Advances in Engineering Research. Volume 31

Advances in Engineering Research. Volume 31 begins with an introduction to the main components of an introductory study of a problem and its related data collection and analysis requirements. This part is fundamental to help initiate the process of design research management, and focuses on the first phase of the pre-design study, in which the bases of design problem identification, interpretation, planning and solution exploration are established. Next, this compilation proposes the use of the Cat Swarm Optimization technique to indicate the ideal number of threads in local pools. This method was implemented and tested with a real-world integration process. The areas of Enterprise Application Integration and Discrete-event Simulation are explored, and the authors propose a new approach for identifying potential performance bottlenecks in the software design phase. Following this, the authors introduce a discrete-time motion camouflage control to make a robot approach a maneuvering pursuee while not rotating the Line-Of-Sight joining the pair. In practice, there is time delay between the time instant when the pursuee's position is measured and the time instant when the control is applied. Additionally, performances of the conventional linear and proposed nonlinear robust adaptive Kalman filters based integrated inertial, baro and GPS altimeters are tested via predetermined simulations. During simulations, in order to test these approaches, two kinds of measurement malfunction scenarios have been taken into consideration; continuous bias and measurement noise increment. Q-switched and mode-locked fiber lasers were demonstrated using tungsten disulfide 2D nanomaterials as a saturable absorber. The saturable absorber was fabricated by repeatedly dropping and drying WS2 solution onto a microfiber to form a nanosheet layer. Then the WS2 coated microfiber was placed in a ring laser cavity to generate Q-switched fiber laser operating at 1568 nm using a 2.4 m long Erbium-doped fiber as the gain medium. The authors go on to describe the present choice for inductive power transmission and to explain a new transmitter topology that can intrinsically minimize the problems associated with the present choice. A comparison between the present and proposed topologies is provided. In the closing investigation, kinetic studies of CaO+CO2 and CaO+SO2 reactions are performed by thermogravimetry. The kinetic parameters of these non-catalytic gas-solid reactions are determined using the sophisticated random-pore model.
