Islanding Fault Detection in Microgrids—A Survey

Mehdi Hosseinzadeh, Farzad Rajaei Rajaei Salmasi
2020 Energies  
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. Various detection

Dense Sub-networks Discovery in Temporal Networks

Riccardo Dondi, Mohammad Mehdi Hosseinzadeh
2021 SN Computer Science  
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 in

MPC-Based Emergency Vehicle-Centered Multi-Intersection Traffic Control [article]

Mehdi Hosseinzadeh and Bruno Sinopoli and Ilya Kolmanovsky and Sanjoy Baruah
2022 arXiv   pre-print
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)

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.

Immuno-gold Labelling of Chlamydia trachomatis

Saeid Hosseinzadeh, Mehdi Fazeli
2009 International Journal of Fertility and Sterility  
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 104

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.

The Novel Energy Adaptive Protocol for heterogeneous wireless sensor networks

Mehdi Golsorkhtabar, Farzad Kaviani Nia, Mehdi Hosseinzadeh, Yones Vejdanparast
2010 2010 3rd International Conference on Computer Science and Information Technology  
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.

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.

Nitroxide mediated radical polymerization of styrene from poly(ethylene terephthalate) and its polymer/montmorillonite nanocomposite

2022 Polyolefins Journal  
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 chloro

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).

Genetic Algorithms for Finding Episodes in Temporal Networks

Mauro Castelli, Riccardo Dondi, Mohammad Mehdi Hosseinzadeh
2020 Procedia Computer Science  
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 identify

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.
