This paper presents a method that utilizes a memristor to replace the non-linear resistance of typical Chua’s circuit for constructing a chaotic system. The improved circuit is numerically simulated in the MATLAB condition, and its hardware implementation is designed using field programmable gate array (FPGA). Comparing the experimental results with the numerical simulation, the two are the very same, and be able to generate chaotic attractor.

Previous research has indicated that performing repetitions to failure at greater than 80% one repetition max (1 RM) one day per week using a non-­‐linear training program can maintain strength and power in many athletic populations. However, this finding has not been directly assessed in male university volleyball players. The purpose of this study was to determine if non-­‐linear training two days a week could maintain upper and lower body strength, and vertical jump power and height over the course of a competitive volleyball season, measured at three time points. Eleven trained Canadian Interuniversity Sport (CIS) male athletes were a part of a single training group which completed a maintenance program consisting of non-­‐linear training for 17 weeks. At each testing time point, the participants completed a bench press, squat, squat jump, countermovement jump, and three step jump and reach. We predicted that non-­‐linear resistance training of mixed intensities twice a week would allow players to maintain strength, vertical jump power, and vertical jump height. Results indicated that upper body strength can be maintained over the course of a competition period with non-­‐linear resistance training (p = 0.043). Scores for lower body strength, vertical jump squat jump power, vertical jump countermovement jump power, and vertical jump height increased over the course of the season (p's < 0.001, 0.14, 0.181, and 0.006, respectively). Our results indicate that male volleyball players can benefit from non-­‐linear training to maintain or improve performance when training at > 80% 1 RM to failure once a week during a competition season.

Definition Of

<p>In nonlinear static analysis of masonry buildings, the hysteric behaviour of masonry walls is commonly idealized through a bi-linear resistance envelope defined by the lateral stiffness of the wall, the ultimate shear resistance and the ultimate inter-storey drift. Therefore, it becomes fundamental to properly set the modulus of elasticity and shear modulus for masonry as well as to properly evaluate the drift capacity of the walls.</p><p>In the paper, the combined influence of shear modulus and drift capacity definition on the assessment of seismic performance of masonry buildings is investigated in details by means of a simplified non-linear pushover type algorithm developed by the authors. In particular, two different definitions are considered for the drift capacity, in terms of ductility and in terms of percentage of the inter-storey height, while for the shear modulus a reasonable set of values is investigated according a database collected combining masonry test results available in the relevant scientific literature with an in situ experimental campaign carried out by the authors.</p><p>The results show how the variation in shear modulus can lead to conflicting outcomes for the evaluation of seismic performance of masonry buildings depending on the assumed definition of drift capacity.</p>

A type of automatically interrupted triode oscillations is described which depends on the interaction between an oscillating triode circuit and. a circuit containing a non-linear resistance and a time-constant device. The theory of the circuit is developed and tested experimentally by means of oscillograms. The theory of the rise and decay of currents in a circuit containing an inductance and a non-linear resistance is dealt with in an appendix.
