ABSTRACT

Featured ApplicationRadiation thermometry of real objects under real conditions.Despite great technical capabilities, the theory of non-contact temperature measurement is usually not fully applicable to the use of measuring instruments in practice. While black body calibrations and black body radiation thermometry (BBRT) are in practice well established and easy to accomplish, this calibration protocol is never fully applicable to measurements of real objects under real conditions. Currently, the best approximation to real-world radiation thermometry is grey body radiation thermometry (GBRT), which is supported by most measuring instruments to date. Nevertheless, the metrological requirements necessitate traceability;therefore, real body radiation thermometry (RBRT) method is required for temperature measurements of real bodies. This article documents the current state of temperature calculation algorithms for radiation thermometers and the creation of a traceable model for radiation thermometry of real bodies that uses an inverse model of the system of measurement to compensate for the loss of data caused by spectral integration, which occurs when thermal radiation is absorbed on the active surface of the sensor. To solve this problem, a hybrid model is proposed in which the spectral input parameters are converted to scalar inputs of a traditional scalar inverse model for GBRT. The method for calculating effective parameters, which corresponds to a system of measurement, is proposed and verified with the theoretical simulation model of non-contact thermometry. The sum of effective instrumental parameters is presented for different temperatures to show that the rule of GBRT, according to which the sum of instrumental emissivity and instrumental reflectivity is equal to 1, does not apply to RBRT. Using the derived models of radiation thermometry, the uncertainty of radiation thermometry due to the uncertainty of spectral emissivity was analysed by simulated worst-case measurements through temperature ranges of various radiation thermometers. This newly developed model for RBRT with known uncertainty of measurement enables traceable measurements using radiation thermometry under any conditions.

ABSTRACT

Presentations spanned a range of applications: the public health impacts of poor air quality and environmental justice;greenhouse gas measuring, monitoring, reporting, and verification (GHG MMRV);stratospheric ozone monitoring;and various applications of satellite observations to improve models, including data assimilation in global Earth system models. The combination of methane (CH4), carbon dioxide (CO2), carbon monoxide (CO), and NO2 retrievals can improve confidence in emissions inventories and model performance, and together these data products would be of use in future air quality management tools. The ability to retrieve additional trace gases (e.g., ethane, isoprene, and ammonia) in the thermal IR along with those measured in the UV–Vis–NIR region would be extremely useful for air quality applications, including source apportionment analysis (e.g., for oil/natural gas extraction, biogenic, and agricultural sources). Ground-level ozone is one of six criteria pollutants for which the EPA sets National Ambient Air Quality Standards (NAAQS) to protect against human health and welfare effects.

ABSTRACT

In this pandemic period, social distancing is essential to avoid the spreading of the Covid-19 disease. Also, vaccination is one of the critical aspects. According to that, there is aninnovate idea of a project which fulfills all the above aspects such as Social Distancing, Physical touch, Vaccination details, and also Temperature detection. During this Covid-19, people were suffered a lot, so on a social and noble cause, it's our responsibility to think and develop products that will help us to prevent this disease as much as possible, which is going to be our primary goal and also by using advanced technologies like face recognition and temperature measuring device, so there is need to make our model much more efficient and trustworthy. In today's era, security has played a pivotal role in many of our places, like offices, institutions, libraries, laboratories, etc., to keep our data confidential so that no other unauthorized person could access them. This project presents a face-recognition-based door opening system that provides security and can be used for many banks, institutes, organizations, etc. For verifying the authentification, there are various methods like passwords and RFID, but this method is the most efficient and reliable. Temperature is sensed by the sensor and is validated for security purposes. If the temperature matches, then a camera is open, and after face-Recognition, the door will be get opened automatically.

ABSTRACT

PurposeThis article explores how internal communication impacts happiness at work and intrapreneurship through the dimensions of communication climate and communication in meetings.Design/methodology/approachLiterature analysis and quantitative empirical data collection are used to achieve this study's purpose. The study employed a non-experimental, cross-sectional, explanatory design. A questionnaire of closed-ended questions was used, adapted from validated scales for measuring constructs, and apply to 156 employees of industrial, service and commercial companies in the Northeast of Mexico. The analysis techniques used included exploratory factor analysis and structural equation modelling.FindingsIn the descriptive analysis of the data, the authors find that 57.7% of the sample is satisfied with the communication climate, 28.85% moderately satisfied, and 13.47% dissatisfied. Regarding the levels of happiness at work, high (71.15%), medium (21.15%) and low (7.7%) levels were found. In intrapreneurship, high (67.31%), medium (26.92%) and low (5.77%) levels were found. The exploratory factorial analysis showed that the instrument was adequate for measuring the variables. Good correlations were also found between the items that make up each variable. Finally, the relationship between internal communication, measured by the dimensions of communicative climate and communication in meetings, and happiness at work was verified using the structural equation technique. The latter has a positive impact on intrapreneurship.Research limitations/implicationsThis article has some theoretical and methodological limitations like any other academic work. They would be interesting to address in future research. In this way, it is possible to empirical examine the variables of intrapreneurship, internal communication and happiness (Ravina-Ripoll et al., 2021c). The first is the study's cross-sectional design and data collection by a non-probabilistic sample, carried out in a single source. Both aspects mean that our study is not free of corresponding biases;this may result in the findings of the present work not being statistically correct. The second derives from the absence in the literature of structural equation modelling studies that analyse the constructs that make up the object of this academic work in a multidimensional way. However, although an influence I show between the variables, it is recommended to take the data with discretion. There is still a need for more empirical evidence to support these relationships before generalised results can be presumed. Despite the remarkable progress made in recent years in the literature on the three dimensions of this article, few scientific studies examine inferentially how internal communication and intra-entrepreneurship influence employees' happiness at work in today's digital society. The authors of this academic work consider it attractive for future research to address the analysis of internal communication strategic management models. It is a robust driver of intra-entrepreneurship and employee happiness in organisations (Galván-Vela et al., 2022a). In conclusion, from this heuristic perspective, companies can improve, on the one hand, their competitive position in the market. Their managers must cultivate an organisational culture that emphasises internal communication as a catalyst for innovation, employee loyalty, and productive efficiency. On the other hand, companies will be able to invigorate their corporate image to face the significant challenges in the globalised economy, thus to become sustainable, humane, ecological intra-entrepreneurial corporations (Galván-Vela et al., 2021a). It may lead to a more social, inclusive, prosperous and egalitarian ecosystem. In this way, it makes the culture of organisations around the pillars of happiness management, social marketing and the Sustainable Development Goals shine (Galván-Coronil et al., 2021).Practical implicationsThis section does not attempt to argue that internal communication and intrapreneurship constitu e two intangible resources that improve organisations' productivity and collective happiness (Lee and Kim, 2022). However, it is necessary to clarify that the results achieved in this academic study show two fundamental aspects. The first is to invite managers of companies in the post-Covid-19 era to cultivate a culture based on happiness management. It makes internal communication a fast vehicle that exponentially boosts intrapreneurship, among other things (Castillo-Abdul et al., 2021). To this end, their strategic management models must carry out a diametrical shift in their innovation and internal communication actions. On the one hand, it allows for building loyalty among their creative talent. It does this by creating an organisational climate that encourages interpersonal relationships, the spirit of teamwork, collaborative participation, and disruptive thinking (Thelen and Formanchuk, 2022). On the other hand, promoting an ethical, assertive and empathetic leadership style proactively stimulates the commitment, trust and passion for the work of all members of the company (Men and Yue, 2019). The second is to emphasise implementing a constructive, friendly and positive intra-organisational language. In this way, it is dynamising the collective happiness of its human capital through the figure of the Chief Happiness (Jiménez-Marín et al., 2021b).Originality/valueIntrapreneurship, internal communication and happiness at work are topics of great interest in academic agendas in recent years. It is basically because these three dimensions, individually or jointly, have positive effects on the productivity of organisations. However, no research flow evidences our theoretical model proposed in this article. Therefore, there is a need for future studies that advance the literature in the area of business. In this way, we will have more data on how these constructs affect the life of organisations in the post-Covid 19 eras.

ABSTRACT

The main tools for allowing customers to communicate openly and transparently with the company and other stakeholders are their electricity bills. However, last year due to pandemics, some residents petitioned the Madras high court claiming TANGEDCO's technique to measure power was arbitrary and unreasonable during the lockdown that COVID provoked. This was done amid complaints about excessive electricity bills. When compared to bills from other states, TANGEDCO's white meter card for energy bills is found to provide insufficient information on use and rates, according to a survey by the certain associations. Power bills urgently need to be redesigned to include comprehensive billing details and accurate assessments of electricity consumption from closed homes or homes in restricted zones. [4] We proposed and designed a Smart Home Energy Meter Monitoring System to solve this crisis. It consists of three systems. First system: Customized built energy meter with LCD. [6] Second system: Wi-Fi module with the Microcontroller (ATMega328P) and an alert system. Third system: Database (MySQL database). [12] The quantity of power used by the device is measured by an energy meter user and every two months, the final reading of the power consumption is taken by the micro controller where the electricity bill calculation program has been pre-programmed to give the value of power consumed during the two months and amount to be paid by the user and [4] It will be shown on the Energy Meter's LCD. The micro controller with a built-in Wi-Fi module (ESP8266) will send these displayed data to the service provider's database. [2] An alert system has been added to counteract the hefty usage and electricity bills to create awareness to the consumer about the slab-wise tariffs increase in the per-unit cost data that has been set by TANGEDCO. [10] The alert has been set in a way that the consumer receives a message for every 200 unit usage of power. The third system is a database created using MySQL database to transport the data to the service provider. © 2022 IEEE.

ABSTRACT

Covid-19 outbreak had changed the people behavior toward electricity usage. This pandemic has fasten the transformation of PLN business process, from supply driven into demand driven business. PLN UP3 Lhokseumawe challenged to improve their services and energy transaction. In order to achieve the goals, it is suggested to improve services of new installment for 3-phase energy meter without expansion. Previously the task can only be done with at least 3 days of works. It was mainly due to many steps required to assemble the metering box. This paper proposed the usage of portable smart energy meter that can replace the metering box during assembly phase. The device can also accommodate several power options that can adjust with the customer's current plan. Thus, by implementing the portable box, customers can enjoy the electricity by the same day instead of previous 3 days. The result from energy meter showed that based on Ibase, with load of 100%, 75%, 50% and 25% resulted in 0.0538%, 0.0619%, 0.0139% and 0.0335% respectively. The result from CT Ratio error with 100/5, 150/5, 200/5, 250/5 and 300/5 showed as -0.26%, -0.32%, -0.23%, 0.15% and -0.17% respectively. The result was in range which mean that smart energy meter portable was tested on good condition. The use of this device can shorten the service delivery time, especially on new installment for 3-phase energy meter without expansion of power between 53 to 197 kVA. This solution is advantageous both for PLN customers and the corporation itself. © 2022 IEEE.

ABSTRACT

Airport emissions have received increased attention because of their impact on atmospheric chemical processes, the microphysical properties of aerosols, and human health. At present, the assessment methods for airport pollution emission mainly involve the use of the aircraft emission database established by the International Civil Aviation Organization, but the emission behavior of an engine installed on an aircraft may differ from that of an engine operated in a testbed. In this study, we describe the development of a long-path differential optical absorption spectroscopy (LP-DOAS) instrument for measuring aircraft emissions at an airport. From 15 October to 23 October 2019, a measurement campaign using the LP-DOAS instrument was conducted at Hefei Xinqiao International Airport to investigate the regional concentrations of various trace gases in the airport’s northern area and the variation characteristics of the gas concentrations during an aircraft’s taxiing and take-off phases. The measured light path of the LP-DOAS passed through the aircraft taxiway and the take-off runway concurrently. The aircraft’s take-off produced the maximum peak in NO2 average concentrations of approximately 25 ppbV and SO2 average concentrations of approximately 8 ppbV in measured area. Owing to the airport’s open space, the pollution concentrations decreased rapidly, the overall levels of NO2 and SO2 concentrations in the airport area were very low, and the maximum hourly average NO2 and SO2 concentrations during the observation period were better than the Class 1 ambient air quality standards in China. Additionally, we discovered that the NO2 and SO2 emissions from the Boeing 737–800 aircraft monitored in this experiment were weakly and positively related to the age of the aircraft. This measurement established the security, feasibility, fast and non-contact of the developed LP-DOAS instrument for monitoring airport regional concentrations as well as NO2 and SO2 aircraft emissions during routine airport operations without interfering with the normal operation of the airport.

ABSTRACT

Global climate change and COVID-19 have changed our social and business life. People spend most of their daily lives indoors. Low-cost devices can monitor indoor air quality (IAQ) and reduce health problems caused by air pollutants. This study proposes a real-time and low-cost air quality monitoring system for smart homes based on Internet of Things (IoT). The developed IoT-based monitoring system is portable and provides users with real-time data transfer about IAQ. During the COVID-19 period, air quality data were collected from the kitchen, bedroom and balcony of their home, where a family of 5 spend most of their time. As a result of the analyzes, it has been determined that indoor particulate matter is mainly caused by outdoor infiltration and cooking emissions, and the CO2 value can rise well above the permissible health limits in case of insufficient ventilation due to night sleep activity. The obtained results show that the developed measuring devices may be suitable for measurement-based indoor air quality management. In addition, the proposed low-cost measurement system compared to existing systems;It has advantages such as modularity, scalability, low cost, portability, easy installation and open-source technologies.

ABSTRACT

The Single European Sky Air Traffic Management Research (SESAR) program aims at modernizing and harmonizing the European airspace, which currently has a strongly fragmented character. Besides turbulence and convection, in-flight icing is part of SESAR and can be seen as one of the most important meteorological phenomena, which may lead to hazardous flight conditions for aircraft. In this study, several methods with varying complexities are analyzed for combining three individual in-flight icing forecasts based on numerical weather prediction models from Deutscher Wetterdienst, Météo-France, and Met Office. The optimal method will then be used to operate one single harmonized in-flight icing forecast over Europe. As verification data, pilot reports (PIREPs) are used, which provide information about hazardous weather and are currently the only direct regular measure of in-flight icing events available. In order to assess the individual icing forecasts and the resulting combinations, the probability of detection skill score is calculated based on multicategory contingency tables for the forecast icing intensities. The scores are merged into a single skill score to give an overview of the quality of the icing forecast and enable comparison of the different model combination approaches. The concluding results show that the most complex combination approach, which uses iteratively optimized weighting factors for each model, provides the best forecast quality according to the PIREPs. The combination of the three icing forecasts results in a harmonized icing forecast that exceeds the skill of each individual icing forecast, thus providing an improvement to in-flight icing forecasts over Europe.

ABSTRACT

Aptamers represent the next frontier as biorecognition elements in biosensors thanks to a smaller size and lower molecular weight with respect to antibodies, more structural flexibility with the possibility to be regenerated, reduced batch-to-batch variation, and a potentially lower cost. Their high specificity and small size are particularly interesting for their application in optical biosensors since the perturbation of the evanescent field are low. Apart from the conventional plasmonic optical sensors, platforms based on silica and plastic optical fibers represent an interesting class of devices for point-of-care testing (POCT) in different applications. The first example of the coupling between aptamers and silica optical fibers was reported by Pollet in 2009 for the detection of IgE molecules. Six years later, the first example was published using a plastic optical fiber (POF) for the detection of Vascular Endothelial Growth Factor (VEGF). The excellent flexibility, great numerical aperture, and the large diameter make POFs extremely promising to be coupled to aptamers for the development of a sensitive platform easily integrable in portable, small-size, and simple devices. Starting from silica fiber-based surface plasmon resonance devices, here, a focus on significant biological applications based on aptamers, combined with plasmonic-POF probes, is reported.

ABSTRACT

Entrepreneurial orientation influences the development of organizations and the need to undertake it implies assuming certain risks for entrepreneurs who must respond to the constant dynamism of the business world in search of new opportunities for success. The objective was to find the conditions for and against the entrepreneurial orientation that exists in the State of Hidalgo, through the opinion of 300 experts in entrepreneurship. A measuring instrument was used and adapted in 2019 by the National Network of MSMEs (micro, small and medium enterprises) of the Consortium of Mexican Universities (CUMEX), based on the Global Entrepreneurship Monitor and the information was collected through an online questionnaire. The main results show the need to strengthen entrepreneurial orientation, improving aspects regarding financing, government programs, the opening of the internal market and regulations, and social and cultural issues;likewise, an important finding is that the generalized perception of this phenomenon is more positive than if each dimension is analyzed in a particular way, along with the factors that compose it. This study can contribute to the generation of a better entrepreneurial culture that encourages the creation of new businesses.

ABSTRACT

Background: Burnout is a state of vital exhaustion that has a high global prevalence among dental professionals. Yet the early diagnosis of this syndrome is challenging due to its multidimensional nature. Aim: To assess burnout and its relation to emotional dysregulation and social cognition among undergraduate dental students. Methods: We mailed 148 self-administered questionnaires to all interns and undergraduate dental students belonging to the College of Dentistry’s female campus at King Khalid University, Saudi Arabia. A questionnaire was designed comprising three measuring instruments of psychological inventories to assess work-related stress, namely, burnout (Copenhagen burnout inventory questionnaire (CBI)), emotional dysregulation (emotion regulation questionnaire (ERQ)), and social cognition (interpersonal reactivity index (IRI)). We examined the difference in burnout between two cohorts (interns and undergraduates) using Student’s ‘t’ test and the association between emotional regulation/social cognition domains using Pearson’s correlation. Results: Among the participants, around 70% obtained higher scores than the cut-off points for personal and work-related domains in both groups. There was no statistically significant difference in burnout domain between the two cohorts (p > 0.05;Cohen d < 0.3). A negative correlation existed between burnout and emotion regulation, i.e., higher burnout score is associated with lesser cognitive reappraisal and more expressive suppression (CBI—personal burnout r = −0.251;r = −0.220 respectively). Social cognitive scores had various associations among interns and undergraduates, with personal distress being significantly associated with greater burnout levels among both groups (p < 0.05). Conclusions: The present study revealed significantly elevated burnout levels among both interns and undergraduate students. Emotional dysfunction and social cognition assessment can be a valuable adjunct in identifying this erosive syndrome. Early recognition and primordial prevention targeting burnout are strongly recommended.

ABSTRACT

The outbreak of Corona Virus Disease 2019 (Covid 19) cases that occurred from 2020 until now limits the current maximum allowed room capacity, which is only around 25% to 50% of the maximum room capacity. The purpose of this study is to design a device that can detect temperature and limit room capacity automatically as an effort to prevent the transmission of the covid 19 virus. In designing a room capacity measuring device and an atmega328 microcontroller-based body temperature detector with a viewer on an android smartphone. The ultrasonic sensor HC-SR04 is used to measure the capacity of the room to determine the number of people entering and leaving. Then this tool also uses the MLX90614 sensor to detect the body temperature of everyone who wants to enter with the temperature conditions below 38°C. When both sensors have worked according to their functions, the doorstop can be opened. The results of the data obtained on each sensor will be sent to the microcontroller as a control center on a system so that it can be displayed on the LCD and using an additional device, namely esp8266 as a wifi communication module. After testing it can be concluded that the tool works well. The comparison of the results of the MLX90614 sensor with a standard tool. The data obtained is quite accurate with maximum error only 2.2% with the comparison tool.

ABSTRACT

It is essential to measure and monitor the intravenous (IV) infusion rate of inpatients. Medical staff monitor the IV infusion rate continually to ensure that a constant value is maintained. Developing an IV infusion monitoring system can help alleviate the workload of medical staff. Therefore, this paper proposes a method based on optical sensors, in conjunction with the Internet of Things, to overcome the challenges of IV therapy. To increase the sensitivity of the system, both optical sensors and load cells are used to compensate for their disadvantages. Our system yielded accuracies of 87.9% and 89.9% under horizontal and vertical motion conditions, respectively. The proposed system can send notifications to nursing stations regarding the residual IV fluid, current infusion rate, and expected end time, which can be monitored remotely by medical staff. Furthermore, this system can help prevent possible medical accidents during fluid treatment.
