The use of electric heating concrete during construction in winter makes it possible to create an optimal thermal regime which the hardening process takes place, and obtain a structure required quality. When developing system for automatic control process, is necessary determine law regulating power heaters. This article presents method calculating structures formwork, essence reduce boundary v...

Combining the transformation project of certain strip steel rolling production line, the techniques process of walking beam heating furnace was elaborated in this paper. The practical application of LOS-T18-2ZC1 laser detector was elaborated. The network communication model of walking beam heating furnace control system was designed. The realization method of production process automation contr...

Background and Objectives: Red colored fruits such as cornelian cherry (Cornus mas L) are recognized as being healthy. The color of these fruits is an important sensory property in assessment of product quality therefore, minimizing the loss of color in the process is very important. Materials and Methods: In this study, comparison of the color, turbidity, degradation rate of anthocyanin, an...

In this paper, dynamic transient method and conventional degree-hours method (static) have been compared to estimate heating and cooling loads of building’s wall. All main wall surfaces of various orientations, i.e.South, West, East, North, and horizontal are considered in the climate of Tehran, Iran. In this study, a conventional wall structure, which is comprisedconcrete as main wall material...

Induction heating is a fast, efficient, precise and repeatable non-contact method for heating metals or other electrically-conductive materials. Induction heating is a process which is used to bond, harden or soften metals or other conductive materials. For many modern manufacturing processes, induction heating offers an attractive combination of speed, consistency and control. The induction he...

This paper describes a method for improving the speed of actuators based on shape memory alloys (SMA) by increasing the rate at which an SMA element can safely be heated. The method consists of measuring the electrical resistance of an SMA element, calculating a maximum safe heating current as a function of measured resistance, and ensuring that the actual heating current does not exceed this m...

the environmental scanning electron microscopy (esem) is a new development in the field of electron microscopy. in this study esem has been used to study the structure of veal semimembranosus muscle. four treatments, raw (control), conventional heating, domestic and industrial microwave heating, were observed using esem. the temperature used in conventional heating was 163 0c. frequency app...
