The world is currently experiencing population explosion, and it has been forecast that the population would reach nine billion by the year 2050. This rapid population growth is accompanied with new challenges, including high demand for food supply, which may lead to food crises. Contemporary agricultural methods and resources cannot meet the forecast food demand. Precision agriculture is one of the best ways to meet this demand, and using agricultural robots is an important aspect of it. Many researchers have been conducting studies on the application of robots in agricultural tasks such as farm clearance, seeding, seedling, spraying, fertilization, and harvesting. This paper presents a comprehensive review on path planning techniques for agricultural robots. it focuses on different types of agricultural robots and path plans in use. It also provides taxonomy of agricultural robot path plans, metadata analysis, and deep insights into the recent developments in the research area, while pointing out the challenges being faced and possible future solutions. This article may serve as a guide to early career researchers with interest in agricultural robots to easily understand the current developments and the future research focus in this field. © 2022 IEEE.

To study the design problem of robust reliable guaranteed cost controller for nonlinear singular stochastic systems, the Takagi-Sugeno （T-S） fuzzy model is used to represent a nonlinear singular stochastic system with norm-bounded parameter uncertainties and time delay. Based on the linear matrix inequality （LMI） techniques and stability theory of stochastic differential equations, a stochastic Lyapunov function method is adopted to design a state feedback fuzzy controller. The resulting closed-loop fuzzy system is robustly reliable stochastically stable, and the corresponding quadratic cost function is guaranteed to be no more than a certain upper bound for all admissible uncertainties, as well as different actuator fault cases. A sufficient condition of existence and design method of robust reliable guaranteed cost controller is presented. Finally, a numerical simulation is given to illustrate the effectiveness of the proposed method.

An adaptive target queue length (ATQL) adjustment algorithm proposed in this paper cooperates with certain Active Queue Management (AQM) controllers to achieve more efficient buffer management for Internet congestion control. ATQL algorithm which estimates the average traffic load and dynamically adjusts the target queue length in dynamic traffic environment can be easily embedded into a series of AQM controllers. By engaging ATQL, AQM controllers are more suited to random and unpredictable traffic scenarios. Simulations are applied to validate ATQL's ability in assisting AQM controllers in sustaining stable drop probability, minimizing unnecessary packet loss, guaranteeing the link utility and maximizing the exploitation of buffer spaces.

Since congestion of traffic is ubiquitous in the modern city, optimizing the behavior of traffic lights for efficient traffic flow is a critically important goal. However,agents often select only locally optimal actions without coordinating their neighbor intersections. In this paper, an urban road traffic area-wide coordination control algorithm based on collaborative Q-learning is proposed. The agent model of traffic intersections is demonstrated. The algorithm substantially reduces average vehicular delay by using a collaborative Q-learning algorithm and can cooperative control of multiple intersections to achieve a near optimal control policy. The computer simulation results show that the control algorithm can effectively reduce the average delay time and play a very good control effect with multi-intersections, so the coordination method used in this paper is effective. © 2011 IEEE.

Traffic congestion is ubiquitous in the modern city, and optimizing the behavior of traffic lights for efficient traffic flow is a critically important goal. In this paper, an urban road traffic area-wide coordination control algorithm based on Approximation Dynamic Programming is proposed. The agent model of traffic intersections is demonstrated. The algorithm substantially reduces average vehicular delay by using an approximation to the value function of the dynamic programming to update the approximation, and can cooperative control of multiple intersections to achieve a near optimal control policy. The computer simulation results show that the control algorithm can effectively reduce the average delay time and play a very good control effect with multi-intersections, so the coordination method used in this paper is effective. ©2010 IEEE.

For the fault diagnosis of three-phase induction motors, we set up an experimental unit and then develop a diagnosis algorithm based on pattern recognition. The experimental unit consists of induction motor drive and data acquisition module to obtain the fault signals. As the first step for diagnosis procedure, preprocessing is performed to make the acquired current simplified and normalized. To simplify the input data, three-phase currents are transformed into the magnitude of Concordia vector. As the next step, feature extraction is performed by kernel PCA. Finally, we used the linear classifier based on two types of distance measures. To show the effectiveness, the proposed fault diagnostic system has been intensively tested with the various data acquired under the different electrical and mechanical faults with varying load. © Springer-Verlag Berlin Heidelberg 2006.

Genetic instability is one of the hallmarks of cancer, however mutations can occur for different causes and induce different effects. Mutational signatures are characteristic patterns of somatic mutations in cancer genomes, reflecting the underlying mutational processes. A mutational signature can be determined by studying the kind of mutations a patient has acquired during their life: patient stratification based on mutational signatures has become more and more useful in genomic studies, given its possible clinical implications. In this work we focused on Single Base Substitution (SBS) signatures to study a cohort of 115 metastatic melanoma patients. We inferred and identified two mutational signatures characterizing the patients. Based on these signatures we divided patients into two group: the bigger group was characterized by a signature associated with exposure to ultraviolet light, while the smaller group resulted to be mostly composed of patients which did not respond to immunotherapy (anti-PD1) and that presented a low mutational count. More importantly this second group showed a significantly worse survival outcome. The use of mutational signatures is clearly a powerful tool to identify disease sub-types that have a clinical relevance, however we believe that this topic needs further investigation focused on the characterization of patient subtypes with a multi-omics based approach. © 2023 IEEE.

A processes composed of sequences of local cyclic The theoretical prediction of the behavioral properties of periodic structures is less difficult than in the case of nonperiodic ones. That is because all the information needed to describe the entire structure is given by the elementary substructure itself and by the manner it repeats in the whole periodic structure. So, only a small portion of the structure (which includes the repeating substructure) needs to be considered to obtain the properties of the whole periodic structure. In that context, the contribution provides the discussion of some system periodicity issues, and is aimed at modeling and evaluation of relationships linking the system structure features with required system's functioning. © 2013 IEEE.
