Study on the End Winding Inductance of Three-Phase Windings in Two Layers
The paper deals with the problem of determining the stator end winding inductance of A.C. machines. It refers to the two-layer windings with shortened pitch, the relative pitch being less than one. The inductance has been determined by numerical analysis based on finite elements method (FEM), the procedure being described in this paper. In or...

Social networks in function of strengthening image and development of branch
There are a few things that we look at daily and in which marketing is not involved, and very often we are not even aware of the extent to which we are susceptible to various marketing messages that in some way affect us. Whether I want to admit it or not, we are all part of one big global marketing globally circulating ball and sends us vari...

A Dilemma Regarding a Model from Fluid Mechanics
In order to model natural phenomena, a faithful model describing the evolution of the analyzed phenomena must consider as many aspects as possible. An advantage of a correct representation of the studied phenomenon is the highlighting of the aspects hard to notice initially. To support these affirmations, two examples are brought into attenti...

Dual image steganography based on pixel shuffling
Steganography is a technique of hiding secret information into an innocent looking container. Although a large number of steganography techniques exist, there is a constant need for new ones because they have a relatively short lifespan, being constantly defeated by steganalysis methods. Least Significant Bit substitution (LSB) is one of the ...

Network control of Simatic S7-1200 PLCs for industrial processes
The paper presents different types of controlling and monitoring an industrial process through web interface, depending on the connection types made by PLC or HMI used in the process. We can control the industrial processes through HMI interface directly on the web or phone if we use a Weintek HMI in connection with a SIEMENS PLC for manipula...

An Accurate Technique for Finding the Coefficient of Rolling Friction Using the Inclined Plane Method
Finding the coefficient of rolling friction (CRF) by the inclined plane method is similar to the manner used in establishing the coefficient of sliding friction. For the rolling case, the difficulty arises from the fact that the usual devices employed in angular measurements present errors greater than the effective angle. The paper surmounts...
