As with any other database solution, graph databases also need to be able implement business rules related a given application domain. At the moment, aside from integrity constraints, there is limited number of mechanisms for implementation in Graph Database Management Systems (GDBMSs). The underlying property data model does not include formal notation on how represent different constraints. S...

the stolt (f-k) migration algorithm is a direct (i.e. non-recursive) fourier-domain technique based on a change of variables (or equivalently, a mapping) that converts the input spectrum to the output spectrum. the algorithm is simple and efficient but limited to constant velocity. a v(z)(f-k) migration method, capable of very high accuracy for vertical variations of velocity, can be formulated...

In this paper we develop a new approach for land leveling in order to improve the topology of a large area for irrigation or civil projects. The objective in proposed model is to minimize the total volume of cutting so that technical requirements of land leveling such as suitable slope and standard ratio of cutting to filling and maximum penstock point’s height are considered. We develop a warp...

in this study, an extended stress-based forming limit diagram (fld) for prediction of necking based on the marciniak and kucznski (m-k) model is represented and applied in tube hydroforming. the bulge forming of a straight tube is simulated by finite element method and verified with published experimental data. this adaptive simulation technique is based on the ability to detect the onset and g...

the proposed algorithm suggests a new method for determination of k/s value of primaries based on linear least squares technique. by applying the matrix pseudoinverse, a modification is introduced to eliminate the limitation on the numbers of applied dyes in one – constant kubelka-munk theory. the selection of dyes for tristimulus matching are also done on the basis of the initial spectrophotom...

This paper describes an effective unsupervised method for query-by-example speaker retrieval. We suppose that only one speaker is in each audio file or in audio segment. The audio data are modeled using a common universal codebook. The codebook is based on bag-of-frames (BOF). The features corresponding to the audio frames are extracted from all audio files. These features are grouped into clus...

In the paper we claimed that teleportation with |tn〉 satisfies that if 0 < k < n + 1, then the teleported state appears in mode n + k and only needs to be corrected by applying a phase shift. The modes 2n − l are in state 1 for 0 ≤ l < (n − k) and can be reused in future preparations requiring single photons. The modes 2n − l are in state 0 for n − k < l < n. If k = 0 we learn that the input st...
