Big Data Classification Using Distributed Optimized Hoeffding Trees
Authors: Desai Sharmishta Suhas , Patil S. T. 
Published: March 2019

Large usage of social media, online shopping or transactions gives birth to voluminous data. Visual representation and analysis of this large amount of data is one of the major research topics today. As this data is changing over the period of time, we need an approach which will take care of velocity of data as well as volume and variety. In this paper, author has proposed a distributed method which will handle three dimensions of data and gives good results as compared to other method. Traditional algorithms are based on global optima which are basically memory resident programs. Our approach which is based on optimized hoeffding bound uses local optima method and distributed map-reduce architecture. It does not require copying whole data set onto a memory. As the model build is frequently updated on multiple nodes concurrently, it is more suitable for time varying data. Hoeffding bound is basically suitable for real time data stream. We have proposed very efficient distributed map-reduce architecture to implement hoeffding tree efficiently. We have used deep learning at leaf level to optimize the hoeffding tree. Drift detection is taken care by the architecture itself no separate provision is required for this. In this paper, with experimental results it is proved that our method takes less learning time with more accuracy. Also distributed algorithm for hoeffding tree implementation is proposed.
THE CHOICE OF NORMALIZATION METHOD AND RANKINGS OF THE SET OF OBJECTS BASED ON COMPOSITE INDICATOR VALUES
Authors: Walesiak Marek 
Published: March 2019

Abstract
The choice of the normalization method is one of the steps for constructing a composite indicator for metric data (see, e.g. Nardo et al., 2008, pp. 19-21). Normalization methods lead to different rankings of the set of objects based on composite indicator values. In the article 18 normalization methods and 5 aggregation measures (composite indicators) were taken into account. In the first step the groups of normalization methods, leading to identical rankings of the set of objects, were identified. The considerations included in Table 3 reduce this number to 10 normalization methods. Next, the article discusses the procedure which allows separating groups of normalization methods leading to similar rankings of the set of objects separately for each composite indicator formula. The proposal, based on Kendall’s tau correlation coefficient (Kendall, 1955) and cluster analysis, can reduce the problem of choosing the normalization method. Based on the suggested research procedure the simulation results for five composite indicators and ten normalization methods were presented. Moreover, the proposed approach was illustrated by an empirical example. Based on the analysis of the dendrograms three groups of normalization methods were separated. The biggest differences in the results of linear ordering refer to methods n2, n9a against the other normalization methods.
THE COMPARISON OF INCOME DISTRIBUTIONS FOR WOMEN AND MEN IN POLAND USING SEMIPARAMETRIC REWEIGHTING APPROACH
Authors: Urbanczyk Dominika Marta , Landmesser Joanna Małgorzata 
Published: March 2019

Abstract
In this paper, we compare the income distributions for women and men in Poland. The gender wage gap can only be partially explained by different men’s and women’s characteristics. The unexplained part of the gap is usually attributed to the wage discrimination. The objective of the study is to extend the Oaxaca-Blinder decomposition procedure for the pay gap along the whole income distribution. To describe differences between two distributions of incomes we use a semiparametric reweighting approach (DiNardo, Fortin, Lemieux, 1996). The reweighting factor is computed for each observation by estimating a logit model for probabilities of belonging to men’s or women’s group. Then, we estimate probability density functions, including the counterfactual density function, using kernel density methods. This allows us to decompose the inequalities into the explained and unexplained components. The analysis is based on the EU-SILC data for Poland in 2014.
Role of filtration in managing the risk from Cryptosporidium in commercial swimming pools – a review
Authors: Wood Martin , Simmonds Lester , MacAdam Jitka , Hassard Francis , Jarvis Peter , Chalmers Rachel M. 
Published: March 2019

Abstract
Most commercial swimming pools use pressurised filters, typically containing sand media, to remove suspended solids as part of the water treatment process designed to keep water attractive, clean and safe. The accidental release of faecal material by bathers presents a poorly quantified risk to the safety of swimmers using the pool. The water treatment process usually includes a combination of maintaining a residual concentration of an appropriate biocide in the pool together with filtration to physically remove particles, including microbial pathogens, from the water. However, there is uncertainty about the effectiveness of treatment processes in removing all pathogens, and there has been growing concern about the number of reported outbreaks of the gastrointestinal disease cryptosporidiosis, caused by the chlorine-resistant protozoan parasite Cryptosporidium. A number of interacting issues influence the effectiveness of filtration for the removal of Cryptosporidium oocysts from swimming pools. This review explains the mechanisms by which filters remove particles of different sizes (including oocyst-sized particles, typically 4–6 μm), factors that affect the efficiency of particle removal (such as filtration velocity), current recommended management practices, and identifies further work to support the development of a risk-based management approach for the management of waterborne disease outbreaks from swimming pools.

Microbial Storage and Consecutive Waste Constituent Removal by Activated Sludge
Authors: Brodersen K. T. 
Published: March 2019

Abstract
The stabilization of a waste by activated sludge is accomplished in part through a number of complex metabolic pathways consisting of a multitude of biochemical reactions. Knowledge of these pathways has led to the development of pure culture kinetics which sanitary engineers, among others, have applied to heterogeneous populations metabolizing multi-component substrates. Consequently a number of kinetic models have been formulated and used to describe and predict waste removal characteristics by activated sludge. These models assume that all waste constituents are removed simultaneously, and thus consider the waste as a single unit. However, since most wastes consist of a number of components, it seems reasonable to obtain a more accurate kinetic model, the removal of each individual waste constituent should be considered. This would be particularly true if various waste constituents are removed in specific sequences.
Research in Coalescence for the Treatment of Oily Wastes
Authors: Woods Donald R. , Burrill Kenneth A. 
Published: March 2019

Abstract
The separation of dispersed oil from water requires that the dispersed oil drops move to and coalesce at the oil-water interface. Normally the coalescence step of this separational process as applied to waste water treatment is neglected because the time for coalescence to occur is short relative to the migration time. Indeed, in the API design of oil skimmers (API 1963) the coalescence time and the thickness of the oil layer are both neglected. Nevertheless, some conditions when coalescence is important for waste treatment are: 1.in the design and operation of decanters upstream of the waste treatment process. The effectiveness of these dictate the complexity of the waste water treatment.2.in solvent extraction methods for treating stable dispersions of oily waste water. Such a method has been successfully developed to treat the oily waste from rolling mills in steel companies (Woods and Zirimenya (1968 ff) ).3.when concentrated, stable emulsions are the waste.4.when space is at a premium (Woods (1968), Shackleton et al (1960) and Douglas and Elliott (1961)).
Our knowledge of coalescence in liquid-liquid systems is limited and often contradictory. Consider first some background on what we know about coalescence. Then, we describe an experimental technique and recent results on the coalescence of single drops at a planar interface.
A Stochastic Model for Primary Settlers
Authors: Singh D.P. , Bryson A.W. , Silveston P.L. 
Published: March 2019

Abstract
Stochastic models of process units are useful where the flow and concentrations in a feed stream vary appreciably over long time periods in a random way. Models yield not only the mean, but provide a measure of the variation around the mean. Assuming sedimentation can be described by a rate equation, stochastic models are developed for zero, first and second order rate processes. The zero order model can be rejected because it cannot be made to fit plant data, while the second order model was not developed further because of its complexity. The rate parameter for the first order model was evaluated from 1968 suspended solids data for the Kitchener Sewage Treatment Plant and found to have zero variance. Testing the model against 1966 and 1967 data and shorter period for 1968 showed that the model predicted suspended solids and BOD removals differing on the average from plant results by 10%. The first order stochastic model gives, thus, a satisfactory representation of primary settler performance.
Conversion of Industrial Wastes to Produce Useful Bio-Organics
Authors: Peacock F.G. , Page O. T. 
Published: March 2019

Abstract
Studies were conducted on the biological degradation, by the fungus Fusarium moniloforme, of solubles in effluent from food processing plant wastes. Initial pH of the effluent ranged from 10.5 to 11.5. Marked decreases in pH were found to occur during fungal growth. UV spectrophotometric analyses (200–450nm) of this effluent showed a progressive decrease in absorbance over several days of treatment. Starch, a major component of the effluent, was utilized and eliminated by the organism as determined by visual and spectrophotometric IKI tests. Chromatographic analysis before and after treatment indicated a substantial decrease in the number of amino acids whether marketable by-produce were produced by the fungus during this process, examinations of the treated waste are being carried out. IR spectrophotometric determinations of steroids have been made in dry chloroform extracts following controlled fungal growth on primary treated effluent.
Problems in Detoxifying Fresh Waters Polluted by Base Metal Minewaters
Authors: Kresta Vaclav , Ward Gerald B. 
Published: March 2019

Abstract
At many mining sites process (milling) and drainage waters escape treatment and cause receiving waters to become contaminated above avoidance or even toxic levels for fish.
The present know-how on chemical agents which can be used to complex with copper and zinc to form non-toxic compounds is limited to chelating agents such as NTA or EDTA. Preferential reaction with trivalent ions such as iron means that such ions must be tied up before complexation of copper and zinc can occur. As the amount of iron in contaminated water is usually two to eight times higher than that of copper and zinc, high dosages of chelating agents are usually required.
In this project, the use of salts of anthranilic acid, especially calcium anthranilate, was investigated. The consumption of anthranilateions was found to be about the same as that of NTA or EDTA, i.e. four milligrams per milligram of copper or zinc. The total dosage to be applied to contaminated waters would be, however, several times lower as iron is not involved in the reactions and copper and zinc are complexed in that order.
Toxicity tests to compare the efficiency and dasages of calcium anthranilate and NTA or EDTA are presently being carried out.
A Study of Pollutional Loadings from Urban Storm Runoff
Authors: Warnock Richard G. 
Published: March 2019

Abstract
As efforts are made to maintain and improve the water quality in lakes and rivers, the contribution of pollutional loadings from uncontrolled sources becomes more important. A recent study (Whipple, W.J. “BOD Mass Balance and Water Quality Standards”, Water Resources Research, 6 (3), 827, 1970.) of New Jersey rivers presented results that showed that for BOD loadings within selected portions of the rivers the amounts of BOD which could be attributed to controlled sources varied from 7 to 39 percent. With such low percentages subject to control, the economics of improved water quality through advanced waste treatment must be closely examined.
In order to do this, it is necessary to have detailed information on the background pollution from uncontrolled sources. This paper is a report of a study to determine such information. Measurements of various parameters to represent the pollutional loadings were made on the storm runoff from a small urban catchment in Ottawa, Ontario. Significant levels of some of these parameters were noted. Variations in concentration were also determined throughout individual storms. This information is useful in determining the expected load from these sources and in attempting to reduce it.
