This paper investigates the joint transmitter and receiver optimization for the energy efficiency (EE) in orthogonal frequency-division multiple-access (OFDMA) systems. We first establish a holistic power dissipation ...

This work presents the mathematical description, simulation and results for a dynamic analysis of a robotic arm with two degrees of freedom, one revolutionary and one a prismatic. The revolute link was considered with an ...

The necessity to reduce the weight of transport structures, such as cars and airplanes, has become more important due to gas emission regulations. In this regard, the use of hybrid structures made of steel and aluminum is ...

A model for the joint economic design of X̄ and R control charts is developed. This model assumes that the process is subject to two assignable causes. One assignable cause shifts the process mean; the other shifts the ...

This chapter presents a new methodology through a harmonic balance method to identify the parameters to describe the hysteresis effect in bolted joints using the Bouc-Wen model. The main idea is to adopt a priori smoothing ...
