FLASH-OFDM System Performance Studies for Wireless Broadband Network Operator Services

@450 wireless broadband service is Digita’s mobile wireless broadband network service. In @450 network Digita acts as the network operator offering network capacity to service operators. For Digita it is important to know what kind of services its network is capable of and what are the network’s service parameters. The knowledge of the network parameters and the behaviour can be used in advance in the development of new service products. Before a new service product can be offered to service operators a lot of work has to be done. The basic testing is necessary to get an understanding of the basic functionality. The requirement specification has to be done and a new product has to be created. The new product has to be tested. The test results have to be analysed in order to find out if the new product is suitable for real use and with which limitations. The content of this Thesis is the development of wireless technologies, @450 service and network, FLASH-OFDM technology, FLASH-OFDM performance testing and the development of a new service product.

Evaluation of energy efficiency and best available techniques in pumping processes

The potential for enhancing the energy efficiency of industrial pumping processes is estimated to be in some cases up to 50 %. One way to define further this potential is to implement techniques in accordance to definition of best available techniques in pumping applications. These techniques are divided into three main categories: Design, control method & maintenance and distribution system. In the theory part of this thesis first the definition of best available techniques (BAT) and its applicability on pumping processes is issued. Next, the theory around pumping with different pump types is handled, the main stress being in centrifugal pumps. Other components needed in a pumping process are dealt by presenting different control methods, use of an electric motor, variable speed drive and the distribution system. Last part of the theory is about industrial pumping processes from water distribution, sewage water and power plant applications, some of which are used further on in the empirical part as example cases. For the empirical part of this study four case studies on typical pumping processes from older Master’s these were selected. Firstly the original results were analyzed by studying the distribution of energy consumption between different system components and using the definition of BAT in pumping, possible ways to improve energy efficiency were evaluated. The goal in this study was that by the achieved results it would be possible to identify the characteristic energy consumption of these and similar pumping processes. Through this data it would then be easier to focus energy efficiency actions where they might be the most applicable, both technically and economically.

Indicent reporting in shipping. Experiences and best practices for the Baltic Sea

Incident and near miss reporting is one of the proactive tools of safety management. By analyzing incidents and near misses and by corrective actions, severe accidents can potentially be avoided. Near miss and incident reporting is widely used in many riskprone industries such as aviation or chemical industry. In shipping incident and near miss reporting is required by the mandatory safety management system International Safety Management Code (ISM Code). However, in several studies the conclusion has been that incidents are reported poorly in the shipping industry. The aim of this report is to highlight the best practices for incident reporting in shipping and to support the shipping industry in the better utilization of incident reporting information. The study consists of three parts: 1) voluntary, shared reporting systems in shipping (international experiences), 2) interview study at four shipping companies in Sweden and in Finland (best practices), 3) expert workshop on incident reporting (problems and solutions). Preconditions for a functional reporting system are an existing no blame culture, commitment of the top management, feedback, good communication, training and an easy-to-use system. Although preconditions are met, problems can still appear, for example due to psychological, interpersonal or nationality-related reasons. In order to keep the reporting system functioning, the shipping company must be committed to maintain and develop the system and to tackle the problems. The whole reporting process from compiling, handling and analyzing a report, creating corrective actions and implementing them has to be handled properly in order to gain benefits from the reporting system. In addition to avoiding accidents, the functional reporting system can also offer other benefits by increasing safety awareness, by improving the overall safety and working conditions onboard, by enhancing team work and communication onboard and between ships and the land-based organization of shipping companies. Voluntary shared reporting systems are supported in the shipping industry in principle, but their development in the Baltic Sea is still in its infancy and the potential benefits of sharing the reports have not been realized. On the basis of this study we recommend that a common reporting system be developed for the Baltic Sea area which all the ships operating in the area could use regardless of their flag. Such a wider system could prevent some of the problems related to the current national systems. There would be more incident cases available in the database and this would support anonymity and thus encourage shipping companies to report to a shared database more frequently. A shared reporting system would contribute to the sharing of experiences and to the wider use of incident information in the shipping industry.

Pulmonar recruitment in acute respiratory distress syndrome. What is the best strategy?

Supporting patients with acute respiratory distress syndrome (ARDS), using a protective mechanical ventilation strategy characterized by low tidal volume and limitation of positive end-expiratory pressure (PEEP) is a standard practice in the intensive care unit. However, these strategies can promote lung de-recruitment, leading to the cyclic closing and reopening of collapsed alveoli and small airways. Recruitment maneuvers (RM) can be used to augment other methods, like positive end-expiratory pressure and positioning, to improve aerated lung volume. Clinical practice varies widely, and the optimal method and patient selection for recruitment maneuvers have not been determined, considerable uncertainty remaining regarding the appropriateness of RM. This review aims to discuss recent findings about the available types of RM, and compare the effectiveness, indications and adverse effects among them, as well as their impact on morbidity and mortality in ARDS patients. Recent developments include experimental and clinical evidence that a stepwise extended recruitment maneuver may cause an improvement in aerated lung volume and decrease the biological impact seen with the traditionally used sustained inflation, with less adverse effects. Prone positioning can reduce mortality in severe ARDS patients and may be an useful adjunct to recruitment maneuvers and advanced ventilatory strategies, such noisy ventilation and BIVENT, which have been useful in providing lung recruitment.

ESTABLISH & DEPLOY DOWNSTREAM MARKETING CAPABILITIES: a case study research following the framework implementation journey

According to many academic researches, the development of marketing capabilities can enhance organizational performance. Similarly, downstream marketing capabilities have an important role in accomplishment the organizational goals. Particularly the downstream marketing capabilities identified in this research are the Marketing Communication, Selling, Marketing implementation, and Market information management. These four capabilities are summarized under the following abilities. First, the ability to manage customers’ opinion regarding the offered value from the organization. Second, the ability of the organization to obtain orders from new and established customers. Third, the ability of aligning and translate the marketing strategy into an operating action plan along with the deployment of the organizational resources. Forth, the continuous process of gathering and managing information about the markets. Moreover, the literature review of this research shed light on the elements that compose the downstream marketing capabilities. Specifically, this research examined the downstream processes and the required information required to control these processes based on the American Productivity and Quality Center’s Process Classification Framework. Furthermore, the literature review examined some of the technological tools that are used in marketing processes, and also some managerial implication regarding the management of the downstream marketing employees. Along with the investigation of downstream marketing capabilities, the literature review investigated the utilization and the benefits of Component Business Model and Process Classification Framework, as they are defined by the organizations that developed them. Besides this initial study, the research presents how the examined organization is using the two frameworks together by cross-referring them. Finally, the research presents the optimal deployment of the collected downstream capabilities elements in the current organizational structure. The optimal deployment has been grounded on the information collected from the literature review but also from internal documentation, provided from the examined organization. By comparing the optimal deployment and the current condition on the organization, the research exhibits some points for improvement, but also some of the projects that are currently in progress inside the organization and eventually will provide solutions to these downsides.

Paperitehtaan arkittamon kokonaistehokkuuden nostaminen kunnossapitoa kehittämällä

Tämän diplomityön tavoitteena oli tutkia, miten UPM:n Kymin tehtaan A4- arkittamon kunnossapitotoimintaa pystyttäisiin kehittämään niin, että tuotantolaitoksen kokonaistehokkuutta saataisiin kasvatettua. Työssä on pohdittu keinoja nykyisen, pääasiallisesti korjaavan kunnossapitotoiminnan muuttamiseksi suunnitelmalliseksi eri teorialähtökohtien pohjalta. Keskeinen teoria, johon työn tulokset pohjautuvat, on kokonaisvaltainen tuottava kunnossapito (TPM). Kirjallisuuslähteisiin tukeutuvaa tutkimusta täydensivät useat haastattelut, A4-valmistajille suunnattu laitteiden kuntokartoituskysely ja tuotannon- ja toiminnanohjausjärjestelmistä kerätty mittausaineisto. Työn merkittävimmät tulokset osoittavat, että A4-arkittamon kunnossapitotoimintaa tulisi suunnata nykyistä enemmän käyttökunnossapitolähtöiseksi. Käyttökunnossapito perustuu tuotannon operaattoreiden osallistumiseen kunnossapitotoimiin varsinaisen kunnossapitohenkilöstön ohella. Tuotantooperaattoreilla on työnsä vuoksi parhaat mahdollisuudet käyttämiensä laitteiden kunnonvalvontaan ja näin ollen mahdollisten vikaantumisten ennakointiin jo varhaisessa vaiheessa. Ennakoimalla pystyttäisiin parantamaan kunnossapidon suunnitelmallisuutta, minkä ansiosta laitteiden käytettävyys ja sitä kautta tuotantolaitoksen kokonaistehokkuus olisivat nykyistä korkeampia.

Kuljetusvirtojen yhdistely kannattavaksi kuljetussuoritteeksi maatalouteen liittyvissä tuoteryhmissä

Diplomityön tavoitteena on arvioida kuljetusvirtojen yhdistämisen kannattavuutta. Kannattavuuden arvioimiseksi määritetään kuljetusvirtojen yhdistämisestä syntyneiden kuljetusreittien hinnat, jotka perustuvat reitillä käytettävien ajoneuvojen kuljetuskustannuksiin. Työssä kuvataan reitin hinnan määrittämiseksi rakennetun hinnoittelutyökalun ominaisuuksia ja käyttöä. Kova kilpailu ja huomattava kuljetuskustannusten osuus kaikista logistiikkakustannuksista haastavat yritykset kehittämään toimituspalveluistaan yhä tehokkaampia. Jotta niin asiakkaiden, toimittajien kuin kuljetusyritystenkin tarpeet voidaan mahdollisimman hyvin huomioida, on ensisijaisesti tarkasteltava yrityksen omaa toimintaa ja sen kehittymisvalmiuksia kuljetusten hallinnassa. Kuljetuskustannusten muodostumisen havainnollistamiseksi työssä perehdytään raskaan kuljetuskaluston kustannuslaskelmiin eri tekijöineen. Perusteluja kuljetusten yhdistämisen kannattavuudelle haetaan yritysmaailmassa jo toteutetuista esimerkeistä ja kuljetusten yhdistämisen rajoituksista. Kuljetusvirtojen yhdistelyn avulla yrityksen on mahdollista tehostaa logistisia palveluitaan kuljetusten osalta. Taulukkolaskentapohjainen työkalu auttaa tyhjänä ajettavien reittiosuuksien minimoinnissa. Tyhjänä ajon vähentymisen vaikutus näkyy kuljetuskustannusten alenemisena, jonka hyötyjä voidaan pitkällä aikavälillä jakaa useamman sidosryhmän kesken.
