Abstract This paper presents a comparison of most capable families of distributions for modelling asymmetry. Kum-normal, stable-symmetric normal family and two of the full families were chosen, where the quality of the fit, the flexibility and the amount of asymmetry parameters were factors used for comparison. The objective of this study was to generate data with increasing levels of asymmetry and to choose the best fit. The distributions were also compared in modelling two data sets of pollution of the drinking water in the El-Sharkia governorate in Egypt. Much of this paper is concerned with the distribution theory, exploring the properties of some new recent families of distributions and, where appropriate, extolling their virtues. Relatively, much of this paper is devoted to practical application.

The paper presents the results of the determination of heavy metals in drinking water samples from centralized water supply systems and wells of individual water supply of the Sverdlovsk region. It was found that the content of copper ions in the samples does not exceed its maximum permissible concentration, and the content of lead and cadmium ions in most samples is higher than the permissible norms. It is established that water samples from Nizhny Tagil and Serov are more contaminated with cadmium. The causes of drinking water pollution are discussed. It was found that the pollution of water from the centralized water supply systems with heavy metals is mainly due to the non-compliance of the operated water pipes with sanitary and hygienic requirements. Groundwater pollution is caused by the infiltration of industrial effluents containing heavy metals from storage and sedimentation tanks through soil. It is shown that numerous industrial enterprises in the Sverdlovsk region aggravate the process of pollution of surface and groundwater with heavy metals. The unsatisfactory quality of water in terms of the content of heavy metals in Sverdlovsk region is revealed. The authors dwell on the need to continue research to determine the content of other heavy metals in water and expand the geography of sampling in the region in order to assess more accurately the quality of water.

The study was carried out in Ungaran. The goals of this study are to know and to evaluate the potential spring to add drinking water of Ungaran population. This study uses observation and secondary data analysis. The collected data are meteorology data, the water production of Municipal waterworks, the quality and the quantity of springs, the number of population and the customers. The result of the study shows that there are eight springs with the total debit 157 liter/ second or 6739 m3/ day. The Municipal Waterworks uses 65 liter/ second or 5616 m3/ day with the leaking rate 7% or 5222,88 m3/ day and the rest is used for irrigation. The quality of spring is qualified for drinking water requirement. The need of drinking water for per capita of the population is 136.7 liter/ capita/ day. In 2003 the prediction of the number of consumers is about 20.745 persons, so the total need of drinking water is predicted about 2835.8 m3/ day. The total need of drinking water added with the leak water is 3032.36 m3/ day. The Municipal Waterworks fulfils the need of drinking water for the population especially for the consumers of Municipal Waterworks. However, if the number of customers is accounted based on the number of the population in the pipe sope (­+ 48246 persons), the Municipal Waterworks will not fulfil the need of drinking water for population, therefore it needs to add volume production of drinking water.

The paper discusses advantages and disadvantages of existing methods for determining water quality. It proposes to use electro-kinetic capacity as a key indicator together with cluster analysis of obtained results. It is shown, that according to such indicators as pH, turbidity, alkalinity, general rigidity, content of ion Ca2+, Mg2+, the quality of drinking water in Samara is stable and consistent with existing standards. The research reveals some zeta-potential (ZP) dependence on water pollution density. It was shown that the link between zeta-potential and various kinds of contamination in drinking water is underexplored and requires further detailed study.

Sequencing Procedure

Species origination and extinction events far outnumber radioisotopically dated events in the ancient stratigraphic record. In order to calibrate rapid rates of Mesozoic and Paleozoic change and to estimate the ages of paleobiologic events it would be ideal to have multiple dated events in single stratigraphic sections. This condition is rarely realized and the practical alternative is to build composite sections that combine information from many different locations. The compositing process takes advantage of all available evidence of relative age to produce high resolution time lines; i.e. ordered sequences of individual events whose average spacing is much finer than the duration of biostratigraphic zones and can approach the uncertainty intervals of the highest precision radioisotopic dates. Dated events are included in the compositing process from the outset. As a result the sequencing procedure is more efficient and the dated events find their optimal positions in the time line independent of any biostratigraphic zonal schemes. The sequencing procedures follow simple logical rules that may be learned from tiny data sets. When usefully large numbers of events are involved, however, the sequencing must be undertaken by computer and there is seldom a unique solution that best fits the field data. The range of positions in sequence that an event may occupy across the full set of equally best-fit solutions is a measure of the resolving power of the event. As new high-precision dates and detailed range charts continue to become available, the quality of the time lines will improve and they will become increasingly viable alternatives to zonal time scales in the older parts of the Phanerozoic.

Ship Performance

An overview of data veracity issues in ship performance and navigation monitoring in relation to data sets collected from a selected vessel is presented in this study. Data veracity relates to the quality of ship performance and navigation parameters obtained by onboard IoT (internet of things). Industrial IoT can introduce various anomalies into measured ship performance and navigation parameters and that can degrade the outcome of the respective data analysis. Therefore, the identification and isolation process of such data anomalies can play an important role in the outcome of ship performance and navigation monitoring. In general, these data anomalies can be divided into sensor and data acquisition (DAQ) faults and system abnormal events. A considerable amount of domain knowledge is required to detect and classify such data anomalies, therefore data anomaly detection layers are proposed in this study for the same purpose. These data anomaly detection layers are divided into several levels: preliminary and advanced levels. The outcome of a preliminary anomaly detection layer with respect to ship performance and navigation data sets of a selected vessel is presented with the respective data handling challenges as the main contribution of this study.

Introduction. Until 2014, water supply in Sevastopol city and its municipal districts was combined due to its own surface and underground waters as well as a water conduit running from the Mezhgornoye reservoir located in the Saksky district and filled with the Dnieper waters of the North Crimean Canal. After 2014, this source was shut off. Therefore, it became important to conduct a comparative analysis of the quality of drinking water supplied to the settlements of this territorial entity. Purpose of the study: The study is aimed to assess the quality of drinking water and perform its analysis in Sevastopol city and nearby settlements, taking into account the increase in water intake from rivers and underground sources in recent years. Methods. Objects of the study are surface and underground water supply points, and drinking water for consumers. We used standard methods for the analysis of drinking water with an assessment of its physical, chemical and sanitary-bacteriological indicators using analysis of variance (AoV) methods. Water quality was assessed by the specific combinatorial index of water pollution. Using GIS technologies, maps were built to visualize a number of indicators: chemical oxygen consumption and data on the water pollution complexity coefficient at the stage when consumers receive water from the central water supply system (for all municipal districts). Results. It was established that sanitary and microbiological indicators of tap water quality — by the total microbial count, total coliform bacteria and thermo-tolerant coliform bacteria — immediately before being fed to the central water supply system in the Southern and Northern districts of Sevastopol, did not exceed sanitary standards. Due to the considerable length of the distribution networks and their high deterioration, secondary pollution of drinking water is currently taking place. In a number of municipal districts, it was revealed that the key indicators being assessed exceeded the norms of the State Sanitary Rules and Regulations. For the first time, with the help of GIS technologies in the ArcGis 10.4 software shell, specific ranks of drinking water pollution levels were distinguished for individual municipal districts, which made it possible to visualize the dynamic characteristics of polluting ingredients taking into account their territorial affiliation.
