Common Header Pulsating Heat Pipe (CHPHP) is a two-phase passive heat transfer device made by replacing the multiple U-bends of a conventional Pulsating Heat Pipe (PHP). The present CHPHP model consists of ten parallel channels in the adiabatic section and common channels at the evaporator and condenser sections. The flat design at the evaporator and condenser should facilitate a better contact area with the surface to be cooled and heat rejected, thus justifying the design modification. The ...

Gas foil thrust bearings (GFTBs) have a wide range of applications in oil-free turbo machinery due to their advantages such as low maintenance, high speed ability, environmental friendliness, and wide range of temperature adaptability. However, the use of GFTBs is limited due to the low load-carrying capacity (LCC). This study develops a novel GFTB, engraving the straight radial grooves on the top foil surface to enhance the LCC. For numerical simulations, the 2D compressible, isothermal and ...

Gas foil journal bearings (GFJBs) have received a lot of interest in modern turbomachinery because of their outstanding performance, especially in high-speed and high-temperature environments. The surface texture of bearings plays a crucial role in increasing load-carrying capacity, minimizing friction, and boosting overall efficiency. Nature-inspired designs, such as the convergent, divergent, and constant-width herringbone textures, offer innovative solutions to optimize these characteristi...

We investigate how superhydrophilic confinement influences the thermodynamic and structural properties of water using molecular dynamics simulations with the coarse-grained monatomic water (mW) model. This work builds on our recent study of water confined within slit pores of varying widths and wall-fluid interaction strengths, focusing on properties such as density, enthalpy, potential energy, entropy, specific heat capacity, and structural ordering [1]. Strong wall-fluid interactions signif...

For a finite group 𝐺, define 𝛼(𝐺) as the minimum number of vertices among all graphs Γ such that Aut Γ ∼= 𝐺 [1]. For any 𝑝 prime, all 𝑝-groups of order 𝑝𝑛 having cyclic subgroups of order 𝑝𝑛−1 have been completely classified. Several authors have already investigated some of these families of groups in order to find vertex-minimal graphs [2]. Here we consider a family of groups called modular 𝑝-groups, for an odd prime 𝑝 and 𝑛 ≥ 3. A modular 𝑝-group is defined as Mod𝑛(𝑝) = ⟨𝑎...

In this research, we introduce a novel co-linearly polarized in-band full-duplex (FD) antenna that achieves passive self-interference cancelation (SIC) through high Tx-Rx isolation. The proposed FD antenna of size 0.014 λ30 is designed to operate within the IEEE 802.11p band (5.850 GHz to 5.945 GHz) for V2XITS applications. This isolation improvement is made possible by the proposed FD antenna, which does not need a complex or hybrid feed network or circulator. The study investigates the appl...

Safety management is a paramount task in the Nepalese construction industry, constituting a key aspect for measuring project success alongside factors such as time, cost, and quality performance. It encompasses various initiatives, processes, and regulatory compliances set by different governmental bodies. Often, the efficacy of safety management efforts is contingent upon resource availability. However, the influence of resource availability on safety management strategies (SMS) within the N...

Fatigue, characterized by significant physical or mental exhaustion resulting from stress, insufficient rest, or extended physical activity, can impair both cognitive functioning and physical capabilities. This condition increases the likelihood of accidents and detracts from overall well-being and performance. The present research investigates the potential of speech-based analysis as a non-invasive and objective method for detecting exercise-induced fatigue. As individuals become fatigued, ...

Power analysis attacks have become a major problem in VLSI circuits. The attackers extract sensitive information of SRAM cells through side-channel attacks (SCAs), and hence, leakage power analysis attack (LPAs) has become a serious concern to the security systems. To provide reliability and security to these cells, a modified leakage-attack-resilient 8T (MLAR- 8T) SRAM cell has been proposed. The simulations are done using Cadence Virtuoso in 65nm CMOS technology at 27°C. The proposed single...

Healthcare is crucial for creating human capital, preserving global well-being, and contributing to development. The most significant obstacles to establishing universal health coverage in India are the unequal distribution of fiscal resources and the lower prioritization of budgets for healthcare. In this context, the paper examines the convergence in healthcare expenditure for 22 Indian states from 1990 to 2020. It employs the club convergence approach proposed by Phillips and Sul (2007) to...
