The aim of this master thesis is to develop a laboratory process that Saab Ericsson Space AB (SE) can use to demonstrate their fault tolerant computer systems at exhibitions. The process is an inverted pendulum shaped as a rocket to symbolize that the company develops fault tolerant control systems for satellites and carrier rockets e.g. for Ariane 5.
The inverted pendulum is a classical
The purpose of this qualitative study, with a constructivist approach, was to examine how professionals work with children as next of kin to chronically ill patients in somatic care. Through a content analysis, using local guidelines and policy documents for the work with children as next of kin, as well as semi-structured interviews focusing on how the professionals themselves describe their
To find new ways for collaboration between the Swedish public sector and the civil society, and to promote non-profit voluntary (NPVOs) actors as local welfare producers, the collaboration format Idéburet – Offentligt Partnerskap (IOP) was launched. The purpose of this explorative study is to examine why local and regional authorities enters into IOP as a form of collaboration with NPVOs. The stud
Background: Sharing of data about variation and the associated phenotypes is a critical need, yet variant information can be arbitrarily complex, making a single standard vocabulary elusive and re-formatting difficult. Complex standards have proven too time-consuming to implement. Results: The GEN2PHEN project addressed these difficulties by developing a comprehensive data model for capturing biom
Laminar burning velocity measurements of 50:50 and 85:15% (by volume) H-2-CO mixtures with O-2-N-2 and O-2-He oxidizers were performed at lean conditions (equivalence ratio from 0.5 to 1) and elevated pressures (1 atm-9 atm). The heat flux method (HFM) is employed for determining the laminar burning velocity of the fuel-oxidizer mixtures. HFM creates a one-dimensional adiabatic stretchless flame w
The morphology and molecular mechanisms of animal photoreceptor cells and eyes reveal a complex pattern of duplications and co-option of genetic modules, leading to a number of different light-sensitive systems that share many components, in which clear-cut homologies are rare. On the basis of molecular and morphological findings, I discuss the functional requirements for vision and how these have
Wavelet analysis was used to calculate turbulence and mean velocity levels for LDV measurements made in a four valve spark ignition engine. Five different camshafts were tested, and they produce significantly different flow behaviour. The standard cam gives tumble and with valve deactivation, swirl is produced. One camshaft with early inlet valve closing and two camshafts with late inlet valve clo
Popular Abstract in Swedish Käkförsedda havsborstmaskar (polychaeter) var artrika och vanliga i de tidigpaleozoiska haven. Maskarnas käkar, benämda scolecodonter i den vetenskapliga litteraturen, är mycket vanliga mikrofossil i sedimentära bergarter, främst kalkstenar av denna ålder. Mycket pekar därför på att de ofta utgjorde en väsentlig del av bottenfaunan. Trots mångfalden av scolecodonter harJawed polychaete annelid worms were abundant and diverse in the early Palaeozoic seas and their jaws (scolecodonts) are common microfossils in sedimentary rocks of that age. Despite their abundance, relatively little work has been focused on these fossils. One reason for this is that their taxonomy has been, and to some extent still is, in a state of disorder, mainly because of a parataxonomic tre
The interaction between cystatin C variants, in which the evolutionarily conserved Gly-11 residue was substituted by Ala, Glu or Trp, and the cysteine proteinases, papain, ficin, actinidin and cathepsin B, was characterized. The substitutions reduced the affinity of binding in a manner consistent with the Gly residue of the wild-type inhibitor, allowing the N-terminal region to adopt a conformatio
PURPOSE: To investigate if stents with hooks and barbs will improve stent-graft fixation in the abdominal aorta. METHODS: Sixteen- to 24-mm-diameter Dacron grafts were deployed inside cadaveric aortas. The grafts were anchored by stents as in endovascular abdominal aortic aneurysm repair. One hundred thirty-seven stent-graft deployments were carried out with modified self-expanding Z-stents with (
Polymer-droplet interactions have been Studied in AOT/water/isooctane oil-continuous microemulsions mixed with an amphiphilic graft copolymer. or with the parent homopolymer (AOT = sodium bis(2-ethylhexyl) sulfosuccinate). The graft copolymer has an oil-soluble poly(dodecyl methacrylate) backbone and water-soluble poly(ethylene glycol) side chains. Pseudo-ternary polymer/droplet/isooctane phase di
The intangible nature of software means that traditional processes for managing product development are not sufficiently effective. This, in combination with the increasing share of software in technical products, has had the effect of making it difficult to identify improvement proposals for engineering processes in many cases. This thesis uses both qualitative and quantitative research methods t
Popular Abstract in Swedish Att fasta under ramadan är både en glädje och ett jihad för det muslimska samfundet i Java, och fastan är utan tvekan den mest aktade ritualen i det muslimska Indonesien (och på andra håll i den muslimska världen). Att avhålla sig från mat, dryck och sexuella relationer från gryning till skymning i en hel månad i ett tropiskt klimat - och att fylla nätterna med extra frFASTING DURING THE holy month of Ramadan is both a joy and a jihad for the Islamic community in Java, and it is arguably the most highly esteemed Muslim ritual in Indonesia (and beyond). To be given the opportunity to abstain from food, drink and sexual relations from the early morning hours until sunset during an entire month in a tropical climate - only to fill the nights with additional and sup
BACKGROUND: The clinically significant antigens of the Duffy (Fy [FY]) blood group system are expressed on the red cell form of the FY glycoprotein, a promiscuous chemokine receptor and also a receptor for malarial parasites. After the cloning of cDNA coding for FY glycoprotein, the molecular basis of the three major alleles (Fya/Fyb/Fy) has been established. Because of the mistyping of the silent
The brick kiln at Saltsjö Boo is one of very few such structures known from medieval Sweden. Approx ¾ of the kiln has been excavated in successive short excavations from 2006 to 2011. Carbon 14 and TL (Thermoluminiscence) analyses indicate that the kiln has been in operation from c. 1250 to c.1450. This paper presents the results of the excavations and discusses the production of bricks and indust
In the module allocation problem a collection of software modules are to be assigned to physical processing nodes, subject to execution and communication cost. The cost of an allocation is a function of the execution costs and the communication costs for any pair of modules allocated to distinct processors. The module allocation problem has been well studied and is known to be NP-complete except f
Purpose of this paper The expression Enhanced Liability refers to clauses in a contract which obligation one of the partners to accept extended liability for future claims payments beyond normal standards of transport law, conventions or national standard terms and conditions for logistics service intermediaries, logistics service providers and carriers. This paper provides explanations and unders
Viewing information systems (IS) as services is beneficial but still an unexplored approach for IS in organizations. The aim of this exercise is to contribute to the knowledge base on designing IS as services. This paper presents an analysis of enterprise resource planning (ERPs) systems through the lens of service oriented architecture (SOA). Services are explained and defined through SOA theory.
Something has happened in the field of Service Studies. With the introduction of what has been called Service Dominant Logic a large proportion of the established theories related to service as a phenomenon has been challenged. From previously having been defined as something different from the tangible things we buy (goods); i.e. a residual, service defined out of what service is not, the new lin
Germline mutations in the MEN1 gene predispose to the multiple endocrine neoplasia (MEN1) syndrome; however, approximately 10-20% of patients with MEN1 do not have a detectable MEN1 mutation. A rat strain with multiple endocrine tumours, a phenotypic overlap of both MEN1 and MEN2, has been reported to have a homozygous germline p27 (CDKN1B) mutation. Recently, two MEN1 mutation-negative MEN1 syndr
