ІНФОРМАЦІЙНІ ТЕХНОЛОГІЇ ПРОСТОРОВОЇ ІНВЕНТАРИЗАЦІЇ ПАРНИКОВИХ ГАЗІВ У ЕНЕРГЕТИЧНОМУ СЕКТОРІ СІЛЕЗЬКОГО ВОЄВОДСТВА

GIS technology of spatial inventory of greenhouse gases (carbon dioxide, methane, etc.) in the energy sector of Silesia Region in Poland has been presented. Georeferenced databases, GIS software, and international inventory methodologies have been used. The mathematical models for inventory of carbon dioxide, methane and other greenhouse gases during the combustion of fuel in the production of electricity, in the residential sector, industry, construction, and transport have beencreated. These models allow to obtain the spatial distribution of total emissions of greenhouse gases of Silesia Region, taking into account the contribution of each region in the overall processes of emission.Представлено геоінформаційні технології просторової інвентаризації парникових газів (двоокису вуглецю, метану та ін.) в енергетичному секторі в Сілезькому воєводстві Польщі.

Exploratory Analysis of Highly Heterogeneous Document Collections

We present an effective multifaceted system for exploratory analysis of highly heterogeneous document collections. Our system is based on intelligently tagging individual documents in a purely automated fashion and exploiting these tags in a powerful faceted browsing framework. Tagging strategies employed include both unsupervised and supervised approaches based on machine learning and natural language processing. As one of our key tagging strategies, we introduce the KERA algorithm (Keyword Extraction for Reports and Articles). KERA extracts topic-representative terms from individual documents in a purely unsupervised fashion and is revealed to be significantly more effective than state-of-the-art methods. Finally, we evaluate our system in its ability to help users locate documents pertaining to military critical technologies buried deep in a large heterogeneous sea of information.Comment: 9 pages; KDD 2013: 19th ACM SIGKDD Conference on Knowledge Discovery and Data Minin

МОДЕЛЮВАННЯ ЕМІСІЙ ПАРНИКОВИХ ГАЗІВ ВІД СПАЛЮВАННЯ ПРИРОДНОГО ТА СКРАПЛЕНОГО ГАЗУ В ЖИТЛОВОМУ СЕКТОРІ РІВНЕНСЬКОЇ ОБЛАСТІ

Based on the analysis of natural and liquefied gases used in residential sector in Rivne region an approach to inventory and spatial analysis of greenhouse gas emissions caused by burning these fossil fuels is presented. The mathematical model and the algorithms for spatial inventory of greenhouse gases, based on territorial disaggregation of burned fuels, which gives possibility to create georeferenced cadastres of emissions in the residential sector, are developed. Based on performed numerical experiments the digital map and database of greenhouse gas emissions in Rivne region are obtained. Analysis of emission processes is conducted for elementary areas 2 km × 2 km in size.На основі аналізу цільового використання природного та скрапленого газу у житловому секторі Рівненської області представлено загальний підхід до процесу інвентаризації та просторового аналізу емісій парникових газів від спалювання цих видів палива. Розроблено математичну модель та алгоритми дослідження процесів емісії парникових газів у житловому секторі, що ґрунтуються на територіальному розподілі спаленого населенням палива з врахуванням показників густоти населення, питомої житлової площі, обладнаної газом та опаленням, і дають можливість формувати георозподілені кадастри емісій парникових газів. На підставі здійснених числових експериментів отримано цифрову карту та відповідну георозподілену базу даних, які містять інформацію про джерела та кількісні оцінки емісії в розрізі окремих елементарних об’єктів розміром 2 х 2 км

The impact of customer-specific marketing expenses on customer retention and customer profitability

We study the effects of customer-specific marketing expenses on customer retention and customer profitability in a business-to-business setting. Using data from a company providing hygiene services, we look at the impact of a hitherto unstudied type of expense targeted at individual customer relationships: the offering of free equipment to customers. The data allow tracking the activities performed in more than 4,500 customer relationships over a period of 4 years. Retention rates are higher for customers targeted with free equipment, but this effect results from an interaction with customer size. First-order dynamic panel data analyses show that the impact of targeted marketing expenses on customer dollar profit is positive for large customers, but there is no effect for smaller customers. Thus, targeted marketing expenses seem to be a tool for relationship maintenance rather than customer development: they help in retaining large customers that generate more profit, but they do not seem to work in developing new customers into larger, more profitable ones

Strangeness from 20 AGeV to 158 AGeV

New results from the energy scan programme of NA49, in particular kaon production at 30 AGeV and phi production at 40 and 80 AGeV are presented. The K+/pi+ ratio shows a pronounced maximum at 30 AGeV; the kaon slope parameters are constant at SPS energies. Both findings support the scenario of a phase transition at about 30 AGeV beam energy. The phi/pi ratio increases smoothly with beam energy, showing an energy dependence similar to K-/pi-. The measured particle yields can be reproduced by a hadron gas model, with chemical freeze-out parameters on a smooth curve in the T-muB plane. The transverse spectra can be understood as resulting from a rapidly expanding, locally equilibrated source. No evidence for an earlier kinetic decoupling of heavy hyperons is found.Comment: Contribution to the proceedings of "Strangeness in Quark Matter 2003" (March 2003, Atlantic Beach NC, USA), to be published in Journal of Physics G. 11 pages, 14 figure

Lambda production in central Pb+Pb collisions at CERN-SPS energies

In this paper we present recent results from the NA49 experiment for $\Lambda$ and $\bar{\Lambda}$ hyperons produced in central Pb+Pb collisions at 40, 80 and 158 A$\cdot$GeV. Transverse mass spectra and rapidity distributions for $\Lambda$ are shown for all three energies. The shape of the rapidity distribution becomes flatter with increasing beam energy. The multiplicities at mid-rapidity as well as the total yields are studied as a function of collision energy including AGS measurements. The ratio $\Lambda/\pi$ at mid-rapidity and in 4$\pi$ has a maximum around 40 A$\cdot$GeV. In addition, $\bar{\Lambda}$ rapidity distributions have been measured at 40 and 80 A$\cdot$GeV, which allows to study the $\bar{\Lambda}$/$\Lambda$ ratio.Comment: SQM proceedings. J. Phys. G: Nucl.

What should be known prior to performing EUS exams? (Part II)

In "What should be known prior to performing EUS exams, Part I," the authors discussed the need for clinical information and whether other imaging modalities are required before embarking EUS examinations. Herewith, we present part II which addresses some (technical) controversies how EUS is performed and discuss from different points of view providing the relevant evidence as available. (1) Does equipment design influence the complication rate? (2) Should we have a standardized screen orientation? (3) Radial EUS versus longitudinal (linear) EUS. (4) Should we search for incidental findings using EUS
