The Effect of Damage Functions on Urban Flood Damage Appraisal

2014

Flooding damage appraisal can been obtained by interpolating real damage data caused by historical flooding events or accounting the effects of a flood in terms of the depreciation of assets. Most often, the expected damage is evaluated by means of damage functions describing the relationship occurring between the damage and hydraulic characteristics of flood. The present paper aims to evaluate the uncertainty linked to the choice of the depth-damage function adopted in the flood damage analysis. Several possible depth-damage function formulations were selected in literature and applied to historical flooding events monitored in the "Centro Storico" catchment in Palermo (Italy). (C) 2013 Th…

2011

Author's version of an article published in the journal: IEEE Transactions on Circuits and Systems I: Regular Papers. Also available from the publisher at: http://dx.doi.org/10.1109/tcsi.2011.2106090 The problem of robust mode-dependent delayed state feedback H ∞ control is investigated for a class of uncertain time-delay systems with Markovian switching parameters and mixed discrete, neutral, and distributed delays. Based on the LyapunovKrasovskii functional theory, new required sufficient conditions are established in terms of delay-dependent linear matrix inequalities for the stochastic stability and stabilization of the considered system using some free matrices. The desired control is …

Beyond Tandem Analysis: Joint Dimension Reduction and Clustering in R

2019

We present the R package clustrd which implements a class of methods that combine dimension reduction and clustering of continuous or categorical data. In particular, for continuous data, the package contains implementations of factorial K-means and reduced K-means; both methods combine principal component analysis with K-means clustering. For categorical data, the package provides MCA K-means, i-FCB and cluster correspondence analysis, which combine multiple correspondence analysis with K-means. Two examples on real data sets are provided to illustrate the usage of the main functions.

Interspace for empathy : engaging with work-related uncertainty through artistic intervention in management education

2022

How can artistic intervention facilitate empathic engagement with work-related uncertainty in postgraduate management education? To examine this, we theorize artistic intervention as creating an interspace of temporarily suspended organizational norms through which empathy as relational knowing can emerge between participants. Drawing on an ethnographic study entitled Becoming in Academia, a nine-month artistic intervention conducted by a group of doctoral students in a Nordic business school (NBS), this paper highlights how an interspace for empathic engagement with work-related uncertainty was created by the participants through three intervention activities: aligning oneself to the other…

On the Visual Distraction Effects of Audio-Visual Route Guidance

2016

This is the first controlled quantitative analysis on the visual distraction effects of audio-visual route guidance in simulated, but ecologically realistic driving scenarios with dynamic maneuvers and self-controlled speed (N = 24). The audio-visual route guidance system under testing passed the set verification criteria, which was based on drivers’ preferred occlusion distances on the test routes. There were no significant effects of an upcoming maneuver instruction location (up, down) on the in-car display on any metric or on the experienced workload. The drivers’ median occlusion distances correlated significantly with median incar glance distances. There was no correlation between driv…

Elaboration of a method to categorize substances of interest as regards to their potential endocrine disrupting activity: assessment and categorizati…

2021

EDCs are substances that alter function(s) of the endocrine system and consequently cause adverse health effects. The endocrine system consists of many cells and tissues that interact with each other and the rest of the body by means of hormones. This system is responsible for controlling a large number of processes in the body from gamete formation, to conception and early developmental processes such as organogenesis, and to most tissue and organ functions throughout life. EDCs interfere with endocrine function by many ways and, in doing so, lead to adverse effects on the health of humans and/or wildlife. Some of the observed health effects associated with EDCs include, butare not limited…

Food Security Is None Of Your Business? Food Supply Chain Management In Support Of A Sustainable Food System

2017

Food security is the principal outcome of any given food system and it can be defined in terms of a sustainable food system where the core goal is to feed everyone sustainably, equitably and healthily. A sustainable food system addresses needs for availability, affordability and accessibility, is diverse, ecologically-sound and resilient, and builds the capabilities and skills necessary for future generations. This paper identifies the essential elements of food supply chain management in support of a sustainable food system, which ultimately enhances food security. The existing food supply chain and food system literature is synthesized in order to study the correspondence between public i…

2023

This research instrument was developed for a study on the uncertainty experienced by language raters and the impact of uncertainty on the quality of assessment in the official language examination, the National Certificates of Language Proficiency. The instrument consists of three online questionnaires using Webropol software and a note-taking sheet using Excel spreadsheet software. The survey focused on the assessment of speaking and writing in the intermediate-level Finnish language examination. The questions in the survey include both closed and open questions. Two almost identical versions of all the questionnaires and the Excel sheet were created for the collection of data for the diff…

Uncertainty Analysis in the Evaluation of the DDF Curves Parameters in Climate Change Scenarios

2016

Abstract On the global scale, there is a robust observational evidence that, over the last decades, the frequency and intensity of extreme events significantly changed, even if regional and local studies have highlighted complex and non-uniform spatial patterns. Climate change can cause increased rainfall intensities which leads to an additional impact on drainage systems, due to the alteration of magnitude and frequency of peak flows over their service life. For this reason, the design criteria of urban drainage infrastructures need to be revised and updated, in order to take into account the possible variations of extreme rainfall. In particular, the Depth-Duration-Frequency (DDF) curves,…
