摘要： Single Board Computers (SBCs) are a key enabler of the Maker movement and have found a place in education. The two dominant SBCs in education, the Arduino and Raspberry Pi, are now commonly used in courses in Engineering, Computer Science, and Robotics [4, 3, 2, 5]. Their ability to inexpensively work with sensors, servos, Wifi, Bluetooth, audio, video, and images opens opportunities for exciting and engaging projects [1]. New, more powerful and/or cheaper platforms continue to be added to the SBC landscape. Examples include the micro:bit, Arduino MKR series, Adafruit Feather, and Teensy.

摘要： Radio frequency identification (RFID) has been widely used in many fields such as object tracking and inventory management. For RFID systems, grouping is a fundamental issue which can support efficient multicast transmissions, dynamic tag management, and accurate aggregate queries. Existing grouping protocols have drawbacks of unknown theoretical communication time, high computational cost on the server end and inability to deal with unexpected tags which are those tags whose IDs have not been collected by readers. In this paper, we would like to address the above limitations and consider a more general grouping problem that allows an arbitrary number of unexpected tags to present. Our objective is to design a protocol that guarantees the reader to efficiently and correctly notify each known tag of its group-ID, while the probability that an unexpected tag is mistakenly notified of any group-ID is smaller than a pre-determined value. In this paper, we first obtain a lower bound on the communication time for solving this generalized grouping problem. Then, we propose a near-optimal protocol, called OPT-G, and prove that its communication time approximately equals the lower bound. Finally, we report extensive simulation results that demonstrate OPT-G's near-optimal performance and its superiority over existing baseline schemes.

摘要： Micro-appearance models offer state-of-the-art quality for cloth renderings. Unfortunately, they usually rely on 3D volumes or fiber meshes that are not only data-intensive but also expensive to render. Traditional surface-based models, on the other hand, are light-weight and fast to render but normally lack the fidelity and details important for design and prototyping applications. We introduce a multi-scale, hybrid model to bridge this gap for thin fabrics. Our model enjoys both the compactness and speedy rendering offered by traditional surface-based models and the rich details provided by the micro-appearance models. Further, we propose a new algorithm to convert state-of-the-art micro-appearance models into our representation while qualitatively preserving the detailed appearance. We demonstrate the effectiveness of our technique by integrating it into a real-time rendering system.

摘要： The advisor-advisee relationship represents direct knowledge heritage, and such relationship may not be readily available from academic libraries and search engines. This work aims to discover advisor-advisee relationships hidden behind scientific collaboration networks. For this purpose, we propose a novel model based on Network Representation Learning (NRL), namely Shifu2, which takes the collaboration network as input and the identified advisor-advisee relationship as output. In contrast to existing NRL models, Shifu2 considers not only the network structure but also the semantic information of nodes and edges. Shifu2 encodes nodes and edges into low-dimensional vectors respectively, both of which are then utilized to identify advisor-advisee relationships. Experimental results illustrate improved stability and effectiveness of the proposed model over state-of-the-art methods. In addition, we generate a large-scale academic genealogy dataset by taking advantage of Shifu2.

关键词： 工程教育专业认证   复杂工程问题   校企协同育人   目标达成  

摘要： 工程教育专业认证的一个重要内容是评价学生是否具有解决复杂工程问题的能力,而绝大多数高校受办学条件限制,在学校单一培养环境下很难达成该项指标。在深刻剖析现有办学模式存在的各类弊端的基础上,提出一种以复杂工程问题为牵引的校企协同育人机制,从校企协同育人机制的理论、校企合作模式探索、协同育人基地建设策略、双师型师资队伍培养、企业导师的遴选与管理、复杂工程问题的甄选与确认办法、学生赴企业实训课程置换规定等方面,详细论述了校企协同育人机制的诸多关键问题,提出了相应的解决方案。通过沈阳航空航天大学计算机学院两年多的实践验证,学生解决复杂工程问题的能力得到了较大幅度提高,就业率和就业质量同步得到了明显提升。

关键词： 男性气概   一战   迷惘的一代   太阳照样升起  

摘要： 战争是证明男性气概的最佳场所,战士也是历史上男性气概的典型示范。战争中体现的“勇敢”“威武”和“荣耀”等精神是评判男性气概的主要内容,形成了男性气概的传统。而海明威,作为书写“男性气概”和“迷惘一代”的杰出作家,显然意识到了新时代对于男性气概提出的新要求。他笔下的男性气概以及对“海明威式英雄”人物的塑造都有对传统男性气概的颠覆和对新时代男性气概实质的思考。因此,与其说海明威笔下“迷惘一代”的男性气概因战争而被阉割,毋宁说是经历了战争之后,对于新时代男性气概的建构。
