Handoff Call Queuing in Distributed Dynamic Channel Allocation Strategy
Abstract: ABSTRACT It is important to utilize the channels very efficiently in cellular system as these channels are meager. In this paper, A Distributed Dynamic Channel Allocation (DDCA) strategy is applied for channel allocation in 9-cell system having non-uniform traffic. Square shape cells with nine cell cluster size have been considered for model development with GSM 1800 specification. The model also considers fixed channel reservation (5–15% of total channel per cell) …

Understanding Airborne Pathogens: Pathways, Risks, and Control Strategies
Abstract: Airborne transmission is the transfer of germs through the air, mostly by respiratory droplets and aerosols that come out when you cough, sneeze, talk, or breathe. These particles can stay in the air for a long time and move a long way, especially in small or poorly ventilated places. Mycobacterium tuberculosis, measles virus, varicella-zoster virus (chickenpox), influenza virus, and more recently, SARS-CoV-2 are all infections that can be spread through …

Thin fluoropolymer coating on cotton textile to achieve hydrophobicity
Abstract: We report a simple novel procedure to prepare hydrophobic cotton textiles by admicellar polymerization on the cotton surface. By in situ introducing fluoropolymer on cotton fibers to generate a dual-size surface roughness, followed by hydrophobization with a little amount of fluoromonomer Octafluoropentamethyl methacrylate (OFPM) with short time, normally hydrophilic cotton has been easily turned in to hydrophobic. Hydrophobic cotton textile exhibits a static water contact angle of 135° for a …

Influence of Gd Doping in Structural, Morphological and Optical Properties of Zno Nanostructures Synthesised Via Sol-Gel Processes
Abstract: In this study, nanocrystalline Zn1-xGdx (x=0.0 and 0.03) samples were synthesised via the Sol-gel combustion process. An array of analytical techniques was employed to examine the prepared samples to determine their different physical features. For both pristine and Gd-doped samples, the crystal symmetry is hexagonal with the P63mc space group which is verified via the Rietveld refinement analysis of X-ray diffraction (XRD) data. The atoms' bond length Zn-O and bond …

Dynamic Hardness Trend of Tribological Steels Used for Advanced Power Transmission Assembly
Abstract: Gravity drop technique was used for measuring dynamic hardness trend of M50, 52100 and 4340 tribological steels. Work hardened state increased dynamic hardness, while shear bands and dynamic recovery of dislocations induced dynamic softening. Descending order of work hardening for the investigated steels is M50-52100-4340. The threshold strain to begin the softening gradually increases in the order M50-52100-4340 steels. Descending order of work softening beyond threshold strain for the investigated …
