Ecological inference : new methodological strategies / edited
For longitudinal data, mixed models include random subject effects to indicate how subjects influence their responses over repeated assessments. The error variance and the variance of the random effects are usually considered to be homogeneous. These variance terms characterize the within-subjects (i.e., error variance) and between-subjects (i.e., random-effects variance) variation in the data....
Green Infrastructure (GI) can be used as a framework for planning human settlements and guiding development away from natural areas that possess high ecological value and provide important Ecosystem Services for society’s development. In this paper, we present a GI Plan for Yesan County (Yesan GI Plan), a small shrinking city in the Republic of Korea. Yesan possesses very rich, but still fairly...

یکی از مهم ترین عوامل موثر در وقوع آتش سوزی در مناطق خشک، پوشش گیاهی و شرایط آب و هوایی منطقه می باشد. منطقه حفاظت شده باغ شادی یکی از مناطق جنگلی استان یزد بوده که بیش ترین آتش سوزی های استان در آن رخ داده است. به منظور بررسی عوامل موثر بر وقوع آتش سوزی در این منطقه از روش تحلیل سلسله مراتبی (ahp) استفاده شد و معیارهای فیزیوگرافی شامل سه زیرمعیار ارتفاع، شیب و جهت شیب، اقلیم شامل دو زیرمعیار د...
A new multiple C-slotted microstrip patch antenna is proposed in the present study. A patch antenna is a wide-beam narrowband antenna. The microstrip patch antenna consists of a very thin metallic strip (patch) placed a small fraction of a wavelength above a ground plane. The patch can be designed in any possible shape and normally made of conducting materials such as copper or gold. This study...
Many studies have assessed the effect of landscape patterns on spatial ecological processes by simulating these processes in computer-generated landscapes with varying composition and configuration. To generate such landscapes, various neutral landscape models have been developed. However, the limited set of landscape-level pattern variables included in these models is often inadequate to gener...
Contact dermatitis is an inflammatory skin disease due to contact with different substances and caused by two mechanisms: Allergy and irritation. Contact dermatitis is a common skin disease and the most common occupational dermatosis. Differentiating between allergic and irritant contact dermatitis is essential in the identification of etiologic factor(s) and hence, its control and prognosis. T...
the effect of a distributed patch mass on the natural frequency of vibration of a laminated rectangular plate with simply supported boundaries is investigated. the third order displacement field of a composite laminated rectangular plate is defined using the two variable refined plate theory. equations of motion of the plate are obtained with the help of calculus of variation. parametric study ...
To extend coupled human–environment systems research and include the ecological effects of land-use and land-cover change and policy scenarios, we present an analysis of the effects of forest patch size and shape and landscape pattern on carbon storage estimated by BIOME-BGC. We evaluate the effects of including within-patch and landscape-scale heterogeneity in air temperature on carbon estimat...
