Existing physical model

The aim of the study is to design, analysis and optimization of piston for a single cylinder four stroke over head valve (OHV) spark ignition engine. This paper used reverse engineering techniques, in order to obtain of an existing physical model.

This study corrected and supplemented the broken segments, then use the corrected and supplemented curves to calculate porosity. The porosity calculated in this study for 9 wells has been used by JVPC to build the mining production technology diagrams, whle the existing softwares can not calculate this parameter. The testing result proves that the Artificial Neural Network model (ANN) of this study is great tool for correction and supplementing of the well log curves.

Consolidation of applications in cloud computing environments presents a significant opportunity for energy optimization. As a first step toward enabling energy efficient consolidation, we study the inter-relationships between energy consumption, resource utilization, and performance of consolidated workloads. The study reveals the energy performance trade-offs for consolidation and shows that optimal operating points exist. We model the consolidation problem as a modified bin packing problem and illustrate it with an example.

Annals of Mathematics We study the motion of an incompressible perfect liquid body in vacuum. This can be thought of as a model for the motion of the ocean or a star. The free surface moves with the velocity of the liquid and the pressure vanishes on the free surface. This leads to a free boundary problem for Euler’s equations, where the regularity of the boundary enters to highest order. We prove local existence in Sobolev spaces assuming a “physical condition”, related to the fact that the pressure of a fluid has to be positive. ...

Researches on deductive database systems are not new ones, but propose of data model allowing manipulating data and knowledge on a particular framework is not easy but interesting goal. The paper aims at a model for knowledge in educational and training environment, beside of a presenting the achievement in the existing systems concerning knowledge. Certain data manipulation techniques for knowledge acquisition are proposed in the model, as knowledge discovering techniques in deductive database systems. ...

The minimum number of Cs that can be associated with one A is 1. I know this because the existence of the C to A relationship is mandatory. The maximum number of Cs that can be associated with one A is unlimited (or many). I know this because the cardinality of the C to A relationship is 1-M.
