This paper presents the results obtained by INMA Bucharest, following a research project, in which technology for harvesting and storing industrial hemp was developed. The equipment green stalks intended this tested an experimental plot grown with Dacia - Secuieni hemp. Operating indices (actual torque at power take-off, traction force drawbar, total effective to operate equipment, working spee...

The purpose of this research was to developed a program in visual basic software for predicting tractor implement performance combination. A conventional tillage system with mounted mouldboard plough and three bottoms used collect data from Chery (Model RM750) four-wheel drive. soil texture class were determined laboratory. Soil cone index value measured using SpotOn digital compaction meter. o...

An extension to model-based electron energy loss spectroscopy (EELS) quantification is reported to improve the possibility of modelling fine structure changes in electron energy loss spectra. An equalisation function is used in the energy loss near edge structure (ELNES) region to model the differences between a single atom differential cross section and the cross section for an atom in a cryst...

Van der Waals clusters serve as prototypical systems for studying processes of energy transfer. The I2.Ar system has attracted particular interest due to the wide array of decay processes occurring in competition with one another. Here, we present systematic dissociative photodetachment (DPD) studies of the I2- and I2-.Ar anions in the region 4.24-4.78 eV. The resulting neutral fragments are de...

A density-of-states Monte Carlo method is proposed for simulations of solid-liquid phase equilibria. A modified Wang-Landau density-of-states sampling approach is used to perform a random walk in regions of potential energy and volume relevant to solid-liquid equilibrium. The method provides a direct estimate of the relative density of states [Omega(U,V)] and thus the relative free energy withi...

In this working note, we sketch out some current thoughts on the use of “views” in a knowledge-base. A view is an explicit representation of how a general concept can be applied to a domain-specific concept. By making views explicit, we can control which, and how, more general concepts can be used to represent a domain-specific concept. We also discuss the use of views to select alternative the...

In this research, HMX energy derivatives with different carbon-containing fullerenes in different temperature conditions were studied using density functional theory. For this purpose, the materials were first geometric optimized, then the thermodynamic parameters were calculated for all of them. Then, the process of changing the energy-dependent parameters such as specific heat capacity, entha...
