Impact of chevron spacing and asymmetric distribution on supersonic jet acoustics and flow" (2016).

The overall design of an industrial crop production system should optimize the system's global parameters, such as total area required, intensity of cultivation and general production schedule. The key element is the optimal intensity of cultivation for the prevailing climatic and economic environments. A single-state-variable vegetative crop model (e.g. lettuce) was used to optimize a crop pro...

In recent years there has been an explosive growth in the number of wireless users, particularly in the area of mobile communication. This growth has triggered an enormous demand not only for capacity but also for better coverage and higher quality of service without increase in radio frequency spectrum allocated for mobile applications. Smart antennas dynamically adapt to changing traffic requ...

Cuvier's beaked whales (Ziphius cavirostris) were tracked using two volumetric small-aperture (∼1 m element spacing) hydrophone arrays, embedded into a large-aperture (∼1 km element spacing) seafloor hydrophone array of five nodes. This array design can reduce the minimum number of nodes that are needed to record the arrival of a strongly directional echolocation sound from 5 to 2, while provid...

When the shale gas reservoir is fractured, stress shadows can cause reorientation of hydraulic fractures and affect complexity. To reveal variation shadow with perforation spacing, numerical model between different spacing was simulated by extended finite element method (XFEM). The analyzed from two centers, fracture path, ratio length to spacing. simulations showed that rock at centers always ...

The D-spacing that is characteristic of collagen and its structural arrangement was previously thought to be a constant value. Much research is revealing that it is actually a distribution of values in biological tissues. Recent ovine experimentation has also shown that the D-spacing distribution is significantly altered following estrogen depletion. While ewes contain some major biological dif...
