It is very important for generating an orthonormal multiwavelet system to construct a conjugate quadrature filter (CQF). In this paper, a general method of deriving a length-J + 1 conjugate quadrature filter with multiplicity r and scale a from a length-J conjugate quadrature filter is obtained. As a special case, we study generally the construction of a length-J + 1 conjugate quadrature filter which...
An efficient algorithm for solving Fredholm systems is proposed with operational matrices of integration of Haar wavelets. Numerical experiments demonstrate that the approximate solutions obtained by the presented algorithm have wonderful agreement with the analytical solutions and tend to be more accurate with the increase of the order of the Haar wavelet.
Active database rules provide event management capability to database systems by signaling events and handling events automatically. Active rules play important roles in data management such as database integrity checking and database integration. Our past research has reported an active rule scheduling algorithm, named IRS, to schedule the execution of concurrently triggered rules to achieve the...
Force information in virtual space is important and often required for tele-operation, training, amusement, design supporting, and other virtual reality systems. The application of passive-type force display and rehabilitation system is desirable for its high safety. However, there are some directions and link positions for which it is difficult to display the force using only passive elements. To...
As an important part of requirement management, managing requirement change plays a key role in controlling project schedule and costs at early stage. Effective requirement impact analysis would give proper assessment on the effect of certain requirement changes on the whole system, and provide useful information for making trade-off decisions on future system design and implementation. In this paper...
In order to monitor the cosmic radiation exposure level onboard aircraft in accordance with the national standard about radiation safety, a computer system CARD has been developed using to calculate cosmic radiation effective dose in flight. In this paper, the principle of development, structure and function of the CARD were described. The cosmic radiation effective doses received by aircrews in flight...
Several 2-DOF rehabilitation robots for upper limbs have been proposed so far, and clinical effectiveness was reported in several studies for the aged people or patients with stroke. We developed the quasi 3-DOF rehabilitation system ldquoHybrid PLEMOrdquo which has 2-DOF force-feedback function in working plane but its working plane can be adjusted the inclination. Hybrid-PLEMO is a compact, low-cost...
SCR is a mature and widely used document driven requirement method, which emphasizes creating strict and complete formal requirement documents during software requirement analysis to serve the whole life circle. However, due to the big gap between textual requirement description and formal requirement document, how to obtain formal SCR requirements specification from informal textual description becomes...
Normal myometrial tissues, hysteromyoma and endometrial carcinoma were determined by horizontal attenuated total reflectance Fourier transform infrared spectroscopy (HATR-FTIR) directly and fast. The results showed that there are obvious and regularity differences HATR-FTIR spectra of them in spectral parameters such as frequency, intensity and shape of the bands. They indicated significant differences...
