With the growth of internet and advance in computing technologies, large volume of data is generated and processed on daily bases. The situation is very appealing for sophisticated tools and techniques to process and get the insight of such a large data ubiquitous in every domain. Classi - cation and pattern recognition is an important technique in data mining task tond unexplored knowledge within the data. Emerging Pattern (EP) based technique is used to discover an abrupt change in across the datasets. Emerging pattern based classi ers are very e cient innd- ing patterns inherently exist among the collection of large datasets in hand. Nevertheless, the discovery of emerging patterns is a challenging and non-trivial task due to the inherent complexity of datasets. More- over, in contemporary literature plethora of work is available tond a hidden emerging pattern. Among these techniques,tree-based approach is commonly utilized for the discovery of emerging pattern. However, a tree-based approach follows greedy search technique, su ers various limitations i.e. tree size grows with problem size up to the level where tree-based computation is not cost e ective. In this dissertation, a novel approach for discovering emerging patterns has been proposed. The pro- posed approach exploited Ant Colony Optimization (ACO) technique for the exploration of high quality emerging patterns in the classi cation problem. Furthermore, in contrast to the deterministic approach used in tree-based classi ers, the proposed probabilistic method provides com- petitive classi ers. The proposed approach is capable to e ciently avoid an exhaustive search of tree-based approach and obtain comparatively better accuracy to discover strong jumping emerging patterns. The pro- posed approach has been evaluated on various benchmark datasets for accuracy and robustness. Additionally, most of the classi ers are work with discrete data only and Discretization methods are used to change continuous data into discrete before input to a particular classi er. To evaluate the performance of proposed approach on di erent discretiza- tion methods several experiments are carried out to evaluate the robust- ness. Experimental results show that proposed approach provides better performance on di erent datasets in comparison with the state-of-the-art techniques.

سر شاہ سلیمان

سرشاہ سلیمان
نئی تعلیم نے جو بہتر سے بہتر نمونے ہماری قوم میں پیش کئے اُن میں سے ایک سرشاہ سلیمان تھے، وہ مشرقی تعلیم کے ایک ممتاز خاندان کے فرد فرید تھے، ان کا آبائی وطن ضلع اعظم گڑھ ہی کا ایک ممتاز قصبہ تھا، ملا محمود جون پوری جن کا نام شمس بازغہ اور فرائد کے مصنف کی حیثیت سے آفتاب کی طرح درخشاں ہے، ان کے مورثِ اعلیٰ تھے، سرسلیمان مرحوم نے بھی ابتدائی مشرقی تعلیم حاصل کی تھی، اور عربی تعلیم سے بہرہ ور تھے، ملا محمود نے فلسفہ میں ادب کی، اور ادب میں فلسفہ کی شان پیدا کی تھی، یہی خصوصیت سر سلیمان کی ذات میں تھی، ایک طرف وہ قصائد ذوق اور مثنویات میر کو ترتیب دیتے تھے اور دوسری طرف آئن سٹائن کے نظریہ پر نقد و تبصرہ کرتے تھے۔
سر سلیمان کی فطری ذہانت بے نظیر تھی، ذہانت کی بجلی ان کی رگ رگ میں بھری تھی، وہ نہ صرف ہائی کورٹوں کے جج رہے، بلکہ قانون کے نکتہ شناس بھی تھے، ان کی لیاقت و قابلیت کی شرح کے لئے چند سطریں کسی طرح کافی نہیں ہوسکتیں، اور ان سب باتوں کے ساتھ وہ مسلمان بھی تھے، ایماناً اور عملاً مسلمان! وہ ان تنگ ظرفوں میں نہ تھے جو رومن حروف کے چند الفاظ پڑھ لینے کے بعد اپنے کو حقائق و معارف کا سب سے بڑا عارف مان کر دین و مذہب سے بے نیاز ہوجاتے ہیں، اور بندگی کی حد سے آگے بڑھ کر خدائی کے عرش کا اپنے کو مستحق سمجھنے لگتے ہیں، مرحوم میں ان خوبیوں کے ساتھ بہت سی اخلاقی خوبیاں بھی جمع تھیں، وہ منکسر، متواضع، حلیم، اور سادہ مزاج تھے، ساتھ ہی اپنی رائے کے مضبوط اور کام کے دھنی تھے، وہ عالم تھے، مگر عمر بھر طالب العلم بنے...

Elisa Based Surveillance of Bovine Fascioliasis in District Sargodha

An excretory/ secretory antigen based ELISA was developed for diagnosis of bovine fascioliasis and evaluated in field survey in district Sargodha in comparison with coprological examination and commercial kit (DRG Diagnostica). The study was divided into three experiments. First experiment was slaughter house based epidemiology of bovine fasciolasis. Livers, bile ducts and fecal samples of 146 cattle and 184 buffaloes were examined for presence of Fasciola from slaughter house of district Sargodha. Significantly higher prevalence was found in buffaloes as compared to cattle in both coprological (χ2=25.312; P-value=0.0080) and fecal examination (χ2=17.453; P value=0.0001). By coprological examination, Fasciola eggs were detected in 29.89% (55/184) buffaloes and in 20.55% (30/146) cattle whereas 48.37% (89/184) buffaloes and 37.67% (55/146) cattle were found infected during liver examination. Sex was found to be non-significantly associated with risk of infection while negative association was found between age and occurrence of disease. Prevalence of disease was lower in higher age groups. In second experiment, development and standardization of ES antigen based ELISA was conducted. Adult Fasciola and blood samples were collected from 146 cattle and 184 buffaloes. Excretory/ secretory antigens were prepared by incubating adult Fasciola in PBS for 6-8 hrs and then filtering through 0.22 μm syringe filter. Then checker board titration was performed and optimum concentration of antigen and serum was determined and used in screening of all serum samples. Seroprevalence was found to be 50% and 38.35% in buffaloes and cattle, respectively. In house ELISA was found to be 100 % sensitive while specificity was 96.84% in buffaloes and 98.90% in cattle. In third experiment, serological and coprological survey of bovine fascioliasis of district Sargodha was carried out. A total of 600 blood samples and 5580 fecal samples were collected from all six tehsils of district Sargodha. Sedimentation- floatation technique was adopted to identify Fasciola egg in feces. Sera were screened for presence of antifasciola antibodies by indigenous ELISA kit and DRG kit. Both kits were equally sensitive while indigenous ELISA was more specific. The highest prevalence was found during month of December in both serological and coprological examination. Higher prevalence was recorded in tehsil Bhalwal, Sahiwal and Shahpur as compared to Sargodha, Kot-Momin and Silanwali. Risk of fascioliasis was found to be negatively associated (OR=1.181; χ2=105.6757; P-value <0.0001) with age categories, highest prevalence of fascioliasis in >2-4 years age group and then decreasing with advancing age. Sex was found to be non-significantly associated with disease. As for managemental practices are concerned, higher prevalence was found in grazing group (χ2=61.3443; P-value <0.0001), pond watered and river watered group (χ2=89.7096; P-value <0.0001) as compared to stall feeding and tap watered group.
