مولانا مفتی محمود احمد نانوتوی
افسوس! گزشتہ مہینہ ہمارے شبستان دارالعلوم دیوبند کے دو اور روشن چراغ بجھ گئے۔ مولانا مفتی محمود احمد صاحب نانوتوی ناتوتہ کے ایک اعلیٰ اور شریف خاندان کے فردِ فرید تھے۔ تعلیم دیوبند میں پائی تھی، اولاً حضرت شیخ الہند اور پھر حضرت الاستاذ مولانا محمد انورشاہ الکشمیری سے خاص استفادہ کیااوران سے تلمذ خصوصی کاتعلق رکھتے تھے ۔علم وفن کی پختہ استعداد وزہد وورع اوراخلاق فاضلہ، یہ تینوں اوصاف بزرگان دیوبند کے امتیازی کمالات تھے۔ مفتی صاحب بھی ان کے جامع تھے ۔لیکن انھوں نے فقہ اورحدیث کواپنا خاص فن بنالیا تھااور ان میں ان کی نظر بڑی دقیق اور غامض تھی۔ایک عرصہ سے اجین میں قیام پذیر تھے۔وہاں کی مسلم اورغیرمسلم آبادی کوانھوں نے اپنے علم وفضل اور کردار سے کس درجہ عقیدت مند بنالیا تھااس کااندازہ اس سے ہوگا کہ جب ان کا جنازہ اٹھاہے تو تنگیِ وقت کے باوجود کم وبیش پندرہ ہزار آدمی اس کے جلوس میں تھے اور ان میں جن سنگھی بھی تھے ۔ دارالعلوم کی مجلس شوریٰ کے دیرینہ رکن تھے اور اس کی ہر ممکن خدمت کواپنا فرض سمجھتے تھے۔ حضرت شاہ صاحب سے عقیدت کیا ان کے نام کے عاشق تھے۔مجلس میں جب کبھی حضرت الاستاذ کاذکر چھڑ جاتا تو دوسروں کی باتیں بڑی توجہ اوردل چسپی سے سنتے اور پھر جب خود بولنا شروع کرتے توعالم ہی عجیب ہوتا جس کو سن کردل ودماغ دونوں روشن ہوجاتے تھے۔ رحمہ اﷲ رحمۃً واسعۃ۔

Aim To explore the apparent lack of personal concern for the welfare of others in China? To develop concepts to understand this social phenomena in natural settings using ethnographic and participatory research. Research Question How can the knowledge derived from qualitative research be used to improve the welfare of the poor in Shanghai? Ethics The study was carried out within the guidelines of the declaration of Helsinki. The study was characterised by anonymity, beneficence, non maleficence, and the maintainence of the dignity of participants Method Collection of data. The principle data source was “observation” spot observation”(Baksh 1990)”, participant observation”(Hammersley and Atkinson 1983)vignettes(Finch 1987, Sani Bin Gabi 1990), oral history(narrative) Conclusion The study was conducted ethically. It was a worthwhile study attempted to deal with current problems. The publication of this paper can be used to stimulate further enquiry into the problem of those in need of social welfare in Shanghai and China, in the hope it will improve services where they are needed. Suggested solutions In a country where intergenerational family ties are so strong and “guanxi” exists it is paradoxical there is little empathy for others. Confuscian values, changed family beliefs, and education at school and university may assist in increasing empathy. Learnt conditioning, to ignore or dissociate, from another human being in need of help, can be slowly overcome by implementing universal and improved changes in societal living conditions. This can be achieved by improving social welfare programs, spearheaded by a compassionate government. There is a view that it is an egregious and transparent fiction, to promulgate and publically promote, the philosophies and policies of communism, yet allow these curable social ills to remain. ”Rex ipsa Loquiter”. The healthy should help the sick, the rich should help the poor and the employed should help the unemployed, Proportionately, in accordance with what they have they should give. The promotion of a “ forward thinking, humane, listening and open society, rather than a closed, narrow, opaque, inward looking “weltanschaung” would assist societal reform. We “bystanders”, we must all try to imagine we are in the place of those in need, and feel aas they do, in their situation. We must follow the advice of Mencius (372-289BC) and develop and use “empathy” As Mencius said, ”a developed human heart is the basis of a moral life”
A high performance algorithm for the implementation of Arbitrary Lagrangian and Eulerian (ALE) moving mesh scheme for both 2D and 3D Fluid Structure Interaction (FSI) problems for the shared and distributed memory systems is discussed in the the- sis. OpenMP library is used to implement parallel programs on shared memory systems whereas message passing interface (MPI) is employed to write parallel programs on dis- tributed memory systems. Moving mesh techniques are the integral part of a wider class of fluid mechanics problems that involve moving and deforming spatial domains, namely, free-surface flows and FSI. The moving mesh technique adopted in this work is based on the notion of nodes relocation, subjected to certain evolution as well as constraint conditions. A conjugate gradient method augmented with a preconditioning is employed for the solution of the resulting system of equations. The proposed algorithm, firstly, re- orders and partitions the mesh using an efficient divide and conquer approach and then parallelizes the ALE moving mesh. Different mesh partitioning algorithms are discussed, which include the octree method, and k-way graph partitioning technique using Parmetis library. Numerical simulations are conducted on AMD Opteron and Intel Xeon processors, and unstructured triangular and tetrahedral meshes are used for the 2D and 3D prob- lems. The better results, in terms of the speedup, are obtained for the shared memory system than the distributed memory system for both the 2D and 3D problems. The quality of meshes is checked by comparing the element Jacobians in the reference and current meshes, and by keeping track of the change in the interior angles in triangles and tetrahedrons. The proposed parallel mesh reordering algorithm using sampling approach for work load re-distribution concluded 51% of average efficiency in term of the speedup for shared memory systems. The overall maximum speedup of 6.37, for the shared mem- ory system, is achieved using eight processing elements (PEs) as compared to 4.11 for the distributed memory system including twelve PEs. As a case study, the thesis also discusses the high performance implementation of a stabilized mixed finite element method for Darcy flow using MPI library. It has a lot of practical applications in the field of petroleum engineering and earth sciences especially, where the flow of fluid is of interest in a permeable porous medium. The maximum speedup of 12.24 is achieved using 28 PEs by incorporating the proposed mesh partition- ing algorithm. Outline Chapter 1 defines and introduces the problem statement and Chapter 2 gives the gen- eral introduction of the thesis. Chapter 3 presents the literature review of ALE moving mesh generation, stabilized mixed finite element methods, k-way graph partitioning algo- rithm and tree based spatial data structures. Chapter 4 mathematically formulates the ALE mesh generation problem and presents the serial algorithm for optimization using the preconditioned conjugate gradient method. Chapter 5 presents a mesh reordering algorithm based on quadtree/octree and quick sort techniques. Chapter 6 discusses the parallelization part of mesh reordering algorithm based on a sampling approach and also discusses the experimental results for the shared memory systems. Detailed discussion about the mesh partitioning and experimental results using MPI are given in Chapter 7. Chapter 8 briefly describes the stabilized finite element method for Darcy Flow and dis- cusses the results of 2D problems for a distributed memory system. Finally, conclusions are drawn in Chapter 9 and future work is presented in Chapter 10.
