GIS-Based Accident Location and Analysis System (GIS-ALAS) Project Report: Phase 1, 1998

This report summarizes progress made in Phase 1 of the GIS-based Accident Location and Analysis System (GIS-ALAS) project. The GIS-ALAS project builds on several longstanding efforts by the Iowa Department of Transportation (DOT), law enforcement agencies, Iowa State University, and several other entities to create a locationally-referenced highway accident database for Iowa. Most notable of these efforts is the Iowa DOT’s development of a PC-based accident location and analysis system (PC-ALAS), a system that has been well received by users since it was introduced in 1989. With its pull-down menu structure, PC-ALAS is more portable and user-friendly than its mainframe predecessor. Users can obtain accident statistics for locations during specified time periods. Searches may be refined to identify accidents of specific types or involving drivers with certain characteristics. Output can be viewed on a computer screen, sent to a file, or printed using pre-defined formats.

Sooty blotch and flyspeck control with fungicide applications based on calendar, local IPM, and warning system

The objective of this work was to compare fungicide application timing for the control of sooty blotch and flyspeck (SBFS) of 'Fuji' apples in Rio Grande do Sul state, Brazil. The following treatments were evaluated in two growing seasons: two warning system-based (modified version of the Brown-Sutton-Hartmann system) spray of captan plus thiophanate methyl, with or without summer pruning; two calendar/rain-based spray of captan or a mixture of captan plus thiophanate methyl; fungicide spray timing based on a local integrated pest management (IPM) for the control of summer diseases; and a check without spraying. Sooty blotch and flyspeck incidence over time and their severity at harvest were evaluated. The highest number of spray was required by calendar/rain-based treatments (eight and seven sprays in the sequential years). The warning system recommended five and three sprays, in the sequential years, which led to the highest SBFS control efficacy expressed by the reduced initial inoculum and disease progress rate. Summer pruning enhanced SBFS control efficacy, especially by suppressing SBFS signs which tended to be restrained to the peduncle region of the fruit. Sooty blotch and flyspeck can be managed both with calendar and the grower-based IPM practices in Brazil, but a reduced number of sprays is required when the warning system is used.

The planarian flatworm: an in vivo model for stem cell biology and nervous system regeneration

Planarian flatworms are an exception among bilaterians in that they possess a large pool of adult stem cells that enables them to promptly regenerate any part of their body, including the brain. Although known for two centuries for their remarkable regenerative capabilities, planarians have only recently emerged as an attractive model for studying regeneration and stem cell biology. This revival is due in part to the availability of a sequenced genome and the development of new technologies, such as RNA interference and next-generation sequencing, which facilitate studies of planarian regeneration at the molecular level. Here, we highlight why planarians are an exciting tool in the study of regeneration and its underlying stem cell biology in vivo, and discuss the potential promises and current limitations of this model organism for stem cell research and regenerative medicine.

Improving ERP change tool processes to align business processes and ERP system

Nopea teknologian kehitys sekä kansainvälistymisen mukana tuoma kilpailupaine pakottavat yritykset jatkuvaan liiketoimintaprosessien kehittämiseen. Muutoksista organisaation rakenteissa sekä yrityksen prosesseissa on tullut yleisiä toimenpiteitä. Yksi näkyvimmistä toiminnallisista uudistuksesta on ollut toiminnanohjausjärjestelmän käyttöönotto. Toiminnanohjausjärjestelmän rakenne ja kehitys aiheuttaa yleensä suurimmat vaikeudet pyrittäessä rakentamaan liiketoimintaprosessien läpinäkyvyyttä esittävä tietojärjestelmäympäristö. Tässä tutkimuksessa liiketoiminnan sekä toiminnanohjausjärjestelmän prosessien yhdistäminen on tehty ns. toiminnanohjausjärjestelmä muutostyökaluilla. Kyseiset muutostyökalut on järjestetty yrityksissä tietojärjestelmä ympäristöön ja niiden avulla voidaan korjata teknisiä ongelmia sekä muuttaa itse prosesseja. Tutkimuksen empiria osuudessa on käytetty case-tutkimusmenetelmää Kone Oyj:n prosessien kehittämisosastolla. Tutkimuksen tavoitteena oli parantaa toiminnanohjausjärjestelmän muutostyökalujen prosesseja, liiketoimintaprosessien sekä toiminnanohjausjärjestelmän yhdistämiseksi ja harmonisoimiseksi. Tutkimuksen tavoitteiden täyttämiseksi, prosessijohtamisen käsitteitä käytettiin muutostyökaluprosessien parannusehdotusten löytymiseksi. Prosessijohtamisen käsitteet tarkoittavat prosessikartan, prosessin toimintojen, sekä prosessin kustannusten tutkimista ja hyväksikäyttöä. Prosessijohtamisen käsitteeseen kuuluu myös liiketoimintaprosessien jatkuvan parantamisen sekä uudelleenjärjestämisen mallien kuvaus. Toiminnanohjausjärjestelmäympäristön kuvaus teorian toisena osuutena antaa pohjaa muutostyökalujen prosessien käytölle. Tutkimuksen tuloksina voidaan todeta että tutkimusalue on hyvin monimutkainen ja vaikea. Toimintajärjestelmistä ei ole kirjoitettu teoriaa kovinkaan runsaasti, lukuunottamatta yritysten itse tekemiä tutkimuksia. Tutkimuksessa tarkasteltaville prosesseille löytyi kuitenkin parannusehdotuksia sekä ns. optimaalisen prosessimallin ominaisuuksia.

Improving algorithm speed in PNL mixture separation and Wiener system inversion

This paper proposes a very simple method for increasing the algorithm speed for separating sources from PNL mixtures or invertingWiener systems. The method is based on a pertinent initialization of the inverse system, whose computational cost is very low. The nonlinear part is roughly approximated by pushing the observations to be Gaussian; this method provides a surprisingly good approximation even when the basic assumption is not fully satisfied. The linear part is initialized so that outputs are decorrelated. Experiments shows the impressive speed improvement.

Breast imaging reporting and data system (BI-RADS™): como tem sido utilizado?

O Breast Imaging Reporting and Data System (BI-RADS™), do American College of hRadiology, foi concebido para padronizar o laudo mamográfico e reduzir os fatores de confusão na descrição e interpretação das imagens, além de facilitar o monitoramento do resultado final. OBJETIVO: Identificar a maneira como vem sendo utilizado o BI-RADS™, gerando informações que possam auxiliar o Colégio Brasileiro de Radiologia a desenvolver estratégias para aperfeiçoar o seu uso. MATERIAIS E MÉTODOS: Os dados foram coletados na cidade de Goiânia, GO. Foram solicitados os exames de mamografia anteriores a todas as mulheres que se dirigiram ao serviço para realização de mamografia entre janeiro/2003 e junho/2003. Foram incluídos na análise exames anteriores, realizados entre 1/7/2001 e 30/6/2003. RESULTADOS: Foram coletados 104 laudos anteriores, emitidos por 40 radiologistas de 33 diferentes serviços. Dos 104 laudos, 77% (n = 80) utilizavam o BI-RADS™. Destes, apenas 15% (n = 12) eram concisos, nenhum utilizava a estrutura e organização recomendadas pelo sistema, 98,75% (n = 79) não respeitavam o léxico e 65% (n = 51) não faziam recomendação de conduta. CONCLUSÃO: O BI-RADS™, apesar de bastante utilizado, não foi reconhecido como sistema para padronização dos laudos. Foi usado quase exclusivamente como forma de classificação final dos exames.

Modernization of protection and control system of HV/MV substation in Russia

This work describes different possibilities of protection and control system improvement of primary distribution substation. The status of condition and main problems of power networks from reliability point of view in Russia are described. This work studies technologies used today in Russia for protection of distribution networks with their disadvantages. Majority of medium voltage networks (6-35 kV) has isolated network point. There is still no any protection available on the market which allows to estimate distance to fault in case of earth fault. The thesis analyses methods of earth fault distance calculation. On the basis of computer simulation the influence of various factors on calculation accuracy is studied. The practical implementation of the method presupposes usage of digital relay. Application of digital relay is accompanied by numerous opportunities which are described in this work. Also advantages of system implemented on the basis of IEC 61850 standard are examined. Finally, suitability of modern digital relays from GOST standard point of view is analyzed.
