  • THE BENEFITS of LEARNING to JUGGLE for CHILDREN Written by Dave Finnigan
    THE BENEFITS OF LEARNING TO JUGGLE FOR CHILDREN Written by Dave Finnigan Fitness, Motor Skills, Rhythm, Balance, Coordination Benefits . Students can start acquiring pre-juggling skills in pre-school and kindergarten by learning to toss and catch one big, colorful, slow-moving nylon scarf. Once tossing and catching becomes routine, you can use one nylon scarf anywhere that you would normally use a ball or beanbag for most games and many individual challenges. Just think of the scarf as a "ball with training wheels." Scarf juggling and scarf play progresses in a step-by-step manner from one, to two, and on to three. Scarf play and scarf juggling requires big, flowing movements. Children get a great cardio-vascular and pulmonary work-out when they juggle scarves, exercising the big muscles close to the head and close to the heart. They will find scarf juggling to be a great deal of work and lots of fun at the same time. Once they move on to beanbags or other faster moving equipment, they get exercise not only from tossing, but from bending over to pick up errant objects as well. Once a student can juggle continuously, they can "workout" with heavy or bulky objects such as heavyweight beanbags, basketballs, or other items which provide strenuous exercise while they improve focus and dexterity. Because all of this tossing and catching activity can be done to music, you can use different types of music to help children acquire a sense of rhythm and a natural "beat." By working together, students can participate in a group activity requiring concentration and attention to task and reinforcing rhythm.

    UNIVERZA V LJUBLJANI FAKULTETA ZA ŠPORT Športna vzgoja Vpliv gibalnih sposobnosti na žongliranje Diplomsko delo MENTOR: prof. dr. Ivan Čuk SOMENTORICA: doc. dr. Maja Bučar Pajek RECEZENTKA: prof. dr. Maja Pori AVTOR: Blaž Slanič Ljubljana, 2015 ZAHVALA Zahvaljujem se vsem žonglerjem, brez njih diplomskega dela ne bi mogel izpeljati. Zahvala gre tudi mentorju, profesorju dr. Ivanu Čuku, ki mi je pomagal pri sami izvedbi diplomskega dela. Hvala partnerki in staršem, ki me pri mojih žonglersko-akrobatskih podvigih podpirate in mi stojite ob strani. HVALA. Ključne besede: žongliranje, gibalne sposobnosti, učinkovitost Vpliv gibalnih sposobnosti na žongliranje IZVLEČEK: Ker je žongliranje v Sloveniji zelo malo poznano, smo naredili raziskavo o vplivu gibalnih sposobnosti na unčikovitost v žongliranju. V raziskavi smo testirali gibalne sposobnosti slovenskih žonglerjev vseh starosti. Raziskava je vsebovala teste hitrosti, moči, ravnotežja, preciznosti, reakcijskega časa in ritma. Vse teste smo izvedli z levo in desno roko. Pogoj za sodelovanje na raziskavi je bil, da posameznik zna žonglirati s petimi žonglerskimi žogicami. Sodelovalo nas je 16 žonglerjev, starih med 13 in 40 let, in sicer 15 moških in 1 ženska. Na podlagi rezultatov smo ugotavljali, katere od gibalnih sposobnosti so tiste ključne, ki pripomorejo k lažjemu in bolj kontroliranemu žonglerskemu udejstvovanju. Podatki so bili obdelani v programu Excel 2010 in SPSS 16.0. Iz naših rezultatov je razvidno, da imata na učinkovitost v žongliranju največji vpliv bobnanje leva roka (ritem in tempo leve roke) in starost posameznika. Keywords: Juggling, motor skills, efficiency Effects of motor skills on juggling Because of the lesser known nature of jugging in Slovenia, we made our research on the effects of motor skills on it.

To assist in the detection of spurious and the correction of inaccu- rate pedigrees, is one of the purposes of the present publication, in which respect the first Volume has been of acknowledged utility. The two together, it is hoped, will form a comprehensive and tole- rably correct Register of Pedigrees. It will be observed that some of the Mares which appeared in the last Supplement (whereof this is a republication and continua- tion) stand as they did there, i. e. without any additions to their produce since 1813 or 1814. — It has been ascertained that several of them were about that time sold by public auction, and as all attempts to trace them have failed, the probability is that they have either been converted to some other use, or been sent abroad. If any proof were wanting of the superiority of the English breed of horses over that of every other country, it might be found in the avidity with which they are sought by Foreigners. The exportation of them to Russia, France, Germany, etc. for the last five years has been so considerable, as to render it an object of some importance in a commercial point of view.

  • © 2020 Alexandra Q. Nilles DESIGNING BOUNDARY INTERACTIONS for SIMPLE MOBILE ROBOTS
    © 2020 Alexandra Q. Nilles DESIGNING BOUNDARY INTERACTIONS FOR SIMPLE MOBILE ROBOTS BY ALEXANDRA Q. NILLES DISSERTATION Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Computer Science in the Graduate College of the University of Illinois at Urbana-Champaign, 2020 Urbana, Illinois Doctoral Committee: Professor Steven M. LaValle, Chair Professor Nancy M. Amato Professor Sayan Mitra Professor Todd D. Murphey, Northwestern University Abstract Mobile robots are becoming increasingly common for applications such as logistics and delivery. While most research for mobile robots focuses on generating collision-free paths, however, an environment may be so crowded with obstacles that allowing contact with environment boundaries makes our robot more efficient or our plans more robust. The robot may be so small or in a remote environment such that traditional sensing and communication is impossible, and contact with boundaries can help reduce uncertainty in the robot's state while navigating. These novel scenarios call for novel system designs, and novel system design tools. To address this gap, this thesis presents a general approach to modelling and planning over interactions between a robot and boundaries of its environment, and presents prototypes or simulations of such systems for solving high-level tasks such as object manipulation. One major contribution of this thesis is the derivation of necessary and sufficient conditions of stable, periodic trajectories for \bouncing robots," a particular model of point robots that move in straight lines between boundary interactions. Another major contribution is the description and implementation of an exact geometric planner for bouncing robots. We demonstrate the planner on traditional trajectory generation from start to goal states, as well as how to specify and generate stable periodic trajectories.

  • Jaime Bobadilla Molina.Pdf
    c 2013 Jaime Leonardo Bobadilla Molina MINIMALIST MULTI-AGENT FILTERING AND GUIDANCE BY JAIME LEONARDO BOBADILLA MOLINA DISSERTATION Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Computer Science in the Graduate College of the University of Illinois at Urbana-Champaign, 2013 Urbana, Illinois Doctoral Committee: Associate Professor Samuel T. King, Chair Professor Steven M. LaValle, Director of Research Professor Tarek Abdelzaher Assistant Professor Dylan A. Shell, Texas A&M University ABSTRACT Advances in technology have allowed robots to be equipped with powerful sensors, complex actuators, computers with high processing capabilities, and high bandwidth communication links. This trend has enabled the development of sophisticated algorithms and systems to solve tasks such as navigation, patrolling, coverage, tracking, and counting. However, these systems have to deal with issues such as dynamical system identification, sensor calibration, and computation of powerful filters for state-feedback policies. This thesis presents novel techniques for tackling the above mentioned tasks. Our methods differ from traditional approaches since they do not require system identification, geometric map building, or state estimation. Instead, we follow a minimalist approach that takes advantage of the wild motions of bodies in their environment. The bodies move within regions connected by gates that enforce specific flows or provide simple sensor feedback. More specifically, five types of gates are proposed: 1) static gates, in which the flow direction of bodies cannot be changed during execution; 2) pliant gates, whose flow directions can be changed by gate-body collisions; 3) controllable gates, whose flow directions can be changed by powered actuators and sensor feedback; 4) virtual gates, in which the flow is affected by robot sensing and do not represent a physical obstruction; and 5) directional detection gates that do not change the flow of bodies, but simply detect bodies’ transitions from region to region.
