The thesis proposes area classification after construction of datasets with pre-processing for Hyperion Hyperspectral, Operational Land Imager (OLI) and Advanced Land Imager (ALI) orthoimages. The techniques perform comparative analysis of Hyperion Hyperspectral, OLI and ALI orthoimages in terms of high Signal to Noise (SNR), spectral band configuration, technical superiority, improved system design and high radiometric resolution. The thesis further proposes criteria for selection of parameters like gamma parameter, penalty parameter, pyramid parameter and classification probability threshold to achieve higher classification accuracies of Hyperion Hyperspectral, OLI and ALI Satellite orthoimages by using Support Vector Machine (SVM), Spectral Angle Mapper (SAM) and Spectral Information Divergence (SID) classifiers. After performing the comparison, the thesis selects SVM as the most appropriate classifier in terms of overall accuracy, individual classes and the best orthoimagery i.e. Hyperion, OLI and ALI respectively. The thesis also presents application of classification accuracy assessment on Hyperion Hyperspectral, OLI and ALI orthoimages by using different classifiers i.e. SVM, SAM and SID. The thesis also proposes high accuracy based seasonal change detection analysis technique on Hyperion Hyperspectral, ALI and different datasets of OLI by using change detection matrix and difference maps. As a result of these contributions, 1x Journal and 6 x Conference papers duly peer reviewed have been published. The pre-processing of 242 bands of hyperspectral data results in 136 calibrated bands. Quick Atmospheric Correction (QUAC) are applied to Hyperion Hyperspectral and Fast Line-of-sight Atmospheric Analysis of Hyper cubes (FLAASH) are applied to OLI and ALI imagery respectively for atmospheric correction. Principal Component Analysis (PCA) is used for dimensional reduction of the hyperspectral data. PCA reveals that 99.94% of the hyperspectral data are contained in the first 15 Principal Components (PCs). Distinct spectral profiles are identified for all classes which are highly beneficial for feature identification and classification of images. Novel parameters are selected for high accuracy area classification in hyperspectral, OLI and ALI imagery via SVM, SAM and SID classification techniques. High accuracy based post classification change detection analysis is used on Hyperion Hyperspectral, ALI and different OLI datasets to produce difference maps which provide information not only about change of category but also type of change i.e. “from-to” of category of classes. Change detection matrix is also used which shows an overall decrease and increase of corresponding spatial extension of classes whereas diagonal elements of the change detection matrix show the unchanged pixels for the individual classes. The post classification technique is selected because of its ability for accurate change detection analysis of imagery of different sensors and its advantages over pre-classification methods that it compensates for variation in atmospheric correction and in conditions where the change is limited due to small rate of change. The results show that Hyperion hyperspectral and Landsat-8 OLI data achieved higher accuracies in mapping applications and high accuracy based post classification seasonal change detection analysis on different datasets on OLI results extraction of accurate change detection information as compared to previous Landsat satellite series.
ڈاکٹرشہزاد احمد کی نعتیہ شاعری نعت کی مختصر روایت عربی میں نعت کے معنی ’’وصف‘‘ کے ہیں لیکن اُردو میں اس کا استعمال حضور اکرم صلی اللہ علیہ و آلہٖ وسلم کی ستائش وثنا کے لیے مخصوص ہے۔(۱)اصطلاح میں ہر وہ نثر پارہ یا منظوم کلام جو رسول کریم صلی اللہ علیہ و آلہٖ وسلم کی مدح میں ہو نعت کہلاتا ہے، نعت گوئی وصف محمود کا دوسرا نام ہے۔ اس بارے میں ڈاکٹر رفیع الدین اشفاق رقم طراز ہیں: ’’نعت کے معنی یوں تو وصف کے ہیں لیکن ہمارے ادب میں اس کا استعمال مجازاً حضرت رسول سیدالمرسلین صلی اللہ علیہ و آلہٖ وسلم کے وصف محمودو ثنا کے لیے ہوا ہے جس کا تعلق دینی احساس اور عقیدت مندی سے ہے۔‘‘(۲) نعت کا آغاز اللہ رب العزت نے خود کیا اور انبیاء ورُسل کو نبی آخر الزماںصلی اللہ علیہ و آلہٖ وسلم کی آمد کی نوید سنائی۔ پھر قرآن مجید خود رسول کریم صلی اللہ علیہ و آلہٖ وسلم کے اوصاف حمیدہ اور سراپامبارک کے بیان سے مزین ہے۔ یہ سلسلہ قبل ازاسلام سے جاری ہے۔ تبع حمیری جو شاہ یمن تھا، اُس کے اشعار زبان زد عام ہیں ۔ راجا رشید محمود کے مطابق: ’’اولین نعت کی حقیقت یہ ہے کہ ہمارے آقا و مولاصلی اللہ علیہ و آلہٖ وسلم کے اولین نعت گو تبان اسعدبن کلی کرب تھے جنھیں تبع، شاہ یمن کہا جاتا ہے اور وہ حضورصلی اللہ علیہ و آلہٖ وسلم سے کم ازکم سات سو سال پہلے ہوئے ہیں۔‘‘(۳) بعدازا سلام عرب میں پہلی نعت جناب ابوطالبؓ نے سردارانِ قریش کے سامنے کہی۔ یہ نعت قصیدے کی صنف میں تھی۔ اس کے بعد حضرت حسان بن ثابتؓ، عبداللہ بن رواحہؓ، کعب بن مالک انصاریؓ اور کعب بن زہیرؓ کاروان نعت کے وہ خوش نصیب شعرا ہیں جنھوں نے حیاتِ رسولؐ...
Allah selected Muhammad ﷺ trained by wahi provided it with all the knowledge required for any creation. Either it is any kind of Science, engineering, medical, war strategy, defense plan or any known/Unknown direction of human guidance. At last one must have to say that any precise or authentic yield of the research/effort just turn the page of Hadith or a verse of Quran no more than this. The war strategy of Muhammad ﷺ is wondering throughout the world even in such an advance time, mostly is depends upon. Initially Muhammadا started journey with the preaching of Islam, people were expecting it is too poor. How will be fruitful. It is help of Allah, constant efforts & strategy that prove whole story. This world became more stay able and more secure, was never before in the history of the mankind. Now in this age deviation from the way of Muhammadا will bring the world closer to an irreversible explosion, all the Muslim/Non-Muslim collectively believe in.
The study aims to contribute to the previous studies by providing evidence regarding the relationship of working capital management and corporate performance in the financially constrained and unconstrained firms. A sample of 188 manufacturing firms listed on Karachi Stock Exchange Pakistan was selected for the time period of 2006 to 2014. The return on asset was used to measure the corporate performance while the working capital management was measured using the net trading cycle. The control variables used were operating cash flow, debt, fixed asset to total asset ratio, size and growth of firm. The findings of the study show that there exists a negative significant relationship between the net trading cycle and the return on asset. This means that a low level of working capital decrease the corporate performance. The firms were further segregated on the basis of size and debt to group the firms as financially constrained and unconstrained. No significant relationship of a low level and a high level of working capital with the corporate performance is found in the financially constrained firms. Further, the findings of the study show that in the financially constrained firms, the investing policy has a positive significant relationship with the return on asset, and the firms financing policy has a negative significant relationship with the return on asset. It is suggested that the manufacturing firms in Pakistan may efficiently manage their working capital in order to enhance the firm?s value and to attract more investors.
