Abstract The main defect of additive manufacturing technology based on laser melting is that large thermal deformation easily generated inside the part during forming process. traditional method to adjust process parameters, stress relief annealing and other hardware methods. From point view design, this paper proposed a reduce by changing product structure configuration without form design goa...

The solidification behavior of LuA103 melts in Bridgman geometry is presentedThe contribution of different growth parameters to crystallization of single phase LuA10, are studied. Growth scheme for L U A ~ O ~ N ~ ~ + crystals possessing improved laser properties is described. LuA103 (space group ~:E-~bnm) is the end member of the rhombic rareearth group (LnA103, where Ln = Y or Ln ion between ...

Every internal combustion engine operates on the principle of converting thermal energy into mechanical work. During fuel in cylinders, heat is released. It also has its negative effects; one overheating cylinders and general. Since parts are made metal with own characteristics, optimal temperature must be achieved order to protect components from and, thus, undesirable consequences overheating...

Abstract Children spend a large part of their waking lives in school buildings. There is substantial evidence that poor indoor air quality (IAQ) and thermal discomfort can have detrimental impacts on the performance, wellbeing health schoolchildren staff. Maintaining good IAQ while avoiding overheating classrooms challenging due to unique occupancy patterns heat properties schools. Building sto...

A simple method for balancing the motor driver load across a six-wheeled rover is presented. This method uses the concept of inflammation to model the load on each motor driver by its temperature, decreasing the load as the local temperature increases. The method is compared with both the base case, where all motors run at a fixed load; and a relatively unintelligent method involving shutting o...

The ant colony algorithm is a new technique for combinatorial optimization borrowed from swarm intelligence. This paper outlines an ant colony algorithm to compute the optimal order of restoring sections in a power distribution system. Restoration of distribution feeders after long interruptions creates cold load pickup conditions due to loss of diversity among the loads. The distribution syste...

Structural changes in solid and liquid like clusters and nanoparticles have been investigated by means of molecular dynamics simulations. While in the solid phases of the clusters the reactions leading to structural changes spontaneously occur upon heating, the reverse transition, when decreasing the temperature, is often hindered because of large undercooling effects and missing nucleation sit...

This paper examines the role for tax policies in productivity-shock driven economies with catching-up-with-the-Joneses utility functions. The optimal tax policy is shown to affect the economy countercyclically via procyclical taxes, i.e., “cooling down” the economy with higher taxes when it is “overheating” in booms and “stimulating” the economy with lower taxes in recessions to keep consumptio...
