Accidents are the leading causes of injuries and fatality rate raises vulnerably in automobile. The need of additional safety options to reinforce the active safety in vehicles. The foremost reason behind the accident is drivers fault and braking inefficiency. Automatic braking and additional features are incorporated in high cost vehicles not in low cost vehicles. The research is carried on the low cost vehicles to prevent drivers from collisions which are cost effective. Therefore the result suggested that more than 16 to 20 percentage of collision occurs due to driver’s health issues. The drivers fault is monitored and braking efficiency is enhanced by using the proposed system. The proposed system used to monitor the condition of the driver by inserting sensor in steering wheel for pulse measuring. The mechanical plunger for actuating the braking system is incorporated to prevent the collision during health issues. During abnormal condition of the driver the pulse sensor gives the signal to the controller to activate the hydraulic plunger connected to the brake pedal. The actuator which is placed above the brake pedal and it is compressed when the signal from the controller to compress the brake pedal during demand. The proposed system analysis the condition of driver to enhance the protection to the driver and retards the vehicle speed to prevent the accidents.

Spin chains have long been considered an effective medium for long-range interactions, entanglement generation, and quantum state transfer. In this work, we explore the properties of a spin chain implemented with superconducting flux circuits, designed to act as a connectivity medium between two superconducting qubits. The susceptibility of the chain is probed and shown to support long-range, cross chain correlations. In addition, interactions between the two end qubits, mediated by the coupler chain, are demonstrated. This work has direct applicability in near term quantum annealing processors as a means of generating long-range, coherent coupling between qubits. © 2021, CC BY.

Dental problems such as tooth ache and other related disorders are very common among people irrespective of countries. The contemporary food consuming culture aggravated dental issues especially among children who all are suffering a lot. Dental science is a part of medical science has introduced several advancements as remedies in tackling these problems. Nevertheless, the focus is still on researches to explore the effective solutions in the removal of tooth caries. Conventional techniques prefer the tooth removal as preventive measure to end the dissemination of tooth caries. Drilling is an example for conventional practice in caries removal followed by filling with amalgam and other means of filling. This tooth elimination and subsequent processes leads to heat generation, vibrations and noise inducement in the processing tooth. Consequently, patient suffers from pain. Drill-less dentistry is a novel technique that can handle the caries removal without any painful moments. The present work is concerned with drill-less dentistry and come up with a solution in the form of mathematical expression for caries removal rate. The derivation of respective expression revealed that mass flow rate, impact velocity and density of particles (abrasives) are the most influencing factors in deciding the caries removal rate.

Many of the manufacturing industries use sheet metal for optimizing the weight of the products. Forming process has been successively increasing during the past few decades. Indexing mechanisms have been used in milling, weaving, packing, etc. for continuous production purpose. Shearing of sheet metals has been widely used for optimizing the weight of the components and products. Crank slotter mechanism was widely used in the mechanisms for intermittent operations. This has been replaced by Geneva mechanism. The paper aims at deriving the mathematical relations for slotted Geneva wheel using curve theory. The kinematic characteristics are derived using the DH notations Finite element analysis has been done on the designed Geneva wheel with pin. It is analysed for the contact stresses when the drive crank pin slides along the slots of the wheel to operate the mechanism.

As more mobile users become subscribers of content services, their subscribed content can be directly pushed from the content provider into the user equipment after the content is generated. In current and future network paradigms, a joint wired and wireless transmission design for this pushing is needed to guarantee the user experience without the extra deployment of communication infrastructures or consumption of resources. In this paper, we investigate a joint wired and wireless content delivery system that incorporates wired and wireless multicast. The users in the same group are served by wireless multicast from a base station (BS), while the BSs of the same content form a multicast tree in a backbone wired network. The sum of wired and wireless traffic is minimized by a joint design of user grouping, subchannel allocation, wired routing, and wired link usage. Exploiting the monotonicity of wired and wireless traffic with regard to the wired hop count, the original problem is converted for searching the optimal hop count vector that achieves the minimum sum of both types of traffic, which is solved by a monotonic optimization (MO)-based iterative algorithm. Compared with existing schemes and according to the numerical results, a reduction in total traffic of 43% can be achieved by our approach. © 2019 IEEE.

—By taking full advantage of Computing, Communication and Caching (3C) resources at the network edge, Mobile Edge Computing (MEC) is envisioned as one of the key enablers for the next generation network and services. However, current fixed-location MEC architecture may not be able to make real-time decision in dynamic environment, especially in large-scale scenarios. To address this issue, in this paper, a Heterogeneous MEC (H-MEC) architecture is proposed, which is composed of fixed unit, i.e., Ground Stations (GSs) as well as moving nodes, i.e., Ground Vehicles (GVs) and Unmanned Aerial Vehicles (UAVs), all with 3C resource enabled. The key challenges in H-MEC, e.g., mobile edge node management, real-time decision making, user association and resource allocation along with the possible Artificial Intelligence (AI)-based solutions are discussed in this paper. In addition, an AI-based joint Resource schEduling (ARE) framework is proposed, with simulation results shown to verify the efficiency of our proposed framework. Copyright © 2020, The Authors.

In recent decades, the bioinformatics, biology and biotechnology plays a major role in accumulation of numerous biomedical data, which offers an in-depth analysis. On other hand, with the advent of data mining research leads to the development of scalable and efficient models for mining some interesting data pattern in case of small or large databases. It is hence essential to bridge bioinformatics with data mining models for successful implementation of finding the meaning pattern in case of biological data. In this paper, we present a comprehensive survey on various data mining models that helps in analyzing the chemical bonding and its structured index in case of sequential pattern mining.

The loading-aware energy saving scheme for EPON networks

The loading-aware energy saving scheme for EPON networks

引用

作者： Liu, Chien-Ping Wu, Ho-Ting Ke, Kai-Wei Chien, Chia-Chih Department of Computer Science and Information Engineering National Taipei University of Technology No. 1 Sec. 3 Chung-Hsiao E. Rd.

This paper proposes an energy saving mechanism in Ethernet passive optical networks (EPONs) for the optical network unit (ONU). It measures traffic loading continuously to identify traffic load for each ONU, then classifies such load to either a low or high loading level. The scheme allows ONU to transmit packets only when the system stays in high load conditions, otherwise ONU changes to one of power saving modes. Therefore, ONU can accumulate queued packets in low-load scenario and stay in power saving mode for longer duration. However, in order to avoid long queueing delay of high priority packets, the ONU will not switch to power saving mode, if the queue of high priority packets is not empty. Comparing to a previous proposed tri-mode energy saving scheme which imposed strict restriction on ONU's staying in energy saving modes, the proposed scheme achieves energy saving improvement without suffering noticeable delay performance degradation.
