Two-Electrode ECG for Ambulatory Monitoring with Minimal Hardware Complexity
Authors: Babusiak Branko , Borik Stefan , Smondrk Maros
Published: April 2020

This article introduces a two-electrode ground-free electrocardiogram (ECG) with minimal hardware complexity, which is ideal for wearable battery-powered devices. The main issue of ground-free measurements is the presence of noise. Therefore, noise suppression methods that can be employed for a two-electrode ECG acquisition system are discussed in detail. Experimental measurements of a living subject and patient simulator are used to investigate and compare the performance of the three proposed methods utilizing the ADS1191 analogue front-end for biopotential measurements. The resulting signals recorded for the simulator indicate that all three methods should be suitable for suppressing power-line noise. The Power Spectral Density (PSD) of the signals measured for a subject exhibits differences across methods; the signal power at 50 Hz is −28, −24.8, and −26 dB for the first, second, and third method, respectively. The digital postprocessing of measured signals acquired a high-quality ECG signal comparable to that of three-electrode sensing. The current consumption measurements demonstrate that all proposed two-electrode ECG solutions are appropriate as a battery-powered device (current consumption < 1.5 mA; sampling rate of 500 SPS). The first method, according to the results, is considered the most effective method in the suppression of power-line noise, current consumption, and hardware complexity.
Facial Expressions Recognition for Human–Robot Interaction Using Deep Convolutional Neural Networks with Rectified Adam Optimizer
Authors: Melinte Daniel Octavian , Vladareanu Luige
Published: April 2020

The interaction between humans and an NAO robot using deep convolutional neural networks (CNN) is presented in this paper based on an innovative end-to-end pipeline method that applies two optimized CNNs, one for face recognition (FR) and another one for the facial expression recognition (FER) in order to obtain real-time inference speed for the entire process. Two different models for FR are considered, one known to be very accurate, but has low inference speed (faster region-based convolutional neural network), and one that is not as accurate but has high inference speed (single shot detector convolutional neural network). For emotion recognition transfer learning and fine-tuning of three CNN models (VGG, Inception V3 and ResNet) has been used. The overall results show that single shot detector convolutional neural network (SSD CNN) and faster region-based convolutional neural network (Faster R-CNN) models for face detection share almost the same accuracy: 97.8% for Faster R-CNN on PASCAL visual object classes (PASCAL VOCs) evaluation metrics and 97.42% for SSD Inception. In terms of FER, ResNet obtained the highest training accuracy (90.14%), while the visual geometry group (VGG) network had 87% accuracy and Inception V3 reached 81%. The results show improvements over 10% when using two serialized CNN, instead of using only the FER CNN, while the recent optimization model, called rectified adaptive moment optimization (RAdam), lead to a better generalization and accuracy improvement of 3%-4% on each emotion recognition CNN.

The aim of this work was to develop multimodal anthropomorphic breast phantoms suitable for evaluating the imaging performance of a recently-introduced Microwave Imaging (MWI) technique in comparison to the established diagnostic imaging modalities of Magnetic Resonance Imaging (MRI), Ultrasound (US), mammography and Computed Tomography (CT). MWI is an emerging technique with significant potential to supplement established imaging techniques to improve diagnostic confidence for breast cancer detection. To date, numerical simulations have been used to assess the different MWI scanning and image reconstruction algorithms in current use, while only a few clinical trials have been conducted. To bridge the gap between the numerical simulation environment and a more realistic diagnostic scenario, anthropomorphic phantoms which mimic breast tissues in terms of their heterogeneity, anatomy, morphology, and mechanical and dielectric characteristics, may be used. Key in this regard is achieving realism in the imaging appearance of the different healthy and pathologic tissue types for each of the modalities, taking into consideration the differing imaging and contrast mechanisms for each modality. Suitable phantoms can thus be used by radiologists to correlate image findings between the emerging MWI technique and the more familiar images generated by the conventional modalities. Two phantoms were developed in this study, representing difficult-to-image and easy-to-image patients: the former contained a complex boundary between the mammary fat and fibroglandular tissues, extracted from real patient MRI datasets, while the latter contained a simpler and less morphologically accurate interface. Both phantoms were otherwise identical, with tissue-mimicking materials (TMMs) developed to mimic skin, subcutaneous fat, fibroglandular tissue, tumor and pectoral muscle. The phantoms’ construction used non-toxic materials, and they were inexpensive and relatively easy to manufacture. Both phantoms were scanned using conventional modalities (MRI, US, mammography and CT) and a recently introduced MWI radar detection procedure called in-coherent Multiple Signal Classification (I-MUSIC). Clinically realistic artifact-free images of the anthropomorphic breast phantoms were obtained using the conventional imaging techniques as well as the emerging technique of MWI.
Designing a Smart Bath Assistive Device Based on Measuring Inner Water Temperature for Bathing Temperature Monitoring
Authors: Wei Qun , Kang So-Myoung , Lee Jae Ho
Published: April 2020

Today, taking a bath is not only a means to keep clean, but also to reduce fatigue and stress. However, taking a bath with hot water for a long time can also be dangerous, leading to scalding or even a heart attack. To prevent these risks, several studies based on measuring bio-signals have been conducted, but due to high prices, difficulty of use, and restricted functions, these studies’ recommendations cannot be easily adopted by the public. Therefore, developing accurate methods to measure bathing temperature and bathing time should be the most direct approach to solve these problems. In this study, a smart bath assistive device based on an inner water temperature measurement function is proposed. Prior to development of the device, a bathing environment was emulated with six temperature sensors affixed to different depths to find the optimal depth for measuring bathing temperature. According to the measurement results, the device was designed in a mushroom shape with the cap part floating on the water’s surface and housing the electronic components, and temperature sensors within the stem part were immersed in the water approximately 5 cm below the surface to measure the inner water temperature. Due to the low-power consuming Advanced RISC Machine (ARM) processor and waterproof design, the device is able to float in hot water and monitor the bathing temperature variation over a long period of time. The device was compared alongside a commercial analog bathing thermometer to verify the performance of temperature measurements. In addition, a compensation algorithm was developed and programmed into the device to improve the accuracy of measurements. Processed data is transmitted by Bluetooth to a dedicated Android app for data display and storage. The final results show that the proposed device is highly accurate and stable for monitoring bathing temperature.

Authors: Zeng Lingwei , Wang Hanfeng , Li Ying , He Xuhui
Published: April 2020

Digital image projection (DIP) with traditional vertical calibration cannot be used for measuring the water droplets/film on a curved surface, because significant systematic error will be introduced. An improved DIP technique with normal calibration is proposed in the present paper, including the principles, operation procedures and analysis of systematic errors, which was successfully applied to measuring the water droplets/film on a curved surface. By comparing the results of laser profiler, traditional DIP, improved DIP and theoretical analysis, advantages of the present improved DIP technique are highlighted.

Published: April 2020

The paper presents tools to model low speed airflow coming from a turbulent machine. This low speed flow have instabilities who generate noise disturbances in the environment. The aim of the study proposed in this paper, is the using of cyclostationary tools with audio signals to model this airflow and detect the noisy frequencies to eliminate this noise. This paper also deals with the extraction in real time of the frequency corresponding to the noise nuisance. This extraction makes it possible to build a software sensor. This software sensor can be used to estimate the air flow rate and also to control a future actuator which will reduce the intensity of the noise nuisance. This paper focuses on the characteristic of the sound signal (property of cyclostationarity) and on the development of a software sensor. The results are established using an experimental setup representative of the physical phenomenon to be characterised.
Kenya’s Over-Reliance on Institutionalization as a Child Care and Child Protection Model: A Root-Cause Approach
Authors: Chege Njeri , Ucembe Stephen
Published: April 2020

Institutionalization of children who are deprived of parental care is a thriving phenomenon in the global South, and has generated considerable concern both nationally and internationally, in the last two decades. In Kenya, the number of children growing up in live-in care institutions has been growing ever since the country’s early post-independence years. Although legislative and regulatory measures aimed at child protection have been in place for a number of years now, and the national government appears to be standing by the commitment it expressed in recent times to implement care reform which encompasses de-institutionalization, the national child protection system remains very dependent on institutional care. Against the backdrop of a global and national movement towards de-institutionalization of child care and child protection, in this paper we tease out the range of factors reinforcing Kenya’s over-reliance on live-in institutions as a child care and child protection model. Numerous factors—structural, political, economic, socio-cultural, and legal—contribute to the complexity of the issue. We highlight this complexity, bringing together different angles, while pointing out the interests of the different stakeholders in reinforcing institutional care. We argue that the sustainability, efficiency and effectiveness of the intended change from institutional care to alternative family-based care requires that a root-cause approach be adopted in addressing the underlying child care and child protection issues.

Published: April 2020

Background: To try out the feasibility of presenting the health status of children 6 to 12 years old by using radar plots. Methods: With data from the Health Oriented Pedagogical Project (HOPP) we have described the health status for 1340 children aged 6 to 12 years. We collected or calculated: stature, body mass, waist circumference, waist to height ratio, high density lipoprotein (HDL) and total cholesterol concentration, blood pressure, accelerometer assessed physical activity, endurance interval running performance, and quality of life. Pertinent variables were presented through a radar plot for both individual cases and groups. Results: The boys showed better endurance and recorded more moderate to vigorous physical activity than the girls. The activity level dropped from age 6 to age 12 for both sexes. The girls showed a lower systolic blood pressure compared with boys. Self-rated quality of life was high among boys and girls. Conclusions: This cohort showed good health and the radar plot made it easy to visualise health status for groups and individuals.
The Tax Incentives in the IVTM and “Eco-Friendly Cars”: The Spanish Case
Authors: Náñez Alonso Sergio Luis
Published: April 2020

This article describes research that was carried out regarding the tax incentives in Spain associated with the “eco-friendly car,” which are reflected in its share of taxes on motor-driven vehicles. The study focused on the electric vehicle, the hybrid, and the liquefied petroleum gas vehicle. First, the current regulatory framework was addressed. The maximum bonus limits were considered, as well as how each of 68 cities examined the incentives. The qualitative and quantitative differences among the Spanish cities were discussed. Next, the annual tax savings on the Tax on motor vehicles (IVTM) quota were calculated, and the differences in the tax savings depending on the municipality and type of vehicle were noted, as well as the temporal duration of the bonus. Finally, the average tax savings were calculated based on the type of vehicle, power and municipality. It is clear that, although the tax incentives are positive, they must be complemented by other measures if the public authorities in Spain want to achieve a change in mentality and an increase in the acquisition of “eco-friendly cars” that eliminate pollutants (powered by the combustion of gasoline or diesel).
Efficiency Evaluation of Cultural Services in the Czech Republic via Multi-Criteria Decision Analysis
Authors: Vavrek Roman , Bečica Jiří
Published: April 2020

Culture is an irreplaceable means of transferring information between generations. The development of culture, the cultural environment, and the effect of culture exist over the long term. The results are not shown immediately, whereas the economics of subjects of this area (including theatres) are subject to public control. Public control forces these entities to use public finances efficiently, economically, and effectively. A sample of 11 indicators showing techniques and financial efficiency was chosen to conduct a complex evaluation of the economy of Czech theatres. The importance of the indicators was set by three objective methods used in combination by the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) for the evaluation of management. We show significant differences among the results; in our opinion, it is not possible to exactly set the best method that could be applied in general. Every method can potentially serve as a tool for complex comparison among homogeneous groups of theatres of the Czech Republic, depending on the preferences of their founder, in the public sector such as a municipality, region, or state.
TRIZ-Based Guidelines for Eco-Improvement
Authors: Russo Davide , Spreafico Christian
Published: April 2020

This paper proposes a set of Eco-guidelines for supporting designers in developing new greener products and processes. The first requirement that a guideline should have is to be sufficiently general to cover every kind of problem and at the same time sufficiently specific to bring the user closer to the solution without requiring too much personal inspiration. This balance was searched by adopting one of the most known systematic innovation techniques: TRIZ (Russian acronym of Theory of Inventive Problem Solving). In the literature, there are many examples of integrations between Eco-guidelines and problem-solving methods, but the solutions that are suggested, however effective, are not necessarily eco-friendly. To overcome this problem, the authors propose a rigorous ontology indicating how to apply a specific problem-solving strategy onto a specific part of the problem, trying to make the user aware of the environmental consequences of his design changes. The result of this work is a set of 59 guidelines. The article explains the birth of each guideline, the way in which they were adapted with respect to the known technique, and the motivation for which they should generate greener solutions, in light of the results of an experiment involving engineering students in real industrial cases.

Authors: Muñoz López Natalia , Santolaya Sáenz Jose Luis , Biedermann Anna , Serrano Tierz Ana
Published: April 2020

The development of product–service systems (PSS) is currently considered a promising solution to the challenge of sustainability. Nevertheless, the sustainability of these systems has not been systematically assessed and there is a need to develop more guiding principles. In this work, an approach based on the flows between product and service systems is used to facilitate both the definition of PSS boundaries and the identification of links between the systems involved. In addition, the life cycle sustainability assessment (LCSA) method is applied to simultaneously quantify environmental, economic and social impacts. Two cases are analysed. First, the production process of cow´s milk, in which a veterinary service is required, is studied using data measured from a dairy farm. Next, the sustainability of a clothing retail service taking, into account that a construction product is involved in its creation stage, is evaluated. In each PSS specific life cycle, stages are analysed, a functional unit referred to both products and services is defined, and quantitative indicators are selected to assess each sustainability dimension. The category of workers is selected to evaluate social aspects. The relative incidence of each system is evaluated and the impacts of different factors on the PSS sustainability are analysed.
Accounting Treatment of R&D for Environmentally Responsible Firms: Evidence from South Korea
Authors: Kim Suyon , Lee Jaehong
Published: April 2020

The purpose of this paper is to investigate the relationship between corporate environmental responsibility (CER) and R&D accounting treatment. Using firms listed in the Korea Stock Exchange (KSE) market between the years 2014 and 2018, this study not only investigates this relationship but also expands upon CER activities in various aspects, such as environmental performance strategy, environmental performance organization, and environmental shareholders. Furthermore, the positive association between various CER activities and R&D capitalization is significant in a highly competitive market. This relationship is robust with an alternative measure of CER activities and firm-fixed effects. This result implies that firms participating in CER activities focus on sustainable commercial success, unlike other firms.
Sustainable Risk Assessment through the Analysis of Financial Losses from Third-Party Damage in Bridge Construction
Authors: Ahn Sungjin , Kim Taehui , Kim Ji-Myong
Published: April 2020

Due to the recent introduction of innovative construction methods and technologies, construction projects increasingly require sustainability in their high degrees of specialization and complex work processes. This is due to a wide variety of new risk factors associated with construction projects that can lead to extensive and severe damage. When an accident occurs during a construction project, it can cause material, property, or bodily damage not only within the actual construction site but also outside, affecting third parties. This study analyzed the record of such third-party damage and the subsequent financial losses in bridge construction management, to identify the objective and quantified relationship of risk indicators related to the damage and losses. In order to assess the actual losses in construction projects, we adopted the loss claim payout data as recorded and provided by a major Korean insurance company, and conducted a multiple regression analysis to identify the loss indicators and to develop a loss estimation model. In this study, the analysis of the data indicated that the superstructure type, the foundation type, floods, and company ranking by the amount of the contract were the four statistically significant risk indicators that affected financial losses from third-party damage, among the nine variables used as independent variables, which included the superstructure type, foundation type, superstructure construction method, maximum span length, floods, typhoons, total construction cost, total construction period, and company ranking. As this study focused on identifying the risk factors and producing a loss assessment model quantified in numerical values, the results provide important references for assessing and minimizing the risks to third parties and the consequential financial losses in bridge construction, while promoting sustainability objectives.
Research as a Base for Sustainable Development of Universities: Using the Delphi Method to Explore Factors Affecting International Publishing among Vietnamese Academic Staff
Authors: Tran Trung , Trinh Thao-Phuong-Thi , Le Cuong-Minh , Hoang Linh-Khanh , Pham Hiep-Hung
Published: April 2020

In recent years, the Vietnamese government has put significant effort into the internationalization of research in the higher education system via the use of international publications (i.e., publications indexed by citation databases such as ISI Web of Science and Scopus) in evaluating their academic staff and doctoral students. Academic staff in Vietnam, who traditionally have low numbers of international publications, have thus been pushed to improve their competencies in order to meet the new requirements for research productivity. However, we have little understanding of the factors influencing international publication as perceived by Vietnamese academic staff. This study aims to fill the gap by using the Delphi method. Academic staff with at least one international publication were invited, via purposeful sampling, to participate in a two-round Delphi survey. The survey revealed 14 key factors, which were further classified into three dimensions: “policy-related factors,” “capability-related factors,” and “networking-related factors”. These factors were the key determinants in the success of international publishing, according to the study participants. The findings provide implications for policymakers and university leaders for enhancing the research capacities of Vietnamese universities, forming a basis for the sustainable development of the higher education sector in Vietnam.
Similarities of Flow and Heat Transfer around a Circular Cylinder
Authors: Ma Hao , Duan Zhipeng
Published: April 2020

Modeling fluid flows is a general procedure to handle engineering problems. Here we present a systematic study of the flow and heat transfer around a circular cylinder by introducing a new representative appropriate drag coefficient concept. We demonstrate that the new modified drag coefficient may be a preferable dimensionless parameter to describe more appropriately the fluid flow physical behavior. A break in symmetry in the global structure of the entire flow field increases the difficulty of predicting heat and mass transfer behavior. A general simple drag model with high accuracy is further developed over the entire range of Reynolds numbers met in practice. In addition, we observe that there may exist an inherent relation between the drag and heat and mass transfer. A simple analogy model is established to predict heat transfer behavior from the cylinder drag data. This finding provides great insight into the underlying physical mechanism.

Published: April 2020

Due to the prevalence of Human Immuno-deficiency Virus/Acquired Immuno-Deficiency Syndrome (HIV/AIDS) infection in society and the importance of preventing the spread of this disease, a mathematical model for sexual transmission of HIV/AIDS epidemic with asymptomatic and symptomatic phase and public health education is stated as a symmetric system of differential equations in order to reduce the spread of this infectious disease. It is demonstrated that public health education has a considerable effect on the prevalence of the disease. Moreover, the cost of education is very high and for this reason, a cost-optimal control is applied to provide the best possible combination of the parameters corresponding to education in controlling the spread of the disease by means of the Genetic Algorithm (GA) and Simulated Annealing (SA).

Published: April 2020

The purpose of the present investigation was to examine the acute effects of whole body vibration (WBV) on isometric mid-thigh pull force–time curve (FTC) characteristics. Eleven recreationally trained subjects were randomly assigned to three treatment conditions: sham no vibration protocol (T1), vibration protocol 30 Hz 2–4 mm amplitude (T2), and vibration protocol 30 Hz 2–4 mm (T3). After completing a standardized warm-up, the subject stood on a vibration platform with the knee at a 120° angle and performed one of the three interventions. Each treatment condition required the subject to stand on the platform for thirty-second treatments, each separated by thirty seconds of recovery. Five minutes after the completion of the treatment conditions, the subjects performed the isometric mid-thigh pull. All FTCs were analyzed with standardized procedures for peak force (PF) and peak rate of force development (PRFD). A 1 × 3 repeated measures analysis of variance (ANOVA) was used to compare the three treatments. Additionally, coefficients of variance (CV), as well as intraclass and interclass correlations, were performed. There were no significant differences (p > 0.05) for any of the FTC analyses performed in this investigation. The CV and the 95% confidence interval (CI) indicate that the WBV protocol resulted in trivial changes in PF and beneficial changes in PRFD. A 30 Hz 2–4 mm amplitude WBV does not result in a significant increase in isometric mid-thigh pull performance.

Petroleum geochemistry of the deepened Lopra-1/1A re-entry well, Faroe Islands
Authors: Bojesen-Koefoed Jørgen A. , Nytoft H. Peter
Published: April 2020

The Lopra-1/1A re-entry well was drilled as a stratigraphic test with no immediate exploration objectives. Hence, petroleum geochemical studies were of limited extent, and restricted to non-destructive analyses. The presence of natural petroleum hydrocarbons could not be confirmed with certainty, but hydrocarbons extracted from the hydrochloric acid solute of a calcite vug present in RSWC #1 (3543 m), may represent indigenous petroleum since hydrocarbon-bearing fluid inclusions have been reported from the same sample. These hydrocarbons show some similarities to petroleum generated from the Upper Jurassic – Lower Cretaceous Kimmeridge Clay type source rocks present in surrounding areas. Except for this sample, the results generally show the presence of a variety of contaminants of different origins such as ‘naturally greasy fingers’ (squalene and cholesterol), cosmetics such as chap stick or hand lotion (e.g. esters such as butyl-stearate, stearyl-palmitate, vitamin A), plasticisers (phthalates), diesel oil and ‘pipe dope’.

Authors: Meroño Saura María Antonia , Nájera Pérez María Dolores , Ayala de la Peña Francisco , Rodríguez Martínez Taida María , Fernández Zamora Celia , León Villar Josefa
Published: April 2020

Antecedentes y objetivo: El uso de medicamentos en condiciones diferentes a las autorizadas es el uso de medicamentos en condiciones distintas a las incluidas en su ficha técnica. El objetivo del presente trabajo es analizar las solicitudes de medicamentos fuera de ficha técnica y sus resultados, realizadas por el Servicio de Oncología y Hematología en un hospital de segundo nivel.

Materiales y métodos: Se realizó un estudio observacional retrospectivo de todas las peticiones de fármacos “off label” recibidas por el Servicio de Farmacia. Los medicamentos se clasificaron según impacto económico, una clasificación propia según el tipo de fármaco y motivo de petición y según su grado de evidencia. Se analizó para cada solicitud los datos demográficos, de diagnóstico y de tratamiento de los pacientes. Se presenta un seguimiento de los efectos adversos, mediana de supervivencia libre de progresión y mediana de supervivencia global.

Resultados: Se aprobaron 85 solicitudes de tratamiento. La mayoría de tratamientos fueron de alto impacto dirigidos principalmente a patologías raras y últimas opciones de tratamiento. Un 22% de las solicitudes tenían alto grado de evidencia. La media de supervivencia libre de progresión (SLP) y la supervivencia global (SG) fueron de 6,6 (IC 95% 5,2-8) y 9,7 meses (IC95% 8,2-11,2). Un 18,7% pacientes presentaron toxicidad de grado 3-4 al recibir el tratamiento.

Conclusiones: A pesar de la heterogeneidad de las patologías, y la baja evidencia, los resultados obtenidos en SLP y SG, junto a la escasa toxicidad, nos obliga a seguir avanzando en la evaluación de este tipo de tratamientos.

Objetivo: Describir los diagnósticos histopatológicos a partir de los casos las pacientes con cáncer de mama que fueron llevadas a resección de nódulos pulmonares en el Instituto Nacional de Cancerología (INC).

 Materiales y métodos: Se desarrolló un estudio tipo serie de casos donde se describen las características clínicas, histológicas y anatomopatólogicas de un grupo de pacientes con diagnóstico confirmado de cáncer de mama de novo o que durante su enfermedad presentaron nódulos pulmonares que requirieron resección quirúrgica mediante cuña pulmonar o lobectomía en el INC, entre 1 de enero de 2015 y el 30 de abril de 2018.

 Resultados: En el periodo de estudio se realizaron 225 resecciones en cuña pulmonar y lobectomías de las cuales y se seleccionaron 55 casos de los cuales el 69.1% fueron de origen neoplásico 26 (47.3%) fueron metástasis de cáncer mama, 9 (16.4%) segundo primario pulmonar y 1 (1.8%) paciente tenía concomitantemente cáncer primario pulmonar y una metástasis de mama. Otras 2 (3.6%) pacientes tenían metástasis de otros órganos, uno de recto y uno de tiroides, mientras que las 17 (30.9%) pacientes restantes presentaron reporte de lesiones pulmonares benignas en la anatomía patológica

Conclusión: La presencia de nódulos pulmonares en pacientes con cáncer de mama no siempre son secundarias a enfermedad metastásica en pulmón; pueden existir otras etiologías como cancer primario pulmonar, metástasis de otros órganos, tumores benignos o infecciones. Conocer la etiología de los nódulos pulmonares en pacientes con cáncer de mama es determinante para evaluar las opciones terapéuticas.

The purpose of this study was to be able to utilized the dog’s manure into making it a sustainable product that could further withstand the signs of times (specifically earthquakes). This Qualitative-Quantitative study (Exploratory Research Design) investigation firstly interviewed relevant participants that has something to say. In the results of the study, it was found out that hollow blocks with an additive of dog’s manure and polystyrene are indeed effective in making sustainable hollow blocks that could highly benefit the one’s who are in a tight budget. Additionally, the results reflect that the more concentrated the mixture having greater amount of manure present with the presence of polystyrene (which is a good insulator), the quality is more highly commendable. Given these findings, the researchers recommend that there should be a deep concern regarding this study since it has the bigger potential to be marketed offering an productive quality at an affordable cost which is more cheaper than the hollow blocks available to the market.

Purpose: Research interest in Internet of things (IOT) and autism spectrum disorder (ASD) has grown. In this literature, we will discuss how computer technologies can recover the life value of the people with the Autism. There is a requirement to analyze the literature to let computer technologies reflect their applicability. The literature target was to study nature and results of studies probing IOT valuation in ASD. Technique: A systematic examination of the different literature was carried out, in which 7 studies are matched with an inclusion criteria. Information was taken out by authors from every involved article, containing characteristics of the participant, use of technology, actions and reported results. Superiority literature of all the articles was carried out. Result: The 284 participants with autism spectrum disorder across the 7 involved studies include the participant with the age from 6 months to middle age. The quality of the studies varied. A variety of services were delivered via IOT, including diagnostic assessment and early detection. Results suggested that services delivered through various internets of things were equal to services provided face to face, and higher to human techniques. Conclusion: The suggested outcomes might be a sequence of benefits with the use of internet of things with individuals suffering from ASD, their families, and trainers. Additional research is essential mainly regarding the usage of IOT openly with kids with ASD for the assessment and involvement

Software engineering is an important area that deals with development and maintenance of software. After developing a software, it is always important to track its performance. One has to always see whether the software functions according to customer requirements. To ensure this, faulty and non- faulty modules must be identified. For this purpose, one can make use of a model for binary class classification of faults. Different technique's outputs differ in one or the other way with respect to the following: fault dataset used, complexity, classification algorithm implemented, etc. Various machine learning techniques can be used for this purpose. But this paper deals with the best classification algorithms available till date and they are decision tree, random forest, naive bayes and logistic regression (tree-based techniques and bayesian based techniques). The motive behind developing such a project is to identify the faulty modules within a software before the actual software testing takes place. As a result, the time consumed by testers or the workload of the testers can be reduced to an extent. This work is very well useful to those working in software industry and also to those people carrying out research in software engineering where the lifecycle of development of a software is discussed.
Bènaco o Benaco?
Authors: Caffarelli Enzo
Published: April 2020

Una lettrice ci scrive a proposito dell’accento da porsi su
Benaco, altro nome del lago di Garda: dice che sente
spesso pronunciarlo con l'accento sulla seconda vocale,
mentre a sua detta i veronesi abitanti del lago mettono
l'accento sulla prima vocale.

Bei tempi quando a Milano si andava all’Expo in metrò!
Authors: D'Achille Paolo
Published: April 2020

In questi giorni in cui tutti, nell’attesa che cessi l’emergenza COVID-19, dobbiamo restare in casa, evitando contatti con altre persone, e in cui sono vietati convegni, assembramenti e manifestazioni, riprendiamo alcuni quesiti che erano rimasti senza risposta, relativi alle parole expo e metro/métro/metrò. In tal modo, ricordando l’evento che si svolse a Milano con successo nel 2015 e l’affollata ma efficientissima rete di trasporti del capoluogo lombardo, con cui, tra l’altro, si poteva raggiungere comodamente la sede di Rho-Fieramilano, intendiamo fare un omaggio beneagurante a questa città, particolarmente colpita, insieme alla sua regione, dagli effetti del coronavirus (e quindi, implicitamente, all’intero Paese).
ОПИСАНИЕ СЛОВООБРАЗОВАТЕЛЬНЫХ ПАРАДИГМ, ФОРМИРУЮЩИХ СЛОВООБРАЗОВАТЕЛЬНОЕ ГНЕЗДО С ВЕРШИНОЙ «ВЕРА»
Authors: KHASANOV Eldar
Published: April 2020

Статья посвящена детальному описанию словообразовательных парадигм, формирующих словообразовательное гнездо с вершиной вера, в формально-семантическом аспекте. Особое внимание уделено глаголам, присутствующим на разных ступенях словообразования данного гнезда. Автор придерживается теории, что словообразовательная парадигма является комплексной единицей, образовавшейся в результате исследования радиальных отношений между производящей основой и производными. В результате проведенного исследования удалось выяснить, что компоненты словообразовательной парадигмы характеризуются семантической независимостью друг от друга и связываются между собой по смыслу лишь посредством семантики производящего. Это и является одним из главных отличий компонентов словообразовательной парадигмы от словообразовательных цепочек и словообразовательных пар, характерной особенностью которых считается отношения включения или отношения зависимости, то есть значение производящего обязательно включается в семантику производного.
Статья будет интересна для широкого круга исследователей, занимающихся вопросами словообразования, а описанные нами данные могут быть использованы при подготовке учебно-методических пособий по лексике и словообразованию русского языка.
Ключевые слова: словообразовательное гнездо; словообразовательная парадигма; дериваты; словообразовательная ступень.
