Introduction to Tailoring by 3G Elearning English | January 1, 2023 | ISBN: 1984679031 | 230 pages | PDF | 50 Mb In the sixteenth and seventeenth centuries, tailors were responsible for making a variety of outer garments, including capes, cloaks, coats, doublets, and breeches. They gave shape to them by using coarse, stiff linen and canvas for interlining, horsehair cloth, and even cardboard stiffened with whalebone for structural elements. Imperfect or asymmetrical body shapes could be evened out with wool or cotton padding. Luxury garments were often lined with satins or furs to keep their wearers warm. Tailors were the structural engineers for women's fashions and made whalebone stays or corsets until the nineteenth century. A tailoring shop is a small establishment set up anywhere in a marketplace to provide services to individuals for making tailored garments as per their choice or fashion. From individual knowledge of understanding fabric quality and skill in cutting and stitching are important to run a tailoring shop successfully. Tailoring shops may undertake job work for made-ups and home textiles and interior decoration work. Tailoring is an important aspect of fashion design courses, which emphasize the style or cut of the garment and then sewn as per the fitting and body measurements. It can mean a whole new wardrobe for women who feel they never have the right fit.  Introduction to Solid State Physics English | 30 Dec. 2025 | ASIN: B0GDF3HRG3 | 240 pages | Epub | 230.19 KB Imagine opening a book that reads less like a textbook and more like a story-one that uncovers the secret lives of the materials you use every day. Why does copper let electricity race through it while rubber shuts it down? How can diamond be brutally hard, yet glass can flex, scratch, and then shatter without warning? And what's happening inside your phone screen when it suddenly glows with sharp, vivid color? This book is a guided tour of the solid world for curious minds-students, hobbyists, and anyone who wants to understand what matter is doing behind the scenes-without a single equation to slow you down. No math. No derivations. Just clear language, concrete examples, and an intuitive path from everyday observations to the powerful ideas that explain them. You'll start with the basics: what makes a solid a solid, and why some solids form beautifully ordered crystals while others freeze into disordered, glassy states. From there, you'll meet the forces that hold atoms together. Bonding isn't treated as dry theory, but as the quiet architect behind strength and softness, brittleness and ductility, transparency and color. Once you learn to "see" how structure and bonding work together, the behaviors of materials begin to feel logical rather than mysterious. Next, crystal structures come alive as repeating patterns with real consequences. Symmetry gives materials reliability; defects give them usefulness. You'll discover how tiny imperfections can harden metals, tune semiconductors, and decide whether a material survives years of stress or fails overnight. You'll also meet the restless lattice itself-always vibrating, always trading energy-explaining why some solids conduct heat well, why others trap it, and why temperature can make materials expand, warp, or crack. As the story deepens, electrons take center stage. You'll learn why metals shine, why conductivity can seem effortless, and how energy bands-explained in plain English-separate conductors, semiconductors, and insulators in a way that finally feels natural. From there, "doping" becomes a tale of precision: how adding tiny amounts of impurities turns a simple crystal into the beating heart of modern technology, enabling diodes, LEDs, lasers, and solar cells. Then you'll explore dielectrics and polarization-the physics behind materials that store electrical energy, respond to electric fields, and shape light, making capacitors, sensors, and displays possible. Magnetism follows as its own storyline: spinning electrons acting like microscopic compass needles, aligning and competing to create the magnetic behaviors we rely on in motors, data storage, and emerging spin-based electronics. And then comes the twist: superconductivity, where resistance vanishes and current flows without loss-powering MRI machines, particle accelerators, and the dream of ultra-efficient power systems. Finally, the book opens the door to modern frontiers: quantum wells, graphene, topological insulators, and qubits. Each wonder ties back to the same core theme-structure shapes behavior, and behavior shapes the technologies reshaping our lives. This isn't about memorizing facts. It's about building intuition, until ordinary objects start to look like the visible surface of a deeper, quantum story.  Introduction to Software for Chemical Engineers by Mariano Martiacuten English | March 24, 2025 | ISBN: 1040298818 | 888 pages | PDF | 55 Mb The field of chemical engineering and its link to computer science is in constant evolution, and engineers have an ever-growing variety of tools at their disposal to tackle everyday problems.

Introduction to Quantum Information Processing by Eduardo R. Mucciolo English | September 11, 2025 | ISBN: 1032775890 | 264 pages | MOBI | 7.96 Mb This book introduces quantum computing and quantum communications at the undergraduate level for students in the physical sciences, engineering, and mathematics, assuming no prior knowledge of quantum mechanics. It is a self-contained guide assuming only that the reader is familiar with physics at the college level, calculus (up to and including ordinary differential equations), and some matrix algebra and complex numbers. The book brings the reader up to speed with fundamental concepts in quantum information processing and builds a working knowledge of basic quantum algorithms, quantum error correction, and quantum communication protocols. It covers various models of quantum computation and some of the most common physical realizations of qubits. There is a good number of practice problems and exercises that rely on computer programming with the Qiskit language. The book can be used to prepare students of physics, mathematics, electrical and computer engineering, computer science, optics and photonics, and mathematics for internships and research experiences in quantum information processing, both during and after their undergraduate studies. It also helps those who plan to apply to graduate school and do research in this area.  Introduction to Political Analysis in R by H.

Letha Hughes Etzkorn, "Introduction to Middleware: Web Services, Object Components, and Cloud Computing" English | ISBN: 1498754074 | 2017 | 662 pages | EPUB | 19 MB "A stereotype of computer science textbooks is that they are dry, boring, and sometimes even intimidating. As a result, they turn students' interests off from the subject matter instead of enticing them into it. This textbook is the opposite of such a stereotype. The author presents the subject matter in a refreshing story-telling style and aims to bring the Internet-generation of students closer to her stories." |
