Ernest Hemingway is hailed by many critics as a great craftsman, and“the most important, outstanding author since the death of Shakespeare”. On the other hand, he is severely criticized by critics who doggedly insist that Hemingway is too limited, his theme is too narrow, and, his characters are mute, insensitive and uncomplicated man. However, a very important aspect in the evaluation of Hemingway seems to have been overlooked both by those who devoutly adore him and those who strongly disparage him. This thesis therefore proposes to take a new perspective in exploring Hemingway‘s writing in the hope of exposing his existentialist ideas - consisting of “the absurd world” , “nada of life”, and “choice and code.” -as expressed in both his maior and his minor work. 相似文献

E-commerce is a very active field of Internet research. A very important aspect of e-commerce is its security. Because of the variety of e-commerce applications, many security policies, protocols and techniques are involved in the deployment of the security. The related standards and protocols of e-commerce are studied in this paper. The general model of e-commerce security is set forth. In this model, two most important e-commerce protocols including secure sockets layer (SSL) and secure electronic transaction (SET) are analyzed. The open problems and new trends of e-commerce security are presented. 相似文献

A methodology is proposed to enable real-time evaluation of the observability of local motions, and generate a local observability cost map to enable informed local motion planning in order to avoid potential degradation or degeneracy in state estimator performance. The proposed approach leverages efficient numerical techniques in nonlinear observability analysis and motion primitive-based planning technique to realize the local observability prediction with real-time performance. The degradation of the state estimation performance can be readily predicted with the local observability evaluation result. The proposed approach is specialized to a representative optimization-based monocular visual-inertial state estimation formulation and evaluated through simulation and experiments. The experimental results demonstrated the ability of the proposed methodology to correctly anticipate the potential state estimation degradation. 相似文献
