This research is concerned with analytical modelling of the effects of cracks in structural plates and panels within aerospace systems such as aeroplane fuselage, wing, and tail-plane structures, and, as such, is part of a larger body of research into damage detection methodologies in such systems. This study is based on generating a so-called reduced order analytical model of the behaviour of the plate panel, within which a crack with some arbitrary characteristics is present, and which is subjected to a force that causes it to vibrate. In practice such a scenario is potentially extremely dangerous as it can lead to failure, with obvious consequences. The equation that is obtained is in the form of the classical Duffing equation, in this case, the coefficients within the equation contain information about the geometrical and mass properties of the plate, the loading and boundary conditions, and the geometry, location, and potentially the orientation of the crack Plate.
In the mobile radio environment, base stations are installed at the location where the coverage area receives adequate signal power that makes the communication possible. However, due to the nature of wave propagation and the natural features of the environment, such as valleys or the shadows of intervening mountains, as well as man-made objects such as tunnels or high-rise buildings in the vicinity of wave propagation, severe fading of the signal amplitude will result, creating dead spots areas. These areas need to be patched, especially in prime or high-populated traffic areas. A good reliable signal can be obtained by installing an additional base station, but this approach would increase the signalling complexity by increasing handover between cells. Furthermore, it is not cost effective to build an additional BS to patch a small shadow area, due to the high network investment that would be required. An alternative to patching these areas is by using On-Frequency repeaters, also known as Cell Enhancers, as they constitute much simpler and cheaper techniques as well as involving shorter “off-air” periods for obtaining reliable radio coverage.
Any modern industrial manufacturing unit inevitably faces problems of vagueness in various aspects such as raw material availability, human resource availability, processing capability and constraints and limitations imposed by marketing department. This problem has to be solved by a methodology which takes care of such fuzzy information. As the analyst solves this problem, the decision maker and the implementer have to coordinate with the analyst for taking up a decision on a successful strategy for implementation. Such a complex problem of vagueness and uncertainty can be handled by the theory of fuzzy logic.In this book, a new fuzzy logic based methodology using a specific membership function, named as modified S-curve membership function is proposed. The modified S-curve membership function is first formulated and its flexibility in taking up vagueness in parameters is established by an analytical approach.The usefulness of this modified S-curve membership function is further established using a real life industrial production planning of a chocolate manufacturing unit.
With the advent of new high data rate wireless applications, as well as growth of existing wireless services, demand for additional spectrum is rapidly increasing. Existing “command-and-control” spectrum allocations defined by government regulatory authorities, such as federal communications commission (FCC), prohibit unlicensed access to licensed spectrum, constraining them instead to several heavily populated, interference-prone frequency bands. Though several report shows that still the spectrum is not utilized efficiently across time and frequency. To use spectrum efficiently, a new intelligent wireless communication system has been developed termed as cognitive radio network. Multi-carrier techniques, such as orthogonal frequency division multiplexing (OFDM) transceiver have a big role in such advance wireless standard. However an OFDM or NC-OFDM may have several subcarriers that are deactivated i.e. zero valued input that means many FFT calculations are there which are not required at all. So the hardware resources of the FFT are not fully being exploited. Therefore a new approach of FFT pruning algorithm has been very much required where several subcarriers are deactivated.
For centuries, science and religion have been portrayed as diametrically opposed. In this provocative new book, Steve Fuller examines the apparent clash between science and religion by focusing on the heated debates about evolution and intelligent design theory. In so doing, he claims that science vs. religion is in fact a false dichotomy. For Fuller, supposedly intellectual disputes, such as those between creationist and evolutionist accounts of life, often disguise other institutionally driven conflicts, such as the struggle between State and Church to be the source of legitimate authority in society. Nowadays many conservative anti-science groups support intelligent design theory, but Fuller argues that the theory's theological roots are much more radical, based on the idea that humans were created to fathom the divine plan, perhaps even complete it. He goes on to examine the unique political circumstances in the United States that make the emergence of intelligent design theory so controversial, yet so persistent. Finally, he considers the long-term prognosis, arguing that the future remains very much undecided as society reopens the question of what it means to be human. This book will appeal to all readers intrigued by the debates about creationism, intelligent design and evolution, especially those looking for an intellectually exciting confrontation with the politics and promise of intelligent design theory.
The availability of advanced information technologies such as the various types of automatic data acquisitions and sensor systems has created a tremendous capability to collect valuable process data. The effective and timely processing of this data is the backbone of intelligent process monitoring and control. The need for more practical process monitoring models continues to grow as these technologies become more sophisticated. This book presents effective methods for processing sensor data in order to achieve intelligent process monitoring and control strategies. In developing these methods, the following issues were considered: (a) how to represent secondary data in such a way that the features conserve the condition information essential for real-time decisions; (b) how to obtain a set of parsimonious features that are able to capture new information and also preserve the condition information in the original data; and (c) how to reduce the uncertainty in selecting subset features for prediction purposes. The book is an indispensable resource for researchers, professionals, and graduate students in industrial engineering, manufacturing, and related fields of study.
Global positioning system (GPS) is actively employed in a variety of vehicular monitoring systems utilizing advanced technologies like Global System for Mobile communication (GSM), Geographical Information System (GIS), General Packet Radio Service (GPRS) and Radio frequency Identification (RFID). It is generally observed that passengers who use fixed transportation facility everyday have to wait for long time at their residence even though the timing is fixed. Due to reasons like traffic congestion as well as delay incurred due to other passengers, the reaching time of such vehicles at different users’ location is not remaining fixed as per the defined schedule. Hence it is required that such transportation vehicles should be equipped with an intelligent system that can inform to each user in advance about the expected arrival time of the vehicle at user’s residence. Such a system referred as Bus Information System can help the people avoiding waiting for longer at the entry gate of the societies where they live. Such a system helps in saving people's time waiting for the transportation vehicle.

As everybody knows cancer is a global problem and its prevalence will increase dramatically over the next decade, especially in the developing world. In many developing countries, cancer treatments such as radiation are only available at a few sites nationally and often in just one city. In order to successfully implement an appropriate quality assurance program for treatment planning, adequate resources must be allocated. This limits the need of quality control program and treatment dose accuracy. Hence access, quality and efficiency of radiotherapy service in developing countries must be understood to advance effective cancer control programs. Researches based on these can provide insight in these areas.
The present method of predicting resistance and powering for fishing vessel such as the trawler or purse seiner lend itself to various sources of errors and do not provide an accurate solution to the problem. Model-ship correlation study plays an important role in the accuracy of ship powering prediction from model testing. The outcome of the result from the model testing can be utilized in order to determine the accuracy of the various methods employed for predicting resistance and powering for trawler/purse seiner. Non-dimensional relationships, such as Froude number and resistance-displacement ratio, are used for the model-ship correlation.
