The Design of Coffee provides a non-mathematical introduction to chemical engineering, as illustrated by the roasting and brewing of coffee. Hands-on coffee experiments demonstrate key engineering principles, including material balances, chemical kinetics, mass transfer, fluid mechanics, conservation of energy, and colloidal phenomena. The experiments lead to an engineering design competition where contestants strive to make the best tasting coffee using the least amount of energy - a classic engineering optimization problem, but one that is both fun and tasty! Anybody with access to a sink, electricity, and inexpensive coffee roasting and brewing equipment can do these experiments, either as part of a class or with your friends at home. The Design of Coffee will help you understand how to think like an engineer - and how to make excellent coffee! This revised second edition presents streamlined lab experiences, adds new bonus material on industrial coffee operations, and includes a new lab experience focused on sensory analysis during traditional cupping of coffee. FEATURES: * Covers all aspects of making coffee, from green beans to the final brew * Does not require calculus or college-level chemistry * Emphasizes the scientific method and introductory data analysis with guided data sheets and lab report questions * Includes 10 full experiments, each with background on key concepts, overview of necessary equipment, and detailed instructions: Lab 0 - Safety Overview and Introduction to Tasting Coffee Lab 1 - Reverse Engineering a Drip Coffee Brewer Lab 2 - Process Flow Diagram and Mass Balances for Coffee Lab 3 - The pH of Coffee and Chemical Reactions Lab 4 - Measuring the Energy Used to Make Coffee Lab 5 - Mass Transfer and Flux during Brewing Lab 6 - Coffee as a Colloidal Fluid and the Effect of Filtration Lab 7 - First Design Trials: Optimizing Strength & Extraction Lab 8 - Second Design Trials: Scaling Up to 1 Liter of Coffee Lab 9 - Design Competition and Blind Taste Panel

Manufacturers are becoming more aware of human factors in product design as a major competitive issue. In many product areas, manufacturers have reached a technology ceiling, which simply means that it is increasingly difficult to get ahead of the competition in terms of, for example, functionality, technical reliability or manufacturing costs. As a consequence, design has become a major battleground for manufacturers, and usability is recognized as being a central tenet of good design. This book provides a unique snapshot of current practice in human factors, identifying methods and techniques that work well under tight constraints and providing case study evidence of their effectiveness. The commercial implications of usability are discussed, and special attention is paid to two key trends: inclusive design and smart products. Inclusive design is about meeting the needs of all users with one design, which includes the elderly and the disabled. Smart products are multi-functional products with electronic interfaces containing a vast array of "helpful" functions. Industrial designers and manufacturing executives will find this text enlightening.

Usability ist eine der wichtigsten Herausforderungen bei der Webseitenerstellung – und wird häufig nur allzu leichtfertig vernachlässigt. Lernen Sie mit dieser überarbeiteten Neuauflage des Klassikers, wie Websites wirklich benutzt werden – mit aktualisierten Beispielen und einem neuen Kapitel über Mobile Usability. Steve Krug verdankt seine Erkenntnisse einer eigentlich nahe liegenden Methode: Er beobachtet, wie User mit einer Website umgehen und welche Hindernisse sich ihnen bei der Informationssuche in den Weg stellen. Anhand aussagekräftiger Beispiele, vieler Grafiken und einer Prise Humor erhalten Sie eine ganz neue Perspektive auf Ihr Websitekonzept. Krugs Usability-Prinzipien dienen als Leitfaden für die eigene Arbeit. Mit einfachen Tests kann jeder seine Website ohne viel Aufwand so optimieren, dass sie den Usability-Kriterien entspricht und sich intuitiv anwenden lässt. Wenn Sie diesen Klassiker schon einmal gelesen haben, werden Sie wieder entdecken, was DON’T MAKE ME THINK! so unverzichtbar für Webdesigner und -entwickler auf der ganzen Welt gemacht hat. Wenn Sie es noch nicht gelesen haben, werden Sie sehen, warum so viele Leute es als Pflichtlektüre empfehlen.

A comprehensive approach to the air vehicle design process using the principles of systems engineering Due to the high cost and the risks associated with development, complex aircraft systems have become a prime candidate for the adoption of systems engineering methodologies. This book presents the entire process of aircraft design based on a systems engineering approach from conceptual design phase, through to preliminary design phase and to detail design phase. Presenting in one volume the methodologies behind aircraft design, this book covers the components and the issues affected by design procedures. The basic topics that are essential to the process, such as aerodynamics, flight stability and control, aero-structure, and aircraft performance are reviewed in various chapters where required. Based on these fundamentals and design requirements, the author explains the design process in a holistic manner to emphasise the integration of the individual components into the overall design. Throughout the book the various design options are considered and weighed against each other, to give readers a practical understanding of the process overall. Readers with knowledge of the fundamental concepts of aerodynamics, propulsion, aero-structure, and flight dynamics will find this book ideal to progress towards the next stage in their understanding of the topic. Furthermore, the broad variety of design techniques covered ensures that readers have the freedom and flexibility to satisfy the design requirements when approaching real-world projects. Key features: • Provides full coverage of the design aspects of an air vehicle including: aeronautical concepts, design techniques and design flowcharts • Features end of chapter problems to reinforce the learning process as well as fully solved design examples at component level • Includes fundamental explanations for aeronautical engineering students and practicing engineers • Features a solutions manual to sample questions on the book’s companion website Companion website - www.wiley.com/go/sadraey

Designing is one of the foundations for change in our society. It is a fundamental precursor to manufacturing, fabrication and construction. Design research aims to develop an understanding of designing and to produce models of designing that can be used to aid designing. The papers in this volume are from the Sixth International Conference on Artificial Intelligence in Design (AID'00) held in June 2000, in Worcester, Massachusetts, USA. They represent the state of the art and the cutting edge of research and development in this field, and demonstrate both the depth and breadth of the artificial intelligence paradigm in design. They point the way for the development of advanced computer-based tools to aid designers, and describe advances in both theory and application. This volume will be of particular interest to researchers, developers, and users of advanced computer systems in design.
