Amish-English sleuthing duo Deborah Yoder and Callie Harper set out to solve a murder. But more than an innocent man’s future is at stake. In book two of the Shipshewana Amish Mystery series, God’s grace touches the long-lost past as well as lives shaken by current tragedy. There's more to the quaint northern Indiana town of Shipshewana than handcrafted quilts, Amish-made furniture, immaculate farms and close-knit families. When a dead girl is found floating in a local pond, murder is also afoot. And Reuben, brother of Deborah's best friend's fiancé, is in jail as the suspect! Reuben refuses to divulge any information, even to clear himself of a crime Deborah is certain he didn't commit. So, with her English friend Callie—fellow sleuth and owner of Daisy's Quilt Shop—Deborah sets out to uncover the truth. But the mystery deepens when an elderly man seeks Callie's help in finding his long-lost daughter, missing since the days of the 1965 Palm Sunday Tornadoes. An old man who has lost his past. A young man who may lose his future. Once again Deborah and Callie find themselves trying to piece together a crazy quilt of lives and events—one that can bring unexpected touches of God's grace and resolve the tragedy that has shaken this quiet Amish community.
This textbook provides an introduction to the mathematics on which modern cryptology is based. It covers not only public key cryptography, the glamorous component of modern cryptology, but also pays considerable attention to secret key cryptography, its workhorse in practice. Modern cryptology has been described as the science of the integrity of information, covering all aspects like confidentiality, authenticity and non-repudiation and also including the protocols required for achieving these aims. In both theory and practice it requires notions and constructions from three major disciplines: computer science, electronic engineering and mathematics. Within mathematics, group theory, the theory of finite fields, and elementary number theory as well as some topics not normally covered in courses in algebra, such as the theory of Boolean functions and Shannon theory, are involved. Although essentially self-contained, a degree of mathematical maturity on the part of the reader is assumed, corresponding to his or her background in computer science or engineering. Algebra for Cryptologists is a textbook for an introductory course in cryptography or an upper undergraduate course in algebra, or for self-study in preparation for postgraduate study in cryptology.
This introductory textbook takes a problem-solving approach to number theory, situating each concept within the framework of an example or a problem for solving. Starting with the essentials, the text covers divisibility, unique factorization, modular arithmetic and the Chinese Remainder Theorem, Diophantine equations, binomial coefficients, Fermat and Mersenne primes and other special numbers, and special sequences. Included are sections on mathematical induction and the pigeonhole principle, as well as a discussion of other number systems. By emphasizing examples and applications the authors motivate and engage readers.
Understanding Mathematics is a carefully written series of mathematics to help students encourage the study of mathematics in the best interactive form. It contains ample practice material, attractive illustrations and real-life examples for the students to relate the topics with their everyday life. Special care has been taken while teaching topics like geometry and probability to the students. Keeping in mind the development status and comprehension level of students, the text has been presented in a well graded manner.
Targeting Mathematics series consists of nine textbooks; one for Primer and eight textbooks for classes 1–8. These books have been formulated strictly in accordance with the Continuous and Comprehensive Evaluation (CCE) approach of Central Board of Secondary Education (CBSE) and are based on the latest syllabus. The series also conforms to the guidelines of National Curriculum Framework 2005. The books have been written by experienced and renowned authors.
The revised edition of the series Foundation Mathematics for Classes 6, 7 and 8 is based on the latest curriculum prepared and recommended by the Council for the Indian School Certificate Examinations, New Delhi. The present mathematics curriculum aims to develop a number ofMathematical Skills (like Numerical Calculation, Algebraic Manipulation, Spatial Visualisation, Data Analysis, Measurement, Estimation and Approximation) and Mathematical Processes (like Reasoning, Communication and Connections, Problem solving and Heuristics, Estimation, Technology etc.) among students at these levels. This series has been developed and designed keeping in mind the following objectives of the latest curriculum : Students should : • Enjoy learning of mathematics. • Learn important mathematics that is much more than few formulas and mechanical procedures of solving problems. • Pose and solve meaningful problems. • See mathematics as something to talk about, to communicate, to discuss among themselves, to work together on. • Understand the basic structure of mathematics : Arithmetic, algebra, geometry and trigonometry, the basic content areas of school mathematics, all offer a methodology of abstraction, structuration and generalization Goyal Brothers Prakashan
