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: In this paper, a review sheds light on the traits behind an albatross's aerodynamic efficiency such as dynamic soaring, bell shaped lift distribution and provides insights into its hereditary posed encodings and evolutions.
Abstract: The aerodynamic efficiency of the albatross has always fascinated researchers and the designing of drones mimicking the albatross's aerodynamic traits have been a major area of interest for the aerospace industry. This review sheds light on the traits behind an albatross's aerodynamic efficiency such as dynamic soaring, bell shaped lift distribution and provides insights into its hereditary posed encodings and evolutions. The soaring techniques have been introduced and discussed along with the albatross's morphology and structure which is responsible for its efficiency. In addition, the albatross's navigational and foraging strategies are briefly discussed to provide a better understanding of the effects of atmospheric conditions on the albatross's flight characteristics and the limitations.

TL;DR: In this article, an airfoil incorporated with a mechanism to provide negative camber is studied in detail and simulation has been performed to note the differences and lift generation from that wing.
Abstract: Modern day aerospace engineering is enabling us with new innovative methods to overcome he existing challenges faced by the aircrafts at higher altitude. Camber morphing of wing is a concept to increase the lift significantly while eliminating the use of flaps. The new smooth surface design will eliminate or reduce the drag and will upsurge maneuverability along with fuel efficiency. Wings are crucial part for an aerodynamic flight, the shape and mechanism incorporated in the wing directly affects the lift generation. an airfoil incorporated with a mechanism to provide negative camber is studied in detail. Analysis and simulation has been performed to note the differences and lift generation from that wing. Changing shape of the wing at different flight conditions has been studied and a model was designed in CATIA V5. Theoretical and experimental values are compared and aerodynamic performance is analyzed.

TL;DR: In this article, a multi-hole conical probe is employed to determine the velocity of the air flow, total and static pressures of the wind tunnel, wave angle in addition to estimating the noise of the test segment.
Abstract: A multi-hole conical probe is employed to determine the velocity of the air flow, total and static pressures of the wind tunnel, wave angle in addition to estimating the noise of the test segment. It twinkles with the unique qualities of being trouble-free, vigorous with the flexibility to be applied even in ruthless situations. Our innovative conical wedge type probe is launched by means of AUTOCAD and engineered by exploiting the stain less steel material. The pressure holes are situated at the end of the conical probe which is applied to calculate the pressure and flow velocity of the atmosphere. The novel probe is performed at supersonic settings by the effective use of the proficient Computational Fluid Dynamic Analysis (CFD analysis) software. It discharges the task of assessing the enduring competence of the projected probe under a variety of situations like fixed pressure and temperature along with the velocity of the air flow at different mach-numbers. This sample fashioned blueprint built up in CFD is estimated under supersonic backdrops up to mach 3. Thus, it is crystal clear that that our well-conceived sample developed with semi nose angle 20o ushers in a sterling performance in mach 2.8 triggering an incredible shock wave of 29.3o

TL;DR: In this paper , a consideration of the coaxial rotor Mini UAV to analyse the suitability for mountain terrain is presented, and various design parameters are analyzed to arrive at viable design configurations for coaxial rotary wing UAVs to operate in mountain terrain.
Abstract: Due to its compactness, agility, good hover performance, and ease of carriage, coaxial rotor Mini UAV is apt for various military and civilian applications in mountain terrain. This paper examines various factors to arrive at viable configurations of coaxial rotor Mini UAV for applications in mountain terrain. A consideration of the coaxial rotor Mini UAV to analyse the suitability for mountain terrain is presented. Coaxial rotor design is evaluated to assess the design requirements of mountain terrain. Various design parameters are analysed to arrive at viable design configurations for coaxial rotor Mini UAVs to operate in mountain terrain. Due to mechanical complexities, more than three blades per rotor for a small coaxial rotary wing aircraft is not recommended. The compact frame of the coaxial rotor Mini UAV is a key advantage, so rotor blades with a radius bigger than 1 m are not desirable. With a radius smaller than 1 m, a range of 0.9 m to 1.2 m, and an rotor speed between 900 RPM and 1200 RPM for 3-blade and 2-blade coaxial rotors, the Mini UAV offers a variety of options for applications in mountain terrain.

TL;DR: The interrelation between design, end-use requirements and terrain restrictions presented in the paper provides an insight into the implications of the design configurations of Mini UAS for various applications.
Abstract: Mini Unmanned Aircraft Systems (UAS) present distinct design challenges due to their man-portable, field-deployable profile. The implications of various unmanned aerial vehicle (UAV) design configurations for Mini UAS applications are discussed in this study. Fixed-wing, rotary-wing, and hybrid Mini UAS design configurations are analysed and compared based on performance parameters specified by various manufacturers to assess appropriateness for military and civil applications. Mini UAS designed for military applications can meet most requirements in the civil domain. However, the reverse is seldom feasible because of several restrictions imposed by combat conditions. Fixed-wing Mini UAS have significant limitations for military applications, primarily because of launch and recovery considerations. For civil applications, the fixed-wing configuration provides multiple advantages. The benefit of the rotary-wing configuration's compact size to overcome various battlespace restrictions for military applications does not translate to other performance parameters, and this is a serious limitation for its applications. The hybrid profile has significant design advantages that can be leveraged for both military and civil applications. The interrelation between design, end-use requirements and terrain restrictions presented in the paper provides an insight into the implications of the design configurations of Mini UAS for various applications.
