Dissertation zur Erlangung des akademischen Grades doctor rerum naturalium (Dr. rer. nat.) vorgelegt der Fakultät für Human- und Sozialwissenschaften der Technischen Universität Chemnitz vorgelegt von: Katja Schleinitz, geboren am 13.01.1983 in Zwickau eingereicht am: 29.01.2016 Tag der Disputation: 19.05.2016 Gutachter: Prof. Dr. Josef F. Krems, Technische Universität Chemnitz Prof. Dr. Mark Vollrath, Technische Universität Braunschweig ACKNOWLEDGEMENTS i ACKNOWLEDGEMENTS Over the past four years I have received support and encouragement by a great number of people. At the beginning, I want to thank my supervisor Prof. Krems for his support and that he gave me the opportunity to do my research in such an interesting field. He showed me, that research does not only take place in the academic “ivory tower”, but rather contributes to make our world a little bit safer. Moreover, I would like to thank Prof. Vollrath for his willingness to review my PhD thesis. Additionally, I would like to express my deep gratitude to Tibor Petzoldt. Without you, this work would never have been possible. Thanks for the countless hours of proofreading and discussions, your wise comments and suggestions as well as many cheerful hours, when you have given me some good laughs. -
32 Minis Newsletter Bicycles
Academy Art Museum academyartmuseum.org MINIS AT HOME volume 1, issue 32 Greetings kids, parents, grandparents, guardians, friends and neighbors! Welcome to issue 32 of Minis at Home newsletter. This is our last newsletter of the school year. We hope you have enjoyed reading the newsletters as much as we have enjoyed preparing them for you. Remember that exploring the natural world, working on projects together with your family, and making time to read are all important activities to keep mind and body healthy. This week’s theme = Bicycles It's that time of year when we are heading outside more and more as the weather becomes warmer and our days become longer. Some of us might enjoy a walk, some of us might ride horses, and some of us may play soccer, but many of us like to ride bikes and scooters best. Bicycle comes from “bi," which means two, and “cycle," which means circle. Wheels, of course, are shaped like circles. Bicycles have 2 wheels, 2 peddles, a frame and handlebars. There is a chain that is connected to cogs. When you push the pedals with your legs, this turns the chain, which then turns the back wheel. You steer the front wheel with the handlebars. The short name for “bicycle” is “bike.” It takes a little practice to balance on a bike. Children who are just learning to balance on a bike may use training wheels that keep the bike from falling over. Very young children can ride a tricycle (or “trike”), which has three wheels and can’t tip at all. -

This report looks at the history of e-bike development, the technical aspects of e-bikes, trends in sales and usage, ridership in Marin County, and specific actions public and private entities can do to support their use for transportation purposes. This includes, for example, subsidies to reduce the cost of e-bikes by employers in Marin County, and supporting facilities (such as secure bike parking) to improve the connection to transit. E-bikes may also be an effective extension of current transit and commuter rail (SMART) services in Marin County, although e-bike weight (50 to 70 pounds) make them too heavy to be loaded onto bus racks and they are not currently allowed on Golden Gate ferries. -

Grenoble Alpes, CNRS, GIPSA-lab, F-38000 Grenoble, France (e-mail: nadia.rosero, [email protected]). ∗∗ Univ. de la Sabana, Faculty of Medicine, Chia, Colombia (e-mail: [email protected]) Abstract: The paper presents a whole-body bio-energetic model of a cyclist which includes the mechanical dynamics of the bike. This model could be used to solve control-design problems for pedelec systems. The behavior of some physiological variables during cycling is reproduced by keeping an energy aware transfer flow. The modeling approach considers three main levels: i) physiological, ii) bio-mechanical and iii) pure-mechanical. -

Punta Gorda, April 1Th 2016 Florida Bicycle Association

I was concerned, with the moody weather at that day. Would somebody come in and get out for a test ride at all? When Christopher LeDew dropped in and it turned out later on, that he actually is a brother in the cause if it comes to electric bicycle. Some weeks later I got an e-mail from him with an article that is meanwhile published in the Messenger of the Florida Bicycle Association. I was so baffled to read in that article, that he really did mirror the information and facts he learned from me on electric bicycles, that I have to share this article with you. It may be a little bit more to read as usually, but it is certainly worth it. Thanks again Chris to give me the permission to publish this on my newsletter. And for the rest, enjoy the funny but still serious and accurate article on electric bicycle that follows here. Sincerely yours Phil Pfaeffli Team pedelecSQB FBA Newsletter Article Electric Bikes Those of you that know me, know that I have a soft spot in my heart for commuter cyclists. Anyone who chooses not to drive in the comfort of a Volvo station wagon and instead rides our busy urban streets in the height of rush hour; anyone who, behind a make-shift cubicle divider, takes a full body baby-wipes bath; anyone who then soldiers on through an eight-hour work day in wrinkled clothes and messed-up hair has earned my respect. -
Hardware Design Considerations for an Electric Bicycle Using BLDC Motor
www.ti.com Table of Contents Application Report Hardware Design Considerations for an Electric Bicycle Using a BLDC Motor Srivatsa Raghunath ABSTRACT A traditional bicycle is a two-wheel vehicle that is propelled by the rider who delivers muscle power through pedals that rotate one of the two wheels. The rider steers the front wheel to create a force that returns and maintains the vehicle center of gravity into a stable zone whenever necessary, thus keeping the bicycle upright. An electric bicycle carries batteries that deliver electric power to a motor that is coupled to either wheel. In most electric bicycles the rider can chose to use muscle power to deliver all, part, or none of the propulsion power required to maintain an adopted travel speed. Some models even sense pedal pressure and command the motor to deliver more power whenever the rider pedals harder.
