Innovative approache for the nonlinear atangana conformable Klein-Gordon equation unveiling traveling wave patterns

The aim of current work is to establish novel traveling wave solutions of the nonlinear Atangana conformable Klein - Gordon equation using a new extended direct algebraic technique. The Klein - Gordon equation is the relativistic state of the Schrödinger equation with a second - order time derivative and zero spin. Complex wave variable transformation is used to convert Atangana conformable nonlinear differential equation into an ordinary differential equation. Using the proposed technique based on Maple software structure, various types of solutions, such as, generalized trigonometric, generalized hyperbolic, and exponential functions, are established. When special parameteric values are considered for this method, solitary wave solutions can be obtained through other methods, such as the (G′G)-expansion method, the modified Kudryashov method, the sub-equation method, and so forth. A physical explanation is provided for the solutions under consideration to enhance comprehension of the physical phenomena resulting from the obtained solutions, provided that the physical parameters are set appropriately using 3D, 2D, and contour simulations. The results demonstrated that the new extended direct algebraic method provides a more potent mathematical tool for solving numerous more nonlinear partial differential equations with the aid of symbolic computation.

NATURAL LIGHT INTENSITY AND VISUAL COMFORT THROUGH ADJUSTING THE HEIGHT OF THE CURTAIN OPENING

The type of activity, room area, and light intensity influence the visual comfort level of room users. In educational buildings, visual comfort influences the level of performance during the teaching and learning process of students. Students of the Bachelor of Architecture Study Program, FTSP, Trisakti University, use the Studio on the 6th floor (C.608-609) with 85% curtained glass window walls on the North and West, and 10% uncurtained bouvenlight windows on the South. It is estimated that the availability of natural light sources with such capacity is sufficient for the Studio learning process, but in fact users still turn on artificial lighting when working during the day. The hope is that by using curtained windows, students can regulate natural lighting needs to reduce the use of artificial lighting. Until this research was conducted, it was not known how high curtains met visual comfort standards. This research aims to create contour simulation of room’s natural light intensity C.608-609 using dialux kw06-288 software, in relation to adjust of curtains on windows with heights of 30 cm, 60 cm, 90 cm and 120 cm, and their impact on the user's feelings of visual comfort or discomfort. The results show that the distribution of natural light entering the room is not even and varied. According to SNI 03-6575-2001, the light intensity for a studio is 500-750 lux, but the measurement results show that at a curtain opening height of 120 cm, the light reach to the room with the furthest depth of 16.8m is not reached, so to achieve visual comfort the assistance of artificial lighting is needed, especially in the east-south of studio. Meanwhile, the area around the light source causes glare. Keywords: Light Intensity, Visual Comfort, Curtain Opening Height

NATURAL LIGHTING’S CONTOUR, CASE: CLASSROOM-STUDIO, FLOOR 6th BUILDING C, UNIVERSITAS TRISAKTI

The room requires specific lighting according to its function. One way to achieve the room's optimal comfort is to adjust the natural or artificial lighting to the required standards. This research aims to study daylight intensity in the architectural classroom studio on the sixth floor of Building C Universitas Trisakti and compare it with the illuminance level requirements stipulated in SNI 6197: 2011. This study hypothesizes that the natural intensity of the room, which also functions as an architectural drawing studio, is incompatible with conventional lectures. The measuring instrument was the Lutron LM 8000A Light Lux Meter, while the natural lighting contour simulation used Dialux Evo 9. The results show that the measured natural lighting intensity is unevenly distributed. There are bright zones in the room that exceed the standard value of the illuminance level (> 350-750 lux) and dark zones that are below the standard of illuminance (<350-750 lux), with a distance of 0.5 m - 3m from a row of window openings as a source of lighting.

Kink Soliton Dynamic of the (2+1)-Dimensional Integro-Differential Jaulent–Miodek Equation via a Couple of Integration Techniques

In this article, the aim was to obtain kink soliton solutions of the (2+1)-dimensional integro-differential Jaulent–Miodek equation (IDJME), which is a prominent model related to energy-dependent Schrödinger potential and is used in fluid dynamics, condensed matter physics, optics and many engineering systems. The IDJME is created depending on the parameters and with constant coefficients, and two efficient methods, the generalized Kudryashov and a sub-version of an auxiliary equation method, were applied for the first time. Initially, the traveling wave transform, which comes from Lie symmetry infinitesimals ∂∂x,∂∂y and ∂∂t, was applied, and a nonlinear ordinary differential equation (NODE) form was derived. In order to make physical interpretations, appropriate solution sets and soliton solutions were obtained by performing systematic operations in line with the algorithm of the proposed methods. Then, 3D, 2D and contour simulations were made. Interpretations of different kink soliton solutions were made by obtaining results that are consistent with previous studies in the literature. The obtained results contribute to the studies in this field, though the contribution is small.

A new implementation of a novel analytical method for finding the analytical solutions of the (2+1)-dimensional KP-BBM equation

In this work, we perform a comprehensive analytical study to find the novel exact traveling wave solutions of the (2+1)-dimensional Kadomtsev-Petviashvili-Benjamin-Bona-Mahony (KP-BBM) equation. The recently developed (G′G′+G+A) -expansion technique is a capable method for finding the new exact solutions of assorted nonlinear evolution equations. Some new analytical solutions are obtained by utilizing the aforementioned method. The obtained solutions are expressed as trigonometric functions and exponential functions. The extracted exact wave solutions are advanced and fully unique from the earlier literature Moreover, we have presented the contour simulations, 2D and 3D graphical representations of the solution functions and we have observed that the solutions obtained are periodic and solitary wave solutions. We have shown two soliton wave solutions and two singular periodic wave solutions for the particular values of the parameters graphically. As per our knowledge, we must say that the extracted solutions might be significant and essential for new physical phenomenon.

Infrared spectra of gaseous peroxychloroformyl radical ClC(O)OO: A key intermediate in the conversion of CO to CO2 in the Venus atmosphere

The peroxychloroformyl radical, ClC(O)OO, was proposed to play a critical role in the catalytic conversion of CO to CO2 in the atmosphere of Venus, but direct spectral characterization of this species in the gaseous phase is lacking. Photolysis of a mixture of (ClCO)2 and O2 near 50 Torr with laser light at 248 nm produced absorption bands of CO, CO2, Cl2CO, and transient absorption bands that can be assigned to ClCO, trans-ClC(O)OO, and cis-ClC(O)OO. Bands at 937, 1014, and 1902 cm−1 are assigned to the OCO bending (ν3), overtone of C−Cl stretching (2ν5), and C=O stretching (ν1) modes of trans-ClC(O)OO. According to rotational contour simulations with PGOPHER, two bands ∼ 1883 and ∼ 1928 cm−1 also contribute to the band near 1902 cm−1; they might be assigned to the ν2 + ν8 + ν9 mode of cis-ClC(O)OO and the ν2 + ν4 mode of trans-ClC(O)OO, whereas the band near 937 cm−1 might have contribution from the 2ν6 (overtone of OC=O bending) mode of cis-ClC(O)OO near 928 cm−1. Bands at 964, 1110, and 1837 cm−1 are assigned to the anti-phase C–O and O–O stretching (ν3), O–O stretching (ν2), and C=O stretching (ν1) modes of cis-ClC(O)OO. The band near 1837 cm−1 might have contribution from the 2ν3 mode of trans-ClC(O)OO and cis-ClC(O)OO near 1829 and < 1829 cm−1, respectively. From the temporal evolution of CO and CO2, we confirmed that the addition of O2 to the photolyzed (ClCO)2 system to form ClC(O)OO enhanced the formation of CO2, supporting the proposed catalytic mechanism.

Soliton theory and modulation instability analysis: The Ivancevic option pricing model in economy

In this projected paper, we study on the Ivancevic option pricing model. We apply two important methods, namely, rational sine-Gordon expansion method which is recently developed, and secondly, modified exponential method. Via these methods, we obtain some important properties of Ivancevic option pricing model. We extract many solutions such as complex, periodic, dark bright, mixed dark-bright, singular, travelling and hyperbolic functions. We investigate the option price wave functions of dependent variable, and also, observe the modulation instability analysis in detail. Furthermore, we report the strain conditions for the valid solutions under the family conditions, as well. We simulate the 2D, 3D and counter plots by choosing the suitable values of the parameters involved. Finally, we present the top and low points of pricing in the mentioned intervals via contour simulations.

CRISP: a deep learning architecture for GC × GC-TOFMS contour ROI identification, simulation and analysis in imaging metabolomics.

Two-dimensional gas chromatography–time-of-flight mass spectrometry (GC × GC–TOFMS) provides a large amount of molecular information from biological samples. However, the lack of a comprehensive compound library or customizable bioinformatics tool is currently a challenge in GC × GC–TOFMS data analysis. We present an open-source deep learning (DL) software called contour regions of interest (ROI) identification, simulation and untargeted metabolomics profiler (CRISP). CRISP integrates multiple customizable deep neural network architectures for assisting the semi-automated identification of ROIs, contour synthesis, resolution enhancement and classification of GC × GC–TOFMS-based contour images. The approach includes the novel aggregate feature representative contour (AFRC) construction and stacked ROIs. This generates an unbiased contour image dataset that enhances the contrasting characteristics between different test groups and can be suitable for small sample sizes. The utility of the generative models and the accuracy and efficacy of the platform were demonstrated using a dataset of GC × GC–TOFMS contour images from patients with late-stage diabetic nephropathy and healthy control groups. CRISP successfully constructed AFRC images and identified over five ROIs to create a deepstacked dataset. The high fidelity, 512 × 512-pixels generative model was trained as a generator with a Fréchet inception distance of <47.00. The trained classifier achieved an AUROC of >0.96 and a classification accuracy of >95.00% for datasets with and without column bleed. Overall, CRISP demonstrates good potential as a DL-based approach for the rapid analysis of 4-D GC × GC–TOFMS untargeted metabolite profiles by directly implementing contour images. CRISP is available at https://github.com/vivekmathema/GCxGC-CRISP.

Electromagnetic Characterization of UHF-RFID Fixed Reader in Healthcare Centers Related to the Personal and Labor Health

Hospitals and healthcare centers are experiencing a remarkable implementation of new systems based on wireless communications technologies. Many of these systems provide location services and identification of materials, instrumentation and even patients, which promotes the increase of the quality and the efficiency of healthcare. A tracking system based on short-range radio frequency, UHF-RFID is evaluated. This system helps with location of orthopedic prosthesis according to the criteria and requirements of a specific hospital environment. It is characterized the influence of UHF-RFID system in the electromagnetic environment by measuring the parameters and characteristics of the emission levels. The results of the assessment are represented through 2D contour maps and simulations have been performed by means of an in-house 3D-RL algorithm. The proposed graph aims to provide a methodology of studying the electromagnetic environments and the evaluation of the safety conditions of workers, patients, and people in general. E field exposure levels due to the RFID localization system were analyzed in order to verify regulations concerning the safety of patients and the general public in the labor and healthcare fields. Localized electromagnetic field exposure at levels which may cause electromagnetic hazards in the specific healthcare environment have been found and potentially excessive exposure to EMF emitted by UHF RFID devices may apply to patients or bystanders. In all cases, insufficient electromagnetic immunity of electronic devices (including AIMD and other medical devices) should be considered and the electromagnetic hazards may be limited also by relevant preventive measures, as also shown in this paper, together with the principles of an in-situ evaluation of electromagnetic hazards near the UHF-RFID devices.

n this research paper under consideration is the nonlinear multi-core coupler (coupling with all neighbors) with the parabolic law nonlinearity and optical metamaterials parameters. The integration scheme, namely the New sub-ODE method, is used to extract bright, dark, trigonometric function solutions, Jacobian elliptic function solutions and Weierstrass elliptic function solutions.

Woodchips as sustained-release carbon source to enhance the nitrogen transformation of low C/N wastewater in a baffle subsurface flow constructed wetland

The lack of carbon source in the denitrification process with low C/N wastewater is the main factor limiting the denitrification efficiency in constructed wetlands (CWs). However, the traditional method of adding liquid carbon source is often costly and facing the risk of secondary pollution. This study attempted to solve this problem by adding woodchips sustained-release carbon sources as part of the substrate, together with the dewatered alum sludge as the main wetland substrate to the baffle subsurface flow constructed wetland (BSFCW). The effects of woodchips on denitrification capacity, effluent COD and nitrogen transfer and transformation were studied. Results showed that the removal rates of ammonia nitrogen (NH4+-N), nitrate nitrogen (NO3−-N), total nitrogen (TN) and total phosphorus (TP) were 19.0%–75.3%, 63.6%–96.1%, 61.94%–74.4%, 75.0%–98.8%, respectively, when the C/N ratio varies between 0.93 and 1.87. The two-dimensional contour simulation of pollutants concentration in the system indicated that: i) the release rate of COD by woodchips decreased with the time; ii) woodchips reduced the oxidation reduction potential (ORP) of CW system, creating favorable conditions for the denitrification; iii) the closer the woodchips filling position to the inlet, the higher the denitrification efficiency of the system. The combination of dewatered alum sludge and woodchips substrates realized the simultaneous denitrification and dephosphorization of the BSFCW system. This study is of great significance for the treatment of low C/N wastewater containing considerable even high strength P.
