A computer-assisted method for selecting beam orientation in a one-step procedure is presented. Inverse and adjoint techniques are developed to obtain the best beam directions. Both methods rely on determining the "path of least resistance" to radiation from the tumor location to the surface of the section. The effectiveness of beam directions is then(More)
Abstract— This paper describes Galerkin finite element (FEFLOW) models for the simulation of groundwater flow in twodimensional, transient, unconfined groundwater flow systems. This study involves validation of FEFLOW model with reported analytical solutions and also comparison of reported Explicit Finite Difference Model for groundwater flow simulation(More)
Although cloud computing has increased in popularity, datacenter utilization has remained for the most part low. This is in part due to the interference that comes as a result of applications sharing hardware and software resources. When interference occurs, the resources of at least one co-scheduled application need to be reduced forcing it to take a(More)
For interstellar missions, directed energy is envisioned to drive wafer-scale spacecraft to relativistic speeds. Spacecraft propulsion is provided by a large array of phase-locked lasers, either in Earth orbit or stationed on the ground. The directed-energy beam is focused on the spacecraft, which includes a reflective sail that propels the craft by(More)
