The two-point method is one of the best known procedures for estimating empirical infiltration parameters from surface irrigation evaluation data and mass balance, mainly because of its limited data requirements and mathematical simplicity. However, past research have shown that the method can...

For over a decade, IT expenditure in China and Malaysia has shown a significant increase, as organisations in these countries are increasingly dependent on information systems (IS) for achieving strategic advantages and business benefits. However, there have been numerous reports of...

"In this paper we examine the impact of commodity price volatility on calorie attainment and its variability for households at the nutritional poverty line in Bangladesh. We focus on the first two moments of the distribution of calorie consumption and consider the differential impacts across...

This paper describes the new forecasting tool used by the Oesterreichische Nationalbank (OeNB) to derive near-term forecasts for GDP and imports for five Central, Eastern and Southeastern European (CESEE) countries, namely Bulgaria, Croatia, the Czech Republic, Hungary and Poland. An error...

Nowadays dynamic building simulation is an essential tool for the design of heating systems for residential buildings. The simulation of buildings heated by biomass systems, first of all needs detailed boiler models, capable of simulating the boiler both as a stand-alone appliance and as a...

In this paper gray-box models of the residential heating, ventilation and air conditioning (HVAC) system were developed. The HVAC system comprises of several subsystems such as energy recovery ventilator (ERV), air handling unit (AHU), buffer tank (BT), radiant floor heating (RFH) system, zone...

In this study, a detailed review of the performance of 24 radiative models from the literature is presented. These models are used to predict the clear-sky surface direct normal irradiance (DNI) at a 1-min time resolution. Coincident radiometric and sunphotometric databases of the highest...

The short-term behavior of borehole heat exchangers (BHE) is investigated using three 2 h test sequences each with constant inlet temperature and constant mass flow rate. Three models of the transient systems simulation program (TRNSYS) have been compared to these measurements. In order to...
