Hochgeschwindigkeits-Schaftfräsen von Einkristall-Siliziumwafern
ISBN: 9786203374520 / Niemiecki / Miękka / 100 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Die Bearbeitung von einkristallinem Silizium ist aufgrund der hohen Härte und der inhärenten Sprödigkeit des Materials eine herausfordernde und teure Angelegenheit. Das Hauptproblem bei der herkömmlichen Bearbeitung spröder Materialien wie Silizium ist die Erzeugung von Rissen und Beschädigungen unter der Oberfläche. Dieses Buch beschreibt ein duktiles Bearbeitungsverfahren, das für Silizium unter Verwendung eines Hochgeschwindigkeits-Schaftfräsens unter Verwendung diamantbeschichteter Werkzeuge entwickelt wurde. Es wurde festgestellt, dass die entwickelte Methode die Unversehrtheit...

Fraisage en bout à grande vitesse d'une plaquette de silicium monocristallin
ISBN: 9786203374544 / Francuski / Miękka / 96 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. L'usinage du silicium monocristallin est une affaire difficile et coûteuse en raison de la dureté élevée et de la fragilité inhérente du matériau. Le problème majeur dans l'usinage conventionnel de matériaux fragiles comme le silicium est la génération de fissures et de dommages sous la surface. Ce livre décrit un processus d'usinage en mode ductile développé pour le silicium utilisant un fraisage en bout à grande vitesse à l'aide d'outils diamantés. La méthode développée s'est avérée assurer l'intégrité de la surface usinée et une bonne finition de surface....

The Informal Sector in Asia
ISBN: 9783639241563 / Angielski / Miękka / 2010 / 144 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Many contemporary societies are in turmoil for widespread poverty, joblessness, socio-economic polarization and environmental degradation. Every government now utilizes the free market system and profit motive for economic growth and development. No government however is seriously engaged in reducing inequalities, creating employment, provisioning basic services and reversing environmental degradation. As a result, most people, particularly the children, the women and the old work and live precariously. It is in this distressing background that this book analyses the informal sector growth...

High Speed Machining of Titanium Alloy, Ti6al4v
ISBN: 9783659219597 / Angielski / Miękka / 2012 / 128 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. High speed end milling of Titanium alloy Ti6Al4V is a potential machining technique for obtaining nano level surface finish using small diameter (2mm and 4mm) tools applying high rpm to facilitate the application of of low values (micro-meter level) of feeda and depth of cut to ensure super finishing that could avoid the need of further grinding and polishing operations. Influences of three cutting parameters, namely cutting speed, axial depth of cut and feed, were analyzed. Mathematical models were developed for output responses Ra and Rt. Analysis of multiple response optimizations of RSM...

ISBN: 9783838373072 / Angielski / Miękka / 2011 / 172 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Titanium alloys are generally regarded as difficult- to-cut materials and plentiful research works have been conducted on their machinability in the past few decades with several diverse objectives, such as improvement on tool life, surface finish and surface integrity, investigation on chip and tool wear morphology, cutting force and vibration/chatter. This study introduces induction preheating as one of the new variable parameters to improve the machinability of titanium Ti-6Al-4V alloy. In the current work the influence of heating parameter i.e. preheating temperature, and the...

Reproductive Biology of Green Mussel Perna viridis (Linnaeus 1758)
ISBN: 9783844392982 / Angielski / Miękka / 104 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. This book is the result of four years Ph.D. research on the green mussel Perna viridis (Linnaeus 1758) from the high spat-fall coastal waters of Malacca, Peninsular Malaysia. Marine mussels form one of the most dominant cultivable species all over the world. They provide the highest conversion of primary producers (phytoplankton) to human food as a low-priced source of animal protein. Perna viridis occurs widely in shallow waters along the west coast of Peninsular Malaysia allowing mussel seeds to be readily available for culture practice. Most of the previous studies tackling the collection...
