Summary: With the increasing adoption of distributed energy resources (DERs) in distribution networks, it has become more necessary to coordinate and control them using a DER management system (DERMS) that provides grid services. A new type of DERMS using primal-dual control has been found to be effective in providing multiple grid services; however, the main parameter, the primal-dual step size, needs to be manually tuned for the DERMS to be effective. In this study, we propose a simple method that automatically tunes the step size(s) and adapts it to changing system conditions. The evaluation results show that the DERMS with automatically tuned step sizes provides higher-quality grid services than a DERMS with manually tuned step sizes.

Summary: In this paper, an adaptive multi-agent system with duplex control laws is proposed for solving the non-smooth resource allocation problem. The system, based on the distance penalty function method, is developed using coupled differential equations or inclusions, with the last set of equations used to learn an adaptive penalty vector. Proportional and integral controls can be performed from different layers of the multiplex control network, each having its own communication topology. The existence of equilibrium points and convergence of the system are proven, enabling optimal resource allocation from any initial allocation. The simulation results of two illustrative examples are discussed to validate the theoretical findings.

Summary: An adaptive fault-tolerant control scheme is proposed for nonlinear systems with actuator redundancy in this article. The L-1 adaptive control scheme for nonlinear time-varying reference systems is extended to systems with redundant inputs, and a fixed, predictable control allocation is achieved through a feedback loop. Increasing the adaptation rate and the feedback gain can improve the performance bounds of the system relative to the ideal system.

Summary: Deer are critical components of many ecosystems, and accurately estimating deer abundance and density is crucial for understanding their roles. This study systematically reviewed journal articles published from 2004 to 2018 to evaluate trends in study objectives, methodologies, and abundance and density estimates, as well as their variations with biophysical and anthropogenic attributes. The findings highlight the need for reporting methodological details, robustly assessing bias, reporting precision, using methods that increase detection probability, and staying up to date on new methods to improve the usefulness of deer abundance and density estimates.

Summary: Introduced sambar deer in south-eastern Australia are being controlled using volunteer and contract ground-based shooters, but little is known about their effectiveness and costs. This study evaluated the effectiveness and costs of both shooter types in controlling sambar deer in and around alpine peatlands in Alpine National Park, Victoria. The catch per unit effort of contract shooters was four times greater than that of volunteer shooters, but the cost per deer killed was slightly higher for contract shooters.

Summary: The animal welfare outcomes of helicopter-based shooting of deer in Australia were evaluated by quantifying the fates of deer seen and shot at, the duration of procedures, and the number and location of bullet wounds in deer. The results showed that animal welfare outcomes were better in the two fallow deer operations than in the chital deer operation. The best outcomes were achieved when multiple shots were fired into each animal and the helicopters flew back over shot animals.
