Increasing concerns about the depletion of fossil resources and the issue of environment lead to a global need for producing more clean energy from renewable sources. Ocean is appreciated as a vast source of renewable energies. Considering marine renewable energies, it can be noticed that...

Unbalanced voltage will inevitably cause power and DC voltage fluctuations in a three-phase PV system. The deterioration of power quality will do great harm to the PV panels and the loads, so it is necessary to suppress the power fluctuations. This paper further explores the coefficients control...

Chemical looping combustion (CLC) is a technique for separating carbon dioxide from flue gas. It consists of two main processes: a fuel reactor and an air reactor. In the fuel reactor, fuel reacts with solid metal oxide particles to produce heat, CO2 and H2O vapor which later can be easily...

This paper develops an integrated model for analysing regional economic development and structural change in agriculture. The input-output method allows the detailed description of a regional economy. Based on this description, regional growth pole sectors can be identified that are potential...

With the purpose of detecting the impact that variations of demand cause in the milk-cheese supply chain, and determining how the operational policies of capacity, inventories or labor force can mitigate this impact, a system dynamics simulation model has been designed based on a survey...

There has been conducted research on the theme of forecasting in construction industry. Brunch model developing is problem in forecasting. In the paper is worked out influential factor system for construction industry. General part of industry forecasting model is part of demand forecasting....

In economic literature are shown different methods and instruments of forecasting of separated factors. The most exactly from them take into account economic relations in investigation object. The paper presents the results of research conducted on forecasting in the construction industry....

This article analyzes the behavior of a producer of a legal addictive good (tobacco, alcohol or gambling) facing a demand with social interactions, especially a deterrence effect of heavy use on initiation. We simulate an epidemic model to estimate at what conditions it could be interesting for...

This article considers a process technology based on absorption for CO2 capturing of ethane gas in phase 9 and 10 of south pars in Iran using diethanolamine (DEA) as absorbent solvent. This CO2 capture plant was designed to achieve 85% CO2 recovery and obtain 19 ppm the CO2 concentration in the...

In the paper it has been analyzed specific character of building economy; developed a model of branch forecasting, forecast of construction branch in Latvia. The model consists of two parts: formation of demand and supply. The basic role belongs to demand forecasting. Demand form three...
