Due to the uncertainty and volatility of wind speed, its natural output power also exhibits strong volatility. In order to avoid the negative effects of the excessive fluctuation of the output power of wind turbines in the wind farm and the power grid, it is very important to accurately predict and reasonably plan and control the output power of the wind farm. Model predictive control (MPC) is a type of advanced control method that can deal with a multi-input multi-output nonlinear system. Compared to the traditional proportional integral derivative control, MPC is more suitable for the complex wind farm model and exhibits good control performance, and has been gradually applied to control the wind power in wind farms. In this article, we have summarized the application of the MPC technology in the prediction and control of wind power in a wind farm, analyze the application of the MPC technology, including MPC, multi-objective MPC, nonlinear MPC, and distributed MPC, in the wind farm power control with different optimization objectives. In addition, the optimization of the active and reactive power of wind farms has also been discussed in detail. Furthermore, some hot topics in the current research, such as the multi-objective optimization problem of coordinating the maximum power and reducing the fatigue load and power smoothing control problem, have been summarized. Finally, the existing problems of MPC applied to wind power systems have been discussed.

A 65-year-old female with a history of right lung transplantation (LTx) for chronic obstructive pulmonary disease (COPD) 9-years prior complicated by grade 3 bronchiolitis obliterans syndrome (BOS) was admitted to the hospital for chest pain and dyspnea on exertion (DOE). Her bronchoscopy revealed fluffy, endobronchial lesions that were adherent to the right sided anastomosis resulting in mild obstruction of the right mainstem bronchus. Pathology from biopsies of the endobronchial lesions revealed hyphal fungal organisms consistent with Aspergillus species. Following antifungal therapy with voriconazole, her follow up bronchoscopy 37 days post the original bronchoscopy revealed resolution of the endobronchial lesions. The patient’s case is unique in: presentation 9 years post-transplantation, the absence of prior Aspergillus colonization, and the appearance of the endobronchial lesions. Following Ltx, immunosuppression in combination with allograft exposure to the environment increases the risk of opportunistic infections, especially saprophytic infections including Aspergillus.
Understanding Preferences for Lifestyle-Focused Visual Text Messages in Patients With Cardiovascular and Chronic Respiratory Disease: Discrete Choice Experiment
Authors: Choi Michael , Raeside Rebecca , Hyun Karice , Partridge Stephanie R , Thiagalingam Aravinda , Redfern Julie
Published: July 2021

Background

Supporting healthy lifestyle changes is a key aim of cardiovascular and pulmonary rehabilitation programs. SMS text messaging programs have demonstrated effectiveness in cardiovascular disease risk reduction, weight loss, increasing physical activity, and smoking cessation. The optimization of SMS text messaging programs may deliver greater population benefits as mobile phone use becomes ubiquitous. Visual messaging (ie, image-based messages) has the potential to communicate health messages via digital technology and result in enhanced engagement.

Objective

This study aims to determine and understand patient preferences for lifestyle-focused visual text messages that support cardiovascular and pulmonary rehabilitation.

Methods

A discrete choice experiment was conducted in a 4-stage iterative process to elicit patient preferences for visual message features. Attribute and level development yielded 3 attributes (purpose, image type, and web address), and 16 choice sets were subsequently constructed according to a full factorial design. Patients participating in cardiovascular and pulmonary rehabilitation were surveyed (on the web) for their preferences regarding the visual message choice sets. Respondents were asked to choose among 16 pairs of visual messages regarding key lifestyle behaviors, namely, physical activity and nutrition. The data were analyzed using a conditional logit model.

Results

There was a total of 1728 observations from 54 unique respondents. Two factors that were associated with patient preference were gain-framed purpose compared with no purpose (odds ratio [OR] 1.93, 95% CI 1.40-2.65) and real images compared with cartoon images (OR 1.26, 95% CI 1.04-1.54). A loss-framed purpose was less preferred than no purpose (OR 0.55, 95% CI 0.42-0.74). Overall, patients preferred positive images that were colorful and engaged with text that supported the image and had a preference for images of real people rather than cartoons.

Conclusions

A discrete choice experiment is a scientific method for eliciting patient preferences for a visual messaging intervention that is designed to support changes in lifestyle behaviors. SMS text messaging programs that use visual aids may result in greater patient satisfaction by using a gain frame, using real images, and avoiding a loss frame. Further research is needed to explore the feasibility of implementation and the health and behavioral outcomes associated with such visual messaging programs.

Authors: Woulfe Fionn , Fadahunsi Kayode Philip , Smith Simon , Chirambo Griphin Baxter , Larsson Emma , Henn Patrick , Mawkin Mala , O’ Donoghue John
Published: July 2021

Background

In recent years, there has been rapid growth in the availability and use of mobile health (mHealth) apps around the world. A consensus regarding an accepted standard to assess the quality of such apps has yet to be reached. A factor that exacerbates the challenge of mHealth app quality assessment is variations in the interpretation of quality and its subdimensions. Consequently, it has become increasingly difficult for health care professionals worldwide to distinguish apps of high quality from those of lower quality. This exposes both patients and health care professionals to unnecessary risks. Despite progress, limited understanding of the contributions of researchers in low- and middle-income countries (LMICs) exists on this topic. Furthermore, the applicability of quality assessment methodologies in LMIC settings remains relatively unexplored.

Objective

This rapid review aims to identify current methodologies in the literature to assess the quality of mHealth apps, understand what aspects of quality these methodologies address, determine what input has been made by authors from LMICs, and examine the applicability of such methodologies in LMICs.

Methods

This review was registered with PROSPERO (International Prospective Register of Systematic Reviews). A search of PubMed, EMBASE, Web of Science, and Scopus was performed for papers related to mHealth app quality assessment methodologies, which were published in English between 2005 and 2020. By taking a rapid review approach, a thematic and descriptive analysis of the papers was performed.

Results

Electronic database searches identified 841 papers. After the screening process, 52 papers remained for inclusion. Of the 52 papers, 5 (10%) proposed novel methodologies that could be used to evaluate mHealth apps of diverse medical areas of interest, 8 (15%) proposed methodologies that could be used to assess apps concerned with a specific medical focus, and 39 (75%) used methodologies developed by other published authors to evaluate the quality of various groups of mHealth apps. The authors in 6% (3/52) of papers were solely affiliated to institutes in LMICs. A further 15% (8/52) of papers had at least one coauthor affiliated to an institute in an LMIC.

Conclusions

Quality assessment of mHealth apps is complex in nature and at times subjective. Despite growing research on this topic, to date, an all-encompassing appropriate means for evaluating the quality of mHealth apps does not exist. There has been engagement with authors affiliated to institutes across LMICs; however, limited consideration of current generic methodologies for application in LMIC settings has been identified.

The Persistence of the Impact of COVID-19–Related Distress, Mood Inertia, and Loneliness on Mental Health During a Postlockdown Period in Germany: An Ecological Momentary Assessment Study
Authors: Haucke Matthias , Liu Shuyan , Heinzel Stephan
Published: July 2021

Background

The first wave of the COVID-19 pandemic in early 2020 increased mental health problems globally. However, little is known about mental health problems during a low-incidence period of the pandemic without strict public health measures.

Objective

We aim to investigate whether COVID-19–related risk factors for mental health problems persist beyond lockdown measures. We targeted a vulnerable population that is at risk of developing low mental health and assessed their daily dynamics of mood and emotion regulation after a strict lockdown.

Methods

During a postlockdown period in Germany (between August 8, 2020, and November 1, 2020), we conducted an ecological momentary assessment with 131 participants who experienced at least mild COVID-19–related distress and loneliness. To estimate negative mood inertia, we built a lag-1 three-level autoregressive model.

Results

We found that information exposure and active daily COVID-19 cases did not have an impact on negative mood amid a postlockdown period. However, there was a day-to-day carryover effect of negative mood. In addition, worrying about COVID-19, feeling restricted by COVID-19, and feeling lonely increased negative mood.

Conclusions

The mental health of a vulnerable population is still challenged by COVID-19–related stressors after the lifting of a strict lockdown. This study highlights the need to protect mental health during postpandemic periods.

Authors: Mathur Mala , Kerr Bradley R , Babal Jessica C , Eickhoff Jens C , Coller Ryan J , Moreno Megan A
Published: July 2021

Background

Mindfulness practices are associated with improved health and well-being for children. Few studies have assessed parents’ acceptance of learning about mindfulness practices.

Objective

This study aims to assess parents’ beliefs and interest in learning about mindfulness, including from their health care provider, and differences across demographic backgrounds.

Methods

We conducted a national cross-sectional survey of parents with children aged 0-18 years in October 2018. Measures included beliefs and interest in learning about mindfulness. These measures were compared across demographic backgrounds using chi-square analysis. Multivariate linear and logistic regression analyses were used to perform adjusted comparisons between demographic backgrounds.

Results

Participants (N=3000) were 87% (n=2621) female and 82.5% (n=2466) Caucasian. Most (n=1913, 64.2%) reported beliefs that mindfulness can be beneficial when parenting, 56.4% (n=1595) showed interest in learning about mindfulness to help their child stay healthy, and 40.8% (n=1214) reported interest in learning about mindfulness from their health care provider. Parents with a college degree 49.6% (n=444) were more likely to report interest in learning about mindfulness from a health care provider compared to those without 37.1% (n=768; P<.001). Parents interested in learning about mindfulness were more likely to be male 62.6% (n=223; P<.001). There was no significant difference in interest in learning about mindfulness from a health care provider based on race.

Conclusions

This study indicates that many parents believe mindfulness can be beneficial while parenting and are interested in learning how mindfulness could help their child stay healthy. Findings suggest there is an opportunity to educate families about mindfulness practices.

Authors: Khader Yousef , Alyahya Mohammad , El-Khatib Ziad , Batieha Anwar , Al-Sheyab Nihaya , Shattnawi Khulood
Published: July 2021

BACKGROUND

The Jordan Stillbirth and Neonatal Mortality Surveillance (JSANDS) is an electronic surveillance system that automatically transfers the data on births, stillbirths, and neonatal deaths to the concerned authorities in the Ministry of Health. JSANDS was implemented and tested in 5 maternity hospitals during the period spanning May 2019 through December 2020.

OBJECTIVE

This study aimed to evaluate the usefulness and performance of JSANDS to register births, stillbirths, and neonatal deaths, and determine their causes. Specifically, this study examined the JSANDS attributes of acceptability, simplicity, flexibility, stability, representativeness, sustainability, penetration, data quality, sensitivity, and adoption.

METHODS

An evaluation study was conducted after 18 months of the JSANDS implementation using the Updated Guidelines for Evaluating Public Health Surveillance Systems. The evaluation focused on how well the system operated to meet its purpose and objectives. The indicators assessing the system attributes were scored on a Likert scale. Each indicator and overall attribute percentage score was represented as score rank and interpreted as excellent (score ≥80%), good (score ≥60 and <80%), average (score ≥40 and <60%), and poor (score <40%).

RESULTS

A total of 270 health care professionals participated in this study and evaluated the system performance. The system users rated the usefulness of JSANDS as excellent (percentage score=85.6%). The overall acceptability (percentage score=82.3%), flexibility (percentage score=80.2%), stability (percentage score=80.0%), and representativeness (percentage score=86.6%) were also rated excellent. The overall simplicity was scored good (percentage score=75.4%). All participants were trained on JSANDS and used it in the past 12 months. Of the 270 respondents, 219 (86.2%) reported that they intend to continue using the JSANDS system to register neonatal deaths and stillbirths in the future. All variables in JSANDS had complete data with no missing values.

CONCLUSIONS

The performance of JSANDS in registering all stillbirths and neonatal deaths as well as their causes was excellent. Almost all attributes and indicators of JSANDS functionality were rated excellent. JSANDS can be scaled up to cover all maternity hospitals in Jordan. The potential for scaling up the system is very high for many reasons, including its usefulness, simplified stillbirth and neonatal death review tools, and ease of the reporting process.

Most of the students (82.7%) mentioned that they could design and execute a research project as well as can write scientific articles. More than half of the respondents (66.4%) expressed an interest in participating in research. Almost all respondents (96.7%) agreed that research is beneficial as it aid in critical thinking and policy implementation. Almost two-third of respondents (79.8%) opined that education on research methodology is required in the medical curriculum. Majority of the respondents reported that inadequate time and priorities (89.1%), insufficient guidance (86.6%), inadequate familiarities with research methodology (87.5%) and statistical analysis (85.2%) were the barriers of research.

CONCLUSIONS

Findings of this study indicated that Bangladeshi medical students had a positive attitude toward research and they wish that research methodology should be taught in undergraduate medical education. In order to increase participation in research, the challenges identified by students may be addressed.
Osteoarthritis of the knee joint. Etiology, treatment, rehabilitation (analytical review of the literature)
Authors: Obeidat Khaled , Karpinska O.D.
Published: July 2021

According to epidemiological studies, osteoarthritis accounts for 10–12 % of all cases of musculoskeletal diseases. In the general structure of knee pathology, degenerative diseases make up 57.8 %. The urgency of the problems of gonarthrosis is due to not only its widespread prevalence, but also the high risk of developing knee dysfunction, accompanied by a significant reduction in the quality of life of patients and often leading to partial or permanent disability of patients. Gonarthrosis has significant gender features. Women account for about 70 % of the number of patients, while men had this disease almost 2 times less often, but other data indicate that the incidence of gonarthrosis in men under 60 years of age is higher, and in women it begins to increase after 65 years. Knee replacement is a leading method in the treatment of knee osteoarthritis stages III–IV. The tendency towards an increase in the total number of surgeries leads to an increase in the frequency of complications and unsatisfactory results: according to some authors, from 3.3 to 13.2% of patients complain of knee replacement outcomes. Studies of long-term complaints after arthroplasty have shown that in addition to pain reduction, some patients had an increase in varus angle when bending the knee while walking but they didn’t mark an improvement in gait parameters compared to preoperative examination. After unilateral total knee arthroplasty, the load patterns of the frontal plane in the operated knee remain pathological in the long run. After knee arthroplasty, there is muscle weakness, and studies have shown changes in all muscles of the lower extremity. Weakening of some muscles led to compensatory strengthening of others. Studies of the effect of preoperative rehabilitation on the outcome of knee arthroplasty have shown its low efficiency. Many studies have studied motor activity of patients after total knee arthroplasty in recent years. Not only gait features, but also movements of the pelvis, trunk and upper extremities are studied. Modern methods of diagnosing spatial oscillations of the body when walking have shown that disorders of body movements — excessive hand movements, pelvic loosening, asymmetrical flexion of the knee joints, etc., after arthroplasty are preserved in patients and restore slowly, and some disorders remain forever. Conclusions. Knee arthroplasty relieves pain, improves quality of life, but according to many authors, patients complain of incomplete restoration of the functionality of the prosthetic limb. According to the researchers, the main cause for incomplete reco-very of gait parameters is the difference in the frontal angles of the knee joint flexion and the difference in the length of the steps. Special training exercises can reduce the asymmetry of the steps, but it is difficult to completely restore the symmetry of the steps within 2 years. Studies of the effect of preoperative rehabilitation on the outcome of knee arthroplasty have shown its low effectiveness.
Microglia and mast cells: new targets for the treatment of chronic pain
Authors: Romanenko V.I.
Published: July 2021

The article is devoted to the problem of effective management of chronic pain. A review of the known mechanisms of development and maintenance of chronic pain and possible methods of influence is given. One of the reasons for the lack of chronic pain treatment effectiveness in some patients is the use of treatment regimens with drugs acting exclusively on the targets located in the nerve structures. Today an important role of microglia and mast cells in the development and maintenance of chronic pain conditions is well acknowledged. A new class of drugs from the group of acylethanolamides is described. One of the representatives of this group is palmitoylethanolamide. This drug may modulate the activity of microglia and mast cells, thus increasing the pain threshold and the effectiveness of therapy. The use of palmitoylethanolamide in patients with chronic pain can increase the effectiveness of therapy.
Modic changes in the lumbar spine: histology, risk factors, clinical presentation and treatment
Authors: Shapovalov V.S. , Bystrytska M.A. , Dedukh N.V. , Balyk O.I.
Published: July 2021

The article presents a literature review on the Modic changes (MCs) in the vertebral endplates, which are frequently detected in patients with chronic low back pain. The etiology of MCs is unknown; however, there are three causes which are considered the most probable today: mechanical, infectious and biochemical. They share a common mechanism of pro-inflammatory molecule migration from the degenerative disk. A close association has been identified and described between the MCs and a non-specific chronic low back pain. Disc degeneration exerts a further stress on the endplates and produces microcracks, through which the inflammatory mediators enter the bone marrow and provoke the MCs. At present, there are no evidence-based treatment protocols for the MCs. A certain progress has been made with antibiotic therapy, injections of steroids and antiresorbents; the effectiveness of anti-TNF-α therapy is being explored. The sporadic reference data on our disposal indicate that patients with MCs and chronic low back pain, along with instability, who do not respond to a conservative treatment, may be referred for the surgical treatment to relieve pain and improve quality of life. However, not all of the presented methods of surgical treatment with chronic back pain are effective in patients with the Modic changes. The divergence of patient treatment outcomes presented by various sources indicates the need for a further research to understand the MC pathogenesis and develop pathogenetic approaches to the treatment of this pathology.

Published: July 2021

Over the years, more and more households are beginning to have pets. So, the most important issue recently was how to raise pets in an easy way. In today’s world, there is a growing focus on the regular interactions between human and physical devices. This paper introduces a smart pet monitoring and feeding system that is working in an environment of Internet of Things (IoT). Pet feeders came into existence as pet owners found it difficult to cater time to feed their pets. This system allows the owner to schedule and manage feeding times, portion sizes, and food supply for pets. They are controllable on smartphones using blynk and computers in order to feed them even when owners are away. The food dispensing mechanism is performed by the servomotor. It allows the user to monitor the pets using IP camera. A voice recording module is interfaced to the Arduino Uno with the owner’s voice recording for calling the pets at the meal time. Automatic water refilling has been designed and implemented along with the food dispenser.It offers new and developed way of feeding pets without the need of human intervention with refill alert and feeding alert. . Using smart pet feeder in houses will assure pet owners and increase comfort and peace of mind. Especially when we are unavailable for them.

Efficient Memory-based Multiplier Technique for SWL DSP Systems
Authors: Kumar B Ajay
Published: July 2021

The DSP systems usually deal with a lot of multiplications as it is dealt with many discrete signals. The combinational circuits consume a lot of power as there are many intermediate blocks (i.e., usually full adders & and gates). The combinational circuits take more area and the delay is also more. Usually there is a tradeoff between area and delay. To make the multiplier more efficient we usually prefer memory-based multiplier. Different types of techniques are there in memory-based multipliers like the APC (anti-symmetric product coding), OMS (odd multiple storage) etc. In these techniques LUT based storage is used. The multiplied products are stored efficiently based on the technique used to store the data. To optimize the memory required we combine the APC and OMS technique for better storage and retrieval of data. In this project we show how combined technique increases the performance of multiplier. The suggested combined technique reduces the size of the LUT to one-fourth that of a standard LUT. It is demonstrated that the proposed LUT architecture for tiny input sizes can be used to execute high-precision multiplication with input operand decomposition in an efficient manner.
Investigation on Surface Roughness during Milling of AL-61 Machining under Minimum Quantity Lubrication (MQL)
Authors: Singh Er. Sher
Published: July 2021

In modern production industries, main focus is on high productivity with best surface finish. For this purpose use of cutting fluid in machining of component plays major role in controlling the surface finish of components. The cutting fluids are generally applied continually during machining i.e. wet or flooded machining. The dry machining yields poor surface finish and less tool life whereas wet machining results in better surface finish as well as longer tool life. But continuous lubrication involves very large amount of consumption of cutting fluids which cause health hazards of machining operator and ill effects on environment. Moreover, continuous lubrication contributes to increase in total production cost of product. Hence, the Minimum Quantity Lubrication(MQL) is needed nowadays which works with less amount of cutting fluid (100-1000ml/hr) with pressurized air (as mist form) as compare wet machining (amount of cutting fluid 400-500L/hr approx.). The study focus on comparison of surface roughness behavior of AL-6061 under different lubrication conditions i.e. Dry, Wet and MQL. The experimental work performed on CNC milling machine involving cutting parameters feed rate, spindle speed and depth of cut as input parameters, where surface roughness and microstructure of specimens were observed as output parameters in the experiment. The machined components under different conditions i.e. DCM (dry cutting machining), MQL (minimum quantity lubrication), WCM (wet cutting machining) were examined for surface roughness using R-10 surface roughness tester whereas microstructure analysis was done using optical microscope. For given cutting parameters at 2000RPM spindle speed, 200mm/min. feed rate and it is found that better result of MQL from the dry machining and nearest of wet machining.

Published: July 2021

In today’s competitive business world, it is extremely important for decision makers to have access to decision support tools in order to make quick, right and accurate decisions. One of these decision-making areas is supplier or service provider selection. Supplier selection is a multi – criteria decision making process that deals with the optimization of conflicting objectives such as quality, services, cost, and delivery time. Although numbers of multiple criteria decisions making (MCDM) methods are available for solving MCDM problem, it’s observed that in most of these methods the ranking results are very sensitive. This work proposes a multi-criteria decision making (MCDM) based framework that is used to evaluate supplier selection by using an entropy weight method (EWM) for calculation of weightage of each criterion, once the weightage is calculated the EWM is combined with Proximity Indexed Value (PIV) Method for calculating the supplier rank. Finally, the ranking performance of PIV method is compared with other MCDM Methods for same set of alternative and criterions. A numerical example along with graphical illustrations is considered and comparison analysis is provided to test the feasibility of the proposed method. In the illustrative example a manufacturing firm is looking for select most suitable supplier for supply among the ten-supplier based on four different criteria such as Price/Cost, Service, Quality and Delivery, in which Price/Cost is non-beneficial and the attributes pertaining to other criteria are beneficial one.

The Biomass is the electricity generation unit and is developed from organic material and renewable and sustainable source of energy. It is used to create the electricity or the other form of power. It is carbon neutral electricity and generated from the renewable organic waste that would otherwise be dumped in the landfills, openly burned and left as fodder for the forest fire. In biomass power station, the wood waste and other waste is burned to produce steam that run a turbine to generated the electricity and provides heat to homes and industries. The main aim of hazard analysis and risk assessment in Biomass power station is to analysis and identified the physical, chemical and biological and environmental hazard and calculate the consequence and the frequency of the hazardous event. The risk level is also help and analysing the hazard and the required safety control to minimize the risk and eliminate the Hazards.
Prevalence of Pollen Allergy in Rural Telangana (Bhongir) and the Need for Continuous Monitoring of Allergens - A Pilot Study
Authors: . Namreen
Published: July 2021

Prevalence of pollen allergies in the rural population of Telangana is under-studied. The objective of this work was to estimate the prevalence of pollen allergy in the rural town of Bhongir, Telangana and to evaluate the need for further investigation of environmental effects on the onset of pollen allergies. A pilot survey was conducted among fifty randomly selected individuals of Kisan nagar area in Bhongir, Telangana (India) and its nearby localities using a questionnaire. Patients with known allergies were further asked to provide information about their allergic conditions and treatment. Six out of the fifty participants (CI: 1.5-10.5) were found to be allergic to pollen. The allergic participants did not have symptoms from birth but rather developed them during the later stages of life. The study also identified the potential pollen allergens in the locality which might be the cause of the allergies in the affected individuals. Furthermore, the study revealed that the commonly recommended medications were neither the preventive measures nor the permanent cure against the symptoms of pollen allergy. The results suggest a trend of rural youth with no genetic predisposition, developing pollen allergies due to environmental sensitization. The study highlights the need for the establishment of regional monitoring stations, and future studies with larger samples to understand the sensitization pathways to help the locals take preventative measures.
About the B-spline wavelet discrete-continual finite element method of the local plate analysis

Published: July 2021

Introduction. This distinctive paper addresses the local semi-analytical solution to the problem of plate analysis. Isotropic plates featuring the regularity (constancy) of physical and geometric parameters (modulus of elasticity of the plate material, Poisson’s ratio of the plate material, dimensions of the cross section of the plate) along one direction (dimension) are under consideration. This direction is conventionally called the basic direction.

Materials and methods. The B-spline wavelet discrete-continual finite element method (DCFEM) is used. The initial operational formulation of the problem was constructed using the theory of distribution and the so-called method of extended domain, proposed by Prof. Alexander B. Zolotov.

Results. Some relevant issues of construction of normalized basis functions of the B-spline are considered; the technique of approximation of corresponding vector functions and operators within DCFEM is described. The problem remains continual if analyzed along the basic direction, and its exact analytical solution can be obtained, whereas the finite element approximation is used in combination with a wavelet analysis apparatus in respect of the non-basic direction. As a result, we can obtain a discrete-continual formulation of the problem. Thus, we have a multi-point (in particular, two-point) boundary problem for the first-order system of ordinary differential equations with constant coefficients. A special correct analytical method of solving such problems was developed, described and verified in the numerous papers of the co-authors. In particular, we consider the simplest sample analysis of a plate (rectangular in plan) fixed along the side faces exposed to the influence of the load concentrated in the center of the plate.

Conclusions. The solution to the verification problem obtained using the proposed version of wavelet-based DCFEM was in good agreement with the solution obtained using the conventional finite element method (the corresponding solutions were constructed with and without localization; these solutions almost completely coincided, while the advantages of the numerical-analytical approach were quite obvious). It is shown that the use of B-splines of various degrees within wavelet-based DCFEM leads to a significant reduction in the number of unknowns.
Dismantling a multi-storey building in the conditions of a built-up area: engineering and economic indicators
Authors: Mazurin Dmitry M. , Dement’eva Мarina E.
Published: July 2021

Introduction. In the contemporary world, the number of multi-storey and high-rise buildings goes up, and this is the case of central districts of large cities. This renewal of built environments in megalopolises takes the form of development of unoccupied spaces, which grow smaller year after year, and liquidation of buildings whose life cycle is coming to an end. In this regard, there arises a problem of choosing the building demolition method, since traditional techniques, used worldwide, do not allow for the liquidation of buildings that have more than 15 floors. Therefore, given the growing number of floors, densely built-up areas, and tighter safety regulations, there is a need to improve dismantling technologies, including tighter environmental safety requirements applied to dismantling works, and this necessity substantiates the relevance of this research. The subject of this work is the engineering and economic indicators of the element-wise deconstruction and mechanical demolition, performed as a sequential set of works that end in the elimination of a multi-storey building, having various design features. The purpose of this study is to explore the engineering and economic indicators of dismantling works carried out in densely built-up urban areas, taking into account work arrangement features, space-planning and design characteristics of a building to be liquidated.

Materials and methods. Given the findings of the field observations that represent photographic recording and timing, measurements were taken in respect of the time needed to perform the dismantling work in the process of liquidation of a multi-storey building. The method of mathematical analysis was employed to obtain the engineering and economic indicators of dismantling works. The work space, the scope and amount of work were identified using AutoCAD, a 2D modeling system.

Results. The co-authors have identified the features of the element-wise dismantling and mechanical demolition of a multi-storey building, dependences between engineering and economic indicators, as well as the characteristics of buildings.

Conclusions. The research, performed by the co-authors, allow to identify the bottlenecks of such methods of dismantling a multi-storey building, as its element-wise dismantling and mechanical demolition. The results of the work can be used to streamline the building dismantling technology, with regard to the features of surrounding buildings and the characteristics of the building to be liquidated.
