Agriculture plays a pivotal role in the economic development of South Asian and African nations. However, adverse climate changes and disease invasions threaten crop productivity annually. Early identification and management of crop diseases are crucial for mitigating these effects. Cassava, a significant crop in the Philippines and other regions, faces challenges from various diseases, necessitating advanced diagnostic methods. This study uses deep learning techniques, specifically Convolutional Neural Networks (CNNs), to identify cassava leaf diseases. Researchers employed the Squeezenet architecture due to its efficiency and suitability for deployment on mobile devices. Our model classified cassava leaf status into four categories: Healthy, CBB (Cassava Bacterial Blight), CPD (Cassava Phytoplasma Disease), and BLS (Bacterial Leaf Streak). Using a robust dataset, the model achieved a high overall accuracy of 92%. The confusion matrix indicated strong performance in identifying diseased leaves, though there were some misclassifications in the Healthy category. These findings demonstrate the potential of deep learning techniques in enhancing crop disease management. They offer a promising tool for farmers in developing nations to protect their crops and improve agricultural productivity.

Here, we present a distributed adaptive control scheme for cooperative tracking of a class of nonlinear multiagent systems with partially unknown dynamics. The agents should reach an agreement on a time-varying reference trajectory as their virtual leader. The approach combines the artificial potential functions method with robust control terms to reach an appropriate controller for each agent. The unknown dynamics of each agent is approximated by an adaptive fuzzy system, with adaptive laws derived from Lyapunov stability analysis. Theoretical analysis reveals that H-infinity performance criterion is satisfied and the effects of uncertainties are kept below a desired attenuation level. The proposed method is applied to the state tracking problem of five inverted pendulums. Results indicate the effectiveness of the proposed approach in handling noise and bounded uncertainties as well as reaching consensus with high precision.

Precision measurements by the Alpha Magnetic Spectrometer (AMS) on the International Space Station of He3 and He4 fluxes are presented. The measurements are based on 100 million He4 nuclei in the rigidity range from 2.1 to 21 GV and 18 million He3 from 1.9 to 15 GV collected from May 2011 to November 2017. We observed that the He3 and He4 fluxes exhibit nearly identical variations with time. The relative magnitude of the variations decreases with increasing rigidity. The rigidity dependence of the He3/He4 flux ratio is measured for the first time. Below 4 GV, the He3/He4 flux ratio was found to have a significant long-term time dependence. Above 4 GV, the He3/He4 flux ratio was found to be time independent, and its rigidity dependence is well described by a single power law ∝RΔ with Δ=−0.294±0.004. Unexpectedly, this value is in agreement with the B/O and B/C spectral indices at high energies.

advanced control methods for industrial process control

computing & control ENGINEERING JOURNAL 2004年第3期15卷 18-23页

作者： Airikka, P Timberjack Finland

advanced control methods involve more complex calculations than the conventional PID controller algorithm. Often, advanced control is a high-level control procedure that takes care of sub-processes controlling low- level unit control loops such as PID controllers. In this case, advanced control strategy aims to fulfill economic objectives by providing appropriate set points for the lower-level control loops to minimize a given performance criterion. The use of process models is a common characteristic for advanced control methods. advanced control relies strongly on process models that describe the process behavior. The models try to capture the essence of the process information. We give an overview of the seven advanced control method: adaptive control, multivariable control, model predictive control, fuzzy control, robust control, neural network based control and optimal control.

This paper deals with the direct torque control of high voltage / high power induction motors fed by floating capacitor multilevel VSI actuators. The active control strategy for well-balancing the capacitor voltages is presented highlighting an optimal pattern. The efficiency of this approach is compared to the well-known passive method and it is illustrated by simulation. In the next section, a controlled cycle based algorithm is proposed as an attractive solution for a high performance torque control satisfying a constant switching frequency required by IGBT. Associated simulation results show the good behaviour of this algorithm.

International Conference on Simulation

The HIPERTRANS (high performance Transport Network Modelling and Simulation) project is developing a simulation tool that will provide a new range of facilities for road transport consultants, traffic engineers and urban traffic control centre (UTC) managers. Through the application of a low cost but high performance computing environment, advanced simulation technologies and industrial software production methodologies, a fast, representative, flexible and visually comprehensive traffic simulation tool is available. This tool will have a major impact on the work of road traffic consultants and policy makers who will be able to rapidly assess and visualise the effects of new strategies and policies in the management and planning of urban road networks. The activities of traffic engineers in developing new control paradigms can be enhanced and supported by the simulator's ability to link to a UTC in real-time and behave in the same way as a specified road network. This will allow street conditions to be examined when controlled by different strategies or algorithm settings and the different results compared. This paper provides the concept and results of the work achieved in the project that has ascertained users requirements converted into a technical design. The requirements for the HIPERTRANS simulation and prediction tool have been analysed to produce a specification of the system. The specification has formed the basis for a detailed system design. The design is being implemented to deliver three versions of the HIPERTRANS system: the prototype simulator, S1;the real-time simulator, S2;and the predictor, S3. The simulators are targeted towards testing of traffic control systems by stimulating them with a wide range of potential traffic scenarios in order to safely evaluate their behaviour.

iee colloquium on high performance Architectures for Real-Time Image Processing

作者： T.M. Sheen A.R. Allen A.E. Lawrence I. Page Department of Engineering University of Aberdeen UK The Computing Laboratory University of Oxford UK

There are an increasing number of applications of automated image analysis in which imaging is part of an instrumentation or process control system. A variety of industrial processes, including quality control and assembly, robotic, security and other applications make use of machine vision. Such embedded applications often require performance to be tuned in various ways to satisfy time constraints, which may vary through the lifetime of the application. There may, in addition, be a requirement to produce versions of an imaging product targetted at different classes of user, to satisfy various market niches, for example. It is therefore important to develop software tools which allow developers to relatively easily target a variety of computational engines. Possible target systems may include PC, dedicated microprocessor or digital signal processor, multiprocessors, or custom hardware. We report our experience in applying hardware compilation technology in an FPGA-based system to some typical image processing tasks.
