Neuware -Geometrical attack degraded the quality of the digital watermarking technique and extracts the watermark symbol form cover image and increases the possibility of piracy of digital multi-media data. Now a day's digital watermarking plays an important role in different multi-media data such as digital image, video, audio, and many more for the protection of piracy of multimedia data. Various authors proposed various methods for enhancement of security strength of watermarking techniques such as DWT, DCT, and pixel-based techniques. 80 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Situated off the southeast coast of Africa, Madagascar is the fourth largest island in the world. Having developed in isolation, the island nation is famed for its unique wildlife. Traditionally, the Malagasy economy has been based on the cultivation of paddy rice, coffee, vanilla and cloves. But, despite a wealth of natural resources and a tourism industry driven by its unique environment, the country remains one of the world's poorest, and is heavily dependent on foreign aid. Since gaining independence from France in 1960, Madagascar has experienced repeated bouts of political instability, including coups, violent unrest and disputed elections. The most recent coup in 2009 led to five years of political deadlock, international condemnation and economic sanctions. This book explores information about Peace and conflict on the 4th biggest island of the World - The Madagascar.

Taschenbuch. Condizione: Neu. Neuware -Every day in modern society people interact with a lot of objects that are created through casting, which is an important technique used by designers, artists and are found in museums where they replace real items that are not readily available or too rare to put on display. The modern industry use various casting techniques to produce things such as toys, car parts, kitchen utensils, jewelry articles and ceramic wares. People around the world have utilized casting as a manufacturing process since 400 BC. The Mesopotamian utilized it to their advantage to cast copper and bronze. The casting process used today is similar to those used in ancient times except for the improvement in technology in terms of materials and techniques (Greer, 2009). In the modern world there is no place without a part or equipment produced by casting such as automotive industry, aerospace, agricultural implements, medical, sculptures and the building industry. Casting involves making a 'mould' or impression of model depending on the application intended and the complexity of the model (Ferreira, 2004). Moulds are divided into two categories depending on the materials used.

Taschenbuch. Condizione: Neu. Neuware -Economic transmission switching is a new practice to improve the economics of electric power systems. Nevertheless, frequently switching lines into or out of service is a disruptive action to the system and can create undesirable effects. In this work, we describe an economic seasonal transmission switching model where transmission switching occurs only once at the beginning of a time period (season) and then the transmission topology remains unchanged during that period. We develop a novel decomposition method that decomposes the seasonal problem into one-hour problems which are then solved efficiently. The dynamic thermal rating is another new technology that utilizes the capacity of power transmission lines based on the ambient factors and the line condition. It usually offers higher thermal capacity than the traditional static rating. We propose a multi-period mixed integer programming model and find the optimal investment plan for the dynamic ratings using Benders Decomposition. Our studies show that the utilization of the dynamic ratings and the practice of transmission switching are complementary and can reduce the costs significantly.

Taschenbuch. Condizione: Neu. Neuware -Flonicamid 50 % WG and buprofezin 25 % SC was showing effective reduction of pest population among all the treatments and found very effective treatments for pests like jassid, thrips, whitefly, aphid on Bt cotton. The rate of reduction of jassid population in imidacloprid 17.8 % SL and Lamda-cyhalothrin 5 % EC was lower than other treatments. Lamda-cyhalothrin 5 % EC and fipronil 5 % SC gave control of whiteflies after each spraying for 3-7 days, but later on the population increased rapidly as compared to other insecticides. Natural enemies observed predominantly on Bt cotton during Kharif 2017-18 were ladybird beetle and chrysopa. Flonicamid 50 % WG, buprofezin 25 % SC, spinosad 45 % SC and spinoterum 11.7 % SC were more safe for ladybird beetle and chrysopa than other insecticides. Pink bollworm damage was more during this Kharif season. Lamda-cyhalothrin 5 % EC found very effective in reducing population of these bollworms, also spinotrum 11.7 % SC, spinosad 45 % SC found and acephate 75 % SC effective against pink bollworm.

Taschenbuch. Condizione: Neu. Neuware -The study demonstrated that many of the symptoms that characterized some forms of depression in humans were presented in experimental animals following endotoxin (LPS) administration. These symptoms included reduced social, exploratory and locomotor activity. Moreover, chronic pre-treatment with hesperidin attenuated or completely abolished these symptoms. This study also provided a leading experimentation concerning the protective in vivo effects of hesperidin on various systems associated with oxidative stress in endotoxemic rat brain and, that may provide excellent protection against several neurodegenerative diseases among other disorders associated with oxidative stress. Our data support the potential value of these agents for the therapy of septic shock. The current report offers compelling, but perhaps not conclusive, arguments for an association between behavioral and brain anatomical changes induced by LPS and its attenuation by hesperidin.

Taschenbuch. Condizione: Neu. Neuware - The text is intended to be used in either a junior or senior engineering design course with an integrated hands-on design project. The whole text is used in the senior capstone design course that includes a complete design project, starting from selecting a market to creating a working prototype.What is design If you search the literature for an answer to that question, you will find about as many definitions as there are designs. Perhaps the reason is that the process of design is such a common human experience. Webster's dictionary says that to design is 'to fashion after a plan,' but that leaves out the essential fact that to design is to create something that has never been. Certainly an engineering designer practices design by that definition, but so does an artist, a sculptor, a composer, a playwright, or any another creative member of our society.Thus, although engineers are not the only people who design things, it is true that the professional practice of engineering is largely concerned with design; it is often said that design is the essence of engineering.

They still run feasibility studies to determine which is the best alternative among different projects that offer the best IRR, VPN, ROI, ROCE, or other financial scoring models. Some projects or programs get rejected because of the value of the alternative chosen is high, and sometimes the process for estimating and budgeting does not obtain the optimum result.The following research suggests the best process for estimating and budgeting that could help owners to get the optimum value for acquiring, constructing, updating, expanding upon, maintaining, repairing, and eventually disposing of organizational assets.Besides, Building Information Modeling (BIM) uses on Integrated Project Delivery (IPD) approach, a collaborative and participatory method. Stakeholders participate in the early stages of the project; this should be a significant differentiator comparing with a traditional cost estimating approach. Has BIM a better process to define the scope and produce a better cost estimate than a traditional method for estimating and budgeting 68 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -A tracking photovoltaic (PV) system constantly adapts the angle of PV modules so that the irradiation angle and the light intensity remain constant and a maximum of electrical energy can be generated. This not only helps to exploit every minute of sunshine but also to make the best use of diffuse light all year round. Due to the changes of the conditions of operation, a tracking PV system shows signs of variation of its parameters. The aim of this research is to analyze the stability of a typical single axes PV system, affected by its parameter variations and improve its performance and robustness. This is achieved by the design of a specialized robust controller and the application of the method of the Advanced D-partitioning. This method for system stability analysis, suggested by the author in 2005, proves to be very efficient for graphical determination of the regions of stability in terms of system's uncertainty or variable parameters. The system robustness is examined after applying the robust controller and the obtained results demonstrate its insensitivity in terms of gain and time-constant variations. 68 pp. Englisch.

Ordination is not only a matter of canons, but of ecclesiology, doctrine, and liturgy as well. The study of the canons can only give hints and clarifying lights in this matter.The exploration of the canonical experience of the Church in order to grasp the modality to answer in certain contextual problems proves to be useful. In the light of these answers we are called ourselves to respond to contemporary pastoral problems. This might be the explanation of one famous quote from Jaroslav Pelikan: ¿tradition is the living faith of the dead and traditionalism is the dead faith of the living¿ 68 pp. Englisch.
