Abstract Voice compression is one of the important subject today specially in field of communication and application so in this paper, speech compression was adopted based on hybrid technique between wavelet and Huffman ...

In practical projects, structural fracture often undergoes complex stresses. The studies on the fracture mechanism of mixed mode cracks are of important theoretical significance and practical implication. Based on the mi...

ABSTRACT Objective While paraspinal muscle degeneration is closely linked to lumbar disc herniation (LDH), the relationship between radicular compression and paraspinal muscle degeneration remains controversial, and evid...

A data compression scheme suggested by Ziv and Lempel, LZ77, is applied to text compression. A slightly modified version suggested by Storer and Szymanski ,LZSS, is found to achieve compression ratios as good as most exi...

Abstract Medical images are inherently high-resolution and contain locally varying structures that are crucial for diagnosis. Efficient compression of such data must therefore preserve diagnostic fidelity while minimizin...

Background: Humeral shaft fractures account for approximately 3 % of all fractures and exhibit a bimodal age distribution. Dynamic compression plating (DCP) and locked compression plating (LCP) are two principal methods...

The research and studies of encryption and compression of digital files to the confidentiality and ease of dealing with networks and the Internet, by reducing the size of files transmitted through multimedia, and also us...

Post-processing evolution of the functional properties of soybean protein concentrate (SPC) films, plasticized with varying levels of glycerol and processed by compression molding, was examined over a period of 90 days. ...

Background/purpose: In pectus excavatum (PE) patients owing to the location of the heart in the chest cavity, the most affected site of compression by the depressed chest wall is the right heart, and surgical repair has ...

ABSTRACT Wood-cement composite (WCC) is a potential construction material for tropical regions, due to its physico-mechanical properties and resistance to decay and fungi attack. However it is important to test alternati...

Study objective: To evaluate whether impaired ventriculo-aretrial interaction characterizes chronic ischemic heart disease (CIHD) caused by stable chronic obstructive coronary artery disease (CAD), using wave intensity a...

In the present work, the synergistic effect of multiwalled carbon nanotubes and glycidyl polyhedral oligomeric silsesquioxanes on the compression after impact behaviour of multifunctional carbon fibre–reinforced epoxy ...

ABSTRACT The aim of this study was to develop a modified tibial plateau leveling osteotomy (TPLO) plate and to compare its biomechanical properties with a locking compression plate (LCP) and plate-rod constructs for the ...

In order to obtain the criteria and precursor characteristics of critical rock fracture, laboratory experiments on the characteristics of acoustic emission (AE) of gritstone specimens under uniaxial compression are carri...

Numerous seismic damage investigations have demonstrated that reinforced concrete (RC) frame structures tend to exhibit a Strong-beam Weak-column failure mechanism, which contradicts the intended Strong-column Weak-beam ...

The organic matter is an important symbol of peaty soil which is different from soft clay. The content of organic matter directly affects the physiochemical properties of peaty soil, and further affects its consolidation...

ABSTRACT Intervertebral disc degeneration (IVDD) is a leading global cause of low back pain, with abnormal mechanical stress being a central contributing factor. However, the molecular mechanisms through which mechanical...

Understanding how laser pulses compress solids into high-energy-density states requires diagnostics that simultaneously resolve macroscopic geometry and nanometer-scale structure. Here we present a combined X-ray imaging...

Abstract Objective To describe the clinical experience with the B-Lynch technique in the management of postpartum hemorrhage as well as the factors related to the indication of the technique and to present the success ...

Multiwavelets are new addition to the body of wavelet theory. There are many types of symmetric multiwavelets such as Geronimo-Hardin-Massopust (GHM) and Chui-Lian (CL) multiwavelets. However, the matrix filter generatin...

Data compression offers an attractive approach to reducing communication cost by using available bandwidth effectively. It also secures data during transmission for its encoded form. In this paper an index based position...

The aim of this work was to develop clozapine tablets that can be classified as a pharmaceutical equivalent to a reference brand product. Tablets were produced by direct compression and dissolution tests were realized ...

Video compression is one of the topics included in the area of images digital processing. The book gives an introduction to algorithms and architectures used in standard video and audio compression Facultad de Informáti...

Images compression is a widely studied topic. Conventional situations offer variable compression ratios depending on the image in question and, in general, do not yield good results for images that are rich in tones. Thi...
