امروزه ورقهای چند لایه فلزی در صنایع گوناگون از جمله هوا فضا، اتومبیل سازی، صنایع شیمیایی و الکتریکی مورد استفاده قرار میگیرند. مهمترین مزیت ورقهای دو لایه، دستیابی به رسانش الکتریکی و حرارتی بالا، وزن سبک و مقاومت به خوردگی میباشد. عموما، این طرح به دو منظور به کار میرود الف) دستیابی به خواص دو ورق به صورت یکجا و ب) برای بهبود شکل پذیری فلزات کم شکل پذیر. فرایند کشش عمیق به عنوان یکی از پر کاربردترین فرایند های شکلدهی فلزات، در صنایع مختلف مورد استفاده قرار میگیرد. در این عملیات فلزکاری، ورق با استفاده از فشار سنبه به داخل قالب کشیده میشود و در نهایت ورق به صورت یک قطعه فنجانی شکل در میآید. در این فرایند، به مانند اغلب فرایند های شکلدهی فلزات،کرنش های حاصل کششی میباشند. بنابر این برای جلوگیری از پارگی موضعی ورق،پارامترهای موثر باید هوشمندانه انتخاب گردند.

The Iran Nuclear Deal
At the start of each class that I teach at Penn State, I tell the students there are two things that they should know about me. First, that I grew up in New Mexico. Second, that I spent 28 years in the State Department before spending the last 17 as an academic. I then explain the significance of those two facts. First, that there is nothing bad they can say about Texas that I won’t believe. Second, that as a professor of social science at a large, public, northeastern university and a former career bureaucrat, the chances that I am politically liberal and believe there is an important role for government are both in the neighborhood of 99 percent.

Angela Duckworth Grit The Power
Growing up, I heard the word genius a lot.
It was always my dad who brought it up. He liked to say, apropos of nothing at all, “You know, you’re no genius!” This pronouncement might come in the middle of dinner, during a commercial break for The Love Boat, or after he flopped down on the couch with the Wall Street Journal. I don’t remember how I responded. Maybe I pretended not to hear. My dad’s thoughts turned frequently to genius, talent, and who had more than whom. He was deeply concerned with how smart he was. He was deeply concerned with how smart his family was. I wasn’t the only problem. My dad didn’t think my brother and sister were geniuses, either. By his yardstick, none of us measured up to Einstein. Apparently, this was a great disappointment. Dad worried that this intellectual handicap would limit what we’d eventually achieve in life. Two years ago, I was fortunate enough to be awarded a MacArthur Fellowship, sometimes called the “genius grant.” You don’t apply for the MacArthur. You don’t ask your friends or colleagues to nominate you.
Instead, a secret committee that includes the top people in your field decides you’re doing important and creative work.
When I received the unexpected call telling me the news, my first reaction was one of gratitude and amazement. Then my thoughts turned to my dad and his offhand diagnoses of my intellectual potential. He wasn’t wrong; I didn’t win the MacArthur because I’m leagues smarter than my fellow psychologists. Instead, he had the right answer (“No, she’s not”) to the wrong question (“Is she a genius?”).

The 7 Habits of Highly Effective People
When I wrote this book in 1989, I had no idea how the world would change and that people would be able to read The 7 Habits of Highly Effective People in this amazing way on these amazing devices. Since then, this book has been called “the most influential business book of the century” (by The Wall Street Journal). It stayed on The New York Times best-seller list for five years. A “must-read” translated into 38 languages, with 20 million copies in print (and is arguably the most pirated business book in the world).

War Peace and International Security Jan Eichler
The ambition of this book is to fill a gap on the market with literature about war and peace during the one-hundred-year-long period between the beginning of World War I and the annexation of the Crimean peninsula. The book has been written with the aim to present this period in a new and consistent theoretical framework. To satisfy this aim, it was necessary to make a detailed study of a long range of theoreticians whose works and key ideas were used as good sources of inspiration. Among them, there are two giants with an enormous intellectual potential: Johan Galtung and Raymond Aron. The book is divided into five chapters. The first of them is dedicated to the articulation of the theoretical and methodological positions of the entire book. Its first part presents key theoretical inspirations. It commences with Johan Galtung and his theory of positive and negative peace, continues with Raymond Aron’s emphasis on diplomacy and strategy and concludes with Edward Carr and his distinctions between rational causes and historical accidental. His inspiration has been used for the periodization throughout this book.

Studies in Continental Thought
This book is a translation of Platon: Sophistes, which was published in 1992 as volume 19 of Heidegger's Gesamtausgabe (Collected Works). The text is a reconstruction of the author's lecture course delivered under the same title at the University of Marburg in the winter semester 1924-25. The course was devoted to an interpretation of both Plato, especially his late dialogue, the Sophist, and Aristotle, especially Book VI of the Nicomachean Ethics. It is one of Heidegger's major works, because of its intrinsic importance as an interpretation of ancient philosophy and also on account of its relation to Being and Time.
