Augmenting rooftop solar energy penetration ratio with secondary distribution network using smart inverter for maximum power transfer capacity for subordinate grid- A review

ABSTRACT A rooftop photovoltaic power station, or rooftop PV system, is a photovoltaic system that has its electricity-generating solar panels mounted on the rooftop of a residential or commercial building or structure. The various components of such a system include photovoltaic modules, mounting systems, cables, solar inverters, and other electrical accessories. Rooftop mounted systems are small compared to ground-mounted photovoltaic power stations with capacities in the MW (megawatt) range. With the significant improvement of Rooftop Solar Photovoltaic Energy System (RSPES) among various Renewable Energy Systems, the major issues, effects, and several operational characteristics of the rooftop solar PVs in the Distribution System (DS) with Low Power Utility Network are actively being studied and investigated by global researchers and operation engineers. The most important objective of various researches about RSPES is to design a Power System with Optimal Maximum Power Transfer Capacity (MPTC). These review papers analyze the performance of Secondary Distribution System integrated to grid with Smart Inverter with or without the presence of Distribution Generation (DG) units. The effects caused by the penetration of Rooftop Solar Photovoltaic (PV) units in the Distribution Equipment (DE) are detailed in this paper with various research techniques. With the consideration of different objective constraints, Optimization techniques are utilized for solving minimization problems of objectives such as Size, Area, Operational Characteristics, Energy Loss, Cost of Installation, Generation Cost, Peak Load, Reverse Power Flow, and maximization problems of objectives such as PV power generation, Energy Saving Capability, Electricity Energy Mix, etc. The various optimization techniques and frameworks for improving the performance of Power System and their corresponding results are demonstrated in this paper. This paper reviews totally 42 related researches done on the different phases of Optimization based Rooftop Solar PV system in the period between 2015 and 2017. This review summarizes the evaluation of the i) Solar rooftop energy with effects of increase in penetration; ii) The performance of efficient secondary distribution system with grid integrated smart inverter; iii) Algorithms based on optimization for solving the objectives in rooftop solar PV system are investigated.
Fructose Metabolism and Exercise: Physiological Applications and Limitations

Fructose has gained renewed interest for its suspected role in cardiometabolic diseases and as a performance enhancer in sports nutrition. Both are related to fructose metabolism in the liver resulting in no plasma glucose or insulin peaks, but causing postprandial hyperlactatemia and hypertriglyceridemia. The general aim of this work was to further investigate fructose metabolism and to find potential new applications of fructose that may improve performance. In a first experimental study, we evaluated how fructose metabolism is modulated by an exercise session performed before or after fructose ingestion. Although confirming that fructose is extensively oxidized during exercise, our results also showed that fructose metabolism was largely unaltered when ingested during recovery. In a second study, we used fructose in mixed-meals provided for 24 h postexercise to specifically favor muscle energy storage and subsequent exercise performance. Compared to an isocaloric control, fructose did however not further improve muscle recovery, and fructose impaired whole-body glycogen storage and subsequent exercise performance. In a third study, we investigated the effects of glucose-fructose ingestion during training sessions on lactate metabolism, at rest and during exercise, pre-training and post-training. Interestingly, training with glucose-fructose increased lactate production, consumption and oxidation at rest but not during exercise, and an important part of lactate was directed to non-oxidative fates in all conditions. Altogether, the present results indicate an ambivalent role of fructose, efficient to fuel muscle work, but inefficient during postexercise recovery. This may be largely due to fructose conversion into lactate, furnishing an alternative fuel during exercise that however needs to be stored for an extra energy cost in resting times. In turn, this “reverse Cori cycle” may represent an important mechanism by which fructose effects are matched to physical activity.
Optimized Design of Cold‐Formed Steel Elements for Serviceability and Ultimate Limit States

Cold‐formed steel (CFS) sections are gaining ever increasing popularity in modern construction practice due to their advantages, such as efficient material use and sustainability. While the manufacturing flexibility of CFS cross‐sectional shapes brings innovative and complex shapes within practical reach, obtaining optimum design solutions can be a challenging task due to the complex mechanical behaviour of CFS elements, which is controlled by local, distortional and global buckling modes, as well as the need to account for manufacturing and end‐use constraints. This study presents a practical framework for the development of optimised CFS beam sections with maximum flexural strength and minimum deflections in ultimate and serviceability limit state conditions, respectively, in accordance with Eurocode 3 (EC3). A population‐based Genetic Algorithm optimisation method is employed to obtain optimum solutions for ten different CFS cross‐section prototypes, while the EC3 geometric restrictions and a number of manufacturing and end‐use constrains are also considered. It is shown that sections optimised based on serviceability limit state (SLS) and ultimate limit state (ULS) requirements can provide up to 44% higher effective stiffness and 55% higher bending moment capacity, respectively, compared to standard commercial lipped channel sections with the same amount of material. The results also indicate that using optimised plain channels and folded‐flange sections generally leads to the best design solution in SLS and ULS optimization, respectively.
“She Took Care of Us and She Went Through a Lot”: Emotional Availability, Emotional Support, and Millennials’ Gendered Understandings of Parenting

In the United States, parenting pressures are growing for both mothers and fathers. Thus, it is important to investigate how younger generations may make sense of parenting in ways that could either reduce, or exacerbate, gender inequalities. In this article, interviews with 60 millennials discussing their experiences with their parents reveal that emotional support and emotional availability are key normative parenting expectations. However, disparate gender norms also factor into millennials’ stories about their parents’ efforts. These millennials often criticize fathers for sometimes being too absent, authoritarian, or ego-driven while they understand mothers as constrained by fathers’ bad behaviors yet still bound by expectations to be emotionally available and supportive in appropriately gendered ways. In millennials’ stories, emotional support and availability are seemingly gender neutral and millennials expect both fathers and mothers to live up to these expectations. However, broader structural gender norms challenge the apparent neutrality of parenting expectations.
Analytical and Numerical Evaluation of Co-Scheduling Strategies and Their Application

Applications in high-performance computing (HPC) may not use all available computational resources, leaving some of them underutilized. By co-scheduling, i.e., running more than one application on the same computational node, it is possible to improve resource utilization and overall throughput. Some applications may have conflicting requirements on resources and co-scheduling may cause performance degradation, so it is important to take it into account in scheduling decisions. In this paper, we formalize the co-scheduling problem and propose multiple scheduling strategies to solve it: an optimal strategy, an online strategy and heuristic strategies. These strategies vary in terms of the optimality of the solution they produce and a priori information about the system they require. We show theoretically that the online strategy provides schedules with a competitive ratio that has a constant upper limit. This allows us to solve the co-scheduling problem using heuristic strategies that approximate this online strategy. Numerical simulations show how heuristic strategies compare to the optimal strategy for different input systems. We propose a method for measuring input parameters of the model in practice and evaluate this method on HPC benchmark applications. We show the high accuracy of the measurement method, which allows us to apply the proposed scheduling strategies in the scheduler implementation.
Antibacterial Properties of PLGA Electrospun Scaffolds Containing Ciprofloxacin Incorporated by Blending or Physisorption.

Electrospun fibers are excellent candidates for wound dressings and tissue engineering scaffolds. To actively prevent infection during wound healing, the electrospun fibers can be loaded with antimicrobial agents, such as antibiotics or natural antimicrobials. Different methods have been used to incorporate antimicrobial agents in electrospun fibers during the electrospinning process, including blending, coaxial electrospinning, and emulsion electrospinning, to provide controlled release of the agent. Some evidence suggests that a burst release of antimicrobials through physical adsorption, or physisorption, may offer improved antibacterial properties, but a comparison between physisorbed and blended antimicrobial agents has not been conducted. In this study, the antimicrobial and release properties of poly(lactide-co-glycolide) electrospun fibers containing either blended or physisorbed ciprofloxacin are compared using disks containing similar initial amounts of ciprofloxacin. The results demonstrate that physically adsorbed ciprofloxacin provides more effective antibacterial properties than blended ciprofloxacin up to 48 h against P. aeruginosa PA14, S. aureus, and S. epidermidis regardless of initial loading due to a faster release of the antibiotic in the first 6 h. However, beyond 24 h, blended ciprofloxacin retained the clear zones better than physisorbed ciprofloxacin due to a continuous release. Physisorption offers a simple approach for incorporating antibiotics in electrospun fibers for stronger short-term antibacterial effects and may be applied to scaffolds containing blended antibiotics to sustain antibacterial properties for long-term wound dressings.

Connecting Mobile Application Features with Perceived Benefits in Determining Post-adoption Behaviour

This study aims to identify the perception of users, regarding characteristics of retail mobile applications (apps) on perceived benefits and their impact on post-adoption behaviour. On 264 useful responses, exploratory factor analysis, confirmatory factor analysis and structural equation model were applied via using SPSS 22 and Amos 22. The results showed that mobile app features, that is, perceived ubiquity, perceived informativeness, perceived personalization and perceived entertainment significantly impact mobile app usefulness and playful engagement. Only perceived informativeness has an insignificant impact on playful engagement. Both mobile app usefulness and playful engagement have a significant impact on mobile app stickiness, whereas they do not have any impact on mobile app word of mouth (WOM). Mobile stickiness also has a significant impact on mobile app WOM. This study highlights the post-adoption behaviour of the consumer towards retail mobile apps and expands practical knowledge of consumers’ behaviour towards using retail mobile apps.
UTILIZATION OF MULTITEMPORAL LANDSAT DATA FOR COASTLINE CHANGE ANALYSIS USING CANNY EDGE DETECTOR

ABSTRACT The development of remote sensing technology has experienced significant progress. This progress is marked by the availability of images of various resolutions with complete channels, open-source, and their development in various image classification techniques such as edge detection techniques. This study aims to examine changes in the coastline in Banmaleng Village, Gili Raja Island, Sumenep Regency using the Canny edge detection algorithm on multitemporal Landsat 7 and 8 imagery in 2005 - 2020. The edging process includes (a) minimize noise by applying a Gaussian filter, (b) determine the image intensity gradient, (c) apply non-maximum emphasis to eliminate spurious responses to objects, (d) define multiple thresholds for determining potential image edges, (e) Track edge hysteresis by pressing all other weak edges that are not connected to firm edges. Canny edge detection produces sharp edges to analyze coast line changes quite well. Every five years, the coastline of Banmaleng Village experienced shifting from 0 , 4 to 2 , 3 meters in several areas. Keywords : Edge Detection, Landsat, Coastline, Canny Algorithm, Gili Raja
A new multivariate control chart for monitoring the quality of a process with the aid of auxiliary information

Control chart is a statistical process control tool to routinely monitor the quality of a process. In the past decade, using auxiliary information to enhance the ability of control chart to detect parameter shifts has attracted wide attention in literature. Most of the existing works in this topic use a linear model and assume performance and auxiliary variables follow a bivariate normal distribution to establish the auxiliary-information-based (AIB) charts. However, the normality assumption could be violated on some occasions. In this study, the skew-normal distribution is used to characterize the auxiliary variable to expand the joint distribution of the performance and auxiliary variables to a generalized joint family. Then, a new multivariate AIB chart is established to monitor the quality of process. The performance of the proposed AIB control chart method is verified using Monte Carlo simulations. An example with regard to the cement filling process is used for illustration.
Genetic Diversity of Dacrycarpus imbricatus At Bukit Tapak, Tabanan, Bali Based on RAPD Marker

Dacrycarpus imbricatus Blume is a member of the Podocarpaceae family. In Bali, D. imbricatus was found in Bukit Tapak, Tabanan Regency. This species is one of the dominant species in Bukit Tapak. This study aimed to determine the genetic variation of D. imbricatus in Bukit Tapak using molecular markers RAPD (Random Amplified Polymorphic DNA). The genetic diversity of D. imbricatus needs to be studied to obtain the information used for the conservation of this species. Leaf samples were taken from Bukit Tapak, Candikuning, Baturiti, Tabanan Regency, Bali. DNA was extracted using the CTAB method, followed by extraction using chloroform: isoamyl alcohol. DNA precipitation was carried out using ethanol. RAPD analysis was performed using polymerase chain reaction (PCR) using four primers. PCR products were visualized using agarose gel electrophoresis and ethidium bromide staining. The results showed that the amplified DNA bands ranged from 1 to 5 bands with DNA band sizes ranging from 230 bp - 422 bp. Only OPA4 and UBC106 primers can be used to detect D. imbricatus diversity based on the H, D, and R values. The detected genetic variation is low, as indicated by an average polymorphism of 32.5% and similarities between samples ranging from 0.51 to 1
Concept of research literacy in academic continuing education: a systematic review

To date, research literacy has not been studied conceptually in academic continuing education even though it has gained recognition in practice as one of competence areas that learners need to acquire. The aim of our review was to identify the concepts and competences related to research literacy in academic continuing education in order to provide a fit concept of research literacy in academic continuing education. We roughly followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement. We conducted the search in the domains of continuing education and higher education, in case of lack of research in continuing education. Our search identified in total 857 items. Based on title and abstract review, we considered 111 articles for review. After scrutinising the full-text articles, we included 72 publications for the extraction of the data and analysis. The main finding of the review is the lack of research on research literacy in continuing education. Our search did not yield any study that focused on academic continuing education. A second important finding is the lack of a comprehensive and holistic concept of research literacy, not only for continuing education, but also for higher education. Especially with the global trends and changes altering ways of production and research, it is important to provide an up to date definition of research literacy and the right set of skills and competences that meet the needs of learners in academic continuing education.
Motivational Antecedents, Value Co-Creation Process, and Behavioral Consequences in Participatory Sport Tourism

This study was designed to examine the structural relationships among tourists’ participation motivations, the value co-creation process (VCCP), and value co-creation behavior (VCCB) in terms of in-role and extra-role contributions. Based on a comprehensive review of literature, participation motivations were measured with four constructs, including need for uniqueness, need for self-control, need for social interaction, and need for leisure and entertainment. Research participants (N = 445) who had participated in two or more marathon events in China were recruited to respond to an on-site or online survey. Conducting structural equation modeling analyses, three motivational factors of need for uniqueness, need for social interaction, and need for leisure and entertainment were found to exert significant (p < 0.05) and positive impact on VCCP, which in turn had significant (p < 0.05) influence on in-role and extra-role contributions associated with VCCB. Discussions are centered on promoting specific areas of participants’ motivations in an effort to empower and energize the process of value co-creation and to ultimately activate and sustain participants’ in-role and extra-role behaviors.
Ferromagnet-antiferromagnet transition in layered perovskites of Sr3YCo4O10.5 type

Sr1−xYxCoO2.65 (x = 0.2) with layered perovskite structure was studied by neutron diffraction, synchrotron x-ray and magnetometry methods. It is shown that in the 90–375 K temperature range the crystal structure can be described by the monoclinic space group A2/m with the superstructure 4√2ap × 2√2ap × 4ap (with ap corresponding to the unit cell parameter of the primitive cell) while basic diffraction peaks are well indexed in the space group I4/mmm (2ap × 2ap × 4ap) shows an almost standard magnetization. The basic magnetic structure is G-type antiferromagnetic with average magnetic moments of 2.7 μB/Co and 1.7 μB/Co in anion-deficient CoO4+γ and stoichiometric CoO6 layers, respectively. A ferromagnetic component of about 0.27 μB/Co is determined from the magnetization measurements at 8 K. Sr0.8Y0.2CoO2.65 shows an almost standard magnetization versus temperature dependence whereas Sr0.75Y0.25CoO2.65 exhibits an antiferromagnet-ferromagnet transition accompanied by a structural transformation. There is practically no spontaneous magnetization in x = 0.3. The type of the magnetic structure and the high value of TN suggest that the Co3+ ions are in both structural layers predominantly in the low-spin (LS)/high-spin (HS) state mixture. It is proposed that the ferromagnetic component is due to the orbital ordering occurring at TN in the CoO5 pyramids and the concomitant appearance of ferromagnetic coupling between the Co3+(HS) ions located in these CoO5 pyramids in the anion-deficient CoO4+γ layer.
Advanced Flexibility Market for System Services Based on TSO–DSO Coordination and Usage of Distributed Resources

The high and growing share of renewable sources and the more important role of Distributed Energy Resources (DERs) in the Distribution System (DS) is leading to a need for more efficient coordination of those sources. In future power systems, TSO–DSO coordination will play a key role in providing flexibility services. Lack of proper coordination of sources may lead to congestion in the network or to a lack of possibility to generate or consume energy on a requested level. The crucial aspect is that the TSO–DSO coordination must be based on an active role of all participants: TSO, DSO, generation units and the demand. This paper presents the possible application of the TSO–DSO coordination by providing the flexibility services from DS to the Transmission System (TS). The paper presents the complex optimization of TS, DS and its coordination. The main goal of the paper is to show the possibility of the application of the flexibility market into the current system design. It requires the creation of a new platform, where the offers of the flexibility services could be submitted and then exchanged between entities. The paper shows that the usage of flexibility services may decrease the operational cost of the system, and the DERs providing those services may benefit from an additional source of income.
