Probing the compound effect of spatially varying intrinsic defects and doping on mechanical properties of hybrid graphene monolayers
No full textDoping in pristine 2D materials brings about the advantage of modulating wide range of mechanical properties simultaneously. However, intrinsic defects (such as Stone-Wales and nanopore) in such hybrid materials are inevitable due to complex manufacturing and synthesis processes. Besides that, defects and irregularities can be intentionally induced in a pristine nanostructure for multi-synchronous modulation of various multi-functional properties. Whatever the case may be, in order to realistically analyse a doped graphene sheet, it is of utmost importance to investigate the compound effect of doping and defects in such 2D monolayers. Here we present a molecular dynamics based investigation for probing mechanical properties (such as Young's modulus, post-elastic behaviour, failure strength and strain) of doped graphene (C14 and Si) coupling the effect of inevitable defects. Spatial sensitivity of defect and doping are systematically analyzed considering different rational instances. The study reveals the effects of individual defects and doping along with their possible compounded influences on the failure stress, failure strain, Young's modulus and constitutive relations beyond the elastic regime. Such detailed mechanical characterization under the practically relevant compound effects would allow us to access the viability of adopting doped graphene in various multifunctional nanoelectromechanical devices and systems in a realistic situation.</p
Multi-beam object-localization for millimeter-wave ISAC-aided connected autonomous vehicles
No full textMillimeter wave (mmWave) multiple-input multiple-output (MIMO) systems capable of integrated sensing and communication (ISAC) constitute a key technology for connected autonomous vehicles (CAVs). In this context, we propose a multi-beam object-localization (MBOL) model for enhancing the sensing beampattern (SBP) gain of adjacent objects in CAV scenarios. Given the ultra-narrow beams of mmWave MIMO systems, a single pencil beam is unsuitable for closely located objects, which tend to require multiple beams. Hence, we formulate the SBP gain maximization problem, considering also the constraints on the signal-to-interference and noise ratio (SINR) of the communication users (CUs), on the transmit power, and the constant modulus of the phase-shifters in the mmWave hybrid transceiver. To solve this non-convex problem, we propose a penalty-based triple alternating optimization algorithm to design the hybrid beamformer. Finally, simulation results are provided for demonstrating the efficacy of the proposed model

Constant Factor Approximation Algorithm for Uniform Hard Capacitated Knapsack Median Problem
No full textIn this paper, we give the first constant factor approximation algorithm for capacitated knapsack median problem (CKnM) for hard uniform capacities, violating the budget by a factor of 1+epsilon and capacities by a 2+epsilon factor. To the best of our knowledge, no constant factor approximation is known for the problem even with capacity/budget/both violations. Even for the uncapacitated variant of the problem, the natural LP is known to have an unbounded integrality gap even after adding the covering inequalities to strengthen the LP. Our techniques for CKnM provide two types of results for the capacitated k-facility location problem. We present an O(1/epsilon^2) factor approximation for the problem, violating capacities by (2+epsilon). Another result is an O(1/epsilon) factor approximation, violating the capacities by a factor of at most (1 + epsilon) using at most 2k facilities for a fixed epsilon>0. As a by-product, a constant factor approximation algorithm for capacitated facility location problem with uniform capacities is presented, violating the capacities by (1 + epsilon) factor. Though constant factor results are known for the problem without violating the capacities, the result is interesting as it is obtained by rounding the solution to the natural LP, which is known to have an unbounded integrality gap without violating the capacities. Thus, we achieve the best possible from the natural LP for the problem. The result shows that the natural LP is not too bad
Factor Intensity Reversal and Ergodic Chaos
No full textThis paper studies a two-sector endogenous growth model with labour augmenting externalities or Harrod-Neutral technical change. The technologies are general and the preferences are of the CES class. If con- sumers are su±ciently patient, ergodic chaos and geometric sensitivity to initial conditions can emerge if either (1) there is factor intensity reversal; or (2) if the consumption goods producing sector is always capital intensive. The upper bound on the discount rate is determined only by the transver- sality condition. If utility is linear, there can be chaos only if there is factor intensity reversalErgodic Chaos; Two-sector endogenous growth model; Factor intensity reversal; Labor-augmenting externalities
Modeling the Economic History of the Ganges: From Early Times to Gupta
No full textThis paper presents a mathematical economic model to analyze the trade dynamics along the Ganges River, focusing on the interactions among political stability, technological advancement, guild productivity, and the supply-demand mechanism. The model employs principles from Classical Economics and incorporates elements of Keynesian trade theory. Through a series of equations, we derive equilibrium conditions that describe the economic interactions in the Ganges Valley until the end of the Gupta period. The formulation accounts for diminishing returns, interdependencies among factors, and their combined effects on trade volume
The Tribal Issue, 1964-1984
No full textThe paper explores basic assumptions of the tribal policy of Congress governments in post-colonial India (1964-1984), and traces its gradual evolution over the decades. In the long run the tribal people still remained marginalised in the economic, cultural and political life of the country
