Sensor Network is potentially powerful tool for analysis of surface properties in much larger areas and also areas which are inaccessible because of its unique capability of deployment & autonomous data gathering in unfriendly and unattended environment. Also optimization of sensing circuits in terms of mass, power and size will eventually increase the efficiency of sensor network. An attempt has been made to design a sensor network for measurement of temperature for surface analysis and this book will help beginners to understand about sensor networks and power optimization.
The book investigates the topic of eco-sustainable supply chain network design. Supply chain optimization possesses tremendous potential for minimizing greenhouse gas emissions, thus contributing to an improved ecological lifecycle and potentially lowering energy expenses. One promising pillar of sustainable SC optimization is logistics network design. The book provides the reader with a thorough understanding of imminent forces for corporations to embrace the challenge of addressing emissions in their supply chain strategies. As a fundamental basis, the principle of carbon footprint is presented and important models for CO2 emission calculation against the background of network design are elucidated. The book presents strategic network design principles focussing on sustainable network location planning. Proven models for logistics network design are presented and extended by the novel target dimension of CO2 reduction. Combining the components of network design and emission reduction, the book provides supply chain strategists with a practical evaluation of eco-sustainable network optimization, applying network optimization software in a case study for a European consumer goods manufacturer. The analysis provides insights into the potential and the associated trade-offs for optimizing supply chain networks with the goal of eco-sustainability and cost effectiveness.
Network recovery is critical capability that service providers must provide. It can be accomplished in four ways. Span, or local, protection is the most common recovery method. Another common method is path restoration which is accomplished end-to-end. Some service providers apply both span protection and path restoration in different parts of their networks in a “hybrid” configuration. Another more recent alternative is a feature in Multiprotocol Label Switching (MPLS) called “Fast Reroute.” This praxis addresses several fundamental problems related to each of the above network recovery options in large service provider networks. First, the effects of the numbers of links, demand unit sizes, and link size modularity have on the four recovery methods, individually and collectively, are examined. Next, the selection of the minimum cost recovery method given the presence and levels of the other options is determined. Finally, the cost differences of the recovery methods given any combination of the other options and their levels are presented.

This book presents novel approaches for efficient optimization techniques based on numerical simulations for photonic devices. It presents the recent advances in the application of the adjoint variable method to photonic devices as an efficient technique for sensitivity analysis. It also presents novel approaches for formulating the design of any photonic devices as an optimization problem. These optimization problems are then solved efficiently using gradient-based optimization algorithms. This book is the first one that shows how the optimization problem can be formulated as a convex optimization problem in photonics. Convex optimization programming allows for efficient solution of the design problem using interior point method. These approaches will highly accelerate the design cycle of novel structures to meet the ever demanding requirements of the photonic devices.
Nonnegative systems play an important role in various fields such as (bio)chemistry, economy, population dynamics or even in transportation modeling where the state variables of the models are often physically constrained to be nonnegative. The aim of this book is to summarize and present computation based analysis results for certain classes of nonnegative models that are primarily applied in the description of biochemical processes, and are given in the form of nonlinear ordinary differential equations. Majority of the developed analysis methods are put into an optimization framework, and they include the stability analysis and control of quasi-polynomial systems, and the computation of preferred reaction network structures from kinetic system models.
Although the overall appearance of modern airliners has not changed a lot since the introduction of jetliners in the 1950s, their safety, efficiency and environmental friendliness have improved considerably. Main contributors to this have been gas turbine engine technology, advanced materials, computational aerodynamics, advanced structural analysis and on-board systems. Since aircraft design became a highly multidisciplinary activity, the development of multidisciplinary optimization (MDO) has become a popular new discipline. Despite this, the application of MDO during the conceptual design phase is not yet widespread. Advanced Aircraft Design: Conceptual Design, Analysis and Optimization of Subsonic Civil Airplanes presents a quasi-analytical optimization approach based on a concise set of sizing equations. Objectives are aerodynamic efficiency, mission fuel, empty weight and maximum takeoff weight. Independent design variables studied include design cruise altitude, wing area and span and thrust or power loading. Principal features of integrated concepts such as the blended wing and body and highly non-planar wings are also covered. The quasi-analytical approach enables designers to compare the results of high-fidelity MDO optimization with lower-fidelity methods which need far less computational effort. Another advantage to this approach is that it can provide answers to “what if” questions rapidly and with little computational cost. Key features: Presents a new fundamental vision on conceptual airplane design optimization Provides an overview of advanced technologies for propulsion and reducing aerodynamic drag Offers insight into the derivation of design sensitivity information Emphasizes design based on first principles Considers pros and cons of innovative configurations Reconsiders optimum cruise performance at transonic Mach numbers Advanced Aircraft Design: Conceptual Design, Analysis and Optimization of Subsonic Civil Airplanes advances understanding of the initial optimization of civil airplanes and is a must-have reference for aerospace engineering students, applied researchers, aircraft design engineers and analysts.
Design and Analysis of Composite Structures enables graduate students and engineers to generate meaningful and robust designs of complex composite structures. Combining analysis and design methods for structural components, the book begins with simple topics such as skins and stiffeners and progresses through to entire components of fuselages and wings. Starting with basic mathematical derivation followed by simplifications used in real-world design, Design and Analysis of Composite Structures presents the level of accuracy and range of applicability of each method. Examples taken from actual applications are worked out in detail to show how the concepts are applied, solving the same design problem with different methods based on different drivers (e.g. cost or weight) to show how the final configuration changes as the requirements and approach change. Provides a toolkit of analysis and design methods to most situations encountered in practice, as well as analytical frameworks and the means to solving them for tackling less frequent problems. Presents solutions applicable to optimization schemes without having to run finite element models at each iteration, speeding up the design process and allowing examination of several more alternatives than traditional approaches. Includes guidelines showing how decisions based on manufacturing considerations affect weight and how weight optimization may adversely affect the cost. Accompanied by a website at www.wiley.com/go/kassapoglou hosting lecture slides and solutions to the exercises for instructors.
