Exercise Performance Measurement with Smartphone Embedded Sensor for Well-Being Management

Regular physical activity reduces the risk of many diseases and improves physical and mental health. However, physical inactivity is widespread globally. Improving physical activity levels is a global concern in well-being management. Exercise performance measurement systems have the potential to improve physical activity by providing feedback and motivation to users. We propose an exercise performance measurement system for well-being management that is based on the accumulated activity effective index (AAEI) and incorporates a smartphone-embedded sensor. The proposed system generates a numeric index that is based on users’ exercise performance: their level of physical activity and number of days spent exercising. The AAEI presents a clear number that can serve as a useful feedback and goal-setting tool. We implemented the exercise performance measurement system by using a smartphone and conducted experiments to assess the feasibility of the system and investigated the user experience. We recruited 17 participants for validating the feasibility of the measurement system and a total of 35 participants for investigating the user experience. The exercise performance measurement system showed an overall precision of 88% in activity level estimation. Users provided positive feedback about their experience with the exercise performance measurement system. The proposed system is feasible and has a positive effective on well-being management.
The ICSI RT-09 Speaker Diarization System

The speaker diarization system developed at the International Computer Science Institute (ICSI) has played a prominent role in the speaker diarization community, and many researchers in the rich transcription community have adopted methods and techniques developed for the ICSI speaker diarization engine. Although there have been many related publications over the years, previous articles only presented changes and improvements rather than a description of the full system. Attempting to replicate the ICSI speaker diarization system as a complete entity would require an extensive literature review, and might ultimately fail due to component description version mismatches. This paper therefore presents the first full conceptual description of the ICSI speaker diarization system as presented to the National Institute of Standards Technology Rich Transcription 2009 (NIST RT-09) evaluation, which consists of online and offline subsystems, multi-stream and single-stream implementations, and audio and audio-visual approaches. Some of the components, such as the online system, have not been previously described. The paper also includes all necessary preprocessing steps, such as Wiener filtering, speech activity detection and beamforming.
The inherent complexity of dynamic data structures which accommodate range queries

A formal framework is presented in which to explore the complexity issues of data structures which accommodate various types of range queries. Within this framework, a systematic and reasonably tractable method for assessing inherent complexity is developed. Included among the interesting results are the following: the fact that non-linear lower bounds are readily accessible, and the existence of a complexity gap between linear time and n log n time.

Well-posednesss of strongly dispersive two-dimensional surface waves Boussinesq systems

We consider in this paper the well-posedness for the Cauchy problem associated to two-dimensional dispersive systems of Boussinesq type which model weakly nonlinear long wave surface waves. We emphasize the case of the {\it strongly dispersive} ones with focus on the "KdV-KdV" system which possesses the strongest dispersive properties and which is a vector two-dimensional extension of the classical KdV equation.
Facile Bench-Top Fabrication of Enclosed Circular Microchannels Provides 3D Confined Structure for Growth of Prostate Epithelial Cells

We present a simple bench-top method to fabricate enclosed circular channels for biological experiments. Fabricating the channels takes less than 2 hours by using glass capillaries of various diameters (from 100 µm up to 400 µm) as a mould in PDMS. The inner surface of microchannels prepared in this way was coated with a thin membrane of either Matrigel or a layer-by-layer polyelectrolyte to control cellular adhesion. The microchannels were then used as scaffolds for 3D-confined epithelial cell culture. To show that our device can be used with several epithelial cell types from exocrine glandular tissues, we performed our biological studies on adherent epithelial prostate cells (non-malignant RWPE-1 and invasive PC3) and also on breast (non-malignant MCF10A) cells We observed that in static conditions cells adhere and proliferate to form a confluent layer in channels of 150 µm in diameter and larger, whereas cellular viability decreases with decreasing diameter of the channel. Matrigel and PSS (poly (sodium 4-styrenesulphonate)) promote cell adhesion, whereas the cell proliferation rate was reduced on the PAH (poly (allylamine hydrochloride))-terminated surface. Moreover infusing channels with a continuous flow did not induce any cellular detachment. Our system is designed to simply grow cells in a microchannel structure and could be easily fabricated in any biological laboratory. It offers opportunities to grow epithelial cells that support the formation of a light. This system could be eventually used, for example, to collect cellular secretions, or study cell responses to graduated hypoxia conditions, to chemicals (drugs, siRNA, …) and/or physiological shear stress.
The visual control of landing and obstacle avoidance in the fruit fly Drosophila melanogaster

SUMMARY Landing behavior is one of the most critical, yet least studied, aspects of insect flight. In order to land safely, an insect must recognize a visual feature, navigate towards it, decelerate, and extend its legs in preparation for touchdown. Although previous studies have focused on the visual stimuli that trigger these different components, the complete sequence has not been systematically studied in a free-flying animal. Using a real-time 3D tracking system in conjunction with high speed digital imaging, we were able to capture the landing sequences of fruit flies (Drosophila melanogaster) from the moment they first steered toward a visual target, to the point of touchdown. This analysis was made possible by a custom-built feedback system that actively maintained the fly in the focus of the high speed camera. The results suggest that landing is composed of three distinct behavioral modules. First, a fly actively turns towards a stationary target via a directed body saccade. Next, it begins to decelerate at a point determined by both the size of the visual target and its rate of expansion on the retina. Finally, the fly extends its legs when the visual target reaches a threshold retinal size of approximately 60 deg. Our data also let us compare landing sequences with flight trajectories that, although initially directed toward a visual target, did not result in landing. In these ‘fly-by’ trajectories, flies steer toward the target but then exhibit a targeted aversive saccade when the target subtends a retinal size of approximately 33 deg. Collectively, the results provide insight into the organization of sensorimotor modules that underlie the landing and search behaviors of insects.
An Improved Hierarchical WLAN Positioning Method Based on Apriori Knowledge

The hierarchical-based structure is recognized as a favorable structure for wireless local area network (WLAN) positioning. It is comprised of two positioning phases: the coarse localization phase and the fine localization phase. In the coarse localization phase, the users’ positions are firstly narrowed down to smaller regions or clusters. Then, a fingerprint matching algorithm is adopted to estimate the users’ positions within the clusters during the fine localization phase. Currently the clustering strategies in the coarse localization phase can be divided into received signal strength (RSS) clustering and 3D clustering. And the commonly seen positioning algorithms in the fine localization phase include k nearest neighbors (kNN), kernel based and compressive sensing-based. This paper proposed an improved WLAN positioning method using the combination: 3D clustering for the coarse localization phase and the compressive sensing-based fine localization. The method have three favorable features: (1) By using the previously estimated positions to define the sub-reference fingerprinting map (RFM) in the first coarse localization phase, the method can adopt the prior information that the users’ positions are continuous during walking to improve positioning accuracy. (2) The compressive sensing theory is adopted in the fine localization phase, where the positioning problem is transformed to a signal reconstruction problem. This again can improve the positioning accuracy. (3) The second coarse localization phase is added to avoid the global fingerprint matching in traditional 3D clustering-based methods when the stuck-in-small-area problem is encountered, thus, sufficiently lowered the maximum positioning latency. The proposed improved hierarchical WLAN positioning method is compared with two traditional methods during the experiments section. The resulting positioning accuracy and positioning latency have shown that the performance of the proposed method has better performance in both aspects.
Self-Lensing by a Stellar Disk

I derive a general expression for the optical depth $\tau$ for gravitational lensing of stars in a disk by Massive Compact Objects (Machos) in the same disk. For the more restricted case where the disk is self-gravitating and the stars and Machos have the same distribution function, I find $\tau = 2\VEV{v^2}/c^2\sec^2 i$ where $\VEV{v^2}$ is the mass-weighted vertical velocity dispersion, and $i$ is the angle of inclination. This result does not depend on any assumptions about the velocity distribution. As an example, if stars within the bar of the Large Magellanic Cloud (LMC) account for the observed optical depth $\tau\sim 8\times 10^{-8}$ as has recently been suggested, then $v\gsim 60\,\kms$. This is substantially larger than the measured dispersions of known LMC populations.
Verb-particle constructions in a computational grammar of English

In this paper we investigate the phenomenon of verb-particle constructions, discussing their characteristics and the challenges that they present for a computational grammar. We concentrate our discussion on the treatment adopted in a wide-coverage HPSG grammar: the LinGO ERG. Given the constantly growing number of verb-particle combinations, possible ways of extending this treatment are investigated, taking into account the regular patterns found in some productive combinations of verbs and particles. We analyse possible ways of identifying regular patterns using different resources. One possible way to try to capture these is by means of lexical rules, and we discuss the difficulties encountered when adopting such an approach. We also investigate how to restrict the productivity of lexical rules to deal with subregularities and exceptions to the patterns found.
Use of Multi-Phase Stability Intervals to handle Crosstalk with the Timing Analyzer

This paper presents techniques to include the impact of crosstalk on timing verification of VLSI. We propose delay models for the victim driver gate, loaded through a resistive wire, when noise is injected from aggressor nets. A special care has been taken in order to minimize CPU time and data storage size. The proposed method was implemented with the hierarchical timing analyzer HiTAS and the stability analyzer STB by Avertec, a spin-off company of UPMC. Results on three real circuits are presented to illustrate the method.
Exploring similarities and differences in hospital adverse event rates between Norway and Sweden using Global Trigger Tool

Objectives In this paper, we explore similarities and differences in hospital adverse event (AE) rates between Norway and Sweden by reviewing medical records with the Global Trigger Tool (GTT). Design All acute care hospitals in both countries performed medical record reviews, except one in Norway. Records were randomly selected from all eligible admissions in 2013. Eligible admissions were patients 18 years of age or older, undergoing care with an in-hospital stay of at least 24 hours, excluding psychiatric and care and rehabilitation. Reviews were done according to GTT methodology. Setting Similar contexts for healthcare and similar socioeconomic and demographic characteristics have inspired the Nordic countries to exchange experiences from measuring and monitoring quality and patient safety in healthcare. The co-operation has promoted the use of GTT to monitor national and local rates of AEs in hospital care. Participants 10 986 medical records were reviewed in Norway and 19 141 medical records in Sweden. Results No significant difference between overall AE rates was found between the two countries. The rate was 13.0% (95% CI 11.7% to 14.3%) in Norway and 14.4% (95% CI 12.6% to 16.3%) in Sweden. There were significantly higher AE rates of surgical complications in Norwegian hospitals compared with Swedish hospitals. Swedish hospitals had significantly higher rates of pressure ulcers, falls and ‘other’ AEs. Among more severe AEs, Norwegian hospitals had significantly higher rates of surgical complications than Swedish hospitals. Swedish hospitals had significantly higher rates of postpartum AEs. Conclusions The level of patient safety in acute care hospitals, as assessed by GTT, was essentially the same in both countries. The differences between the countries in the rates of several types of AEs provide new incentives for Norwegian and Swedish governing bodies to address patient safety issues.
STUDIES ON EPITHELIAL CELLS ISOLATED FROM GUINEA PIG SMALL INTESTINE

Sheets of mucosal epithelial cells were released from guinea pig small intestine after incubation with ethylenediaminetetraacetate. Cells in sheets retained their columnar shape for 24 hr at room temperature, and exclusion of nigrosine suggested they had intact plasma membranes. When sheets were disaggregated individual cells had normal morphology for at least 4 hr. During isolation 16% of the total protein and 24% of the total lactic dehydrogenase were lost from the cells, but subsequent enzyme leakage was low. Leakage increased with shaking, incubation at 37°C, or increasing the oxygen tension of the suspending medium, but was minimal when the Na+:K+ ratio in the medium was 8:1 and the osmolarity was high. Losses of particulate enzyme activities were negligible. Respiration was constant for up to 4 hr and was insensitive to calcium, bicarbonate, oxygen tension, and pH. It was inhibited by cyanide and iodoacetate and varied with the Na+:K+ ratio of the extracellular fluid and the structural integrity of the cells. All preparations concentrated potassium and excluded sodium, but lost this ability if ouabain was added or cells were broken. Potassium-42 uptake was also sensitive to temperature, ouabain, and structural integrity. The preparations are being used to study cell metabolism in the intestinal epithelium.
Can direct manipulation lower the barriers to computer programming and promote transfer of training?: An experimental study

Novices face many barriers when learning to program a computer, including the need to learn both a new syntax and a model of computation. By constraining syntax and providing concrete visual representations on which to operate, direct manipulation programming environments can potentially lower these barriers. However, what if the ultimate learning goal of the novice is to be able to program in conventional textual languages, as is the case for introductory computer science students? Can direct manipulation programming environments lower the initial barriers to programming, and, at the same time, facilitate positive transfer to textual programming? To address this question, we designed a new direct manipulation programming interface for novices, and conducted an experimental study to compare the programming processes and outcomes promoted by the direct manipulation interface against those promoted by a textual programming interface. We found that the direct manipulation interface promoted significantly better initial programming outcomes, positive transfer to the textual interface, and significant differences in programming processes. Our results show that direct manipulation interfaces can provide novices with a “way in” to traditional textual programming.
A review on steganography through multimedia

Steganography is a type of secrete communication that hides the secrete information. It deals with the different ways of hiding/embedding the secrete information such as text, image, audio or video files inside another multimedia files with the help of private key. The hidden information is termed as secrete file and the file in which the secrete file is hidden is termed as cover file. The file represents the multimedia files such as text, image, audio or video. The obtained embedded file is said to be stego file. In this paper, the various steganographic techniques used for hiding the secrete file inside the cover file have been discussed.
Data Anonymization Approach For Privacy Preserving In Cloud

Private data such as electronic health records and banking transactions must be shared within the cloud environment to analysis or mine data for research purposes. Data privacy is one of the most concerned issues in big data applications, because processing large-scale sensitive data sets often requires computation power provided by public cloud services. A technique called Data Anonymization, the privacy of an individual can be preserved while aggregate information is shared for mining purposes. Data Anonymization is a concept of hiding sensitive data items of the data owner. A bottom-up generalization approach for transforming more specific data to less specific but semantically consistent data in order to preserve privacy. The idea is to explore the data generalization from data mining to hide detailed data, rather than discovering the patterns. When the data is masked, data mining techniques can be applied without modification. Keywords—Data Anonymization; Cloud; Bottom Up Generalization; Mapreduce; Privacy Preservation.
Clustering Social Images with MapReduce and High Performance Collective Communication

Social Image clustering is a data intensive application that provides novel challenges to high performance computing. Already this field has reached 10-100 million images represented as points in a high dimensional (up to 2048) vector space that are to be divided into up to 1-10 million clusters. In recent years MapReduce has become popular in processing big data problems due to its attractive programming interface with scalability and reliability. However, because social image clustering is an iterative data mining application, the performance of traditional MapReduce frameworks is poor on this problem due to the overhead of repeated disk access. By caching invariant data between iterations into local memory on each node, our Twister system is able to accelerate MapReduce iterations. In each iteration, data is processed through 5 stages: Broadcast, Map, Shuffle, Reduce and Combine and this paper focuses on the four collective communication stages where the large data sizes allow and demand performance optimization where we combine ideas from the MapReduce and MPI communities. We present detailed analysis of the division of 7 million image feature vectors in 512 dimensions into 1 million clusters, executing the application on 1000 cores (125 nodes each of which has 8 cores) with 10000 Map tasks and 125 Reduce tasks. Particular challenges are the 20TB of intermediate data generated in the shuffling stage and 512MB of data to be broadcast. We compare several approaches to broadcasting showing that a topology-aware and pipeline-based method gives improved performance of a factor of 120 compared to simple method; a factor of 5 compared to basic pipelined methods and a factor 1.2 compared to MPI. Further we add a local reduction stage before the shuffle which reduces the 20 TB intermediate data to “just” 250 GB. We discuss the next steps that will scale to larger problems and introduce new algorithms that will speed up the map stage by one to two orders of magnitude and highlight need for high performance collectives developed in this paper.
Liberalism against the people: learning to live with coups d’état

ABSTRACT This article argues that a perceived liberal ‘defection’ to a 2006 military coup in Thailand can help illuminate the authoritarian face of liberalism during an existential crisis; more provisionally, it is proposed that the Thai experience may provide lessons for understanding liberal decisionism. Detailing a single case has the advantage of embedding the discussion in cultural, historical and political detail without which the action is incomprehensible. The article applies decisionist and morphological theory and historical analysis as it explores the factors and motives leading to liberal coup complicity. The article’s chief objective is to make intelligible a form of liberal extra-constitutional decisionism in a non-western setting.
