Wi-Fi Positioning Technology Applied in the Cities
This paper deals with a problem of finding the right address in the new city or unknown part of the city, the right door. The psychological pressure on people in this situation can be quite large and unpleasant, especially when the GPS could not provide enough support. The outdoor position systems are based on GPS signal and besides that, they are ...

Vibration Monitoring of the Technical Condition of the Blade Unit of the Gas Pumping Unit Gpa-Ts-16S
Monitoring of the technical condition of gas pumping units (GPU), including the average power of the GPA- Ts-16S type, is important during operation, since damage to its main unit - the blade apparatus can lead to significant economic losses and, in some cases, to an accident. The analysis of the methods of parametric and vibroacoustic control rela...

Theoretical Investigation of the Tapered Thread Joint Surface Contact Pressure in the Dependence on the Profile and the Geometric Parameters of the Threading Turning
The tapered screw joints are widely used in the formation of the drill string. They consist of two parts - a box and a pin. during the process of screwing box and a pin the contact pressure between thread surfaces arises, the magnitude of which affects the intensity of wear on these surfaces. For the first time, the authors offer in this work to ch...

The Manure Influence on Cr2+, Cu2+, Mg2+ and Zn2+ Regime in the Green Waste Compost
The composting is one of the most effective recycling method of green waste. The presence of some heavy metals as Cr2+, Cu2+, Mg2+ and Zn2+ may influence the compost quality. Thus, by adding some components like manure the micronutrients and heavy metals regime suffer changes which might influence their bioavailability for plant uptake. The bioavai...

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...

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...
