Battery Measurement Methods and Artificial Intelligence Applied in Energy Management Systems
428-436Views:155Diagnostics of batteries using advanced methods have gained remarkable roles in the past few years. This study focuses on the type of measurements, tests and methods to reveal and classify them. During manufacturing and operation several faults could emerge in batteries including non-optimal operation conditions, operators without experience, and finally, random changes in batteries under physical and nonphysical conditions. Improper handling of batteries and battery cells man cause operation failures or, in the worst case, accidents. To reveal these problems several methods are applied in industry and in scientific laboratories. For a comprehensive analysis of battery management, artificial intelligence and Industry 4.0 methods can be used very effectively. Big Data analysis in its standard form is not a new achievement, but other mathematical tools could be applied to control monitoring such as Fuzzy Logic or Support Vector Machine (SVM). They are efficient tools to analyse the deviation of batteries condition because it can detect sudden changes, parameter deviations and anomalies, and the user’s behaviour and habits. This article gives a description about the most important battery testing methods and the connection between Big Data and Operation Management with Artificial Intelligent (AI) methods.

Control Valve Testing During Operation
11-18Views:109The most commonly used control technology in building engineering is mixing. The purpose of the measurement is to find out what effects have the different control valve position combinations on the system. How the mixing efficiency changes in these cases.

Fraud in the Financial Sectors
1-17Views:357The competition for social resources encourages economic players to break ethical business rules to gain an economic advantage. Digitized data is making it increasingly difficult to verify their content of reality. The Wirecard scandal and the COVID-19 crisis will transform the environment around us, change our way of thinking about the world, accelerate discussions on the possible control of data produced by digitization tools, and the issue of the widest possible introduction of international accounting. Since the economic crisis of 2007, there has been a general and measurable increase in fraud in public procurements in construction industry, real estate, oil and gas, heavy industry and in mining industry, and in the financial sectors, which some governments of countries are trying to prevent it by using new tax control methods. In the stagnant economies of the economic crisis that is likely to materialize as a result of the COVID-19 epidemic, economic players will share on fewer and fewer orders, and as competition increases, the possibility or compulsion of fraud increases. Crises either begin in the financial sector or it will become one of its victims. Although financial scandals have not shaken confidence in the financial sector in recent decades, but it has violated the generally accepted public opinion that the financial sector is strictly regulated and it is non-fraudulent, non-infected area. International events affecting the financial sector have shown that internal procedures that ensure the lawful operation of a company in financial institutions have not prevented internal abuse because some of the perpetrators came from leaders.Due to the generalizations, the integrity of financial and supervisory organizations not directly involved in financial scandals are also significantly damaged, and trust can only be restored again through joint efforts, legal tightening and appropriate communication of it.

Investigating the Development Impact of the Reorganized Quality Control System on One of the Public Service Provider’s Pers
226-241Views:109At the investigated public service providers’ personal customer service they did significant changes were made in the field of quality control since April 2017. A method which existed and was used for a long time was modified, which had one of the most important objectives from a management aspect to help the development of the administrators in order to provide high quality. During our research we mostly focused the development impact of the modified system. We wanted to obtain an answer whether the new system is better for promoting the development of the administrators than the former method and to what extent administrators require feedback related to their job as well as whether this system is properly inspected and controlled by leaders. During the research we targeted three focus points related to the development aspect: self-check, constructive feedback and the degree to which seated work is controlled. Based on the results of the investigation we draft such suggestions which can promote efficiency if necessary and possibly even make the operation of the system more efficient.

Designing of Lab-scale Anaerobic Digester Equipped with Maxblend Impeller to Evaluate Effect of Mixing on Anaerobic Digestion
404-413Views:159Operational parameters can be easily controlled at lab scale experiments for an anaerobic digestion process. Our aim is to design a lab-scale digester equipped with an impeller to investigate how the geometry of impeller and different mixing modes effect the biogas yield of digester. Further, the methods of measuring the gas volume, gas composition, mixing intensity, torque, temperature are discussed in this article. The assembling of 4 liters digester is described which can be operated at various operating parameters which control the anaerobic digestion process. Mixing is very important to enhance efficiency of an anaerobic digester. To attain mixing Maxblend impeller is used in this lab-scale digester due to its better performance for mixing and power consumption. Various design consideration has been described.
