the main objective in sampling is to select a sample from a population in order to estimate some unknown population parameter, usually a total or a mean of some interesting variable. a simple way to take a sample of size n is to let all the possible samples have the same probability of being selected. this is called simple random sampling and then all units have the same probability of being ch...
The Caspian Sea level changes were very high in various periods of time; alternatively decreasing and increasing. Since the Caspian Sea level changes generally are remarkable in the short period of time, shoreline forward and retreat will be large due to the fluctuation of sea level; so, the prediction of shoreline changes is very important in the Caspian Sea. Bruun has presented his theory und...
Benefiting from rich agricultural land, easy transport and fishing, etc., more people are moving to live in coastal areas, with than 200 million now living areas that vulnerable extreme sea level events. Sea information is useful for societies. Image measurement rapidly developing as a new type of tool. A multicamera-based monitoring system along Japan’s coast near the Pacific proposed this pap...
abstract this study investigates the teachers’ correction of students’ spoken errors of linguistic forms in efl classes, aiming at (a) examining the relationship between the learners’ proficiency level and the provision of corrective feedback types, (b) exploring the extent to which teachers’ use of different corrective feedback types is related to the immediate types of context in which err...
many studies since 1977, in the southern coast of caspian sea revealed that the law-setback and low-lying coastal zone have been severely and increasingly impacted by rising sea-level. this rising continued until 1995. the rate of rising was nearly 13cm per year in this period (1977-1995). the general concept of setback determination is tended to introduce a buffer area between human activities...
In the past 25 years, rising of the Caspian Sea level, part of a natural treat to the sea, has inundated and destroyed many buildings and arable lands and threatened many inhabitations in coastal areas. The main reason for these damages is that the law-setback has lost its efficiency and human activities have proceeded seaward. The goal of this study is to introduce a proper setback line for th...
The focus of this study is the assessment of the main range and geophysical corrections needed to derive accurate sea level time series from satellite altimetry in the Indonesia seas, the ultimate aim being the determination of sea level trend for this region. Due to its island nature, this is an area of large complexity for altimetric studies, a true laboratory for coastal altimetry. For this ...
this study evaluates changes in species composition, catch, and cpue of three species of kilkas in the caspian sea from 1961 to 2009. the effects of fluctuations in sea level rise and fall on the catch of kilka as well as the impacts of a recent invasion by mnemiopsis leidyi (ctenophora) were assessed in terms of species composition and cpue of kilkas in the iranian coastal region of the caspia...
identification of spatial-temporal anomalies sea level pressure in iran was the main aim in this research. for this purpose six hourly data used from the to eastern longitude and to northern latitude. in this location, there are 825 pixels to geographical degree. therefore, database extent created. in this matrix, 825 are number of the pixels at that location and 90520 is number of six hourly s...
OBJECTIVES We investigated the effect of high altitude on the match activity profile of elite youth high altitude and sea level residents. METHODS Twenty Sea Level (Australian) and 19 Altitude-resident (Bolivian) soccer players played five games, two near sea level (430 m) and three in La Paz (3600 m). Match activity profile was quantified via global positioning system with the peak 5 min per...
