Crop diseases disrupt the crop's physiological constitution by affecting the crop's natural state. The physical recognition of the symptoms of the various diseases has largely been used to diagnose cassava infections. Every disease has a distinct set of symptoms that can be used to identify it. Early detection through physical identification, however, is quite difficult for a vast crop field. The use of electronic tools for illness identification then becomes necessary to promote early disease detection and control. Convolutional neural networks (CNN) were investigated in this study for the electronic identification and categorization of photographs of cassava leaves. For feature extraction and classification, the study used databases of cassava images and a deep convolutional neural network model. The methodology of this study retrained the models' current weights for visual geometry group (VGG-16), VGG-19, SqueezeNet, and MobileNet. Accuracy, loss, model complexity, and training time were all taken into consideration when evaluating how well the final layer of CNN models performed when trained on the new cassava image datasets.

This research developed a modification to the Grid Accounting Scheme (GridBank) by formulating a model to enhance the scheme. The enhanced scheme was simulated and its performance was evaluated. Thiswas done with a view to eliminating the manual mode of processing as well as speed up transactions and reduce time delay. The PayPal layer was added to the existing three layers which enhanced the scheme to allow for the automation of the GridBank administration module. The enhanced scheme was formulated using the web service approach that allowed cross platform interoperability. The results of the simulation showed that as the number of users increased, the processing time gradually reduced for the enhanced scheme which made its processing delay to be reduced. Also as the number of available resources increased the enhanced scheme scaled the load properly. These showed improvements over the existing scheme. It was concluded that the enhanced accounting scheme provided the required automation for efficient and secure grid accounting operations.

Accessing the advantages of cloud computing requires that a prospective user has proper access to trustworthy cloud services. It is a strenuous and laborious task to find resources and services in a heterogeneous network such as cloud environment. The cloud computing paradigm being a form of distributed system with a complex collection of computing resources from different domains with different regulatory policies but having a lot of values could enhance the mode of computing. However, a monolithic approach to cloud service discovery cannot help the necessities of cloud environment efficiently. This study put forward a distributive approach for finding sincere cloud services with the use of Multi-Agents System for ensuring intelligent cloud service discovery from trusted providers. Experiments were carried out in the study using CloudAnalyst and the results indicated that extending the frontiers MAS approach into cloud service discovery by way of integrating trust into the process improves the quality of service in respect of response time and scalability. A further comparative analysis of the Multi-Agents System approach for cloud service discovery to monolithic approach showed that Multi-Agents System approach is highly efficient, and highly flexible for trustworthy cloud service discovery.
