On the Application of Beam on Elastic Foundation Theory to the Analysis of Stiffened Plate Strips

The main objective of this thesis is to show that plate strips subjected to transverse line loads can be analysed by using the beam on elastic foundation (BEF) approach. It is shown that the elastic behaviour of both the centre line section of a semi infinite plate supported along two edges, and the free edge of a cantilever plate strip can be accurately predicted by calculations based on the two parameter BEF theory. The transverse bending stiffness of the plate strip forms the foundation. The foundation modulus is shown, mathematically and physically, to be the zero order term of the fourth order differential equation governing the behaviour of BEF, whereas the torsion rigidity of the plate acts like pre tension in the second order term. Direct equivalence is obtained for harmonic line loading by comparing the differential equations of Levy's method (a simply supported plate) with the BEF method. By equating the second and zero order terms of the semi infinite BEF model for each harmonic component, two parameters are obtained for a simply supported plate of width B: the characteristic length, 1/ λ, and the normalized sum, n, being the effect of axial loading and stiffening resulting from the torsion stiffness, nlin. This procedure gives the following result for the first mode when a uniaxial stress field was assumed (ν = 0): 1/λ = √2B/π and nlin = 1. For constant line loading, which is the superimposition of harmonic components, slightly differing foundation parameters are obtained when the maximum deflection and bending moment values of the theoretical plate, with v = 0, and BEF analysis solutions are equated: 1 /λ= 1.47B/π and nlin. = 0.59 for a simply supported plate; and 1/λ = 0.99B/π and nlin = 0.25 for a fixed plate. The BEF parameters of the plate strip with a free edge are determined based solely on finite element analysis (FEA) results: 1/λ = 1.29B/π and nlin. = 0.65, where B is the double width of the cantilever plate strip. The stress biaxial, v > 0, is shown not to affect the values of the BEF parameters significantly the result of the geometric nonlinearity caused by in plane, axial and biaxial loading is studied theoretically by comparing the differential equations of Levy's method with the BEF approach. The BEF model is generalised to take into account the elastic rotation stiffness of the longitudinal edges. Finally, formulae are presented that take into account the effect of Poisson's ratio, and geometric non linearity, on bending behaviour resulting from axial and transverse inplane loading. It is also shown that the BEF parameters of the semi infinite model are valid for linear elastic analysis of a plate strip of finite length. The BEF model was verified by applying it to the analysis of bending stresses caused by misalignments in a laboratory test panel. In summary, it can be concluded that the advantages of the BEF theory are that it is a simple tool, and that it is accurate enough for specific stress analysis of semi infinite and finite plate bending problems.

The Detector Control Systems for the CMS Resistive Plate Chamber at LHC

The RPC Detector Control System (RCS) is the main subject of this PhD work. The project, involving the Lappeenranta University of Technology, the Warsaw University and INFN of Naples, is aimed to integrate the different subsystems for the RPC detector and its trigger chain in order to develop a common framework to control and monitoring the different parts. In this project, I have been strongly involved during the last three years on the hardware and software development, construction and commissioning as main responsible and coordinator. The CMS Resistive Plate Chambers (RPC) system consists of 912 double-gap chambers at its start-up in middle of 2008. A continuous control and monitoring of the detector, the trigger and all the ancillary sub-systems (high voltages, low voltages, environmental, gas, and cooling), is required to achieve the operational stability and reliability of a so large and complex detector and trigger system. Role of the RPC Detector Control System is to monitor the detector conditions and performance, control and monitor all subsystems related to RPC and their electronics and store all the information in a dedicated database, called Condition DB. Therefore the RPC DCS system has to assure the safe and correct operation of the sub-detectors during all CMS life time (more than 10 year), detect abnormal and harmful situations and take protective and automatic actions to minimize consequential damages. The analysis of the requirements and project challenges, the architecture design and its development as well as the calibration and commissioning phases represent themain tasks of the work developed for this PhD thesis. Different technologies, middleware and solutions has been studied and adopted in the design and development of the different components and a big challenging consisted in the integration of these different parts each other and in the general CMS control system and data acquisition framework. Therefore, the RCS installation and commissioning phase as well as its performance and the first results, obtained during the last three years CMS cosmic runs, will be

The Digital Book as a Disruptive Innovation

Whether digital book will become the dominant design of books and be a widely accepted format for reading is a question that is currently asked by every e-publisher, publishing industry worker and many book consumers. This study is the first to holistically approach Christensen’s disruptive innovation theory for an instrument of measuring the phenomenon of the digital book. The disruptiveness of an innovation could be measured by it’s disruptive potential and the disruption process it passes. The empirical part of the thesis is designed so to investigate the digital book‘s features as an innovation for disruptive potential and then the current digital book market, monitoring it for disruption processes. Proving that the digital book is a disruptive innovation may allow understanding it’s prospects and even help in making a pattern of the innovation’s market infiltration in the future. The framework created for answering the research question could also be used in a similar way to analyze other E-publishing products (e.g. e-newspapers, emagazines).

Open-book accounting - hyödyt ja haasteet erityyppisissä liiketoimintasuhteissa

Tutkimuksessa tarkastellaan OBA:n soveltamisen hyötyjä ja haasteita erityyppisissä yritysten välisissä suhteissa.Tutkimuksen tavoitteena on vastata kysymykseen, mitä erilaisia tavoitteita liiketoimintasuhteiden taustalla esiintyy, tyypitellä liiketoimintasuhteet tavoitteiden ja yritysten välisten toimintojen näkökulmasta ja arvioida miten OBA voi auttaa erityyppisien suhteiden johtamista tukevan informaation tuottamisessa ja hyödyntämisessä. Markkinaperustaisissa suhteissa vaihdannan avulla tavoitellaan tehokkuutta jonka perustana on markkinoilla vallitsevan kilpailun tehokkuus. Neuvotteluvoimaan perustuvissa suhteissa tavoitteena on hankkia resursseja sisäisiä tuotantokustannuksia edullisemmin markkinavoimaa hyväksikäyttämällä. Yhteistyösuhteissa toimittajan kyky tuottaa resurssi sisäisiin tuotantokustannuksiin nähden kilpailukykyisellä hinnalla perustuu vallitseviin mittakaavaetuihin tai erikoistumisen tuomaan osaamiseen ja niissä pyritään saavuttamaan kilpailuetua yritysten osaamista ja resursseja yhdistämällä. Yhteistyösuhteet voidaan jakaa operatiivisiin, taktisiin ja strategisiin yritysten välisten toimintojen integroituneisuuden ja strategisen merkityksen perusteella. Tutkimus antaa viitteitä siitä että OBA:n soveltamisen suurin potentiaali liittyy taktisiin ja strategisiin yhteistyösuhteisiin, koska niissä yritysten välisten toimintojen määrä on merkittävä ja yhteiset tavoitteet lisäävät yritysten välistä luottamusta.

Tragicall Historie and Phantasticall Trifles: On Evaluation of the Book in Sixteenth-Century Translators’ Paratexts

Tässä tutkielmassa tarkastelen kirjoihin ja kirjallisuuteen kohdistuvaa arvottavaa kieltä 1500-luvun Britanniassa. Tutkielman tavoitteena on selvittää, millaisia positiivisia ja negatiivisia evaluaatioita esiintyy kääntäjien parateksteissä ja mitä nämä ilmaukset kertovat kirjan arvostuksesta aikalaisyhteiskunnassa. Genetten mukaan paratekstien tarkoitus on paitsi antaa lukijalle informaatiota tekstistä, myös ohjata teoksen luentaa ja vaikuttaa tekstin tarjoaman tulkinnan vastaanottoon. Tutkielman materiaalina käytettyjä kuuttatoista paratekstiä, tarkemmin sanottuna prologia tai dedikaatiota, on lähestytty lähiluennan kautta. Luennassa keskityttiin ilmauksiin, joilla tuodaan esiin kirjoihin ja kirjallisuuteen liittyviä asenteita ja arvotuksia. Näin kerätyt evaluoivat ilmaukset analysoin Martinin ja Whiten kehittämän, systeemis-funktionaalisen kieliopin tutkimusperinteestä syntyneen Appraisal Framework-mallin avulla. Tämän teoreettisen viitekehyksen etuna on leksikaalinen lähestymistapa, joka verrattuna muihin arvottavaa kieltä pääasiallisesti kieliopillisista näkökulmista kartoittaviin teorioihin kattaa suuremaan esiintymäkentän. Analyysin alussa materiaalin evaluaatiota käsittelevät ilmaukset jaetaan kahteen ryhmään: kirjaa arvottavat sekä kirjan tekijöitä ja taustahahmoja, tavallisesti kirjailijaa ja kääntäjää, arvottavat ilmaukset. Tutkimuksen perusteella voidaan todeta että kirjaa ja kirjailijaa arvottavista ilmauksista tyypillisimpiä ovat paratekstin genrevaatimusten sanelemat positiivisen evaluaation ilmaukset. Kirjaa evaluoidaan muun muassa tyylin, sisällön ja tekstin vaikutusten osalta. Käännöstä ja kääntäjää evaluoivien ilmausten havaittiin muodostavan oman ryhmänsä, jossa tyypillisin evaluoiva ilmaus on eksplisiittisen kielteinen, mutta jossa myös esiintyy positiivisia ilmauksia. Käännökseen ja kääntäjään kohdistuvaa positiivista evaluaatiota esiintyy implisiittisessä, ideationaaliseen viestiin nojaavassa diskurssissa. Lukijalle tarjotaan kahta eri evaluatiivista viestiä. Tästä johtuen tutkielmassa katsotaan, että kirjaan kohdistuva evaluaatio on olevan pääasiallisesti epäluotettavaa, ja että hedelmällisimmät tulokset tutkiessa aikalaiskäsityksiä kirjallisuudesta on löydettävissä implisiittisistä- sekä kiertoilmauksista.

Composite artistry in the Book of Numbers : a study in biblical narrative conventions

The present thesis discusses the coherence or lack of coherence in the book of Numbers, with special regard to its narrative features. The fragmented nature of Numbers is a well-known problem in research on the book, affecting how we approach and interpret it, but to date there has not been any thorough investigation of the narrative features of the work and how they might contribute to the coherence or the lack of coherence in the book. The discussion is pursued in light of narrative theory, and especially in connection to three parameters that are typically understood to be invoked in the interpretation of narratives: 1) a narrative paradigm, or ‘story,’ meaning events related to each other temporally, causally, and thematically, in a plot with a beginning, middle, and end; 2) discourse, being the expression plane of a narrative, or the devices that an author has at hand in constructing a narrative; 3) the situation or languagegame of the narrative, prototypical examples being factual reports, which seeks to depict a state of affairs, and storytelling narratives, driven by a demand for tellability. In view of these parameters the present thesis argues that it is reasonable to form four groups to describe the narrative material of Numbers: genuine narratives (e.g. Num 12), independent narrative sequences (e.g. Num 5:1-4), instrumental scenes and situations (e.g. Num 27:1-5), and narrative fragments (e.g. Num 18:1). These groups are mixed throughout with non-narrative materials. Seen together, however, the narrative features of these groups can be understood to create an attenuated narrative sequence from beginning to end in Numbers, where one thing happens after another. This sequence, termed the ‘larger story’ of Numbers, concerns the wandering of Israel from Sinai to Moab. Furthermore, the larger story has a fragmented plot. The end-point is fixed on the promised land, Israel prepares for the wandering towards it (Num 1-10), rebels against wandering and the promise and is sent back into the wilderness (Num 13-14), returns again after forty years (Num 21ff.), and prepares for conquering the land (Num 22-36). Finally, themes of the promised land, generational succession, and obedience-disobedience, operate in this larger story. Purity is also a significant theme in the book, albeit not connected to plot in the larger story. All in all, sequence, plot, and theme in the larger story of Numbers can be understood to bring some coherence to the book. However, neither aspect entirely subsumes the whole book, and the four groups of narrative materials can also be understood to underscore the incoherence of the work in differentiating its variegated narrative contents. Numbers should therefore be described as an anthology of different materials that are loosely connected through its narrative features in the larger story, with the aim of informing Israelite identity by depicting a certain period in the early history of the people.

Intensification of Operation of Inclined Plate Settler at Fertilizer Plant

Fertilizer plant’s process waters contain high concentrations of nitrogen compounds, such as ammonium and nitrate. Phosphorus and fluorine, which originate from phosphoric acid and rock phosphate (apatite) used in fertilizer production, are also present. Phosphorus and nitrogen are the primary nutrients causing eutrophication of surface waters. At fertilizer plant process waters are held in closed internal circulation. In a scrubber system process waters are used for washing exhaust gases from fertilizer reactors and dry gases from granulation drums as well as for cooling down the fertilizer slurry in neutralization reactor. Solids in process waters are separated in an inclined plate settler by gravitational sedimentation. However, the operation of inclined plate settler has been inadequate. The aim of this thesis was to intensify the operation of inclined plate settler and thus the solids separation e.g. through coagulation and/or flocculation process. Chemical precipitation was studied to reduce the amount of dissolved species in process waters. Specific interest was in precipitation of nitrogen, phosphorus, and fluorine containing specimens. Amounts of phosphorus and fluorine were reduced significantly by chemical precipitation. When compared to earlier studies, annual chemical costs were almost eight times lower. Instead, nitrogen compounds are readily dissolved in water, thus being difficult to remove by precipitation. Possible alternative techniques for nitrogen removal are adsorption, ion exchange, and reverse osmosis. Settling velocities of pH adjusted and flocculated process waters were sufficient for the operation of inclined plate settler. Design principles of inclined plate settler are also presented. In continuation studies, flow conditions in inclined plate settler should be modelled with computational fluid dynamics and suitability of adsorbents, ion exchange resins, and membranes should be studied in laboratory scale tests.
