Therefore, land consolidation represents an area that is in extreme expansion, and which, according to the amount of funds invested in its launch and realization, represents a significant segment for the units of local self-government and the state itself. This paper deals with the analysis of the effects achieved by the land consolidation projects. Following metric data before and after land consolidation were used: number of parcels, average size of the parcel, area under the road and canal network, etc. The cadastral municipality (hereinafter, CM) Šašinci was taken as the subject municipality. In addition, for comparative analysis are used data from other CMs in Vojvodina, where land consolidation was also carried out. Based on figures and charts presented in paper, it can be concluded that the benefits of land consolidation are great. The number of parcels was reduced by an average of 59% per CM. The surface of the road and canal network increased significantly, as well.","PeriodicalId":53887,"journal":{"name":"Electronic Journal of the Faculty of Civil Engineering Osijek-e-GFOS","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135595414","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 approach used in this study has previously been utilized for fire scenarios and can be easily adapted for post-fire analysis purposes. The Minkowski sum method is utilized to generate interaction surfaces by combining multiple basic geometric shapes into a more intricate shape. In this case, the simpler shapes used are ellipsoids, and they approximate the contribution of a cross-sectional part. By dividing the section into parts, various material characteristics can be assigned to them, which is crucial for analyzing fire and post-fire bearing capacity. Once the interaction surfaces are formulated, the procedure of evaluating utilization of sections is explained based on the inputted sectional forces. The study compares the experimental and numerical results. The findings obtained utilizing this methodology demonstrate good conformity with outcomes obtained through both experimental data and finite element analysis. The investigation illustrates that fire exposure duration has the most substantial influence on compression and bending load-bearing capacity, particularly when subjected to small eccentricity.","PeriodicalId":53887,"journal":{"name":"Electronic Journal of the Faculty of Civil Engineering Osijek-e-GFOS","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135595417","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 return flow factor b was analyzed in relation to the marina entrance width, sea current velocity outside the marina (0, 1, 2, and 5 cm/s) and the sea surface level oscillation dynamics. The basic comparative parameter is the e-flushing time, Tf. The intensity of forced circulation is calculated to achieve time Tf of less than 10 days. The impact of the wind field on the e-flushing time for different marina widths was analyzed using a 3D numerical model. The numerical simulation results indicate that the e-flushing time Tf depends on the amplitude of the tidal signal, secondary to the width of the marina inlet, and the smallest amount on the velocity field in the outer region. Conversely, the return flow factor b depends on the width of the marina entrance, less on the tidal signal amplitude, and least on the current velocity outside the marina if currents are ≥ 1 cm/s. Forced circulation of 1 m3/s is only required for the marina with a smaller tidal amplitude (position Dubrovnik) to achieve Tf<10 days. If at the observed location wind is a dominant sea circulation generator, a wider marina entrance will allow faster sea exchange.","PeriodicalId":53887,"journal":{"name":"Electronic Journal of the Faculty of Civil Engineering Osijek-e-GFOS","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66266272","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}

This paper presents the results of moisture-content determination in materials used for internal thermal insulation under different hygrothermal conditions. In this study, surface and internal moisture contents were measured. Moisture sensors that enable constant monitoring of material moisture content but with different operational characteristics, were used in the analysis. The operating principle of the first method involves the conversion of the amount of infrared radiation reflected in an electric signal, and the second method involves the analysis of the electric impulse propagation velocity. The measurement results of both methods are used to determine the drying-out characteristics of components used in internal thermal insulation and the sorptive properties of the selected materials. The results of comparative studies are also presented for these proposed methods as well as the gravimetric method to determine the usability of the proposed methods in determining the dampness level. The overall measurement results helped determine the relationship between the internal and surface moisture contents and the time needed for the moisture content in different parts of the selected materials to equalize.","PeriodicalId":53887,"journal":{"name":"Electronic Journal of the Faculty of Civil Engineering Osijek-e-GFOS","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2020-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42488502","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}

This paper introduces the critical period method (CPM), which can be used for system sizing. According to this method, if the total energy production is lower than the energy demand, a critical period should be defined based on the largest difference between demand and production. The period (day) in which that difference appears is called the critical period. If the energy demand during this period is satisfied, the demand on the remaining days of the year is also satisfied. Any possible breaks in energy production, caused by a reduction in the expected river-flow rates or insolation (in the case of cloudiness), will be reduced to a minimum. The use of such a hybrid system guarantees the production of electricity throughout the year. Such a hybrid system could facilitate the realization of a smart city and help achieve energy stability and security. Despite Croatia having great potential in terms of solar energy use and the large number of available watercourses, such a hybrid system has never been realized. In particular, CPM has not been applied previously anywhere in the world.","PeriodicalId":53887,"journal":{"name":"Electronic Journal of the Faculty of Civil Engineering Osijek-e-GFOS","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2020-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44829149","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}

Different control systems and applications are used for this purpose. Efficient monitoring of DWWQ should also include the analysis of water-quality parameters, such as the range of changes and trends. The method of Rescaled Adjusted Partial Sums (RAPS) is very suitable for the visualization and determination of the readily apparent features, which may be hidden from the common time-series plots of values. This paper presents different approaches for the tracking and analysis of the DWWQ parameters using a combination of the open-source spatial database, PostgreSQL, and the open-source GIS software. The proposed approach has not yet been used in the management of communal utilities. The main advantages of this modern system are the use of opensource programs and the high efficiency of water-quality monitoring with large datasets. However, the application of this system would require further training of employees in communal utility companies. The analysis results were all obtained for real locations.","PeriodicalId":53887,"journal":{"name":"Electronic Journal of the Faculty of Civil Engineering Osijek-e-GFOS","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2020-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44487465","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}
