Dynamic Response of a Rigital Displacement Motor Operating with Various Displacement Strategies
2019
Digital displacement technology has the potential of revolutionizing the performance of hydraulic piston pumps and motors. Instead of connecting each cylinder chamber to high and low pressure in conjunction with the shaft position, two electrically-controlled on/off valves are connected to each chamber. This allows for individual cylinder chamber control. Variable displacement can be achieved by using different displacement strategies, like for example the full stroke, partial stroke, or sequential partial stroke displacement strategy. Each displacement strategy has its transient and steady-state characteristics. This paper provides a detailed simulation analysis of the transient and steady…
Surface Characteristics of Machined Polystyrene with 3D Printed Thermoplastic Tool
2020
An effort is made in this work to appraise the surface characteristics of machined expandable polystyrene (EPS) with a novel 3D printed thermoplastic acrylonitrile-butadiene-styrene (ABS) tool. Linear grooves on EPS were made on a vertical milling machine that was modified to conduct experiments in the laboratory. The tests were designed as per the Taguchi L9 based factorial design of experimentation while varying process parameters such as depth of cut, spindle speed, and feed rate. The machining responses dimensional accuracy and surface roughness of the machined grooves were studied. Furthermore, the surface topography of the machined specimens was considered to investigate the mechanism…
Experimental Research on the Cutting of Metal Materials by Electrical Discharge Machining with Contact Breaking with Metal Band as Transfer Object
2020
The scientific paper presents practical research carried out by a mixed team of Romanian researchers from universities and the business environment. The research consists in applying the process of cutting metallic materials through electrical discharge machining with contact breaking using a metal band as a transfer object. The research was implemented with the help of a specially designed installation in the laboratory and subsequently all the necessary steps were taken to obtain the patent for it. Various metallic materials were cut using this process, but first of all, high alloy steels. In the global research conducted by the authors, active experimental programs and classic experiment…
Lying Cheating Robots : Robots and Infidelity
2018
Love has been described as unpredictable, immeasurable and non-purchasable and as such, poses challenges for anyone in a relationship to both stay in love, and to not fall in love with someone else. Scientists are still discovering whether or not love follows any specific recipe. Outlooks, personality, sense of humor and talent may not perfectly guarantee an individual falls in love with another, and more importantly is able to sustain that relationship. This article portrays a futuristic scenario in which truly intelligent and emotional robots already exist. Here, the bi-directional love discussed in Lovotics is not simulated through engineering, but rather is genuine from the perspectives…
Me, My Bot and His Other (Robot) Woman? Keeping Your Robot Satisfied in the Age of Artificial Emotion
2018
With a backdrop of action and science fiction movie horrors of the dystopian relationship between humans and robots, surprisingly to date-with the exception of ethical discussions-the relationship aspect of humans and sex robots has seemed relatively unproblematic. The attraction to sex robots perhaps is the promise of unproblematic affectionate and sexual interactions, without the need to consider the other&rsquo
Strategies of Identification of a Base-Isolated Hospital Building by Coupled Quasi-Static and Snap-Back Tests
2020
In this paper, the description of a series of quasi-static pushing tests and dynamic snap-back tests is proposed, involving the base-isolated emergency building of the Palermo university hospital. The base isolation system is characterized by a set of double-curved friction pendulum isolators placed on the top of the columns of the underground level, characteristics that cannot be found in the experimental studies available in the literature. The aim of the work was to investigate the static and dynamic properties of the building in question and comparing the in-situ results with the characteristics assigned during the design process and to assess the level of agreement. Static lateral push…
Calidad de vida laboral y autocuidado en enfermeras asistenciales con alta demanda emocional
2019
Resumen Objetivo Explorar las variables relacionadas con la calidad de vida laboral y el autocuidado de profesionales de enfermeria en situaciones estresantes y con alta demanda emocional. Metodo Cualitativo, segun el paradigma constructivista, combinando el metodo fenomenologico-hermeneutico/interpretativo mediante el uso de entrevistas semiestructuradas. La informacion fue analizada con Maxqda 11. Las entrevistas se realizaron a profesionales de centros sanitarios y servicios de Valencia con perfiles caracteristicos de enfermeria en unidades medico-quirurgicas, urgencias, oncologia, atencion domiciliaria, y de ayuda humanitaria. Resultados Los factores organizativos se expresaron como bar…
Presentación de las tareas, satisfacción de las necesidades psicológicas básicas y bienestar en atletas universitarios
2017
Basado en la teoria de las necesidades psicologicas basicas, se puso a prueba un modelo en el cual la presentacion de las tareas realizada por el entrenador predice la satisfaccion de las necesidades psicologicas basicas y el bienestar psicologico en los atletas universitarios. La muestra estuvo compuesta por un total de 468 deportistas (302 hombres y 166 mujeres), con edades comprendidas entre los 17 y los 28 a˜nos (M = 19.2; DT = 1.89), que cumplimentaron los instrumentos que evaluaban las variables del estudio. Los resultados del analisis de ecuaciones estructurales informaron que la presentacion de las tareas actuo como predictor positivo de la satisfaccion de las 3 necesidades psicolog…

Motivo de abandono del tratamiento desde la perspectiva del paciente con un trastorno de la conducta alimentaria
2016
Los tratamientos psicológicos y farmacológicos para los trastornos de la conducta alimentaria comportan costes personales y sanitarios. En este trabajo estudiamos los diferentes motivos que pueden estar asociados al abandono en ambos tipos de tratamientos en pacientes diagnosticados con un trastorno de la conducta alimentaria, así como el tipo de abandono: abandono tras evaluar, abandono precoz y tardío. Por otro lado, analizamos si existe alguna relación entre el diagnóstico y el tipo de abandono. Se examinaron diversas características (edad, sexo, diagnóstico, motivos y tipos de abandono, y satisfacción respecto a la unidad de trastornos de la conducta alimentaria) en 212 pacientes atendi…
