There is no standard format for posting blog entries, which results in many different web feed formats and APIs being used. This thesis work addresses the problem by determining the feasibility of the development of a plug-in based architecture, used in a mobile blogging application compatible with multiple service providers. During the study, a definition of what a feasible architecture would be was made based on requirements set by the stakeholders. Six models that complied with this definition were designed and compared. One of them was selected for prototyping. The prototyping phase was intended to test if the architecture could be implemented in a mobile environment. The study revealed that it is feasible to develop a plug-in based architecture to solve the problem, although with some limitations due to the dependency of libraries for streaming XML transformations not yet implemented in J2ME. / Det finns inget standardformat för att posta ett blogginlägg, vilket resulterar i att många olika web feed-format och APIer används. Det här examensarbetet angriper problemet genom att undersöka om det är genomförbart att utveckla en plug-inbaserad arkitektur för en applikation till mobiltelefoner, som är kompatibel med flera olika bloggtjänster. Under studiens gång definierade vi vad termen genomförbart skulle innebära, baserat på krav från olika intressenter. Sex modeller som uppfyllde definitionen utvecklades och jämfördes. En av dessa valdes ut för att användas som grund för en prototyp. Prototypfasen avsåg att bevisa om arkitekturen kunde implementeras i en mobil miljö. Studien visade att det är genomförbart att utveckla en plug-inbaserad arkitektur för att lösa problemet, dock med några begränsningar på grund av beroende av bibliotek för strömmande XMLtransformationer som ännu inte implementerats i J2ME.

Dans le contexte de la théorie bayésienne et de théorie de la décision, l'estimation d'une densité prédictive d'une variable aléatoire occupe une place importante. Typiquement, dans un cadre paramétrique, il y a présence d’information additionnelle pouvant être interprétée sous forme d’une contrainte. Cette thèse porte sur des stratégies et des améliorations, tenant compte de l’information additionnelle, pour obtenir des densités prédictives efficaces et parfois plus performantes que d’autres données dans la littérature. Les résultats s’appliquent pour des modèles avec données gaussiennes avec ou sans une variance connue. Nous décrivons des densités prédictives bayésiennes pour les coûts Kullback-Leibler, Hellinger, Kullback-Leibler inversé, ainsi que pour des coûts du type $\alpha-$divergence et établissons des liens avec les familles de lois de probabilité du type \textit{skew--normal}. Nous obtenons des résultats de dominance faisant intervenir plusieurs techniques, dont l’expansion de la variance, les fonctions de coût duaux en estimation ponctuelle, l’estimation sous contraintes et l’estimation de Stein. Enfin, nous obtenons un résultat général pour l’estimation bayésienne d’un rapport de deux densités provenant de familles exponentielles. / Abstract: In the context of Bayesian theory and decision theory, the estimation of a predictive density of a random variable represents an important and challenging problem. Typically, in a parametric framework, usually there exists some additional information that can be interpreted as constraints. This thesis deals with strategies and improvements that take into account the additional information, in order to obtain effective and sometimes better performing predictive densities than others in the literature. The results apply to normal models with a known or unknown variance. We describe Bayesian predictive densities for Kullback--Leibler, Hellinger, reverse Kullback-Leibler losses as well as for α--divergence losses and establish links with skew--normal densities. We obtain dominance results using several techniques, including expansion of variance, dual loss functions in point estimation, restricted parameter space estimation, and Stein estimation. Finally, we obtain a general result for the Bayesian estimator of a ratio of two exponential family densities.

In the welding of more sensitive metals such as stainless steel, titanium and some specific nickel alloys, the presence and application of a protective gas is essential. Without the use of a nonreactive shielding gas, defects occur in or adjacent to the weld joint, which vary from light discoloration of the weld bead to the direct onset and propagation of cracks. The supply of shielding gas is usually via the welding tool. Unfortunately, when it comes to welding pipes, the problem arises when the root bead comes into contact with the oxygen present within the pipe. Since the shielding gas supplied from the welding tool has no possibility of penetrating into the pipe and protecting the melt from the oxygen, the result consequence will be defects in the weld bead. To prevent this from happening, the pipes are sealed before welding and the oxygen in the pipe is purged and replaced with protective gas. Due to the fact that pipe welding operations concern a vast spectrum of pipe dimensions, complications arise for the welding operator as the solutions available have a low degree of adaptability. Thus, the purpose of this project is to investigate the possibility of designing and developing a new method of supplying root gas protection that can be adapted to several pipe diameters. Field studies at welding companies resulted in the clarification of which diameter spans the root gas protection solution should comply with, the pipe diameter span to cater for was identified as 25-100 mm in diameter. Requests were also made regarding the robustness of the product, with expressed desire for the product to withstand the strenuous working environment often encountered during welding operations. Solution proposals were produced which later developed into six separate concepts. From these six concepts, one was selected as the foremost solution and further developed for construction. The concept was sketched out and reproduced using CAD and a model was made using 3D printers. The model showed a need for modifications as it was not of a sufficiently adaptable nature. A modified model was thus developed and manufactured using a 3D printer, this modified model showed better results of adaptation to different pipe diameters. Furthermore, a flow analysis of the gas as it enters via the root gas plug and into the pipe was conducted, to verify total distribution of the gas within the pipe. The material with which to construct the concept with will be silicone infused with additives to make it more heat resistant and more resistant to wear. However, the exact mixture of silicone and additives in question was not available for this project but is something that is intended for future work. The concept meets the specified requirements of being applicable to multiple pipe diameters, more specifically so meeting the wishes of those active within the industry, covering a pipe span of 25- 100 mm. / Vid svetsning av mer känsliga metaller såsom rostfritt stål, titan och vissa specifika nickellegeringar är närvaron och tillämpningen av en skyddsgas väsentligt. Utan nyttjandet av en icke reaktiv skyddsgas uppkommer defekter i eller intill svetsfogen, vilka varierar från lätta missfärgningar av svetssträngen till den direkta uppkomsten och propageringen av sprickor. Tillförseln av skyddsgas sker vanligtvis via svetsverktyget. När det kommer till svetsning av rör uppstår dessvärre problemet att rotsträngen kommer i kontakt med syret som finns på insidan av röret. Eftersom att den skyddsgas som tillförs från svetsverktyget inte har någon möjlighet att tränga sig in i röret och skydda smältan från syret kommer det resultera i en svetssträng med defekter. För att förhindra detta från att ske tätas rören innan svetsning och syret i röret ersätts med skyddsgas. Eftersom att de rör som skall sammanfogas förekommer i flera dimensioner uppstår komplikationer för svetsoperatören ty de lösningar som finns tillgängliga har låg anpassningsgrad. Därmed är syftet med detta projekt att undersöka möjligheten att designa och utveckla ett nytt rotgasskydd som kan anpassas till flera diametrar. Fältstudier hos svetsföretag resulterade i ett tydligt spann för vilka diametrar som bör tillgodoses med sagda rotgasskydd, detta spann av rördiametrar var 25-100 mm. Det uppgavs även önskemål om säkerställning av att produkterna är robusta nog att klara den påfrestande arbetsmiljö som ofta förekommer vid svetsning. Lösningsförslag lades fram vilket senare utvecklades till sex separata koncept. Från dessa sex koncept utsågs en som den främsta lösningen och togs vidare till konstruktion. Konceptet skissades upp i CAD och en modell gjordes i 3D-skrivare. Modellen visade upp behov på modifieringar då den inte var av tillräckligt anpassningsbar karaktär. En modifierad modell togs därmed fram och tillverkades i en 3D-skrivare, denna modifierade modell visade bättre prov på anpassning till olika  rördiametrar. Vidare gjordes en flödesanalys av gasen då den färdas in via rotgaspluggen, vilket visade att gasen fyller röret som önskat. Materialet som konceptet kommer tillverkas i är silikon med tillförda additiv för att göra det mer värmebeständigt och mer resistent mot slitage. Den exakta blandningen av silikon och additiv i fråga var dock inte tillgängliga till detta projekt utan är något som får gå till vidare arbete. Konceptet uppfyller kraven på anpassning till flera rördiametrar och möter mer specifikt även önskemålet från branschaktiva med dess spann på 25-100 mm.

In realizing a portable chemical analysis system, adequate partitioning of a reusable component and a disposable is required. For successful implementation of micromachined sensors in an instrument, reliable methods for interconnection and interface are in great demand between these two major parts. This thesis work investigates interconnection methods of micromachined chip devices, a hybrid fluidic interface system, and measurement circuitry for completing instrumentation. The interconnection method based on micromachining and injection molding techniques was developed and an interconnecting microfluidic package was designed, fabricated and tested. Alternatively, a plug-in type design for a large amount of sample flow was designed and demonstrated. For the hybrid interface, sequencing of the chemical analysis was examined and accordingly, syringe containers, a peristaltic pump and pinch valves were assembled to compose a reliable meso-scale fluidic control unit. A potentiostat circuit was modeled using a simulation tool. The simulated output showed its usability toward three-electrode electrochemical microsensors. Using separately fabricated microsensors, the final instrument with two different designs--flow-through and plug-in type was tested for chlorine detection in water samples. The chemical concentration of chlorine ions could be determined from linearly dependent current signals from the instrument.

A frequency response tracer technique was used to study the hydraulic properties of a laboratory flow through reactor with variations in reactor size, flow rate and applied mixing. At any one set of conditions the reactor was studied over a range of input sine wave frequencies. Theoretical models consisting of in-series networks of completely mixed segments, plug flow segments, and dead space allowances were developed to approximate the experimental findings. / Thesis / Master of Engineering (ME)
