  • Adapting remote labs to learning scenarios : Case studies using VISIR and remotElectLab
  • 2014
  • Ingår i: Revista Iberoamericana de Tecnologias del Aprendizaje. - Education Society of IEEE (Spanish Chapter). - 1932-8540. ; 9:1, s. 33-39
  • Tidskriftsartikel (refereegranskat)abstract
    • Remote laboratories are an emergent technological and pedagogical tool at all education levels, and their widespread use is an important part of their own improvement and evolution. This paper describes several issues encountered on laboratorial classes, on higher education courses, when using remote laboratories based on PXI systems, either using the VISIR system or an alternate in-house solution. Three main issues are presented and explained, all reported by teachers, that gave support to students' use of remote laboratories. The first issue deals with the need to allow students to select the actual place where an ammeter is to be inserted on electric circuits, even incorrectly, therefore emulating real-world difficulties. The second one deals with problems with timing when several measurements are required at short intervals, as in the discharge cycle of a capacitor. In addition, the last issue deals with the use of a multimeter in dc mode when reading ac values, a use that collides with the lab settings. All scenarios are presented and discussed, including the solution found for each case. The conclusion derived from the described work is that the remote laboratories area is an expanding field, where practical use leads to improvement and evolution of the available solutions, requiring a strict cooperation and information-sharing between all actors, i.e., developers, teachers, and students.

  • The study of urban form in Sweden
  • 2009
  • Ingår i: Urban Morphology. - INT SEMINAR URBAN FORM. - 1027-4278. ; 13:2, s. 121-127
  • Tidskriftsartikel (refereegranskat)abstract
    • Early research on urban form in Sweden was undertaken before the First World War. After the Second World War research was influenced by the major criticisms levelled at comprehensive urban renewal and suburban mass housing. These criticisms were particularly on the ground that values embodied in the traditional built environment were being ignored. Increased interest in the study of historical urban fabrics was associated with the development of methodologies reliant on the concepts of typology and morphology. These development were dependent on the activities of individual researchers until the very recent development of wider co-ordinating research organizations.

  • Executing Boolean queries on an encrypted Bitmap index
  • 2016
  • Ingår i: CCSW 2016 - Proceedings of the 2016 ACM Cloud Computing Security Workshop, co-located with CCS 2016. - Association for Computing Machinery (ACM). - 9781450345729 ; s. 11-22
  • Konferensbidrag (refereegranskat)abstract
    • We propose a simple and efficient searchable symmetric encryption scheme based on a Bitmap index that evaluates Boolean queries. Our scheme provides a practical solution in settings where communications and computations are very constrained as it offers a suitable trade-off between privacy and performance.

  • Trend analysis to automatically identify heat program changes
  • 2017
  • Ingår i: Energy Procedia. - Elsevier. ; s. 407-415
  • Konferensbidrag (refereegranskat)abstract
    • The aim of this study is to improve the monitoring and controlling of heating systems located at customer buildings through the use of a decision support system. To achieve this, the proposed system applies a two-step classifier to detect manual changes of the temperature of the heating system. We apply data from the Swedish company NODA, active in energy optimization and services for energy efficiency, to train and test the suggested system. The decision support system is evaluated through an experiment and the results are validated by experts at NODA. The results show that the decision support system can detect changes within three days after their occurrence and only by considering daily average measurements.

  • Teaching Ethics in Schools of Public Health in the European Region Findings from a Screening Survey
  • 2012
  • Ingår i: Public Health Reviews. - Public Health Reviews. - 0301-0422. ; 34:1, s. 1-10
  • Tidskriftsartikel (refereegranskat)abstract
    • A survey targeting ASPHER members was launched in 2010/11, being a first initiative in improving ethics education in European Schools of Public Health. An 8-items questionnaire collected information on teaching of ethics in public health. A 52% response rate (43/82) revealed that almost all of the schools (95% out of 40 respondents with valid data) included the teaching of ethics in at least one of its programmes. They also expressed the need of support, (e.g.: a model curriculum (n=25), case studies (n=24)), which indicates further work to be met by the ASPHER Working Group on Ethics and Values in Public Health.

  • Developing Inclusive Innovation Processes and Co-Evolutionary University-Society Approaches in Bolivia
  • 2018
  • Doktorsavhandling (övrigt vetenskapligt)abstract
    • This study is part of a worldwide debate on inclusive innovation systems in developingcountries and particularly on the co-evolutionary processes taking place, seen from theperspective of a public university. The increasing literature that discusses how innovationsystems and development can foster more inclusive and sustainable societies hasinspired this thesis work. Thus, the main problem handled in the research concerns thequestion how socially sensitive research practices and policies at a public university inBolivia can be stimulated within emerging innovation system dynamics. In that vein,empirical knowledge is developed at the Universidad Mayor de San SimoÅLn (UMSS),Cochabamba as a contribution to experience-based learning in the field. Analysis arenourished by a dialogue with the work of prominent Latin American scholars andpractitioners around the idea of a developmental university and the democratizationof knowledge. The reader will be able to recognize a recursive transit between theoryand practice, where a number of relevant concepts are contextualized and connectedin order to enable keys of critical interpretation and paths of practices amplificationfor social inclusion purposes established. The study shows how, based on a previousexperience, new competences and capacities for the Technology Transfer Unit (UTT)at UMSS were produced, in this case transforming itself into a University InnovationCentre. Main lessons gained in that experience came from two pilot cluster development(food and leather sectors) and a multidisciplinary researchers network (UMSSInnovation Team) where insights found can improve future collaborative relations betweenuniversity and society for inclusive innovation processes within the Boliviancontext.

  • Developing Inclusive Innovation Processes and Co-Evolutionary Approaches in Bolivia
  • 2015
  • Licentiatavhandling (övrigt vetenskapligt)abstract
    • The concept of National Innovation Systems (NIS) has been widely adopted in developing countries, particularly in Latin American countries, for the last two decades. The concept is used mainly as an ex-ante framework to organize and increase the dynamics of those institutions linked to science, technology and innovation, for catching-up processes of development. In the particular case of Bolivia, and after several decades of social and economic crisis, the promise of a national innovation system reconciles a framework for collaboration between the university, the government and the socio-productive sectors. Dynamics of collaboration generated within NIS can be a useful tool for the pursuit of inclusive development ambitions. This thesis is focused on inclusive innovation processes and the generation of co-evolutionary processes between university, government and socio-productive sectors. This is the result of 8 years of participatory action research influenced by Mode 2 knowledge-production and Technoscientific approaches. The study explores the policy paths the Bolivian government has followed in the last three decades in order to organize science, technology and innovation. It reveals that Bolivia has an emerging national innovation system, where its demand-pulled innovation model presents an inclusive approach. Innovation policy efforts in Bolivia are led by the Vice-Ministry of Science and Technology (VCyT). Moreover, NIS involves relational and collaborative approaches between institutions, which imply structural and organizational challenges, particularly for public universities, as they concentrate most of the research capabilities in the country. These universities are challenged to participate in NIS within contexts of weak demanding sectors.  This research focuses on the early empirical approaches and transformations at Universidad Mayor de San Simón (UMSS) in Cochabamba. The aim to strengthen internal innovation capabilities of the university and enhance the relevance of research activities in society by supporting socio-economic development in the framework of innovation systems is led by the Technology Transfer Unit (UTT) at UMSS. UTT has become a recognized innovation facilitator unit, inside and outside the university, by proposing pro-active initiatives to support emerging innovation systems. Because of its complexity, the study focuses particularly on cluster development promoted by UTT. Open clusters are based on linking mechanisms between the university research capabilities, the socio-productive actors and government. Cluster development has shown to be a practical mechanism for the university to meet the demanding sector (government and socio-productive actors) and to develop trust-based inclusive innovation processes. The experiences from cluster activities have inspired the development of new research policies at UMSS, with a strong orientation to foster research activities towards an increased focus on socio-economic development. The experiences gained at UMSS are discussed and presented as a “developmental university” approach. Inclusive innovation processes with co-evolutionary approaches seem to constitute an alternative path supporting achievement of inclusive development ambitions in Bolivia.

  • Philippe Aghion recipient of the 2016 Global Award for Entrepreneurship Research
  • 2017
  • Ingår i: Small Business Economics. - Springer. - 0921-898X. ; 48:1, s. 1-8
  • Tidskriftsartikel (refereegranskat)abstract
    • Professor Philippe Aghion is the 2016 recipient of the Global Award for Entrepreneurship Research, consisting of 100,000 Euros and a statuette designed by the internationally renowned Swedish sculptor Carl Milles. He is one of the most influential researchers worldwide in economics in the last couple of decades. His research has advanced our understanding of the relationship between firm-level innovation, entry and exit on the one hand, and productivity and growth on the other. Aghion has thus accomplished to bridge theoretical macroeconomic growth models with a more complete and consistent microeconomic setting. He is one of the founding fathers of the pioneering and original contribution referred to as Schumpeterian growth theory. Philippe Aghion has not only contributed with more sophisticated theoretical models, but also provided empirical evidence regarding the importance of entrepreneurial endeavours for societal prosperity, thereby initiating a more nuanced policy discussion concerning the interdependencies between entrepreneurship, competition, wealth and growth.

  • A Sandboxing Method to Protect Cloud Cyberspace
  • 2015
  • Ingår i: PROCEEDINGS OF 2015 IEEE EAST-WEST DESIGN & TEST SYMPOSIUM (EWDTS). - IEEE Communications Society. - 978-1-4673-7776-8
  • Konferensbidrag (refereegranskat)abstract
    • This paper addresses the problem of protecting cloud environments against targeted attacks, which have become a popular mean of gaining access to organization's confidential information and resources of cloud providers. Only in 2015 eleven targeted attacks have been discovered by Kaspersky Lab. One of them - Duqu2 - successfully attacked the Lab itself. In this context, security researchers show rising concern about protecting corporate networks and cloud infrastructure used by large organizations against such type of attacks. This article describes a possibility to apply a sandboxing method within a cloud environment to enforce security perimeter of the cloud.
