Costs and Benefits of a Shared Digital Long-Term Preservation System

This paper describes the cost-benefit analysis of digital long-term preservation (LTP) that was carried out in the context of the Finnish National Digital Library Project (NDL) in 2010. The analysis was based on the assumption that as many as 200 archives, libraries, and museums will share an LTP system. The term ‘system’ shall be understood as encompassing not only information technology, but also human resources, organizational structures, policies and funding mechanisms. The cost analysis shows that an LTP system will incur, over the first 12 years, cumulative costs of €42 million, i.e. an average of €3.5 million per annum. Human resources and investments in information technology are the major cost factors. After the initial stages, the analysis predicts annual costs of circa €4 million. The analysis compared scenarios with and without a shared LTP system. The results indicate that a shared system will have remarkable benefits. At the development and implementation stages, a shared system shows an advantage of €30 million against the alternative scenario consisting of five independent LTP solutions. During the later stages, the advantage is estimated at €10 million per annum. The cumulative cost benefit over the first 12 years would amount to circa €100 million.

Energiapuun haketuksen ja murskauksen kustannukset

Energiapuun tuotannossa puu on hienonnettava kuljettimille ja kattilaan sopivaan kokoon. Tämä tehdään Suomessa yleensä joko metsätien varressa välivarastolla, keskitetyssä terminaalissa tai voimalaitoksella. Puu hienonnetaan joko terävillä terillä hakettamalla tai tylpemmillä työkaluilla murskaamalla. Hakkeessa on vähemmän käsittelyä haittaavia pitkiä tikkuja ja sen valmistamiseen tarvittava energia on hiukan pienempi kuin murskaimilla. Viimeksi mainitulla on merkitystä lähinnä karsittua puuta haketettaessa. Murskain puolestaan sallii enemmän epäpuhtauksia raaka-aineessa, joten esimerkiksi kantoja käsitellään vain murskaimilla. Tässä tarkastellaan erityisesti pienpuun haketuksen ja murskauksen kustannuksia. Pienpuuta saadaan nuoren metsän kunnostuksista ja ensiharvennuksista. Se voi olla joko karsimatonta kokopuuta tai karsittua rankaa. Kokonaiskustannukset pienpuun haketukselle tai murskaukselle ovat tämän tutkimuksen mukaan välivarastolla noin 3,4 euroa/MWh ja terminaalilla tai voimalaitoksella noin 2 euroa/MWh. Pääomakustannukset ovat pienpuulla tavallisesti 1-1,2 euroa/MWh, keskitetyllä terminaalilla toimittaessa noin kolmanneksen vähemmän, jos pääomalle asetetaan 10% tuottovaatimus. Työvoimakustannukset ovat 30-80 snt/MWh varaston ja laitteen koosta riippuen, käyttöenergia dieselmoottoria käytettäessä noin 50 snt/MWh, sähkömoottorilla noin 30 snt/MWh. Muut kulut, mm. huolto, ovat yhteensä 40-80 snt/MWh. Energiapuun hankinnan kokonaiskustannuksista raaka-aineen hienontamisen osuus on 10-30% puutavaran lajista ja käytetystä työmenetelmästä riippuen. Terminaaleilla ja voimalaitoksilla toimittaessa on usein kiinnitettävä huomiota melun- ja pölyntorjuntaan. Muun muassa näistä syistä saattaa kiinteä, sähkökäyttöinen murska olla sopiva sellaisiin kohteisiin, joissa käsiteltävät määrät ovat suuria ja toiminta pysyvää. Melun ja pölyn kunnollinen torjunta vaatii suuria rakenteita, joita on vaikea yhdistää liikuteltaviin laitteisiin.

ABOVEGROUND AND BELOWGROUND BIOMASS AND CARBON ESTIMATES FOR CLONAL EUCALYPTUS TREES IN SOUTHEAST BRAZIL

Eucalyptus plantations represent a short term and cost efficient alternative for sequestrating carbon dioxide from the atmosphere. Despite the known potential of forest plantations of fast growing species to store carbon in the biomass, there are relatively few studies including precise estimates of the amount of carbon in these plantations. In this study it was determined the carbon content in the stems, branches, leaves and roots of a clonal Eucalyptus grandis plantation in the Southeast of Brazil. We developed allometric equations to estimate the total amount of carbon and total biomass, and produced an estimate of the carbon stock in the stand level. Altogether, 23 sample trees were selected for aboveground biomass assessment. The roots of 9 of the 23 sampled trees were partially excavated to assess the belowground biomass at a singletree level. Two models with DBH, H and DBH2H were tested. The average relative share of carbon content in the stem, branch, leaf and root compartments was 44.6%, 43.0%, 46.1% and 37.8%, respectively, which is smaller than the generic value commonly used (50%). The best-fit allometric equations to estimate the total amount of carbon and total biomass had DBH2H as independent variable. The root-to-shoot ratio was relatively stable (C.V. = 27.5%) probably because the sub-sample was composed of clones. Total stand carbon stock in the Eucalyptus plantation was estimated to be 73.38 MgC ha-1, which is within the carbon stock range for Eucalyptus plantations.

Measuring Cost of Poor Quality in Industrial Electronics

Quality is not only free but it can be a profit maker. Every dollar that is not spent on doing things wrong becomes a dollar right on the bottom line. The main objective of this thesis is to give an answer on how cost of poor quality can be measured theoretically correctly. Different calculation methods for cost of poor quality are presented and discussed in order to give comprehensive picture about measurement process. The second objective is to utilize the knowledge from the literature review and to apply it when creating a method for measuring cost of poor quality in supplier performance rating. Literature review indicates that P-A-F model together with ABC methodology provides a mean for quality cost calculations. These models give an answer what should be measured and how this measurement should be carried out. However, when product or service quality costs are incurred when quality character derivates from target value, then QLF seems to be most appropriate methodology for quality cost calculation. These methodologies were applied when creating a quality cost calculation method for supplier performance ratings.

A decision support system for cost determination in grain storage facility operations

Many research works have being carried out on analyzing grain storage facility costs; however a few of them had taken into account the analysis of factors associated to all pre-processing and storage steps. The objective of this work was to develop a decision support system for determining the grain storage facility costs and utilization fees in grain storage facilities. The data of a CONAB storage facility located in Ponta Grossa - PR, Brazil, was used as input of the system developed to analyze its specific characteristics, such as amount of product received and stored throughout the year, hourly capacity of drying, cleaning, and receiving, and dispatch. By applying the decision support system, it was observed that the reception and expedition costs were exponentially reduced as the turnover rate of the storage increased. The cleaning and drying costs increased linearly with grain initial moisture. The storage cost increased exponentially as the occupancy rate of the storage facility decreased.

Low cost driver device for microclimate maintenance in the pre-milking of dairy cattle

Due to the importance of the environment on animal production and thus environmental control, the study aims to build a system for monitoring and control the meteorological variables, temperature and relative humidity, low cost, which can be associated with an evaporative cooling system (ECS). The system development included all the stages of assembly, test and laboratory calibration, and later the validation of the equipment carried in the field. The validation step showed results which allowed concluding that the system can be safely used in the monitoring of these variables. The controller was efficient in management of the microclimate in the waiting corral and allowed the maintenance of the air temperature within the comfort range for dairy cattle in pre-milking with averaged 25.09 ºC during the afternoon. The equipment showed the lower cost (R$ 325.76) when compared to other middle market (R$ 450.00).

Generic Life Cycle Cost Model and Cost-effective Solutions

Life cycle costing (LCC) practices are spreading from military and construction sectors to wider area of industries. Suppliers as well as customers are demanding comprehensive cost knowledge that includes all relevant cost elements through the life cycle of products. The problem of total cost visibility is being acknowledged and the performance of suppliers is evaluated not just by low acquisition costs of their products, but by total value provided through the life time of their offerings. The main purpose of this thesis is to provide better understanding of product cost structure to the case company. Moreover, comprehensive theoretical body serves as a guideline or methodology for further LCC process. Research includes the constructive analysis of LCC related concepts and features as well as overview of life cycle support services in manufacturing industry. The case study aims to review the existing LCC practices within the case company and provide suggestions for improvements. It includes identification of most relevant life cycle cost elements, development of cost breakdown structure and generic cost model for data collection. Moreover, certain cost-effective suggestions are provided as well. This research should support decision making processes, assessment of economic viability of products, financial planning, sales and other processes within the case company.

Development of Cost Estimation with Feedback Information in EPCM Business

Target company of this study is a large machinery company, which is, inter alia, engaged in energy and pulp engineering, procurement and construction management (EPCM) supply business. The main objective of this study was to develop cost estimation of the target company by providing more accurate, reliable and up-to-date information through enterprise resource planning (ERP) system. Another objective was to find cost-effective methods to collect total cost of ownership information to support more informed supplier selection decision making. This study is primarily action-oriented, but also constructive, and it can be divided in two sections: theoretical literature review and empirical study on the abovementioned part of the target company’s business. Development of information collection is, in addition to literature review, based on nearly 30 qualitative interviews of employees at various organizational units, functions and levels at the target company. At the core of development was to make initial data more accurate, reliable and available, a necessary prerequisite for informed use of the information. Certain development suggestions and paths were presented in order to regain confidence in ERP system as information source by reorganizing work breakdown structure and by complementing mere cost information with quantitative, technical and scope information. Several methods to use the information ever more effectively were also discussed. While implementation of the development suggestions outreached the scope of this study, it was forwarded in test environment and interest groups.

SOCIAL MEDIA IN INTERNATIONAL BRAND COMMUNICATION OF SMES - A multiple case study of small Finnish design-intensive companies

Social media is a rather new phenomenon which has revolutionised the world of online communication. However, academic research on how companies can benefit from social media is lacking. The research objective of this thesis was to examine the use of social media in international brand communication of small Finnish design-intensive companies. Therefore, this research contributes also to the research gap in SME branding. The focus was on communication targeted at consumers. The research was carried out as a mixed methods research employing the questionnaire and multiple case study methods. The questionnaire was used to gather preliminary information on Finnish design-intensive companies and to provide an eligible list of companies for deeper examination. Then, four case companies were studied in more depth. The empirical evidence of the case companies was mainly gathered through theme interviews. The results of the questionnaire shed light on the internationalisation of small Finnish designintensive companies. On average, the companies had internationalised rather quickly after they had been founded. However, the share of exports was rather low in most of the companies. The results revealed also that social media was already used widely in the exporting companies and the use can be expected to grow in future. The findings of the multiple case study suggest that branding activities in small Finnish designintensive companies are constrained by limited resources and skills. In addition, the branding activities are strongly guided by the vision and values of the entrepreneur(s) rather than extensive marketing research. The brand structure was simple in all case companies and they aimed at having a standardised brand image across markets. However, all case companies had faced a need for some adaptation of their international brand communication. Internationally important brand communication channels were international fairs, the internet, word-of-mouth and social media. Social media offered a cost-effective brand communication channel for the case companies. It was used for various purposes, such as creating brand awareness and affecting how the brand is perceived. The entrepreneurs found the use of social media to be rather easy and the case companies had not faced any major challenges. However, the companies had recognised that communication in social media requires consistency and planning. The planning was rather informal and stayed on a general level. Overall, the utilisation of social media in the case companies was limited by a lack of resources. It seemed to affect especially the follow-up of brand communication in social media which stayed rather superficial.

Biopolttoaineen rinnakkaispolton kannattavuustarkastelu hiilipölypolttokattilassa Martinlaakso 2:ssa

Euroopan unionin asettamat tavoitteet kasvihuonepäästöjen vähennykselle johtavat vih-reämpään teknologiaan. Tämä diplomityö on teoreettinen tutkimus, joka käsittelee biopolt-toaineen rinnakkaispolton kannattavuutta Vantaan Energian Martinlaakso 2:sen hiilipöly-polttokattilassa. Työssä perehdytään viiteen eri biopolttoainevaihtoehtoon, joita tarkastellaan viidessä eri skenaariossa, jotka vastaavat: 10, 20, 30, 40 ja 50 % biopolttoaineen osuutta kattilassa tuo-tetusta energiasta. Skenaarioissa on pohdittu tarvittavia investointikustannuksia ja muutos-töitä hiilipölypolttokattilassa. Tutkimuksessa on huomioitu myös uusi isojen laitosten pääs-töjä koskeva direktiivi, kattilan oletettava käyttöikä sekä biopolttoaineiden tuet. Saaduista arvioista on lopuksi laskettu vuosittainen polttoainekohtainen kustannusarvio ja investoin-nin kannattavuusarvio. Tuloksista voidaan päätellä, että sahanpurun mahdollisimman suuri hyötykäyttö on kannat-tavaa. Mikäli halutaan käyttää suuria määriä biopolttoainetta, (yli 20 % tuotetusta energias-ta) ei sahanpuru ole varteenotettava vaihtoehto huonon saatavuutensa johdosta. Tällöin hakkeen kaasutuslaitos olisi paras ratkaisu, mutta laitoksen kannattavuus riippuu tulevista energiatuista. Ilman energiatukia sahanpurun hyötykäyttö on ainoa kannattava investointi.
