demanding environments. Major projects include the study, simulation, design and manufacture of: a

scintillator detector used as a mold level sensor in the steelmaking sector, an electromagnetic brake

system used in continuous casting of steel slab s, and finally an induction re-heating system for thin

slabs and billets. Extensive knowledge in all aspects of design engineering from concept to design for

manufacture and design for process. Published results from research in journals while also attending

and presenting the research findings at Engineering and Physics conferences internationally.

RESEARCH THESIS

Measurements of Partial Branching Fractions for charmless semileptonic B

decays with the BaBar experiment and determination of Vub

My PhD thesis was focused on the measurement of the Cabibbo -Kobayashi-

Maskawa matrix element Vub using the inclusive charmless semileptonic decay

B Xulν. This analysis has played a leading role in the current high energy physic s

field as this parameter ( Vub ) is not able to be predicted using theory and can only

be measured by experiment (high precision required) and importantly is a source of

potential new discoveries in physics. My thesis focused on the study of a rare

particle decay (B meson) chain representing around one thousand of the possible

types of decays (about 500Milion of decays analyzed). This data has been

collected with the BaBar detector, an experiment located in SLAC (Stanford-Linear

Accelerator-Centre, Menlo Park, CA, USA). Due to significant signal noise, several

accurate MONTECARLO signal detector response simulations have been

performed in order to model the background appropriately. Following this signal

events have been extracted using a 2 minimization to some sensible kinematic

variables. W ith this analysis Vub has been measured with a total error of around

4% and it represents the most precise international measurement (using inclusive

method). The result of my thesis has been published in Physic Review Letter D,

one of the important physics journal s (Phys.Rev.D86 (2012) 032004 Study of

B Xuln decay in BB events tagged by a fully reconstructed B meson decay and

determination of Vub http://arxiv.org/pdf/1112.0702.pdf). I performed my thesis

analysis using Root which is an object-oriented program and library developed by

CERN scientist and was designed for particle physic data anlysis and contains

several features specific to this field. From October 2007 to January 2008 and fr om

March 2008 to May 2008 I worked at SLAC as Operations Manager (expert on call)

of the BaBar muon detector (IFR). This was a role of significant responsability

where I checked, controlled and repaired the detector during datataking.

UNDERGRADUATE THESIS

Muon Identification in the BaBar experiment

My masters degree thesis focused on the development of an algorithm to identify a

muon particle using the BaBar experiment (International experiment started in

1998 and finished to 2008, placed to SLAC, Stanford linear Accelerator Center,

California, US). This algorithm was implemented using C++. In this case I created

some dedicated methods to separate this (particle) from the others. For example I

created a class (particle candidate) with a method where was possible to

reconstructed some particle information (charg e, momentum, direction, ect) such

as interaction length. As is known the interaction length is very large for the muon

with respect to other particles. I also I actively participated in the replacement of

the RPC detectors (Resistive Plate Chamber) with the LST (Limitated Stream

Tube) detectors in the IFR sub-system (Instrument Flux Returned)

Working experience

2011 - 2013 R&D Physicist / Electromagnetic Devices Researcher

Danieli & C. Officine Meccaniche Spa (Udine, Italy)

Role of researcher in the R&D department of Danieli & C Officine Meccaniche Spa,

a leading global steel company. Responsible for the simulation, design and

development of electromagnetic devices applied in the steel industry. Specialized

in electromagnetic FEA (Finite Element Analysis) simulations (COMSOL

Multiphysics and FLUX 3D), data analysis and process study optimization. At

present I’m involved with two main projects:

Induction heating system for thin slab s and billets: the induction furnace will

perform the re-heating of the steel slabs and billets originated from the casting

section. The purpose is to supply the subsequent rolling stand with slabs and

billets that have a definite and constant temperature within each type of steel .

My key responsibilities include coil design, process optimization and resonant

circuit computation. The system is able to transfer around 74% (2MW) of the

electrical power to the steel piece. The coil has been performed analyzing the

magnetic field path and the eddy currents produced in the slab or billet.

Thermal coil analysis and coil water cooling systems have been studied as

well. The process has been optimized choosing the best solutions in terms of

electrical efficiency and maximum transferred power. Two prototype systems

have been constructed (one for the slab and one for the billet) and tested

achieving excellent results. At present these systems (both slab and billet)

have been sold to two steel companies and will be operative in January 2014.

The data has been analyzed using MATLAB and MathCAD.

Process and apparatus for controlling the flow of liquid metal in a crystallizer for

the continuous casting of thin flat slabs: the process applies to a crystallizer

comprising perimetral walls which define a containment volume for a liquid

metal bath insertable through a discharger placed in the middle of the bath.

The process includes arranging a plurality of electromagnetic brake s, each for

generating a braking zone within said bath, and activating these

electromagnetic brakes either independently parame ters of the fluid-dynamic

conditions of the liquid metal within the bath. My responsibility includes coils

modeling and MHD simulations (Magneto hydrodynamics). The interaction of

an externally imposed magnetic and electric field on the turbulent flow of a

Nicola Gagliardi, via T.Ciconi 18, 33100 Udine, Italy, Mobile:+393*********, email:******@*******.**, Skype:ngagliardi

conducting fluid (melted steel) in a channel is studied using computational

techniques (FEA Analysis). The Navier-Stokes equations and the equations

describing the electromagnetic field Maxwell have been solved

simultaneously. The turbulent fl uid has been describes using k-ε scheme.

Using an electromagnetic brake is possible to control the meniscus steel

velocity and fluctuations (damping) with a good precision and improve the

casting speed and steel quality. After some tests with a prototype, the system

has been sold to a steel company and shortly will become operative (January

2014).

2010 - 2011 Associate Researcher

INFN (Istituto Nazionale Fisica Nucleare), Padova (Italy)

I worked on the Muon detector development of the SuperB experiment. Main

activities included:

R&D: mainly focused on the active components of the detector, i.e. the scintillator

bars, the WLS fibers and the photodetectors to optimize the light collection and

the readout electronics.

Simulation: the iron structure optimization has been studied using a GEANT4

Monte Carlo simulation; the expected muon identification performances have been

evaluated with a neural network algorithm.

Prototype preparation and beam test: R&D achievements will be tested on a full

scale prototype that has been constructed and that will be used to validate the

simulation results. The prototype is composed by a full stack of iron with a

segmentation that allows the study of different detector configurations. A beam

test has been done at Fermilab (Chicago-Usa-December 2010) using a muon/pion

beam with momentum ranging from 1 GeV/c to 5 GeV/c confirming the high

performance of the system.

2009 - 2010 Associate Researcher

University of Padova (Italy)

W orked on the simulation of a scintillator detector system used as a mold level

sensor in the steelmaking sector. This is an innovative detector device able to

measure the powder and steel precision at the same time with excellent precision

(time and position resolution). A prototype as built and tested confirm very good

results starting for the industrialization phase. I performed this study using Monte

Carlo simulation implemented in C++ (defined particular classes for the generation

of random quantities). More in details I studied th e interaction of casual gammas

(random direction) with the matter. In this case I created particular class and

methods to modeling and describe this kind of interaction.
