Material Issues of the Metal Printing Process, MPP

The metal printing process, MPP; is a novel Rapid Manufacturing process under development at SINTEF and NTNU in Trondheim, Norway. The process, which aims at the manufacturing of end-use products for demanding applications in metallic and CerMet materials, consists of two separate parts; The layer fabrication, based on electrostatic attraction of powder materials, and the consolidation, consisting of the compression and sintering of each layer in a heated die. This approach leads to a number of issues regarding the interaction between the process solutions and the materials. This paper addresses some of the most critical material issues at the current development stage of MPP, and the present solutions to these.Mechanical Engineerin

Electoral participation in the Netherlands: Individual and contextual influences

AbstractResearch into electoral participation has produced two traditions, one focusing mainly on individual level explanations while the second concentrates primarily on aggregate level explanations. By bringing these two research approaches together, we are not only able to explain individual electoral participation more thoroughly, but we also gain additional insight into the influence of aggregate level characteristics on individual behavior. We combine eight National Election Studies held in the Netherlands between 1971 and 1994 enabling us to study variation on the individual and the contextual (aggregate) level, including interactions between these two levels. Findings show that the addition of contextual characteristics form a significant improvement to an individual level model predicting electoral participation. Findings also confirm our expectation that the influence of individual characteristics such as education or political interest is dependent upon contextual characteristics describing for instance the salience of the election

Online tracking: Questioning the power of informed consent

Online tracking technologies have raised considerable concerns regarding privacy and the protection of personal data of users. In order to help users to regain control over their personal data, Europe has amended its ePrivacy directive towards an opt-in regime. There are however many open questions concerning its implementation, especially regarding the issue of informed consent. This paper explores how the new legal situation impacts on behavioral advertising practices via the storing and reading of cookies in the Netherlands. The results show that the majority of the surveyed parties involved in behavioural advertising do not inform users about the storing of cookies or the purposes of data processing of the subsequently obtained data, neither do they have obtained users' consent for the storage of cookies. We also found that the majority of users lack the skills and knowledge how to handle cookies. These findings critically question the wisdom of the informed consent regime which lies currently at the heart of Europe's ePrivacy directive. --Online behavioural advertising,profiling,cookies,informed consent,Do Not Track,ePrivacy Directive
