A systematic approach to robust preconditioning for gradient based inverse scattering algorithms

This paper presents a systematic approach to robust preconditioning for gradient based non-linear inverse scattering algorithms. In particular, one- and two-dimensional inverse problems are considered where the permittivity and conductivity profiles are unknown and the input data consists of the scattered field over a certain bandwidth. A time-domain least-squares formulation is employed and the i

Volcanic Aerosols in the Upper Troposphere and Stratosphere – Aircraft- and Satellite-Based Observations

Volcanic eruptions are the largest source of variability in the stratospheric particle concentration as they inject SO2 that is subsequently converted into sulphate particles. No major perturbation of the stratospheric aerosol load has been observed since the large eruption of Pinatubo in 1991, but several moderate eruptions after 2000 have caused deviations from stratospheric background condition

Innovation Barriers and Enablers that Affect Productivity in Uganda Building Industry

Abstract: The construction industry has of recent been blamed for lack of innovation. Lack of innovation in the industry is believed to be responsible for the decreasing or stagnant levels of productivity in comparison with other industries. This paper reviews the major barriers and enables to innovation in general. Propositions were made about the factors that affect innovation in the constructio
