Primary Systems and Voter Turnout: Measuring the Institutional Effect of Primary Type on Voter Turnout
… this study looks at whether the type of primary system in a person's state has an effect on whether or not that person will vote in the general election. The five types of primary systems (closed, semi-closed, semiopen, open and blanket) are explained as well as traditional factors for …

The tuned mass damper inerter for passive vibration control and energy harvesting in dynamically excited structural systems
… classical TMD. For linear harmonically excited primary systems, analytical closed-form expressions are derived for optimal TMDI design/tuning parameters using the well-established and widely applied for the case of the classical TMD semi-empirical fixed-point theory. It is shown that for the …

Digitale Geschäftsmodelle im Schweizer Gesundheitswesen: theoretische und empirische Analyse ihrer Wirkung auf integrierte Versorgung
… of value propositions, integration with primary systems, and protected pilot environments. Organisational readiness outweighed external framework conditions. Limitations concern the non-probabilistic sampling, sample size, and restricted reliability of individual environmental indices. …

Development of an early stage ship design tool for rapid modeling in Paramarine
… a visual model of a basic naval vessel with primary systems and equipment from relatively few initial user inputs while embodying a depth of user-changeable default settings for more complex and non-standard design efforts. Several case studies were run to show the capability and flexibility …

Non-destructively detecting spinodal decomposition at a distance towards developing gigahertz ultrasonics for in-vessel inspection
… such as core barrels, steam generator tubes, or primary coolant pipes and are often required by policy, such as NRC policy 10-CFR-50.65. Here we demonstrate the use of gigahertz, non-contact ultrasonics to gauge the state of cast austenitic stainless steels (CASS), used in some of the largest …

Multi-Degree of Freedom Passive and Active Vibration Absorbers for the Control of Structural Vibration
… to couple into modes of a distributed primary system to improve the attenuation of structural resonance. By choosing the coupling positions of the MDOF absorber such that its mode shape mirrors that of the primary system, the mass of the absorber can be utilized at multiple resonance …

The generation and classification of small leaks in a high pressure water system
… the detection of small leaks from the primary system of a Nuclear Pressurised Water Reactor. Leak rates of 12 g/s are invariably difficult to detect and locate. The typical leak indicators in a nuclear reactor control room are a drop in pressure and level from the pressuriser, and the …

Advanced experimental characterization of deformation mechanisms and temperature changes on novel alloys systems
… continues to benefit from novel alloys systems ascribed to their unprecedented functionalities. Among many, shape memory alloys (SMAs) and high entropy alloys (HEAs) are presently of great research interest in material science and engineering community. Unlike conventional alloys, the …

The development of an experimental technique to measure the influence of temperature on the mechanical properties of weldments
… for approximately 24 year (± 212 000 hrs). Two primary systems namely the Gleeble 3800 thermo-mechanical simulator and digital image correlation are used in this study. In order to accurately map the in-service evolution of material properties, each of the welds were mechanically loaded in …
