Run-time scalable NoC for FPGA based virtualized IPs
2017
The integration of virtualized FPGA-based hardware accelerators in a cloud computing is progressing from time to time. As the FPGA has limited resources, the dynamic partial reconfiguration capability of the FPGA is considered to share resources among different virtualized IPs during runtime. On the other hand, the NoC is a promising solution for communication among virtualized FPGA-based IPs. However, not all the virtualized regions of the FPGA will be active all the time. When there is no demand for virtualized IPs, the virtualized regions are loaded with blank bitstreams to save power. However, keeping active the idle components of the NoC connecting with the idle virtualized regions is …
Stabilized Naked Sub-nanometric Cu Clusters within a Polymeric Film Catalyze C-N, C-C, C-O, C-S, and C-P Bond-Forming Reactions
2015
[EN] Sub-nanometric Cu clusters formed by endogenous reduction of Cu salts and Cu nanoparticles are active and selective catalysts for C−N, C−C, C−O, C−S, and C−P bond-forming reactions. Sub-nanometric Cu clusters have also been generated within a polymeric film and stored with full stability for months. In this way, they are ready to be used on demand and maintain high activity (TONs up to 104 ) and selectivity for the above reactions. A potential mechanism for the formation of the sub-nanometric clusters and their electronic nature is presented.
Comparison of novel and conventional calibration techniques for the analysis of urine samples using plasma source mass spectrometry combined with a n…
2012
The accuracy and precision of the analytical data from the analysis of liquid samples with high matrix load often suffer from a compromised performance of the sample introduction system. This is especially significant in the case of miniaturized, pneumatic low flow nebulizers. Alternative low-flow sampling devices based on different operating principles are imperative to overcome this drawback. The superior performance of such an alternative liquid sample introduction system for ICP-MS, the drop-on-demand (DOD) aerosol generator based on thermal inkjet technology, was recently outlined by the same group for the analysis of aqueous standard solutions. Current improvements of the system now a…
Parenting Styles and Adolescents' Self-Esteem in Brazil
2007
Summary.—This study explored the relationship between parenting styles and self-esteem among 1,239 11- to 15-yr.-old Brazilian adolescents (54% girls; M age = 13.4 yr., S!D= 1.4). Teenagers' families were classified into 1 of 4 groups (Authorita tive, Authoritarian, Indulgent, or Neglectful) based on adolescents' answers to the ESPA29 Parental Socialization Scale. Participants completed the AF5 Multidimen sional Self-Esteem Scale which appraises five dimensions: Academic, Social, Emotion al, Family, and Physical. Analyses showed that Brazilian adolescents from Indulgent families scored equal (Academic and Social) or higher (Family) in Self-esteem than adolescents from Authoritative famil…
Secondary prophylaxis vs. on-demand treatment to improve quality of life in severe adult haemophilia A patients: a prospective study in a single cent…
2013
Background Retrospective publications show a decrease in the bleeding frequency and an improvement in the quality of life (QoL) in severe adult haemophilia A (SAHA) after switching from the on-demand treatment (DT) to secondary prophylaxis (SP). But there are no prospective studies which demonstrate, using a haemophilia-specific questionnaire, an improvement in the QoL after such treatment change. The main objective of this study is to prospectively compare the QoL and the musculoskeletal assessment after switching from DT to SP in SAHA using the A36 Hemofilia-QoL®. As secondary objective, we compare the haemarthrosis frequency and factor VIII consumption in DT and SP during a similar perio…
Results of an orthopaedic survey in young patients with severe haemophilia in Spain
2002
Summary. This paper outlines the results obtained in a cross-sectional study of a group of young patients with severe haemophilia A and B. The primary aim of the study was to ascertain the level of orthopaedic complications in the group, the effects that these complications have on quality of life, and the medical resources used on these patients. The secondary aim was to relate their current orthopaedic state to the type of treatment received before the study. The study was carried out in 11 hospitals in Spain, where 70 severe haemophilia patients (factor VIII [FVIII] < 2%), with an average age of 21.6 and a median age of 22, and no inhibitors, were monitored. The percentage of patients s…
Survey on the demand of sicilian physicians for a specific training on human cadavers and animals
2018
Currently, surgical training of physicians in Italy has limited possibilities.Surgical training can be performed on dissection of human bodies as well as in animal laboratories, but experience is very poor. We conducted a survey through an anonymous questionnaire in order to evaluate the opinions of post-graduate physicians on their need for experience training on both human and animal bodies during their medical studies. A total of 165 young Sicilian physicians responded to the survey. Only 14 of them (8.5%) declared they had specific training on a live animal, while 46 (27.9%) reported they already attended cadaver labs. Over 70% assigned the maximum score to the utility of such courses a…
Piracy versus Netflix : Subscription Video on Demand Dissatisfaction as an Antecedent of Piracy
2018
Drawing from cognitive dissonance and neutralization theories, this study seeks to improve the understanding on consumer decision-making between the current legal and illegal video consumption alternatives. We develop and test a research model featuring Subscription Video on Demand (SVOD) satisfaction and various dimensions of SVOD quality as antecedents of video piracy neutralizations and attitudes. Based on results from an online survey among Finnish SVOD users, SVOD satisfaction is primarily determined by content quality, and has a small negative effect on attitude toward piracy through decreased piracy neutralization. However, it appears that current legal services are not seen as true …
Priority Based Coordinated Electric Vehicle Charging System for Heterogeneous Traffic
2020
Despite the environmental and health merits associated with Electric vehicles (EVs), a massive deployment of EVs tends to create new technical and economic challenges for power systems. This is being addressed with different coordinated charging schemes where the charging coordination is distributed across multiple EVs and/or aggregators based on different objectives. This work analyzes an algorithm which maximize the operational profit of a charging station with a high charging station utilization while adhering all the constraints enforced by the utility grid. And it is analyzed the performance of the coordinated charging scheme which facilitates heterogeneous EV users whose arrival is un…
Effect of operation conditions of the drop-on-demand aerosol generator on aerosol characteristics: Pseudo-cinematographic and plasma mass spectrometr…
2014
Abstract The recently presented drop-on-demand (DOD) aerosol generator overcomes some of the drawbacks of pneumatic nebulization, as its aerosol is no longer generated by gas–liquid interaction. In the current study, an advanced imaging technique is presented, based on a CCD camera equipped with magnifying telecentric optics to allow for fast, automated and precise aerosol characterization as well as fundamental studies on the droplet generation processes by means of pseudo-cinematography. The DOD aerosol generator is thoroughly characterized regarding its droplet size distribution, which shows few distinct populations rather than a continuous distribution. Other important figures, such as …
