The Photographic Part I

Part] I I

Photographic response to x-ray irradiation. I: Estimation of the photographic error statistic and development of analytic density-intensity equations.

Formulations for specular optical density as a function of incident x-ray intensity are shown to be inadequate, theoretically and compared with available data. Approximations assuming low intensities, grain densities, or energies yield significant error in typical emulsions. Unjustifiable simplifications limit analysis and consequent results. The avoidance of assumptions leads to models for rou...

The rewriting calculus - Part I

The ρ-calculus integrates in a uniform and simple setting first-order rewriting, λ-calculus and nondeterministic computations. Its abstraction mechanism is based on the rewrite rule formation and its main evaluation rule is based on matching modulo a theory T . In this first part, the calculus is motivated and its syntax and evaluation rules for any theory T are presented. In the syntactic case...

Part I : Part Ii : Part Iii : Part Iv

The theory of stick-slip is developed, based on the concept of a static and dynamic coefficient of friction. The dynamic coefficient is assumed to be independent of displacement and to depend wholly on normal stress across the surface. It is also assumed to be velocity-independent. The theory predicts that the stress drop during stick-slip is independent of machine stiffness. The displacement d...

Distal Approaches in Patellofemoral Pain: A Systematic Review, Part I

Purpose: Increased patellofemoral joint reaction force (PFJRF) is the main cause of patellofemoral pain syndrome (PFP). Foot pronation causes faulty joint coupling of the lower limb and increases the PFJRF. Therefore, the aim of systematic review is effect of the distal interventions on the clinical symptoms and kinematic of PFP patients.   Methods: The search strategy was carried out from Goo...
