This complex program of disturbance measurements, consisted of measurements of disturbances transmitted by conduction in the frequency range 9 kHz ÷ 30 MHz and radiated disturbances in the frequency range: 9 kHz ÷ 30 MHz, respectively. The penultimate section of the paper presents the interpretation of the measurement results, the levels of disturbances transmitted by the tested LEDs projector and an analysis of the disturbing effects on the power supply network produced by this type of LEDs projectors. In this sense, the test report performed in an existing semi-anechoic chamber (SAC) within the Low and High Voltage Testing.","PeriodicalId":405944,"journal":{"name":"2020 Fifth Junior Conference on Lighting (Lighting)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121898036","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}

Based on the Cyber-Physical Human Centric System (CPHCS), this paper proposes a novel personal comfort model framework based on CPHCS.

The goal of the paper is to discuss the role of investment into telecommunications technology on economic growth and the necessary conditions for its effective application. It presents the causal links between the climate for entrepreneurship and innovation, with particular reference to the contemporary role played by telecommunications technology in Bulgaria. The role of telecommunications technology in the modern economy and its connection to total factor productivity, as well as the barriers to the effective application of that technology, are investigated. Some of these barriers are intrinsic to the technology itself, but many are the consequence of government regulatory and legislative policies that limit entrepreneurial undertakings.","PeriodicalId":405944,"journal":{"name":"2020 Fifth Junior Conference on Lighting (Lighting)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129829742","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 companies are already actively promoting human-centric lighting. Here, the impact of chromatic light on the human brain was studied. The effects of blue, green, and red light on brain activity were compared using electroencephalography. Differences in brain activity in the occipital and central zones were analyzed. Two gender groups participated in the experiment. The frequency distribution of electroencephalographic signals for the central zone is significantly different in two gender groups. Photostimulation by chromatic light-emitting diodes initiates relatively the same signals in the occipital area. The frequency distribution of electroencephalographic signals in the central zone had a greater excitation of brain activity in blue photostimulation compared to green and red ones. This feature is noted in two gender groups. Blue light has an exciting effect on brain areas responsible for human biorhythms.","PeriodicalId":405944,"journal":{"name":"2020 Fifth Junior Conference on Lighting (Lighting)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126123216","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 resonator of the filter is implemented using a special compact square ring resonator patterned in the central conductor of a CPW transmission line. The impedance bandwidth of the proposed bandpass filter in the lower and higher frequency bands are 5.4% (10.3 to 10.87 GHz) and 11.2% (12.7 to 14.2 GHz) respectively, making this transparent filter suitable for dual-band X and Ku bands applications.
