High Quality Content by WIKIPEDIA articles! Optimal matching is a sequence analysis method used in social science, to assess the dissimilarity of ordered arrays of tokens that usually represent a time-ordered sequence of socio-economic states two individuals have experienced. Once such distances have been calculated for a set of observations (e.g. individuals in a cohort) classical tools (such as cluster analysis) can be used. The method was tailored to social sciences from a technique originally introduced to study molecular biology (protein or genetic) sequences (see sequence alignment).

Traditional mathematical optimization methods, such as linear programming (LP), nonlinear programming (NLP) and dynamic programming (DP), often have drawbacks in practice. To overcome these drawbacks, various meta-heuristic optimization techniques have been developed. This study proposes a new meta- heuristic algorithm which mimics musical performance, and names as Harmony Search (HS). The HS algorithm is applied to five problems: a continuous function optimization, a hydrologic parameter calibration, a traveling salesman problem, an optimal design of water supply network, and an optimal expansion of water supply network. The comparison of solutions obtained by HS and other optimization techniques shows that the HS algorithm can find...

Anatomically based mathematical models are readily developed to understand how strategic displacements of the eyes and head are controlled by the brain. One of the most lacking aspects of such models and in fact one of the least understood aspects of oculomotor control is a comprehensive switching mechanism for alternating between slow and fast phase movements. The switching mechanism put forward in this book is designed to accurately decide when one phase should be ended and the other initiated (fusing slow and fast phases) in all types of behaviorally observed eye and head movements. This offers a novel and powerful option for improving exisiting gaze shift models. It furthermore has important implications in both biomimetic control...

We are today in the era of gigascale 2D and 3D integrated circuits. These microchips are typically considered to be "interconnect limited", with performance limited by signal, power, clock and thermal interconnect networks. Techniques to tackle this interconnect challenge are proposed and quantitatively evaluated in this book. Topics described by the author include integrated microchannel cooling of 3D stacked dice, repeater insertion models, carbon nanotube interconnects, parallel processing architectures, electromigration avoidance methods and a CAD tool to co-design signal, power, clock and thermal interconnect networks of microchips. This book should be especially useful to students and professionals in the areas of microelectronics,...

High Quality Content by WIKIPEDIA articles! Optimal control deals with the problem of finding a control law for a given system such that a certain optimality criterion is achieved. A control problem includes a cost functional that is a function of state and control variables. An optimal control is a set of differential equations describing the paths of the control variables that minimize the cost functional. The optimal control can be derived using Pontryagin's maximum principle (a necessary condition), or by solving the Hamilton-Jacobi-Bellman equation (a sufficient condition).

Maximizing airline profit is challenging as several costs, such as fuel or manpower, have been increasing. Fierce competition has forced airlines to drastically reconsider their economic policy. Traditional revenue management techniques such as overbooking or dynamic pricing have been utilized to improve profit of the airline industry. Yet, market finance and its dynamic fast-pace modeling inspire a different approach to airline revenue maximization. This work proves the efficiency of using financial options theory, considering only two standard types of options (call options and put options). The demand distribution and the random walk of a ticket price cause uncertainty in the booking process. A numerical search method is used to...

Optimization methods are increasingly used to design structures. Structural optimization with linear static analysis is pretty much mature in methodology and therefore several codes now have optimization capability for linear analysis. This is in contrast to optimization with crash and impact responses encountered in automotive, defense, transportation safety and other fields. Impact responses do not present simplicities as with linear static responses. They are highly nonlinear and noisy (i.e. non smooth) preventing the use of conventional optimization methods based on gradients or sensitivities. Also, impact analyses are usually computationally costly. Such difficulties motivated the development of effective and efficient methods for...

Despite the significant progress made in the past three decades towards a comprehensive understanding of the processes and phenomena related to pavement deterioration and performance, it is freely admitted that a considerable gap in engineering knowledge will continue to persist well into the 21st century. Understanding pavement performance is a complex mission because pavement performance is controlled by many factors. Many studies have been conducted to answer a simple twofold question; how pavement performs and why it performs in this manner? This big question took the road agencies tens of years of research and investigations to answer and still no remedy answers have been found yet. This situation is true due to the fact that...

The optimal shape is found for structures that can be characterised by an order of hierarchy or branching (examples of such structures include tower cranes and the Eiffel tower). The objective is to determine the circumstances in which higher order structures become optimal. It is of specific interest whether these solutions change when imperfections are included. For hierarchical structures, imperfections can exist at the local and global scales, and this interaction of imperfections across different orders of magnitude causes a strength reduction that is greatest at the optimal shape found by analysing a perfect structure. It is therefore essential to include the imperfections within the optimisation algorithm, because they change the...

Die grundlegende Idee der optischen korrelationsbasierten Messtechnik besteht darin, die lokale Kreuzkorrelation zur Losung des Korrespondenzproblems anzuwenden. Dazu wird ein zufalliges, und dadurch eindeutig zu korrelierendes, Punktemuster mittels einer digitalen Kamera aufgenommen. Die Auswertung des so gewonnenen Bildpaares erfolgt mit Hilfe von Kreuzkorrelationsalgorithmen auf Basis von raumlichen Auswertefenstern. Dieser Ansatz zur Losung des Korrespondenzproblems ist schnell, eindeutig und robust. Im Rahmen dieser Arbeit wird ein Schwerpunkt auf die Untersuchung der Algorithmen zur Sub-Pixel-Detektion gelegt. Es wird gezeigt, dass die bisherigen Algorithmen im Falle elliptischer Korrelationsmaxima einen systematischen Fehler...

Optische Isolatoren gewinnen in der Lasermaterialbearbeitung immer mehr an Bedeutung, da die eingesetzten Strahlquellen zum Teil sehr empfindlich auf Ruckreflexe, zum Beispiel vom zu bearbeitenden Werkstuck, reagieren konnen. Diese Arbeit beschreibt einen moglichen Ansatz einer fasergekoppelten Isolatoranordnung fur unpolarisierte Nd:YAG-Laserstrahlung hoher mittlerer Leistung. Oft stehen bei Strahlfuhrungskomponenten fur sehr hohe Laserleistungen die thermischen Effekte, bedingt durch Absorption in den optischen Elementen, die direkt mit dem Laserlicht in Wechselwirkung treten, im Vordergrund, da sie die Leistungsfahigkeit bzw. Effizienz derartiger Systeme stark beeintrachtigen konnen. Die experimentelle Untersuchung der thermischen...

A directory service is the software system that stores, organizes and provides access to information in a directory. In software engineering, a directory is a map of the differences between names and values. It allows the lookup of values given a name, similar to a dictionary. As a word in a dictionary may have multiple definitions, in a directory, a name may be associated with multiple, different pieces of information. Likewise, as a word may have different parts of speech and different definitions, a name in a directory may have many different types of data....

Orbital elements are the parameters required to uniquely identify a specific orbit. In celestial mechanics these elements are generally considered in classical two-body systems, where a Kepler orbit is used. There are many different ways to mathematically describe the same orbit, but certain schemes each consisting of a set of six parameters are commonly used in astronomy and orbital mechanics. A real orbit changes over time due to gravitational perturbations by other objects and the effects of relativity. A Keplerian orbit is merely a mathematical approximation at a particular time.

High Quality Content by WIKIPEDIA articles! Orbital mechanics or astrodynamics is the application of ballistics and celestial mechanics to the practical problems concerning the motion of rockets and other spacecraft. The motion of these objects is usually calculated from Newton`s laws of motion and Newton`s law of universal gravitation. It is a core discipline within space mission design and control. Celestial mechanics treats more broadly the orbital dynamics of systems under the influence of gravity, including both spacecraft and natural astronomical bodies such as star systems, planets, moons, and comets. Orbital mechanics focuses on spacecraft trajectories, including orbital maneuvers, orbit plane changes, and interplanetary...

High Quality Content by WIKIPEDIA articles! In a mixed-order reaction the order of a reaction changes in the course of a reaction as a result of changing variables such as pH. An example is the oxidation of an alcohol to a ketone by a ruthenate (RuO42?) and a hexacyanoferrate, the latter serving as the sacrificial catalyst converting Ru(IV) back to Ru(VI) : the disappearing-rate of the ferrate is zero-order with respect to the ferrate at the onset of the reaction (when its concentration is high and the ruthenium catalyst is quickly regenerated) but changes to first-order when its concentration decreases.

In this book, rigorous techniques for order reduction of nonlinear systems with periodic coefficients are presented. The techniques proposed here construct a reduced order equivalent system by expressing the non-dominant states as time-varying functions of the dominant (master) states. This reduced order model preserves stability properties and is easier to analyze, simulate and control since it consists of relatively small number of states in comparison with the large scale system.

The Ordnance QF 6-pounder 7 cwt, or just 6 pounder, was a British 57 mm gun, their primary anti-tank gun during the middle of World War II, as well as the main armament for a number of armoured fighting vehicles. It was first used in North Africa in April 1942, and quickly replaced the 2 pounder in the anti-tank role, allowing the 25 pounder to revert to its intended artillery role. The United States Army also adopted the 6 pdr as their primary anti-tank gun under the designation 57 mm Gun M1. Данное издание не является оригинальным.

High Quality Content by WIKIPEDIA articles! The Ordnance QF 25 pounder, or more simply, 25-pounder or 25-pdr, was introduced into service just before World War II, during which it served as the major British field gun/howitzer. It was considered by many to be the best field artillery piece of the war, combining high rates of fire with a reasonably lethal shell in a highly mobile piece. It was the British Army's primary artillery field piece well into the 1960s, with smaller numbers serving in training units until the 1980s. Many Commonwealth of Nations countries used theirs in active or reserve service until about the 1970s and ammunition for the weapon is currently being produced by Pakistan Ordnance Factories.

High Quality Content by WIKIPEDIA articles! The Ordnance QF 75 mm, abbreviated to OQF 75 mm, was a British tank-gun of the Second World War. It was used instead of the Ordnance QF 6 pounder ("6 pdr"), an anti-tank gun, to give better performance against infantry targets in a similar fashion to the 75 mm gun fitted to the American Sherman tank. The QF came from "quick-firing". The gun was also sometimes known as ROQF from Royal Ordnance (the manufacturer) Quick-Firing. Данное издание не является оригинальным.

High Quality Content by WIKIPEDIA articles! The Ordnance QF 13-pounder quick-firing field gun was the standard equipment of the British Royal Horse Artillery at the outbreak of World War I. It was developed as a response to combat experience gained in the Boer War and entered service in 1904, replacing the Ehrhard QF 15 pounder and BL 12 pounder 6 cwt. It was intended as a rapid-firing and highly-mobile yet reasonably powerful field gun for Royal Horse Artillery batteries attached to Cavalry divisions, which were expected to be engaged in mobile open warfare. The original Mk I barrel was wire wound. Later Mk II barrels had a tapered inner A tube which was pressed into the outer tube. It saw action most famously at the Battle of Le Cateau...
