COMBINED USE OF INNOVATIVE PASSIVE CONTROL DEVICES AND CONVENTIONAL BASE ISOLATION STRATEGIES

2021

This manuscript contains the main part of my research performed in the last three years at the Department of Engineering, University of Palermo, at the Department of Basic Sciences in Engineering Sciences (Unit of Applied Mechanics), University of Innsbruck, Austria and at the company FIP Mec, Selvazzano Dentro, Padova. Within the research framework of Structural Control, this dissertation proposes novel passive control strategies to mitigate the dynamic response of base isolated structural systems. Among the several types of devices proposed in literature, Tuned Mass Dampers and Tuned Liquid Column Dampers are undoubtedly the most widely employed vibration control devices for coupling with…

Robust Fault Detection of Linear Uncertain Time-Delay Systems Using Unknown Input Observers

2013

This paper deals with the problem of fault detection for linear uncertain time-delay systems. The proposed method for Luenberger observers is developed for unknown input observers (UIOs), and a novel procedure for the design of residual based on UIOs is presented. The design procedure is carried out based on the ${H}_{\infty }$ model matching approach which minimizes the difference between generated residuals by the optimal observer and those by the designed observer in the presence of uncertainties. The optimal observer is designed for the ideal system and works so that the fault effect is maximized while the exogenous disturbances and noise effects are minimized. This observer can give di…

Isolation frequency and efficiency of mycoparasitic Pythium species in the West Mediterranean region of Turkey

2021

Abstract A total of 132 mycoparasitic Pythium isolates were obtained from the soil samples taken from fruit orchards, vegetable fields, carnation greenhouses, sugarbeet fields and cereal fields in the West Mediterranean region of Turkey. The Oomycetes were isolated by using; surface soil dilution plate, sclerotia bait and precolonised plate methods. Isolates were identified as P. acanthophoron, P. amasculinum, P. lycopersicum, P. oligandrum, P. periplocum and P. paroecandrum, according to their morphological and molecular characteristics. The most commonly isolated mycoparasitic species were P. amasculinum and P. lycopersicum. The majority of the mycoparasites came from soil samples taken f…

An overview of the role of T cells in controlling tuberculosis infection in a pediatric population

2015

The most significant immunological studies of tuberculosis (TB) infection have involved adult patients. Few studies about the immune repertoire have been conducted in children. The purpose of this paper is to focus on cellular immune response to Mycobacterium tuberculosis by reviewing our studies conducted on children with different forms of TB infection between 1998 and 2006. Although the gold standard of TB diagnosis remains isolation of TB bacillus that also allows estimation of pattern of resistance of M. tuberculosis, the study of immune response can be useful for the early diagnosis and therapeutic follow-up of pediatric TB.

INFEZIONE POLMONARE DA BLASTOSCHIZOMICES CAPITATUS

2005

Geotrichum capitatum, now known as Blastoschizomyces capitatus, can be responsible for several opportunistic infections (systemic infection or localized at lungs, liver, kidney, encephalitis or meningitis) in an immunocompromised host, especially in those patients affected by leukaemia or under immunosuppressive therapies. A 66-year-old woman with polimyosite under steroid and immunosuppressant therapy was hospitalized in ICU for an acute respiratory distress with moderate hypoxaemia and normocapnia. Pulmonary X-ray revealed a bilateral pneumonia. Hypoxaemia became severe 48 hours later and the patient underwent mechanical ventilation and empirical antibiotic therapy. Blood cultures, urine …

Multiple Candidacies and the Role of the Lowest Electoral Tier for Individualized Campaigning

2015

The effects of mixed electoral systems on politicians’ incentives and work in the legislature are most often studied in isolation from the possibly mediating role of campaign behavior. The tier in which a candidate runs might determine a particular style and content of campaigning, more or less party centered and more or less constituency oriented, which in turn could shape how the elected politician will perceive her mandate and act upon it. But what type of campaigning prevails when candidacy in multiple tiers is the rule and the majoritarian element is the dominant component of the mixed electoral system? The present study draws on a survey of 431 candidates in the 2010 Hungarian parlia…

GekkoFS — A Temporary Burst Buffer File System for HPC Applications

2020

Many scientific fields increasingly use high-performance computing (HPC) to process and analyze massive amounts of experimental data while storage systems in today’s HPC environments have to cope with new access patterns. These patterns include many metadata operations, small I/O requests, or randomized file I/O, while general-purpose parallel file systems have been optimized for sequential shared access to large files. Burst buffer file systems create a separate file system that applications can use to store temporary data. They aggregate node-local storage available within the compute nodes or use dedicated SSD clusters and offer a peak bandwidth higher than that of the backend parallel f…

Predicting Social Distancing Intention and Behavior During the COVID-19 Pandemic: An Integrated Social Cognition Model.

2020

Abstract Background Social distancing is a key behavior to minimize COVID-19 infections. Identification of potentially modifiable determinants of social distancing behavior may provide essential evidence to inform social distancing behavioral interventions. Purpose The current study applied an integrated social cognition model to identify the determinants of social distancing behavior, and the processes involved, in the context of the COVID-19 pandemic. Methods In a prospective correlational survey study, samples of Australian (N = 365) and U.S. (N = 440) residents completed online self-report measures of social cognition constructs (attitude, subjective norm, moral norm, anticipated regret…
