Breast cancer is considered to be one of the most fatal types of cancer among women. The early detection of breast cancer increases the survival probability. Computer Aided Diagnosis (CAD) system for detection and classifying of masses in mammograms is essential. In this thesis, new pre-processing techniques for mammograms have been proposed. First, an improved segmentation technique using image pre-processing and modified reaction diffusion based level set method is developed. The mammogram is passed through morphological operations, contrast enhancement and interpolation algorithm. The pre-processed image is then passed through a modified reaction diffusion based level set algorithm for accurate breast boundary segmentation. In Second pre-processing technique, pectoral muscle is suppressed by the proposed technique based on geometry and contrast variance between the breast tissues and pectoral muscles. Simulation results verify the significance of proposed schemes visually and quantitatively as compared to state of art existing schemes. Three class classification based on deep learning techniques i.e. CNN and RBMs is proposed. In the CNN-DW method, enhanced mammogram images are decomposed as its four subbands by means of two-dimensional discrete wavelet transform (2D-DWT), while in the second method discrete curvelet transform (DCT) is used. Proposed methods have been compared with existing methods in terms of accuracy rate, error rate, and various validation assessment measures. Simulation results clearly validate the significance and impact of our proposed model as compared to other well-known existing techniques. Last but not the least, a novel three-class classification technique for a large dataset of mammograms using a deep-learning method of restricted Boltzmann machine (RBM) is proposed. The augmented dataset is generated using mammogram patches. The dataset is filtered using a non-local means (NLM) filter to enhance the contrast of patches. These patches are decomposed using (2D-DWT) and (CT). The proposed method is compared with existing methods in terms of ROC curve, accuracy rate and various validation assessment measures. The simulation results clearly demonstrate the significance and impact of our proposed model compared to other well-known existing techniques.

 معاشرتی جرائم اور ان کی سزاؤں کا تعین ہر انسانی معاشرہ اور ریاستی نظام کی ضرورت ا ور ذمہ داری رہی ہے اور ہر دور میں مختلف حوالوں سے اس پر علمی ا ورتحقیقی کام ہوتاآ رہاہے۔ اسلامی ریاست کی بنیاد آسمانی تعلیمات کے حوالے سے شرعی احکام و قوانین پر ہوتی ہے اور اس کی ابتدا حضرت آدم و حوا علیہما السلام کو زمین پربسانے کے ساتھ ہی اللہ رب العزت نے ان سے اور ان کی نسل و ذریت سے اس ارشاد کے ساتھ فرمادی تھی کہ

﴿فَإِمَّا يَأْتِيَنَّكُمْ مِنِّي هُدًى فَمَنْ تَبِعَ هُدَايَ فَلَا خَوْفٌ عَلَيْهِمْ وَلَا هُمْ يَحْزَنُونَ﴾[البقرہ، 38:2 ]

دنیا میں زندگی بسر کرنے کے لیے میری طرف سے تمہارے پاس ہدایات آتی رہیں گی اور ان پر عمل کرکے تم خوف و حزن سے نجات پا سکو گے۔ یہ ہدایات حضرات انبیاء کرام علیہم السلام کے ذریعہ مسلسل نازل ہوتی رہیں جن کا آخری اور مکمل مجموعہ قرآن کریم کی صورت میں ہمارے پاس بحمد اللہ محفوظ و موجود ہے۔ حضرات انبیا ء کرام علیہم السلام نے صرف ہدایات نہیں پہنچا ئیں بلکہ ان کی ضروری تعبیرات دتشریحات بھی فرمائیں اور ان پر عمل کا ماحول قائم کرکے ایک اسلامی معاشرہ کی عملی صورت بھی اپنے پیرو کاروں کے ساتھ رکھی جو ہمارے پاس حدیث و سنت کے ساتھ ساتھ تعامل صحابہ کرام با لخصوص خلفاء راشدین رضوان اللہ علیہم اجمعین کے کردار کی شکل میں قیامت تک کے لیے اسوہ اور راہنماکے طور پر ہماری ملی تاریخ کا اہم ترین حصہ ہیں۔

ان اصول و ضوابط کی سوسائٹی میں عملی تنفیذ و تطبیق کے وسائل و ضروریات کو فقہا ئے عظام رحمہم اللہ نے مرتب فرمایا اور ہر دور میں اس وقت...

Legal Authority of the Prophet Muhammad and the Orientalists: A Critical Study

Civic behavior reflects the values related to individual’s attitude towards family, peer group, and neighborhood and includes the way one behaves in the society and community as a whole. The purpose of the present study is to describe what civic behavior is, its characteristics, its status in the Hadith, and the way forward for improvement of the civic behavior as guided by Sīrah of the Holy Prophet (ﷺ). Study implies that truthfulness, mercifulness, polite talk, helping others, respect for others, caring and sharing and promise-keeping, loyalty, sympathy, honesty, kindness, brotherhood, cooperation, fairness and unity are the core qualities that make the individual a civilized and active citizen and our Holy Prophet (ﷺ) is the embodiment of all these virtues. Descriptive approach was followed to explain and analyze the concept. First the concept of civic behavior was interpreted, then its importance and characteristics were discussed. After that it was explored in the light of the teachings of the Quran and the Prophet Muhammad (ﷺ). The findings highlight that the civic behavior in its best form was preached and practiced by the Holy Prophet (ﷺ) and his companions. Each dimension was interpreted in the light of the Quran and the Sīrah. It was concluded that Sīrah of the Holy Prophet (ﷺ) is an immaculate source of guidance and inspiration for not only Muslims but also for the whole mankind in acquiring the core values and abilities that determine the Civic behavior of an individual which ultimately results into a well-organized, peaceful and civilized society The study suggests that civic behavior of the citizens has significant impact on the formation and development of a peaceful society. It is recommended that civic behavior as reflected in the life of and practiced by the Holy Prophet (ﷺ) should be promoted and practiced for achieving a civilized social setup.

Regionalism in South Asia: Problems and Prospects for South Asian Association for Regional Cooperation A Case Study of India-Pakistan Attiude Towards Saarc

Regional cooperation has gained new significance in the context of the increased competition among the developed countries, rising protectionism and growing crisis in the international economic system. The dilution of the North-South dialogue and increasing emphasis on South-South cooperation also promoted the growth of regional cooperation in the recent times. One of such ventures of collective self-reliance and development is attempted by the states of South Asia which took the form of SAARC (South Asian Association for Regional Cooperation). Regionalism is as such a manifestation of particular regional arrangements in various economic, social, cultural and political groupings to facilitate regional cooperation. These regional associations are becoming effective, creating a new milieu for the political world as well as for economic interaction in a globalized world. Regional integration provides in a well-defined geographic region and techniques of conflict resolution and possibilities of pursuing common foreign policy objectives within a regional context. It also provides a mechanism for integration and unification leading to community building. However, the economic aspect holds the pre-eminent position for interdependence among the member countries in regional arrangement. South Asia is a complex region with striking similarities in social, cultural and ethnic aspects. There exist sharp differences in the political systems, economics, political, and strategic perception of the component states. While diversities divide these states, the similarities bring out their common heritage, common problems and common goals. This very complexity of this region witnessed a late and slow growth of the regional cooperation. SAARC, thus, has an unenviable task of achieving its objectives in a region that is never free from internal conflicts and tensions. Regionalism has become substantial phenomenon in international relations in Post-World War II period. The era of 1950s and 1960s saw the rise of many regional groupings in different areas of the world. After the Cold War regionalism obtained a transformed motivation with the thrust of globalization. It enhanced the development of interdependence and provided more incentive to the process of globalization. Subsequently, late 1980s the process of regionalization began to reemerge in different areas of the world and this process coincided with the rise of globalization. xi Regionalization and globalizations both led to integration but these not essentially supplement nor contradict each other and both operate at different levels. This dissertation is an attempt to highlight the politics of regionalism in South Asia and to focus on the role of SAARC (South Asian Association for Regional Cooperation) in the region. India and Pakistan‟s hostile relationship remained main obstacle in the progress of SAARC. Despite having several bilateral problems SAARC provides regional identity and discourse to small countries of South Asia. Furthermore, this study will explain all factors which are contributing in regionalism in South Asia. Against this background, the present study tries to probe the salience of regionalism in South Asia. It is an attempt to understand problems and prospects of SAARC. The various factors that influence regional cooperation in South Asia and the smooth functioning of SAARC and a case study of India and Pakistan‟s attitude towards the regional arrangement is being discussed. The present study is also intended to be an inquiry into the complexity of international and intra-regional forces that create challenges as well as opportunities for regional cooperation in South Asia. Therefore, this study focuses on the political factors that influence SAARC rather than, highlighting areas of cooperation. Underlying assumption is SAARC primarily emerged due to political compulsions of South Asia. Regional cooperation could not take to a deeper level because there are still doubts about the political will and commitment towards regional cooperation on the part of the member states.
