Solving the length constrained K-drones rural postman problem

2021

[EN] In this paper we address the Length Constrained K-Drones Rural Postman Problem (LC K-DRPP). This is a continuous optimization problem where a fleet of homogeneous drones have to jointly service (traverse) a set of (curved or straight) lines of a network. Unlike the vehicles in classical arc routing problems, a drone can enter a line through any of its points, service a portion of that line, exit through another of its points, then travel directly to any point on another line, and so on. Moreover, since the range of the drones is restricted, the length of each route is limited by a maximum distance. Some applications for drone arc routing problems include inspection of pipelines, railwa…

An approach to lithic raw material procurement at the middle Palaeolithic site Abrigo de la Quebrada (Chelva, Valencia)

2011

We offer a preliminary characterisation of the lithic raw-materials found in levels I-III of the Middle Paleolithic site of Abrigo de la Quebrada. The artifacts were excavated in the field seasons of 2004 and 2007, have already been the object of a preliminary technological assessment (Villaverde et al. 2008), and their analysis has been preceded by a survey of local procurement sources, carried out in 2008. We present, in a regional context, the different raw-material categories recognized (by means of a macroscopic study), and variants thereof, and we describe the different outcrops identified. Based on these data, we attempt a preliminary assessment of the resource catchments and mobilit…

Is the NZEB Benchmarking Approach Suitable for Assessing Energy Retrofit Design?

2013

Currently, many effort have been done to enable energy saving issues in building design and many definitions have been introduced for most performing constructions based on energy balance between energy demand and supply. Recently, the Net Zero Energy Building theory has bypassed old Passive House concept but many questions still remain open. Present work aims to estimate how NZEB requirements matching could be affected by the choice of their definition and the choice of weighting factor system, to be count in the energy balance. NZEB concept is mainly referred to new buildings design. Its application to existing buildings is for sure an hard task provided the architecture and physical cons…

Digitization and Preservation of Cultural Heritage Products

2017

Cultural heritage encompasses various aspects of a nation's history. Cultural heritage artifacts are considered as priceless items that need special care. Since the wide adoption of new digital technologies, documenting and storing cultural heritage assets became more affordable and reliable. These records are then used in several applications. Researchers saw the opportunity to use digital heritage recordings for long-term preservation. They are considering cultural heritage artifacts as products, and the history behind them as a product lifecycle. In this paper, we present the research progress in cultural heritage digital processing and preservation, highlighting the most impactful advan…

Scenarios of Climatic Resilience, Economic Feasibility and Environmental Sustainability for the Refurbishment of the Early 20th Century Buildings

2019

This paper aims to examine the theme of energy retrofit within the circumscribed field of refurbishment interventions on load-bearing masonry buildings built in the early 20th century. These include a remarkable share of the fabric of many European cities and, in particular, they can be found in geographical areas characterized by a Mediterranean (mild) climate. The main objective is to increase the climate resilience of the buildings by verifying the economic feasibility and the environmental sustainability of the interventions at the same time observing the specific architectural features of the buildings. We put forward alternative retrofit solutions carrying out synoptic comparisons of …

A Framework for a Smart City Design : Digital Transformation in the Helsinki Smart City

2019

Recently, there has been substantial interest in the concept of a smart city, as it has been a viable solution to the dilemmas created by the urbanization of cities. Digital technologies—such as Internet-of-Things, artificial intelligence, big data, and geospatial technologies—are closely associated with the concept of a smart city. By means of modern digital technologies, cities aim to optimize their performance and services. Further, cities actively endorse modern digital technologies to foster digitalization and the emergence of data-based innovations and a knowledge economy. In this paper, a framework for a smart city design is presented. The framework considers a smart city from the pe…

On the impact of safety requirements, energy prices and investment costs in street lighting refurbishment design

2018

Abstract Street lighting is an indispensable feature for the night landscape of cities. It is important for road safety, users visual comfort, crime prevention and to augment the perceived personal safety. Realize and maintain an adequate street lighting service is very expensive for municipalities with significant impact on their budgets. For this reason, special attention should be paid to the design of new street lighting systems and to the refurbishment of existing ones, since many of them are inadequate. In light of this it is very important to implement street lighting designs that fulfil lighting requirements avoiding energy waste and light pollution and, at the same time, result eco…

Human Sociability in Antonio Montecatini's (1537–99) Commentary on Aristotle's Politics

2021

The present article delves into the history of political philosophy by discussing human sociability in Antonio Montecatini's (1537–99) commentary on Aristotle's Politics. The focus is on a philosophical analysis of three interrelated ideas that Montecatini discusses: (1) Aristotle's dictum that human beings are political animals by nature; (2) naturalness of the household; and (3) the nature and origin of political communities. Montecatini's views are briefly related to those of John Case (ca. 1546–1600), and they are also contextualized within the late medieval commentary tradition on the Politics, but the main aim is to clarify Montecatini's philosophical position and examine the ways in …
