Modeling and Backstepping Control of the Electronic Throttle System
2013
Published version of an article in the journal: Mathematical Problems in Engineering. Also available from the publisher at: http://dx.doi.org/10.1155/2013/871674 Open access Electronic throttle is widely used in modern automotive engines. An electronic throttle system regulates the throttle plate angle by using a DC servo motor to adjust the inlet airflow rate of an internal combustion engine. Its application leads to improvements in vehicle drivability, fuel economy, and emissions. In this paper, by taking into account the dynamical behavior of the electronic throttle, the mechanism model is first built, and then the mechanism model is transformed into the state-space model. Based on the s…
Conception de documents numériques : Parcours méthodologique
2009
There is a strong social demand for studies of digital document. Yet our models of society and education are struggling to integrate issues related to these types of documents. However, the subject is less than half a century old, and so it is hardly surprising that the writing and training practices are just being developed. Like the book, the digital document involves many different skills and techniques in its development. The list of jobs tends to grow steadily: ergonomists, referencing specialists, information architects, programmers, designers, integrators ... It is therefore difficult to have a global view on all this know-how and the related methodologies. This special edition seeks…
Stormwater Source Control as a Strategy for Sustainable Development: State of the Practice and Perceived Trends
2005
The primary objective of the paper is to draw upon the experiences acquired in many parts of the world to provide an up-to-date summary of the state of the practice for source control techniques and approaches, in a sustainable development context. After a discussion of the prevailing context for urban drainage approaches, three main themes covering techniques and design criteria, institutional aspects and performance issues are discussed relative to source control implementation. The discussion is based on findings from the compilation and analysis of available literature, recently developed databases, the experience of the different members of the SOCOMA group and recent research on desig…
Onnistuminen muotoilussa : muotoilijan työn tavoitteiden mittaus ja arviointi
2016
Muotoilun arvoa on mitattu yleensä lopputulosta ja ulkoisia hyötyjä arvioiden. Se, miten muotoilija itse määrittelee työnsä tavoitteet, on jäänyt vähäisemmälle huomiolle. Tässä tutkielmassa esitetään mittauskehikko muotoilijoiden omalle työlleen asettamien tavoitteiden mittaamista, kuvailua, vertailua ja toimialan kehityksen seurantaa varten. Mitattavan ilmiön hypoteesi käsittää seitsemän ulottuvuutta: kolme ekologisen kestävyyden periaatetta ja yhden sosiaalisen kestävyyden periaatteen sekä loppukäyttäjän tarpeet, muotoilijan omat tarpeet ja ulkoiset vaatimukset. Tutkielman alussa kuvaillaan muotoilualaa ja sen muutoksia Suomessa sekä arvojen merkitystä muotoilijan työssä. Teorialuku jäsen…
Parallel Genetic Solution for Multiobjective MDO
1997
Publisher Summary This chapter reviews a multiobjective, multidisciplinary design optimization of two-dimensional airfoil designs. The control points on leading and trailing edges remain fixed, and the y-coordinates of the other control points are allowed to change during the optimization process. The grid for the Euler solver depends continuously and smoothly on the design parameters. The number of nodes and elements in the mesh might vary according to design because the meshes for the Helmholtz solver are done using the local fitting. The computations are made on an IBM SP2 parallel computer using high-performance switch and the MPICH message-passing library. As gradients are not required…
Positive Computing as Paradigm to Overcome Barriers to Global Co-authoring of Open Educational Resources
2018
The adoption of Open Educational Resources (OER) can support collaboration and knowledge sharing. One of the main areas of the usage OER is the internationalization, i.e., the use in a global context. However, the globally distributed co-creation of digital materials is still low. Therefore, we identify essential barriers, in particular for co-authoring of OER in global environments. We use a design science research method to introduce a barrier framework for co-authoring OER in global settings and propose a wellbeing-based system design constructed from the barrier framework for OER co-authoring tool. We describe how positive computing concepts can be used to overcome barriers, emphasizing…
Strategic Design Towards Platform Collaboration in The Newspaper Industry: A Design Science Research Study
2020
The newspaper industry is challenged by unsustainable business models. To stabilize dwindling revenue streams, publishers opted for digital subscriptions as one avenue for generating additional revenue streams. Large publishers have indeed benefited from rising subscription numbers. However, smaller publishers are challenged to achieve the same results. Some of the root causes are high churn rates, adoption costs and lock-in effects of subscription services. News aggregator platforms may promise newspaper publishers a large pool of paying readers. But platform fees and the loss of direct customer relationships enact commercial barriers among publishers. This study proposes design science re…
Design time, run time, and artificial intelligence techniques for mobility of user interface
2011
Abstract Advancement in technology provides opportunities to user as well as challenges for application development organization. User interfaces which were design for specific device tend to be developed for various devices. Users are busy people, when they move among different context would like to move application with them. The current trend of users demanding mobile graphic user interface to support their daily life and work has led to a new generation of techniques. Design time technique provides better usability as compare to run time technique. On the other hand artificial intelligence technique like agent provides better flexibility and usability as compare to others. In this paper…
Continuous Requirements Risk Profiling in Information Systems Development
2015
With the increasing adoption of agile, lean, and iterative development methods, information systems development (ISD) has become continuous, meaning that system development moves rapidly from release to release. This means that work practices and challenges that practitioners face have changed. Despite these changes, requirements development is still critical in ISD. However, IS literature is silent on how to manage requirements-related risks in the practice of continuous IS development. To fill this gap, we propose a continuous requirements risk profiling method. The study is informed by design science research methodology, and we apply focus group interviews and a Delphi study for data co…
Consumers’ adoption of information services
2013
This paper reports on a design science research study that seeks to investigate how information service components affect consumers’ potential adoption of such services. More specifically, the paper develops a conceptual model that uses the theory of organizational information services (TOIS) and the unified theory of acceptance and use of technology (UTAUT) as a basis. The results indicate that individual constructs can be linked to service components. In turn, this result can potentially be instrumental in progress toward a deeper understanding of consumers’ adoption of information services and how this affects the development of such services and systems that support them.
