An Efficient Routing Awareness Based Scheduling Approach in Energy Harvesting Wireless Sensor Networks

Wireless sensor networks (WSNs) have emerged as a promising technology for various Internet of Things (IoT)-based sensing applications. Generally, sensor nodes are powered by non-rechargeable and low-capacity batteries; they only last for a small amount of time. Due to their dispersed nature, sensor nodes cannot have their batteries replaced or maintained locally. The energy harvesting (EH) concept shows commitment as a method for addressing the current energy shortage. Another problem is the intra-energy control of various network load functions, including coverage preservation, routing, clustering, etc. This study proposes an ERAS (efficient routing awareness scheduling) algorithm to address the abovementioned issues. The ERAS method employs a solar harvesting system as a hierarchical clustering-based routing protocol. The presented scheme dynamically alters nodes between states and adjusts to new states based on the insides of sensed data packets. Synchronization-based scheduling ensures proper coordination between the cluster head (CH) and cluster members (CMs). It selects the CH based on both remaining and harvested energy and the number of active nodes to improve throughput. Surprisingly proposed EASR algorithm performs efficiently while considering various performance matrices, including network lifetime, packet delivery ratio, energy consumption, and network sustainability. Extensive simulation results exhibit the network lifetime of the proposed ERAS technique (79.8%) compared to ERA, SEED and CREST methods as 67.3%, 73.8%, and 75.2%, respectively.

Optimizers for optimal coordination of distance relays and non-standard characteristics of directional overcurrent relays

In this paper, different methods are utilized to solve the coordination issue involving directional overcurrent relays (DOCRs) and distance relays. The proper coordination of DOCRs and distance relays is a critical issue for system security in electrical networks. Finding the DOCRs setting, pickup current(Ip) and timed dial setting (TDS), and operating time for zone-2 of distance relays is the primary objective of solving the coordination problem. The constant parameters A & B of the directional overcurrent relay that are responsible to control the form of the relay´s characteristics as well as the Ip and TDS have been regarded as variables in this problem. The optimal value for these four DOCR settings has been determined using different optimization techniques. The primary and backup relays must operate sequentially and without any violations, and this must be guaranteed by optimization techniques. In order to determine the operation time for zone-2 and DOCRs setting, optimization methods are examined utilizing the 8-bus and IEEE 30-bus networks. Different optimization algorithms, including recent and traditional techniques, are compared. The obtained results show the superiority of the genetic algorithm (GA) in solving the coordination problem of distance relays and DOCRs. Also, the obtained results prove the ability of the GA method compared to the particle swarm algorithm (PSO), grey wolf optimization (GWO), water cycle technique (WCA), equilibrium optimizer (EO), African vultures optimization algorithm (AVOA), flow direction algorithm (FDA), and gorilla troops optimizer (GTO) techniques.

Dynamic and Model Predictive Controllers for Frequency Regulation of an Isolated Micro—Grid with Electrical Vehicles and the ESS Integration

Electric vehicles (EVs) improve the performance of Energy Storage Systems (ESS). The inclusion of electric vehicles in the microgrid system has attracted considerable attention due to the emerging potential of vehicle-to-grid options. The proper coordination among ESS & EVs has a high capacity to tolerate frequency discrepancies and the functioning of the MG (Micro-Grid). In this research, two innovative control techniques-To address the issue of frequency regulation in the standalone MG, Model Predictive Control (MPC) and Dynamical Droop Control (D2C) are linked to affect the structure of ESS and EVs following extensive RES inclusion or a significant change in load demand. The D2C protects EV energy in line with system demands by preserving the least amount of power for anticipated EV demand. Combined MPC and D2C settings are tuned using a complex evolutionary technique to further improve performance. In MATLAB/Simulink, a single MG (micro-Grid) is modeled and evaluated using the controlling strategies indicated above. As well, a range of case papers is taken into account to confirm the integration of the D2C and MPC for a single MG's modulation scheme. Moreover, the MPC outperforms both fuzzy-based proportional-integral (FPI) and proportional-integral (PI) controllers in terms of performance results.

CONCEPTUAL APPARATUS OF HISTORICAL SCIENCE IN UKRAINE IN THE LIGHT OF MODERN METHODOLOGICAL RESEARCH

In the proposed article, an attempt was made to highlight the features of the conceptual apparatus of historical science in Ukraine in the light of modern methodological searches, one of the essential aspects of which is the question of the specificity and potential of scientific knowledge. In particular, the efforts and achievements of Ukrainian scientists in the study and understanding of the process of formation of the conceptual apparatus of historical science in Ukraine are highlighted. They characterized both «weaknesses» and achievements in the scientific activity of domestic historians-scientists in the field of developing the terminology system of their studies, traced the reasons for the lack of unity among them regarding several topical issues, first of all, the specifics of historical knowledge, as well as outlined the urgency and promising ways overcoming these problems at different theoretical and methodological levels. The opinion is substantiated that the definition of key concepts of historical science and their proper rethinking, coordination, unification, and redefinition according to the needs of time and the development of world science is essential for a professional historian. At the same time, it is shown that historical science, not only on the territory of Ukraine but also in the world in general, largely did not accept the achievements of science in the field of logic and renewal of the foundations of cognitive activity, perception of the world as a system, etc. The necessity of rethinking its foundations by modern historical science is revealed in connection with revolutionary changes in modern science and technology development, which forms the prerequisites for another cognitive turn. n this context, the definition of the concept of «history,» which is central for historians, as well as the related concepts of «historical fact,» «historical regularity,» «methodological canon,» etc., needs to be rethought by Ukrainian historians.

Bank Responsibility for Coverage Rights Auction Objects That Cannot be Controlled by the Auction Winner

Article entitled Bank Responsibility for Objects of Mortgage Auctions That Cannot Be Controlled by the Auction Winners. The transaction process for the transfer of land and building rights through an auction is quite easy and simple. As long as the parties involved fulfill their respective rights and obligations in accordance with the provisions of the applicable laws and regulations. Based on the explanation of Article 20 paragraph (1) of Minister of Finance Regulation Number 213/06.PMK/2020 regarding instructions for implementing auctions, auctions must run efficiently, effectively and provide legal certainty. This study aims to develop knowledge regarding bank responsibilities and legal protection for buyers of goods who are unable to exercise control over the object of the mortgage execution auction object. The form of research used in this research is normative, which is researched on legal principles, which are carried out on positive laws made in writing. The conclusion of this study: The bank is fully responsible for the juridical and physical leveraging of the auction object to the auction winner, based on Article 17 of the 2016 Auction Guidelines and Article 13 of the 2020 Auction Guidelines stating that the Seller, in this case Bank X, is responsible for the delivery of movable objects and/or immovable objects. Because basically, the law has regulated that the seller is obliged to guarantee the possession of the goods being sold safely and securely to the buyer. This form of accountability can be in the form of providing mediation so that the debtor wants to vacate the auction object voluntarily or by providing proper direction and coordination to the buyer to apply for an emptying execution or if as a last option, namely by returning payment of the auction price paid by the auction buyer. So that in the future the bank can facilitate the levering process and participate in guaranteeing the mastery of the collateral to hand over the auction object as a form of accountability, it is necessary to make a statement stating that if the debtor defaults, the debtor is obliged to voluntarily vacate the land and building of the mortgage, so that in the future the bank can obtain convenience in handing over the auction object and is also free from claims for compensation filed by the buyer.

Structure of a 10-23 deoxyribozyme exhibiting a homodimer conformation

Deoxyribozymes (DNAzymes) are in vitro evolved DNA sequences capable of catalyzing chemical reactions. The RNA-cleaving 10-23 DNAzyme was the first DNAzyme to be evolved and possesses clinical and biotechnical applications as a biosensor and a knockdown agent. DNAzymes do not require the recruitment of other components to cleave RNA and can turnover, thus they have a distinct advantage over other knockdown methods (siRNA, CRISPR, morpholinos). Despite this, a lack of structural and mechanistic information has hindered the optimization and application of the 10-23 DNAzyme. Here, we report a 2.7 Å crystal structure of the RNA-cleaving 10-23 DNAzyme in a homodimer conformation. Although proper coordination of the DNAzyme to substrate is observed along with intriguing patterns of bound magnesium ions, the dimer conformation likely does not capture the true catalytic form of the 10-23 DNAzyme.

An auto-tuned droop coefficient-based controller for microgrid system to enhance grid resilience during blackouts

This paper presents a reliable auto-tuned droop coefficient-based controller (ATDC) for a microgrid (MG) system for enhancing grid resilience during blackouts. Existing power system networks experience blackouts due to inevitable failures such as overloading on lines, failure of a protection system, and imbalance in the power lines. The consequences of blackouts can be resolved by adapting to the concept of resilient MGs with high dynamic stability for power restoration. However, impedance parameters of power lines will change during blackouts, this eventually affects system's performance. Therefore, synchronization of MG sources to the utility grid and providing power supply to the critical loads during power system blackouts are the key factors to be resolved by maintaining system within permissible limits. The proposed ATDC-based controller adapts to changes in system parameters and auto-tunes the droop coefficients to provide proper control coordination between the each of distributed generator (DG) in MG. The proposed ATDC-based controller is designed in silico, and its effectiveness is tested under various conditions of MG operations. Results are compared with conventional and improved droop controller strategies. The test results demonstrate that the proposed controller maintains grid supply frequency within IEEE-1547 standards while ensuring appropriate power-sharing between load and MG sources.

Pentecostalism and the Dynamics of Democratic Governance in Nigeria since 1999

The phenomenon of religious politics in Nigeria is an obvious one. In political aspects such as the style of governance, policy formulations and the electoral process in Nigeria, religion has been a decisive determining factor. However, the influence of Christian religion on politics in Nigeria could be both positive and negative. In other words, as religion enhances national development, it could also be counterproductive. This paper critically discusses the influence of Pentecostalism and the dynamics of the Democratic Government in Nigeria since 1999, emphasizing the roles of the church in political leadership in the country. In practicing politics in Nigeria, adherence to religious and moral values and observance of the Nigerian constitution, which provides freedom of religion, is necessary for national development. The study discovered that the uncertainty concerning the future of Nigeria is unfortunately connected to a poor democratic culture, which is an essential factor in the political life of every nation. The paper concludes that, despite the abundant economic resources and several attempts by different governments over the years to reduce poverty and unemployment and promote sustainable development, Nigeria is still struggling in many fronts due to lack of political will, corruption, and no proper coordination for sustainable growth and development programs, In addition, the church, even though a strong voice in the political system of the nation, has not played her roles well. It is argued that Christians need to get more actively involved in politics, and that the Christian religion can and should be an agent of change and progressive national development in Nigeria.

Anaesthetic Management of a Case of Down Syndrome with Chronic Kidney Disease Undergoing Major Orthopaedic Surgery

Background: Down syndrome is one of the common congenital chromosomal disorders. Renal complications in Down syndrome patients are rare but is increasing in number due to increased survival. Anaesthesia in such patients is challenging due to intellectual disability, anatomical complications and multiple comorbidities. Case: This case report describes the pre-operative evaluation and anaesthetic management of a 19 -year-old male patient with Down syndrome with hypothyroidism with Chronic Kidney Disease stage 4 who underwent open reduction internal fixation with plating for bilateral subtrochanteric fracture under general anaesthesia. It was a complicated surgery for both surgeon and anaesthetist because the patient was anaemic with significant anticipated blood loss along with fluid restriction during the perioperative period. We had major challenges like patient positioning, significant blood loss, hypotension, and early fluid overload. But an extensive preoperative evaluation, optimization prior and proper coordination we overcame the challenges. Conclusion: Major orthopaedic surgeries in patients like Down syndrome with chronic kidney disease create a major anaesthetic challenge due to expected significant blood loss, chances of fluid overload, multiple comorbidities and intellectual disability. Thorough preoperative evaluation, intraoperative monitoring as well as postoperative period is important as several complications are envisaged. So a closed group management with orthopaedic surgeon, nephrologist, anaesthesiologist, endocrinologist, nursing team is required to handle such complicated cases.

Optimal coordination of directional overcurrent relays and distance relays using different optimization algorithms

The focus of this study is on solving the coordination problem between distance relays (DISRs) and directional overcurrent relays (DOCRs), which is a complex nonlinear problem with various constraints. Ensuring proper coordination between DOCRs and distance relays is critical for maintaining the security of electrical networks. The primary objective of employing optimization algorithms is to determine the optimal operating time for zone-2 of distance relays, as well as the DOCRs setting, time dial setting (TDS), and pickup current (Ipickup). The optimization techniques must also guarantee that the primary and backup relays operate in sequence without any violation. To this end, both recent and well-established optimization algorithms are evaluated using an 8-bus network, with the aim of determining the DOCRs setting and the optimal operating time for zone-2 of distance relays. Furthermore, a comparative analysis of different optimization algorithms, including both traditional and recent techniques, is conducted.

The aim of this paper was to evaluate traffic flow deviations in connection with the continuation of the third wave of the COVID-19 pandemic.

SENTIMENTS OF TEACHERS IN THE IMPLEMENTATION OF CHILD PROTECTION POLICY: A PHENOMENOLOGICAL STUDY

This study aimed to explore the sentiments of teachers in the implementation of child protection policy. The researcher used a phenomenological approach method in qualitative research employing 12 teachers from one of the public schools in Davao City, of which six of them were identified for an In-Depth Interview and six for a Focus Group Discussion, with the aid of a semi-structured interview guide. The findings of the thematic analysis of the interview transcription revealed that teachers lack a deep understanding of the policy; there is a tendency for students to abuse the policy; and teachers demand for policy amendments. In addressing such sentiments, it was noted that teachers should observe proper monitoring and coordination, embrace effective strategy to address possible students abuse of the policy, and address teachers collective sentiments. It was then learned that the insights of teachers in the implementation of child protection policy include being accountable when difficult situations occur; realizing the importance of sharing good values with students, realizing the importance of establishing positive relationships with students and parents; and leading a child centered and policy-based institution. Overall, it is recommended that child protection policies be revisited with the support of DepEd to make recommendations for possible inclusions of protection and rights of teachers to due process in the policy and that schools are encouraged to participate in policy decision-making and implementation and building positive relationships with parents and learners. KEYWORDS: Child protection policy, positive relationships, rights of teachers, decision-making, monitoring and coordination

Research on the coordinated development of cross-border e-commerce and logistics under the background of big data

Abstract Cross-border electronic platform trade is an important embodiment of the digitalization of international trade, with much attention and response to national policies. This is a global business activity in which traders from different countries negotiate and conclude deals online, and the flow of goods is realized through international transportation. Taking the effectiveness of the coordinated development of cross-border trade and international transportation as the direction of exploration, we study the development mechanism of the harmonious, proper coordination, and virtuous cycle of both from the digital background. According to the established model assumptions, based on the principles of science, objectivity, operability, and representativeness, the evaluation system of coordinated development level is constructed, and the subsystem sequential covariate efficacy function and the composite system coordination degree are calculated. From the results of correlation and coordination degree analysis, it shows that the total volume of transactions in this form of trade grows from $1.4 trillion in 2013 to $8.7 trillion in 2020, with an average annual growth rate of 32%. The orderliness of the cross-border logistics subsystem keeps increasing between 2013 and 2020, and the growth rate reached an average of 15.84 %/year. On the whole, the orderliness of each of the two subsystems steadily increases year by year. The resulting coordinated development trend of electronic trade between countries and international transportation coincides with the electronic trade between countries stepping into a brand-new development period, which is sufficient to verify the science and reasonableness of the evaluation system.

A new methodology for optimization of overcurrent protection relays in active distribution networks regarding thermal stress curves

In this paper, a novel method for optimizing and coordinating directional overcurrent relays in active distribution networks considering thermal equivalent short-circuit current is proposed. A modified genetic algorithm is used as a tool in order to simultaneously minimize the operating times of the primary relays and maximize the time delay between the operation of backup relays and their respective protected elements’ thermal stress curves. In other words, the objective function to be minimized is defined as the sum of the operating times of all primary relays and the reciprocal sum of the thermal violation check. The latter part is necessary because a protection engineer needs to be sure that the operation of a backup relay is as far as possible from the thermal stress curve of the protected element. Needless to say, for every solution, the algorithm ensures the proper coordination between primary and backup relay pairs throughout the network. The simulation is carried out for a closed loop medium voltage distribution network and the results are presented to demonstrate the effectiveness of the proposed approach. The main benefit of this optimization process is that it indicates whether the existing protection system can operate safely below the thermal stress curves of the protected elements’ or whether additional measures are required.

A bi-level optimization method for voltage control in distribution networks using batteries and smart inverters with high wind and photovoltaic penetrations

In electrical distribution systems, the voltage quality problem considers the most restrictive issue that hinders high photovoltaic (PV) and wind integration. Therefore, this study aims at providing a reliable control method for the voltage problem in distribution networks embedded with high PV and wind sources. The proposed voltage management strategy consists of two controlling stages. The first stage uses battery energy storage systems (BESS), while the second stage employs the smart PV inverters' reactive power injection capability. For BESS operation, a bi-level optimization method based on metaheuristic optimization algorithms (MOA) is developed to regulate the voltage levels by governing the batteries charging/discharging rates. The bi-level optimization problem aims to maximize PV and wind energy exploitation while improving the voltage profile. In this study, a detailed comparison is conducted between three MOA: Social Spider Optimization, Particle Swarm Optimization, and Cuckoo Search Optimization. In addition, considering the uncertainty associated with PV system generation, a PV generation forecast is embedded in the voltage control strategy to reinforce the decision-making process of BESS operation. The efficacy of the proposed method is deployed on a modified IEEE-34 bus test feeder with real-world load and PV and wind power generation data. Experimental results show the effectiveness of the proposed method and indicate that proper coordination between the BESS and smart PV inverters is beneficial for distribution system operations that seamlessly integrate PV and wind energy. Overall, the proposed voltage management strategy can be used to control the voltage to any desired range at different locations.

Evidence-informed Mental Health and Psychosocial Support (MHPSS) Guidelines: Are They Any Good and Where DoThey Lead Us When Disaster Strikes?

Introduction:Disasters and humanitarian crises can have a tremendous impact on the mental health and psychosocial well-being of affected populations. Reliable and practical evidence-informed mental health and psychosocial support (MHPSS) guidelines are indispensable for policy and practice to address the mental health impact. Our objective was to review the quality of available guidelines and to explore similarities and differences in content.Method:The review was conducted in two steps. Firstly, MHPSS guidelines, frameworks, manuals and toolkits were selected via a systematic literature review as well as a search in the grey literature. A total of 13 MHPSS guidelines were assessed independently by 3–5 raters using the Appraisal of Guidelines for Research and Evaluation–Health Systems (AGREE-HS) instrument. Secondly, we analyzed the content of the highest-ranking guidelines.Results:Guideline quality scores varied substantially, ranging between 21.3 and 67.6 (range 0–100, M= 45.4), with four guidelines scoring above midpoint (50). Overall, guidelines scored highest (on a 1–7 scale) on topic (M = 5.3) and recommendations (M = 4.2), while implementability (M = 2.7) is arguably the area where most of the progress is to be made. The four guidelines proved largely similar, overlapping or at least complementary in their MHPSS definitions, stated purpose of the guidelines, user and target groups, terminology, and models used. Many recommended MHPSS measures and interventions were found in all of the guidelines and could be categorized. The guidelines stress the importance of monitoring needs and problems, evaluating the effect of service delivery, deliberate implementation and preparation, and investments in proper conditions and effective coordination across professions, agencies, and sectors.Conclusion:The MHPSS knowledge base embedded in guidelines is rich and contains invaluable content for disaster risk reduction. Although application contexts differ geographically, available guidelines should allow policymakers and practitioners globally to plan, implement, and evaluate MHPSS actions.

WHO Health EDRM Research Network and Health Data Management

Introduction:The WHO Health Emergency and Disaster Risk Management (H-EDRM) Research Network has identified that health data collection during health emergencies and disasters is a key element to enable proper coordination and timely response, and research priorities of the network.Method:Focus group discussion was performed to identify key challenges which hinder accomplishment of the data collection.Results:It was concluded that the issue faces significant challenges including; (1) Access: Logistic issues including safety, transport and communication did not allow experts such as epidemiologists to access onsite and relevant stakeholders. It is also challenging for local public health stakeholders to accept new experts during emergencies. (2) Tools: forms or tools that are concise and operational to be accepted by frontline responders should be provided. (3) Standardization: to set standard forms or tools and its operational mechanism is essential to collect health data, otherwise collected data will be partial and fragmented. (4) Governance: overall governance of procedure and data ownership must be clarified before its implication administratively and legally. These should be endorsed by local health authorities. (5) Ethical procedure: Obtaining informed consent and conducting timely procedures is difficult. Contextually, health data collection during emergencies and disasters in many cases is inappropriate. (6) Operation: Collected data should contribute to ongoing operation in a timely manner. The discussion also found the standard tool of the WHO; the Emergency Medical Teams Minimum Data Set, which has been already used in more than ten countries and has been providing leading examples for this topic.Conclusion:Further research to fulfill the identified challenges and gaps will facilitate the collection and strengthen the health emergency and disaster risk management.
