Tilaus-toimitusprosessin johtaminen, suorituskyky, mittaaminen ja mittarit

Tämä tutkimus perustuu prosessijohtamiseen ja tilaus-toimitusprosessin suorituskyvyn mittaamiseen. Tutkimusongelmaa lähestytään toiminta-analyyttisen ja konstruktiivisen tutkimusotteen avulla. Toiminta-analyyttinen tutkimusote vaatii tutkimusongelmaan liittyvään teoriaan perehtymistä ja suosituksia toimenpiteistä. Tämän vuoksi tutkimuksessa on syvennytty aikaisempiin suorituskykyä sekä prosessijohtamista koskeviin teorioihin ja tutkimusraportteihin, jotta löydettäisiin case-yrityksen näkökulmasta vastauksia esitettyihin tutkimuskysymyksiin. Tutkimuksen tarkoituksena on analysoida case-yrityksen tilaus-toimitusprosessin johtamista ja prosessin suorituskykyyn vaikuttavia tekijöitä. Tavoitteena on löytää sellaisia suorituskyvyn osa-alueita, joiden mittaaminen tuottaa helpoiten ja nopeasti tietoa päätöksenteon tueksi sekä tilaus-toimituksen johtamista varten. Toisena tavoitteena on selvittää, millaisilla mittareilla yrityksen suorituskykyä voidaan mitata. Tutkimuksessa hyödynnetään toiminta-analyyttistä ja konstruktiivista tutkimusotetta sekä otteisiin liittyviä eri tutkimusmenetelmiä. Tutkimuksen lähestymistapa perustuu pk-yrityksen lähtökohtiin. Koska työssä tarkastellaan suorituskykyä sisäisen suorituskyvyn näkökulmasta, työssä esitellään sisäisen suorituskyvyn eri osa-alueita. Kansainvälisen tutkimuksen mukaan pk-yritykselle tärkeitä sisäisen suorituskyvyn osa-alueita ovat aika, joustavuus, laatu, talous, asiakastyytyväisyys sekä henkilöstön osaaminen ja innovatiivisuus. Tässä tutkimuksessa edellä mainitut suorituskyvyn osa-alueet todennettiin tärkeiksi, kun analysoitiin case-yrityksen tilaus-toimituksen kriittisiä menestystekijöitä. Tutkimustyön tuloksena rakennettiin yksinkertainen ja helppokäyttöinen mittaristo sekä analysointimenetelmä, jonka avulla on mahdollista seurata tilaus-toimitusprosessin suorituskykyä. Mittaristo rakennettiin SAKE-suorituskyvyn analysointijärjestelmän pohjalle.

Todennäköisyyspohjaisen kaapelipaloriskianalyysimenetelmän kehittäminen ydinvoimalaitokselle

Ydinenergian tuottamisessa turvallisuus on tärkeää. Todennäköisyyspohjaisella riskianalyysillä voidaan arvioida turvallisuusvaatimusten täyttymistä eri tilanteissa. Tässä diplomityössä tarkastellaan todennäköisyyspohjaisen riskianalyysin käyttöä ydinvoimalaitoksen kaapelipalojen vaikutusten arvioinnissa. Työn tarkoituksena on omalta osaltaan edistää ydinvoimalaitosten kaapelipaloturvallisuuden parantamista. Työssä esitellään todennäköisyyspohjaisen riskianalyysin ja todennäköisyyspohjaisen paloanalyysin periaatteet sekä nykyiset kaapelipaloanalyysimenetelmät. Olemassa olevien menetelmien pohjalta kehitettiin menetelmä Olkiluoto 1 ja 2 laitosyksiköiden kaapelipaloturvallisuuden arviointiin. Työssä tarkastellaan myös maailmalla sattuneita kaapelipaloja sekä ydinvoimalaitosten palosimulointiin kehitettyä ohjelmistoa. Työssä kehitetty kaapelipaloanalyysi jakautuu kahteen päävaiheeseen: virtapiirien vika-analyysiin ja virtapiirivikojen todennäköisyysanalyysiin. Virtapiirien vika-analyysi käsittää kaapeleiden vikamoodien, virtapiirien vikaantumisluokkien sekä vikaantumisten vaikutuksien määrittämisen. Virtapiirivikojen todennäköisyysanalyysissä määritetään puolestaan vikaantumistodennäköisyydet kaapelipalokokeiden tulosten pohjalta. Kehitettyä analyysimenetelmää sovellettiin esimerkinomaisesti Olkiluoto 1 ja 2 laitosyksiköiden kahdelle eri huonetilalle. Tuloksena saatiin turvallisuudelle tärkeiden järjestelmien virtapiirien vikaantumismallit sekä niiden todennäköisyydet. Tulosten perusteella voidaan todeta, että työssä kehitetty kaapelipaloanalyysimenetelmä toimi hyvin. Tulevaisuudessa menetelmää on tarkoitus hyödyntää Olkiluoto 1 ja 2 -laitosyksiköiden kaapelipaloturvallisuuden arvioinnissa.

Optimized dark matter searches in deep observations of Segue 1 with MAGIC

We present the results of stereoscopic observations of the satellite galaxy Segue 1 with the MAGIC Telescopes, carried out between 2011 and 2013. With almost 160 hours of good-quality data, this is the deepest observational campaign on any dwarf galaxy performed so far in the very high energy range of the electromagnetic spectrum. We search this large data sample for signals of dark matter particles in the mass range between 100 GeV and 20 TeV. For this we use the full likelihood analysis method, which provides optimal sensitivity to characteristic gamma-ray spectral features, like those expected from dark matter annihilation or decay. In particular, we focus our search on gamma-rays produced from different final state Standard Model particles, annihilation with internal bremsstrahlung, monochromatic lines and box-shaped signals. Our results represent the most stringent constraints to the annihilation cross-section or decay lifetime obtained from observations of satellite galaxies, for masses above few hundred GeV. In particular, our strongest limit (95% confidence level) corresponds to a ~ 500 GeV dark matter particle annihilating into τ+τ−, and is of order langleσannvrangle simeq 1.2 × 10−24 cm3 s−1 a factor ~ 40 above the langleσannvrangle simeq thermal value.

Anàlisi de la incidència del sistema de joc en la creació de situacions de superioritat numèrica en el futbol amb el juvenil “A” del Futbol Club Barcelona

El present treball es centra en l’estudi de les situacions de superioritat numèrica generades al llarg de la temporada 2013-2014 de l’equip Juvenil A del Futbol Club Barcelona. L’objectiu principal d’aquest treball és esbrinar quina incidència té el sistema de joc 1-4-3-3 en la creació d’aquestes situacions ofensives en el joc de l’equip. Per tal d’enregistrar múltiples situacions de joc i diferenciar la seva complexitat, s’han establert tres variables d’estudi: la zona del camp on es crea la superioritat numèrica (dividint el camp en 12 zones), el tipus de superioritat produïda (2 contra 1, 3 contra 1, 3 contra 2, 4 contra 2 i 4 contra 3), i la freqüència d’interacció dels jugadors en les situacions de superioritat en relació al networking (jugadors que intervenen en les situacions de superioritat per tal de poder establir relacions entre posicions del sistema de joc 1-4-3-3). El mètode utilitzat és notacional (ja que s’enregistra la freqüència en què succeeix un fenomen a partir d’unes taules creades especialment per l’enregistrament de dades), on fent ús de la proposta de Gréhaigne (2001) s’analitzen 8 partits al llarg de la temporada 2013-2014. Els resultats obtinguts mostren que es produeixen més superioritats a les zones 4 i 6 (20,37% respectivament), seguides de les zones 7 (14,81%) i 5 (13,89%). El major tipus de superioritat ha estat el 2 contra 1 (48,15%) seguit del 3 contra 2 (39,81%). La interacció més freqüent entre jugadors en les situacions de 2 contra 1 ha estat: lateral dret i central dret (26,92%) i lateral esquerre i central esquerre (21,15%). En les situacions de tres jugadors (3 contra 1) ha estat: entre el central dret, central esquerre i el pivot (28,57%) i entre el central dret, el lateral dret i el pivot (28,75%). En les situacions de 3 contra 2: lateral dret, l’interior dret i l’extrem dret (18,60%) i entre el central esquerre, el lateral esquerre i l’interior esquerre (18,60%). Pel que fa a les situacions de 4 contra 2 no se n’ha produït cap, i les de 4 contra 3 hi ha una igualtat entre diverses posicions(16,67%), però no s’observen dades molt significatives en quan a la intervenció, excepte la posició del pivot que intervé en gairebé totes. Aquestes dades, s’assimilen al que diuen Sans i Frattarola (2009) sobre el fet que en la zona d’inici es creen més situacions de superioritat que en la zona de progressió i finalització. També Castelo (1999) aporta un estudi sobre els percentatges d’aportacions ofensives dels jugadors en funció de l’espai i la demarcació, però tot i que en aquest cas no ho compara amb situacions de superioritat numèrica, les dades extretes son interessants per la comparativa amb l’estudi que es presenta.

Pulmonary 64-MDCT angiography with 50 mL of iodinated contrast material in an unselected patient population: a feasible protocol

Abstract Objective: To propose a protocol for pulmonary angiography using 64-slice multidetector computed tomography (64-MDCT) with 50 mL of iodinated contrast material, in an unselected patient population, as well as to evaluate vascular enhancement and image quality. Materials and Methods: We evaluated 29 patients (22-86 years of age). The body mass index ranged from 19.0 kg/m2 to 41.8 kg/m2. Patients underwent pulmonary CT angiography in a 64-MDCT scanner, receiving 50 mL of iodinated contrast material via venous access at a rate of 4.5 mL/s. Bolus tracking was applied in the superior vena cava. Two experienced radiologists assessed image quality and vascular enhancement. Results: The mean density was 382 Hounsfield units (HU) for the pulmonary trunk; 379 and 377 HU for the right and left main pulmonary arteries, respectively; and 346 and 364 HU for the right and left inferior pulmonary arteries, respectively. In all patients, subsegmental arteries were analyzed. There were streak artifacts from contrast material in the superior vena cava in all patients. However, those artifacts did not impair the image analysis. Conclusion: Our findings suggest that pulmonary angiography using 64-MDCT with 50 mL of iodinated contrast can produce high quality images in unselected patient populations.

Innovaatioyliopisto” mediassa – Innovatiivisuuden merkitykset TKK:n, HKKK:n ja TaiK:n fuusiota koskevassa lehtikirjoittelussa

Sanomalehdissä käyty keskustelu “innovaatioyliopistosta” eli Helsinkiin sijoittuvasta Teknillisen korkeakoulun, Helsingin kauppakorkeakoulun ja Taideteollisen korkeakoulun fuusiohankkeesta on ollut vilkasta. Työnimestä huolimatta sisällöllinen keskustelu innovatiivisuudesta on ollut vähäistä. Tämän työn tutkimusmetodi on diskurssianalyysi. Sen keinoin pureudutaan innovatiivisuuden merkityksentymiseen yliopistofuusion kontekstissa. Laajasta kuuden sanomalehden artikkeliaineistosta vuosina 2005-2008 on valittu innovaatiodiskurssia edustava pääaineisto, jota on tulkittu sosiaalisesta ja kielellisestä näkökulmasta käsin. Innovatiivisuus yliopistokontekstissa merkityksentyi pääasiassa innovaatiojärjestelmien kautta. Perustutkimuksen tärkeä rooli innovaatioketjussa esittäytyi näkyvästi.

Blood pressure levels and haematoma growth in patients with Intracerebral Haemorrhage (ICH) A retrospective observational study

Intracerebral haemorrhage (ICH) is a spontaneous extravasation of blood into brain parenchyma. Although ICH represents approximately only 15% of all strokes, it is one of the major causes of stroke-related death and disability. One of the causes of poor outcome is the haematoma growth. The association between elevated blood pressure (BP) and haematoma enlargement in acute ICH has not been clarified. Our objective is to try to identify this relationship that may suggest an immediate target for intervention to possibly improve outcomes in patients with spontaneous ICH and might settle the controversy surrounding the optimal management of blood pressure.We propose a retrospective revision using a sample present in our database of approximately 250 patients with primary ICH and less than 12h from symptoms onset. Systolic blood pressure levels (SBP) are assessed at baseline, at 6h, at 12h, at 24h and at 72h, being these last four the average levels of the different recordings during those time intervals. Haematoma growth will be defined as an increase in the volume of intraparenchymal haemorrhage of >33% as measured by image analysis on the 24-hour CT or 72-hour CT compared with the baseline CT scan. A qualified neuroradiologist not informed of the aim of the study, will review the CT images. The secondary objective will be to correlate the BP levels in the acute phase of ICH with clinical outcome. We will evaluate early neurologic deterioration at 72h by using the National Institutes of Health Stroke Scale (NIHSS); outcome at 90 days by using the modified Rankin scale and mortality at 72h and 90 days. The statistical analysis will be adjusted by possibly confounding variables

Matalan tason tapahtumien tutkintaan kehitettiin kysymyslista, jolla saadaan helposti selville tapahtumien ongelma-alueet. Kysymyslista mahdollisti myös tapahtumien laaja-alaisen luokittelun, jonka avulla tunnistetaan eri tapahtumien kautta ilmenneitä yhteisiä ongelma-alueita. Tapahtumien tutkintaan liittyy myös riskien arviointi. Tässä diplomityössä kehitettiin riskimatriisi tapahtuman vakavuuden ja jatkoselvitystarpeen arvioinnin avuksi. Perussyyanalyysimenetelmistä AcciMap-menetelmä osoittautui käyttökelpoiseksi ja sitä suositellaan kokeiltavaksi seuraavan inhimilliseen toimintaan liittyvän perussyyanalyysin yhteydessä.

Role of references in international industrial marketing : a theory-building case study about supplier’s processes of utilizing references

Scientific studies regarding specifically references do not seem to exist. However, the utilization of references is an important practice for many companies involved in industrial marketing. The purpose of the study is to increase the understanding about the utilization of references in international industrial marketing in order to contribute to the development of a theory of reference behavior. Specifically, the modes of reference usage in industry, the factors affecting a supplier's reference behavior, and the question how references are actually utilized, are explored in the study. Due to the explorative nature of the study, a research design was followed where theory and empirical studies alternated. An Exploratory Framework was developed to guide a pilot case study that resulted in Framework 1. Results of the pilot study guided an expanded literature review that was used to develop first a Structural Framework and a Process Framework which were combined in Framework 2. Then, the second empirical phase of the case study was conducted in the same (pilot) case company. In this phase, Decision Systems Analysis (DSA) was used as the analysis method. The DSA procedure consists of three interviewing waves: initial interviews, reinterviews, and validating interviews. Four reference decision processes were identified, described and analyzed in the form of flowchart descriptions. The flowchart descriptions were used to explore new constructs and to develop new propositions to develop Framework 2 further. The quality of the study was ascertained by many actions in both empirical parts of the study. The construct validity of the study was ascertained by using multiple sources of evidence and by asking the key informant to review the pilot case report. The DSA method itself includes procedures assuring validity. Because of the choice to conduct a single case study, external validity was not even pursued. High reliability was pursued through detailed documentation and thorough reporting of evidence. It was concluded that the core of the concept of reference is a customer relationship regardless of the concrete forms a reference might take in its utilization. Depending on various contingencies, references might have various tasks inside the four roles of increasing 1) efficiency of sales and sales management, 2) efficiency of the business, 3) effectiveness of marketing activities, and 4) effectiveness in establishing, maintaining and enhancing customer relationships. Thus, references have not only external but internal tasks as well. A supplier's reference behavior might be affected by many hierarchical conditions. Additionally, the empirical study showed that the supplier can utilize its references as a continuous, all pervasive decision making process through various practices. The process includes both individual and unstructured decision making subprocesses. The proposed concept of reference can be used to guide a reference policy recommendable for companies for which the utilization of references is important. The significance of the study is threefold: proposing the concept of reference, developing a framework of a supplier's reference behavior and its short term process of utilizing references, and conceptual structuring of an unstructured and in industrial marketing important phenomenon to four roles.

Threshold Selection Criteria for Quantification of Lumbosacral Cerebrospinal Fluid and Root Volumes from MRI

BACKGROUND AND PURPOSE: The high variability of CSF volumes partly explains the inconsistency of anesthetic effects, but may also be due to image analysis itself. In this study, criteria for threshold selection are anatomically defined. METHODS: T2 MR images (n = 7 cases) were analyzed using 3-dimentional software. Maximal-minimal thresholds were selected in standardized blocks of 50 slices of the dural sac ending caudally at the L5-S1 intervertebral space (caudal blocks) and middle L3 (rostral blocks). Maximal CSF thresholds: threshold value was increased until at least one voxel in a CSF area appeared unlabeled and decreased until that voxel was labeled again: this final threshold was selected. Minimal root thresholds: thresholds values that selected cauda equina root area but not adjacent gray voxels in the CSF-root interface were chosen. RESULTS: Significant differences were found between caudal and rostral thresholds. No significant differences were found between expert and nonexpert observers. Average max/min thresholds were around 1.30 but max/min CSF volumes were around 1.15. Great interindividual CSF volume variability was detected (max/min volumes 1.6-2.7). CONCLUSIONS: The estimation of a close range of CSF volumes which probably contains the real CSF volume value can be standardized and calculated prior to certain intrathecal procedures

Análise de imagem em química analítica: empregando metodologias simples e didáticas para entender e prevenir o escurecimento de tecidos vegetais

A simple and didactic experiment was developed for image monitoring of the browning of fruit tissues caused by the enzyme polyphenol oxidase. The procedure, easy and inexpensive, is a valuable tool to teach and demonstrate the redox reaction between the enzyme and the natural polyphenols. To obtain the browning percentage for apple, pear and banana, digital photographs were employed, and the images were analyzed by means of Monte Carlo methods and digital analysis programs. The effects of several experimental conditions were studied, such as pH, light, temperature and the presence of oxygen or anti-oxidants. It was observed that each fruit presented a different condition that better minimized the oxidation process. The absence of oxygen and the application of a bissulphite solution were sufficient to keep the quality of all fruits tested.

Alternative technique for biodiesel quality control using an optical fiber long-period grating sensor

We report the use of an optical fiber sensor to measure the soybean oil concentration in samples obtained from the mixture of pure biodiesel and commercial soybean oil. The operation of the device is based on the long-period grating sensitivity to the surrounding medium refractive index, which leads to measurable modifications in the grating transmission spectrum. The proposed analysis method results in errors in the oil concentration of 0.4% and 2.6% for pure biodiesel and commercial soybean oil, respectively. Techniques of total glycerol, dynamic viscosity, density, and hydrogen nuclear magnetic resonance spectroscopy were also employed to validate the proposed method.

Programa d'anàlisi d'imatges de provetes metal·logràfiques

L’objectiu del present TFM és explorar les possibilitats del programa matemàtic MATLAB i la seva eina Entorn de Disseny d’Interfícies Gràfiques d’Usuari (GUIDE), desenvolupant un programa d’anàlisi d’imatges de provetes metal·logràfiques que es pugui utilitzar per a realitzar pràctiques de laboratori de l’assignatura Tecnologia de Materials de la titulació de Grau en Enginyeria Mecatrònica que s’imparteix a la Universitat de Vic. Les àrees d’interès del treball són la Instrumentació Virtual, la programació MATLAB i les tècniques d’anàlisi d’imatges metal·logràfiques. En la memòria es posa un èmfasi especial en el disseny de la interfície i dels procediments per a efectuar les mesures. El resultat final és un programa que satisfà tots els requeriments que s’havien imposat en la proposta inicial. La interfície del programa és clara i neta, destinant molt espai a la imatge que s’analitza. L’estructura i disposició dels menús i dels comandaments ajuda a que la utilització del programa sigui fàcil i intuïtiva. El programa s’ha estructurat de manera que sigui fàcilment ampliable amb altres rutines de mesura, o amb l’automatització de les rutines existents. Al tractar-se d’un programa que funciona com un instrument de mesura, es dedica un capítol sencer de la memòria a mostrar el procediment de càlcul dels errors que s’ocasionen durant la seva utilització, amb la finalitat de conèixer el seu ordre de magnitud, i de saber-los calcular de nou en cas que variïn les condicions d’utilització. Pel que fa referència a la programació, malgrat que MATLAB no sigui un entorn de programació clàssic, sí que incorpora eines que permeten fer aplicacions no massa complexes, i orientades bàsicament a gràfics o a imatges. L’eina GUIDE simplifica la realització de la interfície d’usuari, malgrat que presenta problemes per tractar dissenys una mica complexos. Per altra banda, el codi generat per GUIDE no és accessible, cosa que no permet modificar manualment la interfície en aquells casos en els que GUIDE té problemes. Malgrat aquests petits problemes, la potència de càlcul de MATLAB compensa sobradament aquestes deficiències.

Minimization of the experimental workload for the prediction of pollutants propagation in rivers. Mathematical modelling and knowledge re-use

The present thesis in focused on the minimization of experimental efforts for the prediction of pollutant propagation in rivers by mathematical modelling and knowledge re-use. Mathematical modelling is based on the well known advection-dispersion equation, while the knowledge re-use approach employs the methods of case based reasoning, graphical analysis and text mining. The thesis contribution to the pollutant transport research field consists of: (1) analytical and numerical models for pollutant transport prediction; (2) two novel techniques which enable the use of variable parameters along rivers in analytical models; (3) models for the estimation of pollutant transport characteristic parameters (velocity, dispersion coefficient and nutrient transformation rates) as functions of water flow, channel characteristics and/or seasonality; (4) the graphical analysis method to be used for the identification of pollution sources along rivers; (5) a case based reasoning tool for the identification of crucial information related to the pollutant transport modelling; (6) and the application of a software tool for the reuse of information during pollutants transport modelling research. These support tools are applicable in the water quality research field and in practice as well, as they can be involved in multiple activities. The models are capable of predicting pollutant propagation along rivers in case of both ordinary pollution and accidents. They can also be applied for other similar rivers in modelling of pollutant transport in rivers with low availability of experimental data concerning concentration. This is because models for parameter estimation developed in the present thesis enable the calculation of transport characteristic parameters as functions of river hydraulic parameters and/or seasonality. The similarity between rivers is assessed using case based reasoning tools, and additional necessary information can be identified by using the software for the information reuse. Such systems represent support for users and open up possibilities for new modelling methods, monitoring facilities and for better river water quality management tools. They are useful also for the estimation of environmental impact of possible technological changes and can be applied in the pre-design stage or/and in the practical use of processes as well.

The influence of crystallization conditions on the filtration characteristics of sulphathiazole suspensions

Cooling crystallization is one of the most important purification and separation techniques in the chemical and pharmaceutical industry. The product of the cooling crystallization process is always a suspension that contains both the mother liquor and the product crystals, and therefore the first process step following crystallization is usually solid-liquid separation. The properties of the produced crystals, such as their size and shape, can be affected by modifying the conditions during the crystallization process. The filtration characteristics of solid/liquid suspensions, on the other hand, are strongly influenced by the particle properties, as well as the properties of the liquid phase. It is thus obvious that the effect of the changes made to the crystallization parameters can also be seen in the course of the filtration process. Although the relationship between crystallization and filtration is widely recognized, the number of publications where these unit operations have been considered in the same context seems to be surprisingly small. This thesis explores the influence of different crystallization parameters in an unseeded batch cooling crystallization process on the external appearance of the product crystals and on the pressure filtration characteristics of the obtained product suspensions. Crystallization experiments are performed by crystallizing sulphathiazole (C9H9N3O2S2), which is a wellknown antibiotic agent, from different mixtures of water and n-propanol in an unseeded batch crystallizer. The different crystallization parameters that are studied are the composition of the solvent, the cooling rate during the crystallization experiments carried out by using a constant cooling rate throughout the whole batch, the cooling profile, as well as the mixing intensity during the batch. The obtained crystals are characterized by using an automated image analyzer and the crystals are separated from the solvent through constant pressure batch filtration experiments. Separation characteristics of the suspensions are described by means of average specific cake resistance and average filter cake porosity, and the compressibilities of the cakes are also determined. The results show that fairly large differences can be observed between the size and shape of the crystals, and it is also shown experimentally that the changes in the crystal size and shape have a direct impact on the pressure filtration characteristics of the crystal suspensions. The experimental results are utilized to create a procedure that can be used for estimating the filtration characteristics of solid-liquid suspensions according to the particle size and shape data obtained by image analysis. Multilinear partial least squares regression (N-PLS) models are created between the filtration parameters and the particle size and shape data, and the results presented in this thesis show that relatively obvious correlations can be detected with the obtained models.
