Multi Modal Verification for Teleservices and Security Applications (M2VTS)

Ingår i: IEEE International Conference on Multimedia Computing and Systems. - Los Alamitos : IEEE. - 0769502539 ; , s. 1061-1064

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This paper presents the European ACTS project M2VTS which stands for Multi Modal Verification for Teleservices and Security Applications. The primary goal of this project is to address the issue of secured access to local and centralised services in a multimedia environment. The main objective is to extend the scope of application of network-based services by adding novel and intelligent functionalities, enabled by automatic verification systems combining multimodal strategies (secured access based on speech, image or other information). The objectives of the project are also to show that limitations of individual technologies (speaker verification, frontal face authentication, profile identification,...) can be overcome by relying on multi-modal decisions (combination or fusion of these technologies).

Tidskriftsartikel (refereegranskat)abstract
- This paper reports the results of a cross-national comparison of the 'H70' longitudinal study of elders in Gothenburg, Sweden, with the 'Rural Missouri Elders' longitudinal study in Missouri, USA. Analysis of the combined data sets focused on the question of how longevity was affected by culturally divergent forms of social network participation. The H70 study was a representative, systematic 3/10 sample of 70-year-old (in 1971) men and women living in Gothenburg. Follow-up data was gathered when the respondents were 75, 79, 81, 82, 83, 85, 88, 90 and 95 years of age. Face-to-face interviews and physical medical examinations were the major source of data. The Missouri study involved a representative cluster proportional- to-size sample of all rural Missourians 65 years of age and older. Face-to-face interviews were conducted in 1966, 1974 and 1987. Logistic regression and cross-tabular analyses revealed that social networks were important predictors of longevity for both samples. However, marital status and participation in formal organizations predicted longevity for the Americans, whereas contact with children emerged as the predictor variable for the Swedes. Specific functions of the different network patterns in the two countries are discussed.

Willingness to pay for reduced incontinence symptoms

- Objective. To measure the willingness to pay for a reduction in the number of micturitions and urinary leakages for patients with urge incontinence. Patients and methods. A self-administered questionnaire with a binary willingness-to-pay question was administered to 541 patients in Sweden with urge or mixed incontinence; 461 questionnaires were returned. The reduction in micturitions and urinary leakages valued in the willingness-to-pay question was varied randomly between 25% and 50% in two different subsamples. Information was also collected about the number of micturitions and urinary leakages, health-related quality of life and socio-economic characteristics of the patients in the study. Results. Quality of life was significantly related to the severity of the symptoms and was worse than that of the sex- and age-matched general Swedish population. The median (mean) willingness to pay per month was 240 (530) Swedish krona (SEK, £1 = SEK 11.50) for a 25% reduction in micturitions and leakages and SEK 470 (1030) for a 50% reduction in micturitions and leakages. As hypothesized, the willingness to pay was significantly related to the size of the reduction in micturitions and leakages, the initial number of micturitions and leakages, and income. Conclusions. Patients with incontinence problems are willing to pay substantial amounts for a reduction in the number of micturitions and leakages.

Experimental investigation of the interfacial behavior in single-crystal alumina fiber reinforced alumina matrix composites with porous zirconia interphase

Konferensbidrag (refereegranskat)abstract
- Polycrystalline alumina matrix uniaxially reinforced with monocrystalline alumina fiber (sapphire) composites were fabricated following two different processing routes: hot pressing (HP) and hot isostatic pressing (HIP). A porous zirconia coating was included at the fiber/matrix interface of both types of composite. A microindentation technique (push-out) was used to assess the interfacial properties of the two, and this revealed differences in their push-out behavior as observed in the load-deflection curves. After a progressive debonding observed for both composites, a load drop was recorded at the end of the debonding process for the hot isostatic pressed (HIPed) composite whereas a smooth transition could be observed for the hot pressed composite. Another difference was found in the interfacial behavior of the composites during the purely frictional regime. Undulations in the frictional force were seen in the HIPed composite whereas a regular decrease of the friction load was observed in the hot pressed composite. Fiber roughness and thickness of the interphase materials are taken into account to qualitatively explain these differences

Applications of geophysical logging for dilution control in mining

- In mining, waste rock dilution occurs when uneconomic rock is mined and processed with economic mineralized ore. A survey of selected stopes from various Noranda Group mines estimated that aggregate dilution and oreloss stood at 20% and 8% respectively in 1994. Various technologies are being investigated by Noranda Group mines in an ongoing effort to minimize dilution and oreloss. The following three potential applications of geophysical logging have been identified for dilution and oreloss reduction through improved orebody delineation. Increasing orebody sampling at the delineation stage to reduce geological dilution: Diamond core drilling, with geological core-logging, is the most commonly used method for orebody delineation. Unfortunately, the many task-intensive steps and expense of this method constrain the amount of samples one can obtain. However, by allotting an optimum percentage of the delineation drilling budget for geophysical loggin of percussion-drilled holes, increased sampling would occur. Since percussion drilling is significantly cheaper than diamond drilling, more delineation holes could be drilled to better define the ore boundary geometry and, ultimately reduce geological dilution and oreloss. Controlling geological dilution at the production stage: In production, thousands of meters of percussion holes are drilled annually for blasting purposes. However, since no core is recovered in this drilling process, information about the ore-waste contact is seldom acquired. Thus, there is the potential to geophysically log production holes to identify the ore-waste contact for optimal blast design with a resulting reduction in dilution and oreloss. Interpreting crosshole geophysics tomograms: By geophysically logging boreholes that were used in a crosshole geophysics survey, relationships can be developed to correlate logged geology and geophysical properties along the boreholes. These relationships could then be used in the interpretation of crosshole tomograms. The objectives are detection of undiscovered lenses and defining "connectivity" by mapping ore contours between delineation drillholes. Through analysis of data acquired during field tests at Louvicourt Mine operated by Aur Resources Inc. in northern Quebec, the potential of these applications of geophysical logging for dilution control in mining are examined.

Konferensbidrag (refereegranskat)abstract
- We show how most of the parameters of a DFB laser can be extracted from a limited number of relatively simple measurements. These measurements include the ASE spectra at different currents below threshold, the RIN spectra above threshold and the P-I relation. We have performed curve-fitting on different characteristics such as the ASE spectrum, the RIN spectrum and the P-I curve. From the ASE spectrum measured in the vicinity of the lasing wavelength we can extract grating parameters, facet phases, refractive index and gain as well as the wavelength and current dependence of the last two parameters
