摘要： Community technology design is informed by and studied in various and overlapping fields of research and practice, including human-computer interaction (HCI), design studies, computer science, community studies, and community informatics. The paper, titled 'A Classification of cultural engagements in community technology design: Introducing a transcultural approach', proposes a paradigm shift to a transcultural mode of engagement in community technology design. Furthermore, as Halabi et al. ([5]) argue, the process of aligning design intentions in community-based design is one of the most complex and difficult to grasp, as the transition from exploratory, research-intensive phases to formulating design goals is elusive and poorly conceptualised, even more so in multi-stakeholder and participatory projects.

摘要： Linda J. Young, who grew up in the small town of White Deer, Texas, enjoyed math from an early age. Before her senior year in high school, she applied for a National Science Foundation program on probability and FORTRAN programming at the University of Tennessee-Knoxville. After thoroughly enjoying her experience with statistics and computer science, she ended up at West Texas State University (now West Texas A&M University) to pursue her bachelor's and master's degrees in mathematics.

摘要： Structural and vibrational properties of free base, cationic and hydrochloride species derived from both S(-) and R(+) enantiomers of antihistaminic promethazine (PTZ) agent have been theoretically evaluated in gas phase and in aqueous solution by using the hybrid B3LYP/6-31G* calculations. The initial structures of S(-) and R(+) enantiomers of hydrochloride PTZ were those polymorphic forms 1 and 2 experimentally determined by X-ray diffraction. Here, all structures in aqueous solution were optimized at the same level of theory by using the polarized continuum (PCM) and the universal solvation model. As was experimentally reported, variations in the unit cell lead to slight energy, density, and melting point differences between the two forms but, this behavior is not carried through in isotropic condition, like in solution with non-chiral solvents. Hence, the N-C distances, Mulliken, atomic natural population (NPA) and Merz-Kollman (MK) charges, bond orders, stabilization and solvation energies, frontier orbitals, some descriptors and their topological properties were compared with the antihistaminic cyclizine agent. The frontier orbitals studies show that the free base species of both forms in solution are more reactive than cyclizine. Higher electrophilicity indexes are observed in the cationic and hydrochloride species of PTZ than cyclizine while the cationic species of cyclizine have higher nucleophilicity index than both species of PTZ. The presences of bands attributed to cationic species of both enantiomers are clearly supported by the infrared and Raman spectra in the solid phase. The expected 114, 117 and 120 vibration normal modes for the free base, cationic and hydrochloride species of both forms were completely assigned and the force constants reported. Reasonable concordances among the predicted infrared, Raman, UV-Vis and Electronic Circular Dichroism (ECD) with the corresponding experimental ones were found.

摘要： Text classification has always been an important and practical issue so that we need to use the computer to classify and discover the information in the text. If we want to recognize the offending words in a text without human intervention, we should use this. In this article we will compare recurrent neural networks, convolutional neural networks and hierarchical attention networks with detailed information about each of which. We will represent a HAN model using Theano framework, which indicates more accurate validation for large datasets. For text classification problem in large datasets, we will use hierarchical attention networks to get a better result.

摘要： Occupancy detection using ambient sensors has many benefits such as saving energy and money, enhancing security monitoring systems, and maintaining the privacy. However, sensors data suffers from uncertainty and unreliability due to acquisition errors or incomplete knowledge. This paper presents a new heterogeneous sensors data fusion method for binary occupancy detection which detects whether the place is occupied or not. This method is based on using neutrosophic sets and sensors data correlations. By using neutrosophic sets, uncertain data can be handled. Using sensors data fusion, on the other hand, increases the reliability by depending on more than one sensor data. Accordingly, the results of experiments applied using Random Forest (RF), Linear Discriminant Analysis (LDA), and FUzzy GEnetic (FUGE) algorithms prove the new method to enhance detection accuracy.

摘要： Communication between information processing systems becomes a challenge, especially in the "big data" era. It is a mandatory subject in the topic "Architecture and organization" of the computer science curriculum. However, in our experience, it is a rather complex topic for students. Simulation visualization can be used to graphically illustrate various concepts of computer science. In this paper, we present the application of NICSim-vhd, which is an acronym for VHDL-based Network Interface Card simulation model, as a pedagogical tool for supporting undergraduate computer science students' education. NICSim-vhd allows simulating the network-to-memory data path at a network node and generating Value Change Dump (VCD) files for simulation visualization of hardware description languages-based models. We provide a taxonomy of learner engagement with simulation visualization. Grounded in Bloom's well recognized taxonomy of understanding, we suggest how to assess the learning outcomes to which such engagement may lead. (C) 2017 Elsevier B.V. All rights reserved.
