Many studies have explored outdoor thermal comfort during the last several years, ever since it has been strongly related to human health and well-being. The physiological equivalent temperature (PET) is one of most commonly used indexes. It approved applied within different urban spaces climates. This study a comparative research that importance using mean radiant (Tmrt) in PET assessment by e...
Green infrastructure can improve thermal comfort in outdoor urban spaces in moderate climates. The impact of green spaces on thermal comfort is often exclusively investigated through meteorological variables and human-biometeorological indices. Yet, studies on perceived thermal comfort are scarce. As thermal comfort is a property of human perception of the thermal environment, this knowledge is...
in this thesis, a new optically active poly(amide-imide) (pai) was synthesized by the indirect polycondensation reaction of the l-phenylalanine based diacid chloride and 4,4?-diaminodiphenylether in the presence of triethylamine in n-methyl-2-pyrrolidone. the formation of pai was confirmed by ftir, 1h nmr and elemental analysis. in next step, the surface of titanium dioxide (tio2) nanoparticles...
Many studies were investigated to grade outdoor thermal comfort and related sensation during the past years. This study aims explore conditions in hot Mediterranean climate (Csa), which annually includes 1100–1700 cooling degree days 1200–1800 heating (CDD = 1100–1700, HDD 1200–1800). research tested human by applying Physiological Equivalent Temperature (PET) index. A field survey of 1230 inte...
Urban residential building layouts have an impact on air temperature and thermal comfort. Research has shown that poorly designed can lead to discomfort. Thus, it is crucial analyze the relationship between temperature. We used ENVI-met 3D microclimate model simulate six typical explore diurnal seasonal variations in In addition, we physiological equivalent (PET) as evaluation index for comfort...
Background and Aim: Combined exposure to noise and temperature can affect the neurophysiological responses of the office staff. The present study was done to investigate the impacts of combined exposure to noise and low air temperature on physiological responses and environmental comfort. Methods: In this experimental study, the studied population included the students who were randomly selecte...
In this study, we collected 927 cases of samples from students at the Harbin Institute Technology, China and conducted a thermal comfort questionnaire survey on four outdoor exercise modes in winter. Additionally, analyzed perception conditions campus population winter, association between volume TCV (Thermal Comfort Vote) correlation PET (physiological equivalent temperature) MTSV (Mean Therma...
a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
