Computer Aided Analysis Of Kinematics And Kinetostatics Of Six-Bar Linkage Mechanism Through The Contour Method, Qelaj Mehmet, Likaj Ramë
Computer Aided Analysis Of Kinematics And Kinetostatics Of Six-Bar Linkage Mechanism Through The Contour Method, Qelaj Mehmet, Likaj Ramë
UBT International Conference
In this paper is presented a six-bar linkage mechanism of the pump for oil extrusion. In this mechanism are introduced even higher kinematic pairs. Dimensions and other incoming links will be adopted as necessary. For the six-bar linkage mechanism will be carried out the kinematic analysis and for all linkages will be presented the displacement, velocity and acceleration. The analysis will be performed by MathCad software, while kinetostatic analysis will be carried out using Contour Method, comparing results of two different software‘s MathCAD and Working Model. The simulation parameters will be computed for all points of the contours of mechanism.

Measures of complexity and entropy have not converged to a single quantitative description of levels of organization of complex systems. The need for such a measure is increasingly necessary in all disciplines studying complex systems. To address this problem, starting from the most fundamental principle in Physics, here a new measure for quantity of organization and rate of self-organization in complex systems based on the principle of least (stationary) action is applied to a model system - the central processing unit (CPU) of computers. The quantity of organization for several generations of CPUs shows a double exponential rate of change …
A Quantitative Measure, Mechanism And Attractor For Self-Organization In Networked Complex Systems, Georgi Georgiev
A Quantitative Measure, Mechanism And Attractor For Self-Organization In Networked Complex Systems, Georgi Georgiev
Biological and Physical Sciences Department Faculty Works
Quantity of organization in complex networks here is measured as the inverse of the average sum of physical actions of all elements per unit motion multiplied by the Planck’s constant. The meaning of quantity of organization is the number of quanta of action per one unit motion of an element. This definition can be applied to the organization of any complex system. Systems self-organize to decrease the average action per element per unit motion. This lowest action state is the attractor for the continuous self-organization and evolution of a dynamical complex system. Constraints increase this average action and constraint minimization …
Which Accelerates Faster A Falling Ball Or A Porsche?, James D. Rall, Wathiq Abdul-Razzaq
Which Accelerates Faster A Falling Ball Or A Porsche?, James D. Rall, Wathiq Abdul-Razzaq
Faculty & Staff Scholarship
An introductory physics experiment has been developed to address the issues seen in conventional physics lab classes including assumption verification, technological dependencies, and real world motivation for the experiment. The experiment has little technology dependence and compares the acceleration due to gravity by using position versus time graphs and the kinematic equation. The students are then asked to compare the acceleration they found to the one of a Porsche car which they seem surprised when they learn about it. This experiment may contribute significantly to the understanding of the concept of acceleration and the appreciation for the force of gravity.

Where Is The Best Place To Sit On A Roller Coaster? Forces, Physics, And Fun At Disneyland, Kelsey Lubetich
Where Is The Best Place To Sit On A Roller Coaster? Forces, Physics, And Fun At Disneyland, Kelsey Lubetich
Scripps Senior Theses
The work presented in this thesis was undertaken to quantitatively determine the best place to sit on a roller coaster. Maximizing the time spent feeling weightless and the highest value of negative Z acceleration were used as criteria for the best seat. Acceleration values were measured on the California Screamin' roller coaster at Disney California Adventure Park using an iPhone and an application to record data from its accelerometers. After analyzing acceleration data, it was determined that the front row had the greatest negative acceleration in the z direction and was therefore the "best place" to sit.

Multi-spoke cavities are well-known options for acceleration of heavy and light ions. A recently developed multi-spoke cavity for β=1 presents an attractive opportunity to use this cavity type for electron accelerators. One of the main attractive features of this cavity type is its compactness for relatively low frequency. A simplified design at 500 MHz allowed building of a multi-spoke cavity and cryomodule in a 2-year time frame with confidence and development of effective manufacturing techniques. It also constitutes an important step in proving the usefulness of this kind of cavity design for new applications in the electron machines. Niowave is …
