Современное состояние электрификации России

В статье показано, что современное развитие электрификации РФ в сопоставлении с государствами, входящими в G8, очевидно недостающее. При этом есть большой потенциал электросбережения в секторах экономики. Потребление электроэнергии населением существенно находится в зависимости от значения их денежных доходов и темпов роста тарифов на электричество

Analyzing the Sensitivity to Faults of Synchronization Primitives

Modern multi-core processors provide primitives to allow parallel programs to atomically perform selected operations. Unfortunately, the increasing number of gates in such processors leads to a higher probability of faults happening during the computation. In this paper, we perform a comparison between the robustness of such primitives with respect to faults, operating at a functional level. We focus on locks, the most widespread mechanism, and on transactional memories, one of the most promising alternatives. The results come from an extensive experimental campaign based upon simulation of the considered systems. We show that locks prove to be a more robust synchronization primitive, because their vulnerable section is smaller. On the other hand, transactional memory is more likely to yield an observable wrong behaviour in the case of a fault, and this could be used to detect and correct the error. We also show that implementing locks on top of transactional memory increases its robustness, but without getting on par with that offered by locks

Parallel paradigms and run-time management techniques for many-core architectures

The 2PARMA project aims at providing parallel programming models and run-time resource management techniques to exploit the features of many-core processor architectures, by focusing on the definition of parallel programming models that combine component-based and single-instruction multiplethread approaches, instruction set virtualisation based on portable bytecode, run-time resource management policies and mechanisms as well as design space exploration methodologies for Many-core Computing Fabrics

Parallel paradigms and run-time management techniques for many-core architectures: 2parma approach

The 2PARMA project aims at overcoming the lack of parallel programming models and run-time resource management techniques to exploit the features of many-core processor architectures. More in detail, the 2PARMA project focuses on the definition of a parallel programming model combining component-based and single-instruction multiple-thread approaches, instruction set virtualisation based on portable bytecode, run-time resource management policies and mechanisms as well as design space exploration methodologies for Many-core Computing Fabrics

Insight from an Italian Delphi Consensus on EVAR feasibility outside the instruction for use: the SAFE EVAR Study

Background: The SAfety and FEasibility of standard EVAR outside the instruction for use (SAFE-EVAR) Study was designed to define the attitude of Italian vascular surgeons towards the use of standard endovascular repair (EVAR) for infrarenal abdominal aortic aneurysm (AAA) outside the instruction for use (IFU) through a Delphi consensus endorsed by the Italian Society of Vascular and Endovascular Surgery (Società Italiana di Chirurgia Vascolare ed Endovascolare - SICVE). Methods: A questionnaire consisting of 26 statements was developed, validated by an 18-member Advisory Board, and then sent to 600 Italian vascular surgeons. The Delphi process was structured in three subsequent rounds which took place between April and June 2023. In the first two rounds, respondents could indicate one of the following five degrees of agreement: 1) strongly agree; 2) partially agree; 3) neither agree nor disagree; 4) partially disagree; 5) strongly disagree; while in the third round only three different choices were proposed: 1) agree; 2) neither agree nor disagree; 3) disagree. We considered the consensus reached when ≥70% of respondents agreed on one of the options. After the conclusion of each round, a report describing the percentage distribution of the answers was sent to all the participants. Results: Two-hundred-forty-four (40.6%) Italian Vascular Surgeons agreed to participate the first round of the Delphi Consensus; the second and the third rounds of the Delphi collected 230 responders (94.3% of the first-round responders). Four statements (15.4%) reached a consensus in the first rounds. Among the 22 remaining statements, one more consensus (3.8%) was achieved in the second round. Finally, seven more statements (26.9%) reached a consensus in the simplified last round. Globally, a consensus was reached for almost half of the proposed statements (46.1%). Conclusions: The relatively low consensus rate obtained in this Delphi seems to confirm the discrepancy between Guideline recommendations and daily clinical practice. The data collected could represent the source for a possible guidelines' revision and the proposal of specific Good Practice Points in all those aspects with only little evidence available
