This chapter deals with the position control of quadrotor unmanned aerial vehicle (UAV) when quadrotor’s linear velocity is unavailable. We propose a hierarchical tracking controller for quadrotor UAV. The proposed controller does not require measurements of linear velocity of quadrotor. A nonlinear filter that avoids the need for measurements of linear velocity has proposed such that a global stability result is obtained for the position tracking...

Looking back at the history of control engineering, one finds that technology and ideas combine themselves until they reach a successful result, over the timeline of several decades (Bernstein, 2002). It is such that before the computational advances during the so-called Information Age, a manifold of mathematical tools remained abstract and limited to theory. A recent trend has been observed in combining feedback control theory and applications with...

Drying is inherently a cross and multidisciplinary area because it requires optimal fusion of transport phenomena and materials science and the objective of drying is not only to supply heat and remove moisture from the material but to produce a dehydrated product of specific quality (Mujumdar, 2004)[1]. There are two main modes of drying used in the heat drying or pelletization processes; namely, direct and indirect modes. Each mode of drying has...

In many industrial engineering and other technological processes, it is crucial to characterise heat and mass transfer, for example to avoid thermo mechanical damages. Particularly, in the inlet region of internal pulsed flows, unsteady dynamic and thermal effects can present large amplitudes. These effects are mainly located in the wall region. This suggests the existence of intense unsteady stresses at the wall (shear, friction or thermal stresses)....

Powder injection molding (PIM) has been shown itself to be a successful shaping technique for producing complex-shaped ceramic, metal or cermet parts. The process starts with preparing a high solid loading suspension, where ceramic or metal powder is mixed with a thermoplastic material. At high temperature the suspension is fluid and can be injected into molds by applying a pressure. Inside the mold the suspension takes the shape of the mold and then...

This paper is intended to direct the attention of researchers and designers of multi-legged walking robots to the problem of force sensing for such vehicles. The use of force information enables such systems to achieve new mechanical properties, increases the reliability and functional capabilities of walking robots and simplifies many control algorithms.

Remote sensing is a technique for measuring, observing, or monitoring a process or object without physically touching the object under observation. The remote sensing instrumentation is not in contact with the object being observed, remote sensing allows - to measure a process without causing disturbance - to probe large volumes economically and rapidly, such as providing global measurements of aerosols, air pollution, agriculture, environmental impacts,...

Introductory Chapter: Conserving Biodiversity in Protected Areas The establishment of protected areas is extremely important in particular for endangered species and sensitive habitats and should be included as one of the key issues of sustainable development elsewhere. However, they need to be better located and actively managed to deal with problems of such as illegal logging, human settlements, unsustainable tourism, encroachment, and challenges...

Planet Earth is in the Milky Way Galaxy, the cloudy band of light that stretches clear across the night sky. How many galaxies are there in the universe? For years astronomers thought that the Milky Way was the universe. Now we know that there are billions of them. Gail Gibbons takes the reader on a journey light-years away.

Introductory Chapter: Introduction to Thermomechanics Problems Thermomechanics therefore describes a broad category of phenomena. It is a generalization of classical mechanical theory and thermodynamic theory. Currently, thermomechanical coupling is a fully formed issue. Basic dependences and differential equations have been formulated based on mechanical and thermodynamic laws. Numerous methods and algorithms for solving differential equations of thermomechanical...
