employees always concern about losing their job , or in other word , losing their income resources. for this purpose, every government requires strong system for covering these concerns. the unemployment insurance (ui) program’s can be used for achieving this goal. in this thesis, we price ui based on the insurance history of employee and the duration of being unemployed. we use the weibull dis...
to assess seismic hazard, it is essential to estimate the potential seismicity, particularly estimation of size of the largest earthquake that can be identified by a distinct fault or earthquake source. one of the methods applied to estimate magnitude of earthquake is use of empirical relationships between magnitude and fault parameters. fault parameters for the earthquakes from early instrumen...
background: multiple sclerosis (ms) is a neurological disease with a variety of signs and symptoms. exercise therapy has been shown to improve physical functions in ms. however, questions about an optimal exercise therapy remain. in this regard, we suggest a combined exercise therapy including aerobic and resistance exercises for ms patients. the study is designed to observe, test and compare t...
abstract in aggregate, active forms of reactive silica with mineral names are sometimes associated with sand and gravel in concrete mixture. alkali hydroxides originated from alkalis in the cement or other resources form an alkaline silica gel with this reactive silica which becomes swallowed and expanded during time causing damage to concrete. there have been growing researches on alkaline r...
Relative populations of the three energy-lowest IPR (isolated-pentagon-rule) isomers Ho@C 82 under high-temperature synthetic conditions are computed using Gibbs energy based on characteristics from density functional theory calculations (B3LYP/3-21G ∼ SDD entropy term, B3LYP/6-31G* energetics). Two major species predicted, Ho@ C 2 v ; 9-C and s ( c ); 6-C , with rather comparable supposed temp...
Dry climate, poor vegetation and relatively smooth surface and neighborhood with plain Lute are the most important factors that brought about wind erosion processes prevail in the Kerman region. Obviously, wind erosion rate and volume of material transfer depends on characteristics of speed and direction also frequency of wind as well as surface and sediment characteristics. The purpose of this...
abstract: about 60% of total premium of insurance industry is pertained?to life policies in the world; while the life insurance total premium in iran is less than 6% of total premium in insurance industry in 2008 (sigma, no 3/2009). among the reasons that discourage the life insurance industry is the problem of adverse selection. adverse selection theory describes a situation where the inf...
Abstract We investigate tropical cyclone (TC) activity and intensity within a 100 km radius of Bermuda between 1955 2019. The results show more easterly genesis over time significant increasing trends in TC (maximum wind speed (Vmax)) with decadal Vmax median value increase 30 kts from 33 to 63 ( r = 0.94, p 0.02), together August, September, October sea surface temperature (SST) 1.1 °C (0.17 p...
The study aims to determine mean annual wave heights and wind speeds in the Adriatic Sea. The Adriatic serves as a shipping route towards central Europe and a food and energy source for surrounding countries. Wave and wind climate information can serve as basis for design, research and policy making regarding ship safety and operability, potential renewable energy exploitation, design of off-sh...
The objective of this study was to assess the efficiency of three mathematical models (power, exponential and logarithmic functions) for the calculation of the horizontal mass transport (HMT), as compared to the linear spline interpolation for the Cyclone Dust Sampler (CDS) and one with a Cone (CDSC), modified Wilson and Cooke trap (MWAC) and big spring number eight (BSNE). For the purposes of t...
