Temperature Rise Estimation of Induction Motor Drives Based on Loadability Curves to Facilitate Design of Electric Powertrains
2017
Thermal protection limits are equally important as mechanical specifications when designing electric drivetrains. However, properties of motor drives like mass/length of copper winding or heat dissipation factor are not available in producers’ catalogs. The lack of this essential data prevents the effective selection of drivetrain components and makes it necessary to consult critical design decisions with equipment's suppliers. Therefore, in this paper, the popular loadability curves that are available in catalogs become a basis to formulate a method that allows to estimate temperature rise of motor drives. The current technique allows for evaluating a temperature rise of a motor drive for …
Process support in MetaCASE: implementing the conceptual basis for enactable process models in MetaEdit+
2002
This study concerns the support of information system analysis and design process in a metaCASE environment. We see a process as highly, evolutionary and unstructural in nature, thus requiring the tailorability of user process models and their conceptual basis, process modelling language (PML). In addition to the flexibility needed for guiding various system developers, the CASE environment needs to be enacted using strictly defined environment actions. A distinction between user and environment processes is made, hence distinguishing also their conceptual basis and modelling requirements. The study depicts the realisation of the basic concepts and tools required in modelling a PML and the …
Exploring the generative power of performance measurement systems design
2019
Abstract Prior studies recognise the enabling power of incompleteness in the design of Performance Measurement Systems (PMS). We add to these studies by exploring the ‘time dimension’ of incompleteness as a way to delve into the generative power of design. To this aim, we rely upon the experience of a knowledge-intensive organization during the design of a new PMS. While knowledge complexity engaged the participants within an open-ended design process, incomplete measures were associated with unfolding memories of the past and confident beliefs in future solutions, which generated effects through the knowledge gaps that they entailed, as well as through the projections in the past and in th…
Thermo-mechanical analysis of irradiation swelling and design optimization of the IFMIF target assembly with bayonet backplate
2017
Abstract The availability of a high flux neutron source for testing candidate materials under irradiation conditions, which will be typically encountered in future fusion power reactors (ITER, DEMO, FPR), is a fundamental step towards the development of fusion energy. To this purpose, the International Fusion Materials Irradiation Facility (IFMIF) represents the reference option to provide the fusion community with a DEMO-relevant neutron source capable of irradiating samples at a damage rate of up to 20 dpa/fpy (in steel) in a volume of 0.5 l. In the framework of the engineering design activities of IFMIF, ENEA is committed in the design of the lithium target assembly (TA) with removable (…
Road Planning and Route Alignment Selection Criteria in the Norwegian Context
2019
This paper reveals the main factors that guide road alignment design process in Norway. The goal is to discover what constitutes the main priorities for road planners, how these priorities are ranked when it comes to alignment selection, and how they are related to guiding factors identified in official planning documents and government transport plans throughout the life cycle of a road. This is done through a comprehensive literature and data search, involving published academic research in the road alignment design field, and by exploring Norwegian road planning documents and guidelines. Examples from a recently implemented road project are also included as a way to illustrate alignment …
Behind the Scenes of Scenario-Based Training: Understanding Scenario Design and Requirements in High-Risk and Uncertain Environments
2017
Simulation exercises as a training tool for enhancing preparedness for emergency response are widely adopted in disaster management. This paper addresses current scenario design processes, proposes an alternative approach for simulation exercises and introduces a conceptual design of an adaptive scenario generator. Our work is based on a systematic literature review and observations made during TRIPLEX-2016 exercise in Farsund, Norway. The planning process and scenario selection of simulation exercises impact directly the effectiveness of intra- and interorganizational cooperation. However, collective learning goals are rarely addressed and most simulations are focused on institution-specif…
Designing an Online Escape Room as an Educational Tool
2021
In this chapter, online escape rooms are assessed as part of game-based learning (GBL) that can be used as a free educational tool for teachers to enrich their remote classes. This study was created to test the possibilities that an escape room can provide in a remote learning environment. The benefits and the downsides are explored to understand the design process and the results from the different mechanisms used. The results can give an insight into future possibilities for making escape rooms for classes or for using this format as a prototype for an escape room application. An online escape room for Latvia’s Independence Day was developed for this purpose based on flexible learning iti…
Analysis of User Needs for the Redesign of a Postural Seat System
2009
The identification and translation of customer needs early in the design process is a major challenge for product design researchers. Some needs are explicit and customers can state them very clearly. Other needs are implicit, so customers cannot express them, e.g., those pertaining to the affective and emotional sphere. In this work, we describe the methods most commonly used to capture explicit and emotional customer needs, and the traditional ways in which they are used. Moreover, an integration of QFD and Kansei engineering, a simplification of Kano methodology, and a new attribute weighing methodology based on the “choice time” are discussed for the design of an innovative postural sea…
Crowdboard: Augmenting in-person idea generation with real-time crowds
2017
Online crowds can help infuse creativity into the design process, but traditional strategies for leveraging them, such as large-scale ideation platforms, require time and organizational effort in order to obtain results. We propose a new method for crowd-based ideation that simplifies the process by having smaller crowds join in-person ideators during synchronous creative sessions. Our system Crowdboard allows online crowds to provide real-time creative input during early-stage design activities, such as brainstorming or concept mapping. The system enables in-person ideators to develop ideas on a physical or digital whiteboard which is augmented with real-time creative input from online par…
Explanatory frameworks for interaction design
2005
Explanatory design means the practice by which design solutions are evidence-based. This practice has been the norm in engineering design, relying as it does on the laws of science, but much less attention has been paid to the necessity of abandoning intuitive practices in designing for the human element within technological systems. One reason for this may have been the variety of explanatory bases within psychology. There is no single psychological framework for explaining human behaviour; instead different types of problems must be solved by using very different types of explanatory frameworks and theory language. Cognitive capacity, emotions and mental contents may serve as examples of …
