Recent development in deep learning, particularly transfer learning, is gaining a preferred trend of research in medical image processing because of their admirable performance, even with small datasets. It inspires us to develop a novel deep learning-based leukemia detection system in which an efficient and lightweight MobileNetV2 is used in conjunction with ShuffleNet to boost discrimination ability and enhance the receptive field via convolution layer succession. More importantly, the suggested weight factor and an optimal threshold value (which is experimentally selected) is responsible for maintaining a healthy balance between computational efficiency and classification performance. Hence, the benefits of inverted residual bottleneck structure, depthwise separable convolution, tunable hyperparameters, pointwise group convolution, and channel shuffling are integrated to improve the feature discrimination ability and make the proposed system faster and more accurate.

One of the main measurement challenges is the communication delay. It means the delay in sending data from the sensor or measuring unit to the processing unit. The communication delay gets more important when the microgrid is widespread and complex. In this paper, a novel soft switching voltage control system is proposed to solve the voltage control problem of a widespread micro-grid while there are time-varying communication delays.

The paper addresses two new key issues regarding AGV systems. First, it examines the diagnosis problem of automated transport systems from a discrete-event systems perspective. Secondly, it presents a control architecture enhanced with a diagnostic layer to improve fault tolerance. The theory of automata and languages is used to address control and diagnostic issues. The proposed methodology offers a systematic approach to design specification and diagnostic automata for routes shared by AGVs. The new specification automata integrate information from the diagnostic automata via synchronized transition guards, guaranteeing the synthesis of a robust supervisor that avoids deadlocks even when observability is compromised.

In view of this, this paper proposes a mode switching controller based on an IMS. First, the K-filters theory is innovatively applied to the mode switching hydraulic system to estimate unmeasurable state variables of a system accurately. In addition, fuzzy logic systems (FLSs) are applied to handle the unmodeled errors and disturbances in the mechanical system dynamics model and hydraulic system. Further, aiming at the stability and trajectory tracking problems in the mode switching control (MSC) process of an IMS, the average dwell time (ADT) stability analysis method is applied to the mode switching hydraulic system to construct a set of switching rules to make the closed-loop switching system stable. Moreover, based on the prescribed performance control (PPC) theory, all state errors of a hydraulic system are guaranteed to reach the performance function constraint boundary at the specified time. Also, a dynamic surface control (DSC) technique is used to avoid the explosion of computational complexity caused by iterative differentiation inherent in the traditional backstepping method. Finally, the feasibility and effectiveness of the proposed method are verified by simulation, and experiments are carried out on mini-excavators.
