Hyperelastic constants from a modified hardness test using energy balance obtained from FE-analysis

Manufacturing test specimens, testing them in the laboratory and evaluat- ing material parameters for finite element analysis is costly and time consum- ing. In order to simplify the hyperelastic characterisation of rubber materials an extension of the standard hardness test is here proposed. A number of indentation depths are chosen for the hardness test and the indentation forces for these depth

Sprays thermometry using two color LIF and SLIPI

Knowing the droplets temperature is of great importance in spray-assisted combustion devices as it directly affects the droplet evaporation rate. This information helps optimizing the fuel/air mixture formation for the improvement of combustion devices. To measure the temperature of spray droplets, optical techniques such as Rainbow-Refractrometry (for point-wise) and the two-color LIF ratio therm

Curation: Frameworks For A Robust Definition

Drawing on a critical reading of framings which position public relations as a discipline concerned with ‘reputation management’ this study examines the implications of the dynamic tensions between projected organisational reputation and reputation constructed by a network of stakeholders, and builds a framework for the first stringent, academic definition of ‘curation’ that allows a nuanced under

The Hadronic Light-by-Light Contribution to the Muon Anomalous Magnetic Moment: Where do we stand?

We review the status of the hadronic light-by-light contribution to the muon anomalous magnetic moment and critically compare recent calculations. We also study in detail which momentum regions the pi0 exchange main contribution originates. We also argue that amu{light-by-light} = (11 pm 4) times 10-10 encompasses the present understanding of this contribution and comment on some directions to imp

Photon Dose Calculations in a Fluence-Based Treatment Planning System: Data Processing, Implementation and Validation

Popular Abstract in Swedish Framgångsrik strålbehandling av cancerpatienter kräver att man kan bestämma den absorberade dosen i patienten med stor noggrannhet. Bara några enstaka procents avvikelse i absorberad dos kan ha betydelse för det kliniska resultatet avseende både tumörutläkning och normalvävnadsreaktioner. För att beräkna den absorberade dosen i patienten används sofistikerade datorprogThe accuracy of dose calculations for various aspects of a treatment planning system (TPS) using an energy fluence beam modelling has been evaluated. The investigated TPS uses a beam model, which separates the energy fluence into a number of sources in the treatment head. The energy fluence components are transported towards the patient and, together with the scatter generated in the patient, yiel

Food for Naught : The politics of food in agricultural modernization for African smallholder food security

Why is there hunger in sub-Saharan Africa? What forces drive the global food system? What is the global food system? To approach these questions, this study investigates power and politics in food, in its production and in its organization. Proceeding from a critical realist approach, focus of this study is on the challenge of African smallholder food insecurity and how it is presented as part of
