Making targeted subsidies and the process of releasing energy market and specified criteria for the quality of energy delivered to consumers shows the necessity for the explanation of energy production in Iran. In the meantime, thermal power plants produce about 85% of electricity in Iran. Steam and gas turbine power plants have created the vast capacity of power generation in thermal plants, b...

In this paper we analyze the impact of mutual coupling on MIMO channel capacity, considering its effect on both signal and thermal noise. We calculate noise correlation matrix in the multi-antenna system with closely spaced antenna by applying Nyquist’s thermal noise theorem. Then, we employ the noise correlation matrix in the channel capacity formula, which enables the identification of therma...

We consider the heat flux through a domain with subregions in which the thermal capacity approaches zero. In these subregions the parabolic heat equation degenerates to an elliptic one. We show the well-posedness of such parabolic-elliptic differential equations for general non-negative L∞-capacities and study the continuity of the solutions with respect to the capacity, thus giving a rigorous ...

Thermal properties are necessary for the design and control of processes and storage facilities of food materials. This study proposes the measurement of thermal properties using easily constructed probes with specific heat capacity calculated, as opposed to the use of Differential Scanning Calorimeter (DSC) or other. These probes were constructed and used to measure thermal properties of white...

In this paper we explore the tradeoffs between thermal storage capacity, cost, and other system parameters in order to examine possible evolutionary pathways for thermal concentrating solar power (CSP) technologies. A representation of CSP performance that is suitable for incorporation into economic modeling tools is developed. We also combined existing data in order to estimate the global sola...

Differential scanning calorimetry (DSC) belongs to the family of thermal analysis methods. In general thermal analysis is the determination of substance properties in dependence on temperature. Thermodynamic data (heat capacity, phase transition, enthalpy) and kinetic data can be determined by methods of thermal analysis. The greatest advantage of thermal analysis is the easy handling and the o...

the effects of pulsed electric field (pef) on the cell disintegration of sugar beet were studied. field strength (0.5kv/cm to 6kv/cm), pulse number (1 to 100 pulses) and capacity of capacitors (0.5 f to 32 f) were evaluated on degree of cell disintegration and consumed energy in pef treatment. the field conditions of 1 and 2 kv/cm, 8 f with 20 and 10 pulses respectively disintegrated the cel...

Frozen green beans (Phaseolus vulgaris, L.) thermal conductivity (k) and heat capacity (Cp) were determined experimentally by a one dimensional finite difference (transient method) and differential scanning calorimetry, respectively. Thermal properties were also estimated by the inverse problem methodology (IPM). Heat capacity and thermal conductivity behaviour with temperature were modelled by...
