Evaluation of the apparent losses caused by water meter under-registration in intermittent water supply

2009

Apparent losses are usually caused by water theft, billing errors, or revenue meter under-registration. While the first two causes are directly related to water utility management and may be reduced by improving company procedures, water meter inaccuracies are considered to be the most significant and hardest to quantify. Water meter errors are amplified in networks subjected to water scarcity, where users adopt private storage tanks to cope with the intermittent water supply. The aim of this paper is to analyse the role of two variables influencing the apparent losses: water meter age and the private storage tank effect on meter performance. The study was carried out in Palermo (Italy). Th…

Planning Rehabilitation Actions on Water Distribution Networks in Condition of Data Scarcity

2011

The paper shows a viable approach to the selection of water networks rehabilitation actions, in condition of data scarcity and uncertainty, based on the use of four concise performance literature indices, allowing the analysis and identification of efficient, reliable and robust rehabilitation alternatives, even if assessed on the basis of a relatively small amount of data. A promising statistical sampling method of water consumptions is also described, that may be fruitfully employed within the proposed approach for drafting water balances at network district scale in order to quantify the extent of leakages. The illustrated case study shows that the selected indices are capable to describ…

Scars Collaborative Telediagnosis Platform Using Adaptive Image Flow

2013

International audience; Telemedicine has been developed to allow practitioners to remotely connect with patients and with other medical staff.We propose a new system (hardware and software), named DICODERM (COllaborative DIagnosis of DERMatosis), which makes it possible to monitor the evolution of scars after the excision of a tumorous dermatosis (like melanoma). The hardware part of this system is composed of a new optical innovative probe with which two types of images can be acquired simultaneously: anatomic with a white light image and functional with a fluorescence image (using autofluorescence from the protoporphyrin within the cancer cell). The software part is composed of two compon…

Remote control within the UJI Robotics Manufacturing Cell using FPGA-based vision

2007

In this paper we present a work in progress of a new remote control system based on networked robots and FPGAs technology. The experimental validation has been carried out within the UJI (i.e. the acronym for University Jaume I) Robotics Manufacturing Cell. The main devices included in this Cell are: a SCARA manipulator (AdeptOne), a robot arm with six degrees of freedom (Motoman), an industrial belt, several sensors and cameras, an FPGA that takes care of the computer vision algorithms (i.e. including grasping determination), and a distributed architecture that allows any user to control remotely via Internet a specific manufacturing task. The different components of this system are connec…

Water losses dynamic modelling in water distribution networks

2015

In the last decades, one of the main concerns of the water system managers have been the minimisation of water losses, that frequently reach values of 30% or even 70% of the volume supplying the water distribution network. The economic and social costs associated with water losses in modern water supply systems are rapidly rising to unacceptably high levels. Furthermore, the problem of the water losses assumes more and more importance mainly when periods of water scarcity occur or when not sufficient water supply takes part in areas with fast growth. In the present analysis, a dynamic model was used for estimating real and apparent losses of a real case study. A specific nodal demand model …

Becoming and Being a Creative and Entrepreneurial Mum in Finland

2020

This chapter explores the pathways of mothers with young children into cultural and creative industries (CCIs). These women can be described as mumpreneurs, meaning that they combine running a business enterprise with looking after their children. Typically unstable, insecure, and unpredictable, CCIs also offer scope for great self-engagement and personal satisfaction. At the same time, the current culture of intensive mothering has made motherhood more challenging than in the past. Mumpreneurship may be a way to ‘have it all’ for the women interviewed for this study. However, critical researchers have suggested that this individual ‘choice’ locks women into marginalised roles in the neolib…

Estimating the environmental and resource costs of leakage in water distribution systems: A shadow price approach.

2016

Water scarcity is one of the main problems faced by many regions in the XXIst century. In this context, the need to reduce leakages from water distribution systems has gained almost universal acceptance. The concept of sustainable economic level of leakage (SELL) has been proposed to internalize the environmental and resource costs within economic level of leakage calculations. However, because these costs are not set by the market, they have not often been calculated. In this paper, the directional-distance function was used to estimate the shadow price of leakages as a proxy of their environmental and resource costs. This is a pioneering approach to the economic valuation of leakage exter…
