Design and development of a six degree of freedom hand controller

The design objectives of a six degree of freedom manual controller are discussed with emphasis on a space environment. Details covered include problems associated with a zero-g environment, the need to accommodate both 'shirt sleeve' and space suited astronauts, the combination of both manipulator operation and spacecraft flight control in a single device, and to accommodate restraints in space. A variable configuration device designed as a development tool in which rotational axes can be moved relative to one another, is described and its limitations discussed. Two additional devices were developed for concept testing. Each device combines the need for good quality with its ability achieve a wide range of adjustments

Multi-axis manual controllers: A state-of-the-art report

A literature search was carried out to examine the feasibility of a six degree of freedom hand controller. Factors addressed included related areas, approaches to manual control, applications of manual controllers, and selected studies of the human neuromuscular system. Results are presented

EFFECTS OF SCAFFOLDING HIGHER ORDER THINKING QUESTIONS ON READER SELF-EFFICACY AND CRITICAL THINKING OF SIXTH GRADE STUDENTS

This study examined the potential benefits of instructional strategies that scaffold the development of higher order thinking (HOT) questions on reader self-efficacy and critical thinking. Another goal of this study aimed to investigate the relationship between reader self-efficacy and critical thinking. The explicit instruction of HOT questions involves four steps: (a) selecting Bloom’s revised taxonomy to identify effective question strands; (b) assessing HOT questions use through the Classroom Practice Record (CPR); (c) implementing strategy instruction focusing on explicit scaffolding techniques and allowing time to practice the implementation of strategies during assigned lessons for a period of eight weeks; and, (d) evaluating student self-efficacy, critical thinking, and HOT question use. Using a sample of convenience, this quantitative quasi-treatment design utilized 262 students at two different school sites belonging to the same District Reference Group (DRG). This study assessed the impact of instructional scaffolding of HOT questions in four classes among heterogeneously grouped students in sixth grade. Two teachers were trained in the instruction and implementation of the program. One school was assigned to receive the treatment of instructional scaffolding of HOT questions while the remaining school served as the comparison group. Several conclusions were drawn from the results. When teachers received explicit training in scaffolding HOT questions in the classroom, both students and teachers asked significantly more HOT questions than the comparison group. Results also point to a positive correlation between reader self-efficacy and critical thinking whereby students were more efficacious concerning their ability to read when they also demonstrate stronger critical thinking skills. Based on this study, it is recommended that scaffolding be explicitly used in the classroom to support effective learning. When teachers consciously and consistently apply scaffolding techniques, learning strategies become systematic. Furthermore, a questioning framework such as Bloom’s revised taxonomy provides an important framework that enables the learner and teacher to use verbs to actively identify diverse forms of thinking. The organization of thinking into six levels (remembering, understanding, applying, analyzing, evaluating, and creating) represented a pragmatic way to design higher order thinking tasks, coinciding with scaffolding techniques, to improve student learning

Six degree of freedom manual controls study report

The feasibility of using degree of freedom manual controls in space in an on orbit environment was determined. Several six degree of freedom controls were tested in a laboratory environment, and replica controls were used to control robot arms. The selection of six degrees of freedom as a design goal was based on the fact that six degrees are sufficient to define the location and orientation of a rigid body in space

Key environmental criteria associated with the invasion of Anguilla australis glass eels into estuaries of south-eastern Australia

Sampling for glass eels of the shortfinned eel, Anguilla australis, was conducted in a number of estuaries in south-eastern Australia using glass eel and stow nets during the winter and spring months of 1994 and 1995. Preliminary modelling of the invasion of A. australis glass eels was undertaken by determining correlations between Catch Per Unit Effort (CPUE) of glass eels and water temperature, electrical conductivity, lunar phase and height of high tide. Low (< 10000 µS/cm) electrical conductivity, medium (10-14°C) water temperature and high (>0m AHD) tide height showed significant correlation with high CPUE, but lunar phase (as moon age in days) did not. There appears to be some scope for predicting the invasion of A. australis glass eels into south-eastern Australian estuaries using temperature and electrical conductivity as key criteria for determining when glass eel fishing should commence. Such information is expected to contribute to the development of a commercial glass eel fishery in south-eastern Australia

Photometric and proper motion study of neglected open cluster NGC 2215

Optical UBVRI photometric measurements using the Faulkes Telescope North were taken in early 2011 and combined with 2MASS JHK$_s$ and WISE infrared photometry as well as UCAC4 proper motion data in order to estimate the main parameters of the galactic open cluster NGC 2215 of which large uncertainty exists in the current literature. Fitting a King model we estimate a core radius of 1.12$'\pm$0.04$'$ (0.24$\pm$0.01pc) and a limiting radius of $4.3'\pm$0.5$'$ (0.94$\pm$0.11pc) for the cluster. The results of isochrone fits indicates an age of $log(t)=8.85\pm0.10$ with a distance of $d=790\pm90$pc, a metallicity of $[Fe/H]=-0.40\pm0.10$ dex and a reddening of $E(B-V)=0.26\pm0.04$. A proportion of the work in this study was undertaken by Australian and Canadian upper secondary school students involved in the Space to Grow astronomy education project, and is the first scientific publication to have utilized our star cluster photometry curriculum materials.Comment: 10 pages, 9 Figures, 3 Table
