The Up-Cycle Beyond the Crime: The Productive Re-Activation of Confiscated Criminal Assets

La ricerca “The Up-Cycle Beyond the Crime: the Productive Re-Activation of Confiscated Criminal Assets” affronta il tema del reinserimento dei beni confiscati alla organizzazioni criminali in nuovi cicli di vita produttivi. La tesi è sviluppata attraverso tre parti principali. La prima parte è dedicata all’inquadramento scientifico del tema e all’apparato teorico, proponendo un regesto critico delle teorie e dell’evoluzione del concetto di riciclo della città e del territorio, con particolare attenzione alla modalità dell’up-cycle, attingendo sia alla letteratura delle scienze sociali, geografiche ed economiche sia alle pratiche relative alla riattivazione dei metabolismi territoriali. La s…

Improving the Reuse Process is Based on Understanding the Business and the Products: Four Case Studies

2002

The reuse of software engineering assets has been proposed as the most promising alternative for improving productivity and software quality. The improvement of reuse requires understanding of suitable reuse strategies and the software process. In four industrial cases the reuse process is analyzed for the purpose of its improvement and remarkable differences between successful processes are found. Those differences are due to differences in the products and businesses of the analyzed companies. In some cases the product line approach fits the business very well and high level of reuse can be achieved by using it. In other cases the black-box approach to reuse has turned out to suit the bus…

Improving the security of multiple passwords through a greater understanding of the human memory

2016

Multiple passwords are an increasing security issue that will only get worse with time. One of the major factors that compromise multiple passwords is users’ memory, and the behaviors they adopt to compensate for its failures. Through studying memory elements that influence users’ password memorability, we may increase our understanding of the user and therefore make proposals to increase the security of the password authentication mechanism. This dissertation examines the human memory to understand password security behaviors; and moreover, develops new theories and revises prominent memory theories for the password context. This research employs memory theories to not only increase the me…

Manual packing and soil reuse effects on determination of saturated hydraulic conductivity of a loam soil

2022

Abstract Performing laboratory measurement of saturated hydraulic conductivity, Ks, of sieved soil is important for many scientific purposes such as testing theories and methods to determine Ks. A given soil mass can be used only once or it can be reused after a previous use. Little is known on the dependence of the Ks measurements on both the applied packing method and the reuse of the same soil mass. This lack of knowledge makes comparisons among different investigations more or less uncertain. Four packing methods were tested on an initially dry loam soil by measuring Ks with the simplified falling head (SFH) technique. The four methods differed by the used compacting procedure (dropping…

Design Procedures for Soil-Lime Stabilization for Road and Railway Embankments. Part 1-Review of Design Methods

2012

AbstractWhen selecting the appropriate materials for constructing road infrastructures, an important way for minimizing both the economical and environmental impact is to make use of lime for treating soils that are not suitable for road or railways construction.Advances in lime stabilization technique allowed the successful use of this technique also for improving the bearing capacity of the subgrade, with noticeable savings on both aggregate and disposal charges.In this paper a review of internationally adopted design methods for soil-lime mixture is presented, in order to compare testing methods and requirements of the adopted criteria, as discussed in Part 2.

Environmental analysis of different construction techniques and maintenance activities for a typical local road

2017

Abstract In this paper, considering the sever impact of road infrastructures on both the surrounding environment as well as on the consumption of locally available natural resources, different road construction techniques have been studied and compared, in order to be able to rank the best solution in terms of environmental sustainability. For the aims of this study, a Life Cycle Analysis has been carried out on a road infrastructure with the most representative geometrical characteristics among those widely used in Italy, in suburban areas, with the help of an appropriate software, the PaLATE. The environmental effects due to both the use of recycled materials, such as the Reclaimed Asphal…

Sound and reusable components for abstract interpretation

2019

Abstract interpretation is a methodology for defining sound static analysis. Yet, building sound static analyses for modern programming languages is difficult, because these static analyses need to combine sophisticated abstractions for values, environments, stores, etc. However, static analyses often tightly couple these abstractions in the implementation, which not only complicates the implementation, but also makes it hard to decide which parts of the analyses can be proven sound independently from each other. Furthermore, this coupling makes it hard to combine soundness lemmas for parts of the analysis to a soundness proof of the complete analysis. To solve this problem, we propose to c…

Exploratory Analysis of the Relations between Code Cloning and Open Source Software Quality

2010

In recent literature there is still a lack of understanding how the reuse and cloning of software affects its quality. The focus of this study is to analyze the relationships between source code cloning and software quality for the case of open source software project forks (SPFs) as a kind of software reuse. In total 117 releases related to three generations of eight eMule SPFs were scrutinized. Software quality was measured in terms of internal quality attributes. The tools CCFinderX and SoftCalc were used to measure code cloning metrics and internal quality attributes, respectively. In total 8 code cloning metrics and 71 internal quality attributes were analyzed. The quantitative relatio…

The Insect Mushroom Bodies: a Paradigm of Neural Reuse

2013

This paper is devoted to discuss the implementation of models,which are inspired by the fly Drosophila melanogaster and able to handle open problems in the field of robotics such as attention, expectation and sequence learning. The role of the Mushroom Bodies (MBs) in solving these tasks is analyzed in detail and a unifying plausible biologically inspired model is proposed. The developed neural structure is able to show different capabilities in line with the paradigm of neural reuse. The same neural circuit can be exploited to accomplish multiple tasks showing interesting capabilities such as attention, expectation and delayed match-to-sample. The simulation results here reported suggest a…

Using Hierarchies to Adapt Domain Analysis to Software Development

2001

Software development strives toward increasing the amount and quality of the software and at the same time decreasing the costs and development time. One approach to achieve these diverse goals is the systematic software reuse (Biggerstaff and Richter, 1987). In the reuse-oriented software development the key success factor is domain analysis (DA) (Arango, 1989; Lam and McDermid, 1997; Prieto-Diaz, 1994). DA is a process through which information used in software development is identified, captured, and organized with the purpose of making it reusable when creating new systems (Prieto-Diaz, 1990). While the traditional development methods (e.g., Jaaksi et al.,1999; Jacobson et al., 1999) fo…
