The registration of drying air parameters (temperature, humidity and velocity) along the dryer channels as well as the drying ware linear shrinkage and mass change were monitored for a month. Material and Energy balances were also recorded. Results have revealed that the drying air humidity and temperature profiles were not evenly distributed along the height of the drying tunnels. The ambient air breakthrough into the dryer was experimentally identified and quantified. It was the cause of the product quality deterioration and the reason why the critical and residual moisture in some of the products was larger than the desired one. Based on monitored data and mass and energy balances a solution was proposed for preventing the “false” air breakthrough, upgrade of the existing dryer fans and installation of the novel, measuring equipment. A hypothetical solution for increasing the capacity of the dryer, which uses the registered material and energy balances as well as factory management expectation, that the production of 50.000 masonry units per day will be achieved soon, was given also.","PeriodicalId":38009,"journal":{"name":"International Journal of Modern Manufacturing Technologies","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45266700","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 equipment is used for the experimental tracking of the behaviour of photovoltaic panels and solar thermal panels for both short and longer time intervals. The solar radiation simulation device has been developed to provide the radiation necessary for the evaluation of the efficiency and the heating of the solar panels exposed to sun. A system consisting of six OSRAM Ultravitalux 300W high-pressure lamps has been adopted, offering an optimized solution, both qualitatively and economically. The main steps achieved during its execution were: design, pre-dimensioning, verification, final dimensioning, execution and testing. According to the final tests, it was concluded that the proposed device can provide the quantitative and qualitative parameters required for solar radiation simulation in case of laboratory tests.","PeriodicalId":38009,"journal":{"name":"International Journal of Modern Manufacturing Technologies","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48621447","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 research will model a Travelling Salesman Problem (TSP). The complexity of this fundamental problem (np-hard) allows a chance to apply and develop heuristic methods and evolutionary algorithms along with exact methods (dynamic programming, branch & bound). This paper proposes a new discrete algorithm to solve the TSP based on the Particle Swarm Optimization (PSO) technique. The features of this method are fast determination through an iterative process of the optimal problem, the generalised search in all the solutions, and the avoidance of the local optimal. To avoid premature convergence, we have introduced a new operator with a new mathematical function, and we have proposed new techniques for measuring and maintaining population diversity. We tested the algorithm's performance by applying it to numerical instances and compared it to the solutions and performance provided by other evolutionary algorithms. By delaying the convergence process, the new algorithm PSO offers reasonable solutions in terms of quality comparable to those offered by different evolutionary algorithms tested. At the end of the research, we highlighted the conclusions, limitations, and new techniques based on the PSO algorithm.","PeriodicalId":38009,"journal":{"name":"International Journal of Modern Manufacturing Technologies","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42586706","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 currently accepted meaning of digitalization is the use of digital technologies to transform an object/process in order to provide new revenue and value-producing opportunities. Industry 4.0 means the entrance of industrial manufacturing into the digitalization era. This paper intends to be a contribution to the implementation of Europe’s strategy for digitalization and proposes the holonic digitalization concept introduced in manufacturing and tailored for supporting the development of the 4th industrial revolution. The implementation of manufacturing holonic digitalization consists of the accomplishment of the following four steps: sampling, holonization, digital representation of the holons, and building of holon dataset. Holonization of the manufacturing activity means its deep multi-level configuration into several stand-alone components, each component being a holon of manufacturing i.e., a sequence of manufacturing seen as a holon. The digital description of a holon refers to both holon attributes and causality, and it is obtained by holistic monitoring of the holon operation. The building of holonic cyber-tooling means to design both the flow of information and the decision-making procedure, and to build perennial cyber-tools needed to support the flow and procedure. This building lays on approaching the information processing as a decision-making process, and on the implementation of appropriate performant digital technologies.","PeriodicalId":38009,"journal":{"name":"International Journal of Modern Manufacturing Technologies","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41392944","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}

Unfortunately, the legislation in force does not allow ships to enter ports with unconventional energy sources. For this reason, unconventional energy sources will be used only during transoceanic crossings or during longer journeys. In this article major points are: 1) the influence of the FLETTNER helium Balloon on the manoeuvrability and road stability of the ship; 2) the influence of large Vertical wind turbines installed on the deck of the container ship on the manoeuvrability and road stability of the ship; 3) the calculation of the stability of the ship with the FLETTNER Balloon with helium coupled and with the 4 Vertical wind turbines installed on the ship's deck; 4) modelling the phenomena regarding the comparative analysis of the forces in the FLETTNER Balloon and in the large Vertical wind turbines. As results were obtained: 1) velocity and pressure distributions, forces and kinetic energies for the FLETTNER Balloon in various weather conditions, with winds of 10 and 20 m / s respectively from different directions: 00, 300, 600, 900 in various planes; 2) the distributions of speeds and pressures, forces and kinetic energies studied individually for each of the four large vertical wind turbines at winds of 10 m/s and 20 m/s respectively in various planes, segregated according to the position of port bow, starboard and stern port, starboard. This development was due to the growing demands to solve various problems at the industrial level, coming to the aid of many engineers who wanted an improvement in the equipment used, but did not have the financial support to perform experiments.","PeriodicalId":38009,"journal":{"name":"International Journal of Modern Manufacturing Technologies","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42362093","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 thermal conditions are decisive for the microstructure and thus the properties. In this study Ni-based powder with addition of WC particles was used laser cladding with the TruDisk 3302 laser. Tests were conducted at different energy input (heat transfer efficiency not considered). Powder was fed directly into the melt pool by a single coaxial nozzle set in front of the melt pool. The influence of basic laser cladding parameters on the geometry, microstructure and hardness was determined. The heat input of laser cladding has significant effect on chemical and phase composition, as well as microstructure. The obtained coatings have typical composite structure with NiCr metallic matrix and WC carbides. The lower energy input of laser cladding is beneficial providing limited penetration depth, dilution, and preferable distribution and high share of tungsten carbides. However, too low energy input at the chosen technological conditions will lead to the lack of fusion. The share of carbides on cross section of the coatings produced at minimum heat input is over 50%, while for the maximum heat input the share is below 20%.","PeriodicalId":38009,"journal":{"name":"International Journal of Modern Manufacturing Technologies","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47477182","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}
