A Comparison between Three Meta-Modeling Optimization Approaches to Design a Tube Hydroforming Process

2012

Computer aided procedures to design and optimize forming processes have become crucial research topics as the industrial interest in cost and time reduction has been increasing. A standalone numerical simulation approach could make the design too time consuming while meta-modeling techniques enables faster approximation of the investigated phenomena, reducing the simulation time. Many researchers are, nowadays, facing such research challenge by using various approaches. Response surface method (RSM) is probably the most known one, since its effectiveness was demonstrated in the past years. The effectiveness of RSM depends both on the definition of the Design of Experiments (DoE) and the acc…

PRISMA: towards quality, aspect oriented and dynamic software architectures

2003

The development of software systems must be done using platforms that allow the description of quality, complex, distributed, dynamic and reusable architectural models. We present in this paper PRISMA, an architectural modelling approach based on aspects and components that uses a component definition language (components, connectors and systems) to define architectural types at a high abstraction level and a configuration language to design the architecture of software systems. The component definition language increases reuse allowing importation of COTS and reduces complexity by integrating two modern software development approaches: component-based software development and aspect-orient…

‘I Got To Answer the Way I Wanted To’: Intellectual Disabilities and Participation in Technology Design Activities

2021

User involvement in technology design processes can have positive implications for the designed service, but less is known about how such participation affects people with intellectual disabilities. We explored how 13 individuals with intellectual disabilities experienced participation in the design of a transport support application. The study is based on qualitative interviews, photovoice interviews, participant observations, and Smileyometer ratings. A thematic analysis generated the following themes: a sense of pride and ownership, an experience of socialization, and a sense of empowerment. The findings suggest that participation in design activities is a primarily positive experience t…

Exploring a new incubation model for FinTechs: Regulatory sandboxes

2021

Research on incubation models indicates that incubators and accelerators are crucial catalysts for the development of start-ups. To facilitate start-ups in financial markets, several regulatory authorities have adopted a new incubation model called a ‘regulatory sandbox’. Regulatory sandboxes enable eligible applicants to test their technology-enabled financial solutions for a certain period of time (subject to conditions the regulator imposes). As such, these instruments allow innovation while preventing severe instability in financial markets caused by systemic risk. Despite their importance, management research has devoted little attention to studying how sandboxes operate as a new incub…

Correlation effects in proton transfer reactions in solution

1996

Abstract The effects of correlation energy on proton transfer reactions in solution for [H 2 OHOH 2 ] + and [NH 3 HH 2 O] + systems have been studied. Solvent effects have been represented by means of a continuum model. The proton transfer energy profiles for fixed proton donor-proton acceptor distances have been obtained in the gas phase and in solution, both at the HF/6-311G ∗∗ and MP2/6-311G ∗∗ //HF levels of theory. Differences between the correlation energies calculated in the gas phase and in solution are negligible, showing that solvent effects can be correctly described for these proton transfer processes at the HF level.

The ALHAMBRA survey: Discovery of a faint QSO at z = 5.41

2013

[Aims]: We aim to illustrate the potentiality of the Advanced Large, Homogeneous Area, Medium-Band Redshift Astronomical (ALHAMBRA) survey to investigate the high-redshift universe through the detection of quasi stellar objects (QSOs) at redshifts higher than 5. [Methods]: We searched for QSOs candidates at high redshift by fitting an extensive library of spectral energy distributions-including active and non-active galaxy templates, as well as stars-to the photometric database of the ALHAMBRA survey (composed of 20 optical medium-band plus the 3 broad-band JHKs near-infrared filters). [Results]: Our selection over ≈1 square degree of ALHAMBRA data (∼1/4 of the total area covered by the sur…

Propuesta de indicadores del proceso de enseñanza/aprendizaje en la formación profesional en un contexto de gestión de calidad total

2014

Se propone una batería de indicadores del proceso de enseñanza-aprendizaje diseñados para la práctica cotidiana de la evaluación interna de un centro de formación profesional que permita valorar la eficacia del proceso de E/A y el desarrollo de los factores que influyen en él. Al mismo tiempo, se proponen fórmulas para ajustar algunos indicadores globales que permitan valorar la eficacia del funcionamiento del centro con independencia de los factores externos más relevantes. Los indicadores propuestos pretenden obtener información diferenciada que permita tomar decisiones para mejorar de forma continua el funcionamiento del centro, detectando los factores que actúan como limitantes de los b…

Nonperturbative renormalization constants and light quark masses

2002

We present the results of an extensive non-perturbative calculation of the renormalization constants of bilinear quark operators for the non-perturbatively O(a)-improved Wilson action. The results are obtained at four values of the lattice coupling, by using the RI/MOM and the Ward identities methods. A new non-perturbative renormalization technique, which is based on the study of the lattice correlation functions at short distance in x-space, is also numerically investigated. We then use our non-perturbative determination of the quark mass renormalization constants to compute the values of the strange and the average up/down quark masses. After performing an extrapolation to the continuum …

Technical design report for the upgrade of the ALICE inner tracking system

2014

ALICE (A Large Ion Collider Experiment) is studying the physics of strongly interacting matter, and in particular the properties of the Quark–Gluon Plasma (QGP), using proton–proton, proton–nucleus and nucleus–nucleus collisions at the CERN LHC (Large Hadron Collider). The ALICE Collaboration is preparing a major upgrade of the experimental apparatus, planned for installation in the second long LHC shutdown in the years 2018–2019. A key element of the ALICE upgrade is the construction of a new, ultra-light, high- resolution Inner Tracking System (ITS) based on monolithic CMOS pixel detectors. The primary focus of the ITS upgrade is on improving the performance for detection of heavy-flavour…
