Buch. Zustand: Neu. Neuware -Statistical practices have recently been questioned by numerous independent authors, to the extent that a significant fraction of accepted research findings can be questioned. This suggests that statistical methodologies may have gone too far into an engineering practice, with minimal concern for their foundation, interpretation, assumptions, and limitations, which may be jeopardized in the current context. Disguised by overwhelming data sets, advanced processing, and stunning presentations, the basic approach is often intractable to anyone but the analyst. The hierarchical nature of statistical inference, exemplified by Bayesian aggregation of prior and derived knowledge, may also be challenging. Conceptual simplified studies of the kind presented in this book could therefore provide valuable guidance when developing statistical methodologies, but also applying state of the art with greater confidence.Books on Demand GmbH, Überseering 33, 22297 Hamburg 158 pp. Englisch.

Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The volatility of the economy, political instability, and greater demands on not-for-profit organisations (non-profits) will require considerable rethinking and refocusing for many organisations. These days, non-profits evolve while attempting to regain financial ground, focusing more on workflow, fundraising, and staffing. The book highlights the upcoming challenges, among others funding instability, with a continuing shift in funding with more grantors focusing on funding mobilisation instead of intervention. Another challenge is clustering, which is where organisations are more likely to band together with others to share overhead costs, resources, and personnel. The non-profit sector will undergo essential integrations where the free flow of data and information will be crucial. Non-profits will continue to adjust their goals and priorities to meet changing trends. While the top priority was once acquiring new donors, that has now been eclipsed by the need for non-profits to engage the community and promote general brand awareness. 92 pp. Englisch.

Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Thermosoftening Plastics are polymers that can be manipulated into different shapes when they are hot, and the shape sets when it cools. If we were to reheat the polymer again, we could re-shape it once again. Modern thermosoftening plastics soften at temperatures anywhere between 65 ºC and 200 ºC. In this state, they can be moulded in a number of ways. They differ from thermoset plastics in that they can be returned to this plastic state by reheating. They are then fully recyclable because thermosoftening plastics do not have covalent bonds between neighbouring polymer molecules. Methods of shaping the softened plastic include: injection moulding, rotational moulding, extrusion, vacuum forming, and compression moulding. The scope of this book covers three areas of thermosoftening plastics, thermoplastic materials, and their characterization. The following tests are covered in the book: thermal analysis (differential scanning calorimetry, heat deflection temperature test), optical properties tests (fluorescence spectroscopy, UV spectroscopy), and mechanical properties tests (thermogravimetry, rheometry, short term tensile test). 124 pp. Englisch.
