Scalable and reliable distributed object-oriented computing (DOC) middleware systems is an important technology in, for example, telecommunications service logic and distributed web servers. The Common Object Request Broker Architecture (CORBA), developed by the Object Management Group (OMG) is a speci cation of a common platform for DOC systems. CORBA acts as middleware, by inserting itself betwe
Camera motion estimation, such as relative pose estimation and absolute pose estimation, are fundamental problems in computer vision and robotics. To obtain the motion parameters, classical methods rely on studying the properties of the geometric matrices, e.g., rotation matrix, essential matrix, homography matrix. The well known five-point algorithm was successfully derived using the singular con
We conducted an extensive geophysical field campaign using ground-penetrating radar (GPR) and electrical resistivity tomography (ERT) in a former military area at the archaeological site of Nora (South-Western Sardinia). The purpose was to identify a Phoenician, and then Punic and Roman, necropolis of considerable interest, subject of a long-term investigation and currently under excavation. In th
Collective collapse occurs when a majority of the players in a team suddenly perform below expected level in a match, in spite of a satisfactory start, or when a team underperforms right from the start. Research results from a study on 146 male players and 15 coaches in various team sports at the elite level, and a study on a team involved in a collective collapse, and the opposite, a winning turn
Purpose: Proteases have been implicated in cancer progression and invasiveness. We have investigated the activities, as opposed to simple protein levels, of selected aminopeptidases in urine specimens to serve as potential novel biomarkers for urothelial cancer. Experimental design: The unique urinary proteomes of males and females were profiled to establish the presence of a gender-independent se
Popular Abstract in Swedish En harmonisk morfi är en avbildning som bevarar harmoniska funktioner. De studerades först av Jacobi år 1848, han studerade dem i syfte att hitta harmoniska avbildningar från rummet till planet. Man kan visa att harmoniska morfier är precis de avbildingar som bevarar Brownska rörelser. En Brownsk rörelse är en typ av slumpvandring där riktingen i varje steg är likaförThis thesis consists of 4 papers, their content is described below: Paper I. We present a new method for manufacturing complex-valued harmonic morphisms from a wide class of Riemannian Lie groups. This yields new solutions from an important family of homogeneous Hadamard manifolds. We also give a new method for constructing left-invariant foliations on a large class of Lie groups producing harmoni
Aims: The objectives of this study are to describe our technique in meningomyelocele (MMC) repair, analyzing the results and complications, as well as to study the effect of delay in operation on the complication rate. Patients and Methods: Between March 1997 and October 2012, 48 patients with MMC were treated at Jordan University Hospital by a combined neurosurgical and plastic surgical team. Pat
An automated routine for the continuous calibration of thermographic phosphors was developed as a replacement for the conventional calibration scheme that relied on fixed temperature points. The automated calibration routine was validated using Mg 3 F 2 GeO 4 :Mn as a calibration phosphor. Hardware and software aspects of the calibration process were addressed in this development. The hardware asp
Popular Abstract in Swedish Avhandlingen behandlar robotteknik och de nya möjligheter som den kan ge människor med rörelsehinder. Jag fokuserar på teknikanvändaren och teknikanvändningen, speciellt på vad som gör robothjälpmedel värda att använda. Distinktion görs mellan användvärdhet och användbarhet. Erfarenheter från användning av den rullstolsmonterade robotarmen Manus visar att tekniska krav
In vehicular ad-hoc networks (VANETs) the impact of vehicles as obstacles has largely been neglected in the past. Recent studies have reported that the vehicles that obstruct the line-of-sight (LOS) path may introduce 10-20 dB additional loss, and as a result reduce the communication range. Most of the traffic mobility models (TMMs) today do not treat other vehicles as obstacles and thus can not m
The first part of this study concerns the aqueous phase behavior of mixtures of diglycerol monooleate (DGMO) and glycerol dioleate (GDO) examined by X-ray diffraction (XRD). The ternary phase diagram displays a multitude of liquid crystalline phases (polymorphism). With increasing GDO content the following phase sequence was observed: lamellar (L-alpha); two reversed bicontinuous cubic phases (Q(2
The first EGF-like module of human coagulation factor IX contains a single functionally important calcium ion binding site. We have now shown the dissociation constant for this site to be approximately 160 microM in a recombinant protein fragment consisting of residues 1-85 in human fIX. This represents a approximately 10-fold increase in affinity as compared with the isolated EGF module (residues
A small number of studies have explored children's perception of speakers' voice quality and its possible influence on language comprehension. The aim of this explorative study was to investigate the relationship between the examiner's voice quality, the child's performance on a digital version of a language comprehension test, the Test for Reception of Grammar (TROG-2), and two measures of cognit
