Algunas reflexiones sobre la representación del tiempo en la imaginería maya antigua by Erik Velásquez García

“…This work registers and explores some of the many strategies that Mayan artists of the Classic period (AD 250-900) used to represent or suggest the flow of time: the containment of sculptural volumes, the manipulation of dates, the conventional distribution of figures in the pictorial field, the juxtaposition of different times and spaces, the simultaneous angles of view, the displacement between causes (indicated in the texts) and their effects (represented in the images), the sequence in praesentia, the sequence in absentia, and the peripeteia or eloquent instant that suggests psychologically the feeling of change or turning. …”

Path recommendation based on geographic coordinates and trajectory data by Zhong-an JIANG, Ming WANG, Ya CHEN

“…In order to overcome the lacking of tourism information recommendation at the tourism websites,travel review websites and travel websites,a hybrid density clustering approach was proposed to identify scenic hotspot based on the data of geographical coordinates and tour route data.To help users searching high-quality resources and planning an effective tour path,a tour path generation algorithm was designed which contained all the attractions in the scenic area by using the HITS algorithm to evaluate the attraction and improving the traditional ACO algorithm.The multi algorithm comparison experiment was conducted to evaluate the effectiveness of the hot spots and route planning methods.The results show that the method is efficient and practical.…”

Scheme of Attribute-Based Disclosure Mobile Trust Negotiation by Qiuyun Wang, Wenbao Jiang, Hong Wang

“…For it is difficult to use traditional trust negotiation on the mobile environment,which has large communication overhead,storage overhead and computational overhead,an attribute-based disclosure mobile trust negotiation scheme was proposed.In the negotiation process,two sides in trust negotiation exchange certificate which contains encrypted credential attributes firstly,then,one side in trust negotiation can selectively dispose the sensitive attributes to the other side in trust negotiation procedure based on the trust evaluation result of the other,next,two sides in trust negotiation exchange attribute encryption key based on personal security policy until the trust negotiation was completed.The implementation procedure was given in concrete application instances and the scheme was analyzed.…”
