Intel Corporation set itself a goal to reduce its global-warming greenhouse gas footprint by 20% by 2012 from 2007 levels. Through the use of sustainable IT, the Intel IT organization is recognized as a significant contributor to the company’s sustainability strategy by transforming its IT operations and overall Intel operations. This article describes how Intel has achieved IT sustainability b...

Hydrological models are created for a wide range of scales and intents. The Catchment Modelling Framework (CMF) extends the Python programming language with hydrology specific language elements, to setup specific hydrological models adapted to the scientific problems and the dominant flow processes of a particular study area. CMF provides a straightforward method to test hydrological theories a...

The fractional weak discrepancy wdF (P ) of a poset P = (V,≺) was introduced in [5] as the minimum nonnegative k for which there exists a function f : V → R satisfying (i) if a ≺ b then f(a)+1 ≤ f(b) and (ii) if a ‖ b then |f(a) − f(b)| ≤ k. In this paper we generalize results in [6, 7] on the range of wdF for semiorders to the larger class of split semiorders. In particular, we prove that for ...

The fractional weak discrepancy wdF (P ) of a poset P = (V,≺) was introduced in [6] as the minimum nonnegative k for which there exists a function f : V → R satisfying (i) if a ≺ b then f(a)+1 ≤ f(b) and (ii) if a ‖ b then |f(a) − f(b)| ≤ k. In this paper we generalize results in [7, 8] on the range of the wdF function for semiorders (interval orders with no induced 3+ 1) to interval orders wit...

We used a previously developed simulation model of a plant cell wall and its enzymatic degradation to compare the abilities of two hemicelluloses, glucuronoarabinoxylan (GAX) and xyloglucan (XG), to protect cellulose microfibrils (CMFs) from attack by cellulose-degrading enzymes. Additionally, we investigated the effect of XG abundance on the degradation rate of CMFs in the presence of the same...
