Observers adjusted a pointer to match the depicted distance of a monocular virtual object viewed in a see-through, had-mounted display. Distance information was available through motion parallax produced as the observers rocked side to side. The apparent stability of the virtual object was impaired by a time delay between the observers' head motions and the corresponding change in the object position on the display. Localizations were made for four time delays (31 ms, 64 ms, 131 ms, and 197 ms) and three depicted distances (75 cm, 95 cm, and 113 cm). The errors in localizations increased systematically with time delay and depicted distance. A model of the results shows that the judgment error and lateral projected position of the virtual object are each linearly related to time delay.

Abstract. The world is facing an unprecedented problem in safeguarding 0.4 % of potable water, which is gradually depleting day-by-day. From a literature survey it has been observed that the refractive index (RI) of water changes with a change in salinity or total dissolved solids (TDS). In this paper we have proposed an automatic system that can be used for real-time evaluation of salinity or TDS in drinking water. A photonic crystal (PhC) based ring resonator sensor has been designed and simulated using the MEEP (MIT Electromagnetic Equation Propagation) tool and the finite difference time domain (FDTD) algorithm. The modelled and designed sensor is highly sensitive to the changes in the RI of a water sample. This work includes a real-time-based natural sequence follower, which is a machine learning algorithm of the naive Bayesian type, a sequence of statistical algorithms implemented in MATLAB with reference to training data to analyse the sample water. Further interfacing has been done using the Raspberry Pi device to provide an easy display to show the result of water analysis. The main advantage of the designed sensor with an interface is to check whether the salinity or TDS in drinking water is less than 1000 ppm or not. If it is greater than or equal to 2000 ppm, the display shows “High Salinity/TDS Observed”, and if ppm are less than or equal to 1000 ppm, then the display shows “Low salinity/TDS Observed”. The proposed sensor is highly sensitive and it can detect changes in TDS level because of the influence of any dissolved substance in water.

Full textAbstract:
Eruptive activity of Semeru Volcano, East Java, Indonesia, is characterized by intermittent occurrence of strombolian and vulcanian types in intervals of 15 – 45 minutes. The explosive eruptions accompany explosion earthquakes and tilt changes of ground around the summit crater. Prior to the explosions (16 – 300 s before), gradual upward tilts of the crater side were detected with amounts of 0.3 – 20 nrad. The upward tilts turned to downward after start of explosive eruptions and tilt decreased by 0.7 – 50 nrad for 30 – 70 s. In order to detect the precursory tilt changes in real time automatically by using the tilt record, software coded by Visual Basic was developed. The software receives UDP packet data from A/D converter for the tiltmeter and shows the record on PC display. The software judge stages of volcanic activity (pre-eruption or eruption) based on the tilt change. In a test, 72% of increase in tilts prior to explosions was successfully detected.

The motivation for this study is to design a sensor device for detection of bacteria in food and water in order to guarantee food safety. Graphene is chosen as our material for sensor design, which has outstanding electrical, physical, and optical performance. In our sensor structure, graphene-based solution gate field effect transistor (FET) is the device model; fabrication and functionalization protocol are presented together in this paper. What is more, a real-time signal display system is the accompanied equipment for our designed biosensor device. In this system, the sensor bias current signalIdswould change obviously when the target bacteria are attached to the sensor surface. And the bias currentIdsincreases when theE. coliconcentration increases. In the latter part, a theoretical interpretation of the sensor signal is to explain the bias currentIdsincreasing after theE. coliK12 attachment.

An automatic flash photolysis system for the measurement of absorption decays and transient difference spectra is described. The apparatus performs a digital measurement of the light transmitted by the sample and a few on-line preprocessing operations on the measured data, such as the digital averaging of the signal and the computation of the change in absorbance. A boxcar averager, used as a gated integrator, constitutes the sampling head of the apparatus. A microprocessor-based acquisition and control unit performs a digital conversion of the value sampled by the boxcar, provides an on-line preprocessing of the data, and supervises every operation required by the measurement process. This unit is interfaced to a personal computer which allows a friendly interaction with the operator as well as the on-line display of the data. The electronic instrumentation features a time resolution of a few nanoseconds, with a boxcar averager as input head, and of a few hundreds of picoseconds, with a sampling oscilloscope as input head.

Respiratory mechanics is a difficult topic for instructors and students alike. Existing respiratory mechanics models are limited in their abilities to demonstrate any effects of rib cage movement on alveolar and intrapleural pressures. We developed a model that can be used in both large and small classroom settings. This model contains digital pressure displays and computer integration for real-time demonstration of pressure changes that correspond to the different phases of breathing. Moving the simulated diaphragm and rib cage causes a volume change that results in pressure changes visible on the digital sensors and computer display. Device testing confirmed the model's ability to accurately demonstrate pressure changes in proportion to physiological values. Classroom testing in 427 surveyed students showed improved understanding of respiratory concepts ( P < 0.05). We conclude that our respiratory mechanics model is a valuable instructional tool and provide detailed instructions for those who would like to create their own.

The primary aim of the study presented in this paper is to propose a real-time temperature data transmission approach for intelligent cooling control of mass concrete. A mathematical description of a digital temperature control model is introduced in detail. Based on pipe mounted and electrically linked temperature sensors, together with postdata handling hardware and software, a stable, real-time, highly effective temperature data transmission solution technique is developed and utilized within the intelligent mass concrete cooling control system. Once the user has issued the relevant command, the proposed programmable logic controllers (PLC) code performs all necessary steps without further interaction. The code can control the hardware, obtain, read, and perform calculations, and display the data accurately. Hardening concrete is an aggregate of complex physicochemical processes including the liberation of heat. The proposed control system prevented unwanted structural change within the massive concrete blocks caused by these exothermic processes based on an application case study analysis. In conclusion, the proposed temperature data transmission approach has proved very useful for the temperature monitoring of a high arch dam and is able to control thermal stresses in mass concrete for similar projects involving mass concrete.

Abstract Weather radar is now widely viewed by the general public in the United States via television, computers/tablets, and smartphones. Anyone can consult near-real-time maps and animations of weather radar data when weather conditions are a factor. However, the usefulness of weather radar data for each user depends on a complex interaction of factors. There have been few studies providing conceptual arguments and empirical data to better understand what the most important factors are and to comprehend patterns of public weather radar use across the United States. The first part of this research provides a basic conceptual framework for research investigating the usefulness of weather radar displays as a source of weather information and as a decision aid. The second part aims to uncover several factors that influence the perceived usefulness rating of the National Weather Service (NWS) website’s weather radar display at both national and regional levels using variables gathered from the 2014 NWS customer satisfaction survey alongside relevant geographic and climatological variables. Data analyses include spatial clustering and ordinal regression utilized within a generalized linear model methodology. Overall, respondents who are more familiar with the NWS and their products, as well as those who indicate they are more likely to take action based on information provided by the NWS, are more likely to find the NWS radar display useful. Geographically, the NWS radar display is most useful to persons residing in the southern United States. Lightning is the most important hazard associated with higher radar usefulness ratings.

This paper describes some fluid dynamic considerations for attaining realistic odor presentation using an olfactory display. Molecular diffusion is an extremely slow process and odor molecules released from their source are spread by being carried off by airflow. Therefore, we propose to use a computational fluid dynamics (CFD) simulation in conjunction with the olfactory display. The CFD solver is employed to calculate the turbulent airflow field in the given environment and the dispersal of odor molecules from their source. The simulation result is used to reproduce at the nose the realistic change in the odor concentration with time and space. However, our initial sensory test for evaluating the proposed method was not completely successful, and we also found some discrepancies between our real-life olfactory sensation and the experience of the CFD-based olfactory display. Here we report some insights to overcome these problems. In the initial sensory test, a nontrivial portion of the subjects did not properly recognize the spatial variation in the odor intensity. The result of our recent sensory test is presented in this paper to show that better contrast in the perceived odor intensity can be provided when the concentration range of the released odor is adjusted for the variation in the olfactory sensitivity of individual subjects. We noted that olfactory adaptation occurred more quickly in the initial sensory test of the CFD-based olfactory display than in real environments. In this paper, we show that olfactory adaptation can be alleviated by modulating the odor concentration randomly to mimic the random fluctuations of the turbulent flow fields in real environments. We also noted in our initial sensory test that there were sometimes discrepancies between our olfactory sensation in real environments and the simulated odor distribution. We show in this paper that the discrepancy can be attributed to the convection caused by the human body temperature that brings an odor vapor that is drifting around our feet up to our noses.

Brain is one of the most vital parts for humans, with the number of brain function that is needed for the body, the brain becomes a very important part of the human body. If there is damage to the brain will certainly cause the performance of the human body will not run properly. Because of that, it’s very important to maintain brain health. There is a way to maintain brain health, for example is by doing brain exercise. Examples of brain exercise is to do simple math calculations or doing brain games like sudoku. Because of that, created a tool that can help the brain to maintain brain exercise. The tool is called math clock. Making math clock tool consists of hardware and software. The hardware consists of RTC as real time data input, ATmega328 as microcontroller and dot matrix 32x16 as a tool to display the output that has been processed by the microcontroller. The software is built using C with Arduino IDE. Math clock will process the data from RTC then processed it, in microcontroller so when output displayed on dot matrix, output will be simple mathematical operation with real time clock data on it. Test results show that, math clock is capable of displaying a simple mathematical calculation operations such as addition, subtraction, multiplication and division. The mathematical operation that display on math clock, appears to be random, so it’s not triggered by same mathematical operation. In math clock the display will change every 20 second, so in 1 minute there are 3 different kinds of mathematical operations. The results of questionnaires of 10 different students, showed 9 out of 10 students said math clock is a tool that easy to use as a clock. Math clock will be alternative for doing brain exercise every day.

A fundamental objective in membrane biology is to understand and predict how a protein sequence folds and orients in a lipid bilayer. Establishing the principles governing membrane protein folding is central to understanding the molecular basis for membrane proteins that display multiple topologies, the intrinsic dynamic organization of membrane proteins, and membrane protein conformational disorders resulting in disease. We previously established that lactose permease of Escherichia coli displays a mixture of topological conformations and undergoes postassembly bidirectional changes in orientation within the lipid bilayer triggered by a change in membrane phosphatidylethanolamine content, both in vivo and in vitro. However, the physiological implications and mechanism of dynamic structural reorganization of membrane proteins due to changes in lipid environment are limited by the lack of approaches addressing the kinetic parameters of transmembrane protein flipping. In this study, real-time fluorescence spectroscopy was used to determine the rates of protein flipping in the lipid bilayer in both directions and transbilayer flipping of lipids triggered by a change in proteoliposome lipid composition. Our results provide, for the first time to our knowledge, a dynamic picture of these events and demonstrate that membrane protein topological rearrangements in response to lipid modulations occur rapidly following a threshold change in proteoliposome lipid composition. Protein flipping was not accompanied by extensive lipid-dependent unfolding of transmembrane domains. Establishment of lipid bilayer asymmetry was not required but may accelerate the rate of protein flipping. Membrane protein flipping was found to accelerate the rate of transbilayer flipping of lipids.

Medical infusion device provides drugs or fluids directly through a blood vessel. However, the occurrence of occlusion in the infusion device causes the incoming drug fluid does not to flow constantly, and pressure is formed on the infusion tube. When an infusion device has been used for a long time, there will be a change in the precision of the flow and pressure values. Furthermore, a calibration process must be carried out at least once a year. This research aims to design an infusion device analyzer which able to show parameters in a graphic equipped with occlusion parameters and Bluetooth communication in real-time to the computer unit. This study uses a solenoid valve for pressure simulation. The allowable occlusion limit is <20 Psi. The SKU 237545 sensor detects the water pressure that is blocked by the solenoid valve. Then the data will be displayed on the Parallax data acquisitions using Bluetooth communication. The Parallax data acquisitions will display real-time occlusion data, data averages, instant values, and graphs. The results of the IDA design, when tested using the Syringe Pump TOP 5300, obtained an average of 0.68 Psi. Meanwhile, when the IDA design was tested using the Infusion Pump 3300, it brought 0.73 Psi. Furthermore, it showed that the occlusion parameter was compared with the Fluke IDA 4, a mean error was 0.7 Psi. Therefore, it can be concluded that this IDA design can be used for calibration to see the feasibility of an infusion pump or syringe pump.

A major disadvantage of nearly every marine electronic navigation device introduced to date is the necessity for the navigator to turn his or her attention away from the view outside the bridge windows, even momentarily. Indeed, the uncomfortable feeling experienced by seasoned mariners that this ‘head down’ posture creates has led many to be initially reluctant to adopt some marine electronic devices (radar, ARPA, ECDIS, to name a few) that have proven their worth over time as useful, even vital navigational aids. Unfortunately, the use of such equipment has always required the marine navigator to leave behind the real world perspective view and enter an unnatural, two-dimensional plan view of the area surrounding the vessel. Mariners have accepted this type of view by necessity rather than by choice. That may be about to change. Advances in technology and a proven track record of performance benefits from Head-Up Display (or HUD) information in the aviation field have made it possible to consider if such a device would be useful in a maritime context. Accordingly, the authors of this paper conducted a preliminary evaluation to examine empirically what the effects of providing this same type of head-up information would be on marine navigation performance. A series of tests were conducted in the California Maritime Academy's advanced simulation facilities utilizing a full-mission simulator, a laptop-based HUD prototype, a projector, and student participants from an experimental undergraduate course entitled e-Navigation. The goals were to: 1) define the operational requirements and concept of operations for a maritime HUD system; 2) identify essential information, risks, and concerns; and 3) examine performance variations by conditions (environmental, vessel, crew) and tasks. The results indicate great potential for a maritime HUD system, especially for improving situational awareness in low visibility conditions, confined waters, and for vessels where information changes rapidly (i.e., high speed vessels). The results also suggest that there are some standard information requirements across situations that could be augmented with task and vessel specific information.

Full textAbstract:
We describe the gamification of a soft physics simulator. We developed a game, called Jelly Dude, that allows the player to change and modify the game engine by tinkering with various physics parameters, creating custom game levels and installing scripts. The game engine is capable of simulating soft-body physics and can display the simulation results visually in real-time. In order to ensure high quality graphics in real time, we have implemented intelligent computational offloading to the cloud using Jordan Neural Network (JNN) with a fuzzy logic scheme for short time prediction of network traffic between a client and a cloud server. The experimental results show that computation offloading allowed us to increase the speed of graphics rendering in terms of frames per second, and to improve the precision of soft body modeling in terms of the number of particles used to represent a soft body.

This paper introduces the application method of a measuring system for visual judgment ability of drivers in real three-dimension space (3D) based on the visual attention theory. The measuring system can simulate the traffic environment and driving conditions, and is made up of five parts, signal display system, data recording system, traffic environment simulation system, experimental seat and computer control system. It can control the peripheral environment illuminance and the appearance of stimulus at the target locations, and change the colour of stimulus. The paper demonstrated that the measuring system can be used to examine the reaction time and judgment response of drivers in real three-dimension space during driving, and show that the response ability training for visual attention of drivers can improve the vision judgment ability.

Full textAbstract:
For video art, the coupling of digital technology and postmodernist thinking has brought not only technical progress and formal transformation but also a new mode of thinking and way of living around visual experience and even a change in the whole world view. The digitalization of the image not only lies in the change of the surface form, but also it has evolved into a supermedium, connecting the real world and the virtual world, becoming a new way and means for us to grasp the world, which can be considered a huge transformation. However, while digitalization has brought great development to video art, it has also confused many issues that need to be further explored, especially the inevitable transformation in creation. This paper takes digital video art as the main object of study and explores the crisis of representation and the problem of transformation that has arisen in it, with reference to “technology,” “form,” “concept,” and even “social and cultural life.” We also analyze, summarize, and conclude the transformation of video art and its creation rules in the digital context and propose corresponding creation strategies, taking “technology,” “form,” “concept,” and even “social and cultural life“ as the starting point. For the detection of a small area, a star structure can be used to achieve a flexible arrangement of each sensor while satisfying the real-time performance. For the collection of information in a large monitoring area, if a star structure is used, the nodes are overloaded with low reliability and low utilization of communication lines. The wireless data acquisition system uses the relatively scalable UCB telosb hardware platform, while the hardware platform uses an operating system with good portability, which can give full play to the hardware performance of the platform and effectively reduce the power consumption of the system. Based on the current art trend, this paper discusses the transformation of video art in the digital background from the perspective of “technology” and “concept” and proposes corresponding creation strategies to provide theoretical to practical support for digital video art creation practice and bring some inspiration to creators. It will also bring some inspiration to the creators. Cluster analysis is used to effectively improve the introduced algorithm, and the simulation results show that the improved algorithm can reasonably plan each sensor node in the region while reducing the number of sensors, so that the effectiveness of each sensor node can be well utilized.

This speculative proposes an approach towards enhancing the real time experience while using the Maps. It is an all-in-one for most of the information about a particular area, cities, states, countries, which include salient features like, ‘Crime Report’, ‘Population Density’, ‘Covid Cases’, ‘Average Temperature Change’, ‘Climate Change’, ’Sex Ratio’. The interactive maps assist us in conveying complicated information in a more straightforward manner. They help the user to have more engaging usage of application than regular static map. Interactive maps involve representing the maps which allows zoom in and zoom out, identifying the specific features by just hovering over the map without typing queries. The map also maintains highdefinition picture quality while zooming in. This is used to produce a summary and various ways to use or visualize data source on the map. The GSI (Global Information System) is used in interactive mapping to display pinpoint data on a map. The many tiers of geographical information are layered on top of each other using a layering approach. Unlike static maps, interactive maps offer a lot of characteristics that help to display a vast quantity of complex data more effectively.

We propose the concept of FTV and veri¯ed its feasibility using the world's ¯rst real-time system including the complete chain of operation from image capture to display. The international standardization of FTV technologies is now underway. FTV is a ray based system rather than a pixel-based system.

As various sensors and PLC are set in the mine, the system is able to achieve real-time monitoring and display towards the working state and working environment parameters for the fans and motors in the mine. With intelligent analytical technologies, the system will optimally regulate the start-up and shut-down or running frequency of all fans according to the change of personnel, equipment and working environment parameters, and play a role in dynamic display, early warning and remote control for the mine ventilation system. Practice has proved that the application of the system in the production of Jinshandian Iron Mine has successfully protected the staff and equipment, realized the remote central monitoring and controlling for the production, improved the automatic management for mining enterprises, and reduced the cost for ventilation.

Full textAbstract:
RET oncogene mutations are found in familial medullary thyroid carcinomas (MTC) and in one-third of sporadic cases. Oncogenic mechanisms involved in non-RET mutated sporadic MTC remain unclear. To study alterations associated with the development of both inherited and sporadic MTC, pangenomic DNA microarrays were used to analyze the transcriptome of 13 MTCs (four familial and nine sporadic). By using an ANOVA test, a list of 173 gene sequences with at least a twofold change expression was obtained. A subset of differentially expressed genes was controlled by real-time quantitative PCR and immunohistochemistry on a larger collection of MTCs. The expression pattern of those genes allowed us to distinguish two groups of sporadic tumors. The first group displays an expression profile similar to that expressed by inherited RET634 tumors. The second presents an expression profile close to that displayed by inherited RET918 tumors and includes tumors from patients with distant metastases. It is characterized by the overexpression of genes involved in proliferation and invasion (PTN, ESM1, and CEACAM6) or matrix remodeling (COL1A1, COL1A2, and FAP). Interestingly, RET918 tumors showed overexpression of the PTN gene, encoding pleiotrophin, a protein associated with metastasis. Using a MTC cell line, silencing of RET induced the inhibition of PTN gene expression. Overall, our results suggest that familial MTC and sporadic MTC could activate similar oncogenic pathways.

Full textAbstract:
OBJECTIVES/SPECIFIC AIMS: The purpose of this study was to provide individuals who have experience with cognitive behavioral therapy (CBT) with a demonstration of how using their therapeutic strategies affects their brain activity. Two challenges that face CBT and other cognitive therapies are (1) sustaining the gradual, incremental behavioral changes characteristic of the treatment and (2) measuring associated biological changes. These challenges may impede treatment efficacy and may negatively affect treatment outcomes, including patient discontinuation of CBT. Ideas for addressing these issues include providing patients with (1) a more immediate indicator of therapy effectiveness as well as (2) a biological index of behavioral change. In this study, we aimed to provide participants with an index of biological change based on therapeutic experiences via use of real-time functional magnetic resonance imaging (rtfMRI) neurofeedback. METHODS/STUDY POPULATION: We recruited participants who had already completed cognitive therapy as part of a clinical trial for depression at the University of North Carolina at Greensboro (n=13). In the present experiment, participants were asked to provide a list of negative autobiographical memories or worries as well as cognitive strategies they use to cope with negative moods. The task consisted of COUNT, MEMORY, and STRATEGY trials (30 s each). During baseline COUNT trials, participants counted backwards (e.g., 300–4). During MEMORY trials, they viewed phrases previously developed describing their negative autobiographical memories/worries. During STRATEGY trials participants viewed a strategy they use to help them process the memory/worry. First, a localizer run was completed to determine a unique region of interest for each participant. We identified peak activation within the cingulate cortex to the contrast of MEMORY (STRATEGY+COUNT). Although the task was the same, no neurofeedback was displayed during the localizer run. During the feedback runs, participants were shown neurofeedback from the cingulate cortex following both the MEMORY and STRATEGY trials. This activation was represented on a signal bar display and represented the average cingulate activation during the trial. Unlike many rtfMRI studies, the purpose here was not for participants to interact with the neurofeedback directly. Rather, a feedback summary was shown to participants after each MEMORY and STRATEGY trial as an index of how brain activity changed in response to negative memories/worries and therapeutic strategies. Our goal was not for participants to learn to self-regulate the cingulate cortex, but rather to provide participants with a metacognitive demonstration of strategy efficacy. Participants were given detailed instructions regarding the task design, the role of the cingulate cortex in depression, as well as the hypothesized direction of activation during the MEMORY and STRATEGY phases to help them interpret the neurofeedback. RESULTS/ANTICIPATED RESULTS: Results revealed that “stronger neurofeedback” (defined as the difference between STRATEGY vs. MEMORY trials) correlated with self-reported strategy efficacy ratings immediately following the scan session (p<0.05). More importantly, stronger neurofeedback predicted both self-reported strategy efficacy and frequency of use 1 month following the MRI session (p<0.05). Importantly, this relationship was specific to only those strategies used inside the scanner; and no such relationship was observed at baseline. Neuroimaging results revealed that during the MEMORY phase, activation within inferior frontal gyrus and supramarginal gyrus correlated with baseline BDI score (whole brain, cluster corrected with FSL Flame 1 to p<0.05). During the STRATEGY phase, the periaqueductal gray nucleus, insula, and temporal pole predicted self-reported frequency of strategy use 1 month post-scan session (whole brain, cluster corrected with FSL Flame 1 to p<0.05). DISCUSSION/SIGNIFICANCE OF IMPACT: We believe this study holds promise to provide a powerful demonstration for individuals that strategies used to cope with negative moods can produce significant changes in their brain.

Abstract This article deals with the cultural-historical change of public self-presentation and construction of identity at the end of the 19th century with the examples of William F. Cody (“Buffalo Bill”) and Karl May. The impact of the various public, both real and virtual, stages, the change of selfrepresentation as response to public reaction, and the interaction of public and private self-perception will be examined in particular with regard to the question how authenticity and illusion are negotiated individually and socially (within the media and publicly). The importance of physical presentation (as a sign of authenticity) and the increasing necessity to claim and proof (and thus to simulate) “reality” are particular objects of study. Both sample cases, within the specific cultural-historical context of their time, demonstrate change and diversification of public self-presentations which already display in their increasing virtuosity and plurality important aspects of modern mass mediality.

Full textAbstract:
This paper focuses on the development of a real-time wearable assist system for upper extremity throwing action based on the accelerometers of inertial measurement unit (IMU) sensors. This real-time assist system can be utilized to the learning, rectification, and rehabilitation for the upper extremity throwing action of players in the field of baseball, where incorrect throwing phases are recognized by a delicate action analysis. The throwing action includes not only the posture characteristics of each phase, but also the transition of continuous posture movements, which is more complex when compared to general action recognition with no continuous phase change. In this work, we have considered six serial phases including wind-up, stride, arm cocking, arm acceleration, arm deceleration, and follow-through in the throwing action recognition process. The continuous movement of each phase of the throwing action is represented by a one-dimensional data sequence after the three-axial acceleration signals are processed by efficient noise filtering based on Kalman filter followed by conversion processes such as leveling and labeling techniques. The longest common subsequence (LCS) method is then used to determine the six serial phases of the throwing action by verifying the sequence data with a sample sequence. We have incorporated various intelligent action recognition functions including automatic recognition for getting ready status, starting movement, handle interrupt situation, and detailed posture transition in the proposed assist system. Moreover, a liquid crystal display (LCD) panel and mobile interface are incorporated into the developed assist system to make it more user-friendly. The real-time system provides precise comments to assist players to attain improved throwing action by analyzing their posture during throwing action. Various experiments were conducted to analyze the efficiency and practicality of the developed assist system as part of this work. We have obtained an average percentage accuracy of 95.14%, 91.42%, and 95.14%, respectively, for all the three users considered in this study. We were able to successfully recognize the throwing action with good precision and the high percentage accuracy exhibited by the proposed assist system indicates its excellent performance.

Full textAbstract:
Water quality from the Murray River, Australia, can vary considerably and is expected to become more challenging to treat due to recent drought followed by widespread flooding and future climate change impacts. Better tools are required to help plant operators maintain water quality. Morgan water treatment plant (WTP) operates overnight to take advantage of off-peak electricity, however the stop/start practices add an additional complication to accurate coagulant dosing. Online monitoring and feed forward prediction is ideal in these situations as it can provide information while there is still a chance to make adjustments, unlike the feedback (post-dosing) control achieved with many other methods. Using a multiport sampling arrangement, water quality was monitored at Morgan WTP for a 6 month period. Data were validated against other online parameters and laboratory measured samples. In a comparison of predicted versus actual plant dose, results showed that treatment was optimised when the plant dose was changed in response to product water quality deterioration and eventually matched the prediction, even though this was not known to the operators at the time. The software prediction demonstrated faster reaction to inlet water quality changes and can produce more stable treated water quality. The predicted dose was added to the operator's Supervisory Control and Data Acquisition (SCADA) system for several months as a real-time display to provide an additional tool to aid decision making and instill confidence in the resulting water quality.

Colonial Englishes have been observed to contain both archaic and innovative linguistic features, and are thus seen to display evidence of both language preservation and change. This paper examines the use of certain phonological features of New Zealand English (NZE) and discusses their status as relics or innovations. Examination is made of the diphthong which occurs in the mouth lexical set and the front short vowels trap, dress and kit. Trends in usage are studied using real time analysis of speakers recorded in the 1940s and their present day descendants recorded in 1993/94. In this way, the development of NZE is charted by means of the analysis of different generations of the same New Zealand families.

Full textAbstract:
With auditory augmentation, the authors describe building blocks supporting the design of data representation tools, which unobtrusively alter the auditory characteristics of structure-borne sounds. The system enriches the structure-borne sound of objects with a sonification of (near) real time data streams. The object’s auditory gestalt is shaped by data-driven parameters, creating a subtle display for ambient data streams. Auditory augmentation can be easily overlaid to existing sounds, and does not change prominent auditory features of the augmented objects like the sound’s timing or its level. In a peripheral monitoring situation, the data stay out of the users’ attention, which thereby remains free to focus on a primary task. However, any characteristic sound change will catch the users’ attention. This article describes the principles of auditory augmentation, gives an introduction to the Reim Software Toolbox, and presents the first observations made in a preliminary long-term user study.

Objective: To identify altered gene expression in the dorsolateral prefrontal cortex obtained after death from subjects with schizophrenia. Method: Restriction fragment differential display (RFDD) was used to measure levels of mRNA in Brodmann area (BA) 46 from schizophrenia and control subjects. Findings on specific mRNA identified with RFDD were further investigated using real-time polymerase chain reaction (real-time PCR), PCR and western blotting. Results: Levels of mRNA for 63 of approximately 12 500 genes differed in BA 46 in schizophrenia. Subsequent real-time PCR has shown that mRNA for muscleblind protein 1 ( MBNL1) and protocadherin 17 ( PCDH17) are increased in BA 46 from subjects with schizophrenia of short, but not long, duration. Altered levels of mRNA for neither gene were present in BA 9 from subjects with schizophrenia or in either cortical area from subjects with bipolar 1 disorder. By contrast, both RFDD and real-time PCR failed to show altered expression of the schizophrenia candidate gene disrupted in schizophrenia 1 ( DISC1) BA46 from any diagnostic cohort. Conclusion: The present study has identified genes that are differentially expressed in BA 46 in schizophrenia. Initial studies have shown that there is a need for a careful validation of genes shown to be affected in schizophrenia using high-throughput technologies. In addition the present study has shown that gene expression may vary considerably depending on the duration of schizophrenia. This raises the hypothesis that changing gene expression may be underlying the change in symptom profile that occurs with disease progression in some subjects with schizophrenia.

Full textAbstract:
The ocean carbon cycle has a significant influence on global climate, and is commonly evaluated using time-series satellite-derived CO<sub>2</sub> flux data. Location-aware and globe-based visualization is an important technique for analyzing and presenting the evolution of climate change. To achieve realistic simulation of the spatiotemporal dynamics of ocean carbon, a cloud-driven digital earth platform is developed to support the interactive analysis and display of multi-geospatial data, and an original visualization method based on our digital earth is proposed to demonstrate the spatiotemporal variations of carbon sinks and sources using time-series satellite data. Specifically, a volume rendering technique using half-angle slicing and particle system is implemented to dynamically display the released or absorbed CO<sub>2</sub> gas. To enable location-aware visualization within the virtual globe, we present a 3D particlemapping algorithm to render particle-slicing textures onto geospace. In addition, a GPU-based interpolation framework using CUDA during real-time rendering is designed to obtain smooth effects in both spatial and temporal dimensions. To demonstrate the capabilities of the proposed method, a series of satellite data is applied to simulate the air-sea carbon cycle in the China Sea. The results show that the suggested strategies provide realistic simulation effects and acceptable interactive performance on the digital earth.

AbstractA 64-element phased-array echocardiographic transducer mounted on a sliding carriage was used transthoracically in 11 patients with subaortic obstruction caused by various different morphological substrates. The transducer is moved in a plane from the outflow tract to the apex of the heart in steps of 0.5 to 1.3 mm and records a tomographic slice of the heart at each step. Parallel images are recorded at a frame rate of 25–30 images per second and triggered to heart rate and respiration. A complete cardiac cycle is recorded at each level. The images are digitized and stored in the image-processing computer, which reconstructs the anatomic structures of the heart in a three-dimensional format by means of different gray-scales. Good quality echocardiographic pictures were obtained in 10 of the 11 patients and three-dimensional reconstructions were possible in those 10 patients. The technique is able to display the heart in real-time in any desired plane, and in up to five planes simultaneously, without the need to change the position of the transducer on the chest. Thus the best views with which to display the substrate of subaortic stenosis could be selected. The left ventricular outflow tract could also be displayed in a view similiar to the one obtained by the surgeon during operative procedures for resection of the subaortic stenosis through an incision in the aortic root. Image acquisition took three to five minutes, and three-dimensional reconstruction of various cardiac structures took 20–90 minutes. Display of the subaortic area in three-dimensional format may enhance our understanding of cardiac anatomy and identify the different morphological lesions in the left ventricular outflow tract which cause subaortic obstruction.

As a kind of wide band-gap material focused on in recent years, SnO2 thin Film with μm level has been widely applied in many fields such as solar cells, electric heating devices, transparent electrodes, and gas sensors, ect. This paper develops a real-time system to measure thermal expansion coefficients of SnO2 thin film, which can obtain directly surface morphology information of the samples. Micro-imaging and digital image correlation method is adopted to investigate the correlation by comparing the object surface image before deformation with that after deformation. Because of the lower demand for measurement environment and no damage to object, it’s easy to acquire on-line images, calculate synchronously and display real-time results. In the paper, thermal expansion coefficients of SnO2 thin film are determined in situ with change of the temperature. Both of ceramic and SnO2 thin film have shown anisotropy thermal expansion, thermal and residual stress appears between the ceramic substrate and SnO2 thin film as a result of thermal expansion coefficients mismatch. According to experimental results, the maximum stress values can be calculated between film and substrate and inside the substrate.

Pollution is adding contaminants into the nature that causes an adverse change in the environment. Air pollution is one of the highest mortality risk factors globally. The sources of air pollution in the industries are power plants, chamber process, cleaning, burning of materials, etc. A variety of pollutants emitted into the air such as sulfur dioxide, carbon monoxide, carbon dioxide, ammonia and volatile organic compounds. Particulate Matter (PM) is an air pollutant that is the mixture of solid dust or pollen and liquid droplets with air. Air pollution in industrial workplaces is a major concern and monitoring and management of it to be addressed to protect the industrial workers health from the air pollution effects. The people are suffering from several respiratory and heart issues along with cancer due to increasing air pollution. This device is composed of ESP32 MCU, MQ135 gas sensor, SDS011 optical dust particle sensor, and BME280 humidity and temperature sensor for monitoring the air quality. The gas sensor MQ135 senses the harmful gases present in the environment. SDS011 optical dust sensor senses the PM levels (PM10 and PM2.5) in the atmosphere. The sensor values are evaluated for the Air Quality Index (AQI) and display it on the ThingSpeak IoT platform. Vrituino app has used for a virtual screen with widgets on the mobile phone to monitor the system using the web. In order to improve the real-time performance of the system, an IoT and a cloud computing technology are being used. The ESP32 turns on the fan units to maintain the pollutants within the safe limit when the presence of harmful gases and PM levels exceeds a certain threshold level. This system is essential for industrial work places to adopt measures and control air pollution which increase industrial workers safety.

International Journal of Distributed Sensor Networks 15, no. 12 (December 2019): 155014771989256. http://dx.doi.org/10.1177/1550147719892562.
Full textAbstract:
Recently, as demand for high-quality video and realistic media has increased, High Efficiency Video Coding has been standardized. However, High Efficiency Video Coding requires heavy cost in terms of computational complexity to achieve high coding efficiency, which causes problems in fast coding processing and real-time processing. In particular, High Efficiency Video Coding inter-coding has heavy computational complexity, and the High Efficiency Video Coding inter prediction uses reference pictures to improve coding efficiency. The reference pictures are typically signaled in two independent lists according to the display order, to be used for forward and backward prediction. If an event occurs in the input video, such as a scene change, the inter prediction performs unnecessary computations. Therefore, the reference picture list should be reconfigured to improve the inter prediction performance and reduce computational complexity. To address this problem, this article proposes a method to reduce computational complexity for fast High Efficiency Video Coding encoding using information such as scene changes obtained from the input video through preprocessing. Furthermore, reference picture lists are reconstructed by sorting the reference pictures by similarity to the current coded picture using Angular Second Moment, Contrast, Entropy, and Correlation, which are image texture parameters from the input video. Simulations are used to show that both the encoding time and coding efficiency could be improved simultaneously by applying the proposed algorithms.

In the past decade, the rush to technology has created several flaws in terms of managing computers, applications, and middleware and information systems. Therefore, organizations struggle to understand how these elements behave. Even today, as Enterprise Architectures grow in significance and are acknowledged as advantageous artifacts to help manage change, their benefit to the organization has yet to be fully explored. In this paper, the authors focus on the challenge of real-time information systems evaluation, using the enterprise architecture as a boundary object and a base for communication. The solution proposed is comprised of five major steps: establishing a strong conceptual base on the evaluation of information systems, defining a high level language for this activity, extending an architecture creation pipeline, creating a framework that automates it, and the framework’s implementation. The conceptual framework proposed avoids imprecise definitions of quality and quality attributes, was materialized in a model-eval-display loop framework, and was implemented using Model Driven Software Development practices and tools. Finally, a prototype is applied to a real-world scenario to verify the conceptual solution in practice.

TechnoHeart is a digital way of monitoring heart rate using a Heart Rate Monitor device and an android phone. Moreover, this is made more special through its work-out training which is designed to help users set and achieve their target heart rate and monitor at what training intensity they are during a strenuous exercise. The training is made more interactive as the application has its real-time audio coaching. The need for this application comes from three sources; First, some athletes, non-athletes and even doctors are still using the traditional way of getting the heart rate; Second, training intensity is not monitored and target heart rate is not achieved; Third, most mobile developments do not tailor the need of users who undergo work-out training. With the following needs, objectives were set; First, to connect an HRM (Heart Rate Monitoring) device to an android mobile device and display individual’s heart rate in digital form through mobile; Second, to create a work-out training program using the Karvonen Formula; Third, to enable users to know one’s target heart rate by using a Karvonen calculator; Fourth, to notify users in real-time with every sudden change and the needed action in order to keep an effective training exercise. The project is to explore this and other similar concepts to develop a design that optimally satisfies all of these objectives. The project addresses all of these objectives while meeting the constraints given. The project was deployed in three different sets of users: The University of Mindanao Athletes, The elderly users aging from 50-80 years old and the other users aging from 12-49 years old. The researchers recommend the use of TechnoHeart for athletes and non-athletes who are aiming for effective cardiovascular training. And for the next researchers, they can focus on the compatibility of the said application to other mobile platforms like iOS, Blackberry, Windows and etc. And also, they may upload the application on the internet such as in social networking sites or any features that would make this project more usable.

Vision-induced gustatory manipulation interfaces can help people with dietary restrictions feel as if they are eating what they want by modulating the appearance of the alternative foods they are eating in reality. However, it is still unclear whether vision-induced gustatory change persists beyond a single bite, how the sensation changes over time, and how it varies among individuals from different cultural backgrounds. The present paper reports on a user study conducted to answer these questions using a generative adversarial network (GAN)-based real-time image-to-image translation system. In the user study, 16 participants were presented somen noodles or steamed rice through a video see-through head mounted display (HMD) both in two conditions; without or with visual modulation (somen noodles and steamed rice were translated into ramen noodles and curry and rice, respectively), and brought food to the mouth and tasted it five times with an interval of two minutes. The results of the experiments revealed that vision-induced gustatory manipulation is persistent in many participants. Their persistent gustatory changes are divided into three groups: those in which the intensity of the gustatory change gradually increased, those in which it gradually decreased, and those in which it did not fluctuate, each with about the same number of participants. Although the generalizability is limited due to the small population, it was also found that non-Japanese and male participants tended to perceive stronger gustatory manipulation compared to Japanese and female participants. We believe that our study deepens our understanding and insight into vision-induced gustatory manipulation and encourages further investigation.
