کچھ کتاب اور صاحب کتاب کے بارے میں
نذیر متین سے میرا تعلق نصف صدی سے زائد عرصے پر محیط ہے ۔بچپن کے معصوم ایام سے لے کر بڑھاپے کی دہلیز تک بہت سا سفر اکٹھے گزارنے کی وجہ سے ایک دوسرے کی مزاج شناسی بھی درجہ کمال کو پہنچی ہو ئی ہے زمانہ طالب علمی سے آ ج تک زندگی کی بہت سی راہوں پر اکٹھے سفر کیا اس لیے دیگر دوستوں کی رائے ہے کہ نذیر متین کو جتنا میں جا نتا ہوں دوسرا اور کوئی نہیں کسی حد تک یہ بات درست بھی ہے میں ان کے مزاج ،خیالات اور سیاسی و سماجی نظریات کو نہ صرف جا نتا ہوں بلکہ خود بھی حامی و معترف ہوں ۔
ان کے اندر قدر نے کچھ ایسی خوبیاں رکھی ہیں جو آج بہت کم لوگوں میں پائی جاتی ہیں ۔کلمہ حق کہنا رزق حلال پر یقین رکھنا اپنے اور اپنے خدا پر مکمل یقین رکھنا پسے ہوئے اور مجبور لوگوں کی آواز سننا اور ان کی آواز بننا اور خاص طور پر اپنے نظریات پر قائم رہنا ان کی شخصیت کے وہ پہلو ہیں جنھوں نے اس کی ذات کو باوقار بنایا ہوا ہے ۔
زندگی کو بڑے قریب سے دیکھنے والا نذیر متین خوب جانتا ہے کہ خوشی کسے کہتے ہیں اور غم کیا ہو تا ہے گھر کیسے آ باد ہوتے ہیں ،بستیاں کیوں اجڑتی ہیں ؟بھوک کیا ہے ؟زندگی کی راحتیں کیسے ملتی ہیں اور مفلسی چہروں کو کیسے بگاڑتی ہے کسی کے جنازے میں کم سے کم یا زیادہ لوگوں کی شرکت کیا معنی رکھتی ہے ۔مزدوروں ،محنت کشوں ،طالب علموں اور سیاسی کارکنوں کی جدو جہد کن کن مراحل سے گزرتی ہے اور ضروریات زندگی کی افراط اور کمی کے کیا نتائج نکلتے ہیں ۔ان کی چالیس سالہ صحافتی زندگی...
Allah Almighty has kept many sources to save his eternal message, of writings the in biography holy his and صلى الله عليه وسلم prophet his of words golden the different scholars. This shows the importance of our sacred heritage that includes the biography of the Holy Prophet ﷺ. These hand-written books (manuscripts) consist of the exegesis of Qur’ān, Jurisprudence, Principles of Exegesis of Qur’ān and Jurisprudence, morphology, syntactic and many other sciences related to Arabic language and literature. The researcher has صلى الله عليه وسلم Prophet Holy the of biography the about manuscripts the evaluated written in different universities of Pakistan during MA, MPhil, and PhD in the 20th century. The research methodology followed in the research is descriptive. Each understudy manuscript is considered from different aspects that include different features of the work done, i. E. Language of the manuscripts, details of the original text, references of Aḥādīth, pattern of footnotes, primary and secondary sources etc. The article is divided into three main sections in the following way: First deals with Islamic Arabic Manuscripts, Second are Manuscripts in Pakistani Libraries and third are would research The. صلى الله عليه وسلم Prophet the of Sirah about Manuscripts evaluated highlight value of the Manuscripts and the critical analysis of the mistakes found in Manuscripts and it would certainly improve their language, and research pattern.
In recent years, the evolution of technology has broadened the avenues of information sharing. The volume of sensitive and important information being exchanged over the insecuremediumhasincreaseddramatically. Ellipticcurvecryptography(ECC)hasbecomewidelyacceptedasanefficientmechanismtosecureprivatedatausingpublic-key protocols. The pivotal operation within ECC based crypto-systems is scalar point multiplication which is computationally expensive. Point multiplication can be achieved by iterative execution of point addition and point doubling groups operations which in turn are based on finite field arithmetic operations such as addition, subtraction, multiplication and division. These finite field arithmetic operations, especially the finite field multiplication are the bottleneck of any ECC based crypto-system. To reduce the computational cost of point multiplication operation, by optimizing these finite field arithmetic operations, is an active area of research. Efficient hardware implementations of Elliptic Curve Point Multipliers (ECPM) over several new platforms have been in the focal point of major research efforts for the last two decades. Field Programmable gate arrays (FPGA) due to its reconfigurable nature and less development time has become a very popular choice for hardware implementationofcryptographicalgorithms. ECPMarchitecturesonFPGAeitheronlyuseLook Up Tables (LUTs) or have utilized embedded Digital signal processing (DSP) blocks along with the LUTs. LUTs-only based designs are portable designs since they can be translated to any FPGA family or standard cell based Application Specific Integrated Circuits(ASIC).However,existingLUTsbaseddesignsareslowersincetheyarebased on finite field arithmetic components which have longer critical path delay and higher clock cycles consumption. DSP based ECPM designs may offer better performance at the cost of increased area. However, DSP based designs have portability issues. The prime objective of this dissertation is to design LUTs based high speed ECPM architectures. ThebottomlayerFp arithmeticoperationsespeciallytheFp multiplication are first optimized at both circuit level and architectural level. Subsequently, based on these optimized finite field arithmetic primitives, and by devising an efficient schedul ing strategy for elliptic curve group operations, this dissertation achieves high speed hardware architectures to perform elliptic curve point multiplication. Inthefirstcontribution,anovelhighspeedRedundant-Signed-Digit(RSD)basedECPM architecture for arbitrary curves over a general prime field is designed. It is based on a new high speed finite field multiplier architecture which employs different parallel computation techniques at both circuit level and architectural level. As a result of these optimizationstrategies,theproposedmultiplieroffersasignificantreductionincomputation time over the state-of-the-art. An efficient scheduling strategy is devised for PA andPDgroupoperationswhichreducedtherequirednumberofclockcyclesforECPM design. The ECPM architecture designed in this dissertation offers higher speed and lower area-time product than recent state-of-the-art ECPM designs. In the second contribution of this dissertation, an ECPM architecture for low area applications is developed. The ECPM design utilizes fewer resources while maintaining the competitive speed with other state-of-the-art ECPMs. The finite field multiplier developed in this dissertation offers lower area-time product than recent contemporary designs. Basedonthisfinitefieldmultiplierandapipelinedfinitefieldadder/subtractor, an ECPM architecture is designed that offers lower area-time product than recent stateof-the-art ECPM designs. The third contribution presents a high speed ECPM architecture for National Institute of Standards and Technology (NIST) recommended primes. Different strategies such as RSD representation, segmentation and pipelining are used to reduce the critical path delayandrequirednumberofclockcyclesforthefinitefieldarithmeticprimitives. The implementation results demonstrate that the proposed ECPM architecture outperforms other state-of-the-art designs in terms of speed and area-time product metrics. Finally, an ECPM architecture for the Curve448 is developed in the last contribution of this dissertation. Curve448 is recently recommended by the Internet Engineering Task Force (IETF) for future cryptography. The only existing ECPM architecture over the Curve448isaDSPbaseddesignandlacksportability.

A comparison with the state-of-the-art ECPM designs shows that ECPM design in this dissertation provides higher speed and can be adopted in time-critical applications.
