Abstract:

The procession in the area of internet due to wireless networking technologies gives rise to multiple new applications. In the past few decades, we have found many advance developments in wireless networks. With these developments and large number of applications that are being provided by MANETs, we still face some challenges that have to be overcome. The baseless and active nature of these networks demand new set of networking schemes that should be implemented to provide effective peer-to-peer communication. MANETs hire traditional TCP/IP structure to provide this peer-to-peer communication

Abstract:

Mobile Ad-hoc Networks (MANETs) have emerged as a viable paradigm for creating dynamic communication between mobile nodes in the absence of a permanent infrastructure. However, since MANETs are inherently decentralized and self-organizing, they are vulnerable to a variety of security concerns, especially when hostile nodes seek to interrupt communication and undermine network operations. As a consequence, developing efficient and robust routing protocols is critical to ensuring dependable and secure data transmission in MANETs.

Abstract:

Abstract High heat flux and radio blackout are well-known challenges space vehicles have been facing during re-entry into a planet’s atmosphere since the early days of space-flight. Thermal protection systems have been developed to protect spacecraft and astronauts, however, they are often heavy and some have to be replaced after each mission. High temperatures in the compressed gas in the shock wave lead to partial ionization. The dense plasma can cause radio blackout, i.e. attenuation or reflection of radio waves thus blocking data-telemetry and communication with ground stations or satellit

Introduction: Mixed adenoneuroendocrine carcinoma (MANEC) is an uncommon and aggressive tumor arising throughout the entire gastrointestinal tract. Treatment options are limited, and survival is dismal with conventional therapies. Case description: We present the case of a 66-year-old man who was diagnosed with a locally advanced MANEC of the gastroesophageal junction. He was treated with perioperative chemotherapy and total gastrectomy. After anastomotic tumor recurrence was detected, he underwent three systemic regimens, including chemoradiotherapy. The patient was then tested for mismatch r

Abstract:

In March 1999, electrostatic accelerator, Tandetron (Model 4117MC, High Voltage Engineering Europe Co.) was installed in the Electrostatic Accelerator Building for PIXE (Particle Induced X-ray Emission) analysis. The accelerating voltage is 0.4 to 1.7MV, and the maximum beam current is 5μA at 3.4MeV. This system has three beam ports for different types of PIXE analysis: normal, micro-beam and in-air. The first beam port is used for normal PIXE. Since two types of X-ray detecting device, Si ( Li ) and CdZnTe detectors, are available here, elements from Na ( Z =11) to U ( Z =92) are detectable.

With the development of economy, the energy demand is becoming bigger and bigger, the development of wind energy is one of the main ways to solve energy crisis. In terms of energy utilization, high power wind power connected to the grid is currently one of the most effective ways of wind energy utilization. The wind power generation system connected to the grid plays the role of the changing wind energy into mechanical energy by wind turbines, and then converts mechanical energy into electrical energy by a generator. Because CSCF wind turbine works with the gearbox, which is low efficiency, no

Abstract:

Surface defects on the permanent magnetic ferrite magnet rotor are the primary cause for the decline in performance and safety hazards in permanent magnet motors. Machine-vision methods offer the possibility to identify defects automatically. In response to the challenges in the permanent magnetic ferrite magnet rotor, this study proposes an improved You Only Look Once (YOLO) algorithm named SAB-YOLOv5. Utilizing a line-scan camera, images capturing the complete surface of a general object are obtained, and a dataset containing surface defects is constructed. Simultaneously, an improved YOLOv5
