One of the most important problem to solve in the robots Kinematics and Dynamics is analyze of the joint’s angular and linear accelerations. Because the movements of the robot’s bodies going in the 3D space, the mathematical algorithm must be written in the complex matrix form. The paper show how some cases of the trapezoidal relatives’ velocities characteristics in a joints determine the variation of the acceleration’s vectors in the 3D space. The maximal values of these variations of the angular and linear accelerations influence the variation of the moments and forces. The analyze was made by using the Neutrosophic theory and vitual LabVIEW instrumentation. In a literature are described some methods of the assisted analyze of the acceleration without show the used mathematical model, without one critical analyze of the cases that must be avoid and finally without some conclusions for the researchers. The paper shown all LabVIEW virtual instruments (VI) used for this assisted research. By solving the assisted research of the acceleration will be open the way to the assisted research of the robots’ dynamic behavior, to choose the optimal constructive and functional parameters (dimensions of the bodies, simultaneously, successive or complex configurations of the movements in the robot’s joints, optimal values of the constant relative joint’s velocities, etc.) of the robots to obtain the minimum variation of the forces and moments. The method that was shown in the paper solves one small part of the complex problems of the robot’s kinematics and dynamics.

Escape Room is an adventure game usually used for team building but can also be used to enhance group learning experiences, as teams need to solve problems to escape a locked room. Immersive technology such as Mixed Reality (MR) makes it possible to enhance users’ experience of physical escape rooms with rich digital context. However, most MR designs require special equipment or applications to be installed and it is problematic to make the system scalable. While, most commercial products are used for entertainment purposes; in this paper, a scalable interactive MR escape room simulation for anatomy learning is introduced. This paper outlines the background, design concepts, implementation and test result. It demonstrates how to make good use of MR technology in a standard classroom setting, whilst combining the learning resources with an escape room game to provide a better learning experience in human anatomy.

The presented paper descries the implementation of a discrete control law, for an industrial manipulator, using MATLAB as computer software. The software implementation is done in order to test the overall performances of the discrete control law, since the on-site testing is not possible due tot the continuous functioning of the industrial manipulator as an unloading billets machine from a rotary hearth furnace, part of the hot rolling process. First, the magnitude optimum criterion, the Kessler variant, is applied as tuning method for the industrial manipulator’s positioning system since the continuous model is already known, due to prior research. Further, the discrete control is derived from the pulse transfer function yielded from digitizing the continuous control. The discrete control law is implemented as a discrete control structure using unit delay blocks and as a dependency law using the MATLAB function block. The overall performances are tested, and they meet the performance expected by Kessler's tuning method.

Electronic trading amounts for the vast majority of all financial transactions with bonds and equities in the world. This type of trading is based largely on the brokering of messages from the buy side, brokers or financial institutions, to a sell side (usually an exchange). Since not all trading is done at the same time these messaging systems need to account for server down times, sequencing, high throughput and performance requirements. Therefore, most fintech companies employ queuing mechanism to manage the message flow. This paper analyzes the way in which Kafka, one of the premiere messaging systems currently in use, can simplify various systems in use such as message brokering, persistence or fault tolerance. The authors of this paper hope to demonstrate the use of Kafka as a messaging system, backup solution and alert broker for software operators and developers with low fault-tolerance and rigid up-time requirements.

The purposes of this study are to formulate a mathematical model of tumor based on age structure and to simulate the model. We propose four classes: tumor cell, CTL cell, helper T-cell, and chemotherapy drug. For the initial research, we focused for tumor cell class which formed as age structure. Simulation of the model can be interpreted as behavior of solutions.

In this paper, an incompressible, two-dimensional (2D), time-dependent, and laminar Newtonian fluid flow in a square cavity is simulated in order to investigate vortex dynamics in cavities. Navier-Stokes equations in vorticity-stream function formulation are solved numerically using the finite difference method (FDM) and alternating direction implicit (ADI) technique as they are computationally effective. Two original, distinguished, and unexplored cases of the three-sided lid-driven cavity have been investigated. In case (1) the upper and lower walls are translated to the right whereas the left wall is translated upward and the right wall remains stationary. Furthermore, in case (2) the upper wall is translated to the right but the lower wall is translated to the left whereas the left wall is translated downward and the right wall remains stationary. Moreover, the speed magnitude is unity for all moving walls. However, a MATLAB code is developed, used, and validated by studying the one-sided lid-driven cavity. The results were in a very good agreement. Besides, stream function and vorticity values in addition to the location of primary and secondary vortices’ centers inside the square cavity have been revealed at low and intermediate Reynolds numbers, typically (Re=100 to 2000). Moreover, as Reynolds number increases, more secondary vortices are generated near the cavity corners and the main primary vortex approaches the cavity center.
