Framework Two-Tier Feature Selection on the Intelligence System Model for Detecting Coronary Heart Disease

Coronary heart disease is a non-communicable disease with high mortality. A good action to anticipate this is to do prevention, namely by carrying out a healthy lifestyle and routine early examinations. Early detection of coronary heart disease requires a number of examinations, such as demographics, ECG, laboratory, symptoms, and even angiography. The number of inspection parameters in the context of early detection will have an impact on the time and costs that must be incurred. Selection of the right and important inspection parameters will save time and costs. This study proposes an intelligence system model for the detection of coronary heart disease by using a minimal examination attribute, with performance in the good category. This research method is divided into a number of stages, namely data normalization, feature selection, classification, and performance analysis. Feature selection uses a Two-tier feature selection framework consisting of correlation-based filters and wrappers. The system model is tested using a number of datasets, and classification algorithms. The test results show that the proposed two-tier feature selection framework is able to reduce the highest attribute of 73.51% in the z-Alizadeh Sani dataset. The performance of the system using the bagging-PART algorithm is able to provide the best performance with parameters area under the curve (AUC) 95.4%, sensitivity 95.9% while accuracy is 94.1%. Referring to the AUC value, the proposed system model is included in the good category.
Biological Desulfurization of Tannery Effluent Using Hybrid Linear Flow Channel Reactors

The tanning process generates a saline effluent with high residual organics, sulfate and sulfide concentrations. The transition from a linear to circular economy requires reimagining of waste streams as potential resources. The organics in tannery effluent have the potential to be converted to renewable energy in the form of biogas if inhibitors to anaerobic digestion are removed. Hybrid linear flow channel reactors inoculated with culture-enriched halophilic sulfate reducing bacteria from saline environments were evaluated as a novel pretreatment step prior to anaerobic digestion for the concurrent removal of sulfur species and resource recovery (elemental sulfur and biogas). During continuous operation of a 4-day hydraulic retention time, the reactors were capable of near-complete sulfide oxidation (>97%) and a sulfate reduction efficiency of 60–80% with the formation of a floating sulfur biofilm containing elemental sulfur. Batch anaerobic digestion tests showed no activity on untreated tannery effluent, while the pretreated effluent yielded 130 mL methane per gram COD consumed.
Using GPS to Measure Traffic System Performance

Traffic system performance can be measured in various ways, but from the user perspective, congestion is the major criterion. This article examines some novel uses of GPS in the measurement of vehicle speeds and travel times and their synthesis into measures of congestion and ultimately of the performance of the urban road system. The article also will discuss the integration of GPS‐based congestion measures into an ITS framework, techniques for implementing a congestion‐monitoring system, and implications for urban road system planners, managers, and users.
Prediction of Soc in Calcic Chernozem in the Steppe Zone of Ukraine Using Brightness and Colour Indicators

Abstract Soil organic carbon (SOC) is an important component of any soil which determines many of its properties. Nowadays, more and more attention is being paid to the SOC content determination in soils by not using the conventional, time-consuming and expensive technique, but by using colour image processing of soil samples. In this case, even the camera of modern smartphones can be used as an image source, making this technique very convenient and practical. However, it is important to maintain certain standardised conditions (light intensity, light incidence angle, etc.) when capturing the images of soil samples. In our opinion, it is best to use a regular scanner for this purpose, with subsequent image processing by graphic programs (e.g., Adobe Photoshop). To increase the reliability of the colour information obtained in this way, it is desired (if possible) to use a spectrograph or a monochromator in the subsequent calculation of reflection or brightness ratios. It is these two approaches that we have implemented in our work. As a result of the experiment, the values of brightness ratios (at 480, 650 and 750 nm wavelengths and integral brightness ratio), colour indicators (the hue, saturation and value [HSV], red, green and blue [RGB], CIE L*a*b* and cyan, magenta, yellow and key [CMYK] systems) and SOC content in Calcic Chernozem samples of the steppe zone of Ukraine were obtained. Using correlation analysis of the dataset, the existence of direct (r = 0.88–0.90) and inverse close relationships (r = −0.75–0.90) between SOC, values of brightness ratios and colour indicators of the soil samples were established. This allows us to develop predictive models. Statistical analysis showed that the models were significant when they were based on the values of brightness ratios at 650 nm wavelength, integral brightness ratio, V indicator in HSV system, R, G and B indicators in RGB system, C, M and K indicators in CMYK system and L* and b* indicators in L*a*b* system. The subsequent calculation of variation coefficients showed that the largest variability was observed in SOC indicators (CV = 0.72) and slightly less variability in the K index of CMYK system and brightness ratio values at 650 nm wavelength (CV = 0.67 and 0.53, respectively). Based on this, we believe that the models y = 0.0188 + 0.0535*x (x is the value of the K index in CMYK system) and y = 5.0716 – 3.2255*log10(x) (x is the value of brightness ratio at 650 nm wavelength) were the most statistically significant and promising parameters for determining SOC content (y in these equations) in Calcic Chernozem samples of the steppe zone of Ukraine.
The transition region between bound-wave and leaky-wave ranges for a partially dielectric-loaded open guiding structure

Most modes on partially dielectric-loaded open guiding structures are purely bound in some frequency range and leaky in another. The transition region between them is complicated and interesting, including a section where the dispersion curve doubles back because it connects a complex nonspectral (leaky-wave) solution with a real spectral (bound-wave or surface-wave) solution. The physical nature of this type of transition region is discussed qualitatively, where some anomalous features are considered; then numerical values for a specific example, a recently proposed novel leaky-wave antenna structure, are presented. >
Quality New Development in English Market Towns: Case Studies Examining the Role of Town Planning

The role of town planning (development control in particular) in urban design issues relating to new development is poorly understood and undervalued. The aim of this study was to investigate to what extent the planning process made a difference to outcomes, and what factors relating process and use of policy were more likely to lead to positive outcomes. Views of key players in the statutory planning decision-making process, in four case-study towns, were obtained through semi-structured interviews. The case-study towns included Ludlow, Dorchester, Chichester and Durham. An example of a ‘successful’ and an ‘unsuccessful’ major new development was examined for each town. The findings indicate that planning can play a significant role in securing a successful outcome, but organizational and political issues, as well as varying skill levels, can hinder the role and give rise to negative perceptions. It is clear that many factors have to work together to help ensure good outcomes, and there is no quick fix. Opportunities for improvement in the design input by planning, including local development frameworks, are considered.
Desalination and Detoxification of Textile Wastewater by Novel Photocatalytic Electrolysis Membrane Reactor for Ecosafe Hydroponic Farming

In this study, a novel photoelectrocatalytic membrane (PECM) reactor was tested as an option for the desalination, disinfection, and detoxification of biologically treated textile wastewater (BTTWW), with the aim to reuse it in hydroponic farming. The anionic ion exchange (IEX) process was used before PECM treatment to remove toxic residual dyes. The toxicity evaluation for every effluent was carried out using the Vibrio fischeri, Microtox® test protocol. The disinfection effect of the PECM reactor was studied against E. coli. After PECM treatment, the 78.7% toxicity level of the BTTWW was reduced to 14.6%. However, photocatalytic desalination during treatment was found to be slow (2.5 mg L−1 min−1 at 1 V potential). The reactor demonstrated approximately 52% COD and 63% TOC removal efficiency. The effects of wastewater reuse on hydroponic production were comparatively investigated by following the growth of the lettuce plant. A detrimental effect was observed on the lettuce plant by the reuse of BTTWW, while no negative impact was reported using the PECM treated textile wastewater. In addition, all macro/micronutrient elements in the PECM treated textile wastewater were recovered by hydroponic farming, and the PECM treatment may be an eco-safe wastewater reuse method for crop irrigation.
Investigation of the Variability of Alkaloids in Buxus sempervirens L. Using Multivariate Data Analysis of LC/MS Profiles

Buxus sempervirens L. is a common ornamental plant in southern and central Europe, and has been used ethopharmacologically against a wide variety of diseases due to it containing nor-triterpene alkaloids of the nor-cycloartane type. Recently, we demonstrated the interesting antiprotozoal potential of some of these compounds. To characterize the temporal variability in the alkaloid profile of two different varieties and their leaves and twigs, 30 different extracts of B. sempervirens were evaluated by Ultra High Performance Liquid Chromatography/positive Mode-Electrospray Ionization Quadrupole Time-of-Flight-Tandem Mass Spectrometry (UHPLC/+ESI-QqTOF-MS/MS). The analytical profiles were thoroughly investigated by various methods of multivariate data analysis (MVDA). A principal component analysis (PCA) model elucidates the seasonal variation in the phytochemical composition of B. sempervirens var. arborescens and suffruticosa along with differences between the varieties. Analysis of a volcano plot illustrated the differences between the two organs, the leaf and twig. Eighteen compounds were highlighted by the models as constituents of the plant characteristic for a season, variety or organ. These compounds were dereplicated based on their chromatographic and +ESI-QqTOF-MS and –MS/MS data. In addition, mass spectral fragmentation pathways for already known alkaloids as well as new natural products could be postulated for the first time. In conclusion, the MVDA models give detailed information on the temporal variability in the alkaloid profile of two different varieties and their organs (leaf vs. twig) of B. sempervirens. Thus, the results of this study allow, e.g., the identification of characteristic compounds for the different varieties, plant organs, seasons, and the optimal harvesting time for the isolation of particular Buxus-alkaloids of interest for subsequent studies.
Radon measurements in the cave houses of Crevillente (Spain)

This paper focuses on the cave houses of Crevillente (Spain) as a traditional housing experience which takes advantage of local environmental conditions through simple architectural proposals, paying particular attention to the presence of radon gas inside these underground constructions. Our aim is twofold: first, to analyse the architectural conditions of the different excavated typologies found in the municipality and second, to relate them to the existing radon gas levels after checking internal concentration by means of E-PERM® long-term devices placed inside the cave houses in 2011. The measurements corresponding to the main typologies in normal use conditions show that the highest values are 881.9 Bq/m3 in the cave typology, 484.1 Bq/m3 in the cave + attached constructions typology and 373.4 Bq/m3 in the cave + house typology, with geometric mean values of 572.1, 114.0 and 75.5 Bq/m3, respectively. It can be inferred from these results that cave house levels sometimes exceed those included in the 90/143/Euratom European Commission Recommendation on the protection of the public against indoor exposure to radon. The reason why cave houses are more susceptible to radon accumulation in their spaces lies in their direct and permanent contact with the ground where they are located.
Acquired mild cognitive impairment in adults with Down syndrome: Age‐related prevalence derived from single point assessment data normed by degree of intellectual disability

Individuals with Down syndrome (DS) are at significant risk for early onset Alzheimer's disease (AD), likely due to the triplication of genes on chromosome 21 that facilitate AD neuropathology. To aid the effective early diagnosis of dementia in DS, we demonstrate the strategy of using single point assessment of cognitive performance with scoring normed for degree of intellectual disability to generate age related prevalence data for acquired mild cognitive impairment (AMCI).
A Reconstruction of Wetland Information in Pre-Settlement Southern Manitoba Using a Geographic Information System

Original Dominion Land Survey (DLS) township maps from the 19th century provide information to characterize pre-settlement surface conditions in the Canadian Prairies. Surveyors produced maps and detailed notes of landscape features such as wetlands, prairie, woodlands, water bodies and the locations of springs. Using these maps, stored in the Provincial Archives of Manitoba (PAM), historic wetlands and vegetation cover for a portion of the Red River basin in southern Manitoba were reconstructed and mapped with a Geographic Information System (GIS). To date, 100 townships, covering approximately 9,400 km2 have been captured in the GIS and analyzed into the categories of wetland, prairie, woodland, scrub and water. Wetlands represented 1,098 km2; prairie approximately 6,800 km2; woodland just over 1,000 km2; scrub about 500 km2; and water 3.2 km2. Applying these categories, a preliminary map of the pre-settlement landscape has been generated. The use of environmental reconstruction techniques, including written or graphic documentary evidence provides baseline information to improve understanding of environmental changes and causes of these changes.
An Internet of Things Based Intercity Bus Management System for Smart City

: In Indonesia, the bus management system is still manually conducted. The integration of ticketing, tracking, monitoring, and reporting is challenging since it is done manually by different people without a standardized operational standard implementation, depends on the person. To improve the efficiency of the intercity bus management system, the internet of things (IoT) is implemented for ticketing, tracking, monitoring, and reporting system. The ticketing system uses QR codes to store passenger identity and booking data; thus, there is no need for paper-based tickets. Global Positioning System (GPS) tracker embedded in each bus is used to track and monitor bus location and condition. Devices will be connected to the internet, such that all data could be store in the cloud server and processed before displayed via a web-based application. A potential passenger could see the bus schedule and order a ticket via this website. The current passenger could monitor bus location such that they do not need to wait for a long time at the bus stop and ensure their seating on the bus. QR scanner is built in the bus to confirm passenger identity and seating number. Bus company only need to gather all data in the cloud to make a report on bus operations.
Effect of Water Immersion on Raw and Expanded Ugandan Vermiculite

Effect of water immersion at different times (from 1/2h to 24 h) on raw and expanded vermiculite from Uganda was investigated. The expansion was carried out by electrical heating at different temperatures and by irradiation with microwaves. After, the expansibility (k) and the water absorption content (WA) were obtained and the samples were characterized. The elemental and mineral composition was determined by X-ray fluorescence and X-ray diffraction, respectively; the thermal behavior by thermal gravimetric analyses; and the textural parameters by BET. The expansibility of Ugandan vermiculite is relatively lower than the other commercial vermiculites due basically to its lower K2O content (0.36%) and higher water content (about 20%). The water absorption capacity of samples significantly increased with the increase in heating temperature. The maximum WA content, about 130 mg/g, was obtained at 900 °C for 24 h. The loss of water during the expansion process in the Ugandan vermiculite caused loss of structural order and crystallinity. Moreover, in the samples expanded and subsequently immersed in water, the structural order and crystallinity increased with increasing WA values. Specific surface area and porosity hardly vary with temperature and are practically independent of vermiculite purity. Expanded commercial vermiculites could be a suitable hygroscopic material, given its efficient water absorption. Microwave expanded commercial vermiculites, in this case, would not be recommended
In-Plane Strain Measurement in Composite Structures with Fiber Bragg Grating Written in Side-Hole Elliptical Core Optical Fiber

In this paper, the application of a fiber Bragg grating written in a highly birefringent side-hole elliptical core optical fiber for two-axial strain measurement is presented. Hybrid optical fiber structures achieved by combining large side-holes and elliptical core result in a very high birefringence of 1 × 10−3 and thus high initial Bragg peak spectral separation of 1.16 nm, as well as a very high transverse force sensitivity, of up to 650 pm/(N/mm) or even −1150 pm/(N/mm), depending on the fiber orientation with respect to the applied force. Due to the ~22 %m/m GeO2 concentration in the core the fiber being highly photosensitive, which significantly simplifies FBG fabrication by UV illumination without the need for prior hydrogen loading, which worsens thermal stability. Finally, the developed FBGs written in the highly birefringent side-hole elliptical core optical fiber were embedded in the square composite plates and applied for strain measurements. Tests of two-directional four-point bending have shown usability of such FBG for two-axial in-plane strain measurement with a single FBG in iso-thermal conditions.
Potential health benefits and food applications of rice bran protein: research advances and challenges

ABSTRACT The climate changes, soil fertility decline, water scarcity, and desertification are expected to generate a great threat to crop production and food security worldwide. Additionally, more food is needed to meet the demand of the world’s growing population. Therefore, scientists are searching for innovative strategies to reduce food loss and enhance food security. Utilization of food processing by-products as food or food ingredients is one of the proposed strategies that can contribute to food security. Rice is a major food crop worldwide and there is a great amount of rice bran is produced as a byproduct of rice milling. Bran constitutes about 10% of the rough rice grain and it is rich in nutrients and bioactive compounds. Rice bran protein (RBP) has shown good nutritional and biological values. Therefore, many studies have been carried out to investigate the suitability of RBP for the application in preparing nutritional and healthy foods. Also, hydrolysates and peptides with various biological activities were isolated from RBP and identified. Therefore, this article aimed to review the research advances in extraction, potential health benefits, and food applications of RBP and its derived hydrolysates. Challenges facing the application of RBP in the food industry are also discussed. GRAPHICAL ABSTRACT

This is supposed to help managers focus their attention on the service quality dimension that matters most to customers.
Propagation Area of Flashover on Solar Array under Electron Environment Simulating Geosynchronous Orbit

Flashover discharge on the solar array is an issue of spacecraft charging, because the discharge potentially causes the catastrophic failure of a satellite. The discharge experiment on solar array has been carried out to investigate the propagation area of flash-over discharge. During the flash-over discharge, neutralization current flows on the solar array strings. The charge of neutralization current was calculated to investigate the relationship between the charge and the distance from the cathode spot. The experiment result in the maximum propagation area of flash-over plasma is 3m in simulated geostationary orbit.
The mechanism of social media marketing: influencer characteristics, consumer empathy, immersion, and sponsorship disclosure

Abstract Recently, influencer marketing and sponsorship activities have been crucial in marketing communication. This paper explores the relationship between influencers’ characteristics (i.e., centrality and trustworthiness), the efficacy of social media posting (i.e., empathy and immersion), and consumers’ product attitude. The study further reveals a critical role of sponsorship disclosure in this mechanism. Based on the data from social media users, our findings demonstrated that influencers’ centrality and trustworthiness were positively related to consumers’ empathic response and immersion toward the social media posting. Consumers’ empathy and immersion strongly mediate the link between influencers’ characteristics and consumers’ attitudes toward the product. Notably, the current study also indicated the moderating role of sponsorship activities and found different effects of centrality and trustworthiness with an apparent sponsorship disclosure. Theoretical and practical implications are further elaborated.
Modeling of Reinforced Concrete Assemblies under Column-Removal Scenario

AbstractThis paper presents a computational investigation of two reinforced concrete beam-column assemblies, each comprising three columns and two beams, subjected to monotonically increasing vertical displacement of the unsupported center column simulating a column removal scenario. One assembly was part of an intermediate moment frame and the other was part of a special moment frame. Two types of models were developed: (1) detailed models with highly refined solid and beam elements to represent the nonlinear material behavior of concrete and reinforcement, and (2) reduced-order models with significantly fewer beam and spring elements to represent the nonlinear behavior of structural components. Reduced models are desirable for analysis of complete three-dimensional (3D) structural systems. Modeling approaches for the detailed and reduced models are described, and the computational results are compared with experimental data from full-scale tests. Good agreement is observed, which demonstrates the capabi.
