Design for Assembly (DFA) analysis and application for cold-gas thrusters of a space re-entry vehicle module
Design for Assembly (DFA) is a way of analyzing and designing, or redesigning, a product from the perspective of assembly in order to reduce cost and increase reliability and quality. A review was performed on the design of cold-gas thrusters of a space re-entry vehicle module project from MIT …

Selection and evaluation of joint types and joining processes for concurrent assembly/disassembly-based design
In designing products, Design-for-Assembly (DFA) has been successfully used for several decades to reduce lead times, processing times, and equipment overhead. Though the DFA approach results in products which are easy and efficient to assemble, such products may be difficult to disassemble and/or …

Energy harvesting-aware design of wireless networks
… access (TDMA), framed-ALOHA (FA) and dynamic-FA (DFA) are investigated in the presence of EH-capable devices. A new ALOHA-based MAC protocol tailored to EH-networks, referred to as energy group-DFA (EG-DFA), is then proposed. In EG-DFA nodes with similar energy availability are grouped together …

The Efficacy of Using Color In Sub-Threshold Vibration to Improve Older Adult Balance
… predictability(Sample Entropy), and complexity(DFA) were extracted for each of the sway trials. The statistical analysis was done using Python 3. First, ANOVA was used to determine the statistical significance of the baseline measures (entropy, DFA, and RMS) across the participants. Then a …

DESIGN FOR ASSEMBLY AND SCHEDULE OPTIMIZATION FOR LARGE STRUCTURE CONSTRUCTION
… construction efficiency: Design for Assembly (DFA) and schedule optimization. To improve assembly efficiency of smaller products, DFA methodologies have been widely developed and applied. The basis of these methods is to reduce the number of parts in the assembly and to provide a quantitative …

Efficiency measurement. A methodological comparison of parametric and non-parametric approaches.
… techniques are considered which are SFA, DFA, DEA-CCR, DEA-BCC and DEA-RAM. These techniques are then used on an artificially generated panel dataset using a two-input two-output production function framework based on characteristics of German life-insurers. The key contribution of the …

Quantum Chemistry Meets Machine Learning: Autonomous Computational Workflow for Chemical Discovery
… multiple density functional approximations (DFAs) to discover robust (i.e., DFA- insensitive) candidate compounds, which are in much better agreement with experimentally observed leads. Lastly, we built a DFA recommender that selects the DFA with the lowest expected error to the reference in …

Epigenetic modelling: DNA methylation and working towards model parameterisation
… We present a Deterministic Finite Automata (DFA) model for the DNA methylation mechanism controlled by DNA methyltransferase (DNMT) enzymes. This thesis provides a brief introduction to epigenetics, a survey of ongoing research on computational epigenetics and a description of the DNA …

Job satisfaction of Missouri high school principals as measured by the Minnesota satisfaction questionnaire
… job status. A discriminant functional analysis (DFA) was conducted to determine the extent the variables play a role in explaining the level of satisfaction of principals in the study. The findings of this study indicate that high school principals in Missouri are generally satisfied with their …

New Developments in Analytical Toxicology for the Investigation of Drug Facilitated Crime
Drug facilitated assault (DFA) is an increasing problem in the UK. The crime often occurs through the surreptitious administration of a drug into a victims drink, rendering the victim unable to resist the assault. The detection of these drugs in a biological specimen from the victim is one of the …
