Finding a match between partially available deformable shapes is a challenging problem with numerous applications. The problem is usually approached by computing local descriptors on a pair of shapes and then establishing a point-wise correspondence between the two. In this paper, we introduce an alternative correspondence-less approach to matching fragments to an entire shape undergoing a non-...

We present a loop property generation method for loops iterating over multi-dimensional arrays. When used on matrices, our method is able to infer their shapes (also called types), such as upper-triangular, diagonal, etc. To generate loop properties, we first transform a nested loop iterating over a multidimensional array into an equivalent collection of unnested loops. Then, we infer quantifie...

The increasing complexity and size in cruise ships demands for lightweight structures practical but accurate design methods. Conventionally, the focus has been on steel parts of ship, as they make most its weight. However, proportions other materials are increasing. Therefore, this study attempts to provide better understanding how one could reach designs insulating glass units (IGUs) ships. Th...

This paper focuses on Piano Key Weirs (PKWs) as an effective solution for improving the discharge capacity of spillway systems. The flow behavior in inlet and outlet keys is experimentally studied to analyze PKWs with different plan shapes (i.e., rectangular, trapezoidal, triangular). results show that keys, aeration regimes extend higher values headwater ratios (Ho/P) by increasing length magn...

A new approach for constructing deformable continuous medial models for anatomical structures is presented. Medial models describe geometrical objects by first specifying the skeleton of the object and then deriving the boundary surface corresponding to the skeleton. However, an arbitrary specification of a skeleton will not be "valid" unless a certain set of sufficient conditions is satisfied....

Abstract Solar stills utilization has received great interest in arid isolated regions. In this study, experimental approaches have been investigated to prove the impact of corrugated absorber shape on hemispherical solar still performance. Four geometric shapes including present flat, triangular, semi-circular, square forms were tested for absorber. Five distillers fabricated and tested. The f...

Abstract This paper deals with the analysis of fluid flow around bluff bodies using computational dynamics. Two-dimensional rectangular body, semi-circular tip, triangular tip and elliptical nose cone shapes have been considered in paper. The are analysed at various Mach numbers, ranging from 1.5 to 10. aerodynamic characteristics like Drag coefficient drag force investigated. Also, formation s...

Recent X-ray observations of microquasars and Seyfert galaxies reveal the broad emission lines in their spectra, which can arise in the innermost parts of accretion disks. A theoretical analysis of observations and their interpretations were discussed in a number of papers. We consider a radiating annulus model to simulate spectral line shapes. That is a natural approximation for narrow emittin...
