An Improved K-means Algorithm and Its Application for Assessment of Culture Industry Listed Companies
Owing to K-means algorithm has the shortcoming that it always neglects the influence of cluster size when the Euclidean distances between samples and cluster center is calculated. In order to overcome the lack, the influence of cluster size is introduced into K-means algorithm in this paper. Therefore an improved K-means algorithm based on gravity is proposed, namely GK-means algorithm. The experimental simulation results show that GK-means algorithm has better performance compared with K-means algorithm. So the GK-means algorithm is adopted for assessing the performance of culture industry listed companies in this paper. Furthermore some satisfactory results are also obtained

Using computer simulation in operating room management: impacts of information quality on process performance
High quality information has a significant impact on improving operation performance and patient satisfaction, as well as resolving patient disputes. Based on the analysis of the perioperative process, information quality is considered as an important contributory factor in improving patient throughput. In this paper, we propose a conceptual framework to use computer simulations in modeling information flow of hospital process for operating room management (ORM). Additionally, we conduct simulation studies in different levels of the information quality for ORM. The results of our studies provide evidence that information quality can drive process performance in several phases of the ORM
Tendencias investigativas y formativas en Ingeniería Civil en universidades chinas
Trabajo de InvestigaciónLa ingeniería civil es una de las disciplinas más importantes para el desarrollo económico, la cual proporciona los diferentes elementos que permiten dotar de infraestructura a todas las modalidades de transporte, al igual que la mejora en generación y transmisión de energía y desarrollo de obras hidráulicas. Este cubrimiento tan amplio permite incidir en la economía de un país, dado que la actividad constructora demanda gran mano de obra no calificada la cual es primordial para los países que se encuentran en desarrollo, de igual forma la mano de obra especializada que permita el desarrollo de importantes proyectos como lo son túneles, puentes, embalses y vías. Debido a la gran importancia de estas infraestructuras para el desarrollo de un país, esta rama de la ingeniería es reconocida por todos los países, es por ello que la presente investigación busca establecer las tendencias formativas e investigativas que se presentan en China en cuanto a ingeniería Civil. Y por ello se lleva a cabo una caracterización y evaluación actual de los planes de estudios de programas de ingeniería de universidades que ofrecen esta disciplina en China, a través de filtros investigativos y la recuperación de información y análisis desde las páginas Web de cada institución. Posteriormente, se analizan los criterios de comparación de los planes de estudios, que permiten detectar las principales diferencias entre las universidades. Por otra parte, se realizó un análisis de las tendencias investigativas de las universidades Chinas, con el fin identificar el comportamiento investigativo en las mismas universidades. Se espera que la investigación logre como resultado, conocer la tendencia investigativa de Ingeniería Civil, en las mejores universidades de China.PregradoIngeniero Civi
Millet agriculture dispersed from Northeast China to the Russian Far East: integrating archaeology, genetics, and linguistics
Broomcorn and foxtail millets were being cultivated in the West Liao River basin in Northeast China by at least the sixth millennium BCE. However, when and how millet agriculture spread from there to the north and east remains poorly understood. Here, we trace the dispersal of millet agriculture from Northeast China to the Russian Far East and weigh demic against cultural diffusion as mechanisms for that dispersal. We compare two routes for the spread of millet into the Russian Far East discussed in previous research—an inland route across Manchuria, and a coastal/inland route initially following the Liaodong Peninsula and Yalu River—using an archaeological dataset including millet remains, pottery, stone tools, spindle whorls, jade and figurines. We then integrate the archaeological evidence with linguistic and genetic findings in an approach we term ‘triangulation’. We conclude that an expansion of agricultural societies in Northeast China during the Middle to Late Hongshan (4000–3000 BCE) coincided with the arrival of millet cultivation in eastern Heilongjiang and the Primorye province of the Russian Far East. Our findings support the inland, Manchuria route for the dispersal of millet to the Primorye and suggest that, as well as long-distance cultural exchange, demic diffusion was also involved. Our results are broadly compatible with the farming/language dispersal hypothesis and consistent with a link between the spread of millet farming and proto-Tungusic, the language ancestral to the contemporary Tungusic languages, in late Neolithic Northeast Asia. © 2020 The Author
Local-Global Temporal Difference Learning for Satellite Video Super-Resolution
Optical-flow-based and kernel-based approaches have been widely explored for
temporal compensation in satellite video super-resolution (VSR). However, these
techniques involve high computational consumption and are prone to fail under
complex motions. In this paper, we proposed to exploit the well-defined
temporal difference for efficient and robust temporal compensation. To fully
utilize the temporal information within frames, we separately modeled the
short-term and long-term temporal discrepancy since they provide distinctive
complementary properties. Specifically, a short-term temporal difference module
is designed to extract local motion representations from residual maps between
adjacent frames, which provides more clues for accurate texture representation.
Meanwhile, the global dependency in the entire frame sequence is explored via
long-term difference learning. The differences between forward and backward
segments are incorporated and activated to modulate the temporal feature,
resulting in holistic global compensation. Besides, we further proposed a
difference compensation unit to enrich the interaction between the spatial
distribution of the target frame and compensated results, which helps maintain
spatial consistency while refining the features to avoid misalignment.
Extensive objective and subjective evaluation of five mainstream satellite
videos demonstrates that the proposed method performs favorably for satellite
VSR. Code will be available at \url{https://github.com/XY-boy/TDMVSR}Comment: Submitted to IEEE TCSV
