K-d-frames and their duals [PDF]

Mathematica Moravica
In this paper, we define a linear bounded operator for double sequences and give a new generalization of frame called K-d-frame. We establish that K-d-frame is square summable in norm for finite dimensional separable Hilbert spaces and prove some results

RGB-D SLAM with Manhattan Frame Estimation Using Orientation Relevance

Sensors, 2019
Due to image noise, image blur, and inconsistency between depth data and color image, the accuracy and robustness of the pairwise spatial transformation computed by matching extracted features of detected key points in existing sparse Red Green Blue ...

A comparison between mesospheric wind measurements made near Christchurch (44°S, 173°E) using the high resolution doppler imager (HRDI) and a medium frequency (MF) radar [PDF]

Annales Geophysicae, 2000
We report on the comparison of winds measured by a medium frequency (MF) radar near Christchurch, New Zealand, and by the high resolution doppler imager (HRDI).

A new technique for evaluating mesospheric momentum balance utilizing radars and satellite data [PDF]

Annales Geophysicae, 2000
A new method for evaluating momentum balance in the mesosphere using radar and satellite data is presented. This method is applied to radar wind data from two medium frequency installations (near Adelaide, Australia and Christchurch, New Zealand) and ...

Frames generated by double sequences in Hilbert spaces [PDF]

Mathematica Moravica, 2023
In this paper, we introduce frames generated by double sequences (d-frame) in Hilbert spaces and describe some of their properties. Furthermore, we discuss frame operators, alternate dual frames and stability for d-frames.

Approximative K-atomic decompositions and frames in Banach spaces [PDF]

Arab Journal of Mathematical Sciences, 2020
L. Gǎvruţa (2012) introduced a special kind of frames, named K-frames, where K is an operator, in Hilbert spaces, which is significant in frame theory and has many applications.

Pionic and radiative transitions from $$T_{c\bar{s}0}^+(2900)$$ T c s ¯ 0 + ( 2900 ) to $$D_{s1}^+(2460)$$ D s 1 + ( 2460 ) as a probe of the structure of $$D_{s1}^+(2460)$$ D s 1 + ( 2460 )

European Physical Journal C: Particles and Fields, 2023
In this work, we evaluated the widths of the pionic and radiative transitions from the $$T_{c\bar{s}0}^{+}(2900)$$ T c s ¯ 0 + ( 2900 ) to the $$D_{s1}^{+}(2460)$$ D s 1 + ( 2460 ) in the $$D_{s1}^{+}(2460)$$ D s 1 + ( 2460 ) molecular frame and the $$D_{

Effects of using different materials at interface of trapezoidal reinforced concrete infilled frames–analytical and experimental approaches

Frontiers in Materials, 2023
Infilled frames are generally formed by the composite interaction between the frame and the infilled wall used for functional purposes. The composite interaction increases the in-plane lateral stiffness of the frame, which is considered an advantage ...

More Results On K-d-Frames

Journal of Mountain Research, 2023
In the present paper, we discuss about some more properties of K-d-frames and their duals in . We extend the concept of stability of the K-frame and tight K- frame under some perturbations for the double sequences. We also generalize the concept of quotient of bounded operator of K-frame. Furthermore, we show the relationship between the optimal bounds
