TL;DR: A deep learning-based intrusion detection system for the Internet of Things requires consideration of key design principles presented in this paper, and this paper focuses on the IDS implementation on the IoT network.
Abstract: In smart environments, comfort and efficiency are important goals in terms of the quality of human life. Recent developments in Internet of Things (IoT) technology have made it possible to design smart environments. IoT-based smart environments are concerned with security and privacy as key issues. Systems based on the IoT pose a security threat to smart environments. In order to prevent IoT-related security attacks which take advantage of some of these security vulnerabilities, intrusion detection systems (IDSs) designed for IoT environments are crucial. Data generated by connected objects in the age of the IoT provides the basis for big data analytics, which could be employed to identify patterns and identifies anomalies in data. In order to detect intrusions, most cyber security systems employ IDSs, which are used by a variety of techniques and architectures. As opposed to signature-based IDS, anomaly-based IDS learns the normal pattern of system behavior and alerts on abnormal events that occur, as opposed to monitoring monitored events against a database of known intrusion experiences. This paper focuses on the IDS implementation on the IoT network. The use of sensor devices to collect data from smart grid environments has led to smart grids becoming the preferred intrusion target due to the IoTs using advanced information technology. Clouds are data storage systems that provide a variety of smart infrastructure services, such as smart homes and smart buildings, over the internet. A deep learning-based intrusion detection system for the Internet of Things requires consideration of key design principles presented in this paper.

TL;DR: The background of climate change, and its corresponding impacts on the environment and every species on our planet is presented in this paper , which provides an overview and deep insights of some major reasons behind the evolution of this problem and illustrates some important steps taken towards the reduction of this extreme problem.
Abstract: In recent decades climate change has become a major threat for our planet due to anthropogenic global warming interconnecting with environmental and other social determinants, constituting an extreme risk of health for every life on earth. The ecology of the earth is facing very bad effects such as inappropriate timing of the monsoon, health risk to the human beings, increasing temperature of the earth, increasing water level of the ocean, missing of some small and even bigger species from ecology, and many more due to climate change. Some major reasons such as decrement in the number of trees and forests and huge emissions of greenhouse gases such as CO2 and chlorofluorocarbon (CFC) are the main factors of climate change. This paper is presented to demonstrate the background of climate change, and its corresponding impacts on the environment and every species on our planet. We cover a wide range of surveys of the research articles published on this issue in the last two decades. This article provides an overview and deep insights of some major reasons behind the evolution of this problem and as well as illustrates some important steps taken towards the reduction of this extreme problem.

TL;DR: A scheme that will reduce the number of flow entries of IPv6 packets using two multiprotocol label switching tags in Software Defined Networks and can be used by Internet Service Providers for real-time network flow that will provide handling of an unpredictable surge of big-data transmission across network backbone.
Abstract: Software-Defined Networking (SDN) is a technique that breaks the vertical integration of networks by separating the networks’ control logic from the underlying routers and switches that forward the traffic. The performance of SDN network nodes may be degraded due to flow entries that are frequently updated and stored in the network elements. The control plane is flooded by the configuration messages thereby resulting in a trade-off between the number of configuration messages and number of permanent flow entries in the network.The focus of the study is to develop a scheme that will reduce the number of flow entries of IPv6 packets using two multiprotocol label switching tags in Software Defined Networks. An experimental testbed was developed using openvswitch, Ryu controller, OpenFlow version 1.3, IPERF3 and Wireshark. A Mininet kernel was built on Ubuntu Linux 18.04.1 operating system. The IPv6 Hybrid Permanent Flow (HPF) scheme and Non-Permanent Flow (NPF) was used to reduce the number of permanent flow entries and the number of configuration messages from the controller to the Ternary Content Addressable Memory (TCAM) of the Openswitch.The Result shows that IPv6 HPF scheme had a reduction of 63% as against NPF in the network for the dependency of switch per region while 33% reduction in flow entries of the network for the dependency of host per switch. The result can be used by Internet Service Providers (ISPs) for real-time network flow that will provide handling of an unpredictable surge of big-data transmission across network backbone.

TL;DR: A collaborative ITS to teach UML is presented that is built to enable students to effectively communicate and share each other's mistakes and is capable of detecting and identifying student errors.
Abstract: Computer-based learning tools called Intelligent Tutoring Systems (ITS) assist students to become better learners by simulating human tutors using Artificial Intelligence (AI) approaches. Students can interact using collaborative ITSs from various locations to study, discuss, and articulate concepts relevant to a certain problem. This paper presents a collaborative ITS to teach UML that is built to enable students to effectively communicate and share each other's mistakes. The ITS is capable of detecting and identifying student errors and offers students suggestions during the problem-solving stage, giving them guidance on how to proceed. The ITS also determines a student's current level of thinking and intellect in order to assign them activities that need more attention. The evaluations conducted for this study revealed that the experimental group had considerably more learning gains (81% scores on the posttest) than the control group, where students only showed a very low significant change in their learning with posttest scores of 46%

TL;DR: In this paper , a response surface study was made with a central design composed of three replicates per point to obtain a surface equation that determines the expected roughness value based on the velocity values of cutting speed and fate rate.
Abstract: This research aims to determine the behavior of the surface roughness parameters Ra, Rq and Rz in the milling of poly-ether-ether-ketone PEEK, in terms of the machining variables: cutting speed feed rate and the machining strategy. To solve this problem, a response surface study was made with a central design composed of three replicates per point to obtain a surface equation that determines the expected roughness value based on the velocity values of Cutting speed and fate rate. This model was repeated for each machining strategy analyzed: Raster and Spiral. To find the correct values of Rq and Rzin, the manufacturer could find desirable values; it could be for minor friction pieces or better shape forms. This investigation found that the value of Rq and Rz in milling machining with a Raster and Spiral trajectory increases with increasing feed rate and decreasing with cutting speed. Likewise, it was observed that the Raster technique obtains higher roughness values than by Spiral.

TL;DR: In this paper , the steady-state performance of a DC motor fed by a non-isolated quadratic DC-DC boost converter was analyzed under a DC shunt motor of 5 HP power rating.
Abstract: This paper presents the analysis of steady-state performance of a DC motor fed by a non-isolated quadratic DC-DC boost converter. The proposed quadratic configuration based non-isolated high voltage gain DC-DC converter operating in continuous conduction mode employs one power switch and reduced number of diodes and passive components. Due to single power switch, the switching and conduction losses are reduced thereby improving the converter efficiency. A DC shunt motor of 5 HP power rating is used as load to the proposed converter. The proposed cost-effective converter-fed DC motor operating under no-load is simulated using MATLAB / SIMULINK tool. The steady-state performance characteristics, such as speed, torque, and armature current of the DC motor, are obtained for one particular value of duty ratio of the power switch. The results validate the superior performance of the suggested DC-DC converter-fed DC motor at moderate duty ratio.

TL;DR: Using effective and dependable machine learning approaches to discover trends and anticipate the onset of diabetes in humans would aid in the earlier detection and treatment of the illness.
Abstract: Kidney failure, heart failure, blindness, and stroke are all common complications of diabetes. When we consume, our bodies transform food into sugar or glucose. Our pancreas is meant to release insulin at that point. Insulin is a key that allows glucose to enter and be utilized for energy in our cells. The two most common types of diabetes are Type 1 and Type 2. If diabetes is detected early enough, it can be controlled. Using effective and dependable machine learning approaches to discover trends and anticipate the onset of diabetes in humans would aid in the earlier detection and treatment of the illness. Smoking, diet, stress, sleeping time, exercise, and other factors can help us to determine whether a person is prediabetic or diabetic. This study focuses on recent advances in machine learning that have a significant impact on diabetes detection and diagnosis.

TL;DR: In this article , the use of TiO2 and ZnO catalysts for removal of textile dyes was mainly focused, mainly focused on the synthesis of photo catalysts was done by sol-gel method.
Abstract: Advanced oxidation processes (AOPs) are widely used for the removal of recalcitrant organic constituents from industrial and municipal wastewater. This study mainly focused the use of TiO2 and ZnO catalysts for removal of textile dyes. Synthesis of TiO2 and ZnO photo catalysts was done by sol-gel method. These catalysts were used to obtain enhanced photo catalytic action and were coated on glass beads to improve the photo catalytic activity. The synthesized beads were examined using SEM, FTIR and XRD. Synthesized photocatalysts were examined extensively for their photocatalytic activities with Reactive Orange(RO), Reactive Blue(RB), Textile industry Effluent (TIE) and mixture of dyes (RO+RB, RO+RB +TIE) at various concentrations (50ppm, 100ppm). The photocatalytic degradation of RO, RB, TIE, RO+RB and RO+RB +TIE dyes solution (100mg/L and 50mg/L) using TiO2 and ZnO were investigated under UV light irradiation (λ=254nm). Photocatalytic studies revealed that the TiO2 has shown much higher photocatalytic activity than the ZnO catalyst. The photocatalytic activity of the TiO2 catalyst follows the order: Reactive Orange of 50 ppm (80.98%) > Reactive Blue dye of 50 ppm (77.17%)> Reactive Orange dye of 100 ppm (74.98)>Reactive blue of 100 ppm (72%). The photocatalytic activity of the ZnO catalyst follows the order: Reactive Orange of 50 ppm (75.12%) > Reactive Blue dye of 50 ppm (73.98%)> Reactive Blue dye of 100 ppm (71%)>Reactive Orange of 100 ppm (70%).

TL;DR: In this paper , the incorporation of different percentages of carbon nanofibers (0.6-1-3 and 5%) in a PPS thermoplastic matrix, with the purpose to establish and understand each one of the variables that control crystallization kinetics.
Abstract: The presence of a reinforcement in polymeric materials can cause alterations in their physical properties, and increase the crystallization rate of their polymeric matrix. Therefore, this research work was oriented toward the incorporation of different percentages of carbon nanofibers (0.6-1-3 and 5%) in a PPS thermoplastic matrix, with the purpose to establish and understand each one of the variables that control crystallization kinetics. The results showed a gradual decrease in crystallization times for contents of up to 5% of CNF, where carbon nanofibers act as nucleation sites, accelerating the crystallization process. According to the values obtained in the Avrami exponent, these fell within a range that oscillates from 2.5 to 3 for pure PPS and PPS/1%CNF which indicates that the presence of carbon nanofibers does not have an effect on the nucleation mechanism of polyphenylene sulphide crystalline phase, thus suggesting crystallization with heterogeneous nucleation and two-dimensional growth with circular geometry

TL;DR: In this paper , the microstructure and corrosion behavior of nanocrystalline SUS304 by dry ice shot peening has been investigated in detail in terms of phase transformation.
Abstract: Microstructure and corrosion behavior of nanocrystalline SUS304 by dry ice shot peening has been investigated in detail in term of phase transformation. SUS304 as metastable austenitic stainless has excellent corrosion resistance and induced martensite by shot peening process. However, the SUS304 has quite low strength which is difficult to wear as metallic component. The dry ice shot peening process was carried out on SUS304 surface for one and three hours. The microstructure was observed by transmission electron microscope (TEM) and scanning electron microscope (SEM) equipped with electron back-scattered diffraction (EBSD). The phase transformation was analyzed by X-ray diffraction (XRD). The corrosion testing was carried out in 3.5% NaCl solution. The result indicated that the grain size of SUS304 surface was finer by deformation due to dry ice shot peened process. The hardness was improved properly by the increasing the shot peened time, and the corrosion resistance was increased. The XRD results showed that three hours shot peening process induced martensite phase of SUS304 by 15 m thickness. It can be summarized that the dry ice shot peening can be induced phase transformation due to high deformation on the SUS304 surface

TL;DR: The result obtained from the experiment shows promising result in summarization of Wolaita text, and the researcher justified the model performance with ROUGE evaluation metrics by comparing the system summaries with the expert summaries.
Abstract: Text summarization is the mechanism of summarizing a huge document comprising vast amount of information which is difficult to overcome and understand its message easily in any written documents for whatever languages without losing its entire message. A short and precise document which conveys intended information for the user in demand is expected in this information age. In addition to that, summarizing a document with vast amount of information is very difficult and time consuming specially for less resourced and technologically unfavored languages. Therefore in this study, the researcher proposed to address such problems for Wolaita by using graph based extractive text summarization approach. To attain the goal of this study the researcher prepared 92 documents for the study, explored extractive text summarization with graph-based approach to address the problems, performed text preprocessing tasks and finally developed text summarization model by using TextRank algorithms. The researcher used 92 documents, performed 92 various experiments, on documents and experimental results and findings were discussed in detail. To evaluate the model performance, three different expert summaries were collected for documents and computed system generated summaries with ROUGE evaluation metric. The researcher justified it with ROUGE evaluation metrics by comparing the system summaries with the expert summaries. The result obtained from the experiment shows promising result in summarization of Wolaita text. Finally, the experimental result of a 61.16% recall, 60.69% precision and 60.46% f-measures were obtained.
