High Quality Content by WIKIPEDIA articles! The Sikorsky S-61R is a twin-engine helicopter used in transport or search and rescue roles. A developed version of the S-61/SH-3 Sea King, the S-61R was also built under license by Agusta as the AS-61R. The S-61R served in the United States Air Force as the CH-3C/E Sea King and the HH-3E Jolly Green Giant, and with the United States Coast Guard as the HH-3F "Pelican". The Sikorsky S-61R was developed as a derivative of their S-61/SH-3 Sea King model. It features a substantially-revised fuselage with a rear loading ramp, a conventional though water-tight hull instead of the S-61's boat-hull, and retractable tricycle landing gear. The fuselage layout was used by Sikorsky for the larger CH-53...

High Quality Content by WIKIPEDIA articles! High Quality Content by WIKIPEDIA articles! Silica gel is a granular, vitreous, highly porous form of silica made synthetically from sodium silicate. Despite its name, silica gel is a solid. It is a naturally occurring mineral that is purified and processed into either granular or beaded form. As a desiccant, it has an average pore size of 24 angstroms and has a strong affinity for moisture molecules. Silica gel is most commonly encountered in everyday life as beads packed in a vapor-permeable plastic. In this form, it is used as a desiccant to control local humidity in order to avoid spoilage or degradation of some goods. Because of poisonous dopants (see below) and their very high absorption...

In vehicle design and evaluation, crashworthiness is one of the most important criteria. In order to save time and expense, the real vehicle crash tests have been simulated and performed through computer using finite element method since late 1980's. As the vehicle structure becomes more complicated, the size of the respective finite element vehicle model highly increases. The computer simulation therefore consumes a larger amount of computer resources and takes much longer time when using a detailed finite element model. This book provides a new methodology of developing simplified finite element models for the vehicle crashworthiness analysis. The simplified models presented in this book significantly increase the efficiency of the...

The Turkish Straits, which are comprised of the Strait of Istanbul, the Strait of Canakkale and the Sea of Marmara, are one of the most strategically important waterway systems in the world. The Straits have a very narrow and winding shape that gives them the semblance of a river. In fact, they are one of the most hazardous and difficult to navigate waterways in the world. Together with these geographical properties, especially regarding the Strait of Istanbul, local meteorological conditions, dense and increasing transit and local traffic, vessel and cargo characteristics and a city with immense cultural heritage and 10 million plus population surrounding it, greatly increase the risks associated with maritime activities.

Floods can play great havoc including loss of life, damage to property and agricultural crops, health hazards and disruption of human. The information such as peak flow and its volume are required in the design phase of irrigation, hydro-power and flood control projects. Hydrological models are widely used for the computation of flows in response of precipitation in the catchment and help to understand the characteristics behavior of a stream over a long period of time. The inputs for such models include long term records of stream flow, meteorological data and catchment characteristics. This book includes hydrological analysis of the Kanshi River catchment in Pakistan using TOPMODEL. The model predicts catchment water discharge and...

It is possible to estimate the elastic properties of underwater sediments using single-channel seismic profiling. The task is greatly simplified if the data are recorded using a geometry that minimizes the horizontal distance between seismic source and hydrophone receiver. This produces signal ray paths that are approximately perpendicular to sediment interfaces and thereby promotes a significant reduction in mathematical complexity. It also promotes well-developed sequences of seismic wavelets that reverberate between interfaces. The amplitudes and phases of individual wavelets in such sequences encode values of propagation parameters such as bulk densities and reflection/absorption coefficients. By analyzing amplitudes and phases, it...

Miniaturization and power demands of future portable electronic devices require the development of high-power density, easily rechargeable and smallscale power sources. Single-chamber solid oxide fuel cells (SC-SOFCs) constitute a promising approach as the use of a mixture of fuel and oxidant permits simplification of conventional fuel cell systems and development of new cell configurations such as coplanar micro-electrode designs, where microscale anode and cathode are both situated on the same side of the electrolyte. However, the working principles of SC-microSOFCs are not yet fully understood, partly due to the lack of suitable fabrication techniques. In this book, a direct-write microfabrication method was evaluated for creating...

Precision measuring instruments with nanometer resolution are almost always susceptible to disturbance transmitted mainly from ground vibration as well as other sources such as acoustic noise and direct mechanical vibrations. Even though the instrument itself is designed to handle such disturbances, researchers in this field are still in need of a smart way to properly eliminate this problem so that they can make their measurement results more trustworthy. In this book the proposed solution is to use a hybrid active-passive vibration isolation system between the instrument and ground to eliminate vibration transmitted from ground as well as direct disturbances transmitted from the moving parts of the instrument to the support plate of...

High Quality Content by WIKIPEDIA articles! The six-stroke engine is a type of internal combustion engine based on the four-stroke engine, but with additional complexity to make it more efficient and reduce emissions. Two different types of six-stroke engine have been developed since the 1990s: In the first approach, the engine captures the heat lost from the four-stroke Otto cycle or Diesel cycle and uses it to power an additional power and exhaust stroke of the piston in the same cylinder. Designs use either steam or air as the working fluid for the additional power stroke. The pistons in this type of six-stroke engine go up and down three times for each injection of fuel. There are two power strokes: one with fuel, the other with...

Sleeve-valve engines saw use in a number of pre-World War II luxury cars, sports cars, the Willys-Knight car and light truck, the British Daimler and French Avions Voisin luxury cars, also used the same Willys-Knight double-sleeve system. They subsequently fell from use due to advances in poppet-valve technology (sodium cooling) and to their tendency to burn a lot of lubricating oil or to seize due to lack of it. The Scottish Argyll company used its own, much simpler and efficient, single-sleeve system in its cars, a system which, after extensive development, saw substantial use in...

Control problems involving mobile robots have attracted considerable attention in the control community. In industrial and manufacturing applications, time and speed are very important parameters when calculating the productivity and efficiency of a process. Hence, in the trajectory-tracking control problem it is a requirement that the mobile robots be able to track a time-indexed trajectory. In such cases motion control is commonly achieved with a velocity profile. The present work addresses sliding-mode control of non-holonomic vehicles, and more specifically trajectory-tracking case. A set of experimental tests using an intelligent wheelchair, called RobChair, has been performed to evaluate the performance of the sliding-mode...

This book uses the upper bound limit analysis for determination of stability numbers for a two-layered soil slope both for an associated flow rule material and for a homogeneous slope with non-associated flow rule material. The effect of the pore water pressure and horizontal earthquake body forces was also included in the analysis. The results have been given in the form of non-dimensional stability charts, which can be used for readily obtaining either the value of the critical height or the factor of safety. An attempt has also been made in this book to study experimentally the effect of the frequency of the excitation and the addition of non-plastic fines on the liquefaction resistance of the material.
