In this paper, a vacuum suction cup robot is introduced, which is used in drill bolt welding machine to add silver brazing sheets. This paper briefly discusses the application of vacuum power on the device. Then through the selection of the degree of vacuum and a vacuum generator, the selection and calculation of the chuck size specify the design process of the vacuum power system. Finally, through the working process of the manipulator and the structural design of the silver brazing box briefly introduce the movement of the vacuum suction manipulator.

This article deals with the problems of the need for the required volume and flow rate in the circuit with underpressure in the design of the gripping effector with active suction cups. It presents a process of designing a vacuum generator which is required to power such effector so that it guarantees a quick and secure fixation of handling objects (OM) at handling it with a robot. The article displays a means of determining of so-called evacuationtimes in the process of gripping of OM during the handling tasks.

Control Scheme

The main purpose of the paper is to control chaotic oscillation in a complex seven-dimensional power system model. Firstly, in view that there are many assumptions in the design process of existing adaptive controllers, an adaptive sliding mode control scheme is proposed for the controlled system based on equivalence principle by combining fixed-time control and adaptive control with sliding mode control. The prominent advantage of the proposed adaptive sliding mode control scheme lies in that its design process breaks through many existing assumption conditions. Then, chaotic oscillation behavior of a seven-dimensional power system is analyzed by using bifurcation and phase diagrams, and the proposed strategy is adopted to control chaotic oscillation in the power system. Finally, the effectiveness and robustness of the designed adaptive sliding mode chaos controllers are verified by simulation.

This paper reports on the primary school design processes carried out around the 1940s in the County of Hertfordshire in Great Britain, which later evolved into innovative strategies developed by Mary and David Medd in the Ministry of Education from the late 1950s. The whole process, undertaken during more than three decades, reveals a way of breaking with the traditional spatial conception of a school. The survey of the period covered has allowed an in-depth understanding of how learning spaces could be transformed by challenging the conventional school model of closed rooms, suggesting a new way of understanding learning spaces as a group of Centres rather than classrooms. Historians have thoroughly shown the ample scope of this process, which involved many professionals, fostering a true cross-disciplinary endeavour where the curriculum and the learning spaces were developed in close collaboration. A selection of schools built in the county has been used to typologically analyse how architectural changes began to arise and later flourished at the Ministry of Education. The Medds had indeed a significant role through the development of a design process known as the Built-in variety and the Planning Ingredients. A couple of examples will clarify some of these strategies, revealing how the design of educational space could successfully respond to an active way of learning.

Abstract The present work describes an integrated, two-phase computer-based method for fabricating marine propulsors using stereolithography. This new methodology seamlessly integrates stereolithography rapid prototyping techniques with the hydrodynamic design, structural design, and prototype testing of advanced marine propulsors in order to greatly increase the design process efficiency and reduce development time. Its use as applied to the design, fabrication, and testing of advanced propulsor prototypes for small weapon’s-scale undersea vehicles (e.g., Unmanned Underwater Vehicles (UUVs), lightweight and heavyweight torpedoes, etc.) is described in order to demonstrate specific strengths of the new method.
