HULLFORM & HYDRODYNAMIC CONSIDERATIONS IN THE DESIGN OF THE UK FUTURE AIRCRAFT CARRIER (CVF)

An overview is provided of the manner in which hydrodynamic and hullform-related design considerations were addressed in the development of the BAE SYSTEMS team’s design proposal for the UK Future Aircraft Carrier (CVF). It also outlines how broader design considerations such as aviation, survivability and supportability requirements influenced these aspects of the design. A summary is also provided of some of the more detailed requirements development, option assessment and performance evaluation work that has been undertaken. The aircraft carrier designs discussed in this paper correspond to the BAE SYSTEMS team’s final design submission as it stood in January 2003, at the time it was discontinued by the UK Ministry of Defence, in favour of the rival Thales / BMT team design that has since been developed into the UK Royal Navy’s new ‘Queen Elizabeth’ class aircraft carrier. This final BAE SYSTEMS design submission consisted of two distinct design variants - one configured to operate a CTOL-based air group, the other configured to accommodate a STOVL air group. Both variants were based on a common ‘core’ ship design. The discussion presented in this paper is applicable to both variants.

Optimistic locating method of transformer voiceprint based on beam and delay algorithm

In view of the on-line inspection mode of transformer voiceprint information during operation, an optimistic location method is proposed to assist the acoustic print diagnosis for fault identification, location and further evaluation work. Firstly, according to the directional location algorithm of antenna array (Beamforming), traditional directional location is extended to general spatial location. Then on the basis of TDOA(Time Difference Of Arrival) algorithm of time domain signal characteristic analysis, integrated weighted processing and data centralization, on the one hand, reduce the edge value, on the other hand, correct the trend of bad data, and improve the existing cross-correlation operation. The simulation results show that the optimized beam-based and weighted TDOA algorithm has excellent performance in 2D localization of transformer voiceprint. These research results can provide a basis for transformer online monitoring and voice print diagnosis.

A possible revival of population-representing digital human manikins in static work situations –exemplified through an evaluation of a prototype console for robotic surgery

BACKGROUND: In the 90s, digital human manikins (DHMs) were introduced in planning of workstations, by static or semi-static simulations. Modern DHMs can simulate dynamic work and offer a rapid way for a virtual pre-production ergonomic evaluation. Work-related musculoskeletal disorders may affect surgical performance and patient safety. A prototype of an open console, which is contrary to the conventional closed consoles and may be seen as a representative for a new generation, has been designed to reduce workload for robotic surgery surgeons. OBJECTIVE: The aim of this project was to test a new DHM tool with improved usability to evaluate the ergonomics of console of a robotic surgical system in a pre-production stage. METHODS: The DHM tool IMMA was used together with a 3D model of the prototype console. Twelve manikins who represented females and males from two national populations were introduced. Manikin-console distances, after console adjustments per manikin, were compared with a US checklist and Swedish standards for VDU work. RESULTS: The DHM tool was useful for this case, but the distances of the checklist and the standards were needed to be obtained “manually”. The automatic functions of the DHM worked smoothly but were not optimized for VDU work. The prototype fulfilled most, but not all, of the ergonomic criteria of the checklist and the standards. CONCLUSIONS: There is room for improvements of the adjustable ranges of the console prototype. DHMs may facilitate rapid pre-production evaluation of workstations for static work; if ergonomic assessment models for VDU work are built-in, there may be a revival of DHMs in static work situations.

Five ways to get a grip on the drawbacks of logic models in program evaluation

Logic models are perhaps the most widely used tools in program evaluation work. They provide reasonably straightforward, visual illustrations of plausible links between program activities and outcomes. Consequently, they are employed frequently in stakeholder engagement, communication, and evaluation project planning. However, their relative simplicity comes with multiple drawbacks that can compromise the integrity of evaluation studies. In this Black Ice article, we outline key considerations and provide practical strategies that can help those engaged in evaluation work to identify and mitigate the limitations of logic models.

DORA in practice

Although the San Fransisco Declaration of Research Assessment (DORA) provides guidelines for best practice in research assessment, many institutions and reviewers at first find it difficult to ensure that the guidelines are adopted in their own evaluation committees and evaluation work. In this talk, I will share some suggestions for how institutions can ensure that the DORA guidelines are used by their evaluation committees. Based on personal experience as a chair of review panel for organizations that have signed the DORA declaration, I will also share some experiences on how one as chair may facilitate the use of the DORA best practice in evaluation work, as well as how this influences the evaluation process.

Clarifying realist analytic and interdisciplinary consensus processes in a complex health intervention: A worked example of Judgemental Rationality in action

Judgemental rationality is infrequently referenced within discussions of Realist Evaluations. Judgemental rationality refers to researchers’ capacity to assess which, potential, meanings provide the most credible explanations. In evaluation work, rationale for analysis is provided, though rarely do we see how an evaluator made judgements between competing theories, and which theories were discarded and why. We provide a worked example of the application of judgemental rationality. The Engager intervention offered support to prison leavers with common mental health problems. The data for 24, purposively sampled, participants from the intervention arm of the trial were integrated. Bhaskar’s DREIC, a five-step analytical procedure, was used to transfactually theorise and interrogate the inferences made within, and across, cases. The findings demonstrated that the intervention was more effective when practitioners developed an in-depth understanding of the participant. We recommend that intervention developers look for ways to enhance therapeutic competencies and judgemental rationality in practitioner teams.

Deradicalization Programs: Recommendations for Policy and Practice

Involvement in violent extremism is not a one-way street. People can, and do, leave violent extremist movements. Understanding how and why they leave (or want to leave) constitutes actionable knowledge that brings immense practical benefits. Such knowledge may help in designing initiatives aimed at persuading people to leave violent extremist groups as well as reducing the risk of re-engagement in violent extremism in the future. Deradicalization programs have much to offer but they are not a magic solution to a highly complex, fluid problem. Not everyone who engages in violent extremism is necessarily going to benefit from such interventions, and no program can ever expect to produce complete success. Yet, they continue to show promise. Deradicalization programs can be effective for some and, if subjected to greater evaluation efforts, may prove far more beneficial than is currently believed. Despite an abundance (and apparent increase) in programming, a continued lack of evaluation work both fuels skepticism and hinders our ability to believe that there is a strong future for these programs.

WA Notify: the planning and implementation of a Bluetooth exposure notification tool for COVID-19 pandemic response in Washington State

Bluetooth exposure notification tools for mobile phones have emerged as one way to support public health contact tracing and mitigate the spread of COVID-19. Many states have launched their own versions of these tools. Washington State's exposure notification tool, WA Notify, became available on November 30, 2020, following a one-month Seattle campus pilot at the University of Washington. By the end of April 2021, 25% of the state's population had activated WA Notify, one of the highest adoption rates in the country. Washington State's formation of an Exposure Notification Advisory Committee, early pilot testing, and use of the EN Express system framework were all important factors in its adoption. Continuous monitoring and willingness to make early adjustments such as switching to automated texting of verification codes have also been important for improving the tool’s value. Evaluation work is ongoing to determine and quantify WA Notify’s effectiveness, timeliness, and accessibility.

New method for summative evaluation of UML class diagrams based on graph similarities

This paper deals with the problem of the evaluation of the student's productions during the construction of a UML class diagram from textual speciations, which can be a tedious task for teachers. The main objective is to propose a method of summative and semi-automatic evaluation of the class diagrams produced by the students, in order to provide an educational reaction on the learning process, and to reduce the evaluation work for the teachers. To achieve this objective, we must analyze these productions and study the transformation, matching, similarity measurement and comparison of several UML graphs. From this study, we adopted a method based on the comparison and matching of the components of several UML diagrams. This proposal is applied to evaluate UML class diagrams and focuses on the structural and semantic aspects of the UML graph produced by students compared to several solutions proposed by the teacher.
