Optical Packet Switched (OPS) networks are known to suffer from high packet losses due to contentions. Techniques such as fiber delay line (FDL) buffering and wavelength conversion help to relieve contentions to an extent, but are expensive and are therefore used sparingly. This paper explores how electronic edge nodes can condition the traffic entering the OPS network with the objective of uti...

In this paper we present research on applying a domain specific high-level abstractions (HLA) development strategy with the aim to “future-proof“ a key class of high performance computing (HPC) applications that simulate hydrodynamics computations at AWE plc. We build on an existing high-level abstraction framework, OPS, that is being developed for the solution of multi-block structured mesh-ba...

Previous studies of early diabetic retinopathy have shown that oscillatory potential (OP) amplitudes are reduced in many diabetic patients. OP amplitude is believed to be a more sensitive indicator of the development of future retinopathy than b-vvave amplitude of the scotopic electroretinogram (ERG). Because OPs measured to a bright white flash reflect both rod and cone system activity, it is ...

The microcirculation plays a crucial role in the interaction between blood and tissues both in physiological and pathophysiological states. Despite its critical role in numerous diseases including diabetes, hypertension, sepsis or multiple organ failure, methods for direct visualization and quantitative assessment of human microcirculation at the bedside are limited. Orthogonal polarization spe...

Objective: Organophosphorus compounds (OPs) are common causes of poisonings. Atropine and oximes are pharmacological antidotes of OPs. However, because of their adverse effects and insufficient performance, several other compounds have been evaluated as adjuvant therapy. HESA-A is a herbal-marine drug that contains material from Carum carvi (Persian cumin), Penaeus latisculatus...

We construct bivariate orthogonal polynomials (OPs) on algebraic curves of the form y m = ϕ ( x ) $y^{m} \phi (x)$ in R 2 ${\mathbb {R}}^2$ where 1 , $m 1, 2$ and is a polynomial arbitrary degree d, terms univariate semiclassical OPs. compute connection coefficients that relate OPs to basis itself whose span contains as subspace. The matrix shown be banded Jacobi matrices for 0 … N $0, \ldots N...

| This dissertation addresses performance analysis of order-picking workstations for automated warehouses. The first chapter provides a general overview of warehousing and order-picking systems (OPS). A classification of OPS is discussed. Literature regarding endof-aisle OPS, which is the type of system considered in this dissertation, is reviewed in greater detail. Typical issues for this syst...

Burkholderia mallei the etiologic agent of glanders, causes severe disease in humans and animals and is a potential agent of biological warfare and terrorism. Diagnosis and treatment of glanders can be challenging, and in the absence of chemotherapeutic intervention, acute human disease is invariably fatal. At present, there are no human or veterinary vaccines available for immunization against...

BACKGROUND A patient's perception of their illness can influence their coping ability, compliance with treatment and functional recovery. Psychological interventions to address negative beliefs may facilitate an earlier return to work. AIMS To compare perceptions of illness, fitness to return to work and time to return to work among employees with those of their occupational physicians (OPs)....

BACKGROUND The objective of this feasibility study was to gain insight into occupational physicians' (OPs) and employees' use of, and attitudes towards, 'Snelbeter' (Get Well Fast), a new web-based counselling program for employees on sick leave due to non-specific back or neck pain and their OPs. METHODS Registered user information was collected from the website to get insight in the use of ...
