With the gradual development of intelligent logistics and multi-AGV (Automatic Guided Vehicle) systems, the application of automated warehouses is becoming more and more extensive. Among them, the path planning of AGVs is often a huge challenge. Under the specific constraints of road layout, the path planning methods described in the existing literature are often not good at avoiding congestion. In this paper, according to the limits of narrow lanes, we propose a path planning algorithm for predicting congestion. This algorithm is an improvement of the A-star algorithm, which introduces the current congestion cost and future congestion cost, and can plan the path to avoid the congested area, reduce the probability of runtime conflicts. Through simulation comparison, it is verified that the proposed algorithm has a good application prospect in alleviating traffic congestion.

This paper investigates the problem of horizontal path-following control for parafoil systems with error constraint. Frist, by introducing the guidance theory, the horizontal position control is converted to the control of the azimuth angle of the parafoil system. The error signal of the angle is transformed to a new error variable, such that the error is constrained into the prescribed boundaries. Next, the methods of backstepping and output feedback are employed in the controller design. The uncertainties in parafoil system modeling and external disturbances are estimated using the lineaer extended state observer (LESO). The stability analysis based on Lyapunov method shows that all the error signals are uniformly ultimately bounded. Simulation results of a 6 degree-of-freedom parafoil system illustrate the effectiveness of the proposed method.

Signature of a person can uniquely identify the person and it is widely used in social situations and monetary transactions with individuals and financial entities. Many fraud cases have been appearing in society where signature of a person is forged for financial and other benefits. There is need for detecting forged signatures with technology driven approaches. With the emergence of Artificial Intelligence (AI), there are unprecedented possibilities in solving problems of the real world with responsible usage of AI. Deep learning (DL) is one part of AI which extends neural networks has become very significant in computer vision applications. From the existing approaches, it is observed that there is need for a complete framework for end to end processing of signatures for efficient detection of forgeries. Towards this end, we proposed a DL based framework for automatic detection of signature forgery. This study has proposed an algorithm known as Learning based Signature Forgery Detection (LbSFD), which exploits pipeline of multiple DL models such as CNN, VGG16 and Siamese. All the models are CNN variants used to improve efficiency in signature forgery detection. A benchmark signature dataset is used for our empirical study. Our experiments revealed that the CNN based models are highly efficient in signature forgery detection. Highest accuracy with 98.26% is achieved when VGG16 model is employed with transfer learning.

Dynamic wireless charging (DWC) is an emerging technology designed to enable electric vehicles (EVs) to be wirelessly charged while in motion. It is gaining significant momentum as it can potentially address the limited range problem for EVs. However, due to the significant power loss caused by wireless power transfer, improving the charging efficiency remains as a major challenge. This paper presents the first Long Short-Term Memory (LSTM)-based EV motion control system for DWC with an aim to maximize the charging efficiency. The dynamics of the electromagnetic field generated from the transmitter coils of a DWC system are effectively captured using a machine-learning approach based on the multi-layer LSTM. The multi-layer LSTM model is used to predict the location where the electromagnetic strength is expected to be maximal and to control the lateral position of EV accordingly to optimize the charging efficiency. Extensive simulations were conducted to demonstrate that our LSTM-based EV motion control system achieves by up to 174% higher charging efficiency compared with existing vehicle motion controlsystems focused on keeping an EV in the center of the lane.
