Abstract:
A fast, yet unconditionally stable, solution of time-domain electric field integral equations (TD EFIE) pertinent to the scattering analysis of uniformly meshed and/or periodic conducting structures is introduced. A one-dimensional discrete fast Fourier transform (FFT)-based algorithm is proffered to expedite the calculation of the recursive spatial convolution products of the Toeplitz–block–Toeplitz retarded interaction matrices in a new marching-without-time-variable scheme. Additional saving owing to the system periodicity is concatenated with the Toeplitz properties due to the uniform discretization in multi-level sense. The total computational cost and storage requirements of the proposed method scale as O(Nt2Nslog Ns) and O(Nt Ns), respectively, as opposed to O(Nt2Ns2) and O(NtNs2) for classical marching-on-in-order methods, where Nt and Ns are the number of temporal and spatial unknowns, respectively. Simulation results for arrays of plate-like and cylindrical scatterers demonstrate the accuracy and efficiency of the technique.

Abstract:
Marching modulus phenomena are often observed in silica-reinforced solution styrene–butadiene rubber/butadiene rubber (S-SBR/BR) tire tread compounds. When such a situation happens, it is difficult to determine the optimum curing time, and as a consequence the physical properties of the rubber vulcanizates may vary. Previous studies have demonstrated that the curing behavior of silica compounds is related to the degree of silanization. For the present work, the effect of silanization temperature and time on the marching modulus of silica-filled rubber was evaluated. The correlations between these mixing parameters and their effect on the factors that have a strong relation with marching modulus intensity (MMI) were investigated: the amount of bound rubber, the filler flocculation rate (FFR), and the filler–polymer coupling rate (CR). The MMI was monitored by measuring the vulcanization rheograms using a rubber process analyzer (RPA) at small (approximately 7%) and large (approximately 42%) strain in order to discriminate the effects of filler–filler and filler–polymer interactions on the marching modulus of silica-filled rubber compounds. The results were interpreted via the correlation between these factors and their effect on the MMI. A higher temperature and a longer silanization time led to a better degree of silanization, in order of decreasing influence.

Abstract:
ABSTRACT Silica-reinforced S-SBR/BR tire tread compounds often show characteristic vulcanization profiles that do not exhibit a distinct maximum in the cure curve nor a plateau profile within acceptable time scales (marching modulus). In such a situation, it is difficult to determine the optimum curing time, and as a consequence, the physical properties of the rubber compounds may vary. Previous studies stated that the curing behavior of silica-filled rubber compounds is related to the degree of filler dispersion, the silanization, and the filler–polymer coupling reaction, as well as to the donation of free sulfur from the silane coupling agent. Such results imply that these are the key factors for minimization of the marching modulus. Various silane coupling agents with different sulfur ranks and functionalities were mixed at varied silanization temperatures. The correlation between these factors and their effect on the marching modulus intensity (MMI) were investigated. The MMI was monitored by measuring the vulcanization rheograms using a rubber process analyzer at small (approximately 7%) and large (approximately 42%) strains to discriminate the effects of filler–filler and filler–polymer interactions on the marching modulus of the silica-filled rubber compounds. Both factors have an intricate influence on the marching modulus, determined by the degree of filler–filler interaction and the coupling agent.

Abstract:
The power generation, transmission and utilisation are necessarily being carried out at different voltage levels, and require transformers for performing the voltage level conversions. As a result, transformers form one of the most critical elements of the power system. Incidentally, they are also one of the costliest equipments in any electric power stations, with cost ranging up to millions of dollars. Their repair work also proves to be quite expensive and time consuming. Moreover, the revenue loss due to the consequential line outages can be intolerable. The electrical insulation in the transformers age under electrical, thermal, mechanical and synergy of these stresses. The electrical stresses are due to the continuous operating voltage, temporary overvoltages and the transient overvoltages. Classically, the surges generated by switching operation and natural lightning formed mainly the transient overvoltages. An adequate design of the transformer insulation requires a detailed knowledge on the electrical stress distribution all along the winding. Unlike that in simple airgaps found in the transmission lines, the transformer winding complicates the stress distribution by modulating its spatio-temporal distribution. This necessitated a detailed modelling of the winding, well beyond the normal two-port network model employed in power system studies. Both distributed and ladder network models have been proposed in the earlier literature to accurately depict the response of the simplified winding models for fast rising lightning and switching surges. Depending on the adopted model, varieties of theoretical approaches ranging from travelling and standing wave theory-based approaches to finite-difference-equation based approaches, have been proposed. With the advent of digital computers, ladder network models assumed priority and non-uniform winding could be modelled. There was also another experimental based approach in which the frequency or time domain response of the winding at its terminals (and taps if made available) were measured and various system identi fication approaches were attempted to either describe the terminal response for different surges or use it for possible identification of the physical (geometric) changes in the winding structure. However, as this approach cannot be employed for the winding that are yet to be fabricated and further cannot provide any insight into various interior stresses, they will not be considered hereafter. With the increase in power rating of the transformers, the size of the winding also became bigger. Then the adequacy of the above said modelling approaches for analysing the stress under the chopped lightning impulse was questioned. Meanwhile, the propagation of the Partial Discharge (PD) pulse, which can have rise time of the order of few nanoseconds, could not be e ectively analysed by the classical approaches. With the advent of Gas Insulated Substation (GIS), another overvoltage called the Very Fast Transient Overvoltage (VFTO), caused by the operation of mainly the disconnector switches became a matter of concern. These overvoltages have frequency spectrum ranging up to tens to hundreds of MHz. The higher frequency content of the above said entities have led to serious concern over the validity of the circuit-based modelling. To overcome the problem, transmission line modelling for the turns/coils of the winding were proposed and commonly employed. In this approach, both Single Transmission Line model (STL) and Multi-Conductor Transmission Line Model (MTL) were adopted to evaluate the surge distribution along the winding. The same was also employed for the modelling of the propagation of PD pulses. However, the transmission line modelling requires the existence of Transverse Electro Magnetic (TEM) mode of wave propagation, which is rather di cult to realise for the initial critical part of VFTO and for the entire PD waveforms. Incidentally, the laboratory validation provided in some of the literature were plagued by the electromagnetic scaling issues, which render the validation provided quite inadequate. In other words, it has become highly essential to trace the underlying dynamic electromagnetic fields, rather than resorting to convenient simplified modelling approaches. The present work was taken up to address this basic problem. Its scope is identified as: (i) Find a suitable numerical electromagnetic field calculation approach for the problem in hand, and (ii) Noting that the circuit-based modelling is the language of electrical engineers, provide an upper frequency bound to such modelling approaches for the transformer windings. Simplifications which are routinely made in evaluating the surge response of the windings like neglecting role of bushing, tank and other phases, are also made in this work. At the same time, it is worth noting here that the present work can be considered as a first step in finding the full-wave response of windings

Abstract:
The final chapter reviews the key findings of the book, and reflects on the future direction of digital campaigning. The main conclusions are threefold: (1) Developments in digital campaigning follow a similar pattern across countries. A four-stage cycle of experimentation, standardization, community building, and individual voter mobilization is clearly evident across the book’s four case studies. (2) The pace of that development and countries’ current positions differ according to regime-level characteristics and levels of national technological advancement. Notably, parties and individual candidates can also play a significant role in shaping that process. In particular, mainstream leftist parties and some of the more prominent minor parties serve as key catalysts for change. (3) The “mainstreaming” of digital technology is fostering the growth of a new type of campaign operative—the apolitico—and a new condition of hypernormality in which power is centralized organizationally and systemically to an unprecedented degree.

"very easy for sensitive medical information to be accessed and sold by unscrupulous individuals that had access to the DNA database. Not only that, but with the increasing use of DNA in medical situations, the absolute protection of results of analysis cannot be guaranteed against seizure by law enforcement agencies. An interesting aspect to refusing to give a sample voluntarily is that such refusal raises an air of suspicion. This in turn gives an aspect to proceedings in court which move from innocent until proved guilty towards guilty until exonerated by DNA. This is simply not how it should be. The more and more samples on the DNA database, the more likely it becomes that a chance match results in a wrongful conviction. As of early 2004, Canada and France have shown a greater degree of responsibility than the progressive belief of the Forensic Science Service that they can get away with any infringement of what is very personal information. What Canada and France have done is made it mandatory that samples from accused persons who are subsequently not charged or acquitted should not be retained. Even more sensible, if samples are taken from juveniles, even if convicted, they will be destroyed when the individual becomes a legal adult. As we in the UK seem to be marching towards institutional control of our most personal information, American law enforcement agencies are astonished that in the land of the free we seem to have no interest in a public debate of what might become not just control of information, but control of the individual. 2 Cloning as a legal issue."
