Wearable Devices Components for High Jump Sport: An Overview

: Wearable devices like FitBit, Garmin and Amazfit smartwatch have become popular in recent years. Athlete like swimmers and runners mostly use smartwatch to track speed of the swim or run using embedded global positioning system (GPS) sensor in the wearable devices. Unfortunately, high jump sports still on the old style in tracking the movement of the jump by using vision system. Thus, this paper presents an overview on related work, existing methods and developments on the area of wearable sensor for high jump sports. The analysis of high jump sports related works in terms of main injury and parameters to prevent the injury are being analysed. The used of biosensors in recent wearable devices has been also reviewed in term of the types and issues of sensor that need to implement in the wearable device. Other than that, the processing methods that contains Internet of Thing (IoT) gateway device, network transmission and real-time monitoring system (RtMS) are proposed to develop a complete wearable device. Finally, the main injury parameters of the high jump sports and sensors related to the parameter has been reviewed and an overall idea of processing method RtMS has been summarised.
Seismic performance of bamboo structures

This dissertation describes a wide-ranging research program aimed at identifying a methodthrough which vernacular bamboo construction methods may be formalized into a performancebased design framework. This requires an understanding of both material and structural behavior and an appreciation of the social and engineering context in which the structure is built. A relatively brief background and literature review addressing a number of topics relevant to the research methodology adopted in the present work including: sustainability, bamboo availability, properties and construction techniques, the hazard environment considered in this study and approaches to hazard mitigation and performance based design are presented.The prototype structure that is the focus of the dissertation is investigated in an experimental study to determine the prototype frame behavior. The behavior forms the basis for the analytical model developed in work. In the course of the research program it was determined that certain mechanical properties of bamboo are not well established and, furthermore, that thereis no standard method for comparing these critical properties. The work, therefore, reports on an experimental program aimed at filling these gaps in available knowledge and data. Initially afracture mechanics approach to quantifying bamboo behavior was attempted in an effort to normalize for the significant variation expected in a natural material. While this method was successful, it was not felt to be practical for application outside a well-equipped laboratoryenvironment. Thus a simpler, mechanics-based, materials test was pursued and an attempt tocorrelate results from this with the more reliable fracture mechanics approach was made. Afinite element model (FEM) of the prototype structure was developed. Static pushover andnonlinear dynamic analyses were conducted on several models of the prototype structure. Inaddition to the seismic model, the effect of the variability of bamboo material propertiesidentified in a statistical analysis of data collected by the Group for Non-Conventional Materials (GNOCMAT) at PUC-Rio and the author's group at the University of Pittsburgh was explored.
Regular Feedback on the Inter-Hospital Transfer Improved the Quality and Survival in Patients with Multiple Trauma: A Retrospective Cohort Study

Background: Under-triage of major trauma patients has been unavoidable, especially in the trauma system of rural area. Timely stabilization and transfer of critical trauma patients remains a great challenge for hospitals limited in resources for major trauma management. No definitive measure has been proved to improve the outcome of transferred major trauma patients. Current study hypothesized that regular feedback on inter-hospital transfer of patients with major trauma can improve care quality and outcome.Method: This retrospective cohort study retrieved the transferred trauma patients with injury severity score(ISS) ≥ 16 between Jan 2010 and Dec 2018 from the trauma registry databank of a tertiary medical center. Regular monthly feedback on inter-hospital transfer was initiated since 2014. The patients were divided into the without-feedback group and the with-feedback group. The demographic data, management before transfer, and outcome after transfer were collected and analyzed.Results: A total of 178 patients were included; 69 patients in the without-feedback and 109 in the with-feedback group. The with-feedback group had higher ISS (25 vs 27, p = 0.049), and more patients needing massive transfusion (14.49% vs 29.36%, p = 0.036). After adjusted for confounding factors, the with-feedback group was associated with higher rate of blood transfusion before transfer (adjusted odds ratio [aOR] 2.75, 95% CI [1.01-7.52], p = 0.049), shorter time span before blood transfusion (-31.80 ± 15.14, p = 0.038), and decreased mortality risk (aOR 0.33, 95% CI [0.13-0.83], p = 0.019). Conclusion: This retrospective cohort study revealed that regular feedback on inter-hospital transfer improved the quality of blood transfusion and was associated with decreased mortality risk.

Customers’ expectations factors in restaurants

This paper examines the attributes which influence customers’ decisions to return to a restaurant for another meal. The restaurant sector is one of the fastest growing sectors within the context of the Spanish economy and looks likely to continue its development into the future. The implementation of Total Quality (TQ) systems in the tourist industry is still a recent phenomenon in Spain. Hence the importance of the client’s satisfaction, resulting in the acquisition of an optimum quality level: i.e. cooking is culture and it has to be culturally adapted and promoted. The survey reported in this paper on the customers of Spanish restaurants has gathered the perception of quality according to a Likert scale from zero to ten. Male customers did not rate the attributes differently from female customers. Quality of food was rated as the most important attribute, followed by quality of service, cost/value of the meal, and place/ambience of the restaurant.
Xenografts in Periodontal Regeneration: A Viable Alternative

Periodontal disease is categorized by the destruction of periodontal tissues. Over the years, there have been several clinical techniques and material options that have been investigated for periodontal defect repair or regeneration. The development of improved biomaterials for periodontal tissue engineering has significantly upgraded the available treatment options and their clinical results. Bone replacement graft materials, barrier membranes, various growth factors and combination of these have been used. Autografts have been used as the bone graft material of choice since many years. But this type of grafts has many limitations to its use. In order to overcome its drawbacks, xenografts may be used as a viable alternative. Xenografts also known as heterologous graft tissues, is obtained from different species, and has been used in various different periodontal procedures. The characteristic properties of xenografts and the benefits of using it has made this type of graft to emerge as an appropriate choice for periodontal regeneration. The objective of this article is to a review xenograft as a bone replacement graft material to be used in periodontal therapy. The source, mode of bone regeneration and the respective advantages and disadvantages of xenogenic materials have been discussed in detail.
Longitudinal Employer-Household Dynamics

One of the most striking facts to emerge from the literature on displaced workers is the earnings declines experienced by workers several years before displacement occurs. Little attention, however, has been paid to other changes in compensation and employment in firms prior to the actual displacement event. This paper examines changes in the composition of job and worker flows before displacement, and compares the “quality” distribution of workers leaving distressed firms to that of all movers in general. More specifically, we exploit a unique dataset that contains observations on all workers over an extended period of time in a number of US states, combined with survey data, to decompose different jobflow statistics according to skill group and number of periods before displacement. Furthermore, we use quantile regression techniques to analyze changes in the skill profile of workers leaving distressed firms. Throughout the paper, our measure for worker skill is derived from person fixed effects estimated using the wage regression techniques pioneered by Abowd, Kramarz, and Margolis (1999) in conjunction with the standard specification for displaced worker studies (Jacobson, LaLonde, and Sullivan 1993). We find that there are significant changes to all measures of job and worker flows prior to displacement. In particular, churning rates increase for all skill groups, but retention rates drop for high-skilled workers. The quantile regressions reveal a right-shift in the distribution of worker quality at the time of displacement as compared to average firm exit flows. In the periods prior to displacement, the patterns are consistent with both discouraged high-skilled workers leaving the firm, and management actions to layoff low-skilled workers.

Investigation of premature distress around joints in PCC pavements

Some of the Indiana concrete pavements that have been constructed within the last 10 years have shown signs of premature deterioration, especially in the areas adjacent to the longitudinal joints. This deterioration typically manifests itself as cracking and spalling of concrete combined with the loss of joint sealant. These processes create a cavity in the joint area that traps water and, as a consequence, accelerates further deterioration of concrete during the freezing and thawing cycles. The objective of this study was to examine in details the microstructural and chemical changes in concrete extracted form the affected areas in an attempt to determine the cause of this premature deterioration. The investigation started with a detailed inventory of selected areas of affected pavements in order to identify and classify the existing types of distresses and select locations for collection of the cores. The cores have been collected from the following four locations: NB lines of I-65 near downtown Indianapolis, SR 933 near South Bend, Intersection of 86th Street and Payne Road in Indianapolis and a ramp from US67 to I-465E, also in Indianapolis. A total of thirty six 6-in. diameter cores were removed from pavements at these locations and transported to the laboratory where they were subjected to eight different tests: air-void system determination, Scanning Electronic Microscopy (SEM) analysis, X-ray diffraction (XRD) analysis, sorptivity test, freeze-thaw & resonance frequency test, resistance to chloride ion penetration (RCP) test and chloride profile (concentration) determination. The test results identified several cases of in-filling of the air voids (especially smaller air bubbles) with secondary deposits. These deposits were most likely the result of the repetitive saturation of air voids with water and substantially reduced the effectiveness of the air voids system with respect to providing an adequate level of freeze-thaw protection. In addition, the affected concrete often developed an extensive network of microcracks, showed higher rates of absorption and reduced ability to resist chloride ions penetration.
Crisis Strategies in the Sector of Knowledge-Intensive Services

The research continues the series devoted to the study of knowledge-intensive services (KIS) in Russia. The last but not the least round of it conducted in 2009 was dedicated to the trends provoked by the global economic crisis. Sales and employment in KIS sector decreased moderately, but the strategic vision of its actors was distorted. KIS producers reduced their strategic horizon to short run, and lost distinct dominating strategy. Current strategies are distinguished by the level of product diversification. Standard (“box”) services are supplied to inexperienced users. Partially customised services form the essence of a damping strategy aimed at more experienced users. Tailored (bespoke) services are the core of innovative strategy: its target group consists of competent consumers who recognise and appreciate KIS as product innovations.
Improving Ventilation and Saving Energy: Laboratory Study in aModular Classroom Test Bed

The primary goals of this research effort were to develop, evaluate, and demonstrate a practical HVAC system for classrooms that consistently provides classrooms with the quantity of ventilation in current minimum standards, while saving energy, and reducing HVAC-related noise levels. This research was motivated by several factors, including the public benefits of energy efficiency, evidence that many classrooms are under-ventilated, and public concerns about indoor environmental quality in classrooms. This project involved the installation and verification of the performance of an Improved Heat Pump Air Conditioning (IHPAC) system, and its comparison, a standard HVAC system having an efficiency of 10 SEER. The project included the verification of the physical characteristics suitable for direct replacement of existing 10 SEER systems, quantitative demonstration of improved energy efficiency, reduced acoustic noise levels, quantitative demonstration of improved ventilation control, and verification that the system would meet temperature control demands necessary for the thermal comfort of the occupants. Results showed that the IHPAC met these goals. The IHPAC was found to be a direct bolt-on replacement for the 10 SEER system. Calculated energy efficiency improvements based on many days of classroom cooling or heating showed that the IHPAC system is about 44% more efficient duringmore » cooling and 38% more efficient during heating than the 10 SEER system. Noise reduction was dramatic, with measured A-weighed sound level for fan only operation conditions of 34.3 dB(A), a reduction of 19 dB(A) compared to the 10 SEER system. Similarly, the IHPAC stage-1 and stage-2 compressor plus fan sound levels were 40.8 dB(A) and 42.7 dB(A), reductions of 14 and 13 dB(A), respectively. Thus, the IHPAC is 20 to 35 times quieter than the 10 SEER systems depending upon the operation mode. The IHPAC system met the ventilation requirements and was able to provide consistent outside air supply throughout the study. Indoor CO2 levels with simulated occupancy were maintained below 1000 ppm. Finally temperature settings were met and controlled accurately. The goals of the laboratory testing phase were met and this system is ready for further study in a field test of occupied classrooms. « less
Effect of blanching pre-treatment on colour and anthocyanin of dried slice purple sweet potato (Ipomoea batatas L)

Purple sweet potato (Ipomoea batatas L) contains many acylated anthocyanins which are beneficial for human health. Purple sweet potato roots are easily damaged due to the high water and nutrient content. To extend the shelf life of purple sweet potatoes can be done by a drying process. The drying process can affect the colour and amount of anthocyanin. The purpose of this study was to analyse the effect of blanching on colour and the amount of anthocyanin of dried slice purple sweet potato. The blanching method studied was steam blanching with a temperature of 70°C-80°C and blanch with boiling water 90°C – 98°C for 2 minutes. To measure the amount of anthocyanin by the pH difference method and measure colour using the chromameter. The results showed that the steam blanching technique produced a higher colour and amount of anthocyanin of dried chips purple sweet potato compared to blanching boiling water. This is because Anthocyanin dissolves in water. The conclusion is to get the colour and the relatively high amount of anthocyanin in dried pieces of purple sweet potato can be done by steam blanching. The implication to prevent browning process when making dried slice purple sweet potato can do steam blanching.
Heat Wave: A Social Autopsy of Disaster in Chicago

In July 1995, Chicagoans suffered through a blistering week-long heat wave that buckled streets and downed portions of the city's power grid. It also left over 700 people dead. In this alarming book, Eric Klinenberg tells us how such fatalities could have happened in a modern American city. The picture he paints - of social breakdown, unresponsive government and poorly equipped public services - is one no reader interested in the current state of American urbanism can afford to ignore.
Unitary ESPRIT algorithm for bistatic MIMO radar

A new Unitary ESPRIT algorithm for joint direction of departure (DOD) and direction of arrival (DOA) estimation in bistatic MIMO radar is proposed. The properties of centro-Hermitian matrices are utilised to transform the complex-valued data matrix into a real-valued data matrix. Then the real-valued rotational invariance equations for signal subsapce are figured out to estimate DOAs and DODs which are paired automatically in a new way. The proposed algorithm provides increased estimation accuracy with reduced computational complexity owing to real-valued processing and double the number of data samples inherently in unitary ESPRIT. Simulation results are presented to verify the effectiveness of the proposed algorithm.
Phonetic and Lexical Encoding of Tone in Cantonese Heritage Speakers

Heritage speakers contend with at least two languages: the less dominant first language (L1), that is, the heritage language, and the more dominant second language (L2). In some cases, their L1 and L2 bear striking phonological differences. In the current study, we investigate Toronto-born Cantonese heritage speakers and their maintenance of Cantonese lexical tone, a linguistic feature that is absent from English, the more dominant L2. Across two experiments, Cantonese heritage speakers were tested on their phonetic/phonological and lexical encoding of tone in Cantonese. Experiment 1 was an AX discrimination task with varying inter-stimulus intervals (ISIs), which revealed that heritage speakers discriminated tone pairs with disparate pitch contours better than those with shared pitch contours. Experiment 2 was a medium-term repetition priming experiment, designed to extend the findings of Experiment 1 by examining tone representations at the lexical level. We observed a positive correlation between English dominance and priming in tone minimal pairs that shared contours. Thus, while increased English dominance does not affect heritage speakers’ phonological-level representations, tasks that require lexical access suggest that heritage Cantonese speakers may not robustly and fully distinctively encode Cantonese tone in lexical memory.
A Systems Analysis and Design Semester Project: A Stand-alone Project vs. a Competitive Project

Numerous educators have suggested and shown the value in having a real world project for a Systems Analysis and Design course. These real projects are often structured as semester group projects. Traditionally I have had each group work on a different client system. I changed this project structure when an opportunity presented itself to have students complete projects on the same client in more of a competitive environment, similar to an organization soliciting bids on analyzing and designing a new system. At the end of the semester, based on both student comments and the final deliverables, I concluded that there are definite pros and cons of having stand-alone vs. a competitive semester project. However, if I had to choose one, I would have students complete competitive semester projects as experience led me to believe that overall outcomes are better and more positive.
Polarization Effects on the Non-Linearity of a Highly Non-Linear Fiber

Abstract The effective non-linear parameter of a highly non-linear optical fiber was measured using the four-wave mixing effect. A value of γ = 10.6 W–1/km was obtained for a small wavelength separation between pump and signal waves, whereas for a large wavelength separation, a value of = 8γ/9 = 9.4 W–1/km was found. This value corresponds to an average of the Kerr non-linearity over the Poincaré sphere, since the polarization of both the pump and signal waves become uncorrelated in the last case. A theoretical model is proposed to describe the variation of the effective non-linear parameter with the wavelength separation between pump and signal waves, which is in good agreement with the experimental data.
Subtyping Salmonella of Pet Dogs With Multilocus Sequence Typing (MLST) and Clustered Regularly Interspaced Short Palindromic Repeats (CRISPRs)

Salmonella, as a zoonotic pathogen, has attracted widespread attention worldwide, especially in the transmission between household pets and humans. Therefore, we investigated the epidemic distribution of dog Salmonella from pet hospitals and breeding base in Xuzhou, Jiangsu Province, China, and used multilocus sequence typing（MLST）and clustered regularly interspaced short palindromic repeats（CRISPRs）to subtype Salmonella isolates. From April 2018 to November 2019, a total of 469 samples were collected from pet hospitals and breeding base, including 339 dog samples and 60 cat samples. S. Kentucky (40.74%) was the most prevalent serotype, but other, such as S. Typhimurium (18.52%) and S. Indiana (18.52%), were also widespread. Eight different sequence type (ST) patterns were Identified by MLST and ST198 was the highest proportion of these isolates. CRISPRs analysis showed that 9 different Kentucky CRISPR types (KCTs) was identified from ST198. 48 spacers including 29 (6 News) for CRISPR1 and 19 (4 News) for CRISPR2 that proved the polymorphic of Salmonella genes in samples from different sources. The analysis demonstrated that the common serotypes were widely present in pet hosts in the same area. This analysis shows that CRISPR genes have better recognition ability in the same serotype, which has a positive effect on the traceability of salmonella and the prevention and treatment of salmonellosis.
