True Signal

In any electrical or electronic systems, unwanted signals known as noise signals are encountered which interact with the true signal and thus affecting signal quality. Noise may enter into a device or system in many forms and have a different order of impacts. Prevention and elimination of noise had attained paramount importance to ensure signal fidelity. This chapter presents a comprehensive analysis on elimination of noise by electronic grounding of instrumentation and automation systems as well as various engineering considerations for the same.

Structural damage detection by the Holder exponent receives much attention recently. Many investigations have been successfully applied to the crack identification, especially for the beam-type structures. However, a comprehensive analysis of the Holder exponent has been absent. Result in some conclusions had been drawn are unilateral. In this paper, the mode shapes of the clamped-clamped beams are analytical studied and a program calculating the Holder exponents of the mode shape signals with different damages is compiled with MATLAB. By comprehensively studying the Holder exponents of the clamped-clamped beams with cracks of different sizes, locations, and different order modes, a new phenomenon that the values of the Holder exponent vary with different locations of the crack is detected. The results also show that the Holder exponent decreases with the increase of the mode number. However, there are not obvious relations between the Holder exponent and the order of the mode for the whole beam locations.

This article explores the spatial dynamics of agrofuels. Building on categories from the field of critical spatial theory, it shows how these categories enable a comprehensive analysis of the spatial dynamics of agrofuels that links the macro-structures of the global political economy to concrete, place-based struggles. Four core socio-spatial dynamics of agrofuel politics are highlighted and applied to empirical findings: territorialization, the financial sector as a new scale of regulation, place-based struggles and transnational spaces of resources and capital flows.
