A grid unfolding without refinement method for a new sub-class of polycubes, called Manhattan Towers with H-convex base, is proposed. Such polycubes can be seen both as Tower and an orthostack. direct extension this algorithm to Up-and-Down Orthoterrains also presented.

in this investigation, the performance of a tower for absorption of sulphur dioxide gas into calcium carbonate solution has been studied. the trays had no downcomer and the tower itself was a scaled down pilot from industrial equipment. the industrial scale tower was used for clean up of 110000 m3/hr gas using 40 m3/hr alkaline solution. the study was composed of two parts. in the first section...

This contribution proposes a Mixed Integer Non Linear Programming (MINLP) formulation for optimal design of a catalytic distillation column based on a generic nonequilibrium model (NEQ). The solution strategy for the global optimization combines Simulated Annealing (SA) and Sequential Quadratic Programming (SQP) in order to minimize the objective function. The solution of this MINLP problem yie...

Tibial anatomical landmarks for transverse plane rotation of the tibial tray have not been validated. The current authors propose aligning the tibial tray with both the anterior tibial center point of rotation (ATCPR) and the femoral trochlear groove (FTG) to establish the ideal tibial tray rotation in total knee arthroplasty (TKA). When the tibial tray centerline was aligned with ATCPR and FTG...

Aseptic loosening of the tibial component is the major complication of total knee arthroplasty. There is an association between early excessive shear micromotion between the bone and the tray of the tibial component and late aseptic loosening. Using non-linear finite element analysis, whether a tibial tray with a circumferentially flanged rim and a mating cut in the proximal tibia could minimiz...

The leaning tower illusion is a perceptual illusion in which two identical images of a tower photographed from below appear to diverge when juxtaposed. We manipulated the perceived obliqueness of the (upright) St Mark bell tower in Venice by modifying two parameters both related to the position of the camera with respect to the tower: (a) increasing the peripherality of the tower and (b) reduci...

I conducted a series of laboratory experiments to quantify the effects and elucidate the mechanisms by which Pseudacteon tricuspis Borgmeier phorid ßies affect the exploitative and interference components of interspeciÞc competition in host Solenopsis invicta Buren ants. In manipulative experiments, workers retrieved 50% less food in a foraging tray with phorids present, compared with an equidi...

Floating-roof tanks are widely used in chemical parks and case of fires, it is common to form pool fires with varying ullage height. This paper aimed at examining experimentally analytically the effects height on burning flame behaviors heptane fires. A series fire tests four fuel tray sizes (D = 20–35 cm) five heights (h 3 cm, 5 D/2, D, 2D) was conducted. The characteristics (length position) ...

The Transformer-based encoder-decoder architecture has recently made significant advances in recognizing handwritten mathematical expressions. However, the transformer model still suffers from lack of coverage problem, making its expression recognition rate (ExpRate) inferior to RNN counterpart. Coverage information, which records alignment information past steps, proven effective models. In th...
