The differential equations for torsional-distortional analysis of a double spine mono-symmetric box girder section were obtained following Vlasov's theory. The evaluation of Vlasov's coefficient of the governing differential equations formed a major part of this work. This involved the valuation of the various strain mode diagrams for the box section and an assessment of the strain mode interaction to ascertain the relevant strain modes that affect torsional and distortional displacements. Vlasov's coefficients for the governing equations of equilibrium were obtained using Morh's integral for displacement computations diagram multiplication of the strain modes diagram. By substituting the coefficients into the governing equilibrium equation, a set of coupled fourth order differential equations.

Development and technological advancement have made it possible to automate tasks or robotize them in order to save costs and time in labor. That is why more and more industries choose to automate their processes and do so through a PLC programmable logic controller, due to its practicality, ease of use and programming. For this reason, this work presents the design of a control applied to a pumping system through a PLC and with the use of an HMI interface..

Information System Securityis critical to all modern computer users (individuals and organizations). To insure that information remain secure, many organizations implemented various security structure to protect IS security from malicious incidents by establishing security procedures, processes, policies and information system security organization structures. However, despite of all the measures, information security is still a catastrophe. Poor understanding of information security key factor seem to be the main problem. The difference in ICT infrastructure and implementations as well as usage results into...........

High-strength steels have suitable mechanical properties to meet all the requirements of the end consumer while at the same time being economically suitable for the manufacturer and meeting strict environmental standards. The main use of these materials is in the automotive industry, where reducing the weight of cars and increasing passenger safety is required. This article deals with the evaluation of the limit drawing ratio of two types of steel sheets - steel with transformation-induced plasticity TRIP RAK40/70 and deep-drawing steel DC06. The limit drawing ratio of the examined materials was evaluated by a deep-drawing cup test. In the experimental research, two cups with different diameters without and with the use of lubricant were produced and compared. The examined sheets had a thickness of 0.75 mm.

In this paper I have investigated what quantum teleportation is and its implications in the creation of the quantum internet. The paper begins with a broad description of quantum mechanics and the fascinating concepts of superposition of states and quantum entanglement, and how they are fundamental to quantum teleportation. Quantum teleportation is an intriguing consequence of quantum entanglement and superposition states of qubits. It is the technique of transmitting one qubit's state to another qubit, at a completely different location, without physically transporting the qubit............

In this article, the development of an integral proportional controller (PI) is carried out, through the use of a microcontroller in order to always keep the speed stable for a direct current (DC) motor-generator system with which it counts. laboratories. For this, two stages were developed, the first involves the control stage, it consists in the development of the circuit of the ARDUINO UNO R3 board, where the PWM signal and the signal from the analog-digital converter are present, at this stage the code is made programming, which was carried out with the configuration of the PI controller, as well as the acquisition of analog signals and the emission of digital signals. The second stage is the power stage in which the power circuit, the DC motor, are immersed. in addition to the transducer. In this second stage the tuning of the speed regulator is carried out by the Ziegler- Nichols method, the stability of the machine is obtained by the trial-and-error method from the values calculated by the previously mentioned method. The speed set as a reference is 2000 revolutions per minute (rpm), either under load or idle.

Community empowerment is an effort expected to solve the economic lag of coastal and rural communities, especially the aquaculture communities. This study aims to design an empowerment model for freshwater aquaculture-based communities in South Konawe Regency, Southeast Sulawesi. Data were obtained through a survey involving freshwater aquaculture business players, experts from the Department of Fisheries and Marine Affairs, academics, and community empowerment observers. The survey was related to cultivation systems, sources of business capital, marketing systems, business management development, and forms of business institutions. The survey data were analyzed using an Exponential Comparison Method (MPE) to obtain priority options for decision-making purposes...........

Currently in the industry, induction motors represent more than 60 [%] of consumption energy of the country so it is necessary to schedule preventive maintenance to avoid interruptions in service. Within these maintenances tests are carried out that help to detect possible electrical or mechanical failures, to carry out these tests it is necessary to follow a standards-based protocol. The standards used are international standards, because the Mexican standard that corresponds to this issue is in disuse. In addition, for the In carrying out this work, different specialists dedicated to the area of maintenance, sales and regulations of electrical machines, in order to obtain results Reliable based on your industry experience.

Presented article deals with the evaluation of drawability of steel sheets. Drawability was evaluated by the normal anisotropy ratio and by mean ear height during deep-drawing with and without lubricant. In the experimental research, two types of steel sheets were examined – deep-drawing steel DC 06 and TRIP RAK40/70 steel with transformation-induced plasticity. The ratio of normal anisotropy of the examined materials was evaluated based on the tensile test results. Earing was evaluated by a cupping test on blanks with different size with punch diameter of 69.15 mm. Thickness of tested sheets was 0.75 mm.

This work shows an application in the area of programmable logic controllers (PLCs). By means of a simulation in TIA Portal, a program that reports the occupancy of a parking lot was implemented, with a maximum capacity of 12 parking spaces. To achieve this, a parking lot with 2 sensors installed was required, and with the objective of counting the number of cars entering and leaving, one sensor was installed at the entrance and another one at the exit. To inform the user about the parking lot status, two messages were required: "Parking full" and "Parking available". And as a complement, a display was needed to inform about the number of available spaces. And finally, it is important to mention that a Human Machine Interface (HMI) was required to carry out the above.
