A parallelogram drive enables lightweight arms to have a higher rigidity and to reduce the actuator weight moved. Analysis of the flexible closed kinematic chain dynamics and design of the control are described in this paper. The system dynamics is derived by the Lagrangian formula via the assumed mode method. Holonomic constraints due to the geometry of the parallelogram mechanism must be impo...

A novel approach for VSI with an LCL output filter controller design for microgrids operating in grid-connected mode is presented in this paper. The controller structure is based on a multiloop control configuration in which the inner control loop is responsible for current regulation and the outer control loop generates the reference currents based on preset active and reactive power injection...

Image segmentation is one of the most common steps in digital image processing. The area many image segmentation algorithms (e.g., thresholding, edge detection, and region growing) employed for classifying a digital image into different segments. In this connection, finding a suitable algorithm for medical image segmentation is a challenging task due to mainly the noise, low contrast, and steep...

The CM-2 is an example of a connection machine. The strengths and problems of this implementation are considered. Then important issues in the architecture and programming environment of connection machines in general are considered. These are contrasted with the same issues in MD multiprocessors and multicomputers.

A method for connecting unfilled natural bamboo was proposed, comprising screws and metal plates. The is commonly used in timber connections, yet connections are rarely seen, mostly due to the perceived risk of splitting. This study aimed assess applicability through extensive testing short-term laterally loaded connection parallel fibre, including variation several parameters. An existing mode...

The present work provides a mathematically rigorous account on super fiber bundle theory, connection forms and their parallel transport, that ties together various approaches. We begin with detailed introduction to bundles. then introduce the concept of so-called relative supermanifolds as well bundles connections defined in these categories. Studying objects turns out be utmost importance orde...
