A modelling and networking architecture for distributed virtual environments with multiple servers.
… Environment System with Multiple- Servers (DVM). A DVM system shows a new paradigm of distributed virtual environments based on shared 3D synthetic environments. A variety of network elements are required to support large scale DVM systems. The network is currently the most constrained …

Analysis of High Angle of Attack Maneuvers to Enhance Understanding of the Aerodynamics of Perching
… using a computational 2D Discrete Vortex Method (DVM). Using the 2D DVM allows the ability to determine whether a low order, two dimensional code can accurately predict an actual 3D flowfield generated by highly unsteady motions. The pitching motions are studied experimentally using 3D plates in …

Behavioral Response to UVB Differs in Subalpine Populations of Daphnia Melanica
… <em>D. melanica</em>: diel vertical migration (DVM), which involves movement down the water column, and diel horizontal migration (DHM), which involves horizontal movement to shaded areas. I tested whether Daphnia from six populations varying in transparency differ in their DVM and DHM response …

The Role of Zooplankton in Regulating Carbon Export and Phytoplankton Community Structure: Integrating Models and Observations
… of zooplankton diel vertical migration (DVM) to the vertical flux of carbon as part of the biological pump. I do this by constructing and analyzing a global model that includes DVM and is driven by satellite-based estimates of primary productivity. There has long been speculation about …

Diel vertical migration and frontal variability of acoustic backscatter in the Balearic Sea
… and characterize diel vertical migration (DVM). DVM is the mass vertical movement of zooplankton and fish between the surface waters where they feed at night, and the mesopelagic zone where they avoid predators during the day; it is considered the largest migration of biomass on Earth, …

Winter vertical migration of Arctic zooplankton
… has been found of Diel Vertical Migration (DVM) in zooplankton during the Polar Night in the Arctic Ocean. However, the drivers of this behaviour during an apparent lack of illumination and food are poorly understood, as is its spatial extent across the Arctic Ocean. A novel dataset …

Use of the Discrete Vortex Method to Calculate Wind Loads over a Surface-Mounted Prism and a Bridge Cross-Section with Flaps
… aims at presenting the Discrete Vortex Method (DVM) as a tool to determine the flow field and associated wind loads over structures. Two structures are considered: the first is a surface-mounted prism and is used to simulate wind loads over low-rise structures. The second is a bridge section …

Checkpointing in distributed virtual memory by utilizing local virtual memory
… in a distributed shared virtual memory (DVM) system. DVM shares virtual memory in a loosely-coupled multi-computer system and is implemented at the software-level. The goal of this recovery strategy is to obtain a consistent recovery line that is close to the time of failure. Therefore …

Exploring circadian rhythms, food intake, and their interactions in marine invertebrates
… system to study diel vertical migration (DVM) in the copepod Acartia tonsa. DVM is driven by tradeoffs related to food availability, but we do not fully understand how food availability affects this circadian process. Using high-resolution tracking software, I find that Acartia possesses …

The effects of diel vertical migration of Daphnia on zooplankton-phytoplankton interactions
… which perform diel vertical migration (DVM) only spend the night in surface water layers but migrate downwards into the lower water layers during the day. The intention of this study was to investigate effects of DVM of Daphnia on phytoplankton dynamics and Daphnia life history …

Daphnia Diel Vertical Migration and Chemical Cues from Fish Predators
… a more pronounced diel vertical migration (DVM) at the downlake, lacustrine site (amplitude ≥8m) than the uplake, riverine site. D. pulicaria showed similar, though lower amplitude behavior. Daphnia diel migration may be controlled in part by exposure to fish predators. Daphnia should show …

A potential mechanism sustaining the biological hotspot around Palmer Deep Canyon
… migrating zooplankton, diel vertical migration (DVM) was added to particle simulations in ROMS to simulate zooplankton, using sun angle to modulate the frequency of the behavior. The addition of DVM increased simulated zooplankton residence times relative to surface residence times, with …

Broadband acoustic characterization of the deep scattering layer
… many of which undertake diel vertical migration (DVM). Despite their recognized ecological and biogeochemical significance, quantitative understanding of DSLs remains limited due to their vast spatial extent, deep habitat, complex biological composition, and dynamic coupling with ocean physics. …

An investigtion into the ability of a kinetic particle-based solver for study of gas flows in micro-scale structures
… kinetic theory based approaches, such as DVM, implement liberal approximations such as restricting the velocity space to a limited set determined through pre-cognizance or trials. Even stochastic particle approaches, such as the DSMC, usually adept at resolving such flows, proves to be …
