This work presents trends and comparisons that show a change in the consumption and production of video games in times of confinement due to the health emergency. The video game industry has modified its philosophy and adapted its products to the new requirements and trends of consumers who see in this activity a way to appease the psychological and social impact due to quarantine and isolation. There is evidence of a 65% increase in the use of online video games, which has broken a world record. Products that have new aspects and considerations never before proposed by this great industry have been developed and offered, such as thematic games related to the COVID-19 pandemic.
Abstract This work presents trends and comparisons that show a change in the consumption and production of video games in times of confinement due to the health emergency. The video [...]

This technical note summarizes a technical comparison of common testing procedures, as well as reviewed of the UN Test N` 5, for the assessment of the self-heating properties of cargoes and materials that has shown a clear trend on maritime fire and explosions events, as well as considering of external factors that can combine self-heating and emit flammable gases to conclude in an unlikely event affecting the security of crews and ships. A high understanding of the external factors effect on the cargo materials certainly will help the application of spontaneous reactions management actions (SRMA) on board of ships during the cargo sea passage. The intended comparison is based on laboratory, industry and field observations and data, whereas the among the external factors considered are, moisture content, stockpile procedure and aging, air velocities and moderate pressures internal and externally to the cargo material. The comparison results have shown that the self-heating and the flammable gas emissions has a common pattern when reacting with any oxygen available source, regardless the reactive material chemical composition.
Abstract This technical note summarizes a technical comparison of common testing procedures, as well as reviewed of the UN Test N` 5, for the assessment of the self-heating properties [...]
Second order systems are those that respond to a second order differential equation. The study of a second order system is proposed, given by an RC electric circuit. The transfer equation was determined and the transient response was analyzed using the method of the Geometric Place of the Roots, likewise the coefficients of the PID controller were determined. From the response of the PID controller, a backpropagation neural network was created and trained to later replace the classic PID controller. In this work, the analysis of a PID controller case study is carried out where an artificial neural network has been implemented to evaluate its response. It is observed that the results are acceptable and with a good transient response.

In this work, the design of a robotic hand with 7 degrees of freedom is presented that allows greater flexibility, achieving the usual actions performed by a normal hand. The work consists of a prototype designed with linear actuators and myoelectric sensor, following the mechanism of the University of Toronto for the management of functional phalanges. The design, construction description, components and recommendations for the elaboration of a flexible and useful robotic hand for amputee patients with a residual limb for the socket are presented.

This research work will address business issues and related to social responsibility. Likewise, a comparison will be made between continents to know the different aspects according to the location of the companies and their participants. In the same way, an analysis will be approached mentioning different definitions regarding this topic and the role of an industrial engineer in these aspects. After arguing and overcoming all the issues about socially responsible companies, an example will be presented that meets all the previously established points. Before concluding, from the social point of view, possible scenarios in which the implementation of corporate social responsibility could be feasible will be illustrated and finally the factors that influence organizations or companies to fail to comply with social responsibility will be established.
Abstract This research work will address business issues and related to social responsibility. Likewise, a comparison will be made between continents to know the different aspects [...]
The analysis of a research work developed in the company C.V.G CARBONORCA of Venezuela is presented, which has two gas purification plants for the cooking area, designed to purify the gas that comes from the cooking ovens. Each plant is made up of solenoid valves, pneumatic valves, transmitters, process mimic panel and a supervisory system. All these elements are governed by a SIEMENS S5-115U PLC which is in a state of obsolescence, which is why the replacement of these automata by ALLEN BRADLEY ContolLogix automata was designed, in order to guarantee continuity in operations in plant. The research was done with a descriptive design of the field experimental type. A code for each gas treatment plant was obtained in RSLOGIX 5000 v17.00.00 and the update of the database of the supervisory system. The operation of the program was also verified through a simulation of the plant in a supervisory system, the deployment of which was designed for this purpose.

This article presents the Analysis of Partial Discharges using Neural Techniques. Rotating machines used in industry tend to have insulation failures caused by lack of maintenance and ignorance of their status. It is important to carry out periodic tests and continuous evaluations of the state of the insulation to guarantee the correct operation of the machines. One of the methods used to detect these faults is Partial Discharge. Which consist of small discharges produced in a portion of gas that is dissolved in the oil or dielectric that constitutes the insulation of electrical machines. In this research work, an analysis of two works developed around partial discharges is carried out, where artificial intelligence techniques have been implemented. The results showed a high effectiveness of neural networks to achieve the classification ofpartial discharges and contribute to the maintenance of high-power electrical equipment.

The purpose of this work is to study the relation and the effect of nitrogen in the reducing gas mixture used in the isothermal reducibility testing of the iron oxide by planning and carried out using ammonia gas so that its decomposition produces 15% H2 and N2 gases. Ammonia gas also 6% by volume was added to a gas flow containing 28% H2 y 68% N2 by weight so that obtain a final gas composition of 30% H2 and &0% N2. This reinterpretation of the test data allowing the comparison of reducibility test reducibility in such a way to compare the nitrogen effect on swelling of iron oxides undergoing reduction. The comparison was made based on the theoretical estimation of nitrogen absorption, the fresh metallic iron formation during the hematite-magnetite-Wustite so produced and the abnormal volume increase of the considered samples. It was also possible to empirically relate and compare the studied effects of nitrogen content from different sources but gas such as solid carbon containing reducers such as coal.
