sustainable and energy efficient design issues are key to the way good buildings are designed in the 21st century. no building designer today should be without the basic skills offered by the unique multidisciplinary studies of architectural design, based on energy use in buildings. however, this paper is focusing of effect of air movement on human comfort, as a key element of building design. ...

One of the evidences of erosion process in the arid regions is wind erosion. Relative flatness, poverty of the vegetation, the dominant winds and alluvial weak formation are the most important intensive factors of the wind erosion. These conditions are in the central regions and the coastal plain in the south of Iran and the enormous sands massive where have been formed, scatter are the result ...

The climatology of high wind events in the Owens Valley, California, a deep valley located just east of the southern Sierra Nevada, is described using data from six automated weather stations distributed along the valley axis in combination with the North American Regional Reanalysis dataset. Potential mechanisms for the development of strong winds in the valley are examined. Contrary to the co...

The mid-latitudes of East Asia are characterized by the interaction between the Asian summer monsoon and the westerly winds. Understanding long-term climate change in the marginal regions of the Asian monsoon is critical for understanding the millennial-scale interactions between the Asian monsoon and the westerly winds. Abrupt climate events are always associated with changes in large-scale ci...

Atmospheric ammonia concentrations were measured during fall 2001, winter, spring, and summer 2002 over natural surfaces in North Carolina where animal farms and waste storage and treatment lagoons (which are known to emit ammonia) at two heights (2 and 6m) above the surface employing an arrangement of two Thermo Environmental Instruments, Inc. Model 17C chemiluminescent nitrogen oxides (NOX)–a...

Extreme wind-driven autumn wildfires are hazardous to life and property, due their rapid rate of spread. Recent catastrophic in the western United States co-occurred with record- or near-record fire weather indices that a byproduct extreme fuel dryness strong offshore dry winds. Here, we use formal, probabilistic, event attribution analysis investigate anthropogenic influence on 2017 2018. We s...

a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...

In many arid and semiarid regions, saline playas represent a significant source of unconsolidated sediments available for aeolian transport, and severe saline dust storms occur frequently due to human disturbance. In this study, saline dust storms are reviewed systematically from the aspects of concept, general characteristics, conditions of occurrence, distribution and ecological impact. Our r...
