Streszczenie:

This paper proposes a novel interval intersection-based protocol for time coordination in wireless sensor and IoT networks. The common notion of time amid the nodes in a distributed environment can be achieved through the message exchange process, which experiences random delay (send, access, propagation, and reception), thus making the time coordination process difficult. Several researchers have proposed algorithms to handle the error in estimation using various methods. This paper analytically analyzes the proposed novel unidirectional interval intersection method for mitigating the uncerta

Pantry Feeder reconfiguration at the Cipinang substation requires readjusting its relay parameters so it can work fast, selectively, and sensitively. The conventional relay parameter calculation method requires a manually iterative process, which may result in inaccuracy. To avoid this error, the parameters of the main relay (Relay CBO E146) and the backup relay (Relay Incoming Feeder) at the Pantry Feeder are set using the metaheuristic method, in this case the Firefly Algorithm. This algorithm's goal is to find the shortest relay coordination time given the relay working time limits and coor

Estimating a time interval and temporally coordinating movements in space are fundamental skills, but the relationships between these different forms of timing, and the neural processes that they incur, are not well understood. While different theories have been proposed to account for time perception, time estimation, and the temporal patterns of coordination, there are no general mechanisms which unify these various timing skills. This study considers whether a model of perceptuo-motor timing, the τGUIDE, can also describe how certain judgements of elapsed time are made. To evaluate this, an

Relay coordination optimization issues are multi-objective, multi-constrained problems that aim to reduce each relay's operation time while satisfying all relevant constraints. Fulfillment of the coordination time interval (CTI) and time limitations for relay operations are the coordination constraints. To solve coordination optimization issues, decision-making variables are defined such that the objective function is minimized with due satisfaction of necessary constraints.

107 Background: UNEME-DEDICAM (UD) clinics are part of a national public health initiative to provide women prompt access to cervical and breast cancer (BC) screening and diagnosis. Furthermore, UD clinics play a central role in the coordination and prioritization of patient transfer to treatment-specialized institutions. To facilitate this process, we planned and implemented an interinstitutional virtual multidisciplinary tumor board (VMDT). Herein, we present our current experience. Methods: We planned and implemented our VMDT in September 2020. Weekly sessions were established for the multi

Team situation awareness (SA) has not received the same amount of research attention as individual SA. Given a lack of established relationships between objective and perceived measures of teamwork, as well as between team psychophysiology and perceived teamwork, the present study examined these potential relationships during a two-person, continuous tracking task. Seventeen two-person teams of undergraduates performed a computer-based, simulated teleoperation task. This investigation tested for relationships between objective performance measures (task completion time, team tracking error, co

Abstract Avian duets are formed when 2 birds coordinate their songs. Most research on the evolution and function of duetting has focused on species with highly coordinated duets, and less is known about the context and function of overlapping songs that are more loosely coordinated, in part due to the challenge of determining whether such vocalizations coincide by chance or through coordination between the partners. Here, we use field recordings and playback experiments to test whether breeding pairs of superb fairy-wrens, Malurus cyaneus, coordinate their territorial songs to form duets. We t

Polarization navigation is an emerging navigation technology, that exhibits significant advantages, including strong anti-interference capability and non-cumulative errors over time, making it highly promising for applications in aerospace, autonomous driving, and robotics. To address the requirements of high integration and low power consumption for tri-directional polarization navigation sensors, this study proposes a system-on-chip (SoC) design solution. The system employs the ZYNQ MPSoC (Xilinx Inc., San Jose, CA, USA) as its core, leveraging hardware acceleration on the Programmable Logic

In the proposed protection coordination scheme, the depreciation of the operation time of the entire relay in the primary and backup protection modes for all possible fault locations is considered as the objective function. The limitations of this problem include the equations for calculating the operation time of the relays in both forward and reverse directions, the limitation of the coordination time interval, the limitation of the setting parameters of the proposed relays, the restriction of the size of the reactance that limits the fault current, and the limitation of the standing time of

BACKGROUND: Swallowing coordination is affected by cortical and subcortical inputs from the central nervous system. Our hypothesis is that the swallowing dynamics may be influenced by gender.

A hypothesis is formulated and substantiated that quasi-static deformation in an amorphous metal alloy is a complex relaxation multi-stage process, which is a hierarchical sequence of interrelated structural transitions of the first order ordered in time. These nonequilibrium processes sequentially proceed at different scale space-time levels, starting from the lowest level --- a cluster of atoms of the first coordination sphere with a relaxation time taueta, then the middle level - a nanocluster of atoms of the fifth coordination sphere with a relaxation time tauφ, spatial scale of 10 nm and

Furthermore, some practical constraints, such as the time-varying capacity of each airport, waypoints affected by factors such as weather and traffic control, and maximum delay tim

This paper proposes a robust hybrid-MAC protocol for direct communication among M2M devices with gateway coordination. The proposed protocol combines the benefits of both contention-based and reservation-based MAC schemes. The authors assume that the contention and reservation portion of M2M devices is a frame structure, which is comprised of two sections: Contention Interval (CI) and Transmission Interval (TI). The CI is based on p-persistent CSMA mechanism, which allows M2M devices to compete for the transmission slots with equal priorities. After contention, only those devices, which have w
