BlockNet: a distributed simulation and control framework with precedence constrain management based on dotnet
No full textBlockNet: A new flexible control architecture
No full textA novel multiplatform control framework named
BlockNet is introduced. It can be used either for simulations,
soft real-time control in real experiments and integration of
complex technologies (e.g neural networks, vision sensors etc.).
BlockNet has been developed to provide an easy to use unique
tool for local or distributed applications able to guarantee
the correct execution order of block codes based on their
dependencies, maintaining dynamism and portability. To the
best of our knowledge such features are not currently provided
at once in other frameworks. We discuss the features of
BlockNet, its main structures and functionalities, providing also
its effectiveness in a real control application: an earthquake
simulation platform
Optimization methodology for an automotive cross-member in composite material
No full textOptimization methods are useful and effective techniques for the design and development of components from the weight reduction point of view. This paper presents an optimization methodology applied to the front cross-member of a Maserati chassis for metal replacement application with the objective of the minimization of the mass of the structure using composite materials. Firstly, a topological optimization of the front side of the vehicle is performed, and the available design space is considered to determine the optimal load path of the design volume and, consequently, to assess a preliminary geometry of the component under scrutiny. Secondly, free-size optimization of the preliminary cross-member design is developed, initially neglecting and subsequently considering the manufacturing constraints. In addition, a linear analysis of the cross-member, modeled as a rigid component, is carried out to evaluate the maximum contribution of this component on the structural performance of the front side of the vehicle. Finally, size and shuffle optimizations are carried out on the new design concept to determine the number and the thickness of the composite plies, and the optimal stacking sequence, respectively, in order to fulfill the structural requirements. A comparison between the new composite structure and the aluminium Maserati cross-member is presented
Privacy Limitations Of Interest-based Advertising On The Web: A Post-mortem Empirical Analysis Of Google's FLoC
No full textIn 2020, Google announced it would disable third-party cookies in the Chrome
browser to improve user privacy. In order to continue to enable interest-based
advertising while mitigating risks of individualized user tracking, Google
proposed FLoC. The FLoC algorithm assigns users to "cohorts" that represent
groups of users with similar browsing behaviors so that ads can be served to
users based on their cohort. In 2022, after testing FLoC in a real world trial,
Google canceled the proposal with little explanation. In this work, we provide
a post-mortem analysis of two critical privacy risks for FloC by applying an
implementation of FLoC to a browsing dataset collected from over 90,000 U.S.
devices over a one year period. First, we show how, contrary to its privacy
goals, FLoC would have enabled cross-site user tracking by providing a unique
identifier for users available across sites, similar to the third-party cookies
FLoC was meant to be an improvement over. We show how FLoC cohort ID sequences
observed over time can provide this identifier to trackers, even with
third-party cookies disabled. We estimate the number of users in our dataset
that could be uniquely identified by FLoC IDs is more than 50% after 3 weeks
and more than 95% after 4 weeks. We also show how these risks increase when
cohort data are combined with browser fingerprinting, and how our results
underestimate the true risks FLoC would have posed in a real-world deployment.
Second, we examine the risk of FLoC leaking sensitive demographic information.
Although we find statistically significant differences in browsing behaviors
between demographic groups, we do not find that FLoC significantly risks
exposing race or income information about users in our dataset. Our
contributions provide insights and example analyses for future approaches that
seek to protect user privacy while monetizing the web.Comment: Author version of paper In Proceedings of the 2022 ACM SIGSAC

No full textDevelopment of Case Material for Confederates in Arizona State University Nursing Simulations
No full textabstract: This paper reviews a creative project designed to enhance the simulation experience for College of Nursing and Health Innovation nursing students at Arizona State University. Simulation allows students to practice imperative skills in a safe environment, free from the risk of injury to patients and the consequences of making these errors, in order to master skills that are essential in the clinical setting. Students are able to practice a wide range of invasive and noninvasive skills and hone in on their clinical judgement and critical thinking to make decisions that may be life threatening in a clinical situation. The group members designed written training materials and created corresponding video vignettes that would be utilized to enhance the confederate role and provide the students a deeper understanding of their simulated patient and the simulation scenario. The written training materials that were developed include confederate background information, patient and family education, and guided questions and answers for the video vignettes. The written training materials will be used to guide the students that are portraying the family member during the simulation. Trained standardized patients were hired to play the confederate role in the four video vignettes. The video vignettes portrayed interviews with a family member of the patient that delved into how they felt about their family member's hospitalization and what they hoped to learn from the nurses during their family member's hospitalization. The vignettes will be used to guide students to the needs of the patients and families in the corresponding scenarios. These vignettes will be accessible by students before the start of simulation in order to enhance understanding of the patient and ultimately, the scenario
Numerical-experimental correlation of thin wall hollow section aluminum castings for car body applications
No full textRecent progress in L-H transition studies at JET: Tritium, Helium, Hydrogen and Deuterium
No full textWe present an overview of results from a series of L-II transition experiments undertaken at JET since the installation of the ITER-like-wall (JET-ILW), with beryllium wall tiles and a tungsten divertor. Tritium, helium and deuterium plasmas have been investigated. Initial results in tritium show ohmic L-H transitions at low density and the power threshold for the L-H transition (P-LH) is lower in tritium plasmas than in deuterium ones at low densities, while we still lack contrasted data to provide a scaling at high densities. In helium plasmas there is a notable shift of the density at which the power threshold is minimum ((n) over bar (e,min)) to higher values relative to deuterium and hydrogen references. Above (n) over bar (e,min) (He) the L-H power threshold at high densities is similar for D and He plasmas. Transport modelling in slab geometry shows that in helium neoclassical transport competes with interchange-driven transport, unlike in hydrogen isotopes. Measurements of the radial electric field in deuterium plasmas show that E-r shear is not a good indicator of proximity to the L-H transition. Transport analysis of ion heat flux in deuterium plasmas show a non-linearity as density is decreased below (n) over bar (e,min). Lastly, a regression of the JET-ILW deuterium data is compared to the 2008 ITPA scaling law
Structural rearrangements as a recurrent pathogenic mechanism for SETBP1 haploinsufficiency
No full textChromosomal structural rearrangements consist of anomalies in genomic architecture that may or may not be associated with genetic material gain and loss. Evaluating the precise breakpoint is crucial from a diagnostic point of view, highlighting possible gene disruption and addressing to appropriate genotype–phenotype association. Structural rearrangements can either occur randomly within the genome or present with a recurrence, mainly due to peculiar genomic features of the surrounding regions. We report about three non-related individuals, harboring chromosomal structural rearrangements interrupting SETBP1, leading to gene haploinsufficiency. Two out of them resulted negative to Chromosomal Microarray Analysis (CMA), being the rearrangement balanced at a microarray resolution. The third one, presenting with a complex three-chromosome rearrangement, had been previously diagnosed with SETBP1 haploinsufficiency due to a partial gene deletion at one of the chromosomal breakpoints. We thoroughly characterized the rearrangements by means of Optical Genome Mapping (OGM) and Whole Genome Sequencing (WGS), providing details about the involved sequences and the underlying mechanisms. We propose structural variants as a recurrent event in SETBP1 haploinsufficiency, which may be overlooked by laboratory routine genomic analyses (CMA and Whole Exome Sequencing) or only partially determined when associated with genomic losses at breakpoints. We finally introduce a possible role of SETBP1 in a Noonan-like phenotype
