Abstract. The present paper reports on the influence of process parameters on formation of micro-cracks and recast layer on mild steel during EDM using a copper electrode. Surface quality was evaluated on the basis of work surface roughness, micro cracks and thickness of the recast layer. Current, pulse-on time, pulse-off time and voltage were the

The development of vacant land may be seen from a real options perspective—owners of vacant land have the incentive to delay developing the land and keep their options open (keep the lands undeveloped) if they believe that future development will yield higher value. We investigate whether there is speculative behavior with regard to vacant land d

Digital watermarking is a huge research area which is progressively growing. It covers theoretical studies. novel techniques, attacks and performance analysis. Over the years, the digital watermarking community has focused on developing new techniques for watermark embedding and detection. Analysis of these techniques leads to methods for attacks a

Nowadays, it is easy to obtain, manipulate, distribute and store multimedia contents due to evolution of Internet, excellent multimedia tools and low-cost storage devices. Research community and industry has shown extensive interests in developing and implementing possible solutions via digital watermarking. Digital watermarking is distinctive depe

Internet evolution, along with the advancement of digital multimedia tools have create a major impact in making the storage and distribution of multimedia content a straightforward task. Issues on security have emerged and there is a vital need in protecting the digital content against counterfeiting, piracy and malicious manipulations. This paper

There are quite a number of researches in propOSll1g digital image watermarking using Discrete Wavelet Transform (DWT). However, it is clearly observed that each of them is individually distinctive in terms of its scopes and applications [1][2][3]. The proposed system was thoroughly explained in this chapter. This includes general work flow, propos

Digital watermarking has been inspired from security concerns over multimedia contents due to the advances of computer technology. Nowadays, it is easy to obtain, manipulate, distribute and store these contents due to evolution of Internet, excellent multimedia tools and low-cost storage devices. Research community and industry has shown extensive

An understanding of bus service disparities between urban and rural settlements is necessary to provide the best approach to improving and providing an efficient public transportation system in the country. An efficient public transportation system will contribute towards sustainable economic growth and healthy social development of the district, w

A search for dark matter produced in association with a Higgs boson decaying to a pair of bottom quarks is performed in proton–proton collisions at a center-of-mass energy of 13 TeV collected with the CMS detector at the LHC. The analyzed data sample corresponds to an integrated luminosity of 35.9 fb−1. The signal is characterized by a large mi
