The Impact

Objective The study examines the integration of the Evidence-based Design (EBD) approach in healthcare architecture education in the context of an academic design studio. Background Previous research addressed the gap between scientific research and architectural practice and the lack of research on the use of the EBD approach in architectural education. Methods The research examines an undergraduate architectural studio to design a Maggie’s Centre for cancer care in Israel and evaluates the impact of the EBD approach on the design process and design outcomes. The research investigates the impact of the integration of three predesign tasks: (1) literature review of healing architecture research, (2) analysis and comparison of existing Maggie’s Centres, and (3) analysis of the context of the design project. Results The literature review of scientific research supported the conceptual design and development of the projects. The analysis of existing Maggie’s centers, which demonstrated the interpretation of the evidence by different architects, developed the students’ ability to evaluate EBD in practice critically, and the study of the projects’ local context led the students to define the relevance of the evidence to support their vision for the project. Conclusions The research demonstrates the advantages of practicing EBD at an early stage in healthcare architectural education to enhance awareness of the impact of architectural design on the users’ health and well-being and the potential to support creativity and innovative design. More studies in design studios are needed to assess the full impact of integrating EBD in architectural education.

Generalized Parameters

A three-dimensional motion simulation model of an open-loop kinematically constrained mechanical system is developed to simulate the motion response of a robotic arm to externally applied static loads. The general system consists of N rigid bodies connected together by (N-1) kinematic pairs. The class and type of kinematic pairs may be selected from a set of twelve physically realizable kinematic pairs. Six equations of force equilibrium are written for an ith body. A variational method is used to linearize these equations for incremental values of displacement and to incorporate the generalized parameters of the kinematic pairs and characteristics of the internal driving forces. Five applications of the proposed simulation model are discussed.

Spirit of science is one of the important components of science education theory. It not only directly affects the level of science education, but also indirectly affects the selection, education and evaluation of scientific researchers, and the development of science and technology in a country or region. Although more than a century ago, the researchers began to discuss the topic of spirit of science. However, to date, the research of the definition, attribute, structural model and its characteristics of the spirit of science has not yet made a breakthrough. Based on the detailed literature review, the related theoretical analysis and the research of the structural model of the spirit of science, this paper puts forward the new definition, the attribute and the establishment of the structural model of the spirit of science, and analyzes the match the situation from new structural model of the spirit of science and the scientific nature published by the American Society for the Advancement of Science. The results of this study are of great significance for raising the level of scientific education and cultivating future scientific researchers, enhancing their motivation and skills in innovation in scientific research and promoting the development of future scientific undertakings.

The latest methods in data acquisition provide engineers with stronger support than ever to make more informed decisions. Data acquisition is the process of making repetitive, timed measurements of multiple signal sources. The robotics team at the Oak Ridge National Laboratories builds a computerized model of robotic parts, such as robotic arm, and then runs a series of data acquisition tests on a prototype to determine how the arm will move. The robotic arm was constructed after engineers ran data acquisition tests on a prototype to learn how it would react to forces from the arm and from the human controlling the robot. Those results were considered when programming the robotic arm. Some companies use data acquisition methods to determine if it makes economic sense to implement a project. Data acquisition boards measure signals like friction, as measured here, and provide feedback that appears as numbers and wave measurements on the computer screen. Results can be downloaded to another software package, which displays the hard data as waves or graphs for analysis.

Abstract The objective of this paper is to design and model a translational robotic arm that is simple and cheap to manufacture while maintaining good functionality. Once the robotic arm is designed, the control analysis and computer simulation are conducted. When selecting the material used for the parts, the density and strength of are considered. This paper covers the design process, analysis and computer simulation of a robotic arm. The final design is a 4-DOF (degrees of freedom) pick and place robot. This robot has 1 prismatic joint and 3 revolute joints. The arm is designed to be used in multiple applications such as pick and place, car wash, chalkboard erasers, etc. Forward kinematics is used to calculate the end effectors position and orientation based on the positions of each joint. The Lagrange general method is used to come up with the equation of motion. Also, the control method selected for this robot was nonlinear decoupling PD control.

Key Players

This study investigates the roles of academic libraries in propagating Open Science. The study is a qualitative survey based on literature review. Various definitions of open science from different scholars and schools of thought were examined. Research articles on the effects of open science on research and the place of academic libraries in scientific research were reviewed. Open science enhances collaborations and sharing of resources among researchers. Metadata related activities are more prevalent due to open science. Open science has increased the relevance of science to our environment and world issues like privacy and the rightful author of scientific data are still some of the challenges facing open science. Academic libraries continue to take steps to be involved as key players in the propagation of open science through advocacy, building of institutional data repositories and serving as hubs for scientific collaboration among others. Academic libraries have to do more in the area of advocacy and provision of data repositories.
