Barrier islands are heavily influenced by external drivers such as sea-level rise, storm-related disturbances, and other complex factors that affect net sediment exchange. Numerous ecological processes (e.g., dispersal, competition, and facilitation) interact with these drivers and ultimately influence barrier-island state change and therefore stability. Our synthesis of physical and ecological...

Dai, H.; Ye, M., and Niedoroda, A. W., 0000. A model for simulating barrier island geomorphologic responses to future storm and sea-level rise impacts. Journal of Coastal Research, 00(0), 000–000. Coconut Creek (Florida), ISSN 0749-0208. This paper presents the Barrier Island Profile (BIP) model, a new computer code developed to simulate barrier island morphological evolution over periods rangi...

The evolution of a barrier island and its stratigraphic architecture is investigated with the numerical model BIT (barrier island translation). The model simulates, with simplified equations, the effects of various processes (wind waves, storm surges, sea-level oscillations) on sediment location and characteristics. The presented formulation is able to reproduce both the cross-shore profile and...

MORTON, R.A., 2008. Historical changes in the Mississippi-Alabama barrier-island chain and the roles of extreme storms, sea level, and human activities. Journal of Coastal Research, 24(6), 1587–1600. West Palm Beach (Florida), ISSN 0749-0208. Barrier-island chains worldwide are undergoing substantial changes, and their futures remain uncertain. An historical analysis of a barrier-island chain i...

Using a multiscale approach combining continuum model with first-principles calculation, we develop a quantitative theoretical model for heterogeneous nucleation and the growth of a quantum dot molecule-a few islands "strain bonded" by a pit in heteroepitaxy of thin films, in contrast to homogeneous nucleation and growth of isolated strain islands on the surface. We show that the critical size ...

Amrum is a small barrier island on the north-west coast of Germany. The distribution of vascular plants was examined by surveying their 1km(2) grid square occupancy across the whole island. These data were used in a study on the recent vegetation change in the island. These data include 3786 observations of 450 taxa collected in two surveys in 2007 and 2008.

The lesser short-tailed bat (Mystacina t. tuberculata) has been found in 18 locations in indigenous forest in North Island since 1961, mainly in Northland kauri forest (including Little Barrier Island), on the volcanic plateau (including Tongariro National Park), Urewera National Park and in Tararua Range. In South Island this bat has only been reported once since 1961, in North West Nelson For...

پنل های خورشیدی بخش کمی از تشعشع خورشید را به الکتریسیته تبدیل می کنند، قسمت اعظم تشعشع باقی مانده به گرما تبدیل شده و دمای پنل را افزایش می دهد. با افزایش دمای سلول فتوولتائیک، بازده کاهش می یابد. در این پایان نامه برای کاهش دمای ماژول فتوولتائیک، یک واحد گرمایی با سیال عامل هوا، ساختار مارپیچ و سطح مقطع مستطیلی طراحی و ساخته می شود. واحد گرمایی در پشت پنل نصب می شود و سیستم فتوولتائیک /گرمای...
