Book Description
See if this sounds familiar: you’ve just started a new diet, certain that it’s going to be different this time around and that it’s going to work. You’re cranking along, adjust to the new eating (and exercise) patterns and everything is going just fine. For a while.Then the problem hits. Maybe it’s something small, a slight deviation or dalliance. There’s a bag of cookies and you have one or you’re at the mini mart and just can’t resist a little something that’s not on your diet. Or maybe it’s something a little bit bigger, a party or special event comes up and you know you won’t be able to stick with your diet. Or, at the very extreme, maybe a vacation comes up, a few days out of town or even something longer, a week or two. What do you do?Now, if you’re in the majority, here’s what happens: You eat the cookie and figure that you’ve blown your diet and might as well eat the entire bag. Clearly you were weak willed and pathetic for having that cookie, the guilt sets in and you might as well just start eating and eating and eating.Or since the special event is going to blow your diet, you might as well eat as much as you can and give up, right? The diet is obviously blown by that single event so might as well chuck it all in the garbage. Vacations can be the ultimate horror, it’s not as if you’re going to go somewhere special for 3 days (or longer) and stay on your diet, right? Might as well throw it all out now and just eat like you want, gain back all the weight and then some.What if I told you that none of the above had to happen? What if I told you that expecting to be perfect on your diet was absolutely setting you up for failure, that being more flexible about your eating habits would make them work better? What if I told you that studies have shown that people who are flexible dieters (as opposed to rigid dieters) tend to weigh less, show better adherence to their diet in the long run and have less binge eating episodes?What if I told you that deliberately fitting in ‘free’ (or cheat or reward) meals into your diet every week would make it work better in the long run, that deliberately overeating for 5-24 hours can sometimes be a necessary part of a diet (especially for active individuals), that taking 1-2 weeks off of your diet to eat normally may actually make it easier to stick with in the long run in addition to making it work better.I can actually predict that your response is one of the following. Some may think I’m making the same set of empty promises that every other book out there makes. But I have the data and real-world experience to back up my claims. Or, maybe the idea of making your diet less strict and miserable is something you actively resist. I’ve run into this with many dieters; they seem to equate suffering and misery with success and would rather doom themselves to failure by following the same pattern that they’ve always followed rather than consider an alternate approach. Finally, maybe what little I wrote above makes intuitive sense to you and you want to find out more.Regardless of your reaction to what I’ve written, I already have your money so you might as well read on.I should probably warn you that this isn’t a typical diet book. You won’t find a lot of rah-rah or motivational types of writing, there are no food lists and no recipes. There are thousands of other books out there which fit that bill if that’s what you want but this isn’t it.

Book Description
This book presents the dynamic modeling and attitude control of flexible spacecraft with time-varying parameters. The dynamic characteristics, vibration control methods and attitude stabilization methods for spacecraft are systematically studied in respects of the theoretical modeling, numerical simulation and the ground experiment. Three active control theories in complex mode space are presented for flexible space structures. Optimal slew strategies based on variable amplitudes input shaping methods and coupling control methods are proposed for stabilization of flexible spacecraft. The research provides an important way to solve the problem of high-precision attitude control of flexible spacecraft with time-varying parameters. This book is appropriate for the researchers who focus on the multi-body dynamics, attitude and vibration control of flexible spacecraft.

Book Description
This book contains an edited versIOn of lectures presented at the NATO ADVANCED STUDY INSTITUTE on VIRTUAL NONLINEAR MUL TIBODY SYSTEMS which was held in Prague, Czech Republic, from 23 June to 3 July 2002. It was organized by the Department of Mechanics, Faculty of Mechanical Engineering, Czech Technical University in Prague, in cooperation with the Institute B of Mechanics, University of Stuttgart, Germany. The ADVANCED STUDY INSTITUTE addressed the state of the art in multibody dynamics placing special emphasis on nonlinear systems, virtual reality, and control design as required in mechatronics and its corresponding applications. Eighty-six participants from twenty-two countries representing academia, industry, government and research institutions attended the meeting. The high qualification of the participants contributed greatly to the success of the ADVANCED STUDY INSTITUTE in that it promoted the exchange of experience between leading scientists and young scholars, and encouraged discussions to generate new ideas and to define directions of research and future developments. The full program of the ADVANCED STUDY INSTITUTE included also contributed presentations made by participants where different topics were explored, among them: Such topics include: nonholonomic systems; flexible multibody systems; contact, impact and collision; numerical methods of differential-algebraical equations; simulation approaches; virtual modelling; mechatronic design; control; biomechanics; space structures and vehicle dynamics. These presentations have been reviewed and a selection will be published in this volume, and in special issues of the journals Multibody System Dynamics and Mechanics of Structures and Machines.

Book Description
Solve toddler challenges with eight key mindshifts that will help you parent with clarity, calmness, and self-control. In Why is My Child in Charge?, Claire Lerner shows how making critical mindshifts—seeing children’s behaviors through a new lens —empowers parents to solve their most vexing childrearing challenges. Using real life stories, Lerner unpacks the individualized process she guides parents through to settle common challenges, such as throwing tantrums in public, delaying bedtime for hours, refusing to participate in family mealtimes, and resisting potty training. Lerner then provides readers with a roadmap for how to recognize the root cause of their child’s behavior and how to create and implement an action plan tailored to the unique needs of each child and family. Why is My Child in Charge? is like having a child development specialist in your home. It shows how parents can develop proven, practical strategies that translate into adaptable, happy kids and calm, connected, in-control parents.

Book Description
This book starts with a short recapitulation on basic concepts, common to any types of robots (serial, tree structure, parallel, etc.), that are also necessary for computation of the dynamic models of parallel robots. Then, as dynamics requires the use of geometry and kinematics, the general equations of geometric and kinematic models of parallel robots are given. After, it is explained that parallel robot dynamic models can be obtained by decomposing the real robot into two virtual systems: a tree-structure robot (equivalent to the robot legs for which all joints would be actuated) plus a free body corresponding to the platform. Thus, the dynamics of rigid tree-structure robots is analyzed and algorithms to obtain their dynamic models in the most compact form are given. The dynamic model of the real rigid parallel robot is obtained by closing the loops through the use of the Lagrange multipliers. The problem of the dynamic model degeneracy near singularities is treated and optimal trajectory planning for crossing singularities is proposed. Lastly, the approach is extended to flexible parallel robots and the algorithms for computing their symbolic model in the most compact form are given. All theoretical developments are validated through experiments.

Book Description
A new approach is presented in this book for modelling multi-body systems, which constitutes a substantial enhancement of the Rigid Finite Element method. The new approach is based on homogeneous transformations and joint coordinates. Apart from its simple physical interpretation and easy computer implementation, the method is also valuable for educational purposes since it impressively illustrates the impact of mechanical features on the mathematical model.
