Coherence, Teleportation, and Open Systems. Comments on Interpretation of Quantum Mechanics

A physical and philosophical discussion of quantum phenomena of coherence, teleportation and open systems is given. We attempt to show that modern physics can give some impulses for new solutions or new tendencies in philosophy. One of the questions is the problem of what is basic in quantum physics: "substances" or "situations", the problem of an observer or two observers at least, of a whole and a part, or distributive or collective sets, of particle-wave complementarity, and of modalities such as possibility, necessity, probability, potentiality, etc.     

基于d维多粒子纠缠态的(t,n)门限量子秘密共享

为了突破Hilbert空间2维度的局限性，解决秘密重建过程中部分参与者缺席的问题，使用[d]维多粒子纠缠态，提出了一个[(t,n)]门限量子秘密共享方案。秘密分发者制备[n]个[d]维2粒子纠缠对，将第2个粒子分别分发给[n]个参与者。当秘密分发者选择自己手中[t]个粒子进行联合投影测量时，纠缠交换使得参与者手中的对应[t]个粒子坍塌成一个[t]粒子纠缠态。这[t]个参与者通过QFT变换和Pauli运算将份额加入[t]粒子纠缠态。最终，共享的秘密由这[t]个参与者一起合作恢复。安全性分析表明，该方案能抵抗截获-测量-重发攻击、纠缠-测量攻击、合谋攻击和伪造攻击。

Compatibility Condition in Theory of Solid Mechanics (Elasticity,Structures, and Design Optimization)

The strain formulation in elasticity and the compatibility condition in structural mechanics have neither been understood nor have they been utilized. This shortcoming prevented the formulation of a direct method to calculate stress and strain, which are currently obtained indirectly by differentiating the displacement. We have researched and understood the compatibility condition for linear problems in elasticity and in finite element structural analysis. This has lead to the completion of the “method of force” with stress (or stress resultant) as the primary unknown. The method in elasticity is referred to as the completed Beltrami-Michell formulation (CBMF), and it is the integrated force method (IFM) in the finite element analysis. The dual integrated force method (IFMD) with displacement as the primary unknown had been formulated. Both the IFM and IFMD produce identical responses. The IFMD can utilize the equation solver of the traditional stiffness method. The variational derivation of the CBMF produced the existing sets of elasticity equations along with the new boundary compatibility conditions, which were missed since the time of Saint-Venant, who formulated the field equations about 1860. The CBMF, which can be used to solve stress, displacement, and mixed boundary value problems, has eliminated the restriction of the classical method that was applicable only to stress boundary value problem. The IFM in structures produced high-fidelity response even with a modest finite element model. Because structural design is stress driven, the IFM has influenced it considerably. A fully utilized design method for strength and stiffness limitation was developed via the IFM analysis tool. The method has identified the singularity condition in structural optimization and furnished a strategy that alleviated the limitation and reduced substantially the computation time to reach the optimum solution. The CBMF and IFM tensorial approaches are robust formulations because both methods simultaneously emphasize the equilibrium equation and the compatibility condition. The vectorial displacement method emphasized the equilibrium, while the compatibility condition became the basis of the scalar stress-function approach. The tensorial approach can be transformed to obtain the vector and the scalar methods, but the reverse course cannot be followed. The tensorial approach outperformed other methods as expected. This paper introduces the new concepts in elasticity, in finite element analysis, and in design optimization with numerical illustrations.

Telegeoprocessing: The integration of remote sensing,Geographic Information System (GIS), Global Positioning System (GPS) and telecommunication

This paper aims to bring together most of the key issues involved in research in novel systems in telegeoprocessing. Telegeoprocessing can be defined as a new discipline based on real-time spatial databases updated regularly by means of telecommunications systems in order to support problem solving and decision-making at any time and any place . It involves the integration of remote sensing, Geographic Information Systems (GIS), Global Positioning System (GPS) and telecommunications. Telegeoprocessing can be categorized as WebGIS (an integration of Internet and GIS), Mobile Geoprocessing (Wireless Mapping - an integration of mobile computing and GIS) and TeleGIS (an integration of GIS and other telecommunication techniques). This paper presents a comprehensive introduction to the problems encountered in telegeoprocessing engineering and the major technologies and standards related to designing an integrated, fully functional telegeoprocessing system based on the latest multimedia and telecommunication technologies. Overall attention will be given to systems based on remote sensing and GPS and all other technologies for sending data from sensors to GIS systems by means of multimedia telecommunications. Finally, we describe our pilot telegeoprocessing programme, which is currently being carried out in the Laboratory of Remote Sensing Information Sciences, Institute of Remote Sensing Applications, Chinese Academy of Science, China.
