Towards formalised end-user participation in information systems development process
2006
Creating requirements specifications is one of the most challenging tasks in the systems development. For a complete specification, different kinds of information are gathered. This includes information about the domain and context specific technical issues, and about multifaceted cultural, political, communicational, motivational, and personal issues. As there is no information systems development (ISD) method that would yield such information comprehensively, it could be achieved by user-oriented approaches, for instance by participatory design (PD). Reciprocally, unfortunately those do not provide detailed instructions for the systems development. In this paper, we will present our exper…
The Facilitation of Design Students’ Spatial Perception in Study Process
2015
Spatial thinking is a considerable structural component of design students’ professional competence. Objective of the current study is to evaluate and promote spatial perception of students using in the learning process principles of universal design for learning (UDL). As the result a model for development of design students spatial perception has been developed and approbated.
Contributions Regarding the Application of the Six Sigma Method in Tourism as a Quality Engineering Method
2015
The problem of quality and customer orientation are the most important leverage in obtaining success. Over the time, the influence of human resources in terms of training, controlling and shaping client expectations has gained significant meanings. Research in this field has led to the formulation of the hypotheses according to which human resources can represent a vital element in obtaining a competitive advantage. In line with the importance of the topic addressed, the main objective of these scientific approach is to identify the current problems related to the quality of Romanian tourism services and to propose a improvement program using the six sigma method. The paper provides an exce…
Case study: developing campus spaces through co-creation
2016
ABSTRACTHigher education institutions are designed to support their core processes – learning, teaching, research, and societal impact. In order for university facilities to support these activities, it is crucial to determine together with the users what these activities are and how they are supposed to be developed in the future. This article examines the relationship between user needs and the service level in construction projects through a case study where a university cafeteria was renovated using a participatory design (PD) method called charrette. The aim of this case study was to study the effects of collaborative ways of working when applied to a space retrofit project, and how th…
Understanding flow experience from users’ requirements
2015
This paper argues that the concept of flow can be useful in gaining a better understanding of information system users’ flow experience. This paper applies this concept in the requirements development phase of an Internet protocol television e-learning service development project. The findings show that flow experience can be visualised and measured, and that there are differences in how users see and perceive different features. Some features are driven by more experiential needs, whereas others are driven by more task-oriented goals. The findings indicate that the users’ perceived flow experiences can already be measured during the early phases of information systems IS development projec…
Evaluation of the laboratory prediction of surface properties of bituminous mixtures
2009
Abstract An experimental and analytical investigation was carried out both in laboratory and in situ on wearing courses. The approach presented in this paper aims to predict the in situ density and surface properties of bituminous layers, during the phase of mix design in laboratory. Therefore, the main attempt of this study is to identify, amongst the commonly available laboratory equipments, the most adequate for producing specimens that, used for carrying out simple and reliable laboratory test, allow the prediction of the surface characteristics of the mixture as laid on site. This is done by comparing the data collected from an experimental site with those calculated from laboratory sp…
Mechanical construction and installation of the ATLAS tile calorimeter
2013
This paper summarises the mechanical construction andinstallation of the Tile Calorimeter for the ATLASexperiment at the Large Hadron Collider in CERN, Switzerland. The TileCalorimeter is a sampling calorimeter using scintillator as the sensitivedetector and steel as the absorber and covers the central region of the ATLASexperiment up to pseudorapidities ±1.7. The mechanical construction ofthe Tile Calorimeter occurred over a periodof about 10 years beginning in 1995 with the completionof the Technical Design Report and ending in 2006 with the installationof the final module in the ATLAS cavern. Duringthis period approximately 2600 metric tons of steel were transformedinto a laminated struc…
Engaging learners through virtual worlds
2010
Abstract The aim of this paper is to explore how virtual worlds could support the engagement for learning. This paper reviews the results of studies that utilized virtual worlds to engage learners. The results are examined in two levels, namely learning gains and design principles. It has been found out that deeper learner engagement results in higher learning gains. In some studies better content retention is also noted. Many studies also suggest design principles for using virtual worlds for facilitating engaged learning. This paper builds a framework for the design and use of virtual worlds in education for better learner engagement.
Performance of a pilot-scale biotrickling filter in controlling the volatile organic compound emissions in a furniture manufacturing facility.
2009
A 0.75-m3 pilot-scale biotrickling filter was run for over 1 yr in a Spanish furniture company to evaluate its performance in the removal of volatile organic compounds (VOCs) contained in the emission of two different paint spray booths. The first one was an open front booth used to manually paint furniture, and the second focus was an automatically operated closed booth operated to paint pieces of furniture. In both cases, the VOC emissions were very irregular, with rapid and extreme fluctuations. The pilot plant was operated at an empty bed residence time (EBRT) ranging from 10 to 40 sec, and good removal efficiencies of VOCs were usually obtained. When a buffering activated carbon prefil…
A dynamic channel access strategy for underlay cognitive radio networks: Markov modelling and performance evaluation
2015
Unlike in overlay cognitive radio networks, secondary users in underlay cognitive radio networks can access licensed spectrum even at the presence of a primary user, given that the interference caused by the secondary transmission is lower than a pre-specified threshold. Based on this underlay access principle, we propose in this paper a dynamic channel access strategy for multi-channel cognitive radio networks. Different from existing underlay access techniques, channel assembling, spectrum adaptation and restricted channel occupancy are also considered in the proposed strategy in order to achieve better performance in the secondary network. Accordingly, a partial channel occupancy mode, w…
