Guest Editorial Special Section on Recent Trends and Developments in Industry 4.0 Motivated Robotic Solutions

2018

The twelve papers in this special section focus on the development of robotic solutions for smart factories in industry - the concept of the fourth industrial revolution (industry 4.0). The inclusion of robotics is expected to deeply change the future manufacturing and production processes, and lead to smart factories that will benefit from the main design principles of Industry 4.0: interoperability, virtualization, decentralization, real-time capability, service orientation, and modularity. Robotics will have a key role in this development since innovative technologies and solutions, traditionally associated with the service robotics sector, are going to migrate to industrial smarter robo…

Breaking layer 2: A new architecture for programmable wireless interfaces

2012

This paper introduces a new architecture for programmable wireless interfaces, aiming at responding to the emerging request of wireless access flexibility and adaptability. Instead of implementing a specific MAC protocol stack, the proposed architecture supports a set of programmable services, devised to customize the wireless access operations according to specific network and application scenarios. The services are composed by means of simpler functions, which in turns work on system primitives (i.e. elementary non-programmable functionalities, natively provided by the system) dealing with the physical transmission and reception of the frames. Our approach significantly differs from softw…

A Simulation Analysis for Assessing the Reliability of AC/DC Hybrid Microgrids - Part I: Underground Station and Car Parking

2021

This paper reports the results of a simulation study with the aim of evaluating the capability of two portions of a hybrid AC/DC MV/LV network of maintaining their operation in off-grid mode during the loss of the main AC grid due to a failure. In particular, the study aims to verify, in the case of islanded operation of the two microgrids, the continuity of the electricity service by exploiting the local generation plants, Energy Storage Systems (ESSs), and other flexible resources managed by suitable algorithms in different energy scenarios. The analysis was carried out considering two microgrids: an underground station and a car parking with Electric Vehicles (EVs). For assessing the per…

Applied study on the rotational molding and processing technology of rotational molds

2021

Computer-aided manufacturing involves a set of computerized activities related to the preparation, launch and follow-up of manufacturing. Computer-aided manufacturing is a tool that allows the use of 3D models based on computer-aided design. This paper addresses the process of rotational formation, with an effective focus on the technology of processing a rotational mold using CAM simulation as a research method. In this sense, the right choice of CNC and cutting tools is essential. The use of numerically controlled machine tools and high-performance cutting tools reduces the number of operations. The manufacturing route realized is specific to the parts machining on numerical control machi…

MASS-PRODUCED ELEMENT IN STRUCTURAL GLASS: “ARTIFICIAL VINEYARD”

2014

The aim is to design an architectural element flexible and easily adaptable to different urban situations using a material such as glass that, for the last years, is being employed as a structural element. The mass-production is rarely applied to glass construction systems that instead are usually designed case by case. The paper reports the results of a research carried out by the Dipartmento di Architettura and Dipartimento DICAM (Dipartimento di Ingegneria Civile, Ambientale, Aerospaziale, dei Materiali), of the University of Palermo, within the project "VESTRA" (POFESR 2007/2013 - Action Line 4.1.1.1), that aims to the experimentation of mass-produced elements in structural glass. The p…

Electrodialysis for water desalination: A critical assessment of recent developments on process fundamentals, models and applications

2018

Abstract The need for unconventional sources of fresh water is pushing a fast development of desalination technologies, which proved to be able to face and solve the problem of water scarcity in many dry areas of the planet. Membrane desalination technologies are nowadays leading the market and, among these, electrodialysis (ED) plays an important role, especially for brackish water desalination, thanks to its robustness, extreme flexibility and broad range of applications. In fact, many ED-related processes have been presented, based on the use of Ion Exchange Membranes (IEMs), which are significantly boosting the development of ED-related technologies. This paper presents the fundamentals…

Flexibility of grid interactive water heaters: The situation in the US

2023

Among different solutions to increase flexibility of electricity system, grid interactive water heaters (GIWHs) can make a large contribution, against a relatively low cost. They can advantageously be used within a single building, a local energy community or within an entire distribution grid, thanks to the very fast response time, low cost, highly distributed resource and widely demonstrated technology. In the near future, the flexibility potential of GIWHs will certainly increase, thanks to the advantageous flexibility programs that have been implementing in some area of the world, with the aim of coordinating several million of GIWHs with the electricity network. In this study, we asses…

FLEXIBILITY OPTIMISATION PLATFORMS FOR ENERGY MANAGEMENT OF SMART POWER SYSTEMS

A preliminary comparative study on the effects of pilates training on physical fitness of young female volleyball players

2019

Introduction: Volleyball is one of the world’s most popular sports and because of its enormous popularity many studies have been conducted in an attempt to understand the better method training required to develop fitness performance by a volleyball player. Among which, Pilates exercises have also offered new effective methods for increasing strength and enhancing flexibility. However, many studies have looked at the benefits of Pilates-based exercises only for low back pain and improvement of a person’s quality of life. Therefore, the purpose of this preliminary causal-comparative study was to examine the effects of Pilates training on some physical fitness components in young female volle…

THE EVALUATION OF MUSCLE FLEXIBILITY IN YOUNG SOCCER PLAYERS

2011

Introduction The agility and coordination are two of many attributes required to become a successful player. Several reports have showed that the training of muscle flexibility leads to improvements both in the coordinative and technical performance, and in the process of motor learning (1). The aim of our study was to evaluate the flexibility of shoulders, trunk and lower limbs in young male soccer players compared to that of sedentary subjects. Methods Twelve players (age: 20.00 ± 3.74 years; weight: 74.25 ± 6.80 kg; height: 178.92 ± 6.65 cm) belonging all to the same soccer team and ten sedentary subjects (age: 21.8 ± 3.12 years; weight: 73.60 ± 5.29 kg; height: 179.50 ± 5.78) were teste…
