Analysis of the use of a workflow engine for OTRUM system software

2007

Masteroppgave i informasjons- og kommunikasjonsteknologi 2007 – Høgskolen i Agder, Grimstad Workflow engines are attracting more and more attention. Applications based on workflow engine technology are currently developed and deployed by many companies, such as OTRUM Company. In this project, we focus on the analysis and development of an efficient workflow engine for interactive TV. The research project will realize workflow engine solutions based on three choices including commercial workflow engine, open source workflow engine, and a workflow engine implemented from scratch. In this project, we go through all mentioned solutions. In the literature, many proposed workflow engines are invo…

Following the WCAG 2.0 techniques: Experiences from designing a WCAG 2.0 checking tool

2012

Published version of a chapter in the book: Computers Helping People with Special Needs. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-642-31522-0_63 This paper presents a conceptual analysis of how the Web Content Accessibility Guidelines (WCAG) 2.0 and its accompanying documents can be used as a basis for the implementation of an automatic checking tool and the definition of a web accessibility metric. There are two major issues that need to be resolved to derive valid and reliable conclusions from the output of individual tests. First, the relationship of Sufficient Techniques and Common Failures has to be taken into account. Second, the logical combination of the…

A BMA Analysis to Assess the Urbanization and Climate Change Impact on Urban Watershed Runoff

2016

Abstract A reliable planning of urban drainage systems aimed at the mitigation of flooding, should take into account the possible change over time of impervious cover in the urban watershed and of the climate features. The present study proposes a methodology to analyze the changing in runoff response for a urban watershed accounting several plausible future states of new urbanization and climate. To this aim, several models simulating the evolution scenario of impervious watershed area and of climate change were adopted. However, it is known that an evolution scenario represents only one of all possible occurrence and it is not necessary the true future state, therefore it is needed to fin…

Stochastic Learning-Based Estimation Methods for Pattern Recognition and Its Application to Topic Detection and Tracking

2008

Masteroppgave i informasjons- og kommunikasjonsteknologi 2008 – Universitetet i Agder, Grimstad Every Pattern Recognition (PR) problem involves a training and a testing phase. In the training phase, the system is presented with samples, using which the distribution (also called the classconditional distribution), of the features, is estimated. Traditional PR systems assume that the class-conditional distributions are stationary, and thus that they do not change with time. Recently Oommen and his co-authors have presented a strategy by which the parameters of a binomial/- multinomial distribution can be estimated when the distribution is non-stationary. In this thesis, we propose a selection…

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…

Analysis of Offshore Knuckle Boom Crane - Part Two: Motion Control

2013

In this paper design of electro-hydraulic motion control systems for offshore knuckle boom cranes is discussed. The influence of the control valve bandwidth along with the ramp time for the control signal are investigated both analytically with simplified system models and numerically with an experimentally verified crane model. The results of both types of investigations are related to general design rules for selection of control valves and ramp times and the relevance of these design rules is discussed. Generally, they are useful but may be too conservative for offshore knuckle boom cranes. However, as demonstrated in the paper, the only proper way to determine this is to evaluate the mo…

Democracy Squared: Designing On-Line Political Communities to Accommodate Conflicting Interests

2005

Published version of an article published in Scandinavian Journal of Information Systems, 17 (2), 133-168. Also available from the publisher at: http://aisel.aisnet.org/sjis/vol17/iss2/5. On-line political communities, such as the Norwegian site Demokratitorget (Democracy Square), are often designed according to a set of un-reflected assumptions about the political interests of their potential members. In political science, democracy is not taken as given in this way, but can be represented by different models which characterize different relationships between politicians and the citizens they represent. This paper uses quantitative and qualitative content analysis to analyze the communicat…

The Effect of the Perceived Utility of a Management Control System with a Broad Scope on the Use of Food Waste Information and on Financial and Non-F…

2020

The purpose of this study is to analyse the effect of the perceived utility of a management control system with a broad scope on the use of food waste information and on financial and non-financial performances in restaurants. To collect data, a questionnaire was administered in Brazilian restaurants. Data from 206 restaurants were analysed with structural equation modelling, which was performed with SmartPLS software. The results reveal that a management control system of broad scope, which includes non-financial information, is oriented towards the future, and contains an external and long-term focus, assists in the use of information on food waste. In addition, the use of information abo…

VERSO UN’ARCHITETTURA RESPONSABILE ED ADATTIVA

2022

L’intento è quello di analizzare le affinità e differenze che contribuiscono il passaggio concettuale per gestire la complessità del progetto tecnologico attraverso le sue realizzazioni di nuova concezione, che ad oggi dovranno esser ripensate nel loro atto realizzativo con le conseguenti ricadute responsabili verso l’ambiente ed il territorio. A tal proposito è risultato utile introdurre la “Direttiva Europea 85/384” con i suoi undici punti che delinea la figura dell’architetto. Il progettista dovrà esser una figura consapevole di un sapere trasversale fondato su ‘conoscenze’ e ‘capacità’ ormai dedite al risparmio delle risorse e lontano dalla velleità da palcoscenico. The intent is to ana…
