• Creep refers to the slow, permanent deformation of materials under external loads, or stresses. It explains the creep strength or resistance to this extension. This book is for experts in the field of strength of metals, alloys and ceramics. It explains creep behavior at the atomic or ?dislocation defect level. This book has many illustrations and many references. The figure formats are uniform and consistently labeled for increased readability. This book is the second edition that updates and improves the earlier edition.

• Bachelor Thesis from the year 2013 in the subject Electrotechnology, grade: Bachelor, Harbin Engineering University (College of Automation), course: Electronics, language: English, abstract: In recent years, with the development of power electronic devices?control theory and the increasing demand of high-quality power supply, power electronics technology has aroused widely attention from scholars. DC-DC power converters are employed in a variety of applications, including power supplies for personal computers, office equipment; spacecraft power systems, laptop, Cell phones, and telecommunications equipment, as well as dc motor drives. In this project a detailed study of zero current switching buck converters is done and also practically implemented in hardware. In addition a mathematical analysis of switching loss occurring in MOSFET's is also presented and a short study of zero voltage switching is also appended. During the hardware implementation the Ton, Toff and operating frequency were found out and thoroughly tuned through the IC555 circuit and various waveforms across inductors, capacitors, load resistor and test points were noted down. In this thesis, the Buck type circuit structure and working principle are analyzed and a DC-DC buck converter is designed. The designed converter uses ZCS scheme and realized the function that the power form is converted from 12V DC voltages to 5 V DC voltages. The output voltage can be adjusted according to the output resistor. The output voltage is stable and the performance of the designed converter is ensured. Simulation study was carried out and effectiveness of the designed converter is verified by simulation results. Finlay design is implemented in hardware and PCB layout as well.

• The amount and variety of waste that humanity dumps in landfill sites is nothing short of a scandal, believes Rafat Siddique, of Deemed University in Patiala, India. Instead, we ought to be building new homes out of it! Siddique shows in this important book that many non-hazardous waste materials and by-products which are landfilled, can in fact be used in making concrete and similar construction materials.

• Chemical admixtures are used in concrete mixtures to produce particular engineering properties such as rapid hardening, water-proofing or resistance to cold. Chemical Admixtures for Concrete surveys recent developments in admixture technology, explaining the mechanisms by which admixtures produce their effects, the various types of admixtures available, their selection and use.
• Because of the economies they can offer, admixtures are being used increasingly in civil engineering projects worldwide. The book pays particular attention to good practice and includes a detailed chapter on the international standards currently in force.
