Ambient air pollution from ground-level ozone and fine particulate matter (PM2.5) is associated with premature mortality. Future concentrations of these air pollutants will be driven by natural and anthropogenic emissions and by climate change. Using anthropogenic and biomass burning emissions projected in the four Representative Concentration Pathway scenarios (RCPs), the ACCMIP ensemble of ch...
Temperature rise is a concern for future agriculture in different regions of the globe. This study aimed to reveal changes and variabilities minimum temperature (Tmin) maximum (Tmax) monthly, seasonal, annual scale over Bangladesh using 40 General Circulation Models (GCMs) Coupled Model Intercomparison Project Phase 5 (CMIP5) two radiative concentration pathways (RCPs, RCP4.5 RCP8.5). The stati...
Resource-constrained project scheduling (RCPS) is often a challenging issue in practice, due to its combinatorial nature and uncertainty. This paper presents the framework of a heuristic approach to fuzzy RCPS problems using a fuzzy parallel scheduling method. This approach can handle both fuzzy and crisp numbers which commonly coexist in many realistic RCPS problems. Key-Words: Resource-constr...
In this paper we present a destructive lower bound for a number of resource constrained project scheduling (RCPS) problems, which is based on column generation. We first look at the problem with only one resource. We show how to adapt the procedure by Van den Akker et al. [1] for the problem of minimizing maximum lateness on a set of identical, parallel machines such that it can be used to solv...
Globally, the impacts of anthropogenic climate change can displace species into more favourable climates. Semi-arid desert specialists, such as sandhill dunnart, Sminthopsis psammophila, are typically susceptible to rainfall deficits, wildfires and extreme temperatures caused by change. We first used maximum entropy (MaxEnt) distribution models (SDMs) predict current S. psammophila. Between 201...
Climate change has resulted in serious social-economic ramifications and extremely catastrophic weather events the world, Tanzania Zanzibar particular, with adaptation being only option to reduce impacts. The study focuses on influence of climate variability spatio-temporal rainfall temperature distribution Zanzibar. station observation datasets rainfall, Tmax Tmin acquired from Meteorological ...
