Mathematic`s Blog

Alhamdulillah, ternyata bikin blog ada manfaatnya. Sebenarnya waktu pertama buat blog cuma pengen berbagi informasi aja sama yang laen. Habisnya gara2 keseringan ngenet & cari referensi Jurnal, artikel Dll. Aq jadi bingung buat nyimpen filenya, he... he.. soalnya Hard Drive komputeq maih kecil.... Eh ... ga ku sangka, ternyata selain bs ngumpulin jurnal2, aq juga dapat kenalan banyak. Buat temen2 pengunjung bloggq, thanks yah... kalo perlu kasih masukkan biar aq jadi tambah mahir ngurus bloggq.

Numerical solution of duct flows of multiple visco-plastic fluids M.A. Moyers-Gonzaleza∗, I.A. Frigaarda,b a Department of Mathematics, University of British Columbia, 1984 Mathematics Road, Vancouver, BC, Canada V6T 1Z2 b Department of Mechanical Engineering, University of British Columbia, 2324 Main Mall, Vancouver, BC, Canada V6T 1Z4 Received 31 July 2003; received in revised form 13 November 2003; accepted 15 December 2003 This article is part of a Special Volume containing papers from the XIIIth International Workshop on Numerical Methods in Viscoelastic Flows ====================================================================== Abstract We consider numerical solution of duct flows of multiple visco-plastic fluids using both regularisation techniques and the augmented Lagrangian method. Using single fluid test problems, we demonstrate that there are certain classes of problems for which the augmented Lagrangian method is superior. These problems include those of determining the c...

Plug flow and the breakdown of Bagnold scaling in cohesive granular flows Robert Brewster,1 Gary S. Grest,2 James W. Landry,3 and Alex J.

Received 5 September 2005; published 21 December 2005 Cohesive granular media flowing down an inclined plane are studied by discrete element simulations. Previous work on cohesionless granular media demonstrated that within the steady flow regime where gravitational energy is balanced by dissipation arising from intergrain forces, the velocity profile in the flow direction scales with depth in a manner consistent with the predictions of Bagnold. Here we demonstrate that this Bagnold scaling does not hold for the analogous steady flows in cohesive granular media. We develop a generalization of the Bagnold constitutive relation to account for...

Beyond Probability GOD'S MESSAGE IN MATHEMATICS by ABDULLAH ARIK FOREWORD This discussion would be unprofitable if it did not lead us to appreciate the wisdom of our Creator, and the wondrous knowledge of the Author of the world, who in the beginning created the world out of nothing and set everything in number, measure and weight, and then in time and age of man formulated a science which reveals fresh wonders the more we study it . Hrovista of Gandersheim (980 AD) All of us, at one time or another, have been compelled to contemplate creation. Questions such as the purpose of our lives and the existence of God, have been pondered upon from time immemorial. There have always been those who choose to interpret the harmony and order of the cosmos as a fluke of nature, but a closer look gives clear evidence of a design, and thus a designer. The discoveries being made on all frontiers are making this picture clearer by the day. Most contemporary scientists are a...

Water has a very important message for us. Water is telling us to take a much deeper look at our selves. When we do look at our selves through the mirror of water, the message becomes amazingly, crystal, clear. We know that human life is directly connected to the quality of our water, both within and all around us. The photographs and information in this article reflect the work of Masaru Emoto, a creative and visionary Japanese researcher. Mr. Emoto has published an important book, "The Message from Water," from the findings of his worldwide research If you have any doubt that your thoughts affect everything in, and around you, the information and photographs that are presented here, taken from the book of his published results, will change your mind and profoundly alter your beliefs, .From Mr. Emoto's work we are provided with factual evidence, that human vibrational energy, thoughts, words, ideas and music, affect the molecular structure of water, the very same water...

1. As far as the Creator (whose proper name is Allah) is concerned, you will be able to identify Him and get to know Him, His role and your relationship to His names, you will be able to communicate with Him any time, 24 hours a day, throughout the whole year. As a result of this category, you will be able to know your origin, your roots and the wisdom as to why you are on this planet. You will be able to have good answers to the questions why, how, when, where, what and other philosophical questions. 2. As a result of the first benefit, your loyalty, allegiance, and obedience will be to the Creator himself. You will transcend yourself from all types of allegiance for this world. This means that if there is a conflict of interest between your boss, your job, your government, your system or any worldly relationship with the Creator, you will undoubtedly put your trust in Allah, the Creator of the universe. You will follow Him before you follow anyone else. 3. As a result of the secon...
