The introduction of the ICTs (Information and Communication Technologies) in education has set a new paradigm in knowledge acquisition. The Internet, overhead projectors and interactive boards, presentation and animation software, and online databases are only some resources that teachers use in order to present information in a more dynamic, immediate, and stunning way, transforming and revitalizing the teaching-learning process. The ICTs have been established in the university classroom and nowadays, they have become an essential part in this teaching-learning process. Lecturers make use of them in the same proportion as they make of traditional materials. At the same time, students have to be acquainted with these new technologies and they also have to be able to deal with them. The objective of this paper is twofold: On the one hand, we study and show how our students make use of the technologies when they have to face their oral presentations in the subject Advanced English: Professional Settings (English Studies Degree at Universitat Jaume I in Castellen, Spain). It is acknowledged that visual aids can be helpful to support a speech, but we want to analyze if the visual aids are successfully applied, how and to which extent. On the other hand, we want to make out the opinions of their classmates about the use of these graphical resources (students fill in a questionnaire about the effectiveness of the visual aids in their classmates' presentations and how they would improve them). Results demonstrate that not only teachers make advantage of the new technological resources, we show, based on the students' oral presentations and their peer-reviews, that also our university students are increasingly aware of the advantage and importance of the ICTs in the classroom. 展开更多

侧信道碰撞分析通过度量泄漏信号之间的关联相似性,巧妙绕过了繁琐的泄漏建模步骤,通过联立碰撞方程组,极大减小了主密钥搜索空间.然而,当前研究局限于S盒输出,并且方程建立以子密钥为单位,这种粗粒度数学关系无法提供足够的鲁棒性保证... 侧信道碰撞分析通过度量泄漏信号之间的关联相似性,巧妙绕过了繁琐的泄漏建模步骤,通过联立碰撞方程组,极大减小了主密钥搜索空间.然而,当前研究局限于S盒输出,并且方程建立以子密钥为单位,这种粗粒度数学关系无法提供足够的鲁棒性保证.本文首次提出了以S盒输入作为选择函数的比特级侧信道碰撞分析方案,并以常见的汉明泄漏为例给出了刻画其子分布代数特征的理论公式框架.在真实攻击中,该方案猜测不同子密钥在相同比特位置的碰撞关系,基于子分布间可相互区分的T检验和F检验结果,通过交叉泄漏样本,构造混合分布,最终利用分布度量散度工具评估差异以验证猜测.实验表明,即使在AES和PRESENT的非严格汉明重量的真实泄漏上,攻击也能达到期望效果.对于AES实现来说,10000条侧信道泄漏样本能使得攻击达到90%的成功率和1.1的猜测熵,而对于PRESENT实现来说达到相同的攻击效果仅需400条. 展开更多

Thetechnical,economic,and environmental performance of solar hot-water(SWH)systems for Swedish residential apartments—where approximately 80%of household energy is devoted to space heating and sanitary hotwater production—was assessed.Two collector types,flat plate(FP)and evacuated tube(ET),were simulated in TSOL Pro 5.5 for five major cities(Stockholm,Goteborg,Malmo,Uppsala,Linkoping).Climatic data and cold-water temperatures were sourced fromMeteonorm7.1,and economic parameters were derived fromrecent national statistics and literature.All calculations explicitly accounted for heat losses from collectors,storage tanks,and internal and external piping systems,and established solar-fraction equations and NPV methodology were applied.Sensitivity analyseswere conducted to determine optimal collector area and hot-water storage volume.Additionally,a Monte Carlo uncertainty analysis(10,000 iterations,±10%)and break-even subsidy/carbon-credit assessments were performed.The discount rate for NPV calculations was set at 0% for capital interest with a 5%reinvestment return over a 25-year lifespan.The highest annual solar heat yield(8017.5 kWh)was obtained in Malmo with 32 m^(2) of ET collectors,meeting 52.7%of total heating demand.Annual CO_(2) emissions were avoided by FP and ET systems by approximately~9.07 and~10.55 tonnes,respectively.Economic analysis showed that no payback was achieved without government allowance;however,at a$0.05/m^(2) allowance,positive NPV was exhibited at all stations.Lower levelized heat costs were delivered by FP systems,while ET systems demonstrated consistent superiority under climatic and economic variability according to the Monte Carlo analysis.Optimal design parameters were identified as 32 collectors and a 1680 L heating buffer tank,and Sankey diagrams highlighted collector losses as the dominant inefficiency.It was concluded that properly designed SWH systems,when supported by targeted subsidies,can significantly reduce fossil-fuel demand and CO_(2) emissions in Swedish residential buildings.This work provides the first city-specific technical–economic–environmental dataset for Sweden,establishes a foundation for a national solar-heating atlas,and informs policymaking toward 100%renewable energy targets;beyond the baseline evaluation,explicit subsidy and carbon-price thresholds,quantified uncertainty ranges,and loss-flow visualizations are also provided,reinforcing the robustness and policy relevance of the findings. 展开更多
