Abstract:

Measurement of the sleeping state is useful for monitoring the health of a person being nursed. The sleeping state can be estimated from biological information such as respiration rate, heart rate, body motion, and lying posture. A heart rate measurement method that considers the harmonics of a respiratory signal is described herein. The harmonics of respiratory signals for heart rate measurement has not been considered hitherto. An unconstrained method is proposed for measuring respiration, heart rate, and lying posture using a Smart Rubber sensor, which is a rubber-based flexible planar tactile sensor developed for this study. Respiration and heart rates are measured by applying frequency analysis to time-series data of body pressure. The harmonics of a respiratory signal serves as noise in heart rate measurement. Therefore, the heart rate measurement is improved by eliminating the effects of harmonics. The average frequency error of the heart rate measurement by our proposed method is 0.144 Hz. Experimental results show that our proposed method enhances the precision of heart rate measurement. Hence, this method enables the accurate measurement of the sleeping state.

Abstract:

This paper presents compact design and implementation of a portable device for application of continuous Electrocardiogram(ECG) and respiration measurement in the field of dynamic health monitoring. Bluetooth technique is used for data transmission between portable device and acquisition node such as computer or smart phone, given its advantages of low power consumption and easy wireless connection. The device also includes a wireless power module for charging the lithium polymer battery with the charging current up to 300mA, which makes power supply much more conveniently. Measurement of ECG and respiration is implemented by two electrodes layout solution and ADS1292R which enable the system design at significantly reduced size(60mm*40mm), power, and overall cost. Experiments are carried out with appropriate work parameters as sample rates and resolution. The results show that our device can accurately acquire the ECG and multiple respiration states..

Abstract:

Abstract Aims/hypothesis Obesity during pregnancy increases offspring type 2 diabetes risk. Given that nearly half of women of child-bearing age in many populations are currently overweight/obese, it is key that we improve our understanding of the impact of the in utero/early life environment on offspring islet function. Whilst a number of experimental studies have examined the effect of maternal obesity on offspring islet architecture and/or function, it has not previously been delineated whether these changes are independent of other confounding risk factors such as obesity, postnatal high-fat-feeding and ageing. Thus, we aimed to study the impact of exposure to maternal obesity on offspring islets in young, glucose-tolerant male and female offspring. Methods Female C57BL/6J mice were fed ad libitum either chow or obesogenic diet prior to and throughout pregnancy and lactation. Offspring were weaned onto a chow diet and remained on this diet until the end of the study. An IPGTT was performed on male and female offspring at 7 weeks of age. At 8 weeks of age, pancreatic islets were isolated from offspring for measurement of insulin secretion and content, mitochondrial respiration, ATP content, reactive oxygen species levels, beta and alpha cell mass, granule and mitochondrial density (by transmission electron microscopy), and mRNA and protein expression by real-time RT-PCR and Western blotting, respectively. Results Glucose tolerance was similar irrespective of maternal diet and offspring sex. However, blood glucose was lower (p < 0.001) and plasma insulin higher (p < 0.05) in female offspring of obese dams 15 min after glucose administration. This was associated with higher glucose- (p < 0.01) and leucine/glutamine-stimulated (p < 0.05) insulin secretion in these offspring. Furthermore, there was increased mitochondrial respiration (p < 0.01) and density (p < 0.05) in female offspring of obese dams compared with same-sex controls. Expression of mitochondrial and nuclear-encoded components of the electron transport chain, L-type Ca2+ channel subtypes that play a key role in stimulus-secretion coupling [Cacna1d (p < 0.05)], and oestrogen receptor α (p < 0.05) was also increased in islets from these female offspring of obese dams. Moreover, cleaved caspase-3 expression and BAX:Bcl-2 were decreased (p < 0.05) reflecting reduced susceptibility to apoptosis. In contrast, in male offspring, glucose and leucine/glutamine-stimulated insulin secretion was comparable between treatment groups. There was, however, compromised mitochondrial respiration characterised by decreased ATP synthesis-driven respiration (p < 0.05) and increased uncoupled respiration (p < 0.01), reduced docked insulin granules (p < 0.001), decreased Cacna1c (p < 0.001) and Cacna1d (p < 0.001) and increased cleaved caspase-3 expression (p < 0.05). Conclusions/interpretation Maternal obesity programs sex differences in offspring islet function. Islets of female but not male offspring appear to be primed to cope with a nutritionally-rich postnatal environment, which may reflect differences in future type 2 diabetes risk.

Abstract:

In the era of the development of computer technology, methods were created that enable teaching, not only through direct contact with the student, but also through the computer network and the Internet. In order for this to be possible, programs allowing this type of activity had to be created. They are to model the operating conditions of electronic and measurement systems in virtual space as much as possible. Such programs must reflect the operation of such systems under operating conditions, taking into account disturbing signals. They should also be adapted to remote work via the Internet. In the era of epidemics, when the possibilities of teaching in the classical form are very limited or impossible, simulation programs working in a network environment may make sense. The results of modeling the operation of systems in virtual reality and the created measurement systems can be sent electronically. This allows their verification with the laboratory teacher and joint work on the project by a group of students during the laboratory classes.

Abstract:

Recent critiques of and research with traditional alcohol prevention programs have revealed serious problems. Prevention programs typically increase knowledge and appropriate attitudes about alcohol while having little effect on drinking behavior. In this article several concepts are introduced in support of a technology which has the potential to revitalize alcohol education efforts. First, Bandura's self-efficacy theory offers a direction for re-conceptualizing the design of prevention programs as well as the measurement of their effects. Second, computer-assisted instruction (CAI) programs may provide a means for capturing attention, effectively educating about alcohol, and supplementing traditional approaches. One current CAI program is described in detail. Implications for research and practice and obstacles to effective CAI use are also discussed.

In this work we present some experiments based on a measurement set up to evaluate the power consumption of VAIO SZ series while running various programs. The power consumption of the laptop is measured while running MP3 and some other programs such as Matlab and graphical games. Also, the effect of display brightness on the power consumption of the computer has been studied. The maximum power consumption is related to graphical games which are measured to be 375W. Running the MP3 with half brightness application consumed the least power of 150W. The battery life time is inversely proportional to the power consumption.

Abstract:

High-precision mass measurement equipment is required in some areas of science and technology. Physics, chemistry, pharmaceutics and high precision mechanics are common examples. In metrology, high-precision scales are used for verification and calibration of lower precision mass measurement equipment (weights and scales). Mass comparators are the most accurate mass measurement instruments available today. It is a special type of electronic scales designed to compare mass of two weights. They can be automatic or manual, with various measurement ranges and accuracy classes. This article discusses principles of operation of mass comparators and practice of high-precision mass measurement. There are special computer programs that can be used in conjunction with these instruments, which may significantly improve measurement accuracy (when mass comparator is controlled remotely) as well as simplify calculations and reporting procedures. This article describes one of these programs – ScalesNet32 – which can be used with mass comparators produced by Sartorius (Germany).

Abstract:

Previously reported data on 5 computer-based programs for measurement of joint space width focusing on discriminating ability and reproducibility are updated, showing new data. Four of 5 different programs for measuring joint space width were more discriminating than observer scoring for change in narrowing in the 12 months interval. Three of 4 programs were more discriminating than observer scoring for the 0–18 month interval. The program that failed to discriminate in the 0–12 month interval was not the same program that failed in the 0–18 month interval. The committee agreed at an interim meeting in November 2007 that an important goal for computer-based measurement programs is a 90% success rate in making measurements of joint pairs in followup studies. This means that the same joint must be measured in images of both timepoints in order to assess change over time in serial radiographs. None of the programs met this 90% threshold, but 3 programs achieved 85%–90% success rate. Intraclass correlation coefficients for assessing change in joint space width in individual joints were 0.98 or 0.99 for 4 programs. The smallest detectable change was < 0.2 mm for 4 of the 5 programs, representing 29%–36% of the change within the 99th percentile of measurements.

Abstract:

Electron diffraction is one of most widely used techniques in the characterization of specimens in the TEM. With the advent of computerization, there is a growing trend toward automation of the measurement and analysis of electron diffraction patterns (EDPs). There are a number of computer programs used for measuring, indexing, and simulating EDPs, some of which are now commercially available. Many of these programs are stand-alone programs which either perform a specific aspect of EDP analysis or require significant user interaction, particularly in the measurement phase. In some cases, the lack of suitable algorithms for measuring EDPs usually limit these programs to the extent that users still have to perform standard procedures of measuring EDPs from negatives or prints to obtain the necessary values needed to complete the execution of these programs. Here, a more convenient means for online acquisition and measurement of EDPs is presented.

Abstract:

Speculative parallelism refers to searching in parallel for a solution, such as finding a pattern in a data base, where finding the first solution terminates the whole parallel process. Different performance prediction methods are required as compared to traditional parallelism. In this paper we introduce an analytical approach to predict the execution time distribution of data-dependent parallel programs that feature N-ary and binary speculative parallel compositions. The method is based on the use of statistical moments which allows program execution time distribution to be approximated at O(1) solution complexity. Measurement results for synthetic distributions indicate an accuracy that lies in the percent range while for empirical distributions on internet search engines the prediction accuracy is acceptable, provided sufficient workload unimodality.

Abstract:

The ISO GPS and ASME Y14.5 standards have defined dimensional and geometrical tolerance as a way to express the limits of surface part variations with respect to nominal model surfaces. A quality-control process using a measuring device verifies the conformity of the parts to these tolerances. To convert the control measurement points as captured by a device such as a coordinate measurement machine (CMM) or noncontact scan, it is necessary to select the appropriate algorithm (e.g., least square size and maximum inscribed size) and to include the working hypotheses (e.g., treatment of outliers, noise filtering, and missing data). This means that the operator conducting the analysis must decide on which algorithm to use. Through a literature review of current software programs and algorithms, many inaccuracies were found. A benchmark was therefore developed to compare the algorithm performance of three computer-aided inspection (CAI) software programs. From the same point cloud and on the same specifications (requirements and tolerances), three CAI options have been tested with several dimensional and geometrical features.

Abstract:

AbstractA new method is presented, different from usual methods, for the discussion of the results of computer ECG measurement programs, based on a new graphical evaluation method. The proposed “scatter-graphs” both highlight the main program results and facilitate the comparison between various wave-recognition algorithms. They allow the distinction between the reliability of an algorithm, which is its capacity to provide a maximum of measurements with a minimum amount of errors, and its precision, i.e., the standard deviation of the differences between its point estimates and the reference.The method proves to be a powerful tool for the discussion of individual, as well as the median program results in CSE Measurement Study. It allows to highlight limitations induced in performance assessment by the variability of the reference itself, and to state that the median program is at least as close to the “Gold Standard” as the median of the referees.

Abstract:

Electron diffraction is one of the most widely used techniques in the characterization of materials in the TEM. There are a number of computer programs used for measuring, indexing, and simulating electron diffraction patterns (EDP’s), but many are stand-alone programs and require significant user interaction. For example, EDP’s obtained on the JEOL 2010 in the Texas A&M Electron Microscopy Center can be measured with the Electron Diffraction Pattern Analysis software provided with the Oxford Instruments eXL system. A separate program is used to acquire the pattern from the TV camera output, while the EDP Analysis program requires the user to select the transmitted and diffracted beams for measurement. Only two values of d-spacings are calculated by this program, which places an additional burden on the user to select other spots in order to get a more complete measurement of the pattern.In this work, we propose a more streamlined approach in acquiring, saving, and measuring EDP’s on a PC-based computer system. A schematic of the hardware/software configuration is shown in Figure 1.

Abstract:

Shape measurements in horticultural research have generally been expressed as ratios or indexes. Computer-based image analysis enables the objective quantification and statistical analysis of two-dimensional sample shape variability. In addition, the availability of public domain software facilitates the inexpensive but accurate quantification of object shape in horticultural research. We describe the procedures for measuring sample shape using the following publicly available software: ImageJ, ImageTool, and SHAPE. Using U.S. #1 sweetpotato storage root samples from plots subjected to various weed control treatments, we detected significant differences in elongation, compactness, as well as shape attributes. We also measured size and shape variability from representative fruit, leaf, and floral organ samples. The results demonstrate that, where possible, measurement of two-dimensional samples can be undertaken inexpensively and accurately using public domain software applications.

Abstract:

Henriksdal sewage treatment plant is the largest plant in Stockholm with a design flow of 370 000 m3/d. In one aeration tank of eleven a new fine-bubble aeration system has been in operation since August 1985. The tank is divided into 6 equal parts. The first part is an anoxic zone and the other five are aeration zones with tapered diffusers. Several instruments are installed in the block including separate air flow monitors in each of the five zones and D.O.-probes in the inlet and outlet of the zones. Equipment for flow measurement of settled sewage and return sludge is also installed. Every instrument is connected to a computer for data acquisition. To evaluate the efficiency of the aeration system the oxygenation transfer capacity has been calculated from the oxygen massbalance equation for each zone as a function of air flow. To solve this equation the respiration has to be known and this is done by a simple respirometer for samples of the MLSS in each zone. When the KLa-values are known as functions of the air flow the mass balance equation can be used to calculate the respiration rate in each zone. The computer has been logging data for 2 2 months, and it is possible to calculate the respiration rates in the different zones every hour during this period. It is very important to know the respiration along the tank and how it varies to get the optimal tapering of the diffusers when it is time to change the aeration system in the other 10 tanks. The calculations show a different pattern in the respiration over the year depending on the rate of nitrification. Another use of the calculation of the oxygenation transfer efficiency is to recognize if any long-term change occurs due to clogging of the diffusers.

Abstract:

Background & Objective: The paper explores a new instrument of computer vision to measure three-dimension deformation with an Internet of Things (IoT) system including Raspberry Pi, digital cameras and OpenCV programs in laboratory and field testing so as to monitor the potential deformation of a structure drainage well in a landslide. Methods: A chessboard pattern is detected in the image by the camera so that pixels of chessboard cornors can be recognized by OpenCV programs. X-direction, Y-direction and Z-distance changes can be casulated by the similar triangles relationship of camera pixels. For laboratory testing, standard deviations of the measurement were approximately 0.01 cm. Results: For field testing, the study installed four sets of Raspberry Pi in a drainage well within a landslide and employed OpenCV programs to interpret pixel changes of chessboards at four levels of the draiage well. Conclusion: Overall, the instrument can be employed for triaxial deformation monitoring of the construction in the field effectively and automatically.

Abstract:

Respiratory failure (apnea) often occurs in premature babies, this should be avoided because it causes low oxygen concentrations in the blood so that it can damage brain function and lead to death. Apnea is characterized by a decrease in oxygen saturation (SpO2). The purpose of this study was to design an apnea monitor that was detected with SpO2 parameters, alarms, and vibrating stimulation. This study uses infrared and red LEDs that emit light through the surface of the finger and is detected by a photodiode sensor, this light signal will be converted into an electrical signal and calculated by Arduino to determine the patient's SpO2 and BPM values. If the SpO2 value drops 5% within 5 seconds from the baseline, the device will indicate apnea has occurred and the vibrating motor is working. SpO2 signals and alarms are sent to the nurse station computer via Bluetooth HC-05. The instrument was calibrated with an SpO2 calibrator and the measurement results were compared with a BION pulse oximetry brand. The results of the instrument measurement on two subjects on the SpO2 parameter showed an error value of 2% and the BPM parameter obtained an error value of 4.54%. Testing the BPM parameter using a calibrator at the 30 and 60 BPM settings shows an error value of 0% and at the 120 BPM setting the error value is 0.01%. The vibrating motor to stimulate the baby's body when apnea occurs is functioning properly. The results showed that measurements using subjects tended to have high error values due to several factors. This research can be implemented on patient monitors to improve patient safety and reduce the workload of nurses or doctors

Abstract:

Software process improvement programs are partly founded on software measurement. However, despite their importance, it has been pointed out in the literature that many students are leaving the academic world without the necessary skills to conduct this kind of process. This can be understood by people’s attitudes to this process which is regarded as time-consuming and difficult to understand—factors that explain the lack of interest in it during a student’s academic life. In light of this, the application of serious games or gamification can show useful alternative ways of meeting this need, because the strategies they involve are well accepted by students and have a motivational and engaging effect on them. The objective of this work is to discover different approaches to the teaching of software measurement and software process improvement through gamification projects and serious games. This involves carrying out a systematic review of the literature, which is aimed at characterizing the state-of-the-art on the use of methods related to gamification and serious games in the abovementioned subjects. We conducted a systematic review of the literature to identify primary studies that address the use, planning, or evaluation of gamification, serious games, their features, and game mechanics in software engineering. We located 137 primary studies, published between 2000 and 2019. Although the use of serious games and gamification in software engineering is not recent, there still remains a large area to be explored, especially in software process improvement and software measurement. The study expands and advances the research on how serious games and gamification proposals can be used for teaching software measurement in the context of software process improvement programs by conducting a systematic review of the literature.

Abstract:

ABSTRACT The emergence of enormous disparate data sources, available in a multitude of alternate formats, and on very different devices, is leading to a business process revolution. This paper argues for a new approach in which these technologies are used to replace outdated blanket government intervention programs. Highly targeted interventions for social programs identified and addressed by Big Data-based methodologies would replace outdated government programs. This approach advocates for original detective methodologies, direct government action, and outcome monitoring all of which utilize Big Data-based frequent examination. The government would be in a privileged situation where it could obtain data not available to most other parties due to privacy laws. The data structures of the government would be protected by encryption and blockchain privacy-protection methodologies that would only reveal targeted outcomes to the direct-action agent. These same methodologies are applicable for business measurement (accounting) and assurance (audit).

Abstract:

The architecture of P2P file-sharing applications has been developing to meet the needs of large scale demands. The structured overlay network, also known as DHT, has been used in these applications to improve the scalability, and robustness of the system, and to make it free from single-point failure. We believe that the measurement study of the overlay network used in the real file-sharing P2P systems can provide guidance for the designing of such systems, and improve the performance of the system. In this paper, we perform the measurement in two different aspects. First, a modified client is designed to provide view to the overlay network from a single-user vision. Second, the instances of crawler programs deployed in many nodes managed to crawl the user information of the overlay network as much as possible. We also find a vulnerability in the overlay network, combined with the character of the DNS service, a more serious DDoS attack can be launched.

A novel method of detecting mechanical movement of the heart, Mechanocardiography (MCG), with no connection to the subject's body is presented. This measurement is based on radar technology and it has been proven through this research work that the acquired signal is highly correlated to the phonocardiograph signal and acceleration-based ballistocardiograph signal (BCG) recorded directly from the sternum. The heart rate and respiration rate have been extracted from the acquired signal as two possible physiological monitoring applications of the radar-based MCG device.

Abstract:

The functions of nurses in the department of gastroenterology are diverse. Nurses perform a wide range of medical appointments (injections, enemas, medication distribution, etc.), diagnostic procedures (body temperature measurement, gastric and duodenal intubation, etc.). If necessary, nurses should be able to calculate the respiratory rate and pulse rate, measure blood pressure, daily urine output, correctly collect the patient’s secretions (sputum, urine, feces) for analysis and send them to the laboratory. In urgent situations, nurses are required to be able to provide first aid (artificial respiration, chest compressions, the application of a hemostatic tourniquet) as well as first aid for gastrointestinal bleeding. This article presents evidence that the role of the nurse in gastroenterology is very important. Since some diseases in gastroenterology require urgent surgical intervention, a nurse is responsible for conducting a high-quality nursing process in the preoperative period and postoperatively for proper and timely nutrition of patients, organizes feeding of patients on strict bed rest, monitors the storage of food in refrigerators and bedside bedside tables, check the content and quality of programs.

Abstract:

Abstract Background Electronic clinical quality measures (eCQMs) seek to quantify the adherence of health care to evidence-based standards. This requires a high level of consistency to reduce the effort of data collection and ensure comparisons are valid. Yet, there is considerable variability in local data capture, in the use of data standards and in implemented documentation processes, so organizations struggle to implement quality measures and extract data reliably for comparison across patients, providers, and systems. Objective In this paper, we discuss opportunities for harmonization within and across eCQMs; specifically, at the level of the measure concept, the logical clauses or phrases, the data elements, and the codes and value sets. Methods The authors, experts in measure development, quality assurance, standards and implementation, reviewed measure structure and content to describe the state of the art for measure analysis and harmonization. Our review resulted in the identification of four measure component levels for harmonization. We provide examples for harmonization of each of the four measure components based on experience with current quality measurement programs including the Centers for Medicare and Medicaid Services eCQM programs. Results In general, there are significant issues with lack of harmonization across measure concepts, logical phrases, and data elements. This magnifies implementation problems, confuses users, and requires more elaborate data mapping and maintenance. Conclusion Comparisons using semantically equivalent data are needed to accurately measure performance and reduce workflow interruptions with the aim of reducing evidence-based care gaps. It comes as no surprise that electronic health record designed for purposes other than quality improvement and used within a fragmented care delivery system would benefit greatly from common data representation, measure harmony, and consistency. We suggest that by enabling measure authors and implementers to deliver consistent electronic quality measure content in four key areas; the industry can improve quality measurement.

Abstract:

In this paper, we present a multi-variant analysis of the determination of the accuracy of the seasonal heat demand in buildings. The research was based on the linear regression method for data obtained during short periods of measurement. The analyses were carried out using computer simulation, and the numerical models of the multifamily building and school building were used for the simulation. The simulations were performed using the TRNSYS, ESP-r, and CONTAM programs. The multi-zone models of the buildings were validated based on the measurement data. The impact of the building’s parameters (airtightness, insulation, and occupancy schedule) on the determination of the accuracy of the seasonal heat demand was analyzed. The analyses allowed guidelines to be developed for determining the seasonal energy consumption for heating and ventilation based on short periods of heat demand measurements and to determine the optimal duration of the measurement period.

Abstract:

Because of continuous movement and variation in diameter of the inferior vena cava (IVC) with respiration, the measurements on IVC are labor-intensive and with considerable inter-operator variations. Some computer-assisted techniques have been developed to track the movement of the IVC semi-automatically. However, existing methods predominantly rely on reference marker selection and require many manual inputs. In this study, we developed a cross-correlation (CC)-based method for automated IVC movement tracking and measurement, which requires minimal manual input and avoids manual selection of reference markers. Based on the CC method, two approaches, named direct and relative approaches, were used to calculate the maximum, minimum, and variation of the IVC diameter, and compared with the manual measurement. Fifty-four ultrasound cine-loops collected from nine pigs were tested. The results reveal that both the proposed approaches were well agreed with the manual measurement. The errors of the direct approach were less than 9%, while those of relative approach were as high as 26.7%. It is concluded that the proposed direct approach is superior for IVC diameter measurements, which can be comparable with manual counterpart, serving as an alternative to traditional IVC measurement.

Abstract:

Electron diffraction patterns taken in transmission electron microscopes are widely used for phase identification and orientation determination of crystallites as small as hundreds or even tens of nanometers in size. The analyses typically require rather tedious measurement of the patterns, and matching of calculated d-spacings and angles with those of known phases. Recently, the analysis of these patterns has been facilitated by powerful desktop computer programs that use digitally captured images for on-line measurement and simulation matching of" the diffraction spot and Kikuchi line patterns. This presentation will illustrate an application of computer-aided pattern simulation and matching for precise determination of crystal orientations.Two experimental TV camera arrangements were used to record diffraction patterns in a TEM. These included a cooled-CCD camera located on the electron optical axis below the microscope viewing chamber, and a simple TV-rate CCD that recorded directly from the inclined fluorescent viewing screen of the microscope.

Abstract:

Several unobtrusive sensors have been tested in studies to capture physiological reactions to stress in workplace settings. Lab studies tend to focus on assessing sensors during a specific computer task, while in situ studies tend to offer a generalized view of sensors’ efficacy for workplace stress monitoring, without discriminating different tasks. Given the variation in workplace computer activities, this study investigates the efficacy of unobtrusive sensors for stress measurement across a variety of tasks. We present a comparison of five physiological measurements obtained in a lab experiment, where participants completed six different computer tasks, while we measured their stress levels using a chest-band (ECG, respiration), a wristband (PPG and EDA), and an emerging thermal imaging method (perinasal perspiration). We found that thermal imaging can detect increased stress for most participants across all tasks, while wrist and chest sensors were less generalizable across tasks and participants. We summarize the costs and benefits of each sensor stream, and show how some computer use scenarios present usability and reliability challenges for stress monitoring with certain physiological sensors. We provide recommendations for researchers and system builders for measuring stress with physiological sensors during workplace computer use.

Abstract:

Youth and adults with autism spectrum disorder have poor skills such as communication, qualitative interaction, and emotional expression resulting in low social awareness. In this paper, we propose and explore a contactless bio-signal measurement and functional contents for improving social awareness of individuals with communication challenges. We implemented four individual methods for collecting and analyzing the bio data of the individuals without requiring their attention: (1) heart rate, (2) respiration, (3) facial expression, and (4) interaction. The four techniques are all based on image data received and analyzed from a normal web camera. The data were analyzed in a real-time, fully functional algorithm: implementing the algorithm on a mobile device will require future work. However, we have evaluated our method by developing a functional content including the four methods. Based on the analysis of the collected data from the content and qualitative responses from the field, the contactless bio-signal measurement technology combined with friendly designed user interfaces for the individuals with communication challenges could train them to improve their social awareness.

Abstract:

Values are conceptualized as the standards individuals use to determine the status of events and actions and are considered to influence individuals’ behaviours, reasoning, and perceptions. Based on a synthesis of six school-based student values enhancement programs, this paper reports on the development of the Children’s Values Questionnaire (CVQ). This Questionnaire was conceptualized as composing of seven dimensions: Self-Concept; Behaviour; Healthy Life; Social; School Climate; Emotional Intelligence; World View and 26 related sub-dimensions. A total of 848 co-educational students (52% male, 48% female) from Years (Grades) 4 to 7, ages 9 to 13+ years, across 11 Australian schools completed the 95-item CVQ Questionnaire. The Cronbach alpha coefficient of the instrument was 0.94, indicating that the questionnaire had good internal consistency. The inter-correlation between its seven dimensions clustered at Pearson r = 0.55. An exploratory factor analysis was supportive of the CVQ’s theoretical construct (Norm Fit Index of the data to the theoretical construct, 0.09). Girls rated themselves higher than boys (p < 0.001) on items related to Playing by the Rules, Responsibility, Creativity, Empathy, and Communication, and boys rated themselves higher than girls on Physical Activities items (p < 0.001). Older students (Years 6 and 7) compared to younger students (Years 4 and 5) demonstrated greater discernment and differentiation of context (p < 0.05), the growing influence of peer friendship in their value beliefs and an increase in confidence in social settings (p < 0.001). The relationship of the CVQ to Schwartz’s Universal Valued Goals is reported in the paper, along with examples of the application of the CVQ in schools.

Abstract:

The increasing development of measurement techniques for monitoring rotor plants requires improved possibilities for the interpretation of vibration response. Therefore, computer programs that have been used will have to be constantly updated. This especially concerns the modelling of a rotor for calculation purposes. This paper deals with a propagating crack that causes the slender uniform round shaft to vibrate about its main axis. Experiments using a stationary shaft are also performed. Beach marks are used to measure the crack depth and the actual shape of the cracked cross section. These results are compared with those obtained using the dc-potential method, applied to the same cracked cross-section. A finite element model for the cracked region of the rotor is then deduced from the experimental results. Three-dimensional 20-node elements are applied, so a single edge crack of the rotor can be described and varying forms of the cross section—as shown by the beach marks—can be modelled. The additional installation of nonlinear truss elements to the finite element structure permits the breathing of the cracked rotor to be calculated.

Abstract:

AbstractComputer processing of electrocardiograms (ECGs) has over the last 15 years increased rapidly. Still, there are at present no standards for computer ECG interpretation. Different techniques are used not only for measurement and interpretation, but also for transmission and storage of data. In order to fill these gaps, a large international project, sponsored by the European Commission, was launched in 1980 to develop “Common Standards for Quantitative Electrocardiography (CSE)”. The main objective of the first CSE study was to reduce the wide variation in wave measurements currently obtained by ECG computer programs. The second study was started in 1985 and aimed at the assessment and improvement of diagnostic classification of ECG interpretation programs. To this end reference libraries of well documented ECGs have been developed and comprehensive reviewing schemes devised for the visual and computer analysis of ECGs. This task was performed by a board of cardiologists in a Delphi review process, and by 9 VCG and 10 standard 12-lead programs developed by university research groups and by industry. A third action was started in June 1989 to harmonize acquisition, encoding, interchange and storing of digital ECG data. The action thus performed have become internationally recognized milestones for the standardization of quantitative electrocardiography.
