It proposed a comprehensive set of measures to be implemented to make today's transport sector sustainable, \"smart\" and resilient in the future. The strategy identifies a number of challenges in the road sector, so the Action Plan defines a set of measures, which primarily relate to regulatory changes. This paper analyzes five such changes, which are important for the road sector, with special emphasis on the elements of change. In the context of these actions, a review was given of the potentially analogous actions envisaged by the Transport Community in its Action Plan, contained in the Strategy for Sustainable and Smart Mobility of the Western Balkans. Through the analysis of measures from these two strategies, a part of Europe's vision and plan for the future transport system is presented, while the analysis of actions at European and regional level shows future challenges expected in the road sector of Serbia, both as members of the Transport Community and as candidate countries for EU membership.","PeriodicalId":22484,"journal":{"name":"Tehnika","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71133914","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}

They are sutable for dealing with input data of various dimensions, such as signals, images and videos. Their importance is confirmed by the fact that they are used more than any other type of deep networks. This is the reason for constant development of new algorithms that improve existing models or creation od new models that accelerate or ameliorate learning process. They are utilized in a wide range of scientific and industrial fields due to their possibility of achieving high accuracy and simplicity of implementation. In this paper structure of convolutional networks is presented and, in particular, novelties in the study of convolutional layer are discussed, where different types of convolution are interpreted. Additionaly, special attention has been paid to the use of these networks in control systems in recent years, as a result of the occurrence of Industry 4.0. During scientific work analysis, convolutional networks application are divided according to the dimensionality of input data, that is, according to the dimensionality of networks and the tasks that they can solve.","PeriodicalId":22484,"journal":{"name":"Tehnika","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71134114","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}

CEO as a chief strategist 首席执行官作为首席策略师

They ignite our passion and inspire the best in us. When we try to explain why they are so effective, we talk about strategy, vision or powerful ideas. But the reality is many rewards: great leadership works through emotion. No matter what leaders set out to do-whether it's creating strategy or mobilizing teams for action-their success depends on how they do it. Even if they get everything else right, if leaders fail at this basic task of moving emotions in the right direction, nothing they do will work as it could or should. But where is the school for the person in charge of getting the best results out of all these members of the organization? There is no school for general managers - except the school of experience. CEOs have to learn on the job how to run a company, and they have to learn while all stakeholders are watching. Statistics say that over 50% of CEOs are fired in their first five years at the helm of an organization. Academic literature on strategy and strategic management mainly deals with the definitions of concepts and the process of analyzing opportunities and threats in the environment and the process of strategy development, while the process of realization and evaluation of the chosen strategy is left out and left to experts for implementation. Developing a strategy is difficult, its implementation is even more difficult, and therefore it is logical that it is a task for the most capable, for the leader, for the general manager. The CEO role is the only role in the organization that does not have a backup actor and no previews or reruns, therefore it is the most difficult role in the organization, you have to play \"for the Oscar\" on the first try; have a crystal-clear vision of the organization's future and the determination to achieve despite all obstacles. In this article, I tried to choose examples for you that indicate the importance of the unique role of the general director in the realization of the chosen strategy for the successful adaptation of the organization to changes in the environment. Only the fittest to adapt to the changes survive.","PeriodicalId":22484,"journal":{"name":"Tehnika","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71134845","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}
