BACKGROUND There is only limited evidence to support care redefinition and role optimization processes needed for scaling up of a stronger primary care capacity. METHODS Data collection was based on a keyword search in MEDLINE, EMBASE and CINAHL databases. Three thousand, two hundred and twenty-nine documents were identified, 1851 met our inclusion criteria, 71 were retained for full-text ass...

Most algorithms to learn belief networks use single-link looka-head search to be eecient. It has been shown that such search procedures are problematic when applied to learning pseudo-independent (PI) models. Furthermore, some researchers have questioned whether PI models exist in practice. We present two non-trivial PI models which derive from a social study dataset. For one of them, the learn...

We develop a reuse distance/stack distance based analytical modeling framework for efficient, online prediction of cache performance for a range of cache configurations and replacement policies LRU, PLRU, RANDOM, NMRU. Such a predictive framework can be extremely useful in selecting the optimal parameters in a dynamic reconfiguration environment that performs power-shifting or resource realloca...

We present semi-analytic models of galactic outflows that are constrained by available observations on high redshift star formation and reionization. Galactic outflows are modeled in a manner akin to models of stellar wind blown bubbles. Large scale outflows can generically escape from low mass halos (M . 10 M ) for a wide range of model parameters while this is not the case in high mass halos ...

We show how the BLAS-like Library Instantiation Software (BLIS) framework, which provides a more detailed layering of the GotoBLAS (now maintained as OpenBLAS) implementation, allows one to analytically determine optimal tuning parameters for high-end instantiations of the matrix-matrix multiplication. This is of both practical and scientific importance, as it greatly reduces the development ef...

We present a general analytical model for determining the location and pattern of wrinkles in thin membranes and for making preliminary estimates of their wavelength and amplitude. A rectangular membrane under simple shear and a square membrane subject to corner loads are analysed. In the first problem, our model predicts the wavelength and the wrinkle amplitude to be respectively inversely pro...

In this paper, we study a family of analytical probability models for images within the spectral representation framework. First the input image is decomposed using a bank of filters, and probability models are imposed on the filter outputs (or spectral components). A two-parameter analytical form, called a Bessel K form, derived based on a generator model, is used to model the marginal probabi...

The ability of manipulating exible objects, such as rubber belts and paper sheets, is important in automated manufacturing systems. This paper describes a novel approach to assembly of exible objects. The operation dealt with in this paper is to assemble a rubber belt with xed pulleys. By analyzing possible states of the belt based on the empirical knowledge of the belt, we can derive a method ...

Product form queueing networks (PFQN) and generalized stochastic Petri nets (GSPN) have emerged as the principal performance modelling tools for flexible manufacturing systems (FMS). In this paper, we present integrated PFQN-GSPN models, which combine the computational efficiency of PFQN and representational power of GSPN by employing the principle of flow-equivalence. We show that FMS that inc...
