This book aims at providing basic technical information to the builders and architects which they normally seek from consultants. The content of this book is also expected to provide basic elevator knowledge to the students, particularly future Engineers, builders and architects. It is also my aim to help the employees of elevator companies, to get to know the elevators fully. Currently students do not get the opportunity to study about elevators. This book could lay the foundation for introducing " Basics of Elevator technology" as an elective subject. It is the author‟s belief that the civil, mechanical, Electrical or Electronic engineers & Architects who have done an elective in elevator engineering would find it easy to get absorbed in the Elevator industry. This book may also be a source of knowledge for the common man who manages housing societies. This book features Foreword from Mr Malhotra the former Managing Director of OTIS India and Mr Leandre Adifon the former Vice President of OTIS Worldwide Engineering, USA which justifies the value of this book.
This volume presents papers on the topics covered at the National Academy of Engineering's 2017 US Frontiers of Engineering Symposium. Every year the symposium brings together 100 outstanding young leaders in engineering to share their cutting-edge research and innovations in selected areas. The 2017 symposium was held September 25-27 at the United Technologies Research Center in East Hartford, Connecticut. The intent of this book is to convey the excitement of this unique meeting and to highlight innovative developments in engineering research and technical work.
Vertical transportation systems (elevators, lifts, escalators and passenger conveyors) are used in almost all buildings of more than a few stories high. Traffic design and control, namely the movement of people by natural and mechanical means, need to be planned carefully as the costs of under- or over-provision are considerable and changes are not always possible. The subject is covered in four sections. The basic principles of circulation and an introduction to lifts are set out at the beginning, and then traffic design methods are outlined, followed by an examination of analysis and control. The sections are complete in themselves and are presented in depth, with worked examples and case studies as appropriate. The latest analysis techniques are set out, and the book is up-to-date with current technology. The mathematics is simplified wherever possible and copious references are given for further study and examples. The practising vertical transportation engineer involved with the sizing of a vertical transportation installation will find this an excellent and authoritative resource. Other members of the design teams: architects, developers and owners, will find the book a useful reference, and the needs of researchers, lecturers and students of the subject will also be satisfied by this simple presentation of the underlying theory. The engineering aspects, which fall into the areas of manufacturing and production, are not covered, but the practical constraints and considerations are indicated.
Discover how to measure, control, model, and plan people flow within modern buildings with this one-stop resource from a leading professional People Flow in Buildings delivers a comprehensive and insightful description of people flow, analysis with software-based tools. The book offers readers an up-to-date overview of mathematical optimization methods used in control systems and transportation planning methods used to manage vertical and horizontal transportation. The text offers a starting point for selecting the optimal transportation equipment for new buildings and those being modernized. It provides insight into making passenger journeys pleasant and smooth, while providing readers with an examination of how modern trends in building usage, like increasingly tall buildings and COVID-19, effect people flow planning in buildings. People Flow in Buildings clearly defines the terms and symbols it includes and then moves on to deal with the measurement, control, modelling, and planning of people flow within buildings of all kinds. Each chapter contains an introduction describing its contents and the background of the subject. Included appendices describe measured passenger data and performed analyses. Readers will also benefit from the inclusion of: A thorough introduction to people-counting methods, including counting technology inside and outside buildings, passenger traffic components, and manual people-counting An examination of the passenger arrival process in building, including the Poisson arrival process and probability density function, and passenger arrivals in batches A consideration of daily vertical passenger traffic profiles, including two-way traffic profiles and the effects of inter-floor traffic An exploration of people flow solutions, including stairs, escalators, and elevators with collective and destination group control systems, as well as double-deck and multicar system People flow calculation and simulation models Elevator planning with ISO simulation method Elevator planning and evacuation of tall buildings Perfect for software designers in the private sector and academia, People Flow in Buildings will also earn a place in the libraries of elevator consultants, manufacturers, and architects who seek a one-stop reference for transportation devices from a functional and design perspective, as opposed to a hardware perspective.
As the digital economy changes the rules of the game for enterprises, the role of software and IT architects is also transforming. Rather than focus on technical decisions alone, architects and senior technologists need to combine organizational and technical knowledge to effect change in their company’s structure and processes. To accomplish that, they need to connect the IT engine room to the penthouse, where the business strategy is defined. In this guide, author Gregor Hohpe shares real-world advice and hard-learned lessons from actual IT transformations. His anecdotes help architects, senior developers, and other IT professionals prepare for a more complex but rewarding role in the enterprise. This book is ideal for: Software architects and senior developers looking to shape the company’s technology direction or assist in an organizational transformation Enterprise architects and senior technologists searching for practical advice on how to navigate technical and organizational topics CTOs and senior technical architects who are devising an IT strategy that impacts the way the organization works IT managers who want to learn what’s worked and what hasn’t in large-scale transformation
The authors take the reader through the history of the concept, technical design and economic practicalities of building an elevator to space, and, ultimately, the implications of what such a low cost transportation system would mean to society. Based on three years of NASA-funded studies and written for the technically literate layperson, Edwards and Westling discuss the recent technological advances that now make the space elevator feasible. They conclude by addressing the effects that the space elevator could have on mankind's future from communications and energy to colonizing space.
