Spray drift can be defined as the quantity of plant protection product that is carried out of the sprayed area by the action of air currents during the application process. Efficacy of pesticide applications in orchards and vineyards is highly dependent on matching the canopy characteristics with the liquid distribution on a vertical plane, this being influenced by the type of sprayer, the nozz...

This presentation concentrates on solar occultation measurements with the spaceborne spectrometer SCIAMACHY in the UV-Vis wavelength range. Solar occultation measurements provide unique information about the vertical distribution of atmospheric constituents. For retrieval of vertical trace gas concentration profiles, an algorithm has been developed based on the optimal estimation method. The fo...

Vertical electron density profile is an important source of information on the Earth’s ionosphere. It is well known that such vertical electron density profile can be retrieved using LEO (Low Earth Orbit) satellite RO (radio occultation) data. With more and more LEO satellite data available (such as CHAMP, SAC_C, GRACE, COSMIC), the retrieved vertical electron density can be more accurate if so...

When the profile information of an existing road is missing or not up-to-date and the parameters of the vertical alignment are needed for engineering analysis, the engineer has to recreate the geometric design features of the road alignment using collected profile data. The profile data may be collected using traditional surveying methods, global positioning systems, or digital imagery. This pa...

The genus Heterodera consists of 80 valid species which are distributed all over the world and they range from mono to polyphagous (Subotin et al., 2010). Several species are considered economically important (or quarantine), including H. humuli Filipjev, 1934. Previous studies on H. humuli or H. humuli as a vector of plant viruses were focused on its geographical distribution, biology, life cy...

A technique for retrieving vertical distributions (profiles) of atmospheric gas constituents from data of passive remote sensing of the atmosphere is proposed. The goal of the technique based on the statistical (Bayesian) approach to solution of inverse problems is construction of probability distribution for a sought quantity throughout the interval of the studied heights. It is assumed that i...

Our main aim in the present work is to study the influence of heat transfer analysis of thin film flows of a third grade fluid in the presence of magneto hydrodynamic (MHD) on a vertical moving belt. The momentum and energy equations are solved analytically by using the Adomian decomposition method (ADM). The results include the velocity profile, average velocity, volume flux and the temperatur...
