One of the most crucial decisions when developing a system based on Service Oriented Architecture is to select an appropriate server which will be the ground for building the application. Similar to databases, an application server has significant influence on efficiency, stability, and security of entire system. During the preparation of architecture for system development one has to decide which available application server would be optimal for hosting and maintaining v Web Services in the given case. There are multiple significant criteria that lead to the proper choice. The impact on a decision among other things is type of the physical machine on which the application server is installed, estimated number of simultaneous clients, and sizes of requests and responses between clients and server. The goal for this thesis is to conduct the comparative analysis of the most commonly used application servers using Service Oriented Architecture and to determine which server should be applied in which particular cases. Performance and load tests will be conducted using SoapUI application.

Polyhedral foams offer large gas-liquid interfacial area associated with a small amount of liquid. Therefore, if a solute adsorbs preferentially at the interface, the concentration of the solute in the foam will be greater than in the solution from which the foam has been generated. This effect provides a simple method of concentrating materials which have a tendency to adsorb on the gas-liquid interface. This is particularly relevant to biomaterials like whole cells, proteins, enzymes etc., which are surface active and are present in low concentrations in the broth. Foam separation has therefore attracted considerable attention, and several reports exist in literature on concentrating cells, proteins and enzymes using foams. Foam separation is based on the difference in surface activity of the components to be separated. A surface active molecule consists of a lyophobic and a lyophilic group. (As water is commonly used as a solvent, the lyophilic and lyophobic groups are called hydrophilic and hydrophobic groups, respectively). When dissolved in a solvent, the presence of lyophobic groups in the interior of the solvent distorts the solvent liquid structure, thereby increasing the free energy of the system.

<p>Web Services har vuxit i popularitet de senast åren. Användningen av inbyggda system</p><p>ökar också ständigt, och möjligheten att göra inbyggda system tillgängliga via Web Services öppnar nya möjligheter.</p><p>Detta arbete visar på möjligheter och problem med standardiserade textbaserade protokoll för kommunikation i inbyggda system med små resurser. XML-RPC och SOAP studeras ur detta perspektiv. SOAP befinns vara mer komplext att implementera stöd för än XMLRPC i den begränsade testmiljön, som har 32kB internminne. XML-RPC visar sig ge fördelar över proprietära protokoll främst när det gäller underhållbarhet och återanvändbarhet.</p>

<p>The business pressures which companies and organisations encounter are steadily growing. They continuously have to improve their efficiency to keep up with these new developments. One very important aspect in doing so is the reinforced adoption of computer based information systems. This paper focuses on a computer based system which is able to automate everyday business communication between distributed team members.</p><p>Reliable and confidential message delivery, event notification, the integration of different end devices (mobile phones, PCs etc.) and the message transport across different networks (wireless, wired) have been allocated as the main system requirements. Based on these requirements the performance of two middleware technologies, namely CORBA and Web services, has been compared. The result of this comparison was that both technologies are suited to use for implementing such a system but both too, have strengths and weaknesses in achieving the stated requirements.</p><p>CORBA for example, due to several supporting, already included services, allows the programmer to concentrate on the application development itself and use these services to ensure reliable and confidential message transmission. Additionally, CORBA is very efficient in using the bandwidth of the underlying communication network, but makes higher demands to the memory space available on clients. This is critical, if clients are mobile devices with limited resources.</p><p>Web service technology is much more modest than CORBA with respect to the client side memory space, but message transmission requires much more bandwidth. Further one there are no built-in security and reliability services available for Web services, like there are for CORBA. Hence it is up the application programmer to manually implement these features; however he has not necessarily develop everything from scratch but can resort to already existing specifications, still having the freedom of developing specially tailored features.</p><p>In short could be stated that CORBA is more consequential and consistent and WS technology is more adjustable and flexible.</p>

<p>This thesis describes the development of a SOA-based architecture for integrating large EDI-using manufacturing companies purchasing processes with smaller non-EDI capable manufacturing companies, using online services.</p><p>The underlying need for this project lies with the fact that these small manufacturing companies risk to miss out on business, due to their inability to communicate via the industry standard EDI format. At the same time, getting EDI-capable involves significant investments in software licenses, connectivity services and consulting or training that these small companies may not be ready to make. The mentor company of this thesis project, System Andersson, produces resource planning software for this type of companies and would like to be able to provide them with an easy to use way of “jacking in” EDI support into their businesses, without having to make such significant investments. Ideally this feature would be developed as a standalone subscription based service that could be provided to users in such a way that their existing System Andersson software could connect to it and no further hard- or software would be needed on site. This EDI-enabling should be as easy as to be entirely transparent for the end-user companies. The task handed to the author was thus to develop an architecture for how such a subscription based service could be developed. Furthermore, in order to promote re-use and simplify development, the architecture was to be based on SOA concepts.</p><p>As a result of the project, such an architecture has been developed. The architecture details two services for translating and storing for later delivery a number of EDI message types of the EDIFACT variety. The architecture also specifies communications protocols (SOAP over HTTPS and AS2 over HTTPS) and APIs (web services) for how to communicate with these services. These specifications can be used to implement a system that performs the necessary integration, so that the smaller companies may indeed communicate via EDI.</p><p>The fitness of the developed architecture has been tested by implementing a prototype version of such a system based on it. It has also been validated by way of comparing to how well it adheres to SOA design principles. All in all, this design appears to be quite sound and presents a working solution to the studied problem.</p>

<p>This Master thesis enhances an existing library search system with a new dynamic web interface and introduces the ability to perform remote searches by using Web Services. The remote search functionality also includes the ability to compress SOAP-messages, this functionality is optional. The system is implemented using the Microsoft.NET Framework with Visual Studio C#. A library needs to store information about articles and we have chosen to use a Sybase Adaptive Server Anywhere database.</p><p>The practical part of this thesis describes the architecture of our implementation and the design process.</p><p>The theoretical part is a comparative study between dynamically created web pages and static pages, SOAP-compression versus no compression, SOAP-optimization versus no optimisation and the use of Web Services locally versus local classes.</p>

<p>This master’s thesis discusses the evolution of DataPartner’s application "Inventera". Inventera is designed to do inventory of stock on handheld computers and integartes with SPCS Administration. Inventera is enhanced with a wireless connection and the SPCS API is wrapped with Web Services. The theoretical part of this thesis examines diffrent possibilities to increase reusability by using web service technology when developing software. A case study of the SPCS API is used in order to study differences between using no Web Services at all, static web services or dynamic web services.</p>

Televizija yra viena iš socializacijos priemonių, kurią žiūrima tam, kad sužinoti svarbią informaciją arba norint gerai praleisti laiką. Be to, televizija suteikia ir savotišką pasitenkinimo jausmą, kai kiekvienas žiūrintysis turi galimybę tapatintis su vaizduojamų personažų herojais, kuriuose gali identifikuoti save. Per paskutinius metus, Lietuvoje išleidžiama po kelis lietuviškus serialus, kurie susilaukia teigiamo žiūrovų įvertinimo (TNS Gallup duomenimis serialas „Moterys meluoja geriau patenka į populiariausių laidų penketuką). Nenuostabu, kad žiūrovas renkasi lietuvišką muilo operos variantą, kuriame išvysta priimtinus kultūrinius modelius, artimus vyriškumo ir moteriškumo modelius su kuriais gali tapatintis ir atrasti dalelę savęs. Todėl šiame darbe siekta išanalizuoti ir pateikti moteriškumo reprezentacijų sampratų įvairovę serialuose „Emilija“ ir „Moterys meluoja geriau“. Pirmojoje literatūros analizės dalyje aptariama feministinio moteriškumo samprata, išskiriami pagrindiniai radikaliojo, liberaliojo, socialistinio ir psichoanalitinio feminizmo autorių požiūriai. Antrojoje darbo dalyje išskiriama psichoanalizės įtaka feministiniuose tyrimuose, pristatoma vizualinio malonumo svarba kine, aptariami feministinio įgalinimo būdai žiniasklaidoje. Trečiojoje darbo dalyje pristatomos moterų reprezentacijų problematikos, pristatomi moterų ir muilo operų žiūrėjimo ypatumai, nagrinėjami moterų stereotipų vaidmuo žiniasklaidoje ir feministinėje literatūroje. Tyrimo... [toliau žr. visą tekstą] / Television is one of the agent tools that are playing socialization role. People are watching TV in order to receive relevant information or to spend a leisure time. Therefore, television provides particular delectation; in the meantime, everyone has opportunity to identify themselves in pictorial characters. In the recent years, screens are showing several new Lithuanian soap operas, and it has congenial viewer’s assessment (TNS Gallup records that serial “Moterys meluoja geriau” is one of the popular watching program and rating between five best programs). No, wonder why people are choosing to watch Lithuanian soap operas versions, where they can find acceptable cultural models, familiar masculinity and femininity patterns in which they can identify an element of themselves. This research seeks to analyze and to propose diversions of women femininity concepts in the serials “Emilija” and “Moterys meluoja geriau”. The first theoretical part of this work is discussing about feministic femininity concepts, excluding radical, liberal, socialistic and psychoanalytic essential scholarship approaches. The second part is about psychoanalytic viewpoint influence in feministic studies, including visual pleasure significance and feministic empowerment in the media. The third part of this research is representing women’s agency proposition, analyzes women and soap opera’s particularity and examines women’s stereotypes in the media and feministic theory. The research results has... [to full text]

<p>This thesis examines how multilingual spaces in South Africa are imagined and reconstructed through the use of scripted codeswitching in 7de Laan. It explores how the socio-political discourses and other ideologies from the broader South African context shape and influence the ways in which the soap reconstructs multilingual spaces and the identities that exist within these spaces through language and language practices. In the literature presented in this study I explore various theories and case studies that examine Afrikaans and its indexicality in our&nbsp / contemporary society, the conventions of soap opera in representing &lsquo / reality&rsquo / to society, the role of codeswitching in multilingual mass communication, the policies and ideologies that govern post apartheid television and finally the link between ideology, the media, language and imagined identities.. These five overarching themes often overlap throughout this thesis. My investigation of the main questions set in this thesis is based on a triangulated analysis of (a) a five episode transcript of the soap, (b) solicited viewer perceptions gleaned from questionnaires and (c) unsolicited social media commentaries. This analysis is framed by a poststructuralist critical analysis with a specific focus on how social practices and contemporary ideologies manifest in the discourse of the soap. This approach views discourse as the juncture where identity, stereotypes and power are negotiated, enforced, imagined and challenged. In this thesis I argue that the conspicuous absence of indigenous African languages and the use of standard white Afrikaans as the lingua franca in the soap creates an unrealistic utopian portrayal of the new South Africa that naturalises white Afrikaans culture and marginalises other indigenous cultures and languages. I argue that the soap puts middle class white Afrikaners at the epicentre of South African society thus enforcing the idea that non-whites still need to conform to white Afrikaans standards and norms at the expense of their own culture and languages despite the inception of democracy. The soap offers no depictions of resistance to this dominant white Afrikaans culture, thus misleadingly portraying it as the uncontested dominant culture of the new South Africa.</p>

It was argued that the social psychology of person perception, mass communications and cultural studies can be related to viewers' representations of television characters. Mass communications needs to incorporate viewers' interpretations and programme structure. Social cognition could satisfy the former need and cultural studies the latter. A literature review showed little research on viewers' interpretations of television programmes. There is a considerable body of research on person perception, gender stereotypes, the effects of viewing and programme structure. A study of viewers' accounts of viewing soap opera showed that they become involved with the characters and find the programmes realistic. Soap opera plays an important role in their lives. Viewers' representations of soap opera characters were examined using multidimensional scaling. This revealed stable, replicable character representations for Dallas, Coronation Street and EastEnders. The representations were compared with the oppositions which structure the programmes, Implicit Personality Theory and Gender Schema Theory. Dallas characters were represented by themes of morality and power/activity. Power was correlated with gender, with some counter-stereotypic females. Coronation Street characters were organised around morality/potency, gender (matriarchal) and approach to life. This related to person prototypes and contrasted with interaction patterns between characters. EastEnders characters were represented by themes of morality/power, gender and approach to life/centrality. Free descriptions validated the attribute ratings and showed further features of the representation. No socio-structural group differences in representation were found. Viewers' character representations were a constructive integration of programme structure and social knowledge. The application of abstract knowledge to a structured domain was discussed. Textual analysis of a narrative identified the 'role of the reader' and textual openness. This was related to stereotypes, narrative expectancies, myth and character representation. Distinct types of divergence in viewers' interpretations of narrative were discovered. Further, a narrative containing two readings was interpreted in four distinct ways by viewers, depending on their perceived relationships with characters. The conclusions and limitations of the research were discussed. Implications for person perception, stereotyping and textual analysis were examined. A taxonomy of factors relating to the interpretation and representation of television drama was presented.
