Many high-performance, embedded applications must function in rapidly changing environments. Power/size constraints limit hardware size, while performance requirements demand algorithm-specific architectures. Reconfigurable computing devices allow the architecture to change in response to the changing environment. A model-integrated approach is used for the synthesis of these systems. The targe...

NOT only does adolescence involve changes in the endocrine function that lie at the base of much of the stormy moodiness of this period, but in addition the total body image as visualised by the youth concerned is also changing. Very often the new image is anything but complimentary. A survey by Frazier and Lisonbee1 showed that adolescent girls are very concerned about their weight. Any tenden...

In this paper we study the existence, nonexistence and multiplicity of non-negative solutions for the family of problems −∆u = λ (a(x)e + f(x, u)), u ∈ H 0 (Ω) where Ω is a bounded domain in R2 and λ > 0 is a parameter. The coefficient a(x) is allowed to change sign. The techniques used in the proofs are a combination of upper and lower solutions, the TrudingerMoser inequality and variational m...
