Motion design and visual communication in the era of ‘diffuse design’ paradigm. Analysis and evaluation of a didactic experiment

In recent years, co-creation and collaboration platforms to create and deliver new products and services have taken a step forward; this has led to the development of a new active involvement of users, who from co-designers have become independent designers, even if not experts. Co-design is dynamic and provides the tools to generate democratic design processes guided by the users themselves. The democratization of design tools is the premise for a new paradigm defined ‘Diffuse Design’ by Manzini (2015). This contribution explores the approaches of open design and open production with particular attention to the field of visual communication and the production of motion design artifacts. After an introduction to the co-design framework, the main open-production visual communication platforms are presented to offer an overview of the topic. Next, the potential of online platforms to enable non-designers to produce animated artifacts is explored by examining student projects in a motion design University course. The most significant outputs of the student experience are then described and critically analyzed. Finally, the conclusions investigate the different perspectives for reading the democratization of tools for creating visual artifacts and lay the foundations for future lines of research

Integrated support structure for GASCAN 2

The focus of the Worcester Polytechnic Institute (WPI) Advanced Space Design Program was the preliminary design of the Integrated Support Structure for GASCAN II, a Get Away Special canister donated by the MITRE Corporation. Two teams of three students each worked on the support structure. There was a structural design team and a thermal design team. The structure will carry three experiments also undergoing preliminary design this year, the mu-gravity Ignition Experiment, the Rotational Flow in Low Gravity Experiment, and the Ionospheric Properties and Propagation Experiment. The structural design team was responsible for the layout of the GASCAN and the preliminary design of the structure itself. They produced the physical interface specifications defining the baseline weights and volumes for the equipment and produced layout drawings of the system. The team produced static and modal finite element analysis of the structure using ANSYS. The thermal design team was responsible for the power and timing requirements of the payload and for the identification and preliminary analysis of potential thermal problems. The team produced the power, timing, and energy interface specifications and assisted in the development of the specification of the battery pack. The thermal parameters of each experiment were cataloged and the experiments were subjected to worst case heat transfer scenarios

Practical inference from industrial split-plot designs.

Many industrial response surface experiments are deliberately not conducted in a completely randomized fashion. This is because some of the factors investigated in the experiment are hard to change. The resulting experimental design then is of the split-plot type and the observations in the experiment are in many cases correlated. A proper analysis of the experimental data therefore is a mixed model analysis involving generalized least squares estimation. Many people, however, analyze the data as if the experiment was completely randomized, and estimate the model using ordinary least squares. The purpose of the present paper is to quantify the differences in conclusions reached from the two methods of analysis and to provide the reader with guidance for analyzing split-plot experiments in practice. The problem of choosing the number of degrees of freedom for significance tests in the mixed model analysis is discussed as well.Containment method; Data; Design; Experimental design; Factors; Fashion; Generalized least squares; Least-squares; Method of Kenward and Roger; Methods; Model; Ordinary least squares; Residual method; Satterthwaite's method; Split-plot experiment; Squares;

Teaching high frequency words to poor readers using flashcards : its effects on novel word acquisition, skill trasfer to in-text word reading, and passage reading competencies : a thesis in partial fulfillment of the requirements for the degree of Master of Educational Psychology, Massey University, Albany, New Zealand

Several literacy reports published in the last decade have emphasised the large gap in the reading attainment of children in New Zealand. A common barrier that prevents poor readers to catch up to their peers is difficulty in reading fluency, which is theorised to represent underlying difficulty in rapid and automatic word recognition. The ability to rapidly recognise a few common words, also known as high frequency words (HFWs), may increase the fluency of reading the majority of novel text. As such, the National Standards for literacy achievement outline the development of basic HFW vocabulary by the end of the first few years at school. However, past research that has investigated single word training has rarely used HFWs and those that have used HFWs have scarcely investigated its transfer to in-text reading. Therefore, the aims of the current research were to provide an investigation of HFW training and its influence on word reading accuracy, intext word reading, and passage reading accuracy, speed, and comprehension. Experiment 1 was a single case design carried out with one 8 year old participant and was largely used to inform the second experiment. Experiment 2 was a multiple baseline design carried out with five 8-9 year old participants using a modified training procedure. Experiment 1 utilised visual analysis and Cohen’s d effect size analysis whereas Experiment 2 also used statistical analysis, made possible through the Wampold-Worsham method of randomisation incorporated into the experimental design. The results of both experiments indicated that training facilitated word reading accuracy but the successful transfer of target words to in-text reading was only observed in Experiment 2. Post-training increases to passage reading accuracy, speed, and comprehension scores were not apparent in either experiment. The main contribution of the current research is its applicability to classroom practice. Another important contribution of the study to research practice is the rare application of the Wampold-Worsham method of randomisation

The Capillary Pumped Loop Flight Experiment (CAPL): A pathfinder for EOS

The CAPL shuttle flight experiment will provide microgravity verification of the prototype capillary pumped loop (CPL) thermal control system for EOS. The design of the experiment is discussed with particular emphasis on the new technology areas in ammonia two-phase reservior design and heat pipe heat exchanger development. The thermal and hydrodynamic analysis techniques and results are also presented, including pressure losses, fluid flow, and non-orbit heat rejection capability. CAPL experiment results will be presented after the flight, presently planned for 1993

Design and Statistical Analysis of Plant Protection Experiment

An Australian co-operation with the national agricultural research project Thailand. This short course is intended to cover aspects of experimental design, sampling and statistical analysis for researchers in Entomology and Plant Pathology. The basic principles of experimental design are the same for plant protection research as they are in other areas of research. Problems in plant protection arise from the variation of the data, the complexity of the systems and interactions with environmental factors. In many cases, standard designs are quite adequate

Preliminary design polymeric materials experiment

A typical Advanced Technology Laboratory mission flight plan was developed and used as a guideline for the identification of a number of experiment considerations. The experiment logistics beginning with sample preparation and ending with sample analysis are then overlaid on the mission in order to have a complete picture of the design requirements. The results of this preliminary design study fall into two categories. First specific preliminary designs of experiment hardware which is adaptable to a variety of mission requirements. Second, identification of those mission considerations which affect hardware design and will require further definition prior to final design. Finally, a program plan is presented which will provide the necessary experiment hardware in a realistic time period to match the planned shuttle flights. A bibliography of all material reviewed and consulted but not specifically referenced is provided
