BACKGROUND Short-term impacts of high temperatures on the elderly are well known. Even though Italy has the highest proportion of elderly citizens in Europe, there is a lack of information on spatial heat-related elderly risks. OBJECTIVES Development of high-resolution, heat-related urban risk maps regarding the elderly population (≥ 65). METHODS A long time-series (2001-2013) of remote sen...
The increased interest in Integrated Assessment (IA) of agricultural systems reflects the growing complexity of policy objectives and corresponding impacts related to this sector. The paper contemplates on the status of quantitative tools for IA in agriculture, drawing on recent European experiences from the development and application of large-scale integrated modelling systems which are both ...
To compare the adoption of healthy lifestyle behaviors, including: spiritual growth, nutrition, physical activity, interpersonal relations, health responsibility, and stress management, of healthcare workers with workers of other professions. Cross-sectional observational study among a convenience sample of 285 healthcare workers and 137 of other professions. The Health-Promoting Lifestyle Prof...
A complete and accurate analysis of the complex spatial structure of heterogeneous hydrocarbon reservoirs requires detailed geological models, i.e. fine resolution models. Due to the high computational cost of simulating such models, single resolution up-scaling techniques are commonly used to reduce the volume of the simulated models at the expense of losing the precision. Several multi-scale ...
the morphological river evolution at long-time (centuries and even millennia) and large spatial scale (watersheds of several square kilometres) can be described by means of simplified 1d models, able to simulate the variation of bed elevation and grain size composition at non-detailed scales, involving a reduced computational effort. the erosion and deposition phenomena acting along rivers can ...
reservoir models with many grid blocks suffer from long run time; it is hence important to deliberatea method to remedy this drawback. usual upscaling methods are proved to fail to reproduce fine gridmodel behaviors in coarse grid models in well proximity. this is attributed to rapid pressure changesin the near-well region. standard permeability upscaling methods are limited to systems with lin...
In this paper, it is assumed that the “Decision Making Units“( ) are consist of positive and negative input and output. Firstly, the optimistic and pessimistic models have been suggested by using negative data and then units with most productive scale size are measured in optimistic and pessimistic models. These productive values are compared with double frontiers and Hurwicz’s Criterion to obt...
in this study, optimized adaptive neuro-fuzzy inference system (oanfis) was employed on a set of daily, weekly, 10-days and monthly data of inflow water into the alavian dam to predict the real-time inflow of the reservoir. sequential and exhaustive search algorithms were used to determine the numbers and time steps of the model inputs and also reducing the prediction’s errors. in sequential se...
with the growth in customers’ demand diversification, mixed-model u-lines (mmul) have acquired increasing importance in the area of assembly systems. there are generally two different approaches in the literature for balancing such systems. some researchers believe that since the types of models can be very diverse, a balancing approach without simultaneously sequencing of models will not yield...
