One of the main research areas in Artificial Intelligence is the coding of agents (programs) which are able to learn by themselves in any situation. This means that agents must be useful for purposes other than those they were created for, as, for example, playing chess. In this way we try to get closer to the pristine goal of Artificial Intelligence. One of the problems to decide whether an ag...
one of the most important factors in study of project’s , is the study of environmental opportunities factors the permanent study of environmental opportunity factors . the study of permanent environmental changing and knowing golden threats’ cooperate with possible threats and at the result in structure forming and future skeleton of organization has a vital effects . the petrochemical industr...
abstract reception environment has considerable effects on accepting a translation. as the expectations of a target culture and its values and needs change throughout history, its criteria for accepting a translation or rejecting it will change accordingly (gentzler, 2001). the expectations of iran, as the reception environment in the present study, have changed after the islamic revolution. i...
adsorption of cyanogen molecule on the surface of pristine and sc-doped b12n12 nanocage is scrutinized using at dft calculations to investigating its potential as chemical nanosensors. the results show that cyanogen is weakly adsorbed on the pristine b12n12 and consequently its electrical properties are changed insignificantly. in order to improve the properties of the nanocage sensor, sc dopin...
The interplay between superconductivity and the charge-density wave (CDW) state in pure 1T-TiSe(2) is examined through a high-pressure study extending up to pressures of 10 GPa between sub-Kelvin and room temperatures. At a critical pressure of 2 GPa a superconducting phase sets in and persists up to pressures of 4 GPa. The maximum superconducting transition temperature is 1.8 K. These findings...
Introduction: All presolar graphite grains analyzed to date were extracted from their host meteorite using acid dissolution techniques [1-3]. However, recent studies have suggested that the use of harsh acids may significantly alter the outer surface of presolar SiC grains extracted in this way [4], and similarly may also affect graphite grains. We have previously described a technique for " ge...
Archaeology and indigenous history of Native Amazonian peoples in the Upper Xingu region of Brazil reveal unexpectedly complex regional settlement patterns and large-scale transformations of local landscapes over the past millennium. Mapping and excavation of archaeological structures document pronounced human-induced alteration of the forest cover, particularly in relation to large, dense late...
Cloud condensation nuclei in pristine tropical rainforest air of Amazonia: size-resolved measurements and modeling of atmospheric aerosol composition and CCN activity S. S. Gunthe, S. M. King, D.

The authors compare the effects of vacuum ultraviolet VUV irradiation on pristine and UV-cured low-k porous organosilicate glass SiCOH . The authors find that during VUV irradiation, more trapped charges are generated in UV-cured SiCOH as compared to pristine SiCOH. VUV is also used as a tool to investigate effects of UV curing. From comparison of VUV spectroscopy and photoinjection current of ...
