The investigation of network security, including penetration attacks and potential security mechanisms

TL;DR: In this paper , the authors investigate various types of assaults and different types of security mechanisms that might be applied based on the network's needs and architecture to defend against network security threats.
Abstract: - Security is an important aspect of computing and networking technology. The first and most important aspect of any network design, planning, construction, and operation is the significance of a solid security strategy. Network security is becoming increasingly critical to personal computer users, businesses, and the military. With the introduction of the internet, security has become a big problem. Many security threats were made possible by the internet's structure. Because of the ease with which intellectual property can be obtained via the internet, network security is becoming increasingly important. When an attack is sent via a network, it can take several forms. Knowing the attack mechanisms enables adequate security to evolve. Many businesses protect themselves from the internet by using of Firewalls and encryption methods are examples of security measures. On global networking infrastructures, there is a vast number of personal, commercial, military, and government information, all of which necessitates different security procedures. In this research, we attempt to investigate numerous types of assaults as well as various types of security mechanisms that might be applied based on the network's needs and architecture.

TL;DR: The implications of various types of terrain on the employment and deployment of Mini UAS and the capabilities of the system with respect to terrain in which it is expected to operate are explored.
Abstract: PurposeAmongst all classes of unmanned aircraft system (UAS), the rise of the Mini UAS class is the most dominant. Mini UASs are field-deployable systems and hence are not expected to operate from a runway. Therefore, the operating terrain plays an important role in the deployment and employment of the Mini UAS. However, there is limited published work in this area. The impact of terrain is more critical for military applications than civilian applications. The purpose of this paper is to explore the implications of various types of terrain on the employment and deployment of Mini UAS.Design/methodology/approachThis paper explores the implications of various types of terrain on the employment and deployment of Mini UAS.FindingsMini UAS with field deployable requirements is often launched within the tactical battle area in case of military applications or in close proximity to the intended target area for civilian applications. Due to the size and weight of the Mini UAS, launch and recovery becomes an important factor to be considered. Rotary wing or fixed-wing vertical take-off and landing configuration UAS overcomes the limitations of Mini UAS and hence it is the preferred option. Impact of the terrain is significantly higher for military applications as compared to civil applications. Mountain terrain is the most challenging for Mini UAS operations.Practical implicationsThis paper will help the designers configure the UAS as per the operating terrain.Originality/valueTerrain affects the deployment and employment of Mini UAS and the capabilities of the system with respect to terrain in which it is expected to operate must be considered during the design of a Mini UAS. The paper will help the designers configure the UAS as per the operating terrain.

TL;DR: In this paper, a 2D numerical model has been developed where the effect of number of turns on the AC losses for magnet coils/stacks has been examined using SCS 12050 tape having 12mm width and critical temperature as 240 A. The model is being tested for a sinusoidal input having 50 Hz frequency for the full cycle.
Abstract: Coated conductors are widely employed in various power applications including superconducting motors, fault current limiters, energy storage, transmission and distribution systems etc. Ideal 2G (YBCO) superconductors are having almost zero resistance when cooled below 90K and can carry currents without loss. Coated conductors are made from Yttrium-Barium ceramic powder where stabilizer and substrate are being coupled together to strengthen the tape architecture. Practically, AC losses are found to occur when current is flowing through the tape and the losses are high when large currents flowing through the coated conductors. In this work, a 2D numerical model has been developed where the effect of number of turns on the AC losses for magnet coils/stacks has been examined using SCS 12050 tape having 12mm width and critical temperature as 240 A. The numerical model is based on H-formulations integrated with E-J Power law where homogenized approach has been proposed to estimate the magnetic flux density and AC losses. The model is being tested for a sinusoidal input having 50 Hz frequency for the full cycle.

TL;DR: In this article, the authors analyse different aerofoils and study their flutter behavior and trying to understand the influence the aerofoil parameters has on the dynamic aero-elastic behaviour of the wing that is constructed by that aerofilament.
Abstract: The objective behind this work is to analyse different aerofoils and study their flutter behaviour and the trying to understand the influence the aerofoil parameters has on the dynamic aero-elastic behaviour of the wing that is constructed by that aerofoil. In an attempt to understand this, wings of same span and chord dimensions are constructed using different aerofoil sections which have different camber locations. One way FSI analysis was performed and the mode frequencies were extracted to observe the flutter of the wing. An attempt to understand the impact the aerofoil shape has on the wing flutter is made by selecting different aerofoil sections that has a varying camber location from the leading edge.
