    On the basis of the conducted investigations and analysis of the hard coal quality assurance process, it has been found that new IT tools need to be introduced to support the process. The study presents a system developed by the authors, which has been implemented in hard coal mines to support product quality improvement

    Contemporary enterprises when making business decisions must take many aspects into consideration. Many of them are of economic and legal nature, but some regard to environment issues. Ecology is an important factor taken into account when judging and positioning companies, and therefore owners and other stakeholders expect information about these aspects of business’ operations. Environment reporting is an important element of social accounting, which is linked to the idea of a sustainable development of enterprises

    The article focused on the role of quality control methods in designing and production processes, on the example of the automotive company, in providing a product’s parameters in accordance with a client’s requirements. Methods and tools used in a process of production, which are instruments controlling and diagnosing quality during production, were analyzed. Much attention was paid to SPC methods that statistically describe a production process

    W artykule opisano dwa przypadki uszkodzeń dźwignika hakowego kontenerowego, które miały różne przyczyny, lecz doprowadziły do powstania takiego samego obrazu szkód. Wskazano, jakie czynniki mogą doprowadzić do ich powstania, a także, które rozwiązanie techniczne w układzie hydraulicznym powoduje powiększenie skali uszkodzeń

    This article took problems about social and cultural aspect of quality management in industrial companies. This article contains theoretical considerations about idea of quality and culture of quality. In this elaboration quoted results which were carried out in thirty-one industrial companies. The results were presented in set of twenty criteria, which were taken as a tests of the quality management level. As we can notice from the tests, the most controversial and concern criteria is the level of staff motivation to realize their duties, what is the most basic condition of quality understood as fulfillment of the requirements. Generally, the level of quality management in companies was rated rather positively, the average rate of all criteria in all companies is 4.09 (four comma zero nine) in scale from 1 to 5 (one to five)

    The article deals with examples of thermography use (thermovisual measurements) to find out the technical state of belt conveyors and their equipment in open-pit mines. The measurements themselves are part of the grant project MPO FR-T11/537 “The Complex Diagnostic System for Belt Transportation”, basic output of which is a prototype of a diagnostic system on a model belt conveyor and prepared, certified and diagnostic services. All measurements are and will be verified as in situ measurements

    The economic-mathematical model of the sustainability and predictability of the transportation system and the sea ports was considered as a single model encompassing those related to the financial sustainability and predictability of the enterprises. The author substantiated the expediency of creating the models by way of the logical probability simulation. 10 indexes were suggested for the evaluation of the financial standing of individual enterprises and the entire transportation system, with the method of golden section to be applied for the determination of the appropriate regulatory value thereof. The scenario-based tentative calculations were made and the results analyzed. The author proved that the logical probability simulation makes it possible to create an economic mechanism of striking a balance between the volume of traffic and the Budget payments with no administrative control

    This paper presents some chosen results of the research conducted in the region of Łódź at the end of 2009 and at the beginning of 2010 which referred to the issues connected with the assessment of vocational risk as the main aspect of accident prevention and health prophylaxis. The analysis was carried out in the division into three groups of respondents: small enterprises, medium-sized enterprises and large enterprises. In this paper its authors are trying to answer a question what the level of abnormalities in all 200 examined enterprises is and what this level is in each of the groups separately

    This paper presents assessment methods for machinery emitting optical radiation. The method is based on described in standard PN-EN 12198 Part 1 and 2 measurements of ultraviolet, visible or infrared radiation parameters. The results of the measurements determine category of radiation emission for certain machinery. Then the example machineries where technological processes use ultraviolet, visible or infrared radiation are presente

    The interferometer-polarimeter in the stellarator W7-X will operate in the far infrared band in the double passage regime: the electromagnetic beam will be reflected back from a corner cube retroreflector and thus pass through the magnetized plasma twice. Evolution of the polarization state of the beam along the polarimeter sightline in the standard magnetic field configuration of W7-X is analyzed on the basis of differential equations, for traditional polarization parameters – azimuthal angle  and ellipticity angle . The influence of the Faraday and the Cotton-Mouton phenomena on polarization parameters  and  are analyzed. Calculations are performed for different plasma densities. Finally the potential sources of inaccuracy are considered, such as the shift in the probing beam position

    The paper presents approximations of added wave resistance useful in the early stage of designing ro-ro ferries. Reference added wave resistance values were calculated by means of SEAWAY software based on accurate numerical methods. Approximating function was elaborated by using the artificial neural networks. The model values were calculated by means of 448 ferry shape variants assuming conventional waving parameters and ferry movement parameters. Such approach permitted the replacement of the complicated numerical model with a simple analytical model based on basic hull shape parameters

    The nonlocal potential and the nearest neighbor approximation (NNA) is used to obtain a simple analytical equation for the work function. In contrast to earlier approaches to the problem, the present treatment does not involve any extra coefficients. The work function is exactly defined function of the electron density n and screening parameter kS. What is more, the presented treatment allows to calculate changes of work function when the physical dimensions of metallic sample reduces to nanoscale

    A simple analytical expression for the work function is derived on the basis of nonlocal potential and the nearest neighbor approximation (NNA). It allows to establish a direct connection between the ionization energy of atoms and their corresponding metallic crystal (work function). In consequence we can determine the screening parameter for alkali metals

    The author, a researcher at the Maritime Academy in Szczecin, has been conducting research in the field of waste management in ports of the European Union for many years. The purpose of this paper is to present the waste management system in the context of pollutants that remain in ports. The field of the research will include the ports of Szczecin and Świnoujście, which are in the close relationship with the other ports of the European Union. The results of the analysis for the years 2005–2009 were used to assess the current waste management system and can be used in practice to improve the used solutions. The system of collecting waste from ships, was represented by JSC Seaport Authority Szczecin – Świnoujście on February 1, 2004. Due to incomplete data in this study a transitional period – the year 2004 was not included. It should be emphasized, that the data analysis has not previously been published. The study was based on the latest requirements of the European Union
