- Radioactive beams of 14,15B produced by fragmentation of a primary 40Ar beam were directed onto a Pb target to investigate the neutron breakup within the Coulomb field. The experiment was performed at the LAND/R3B setup. Preliminary results for the Coulomb dissociation cross sections as well as for the astrophysically interesting inverse reactions, 13,14B(n,γ), are presented.

- The nucleosynthesis of elements beyond iron is dominated by neutron captures in the s and r processes. However, 32 stable, proton-rich isotopes cannot be formed during those processes, because they are shielded from the s-process flow and r-process beta-decay chains. These nuclei are attributed to the p and rp process. For all those processes, current research in nuclear astrophysics addresses the need for more precise reaction data involving radioactive isotopes. Depending on the particular reaction, direct or inverse kinematics, forward or time-reversed direction are investigated to determine or at least to constrain the desired reaction cross sections. The Facility for Antiproton and Ion Research (FAIR) will offer unique, unprecedented opportunities to investigate many of the important reactions. The high yield of radioactive isotopes, even far away from the valley of stability, allows the investigation of isotopes involved in processes as exotic as the r or rp processes.

The Biodiversity Moonshot: System Thinking to Co-Create a Biodiversity Embedded Future for Companies

- The detrimental consequences for general economic and social well-being as a result of biodiversity loss and the subsequent degradation of natural ecosystems are emerging as a wicked challenge that the whole societal and economic system must urgently faces. The severity of the impacts of incremental biodiversity depletion calls for substantial and imperative action by all actors and in particular by companies and institutions. Moreover, it is also pivotal an in-depth reflection that allows the management studies to develop as a scientific branch and to play its part in the fundamental transition to a biodiversity embedded future for companies. To further stimulate academic debate, this Symposium aims to encourage discussions on how companies can manage their relationship with the natural environment so as not to destroy the very life-supporting foundations provided by biodiversity.

Industry 4.0 readiness in manufacturing companies : Challenges and enablers towards increased digitalization
- 2019

Konferensbidrag (refereegranskat)abstract
- Digitalization is changing the business environment and companies face challenges to make progress. A first step to support companies is to verify their digital readiness, capabilities, and developing clear plans for improvement. This paper aims to evaluate the digital readiness of seven companies through the application of a self-check tool, followed by a deeper investigation through a case study, to identify reasons, challenges/barriers and enablers towards digitalization. A workshop was conducted to evaluate the use of a self-check tool and collect other analysis. Results include the readiness level and comparison between companies, actions and practices towards increased digitalization.

Konferensbidrag (refereegranskat)abstract
- Several authors have been devoted their research projects to understand and map research topics and themes studied in the field of Industrial Engineering (IE), particularly those related to Operations Management (OM), aiming to contribute to the field scope delimitation, identifying for that purpose its main authors and their contribution for theory and practice. This study seeks to frame this knowledge regarding to sustainability research. Bibliometrics and statistics analysis were performed using information collected from 500 selected papers in nine international databases related to OM field, based on the keywords "Sustainability" and "Operations Management". Results point to a central set of nineteen authors whose work is strongly related to sustainability issues. All information are systematized generating descriptive statistics, network graphs and multivariate matrices for research topics, methodologies, outlets, main academic and normative references. Thus, this paper contributes with an overview of trends and gaps for future research in sustainability concerning operations management field.

Optimization of switched-beam arrays for communication systems
- 2014
-

Konferensbidrag (refereegranskat)abstract
- This paper presents the application of optimization methods for the synthesis of a linear array for communication systems. By means of suitably beam switching, the array should provide coverage of a given angular area in azimuth and should allow controlling the sidelobe level simultaneously. For this purpose, two optimization methods have been used to calculate the excitation coefficient for each desired beam. The synthesis technique is demonstrated for arrays composed of isotropic and microstrip elements. By comparing the results obtained for both arrays, the need of consideration of the array element pattern during the synthesis process is demonstrated.
