USER'S GUIDE FOR ADVANCED PROCESS SIMULATION SOFTWARE APROS 5

Tässä diplomityössä tehtiin käyttäjän opas kehittyneelle prosessisimulointiohjelmistolle APROS 5. Opas on osa VTT Energialle tehtävää APROS 5 käyttäjän koulutuspakettia, joka julkaistaan myöhemmin CD-ROM -muotoisena. Prosessisimulointiohjelmistoa AAPROS 5 voidaan käyttää termohydraulisten prosessien, automaatiopiirien ja sähköjärjestelmien mallinnuksessa. Ohjelma sisältää myös neutroniikkamallin ydinreaktorin käyttäytymisen mallintamiseksi. APROS:in aikaisemmilla UNIX-ympäristössä toimivilla versioilla on toteutettu useita ydinvoimalaitosten turvallisuustutkimukseen liittyviä analyysejä ja sekä ydinvoimalaitosten että konventionaalisten voimalaitosten koulutussimulaattoreita. APROS 5 toimii Windows NT -ympäristössä ja on oleellisesti erilainen käyttää kuin aikaisemmat versiot. Tämän myötä syntyi tarve uudelle käyttäjän oppaalle. Käyttäjän oppaassa esitetään APROS 5:n tärkeimmät toiminnot, mallinnuksen periaatteet ja termohydraulisten ja neutroniikan ratkaisumallit. Lisäksi oppaassa esitetään esimerkki, jossa mallinnetaan yksinkertaistettu VVER-440 -tyyppisen ydinvoimalaitoksen primääripiiri. Yksityiskohtaisempaa tietoa ohjelmistosta on saatavilla APROS 5 -dokumentaatiosta.

Social justice in education : how the function of selection in educational institutions predicts support for (non)egalitarian assessment practices

Educational institutions are considered a keystone for the establishment of a meritocratic society. They supposedly serve two functions: an educational function that promotes learning for all, and a selection function that sorts individuals into different programs, and ultimately social positions, based on individual merit. We study how the function of selection relates to support for assessment practices known to harm vs. benefit lower status students, through the perceived justice principles underlying these practices. We study two assessment practices: normative assessment-focused on ranking and social comparison, known to hinder the success of lower status students-and formative assessment-focused on learning and improvement, known to benefit lower status students. Normative assessment is usually perceived as relying on an equity principle, with rewards being allocated based on merit and should thus appear as positively associated with the function of selection. Formative assessment is usually perceived as relying on corrective justice that aims to ensure equality of outcomes by considering students' needs, which makes it less suitable for the function of selection. A questionnaire measuring these constructs was administered to university students. Results showed that believing that education is intended to select the best students positively predicts support for normative assessment, through increased perception of its reliance on equity, and negatively predicts support for formative assessment, through reduced perception of its ability to establish corrective justice. This study suggests that the belief in the function of selection as inherent to educational institutions can contribute to the reproduction of social inequalities by preventing change from assessment practices known to disadvantage lowerstatus student, namely normative assessment, to more favorable practices, namely formative assessment, and by promoting matching beliefs in justice principles.

Interface Implementation for GPRS/PCU Software Testing with Emulators

Jatkuvasti lisääntyvä matkapuhelinten käyttäjien määrä, internetin kehittyminen yleiseksi tiedon ja viihteen lähteeksi on luonut tarpeen palvelulle liikkuvan työaseman liittämiseksi tietokoneverkkoihin. GPRS on uusi teknologia, joka tarjoaa olemassa olevia matka- puhelinverkkoja (esim. NMT ja GSM) nopeamman, tehokkaamman ja taloudellisemman liitynnän pakettidataverkkoihin, kuten internettiin ja intranetteihin. Tämän työn tavoitteena oli toteuttaa GPRS:n paketinohjausyksikön (Packet Control Unit, PCU) testauksessa tarvittavat viestintäajurit työasemaympristöön. Aidot matkapuhelinverkot ovat liian kalliita, eikä niistä saa tarvittavasti lokitulostuksia, jotta niitä voisi käyttää GPRS:n testauksessa ohjelmiston kehityksen alkuvaihessa. Tämän takia PCU-ohjelmiston testaus suoritetaan joustavammassa ja helpommin hallittavassa ympäristössä, joka ei aseta kovia reaaliaikavaatimuksia. Uusi toimintaympäristö ja yhteysmedia vaativat PCU:n ja muiden GPRS-verkon yksiköiden välisistä yhteyksistä huolehtivien ohjelman osien, viestintäajurien uuden toteutuksen. Tämän työn tuloksena syntyivät tarvittavien viestintäajurien työasemaversiot. Työssä tarkastellaan eri tiedonsiirtotapoja ja -protokollia testattavan ohjelmiston vaateiden, toteutetun ajurin ja testauksen kannalta. Työssä esitellään kunkin ajurin toteuttama rajapinta ja toteutuksen aste, eli mitkä toiminnot on toteutettu ja mitä on jätetty pois. Ajureiden rakenne ja toiminta selvitetään siltä osin, kuin se on oleellista ohjelman toiminnan kannalta.

Market Orientation in Rapidly Internationalizing Small Companies — Evidence from the Software Industry

For more than a decade, researchers have been aware of the increased pace of small-firm internationalization and the greater effect of these rapidly growing small businesses on the wealth, international trade, and job-creation opportunities of countries. Due to the small size of the home market, Finnish companies have been generally considered highly interested in internationalization. One particular domain in which rapid internationalization has been considered feasible is the global software business, with its knowledge-intensive nature and high growth potential. However, over time the failure rate of small entrepreneurial firms has remained especially high in high-technology markets. One of the reasons for this seems to lie in the fact that these companies are often formed by people with a strong technological background but limited competences in other areas. Further, research on the marketing capabilities of rapidly internationalizing high-tech firms has been scarce thus far. In addition, while there is much research on the first years of operations of rapidly internationalizing companies, it is not well known what becomes of them later on. Therefore, there is a need for more investigation into the managerial mindset, competences and decision-making in these small companies, especially from the perspective of how they acquire and exploit market knowledge, and enhance their networking capabilities in order to promote international expansion. The present study focuses on market orientation in small software firms that internationalize their operations rapidly in global software markets. It builds on qualitative data to illustrate how these companies develop their market-oriented product-market strategies during the process of increasing international commitment. It also shows how they manage their network relationships in order to be able to offer better customer service and to thrive in the fierce global competition. The study was conducted in the empirical context of Finnish small software companies, and the main data consists of interviews with top managers in these businesses. The interviews were designed to cover a minimum period of five years of the company's international operations, thus offering a retrospective in-depth perspective on market orientation, internationalization and partnerships in the given context. One particular focus is on less successfully internationalized software companies, and the challenges they face when approaching international markets. This study makes a significant contribution to the literature on market orientation for several reasons. First, building on data from the software industry, it clarifies the existing theory in the context of rapid internationalization and network relationships. Secondly, it provides a good body of evidence on market orientation in both successfully and less successfully internationalized companies, and identifies the key related differences between the two company groups. Thirdly, it highlights the importance of inter-firm networks in the rapid internationalization of small software firms, providing companies with important market knowledge and, in some cases, management challenges. Fourthly, this investigation clarifies market orientation in the context of different software-product strategies, thus, combining the perspectives of market orientation in both manufacturing and services. In sum, the results of the study are significant for both small software firms and public-policy makers since they shed light on the market-oriented managerial mindset and the market-information gathering and sharing processes that are needed in successful rapid internationalization.

False normal Lung Clearance Index in infants with cystic fibrosis due to software algorithms.

BACKGROUND: Lung clearance index (LCI), a marker of ventilation inhomogeneity, is elevated early in children with cystic fibrosis (CF). However, in infants with CF, LCI values are found to be normal, although structural lung abnormalities are often detectable. We hypothesized that this discrepancy is due to inadequate algorithms of the available software package. AIM: Our aim was to challenge the validity of these software algorithms. METHODS: We compared multiple breath washout (MBW) results of current software algorithms (automatic modus) to refined algorithms (manual modus) in 17 asymptomatic infants with CF, and 24 matched healthy term-born infants. The main difference between these two analysis methods lies in the calculation of the molar mass differences that the system uses to define the completion of the measurement. RESULTS: In infants with CF the refined manual modus revealed clearly elevated LCI above 9 in 8 out of 35 measurements (23%), all showing LCI values below 8.3 using the automatic modus (paired t-test comparing the means, P < 0.001). Healthy infants showed normal LCI values using both analysis methods (n = 47, paired t-test, P = 0.79). The most relevant reason for false normal LCI values in infants with CF using the automatic modus was the incorrect recognition of the end-of-test too early during the washout. CONCLUSION: We recommend the use of the manual modus for the analysis of MBW outcomes in infants in order to obtain more accurate results. This will allow appropriate use of infant lung function results for clinical and scientific purposes. Pediatr Pulmonol. 2015; 50:970-977. © 2015 Wiley Periodicals, Inc.

Evaluation of Software Development Practices through Error Analysis

This thesis studies evaluation of software development practices through an error analysis. The work presents software development process, software testing, software errors, error classification and software process improvement methods. The practical part of the work presents results from the error analysis of one software process. It also gives improvement ideas for the project. It was noticed that the classification of the error data was inadequate in the project. Because of this it was impossible to use the error data effectively. With the error analysis we were able to show that there were deficiencies in design and analyzing phases, implementation phase and in testing phase. The work gives ideas for improving error classification and for software development practices.

From Educational Segregation to Transformative Inclusion

Recent studies conducted in Europe using communicative methodology highlight that different ways of grouping students has a direct effect on their academic output. This article analyzes how said research methodology identifies and analyzes those student groupings that provide greater academic success and improve classroom coexistence at Spanish educational centers. Said methodology entails all of the research participants researchers, teachers, families, and students reflecting on the consequences of streaming, mixture, and inclusion for student academic achievement. Following this, our conclusions are compared with the policies and educational practices implemented in Spanish schools, which are not based on scientific knowledge and do not usually lead to academic success. Finally, recommendations are presented for future educational policies with the aim of providing an alternative for teachers and educational managers that would substantially improve student academic success.

MRI/TRUS fusion software-based targeted biopsy: the new standard of care?

The advent of multiparametric MRI has made it possible to change the way in which prostate biopsy is done, allowing to direct biopsies to suspicious lesions rather than randomly. The subject of this review relates to a computer-assisted strategy, the MRI/US fusion software-based targeted biopsy, and to its performance compared to the other sampling methods. Different devices with different methods to register MR images to live TRUS are currently in use to allow software-based targeted biopsy. Main clinical indications of MRI/US fusion software-based targeted biopsy are re-biopsy in men with persistent suspicious of prostate cancer after first negative standard biopsy and the follow-up of patients under active surveillance. Some studies have compared MRI/US fusion software-based targeted versus standard biopsy. In men at risk with MRI-suspicious lesion, targeted biopsy consistently detects more men with clinically significant disease as compared to standard biopsy; some studies have also shown decreased detection of insignificant disease. Only two studies directly compared MRI/US fusion software-based targeted biopsy with MRI/US fusion visual targeted biopsy, and the diagnostic ability seems to be in favor of the software approach. To date, no study comparing software-based targeted biopsy against in-bore MRI biopsy is available. The new software-based targeted approach seems to have the characteristics to be added in the standard pathway for achieving accurate risk stratification. Once reproducibility and cost-effectiveness will be verified, the actual issue will be to determine whether MRI/TRUS fusion software-based targeted biopsy represents anadd-on test or a replacement to standard TRUS biopsy.

Decreasing educational differences in mortality over 40 years: evidence from the Turin Longitudinal Study (Italy)

BACKGROUND: Recent studies suggest that inequalities in premature mortality have continued to rise over the last decade in most European countries, but not in southern European countries. METHODS: In this study, we assess long-term trends (1971-2011) in absolute and relative educational inequalities in all-cause and cause-specific mortality in the Turin Longitudinal Study (Turin, Italy), a record-linkage study including all individuals resident in Turin in the 1971, 1981, 1991 and 2001 censuses, and aged 30-99 years (more than 2 million people). We examined mortality for all causes, cardiovascular disease (CVD), all cancers and specific cancers (lung, breast), as well as smoking and alcohol-related mortality. RESULTS: Overall mortality substantially decreased in all educational groups over the study period, although cancer rates only slightly declined. Absolute inequalities decreased for both genders (SII=962/694 in men/women in 1972-1976 and SII=531/259 in 2007-2011, p<0.01). Among men, absolute inequalities for CVD and alcohol-related causes declined (p<0.05), while remaining stable for other causes of death. Among women, declines in absolute inequalities were observed for CVD, smoking and alcohol-related causes and lung cancer (p<0.05). Relative inequalities in all-cause mortality remained stable for men and decreased for women (RII=1.92/2.03 in men/women in 1972-1976 and RII=2.15/1.32 in 2007-2011). Among men, relative inequalities increased for smoking-related causes, while among women they decreased for all cancers, CVD, smoking-related causes and lung cancer (p<0.05). CONCLUSIONS: Absolute inequalities in mortality strongly declined over the study period in both genders. Relative educational inequalities in mortality were generally stable among men; while they tended to narrow among women. In general, this study supports the hypothesis that educational inequalities in mortality have decreased in southern European countries.

Implementing Agile Software Development Methods in a Small Organization

Currently there is a vogue for Agile Software Development methods and many software development organizations have already implemented or they are planning to implement agile methods. Objective of this thesis is to define how agile software development methods are implemented in a small organization. Agile methods covered in this thesis are Scrum and XP. From both methods the key practices are analysed and compared to waterfall method. This thesis also defines implementation strategy and actions how agile methods are implemented in a small organization. In practice organization must prepare well and all needed meters are defined before the implementation starts. In this work three different sample projects are introduced where agile methods were implemented. Experiences from these projects were encouraging although sample set of projects were too small to get trustworthy results.
