The evolution of sensor technology and Radio Frequency Identification (RFID) research makes easy integration of RFID data and sensing data into same RF tag, called sensor tag. The diverse RFID applications and services necessitate collection and manipulation of integrated RFID-sensing information at the same system. Systems deploying sensor tag can achieve both ID data and sensing data simultaneously. Various applications require generation of tag status reporting, sensing threshold alarms, controlling of tag modes and states, and extraction of sensing data from tag memory. However, existing standards proposed by EPCglobal and ISO are limited only to RFID data manipulation and lacks efficient management of sensor tags. Therefore, a...

Almost all the pumps increase the pressure energy of the liquid which is subsequently converted into potential energy as the liquid is lifted from a lower level to a higher level. Positive displacement pump is one of the categories of the pump. Positive displacement pump is also known as reciprocating pump on the basis of its operation. In general reciprocating pump a electric motor is used along with crank and connecting rod assembly to drive the reciprocating motion of the piston. When the crank gets rotating motion of from the motor the piston moves in backward and forward directionSolenoid or electromagnetic coil can be used as the driving source. Electromagnetic field created by the solenoid or electromagnetic coil can control the...

The area of WSN is one of the emerging and fast growing fields in the scientific world. This has brought about developing low cost, low-power and multi-function sensor nodes. However, the major fact that sensor nodes run out of energy quickly has been an issue and many energy efficient routing protocols have been proposed to solve this problem and preserve the longetivity of the network. This is the reason why routing techniques in WSN focus mainly on the accomplishment of power conservation. Most of the recent publications have shown so many protocols mainly designed to minimize energy consumption in sensor networks. This work proposes a hierarchical routing technique which shows energy efficiency. Our technique selects cluster head...

This book considers dense wireless sensor networks that are designed for applications with continuous data delivery models, where sensors periodically report to a base-station or a data processing center. Since wireless communication is considerably more energy-expensive than signal processing or computing, we tackle the problem using three different energy-conserving techniques: clustering, which improves the communication efficiency, node scheduling, which obviates wasteful data transmission and sensing, and distributed data compression, which reduces the wireless transmitted data volume. All the developed algorithms and protocols are distributed and localized, requiring no global knowledge, central control or request-and-acknowledge...

The capital cost of a typical BWR is of the order of 65 % of the total power cost, extracting more energy from an existing reactor or reducing the physical size of future BWRs may reduce total cost of nuclear power considerably. The large assembly concept is based on replacing four traditional BWR assemblies and large water gap regions with a single large assembly. Water rods within the assembly maintain the moderating power and accommodate finger type control rods. The new assembly design adopts smaller fuel pins and larger pitch to diameter ratio to allow for the margin to increase the core power density. The originality of the design mainly lies in the use of the dispersed finger-type control rods, which are much more effective...

India is the home to more than 500 flowering plants that can yield dyes. Though there is a large plant resource base, little has been exploited so far. “An Introduction to FLORAL DYES” provides a precise technical knowledge about some of these flowering plants along with the basic principles of extraction and application of the floral dye in Textile Industry and in Powder - Gulal Industry. These floral dyes are non toxic, non allergic to human skin, easily available and more economical. Some natural dye sources produce truly exquisite shades and are more economical to purchase than synthetic dyes. The process of extraction of dye is economically viable as the raw materials are available at low cost. This technology can be used in...

The greatest demand facing the automotive industry has been to provide safer vehicles with high fuel efficiency, at minimum cost. Current automotive vehicle structures have a fundamental handicap: a short crumple zone for crash energy absorption. An innovative inflatable bumper concept called the “I-bumper,” has been developed in this research to improve the crashworthiness and safety of military and commercial vehicles. The I-bumper has several active structural components, including a morphing mechanism, a movable bumper, two explosive airbags, front posts filled with granules, and a morphing lattice structure with a locking mechanism that provides desired rigidity and energy absorption capability during a crash. An analytical...

Coloured conducting textiles have shown a wide range of potential applications in heating fabrics, electromagnetic wave absorption, and wearable optoelectronic devices. This research aimed at clarifying some issues occurred in the research project on coloured conductive textiles. The investigation firstly clarified a possible chemical reaction that took place between a commercial dispersing dye (Terasil Red G) and the conducting polymer polypyrrole, through chemical separation, structural identification and spectrum characterisations. Then, a series of acidic dyes were introduced into polypyrrole matrix during the vapour coating of conducting polymer on the wool fabrics. Colour and thermal stability studies were conducted.

The aim of this research work is to develop a highly efficient process environment for the production of PET bottles. The ingenious process design carried out includes optimization of both the preheating stage of the process and PET preform shape. The heating of the PET preform is conducted using microwave. Dielectric properties of the PET preform, measured in this work, are used for designing microwave applicators. Studies into heat transfer were conducted by measuring temperature rise and temperature distribution during heating. A remarkable achievement is presented showing that PET preforms can be heated at least 5 times faster and more efficiently by microwave power. The results indicate that the designed cylindrical cavity works...

The product is more complicated and the parts can fit to the adjacent parts with multiple constraints for improving the stiffness and accuracy of the assembly. The average dimension of the parts may shifts or drifts from the nominal value during the manufacturing process. And, the dimension distribution of the parts can be in different non- normal distribution since they are manufactured by different manufacture process. This method predicts more accurate resultants by an interpolation method. With this method, the assembled state of an assembly with multiple constraints can be evaluated. The assembly behaves a higher probability of stiffness, as if the minimum gap index is smaller. For the mean shift studied for the cases represented in...

Turbulence exists in almost all real flow problems; and its modeling is one of the major concerns in modern aerodynamics and in many engineering flows. This project shares equally the features of aerodynamics as well as CFD and is about modeling of external compressible flow over a body (airfoil) using one of the turbulence modeling techniques (i.e. Spalart-Allmaras 1 Equation model) in CFD. The computational domain has been generated in 2D by the use of Gambit which is Fluent's geometry and mesh generation software. The generated mesh was then successfully exported to Fluent solver where the flow over the body (airfoil) was simulated using turbulence model Spalart-Allmaras (1-Eqn) for different angle of attacks and different Mach...

Well productivity is one of primary concerns in field development and provides the basis for field development strategy. The primary focus of this book is to derive productivity formulae for oil wells in anisotropic reservoirs using straightforward mathematical techniques. Pressure transient analysis methods presented in this book are based on analytical solutions of the various forms of flow equation. It is the authors' opinion that the distinct advantage of the analytical methods is in their simplicity and the ability to identify correctly the main physical features of a given system. The analytical approach should be considered as an initial and necessary step by which the system is identified and first estimates of parameters are...
