Analysis of the internal ventilation for a motorcycle helmet
ISBN: 9783639315585 / Angielski / Miękka / 224 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Thermal comfort is a fundamental issue for riders to take care of, especially in countries with very hot summer climate: the temptation of leaving out wearing the helmet turns out to be too strong if it is not sufficiently ventilated, with obvious consequences in terms of risk of injuries for the heat of the rider. For these reasons it is important for each helmet to be equipped with an efficient ventilation system, which should be able to remove the heat and sweat produced by the head of the rider. At the moment there is a total lack of fluid-dynamic guidelines for the design of such...

Contact, Adhesion and Rupture of Elastic Solids
ISBN: 9783642085383 / Angielski / Miękka / 414 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. In 1970 an investigation into rubber friction, sponsored by a manufacturer of automobile windscreen wipers, was being carried out at the Cavendish Laboratory in Cambridge, England. When a smooth spherical slider of soft rubber was placed in contact with flat glass or perspex, the compliance of the rubber enabled it to conform to any slight roughness of the two surfaces such that perfect contact was obtained. In these circumstances the surfaces were found to adhere: under load the contact area exceeded that predicted by the Hertz theory of elastic contact, a contact area of finite size was...

Phase Transitions of Simple Systems
ISBN: 9783642090738 / Angielski / Miękka / 247 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Thermodynamic concepts of aggregate states and their phase transitions - veloped during the 19th Century and are now the basis of our contem- rary understanding of these phenomena. Thermodynamics gives an universal, macroscopic description of the equilibrium properties of phase transitions - dependent of the detailed nature of the substances. However understanding the nature of phase transitions at the microscopic level requires a di?erent approach, one that takes into account the speci?cs of the interparticle int- actions. In this book, we lay the groundwork that connects the microscopic...

Is There a Temperature?: Conceptual Challenges at High Energy, Acceleration and Complexity
ISBN: 9781441980403 / Angielski / Twarda / 310 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Temperature and heat, entropy and order or disorder are key classical concepts of physics. These are challenged by searching matter under extreme conditions, such as high (relativistic) energy, strong acceleration or gravitation, or unusual complexity due to long range correlations. In our quest for quark matter all these conditions might occur simultaneously. This book, strongly motivated by the authors' everyday research experiences in the field of high-energy heavy-ion collisions, aims to bundle these challenges to modern physics. The main topic is at the heart of thermodynamics... Temperature and heat, entropy and order or disorder are key classical concepts of physics.

Constructal Theory of Social Dynamics brings together for the first time social scientists and engineers to develop a predictive theory of social organization, as a conglomerate of mating flows that morph in time to flow more easily (people, goods, money, energy, information). These flows have objectives (e.g., minimization of effort, travel time, cost), and the objectives clash with global constraints (space, time, resources). The result is organization (flow architecture) derived from one principle of configuration evolution in time (the constructal law): "for a...

Miniature Joule-Thomson Cryocooling: Principles and Practice
ISBN: 9781441982841 / Angielski / Twarda / 382 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This book is the first in English being entirely dedicated to Miniature Joule-Thomson Cryocooling. The category of Joule-Thomson (JT) cryocoolers takes us back to the roots of cryogenics, in 1895, with figures like Linde and Hampson. The "cold finger" of these cryocoolers is compact, lacks moving parts, and sustains a large heat flux extraction at a steady temperature. Potentially, they cool down unbeatably fast. For example, cooling to below 100 K (minus 173 Celsius) might be accomplished within only a few seconds by liquefying argon. A level of about 120 K can be reached...
