The document summarizes information about angels from Islamic sources. It discusses that angels have physical bodies and wings, are always obedient to Allah, and have various functions including breathing souls into bodies and removing souls at death. It mentions five angels specifically - Jibril, Meekaeel, Haroot, Maroot, and Malik. It describes the process of souls being taken by angels at death for believers and non-believers. It also notes there are recording angels, 19 angels guarding Hell with Malik as its gatekeeper, and four angels accompanying each person.
Biomechanics and high performance sport. Biomechanics is the study of forces on living organisms. High performance sport involves athletes, coaches, and administrators working to continually improve athlete performance through best facilities, services, and focus on athlete needs. Biomechanics can offer analysis of technique deficiencies to identify training needs and improve performance.

The document discusses several important issues relating to the way of Muslims. It addresses the proper dawah style (tough vs easy vs educational), attitude (humble vs arrogant), and what brings unity among Muslims (Tawheed and Quran/Sunnah vs other things). Maintaining the right approach in these areas is vital to guiding people to the straight path.

The document provides an introduction to the Islamic Online University's Da'wah Training course. It discusses three arguments for why Islam is the true religion of God. First, the name "Islam" means submission to God and was revealed by God, unlike other religions whose names were given later. Second, Islam teaches a simple relationship between God, humanity and creation - that only God alone deserves worship. Third, Islam's teachings are universally applicable to all people at all times. The document explores these concepts to support Islam's claim of being the true religion.
The Shaikh provides advice to students of knowledge and youth facing ideological confusion. He advises (1) fearing Allah and avoiding speech that causes harm, (2) seeking rectification and unity among Muslims, and (3) learning Islam from credible scholars following the Quran, Sunnah, and righteous caliphs. True knowledge comes only from studying under sincere scholars well-versed in Islamic texts and teachings, not from those ignorant of Islam or pushing their own ideas. Students should adhere strictly to the way of the Prophet and early Muslims to avoid misguidance and division.
The Second Annual National-level Mathematics Talent Program for High School Students
Objective: To search and mentor young Mathematical talent (age group 13-15) in the country. Guide them to hone their skills and thinking by giving them the right tools.
The unique and the best aspect of this program is that it works independent of any grading systems and hence the students will be encouraged to take intellectual risks. The program stresses on questioning and looking at the proofs of various mathematical concepts so as to understand the thought process behind its origin and encourage the students to develop a research attitude. The program also tries to knit together various topics of algebra and geometry, and encourage students to think about its applications in the real-life scenarios.
This document is a handbook for new employees at Valve, a video game company. It provides an overview of Valve's unique flat organizational structure, where employees choose their own projects and there is no traditional management. It discusses how employees should determine what projects to work on by finding areas where they can add the most value. It also covers peer reviews and performance evaluations at Valve. The overall goal is to help new employees understand Valve's non-hierarchical culture and feel empowered to contribute in a meaningful way.

The document summarizes the three fundamental principles according to Imaam Muhammad bin ‘Abdil-Wahhaab as:
1) Belief in the oneness of Allah - that He alone is worthy of worship and none besides Him.
2) Belief that Muhammad is the final prophet of Allah.
3) Belief that one must not take non-Muslims as allies or friends over fellow Muslims.
This document summarizes a presentation on fraud detection and concept drift adaptation with delayed supervised information. It discusses the challenges of concept drift, imbalanced classification from limited labeled data, and exploiting feedback from investigated transactions. The proposed solution uses a sliding window to adapt to concept drift, undersampling to balance delayed data, and separately handling feedback to give it more influence than delayed samples. Experiments on real and synthetic data show the benefit of the proposed approach over standard solutions. Future work includes adaptive classifier aggregation and implementation in big data architectures.

The document discusses six foundational principles of Islam:
1. The religion is best understood through the Quran and authentic Hadith.
2. Scholars must differentiate the religious message from its carriers or interpreters, and refer back to the primary sources when experts disagree.
3. Even Imam Abu Hanifa said that the Hadith takes precedence over his own opinions.
4. Islam as a religion is perfect, but individuals are fallible.
5. The Quran guides some and misguides others by design.
6. Differences arise when attaching to certain scholars rather than the Prophet and Companions.

Calibrating Probability with Undersampling for Unbalanced ClassificationAndrea Dal Pozzolo
This study examines how undersampling affects posterior probability estimates in unbalanced classification tasks. It shows that undersampling warps the posterior probabilities away from the true probabilities. However, the study presents a method to correct the warped probabilities using a simple formula, which provides calibrated probabilities without loss of predictive performance. Experiments on real-world datasets demonstrate that the corrected probabilities have better calibration than uncorrected probabilities while maintaining ranking quality.
When is undersampling effective in unbalanced classification tasks?Andrea Dal Pozzolo
This document analyzes when undersampling is effective for addressing class imbalance in classification tasks. It introduces the concepts of warping in posterior distributions and increased variance due to sample removal with undersampling. It presents a theoretical condition under which undersampling is expected to improve classification accuracy based on comparing the ranking error probability with and without undersampling. Experiments on synthetic univariate and bivariate datasets are used to illustrate factors influencing whether the condition holds.
'Lilavati' was one of the mathematical texts written by Bhaskaracharya-II (1114 - 1193 CE), a well-known Indian mathematician. In this presentation we have shared one of the techniques of multiplying numbers which has been explained in Lilavati.
