Adaptive IIR notch filters have been widely studied for many years. However, not many efforts have been made to pursue new algorithms which work better than the plain gradient algorithm but have a little increase in complexity. In this paper, we employ the gradient linearization, Taylor series expansion and calculus of variations to derive a memoryless nonlinear gradient function for a second-order adaptive IIR notch filter, which improves the estimation performance considerably. Theoretical expressions for the stability bounds on the step size parameter and the steady-state coefficient variance of the proposed algorithm using the memoryless nonlinear gradient function are also derived. Extensive simulations indicate the significant improvement that may be achieved using the new algorithm, and verify the closed-form analytical results.

The transition towards electric vehicles (EVs) is a pivotal response to mitigate environmental concerns and reduce reliance on fossil fuels. This survey-based research aims to provide comprehensive insights into the stance of EV users in Croatia on using EVs as assets for flexibility in operation. Users are surveyed about their EV characteristics and habits, emphasizing charging preferences and possible subsidizing. Because of their larger degree of freedom in operation, family home users are further surveyed about their attitude toward load management, investments for additional sources of electricity and flexibility in operation, and advanced electricity billing models to ensure greater savings. Results show a very conservative stance of users toward actions that deteriorate their comfort level. Further on, users that dwell in a family house are prone to investments if it can generate additional savings and maintain or even increase their comfort level. This survey provided valuable findings for researchers in modeling EVs as a flexible asset in energy management studies, especially in the emerging field of energy communities.

Resonant wireless power transfer (WPT) is gaining popularity as a solution for wireless powering of electronic devices in multi-user environment where operating frequency must be fixed. This paper proposed a simulation model for parallel-serial topology of WPT system. Simulation model is verified by experimental measurement and used to analyze the impact which receiver power and coupling coefficient between transmitter and receiver have on resonant frequency of the system. Three resonant frequencies have been identified which correspond with local efficiency maximums. Criteria for resonant frequency shift evaluation is defined and conducted analysis has shown that by keeping the coupling coefficient under 0.1, the relative resonant frequency shift will not exceed 0.5%.

The flexible job shop scheduling problem (FJSP) is a complex problem with significant applications in modern manufacturing. While various metainspired algorithms are widely used in FJSP, they of-ten converge to local optima, especially as the problem size increases. To overcome this, we propose an adaptive hybrid algorithm with three stages of 'explore-exploit-escape' (E3HA). In the first stage, we design a Simplified Variable Neighborhood Search (Sim-VNS) algorithm and introduce a Simplified Nopt1 Neighborhood for extensive exploration of solution spaces. In the second stage, we introduce the crossover operation from genetic algorithms to better exploit the elite solutions obtained in the first stage, and we also use mutation operations to improve the quality of regular solutions. Finally, in the third stage, we design a hybrid mechanism of Reverse Learning with Path Relinking (RLPR) and introduce a critical path neighborhood structure to increase the effectiveness of solutions in avoiding local optima and premature convergence. We perform ablation experiments to confirm the effectiveness of each stage of E3HA and test the algorithm on all BRdata and Fdata instances, comparing its performance to relevant existing state-of-the-art algorithms. The results show the effectiveness and stability of our algorithm for FJSP. © 2023 IEEE.

Quadratic assignment problems one of combinatorial optimization problems that pays to number of facilities to number of places. The objective is to minimize the cost. QAP is one of the degree of complexity of hard problems deterministic algorithms are able to solve smaller sample problem. Fast local search used to solve qap. but despite the wider space exploration. There are not certain views for better search. The objective is to provide a way to be able find a visual representation of the search space Which leads to reduced method efficiency and in cases where the distance between the points searched was a great gap as much as possible to find areas that are not searched and evaluated. The new proposed method is able to decrease average best answer fast local search algorithm from 0.65 percent to 0.26 percent and so will have a better exploration of space search. Review its performance based on standard test functions and compare it with fast local search algorithm represent quality and its advantage, provide good results in a wide range of issues permutation.

Resonant wireless power transfer offers high degree of freedom for the receiver positioning, but it also has higher restraints on the design of the receiver circuit. This paper discusses design considerations for the design of the receiver circuit for applications in mid-power range (10100 W) using resonant wireless power transfer system. Wireless power receiver circuit consists of three main sub-circuits: resonant tank, rectifier circuit and DC-DC converter. The impact of each sub-circuit is analyzed with respect to efficiency and overall performance of the receiver circuit. Results from the mathematical models and simulations are compared with measurements. The final design of the receiver circuit is implemented in LCD TV and evaluated through laboratory measurements.

In autonomous pruning, the robot must identify the branches that need to be removed to improve the health and shape of the tree. Furthermore, the robot needs depth information about these branches in order to successfully perform tool navigation and finally pruning. In this work, we provide the BRANCH dataset with 70 RGB-D images of pear trees before and after pruning, taken in the real environment from different viewpoints to cover the whole tree. Based on these images, we created point clouds and performed model reconstruction to obtain 3D models of the trees. After overlaying the models before and after pruning, we obtained the points of the pruned branches. Therefore, we also provide labeled point clouds of 52 trees in BRANCH that can be used for further machine learning.

In this paper we present a Pareto-optimal algorithm in bilateral automated negotiation where the negotiation is modeled by "split the pie" game and alternating-offer protocol. Pareto-optimality is the seminal condition in the bargaining problem which leads autonomous agents to the Nash-equilibrium. Generating Pareto-optimal offer in multi-issue bargaining is a computationally complex problem, specially, when autonomous agents have incomplete information about deadline, outside options and the opponent's preferences. Unfortunately, yet to date, there is no articulation that clearly describes an algorithm to generate offer in multi-issue negotiation with perfect information. To this end, we present the maximum greedy trade-offs (MGT) algorithm that generate offers at any aspiration-level in O(n) with assuming that the order of greedy choices is given, otherwise the complexity will be O(n bg n). We also provide analytical proof for the correctness of the maximum greedy trade-offs algorithm.

Short linewidth light lasers are essential for a wide range of applications, including quantum computing, spectroscopy, and sensing. Stimulated Brillouin scattering is an intriguing method for achieving extremely coherent light laser output. The demonstration of an unstable pulsed Brillouin erbium fiber laser (BFL) operating at kHz is shown here. The BFL works at 1550.1 nm, which is 0.09 nm higher than the Brillouin pump wavelength since the dispersion compensating fiber was pumped over the 24.77 mW threshold. It has an extreme power of 0.7 dBm, a side-mode suppression ratio of 29 dB, and a pump power of 59.12 mW at 980 nm. Due to the intrinsic instability in relaxation oscillation, which generates the nonlinear self-pulsing mechanism in the BEFL cavity, the BEFL produced a pulse train running at 200.9 kHz with a 24.77 mW pump. The pulse frequency was raised to 3.02 MHz. The pump power has been increased to 59.12 mW. Yet, as the pump power was raised further, more than one pulse was produced. This is the first example of generating kHz pulses in a BFL cavity. The laser system is straightforward, small, and all-fiber. These are the attempts of experimental work to realize the BFL with Q-switched multi-wavelength output using a specific length of DCF to generate the pulses. © 2023 IEEE.
