The cloud computing space is enjoying a renaissance. Not long ago, cloud computing was confined to the wall of high-revenue companies, but in recent times a growing number of businesses, public and private institutions are turning to the cloud computing platform to reap the benefits of a self-service, scalable, and flexible infrastructure. Moreover, with the increased implementation, advantages, and popularity of artificial intelligence, the demand for computing environments to solve age-old problems such as malaria and cancer is on the rise. This paper presents the implementation of a cloud computing infrastructure, the FEDerated GENomics (FEDGEN) Testbed, to provide an adequate IT environment for cancer and malaria researchers. The cloud computing environment is built using Openstack middleware. OpenStack is deployed using Metal-As-A-Service (MAAS) and Juju. Virtual Machines (Instances) were deployed, and services (JupiterHub) were installed on the FEDGEN testbed. The built infrastructure would allow the running of models requiring high computing power and would allow for collaboration among teams.
Achieving United Nations Sustainable Development Goal 2 (UN SDG2) infers an imperative to urgently increase food production by up to 70%. However, concerns have risen that increases in food production have not kept pace with increase in world population, which is estimated to reach 10 billion people by the year 2050. In this paper, an IoT with machine learning based system was developed to acquire and process significant indicators such as temperature, moisture, humidity and leave images for the detection of Sigatoka disease in plantain. Appropriate sensors for detecting the stated disease indicators were interfaced with Raspberry Pi3 microcontroller module to collate and transmit the sensor data wirelessly to ThingSpeak, which is the selected cloud based IoT platform. The acquired leave images were further processed using two image descriptors, namely: Scalable Color Descriptor (SCD) and Histogram of Oriented Gradient (HOG) to extract discriminative color and texture features respectively. The features were then classified to detect the diseased or non-diseased class using Multilayer PerceptronArtificial Neural Network (MLP-ANN). The best accuracy of 98% was produced using the HOG descriptor.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
