Fixed-bed conversion is one of the standard methods for conversion of biofuels. However, in several cases the performance observed in applications of fixed-bed conversion of biomass and waste is far from optimal. Mathematical modeling using computational fluid dynamics (CFD) has a large...

Public universities in the Czech Republic suffer from insufficient funding for many years. One possibility for an increased funding of Czech public universities is an introduction of a low administrative fee called enrollment fee for each semester of a study. The aim of this article is to show...

A key hurdle for implementing real-time pricing of electricity is a lack of con-sumers’ responses. Solutions to overcome the hurdle include the energy management system that automatically optimizes household appliance usage such as plug-in hybrid electric vehicle charging (and discharging with...

This paper proposes an empirical method to estimate the model of sustainable profit and corporate social responsibility originated by Sudtasan and Suriya (2013). It suggests analysts to use data from official financial statements of companies which may be reported to the Stock Exchange in a...

Demand management is an important component of the emerging Smart Grid, and a potential solution to the supply-demand imbalance occurring increasingly as intermittent renewable electricity is added to the generation mix. Model predictive control (MPC) has shown great promise for controlling HVAC...

The production of regular clean fuels is faced with a problem of declining profit under more strict and costly environmental regulations. To satisfy the desire for higher profit and the firm requirements of environmental protection, it is imperative to improve the efficiency of energy systems...

Osteoporosis may be characterized by low bone density and its significance is expected to grow as the population of the world both increases and ages. Our purpose here is to model human bone mineral density estimated through dual-energy x-ray absorptiometry, using local volumetric distance...

In this paper has been shown improvement of the existing furnace for biomass combustion in the way of improving energy efficiency and meeting environmental protection criteria. One of the main problems during baled biomass combustion process is high CO emission due to incomplete combustion of...

Mathematical models have been widely used to simulate all aspects of bioenergy production systems including the growth kinetics of energy crops, conversion processes, production economics, supply logistics and environmental impacts. There is limited commercial experience to produce and process...
