[IEEE 2018 IEEE International Conference on Environment and Electrical Engineering and 2018 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe) - Palermo (2018.6.12-2018.6.15)] 2018 IEEE International Conference on Environment and Electrical Engineering and 2018 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe) - Outdoor Workers Exposed to UV Radiation: Comparison of UV Index Forecasting Methods
摘要: Ultra-Violet (UV) radiation covers only a minimal part of solar spectrum (5%) but produces severe effects on human health. Everyone is exposed to Sun but some outdoor workers categories are exposed not only in their leisure time but also during their working activities. To protect outdoor workers health, daily estimates of UV radiation are needed and without a national service providing a measured UV Index (UVI) in the Italian territory, UVI forecasting methods are welcomed. Forecasting methods can be classified in two major groups: methods based on the estimation of the UV total irradiance from solar total irradiance and methods based on regression models of measured UVIs. The former have greater uncertainties (about 30%) and are more suitable for epidemiologic studies, the latter, due to their better precision (about 10-20%), are more suitable for daily UVI evaluation.

AIP Conference Proceedings [Author(s) 3RD INTERNATIONAL SCIENCES, TECHNOLOGY & ENGINEERING CONFERENCE (ISTEC) 2018 - MATERIAL CHEMISTRY - Penang, Malaysia (17–18 April 2018)] - Durability control of UV radiation in glass fiber reinforced polymer (GFRP) - A review
摘要: Glass Fiber Reinforced Polymer (GFRP) was commonly used as outer layer, and it may expose to the ultraviolet exposure and prone to UV radiation. UV radiation will lead to degradation of the GFRP itself and it will reduce the quality and function of GFRP. This paper is a review of past studies on UV Radiation of Glass Fiber Reinforced Polymer (GFRP) in transmission line tower. A study on UV radiation toward coupling steel laminates of GFRP pultruded show the load carry the capacity of the joint was found to be increase, it was due to polymerization of the adhesives. While, a study of UV radiation on GFRP show during the aging process GFRP show signs of plasticization and after 6 months the tensile strength of GFRP show substantial descending pattern and the tensile modulus were found less affected compared to tensile strength. Glass Fiber Reinforced Polymer (GFRP) has a good potential as a material to resist UV radiation.
