  • DWTs are constantly used to solve and treat more and more advanced problems. The DWT algorithms were initially based on the compactly supported conjugate quadrature filters (CQFs). However, a drawback in CQFs is due to the nonlinear phase effects such as spatial dislocations in multi-scale analysis. This is avoided in biorthogonal discrete wavelet transform (BDWT) algorithms, where the scaling and wavelet filters are symmetric and linear phase. The biorthogonal filters are usually constructed by a ladder-type network called lifting scheme.

  • Electrochemistry has been undergoing significant transformations in the last few decades. It is now the province of academics interested only in measuring thermodynamic properties of solutions and of industrialists using electrolysis or manufacturing batteries, with a huge gap between them. It has become clear that these, apparently distinct subjects, alongside others, have a common ground and that they have grown towards each other, particularly as a result of research into the rates of electrochemical processes....

  • The study conducted by Hiller et al. (2011) to investigate the concentrations, distributions, and hazards of polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs). PCBs are used mainly as coolant and electronic industries (capacitors, transformers), paints, sealants for wood, cutting and lubricating fluids, plasticizers, and as dielectric fluids. Therefore, at the former site of PCB manufacturing area in Slovakia, high concentrations of PCBs are detected in soils, sediments, humans, and wildlife (Kocan et al., 2001; Petrik et al., 2001; Hiller et al., 2011)....

  • Introduction: Electrocrystallization refers to nucleation and crystal growth occurring on electrodes in electrochemical systems under the influence of an electric field. Nucleation and growth phenomena are involved in many battery systems, where the electron transfer is coupled to various phase transformations occurring during charge and/or discharge in the active electrode materials. For example, in the lead–acid battery the electrochemical reactions involve formation of different electronically conducting and insulating crystal phases (e.g.

  • The Government in May 2011 approved the Medium Term Plan (MTP), which is expected to drive economic growth over the next five years, 2011-15. The Plan will guide the formulation of National Budgets and other social-economic policies of the State. The MTP requires US$9 billion to be implemented over the period 2011-15 and funding is expected from the domestic and external sources including reliance on Public Private Partnership (PPP).

  • The macroeconomic configuration at the present time is conducive to sizeable interest rate exposures in the financial industry. Because virtually all firms are tempted to take the same risks (“herding”), there is also a very important systemic dimension. All firms will not be able to get out when expectations of future rates change – leading to “overshooting” in market interest rates or even illiquidity in interest rate hedging markets.

  • Thecaa3-oxidase from Thermus thermophilushas been studied with a combined electrochemical, UV/VIS and Fourier-transform infrared (FT-IR) spectroscopic approach. In this oxidase the electron donor, cytochromec, is covalently bound to subunit II of the cytochrome c oxidase. Oxidative electrochemical redox titrations in the visible spectral range yielded a midpoint potential of )0.01 ± 0.01 V (vs. Ag/AgCl/3MKCl, 0.218 V vs. SHE¢) for the hemec.

  • These days, it is impossible to think of an area of knowledge that can keep on developing without a collaboration in interdisciplinary fields. Electromotive force is a type of energy per unit of electric charge that is converted reversibly from chemical, mechanical, or other forms of energy into electrical energy by a dynamo, battery, electrochemical cells, thermoelectric devices, solar cells, transformers, and so on. The theory of electromotive Force is currently one of the most important research topics within the electrical engineering domain.

  • This volume, of a two volume set on ionic liquids, focuses on the applications of ionic liquids in a growing range of areas. Throughout the 1990s, it seemed that most of the attention in the area of ionic liquids applications was directed toward their use as solvents for organic and transition-metal-catalyzed reactions. Certainly, this interest continues on to the present date, but the most innovative uses of ionic liquids span a much more diverse field than just synthesis.
