The future promises a cleaner and nicer world thanks to ITS (Intelligent transport systems). The day is approaching when autonomous cars will be driving on the streets. The VANET network, which is part of the ITS, was designed for this purpose. The main idea is to increase road safety. Routing protocols are very important to any network because the connection establishment depends on them. In the present work, two routing protocols used in VANET are examined and compared. These are MTP and TORA.","PeriodicalId":198420,"journal":{"name":"2022 Seventh Junior Conference on Lighting (Lighting)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116620204","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 comparison and preferences of various laser parameters based on their classification and characteristics are discussed. The main objective of this study is to reveal the dominant laser parameters for the laser ablation process to generate nanoparticles in aqueous media. The method of pulsed laser ablation in liquid to produce nanoparticles is explained in detail. The paper is divided into several main parts, starting with a brief description of various methods of nanoparticle generation and followed by how basic laser parameters and factors affect the laser ablation process. The review also discusses some results on laser ablation of nanoparticles obtained from different materials such as silver, zinc, palladium, and titanium as a function of changing the laser processing parameters of the materials. The study for understanding the process, in brief, is important as nanoparticles could be generated to be used in medicine and pharmaceuticals.","PeriodicalId":198420,"journal":{"name":"2022 Seventh Junior Conference on Lighting (Lighting)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126426295","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}

Lighting invites the passer-by to see the shop window and to experience emotions. More specifically, the study focuses on the design of lighting and how it affects the structure, organization and atmosphere of a window display so that customers are attracted to the store through the AIDA method (Awareness, Interest, Desire, Action). The relation between lighting, perception of space and consumer’s psychology are explored in order to create an atmosphere that will cause reactions and evoke emotions. A virtual window space was designed as a case study with different lighting scenarios based on the principles of Richard Kelly. A questionnaire was formed and distributed to people of various ages and backgrounds in order to investigate whether lighting design can affect the psychology of the passers-by and arise consumer’s desire to enter the store. The results focus on the four parameters of the AIDA Model: a) how fast can the lighting of a shop window attract the eye of a passer-by (Awareness), b) whether lighting can direct the gaze to a specific point in the shop window (Interest), c) the relationship between lighting and emotion, i.e. what emotion can be provoked to the passer-by with each lighting technique applied in the studied window (Desire) and d) which lighting design techniques are more likely to make people enter the store (Action)","PeriodicalId":198420,"journal":{"name":"2022 Seventh Junior Conference on Lighting (Lighting)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130227514","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}
