Elaborated Literary Violence: Genre and Ideology of the Two Stories I Sam 22,6-23 and II Sam 21,1-14

The present article focuses on two stories dealing with acts of big blood shed. I Sam 22,6-23 relates the massacre of the priests of Nob; II Sam 21,1-14 is about the execution of seven descendents of Saul, as atonement for Saul's attempt to exterminate the Gibeonites. Most researchers consider both stories or at least certain parts of them old.1 For both stories few verses are regarded as secondary. In this paper I try to reassess the analysis of these stories and will point to indices favoring a late date of origin for both of them. They concern the language in use, intertextual connections and particular motifs. A further indication consists in the fact that the reported events of the stories lack significant resonance in the corpus of the Hebrew Bible. There are only two texts, I Sam 2,33 and Ps 52,2, which allude or refer to I Sam 22,6-23.With regard to the importance of the related events and acts this silence in the Biblical context is astonishing. Interestingly, also in the Book of Chronicles one does not find any allusions to these stories. This raises the question whether the latter were composed after the formation of the book of Chronicles.

Process intensification: From optimised flow patterns to microprocess technology

This thesis is focused on process intensification. Several significant problems and applications of this theme are covered. Process intensification is nowadays one of the most popular trends in chemical engineering and attempts have been made to develop a general, systematic methodology for intensification. This seems, however, to be very difficult, because intensified processes are often based on creativity and novel ideas. Monolith reactors and microreactors are successful examples of process intensification. They are usually multichannel devices in which a proper feed technique is important for creating even fluid distribution into the channels. Two different feed techniques were tested for monoliths. In the first technique a shower method was implemented by means of perforated plates. The second technique was a dispersion method using static mixers. Both techniques offered stable operation and uniform fluid distribution. The dispersion method enabled a wider operational range in terms of liquid superficial velocity. Using dispersion method, a volumetric gas-liquid mass transfer coefficient of 2 s-1 was reached. Flow patterns play a significant role in terms of the mixing performance of micromixers. Although the geometry of a T-mixer is simple, channel configurations and dimensions had a clear effect on mixing efficiency. The flow in the microchannel was laminar, but the formation of vortices promoted mixing in micro T-mixers. The generation of vortices was dependent on the channel dimensions, configurations and flow rate. Microreactors offer a high ratio of surface area to volume. Surface forces and interactions between fluids and surfaces are, therefore, often dominant factors. In certain cases, the interactions can be effectively utilised. Different wetting properties of solid materials (PTFE and stainless steel) were applied in the separation of immiscible liquid phases. A micro-scale plate coalescer with hydrophilic and hydrophobic surfaces was used for the continuous separation of organic and aqueous phases. Complete phase separation occurred in less than 20 seconds, whereas the separation time by settling exceeded 30 min. Fluid flows can be also intensified in suitable conditions. By adding certain additives into turbulent fluid flow, it was possible to reduce friction (drag) by 40 %. Drag reduction decreases frictional pressure drop in pipelines which leads to remarkable energy savings and decreases the size or number of pumping facilities required, e.g., in oil transport pipes. Process intensification enables operation often under more optimal conditions. The consequent cost savings from reduced use of raw materials and reduced waste lead to greater economic benefits in processing.

Shout and Act: an Algorithm for Digital Objects Preservation Inspired from Rescue Robots

We adapt the Shout and Act algorithm to Digital Objects Preservation where agents explore file systems looking for digital objects to be preserved (victims). When they find something they “shout” so that agent mates can hear it. The louder the shout, the urgent or most important the finding is. Louder shouts can also refer to closeness. We perform several experiments to show that this system works very scalably, showing that heterogeneous teams of agents outperform homogeneous ones over a wide range of tasks complexity. The target at-risk documents are MS Office documents (including an RTF file) with Excel content or in Excel format. Thus, an interesting conclusion from the experiments is that fewer heterogeneous (varying skills) agents can equal the performance of many homogeneous (combined super-skilled) agents, implying significant performance increases with lower overall cost growth. Our results impact the design of Digital Objects Preservation teams: a properly designed combination of heterogeneous teams is cheaper and more scalable when confronted with uncertain maps of digital objects that need to be preserved. A cost pyramid is proposed for engineers to use for modeling the most effective agent combinations

Program hosting in communications environment with Reactor and thread pool approach

In this thesis concurrent communication event handling is implemented using thread pool approach. Concurrent events are handled with a Reactor design pattern and multithreading is implemented using a Leader/Followers design pattern. Main focus is to evaluate behaviour of implemented model by different numbers of concurrent connections and amount of used threads. Furthermore, model feasibility in a PeerHood middleware is evaluated. Implemented model is evaluated with created test environment which enables concurrent message sending from multiple connections to the system under test. Messages round trip times are measured in the tester application. In the evaluation processing delay into system is simulated and influence of delay to the average round trip time is analysed.

Teollisten palveluiden tarjoajien ja asiakkaan välisen yhteistyösuhteen kehittäminen

Työssä tutkitaan asennetun laitekannan kunnossapitopalveluun perustuvan yritysten välisen yhteistyösuhteen kehittämisen edellytyksiä. Tutkimus pohjautuu teollisten palveluiden, yritysten välisten yhteistyösuhteiden ja palveluiden kehittämisen osatekijöiden ja menestystekijöiden teoreettiseen tarkasteluun, sekä kohdeyrityksille suoritetun kvalitatiivisen haastattelututkimuksen tulosten analysointiin teoreettisen viitekehyksen valossa. Tavoitteena on muodostaa ehjä ja hallittava kokonaisuus monialaisen ongelmakentän kriittisistä osatekijöistä, sekä niiden keskinäisistä kausaliteeteista. Yritysten välisen yhteistyön lähtökohtana on, että kaikki yhteistyön osapuolet saavuttavat toiminnalla hyötyjä omasta näkökulmastaan tarkasteltuna. Yhteistyösuhteen kehittäminen ja yhteisen arvon toteutuminen edellyttää näin ollen, että tarjottavan palvelukokonaisuuden sisältämät potentiaaliset hyödyt ja toisaalta myös niitä vastaavat riskit ymmärretään sekä palveluntarjoajan että asiakkaan organisaatiossa. Yhteistyösuhteen kehittäminen edellyttää edelleen myös, että suhteen kehittymistä ja saavutettavia hyötyjä pystytään mittaamaan relevanttien mittareiden avulla. Tutkimuksessa keskitytään hyötypotentiaalin selvittämisen edellytyksiin, sekä hyötyjen viestimisen haasteisiin molempia osapuolia palvelevasta objektiivisesta näkökulmasta. Haastattelututkimuksessa havaittujen ongelmakohtien pohjalta eritellään kehityskohteita ja ratkaisuehdotuksia päätöksenteon tueksi sekä laajojen palvelukokonaisuuksien ja niihin liittyvän ongelmakentän hahmottamisen ja hallinnan helpottamiseksi.

A Communication Middleware Quality Enhancement with Qt Framework

In this thesis, a Peer-to-Peer communication middleware for mobile environment is developed using the Qt framework and the Qt Mobility extension. The Peer-to-Peer middleware – called as PeerHood – is for service sharing in network neighborhood. In addition, the PeerHood enables service connectivity and device monitoring functionalities. The concept of the PeerHood is already available in native C++ implementation on Linux platform using services from the platform. In this work, the PeerHood concept is remade to be based on use of the Qt framework. The objective of the new solution is to increase PeerHood quality with using functionalities from the Qt framework and the Qt Mobility extension. Furthermore, by using the Qt framework, the PeerHood middleware can be implemented to be portable cross-platform middleware. The quality of the new PeerHood implementation is evaluated with defined quality factors and compared with the existing PeerHood. Reliability, CPU usage, memory usage and static code analysis metrics are used in evaluation. The new PeerHood is shown to be more reliable and flexible that the existing one.
