Isogeometric treatment of large deformation contact and debonding problems with T-splines: a review
No full textWithin a setting where the isogeometric analysis
(IGA) has been successful at bringing two different research
fields together, i.e. Computer Aided Design (CAD)
and numerical analysis, T-spline IGA is applied in this
work to frictionless contact and mode-I debonding problems
between deformable bodies in the context of large deformations.
Based on the concept of IGA, the smooth basis
functions are adopted to describe surface geometries and
approximate the numerical solutions, leading to higher accuracy
in the contact integral evaluation. The isogeometric
discretizations are here incorporated into an existing
finite element framework by using Bézier extraction, i.e. a
linear operator which maps the Bernstein polynomial basis
on Bézier elements to the global isogeometric basis. A
recently released commercial T-spline plugin for Rhino is
herein used to build the analysis models adopted in this
study
Spatial analysis of Leishmania donovani exposure in humans and domestic animals in a recent kala azar focus in Nepal.
No full textVisceral leishmaniasis (VL) is a major public health problem in the Indian subcontinent where the Leishmania donovani transmission cycle is described as anthroponotic. However, the role of animals (in particular domestic animals) in the persistence and expansion of VL is still a matter of debate. We combined Direct Agglutination Test (DAT) results in humans and domestic animals with Geographic Information System technology (i.e. extraction maps and scan statistic) to evaluate the exposure to L. donovani on these 2 populations in a recent VL focus in Nepal. A Poisson regression model was used to assess the risk of infection in humans associated with, among other factors, the proportion of DAT-positive animals in the proximities of the household. The serological results showed that both humans and domestic animals were exposed to L. donovani. DAT-positive animals and humans were spatially clustered. The presence of serologically positive goats (IRR=9.71), past VL cases (IRR=2.62) and the proximity to a forest island dividing the study area (IRR=3.67) increased the risk of being DAT-positive in humans. Even if they are not a reservoir, domestic animals, and specially goats, may play a role in the distribution of L. donovani, in particular in this new VL focus
T-splines discretizations for large deformation contact problems
No full textA T-spline-based isogeometric analysis is applied to frictional contact problems between deformable bodies in the context of large deformations. The continuum is discretized with cubic T-splines and cubic NURBS (Non-Uniform Rational B- Splines) for comparison purposes. A Gauss-point-to-surface (GPTS) formulation is combined with the penalty method to treat the normal and friction contact constraints in the discretized setting. It is demonstrated that the proposed formulation combined with analysis-suitable T-spline interpolations, is a computationally accurate and efficient technology for local and global solutions of contact problems. T-spline analysis models are generated using commercially available T-spline modeling software without intermediate mesh generation or geometry clean-up step

fuzzy logic control for dialysis application
No full textThis chapter introduces the fuzzy control approach for a dialysis session.
Due to the complexity of the human system, the classical control methods,
like PID, can fail to reach the target, mainly for what it concerns the
stabilization of the system, which can induce sudden and undesired hypotensive
collapses. To this purpose, a heuristic strategy based on expert
rules, as fuzzy logic control, can help to reach the desired performances,
reducing undesired collateral effects and increasing the potentiality of the
dialysis session
Comparative study of kala-azar vector control measures in eastern Nepal.
No full textThis study was conducted to explore the most effective vector control tool among indoor residual spraying (IRS), long lasting insecticidal nets (LLINs) and ecological vector management (EVM) as a part of the regional visceral leishmaniasis elimination initiative. Alpha-cypermethrin as IRS, PermaNet as LLINs and plastering the inner walls of houses with lime as EVM were the interventions. One baseline and three follow-up entomological surveys were carried out in all arms using CDC miniature light traps (LT) and mouth aspirators. Comparisons were made between intervention arms and control arms with pre-intervention and post-intervention vector densities. Light traps were found more efficient in the collection of Phlebotomus argentipes in comparison with aspiration. Vector densities were significantly low in both IRS arm (p=0.009 in LT and p<0.001 in aspirator collections) and LLIN arm (p=0.019 in LT and p=0.023 in aspirator collections) in comparison with control arm. However, in EVM arm, there was no significant difference in P. argentipes sand fly density in comparison with control arm (p=0.785) in LT collections in follow-up surveys. Hence, IRS was found most effective control measure to decrease vector density. LLINs were also found effective and can be considered as a promising alternative vector control tool in VL elimination initiative
