Friction stir consolidation of aluminum machining chips
2017
Friction stir consolidation (FSC) is a solid-phase manufacturing process that consolidates metal powder, chips, or scraps into solid blocks via severe plastic deformation and solid state welding. It has the potential to be a more economical and âgreenâ process to recycle metal waste. In this study, solid discs were made from AA6061 aluminum alloy machining chips by FSC. The progression of the process was revealed by analyzing the motion of the tool, consolidating force, power history, and macro/microstructure of discs produced from a series of partial consolidation experiments. A bowl-shaped recrystallized zone in the vertical cross-sections of the disc products was observed and conside…
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 (…
Il Rilievo MMS di tracciati autostradali
2009
Già da alcuni anni alcuni autori hanno messo in risalto come, anche in ambito autostradale, la geometria d’asse intesa come il complesso plano-altimetrico degli elementi di tracciato, eserciti un ruolo non marginale sulla condotta di guida dell’utente. Grazie alle metodologie di verifica della coerenza della linea d’asse di tracciato (Design Consistency), si accerta o meno che esista un’armonica correlazione tra parametri geometrici significativi e la velocità, di progetto od operativa, del tronco considerato. L’espressione grafica di tale correlazione è il cosiddetto diagramma delle velocità, dalla cui analisi, secondo criteri invero peculiari di infrastrutture viarie non autostradali, è p…
Narrative Definitions for Game Design
2010
Enhancing the benefits of learning games by utilizing narratives or narrative elements is not a new idea. Many existing learning games utilize more or less story structures, virtual worlds, and various characters as a part of a story. Computer game genres, such as adventure games and role-playing games, have received a lot of attention in the field of serious games by researchers and game developers. Hence, the potential of narratives for learning support is already clearly recognized. However, narratives have not yet offered unambiguous solutions to the design of learning games. For example, more often than not the use of embedded stories does not lead to a desired outcome that is an enter…
Conquer the Net: An educational computer game to learn the basic configuration of networking components
2009
Advanced networking equipment is relatively expensive and student access to it is usually limited to scheduled times at computer laboratories within the university premises. Hence, it is important to make the most effective use of the time assigned and minimize the time that students spend in activities which can be performed outside the laboratory sessions. Familiarizing with the basic configuration commands is one such activity. We have developed a computer game to allow students to learn these in a motivating and pleasant environment. This game has been designed so that rules are easily learned and both cooperative and competitive learning are promoted. © 2009 Wiley Periodicals, Inc. Com…
Simulation as a game design tool
2009
In this paper we suggest using gameplay simulations on a logical event level as a design tool already in the early stages of the development process. The approach is centred on abstracting all unnecessary details of the gameplay to produce a highly simplified model of the game system. Compared to other kinds of intermediate design representations, such as sketches and prototypes, the simulations can reveal problems and opportunities in the longer term dynamics of possible gameplay. As an example we describe an implementation of a simulation model for the game Tower Bloxx using a simulation software package called DisCo.
Process control in the development of game-based learning environments
2009
This paper examines the development process of digital game-based learning environments (GBLE), focusing on the process control. The aim is to explore the alternatives to process control in GBLE development and provide guidelines for planning and carrying out process control in GBLE projects. This study is a part of the research project Human-Centered Design of Game-Based Learning Environments. The overall aim of the project is to construct a multidisciplinary and user-driven process for the development of digital GBLEs. The study was conducted according to the principles of development research and action research. The action research cycles consisted of four game development projects. The…
Game Mechanics in the Design of a Collaborative 3D Serious Game
2014
Background. This article investigates the potential of utilizing game mechanics in designing 3-D serious games for Computer-Supported Collaborative Learning (CSCL) and attempt to produce new information about designing collaborative serious games. Aim. This article has two aims: first, to clarify how theoretical knowledge of collaborative learning was related to game design in previous studies; and, second, to design a collaborative serious game based on theoretical knowledge of collaborative learning and game design. Results. The reviewed studies revealed the potential of using collaborative games in education. However, they showed that collaborative learning games were typically designed …
A platform for the development and the validation of HW IP components starting from reference software specifications
2008
Abstract Signal processing algorithms become more and more efficient as a result of the developments of new standards. It is particularly true in the field video compression. However, at each improvement in efficiency and functionality, the complexity of the algorithms is also increasing. Textual specifications, that in the past were the original form of specifications, have been substituted by reference software which became the starting point of any design flow leading to implementation. Therefore, designing an embedded application has become equivalent to port a generic software on a, possibly heterogeneous, embedded platform. Such operation is getting more and more difficult because of …
Assessing Effects of eGovernment Initiatives Based on a Public Value Framework
2012
Published version of a chapter in the book: Electronic Government. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-642-33489-4_21 Assessing effects of eGovernment initiatives is considered an important but challenging endeavor. Assessments are, among other things, important to justify e-government investments. They are challenging because they are complex, often based on locally defined indicators, many times over-emphasizing financial effects, imprecise, faced with a number of contingencies and very seldom validated. Consequently, effect assessments can be seen as imprecise and difficult to compare across different initiatives. This paper addresses some of the challen…
