Efficient event scheduling and synchronization constitutes an essential part of high-performance parallel discrete event simulation. Traditional synchronization approaches like conservative and optimistic synchronization focus on a simple scheduling paradigm based on a primitive set of rules. However, we argue that a sophisticated synchronization algorithm considering event interactions can rem...

Although numerous species distribution models have been developed, most were based on insufficient distribution data or used older climate change scenarios. We aimed to quantify changes in projected ranges and threat level by the years 2061-2080, for 12 European forest tree species under three climate change scenarios. We combined tree distribution data from the Global Biodiversity Information ...

This paper establishes an approach to forecast air cargo demand related to terminal capacity expansion. To balance capacity and demand, it is required to forecast the future demand based on optimistic and pessimistic projections to decide when and how much, the airport should expand the capacity. System dynamics simulation model can provide reliable forecast and generate scenarios to test alter...

On Wednesday, 31 March 1999, somewhere along the border between Yugoslavia and Macedonia, three soldiers from the 1st Infantry Division were captured by Yugoslav forces, and transported to Belgrade. In the first official statements related to the incident the following morning, neither President Clinton nor Secretary of Defense Cohen referred to the three soldiers as prisoners of war. Instead, ...

The percent change in solar photovoltaic potential lost due to snow cover for the optimistic SSP126 scenarios between 2019 and 2040.

Climate negotiation outcomes are difficult to evaluate objectively because there are no clear reference scenarios. Subjective assessments from those directly involved in the negotiations are particularly important, as this may influence strategy and future negotiation participation. Here we analyze the perceived success of the climate negotiations in a sample of more than 600 experts involved i...

many large oil and gas fields in the most productive world regions happen to be fractured. the exploration and development of these reservoirs is a true challenge for many operators. these difficulties are due to uncertainties in geological fracture properties such as aperture, length, connectivity and intensity distribution. to successfully address these challenges, it is paramount to improve ...

We consider the problem of finding shortest paths on the surface of uncertain terrains. In this paper, a terrain is a triangulated 2D surface in 3D such that every vertical line intersects the surface at most once. Terrains of this type are used to represent, for example, a piece of the earth’s surface, and are typically inexact. We model their uncertainty by allowing the terrain vertices to ha...
