This book is a quick guide that will help you through the basics steps to get you started selling products online. Using a drop shipping distributor you will be able to sell online without ever having to touch the merchandise. Your entire store can be running from your bedroom, black socks are optional. The customer orders a product from you, then you place the order with your distributor. The drop ship distributor will then ship the merchandise directly to your customer. If you have made online purchases there is a chance that you might have bought from a drop shipper. The book was written as a quick guide to give you the tools that you need to get started. After closing my Real Estate Company, I was searching for any easy, no stress business to start. I didn't want huge overhead, and having to work 80 hour weeks. I already had a full time job, and wanted to supplement my income without losing time from my family. Selling online had its appeal. I read several books on the topic. Some were very well written, and others filled my head on how I could be a millionaire. Although some of the books were great motivators, they didn't make me a millionaire. I wrote this book to help you start your first online store with realistic outlooks. Once the store is set up, it will not demand much of your time, or take you away from your family. Since the startup cost is low, you can take the skills that you learned from opening your first online store, and open up several more. Opening an online reseller store will not make you instantly rich, but it will be a nice supplement to your income.
This book is devoted to new methods of control for complex dynamical systems and deals with nonlinear control systems having several degrees of freedom, subjected to unknown disturbances, and containing uncertain parameters. Various constraints are imposed on control inputs and state variables or their combinations. The book contains an introduction to the theory of optimal control and the theory of stability of motion, and also a description of some known methods based on these theories. Major attention is given to new methods of control developed by the authors over the last 15 years. Mechanical and electromechanical systems described by nonlinear Lagrange's equations are considered. General methods are proposed for an effective construction of the required control, often in an explicit form. The book contains various techniques including the decomposition of nonlinear control systems with many degrees of freedom, piecewise linear feedback control based on Lyapunov's functions, methods which elaborate and extend the approaches of the conventional control theory, optimal control, differential games, and the theory of stability. The distinctive feature of the methods developed in the book is that the c- trols obtained satisfy the imposed constraints and steer the dynamical system to a prescribed terminal state in ?nite time. Explicit upper estimates for the time of the process are given. In all cases, the control algorithms and the estimates obtained are strictly proven.
Introduction Science does not have to be a scary thing reserved for people who wear white lab coats and work in sterile looking laboratories. Many scientists do not work in a lab. Some wear their favorite jeans, sneakers, and a T-shirt every day. Science does not have to be complicated by math. The basic concepts of science are as important as the math that is usually used to describe what is happening. Science does not have to involve experiments that damage the Earth or aid in making bigger, more powerful guns and bombs. Environmental scientists perform experiments that help the environment. Medical researchers do work that relieves pain and prolongs life. Science can be fun. If it weren't for science, we wouldn't have TVs, arcade games, ovens, TV dinners, microwaveable popcorn, bicycles, VCRs, elevators, escalators, cars, motorcycles, sewing machines, paper, or computers. Science is something that you can do every day of your life-using objects that you find in your house, in your yard, or at a store. When I was a youngster, I always wanted to know what made things work. I liked to do experiments. There were not many books that explained scientific principles using normal, everyday objects. Later on, as an adult, I wanted to write a few books that would help students perform experiments and have fun, while learning science at home. Sometimes it's a real drag to sit and listen to a teacher explain things. It can be much more fun-and more revealing-to perform these experiments and observations yourself. This book is intended to help you learn about science by performing experiments and making observations with items that you can find in almost any housewares store or housewares department of a large department store. You do not have to buy any of the items described in this book-you can examine them to see how they work while browsing in the store. But if you decide to do this, be sure to handle the merchandise carefully. Do not break or destroy the items or their packaging. To write this book, I went to a number of housewares stores and found many items that utilize scientific principles. Some of these items are so simple that you might not realize that there is a scientific basis to them. After you read this book, you might want to take some friends through one of these stores and ask them if they know why certain things work. Scattered throughout this book you will see a safety symbol. Ask an adult to help you whenever you see this symbol. The symbol indicates that the experiment is a little bit dangerous or difficult. I'd hate to see you get discouraged or hurt while you're learning about science in a housewares store!
