Matching precision is very important and difficult in accurate photography, remote sensing and 3D reconstruction. After analyzing the advantages and shortcomings of current matching algorithms and the epipolar geometry, a new matching algorithm based on global viewpoint difference rectification for framework imagery is devised. Without the aid of orientation parameters, this algorithm contains three parts, the scale rectification for an overall comfortable of the image, the viewport rectification for compensating the bias between the vertical plane of the primary optical axis and the main plane of the scene, and the consistent transformation of two images with different viewports. Following, the details of the implementation of our methods are also given. The validation experiments of the matching precision show that, the new algorithm can improve the precision dramatically, which is better than many other good matching algorithms. © 2015 IEEE.

The radio frequency simulation system (RFSS) is important for the research and development of the airborne radio frequency electronics system, and it is difficult to improve the angle accuracy of the RFSS with conventional three-radiating-unit array. The method of improving the angle accuracy of the RFSS by using the multiple-radiating-unit array instead of the conventional three-radiating-unit array. Comparing with the conventional three-radiating-unit array, the amplitudes of the units in the multiple-radiating-unit array cannot be determined only by the locations of the target and the units. Therefore, the optimization model is built to minimize the angle error. With the result of the optimized amplitudes, the expression of the angle error is given for the multiple-radiating-unit array. Based on the numerical computation results, it can be seen that the angle error of the multiple-radiating-unit array is decreased obviously compared with that of the conventional three-radiating-unit array. It is significant for the improvement of the angle accuracy of the RFSS further. © 2016, Editorial Office of Systems Engineering and Electronics. All right reserved.

Magnetic nanovortices, so-called "skyrmions", count among the most promising candidates for the future of information technology. Processors and storage media making use of these tiny structures could one day lead to the further miniaturization of IT devices and improve their energy efficiency significantly. Materials possessing suitable vortices can be identified in particular by their topological charge, an essential characteristic of skyrmions. To determine this property experimentally has up to now been a very laborious process. Physicists from Jülich have now put forward a simpler method which could speed up the screening of suitable materials, using X-rays. The magnetic moment of an atom has two contributions, the spin part, which arises from the alignment of the intrinsic spin angular momentum of the electrons, and the orbital part,related to the coordinated orbital motion of the electrons. The former is the dominant source of the magnetic moment of the atoms in a solid, while the latter is usually found when spin-orbit coupling is active. However, a few years ago it was found that – even without spin-orbit coupling – an orbital moment can be finite. To make that happen, at least three magnetic atoms have to be combined, forming a trimer with a non-collinear and non-planar magnetic structure. A team of theoretical physicists from the Jülich Institute "Quantum Theory of Materials" (PGI-1/IAS-1) has now analysed the effect in detail for such magnetic trimers, and examined the consequences for skyrmions. The scientists propose a protocol on how to probe this contribution to the orbital magnetism, and furthermore, how to employ it to detect and distinguish different types of skyrmions. "One of the most important quantities characterizing the skyrmion is the topological charge, also known as the 'skyrmion number'", explains Dr. Manuel dos Santos Dias, Postdoc in institute's Young Investigators Group "Functional Nanoscale Structure Probe and Simulation Laboratory"(Funsilab). "A direct measurement of the topological charge has been difficult, as it requires a detailed map of the three-dimensional magnetic structure or finding certain signatures in transport experiments. Therefore, only very few experiments have been undertaken. Skyrmions with a richer internal structure have also attracted attention recently, and our proposed protocol naturally enables its experimental determination." Jun.-Prof. Samir Lounis, head of Funsilab, adds: "We propose a spectroscopic approach using X-ray magnetic circular dichroism to measure this quantity fast and efficiently. The technique could be implemented at any synchrotron covering the soft X-ray regime." Explore further: Team ahead of the 'curve' in magnetic study More information: Manuel dos Santos Dias et al.

Objective: To explore the correlation of student and faculty assessments of, second-year dental students' (D2s) communicative skills during simulated patient interviews. Methods: Eighty-two D2s, 14 student instructors and 8 faculty used a 5-point scale, (1 = poor-5 = excellent) to assess 12 specific communicative skills of D2s generating assessment sources of self, peer-group, student instructor, and faculty. Mean scores and comparisons between assessment sources were calculated. Spearman correlations evaluated relationships between specific skills and assessment sources. Results: Mean assessment score and standard error for peer-group (4.14 ± 0.04), was higher than self (3.86 ± 0.06, p< 0.05) yet slightly higher than student instructor (4.07 ± 0.04) and faculty (3.93 ± 0.10). Regarding assessment sources, the degree of correlation from highest to lowest was peer-group and student instructor (ρ=. 0.46, p< 0.0001), self and student instructor (ρ=. 0.35, p< 0.002), self and peer-group (ρ=. 0.28, p< 0.02). The correlations between student instructor and faculty, faculty and self, and faculty and peer-group were nonsignificant. Conclusion: Student assessments were different from faculty by mean score and correlation index. Future studies are needed to determine the nature of the differences found between student and faculty assessments. Practice implications: Peer, student instructor and faculty assessments of dental students' communicative skills are not necessarily interchangeable but may offer uniquely different and valuable feedback to students. © 2010.

Full potential-linearized augmented plane wave (FP-LAPW) method within density functional theory (DFT) was applied to study the structural and electronic properties of the magnesium arsenide in both cubic and hexagonal phases. The exchange-correlation functional was approximated as a generalized gradient functional introduced by Perdew-Burke-Ernzerhof (GGA96) and Engel-Vosko (EV-GGA). The lattice parameters, bulk modulus and its pressure derivative, cohesive energy, band structures and effective mass of electrons and holes (EME and EMH) were obtained and compared to the available experimental and theoretical results. A phase transition was predicted at pressure of about 1.63 GPa from the cubic to the hexagonal phase. The effect of hydrostatic pressure on the behavior of the electronic properties such as band gap, valence bandwidths, anti-symmetry gap (the energy gap between two parts of the valence bands), EME and EMH were investigated using both GGA96 and EV-GGA methods. High applied pressure can decrease (increase) the holes mobility of cubic (hexagonal) phase of this compound. © 2009 Elsevier B.V. All rights reserved.

First of all, the technological framework of the model for calculating the kill probability of multiple shots is established, followed by the corresponding calculation equations relating to two cases of both shooting errors and shooting index. For getting rid of the difficulties facing the calculation of kill probability of multiple shots, an approximate treating mode converting general shooting errors model into two-type errors model was adopted in the establishment of approximate equations used in mean point of impact method and average correlative coefficient method. The calculation equation for kill probability of multiple shots related to index was the first one established in that field, which has solved the difficult problem of calculating kill probability of multiple shots in the simulation and evaluation field of shooting efficiency of weapon systems. © 2015 IEEE.
