An automatic custom-made procedure is developed to identify macroplastic debris loads in coastal and marine environment, through hyperspectral imaging from unmanned aerial vehicles (UAVs). Results obtained during a remote-sensing field campaign carried out the seashore of Sassari (Sardinia, Italy) are presented. A push-broom-sensor-based spectral device, onboard DJI Matrice 600 drone, was employed for acquisition data range 900−1700 nm. The platform realized by assembling commercial devices,...

Physical activity has a noticeable effect on skin blood flow and temperature. The thermal regulatory hemodynamic processes during physical are controlled by two conflicting mechanisms: the vasoconstriction induced demand to active muscles vasodilation required thermoregulation increase warm heat conduction skin. time-evolution of temperature exercise can give useful information about adaptation subject as function specific type, intensity duration exercise. In this paper, infrared...

The continuous increase in the number and scale of solar photovoltaic power plants requires implementation reliable diagnostic tools for fault detection. With recent advances low-weight, high-precision, fast-response thermal cameras, along with professional aerial platforms, infrared thermography (aIRT) is currently most popular method non-destructive, fast, relatively inexpensive monitoring (PV) plants. Typically, inspections are conducted using a UAV (drone) equipped camera to produce...

The purpose of this study was to examine the relationship between marathon performance time (MPT) and some training factors recorded for a given number weeks prior race.Twenty-two runners, age 28-54 years, participated as subjects in investigation.They kept daily exercise records during their an overall 46 races, whose ranged from 167 216 min.Among several parameters investigated, MPT found be affected mainly by mean distance run per week K, period under observation, pace P.These two have...

The purpose of this study was to investigate the effect anthropometric characteristics and training indices on marathon race times in recreational male marathoners.Training were collected for a large cohort runners (n = 126) participating Basel Switzerland between 2010 2011.Among parameters investigated, performance time found be affected by mean running speed weekly distance run during period prior body fat percentage. percentage became significant as it exceeded certain limiting value;...

Marathon (42 km) and 100 km ultramarathon races are increasing in popularity. The aim of the present study was to investigate potential associations anthropometric training variables with performance these long-distance running competitions.Training data from a large cohort marathoners ultramarathoners provided basis this work. Correlations between indices subjects race were assessed using bivariate multiple regression analyses.A combination volume intensity found be suitable for prediction...

Buoyancy-induced flows over ribbed vertical surfaces involve complex thermal and dynamic interactions between the mainstream surface texture, yielding contrasting effects on heat transfer performance of heated plate; proper analysis overall effect rate is essential for efficient operation optimization purposes. The present work pursues an insight into different factors controlling this problem. Natural convection from a plate 0.5 m height, regularly roughened with wooden transverse square...

Asymptotic homogenization is employed to formulate upscaled effective boundary conditions at a smooth virtual surface for natural-convection flow over periodically roughened vertical wall, bypass the expensive numerical resolution of and temperature fields near within wall corrugations. Microscale problems are found by expanding near-wall variables in terms small parameter $\epsilon$ , ratio between microscopic macroscopic length scales. The expressions velocity provided up second-order...
