Vehicle scheduling for rental-with-driver services

2021

Abstract In this paper, we introduce a new vehicle scheduling problem (VSP) with driver consistency faced by rental-with-driver companies. A weekly time-horizon is considered and a set of potential customers, each one associated with a list of required tasks, is assumed. The company can choose to accept or reject a customer, but if accepted, all required tasks must be performed by the same driver. A profit is associated with each customer. The goal is to maximize the company’s total profit, by respecting a list of daily and the weekly drivers’ workload limitations imposed by drivers’ contracts. We propose a mathematical formulation of the problem and design an exact solution method based on…

Diritti fondamentali e principio di proporzionalità

2014

the paper assesses the widespread use of the test of proportionality in fundamental rights adjudication. While constitutional and human rights courts all over the world appear to be consistently engaged in deploying the test of proportionality in order to assess the permissibility of a given rights limitation, this approach is under severe criticism insofar as it is considered an attack to the very idea of fundamental rights. The paper will discuss this criticism of the use of proportionality, and will provide a defense of its use by courts in light of some basic features of the contemporary discourse of fundamental rights.

On the effectiveness of vocal imitations and verbal descriptions of sounds

2014

cote interne IRCAM: Lemaitre14b; None / None; International audience; Describing unidentified sounds with words is a frustrating task and vocally imitating them is often a convenient way to address the issue. This article reports on a study that compared the effectiveness of vocal imitations and verbalizations to communicate different referent sounds. The stimuli included mechanical and synthesized sounds and were selected on the basis of participants' confidence in identifying the cause of the sounds, ranging from easy-to-identify to unidentifiable sounds. The study used a selection of vocal imitations and verbalizations deemed adequate descriptions of the referent sounds. These descriptio…

Il ruolo del white paper sulle offerte al pubblico di cripto-attività alla luce della proposta MiCA

2022

La proposta MiCA, nel regolare il white paper sulle offerte di crypto-assets, sembra tenere in considerazione i benefici e i limiti dei sistemi di voluntary e di mandatory disclosure, non optando integralmente né per il primo, né per il secondo. In quest’ottica, se può condividersi l’approccio regolamentare diretto a graduare, a seconda della tipologia di token offerto, sia il contenuto che l’assoggettamento del documento a mera notifica o ad approvazione ex ante da parte dell’Autorità competente, dubbi sorgono in ordine all’indistinta allocazione dell’onere della prova in capo all’oblato, nei casi di violazione della disciplina del relativo white paper.

Characterization of a digital camera as an absolute tristimulus colorimeter

2003

An algorithm is proposed for the spectral and colorimetric characterization of digital still cameras (DSC) which allows them to be used as tele-colorimeters with CIE-XYZ color output, in cd/m2. The spectral characterization consists in the calculation of the color-matching functions from the previously measured spectral sensitivities. The colorimetric characterization consists in trans- forming the raw RGB digital data into absolute tristimulus values CIE-XYZ (in cd/m2) under variable and unknown spectroradiometric conditions. Thus, in the first stage, a gray balance was applied over the raw RGB digital data to convert them into RGB relative colorimetric values. In the second stage, an algo…

Más allá de Marx: postobrerismo y posmarxismo. Una revisión de los fundamentos teóricos de la multitud y el pueblo

2018

The article is a synthetic essay that exposes the main theoretical lines of the postmarxist approach of Laclau and Mouffe, on the one hand, and the autonomist post-operaism of Negri, Hardt, Virno, etc., on the other hand. These theories are conceived as attempts to rationalize current political bets by various political sectors and social movements. It analyzes both argumentative strategies from «orthodox» Marxism and the structure / superstructure relationship; and the forms of constitution of new subjectivities. It compares the theoretical fundamentals of hegemonic articulations and counter-power experiences. It discusses, likewise, the scope and limitations of the categories of «people» …

Accumulation of disparity in physical activity in old age

2012

Background and aims: The level of physical activity often declines in old age, although many older people would like to be more active than what they are capable of. This leads to unmet physical activity need, the feeling that one’s level of physical activity is inadequate, which is a manifestation of disparity in physical activity in old age. The accumulation of risk factors, including mobility limitations, low socioeconomic status (SES) and lack of social support may increase disparity in physical activity. The aim of this study was to investigate how the accumulation of risk factors is associated with unmet physical activity need in older community-living people. Methods: The study was b…

Sketching Sound with Voice and Gesture

2015

Voice and gestures are natural sketching tools that can be exploited to communicate sonic interactions. In product and interaction design, sounds should be included in the early stages of the design process. Scientists of human motion have shown that auditory stimuli are important in the performance of difficult tasks and can elicit anticipatory postural adjustments in athletes. These findings justify the attention given to sound in interaction design for gaming, especially in action and sports games that afford the development of levels of virtuosity. The sonic manifestations of objects can be designed by acting on their mechanical qualities and by augmenting the objects with synthetic and…

2013

Some European Bronze Age objects were produced by what has been described as serial metalworking. One particularexample is the Middle Bronze Age palstave, massively produced and used in Western Europe during the mid-second millennium BC.These artefacts were often voluntarily buried together in hoards, meaning they were removed from the production network, thus avoidingany recycling. They are found intact, either as rough castings or ready for use. These homogeneous objects are grouped in sets of severalitems, or in tens, or even in hundreds. Such discoveries have immediately led to numerous questions as to the possible interpretation ofthis behaviour. It is clear that prehistoric craftsmen …
