Improving the performance of composite energetic materials comprised a solid metal fuel and source oxidizer (known as thermites) has long been pursued thermites for pyrolant flares rocket propellants. The thermites, involving aluminum fuel, can be dramatically improved by utilizing nanometer-sized particles (nAl) leading to vastly higher reaction velocities, owing high surface area nAl. Despite...

The early detection and tracing of anomalous operations in battery packs are critical to improving performance ensuring safety. This paper presents a data-driven approach for online anomaly that uses real-time voltage temperature data from multiple Li-ion cells. Mean-based residuals generated cell groups evaluated using Principal Component Analysis. then thresholded cumulative sum control chart...

construction and operation of dams have two main effects on streams. at first it increases detention time and then leads to thermal stratification. changing of water quality is the result of these effects and the outflow has different physical, chemical and biological characteristics from inflow.in this study thermal regime in proposed bakhtyari reservoir was simulated with ce-qual-w2 model. th...

In the last few decades remote sensing has reached from an experimental to an operational level. The increase in the number of earth observation satellites, the advancement in tools and processing techniques, and the use of data for new applications has been phenomenal. However, the major part of the efforts were directed in the past towards the use of optical data and now also to the use of mi...

The increasing interest in the extraordinary thermal properties of nanostructures has led to the development of various measurement techniques. Transient thermoreflectance method has emerged as a reliable measurement technique for thermal conductivity of thin films. In this method, the determination of thermal conductivity usually relies much on the accuracy of heat capacity input. For new nano...

The density and viscosity values at T= (293.15 to 323.15) K for binary mixtures of nitromethane with 2-propanol, 2-butanol and 2-pentanol were measured over the entire composition range. From the experimental data, excess molar volumes, thermal expansion coefficients, excess thermal expansions, partial molar volumes at infinite dilution and deviations in viscosity were calculated. The results w...

the universal thermal climate index (utci) addresses these shortcomings by using an advanced thermo-physiological model. the aim of this study was to investigate and prepare zoning of thermal comfort condition using utci. meteorological data including temperature, wind speed, cloudiness and relative humidity were obtained on a daily time scale from 10 synoptic stations during (2004-2013) period...

The thermal and photooxidative behaviour of polyethylenes of different manufacturing histories (linear low, metallocene and high density) have been investigated by FTIR spectroscopy and the data related to the chemiluminescence (CL) and thermal analysis of the polymers. The CL intensity and activation energies for thermal decomposition were found to be dependent on the rates of oxidation of the...
