Lightweight pyramid residual features with attention for person re-identification
Authors: Rachmadi Reza Fuad , Purnama I Ketut Eddy , Nugroho Supeno Mardi Susiki
Published: April 2023

Person re-identification is one of the problems in the computer vision field that aims to retrieve similar human images in some image collections (or galleries). It is very useful for people searching or tracking in a closed environment (like a mall or building). One of the highlighted things on person re-identification problems is that the model is usually designed only for performance instead of performance and computing power consideration, which is applicable for devices with limited computing power. In this paper, we proposed a lightweight residual network with pyramid attention for person re-identification problems. The lightweight residual network adopted from the residual network (ResNet) model used for CIFAR dataset experiments consists of not more than two million parameters. An additional pyramid features extraction network and attention module are added to the network to improve the classifier's performance. We use CPFE (Context-aware Pyramid Features Extraction) network that utilizes atrous convolution with different dilation rates to extract the pyramid features. In addition, two different attention networks are used for the classifier: channel-wise and spatial-based attention networks. The proposed classifier is tested using widely use Market-1501 and DukeMTMC-reID person re-identification datasets. Experiments on Market-1501 and DukeMTMC-reID datasets show that our proposed classifier can perform well and outperform the classifier without CPFE and attention networks. Further investigation and ablation study shows that our proposed classifier has higher information density compared with other person re-identification methods.
Municipal Solid Waste as a Long-Term Source for Generating Energy
Authors: ABHISHEK GUPTA
Published: April 2023

This article provides a summary of the strategies currently in use to extract energy from municipal solid waste. Special trash is ignored since its characteristics greatly vary from type to type and from region to region. However, municipal solid waste has properties that make it amenable to a more standardized investigation of its energy potential. The initial part examines the methods for extracting usable energy from garbage. The second part discusses energy availability in the context of the changing qualitative and quantitative characteristics of Municipal Solid Waste (MSW). The third section takes a look at selective collection and how it serves the larger goal of energy recovery. In the fourth part, the significance of Directive 1999/31/CE and its effect on energy recovery strategies are discussed in the context of the current trend in the use of residual municipal solid waste. A mandatory pre-treatment makes less interesting the option of landfilling, moving the energy exploitation of residual municipal solid waste towards thermal treatments. Also, research shows how thermal treatments and anaerobic digestion could work together to provide for a local resident's energy needs.
Fresh Ideas: Side by Side Summer Research Program Conference 2021
Authors: Linga-Easwaran Janaksha , Zhang Ashley , Dib Vanessa
Published: April 2023

Side by Side Agency (SBS) is a student-led educational non-profit based in the Greater Toronto Area. We began by providing free virtual tutoring and mentorship for K-12 students to compensate for pandemic-related educational disruptions. When school services returned, we switched gears to focus on persisting barriers to academia for marginalized students primarily addressing inconsistencies in research education across Ontario. Literature on Canadian undergraduate students’ literacy and research skills affirmed our personal difficulties with entering the research field, motivating us to develop a free, accessible, and supportive beginner research program for high school students. The 2021 SBS Summer Research Program (SBS SRP) was developed by undergraduate volunteers and included weekly lessons, workshops, homework, and guest speakers to cultivate research skills and inspire curiosity. Students worked with undergraduate mentors to pursue research projects of their interest in fields such as neuroscience, public health, and sociology. SBS SRP culminated with our conference, where students presented their literature reviews, proposed studies, and informative social media campaigns.

Design and Synthesis of 3D Covalent Organic Frameworks
Authors:   , Fernandez Irene Marice
Published: April 2023

The results of the COP26 summit showed an increased commitment both from politicians and businessmen to phase out the production of internal combustion engines within the next two decades. Within this period, there is a need to provide solutions to the technological gaps to help lower the operational and manufacturing costs of zero emission vehicles and improve their marketability. Fuel cell vehicles have the greatest potential as the sustainable alternative for light and heavy vehicles. In line with this, this project aims to improve the hydrogen storage capacity of the tanks by using adsorbents made from stable, lightweight porous materials with high surface areas, by designing and synthesizing highly crystalline imine-based 3D covalent organic frameworks (COFs) that can meet the operational targets set by the US DOE. The design of the proposed 3D COF was inspired by the non-interpenetrated acs topology of the MOF NU-1501-Al which currently boasts the highest %H2 deliverable capacity. Computational simulations showed that the COF design can surpass its MOF counterpart. To achieve the desired COF, the key monomer with a trigonal prismatic geometry must be synthesized first. Of the two monomers, only the formyl bearing monomer TIAM was successfully synthesized and characterized by MS, NMR and single crystal data. However, attempts to form the target 3D COFs both failed due to lack of reaction time and heating, as evidenced from the FTIR and PXRD data. While the amine-bearing monomer was not synthesized, the key intermediate - the boronate ester of the aryl bearing the Boc-protected amine groups - was successfully synthesized; thus, it is a step closer to the synthesis of the amine-bearing monomer. While the attempts to synthesize a 3D COF failed, the successful synthesis of TIAM adds an additional type of monomer to the limited pool of available monomers for 3D COFs.

Published: April 2023

Background & Objective: Office hysteroscopy (OH) is an efficient alternative for diagnosis and management of intrauterine pathology. The main goal of this study is to determine the usefulness and tolerability of OH in the patient population of a tertiary teaching hospital in the Kingdom of Bahrain. Methods: The total population consists of 101 patients who were prospectively included in the study from 2018 to 2020. The main indication for OH were abnormal uterine bleeding followed by post-menopausal bleeding. Results: The procedure was tolerable without analgesia in 93% of cases, analgesia was required in 3.96% of cases, and minor complications consisted of abdominal pain and dizziness (0.99%), as well as uterine bleeding (0.99 %). Given a success rate of 90% using a 1.8mm diameter hysteroscope, it can be concluded that OH with Etonox (N2O2) as an analgesic is a safe and feasible procedure for patients of varying ages and parities. Conclusion: OH is particularly useful in the workup of abnormal uterine bleeding, post-menopausal bleeding, assisted IUCD removal, endometrial biopsy, and the removal of small polyps.

Authors: Parastou Rahimi , Archchana Rajmohan , Atif Mian Muhammad
Published: April 2023

Background and objectives: Cataract is common in aging populations, and causes blurry vision. Once it interferes with daily activity, it is treated surgically and may lead to complications such as posterior capsule rupture (PCR). The present study aims to calculate the rate of PCR and determine its correlation with age and hypertension. Methods: This retrospective study was conducted between 31st August, 2016 to 30th December, 2018 at the Department of Ophthalmology, King Hamad University Hospital (KHUH), Bahrain. A total of 458 Bahraini patients, including 199 (43.5%) women and 259 (56.5%) men with a mean age of 66.2 ± 9.186 years (S.D.), were studied. Data from medical records and the theater logbook depicted two types of procedures, phacoemulsification and extracapsular-cataract-extraction (ECCE), which were performed by a single surgeon. Data were analyzed using SPSS (Version 26.0). Results: Of the 458 patients studied, 7 patients (1.5%) developed complications. Out of these patients who developed complications, 4 (0.8%) cases were of PCR with no vitreous loss. On analysis, age was a significant risk factor for patients above 60 years (P=0.05), whereas hypertension was not a significant (P=0.760) risk factor for developing PCR as a complication. Conclusion: Low PCR rates were reported in this study. Contributing factors to this low occurrence of PCR could be the identification of high-risk patients and years of the surgeon’s experience. The study highlights that patients above 60 years were at higher risk of developing PCR complications. In contrast, patients with hypertension were at lesser risk of developing PCR complications. Keywords: Cataract, extracapsular cataract extraction, hypertension, phacoemulsification, posterior capsule rupture, vitreous loss, zonular dialysis.

The modern financial market is in dire need of comprehensive and effective information support. This need is based on the fact that absolutely all processes (from the formation and processing of information to the construction of forecasts and models for the purpose of making managerial decisions) require large-scale calculations and a long time, which is excluded with the use of information technology. The modern process of formation and integrated functioning of the latest information technologies is closely related to the activities of financial markets and sets the most important task of automating the processes of this sector of the economy. This article describes the importance of modern information technologies, both for the financial market of a particular region and within the country as a whole, their features and factors affecting the promotion process are identified. Automated information technologies are considered by the authors as a cost-saving tool for modern enterprises, which are closely related and implemented in all spheres and directions of society’s life and in all economic and social processes. Special attention is paid to the disclosure of the features of the use of information technologies in the financial sector. At the same time, the prospects of using such new technologies as artificial intelligence, blockchain, etc. are shown.

The article presents the results of a study on the organizational and methodological aspects of assessing the quality of accounting information in the activities of business entities in the service sector. Within the framework of the scientific article, the author’s view on the assessment of the quality of accounting information is presented based on the indicators of the accounting (financial) statements of business entities in the service sector. The study proposes the use of process methodological support for assessing the quality of reporting of business entities in the service sector. The study concludes that the quality of accounting information is expressed not only by the correct implementation of all the norms in the field of accounting and reporting, but also as a result of the process of regulation and standardization of the entire accounting process, including the organization of managerial decision-making by an economic entity in the sphere services with the obligatory presence of an effective control system, both the quality of accounting and the quality of managerial decision-making.
Distance spectral radius and Hamiltonicity of a graph
Authors: Benediktovich V. I.
Published: April 2023

In recent years, the eigenvalues of the distance matrix of a graph have attracted a lot of attention of mathematicians, since there is a close connection between its spectrum and the structural properties of the graph. Thus, quite recently an interesting result was obtained, relating the Hamiltonicity of a graph to the distance spectral radius of the graph, on the basis of which a more general conjecture about the Hamiltonicity of a graph was formulated. We confirm this conjecture put forward for a k-connected graph, when k Î{2;3}, and also establish similar sufficient conditions for the traceability of a k-connected graph, when k Î{1; 2}.

Elimination of defects in a welded joint in a niobium superconducting resonator
Authors: Burin A. A. , Zaleski V. G. , Pobol I. L.
Published: April 2023

The possible reasons for the appearance of defects during welding of a niobium superconducting coaxial halfwave resonator (HWR) are investigated, which consist in the deviation of the shape of the welded surface from the given one, in the deviation of the angle of incidence of the beam from the perpendicular to the welded surface, in fluctuations in the thickness of the welded edges, and also the presence of some instability (pulsation) accelerating voltage, beam currents and focusing of the electron beam gun. The possibilities of preventing the appearance of defects during welding are determined, which consist in regulating the operating parameters of the electron beam gun depending on possible errors in the manufacture and preparation of the welded edges. Methods for elimination of defects in welding of niobium superconducting coaxial HWR are studied. A method has been developed for repairing defects in welded joints such as burn-throughs on the type of resonator under study using electron-beam deposition. The results of measuring the resonant frequency of the HWR before the onset and after the recovery of burn-through are presented, which showed that the melting of the hole did not lead to a change in the electrical characteristics. Vacuum and cryogenic tests at liquid nitrogen temperature confirmed the tightness of the welded joints. The results obtained can be used in the development of basic technologies for the restoration and repair of expensive and difficult-to-manufacture elements of accelerator technology – superconducting high-frequency resonators made of high-purity niobium sheet.

Published: April 2023

The results of the study of drying thin natural leather pasted on a smooth surface are presented. The results of solving the differential equation of non-stationary heat conduction with constant thermophysical coefficients are used to determine the average temperature during the period of decreasing drying rate. The calculated values of temperatures for moisture-proof and moisture-free skin surfaces are given. Methods for simplifying solutions of nonlinear equations with the aim of linearizing these equations for approximating solutions with variable transport coefficients are considered. The use of the method of piecewise stepwise approximation of the transfer coefficients with constant values of these coefficients over short time intervals showed that for low-intensity drying processes, the solutions of the linear heat equation are implemented quite accurately, confirming the regularities obtained empirically. The calculation of the duration of drying according to the method of B. S. Sazhin is given. The results of the processing of experimental curves for drying leathers pasted are presented. The reliability of the obtained equations is verified and the experiment is compared with the calculated values using the formulas. The obtained approximate analytical solutions with reliable values of the transfer coefficients, confirmed by experimentally established regularities, are of practical importance. Together with experimental methods, analytical methods make it possible to establish optimal drying regimes and more accurately generalize experimental data.
Heat and mass transfer of drops of concentrated solutions during spray dehydration under conditions of convective-radiation energy supply

Published: April 2023

The results of modeling the dehydration of drops of a concentrated liquid, on the example of ceramics, with convective-radiation energy supply under conditions of direct-flow and counter-current phase motion, as well as pulsed counter-flows of gas, are presented. A model for the dehydration of a single drop is formulated based on the equations of heat conduction with a source term and diffusion of moisture, taking into account the change in its size due to evaporation. This takes 

into account the influence of the convective vapor flow from the evaporating droplet surface (Stefan flow), as well as the blowing of evaporating vapor into the hot gas flow on the heat transfer coefficient (Spalding correction). The impact of infrared radiation is described by the Bouguer equation. The equation of motion of a drop in a gas flow takes into account the forces due to gravity, the difference in velocities and phase densities. As a result of numerical simulation, it was found that with countercurrent phase movement, the intensity of dehydration is higher than with cocurrent flow. This is due to both an increase in the relative velocity of the phases and an increase in the residence time of the drop in the intense region of infrared radiation. It is shown that further intensification of evaporation is possible due to the creation of pulsed counter gas flows. The calculated results are compared with the experimental data, which confirms the adequacy of the model. The results of the study can be useful in the development of new heat technologies and devices for dehydration of concentrated solutions and suspensions.
