A Binary Adaptive Clone Shuffled Frog Leaping Algorithm for Three-Dimensional Low-Energy Target Coverage Optimization in Environmental Monitoring Wireless Sensor Networks

In recent years, more and more researchers have paid attention to the three-dimensional target coverage of environmental monitoring wireless sensor networks (EMWSNs) under real environmental conditions. However, the target coverage method studied in the traditional two-dimensional plane is full of loopholes when applied in the real three-dimensional physical world. Most coverage algorithms usually only optimize for a single problem of target coverage or network energy consumption and cannot reduce network energy consumption while improving coverage. This paper proposes a novel binary adaptive clone shuffled leapfrog algorithm (BACSFLA) suitable for EMWSNs. BACSFLA has an excellent performance in the coverage of three-dimensional nodes, which can significantly reduce the network energy consumption of ENWSNs in the coverage process, and greatly improve the coverage of nodes. Through simulation experiments, BACSFLA was compared with simulated annealing (SA) and genetic algorithm (GA) in the same conditional parameters. The coverage rate of BACSFLA in EMWSNs is 3.9 % higher than that of GA and 5.4 % higher than that of SA. The network energy consumption of BACSFLA is 36.0 % lower than GA and 35.9 % lower than SA. Moreover, BACSFLA can significantly reduce the calculation time and get better results in a shorter time.

Implementation of a Novel Remote Physician SBRT Coverage Process during the Coronavirus Pandemic

INTRODUCTIONDuring the COVID-19 pandemic, alternative methods of care are needed to reduce the relative risk of transmission in departments. Also needed is the ability to provide vital radiation oncological care if radiation oncologists (RO) are reallocated to other departments. We implemented a novel remote RO SBRT coverage practice, requiring it to be reliable, of high audio and visual quality, timely, and the same level of specialty care as our current in-person treatment coverage practice.METHODSAll observed failure modes were recorded during implementation over the first 15 sequential fractions. The time from CBCT to treatment was calculated before and after implementation to determine timeliness of remote coverage. Image quality metrics were calculated between the imaging console screen and the RO’s shared screen. Comfort levels with audio/visual communication as well as overall comfort in comparison to in-person RO coverage was evaluated using Likert scale surveys after treatment.RESULTSRemote RO SBRT coverage was successfully implemented in 14/15 fractions with 3 observed process failures that were all corrected before treatment. Average times of pre-treatment coverage before and after implementation were 8.74 and 8.51min, respectively. The cross correlation between the imaging console screen and RO’s shared screen was r=0.96 and lag was 0.05s. The average value for all survey questions was above 4.5, approaching in-person RO coverage comfort levels.CONCLUSIONSOur novel method of remote RO SBRT coverage permits reduced personnel and patient interactions surrounding RT procedures. This may help to reduce transmission of COVID-19 in our department and provides a means for SBRT coverage if ROs are reallocated to other areas of the hospital for COVID-19 support.

PROSES PELIPUTAN BERITA “LINTAS PAGI” RRI SEMARANG DALAM PERSPEKTIF KOMUNIKASI ISLAMI

<p><em>Radio is an auditive communication media with several characteristics, among them is a crosshairs and contain interference. Listening to radio programs can only be done once. One of the radio programs is news. Dissemination of information and news via radio can take place quickly and wider. Broadcast news on the radio must be true, once the news is wrong in broadcast it is not possible to repeat again. Because the listener may only hear the error, do not hear what is rectified. It may also be that the listener did not hear the error, so that the wrong message rectified is correct. In the context of Islamic communication spreading good, true, and honest news is a must. Islamic communication is a way of communicating that is Islamic, which is not contrary to the teachings of the Qur'an and Hadith.</em></p><p><em>This study aims to describe the news coverage process "Lintas Pagi" RRI Semarang in the perspective of islamic communication.

Multiscale volatility duration characteristics on financial multi-continuum percolation dynamics

A random stock price model based on the multi-continuum percolation system is developed to investigate the nonlinear dynamics of stock price volatility duration, in an attempt to explain various statistical facts found in financial data, and have a deeper understanding of mechanisms in the financial market. The continuum percolation system is usually referred to be a random coverage process or a Boolean model, it is a member of a class of statistical physics systems. In this paper, the multi-continuum percolation (with different values of radius) is employed to model and reproduce the dispersal of information among the investors. To testify the rationality of the proposed model, the nonlinear analyses of return volatility duration series are preformed by multifractal detrending moving average analysis and Zipf analysis. The comparison empirical results indicate the similar nonlinear behaviors for the proposed model and the actual Chinese stock market.

Complete Coverage Path Planning for Flexible Parent-Child Unit Robots

This paper presents a complete coverage algorithm for a flexible parent child unit robot by combining input shaping with the wavefront algorithm. Input shaping was used to control the command-induced vibration in the system, while the wavefront algorithm planned the complete coverage path for a given workspace. A model of the flexible robot was developed by treating the child units as inputs, replacing the link wire by springs and dampers, and treating the parent unit as a point mass. Results showed significant improvement in the coverage process for the shaped coverage in comparison to the unshaped coverage.
