investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Bass-SIR model for diffusion of new products

We consider the diffusion of new products in social networks, where consumers who adopt the product can later “recover” and stop influencing others to adopt the product. We show that the diffusion is not described by the SIR model, but rather by a novel model, the Bass-SIR model, which combines the Bass model for diffusion of new products with the SIR model for epidemics. The phase transition o...

Pricing Participating Products under a Generalized Jump-Diffusion Model

We propose a model for valuing participating life insurance products under a generalized jumpdiffusion model with a Markov-switching compensator. It also nests a number of important and popular models in finance, including the classes of jump-diffusion models and Markovian regimeswitching models. The Esscher transform is employed to determine an equivalent martingale measure. Simulation experim...

A Partnership Model for Improving Service Delivery in Remote Papua New Guinea: A Mixed Methods Evaluation

Background The Community Mine Continuation Agreement Middle (CMCA) and South Fly Health Program (the Health Program) is a partnership for improving health service delivery in remote Papua New Guinea (PNG). The Health Program is delivered by a private contractor working in partnership with existing health service providers to improve service delivery using existing government systems, where poss...
