—Homomorphic message authentication codes (MAC) have been proposed to thwart pollution attacks in network coding. The existing schemes mainly are based on the vector inner product or trace function over finite fields. Recently, Wang and Hu presented a generic construction of homomorphic MAC scheme based on linear mapping over finite fields which is an excellent abstract of the vector inner pro...

today the environmental consequences and earth resources unresponsiveness is transformed to the main concern of human. at the same time increasing environmental pollution and its devastating consequences following that, increased consumer and environmental demand for sustainable products and services must try to reduce pollution caused by industrial development in the form of efforts to impleme...

abstractbackground and objectives: considering progressive growth of industry and technology, the accumulation of environmental contaminants, especially heavy metals (hms) in the soil is of increasing worldwide concern about the probable soil pollution risks. the perception of pollutants spatial distribution pattern and recognition of factors which control this pattern and identification of pro...

Air pollution primarily originates from substances that are directly emitted natural or anthropogenic processes, such as carbon monoxide (CO) gas in vehicle exhaust sulfur dioxide (SO2) released factories. However, a major air problem is particulate matter (PM), which an adverse effect of wildfires and open burning. Application tools for monitoring risk areas using real-time with drones have em...

Four different methods of epiphytic lichen mapping were used for the assessment of air quality in the region under the influence of the Sostanj Thermal Power Plant (Salek Valley, Slovenia). Three methods were based on the presence of different lichen species (VDI, EU and ICP-Forest), the fourth on a frequency and coverage assessment of different growth forms of epiphytic lichens, e.g. crustose,...

a methodology of ecological risk assessment for the terrestrial ecosystem under chronicradioactive pollution of a biotope near a regional radioactive waste storage has been developed in terms of thecritical environmental loads analyzed. it consists of five stages: determination of effect indicators and assessmentof their values; establishment of reference species and indices; assessment and ana...

OBJECTIVES A relationship between ambient air pollution and adverse birth outcomes has been found in a large number of studies that have mainly used a nearest monitor methodology. Recent research has suggested that the effect size may have been underestimated in these studies. This paper examines associations between birth outcomes and ambient levels of residential and workplace sulphur dioxide...
