An important role has the Paris Agreement with the aim of limiting the increase in global temperature. The commitments regarding climate neutrality within the framework of \"Fit for 55\" are important. One of the principles of how to approach the reduction of CO2 emissions within the strategies of countries, regions, cities and municipalities is the use of low-carbon strategies. As part of the study, an analysis of the input data is carried out as part of the assessment of the energy demand and efficiency of public and residential buildings, buildings of the tertiary sector, energy consumption in the public lighting sector, or the use of renewable resources in the city. The aim of the article is to determine the potential of energy savings in individual sectors and propose measures to achieve a reduction in CO2 emissions.","PeriodicalId":18723,"journal":{"name":"MM Science Journal","volume":"110 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139004547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fire is one of the main hazards associated with the operation of fuel storage tanks. Depending on the type of storage tanks, there may be a fire in the tank itself or a fire in the bund. An important factor in an actual fire is the influence of wind, which affects the geometry of the flame and thus the range of heat flux and its impact on other equipment in the vicinity of the fire. Another phenomenon known to occur in industrial fire accidents is the domino effect, where the fire can spread to other equipment and cause more severe damage. From this point of view, a systematic risk analysis is needed, where the procedures known within the SEVESO series of directives can be used. The outputs of the risk analysis and impact calculations of the consequences allow better planning for an effective and safe management of the accident. This article describes the possible consequences of an aviation fuel storage accident at an airport near which manufacturing plants and other infrastructure are located.","PeriodicalId":18723,"journal":{"name":"MM Science Journal","volume":"157 s325","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139006387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Making the right decision is necessary to ensure the organisation's competitiveness [Lestyanszka 2014a]. Organisations are trying to reduce production costs as much as possible, but this, on the other hand, brings negatives in the form of products that do not meet customer expectations. This phenomenon, however, has other downstream processes that burden the organisation and make it more difficult to continue its activities. These are customer complaints, the cost of eliminating the claimed defects, downtime, etc. [Lestyanszka 2014b, Husain 2021]. Therefore, the successful functioning of any organisation depends on its ability to adapt to changing customer requirements, as these are a priority in the market [Szander 2014, McDonnell 2013]. An effective tool for quality improvement is statistical methods and tools, which are not only advisable but essential to be implemented in production processes. Without systematic quality management, an organisation cannot grow, as it has to combine enormous efforts in developing and introducing new products with maximum quality maintenance of the already established ones.","PeriodicalId":18723,"journal":{"name":"MM Science Journal","volume":"224 4","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139006125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Cholesky factor of the permuted system stiffness matrix is reused to compute the static receptance of the workpiece for multiple cutter locations.

The article is focused on human resource management information systems (HRIS), which represent a significant part of corporate information systems. The main aim of the paper is to present the results of the analysis of HRIS used in industrial enterprises in Slovakia. The results of the analysis showed, that most often HRIS are only partially interconnected with other corporate IS. The results also pointed out that the used HRIS are considered mostly as useful and also demonstrated that how users evaluate the usefulness of the used HRIS is related to how they assess the integration of these systems with other corporate information systems.","PeriodicalId":18723,"journal":{"name":"MM Science Journal","volume":"61 5","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139003184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
