Reliability analyses for complex engineering systems inevitably involve uncertainties. Uncertainty management is essential for practical usability and credibility of reliability based decision making. An overview of the basic concepts of uncertainty propagation, together with simple and practical illustrations is presented. The issues of uncertainty management addressed in this book include: identifying the sources of uncertainty in reliability analyses, characterizing them at the element level, propagating them to the system level, recommending ways to handle the important contributors, and taking decisions in the light of uncertainties. All these issues are discussed with several case studies from nuclear power plants including...

Unconventional oil is petroleum produced or extracted using techniques other than the traditional oil well method. Unconventional oil production is less efficient and has more environmental impacts than conventional oil production. Oil Industries and governments are investing in unconventional oil sources due to the increasing scarcity of conventional oil reserves.Unconventional sources of oil will be increasingly relied upon as motor fuel for transportation when conventional oil becomes "economically non-viable" due to depletion. Conventional sources of oil are currently preferred because they provide a much higher ratio of extracted energy over energy used in extraction and refining processes. Technology, such as using steam injection...

High Quality Content by WIKIPEDIA articles! Template:WindTurbineSegments As of 2012, the most common type of wind turbine is the three-bladed upwind horizontal-axis wind turbine (HAWT). This article deals with various types of wind turbine that differ from the standard type. Some types have had limited commercial use, while others have only been demonstrated or are only theoretical concepts with no practical applications.

Underwater habitats are underwater structures in which people can live for extended periods and carry out most of the basic human functions of a 24-hour day, such as working, resting, eating, attending to personal hygiene, and sleeping. In this context 'habitat' is generally used in a narrow sense to mean the interior and immediate exterior of the structure and its fixtures, but not its surrounding marine environment. Most early underwater habitats lacked regenerative systems for air,...

Underactuated mechanical systems have fewer independent actuators than the number of degrees of freedom. This thesis establishes the formal link between nonminimum phase and underactuation and proposes suitable control techniques. Two-link underactuated mechanical systems without friction are shown to be nonminimum phase for those outputs that i) correspond to an arbitrary combination of the coordinates, and ii) are small-time locally controllable. On the control side, the forces present in these systems are separated into two categories, namely the actuator forces (direct effect of the input), and the state-dependent forces (integral effect of the input) such as gravity, Coriolis, centrifugal and possibly aerodynamic forces. The first...

The use of advanced ceramics like silicon nitride can be found in many high-tech engineering applications in various fields such as aerospace, defense and automotive. In order for these ceramics to become more prevalent in industry, development of better and cheaper methods of manufacturing ceramic parts is essential. Laser-assisted machining (LAM) of ceramics is one tool that can enable this growth while maintaining reasonable costs of manufacturing parts in small quantities. This book contains the research conducted on LAM of ceramics that helps develop a complete understanding of various laser and machining parameters in LAM of ceramics, and makes some important conclusions that help in continuing the research for a fully developed...

It is well known that undershoot phenomena are inevitable for plants having real unstable zeros. This book, firstly investigate the undershoot phenomena caused by unstable zeros of the plant to be controlled theoretically. Then, propose methods of reducing the undershoot amount for a plant with unstable zeros by digital control. The ideas are based on the Linear Quadratic Regulator (LQR) design is to use a modified performance index with an exponential time decay rate using a weighting factor and confirm from simulation results that the weighted optimal LQR can reduce undershoot in comparison with the standard LQR case.?The next method to reducing the undershoot amount is by using digital control design. The idea here is a combination of...

An underwater glider is a type of autonomous underwater vehicle (AUV) that uses small changes in its buoyancy in conjunction with wings to convert vertical motion to horizontal, and thereby propel itself forward with very low power consumption. While not as fast as conventional AUVs, gliders using buoyancy-based propulsion represent a significant increase in range and duration compared to vehicles propelled by electric motor-driven propellers, extending ocean sampling missions from...

Unexploded ordnance (or UXOs/UXBs, sometimes acronymized as UO) are explosive weapons (bombs, bullets, shells, grenades, land mines, naval mines, etc.) that did not explode when they were employed and still pose a risk of detonation, potentially many decades after they were used or discarded. While "UXO" is widely and informally used, munitions and explosives of concern (MEC) is the current preferred terminology within the remediation community. Данное издание не является оригинальным.

Single waves with high amplitudes, sometimes called rogue, or killer waves, appear surprisingly on the ocean and sea surface. Such waves are very dangerous for ships and for coastal structures due to their destructive high steepness and height. Is there ability to creation of these killer unidirectional waves in laboratory channel, in order to future tests of the ships and the coastal structures ability to withstand the impact, was studied. The spatial Zakharov equation is applied in the present study. Evolution of unidirectional nonlinear wave groups with wide spectra was studied experimentally and numerically. A focusing of an initially wide wave train that is modulated into a single steep wave at a prescribed location along the wave...

Currently, when designers develop a building design project, different representations are used for different building subsystems, such as spatial system, electrical system, lighting system, hydraulic system and HVAC. These representations are mainly used in the final design documentation stage. This book presents a qualitative approach to the development of a unified energy-based representation for building analysis called qualitative Archi Bond Graphs (QABGs). QABGs integrate different representations in the architectural domain into a unified representation. They can be applied in the conceptual, intermediate, and final building design stages. Combining graphical representations and qualitative equations, QABGs are applicable for...

Uniform tilings can exist in both the Euclidean plane and hyperbolic plane. Uniform tilings are related to the finite uniform polyhedra which can be considered uniform tilings of the sphere. Most uniform tilings can be made from a Wythoff construction starting with a symmetry groups and a singular generator point inside of the fundamental domain. A planar symmetry group has a polygonal fundamental domain and can be represented by the group name reprsented by the order of the mirrors in sequential vertices.

Unless with Multilateration, the system concept primarily addresses simply the simple question of here or not here up to the quality of close or far and serves the binary answer yes or no respectively the crossing of a scaled threshold. Optionally this quality may be enhanced with some information about the distance between the locating item and the located item.
