This paper provides an overview of islanding fault detection in microgrids. Islanding fault is a condition in which the microgrid gets disconnected from the microgrid unintentionally due to any fault in the utility grid. This paper surveys the extensive literature concerning the development of islanding fault detection techniques which can be classified into remote and local techniques, where the local techniques can be further classified as passive, active, and hybrid.

AbstractTemporal networks have been successfully applied to analyse dynamics of networks. In this paper we focus on an approach recently introduced to identify dense subgraphs in a temporal network and we present a heuristic, based on the local search technique, for the problem. The experimental results we present on synthetic and real-world datasets show that our heuristic provides mostly better solutions (denser solutions) and that the heuristic is fast (comparable with the fastest method indoi:10.1007/s42979-021-00593-w fatcat:co2srsnlp5eoxibvkox67lm6ny

This paper proposes a traffic control scheme to alleviate traffic congestion in a network of interconnected signaled lanes/roads. The proposed scheme is emergency vehicle-centered, meaning that it provides an efficient and timely routing for emergency vehicles. In the proposed scheme, model predictive control is utilized to control inlet traffic flows by means of network gates, as well as configuration of traffic lights across the network. Two schemes are considered in this paper: i)arXiv:2204.05405v1 fatcat:3uto3tmqwrfcvjzeuwkimn2ene

This scheme provides the optimal solution, even though it might not fulfil real-time computation requirements for large networks. In the decentralized scheme, each intersection has its own control unit, which sends local information to an aggregator. The main responsibility of this aggregator is to receive local information from all control units across the network as well as the emergency vehicle, to augment the received information, and to share it with the control units. Since the decision-making in decentralized scheme is local and the aggregator should fulfil the above-mentioned tasks during a traffic cycle which takes a long period of time, the decentralized scheme is suitable for large networks, even though it may provide a sub-optimal solution. Extensive simulation studies are carried out to validate the proposed schemes, and assess their performance. Notably, the obtained results reveal that traveling times of emergency vehicles can be reduced up to ~50% by using the centralized scheme and up to ~30% by using the decentralized scheme, without causing congestion in other lanes.

Chlamydia trachomatis is considered as an important cause of preventable sexually transmitted diseases worldwide. It is known to be of an obligate intracellular nature and enters its target cells via an endocytic process. As major outer membrane protein (MOMP) is one of the main candidates for the attachment and entry of chlamydia to the host cells we have tried to label the epitopes by using different techniques. Materials and methods McCoy cells were experimentally inoculated with 104doi:10.22074/ijfs.2009.45785 doaj:e94639915da5489a8bf0652cb59aca26 fatcat:pyxbzcersretdj5inbrrspoobq

The infected cells were then processed for direct fluorescent antibody (DFA) and transmission electron microscopy (TEM) using anti- MOMP antibody and pre- and post-embedded labelling techniques. Results DFA was able to detect 11/11 (100%) of the infected cells. These values were recorded as 9/11 (81.81%) and 8/11 (72.72%) using pre- and post-embedded techniques respectively. Conclusion MOMP is proposed to be one of the most important adhesion molecules for chlamydial attachment and entry into host cells.

Progress in wireless communication has made possible the development of low cost wireless sensor networks. In recent years, as the development of wireless sensor networks, people have done some research on cluster-based protocol, about the proongation of the lifetime of WSN and decrease of energy consumed by the sensors. Clustering sensor nodes is an effective topology control approach, but these algorithms are not optimized for the characteristics of heterogeneous wireless sensor networks.doi:10.1109/iccsit.2010.5563781 fatcat:ptahe5xmzvbgxhs4zpzlxtffqq

In our protocol, NEAP (the Novel Energy Adaptive Protocol for heterogeneous wireless sensor networks) the cluster-head is elected by a probability, based on threshold per round and cluster formation based on nodes current battery power and numbers of members currently under a cluster-head are taken, distance between cluster-heads and nods. At last, the simulation results show that NEAP achieves longer lifespan and reduce energy consumption in wireless sensor networks.
In this study, for the first time, a novel strategy for the synthesis of graft copolymers using polystyrene (PSt) monomer from surface modification of poly(ethylene terephthalate) PET through surface-initiated nitroxide-mediated radical polymerization was performed. For this purpose, the PET surface was first aminated by 1,3-diamino propane, which was used as an amination agent. Second, phenyl chloro acetylation of PET was prepared by coupling amino and hydroxyl groups with α-phenyl chlorodoi:10.22063/poj.2022.3112.1211 doaj:cb21208d55f6433891605fcc00b60ca2 fatcat:ajt5blwxpjdyhkuncu2z4w2vzu

Afterward, 2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO) was synthesized, then 1-hydroxy-2,2,6,6-tetramethylpiperidine (TEMPO–OH) was obtained by reduction of TEMPO with sodium ascorbate and coupled with chloroacetylated PET to obtain PET-TEMPO macroinitiator. Furthermore, the (St) monomer was grafted onto the PET surfaces through the "grafting from" technique. The obtained macroinitiator for living radical polymerization was heated in the adjacency of (St) monomer to obtain the graft copolymer (PET-g-PSt) onto the PET surfaces. Finally, PET-g-PSt/MMt nanocomposite was synthesized by the solution intercalation method. The surface combination, morphology, and thermal properties of the modified PET films were proved using various characterization methods such as transform infrared spectroscopy (FT-IR), 1H nuclear magnetic resonance (1H NMR), differential scanning calorimetry (DSC), thermogravimetric analysis, X-ray photoelectron spectroscopy, and termination electron microscopy (TEM).
The evolution of networks is a fundamental topic in network analysis and mining. One of the approaches that has been recently considered in this field is the analysis of temporal networks, where relations between elements can change over time. A relevant problem in the analysis of temporal networks is the identification of cohesive or dense subgraphs since they are related to communities. In this contribution, we present a method based on genetic algorithms and on a greedy heuristic to identifydoi:10.1016/j.procs.2020.08.023 fatcat:o2mxso222bhzbopwqq4zpt3ug4

We present experimental results considering both synthetic and real-networks, and we analyze the performance of the proposed method when varying the size of the population and the number of generations. The experimental results show that our heuristic generally performs better in terms of quality of the solutions than the state-of-art method for this problem. On the other hand, the state-of-art method is faster, although comparable with our method, when the size of the population and the number of generations are limited to small values.
