13. Effect of Log Length on Forestry Loading and Unloading
ABSTRACT This study aimed to technically evaluate loading and unloading with different wood lengths . Data used were obtained from log harvesting areas of a forestry company in southern Brazil, on operations with loblolly pine logs. The study addressed the analysis of time and motion, being divided into loading, unloading, mooring and unmooring. Four treatm

17. Offshore Energy Harvesting of a Marine Floating Pendulum Platform Model
Abstract This work presents an analysis of an ocean wave energy harvesting system. This system is composed of a direct current (DC) power generator attached at the middle-top of a floating platform. A pendulum is connected to the generator’s shaft. It is considered that the ocean waves motion swings the platform in the vertical direction, which transfers e

18. Equipartition of energy, Avogadro law and ratio of specific heats
Abstract The equipartition of energy in its simplest form, which is related to the translational motion of the molecules of a gas, was announced independently by Waterston in 1845 and by Clausius in 1857. In its more general form, it was formulated by Maxwell in 1860. Together with the relation between pressure and translational motion, given by the kinetic

19. Investigating Hyperbolic Shear Deformation Theory on vibroacoustic behavior of the infinite Functionally Graded thick plate
Abstract This paper applies acoustic analysis of Sound Transmission Loss (STL) through infinite Functionally Graded (FG) thick plate employing Hyperbolic Shear Deformation Theory (HSDT). The procedure for applying a FG plate is followed by considering the material properties are changed continually based on power-law distribution of the materials in terms of

20. Implementation Analysis of a Washout Filter on a Robotic Flight Simulator - a Case Study
ABSTRACT This paper presents a detailed analysis about the implementation of a washout filter on the SIVOR (Simulador de Voo Robótico - Robotic Flight Simulator) project. The main objective of this project is to develop, on an anthropomorphic robot, a flight simulator which can be used as an Engineering Development System (EDS) and a pilot training platform

21. Thermal Analysis of Satellite Libertad 2: a Guide to CubeSat Temperature Prediction
ABSTRACT: We present a model for predicting the temperature of three-unit CubeSat on a low Earth orbit, which supposes a single temperature common to all satellite components. Our exposition includes a detailed, to a large extent analytical, computation of the external heat fluxes for a particular orbit and spacecraft assumptions based on the features forese

22. Root canal preparation using micro-computed tomography analysis: a literature review
Abstract: This literature review has critically analyzed the published research related to the biomechanical preparation of root canals with three-dimensional analysis using micro-computed tomography (micro-CT). In December 2017, six databases (PubMed, Cochrane, Web of Science, Embase, Scopus, and Science Direct) were accessed using keywords to find articles

23. A New Buffer in Impact Reduction for Aerospace Applications
Abstract The aim of this paper is to introduce a new buffering mechanism in impact reduction during assembly process of two space vehicles. Probe-cone mechanism, due to its computational easiness, is employed to study impact interaction between multibody systems. The proposed buffer with a compact structure includes a probe equipped with axial and torsional

24. Diverging Relaxation Times of Domain Wall Motion Indicating Glassy Dynamics in Ferroelastics
Single crystals of PbZrO3 and LaAlO3 have been studied by Dynamic Mechanical Analysis measurements in the low frequency range f = 0.02-50 Hz. The complex Young's modulus exhibits a quite rich behavior and depends strongly on the direction of the applied dynamic force. The low frequency elastic response in the [110]c-direction is dominated by domain wall moti
