Introduction
https://scienceandresearch.org, is addressing some of the most important present issues of nowadays' science and is offering to you permanently updated scientific content. The nature is, at its fundamental level, far weirder and harder to understand than originally thought. The book “Links between normal scale and small scale phenomena” is giving some new useful insights and approaches, helpful to better grasp and address the quantum phenomena.

Nature has been abused for some considerable time already, and still continues to be abused. Now, nature is fighting us back, increasingly stronger for some time, and it seems clearly that we are going to lose this fight, not only because we are not intelligent enough, but rather because we are also arrogant and greedy. Corona virus pandemic is jus...

Article
The paper is presenting different dynamics of an economic complex system, based on certain assumptions made within each of the presented models in the paper. The assumptions used are allowing estimating and forecasting the evolution of the respective complex economic system. This estimation can be made in the “classical” way, which is to say withou...
Article
This paper analyses data available from the last fifty years, with regard to Earth and it has the purpose to analyze them from both perspectives: the time domain analysis and spectral-domain analysis. Following this analysis, one can conclude about the correlations within the analyzed data or about forecasted future evolution and necessary measures...

The article concerns utilization of linear regression and ANOVA for a set of data. The set of data regards the nonconformant housings of electric motors for different diameters of housings.
Article
Full-text available
The paper refers to defects recorded for asynchronous electrical motors. The aim of the paper is to conclude about the quality of the production process of the asynchronous electrical machines using the statistical process control. The main objective of statistical process control is to find and conclude about the abnormalities in the production pr...

The paper is presenting the situation of successful education mentality one uses in order to understand and to generate science when using such successful education, considerations about the role and profile of the educator but is also dealing with the link between the education and marketing, all these such as seen by the author of the paper. Keyw...

The relatively recent term of Workflow Management Technology System implies exactly a system related to the main actions on the available information and actions to take, namely the communication of information and coordination of related actions. Workflow Management Systems are capable to manage and use centralized databases and Database Managemen...
Article

The paper presents the main strength factors stressing the transverse bulkhead of a cargo ship. The transverse bulkhead is one of the main components of the hull for a general cargo vessel. There are presented the role and the importance of the general cargo vessel's type using an original drawing made in NX 8.0 Software from Siemens. Further on, w...

The authors are presenting an analysis of the work deck only for the support vessel, a ship having in its structure among others: deck cranes and helicopter deck. The work deck is one of the most important parts of the support vessel's hull. We are starting the paper by presenting the role and the importance of the support vessel's type, by using a...
Article
This paper is intended to provide a model for the study of the quality of squirrel cage induction motor, based on the Taguchi Method. By measuring the values of the considered quality characteristic - the rated current (IN) as being dependent of the control parameters: rated rotation speed (nN), rated torque (MN), rated phase voltage (UphN), effici...
Article
Full-text available
The paper aims to determine the torsional stress occurring in the rotor's shaft of the three phase asynchronous motors for a given rotational speed of the rotor. The three phase asynchronous motor is started using the main starting variants, each variant having its own torque characteristic which produces a certain maximum shear stress. The model u...

Termenul "calitate" provine din limba latina, unde "qualis" are semnificatia de "fel de a fi". Calitatea se refera la o portiune din realitatea inconjuratoare numita produs (entitate). Pentru aceasta entitate se identifica elemente semnificative, denumite caracteristici. Conceptul de calitate Termenul "calitate" provine din limba latina, unde "qual...

Nature has been abused for some considerable time already and still continues to be. Now, nature is fighting us back, increasingly stronger for some time, and it seems clearly that we are going to loose this fight, not only because we are not intelligent enough, but rather because we are also arrogant and greedy. Goals: 1) A statistical analysis in time and frequency domain of the last decades, showing how human activity has had disastrous consequences for all leaving creatures on Earth. 2) An analysis of "conventional" world economy showing how incorrect, inadequate and obsolete the concept of Gross Domestic Product (GDP) is. The subsequent conclusion that the concept of GDP, if it is not to be completely abolished, should be seriously corrected taking into account all costs 3) Possible methods and solutions to improve current situation

Nature is, at its fundamental level, far weirder and harder to understand than originally thought. The book “Links between normal scale and small scale phenomena” is giving some new useful insights and approaches, helpful to better grasp and address quantum phenomena Goal of this project: Writing a book explaining how the small scale phenomena are related to normal scale phenomena The book is concerned with the detection of links between normal scale and small scale phenomena, namely the link between the quantum world and the real world and it shows that many of quantum world rules are applying also for real world systems. The approach of the book is to explain in the first instance, in a more descriptive way, what are the reasons lying behind the writing of the book and the similarity between the quantum world and the normal scale world, analyzing and explaining why restrictive limitations of pure rationalism should be abandoned and replaced by newer, more modern and more adapted kinds of thinking. The next part represents the prescriptive part of the book, being more scientific and more technical, is concerned with providing and finding solutions, explanations and theory based prediction methods for quantum world phenomena, as well. Since there are serious limitations caused by our limited senses, perceptions and thinking (that is to say there are existing hidden dimensions for us, humans), another issue to be approached is to retrieve the information pertaining to those dimensions hidden to our senses and abilities. The competitive advantages and benefits the book offers to its readers, are: explanation of the thinking ways used to understand quantum phenomena; providing methods to model quantum phenomena; linking normal and quantum world phenomena going out from both: particularities of normal scale systems and those of quantum world phenomena
