Cyber Resilience through Real-Time Threat Analysis in Information Security

International Journal of Communications, Network and System Sciences 2024年第4期17卷 51-67页

作者： Aparna Gadhi Ragha Madhavi Gondu hitendra Chaudhary Olatunde Abiona Department of Computer Information Systems Indiana University Northwest Gary IN USA

This paper examines how cybersecurity is developing and how it relates to more conventional information security. Although information security and cyber security are sometimes used synonymously, this study contends that they are not the same. The concept of cyber security is explored, which goes beyond protecting information resources to include a wider variety of assets, including people [1]. Protecting information assets is the main goal of traditional information security, with consideration to the human element and how people fit into the security process. On the other hand, cyber security adds a new level of complexity, as people might unintentionally contribute to or become targets of cyberattacks. This aspect presents moral questions since it is becoming more widely accepted that society has a duty to protect weaker members of society, including children [1]. The study emphasizes how important cyber security is on a larger scale, with many countries creating plans and laws to counteract cyberattacks. Nevertheless, a lot of these sources frequently neglect to define the differences or the relationship between information security and cyber security [1]. The paper focus on differentiating between cybersecurity and information security on a larger scale. The study also highlights other areas of cybersecurity which includes defending people, social norms, and vital infrastructure from threats that arise from online in addition to information and technology protection. It contends that ethical issues and the human factor are becoming more and more important in protecting assets in the digital age, and that cyber security is a paradigm shift in this regard [1].

Effect of Plasma Density on Proton Acceleration in a Rectangular Waveguide

引用

Plasma Science and Technology 2004年第5期6卷 2456-2458页

作者： hitendra K.Malik Department of Physics Indian Institute of Technology DelhiNew Delhi-110016Indianalytical studies are made for the proton acceleration during its motion in thefields of the fundamental mode excited by a high-intensity microwave in a rectangular waveguidewhen the proton is injected along the propagating direction of the mode. The trajectory of theproton is calculated and the expressions are obtained for the energy gain and acceleration gradienttogether with the effects of plasma density microwave frequency and waveguide width. Energygain of 181 keV is attained by a 50 keV proton in a 0.015m×0.020 m evacuated waveguide when0.5×10~(10)W/m~2 microwave intensity is used. However this gain increases to 1387 keV whenthe waveguide is filled with a plasma having a density of 1.0×10~(19) m~(-3). Higher accelerationgradients are achieved when the proton is injected with a higher initial energy and also when themicrowave intensity increases. The effects of the microwave frequency and width of the waveguideare found to decrease the acceleration gradient.

A Straight-bladed Vertical Axis Wind Turbine with a Directed Guide Vane Row-Effect of Guide Vane Geometry on the Performance-

引用

Journal of Thermal Science 2009年第1期18卷 54-57页

作者： Manabu TAKAO Hideki kuma Takao MAEDA Yasunari KAMADA Michiaki OKI Atsushi MINODA Department of Mechanical Engineering Matsue National College of Technology Department of Mechanical Engineering Mie University

The objective of this study is to show the effect of guide vane geometry on the performance. In order to overcome the disadvantages of vertical axis wind turbine, a straight-bladed vertical axis wind turbine （S-VAWT） with a directed guide vane row has been proposed and tested by the authors. According to previous studies, it was clarified that the performance of the turbine can be improved by means of the directed guide vane row. However, the guide vane geometry of S-VAWT has not been optimized so far. In order to clarify the effect of guide vanegeometry, the effects of setting angle and gap between rotor blade and guide vane on power coefticlent and start- ing characteristic were investigated in the experiments. The experimental study of the proposed wind turbine was carried out by a wind tunnel. The wind tunnel with a diameter of 1.8m is open jet type. The wind velocity is 8 m/s in the experiments. The rotor has three straight blades with a profile of NACA0018 and a chord length of 100 mm, a diameter of 0.6 m and a blade height of 0.7 m. The guide vane row consists of 3 arc plates.

Hydrogels are highly porous three-dimensional crosslinked polymer networks consisting of hy-drophilic polymers,employed most practically in medicine and industry,often as *** hydrogels suffer limitations in their mechanical properties,such as tensile and com-pression,and freeze at sub-zero temperatures,which compromise their ability as useful *** this study,the incorporation of L-ornithine-based zwitterionic monomer(OZM),titanium carbide(MXene),and glycerol within polyacrylamide hydrogels was used to prepare a novel polyacrylamide/polyL-ornithine-based zwitterion/MXene(PAM/Porn/MXene)hydrogel to im-prove the mechanical,adhesion,and anti-freezing properties of pure polyacrylamide *** study also analyzed the mechanical strength(tensile and compression),adhesion,and anti-freezing properties of a novel PAM/Porn/MXene hydrogel at 1%,4%,and 10%MXene concen-trations to establish to what extent the conductive MXene material enhanced these properties and concluded that the tensile and compressive properties improved linearly with the increase in the concentrations of MXene,adhesion decreased with the increased MXene concentrations,and syn-ergistic interaction between MXene and OZM significantly improved the anti-freezing properties up to-80°C.
