The hidden terminal problem is a well-known problem in wireless networks that degrades the network performance due to collisions between nodes unable to sense each other. Preamble sampling WSNs are more sensitive to that problem than wireless local area networks due to the high vulnerability time caused by the long preamble transmission. This is specially important when the traffic load is high...

Paralytic Shellfish Toxins (PSTs) are highly toxic metabolic by-products of cyanobacteria and dinoflagellates. The filamentous cyanobacterium Lyngbya wollei produces a unique set of PSTs, including L. wollei toxins (LWT) 1-6. The accurate identification and quantification of PSTs from Lyngbya filaments is challenging, but critical for understanding toxin production and associated risk, as well ...

Due to the development of the Internet, security and intellectual property protection have attracted significant interest in the copyright protection field recently. A novel watermarking scheme for breath sounds, combining lifting wavelet transform (LWT), discrete cosine transform (DCT), singular value decomposition (SVD) and dither modulation (DM) quantization is proposed in this paper as a wa...

Digital image watermarking is proposed using lifting wavelet transform and singular value decomposition for copyright protection and authentication. In this paper, lifting wavelet transform (LWT) transforms the image into subbands. The subband having energy greater than computed ‘Q’ value is selected for watermark embedding. Singular value decomposition (SVD) matrix is derived for this subband ...

A new method for the implementation of the binary-tree decomposition of the convolution-based wavelet transform, called the Local Wavelet Transform (LWT) has been recently proposed in the literature. While it produces exactly the same results as the classical row-column implementation of the transform, it has many implementation benefits. In this paper, this fact is shown experimentally for the...

In ultrasonic testing of welding flaws, the reliability and quality of tests are considerably affected by noise and spurious signals. Thus, signal de-noising and increasing of the signal-noise ratio (SNR) are a key to successful application of ultrasonic NDT and NDE. At present, there are many methods for signal de-noising, such as median filtering, non-linear filtering, adaptive filtering, cor...

A new lossless scalable coding based on a lossless wavelet transform (LWT) and a lossless multi-channel prediction (LMP) is proposed. A rough image can be expanded from a part of the bit stream for the use of progressive transmission. The LMP, a non-separable 2D filter bank, is optimized for an arbitrary input image signal so that remaining correlation of the band signals of the LWT can be util...

Slaughter and carcass data were obtained on 197 bulls produced in a diallel involving Angus, Brahman, Hereford, Holstein and Jersey that were slaughtered at either 6, 9, 12, 15, 18, 24, or 30 mo of age. Bulls were given ad libitum access to a 72% TDN diet on an individual basis from 6 mo of age until slaughter. Empty body weight (EBWT) was determined as the sum of the weights of blood, hide, ha...

A common problem experienced in datacenters and utility clouds is the lack of knowledge about the mappings of the services being offered to or run by external users to the sets of virtual machines (VMs) realizing them. This makes it difficult to manage VM ensembles to attain provider goals like minimizing the resources consumed by certain services or reducing the power drawn by datacenter machi...

PURPOSE To investigate the 10-year survival and complication rates of Morse taper connection implants (MTCIs) placed in grafted sinuses. METHODS This study reports on patients treated with maxillary sinus augmentation (with the lateral window technique (LWT) or the transalveolar osteotomy technique (TOT)) and installed with MTCIs supporting fixed restorations (single crowns (SCs) and fixed pa...
