To achieve the major objectives of the numerical simulation of the technological process of cold plastic deformation, are incorporated into the physical model three types of surfaces: cylindrical, conical and profiled. The ...

On the properties of exploitation of the parts, a major influence has the quality parameters of working surface. Under the term "quality superficial layer" it is understood the integrity of such indices as: geometric ...

This paper presents a method to control an operation process of a complex technical object, with the use of trivalent diagnostic information. Also, a general diagram of the complex technical object was presented, and its ...

Axial adjustment method for precessional transmissions includes the compensation error calculation and the determination compensator groups, achieved in the form of base and auxiliary rings. The compensator has on the base ...

In this paper we present a study of issues related for determination the real profile and the theoretical one of the precessional gear wheels.

The study is focused on measuring the oak chips/wine contact surface. Five samples were analysed with the doses used in oenology (2; 3; 4; 5 g.L−1). For example, for the dose of 2 g.L−1 there were obtained the surfaces, ...

Techniques for micro-oxygenation of wines are now accepted practices in wine manufacturing. But, at present time, only wine tasting and empirical know-how are used to control the oxygen input. Our work aims at a better ...

This paper addresses the issue of sizing cogeneration plants. A simple analytical expression has been obtained for cogeneration plants sizing and determining their share to cover the thermal load of either a consumption ...

In this paper, we extend to the design of electric power distribution networks the constructal method of deducing the multiple dimensions of the network from the maximization of global system performance. Unlike earlier ...

Sweet pepper is known not only for taste, aroma and flavor, but also for antioxidant effects and properties. Sweet pepper contains phenolic substances such as phenolic acids, flavonoids, phenolic diterpenes and volatile ...
