دیوانِ یونس فریدی
حمد و نعت
صد شکر سوچ میری بھی تبدیل کچھ ہوئی
صد شکر میرے دل کو بھی ارمانِ نعت ہے

حمد
وہ ہے قادر، نہیں ہے اس میں کلام
اُس کے محتاج سب خواص و عوام
وہ سجھائے کمال کی جہتیں
ہے نا! انسان ہر لحاظ سے خام
جا رہا ہے ہر ایک مر کر بھی
باندھ کر جسم پر سفید احرام
ڈھانپ لے گی گناہ گاروں کو
رحمتِ ذوالجلال والا کرام
اے خدائے کریم! یونسؔ پر
رہے قائم سدا ترا انعام
نعت
منبعِ جود و سخا ہے، اُنؐ کی ذات
بے نواؤں کی نوا ہے اُنؐ کی ذات
اُنؐ کی آمد پر ہوا حق کا ظہور
مظہرِ نورِ خدا ہے اُنؐ کی ذات
امتوں میں اُنؐ کی امت ذی وقار
تاج دار انبیا ہے اُنؐ کی ذات
دیدہ ور ہو، آزما کر دیکھ لو!
آج بھی جلوہ نما ہے اُنؐ کی ذات
کیا کرے یونسؔ کوئی اُنؐ کی ثناء
عقل سے بھی ماورا ہے اُنؐ کی ذات

آمدِ خیرالوریٰ، صد مرحبا
خود خدا محو ثنائ، صد مرحبا
نعت گوئی میں ہمارے مقتدی
طائران خوش نوا، صد مرحبا
جن و انساں وجد میں ہیں اک طرف
اک طرف ارض و سما، صد مرحبا
ہے فرشتوں کی زباں پر آج بھی
مرحبا صلی علی، صد مرحبا
ز
اگر درپیش کوئی مسئلہ ہو
نظر سوئے درِ خیرالوریٰؐ ہو
اجل بھی رشک سے دیکھے گی مجھ کو
زباں پر اُس گھڑی یا مصطفٰےؐ ہو
ملے اِذنِ زیارت، اور پھر
وفور شوق میں دل...
This research is conducted, in order to analyze the students’ academic performance at secondary school level in Pakistan. This is a case study conducted in Hyderabad Division of Sindh Province in Pakistan. The study was focused to the students who have passed matriculation class (Class-X), equivalent to secondary level in Pakistan(10 years of education). Sample size of 1097 higher Secondary level students were randomly selected from various colleges and schools in a way that around 150 students should take part in the survey from each institute. The sample selection was further divided on gender (Male = 448, Female = 648) and locale (Urban=455, Rural=641) basis. A data collection questionnaire was developed by the researchers and implemented for data collection. After collection of the data from desired population, the statistical analysis based on Pearson’s Chi-square and Correlation models were carried out in SPSS. The conclusion inferred from the data analysis of the study, strongly revealed that the students’ academic achievement at high school secondary level was highly associated to their parent’s educational level and socio-economic background. Therefore, it is strongly recommended financial condition of the population must be enhanced by taking appropriate measures. In order to coup tough financial conditions at their homes, deprived students should be provided adequate scholarships. Free stationary and books should also be provided at schools.
Determination of the size of a defect in a given material is important from industrial usage point of view. In this work, a computational technique has been developed that takes a humble step forward from just qualitative description of defect, such as “big” or “small” to its area-wise quantification. Our program (by the name “DEFAREA”) accepts a 2D grayscale image of an investigated specimen as input and sizes the irregular shaped defects contained therein in terms of the area occupied by them. In case where a defect feature is of regular shape being a projected image of a cylinder or a sphere the program is also able to produce volumetric results. The program exploits the fact that defects offer color contrasts that are different from the rest of the image (such as bone fracture in X- ray radiograph). It is based on grayscale thresholding (GT) whereby it first iterates down to compute a minimum value of graylevel that separates the first peak from the rest of the distribution in the grayscale spectrum of the given input image. This threshold, which is representative of a particular shade of gray color, is then used to identify, select and count the number of pixels which have graylevel values below the computed threshold. The number of segmented pixels within the whole image size then easily produces not only a numeric fraction of the defective portion of inspected specimen but also the area occupied by the defect if the physical sizes and dimensional measurements of the specimen are known. The main part of the algorithm, however, revolves around devising a reliable computational method to obtain a certainty range in the reported defect size. Certainty range is needed as there physically exists a transition region (TR) between the defective and the immaculate parts of the investigated object that can not be put in either category. TR offers lesser contrast with the flawless part of the image than the pure defect areas. So a given defect is doubly quantified with and without appending the transition region around it with the aid of user-defined adjustability in the computed grayscale threshold. Then finally an average value of defect size is calculated along with an associated certainty. The presented algorithm is validated against physical measurements of some locally fabricated metallic plates having drilled holes of known sizes simulated as defects in them in which the results indicate that it correctly selects and quantifies at least 94.7% of the actual required regions of interest in a given image and it gives less than 8% false alarm rate. The algorithm is then applied to sizing of a wide range of defects commonly encountered in nuclear industry regarding reactor fuels. The images of nuclear fuels used as input in the program are collected from a reference standard source of neutron radiographs. The present work confirms the ability to quantify various kinds of defects such as chipping in nuclear fuel, cracks, voids, melting, deformation, inclusion of foreign materials, heavy isotope accumulation and non-uniformity etc. The classes of fuel range from those of research and power reactors to fast breeders, from fresh nuclear fuel to post-irradiate, and from pellets to annular and vibro-compacted fuel. It is also demonstrated that the program can handle a variety of image sizes, displays several output modes of image segmentation and works well without the need of any smoothening or eroding morphological operations.
