Industry Members' Perceptions about ABET-based Accreditation: An Exploratory Study in a Developing Country

ABET accreditation is an increasingly prominent system of global accreditation of engineering programs, and the assessment requires programs to demonstrate that they meet the needs of the program's stakeholders, typically industrial potential employers of graduates. To obtain these inputs, programs are required to assemble an advisory committee board. The views of the advisory board on the relevance of the degree outcomes are an essential part of this process. The purpose of this qualitative research study is to explore the viewpoints that industry stakeholders have on this type of process. The context for the study was an Ecuadorian engineering program which had successfully achieved the ABET accreditation. The study drew on interviews undertaken with industry members who were part of the advisory board. This study focuses on how they perceive the process and the accreditation awarded, analyzing their views of its usefulness, especially in relation to the employability of graduates. Based on the findings, we offer critical insights into this accreditation process when it takes place in contexts beyond highly industrialized countries.

Performance Evaluation of Multimedia Traffic in Cloud Storage Services over Wi-Fi and LTE Networks

The performance of Dropbox, Google Drive, and OneDrive cloud storage services was evaluated under Wi-Fi and LTE network conditions during multimedia file uploads. Traffic was captured using Wireshark, and key metrics (including delay, jitter, bandwidth, and packet loss) were analyzed. Google Drive maintained the most consistent performance across both types of networks, showing low latency and reduced jitter. Dropbox showed efficient bandwidth utilization, but experienced a longer delay over LTE, attributed to a greater number of intermediate hops. OneDrive presented variable behavior, with elevated packet rates and increased sensitivity to fluctuations in the mobile network. A bimodal distribution of packet sizes was observed and modeled using a dual Poisson function. In general, Wi-Fi connections provided greater stability for multimedia transfers, while LTE performance varied depending on platform-specific implementations. The results contribute to a better understanding of traffic behavior in cloud-based storage applications and suggest further analysis with larger datasets and heterogeneous access networks.

IoT-Driven Smart Management in Broiler Farming: Simulation of Remote Sensing and Control Systems

Parameter monitoring and control systems are crucial in the industry as they enable automation processes that improve productivity and resource optimization. These improvements also help to manage environmental factors and the complex interactions between multiple inputs and outputs required for production management. This paper proposes an automation system for broiler management based on a simulation scenario that involves sensor networks and embedded systems. The aim is to create a transmission network for monitoring and controlling broiler temperature and feeding using the Internet of Things (IoT), complemented by a dashboard and a cloud-based service database to track improvements in broiler management. We look forward this work will serve as a guide for stakeholders and entrepreneurs in the animal production industry, fostering sustainable development through simple and cost-effective automation solutions. The goal is for them to scale and integrate these recommendations into their existing operations, leading to more efficient decision-making at the management level.

Barriers to Integrating Low-Power IoT in Engineering Education: A Survey of the Literature

Low-power Internet of Things (IoT) technologies are becoming increasingly important in engineering education as a tool to help students connect theory to real applications. However, many institutions face barriers that slow down their adoption in courses and labs. This paper reviews recent studies to understand these barriers and organizes them into three groups: technical, organizational, and curricular/pedagogical. Technical barriers include energy management, scalability, and integration issues. Organizational barriers are related to cost, planning, and the need for trained staff. Curricular and pedagogical barriers include gaps in student readiness, limited lab time, and platform choices that depend on budget. By detailing these barriers with practical examples, this paper aims to help educators and academic leaders develop more effective strategies to adopt low-power IoT in engineering programs.
