Executive Summary Recent research has demonstrated that the Markowitz efficient frontier is fuzzy and may consist of many statistically indistinguishable frontiers. Therefore, it opens the possibility that an efficient portfolio developed by mean-variance analysis may not be any more efficient than a naively diversified portfolio. Using an efficiency test(More)
In this paper we introduce a code provenance management tool which can track the provenance of source code and generate provenance reports to facilitate best practices for managing intellectual property (IP) throughout the software development lifecycle. We present the IP-aware process supported by the tool and explain how it reduces both the cost and the(More)
Broadband, low loss and cost-effective transmission capability of optical fiber links has led to a widespread applications in almost every field. Instantaneous microwave frequency measurement is one of the fields facilitated by optical communication. In this paper, a new optical technique for microwave frequency measurement, which was based on an optical(More)
This paper presents a full scheme of azimuth follow-up System utilized in a certain model of radar spy. By analyzing the requirements for the performance indexes of the follow up system, with a STK465 thick film integrated circuit as the key unit of the power amplifier, a Heidenhain ROD250 Incremental Optical-electrical Encoder for position sensor and a(More)
Broadband, low loss and cost-effective transmission capability of optical fiber links has led to an burst of applications in every field. Instantaneous microwave frequency measurement is one of the many fields that are facilitated by the technology of optical communication. In this paper, some new optical techniques developed by the authors for microwave(More)
Based on obstacle avoidance of orange fruit harvesting robot, the real-time fruit tree model reconstruction is studied. Modular modeling method is adopted for the reconstruction, which extracts a standard module from the orange fruit tree by configuration study and then gets the fruit tree model after combining the module. Through the comparison between(More)
Based on the Wardrop's equilibrium adopted in traffic assignment, a new model for robust Wardrop's user equilibrium is investigated in this paper and an aggregation function is employed to make the model accordant with reality. The results show that function describe the model is a nonlinear complementarily problem because of max operator. While(More)
Thermal annealing effects on the characteristics of intrinsic defects in unintentionally doped 4H–SiC were investigated. The 4H–SiC samples were prepared by Low-Pressure Chemical Vapor Deposition (LPCVD) technique. Results show that there is only one Electron Spin Resonance (ESR) peak and a broad, from green to yellow, photoluminescence (PL) band were(More)
