Competitors' Financial Performance Monitoring Model

The objective of the thesis was to develop a competitors’ financial performance monitoring model for management reporting. The research consisted of the selections of the comparison group and the performance meters as well as the actual creation of the model. A brief analysis of the current situation was also made. The aim of the results was to improve the financial reporting quality in the case organization by adding external business environment observation to the management reports. The comparison group for the case company was selected to include five companies that were all involved in power equipment engineering and project type business. The most limiting factor related to the comparison group selection was the availability of quarterly financial reporting. The most suitable performance meters were defined to be the developments of revenue, order backlog and EBITDA. These meters should be monitored systematically on quarterly basis and reported to the company management in a brief and informative way. The monitoring model was based on spreadsheet construction with key characteristics being usability, flexibility and simplicity. The model acts as a centered storage for financial competitor information as well as a reporting tool. The current market situation is strongly affected by the economic boom in the recent years and future challenges can be clearly seen in declining order backlogs. The case company has succeeded well related to its comparison group during the observation period since its business volume and profitability have developed in the best way.

WCDMA HSPA performance counters for monitoring 3G-radio access network

The objective of this project was to gather all the counters which are used on HSPA performance monitoring. The main purpose was to create a compact packet of HSPA performance counters and radio network monitoring which Ericsson's employees can then use in their daily work. The study includes a short introduction to the architecture of the 3G-radio access network. The HSPA technology and HSPA performance are presented including a functional description of performance counters and KPIs, which are used for performance management and monitoring. The theory part of the study also covers an overview of performance management in OSS-RC. The final part of the study covers an overview of the performance management tools, in-troducing how the counters are represented in these interfaces. MOShell and OSS-RC are tools used in this study. Tools were selected because the MOShell is Ericsson's inter-nal management tool and OSS-RC is a tool designed for customers.

Using ICT Energy consumption for monitoring ICT architecture

Energy efficient policies are being applied to network protocols, devices and classical network management systems. Researchers have already studied in depth each of those fields, including for instance a long monitoring processes of various number of individual ICT equipment from where power models are constructed. With the development of smart meters and emerging protocols such as SNMP and NETCONF, currently there is an open field to couple the power models, translated to the expected behavior, with the realtime energy measurements. The goal is to derive a comparison on the power data between both of the processes in the direction of detection for possible deviations on the expected results. The logical assumption is that a fault in the usage of a particular device will not only increase its own energy usage, but also may cause additional consumption on the other devices part of the network. A platform is developed to monitor and analyze the retrieved power data of a simulated enterprise ICT infrastructure. Moreover, smart algorithms are developed which are aware of the different states that are occurring on each device during their typical use phase, as well as to detect and isolate possible anomalies. The produced results are obtained and validated with the use of Cisco switches and routers, Dell Precision stations and Raritan PDU as part of the monitored infrastructure.

pH:n stabiilisuus ditioniittivalkaistulla neutraalilla LWC-prosessilla

Tässä työssä Oy Keskuslaboratoriossa sijaitsevalla kiertovesisimulaattorilla on tutkittiu ditioniittivalkaisun ja hylyn määrän vaikutusta pH:n stabiilisuuteen ja häiriöaineiden määrään neutraalissa LWC-prosessissa. Lisäksi on tutkittu ditioniitin määrän seisokkien ja valkaisuviiveiden vaikutusta. Kirjallisuusosassa tutustutaan ditioniittivalkaisuun ja valkaisun kemiaan sekä kalsiumkarbonaatin liukenemiseen. Lyhyesti selvitetään myös paperikoneen vesikiertoja sekä prosessissa olevia häiriöaineita. Karbonaatin liukenemisen osalta tarkastellaan myös mahdollisuutta mallintaa prosessia. Diplomityön aikana ajettiin yhdeksän simulaattoriajoa, jotka ajettiin kahden tai kolmen ajon sarjoissa. Ajoja ajettiin kolmella eri hylkymäärällä. Ditioniittivalkaisun lisäksi suoritettiin referenssiajoja ilman valkaisua. Lyhyen kierron pH pyrittiin pääosin säätämään seitsemään. Valkaisuviiveiden ja yli-yön kestävien seisokkien vaikutusta tutkittiin myös. Kokeissa todettiin ditioniitin alentavan pH tasoa. Tämä pH:n aleneminen johtaa kalsiumkarbonaatin liukenemiseen kalsiumkarbonaatin pyrkiessä puskuroimaan pH:n laskua. Valkaisureaktiossa syntyy negatiivisesti varauruneita yhdisteitä, jotka lisäävät prosessin anionisuutta. Ditioniitin valkaisuvaikutus näkyi lopputuotteen vaaleuden kasvuna sekä kieroveden värillisten yhdisteiden vähenemisenä. Ditioniittivalkaisu näytti poistavan myös noin 30% ligniinistä. Lipofiilisiin uuteaineisiin ditioniitilla ei ollut vaikutusta. Riittävä ditioniittiannos kokeiden perusteella on korkeintaan 1% ditioniittiä käytetyn mekaanisen massan määrästä. Korkeammalla annostuksella ei ollut vaikutusta vaaleuteen. Valkaisuaikana 30 minuuttia on riittävä. Pidempien valkaisuviiveiden ja seisokkien aikana valkaisussa syntyvän sulfiitin todettiin muuttuvan sulfaatiksi. Hylyn määrän lisääminen nosti pH:ta, varausta, johtokykyä ja liuenneen kalsiumin määrään. Hylyn määrän lisäminen paransi myös optisia ominaisuuksia, mikä johtui osin hylyn sisältämästä kalsiumkarbonaatista ja osin hylyn sisältämästä mekaanisesta massasta, joka oli valkaistua.

Laitosmittaukset turbiinilaitoksen suorituskyvyn seurantaan ydinvoimalaitoksen vuosihuoltojen yhteydessä

Työssä kehitettiin höyryvoimalaitosprosessin tilan seurantaan laitosmittausrutiini, jolla tarkastellaan erityisesti turbiinilaitoksen suorituskykyä ennen ja jälkeen vuosihuoltojen. Laitosmittaukset on kehitetty Teollisuuden Voima Oyj:n Olkiluodon ydinvoimalaitosyksikköjen OL1 ja OL2 tarpeisiin. Mittauksilla saadaan tietoa vuosihuollon kokonaisvaikutuksista prosessiin eli muuttuiko mikään vuosihuollon aikana ja mitkä syyt johtivat muutokseen. Lisäksi säännöllisillä mittauksilla tavoitellaan pitkän aikavälin referenssitietoa prosessin tilasta. Esimerkkimittaukset tehtiin kevään 2008 vuosihuolloissa, R108 ja R208. Työssä on esitetty mittausten suorittaminen, tulosten laskenta ja tarkastelu sekä raportointi. Luotu mittausrutiini pohjautuu höyryturbiinien ja lämmönsiirtimien vastaanottokokeita käsitteleviin standardeihin sekä laitosten viimeisimpiin prosessimuutosten yhteydessä toteutettuihin suorituskykymittauksiin. Laitosmittauksista tehtiin vastaanottokokeita kevyemmät ja yksinkertaisemmat mittaustapahtumat, joilla saadaan kuitenkin riittävän luotettavaa tietoa. Tunnuslukuja, joita ei käytettävissä olevien mittatietojen avulla saatu suoraan selville tai laskettua massa- ja energiataseilla, määritettiin stationaarisen tilan mallinnusohjelmalla TEMPO:lla. Esimerkkimittaukset sujuivat hyvin ja saadut tulokset antoivat kaivattua lisätietoa vuosihuollon vaikutuksesta prosessiin. Generaattorin bruttoteho aleni OL1:llä ja pysyi ennallaan OL2:lla. OL1:n tehon aleneminen selittyi syöttöveden virtausmäärän vähenemisellä, johon vaikutti virtausmittalaitteen lähettimen vaihto. OL2:lla ei havaittu turbiiniprosessissa muutoksia, mutta lauhduttimien suorituskyky parani. Lauhduttimien suorituskyvyn paraneminen ilmeni asteisuuksien pienentymisenä, johon vaikuttivat puhdistaminen ja ilmavuotojen väheneminen.

Höyryturbiinin käytönaikaisen suorituskyvyn seuranta

Tässä diplomityössä jatkettiin Loviisan voimalaitoksen höyryturbiinien suorituskyvyn parannuspotentiaalien tutkimusta. Tavoitteena oli kehittää laitoksen höyryturbiinien suorituskyvyn käytönaikaisia on-line-mittauksia. Selvityksessä perehdyttiin norjalaisen IFE:n kehittämään stationääritilan TEMPOohjelmaan( The Thermal Performance Monitoring And Optimisation system), sen käyttöohjeisiin ja toimintaperiaatteisiin. Työssä esiteltiin laajasti tiedon yhteensovittamisen laskentateoriaa, johon TEMPOn toiminta perustuu. Työssä tarkasteltiin turbiinin todellista paisuntaprosessia, koska sen ymmärtäminen on tärkeässä osassa turbiinin suorituskyvyn valvonnassa. Tutkimuksessa esiteltiin myös turbiineille mahdollisia vikoja sekä niiden syntymisprosesseja. Työssä tarkasteltiin TEMPOn sovittamien tulostiedostojen analysointiohjelman toimivuutta havaitsemalla itse aiheutettuja poikkeamia todellisiin mittaustiedostoihin. Analysointiohjelmalla muodostettuja kuvaajia vertailtiin todellisen prosessin ajotilanteen kuvaajiin ja tarkasteltiin, kuinka poikkeamia on mahdollista havaita kuvaajien avulla. TEMPO-ohjelmalle löydettiin tutkimuksen edetessä kehittämisehdotuksia. Näillä muutoksilla ohjelma saadaan mallintamaan Loviisan voimalaitoksen turbiiniprosessia tarkemmin ja tuloksista saadaan hyödyllisempiä.

Suorituskyvyn mittaaminen metsäkoneyrityksissä

Tutkimuksessa selvitettiin kyselytutkimuksella yritysseurannan nykytilaa Koneyrittäjien liiton jäseninä olevissa metsäkoneyrityksissä ja haastateltiin sekä käytiin keskusteluja metsäkonealan asiantuntijoiden kanssa. Työn tuloksena tehtiin ehdotus metsäkoneyrityksille soveltuvan seurantatyökalun tietosisällöstä ja hahmoteltiin työkalun rakenne. Vain 54 prosentilla yrityksistä oli järjestelmällistä yritystoiminnan seurantaa. Yleisin syy seuraamattomuudelle oli ajan puute. Niissä yrityksissä, joilla oli järjestelmällistä seurantaa, talouden tunnusluvuista aktiivisimmin seurattiin liikevoittoa. Puunkorjuuprosessia kuvaavista tunnusluvuista aktiivisimmin seurattiin puunkorjuun tuottavuutta. Ehdotetussa työkalussa rajauduttiin suorituskyvyn taloudelliseen ja prosessinäkökulmaan. Prosessinäkökulmassa keskityttiin puunkorjuuprosessiin ja tutkittiin, kuinka uuden StanForD2010 –tiedonsiirtostandardin avulla puunkorjuun tunnuslukujen tuottaminen voitaisiin automatisoida. Seurantatyökalun sisällöksi ehdotettiin yhteensä 43 talouden ja puun-korjuuprosessin tunnuslukua. Lisäksi ehdotettiin, että yrityksen suorituskykyä kuvaamaan laskettaisiin yrityskohtaisesti valittavista tunnusluvuista johdettu yksi tunnusluku – kokonaissuorituskykyindeksi. Ehdotettu seurantatyökalu mahdollistaa suorituskyvyn mittaamisen tehostamisen metsäkoneyrityksissä. Työkalusta puuttuvat asiakas- ja henkilöstö- sekä oppimisnäkökulmat, joten jatkossa onkin selvitettävä näiden näkökulmien liittäminen työkaluun.

Blue and Uv-Emitting Upconversion Nanoparticles: Synthesis and (Bio) Analytical Applications.

Rare-earth based upconverting nanoparticles (UCNPs) have attracted much attention due to their unique luminescent properties. The ability to convert multiple photons of lower energy to ones with higher energy through an upconversion (UC) process offers a wide range of applications for UCNPs. The emission intensities and wavelengths of UCNPs are important performance characteristics, which determine the appropriate applications. However, insufficient intensities still limit the use of UCNPs; especially the efficient emission of blue and ultraviolet (UV) light via upconversion remains challenging, as these events require three or more near-infrared (NIR) photons. The aim of the study was to enhance the blue and UV upconversion emission intensities of Tm3+ doped NaYF4 nanoparticles and to demonstrate their utility in in vitro diagnostics. As the distance between the sensitizer and the activator significantly affect the energy transfer efficiency, different strategies were explored to change the local symmetry around the doped lanthanides. One important strategy is the intentional co-doping of active (participate in energy transfer) or passive (do not participate in energy transfer) impurities into the host matrix. The roles of doped passive impurities (K+ and Sc3+) in enhancing the blue and UV upconversions, as well as in influencing the intense UV upconversion emission through excess sensitization (active impurity) were studied. Additionally, the effects of both active and passive impurity doping on the morphological and optical performance of UCNPs were investigated. The applicability of UV emitting UCNPs as an internal light source for glucose sensing in a dry chemistry test strip was demonstrated. The measurements were in agreement with the traditional method based on reflectance measurements using an external UV light source. The use of UCNPs in the glucose test strip offers an alternative detection method with advantages such as control signals for minimizing errors and high penetration of the NIR excitation through the blood sample, which gives more freedom for designing the optical setup. In bioimaging, the excitation of the UCNPs in the transparent IR region of the tissue permits measurements, which are free of background fluorescence and have a high signal-to-background ratio. In addition, the narrow emission bandwidth of the UCNPs enables multiplexed detections. An array-in-well immunoassay was developed using two different UC emission colours. The differentiation between different viral infections and the classification of antibody responses were achieved based on both the position and colour of the signal. The study demonstrates the potential of spectral and spatial multiplexing in the imaging based array-in-well assays.

Practical Framework for Monitoring the Performance of Agile IT Projects in an Output-Based Outsourcing Context

Over the past decade, organizations worldwide have begun to widely adopt agile software development practices, which offer greater flexibility to frequently changing business requirements, better cost effectiveness due to minimization of waste, faster time-to-market, and closer collaboration between business and IT. At the same time, IT services are continuing to be increasingly outsourced to third parties providing the organizations with the ability to focus on their core capabilities as well as to take advantage of better demand scalability, access to specialized skills, and cost benefits. An output-based pricing model, where the customers pay directly for the functionality that was delivered rather than the effort spent, is quickly becoming a new trend in IT outsourcing allowing to transfer the risk away from the customer while at the same time offering much better incentives for the supplier to optimize processes and improve efficiency, and consequently producing a true win-win outcome. Despite the widespread adoption of both agile practices and output-based outsourcing, there is little formal research available on how the two can be effectively combined in practice. Moreover, little practical guidance exists on how companies can measure the performance of their agile projects, which are being delivered in an output-based outsourced environment. This research attempted to shed light on this issue by developing a practical project monitoring framework which may be readily applied by organizations to monitor the performance of agile projects in an output-based outsourcing context, thus taking advantage of the combined benefits of such an arrangement Modified from action research approach, this research was divided into two cycles, each consisting of the Identification, Analysis, Verification, and Conclusion phases. During Cycle 1, a list of six Key Performance Indicators (KPIs) was proposed and accepted by the professionals in the studied multinational organization, which formed the core of the proposed framework and answered the first research sub-question of what needs to be measured. In Cycle 2, a more in-depth analysis was provided for each of the suggested Key Performance Indicators including the techniques for capturing, calculating, and evaluating the information provided by each KPI. In the course of Cycle 2, the second research sub-question was answered, clarifying how the data for each KPI needed to be measured, interpreted, and acted upon. Consequently, after two incremental research cycles, the primary research question was answered describing the practical framework that may be used for monitoring the performance of agile IT projects delivered in an output-based outsourcing context. This framework was evaluated by the professionals within the context of the studied organization and received positive feedback across all four evaluation criteria set forth in this research, including the low overhead of data collection, high value of provided information, ease of understandability of the metric dashboard, and high generalizability of the proposed framework.

Flexible Sensor for Wearable Vital Sign Monitoring System

In modern society, the body health is a very important issue to everyone. With the development of the science and technology, the new and developed body health monitoring device and technology will play the key role in the daily medical activities. This paper focus on making progress in the design of the wearable vital sign system. A vital sign monitoring system has been proposed and designed. The whole detection system is composed of signal collecting subsystem, signal processing subsystem, short-range wireless communication subsystem and user interface subsystem. The signal collecting subsystem is composed of light source and photo diode, after emiting light of two different wavelength, the photo diode collects the light signal reflected by human body tissue. The signal processing subsystem is based on the analog front end AFE4490 and peripheral circuits, the collected analog signal would be filtered and converted into digital signal in this stage. After a series of processing, the signal would be transmitted to the short-range wireless communication subsystem through SPI, this subsystem is mainly based on Bluetooth 4.0 protocol and ultra-low power System on Chip(SoC) nRF51822. Finally, the signal would be transmitted to the user end. After proposing and building the system, this paper focus on the research of the key component in the system, that is, the photo detector. Based on the study of the perovskite materials, a low temperature processed photo detector has been proposed, designed and researched. The device is made up of light absorbing layer, electron transporting and hole blocking layer, hole transporting and electron blocking layer, conductive substrate layer and metal electrode layer. The light absorbing layer is the important part of whole device, and it is fabricated by perovskite materials. After accepting the light, the electron-hole pair would be produced in this layer, and due to the energy level difference, the electron and hole produced would be transmitted to metal electrode and conductive substrate electrode through electron transporting layer and hole transporting layer respectively. In this way the response current would be produced. Based on this structure, the specific fabrication procedure including substrate cleaning; PEDOT:PSS layer preparation; pervoskite layer preparation; PCBM layer preparation; C60, BCP, and Ag electrode layer preparation. After the device fabrication, a series of morphological characterization and performance testing has been done. The testing procedure including film-forming quality inspection, response current and light wavelength analysis, linearity and response time and other optical and electrical properties testing. The testing result shows that the membrane has been fabricated uniformly; the device can produce obvious response current to the incident light with the wavelength from 350nm to 800nm, and the response current could be changed along with the light wavelength. When the light wavelength keeps constant, there exists a good linear relationship between the intensity of the response current and the power of the incident light, based on which the device could be used as the photo detector to collect the light information. During the changing period of the light signal, the response time of the device is several microseconds, which is acceptable working as a photo detector in our system. The testing results show that the device has good electronic and optical properties, and the fabrication procedure is also repeatable, the properties of the devices has good uniformity, which illustrates the fabrication method and procedure could be used to build the photo detector in our wearable system. Based on a series of testing results, the paper has drawn the conclusion that the photo detector fabricated could be integrated on the flexible substrate and is also suitable for the monitoring system proposed, thus made some progress on the research of the wearable monitoring system and device. Finally, some future prospect in system design aspect and device design and fabrication aspect are proposed.

On the Condition Monitoring of Induction machines

The research of condition monitoring of electric motors has been wide for several decades. The research and development at universities and in industry has provided means for the predictive condition monitoring. Many different devices and systems are developed and are widely used in industry, transportation and in civil engineering. In addition, many methods are developed and reported in scientific arenas in order to improve existing methods for the automatic analysis of faults. The methods, however, are not widely used as a part of condition monitoring systems. The main reasons are, firstly, that many methods are presented in scientific papers but their performance in different conditions is not evaluated, secondly, the methods include parameters that are so case specific that the implementation of a systemusing such methods would be far from straightforward. In this thesis, some of these methods are evaluated theoretically and tested with simulations and with a drive in a laboratory. A new automatic analysis method for the bearing fault detection is introduced. In the first part of this work the generation of the bearing fault originating signal is explained and its influence into the stator current is concerned with qualitative and quantitative estimation. The verification of the feasibility of the stator current measurement as a bearing fault indicatoris experimentally tested with the running 15 kW induction motor. The second part of this work concentrates on the bearing fault analysis using the vibration measurement signal. The performance of the micromachined silicon accelerometer chip in conjunction with the envelope spectrum analysis of the cyclic bearing faultis experimentally tested. Furthermore, different methods for the creation of feature extractors for the bearing fault classification are researched and an automatic fault classifier using multivariate statistical discrimination and fuzzy logic is introduced. It is often important that the on-line condition monitoring system is integrated with the industrial communications infrastructure. Two types of a sensor solutions are tested in the thesis: the first one is a sensor withcalculation capacity for example for the production of the envelope spectra; the other one can collect the measurement data in memory and another device can read the data via field bus. The data communications requirements highly depend onthe type of the sensor solution selected. If the data is already analysed in the sensor the data communications are needed only for the results but in the other case, all measurement data need to be transferred. The complexity of the classification method can be great if the data is analysed at the management level computer, but if the analysis is made in sensor itself, the analyses must be simple due to the restricted calculation and memory capacity.

Container Handling Equipment Monitoring System, case: Steveco Oy

Container Handling Equipment Monitoring System (CHEMS) is a system developed by Savcor One Oy. CHEMS measures important information for container ports performance and produces performance indicators. The aim of this thesis was to clarify performance measurement contents to Savcor and to develop, as an example, performance measures to Steveco Oy's container operations. The theoretical part of the thesis clarifies performance measurement and which of its components are important to container port. Performance measurement and measures are presented from the operational level's point of view, in which CHEMS is planned to aim. The theory of development process of performance measures is introduced at the end of the theoretical part. To make sure that performance measures are efficiently used, Steveco Oy's performance measures are developed in cooperation with the users. The measurement in operational level is continuous and the results must be reacted asquickly as possible. CHEMS is very suitable to continuous measurement and to produce real time-measures of container operations which are hard to get any otherway.

Deep-hole drilling process, monitoring system and sensors modifications

 In the drilling processes and especially deep-hole drilling process, the monitoring system and having control on mechanical parameters (e.g. Force, Torque,Vibration and Acoustic emission) are essential. The main focus of this thesis work is to study the characteristics of deep-hole drilling process, and optimize the monitoring system for controlling the process. The vibration is considered as a major defect area of the deep-hole drilling process which often leads to breakage of the drill, therefore by vibration analysis and optimizing the workpiecefixture, this area is studied by finite element method and the suggestions are explained. By study on a present monitoring system, and searching on the new sensor products, the modifications and recommendations are suggested for optimize the present monitoring system for excellent performance in deep-hole drilling process research and measurements.

Performance Evaluation of Imaging Systems

Imaging systems have developed latest years and developing is still continuing following years. Manufacturers of imaging systems give promises for the quality of the performance of imaging systems to advertise their products. Promises for the quality of the performance are often so good that they will not be tested in normal usage. The main target in this research is to evaluate the quality of the performance of two imaging systems: Scanner and CCD color camera. Optical measurement procedures were planned to evaluate the quality of imaging performances. Other target in this research is to evaluate calibration programs for the camera and the scanner. Measuring targets had to choose to evaluate the quality of imaging performances. Manufacturers have given definitions for targets. The third task in this research is to evaluate and consider how good measuring targets are.
