- Technological modernization and innovation of traditional agri‐food companies based on ICT solutionsPublication . Gaspar, Pedro Dinis; Soares, Vasco N. G. J.; Caldeira, João; Andrade, Luís P.; Soares, Cláudia D.This paper assesses the potential for technological modernization and innovation based on Information and Communication Technologies (ICT) in traditional agri‐food companies located in the central region of Portugal. A survey was applied to 50 agri‐food companies of cereals, cheese, olive oil, dry sausages, honey, wine, and horticultural sectors. Results analysis show that companies use computers, have internet service, and use social networks for business purposes. However, most of it have no webpage, do not use internet for advertising/selling/buying products, and have not promoted collaborators’ ICT training. Companies expect webpages to improve their productivity and/or marketing products/services. Recommendations were provided to promote the use of ICT for business purposes. Webpages, Facebook pages, and CRM systems were developed to a limited set of companies. The results of the satisfaction survey of the ICT solution confirm the company sales increase due to the web visibility gained by the company products.

- Wireless Sensor Networks for Building Robotic Paths - A Survey of Problems and RestrictionsPublication . Amaro, José P. A.; Caldeira, João; Soares, Vasco N. G. J.; Gaspar, Pedro DinisThe conjugation of small nodes with sensing, communication and processing capabilities allows for the creation of wireless sensor networks (WSNs). These networks can be deployed to measure a very wide range of environmental phenomena and send data from remote locations back to users. They offer new and exciting possibilities for applications and research. This paper presents the background of WSNs by firstly exploring the different fields applications, with examples for each of these fields, then the challenges faced by these networks in areas such as energy-efficiency, node localization, node deployment, limited storage and routing. It aims at explaining each issue and giving solutions that have been proposed in the research literature. Finally, the paper proposes a practical scenario of deploying a WSN by autonomous robot path construction. The requirements for such a scenario and the open issues that can be tackled by it are exposed, namely the issues of associated with measuring RSSI, the degree of autonomy of the robot and connectivity restoration.

- Detection of Waste Containers Using Computer VisionPublication . Valente, Miguel; Silva, Hélio; Caldeira, João; Soares, Vasco N. G. J.; Gaspar, Pedro DinisThis work is a part of an ongoing study to substitute the identification of waste containers via radio-frequency identification. The purpose of this paper is to propose a method of identification based on computer vision that performs detection using images, video, or real-time video capture to identify different types of waste containers. Compared to the current method of identification, this approach is more agile and does not require as many resources. Two approaches are employed, one using feature detectors/descriptors and other using convolutional neural networks. The former used a vector of locally aggregated descriptors (VLAD); however, it failed to accomplish what was desired. The latter used you only look once (YOLO), a convolutional neural network, and reached an accuracy in the range of 90%, meaning that it correctly identified and classified 90% of the pictures used on the test set.

- Development of Technological Capabilities through the Internet of Things (IoT): Survey of Opportunities and Barriers for IoT Implementation in Portugal’s Agro-IndustryPublication . Gaspar, Pedro Dinis; Fernandez, Carlos M.; Soares, Vasco N. G. J.; Caldeira, João; Silva, HélioThe agro-industrial sector consumes a significant amount of natural resources for farming and meat production. By 2050, population growth is expected, generating more demand and, consequently, more consumption of scarce resources. This challenging scenario is a concern of the European Commission, revealed in the Green Deal commitment and by the United Nations’ 12th goal of sustainable development. Thus, organizations must increase productivity and be more sustainable as soon as possible. Internet of Things (IoT) is introduced as a solution to facilitate agro-food companies to be more eco-efficient, mainly facing difficulties on farms, such as food loss and waste, best efficiency in management of resources, and production. The deployment of this technology depends on the stage of maturity and potential of implementation. To assess and characterize companies, with respect of IoT implementation, a survey was applied in 21 micro, small and medium agro-food companies, belonging to milk, honey, olive oil, jams, fruticulture, bakery and pastry, meat, coffee, and wine sectors, in the central region of Portugal. As results, this paper reveals the stage of maturity, level of sophistication, potential, opportunities, solutions, and barriers for implementation of IoT. Additionally, suggestions and recommendations to improve practices are discussed.
