In cellular mobile communication, since there will be conversation in progress in case of handover calls, GOS for them should be less than that for newly originating calls. Basically, there are three channel assignment schemes, fixed, dynamic & hybrid channel assignment schemes for handling newly originating and handover calls. In this study, capacity design for cellular mobile network in area inside ring road in Kathmandu valley has been done according to the findings of data collection and analysis of mobile communication service being provided by Nepal Telecom. Capacity planning has been done with GOS equal to 2% for newly originating calls and 1% for handover calls. In addition to capacity planning, efficient channel assignment...

A new methodology, called predictive dynamics, is introduced in this work to simulate human walking using a spatial digital human model. The digital human model has 55 degrees of freedom. The resultant action of all the muscles at a joint is lumped and represented by the torque at each degree of freedom. In addition, the cubic B-spline interpolation is used for time discretization and the well- established robotic formulation of the Denavit- Hartenberg (DH) method is used for kinematics analysis of the mechanical system. The recursive Lagrangian formulation is used to develop the equations of motion. The ground reaction forces (GRF) are obtained from a novel two-step active- passive algorithm. The problem is formulated as a nonlinear...

Das SWATH-Schiff (SWATH = Small Waterplane Area Twin Hull) ist ein spezieller Schiffstyp, der fur ruhiges Verhalten im Seegang konzipiert wurde. SWATH-Fahrzeuge haben wegen der Doppelrumpfanordnung eine grossere benetzte Oberflache. Daraus resultiert ein hoherer Reibungswiderstand gegenuber konventionellen Schiffen gleicher Grosse. Aufgrund der speziellen Rumpfform bieten SWATH-Schiffe besondere Moglichkeiten zur Gestaltung und Optimierung der Rumpfe. Im Gegensatz zu herkommlichen Schiffen wurden bisher wenige SWATH-Schiffe gebaut. Somit besteht ein Mangel an empirischen Daten zur Optimierung des Widerstands. In dieser Arbeit wurden verschiedene Rumpfformen systematisch variiert und mittels CFD-Rechnungen bezuglich der...

Wegen einer guten Anpassung des elastischen Werkzeugs an die Werkstuckoberflache wird das industrierobotergestutzte Bandschleifen mit elastischer Kontaktscheibe sehr oft fur die Feinbearbeitung von frei geformten Oberflachen verwendet. Der standig wachsende Bedarf an verschiedenen Produkten mit frei geformten Oberflachen erfordert eine Erhohung der Produk-tivitat und der Flexibilitat von automatisierten Anlagen fur die Feinbearbeitung dieser Produkte. Deshalb wird ein neues Softwaresystem entwickelt, welches die Erstellung und Optimierung von Roboterprogrammen bei anspruchsvollen Bearbeitungsprozessen erleichtert. Ein solches Softwaresystem fordert aber ein prazises Prozessmodell, dessen Bildung beim Bandschleifen von frei geformten...

A global trend towards sustainable industry has highlighted a need to source energy and chemicals from renewable feed stocks. A move to farming short-rotation lignocellulosic biomass is one solution to the feed stock problem. However, it is also critical to use a fractionation technology that is appropriate to the biomass type and location. This text details doctoral research on the ethanol organosolv process for fractionation of short-rotation willow. The work is presented in three stages. First, the kinetics of delignification is studied with regard to the important parameters. The effect of prehydrolysis on subsequent organosolv pulping is revealed. Secondly, the easy recovery of organosolv lignin is illustrated with a novel...

Orthographic projection (or orthogonal projection) is a means of representing a three-dimensional object in two dimensions. It is a form of parallel projection, where the view direction is orthogonal to the projection plane, resulting in every plane of the scene appearing in affine transformation on the viewing surface. It is further divided into multiview orthographic projections and axonometric projections. The term orthographic is also sometimes reserved specifically for depictions of objects where the axis or plane of the object is also parallel with the projection plane, as in multiview orthographic projections.

High Quality Content by WIKIPEDIA articles! The Otto engine was a large stationary single-cylinder internal combustion four-stroke engine designed by Nicolaus Otto. It was a low-RPM machine, and only fired occasionally since it was a hit-and-miss engine. Like many engines of the early 1900s, the Otto engine used an open-frame design with all operating cams and levers mounted on the outside of the cylinder head. While this design permits very easy access and observation of all moving components, it also subjects the mechanisms to any dust and moisture in the environment. Consequently this type of machine needs regular cleaning and greasing by an engine operator to keep running correctly, or the levers and gears will eventually seize up...

?-tocopherol and transition metal in scavenging mixture were evaluated as a possible oxygen scavenger. The effects of moisture, amount of transition metal, and thermal processing on oxygen scavenging capability were also investigated. Our results showed that ?-tocopherol and transition metal had 6.72 cc O2/g oxygen scavenging capacity and 0.11 cc O2 /g?day oxygen scavenging rate. Nanoencapsulation technology was adopted for the possible oxygen scavenging activation system. ?-tocopherol-loaded poly ?-caprolactone (PCL) nanoparticles were prepared by O/W emulsion solvent evaporation with ultrasonication. The effect of PCL concentration, solvent in oil phase, and ultrasonication time on encapsulation efficiency (%), particle mean size, and...

It is usually inert, or of a nature that protects the packaged goods, thus inhibiting reactions such as spoilage. Some may also serve as propellant for aerosols like whipped cream.Gas is one of three classical states of matter. Near absolute zero, a substance exists as a solid. As heat is added to this substance it melts into a liquid at its melting point (see phase change), boils into a gas at its boiling point, and if heated high enough would enter a plasma state in which the electrons are so energized that they leave their parent atoms from within the gas.

Similar in function to its smaller cousin, the sedan delivery; which is a station wagon with no backseat, and no side windows aft of the front doors. Both types of vehicles are frequently used as delivery vehicles. Panel trucks are often used by construction and maintenance contractors and were sometimes configured for ambulance and hearse roles. Other variations include Canopy express models, which have open display areas behind the driver's seat primarily used by farmers for selling fruits and vegetables. The evolution of sport utility vehicles can be traced to panel trucks, as the Chevrolet Suburban and GMC Yukon, as well as...

Environmental considerations have become a strategic priority for many companies during the past decade, and the development of new products has had to respond to this trend. Although many methods have been developed for this purpose, much of this effort has found barriers. Environmental assessment is done by using LCA software; engineering design is done in Computer Aided Design (CAD) systems. Both worlds have strong relations – especially when Ecodesign is to be implemented – but they are not necessarily connected. This thesis wants to link both worlds. A framework to integrate LCA into CAD software is developed. The thesis focuses on the translation of LCA results into a judgement of how well or poorly the environmental...

The main objective of this work was to investigate the application of experimental design techniques for the identification of Michaelis-Menten kinetic parameters. More specifically, this study attempts to elucidate the relative advantages/disadvantages of employing complex experimental design techniques in relation to equidistant sampling when applied to different reactor operation modes. All studies were supported by simulation data of a generic enzymatic process that obeys to the Michaelis-Menten kinetic equation. Different aspects were investigated, such as the influence of different reactor operation modes (batch, fed-batch with pulsewise feeding and fed- batch with continuous feeding) and the experimental design optimality criteria...

The Parnell Tunnel is a railway tunnel under Parnell, Auckland, New Zealand. It is 344.5 metres (1,130 ft) long, and allows the Western and Southern lines coming from Newmarket Train Station to Britomart Transport Centre to pass under the Parnell Ridge before the line drops to harbour level. In fact, the Parnell Tunnel is composed of two tunnels, an older single-track tunnel and a newer double-track tunnel, though the entrances to the older tunnel are closed and it has not been in use for most of the last century. The tunnel, originally intended at least in part to provide a connection to Drury for the New...

In many engineering applications there is need to reduce the level of vibrations that are transmitted from a source to a receiver. Amongst several different techniques, the most commonly adopted solution is to interpose an isolation mount between the source and the receiver. Ideally, a vibration isolation mount would have a high static stiffness to prevent too large a static displacement to occur, but a low dynamic stiffness which reduces the natural frequency and extends the frequency range of isolation. For linear mounts these two features are mutually exclusive. However, an improved compromise can be reached by employing nonlinear mounts. In this book the advantages and the limitations of nonlinear isolation mechanisms with a...

Passivity is a property of engineering systems, most commonly used in electronic engineering and control systems. A passive component, depending on field, may be either a component that consumes (but does not produce) energy, or a component that is incapable of power gain. A component that is not passive is called an active component. An electronic circuit consisting entirely of passive components is called a passive circuit (and has the same properties as a passive component). Данное издание не является оригинальным.
