A Novel Approach for Data Cleaning by Selecting the Optimal Data to Fill the Missing Values for Maintaining Reliable Data Warehouse

At present trillion of bytes of information is being created by projects particularly in web. To accomplish the best choice for business benefits, access to that information in a very much arranged and intuitive way is dependably a fantasy of business administrators and chiefs. Information warehouse is the main feasible arrangement that can bring the fantasy into reality. The upgrade of future attempts to settle on choices relies on upon the accessibility of right data that depends on nature of information basic. The quality information must be created by cleaning information preceding stacking into information distribution center following the information gathered from diverse sources will be grimy. Once the information have been pre-prepared and purified then it produces exact results on applying the information mining question. There are numerous cases where the data is sparse in nature. To get accurate results with sparse data is hard. In this paper the main goal is to fill the missing values in acquired data which is sparse in nature. Precisely caution must be taken to choose minimum number of text pieces to fill the holes for which we have used Jaccard Dissimilarity function for clustering the data which is frequent in nature.
Semiotic Analysis of Persuasive Strategies in Advertising Targeted For Children

This study was designed to analyze the persuasion strategies used in the advertising targeted for children from a semiotic perspective. To persuade a consumer to buy a product, an advertiser must produce persuasive messages. Semiotic approach to the analysis of advertising text lets us to classify advertising signs and sign systems in relation to the way they are transmitted and communicated. This study investigates selective advertisements with the following questions: What types of expression techniques and what types of persuasive appeals are employed. And what are the persuasive premises underlying those persuasive appeals? To do that, Fifty out of 100 printed advertising were selected with the purposive and judgment sampling method. The study results reveal 11 most frequently employed expressive techniques and 9 major types of persuasive appeals and their premises governing the signs and signification systems in the advertising targeted for children. These Ads are as references to authentic material in the ELT literature, material designed for native speakers of English used in the classroom in a way similar to the one it was designed for, so we use advertisements to work on children"s English and communication skills.
A glacial systems model configured for large ensemble analysis of Antarctic deglaciation

Abstract. This article describes the Memorial University of Newfoundland/Penn State University (MUN/PSU) glacial systems model (GSM) that has been developed specifically for large-ensemble data-constrained analysis of past Antarctic Ice Sheet evolution. Our approach emphasizes the introduction of a large set of model parameters to explicitly account for the uncertainties inherent in the modelling of such a complex system. At the core of the GSM is a 3-D thermo-mechanically coupled ice sheet model that solves both the shallow ice and shallow shelf approximations. This enables the different stress regimes of ice sheet, ice shelves, and ice streams to be represented. The grounding line is modelled through an analytical sub-grid flux parameterization. To this dynamical core the following have been added: a heavily parameterized basal drag component; a visco-elastic isostatic adjustment solver; a diverse set of climate forcings (to remove any reliance on any single method); tidewater and ice shelf calving functionality; and a new physically motivated, empirically-derived sub-ice-shelf melt (SSM) component. To assess the accuracy of the latter, we compare predicted SSM values against a compilation of published observations. Within parametric and observational uncertainties, computed SSM for the present-day ice sheet is in accord with observations for all but the Filchner ice shelf. The GSM has 31 ensemble parameters that are varied to account (in part) for the uncertainty in the ice physics, the climate forcing, and the ice–ocean interaction. We document the parameters and parametric sensitivity of the model to motivate the choice of ensemble parameters in a quest to approximately bound reality (within the limits of 31 parameters).
Facies development of the Upper Triassic succession on Barentsøya, Wilhelmøya and NE Spitsbergen, Svalbard

Field data collected from the northeasternmost Triassic exposures on the islands of Spitsbergen, Wilhelmøya and Barentsøya during 2015 are used for sedimentological facies analysis to improve our understanding of the stratigraphic development of the Upper Triassic strata. Results presented here build upon previous studies from the eastern areas of the Svalbard archipelago and seek to extend this understanding northward. Paralic deltaic sediments are recognised throughout the field area, and our analysis shows that the Upper Triassic De Geerdalen Formation is composed of three discrete units defined by the differences in gross depositional environments. The lower interval of early Carnian age is dominated by shallow-marine and delta-front/ shoreface deposits, the middle interval of mid Carnian age is dominated by delta-front to delta-top deposits, and the upper interval, corresponding to the Isfjorden Member, of a late Carnian to early Norian age, is dominated by delta-top deposits which include lagoonal and lacustrine deposits. These observations show that the De Geerdalen Formation represents a more distal depositional setting, than the depositional environments previously reported from the islands of Edgeøya and Hopen. We also document the presence of the Tschermakfjellet Formation and Isfjorden Member on Wilhelmøya, thus increasing our understanding of the northwestward development of the Upper Triassic succession in Svalbard.

The Effects of Giving and Receiving Marginal L1 Glosses on L2 Vocabulary Learning by Upper Secondary Learners.

This paper reports the findings of a study that investigated the effect of giving and receiving marginal L1 glosses on L2 vocabulary learning. To that end, forty nine Iranian learners of English were assigned to three different experimental conditions including marginal L1 glosses Giver (n = 17), marginal L1 glosses Receiver (n = 17), and no glosses Control group (n = 15) with a pretest, immediate, and delayed posttests design. The scores obtained from the fill-in-the-blank and translation test confirmed the homogeneity of the three participating groups in the pretest. During three treatment sessions, participants in the giver group were required to perform the three reading comprehension tasks and consult the bilingual dictionary to look up the targeted lexical items, which were highlighted, and write down their L1 equivalents in the spaces given. The participants in the receiver group were asked to carry out the same reading comprehension tasks which included L1 equivalents of the targeted words. The participants in no marginal glosses group took the same procedure while they had no access to marginal glosses. Two days and four weeks after treatment sessions, all participants took the posttests using the same testing package applied in the pretest. Results of one-way ANOVAs revealed that both the giver and receiver group had an influence on L2 vocabulary learning, the giver group made the most favorable progress over time.
The projected 21st century forest-fire risk in Finland under different greenhouse gas scenarios

We evaluated forest fire potential at four locations in Finland in the current climate and in projected future climates under the B1, A1B and A2 greenhouse-gas (GHG) emission scenarios. In evaluating the forest fire danger potential, the Canadian fire weather index (FWI) system was used. Using the results of the earlier experimental ignition studies, we further estimated the number of fire danger days in different forest stands typical to the northern boreal zone. By the end of the current century, the annual median number of days with elevated forest fire risk is projected to increase by 10%–40%, depending on the GHG scenario. In different forest stands, approximately 5–10 additional fire risk days were found annually based on the A1B and A2 scenarios. Substantially smaller changes are projected under the low-emission B1 scenario. However, there is great inter-annual variability in the forest fire potential which, in the nearest future, largely overwhelms the projected change.
Effects of Picroside II on Myocardial Ischemia-Reperfusion Injury in Streptozotocin-Induced Diabetic Rats

Objective: Diabates mellitus, is a chronic metabolic disorder accompanied by an increase in oxidative stress. Ischemia-reperfusion injury is a cascade of events initiated by tissue ischemia. The cellular damage produced by reperfusion leads to an active inﬂammatory response. This study was performed to investigate the effect of picroside II on myocardial ischemia-reperfusion injury in rats with streptozotocin-induced diabetes. Methods: Animals were equally (n:6) divided for five groups as follows; Control (C), diabetes [D], diabetes+picroside II [DP], diabetes+I/R [DIR], and diabetes+I/R+ picroside II [DIRP]. In DIR group, a left anterior descending artery branch was occluded for 60 minutes, the reperfused for 120 minutes. In DIRP group, picroside II was administrated via 10 mg/kg intraperitoneal route 30 minutes before ligating the left anterior descending artery. At the end of the study, myocardial tissues were taken for total oxidant status and total antioxidant status level determinations. Results: Total oxidant status levels were significantly higher in DIR group, when compared with C, DP, and DIRP groups (p:0.001, p:0.019, and p:0.031, respectively). Total antioxidant status levels were significantly higher in DIR group, when compared with C, DP, and DIRP groups (p:0.006, p:0.024, and p:0.007, respectively). Conclusion: These results indicate that administration of picroside II may have protective effects against I/R injury.

ISO 9001 quality management systems are very popular in Poland. The changes in the standard introduced in 2015 related to, among other things, the treatment of risk management as a vital part of corporate governance, will make companies improve the management of their systems in this respect. The aim of the article is to present a model of organization improvement which takes into account the requirements associated with risk included in the standard ISO 9001: 2015, supported by the guidelines for risk management in accordance with ISO 31000: 2012. The model is the result of compilation work based on the cooperation of the authors of the article with more than 20 industrial enterprises over the past three years.
The Role of Toll−Like Receptors in Pathogenesis of Periodontitis

Toll−like receptors (TLRs) as receptors of innate immunity play a crucial role in sustaining the balance between the immune system of the host and microorganisms. They recognize pathogen associated molecular patterns (PAMPs) and activate a range of mechanisms within a cell which aim at defending the cell against bacteria by producing pro− inflammatory cytokines. When their functioning is impaired by genetic polymorphisms the susceptibility of the organism to infections is changed. Due to the significance of TLRs for microbiota−host factors interactions, TLRs are an object of great interest in the study related to the etiopathogenesis of periodontitis. The aim of this paper is to survey the contemporary literature on various TLRs and the importance of their polymorphisms for the onset and progression of periodontitis. Despite numerous studies, the complexity of processes triggered by TLRs stimu− lation still has not been fully explained and the findings of many studies of their importance in the etiopathogene− sis of periodontitis are contradictory. Therefore it seems worthwhile to conduct further research into the expression and polymorphisms of TLRs (in particular TLR 2 and TLR 4) in order to determine the risk of developing chronic and aggressive periodontitis. This in turn may help to discover the prognosticating factor of both types of perio− dontitis (Dent. Med. Probl. 2009, 46, 1, 94–103).
Post-election audits : statistical power based methods and a trigger for further auditing

Two important components of an audit procedure are the sample size and the decision rule for expanding the audit. This paper describes a method for determining the audit size that ensures a high probability of detecting miscounts if election altering ones exist. Then, two possible triggers for further auditing are developed: a modified bootstrap confidence interval and a modified Hoeffding bound. Both estimate the net gain in votes for the originally reported loser if a full audit were conducted. In simulations, both methods maintained high power for various miscount situations, with the Hoeffding bound having slightly lower false positive rates.
Asociación Argentina de Economía Política Universidad Nacional de Salta, Noviembre de 2006 Structural Change, Success and Crisis in Argentina: Mistaking Transitory for Permanent Export Response

The Argentine crisis of 2001 is examined, under the hypothesis that debt went beyond vulnerability limits because rising exports were perceived as providing permanent enhanced ability to borrow externally; in a prevalent optimistic mood a permanent negative shock in export prices in 1996 was mistakenly taken as purely transitory and further CA deficits deteriorated solvency. This paper provides analytical expression of this argument and explores simulated short run responses of the CA and cumulative debt dynamics. We parameterise a dynamic stochastic general equilibrium model resembling a SOE, simulate both permanent and transitory duration of external shocks, and a magnitude of debt overexpansion is computed. A policy implication is that the difficulty to distinguish trends from transitory disturbances indicate that vulnerable countries like Argentina need to be cautious in the use of external savings, particularly in processes of structural changes when forecasting is more difficult and risky.
HYDRODYNAMICS FOR INELASTIC MAXWELL MIXTURES : SOME APPLICATIONS BY VICENTE GARZÓ AND JOSÉ

Hydrodynamic equations for a binary mixture of inelastic Maxwell models described by the Boltzmann equation are derived. The Navier-Stokes transport coefficients are exactly obtained by solving the Boltzmann equation from the ChapmanEnskog method for states close to the (local) homogeneous cooling state (HCS). The knowledge of the transport coefficients allows one to analyze two different problems. First, we solve the linearized hydrodynamic equations around the homogeneous (cooling) state and identify the conditions for stability as functions of the wave vector, the dissipation, and the parameters of the mixture. As happens for monocomponent systems, the analysis shows that the HCS is unstable to long enough wavelength perturbation. As a second problem, we explore the validity of Onsager’s reciprocal relations of a granular binary mixture. As expected, since a granular system is not time reversal invariant, Onsager’s reciprocal relations do not apply for inelastic collisions. The results show that the absence of the Gibbs state (non-Maxwellian behavior of the velocity distribution functions describing the HCS), the collisional cooling, and the occurrence of different kinetic temperatures for both species (breakdown of energy equipartition) are responsible for a violation of Onsager’s relations.

The Effect of Plating Current Densities on Self-Annealing Behaviors of Electroplated Copper Films

In this study, the effect of plating current densities on self-annealing behaviors of electroplated Cu films was found to be relevant to the polarization resistance of electroplating systems. Porous films with defects occurred at low plating current density or at low polarization resistance. In contrast, dense films with small grains occurred at higher plating current density or at higher polarization resistance. However, when more current was further supplied, Cu aggregation occurred and deposited films became spongy or dendritic. We suggest that both the defects within porous films and the underlying energy of fine-grained deposits accelerated self-annealing. These two characteristics competed with each other to determine the resistivity drop by self-annealing. On the other hand, the (111) texture evolutions of deposited Cu films with an increase of plating current densities were consistent with the evolutions of resistivity and surface morphology. © 2002 The Electrochemical Society.

Chained Gallager codes

The ensemble of regular Low-Density Parity-Check (LDPC) codes introduced by Gallager is considered. Using probabilistic arguments a lower bound on the normalized minimum distance is derived. A new code construction, called Chained Gallager codes, is introduced as the combination of two Gallager codes and its error correcting capabilities are studied.
Low-Cost Printed Flexible Antenna by Using an Office Printer for Conformal Applications

A low-cost inkjet printing method for antenna fabrication on a polyethylene terephthalate (PET) substrate is presented in this paper. An office inkjet printer is used to have desired patterns of silver nanoparticle ink on the PET substrate without any postprocessing. Silver nanoparticle ink cures instantly as soon as it is ejected from the printer on a chemically treated PET substrate. The thickness of the silver nanoparticle layer was measured to be 300 nm with a sheet resistance of as low as 0.3 Ω/sq and a conductivity around 1.11 × 107 S/m with single layer deposition. A coplanar waveguide- (CPW-) fed Z-shape planar antenna on the PET substrate achieved the measured radiation efficiency of 62% and the IEEE gain of 1.44 dBi at 2.45 GHz. The printed antenna is also tested in bending conditions to ascertain its performance for the Internet of things (IoT) conformal applications for the future 5G network.
Nkx2.2 expression in corneal epithelia during pre- and post-natal mice and human development

The Nkx homeodomain proteins play a role in cell type specification and/or maintenance of the differentiated phenotype. To investigate its expression, BAB/C mice were set up for timed mating. All specimens were cryosectioned, the TKE2 cell in two different media were collected for immunohistochemical staining and the cornea from all the time-points of postnatal mice were used for western blotting. We found that NKX2.2 was absent in embryonic stage and began to increase from P15. The expression is similar to that in human cornea epithelia and weak in limbus but strong in adult stage. Our study demonstrates that NKX2.2 expression is developmentally regulated in cornea epithelial cells, and regulated in the differentiation of cornea epithelial cells.
Single coupled-inductor dual output soft-switching DC–DC converters with improved cross-regulation and reduced components

Single inductor dual-output (SIDO) DC-DC converters are attractive in diverse applications such as renewable energy systems and electric vehicles, due to its favourable advantages of reduced magnetic core and high-power density. However, in conventional SIDO converters, severe cross-regulation problem is caused by the multiplex of inductor current, resulting in deteriorated dynamic performance. To alleviate the cross-regulation problem, a new family of dual-output DC-DC converters is proposed in this paper, which employs a coupled inductor to substitute the inductor in SIDO converters. The proposed converters can achieve improved dynamic performance while keeping the advantage of reduced magnetic core. Moreover, the number of semiconductor devices is also reduced in comparison with conventional SIDO converters, and soft-switching operation of switches is also achieved. Therefore, lower cost and higher power density are obtained. Topology derivation of proposed converters from conventional SIDO converters is firstly demonstrated in detail. After that, the operation principle, steady-state characteristics and small-signal model are provided. Finally, design example and experiment results are given to validate the merits of the proposed topology.
Is Urgent Evoke a Digital Ba?: How a Game Can Make Space for Knowledge Creation

Web 2.0 brought a participatory potential with it, prompting organisations to ask themselves how to design social media platforms that can engage external stakeholders in the organisation’s process of knowledge creation and innovation. This chapter presents an analysis of the data from a case study of such a platform, the World Bank’s online game Urgent Evoke, which has been designed with the purpose of engaging citizens in developing innovative solutions for sociopolitical problems like poverty. The analysis is based on Nonaka’s concept of Ba, which means “place” and is described as a platform for advancing the creation of knowledge. The analysis suggests that, in order to create a digital Ba, the design should not only facilitate the four characteristics of Ba that Nonaka has described –socialization, externalization, combination, and internalization. The design should also allow multiple forms of participation, as well as recognise external stakeholders’ contributions to the process of knowledge creation and innovation.
A study of optical observing techniques for extra-galactic supernova remnants: Case of ngc300

We present the results of a study of observational and identification techniques used for surveys and spectroscopy of candidate supernova remnants (SNRs) in the Sculptor Group galaxy NGC300. The goal of this study was to investigate the reliability of using [Sii]:Hα ≥ 0.4 in optical SNR surveys and spectra as an identifying feature of extra-galactic SNRs (egSNRs), and also to investigate the effectiveness of the observing techniques (which are hampered by seeing conditions and telescope pointing errors) using this criterion in egSNR surveys and spectrographs. This study is based on original observations of these objects and archival data obtained from the Hubble Space Telescope which contained images of some of the candidate SNRs in NGC300. We found that the reliability of spectral techniques may be questionable and very high-resolution images may be needed to confirm a valid identification of some egSNRs.
