A directional morphological operation can be performed by utilizing a rotational structuring element with a directional information, and its associated processing methods for overlapping and enclosing are proposed. As an example of overlapping method derived from the directional morphological operation, a distribution of high/low atmospheric pressures is obtained from the wind direction of weat...

ZTA powder with a composition of 85 wt% alumina/15 wt% zirconia was prepared by a gel precipitation method. Sinter forging was performed with this powder to enhance the mechanical properties of ZTA materials. The influence of processing flaws on mechanical properties of sinter forged materials and pressureless sintered materials was investigated. Sinter forging at 40 MPa effectively decreases p...

In order to help the forging enterprise realize energy conservation and emission reduction, the scheduling problem of furnace heating was improved in this paper. Aiming at the charging problem of continuous heating furnace, a multi-objective furnace charging model with minimum capacity difference and waiting time was established in this paper. An improved strength Pareto evolutionary algorithm ...

In warm and hot forging, the dies are subjected to high contact pressures and temperatures. The selection of the die material, hardness and coating is critical for increasing die life. Recent studies indicate that ceramic dies and various surface treatment techniques represent, in certain applications, cost effective techniques for improving die life. This paper reviews the state of technology ...

Detecting objects and estimating their 6D poses is essential for automated systems to interact safely with the environment. Most pose estimators, however, rely on a single camera frame suffer from occlusions ambiguities due object symmetries. We overcome this issue by presenting novel symmetry-aware multi-view estimator called SyMFM6D. Our approach efficiently fuses RGB-D frames multiple perspe...

The most common parallelization strategy for many Computational Mechanics (typified by Computational Fluid Dynamics(CFD) applications) which use structured grids, involves the one directional partition based upon slads of grids. For parallelised versions of CFD codes to scale well we must employ two (or more) dimensional partitions. However, FORTRAN code implementations by multi-directional par...

This chapter introduces the concept of multi-beam antenna (MBA) in mobile ad hoc networks and the recent advances in the research relevant to this topic. MBAs have been proposed to achieve concurrent communications with multiple neighboring nodes while they inherit the advantages of directional antennas, such as the high directivity and antenna gain. MBAs can be implemented in the forms of mult...

OF THE DISSERTATION Cross-Layer Design for Wireless Networks Using Antenna Arrays by Ece Gelal Doctor of Philosophy, Graduate Program in Computer Science University of California, Riverside, August 2009 Professor Srikanth V. Krishnamurthy, Chairperson One of the major problems experienced by wireless multi-hop networks is the intermittent network connectivity, which is a consequence of fluctuat...

While genetically inspired approaches to multi-objective optimization have many advantages over conventional approaches, they do not explicitly exploit directional/gradient information. This paper describes how steepestdescent, multi-objective optimization theory can be combined with EC concepts to produce improved algorithms. It shows how approximate directional information can be efficiently ...
