Adaptive Fuzzy-FMEA Expert System for Predictive Control Industrial Processes with Example
Modern processing is a combination of individual production cell, designed to complete the business of manufacturing parts of subassemblies and their integration into the final product of the product. The success of such a system depends on stability operations while minimizing the possible errors in the system. The continuous monitoring system is ...

Applications of the Thermoelectric Energy Harvester in Air Conditioning Condenser Unit
The devices that convert heat into usable electricity and use the three established thermoelectric effects known as the Peltier, Seebeck and Thomson effects are thermoelectric generators (TEG). These devices can generate power how long as there is a heat source. TEGs are made from thermoelectric modules and the cost of this modules is high, but the...

Concept for a Precise Academic Gripper
A new, precise, scalable multi-purpose gripper system for academic research purposes is proposed. The multi-purpose gripper is intended to be easily adapted to different tasks and object sizes. The gripper system is driven by two separate motor-gear-lead spindle units, operated by a small CNC control. Software running on the CNC unit is completely ...

Influence of Digital Transformation on the Customer Relationship
The importance of digital technologies is continuously increasing for the customers and thereby also for the companies. Examples for the digital transformation are the usage of smartphones and other gadgets as well as social media channels as Twitter and Facebook. The changing behavior of the customers has also impact of the relationship between a ...

Multicriteria Modeling with the AHP and FAHP Methods
In order to solve complex decision-making problems, MCDM has recently known a fast development. One of the main differences between the decision models consists in the way of evaluating the numeric and the non-numeric data that interfere while solving a problem. If the number of the criteria is not high and the evaluation contains both quantitative...

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 manipulating T...

Reactive Power Consumption Analysis of a Medium Sized Factory
The paper achieves a study on the reactive power consumption in case of a medium sized factory. The factories as others industrial consumers usually have the power factor lower than the neutral one, which in Romania is 0.92; that is why these types of consumers have to pay for reactive power. The reason for the power factor is small (sometimes much...

Research on the Integration of Systemic Thinking Applied Technical Field
Technical needs a permanent revision of thinking and orientation of a restructuring of how to integrate its components to keep up with the demands of the information society. Systems thinking provides for technical field models that make it more dynamic and oriented for interconnection, information and interchange. Our approaches will bring togethe...

S-Parameters Utilization for Analysis of High Frequency Analogue Two- Port Circuits
This study, using the theory of electric circuits, shows the right definition of scattering parameters (S- parameters) for any two-port electric circuit and the practical way to use these parameters in streamline the processes of information transmission and propagation, and the transfer of the active power from the electric quadrupole input (outpu...

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...
