The emerging tasks of determining the features of bottom sediments, including the evolution of the seabed, require a significant improvement in the quality of data and methods for their processing. Marine seismic data has traditionally been perceived to be of high quality compared to land data. However, high quality is always a relative characteristic and is determined by the problem being solved. In a detailed study of complex processes, the interaction of waves with bottom sediments, as well as the processes of seabed evolution over short time intervals (not millions of years), we need very high accuracy of observations. If we also need significant volumes of research covering large areas, then a significant revision of questions about the quality of observations and methods of processing is required to improve the quality of data. The article provides an example of data obtained during high-precision marine surveys and containing a wide frequency range from hundreds of hertz to kilohertz. It is shown that these data, visually having a very high quality, have variations in wavelets at all analyzed frequencies. The corresponding variations reach tens of percent. The use of the method of factor decomposition in the spectral domain made it possible to significantly improve the quality of the data, reducing the variability of wavelets by several times.

Derek Parfit has famously pointed out that ‘total’ utilitarian views, such as classical hedonistic utilitarianism, lead to the conclusion that, to each population of quite happy persons there corresponds a more extensive population with people living lives just worth living, which is (on the whole) better. In particular, for any possible population of at least ten billion people, all with a very high quality of life, there must be some much larger imaginable population whose existence, if other things are equal, would be better, even though its members have lives that are barely worth living. This world is better if the sum total of well-being is great enough, and it is great enough if only enough sentient beings inhabit it. This conclusion has been considered by Parfit and others to be ‘repugnant’.

It is well known that mold and casting table maintenance has a direct impact on the internal quality and surface quality of billets. In this paper, the evolution of the main key performance indicators (KPIs) associated with the main consumables of the Wagstaff Air slip billet casting technology is shown, such as molds, casting rings, transition plates and thimbles. The strategies taken to preserve a high standard of quality whilst monitoring the associated costs, are discussed. An automated Mold and Casting Table Maintenance Management system has been developed in house to make available the relevant information from the casting table servicing at the casting pit and at the mold room. A case study is described where this tool allowed us to reduce costs, keeping a high quality standard of the casting table maintenance, ensuring the internal quality of the final product.

The construction and rehabilitation of buildings and structures are intervention in the environment of people. Therefore, we are always looking for new technologies that are not only environmentally friendly but also acceptable from the point of view. Speed, flexibility, minimum limit for residents and transport, and also a high efficiency is the reason why more and more in recent years carried out the rehabilitation of sewerage using remediation sleeves. One of the systems of trenchless rehabilitation of sewerage systems used in Western Europe is a system company RELINEEUROPE Alphaliner Liner GmBH & co., the company's Technicians have developed one of the most important practices in the area of trenchless rehabilitation of sewerage systems. A large proportion of the development also has operators and owners of the pipeline. Technology offers very high quality of carried out restorations. This article describes the procedures for ensuring the quality of the used in Germany, which is a world leader in the development, production and use of this technology.

The research objective is to foster student learning activities through the TIE (Translation, Interpretation, Extrapolation) method. The research method used was descriptive correlational method. The research sample consisted of 75 people. The data instrument was in the form of a Likert scale questionnaire which consisted of the aspects of translation, interpretation, and extrapolation. Data analysis technique used descriptive statistics, Product Moment correlation, chi square normality, and Anova. The result of the study showed that the average score for translation was 3,767 which was in the high category; the average score for interpretation was 4,075 categorized as very high; and the exploration average score was 4,065 categorized as very high. Overall, it was at an average of 3,969 which was in the high category. If the translation, interpretation, and extrapolation activities were carried out properly,it could build up to 99,3% of learning activities. In conlcusion, the TIE method is important to apply in independent learning activities because it can stimulate students' cognition and psychomotor to achieve better learning quality. In addition, it can present insightful and experienced students.

AbstractWe present results of cathodoluminescence (CL) investigations of high-quality zinc oxide (ZnO) nanorods obtained by an extremely fast hydrothermal method on a silicon substrate. A scanning electron microscopy (SEM) system equipped with CL allows direct comparison of SEM images and CL maps, taken from exactly the same areas of samples. Investigations are performed at a temperature of 5 K. An interlink between sample microstructure and emission properties is investigated. CL confirms a very high quality of ZnO nanorods produced by our method. In addition, the presence of super radiation effects in ZnO nanorod arrays is suggested.
