-
Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- Elgar Research Agendas outline the future of research in a given area. Leading scholars are given the space to explore their subject in provocative ways, and map out the potential directions of travel. They are relevant but also visionary.There is growing recognition that entrepreneurship can be better understood within its context(s). This carefully designed book invites readers to take a journey: from reflecting critically on where the discussion on context and entrepreneurship stands today towards identifying future research questions and themes that deserve the attention of entrepreneurship scholars. This collection draws attention to the research challenges the entrepreneurship field faces by reviewing the many facets of contexts and by reflecting on methods and theoretical approaches that are required in order to contextualize entrepreneurship research. Written by renowned international scholars, the book's leading-edge contributions provide a thorough exploration of how to contextualize entrepreneurship research. Taking a multidisciplinary approach, comprehensive coverage of the entrepreneurship/contexts debate is included, in addition to reading lists and a chapter dedicated to advancing future research avenues. Students and academics interested in context and entrepreneurship will benefit from this far-reaching and forward-thinking book.

Olika publiker, olika livsstilar : Om idrott, kultur och regional utveckling
- 2008
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- I föreliggande rapport studeras vilka sociala värden som elitidrotten och kulturen genererar för invånarna i landsortspräglade län som Blekinge, Halland, Kalmar och Kronoberg. Studien syftar till att lämna ett bidrag till den samhällsvetenskapliga idrottsforskningen, och ge ökad kunskap om idrottens och kulturens betydelse för den regionala utvecklingen. Studiens material vilar på en postenkät skickad till 1500 slumpmässigt utvalda personer i respektive län. Det sammanlagda antalet besvarade enkäter uppgick till 3181 stycken, vilket ger en nettosvarsfrekvens på 54 procent. Rapporten visar bland annat att både idrott och kultur värderas relativt högt och konsumeras i relativt stor utsträckning. Beträffande idrott konsumeras främst breddidrottsliga evenemang, och vad gäller kultur besöks bibliotek och biografer oftare än exempelvis teatrar. Studien visar också att de kultur- respektive idrottsintresserade skiljer sig åt vad gäller demografi, men även vad gäller livsstil. De idrottsintresserade har en mer folklig och lantlig prägel, medan de kulturintresserade är att betrakta som en välutbildad kosmopolitisk grupp. Med tanke på de sistnämndas ökade rörlighet är satsningar på kultur ej att förringa. Denna typ av satsningar kan få denna resursstarka grupp att dels stanna kvar i landsorten, dels flytta in till densamma.

ASPLe : a methodology to develop self-adaptive software systems with reuse
- 2017
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Advances in computing technologies are pushing software systems and their operating environments to become more dynamic and complex. The growing complexity of software systems coupled with uncertainties induced by runtime variations leads to challenges in software analysis and design. Self-Adaptive Software Systems (SASS) have been proposed as a solution to address design time complexity and uncertainty by adapting software systems at runtime. A vast body of knowledge on engineering self-adaptive software systems has been established. However, to the best of our knowledge, no or little work has considered systematic reuse of this knowledge. To that end, this study contributes an Autonomic Software Product Lines engineering (ASPLe) methodology. The ASPLe is based on a multi-product lines strategy which leverages systematic reuse through separation of application and adaptation logic. It provides developers with repeatable process support to design and develop self-adaptive software systems with reuse across several application domains. The methodology is composed of three core processes, and each process is organized for requirements, design, implementation, and testing activities. To exemplify and demonstrate the use of the ASPLe methodology, three application domains are used as running examples throughout the report.

Designing Self-Adaptive Software Systems with Reuse
- 2018
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Modern software systems are increasingly more connected, pervasive, and dynamic, as such, they are subject to more runtime variations than legacy systems. Runtime variations affect system properties, such as performance and availability. The variations are difficult to anticipate and thus mitigate in the system design.Self-adaptive software systems were proposed as a solution to monitor and adapt systems in response to runtime variations. Research has established a vast body of knowledge on engineering self-adaptive systems. However, there is a lack of systematic process support that leverages such engineering knowledge and provides for systematic reuse for self-adaptive systems development. This thesis proposes the Autonomic Software Product Lines (ASPL), which is a strategy for developing self-adaptive software systems with systematic reuse. The strategy exploits the separation of a managed and a managing subsystem and describes three steps that transform and integrate a domain-independent managing system platform into a domain-specific software product line for self-adaptive software systems.Applying the ASPL strategy is however not straightforward as it involves challenges related to variability and uncertainty. We analyzed variability and uncertainty to understand their causes and effects. Based on the results, we developed the Autonomic Software Product Lines engineering (ASPLe) methodology, which provides process support for the ASPL strategy. The ASPLe has three processes, 1) ASPL Domain Engineering, 2) Specialization and 3) Integration. Each process maps to one of the steps in the ASPL strategy and defines roles, work-products, activities, and workflows for requirements, design, implementation, and testing. The focus of this thesis is on requirements and design.We validate the ASPLe through demonstration and evaluation. We developed three demonstrator product lines using the ASPLe. We also conducted an extensive case study to evaluate key design activities in the ASPLe with experiments, questionnaires, and interviews. The results show a statistically significant increase in quality and reuse levels for self-adaptive software systems designed using the ASPLe compared to current engineering practices.

Smart Forest Observatories Network : A MAPE-K Architecture Based Approach for Detecting and Monitoring Forest Damage
- 2023
-
Ingår i: Proceedings of the Conference Digital solutions for detecting and monitoring forest damage.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Forests are essential for life, providing various ecological, social, and economic benefits worldwide. However, one of the main challenges faced by the world is the forest damage caused by biotic and abiotic factors. In any case, the forest damages threaten the environment, biodiversity, and ecosystem. Climate change and anthropogenic activities, such as illegal logging and industrial waste, are among the principal elements contributing to forest damage. To achieve the United Nations' Sustainable Development Goals (SDGs) related to forests and climate change, detecting and analyzing forest damages, and taking appropriate measures to prevent or reduce the damages are essential. To that end, we envision establishing a Smart Forest Observatories (SFOs) network, as shown below, which can be either a local area or a wide area network involving remote forests. The basic idea is to use Monitor, Analyze, Plan, Execute, and Knowledge (MAPE-K) architecture from autonomic computing and self-adaptive software systems domain to design and develop the SFOs network. The SFOs are planned to collect, analyze, and share the collected data and analysis results using state-of-the-art methods. The principal objective of the SFOs network is to provide accurate and real-time data to policymakers and forest managers, enabling them to develop effective policies and management strategies for global forest conservation that help to achieve SDGs related to forests and climate change.

Towards Autonomic Software Product Lines (ASPL) - A Technical Report
- 2011
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This report describes a work in progress to develop Autonomic Software Product Lines (ASPL). The ASPL is a dynamic software product line approach with a novel variability handling mechanism that enables traditional software product lines to adapt themselves at runtime in response to changes in their context, requirements and business goals. The ASPL variability mechanism is composed of three key activities: 1) context-profiling, 2) context-aware composition, and 3) online learning. Context-profiling is an offline activity that prepares a knowledge base for context-aware composition. The context-aware composition uses the knowledge base to derive a new product or adapts an existing product based on a product line's context attributes and goals. The online learning optimizes the knowledge base to remove errors and suboptimal information and to incorporate new knowledge. The three activities together form a simple yet powerful variability handling mechanism that learns and adapts a system at runtime in response to changes in system context and goals. We evaluated the ASPL variability mechanism on three small-scale software product lines and got promising results. The ASPL approach is, however, is yet at an initial stage and require improved development support with more rigorous evaluation.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Studies with large physical models are a vital link between the theoretical work and field applications provided that these models are designed to represent real structures where various types and levels of uncertainties can be incorporated. While comprehensive analytical and laboratory joint studies are ongoing at Qatar University, University of Central Florida and University of Alberta, this paper presents the initial findings of dynamic testing at Qatar University. A laboratory stadium structure (grandstand simulator) has been constructed at Qatar University. Capable of housing thirty spectators, Qatar University grandstand simulator is arguably the largest laboratory stadium in the world. The structure is designed in a way that several different structural configurations can be tested in laboratory conditions to enable researchers to test newly developed damage detection algorithms. The study presented in this paper covers the finite element modeling and modal testing of the test structure.

- Metamaterial inspired structures, or metastructures, are structural members that incorporate periodic or non-periodic inserts. Recently, a new class of metastructures has been introduced which feature chiral lattice inserts. It was found that this type of inserts has frequency bandgaps which can be tuned by altering the geometry of the chiral lattice. Previous studies have shown that inserting non-periodic chiral lattices inside a beam-like structure results in efficient vibration attenuation at low frequencies. In the study presented in this paper, a genetic algorithm based optimization technique is developed to automatically generate chiral lattices which are tuned to suppress vibration in a flexible beam-like structure. Several parameters are incorporated in the optimization process such as the radius of circular nodes and characteristic angle as well as the spacing and distribution of circular inserts. The efficiency of the …
