Based on metamaterials and transformation optics theory, we develops a method to design 3D invisibility cloak with arbitrary shapes. The proposed electromagnetic invisibility cloak can perfectly hide the target object with arbitrary shapes and materials. Full-wave simulation results demonstrate that 3D electromagnetic invisibility cloaks designed by the proposed method have good performance for hiding...
Quasiconformal maps have been utilized for generating transformation optical devices with a range of applications including invisibility cloaks, waveguide benders, couplers, surface-conformal lenses and antennas. Here, we discuss their generation by numerically solving the Poisson's equation where the analytic solution of a typical electrostatic problem in the virtual space acts as a seed in numerically...
A swing-arm conditioning is generally adopted for chemical mechanical polishing (CMP) system to recover the surface roughness of polishing pad. However, the conditioning process results in uneven pad profile. During conditioning, locally excessive pad wear relates to the pad lifetime in CMP process. In this paper we investigate on the relationship of locally controlled swing condition and maximum...
This paper reports on the urban installation SoundscapesLandscapes (SSLS), an enhanced sound walk guided by a custom mobile application. It explores the aesthetic motivations of the artists involved before examining the manner in which these motivations shape the rationale and design of the project. Creative issues are approached from a musical perspective, and the focus of the paper is to place the...
A generalized cavity method is presented for accurate characterization of powdered material. Polymer nanocomposites Cu/PEO, SS/PEO and Fe/PEO are synthesized and processed for the preparation of lightweight, cost effective microwave absorbing materials. The variation of dielectric constant and the loss factor are observed with addition of metal particles in the base matrix. The complex permittivity...
A flexible fiber conditioner was developed as a surface reference conditioning tool in CMP (Chemical Mechanical Planarization) process. The conditioner keeps contact force of each fiber edge constant to the pad by making use of fiber bending effect. In this paper, the running test was evaluated using the flexible fiber conditioner. The result indicated that the fiber conditioner achieved long life...
This paper describes the advancements on the Metaplastic Arts and Design research field through its own cyber media and interdisciplinary methodologies. It enhances the metaplastic discipline within art and sciences application fields. In the conclusion of this paper some examples of applications are introduced.
Oil spill detection becomes very important nowadays, due to the importance of oil and to prevent pollution caused by oil leakage. Synthetic Aperture Radar (SAR) images show oil spill boundaries clearly. An oil spill appears as an obscure spot in SAR images. Therefore, thresholding is considered the best method to extract this patch and define its boundaries clearly. This paper proposes a novel thresholding...
Audio-Games (AGs) are electronic games that mainly (or exclusively) implement auditory means to express the game's plot, mechanics and content. AG players need to concentrate on perceiving sound, in order to understand and play the game. Recent developments in the field of edutainment suggest that AGs can be implemented not only as entertaining systems, but also as valid tools for research and education...
Titania (TiO2) has been an important renewable material that is able to convert solar energy into chemical energy in recent years. Therefore, the main focus of this paper centers around different strategies and precursors to prepare TiO2 with various shapes, e.g. perforated hollow TiO2, anatase hollow TiO2 spheres, well-aligned TiO2 and rambutan-like TiO2/liquid crystal composite, so as to utilize...
the paper reported about new practical system for 3D three dimensional (3D) nano-manipulation. The system consists of advanced high precision nano-manipulators based on piezoelectric resonance motors and end-effectors. The end-effector is the bimetallic composite nanotweezers based on Ti2NiCu alloy with shape memory effect. This nano-tweezer is easy in use micron-size nano-tool controlled by semiconductor...
Observation and evaluation of damage growth on contact surfaces caused by arc discharges are important for realizing better understandings of contact phenomena. For that purposes, an experimental system enabling observation and evaluation of growth processes of a crater or a pip (damage shapes) during switching operations has been constructed. Up to now, evaluation of a movable cathode surface profile...
The Copper-Chromium (CuCr) contact material is the most widely used material for the contacts of the vacuum interrupters (VI). Performance of the VI is greatly influenced by the properties of contact materials. During switching operations, such as short-circuit current interruption, a vacuum arc is generated which in turn produces melted and resolidified layers at the contact surface. Melting followed...
Vibration attenuation by means of tuned mass dampers is a common practice in engineering since many years. Usually, their dynamic features are chosen so that a tuning on the modal characteristics of the system to control is achieved. Although such components can be very effective in reducing vibrations, they suffer of some drawbacks. The main one is that they cannot change their dynamic features in...
The electronics packaging in microsystems technology for medical applications includes various tasks. The interdisciplinary approach is the most important basis for the success of a product. For the reliable operation of medical microsystems different factors must be considered. The functionalization of a catheter depends on different influence factors. The form factor takes the most important role...
A keyword-based query is not sufficient for retrieving presentations. We assume that episodic memories about authoring slides and giving a presentation can be used for query because users easily recall and recognize slides associated with such memories. In this study, we present slide retrieval based on research episode networks that are a network composed of slides, episodic information and the links...
Pollen tube growth is an essential part of the sexual reproductive process in plants. It is the result of a complex interaction of cytoplasmic contents (proteins, ions, cellular structures, etc.). Existing pollen tube models use differential equations to represent these complex intra-cellular interactions that lead to growth. As a result of this complex nature, these models are not used to verify...
3D Printing or Additive Manufacturing (AM), refers to a new class of technologies of making products directly from any three-dimensional digital models. Broader applications of AM require to lower the cost of AM machines. However, products fabricated by low-end machines suffer from the issue of low dimensional accuracy. In this paper, we intend to address this issue for Fused Deposition Modeling (FDM)...
Comfort, appearance and price are important factors for users when purchasing a pair of new shoes. And shoes comfort is more and more emphasized with the improvement of people's quality of life. But there do not exist any standards for shoes comfort. In this paper, a fuzzy comprehensive evaluation model is studied based on the evaluation index system of shoes comfort. The result shows that the fuzzy...
