Sink Node Placement and Partial Connectivity in Wireless Sensor Networks.

This research delves into the aspects of communication and connectivity problems within random Wireless Sensor Networks (WSNs). It takes into account the distinctive role of the sink node, its placement, and application-specific requirements for effective communication while conserving valuable network resources. Through mathematical modeling, theoretical analysis, and simulation evaluations, we derive, compare, and contrast the probabilities of partial and full connectivity within a random WSN, factoring in network parameters and the maximum allowable hop distance/count hmax. hmax captures the diverse range of delay-sensitive requirements encountered in practical scenarios. Our research underscores the significant impact of the sink node and its placement on network connectivity and the sensor connection rate. The results exemplify a noteworthy decline in the sensor connection rate, dropping from 98.8% to 72.5%, upon relocating the sink node from the network center to the periphery. Moreover, as compared with full connectivity, partial connectivity and the sensor connection rate are more suitable metrics for assessing the communication capability of random WSNs. The results illustrate that 1.367 times more energy is required to connect less than 4% of the remote sensors, based on the examined network settings. Additionally, to increase the sensor connection rate slightly from 96% to 100%, an additional 538% more energy is required in multipath fading based on the widely adopted energy consumption model. This research and its outcomes contribute to establishing appropriate performance metrics and determining critical network parameters for the practical design and implementation of real-world wireless sensor networks.

Analysis of the Mechanical Characteristics of Tunnels Under the Coupling Effect of Submarine Active Faults and Ground Vibrations

With the rapid development of modern transportation construction, the construction of cross-harbor tunnels has solved the problem of traffic connection between cross-straits, bays and islands. The construction of sub-sea tunnels has technical difficulties such as high difficulty of marine geological survey, close hydraulic connection between strata and seawater, and more developed adverse geology. Based on this, this paper studies the mechanical characteristics of the submarine tunnel under seismic action at the active fault. Firstly, the mechanical model of the universal fault interface is established, and the calculation model of the fault interface is theoretically derived by the method of vibration mechanics, and the influence of the change of the strength of the contact surface and the stiffness of the surrounding rock on both sides of the fault on the transfer coefficient is obtained. Secondly, based on the ground motion input method of two-dimensional homogeneous half-space field, the relevant program of viscoelastic artificial boundary ground motion input is written by MATLAB program, which lays the foundation and premise of load input for mechanical response calculation. Finally, the outcomes of the tunnel parameters and the interplay between the tunnel and the surrounding rock on the cracking of the tunnel lining shape and the mechanical response of the cross-fault sub-sea tunnel underneath seismic motion are mentioned, and it is concluded that the increase in seismic intensity for different seismic intensities under the sea floor has an essentially constant proportion to the increase in acceleration of the seismic response; the seepage effect under the sea floor for the tunnel lining structure reduces the seismic response displacement, velocity and The seabed seepage for the tunnel lining structure reduces the peak seismic response displacement, velocity and acceleration by about 20–35%.

26 Remotely Training Research Assistants in other Countries to Conduct Neuropsychological Tests: Lessons Learned

Objective:Technological advances allow for increased international collaboration within the medical community (e.g., internet, e-mail, instant messaging, video-teleconferencing [VTC]). Partnering with clinicians and researchers across the globe allows for shared resources, particularly beneficial for underserved populations and communities with poor access to specialty resources, including neuropsychology. Along with the potential benefits of such collaborations comes challenges including language, cultural, and physical barriers. The presented findings detail important lessons learned from an ongoing research collaboration between the Einstein team (Bronx, NY) and a research group in Kerala, India, called the Kerala Einstein Study (KES), a study evaluating pre-dementia syndromes in Indian older adults. Here we highlight the training process of research assistants administering neuropsychological measures to older adults in India, by neuropsychologists in the USA.Participants and Methods:One study manager and several research assistants (collectively referred to as RAs) based in India were trained by the first author, a neuropsychology postdoctoral fellow (MS) based in the US via VTC (i.e., Zoom), under supervision of a clinical neuropsychologist. RAs were trained in test administration and scoring for a variety of neuropsychological measures. RAs speak Malayalam and English; training occurred in English. Following training, VTC meetings were held to process testing experience and channels were created for ongoing administration/scoring questions and concerns (i.e., email, WhatsApp). RAs scanned and uploaded scored protocols to a protected web-based platform. MS double-scored several protocols and additional VTC meetings were held to discuss/update scoring procedures.Results:Physical challenges included time difference between sites, internet connectivity, language barriers (i.e., varying English dialects) cultural considerations (e.g., some test/task directions were changed based on RAs knowledge of more appropriate wording). Test administration challenges included cultural factors (i.e., allowing for continuation of some tasks beyond time limits for rapport) and RA comfort level with administration of some tasks (e.g., trail making test). Scoring challenges included RAs tendency to score too strictly or leniently and confusion regarding specific scoring criteria. At an initial VTC meeting, MS modeled test administration. Then RAs practiced the tests together. To reduce challenges including time difference, connectivity problems, language barriers, and comfort with testing/scoring, VTC training sessions were scheduled individually between MS and each RA. During these sessions, the RA 'tested’ MS and received immediate feedback. Most sessions lasted approximately 90 minutes with one RA requiring a second session (i.e., sessions were tailored for individuals to obtain level of testing comfortability and competency). After each RA was 'cleared’ by MS to start testing, RAs began testing and scoring. Following MS’s review of several scored protocols, meetings took place in groups in order to improve scoring skills and increase consistency between RAs. Given the continued high degree in scoring variability, a third RA was hired with one of his main responsibilities being to double score all protocols.Conclusions:Findings highlight important challenges and considerations for remotely training study personnel to administer neuropsychological measures (i.e., RAs in India and neuropsychologists in the USA). Important steps to reduce identified barriers included individualized training sessions, specific training in scoring, and open/ongoing communication channels.

Random site percolation thresholds on square lattice for complex neighborhoods containing sites up to the sixth coordination zone

The site percolation problem is one of the core topics in statistical physics. Evaluation of the percolation threshold, which separates two phases (sometimes described as conducting and insulating), is useful for a range of problems from core condensed matter to interdisciplinary application of statistical physics in epidemiology or other transportation or connectivity problems. In this paper with Newman–Ziff fast Monte Carlo algorithm and finite-size scaling theory the random site percolation thresholds pc for a square lattice with complex neighborhoods containing sites from the sixth coordination zone are computed. Complex neighborhoods are those that contain sites from various coordination zones (which are not necessarily compact). We also present the source codes of the appropriate procedures (written in C) to be replaced in original Newman–Ziff code. Similar to results previously found for the honeycomb lattice, the percolation thresholds for complex neighborhoods on a square lattice follow the power law pc(ζ)∝ζ−γ2 with γ2=0.5454(60), where ζ=∑iziri is the weighted distance of sites in complex neighborhoods (ri and zi are the distance from the central site and the number of sites in the coordination zone i, respectively).

Dispersed urban growth in the intermediate city and its impact on public space. A case study in Loja- Ecuador

INTRODUCTION Urban growth in intermediate Latin American cities has given way to low-density, discontinuous peripheries. This uneven development negatively impacts the urban environment and quality of life. In this context, public spaces do not fulfill their structural function, they fail to generate connections between soil uses, recreation areas, and social exchange. OBJECTIVE This study proposes to fill a gap in existing research by focusing on the incidence of dispersed urban growth specifically in public space through the study case analysis. METHODOLOGY Using a descriptive and qualitative approach, dispersed urban growth is analyzed multidimensionally and the networks of public spaces are evacuated in terms of form, accessibility, uses, sociability, and identification. RESULTS The study area presents low and very low densities in about 70% of its area, soil and 30% of the area presents a continuity of the fabric and 76% of the area is intended for land use in this way it is evident that urban growth dispersion focuses on problems of connectivity, fragmentation, segregation, the marginalization that limit access to public space. DISCUSIÓN AND CONCLUSIONS The low density and limited diversity of users, erode social and economic dynamics, in this sense, the public space of the periphery limits its function to a minimum which deteriorates it further instead of contributing to urban quality.

Tensor and Confident Information Coverage Based Reliability Evaluation for Large-Scale Intelligent Transportation Wireless Sensor Networks

Wireless sensor network (WSN) plays an important role in information collection and processing in Intelligent Transportation Systems (ITS) recently. With rapid development of ITS, the size and complexity of WSN is rapidly increasing. Thus, how to evaluate the reliability of large-scale WSN has attracted more and more attention. In this paper, reliability is defined as the probability that the WSN is functional. A confident information coverage (CIC) model-based reliability algorithm (CICRA) is proposed to comprehensively consider coverage reliability and connectivity reliability. Especially, to determine the impact of failing nodes on connectivity in large-scale WSN, a grid clustering connectivity algorithm (GCCA) is proposed to reduce the complexity of computing the connectivity between large-scale wireless sensor nodes, which transforms the connectivity problem between nodes into a grid connectivity problem. In addition, a 3-order tensor modeling is proposed to uniformly represent and model node states, node combinations, and coverage patterns. Furthermore, the network reliability combines coverage reliability and connectivity reliability is evaluated by tensor modeling. Simulation results indicate that the proposed CICRA can improve the network reliability and accuracy of reliability evaluation.

Tele-mental health during the COVID-19 pandemic: A systematic review of the literature focused on technical aspects and challenges.

Mental disorders are the leading cause of disability and the second leading cause of death worldwide, which leads to the death of more than 9 million people annually. The global impact of the Coronavirus epidemic on mental health includes insomnia, anxiety, and depression. Therefore, given the current situation, innovations such as telemedicine to provide prevention and treatment services for people with mental disorders seem necessary. A literature review was performed according to the preferred items to report in systematic reviews and meta-analyses (PRISMA). Covering a period from January 2020 to July 2023, we conducted a systematic literature search on five electronic databases (PubMed-Mesh, Scopus, Web of Science, Science direct, and PsycInfo). The search strategy included three categories of keywords: Mental health, Tele, COVID-19. A total of 112 articles were identified by searching the databases of published articles, 13 articles met our inclusion criteria. A total of 76.2% of them were related to patients with stress, anxiety, and depression issues. We found that the real-time method has been the most common method used to communicate between the physician and the patient (92.3%). The communication technologies used also included telephone, video call, video conference, and E-mail. During these communications, data was exchanged in text, voice, and video formats. In three studies (27%), interoperability with other systems was mentioned. In addition, 69.2% of the studies reported challenges, the most important of which were access to electronic and communication devices, network connection problems, audio and video problems, and privacy issues. Considering the many advantages of telemedicine technology in the field of mental health, the need to use this technology in developing countries, including our country, is obvious. But the application of these technologies requires the investigation of technical aspects and challenges related to them as much as possible, which have been seen in few studies.

The Drawbacks of Online Hybrid Education in Malaysia

In Malaysia, the educational landscape has undergone a considerable change as a result of the COVID-19 pandemic and the quick development of technology, which has prompted the implementation of online hybrid education models. This strategy has several advantages, such as flexibility and accessibility, but it also has some disadvantages. The main disadvantages of online hybrid education in Malaysia are summarised in this abstract. Digital inequality makes it difficult for students from lower income groups and from rural areas to fully engage in online learning activities and exacerbates existing educational disparities due to lack of access to the digital gadgets and dependable internet connectivity. It might also be arduous for students to concentrate on their studies when there aren't any face-to-face interactions, henceforth causing feelings of isolation. Some teachers will find it difficult to modify their teaching strategies for the online setting hampered by the absence of practical, hands-on activities and real-time feedback. Students may also face technical difficulties, such as software bugs or connectivity problems which may obstruct learning and cause irritation in both students and teachers. Maintaining assessment integrity in a hybrid online education environment can be difficult because cheating, plagiarism and impartiality of assessments are harder to catch. Online hybrid virtual education may restrict students' emotional and social growth and limit their interpersonal skills and the capacity for peer collaboration. Furthermore, it can be difficult to communicate and restrict the amount of help and direction that educators can offer to virtual students. In conclusion, while hybrid online education in Malaysia has some benefits, there are also some problems that need to be recognised and addressed. Therefore, it is important to work to close the digital divide and improve the standard of online learning by blending digital education with a physical approach to produce truly educated and skilled students.

IMPACT ON EDUCATION DURING COVID-19 PANDEMIC

The argument given in the article reflects how the education system has been affected due to the Pandemic. Education is not only a fundamental human right; it is the key driver of sustainable development and progress. When the education system breaks down, then growth and peace cannot be sustained in any society. The COVID-19 pandemic has pushed the world into the deepest global recession in living memory, which will have lasting effects on people’s lives, in the education sector, economies, and health care sectors. During the COVID-19 epidemic, providing and using an online environment has emerged as the primary problem for many educational institutions, including universities. As a result, teachers encountered difficulties managing their online classes and dealing with connectivity problems throughout COVID-19. It has been observed that educators also lack information and communication technology literacy.

Modelling and capacity allocation optimization of a combined pumped storage/wind/photovoltaic/hydrogen production system based on the consumption of surplus wind and photovoltaics and reduction of hydrogen production cost

To achieve “carbon neutrality”, clean energy such as wind and solar energy is being developed, but due to the random and intermittent characteristics of wind energy and photovoltaics, the instability of grid connections and the abandoning wind and photovoltaics need to be addressed urgently. This paper proposes a method to solve the problems of grid connection and abandonment in wind and photovoltaic generation systems, that is, to establish a combined pumped storage/wind/photovoltaic/hydrogen production system through the pumped storage and hydrogen production system. The system consists of a pumped storage/wind/photovoltaic complementary subsystem and a hydrogen production subsystem. First, different models in the system are modelled using Simulink and the characteristics of the models are analysed. Subsequently, the wind turbine model and the PV model are simulated to derive the wind-PV complementary characteristic curves, and it is found that the load demand cannot be met by relying on wind-PV complementary power generation alone. To achieve system stability and economy, pumped storage is configured to smooth the output of wind power and PV. After comprehensive consideration, the optimal pumped storage capacity is determined to be 1000 MW. Then, through the simulation of the pumped storage/wind/photovoltaic system, it is found that even though pumped storage can absorb the wind and photovoltaic outputs, there is still a surplus when the wind and photovoltaic outputs are in excess. Therefore, this surplus energy is used for hydrogen production and the configuration of the hydrogen production system is optimized using a particle swarm algorithm to minimize the cost per unit of hydrogen production. After particle swarm optimization, it was determined that the unit cost of hydrogen production was minimized to 3.54 CNY/Nm3 for the configuration of 55 electrolysis tanks of 4 MW and 219 lead-acid tanks of 1 MW/2 MWh. Meanwhile, the electrolysis tank simulation model and the lead-acid battery simulation model were used to obtain maps of their operating conditions, hydrogen production and hydrogen storage tank pressure. In view of the addition of an energy storage system to the wind and photovoltaic generation system, this paper comprehensively considers the two energy storage modes of pumped storage and hydrogen production, and proposes a corresponding capacity optimization configuration scheme, which has reference value for improving the consumption and stability of wind and photovoltaics and realizing the sustainable utilization of clean energy.

Computation-guided design of flexible piezoelectric composites by optimizing charge-stress transmission

Flexible piezoelectric materials have attracted increasing attention as active components in wearable and flexible electronics, soft robotics and artificial skins or muscles. Although constructing polymer-based composites is becoming a common solution to balance their piezoelectricity and flexibility, challenges associated with the electrical and mechanical mismatch between the polymer matrix and the ceramic fillers remain. Here, taking the piezoelectric composite of lead zirconate titanate-polydimethylsiloxane (PZT/PDMS) as the example, we perform phase-field simulations to spatially and temporally study the electrical and mechanical response. It is found that good connectivity of fillers could provide a load transfer path and break topological restriction of filler morphology on polarization dipoles. Then, we propose an interface design strategy to address the mismatch problem in ‘3–3’ composites, which could greatly enhance the overall piezoelectric response under different modes of compressing, stretching and bending. Finally, we experimentally fabricate high-performance flexible composites with an ultrahigh piezoelectric charge coefficient of 155 pC N−1 and a low Young’s modulus of 63 MPa. This research offers a promising route for designing flexible piezoelectric composites by synergistically regulating connectivity and mismatch problems, which is also expected to guide the optimization of other actuators or sensors related with electromechanical coupling effect.

Hybrid Energy Storage Power Allocation Strategy for Stabilizing Wind Power Fluctuations

In order to solve the problem of energy shortage, renewable energy such as wind power has developed rapidly worldwide. However, due to its time-varying and uncertain nature, wind power is prone to local fluctuations and operational safety hazards when connected to the power grid. In response to the stable grid connection problem of wind power generation, a hybrid energy storage system is proposed A method was proposed to achieve smooth power fluctuations in wind power generation using a model, and a charging and discharging control and allocation method for energy storage was proposed. Firstly, the preliminary power of hybrid energy storage was obtained using the model predictive control method, Then, an adaptive variational mode decomposition method was used to achieve energy distribution between batteries and supercapacitors. Finally, the measured data of a 100MW wind power plant in Xinjiang was analyzed as an example. The proposed method has been validated to not only achieve reasonable power allocation between hybrid energy storage systems, but also effectively reduce the impact of wind power generation on the power grid, achieving long-term safe operation of hybrid energy storage systems.

Research on modeling joining and joining modification method of hybrid FE-SEA model

Since the connection method at the boundary of the hybrid FE-SEA (finite element-statistical energy analysis, FE-SEA) model affects the overall calculation accuracy of the model, the missing or inaccurate connection relation will lead to a large error in the model calculation. In order to effectively solve the calculation error caused by the connection problem of hybrid FE-SEA model, this paper starts from the modeling methods and connection relations of “hybrid-point” connection, “hybrid-line” connection and “hybrid-surface” connection. In order to solve the modeling method and correction problems of the “hybrid-point” connection in the hybrid FE-SEA model, the “out-of-plane” wave motion equation at the “hybrid-point” connection was established by using the superposition principle of plane waveforms in polar coordinate system. The “hybrid-point” connection and wave-number relation in Cartesian coordinate system are studied. The radiation radius correction method of “hybrid-point” connection is proposed. An example is given to verify the effectiveness of the method. In order to solve the modeling and correction problem of “hybrid-line” in hybrid model, a “hybrid-line” connected triangular waveform function model was established by using the method of linear difference. The direct field dynamic stiffness matrix of “hybrid-line” connection in node coordinate system is studied. According to the shape function of the “hybrid-line” connection wavenumber space, a method to correct the shape function of the “hybrid-line” connection is proposed, and the validity of the method is verified.

Systemic observation and measurement of microgap formation in dental implant–abutment connection interface under fatigue

Abstract Today, a variety of implant designs with different attachment types are widely used in dental implant systems to eliminate connection problems. However, there are still design issues that can significantly affect the long-term success of dental implants. One of these problems is the formation of a microgap in the abutment–implant interface, which can lead to abutment screw loosening, screw fracture, and abutment fracture under masticatory loading. In this in vitro study, the effects of gingival height, dental implant diameter, and abutment type (solid, digital, and ball) on microgap formation were observed after repetitive fatigue tests using an experimental design. After the tests, the optimal design factors were determined to minimize microgap formation. According to the results of the experimental design, the abutment type was found to be the most influential parameter on microgap formation. An implant diameter of 4.1 mm, the smallest gingival height of 0.5 mm, and a digital attachment combination were identified as the optimal design parameters based on the statistical approach (R 2 = 85.3 %).

Covid-19 Pandemi Sürecinde Hemşirelik Öğrencilerinin Ailelerinin Uzaktan Eğitimle İlgili Görüşleri

Aim: Distance education is an interdisciplinary field that aims to remove the limitation between educator, learner, and learning resources and of uses existing information and communication technologies for this purpose. Maintaining social distance, especially during the pandemic, has been instrumental in protecting and maintaining the health of both students and educators. However, distance education's entry into our lives as a necessity during the pandemic has brought many problems. The fact that the education environment left the classroom and came into the home, and that time shared with family members is now used for education, makes it necessary to conduct studies to determine families' experiences, attitudes, and opinions about distance education. This study aimed at determining families’ opinions of undergraduate and graduate nursing students on distance education during the Covid-19 pandemic. Methods: This is a descriptive and cross-sectional study. The study was conducted with 407 participants. The data were collected between the 9th and 10th months of the pandemic, with the data collection tool developed by the researchers. Results: The families have a negative opinion on distance education, and these opinions were affected by their negative experiences and problems. The families found the low costs and the increased time the students spent with their families to be positive aspects of distance education. The families complained about connection problems, the student spending too much time on the computer and about the home environment needing to be more suitable for education. However, negative opinions of the families included that distance education is insufficient in conveying professional skills and that distance education is not suitable for nursing education. The opinions of Y-generation family members, those with graduate education, and those with a permanent internet connection at home had more positive opinions than the others. Conclusions: Distance education has become an integral part of our lives. Therefore, it is essential to unearth problems regarding distance education and develop solutions. Study results on the opinions, attitudes, and experiences of all distance education stakeholders will contribute to distance education practices.

Beliefs and expectations of patients with fibromyalgia about telerehabilitation during Covid-19 pandemic: A qualitative study

BackgroundTelerehabilitation as an alternative to physiotherapeutic care has been increasingly implemented in diverse populations. However, this mode of service can evoke beliefs and expectations in patients with fibromyalgia, depending on sociocultural and clinical context, that can cause poor adaptation and dropout from treatment. ObjectiveTo explore beliefs and expectations of individuals with fibromyalgia about physical exercises delivered through telerehabilitation. MethodsThirty individual semi-structured interviews were conducted via videoconference with women with fibromyalgia recruited during COVID-19 pandemic through intentional sampling. These interviews were guided by four questions addressing the beliefs and expectations about telerehabilitation. The interviews were recorded after consent and transcribed using the MAXQDA® software. The inductive approach was performed in which raw data were coded into categories and subcategories. ResultsParticipants expect to benefit from telerehabilitation due to flexible hours, no need of travel, socialization, and lower risk of contamination. However, they believe they have difficulties related to the physical absence of the therapist, complexity of the exercises, internet connection problems, adaptation to the domestic routine and availability of schedules. ConclusionWomen with fibromyalgia showed positive expectations about telerehabilitation, relating better socialization with other individuals diagnosed with fibromyalgia, home care with flexible schedule and, to provide needed service to underserved. However, they listed barriers such as the physical absence of the therapist and instability of the internet connection and, the FM symptoms themselves.
