! . p Figure 1: Calculation of Concentration Index Abstract: Concentration index filter is a kind of spatial filters of images, and its typical application is diagnosis from medical images. This paper presents a dedicated computing engine for concentration index filtering. Original algorithm is modified to extract full parallelism and data width is optimized for maximizing clock speed and minim...

this study aimed to develop an index that can rank welding workplace that associate well with possible health risk of welders.welding fumes health index (wfhi) were developed based on data from case studies conducted in plant 1 and plant 2. personal sampling of welding fumes to assess the concentration of metal constituents along with series of lung function tests was conducted. fifteen metal c...

The present study attempted deriving and solving the falling- cylinder governing equations for power law model non-Newtonian fluids. Based on this theoretical study, a novel falling- cylinder rheometer (FCR) was designed and constructed to measure the Theological properties of non-Newtonian fluids. Different falling cylinders with predesigned densities were used to determine the apparent viscos...

We propose a new local feature called three dimensional(3D) concentration index for analyzing line texture patterns in the 3D space. This feature can be used for evaluating quantitatively local concentration of lines at each point of a 3D line pattern. In the paper, simulations using arti cial patterns is performed to examine basic properties of the index. The index is also applied to patterns ...

Abstract Variations in rainfall characteristics play a key role available water resources for country. In this study, spatial and temporal variations Iran were determined using the daily concentration index (DRCI) monthly percentage (MRPI), based on 30-year (1987–2016) precipitation records from 80 meteorological stations throughout Iran. The results showed that MRPI differed between locations ...

In contrast with Mobility Factor (MF) and Risk Assessment Code (RAC) indices, IR attributes a risk share to metal species bound to reducible and oxidizable phases which are totally neglected in both of the two above-mentioned indices. In other words, besides the absolutely mobile fractions, the potentially mobile ones are also regarded in risk evaluation process elaborated by IR. The different ...

Mindfulness is defined as paying attention in the present moment. We investigate the hypothesis that mindfulness training may alter or enhance specific aspects of attention. We examined three functionally and neuroanatomically distinct but overlapping attentional subsystems: alerting, orienting, and conflict monitoring. Functioning of each subsystem was indexed by performance on the Attention N...

Attention is critical for successful performance in demanding real-world situations. Yet, protracted periods of high demand may compromise attention and increase offtask thinking. Herein, we investigate if mindfulness training (MT) may promote cognitive resilience by curbing attentional lapses in high-stress cohorts. Two military cohorts were recruited during their high-stress predeployment int...

Therapeutic drug monitoring is aimed at using drug concentration measurements to manage a patient's medication requirement and optimise clinical outcome, particularly in respect of drugs with narrow therapeutic index. Typically, immunoassay methods of various techniques are employed with the advantage of rapid turnaround time and ease of operation. The chromatographic methods are specific and c...

BACKGROUND To measure socioeconomic inequalities in maternal health services in rural western China and to analyze the determinants' contributions of inequalities. STUDY DESIGN a cross-sectional study. METHODS The data utilized in this study were obtained from a cross-sectional study from 10 provinces in rural Western China in 2005. Wealth index of household socioeconomic status was develop...
