TL;DR: This work aims to assess and validate the deformation behavior of carbon fiber reinforced epoxy composite during high speed machining and shows good correlation with experiments.
Abstract: In recent time, carbon fiber reinforced plastics (CFRP) are used in important applications in aerospace, automobile, sporting equipment’s, biomedical instruments, etc High-speed machining of this material can regulate the cutting conditions to maximize production output Investment for this process is at minimal cost which has been the generic aim of manufacturing industries all over the world In order to accomplish this, Finite Element (FE) models have been developed for critical applications Such numerical analysis negates the need for exhaustive experimental trials needed to estimate various parameters involving in machining This has been the reason instrumental in coercing industries to resort to FE analysis for simulating cutting processes The present work aims to assess and validate the deformation behavior of carbon fiber reinforced epoxy composite during high speed machining Orthogonal turning was performed for varied cutting conditions by varying cutting speed and feed at a constant depth of cut An FE model was constructed using ABAQUS V613 and the effective stress–strain response and deformation were analyzed The simulated results for cutting force, thrust force and feed force showed good correlation with experiments

TL;DR: In this paper, the dipole moments and the theoretical vibrational frequencies of di-hydroxy benzenes were analyzed and it was shown that the vibrational frequency reflects steric hindrance caused by the position of the two hydroxyl groups and confirm the earlier findings of CC bond elongation or contraction and ∠CCO bending.
Abstract: Dihydroxy benzenes are of considerable interest because the stabilities of the molecular H-bond as well as the interaction between the pi charges of the benzene ring and the OH group[1]. The three isomers of di-hydroxy benzene namely, catechol, resorcinol, hydroquinol are taken into consideration here. Gaussian software[2] was used to carry out the studies. The dipole moments and the theoretical vibrational frequencies are analyzed. Only hydroquinol being a symmetrical molecule has a zero dipole moment. Substitution also has a marked effect on the dipole moment. The dipole moment is extremely high for tetra substitution. The vibrational frequencies reflect the steric hindrance caused by the position of the two hydroxyl groups and confirm the earlier findings of CC bond elongation or contraction and ∠CCO bending.

TL;DR: In this paper, the authors proposed a delay aware bandwidth estimation and intelligent video transcoder in mobile cloud, which is based on Markov Decision Process (MDP) model to estimate the best bandwidth of mobile using reward function.
Abstract: In recent years, smartphone users are interested in large volumes to view live videos and sharing video resources over social media (e.g., Youtube, Netflix). The continuous streaming of video in mobile devices faces many challenges in network parameters namely bandwidth estimation, congestion window, throughput, delay, and transcoding is a challenging and time-consuming task. To perform these resource-intensive tasks via mobile is complicated, and hence, the cloud is integrated with smartphones to provide Mobile Cloud Computing (MCC). To resolve the issue, we propose a novel framework called delay aware bandwidth estimation and intelligent video transcoder in mobile cloud. In this paper, we introduced four techniques, namely, Markov Mobile Bandwidth Cloud Estimation (MMBCE), Cloud Dynamic Congestion Window (CDCW), Queue-based Video Processing for Cloud Server (QVPS), and Intelligent Video Transcoding for selecting Server (IVTS). To evaluate the performance of the proposed algorithm, we implemented a testbed using the two mobile configurations and the public cloud server Amazon Web Server (AWS). The study and results in a real environment demonstrate that our proposed framework can improve the QoS requirements and outperforms the existing algorithms. Firstly, MMBCE utilizes the well-known Markov Decision Process (MDP) model to estimate the best bandwidth of mobile using reward function. MMBCE improves the performance of 50% PDR compared with other algorithms. CDCW fits the congestion window and reduces packet loss dynamically. CDCW produces 40% more goodput with minimal PLR. Next, in QVPS, the M/M/S queueing model is processed to reduce the video processing delay and calculates the total service time. Finally, IVTS applies the M/G/N model and reduces 6% utilization of transcoding workload, by intelligently selecting the minimum workload of the transcoding server. The IVTS takes less time in slow and fast mode. The performance analysis and experimental evaluation show that the queueing model reduces the delay by 0.2 ms and the server’s utilization by 20%. Hence, in this work, the cloud minimizes delay effectively to deliver a good quality of video streaming on mobile.

TL;DR: A cross layered reconfigurable protocol for routing with multiple transceivers called as optical sphere in FSO MANET is developed in NS‐2 and surpasses the existing works in terms of delay, delivery ratio, and residual energy.
Abstract: In Free Space Optic Mobile Ad hoc Networks (FSO MANET), during data transmission through hierarchical routing protocol, the route failure may either occur if the node has expired due to energy drain or if the node is not positioned with the succeeding hop node owing to mobility. To circumvent these obstacles, in this work, a cross layered reconfigurable protocol for routing with multiple transceivers called as optical sphere in FSO MANET is developed in NS‐2. In this protocol, the nodes are clustered, and the cluster head is selected using network source connector. If any of the cluster member expire due to energy drain and if the alternate path is not available in the routing table, then the source will perform route reconfiguration to change the orientation and transmission radius of the node resulting in direct transmission of packet to cluster head. During data transmission through re‐configured route, if the node interface is positioned with respect to the succeeding hop node, then the packet can be delivered. Otherwise, per‐flow buffer algorithm is used for re alignment. Results simulated show that the proposed protocol surpasses the existing works in terms of delay, delivery ratio, and residual energy.
