Many research examine their specific characteristics. In order to reach a desired total torque, low torque ripple, high efficiency, many pre-plannings have to be executed. The modern age engineering industry can rely much on complex simulation software, such as MotorAnalysis – PM. In this paper, an initial IPM motor design with delta magnet arrangement was created for vehicle application. This study had a strong focus on finding correlation between rotor layout arrangement and crucial motor operationial attributes, such as: torque components, torque ripple, cogging torque and efficiency. Time stepping magnetostatics FE and time stepping transient FE simulations were used. Each arrangement changement held its own simulation file, thus the effect of each change could have been separately examined. Arrangements, where the distance between magnets is smaller, resulted in greater torque and efficiency. Usage of enlarged magnets had the same results. Size should be increased and distance should be decreased with care to avoid a growth in torque ripple.","PeriodicalId":427447,"journal":{"name":"Cognitive Sustainability","volume":"21 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123245492","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 development, among other issues, is related to increasing the level of transport efficiency and sustainability. That increase presents a challenge for the participants of intermodal transport systems. Therefore, there is a need to analyze the factors influencing the efficiency and sustainability of intermodal transport. The article aims to analyze these factors considering the viewpoint of transport chains participants. Ten factors influencing intermodal transport efficiency and sustainability were identified. The case study of Polish market was analyzed using marketing research tool. The questionary was developed, and the survey was carried out among the representatives of intermodal terminals located at seaports, rail-road terminals and forwarders. On the basis of collected information, it was possible to set the ranking of the particular factors. It was stated that efficient handling of cargo and transport means in transshipment terminals forms the most important factor from the practitioners’ viewpoint.","PeriodicalId":427447,"journal":{"name":"Cognitive Sustainability","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126339375","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 assessment is based on the green bond frameworks, the business profile of each issuer, and the publicly available data of the issuances. The study analyses the seven sectors of the green bond market (real estate, construction, mortgage banks, holding companies, manufacturing, agriculture, wholesale and retail trade). It is proven that out of the sustainable development goals (SDG), SDG 7 is the most supported one. Most issuers plan to use metrics related to pollution prevention, energy efficiency, clean transportation, and water- and wastewater management. Moreover, in four of the seven sectors involved, corporate awareness of green issues could be considered high.","PeriodicalId":427447,"journal":{"name":"Cognitive Sustainability","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122710600","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}

In recent years, reflections on green public transport have been steadily intensifying and setting new guidelines for its development focused on the environment. Gas-powered, more environmentally friendly diesel buses are used for this purpose. Part of such a transport fleet in Vilnius consists of such buses. Pollution from mobile sources is predominant in cities, so particulate matter from different gas buses (powered by CNG) was identified in this study. In this study, particle concentration measurements were performed, in which the dependence of the particle concentration on the mileage of the buses was determined.","PeriodicalId":427447,"journal":{"name":"Cognitive Sustainability","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127693465","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}

Our society transforms and changes even faster and more continuously than at any time earlier. Our work aims to define a new concept: the cognitive sustainability domain. Several fields of science were explored to recognize how the interdisciplinary approach of cognitive sustainability is valid. The former joint use of cognitivity and sustainability was reviewed in the literature as well. Results showed that digital development lets us extend our experiential cognition in most fields of our lives. Limits of the available resources and the development of cognitive functionalities are the enablers to connecting and addressing sustainability. Main dimensions and parameters of cognitive sustainability were identified, and several key research areas were defined. The structured handling of cognitive tools within sustainability results in a broader interpretation framework for analyzing, understanding and developing processes in sustainability","PeriodicalId":427447,"journal":{"name":"Cognitive Sustainability","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131416466","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}
