The issues of using data analysis methods to find and correct errors in the reports issued by meteorologists are considered. The features of processing various types of meteorological messages are studied. The advantages and disadvantages of existing methods of classification of text information are considered. The classification methods are compared in order to identify the optimal method that will be used in the developed algorithm for analyzing meteorological messages. The prospects of using each of the methods in the developed algorithm are described. An algorithm for processing the source data is proposed, which consists in using syntactic and logical analysis to preclean the data from various kinds of noise and determine format errors for each type of message. After preliminary preparation the classification method correlates the received set of message characteristics with the previously trained model to determine the error of the current weather report and output the corresponding message to the operator in real time. The software tools used in the algorithm development and implementation processes are described. A complete description of the process of processing a meteorological message is presented from the moment when the message is entered in a text editor until the message is sent to the international weather message exchange service. The developed software is demonstrated, in which the proposed algorithm is implemented, which allows to improve the quality of messages and, as a result, the quality of meteorological forecasts. The results of the implementation of the new algorithm are described by comparing the number of messages containing various types of errors before the implementation of the algorithm and after the implementation.

A study of the water quality of the Adolfo López Mateos Reservoir (ALMD) was developed through different indicators from a spatial and seasonal perspective. Variables related to the general characteristics of water quality, trophic level and ecological risk were assessed through the water Quality Index (WQINSF-BROWN), Trophic State Index (TSICARLSON) and the Ecological Risk Index (RIHAKANSON). Using data from physical, chemical and biological parameters obtained from four sampling points in the ALMD, the water quality was assessed in each model used. The results indicated that the reservoir presents a water quality classified as “medium” (WQINSF-BROWN = 70), where significant variations in the concentrations of some parameters are observed. The reservoir showed a general trophic state classified as “Mesotrophic” (TSIGENERAL-AVERAGE = 43.04). The ecological risk analysis achieved the best classification of the methodology, discarding contamination by heavy metals in surface waters. Through this type of applied methodologies will help as decision making tools in the dam, as well as for application in other dams in the region.

ABSTRACT: Objective: To evaluate inadequacies in Certificates of Live Birth in a city in Southern Brazil between 2011 and 2015. Methods: This is a retrospective quantitative study based on Certificates of Live Birth of mothers living in Itapema, Santa Catarina, issued from 2011 to 2015, using data from the Live Birth Information System. Results: Among 3,537 certificates, we found no mistakes in the variables newborn's sex, birth weight, maternal age, type of pregnancy, and type of delivery. Concerning incompleteness, the variable “cesarean section was performed before the start of labor” had a mean rate considered poor, while occupation was classified as good (above 6%), neighborhood as excellent (between 0.8 and 4.5%), and induction also as excellent (0.7 to 2.9%). Inaccuracies were greater in the ethnicity (up to 0.7%) and neighborhood (up to 1.3%) variables, both considered excellent. In the comparison between sections, the pregnancy and childbirth section was the most incomplete. Conclusion: Data completeness in Certificates of Live Birth was considered excellent for most variables, and the classification of inaccuracies was excellent for all variables, evidencing the quality of the information found in these certificates.

Repeatability is one of the main elements of communicating thoughts in music, so it is important to determine the quantity and quality of repeatabilities to analyze the form. We have many possible classifications of musical forms, where the moment of repeatability is reflected. However, the infinite number of possible repetitions of the same musical material makes it difficult to differentiate this aspect most accurately. At the moment there is no any classification of musical forms which would has a subtly differentiated gradation of the element of repeatability. Therefore, it is important to create a universal tool that would accurately describe this aspect in the composition. This article presents the results of a study of the influence of various methods of varying musical material on the recognition of repeated fragments of the composition. A formula is also derived that allows you to show the degree of repetition in the product in numerical terms. This will allow you to compare musical compositions in numerical terms, which will greatly facilitate the work of theorists and practitioners for whom this aspect is important. This formula is a dynamic tool, since its coefficients can be changed when conducting a more valid and extensive study. They can also be formed based on meta-analysis data. It is in this dynamism that we see the novelty and superiority of this formula over static classifications.

Adaptive solar shading systems have in comparison with the traditional systems of shading increased potential ability to improve the quality of the indoor environment and to increase the energy performance of buildings. Their extension allows all-around technological progress, but also the extensive application of large-scale glazing in building envelopes almost in all climatic regions. The literature review shows that the characteristics of the individual adaptive shading systems differ. Some have better performance in the sun protection or in improving the building's energy balance; others for example are better in glare elimination or in redistribution of daylight. The main purpose of this contribution is to provide a classification of the adaptive solar shading systems. In the article are compared merits and shortcomings of adaptive shading systems and are shortly analyzed assumptions of their wider application in central European climate conditions. Attention is also given to advantages and disadvantages, which brings the application of some kinds of adaptive solar shading systems. Several examples of adaptive shading systems are shown and briefly characterized.

We summarise various ways of performing dimensionality reduction on high-dimensional microarray data. Many different feature selection and feature extraction methods exist and they are being widely used. All these methods aim to remove redundant and irrelevant features so that classification of new instances will be more accurate. A popular source of data is microarrays, a biological platform for gathering gene expressions. Analysing microarrays can be difficult due to the size of the data they provide. In addition the complicated relations among the different genes make analysis more difficult and removing excess features can improve the quality of the results. We present some of the most popular methods for selecting significant features and provide a comparison between them. Their advantages and disadvantages are outlined in order to provide a clearer idea of when to use each one of them for saving computational time and resources.

This review of the literature is devoted to the current state of the problem of management of headache in patients with non-traumatic subarachnoid hemorrhage (NSAH). This pathology is associated with severe and prolonged headache. Despite the huge amount of references on subarachnoid hemorrhage, a little attention is paid to headache in this pathology, so it remains largely unexplored. The article presents data on the epidemiology of the syndrome, possible mechanisms of occurrence, diagnostic methods. Details of the advantages and disadvantages of drugs for anesthesia, available in the arsenal of the clinician at the moment. The results of many previously published studies are diametrically opposed, which does not facilitate the choice of tactics for effective treatment and prevention of complications. The article also identifies the problems, the solution of which, possibly, will lead to an improvement in the results of treatment of SAH and further the quality of life of the patients. The lack of evidance data on the subject suggests that the research is relevant.

The article discusses the defining competitive advantages of food retail stores. It is defined that the competitive advantages that determine the level of competitiveness of production and trade enterprises do differ. The main competitive advantages of trading enterprises are their location, product range, pricing policy and quality of service. As a result of the analysis of the trade infrastructure of the city of Lviv, it was concluded that there were problems in shaping the competitiveness of small forms of retail trade in food products, which are associated with the active development of national retail chains and the emergence of international trade operators in the market. The classification of stores by the signs of the size and territory of the girth was carried out. The peculiarities of their competitive advantages are determined. It is identified that the emergence of networks of the latest large formats of stores with the possibility of purchasing goods at lower prices was a threat to the functioning of traditional stores «close to home» and the reason for the decrease in their number. A comparative analysis of advantages and disadvantages of small forms of retail and large retail is carried out. The main competitive advantages of small retail stores are the proximity of the location to the buyer and trusting relationships with regular customers. The price, product range and possibilities of implementing loyalty programs are identified as the main strategic competitive advantages of large store formats. The emphasis on these advantages makes it possible to effectively manage the competitiveness of retail.

The quality of the analysis of the structure of merchandise exports depends on the groups of trade flows, according to which the study is carried out, therefore, the choice of the classification on the basis of which the analytical study of the export structure is carried out can give answers regarding the choice of the further direction of development of foreign trade. The article discusses the main approaches to the classification of trade flows, identifies their features, advantages and disadvantages. It has been determined that the most common of these are the Standard International Trade Classification (SITC), Lall classification used by the United Nations Conference on Trade and Development (UNCTADstat) and the International Standard Industrial Classification of All Economic Activities (ISGC) or The International Standard Industrial Classification of All Economic Activities (ISIC). The national classification of trade flows includes the Ukrainian Classification of Goods for Foreign Economic Activity (UKT FEA), compiled on the basis of the Harmonized System of Description and Coding of Goods and the Combined Nomenclature of the European Union (used in 207 countries), which promotes the closest relationship between foreign trade statistics and production statistics. Different classifications of trade flows are based on different approaches and different classification features. On the one hand, each classification should cover all groups of goods, on the other hand, show the quality component of exports. The Lall classification, which takes into account the technological complexity of exported goods, is most consistent with these two requirements. This classification is based on the available indicators of technological activity in production. It corresponds to the concept of most analysts regarding the technological rating of manufactured products. The success of a country's export directly depends on the quality of exported goods, therefore, the analysis of the structure of merchandise exports should be based on approaches that take this indicator into account.
