Molecular Docking Study of Conformational Polymorph: Building Block of Crystal Chemistry

Two conformational polymorphs of novel 2-[2-(3-cyano-4,6-dimethyl-2-oxo-2H-pyridin-1-yl)-ethoxy]-4,6-dimethyl nicotinonitrile have been developed. The crystal structure of both polymorphs (1a and 1b) seems to be stabilized by weak interactions. A difference was observed in the packing of both polymorphs. Polymorph 1b has a better binding affinity with the cyclooxygenase (COX-2) receptor than the standard (Nimesulide)

ANALYSIS OF DIFFERENT MAC PROTOCOLS FOR WIRELESS SENSOR NETWORKS

A developing technology called wireless sensor networks is employed in many fields, including healthcare, process control, even environmental control. In WSNs, a lot of little, resource-constrained nodes are used to gather data and send it to the sink node. It is crucial to create medium access control (MAC) protocols in WSNs that are both reliable and power due to the limited resource and processing ability of a nodes. In this essay, various MAC protocols for wireless sensor networks are examined. S-MAC, T-MAC, and Controller area are the three most popular MAC protocols that are the subject of this study. The analysis is based on a number of factors, including fairness, throughput, energy usage, and latency. Key words: Wireless Sensor Networks, MAC Protocols, S-MAC, T-MAC, Controller Area, Reliability, Power Efficiency, Resource-Constrained Nodes, Fairness, Throughput, Energy Usage, Latency

Computational Analysis of Local Fractional LWR Model Occurring in a Fractal Vehicular Traffic Flow

In this paper, we implement computational methods, namely the local fractional natural homotopy analysis method (LFNHAM) and local fractional natural decomposition method (LFNDM), to examine the solution for the local fractional Lighthill–Whitham–Richards (LFLWR) model occurring in a fractal vehicular traffic flow. The LWR approach preferably models the traffic flow and represents the traffic patterns via the supposition of speed–density equilibrium relationship and continuity equation. This model is mostly preferred for modeling of traffic flow because of its simple approach and interpretive ability to examine the qualitative patterns of traffic flow. The methods applied here incorporate the local fractional natural transform (LFNT) and derive the solutions for the LFLWR model in a closed form. Two examples are provided to demonstrate the accuracy and efficiency of the suggested methods. Furthermore, the numerical simulations have also been presented for each of the examples in the fractal domain. Additionally, the explored solutions for both examples have also been compared and are in good match with already existing solutions in literature. The methods applied in this work make the computational process easier as compared to other iterative methods and still provide precise solutions
