Evaluation Framework for Analyzing the Applicability of Criteria Lists for the Selection of Requirements Management Tools Supporting Distributed Coll…
2016
Effective requirements management and enabling tools are critical for successfully developing and maintaining services and products. The identification and selection of an appropriate requirements management tool can be a costly, time-consuming, and error-prone undertaking especially in the context of software product line requirements management, requiring the tools to support both product and platform development activities that often involve geographically distributed, collaborating, and competing stakeholders. Criteria lists have been developed to facilitate the selection. This research (1) creates an evaluation framework to review the applicability of the lists for the selection of req…
The Software Crisis of Synthetic Biology
2016
In fifteen years, Synthetic Biology (SB) has moved from proof-of-concept designs to several flagship achievements. Standardisation efforts are still under way, basic engineering concepts such as modularity and orthogonality are still controversial in biology, and making predictions from computer models is still unreliable. A deep characterization in the pattern of re-use of biological blocks in SB has not been attempted to date. We have compared the topological organisation of two different technological networks, one associated to a standard, large-scale software repository and the second provided by the Registry of Standard Biological Parts (RSBP). Our results strongly suggest that softwa…
Control systems for indoor lighting and computer simulation: analysis and comparison between software packages capabilities and results on a real cas…
2018
In the last years, computer capabilities have evolved rapidly and also the way to simulate building physics phenomena is changed and more developed. Each simulation software is developed with a less or more similar aim, using different algorithms and models and being used by people with different profile: specialist, architects, engineers, installers, etc. This paper deals with the analysis of capability of some of the most utilised software used to predict indoor lighting, including natural daylight contribution and assessment of energy consumption and savings related to specific design options. Furthermore, two of the analysed software have been tested simulating a case studying. Results …

The public procurement of information systems: dialectics in requirements specification
2017
When acquiring information systems, public entities face a dilemma. On the one hand, they want to procure the system that best suits their needs, which often requires lengthy dialogues with vendors. At the same time, they are restricted by government regulations that mandate limited dialogue in the interests of transparency and equal opportunities for all vendors. To examine how public entities deal with this, we followed three procurement projects in Norway. We show that this dilemma manifests itself as a dialectic between the thesis of getting the system requirements right and the antithesis of strictly adhering to regulations. Public entities search for a resolution of this dialectic thr…
Designing meeting support systems in a user-centered manner
1995
Multilateral diplomacy faces pressures to improve the efficiency of its operations. Because meetings play a central role in diplomacy they form one promising target in productivity improvements. Diplomatic meetings are rife with political maneuvering and embedded with pervasive diplomatic rituals and protocols which all affect considerably the content and form of successful technology interventions. In this paper we describe a meeting support system called the Helsinki Prototype System. To our knowledge it was the first meeting support system (MSS) which was intended to support multilateral diplomatic meetings. It was designed for the fourth Follow-up meeting of the Conference on Security a…
Problems in the interplay of development and IT operations in system development projects: A Delphi study of Norwegian IT experts
2011
ContextThe assumption of the presented work is that the ability of system developers and IT operations personnel to cooperate effectively in system development projects has great impact on the quality of the final system solution, as well as on the service level of its subsequent operation. ObjectiveThe present research explores the interplay of system development and IT operations and the challenges they are meeting. We are especially interested in identifying problems encountered between these two parties in system development projects. MethodWe identify and rank problems by using a ranking-type Delphi study. We involved 42 Norwegian IT experts and split them into three expert panels: sys…
An FPGA-Based Software Defined Radio Platform for the 2.4GHz ISM Band
2006
A prototype of a Software Defined Radio (SDR) platform has been successfully designed and tested implementing a reconfigurable IEEE 802.11 and ZigBee receiver. The system exploits the reconfiguration capability of an FPGA for implementing a number of receiver configurations that share the same RF front-end. Configurations can be switched at run time, or can share the available logic and radio resource.
Requirements Engineering and Process Modelling in Software Quality Management— Towards a Generic Process Metamodel
2004
This paper examines the concept of Quality in Software Engineering, its different contexts and its different meanings to various people. It begins with a commentary on quality issues for systems development and various stakeholders' involvement. It revisits aspects and concepts of systems development methods and highlights the relevance of quality issues to the choice of a process model. A summarised review of some families of methods is presented, where their application domain, lifecycle coverage, strengths and weaknesses are considered. Under the new development era the requirements of software development change; the role of methods and stakeholders change, too. The paper refers to the …
Radio measurements on a customized software defined radio module: A case study of energy detection spectrum sensing
2017
In this paper, we developed a software defined radio (SDR) system for implementing energy detection spectrum sensing. The SDR module can be used for a wide range of applications. The use of the SDR module is motivated by its high interoperability, availability for relatively cheaper prices and being software independent. Energy detection for cognitive radios is chosen for its simplicity and popularity. However, it is chosen as a representative for a very wide range of measurements and algorithms that can be implemented in the SDR. We have used probabilities of detection and false alarm with the receiver operating characteristics (ROC) curves as performance metrics for the implemented energy…
