Context. Solar activity poses substantial risk for astronauts of the International Space Station (ISS) both on board and during extravehicular activity. An accurate assessment of the charged radiation flux in space habitats is necessary to determine the risk and the specific type of radiation exposure of ISS crew members, and to develop ways to protect future crews for planetary missions, even ...

Based on emission factors derived from the AP-42 algorithm, particulate matter from paved roads has been estimated to be a major source of PM10 of geologic origin. This is an empirical formula based on upwind-downwind measurement of PM10 concentrations and is dependent solely on the silt loading of the pavement and the weight of vehicles. A number of upwind-downwind studies conducted in urban a...

High-energy charged particles represent a severe radiation risk for astronauts and spacecrafts and could damage ground critical infrastructures related to space services. Different natural sources are the origin of these particles, among them galactic cosmic rays, solar energetic particles and particles trapped in radiation belts. Solar particle events (SPE) consist in the emission of high-ener...

the aim of this study is to investigate the effects of outside board on rm value in tehran stock exchange (tse) from the perspective of information transaction costs. to do so, a sample of 96 firms listed in tse is selected to be studied during the period of 2003-2012. tobin q ratio is used to measure rm's value and bid-ask spread for information transaction costs. in addition to these v...

We have developed novel instrumentation for making Lagrangian measurements of temperature in diverse fluid flows. A small neutrally buoyant capsule is equipped with on-board electronics which measures temperature and transmits the data via a wireless radio frequency link to a desktop computer. The device has 80 dB dynamic range, resolving millikelvin changes in temperature with up to 100 ms sam...

Size, weight, and power constrained platforms impose constraints on computational resources that introduce unique challenges in implementing localization algorithms. We present a framework to perform fast coarse localization on such platforms enabled by the compressive capabilities of Gaussian Mixture Model representations of point cloud data. Given raw structural data from a depth sensor and p...

In December 1997, a NASA rocket flew from Svalbard (Spitzbergen) carrying a scientific application computer designed at the Space Science Centre, University of Sussex. The real time science measurements performed by this board is an autocorrelation function (ACF) processing of particle count pulses as a means of studying processes occurring in near Earth plasmas. The ACF is a statistical method...

Soot emissions from automotive applications can be reduced through on-board diesel particulate filters (DPFs): the filter gets progressively loaded by filtering the soot laden flue gases, thus causing an increasing pressure drop, until an oxidative regeneration is induced by temperature rise. Due to the complexity of the involved phenomena, a fully predictive and detailed mathematical model rep...
