In this paper, we study the general problem of similarity search in time series databases and we propose a novel multiresolution indexing (i.e., representation) and retrieval method for time series similarity search. Our approach is motivated by the idea that if we examine a time series at different resolution levels, we could possibly acquire further insights about the data. The proposed algorithm adopts a combined, two-step pruning (filtering) strategy to further reduce data dimensionality by discarding irrelevant time series (i.e., false alarms). At a first level, the time series are represented by line segments and filtered by the triangular inequality property. Then, a Vector Quantization like scheme is applied to encode data and thus to reduce dimensionality.\u0000 We test and demonstrate the performance of the proposed method, analyzing EEG time series data for retrieval of one of the constituent brain waveforms in EEG recordings, the K-complex, but the method can as well be applied for retrieval of other patterns of interest in time series analysis. The automatic detection and categorization of the EEG patterns will allow the advanced correlation analysis of large amounts of data and will lead to advanced decision making capabilities assisting diagnosis by medical professionals.","PeriodicalId":91811,"journal":{"name":"The ...

At the same time the demand for manual assembly grows. Assistive systems in production environments (ASiPE) have to be augmented to improve the overall performance and reduce skill requirements.\u0000 In this study the prototype of an augmented ASiPE is applied in an experiment with impaired persons. It uses in-situ projection (i.e. the projection of work-relevant information directly into the working space, Figures 1, 8) to cognitively assist users in assembly and to improve their inclusion in regular work processes. The aim is to observe their behavior with this new form of human computer interaction and to empirically quantify the effects on performance both in time and quality.\u0000 The results show that the augmentation has a catalytic effect: The test subjects assembling slowly could not cope with the augmented ASiPE and performed worse than their counterparts without augmentation. The test subjects who worked faster than average assembled the product significantly better, both with respect to time (14.5% reduction) and especially to quality (45.8% error reduction). The ability to access the potential of augmented workplaces seems to be related to a worker' cognitive potential which is not adequately mapped by the competence ratios sheltered work organizations currently use.","PeriodicalId":91811,"journal":{"name":"The ...

Recent advances in health related technologies as well as new modes of patient/provider interaction have created a unique set of novel challenges. Patients often face the daunting task of sifting through large amounts of options when it comes to choosing a medical service provider to receive care from. Several factors including the availability, cost, quality, and physical location of specific services must all be considered by the patient when choosing a provider. In this paper we describe a novel mobile application that allows users to query a database of medical providers to find the set of best possible options tailored to the user's specific needs and situation. The user makes a query by specifying a geographic search range centered on a polyline, and can further filter results by defining constraints such as insurance coverage and treatment cost.","PeriodicalId":91811,"journal":{"name":"The ...

CP limits a person's muscular function. Rehabilitative, touch-screen gaming promises to assist in developing muscle tone and dexterity for hemi-paretic CP patients as well as help therapists keep track of a patient's performance over time. However, most systems fail to take into account other factors of the disorder that could affect the scoring of a patient differently on various assessment days - specifically attention deficit or distraction. Cerebral Palsy is frequently associated with diagnosed Attention Deficit (Hyperactive) Disorder (ADD/ADHD), but even if a child does not fall within that definition, pediatric CP patients are often easily distracted. In this work we perform attention deficit simulation experiments with able-bodied users playing three rehabilitative games as well as similar computer generated data and propose a methodology to model and eliminate the effects of attention deficit or distraction from the scoring scheme used to evaluate the patient's motor abilities and progress over time.","PeriodicalId":91811,"journal":{"name":"The ...
