Image restoration is used to repair solar images degraded by the turbulence in Earth’s atmosphere. Restoration algorithms are based on models of the optical system that produce the images – from the solar source of radiation, through Earth’s atmosphere and telescope/instrument optics, to the detectors recording the data. In this review, these model components are discussed in the context of two...

Trespassing on the Railroad

Greater than half of all the fatal injuries on United States railroads are sustained by trespassers. The paper provides a statistical analysis of the demographics of trespassers, the activities they were engaged in, and the causes of injury. It also analyzes trends over time. The paper finds that the risks of injury and death are particularly acute for males in their 20s and 30s. The annual cas...

Railroad Crossing Heterogeneous Model

Systems are getting more and more complex and usually involve many stakeholders. Stakeholders are concerned by different aspects of the system, potentially supported by multiple Domain Specific Modeling Languages (DSMLs). The DSMLs are usually different not only in their syntax but also in their behavioral semantics. In order to provide simulation and/or verification of the overall system, it i...
