Feature selection for elderly faller classification based on wearable sensors
No full textAbstract Background Wearable sensors can be used to derive numerous gait pattern features for elderly fall risk and faller classification; however, an appropriate feature set is required to avoid high computational costs and the inclusion of irrelevant features. The objectives of this study were to identify and evaluate smaller feature sets for faller classification from large feature sets derived from wearable accelerometer and pressure-sensing insole gait data. Methods A convenience sample of 100 older adults (75.5 ± 6.7 years; 76 non-fallers, 24 fallers based on 6 month retrospective fall occurrence) walked 7.62 m while wearing pressure-sensing insoles and tri-axial accelerometers at the head, pelvis, left and right shanks. Feature selection was performed using correlation-based feature selection (CFS), fast correlation based filter (FCBF), and Relief-F algorithms. Faller classification was performed using multi-layer perceptron neural network, naïve Bayesian, and support vector machine classifiers, with 75:25 single stratified holdout and repeated random sampling. Results The best performing model was a support vector machine with 78% accuracy, 26% sensitivity, 95% specificity, 0.36 F1 score, and 0.31 MCC and one posterior pelvis accelerometer input feature (left acceleration standard deviation). The second best model achieved better sensitivity (44%) and used a support vector machine with 74% accuracy, 83% specificity, 0.44 F1 score, and 0.29 MCC. This model had ten input features: maximum, mean and standard deviation posterior acceleration; maximum, mean and standard deviation anterior acceleration; mean superior acceleration; and three impulse features. The best multi-sensor model sensitivity (56%) was achieved using posterior pelvis and both shank accelerometers and a naïve Bayesian classifier. The best single-sensor model sensitivity (41%) was achieved using the posterior pelvis accelerometer and a naïve Bayesian classifier. Conclusions Feature selection provided models with smaller feature sets and improved faller classification compared to faller classification without feature selection. CFS and FCBF provided the best feature subset (one posterior pelvis accelerometer feature) for faller classification. However, better sensitivity was achieved by the second best model based on a Relief-F feature subset with three pressure-sensing insole features and seven head accelerometer features. Feature selection should be considered as an important step in faller classification using wearable sensors
Tracking system, arrangement and method for tracking objects
No full textA tracking system for tracking objects within a field of view is disclosed. The field of view may include a first zone and an adjacent zone of interest where at least two gates are associated with respective sides of the first zone within the field of view. The first camera is configured to detect when an object crosses one of the at least two gates and track the object throughout the first zone and the zone of interest. The tracking system is configured to generate a first event message in response to the object being tracked from one of the gates into the zone of interest and subsequently leaving the first zone through a dedicated gate of the at least two gates

No full texttracking system for tracking objects within a field of view is proposed. The field of view includes a first zone (A1) and an adjacent zone (A0) of interest, wherein at least two gates (G1, G2) are associated with respective sides of the first zone (A1) within the field of view. The first camera (C1) is adapted to detect when an object crosses one of the at least two gates and track the object throughout the first zone (A1) and the zone (A0) of interest; wherein the tracking system is adapted to generate a first event message (ES1) in response to the object being tracked from one of the gates into the zone (A0) of interest and subsequently leaving the first zone through a dedicated gate (G1) of the at least two gates
Revisiting the pro-oxidant activity of copper: Interplay of ascorbate, cysteine, and glutathione
Get PDFCopper (Cu) is essential for most organisms, but it can be poisonous in excess, through mechanisms such as protein aggregation, trans-metallation, and oxidative stress. The latter could implicate the formation of potentially harmful reactive oxygen species (O-2(& BULL;)-, H2O2, and HO & BULL;) via the redox cycling between Cu(II)/Cu(I) states in the presence of dioxygen and physiological reducing agents such as ascorbate (AscH), cysteine (Cys), and the tripeptide glutathione (GSH). Although the reactivity of Cu with these reductants has been previously investigated, the reactions taking place in a more physiologically relevant mixture of these biomolecules are not known. Hence, we report here on the reactivity of Cu with binary and ternary mixtures of AscH, Cys, and GSH. By measuring AscH and thiol oxidation, as well as HO & BULL; formation, we show that Cu reacts preferentially with GSH and Cys, halting AscH oxidation and also HO & BULL; release. This could be explained by the formation of Cu-thiolate clusters with both GSH and, as we first demonstrate here, Cys. Moreover, we observed a remarkable acceleration of Cu-catalyzed GSH oxidation in the presence of Cys. We provide evidence that both thiol-disulfide exchange and the generated H2O2 contribute to this effect. Based on these findings, we speculate that Cu-induced oxidative stress may be mainly driven by GSH depletion and/or protein disulfide formation rather than by HO & BULL; and envision a synergistic effect of Cys on Cu toxicity
Byte av kommunikationsstrategi när nationsobligatoriet faller : En fallstudie av hur nationerna i Uppsala bör agera om nationsobligatoriet faller
No full textAbstract Title: Change of communication strategy when the compulsory nation membership falls (Byte av kommunikationsstrategi när nationsobligatoriet faller) Number of pages: 51 (58 including enclosures) Author: Elin Rantakokko Tutor: Peder Hård af Segerstad Course: Media and Communication Studies 30 hp Period: Spring of 2008 University: Division of Media and Communication, Department of Information Science, Uppsala University Purpose/Aim: This essay will result in some guidelines how the nations in Uppsala can act if the law according the compulsory membership in the student union and the student nations change. This essay focuses on how the nations can communicate to keep their members. Material/method: I have done seven interviews with persons that work in three different nations and the head of the Curators convent (the collaboration center between the nations), I have read articles from the largest newspapers and web pages. I have also read the Commission of Inquiry's recommendation according abolishing the law regarding the compulsory nation and student union membership. I have created two scenarios based on the material, according to Peter Schwartz advises. Main results: These scenarios show that the student nations have to become better at communicating with their new members and their already existing members. Keywords: Scenario planning, marketing, communication, student union, student nation, market segmentation, strategic communication, profile, organizations change

Functional task kinematics in older adults: the role of fear of falling and fall history as measured by themovement deviation profile
No full textBackground: Most falls at home of older adults occur during activities of daily living, with fear of falling (FOF) heightening the risk. Research question: How does the fear of falling influence the kinematics of functional tasks in faller and non-faller older people? Methods: A total of 68 participants aged 60 and older were divided into four groups: NF-lowFOF (non-faller with low fear, control group), NF-highFOF (non-faller with high fear), F-lowFOF (faller with low fear), and F-highFOF (faller with high fear), with 17 individuals in each group. The three-dimensional kinematics data were analyzed using a single number gait deviation index, the mean Movement Deviation Profile (MDPmean), to identify which task and group had the greatest difference by comparing the Z-scores of the MDPmean. Multivariate analysis and Bonferroni post hoc tests (p < 0.05) were employed to analyze group interactions. Results: Significant differences in kinematics were observed across all functional tasks. The largest effect size between the control group and the other groups for each functional task were descending and ascending stairs, sitting to stand, walking turn and gait in F-highFOF, and standing to sit in F-lowFOF. The time to perform each task didn't differ between the groups. Significance: FOF (whether high or low) can significantly impact the kinematics of functional tasks in both faller and non-faller older adults. Therefore, assessing FOF in this population is crucial to prevent falls and promote rehabilitation, especially in non-faller older adults with high FOF
