In this paper, we proposed a stretchable radio frequency (RF) sensor to detect strain direction and level. The stretchable sensor is composed of two complementary split ring resonators (CSRR) with microfluidic channels. In order to achieve stretchability, liquid metal (eutectic gallium-indium, EGaIn) and Ecoflex substrate are used. Microfluidic channels are built by Ecoflex elastomer and microf...

The recently introduced notion of frame potential has proven useful for the characterization of finite-dimensional tight frames. The present work represents an effort to similarly characterize finite-dimensional tight frames with additional imposed structure. In particular, it is shown that the frame potential still leads to a complete description of tight frames when restricted to the class of...

In this paper, low latency and high throughput texture coding architectures are proposed to realize the 4×4 integer/Hadamard transforms, the quantization (Q), and the inverse-quantization (IQ) schemes for the H.264/AVC application. Based on matrix operations, the efficient fast two-dimensional (2-D) 4×4 transforms can be derived from the proposed one-dimensional (1-D) fast 4×4 transforms throug...

‎in this paper‎, ‎first we develop the duality concept for $g$-bessel sequences‎ ‎and bessel fusion sequences in hilbert spaces‎. ‎we obtain some results about dual‎, ‎pseudo-dual ‎and approximate dual of frames and fusion frames‎. ‎we also expand every $g$-bessel ‎sequence to a frame by summing some elements‎. ‎we define the restricted isometry property for ‎$g$-frames and generalize some resu...

Variable bit rate VBR video is expected to be a major source of tra c for the Broadband Integrated Services Digital Network B ISDN The MPEG coding scheme is one of the possibilities considered for the compression of video data In this paper a simple model for an MPEG coded video stream is developed which is used for the approximation of the cell loss rate at an ATM multiplexer bu er with MPEG v...

For a given class F of uniform frames of fixed redundancy we define a Grassmannian frame as one that minimizes the maximal correlation |〈fk, fl〉| among all frames {fk}k∈I ∈ F . We first analyze finite-dimensional Grassmannian frames. Using links to packings in Grassmannian spaces and antipodal spherical codes we derive bounds on the minimal achievable correlation for Grassmannian frames. These ...
