Actuating materials hold a promise for fast-spreading applications in smart structures and active control systems, and have attracted extensive attention from scientists of both mechanics and materials sciences communities. High performance and stability of actuating materials and structures play a decisive role in their successive applications as sensors and actuators in structural control and robotics. The advances of actuating materials, however, recently encountered a severe reliability issue. For a better understanding toward this issue, scientific efforts are of paramount significance to gain a deep insight into the intricate deformation and failure behaviors of actuating materials. To examine the state of the art in this subject, the general assembly of IUTAM approved in August, 2002 at Cambridge University, UK, a proposal to hold an IUTAM symposium to summarize the relevant research findings. The main themes of the symposium are: (i) the constitutive relations of actuating materials that couple mechanical, electrical, thermal and magnetic properties, as well as incorporate phase transformation and domain switch; (ii) the physical mechanisms of deformation, damage, and fatigue crack growth of actuating materials; (iii) the development of failure-resilient approaches that base on the macro-, meso-, and micro-mechanics analyses; (iv) the investigation of microstructural evolution, stability of phase transformation, and size effects of ferroelectric ceramics, shape memory alloys, actuating polymers, and bio-actuating materials. The above problems represent an exciting challenge and form a research thrust of both materials science and solid mechanics. The IUTAM Symposium (GA.

This volume is a collection of twenty five written contributions by distinguished invited speakers from seven countries to the IUTAM Symposium on Size Effects on Material and Structural Behavior at Micron- and Nano-scales. Size effects on material and structural behaviors are of great interest to physicists, material scientists, and engineers who need to understand and model the mechanical behavior of solids especially at micron- and nano-scales.

During the last decades, the growth of micro-electronics has reduced the cost of computing power to a level acceptable to industry and has made possible sophisticated control strategies suitable for many applications. Vibration c- trol is applied to all kinds of engineering systems to obtain the desired dynamic behavior, improved accuracy and increased reliability during operation. In this context, one can think of applications related to the control of structures’ vib- tion isolation, control of vehicle dynamics, noise control, control of machines and mechanisms and control of ?uid-structure-interaction. One could continue with this list for a long time. Research in the ?eld of vibration control is extremely comprehensive. Pr- lems that are typical for vibration control of nonlinear mechanisms and str- tures arise in the ?elds of modeling systems in such a way that the model is suitable for control design, to choose appropriate actuator and sensor locations and to select the actuators and sensors. Theobjective of the Symposium was to present anddiscuss methodsthat contribute to thesolution of such problems and to demonstrate the state of the art inthe ?eld shown by typical examples. The intention was to evaluate the limits of performance that can beachievedby controlling the dynamics, and to point out gaps in present research and give links for areas offuture research.Mainly, it brought together leading experts from quite different areas presenting theirpoints of view.

لقد سمته مجلة تايم واحداً من أهم المئة المبتكرين في القرن. طارق رمضان هو من كبار العلماء المسلمين، وله أتباع عديدون لا سيما بين الشباب الأوروبيين والأمريكيين. وفي أول كتاب موجه إلى جمهور واسع فإنه يقدم سيرة رائعة للرسول محمد [ تلقي الضوء على التعاليم الروحية والأخلاقية لواحد من أكثر الشخصيات تأثيراً في تاريخ البشرية. يتضمن هذا الكتاب نظرة جديدة وعميقة إلى محمد [ ويسجل حياة حافلة بكل الأحداث الخطيرة. يرسم رمضان صورة حميمة لرجل يتمتع بالحياء والرقة، ولكنه حازم. والكتاب هو أيضاً تاريخ مثير لزعيم أطلق ديناً عظيماً كان إلهاماً لإمبراطورية شاسعة. والأهم من ذلك أن رمضان يعرض الأحداث الرئيسة من حياة النبي [ بطريقة تلقي الأضواء على تعاليمه الروحية والأخلاقية. ويؤكد الكتاب على أهمية قدوة النبي [ التي يمكن أن تستنير بها معظم قضايا اليوم المثيرة للجدل، مثل معاملة الفقراء ودور المرأة والعقوبات الجزائية الإسلامية والحرب والتعصب العرقي والعلاقات بالديانات الأخرى. وقد اختار المؤلف تلك الحقائق والقصص التي يمكننا أن نرسم استناداً إليها صورة روحية عميقة تنبض بالحياة ويتساءل كيف يمكن لحياة النبي [ أن تظل ـــ أو تصبح مرة ثانية ـــ قدوة ونموذجاً ومصدر إلهام؟ وكيف يمكن للمسلمين أن ينتقلوا من الجمود والتقيد بالطقوس إلى وجود روحي واجتماعي ملتزم؟ في هذه السيرة التي تنطوي على تفكير عميق يقدم رمضان للمسلمين نظرة جديدة إلى حياة محمد [ ويعرف غير المسلمين لا بمجرد قصة النبي [ بل بثروات الإسلام الروحية والأخلاقية. العبيكان 2016
