Present day tropospheric ozone and its changes between 1850 and 2100 are considered, analysing 15 global models that participated in the Atmospheric Chemistry and Climate Model Intercomparison Project (ACCMIP). The ensemble mean compares well against present day observations. The seasonal cycle correlates well, except for some locations in the tropical upper troposphere. Most (75 %) of the mode...

An extension of the Disjunctive Model, eeciently representing Jobshop Scheduling (JS) problem, to more general Resource-Constrained Project Scheduling (RCPS) problem is proposed. The extension considers diierent groups of resources used by activities in diierent amounts limited to a constant value in every moment of the project duration. A solution to the problem is represented by a project res...

We generalize and unify some aspects of the work of I. Daubechies, J.C. Lagarias [Linear Algebra Appl. 162 (1992) 227–263] on a set R of matrices with right-convergent-products (RCPs). We show that most properties of an RCP set R pass on to its compactification R (i.e., its closure in the matrix space). Results on finite RCP sets generally hold for compact RCP sets, among which is the existence...

The formal model of recursive communicating processes (RCPS) is important in practice but does not allows to derive decidability results for model checking questions easily. We focus a partial order representation of RCPS’s execution by graphs—so called run graphs, and suggest an under-approximative verification approach based on a bounded-treewidth requirement. This allows to directly derive p...

There are notable differences between the real problems of scheduling and the theoretical patterns. This paper develops an algorithmic approach to the scheduling of aircraft maintenance, taking into account the operating conditions imposed by the maintenance company. The basic differences with regard to RCPS stem from the following factors: the variation between morning and afternoon shifts; th...

the present study modeled how future terrestrial net primary productivity (npp) changes spatiotemporally for the eastern mediterranean biomes of turkey using carnegie ames stanford approach (casa) model, moderate resolution imaging spectroradiometer (modis) data, the four regional climate change scenarios (rcp 2.6, rcp 4.5, rcp 6.0 and rcp 8.5), and such ancillary data as percent tree cover, la...

Abstract The breeding of heat-tolerant (HT) varieties is considered an effective adaptation measure to reduce the impacts global warming on crops. However, little known about how much heat tolerance needs be attained in HT and by when should introduced a climate. Here, we assessed effect introduction rice incidence low-quality grains (chalky grain, CRG, as result high temperatures), formulated ...

Precipitation and temperature data of Tigray region Ethiopia for baseline (1950-2000), future climate projection mid-century (2050) end-century (2070) based on medium emission scenario (RCP 4.5) high 8.5) were obtained from model ensembles, Coupled Model Intercomparison Project 5 (CMIP5). Arc GIS 10.1 Diva 7.5.0 was used mapping climatic variables area coverage. Area coverage computed number ce...

This study considers and compares several of the most important factors contributing to coastal flooding in Latin American and the Caribbean (LAC) while accounting for the variations of these factors with location and time. The study assesses the populations, the land areas and the built capital exposed at present and at the middle and end of the 21st century for a set of scenarios that include...
