Airports have become platforms that derive revenues from both aeronautical and commercial activities. The demand for these services is characterized by a one-way complementarity in that only air travelers can purchase retail goods at the airport terminals. We analyze a model of optimal airport behavior in which this one-way complementarity is subject to consumer foresight, i.e., consumers may not anticipate in full the ex post retail surplus when purchasing a flight ticket. An airport sets landing fees, and, in addition, also chooses the retail market structure by selecting the number of retail concessions to be awarded. We find that, with perfectly myopic consumers, the airport chooses to attract more passengers via low landing fees, and also sets the minimum possible number of retailers in order to increase the concessions’ revenues, from which it obtains the largest share of profits. However, even a very small amount of anticipation of the consumer surplus from retail activities changes significantly the airport’s choices: the optimal airport policy is dependent on the degree of differentiation in the retail market. When consumers instead have perfect foresight, the airport establishes a very competitive retail market, where consumers enjoy a large surplus. This attracts passengers and it is exploited by the airport by charging higher landing fees, which then constitute the largest share of its profits. Overall, the airport’s profits are maximal when consumers have perfect foresight. Keywords: two-sided markets, platform pricing, one-way demand complementarity, consumer foresight. JEL classification: L1, L2, L93.

We have designed and validated a novel generic platform for production of tetravalent IgG1-like chimeric bispecific Abs. The VH-CH1-hinge domains of mAb2 are fused through a peptidic linker to the N terminus of mAb1 H chain, and paired mutations at the CH1-CL interface mAb1 are introduced that force the correct pairing of the two different free L chains. Two different sets of these CH1-CL interface mutations, called CR3 and MUT4, were designed and tested, and prototypic bispecific Abs directed against CD5 and HLA-DR were produced (CD5xDR). Two different hinge sequences between mAb1 and mAb2 were also tested in the CD5xDR-CR3 or -MUT4 background, leading to bispecific Ab (BsAbs) with a more rigid or flexible structure. All four Abs produced bound with good specificity and affinity to CD5 and HLA-DR present either on the same target or on different cells. Indeed, the BsAbs were able to efficiently redirect killing of HLA-DR(+) leukemic cells by human CD5(+) cytokine-induced killer T cells. Finally, all BsAbs had a functional Fc, as shown by their capacity to activate human complement and NK cells and to mediate phagocytosis. CD5xDR-CR3 was chosen as the best format because it had overall the highest functional activity and was very stable in vitro in both neutral buffer and in serum. In vivo, CD5xDR-CR3 was shown to have significant therapeutic activity in a xenograft model of human leukemia.

Tehokkaasti toimiva sähköinen tiedonvälitys yrityksen omien sovellusten välillä sekä sen liikekumppaneiden kanssa on kasvanut merkittäväksi yrityksen kilpailukykyä lisääväksi tekijäksi. Yritysten erilaiset tietojärjestelmät asettavat haasteita tehokkaalle tiedonvälitykselle näiden järjestelmien välillä. Perinteiset EDI teknologioihin perustuvat sähköisen tiedonvälityksen ratkaisut eivät pysty mukautumaan nykyisin nopeasti muuttuviin markkinatilanteisiin. Palvelukeskeiseen arkkitehtuuriin ja Web-palveluihin perustuvat teknologiat mahdollistavat mukautumisen erilaisiin muutoksiin liiketoiminnassa nopeammin ja helpommin. Lisäksi ne nopeuttavat tiedon integrointia erilaisten tietojärjestelmien välillä, koska tiedonvälityksessä käytetään yleisesti hyväksyttyihin standardeihin perustuvia tiedonsiirtoprotokollia sekä tietoformaatteja. Diplomityössä esitellään keskeiset teknologiat ja menetelmät sähköisen tiedonvälityksen toteuttamiseen. Lisäksi työssä vertaillaan erilaisia vaihtoehtoja, joilla sähköinen tiedonvälitys voidaan toteuttaa. Vaihtoehtoina työssä ovat tiedonvälityspalveluiden ostaminen toiselta yritykseltä, olemassa olevan valmiin ohjelmiston hyödyntäminen, tai kokonaan uuden sovellusalustan kehittäminen. Työssä kuvaillaan palvelukeskeisen sovellusalustan toteutus, joka mahdollistaa tehokkaan sekä joustavan tiedonvälityksen sovellusten välillä. Alustan tarjoamien palveluiden päälle voidaan rakentaa erilaisia liiketoimintaa tukevia palveluita, jotka voivat hyödyntää sovellusalustan tarjoamia toiminnallisuuksia. Alustan toteutusta arvioidaan kolmen liiketoimintaskenaarion toteutuksesta saatujen kokemusten perusteella.

Open Innovation is a relatively new concept which involves a change of paradigm in the R+D+i processes of companies whose aim is to create new technologies or new processes. If to this change, we add the need for innovation in the new green and sustainability economy, and we set out to create a collaborative platform with a learning space where this can happen, we will be facing an overwhelming challenge which requires the application of intelligent programming technologies and languages at the service of education.The aim of the Green IDI (Green Open Innovation) ¿ Economic development and job creation vector in SMEs, based on the environment and sustainability project is to create a platform where companies and individual researchers can perform open innovation processes in the field of sustainability and the environment.The Green IDI (Green Open Innovation) project is funded under the program INNPACTO by the Ministry of Science and Innovation of Spain and is being developed through a consortium formed by the following institutions: GRUPO ICA; COMPARTIA; GRUPO INTERCOM; CETAQUA and the Instituto de Investigación en Inteligencia Artificial (IIIA) from Consejo Superior de Investigaciones Científicas (CSIC). Also the consortium include FUNDACIÓ PRIVADA BARCELONA DIGITAL; PIMEC and UNIVERSITAT OBERTA DE CATALUNYA (UOC).Sustainability and positive action for the environment are considered the principle vector of economic development for companies. As Nicolás Scoli says (2007) ¿in short, preventing unnecessary consumption and the efficient consumption of resources means producing greater wealth with less. Both effects lead to reduced pollution linked to production and consumption¿.The Spanish Sustainable Development Strategy (EEDS) plan defends consumption and sustainable production linked to social and economic development by adhering to the commitment not to endanger ecosystems and abolishing the idea that economic growth is directly proportional to the deterioration of the environment.Uniting the Open Innovation and New Green Economy concepts leads to the "Green Open Innovation¿ Platform creation project.This article analyses the concept of open innovation and defines the importance of the new green and sustainable economy. Lastly, it proposes the creation of eLab. The eLab is defined as an Open Green Innovation Platform personal and collaborative education space which is fed by the interactions of users and which enables innovation processes based on new green economy concepts to be carried out.The creation of a personal learning environment such as eLab on the Green Open Innovation Platform meets the need to offer a collaborative space where platform users can improve their skills regarding the environment and sustainability based on collaborative synergies through Information and Communication Technologies.

Software integration is a stage in a software development process to assemble separate components to produce a single product. It is important to manage the risks involved and being able to integrate smoothly, because software cannot be released without integrating it first. Furthermore, it has been shown that the integration and testing phase can make up 40 % of the overall project costs. These issues can be mitigated by using a software engineering practice called continuous integration. This thesis work presents how continuous integration is introduced to the author's employer organisation. This includes studying how the continuous integration process works and creating the technical basis to start using the process on future projects. The implemented system supports software written in C and C++ programming languages on Linux platform, but the general concepts can be applied to any programming language and platform by selecting the appropriate tools. The results demonstrate in detail what issues need to be solved when the process is acquired in a corporate environment. Additionally, they provide an implementation and process description suitable to the organisation. The results show that continuous integration can reduce the risks involved in a software process and increase the quality of the product as well.
PRELIMINARILY DEVELOPMENT OF A MOISTURE-ACTIVATED BIORESORBABLE POLYMERIC PLATFORM FOR DRUG DELIVERY

Bioresorbable polymeric films were prepared by solvent casting using a tyrosine-derived polycarbonate and metronidazole (MDZ) as the model drug at 2.5%, 5% and 10% (w/w). Drug loading did not affect the water uptake, drug release, polymer degradation or erosion profiles. All devices released approximately 85% (w/w) of the drug within a 1.5 h period. This may be attributed to the rapid water uptake of the polymer. An increase in the water uptake correlated with a linear rate increase of the polymer degradation (0.968 ≤ R2 ≤ 0.999). Moreover, MDZ presented a remarkable plasticizing effect for the polymer and drug loading exerted a significant impact on the mechanical properties of the obtained films. The results obtained can be used to further the development of novel biocompatible and biodegradable polymeric platforms for the delivery of metronidazole and other drugs in a broad range of pharmaceutical applications.

This thesis presents two graphical user interfaces for the project DigiQ - Fusion of Digital and Visual Print Quality, a project for computationally modeling the subjective human experience of print quality by measuring the image with certain metrics. After presenting the user interfaces, methods for reducing the computation time of several of the metrics and the image registration process required to compute the metrics, and details of their performance are given. The weighted sample method for the image registration process was able to signifigantly decrease the calculation times while resulting in some error. The random sampling method for the metrics greatly reduced calculation time while maintaining excellent accuracy, but worked with only two of the metrics.

Today cloud computing is the next stage in development information-oriented society in field of information technologies. Great attention is paid to cloud computing in general, but the lack of scientific consideration to components brings to the problem, that not all aspects are well examined. This thesis is an attempt to consider Platform as a Service (a technology of providing development environment through the Internet) from divergent angles. Technical characteristics, costs, time, estimation of effectiveness, risks, strategies that can be applied, migration process, advantages and disadvantages and the future of the approach are examined to get the overall picture of cloud platforms. During the work literature study was used to examine Platform as a Service, characteristics of existent cloud platforms were explored and a model of a typical software development company was developed to create a scenario of migration to cloud technologies. The research showed that besides all virtues in reducing costs and time, cloud platforms have some significant obstacles in adoption. Privacy, security and insufficient legislation impede the concept to be widespread.

The new product development process is a massive investment to a company that aims to reduce their products’ time-to-market. Capability to shorter time-to market allows longer life-cycle to products which are introduced to market earlier but also give advantage to start product launch later while simultaneously learning from customer behavior and competitors. The product launch support operations are the last ramp-up activities before the product launching. This study defines what these operations mean in a product platform and how they can be streamlined to be more efficient. The methodology includes interviews, innovative group brainstorming and regular working group meetings. The challenges concerning the current situation of product launch support operations are allocated into four categories: General, Process, Project Resources and Project Management including altogether ten sub challenges. The challenges include issues related to technology and marketing management, branding strategy, organizing the global platform structure, harmonizing processes and clarifying handovers between shareholders in the process. The study makes a suggestion of a new Product Launch Support organization and clarification of its roles, responsibilities and tasks. In addition a new project management tool and Lessons Learned are suggested to improve the project management. The study can be seen as a pre-study when having an aim at combining technological and marketing know-how in the product ramp-up process before actual production. The future proceedings are suggested to include more detailed specifications and implementation in order to reach the long range target, reduced the time-to-market.

Bacteria can exist as planktonic, the lifestyle in which single cells exist in suspension, and as biofilms, which are surface-attached bacterial communities embedded in a selfproduced matrix. Most of the antibiotics and the methods for antimicrobial work have been developed for planktonic bacteria. However, the majority of the bacteria in natural habitats live as biofilms. Biofilms develop dauntingly fast high resistance towards conventional antibacterial treatments and thus, there is a great need to meet the demands of effective anti-biofilm therapy. In this thesis project it was attempted to fill the void of anti-biofilm screening methods by developing a platform of assays that evaluate the effect that screened compounds have on the total biomass, viability and the extracellular polysaccharide (EPS) layer of the biofilms. Additionally, a new method for studying biofilms and their interactions with compounds in a continuous flow system was developed using capillary electrochromatography (CEC). The screening platform was utilized with a screening campaign using a small library of cinchona alkaloids. The assays were optimized to be statistically robust enough for screening. The first assay, based on crystal violet staining, measures total biofilm biomass, and it was automated using a liquid handling workstation to decrease the manual workload and signal variation. The second assay, based on resazurin staining, measures viability of the biofilm, and it was thoroughly optimized for the strain used, but was then a very simple and fast method to be used for primary screening. The fluorescent resazurin probe is not toxic to the biofilms. In fact, it was also shown in this project that staining the biofilms with resazurin prior to staining with crystal violet had no effect on the latter and they can be used in sequence on the same screening plate. This sequential addition step was indeed a major improvement on the use of reagents and consumables and also shortened the work time. As a third assay in the platform a wheat germ agglutinin based assay was added to evaluate the effect a compound has on the EPS layer. Using this assay it was found that even if compounds might have clear effect on both biomass and viability, the EPS layer can be left untouched or even be increased. This is a clear implication of the importance of using several assays to be able to find “true hits” in a screening setting. In the pilot study of screening for antimicrobial and anti-biofilm effects using a cinchona alkaloid library, one compound was found to have antimicrobial effect against planktonic bacteria and prevent biofilm formation at low micromolar concentration. To eradicate biofilms, a higher concentration was needed. It was also shown that the chemical space occupied by the active compound was slightly different than the rest of the cinchona alkaloids as well as the rest of the compounds used for validatory screening during the optimization processes of the separate assays.
