Electrical Discharge Machining (EDM) is the process of machining electrically conductive materials by using precisely controlled sparks that occur between an electrode and the work piece in the presence of a dielectric fluid. Aluminium Metal Matrix Composites (AMMC’s) are new generation engineering materials that possess superior physical and mechanical properties compared to non-reinforced all...

Electrical Discharge Machine (EDM) is one of the non-traditional machining processes. EDM process is based on thermoelectric energy between the work and an electrode. A pulse discharge occurs in a small gap between the work piece and the electrode and removes the unwanted material from the parent metal through melting and vaporization. The electrode and the work piece must have an electrical co...

Titanium surfaces processed by wire-type electric discharge machining (EDM) are microfabricated surfaces with an irregular morphology, and they exhibited excellent in vitro bone biocompatibility. In this study, the efficiency of in vivo osteogenesis on EDM surfaces was investigated by surgically placing screw-shaped EDM-processed and machined-surface implants into the femurs of four Japanese wh...

the micro wire electrical discharge machining (micro wire-edm) process is a modern machining process with various applications in manufacturing micro-parts. the recast layer remaining on the machined surfaces is an inevitable complication of this process. this layer can subsequently affect the machined parts performance. to optimize the recast layer in the micro wire-edm of the molybdenum micro...

If A is a real symmetric matrix and P is an orthogonal projection onto a hyperplane, then we derive a formula for the Moore-Penrose inverse of PAP . As an application, we obtain a formula for the MoorePenrose inverse of a Euclidean distance matrix (EDM) which generalizes formulae for the inverse of a EDM in the literature. To an invertible spherical EDM, we associate a Laplacian matrix (which w...

microhole electrical discharge machining (EDM) system with daptive fuzzy logic control and precision piezoelectric stage is eveloped in this study. A high-speed EDM monitoring system is mplemented to measure the gap voltage, current, and ignition elay time, which are used to derive three input parameters—the verage gap voltage, deviation in spark ratio, and change in the eviation in spark ratio...

In the context of the minimal supersymmetric seesaw model, the CP-violating neutrino Yukawa couplings might induce an electron EDM. The same interactions may also be responsible for the generation of the observed baryon asymmetry of the Universe via leptogenesis. We identify in a model-independent way those patterns within the seesaw models which predict an electron EDM at a level probed by pla...

The search for electric dipole moment (EDM) using ultra cold neutrons (UCNs) may discover new Physics beyond the Standard Model (SM) of electroweak interaction, where the presence of EDM, which would signal T violation and thus CP violation (by assuming CPT invariance), may explain the asymmetry of particle-antiparticle observed in our universe. In the measurement of EDM, a small, uniform and f...

We discuss the sensitivity of the high-scale supersymmetry (SUSY) at 10–1000 TeV in B, Bs, K and D meson systems together with the neutron electric dipole moment (EDM) and the mercury EDM. In order to estimate the contribution of the squark flavor mixing to these flavor changing neutral currents (FCNCs), we calculate the squark mass spectrum, which is consistent with the recent Higgs discovery....

Image quality assessment (IQA) methods play important roles in many applications such as image communication, reception, compression, restoration, and display. No-reference IQA metrics are required to resolve an image when there is a lack of a reference image that is required for fullreference IQA metrics. We propose a no-reference IQA method to evaluate the image quality by using the differenc...
