نویسندگان: خلاصه: 4 P. Asghari et al. 1 Introduction Eye tracking (ET) is frequently used, for example, in behavioral research and human-computer interaction. Eye movement patterns can reveal detailed infor- mation about the user’s cognitive processes, their attention level, or decision- making processes [3,12]. Applications and research based on ET require reliable and robust data [9]. Traditionally, this requires dedicated hardware with high- resolution cameras and infrared illumination to detect corneal reflections [7]. However, dedicated hardware is expensive and thus limits the pervasive use in real-world applications. This situation may change since, propelled by recent advances in deep learning, appearance-based gaze estimation methods that deliver promising results based on low-cost consumer-grade camera inputs start to emerge [2,10,11,21]. These approaches learn to estimate gazes from a video stream based on large-scale data sets and provide 3D gaze vectors or correspond- ing 2D gaze locations on a screen. Furthermore, they do not require any specific external devices and can be used with standalone computers, laptop built-in webcams, or mobile device consumer-grade cameras. This opens up the possi- bility of developing affordable automated intelligent ET solutions for research, commerce, and the general public. On the way to realize this ambition, webcam ET (wcET) has to address several challenges including gaze estimation accu- racy, gaze estimator prediction time, and that gaze estimation quality can be affected by user movements [11]. This paper aims to contribute to the first step toward utilizing wcET as a low-cost pervasive technology by validating the data quality of a state-of-the-art wcET approach in comparison to the performance of an established, commercially available dedicated eye tracking (dhET) system. Accordingly, we address the following research question in our work: How does the gaze estimates of wcET differ from dhET in practical settings regarding accu- racy, precision, and sampling rate? We will further discuss how the limitations of the data quality may affect the performance of wcET applications

نویسندگان: خلاصه: ID-Based Self-encryption via Hyperledger Fabric Based Smart Contract Ilya Grishkov1, Roland Kromes1(B), Thanassis Giannetsos2, and Kaitai Liang1 1 Cyber Security Group, Delft University of Technology, Delft, The Netherlands I.Grishkov-1@student.tudelft.nl, {R.G.Kromes,Kaitai.Liang}@tudelft.nl 2 Ubitech Ltd., Digital Security and Trusted Computing Group, Athens, Greece agiannetsos@ubitech.eu Abstract. This paper offers a prototype of a Hyperledger Fabric-IPFS based network architecture including a smart contract based encryp- tion scheme that meant to improve the security of user’s data that is being uploaded to the distributed ledger. A new extension to the self- encryption scheme was deployed by integrating data owner’s identity into the encryption process. Such integration allows to permanently pre- serve ownership of the original file and link it to the person/entity who originally uploaded it. Moreover, self-encryption provides strong security guarantees that decryption of a file is computationally not feasible under the condition that the encrypted file and the key are safely stored. Keywords: Blockchain · IPFS · Self-Encryption · Security · Hyperledger Fabric 1 Introduction The modern world is increasingly adopting blockchain technology. The first major market adoption of blockchain happened in 2009 when Bitcoin was introduced [12]. Interest in blockchain solutions grew over the years and lead to the invention of Ethereum - Bitcoin peer but with support for smart contracts which are digital codes enabling the description of complete business logic [1]. The introduction of smart contracts leads to further development in the field of blockchain and cre- ated demand for more industry-friendly solutions that allow to identify users of the system (Know-Your-Customer, Anti-Money-Laundering). Hyperledger Fab- ric was then introduced as a highly modular permissioned blockchain that allows great customization to suit particular industrial needs [3]. Given its customizabil- ity and modularity, Hyperledger Fabric (HLF) is a perfect platform for extending it with various trust and privacy preservation solutions

50 Literacy Strategies Step by Step Fourth Edition - Original PDF
نویسندگان: خلاصه: Young children write “All About . . .” books on familiar topics (Tompkins, 2012). They put together a booklet with four or five pages, write a sentence or two on each page, and add illustrations to elaborate the information presented in the text. Stu- dents read the book to the teacher, who helps them elaborate ideas and correct mechani- cal errors before they share from the author’s chair (see p. 10). As they gain experience writing books with one or two sentences per page, students can expand and elaborate the information they share on each page, gradually increasing the length to a paragraph
The Man Who Understood Democracy - Epub + Converted PDF
نویسندگان: خلاصه: Go back in time. Examine the babe when still in its mother’s arms. See the external world reflected for the first time in the still-dark mirror of his intelligence. Contemplate the first models to make an impression on him. Listen to the words that first awaken his dormant powers of thought. Take note, finally, of the first battles he is obliged to fight. Only then will you understand where the prejudices, habits, and passions that will dominate his life come from. In a manner of speaking, the whole man already lies swaddled in his cradle.1 Alexis de Tocqueville made these observations in Democracy in America to explain his rationale for studying America’s “point of departure.” Of course, the beginning is also where the biographer must start. For the young Tocqueville, that external world was dominated by figures from the highest military and administrative nobility of the Ancien Régime, survivors of the Revolutionary Terror, loyal to the exiled Bourbons, and dead set against the liberal views Tocqueville himself would eventually embrace. Presaging this divergence, Tocqueville displayed considerable independence of mind at an early age, and he repeatedly flouted expectations. At the same time, he developed the habit of casting doubt on much of what he did and sawآیا کتاب مورد نظر هنوز بر روی سایت قرار نگرفته است؟ جای نگرانی نیست! کافی است بر روی گزینه سفارش کتاب کلیک کرده و درخواست خود را ثبت کنید. در کمتر از چند ساعت کتاب شما را آماده خواهیم کرد.
