Hot O and nighttime ionospheric temperatures
By analysing a large set of St. Santin F region Incoherent Scatter (IS) data for low solar activity we find nighttime ion temperature (Ti) on average to be apparently slightly higher than electron temperature (Te). We show that this difference is a bias incurred by the IS spectral analysis procedure owing to the neglect of H ions in the 300-500 km altitude region. Further, we show Te and Ti to ...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Warming Nighttime Temperatures and Crop Health in the Corn Belt
Over the last century nighttime minimum temperatures have been increasing at a faster rate than daily maximum temperatures. This warming trend has caught the attention of climatologists and agricultural scientists as they attempt to address the potential effects of elevated nighttime minimum temperatures on the health of these crops, which are so important to the U.S. economy. In this study, te...
متن کاملA Mathematical Optimization Model for Solving Minimum Ordering Problem with Constraint Analysis and some Generalizations
In this paper, a mathematical method is proposed to formulate a generalized ordering problem. This model is formed as a linear optimization model in which some variables are binary. The constraints of the problem have been analyzed with the emphasis on the assessment of their importance in the formulation. On the one hand, these constraints enforce conditions on an arbitrary subgraph and then g...
متن کاملA FUZZY MINIMUM RISK MODEL FOR THE RAILWAY TRANSPORTATION PLANNING PROBLEM
The railway transportation planning under the fuzzy environment is investigated in this paper. As a main result, a new modeling method, called minimum risk chance-constrained model, is presented based on the credibility measure. For the convenience ofs olving the mathematical model, the crisp equivalents ofc hance functions are analyzed under the condition that the involved fuzzy parameter...
