Energy storage media are matter that store some form of energy that can be drawn upon at a later time to perform some useful operation. A device that stores energy is sometimes called an accumulator. All forms of energy are either potential energy (eg. chemical, gravitational or electrical energy) or kinetic energy (eg. thermal energy). A wind up clock stores potential energy (in this case mechanical, in the spring tension), a battery stores readily convertible chemical energy to keep a clock chip in a computer running (electrically) even when the computer is turned off, and a hydroelectric dam stores power in a reservoir as gravitational potential energy. Ice storage tanks store ice (thermal energy)at night to meet peak demand for...

Recent advances in wireless sensor networks (WSNs) have led to many new protocols specifically designed for sensor networks where energy awareness is an essential consideration. Much attention has been given to the routing protocols since they might differ depending on the applications and network architectures. This proposed work, LEACH with Maximum Lifetime Routing, is based on the objective of maximizing the system lifetime. In this algorithm, clusters are formed randomly in each time period. Cluster heads transmit data to base station via multi-hop routing. By comparison with LEACH, LEACH with Maximum Lifetime Routing has better performance in time till first node dies and total dead nodes. Furthermore, nodes die in approximately...

Birds have long been known to use wind currents to fly long distances without flapping their wings. Due to technological advances, bird-sized aerial vehicles have now become practical. This book describes how such aircraft can extract the energy available in atmospheric turbulence. The principle of energy extraction is explained using simple gusts to illustrate the important concepts. Control algorithms are then developed to gain energy from realistic atmospheric turbulence. These theoretical studies are complemented by experimental validation using a dedicated autopilot and a small Unmanned Aerial Vehicle (UAV). Flight tests show that simple control laws can dramatically improve the performance of UAVs. This book summarizes a project...

Energetic neutral atom imaging, often described as "seeing with atoms", is a technology used to create global images of otherwise invisible phenomena in the magnetospheres of planets and at the boundary of the heliosphere - the far flung outer edge of the solar system. ENA images are constructed from the detection of energetic neutral atoms that are created in charge-exchange processes between ions in a hot plasma, such as the solar wind, and the atoms of a cold neutral background gas. Earth's magnetosphere preserves Earth's atmosphere and protects us from cell damaging radiation. This region of "space weather" is the site of geomagnetic storms that disrupt communications systems and pose radiation hazards to humans traveling at high...

Le secteur de l'energie en Belgique a constitue l'un des moteurs du developpement economique au XIXe siecle avec l'expansion des charbonnages qui ont contribue a l'industrialisation precoce du pays.

Workspace design plays an important role in ensuring workers safety and welfare. The issue is more pressing in the manufacturing industry, where many workers must remain in a standing position, assume awkward postures, and perform repetitive tasks for extended periods of time. In this research, an electromyographic measurement technique was used to measure muscle activity on four back muscles: the trapezius p. descendenz, the deltoideus p. scapularis, the infraspinatus, and the latissimus dorsi. The results showed a statistically significant (p 0.05) impact of left versus right side of the body, the degree of rotation to the right side of the body (0, 30 and 60 degrees rotation to the mid-saggital plane), BMI level: (normal weight: ( 25...

Droplet evaporation is important to health, climate, and the applications in drug delivery to the lungs, the engineering of nanostructures through spray drying, and the delivery of fuels for combustion. Valid simulation and computer code have been developed for multi-component droplet evaporation. Droplet size and surrounding gas temperature and pressure have been examined for the moving boundary coupled mass and heat transport problem. The code describes well the evolution of temperature, droplet size, and inhomogeneities with the temperature and compositions. Only one single crystal NaCl for each evaporating ethanol-water-NaCl droplet. Based on the simulation, various architectures such as hollow spheres, drug capsules,and high...

An engineer's degree is an advanced postgraduate academic degree in engineering that is conferred in Europe, Latin America and a few institutions in the United States. In Europe, the engineer degree is ranked at the same academic level as a master's degree, and is often known literally as an "engineer diploma" (abbreviated DI). In Latin America and the United States, the engineer's degree can be studied after the completion of a master's degree and is usually considered higher than the master's degree but below the doctorate.

Engineering ethics is the field of ? applied ethics which examines and sets standards for engineers' obligations to the ? public, their clients, employers and the profession. This article addresses the subject for both professional engineers and other engineers. Engineering does not have a single uniform system, or standard, of ethical conduct across the entire profession. Ethical approaches vary somewhat by discipline and jurisdiction, but are most influenced by whether the engineers are independently providing professional services to clients, or the public if employed in government service; or if they are employees of an enterprise creating products for sale. In the United States the first are usually ? licensed Professional...

The pass rate of engineering students has historically been low in tertiary institutions. This prompts the question: ‘Is the present engineering curriculum structure the most effective structure in which to prepare engineering graduates for work in the 21st century?' In order to investigate this question the current curriculum in tertiary institutions was examined. First, the philosophy of an engineering education was determined to establish what exactly an engineering education is. This philosophy was then used to determine which material is legitimate to include in an engineering curriculum and which material should be left out. Second, theories of teaching and learning were examined to determine whether the engineering curriculum is...

Current regulations in North America and Europe require engine manufacturers to develop an on-board real time misfire detection system to monitor emissions related systems in automobiles. These regulations create a challenge for the engine manufacturers to develop a low cost on-board real time system. In this book different techniques are presented to design such a system. The overall algorithm consists of two main steps. First, it employs a frequency domain pattern classifier to detect and identify the type of misfire pattern, and then it utilizes two different techniques to locate the misfire instances. The first technique for misfire instances detection is based on a weighted Wiener adaptive filtering technique, while the second...
