accumulator it performs two operations; one is stori...

The Standard Hough Transform (SHT) is used to find lines, circles and other image features in edge maps containing edge points. Edge points which potentially can ‘vote’ for a given line (called its ‘line support’) are highly dependent of line position and orientation due to the boundedness of images. If accumulator array peaks are used to find lines then peripherally located lines are missed. U...

The article presents an improved scheme and pilot-industrial copy of a flat reflector solar air heating collector with heat accumulator. balance equation the accumulator is constructed, its energy efficiency based on it. Considering local climatic meteorological characteristics city Karshi, useful performance coefficient was determined experiment conducted This designed device proposed as activ...

In this paper we show that an accumulator can be modified to behave as a Non-Linear Feedback Shft Register suitable for test response compaction. The hardware required for this modification is less than that required to mod& a register to a Multiple Input Linear Feedback Shgt Register, MISR. We show with experiments on ISCAS’85, ISCAS’89 benchmark circuits and various types of multipliers that ...

Basic: linear inequalities containing only current accumulator values (i.e. ci≥0) History Variables: number of previous accumulator values (i.e. ci-2+1≥ci) State Variable: include a variable q representing the current state (i.e. ci-ci-1≤q) State Specific Implied Constraints: generate ICs that hold at specific states (i.e. q=s ⇒ ci=ci-1) Index Variable: include the current index (i.e. 2ci≤i) Ex...

Abstract A laboratory experiment was carried out at the College of Agriculture, University Anbar, located 43°20‘09.7“E longitude, 33°25‘36.7“N latitude for period from 1/10/2021 to 1/10/2022, study effect date residues, organic acids, and wetting / drying cycles on some physical properties gypsiferous soil. The soil selected site Fallujah palm station that longitude 43º51'. 05. 36 E. 33º17'. 46...
