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...

The usage of hydrogen in fuel cells gains more and more importance due to the need for emission-low alternatives in various technical areas. The focus of this work lies on the polymer electrolyte membrane fuel cell. One ...

The problem of efficient signal communication at low data rates involves, in general, the encoding of the source for maximum data compression at the transmitter end, and the reconstruction using the received information ...

"Material Jetting technology has proven to be very useful in the manufacture of parts with a variety of shapes, consistencies, textures, transparencies and colours, and a great diversity of mechanical properties can be a...

Some theoretical studies abouth dynamic compression of powder aluminum are described. 3-D Finite elements of 27nodes are employed in spherical construction by flat circular plates. The first step is the testing of a prov...

"Aim of this article is to estimate and discuss the economic and environmental impacts for the obtainment of CO2 in such conditions to be injected as enhanced oil recovery (EOR) fluid. Particularly, this study focuses on...

The key problem in fractal image compression is that of obtaining the IFS code (a set of linear transformations)which approximates a given image with a certain prescribed accuracy (inverse IFS problem).In this paper,we a...

Formulaciones de amoxicilina 500 mg fueron desarrolladas por el método de compresión directa utilizando planeamiento factorial 23. Ocho formulaciones diferentes fueron planeadas y analizadas considerando tres niveles: ...

En el presente trabajo se estudió la influencia de la granulometría del diluyente-aglutinante (Avicel PH 101 o Avicel PH 102) y el tipo de lubricante (estearato de magnesio o ácido esteárico), mediante un diseño fac...

The purpose of development oral fast disintegrating drug delivery is not only to give fast relief but also to overcome difficulty in swallowing tablets and capsules, resulting in non-compliance and ineffective therapy. T...

The aim of the present investigation was to develop a modified release effervescent floating drug delivery system of famotidine for 12 h dosage regimen to improve its bioavailability. Effervescent floating tablets were...

In this paper two images compression techniques with loss based on the method used by the compression Standard Joint Photographic Experts Groups (JPEG) and on the Quadtree adaptive partitioning method are presented and c...

An Image Adaptive Watermarking method based on the Discrete Wavelet Transform is presented in this paper. The robustness and fidelity of the proposed method are evaluated and the method is compared to state-of-the-art w...

The present investigation concerns the development of floating tablets of tramadol hydrochloride, which after oral administration are designed to prolong the gastric residence time; improves the drug bioavailability, red...

The aim of the current study was the design, development and optimization of oral immediate release solid dosage forms of gliclazide tablets, intended for rapid action within 30 min, formulated and optimized by in vitro ...

Effervescent tablets have always been convenient, simple and measured dosage form. The phenomenon of carbonation, in this type of dosage form, accelerates the solubility and enhances the bioavailability of the drug and t...

To select the suitable concentration level of controlled release polymer for the formulation of predefined extended release formulation based on the solubility behaviour of active substance, we have formulated and evalua...

In a general context we introduce image processing with 1-dimensional wavelets and show the diferences with nonseparable 2-dimensional wavelets having quincunx decimation, in the first place, and with balanced nonseparab...

The purpose of the present study was to prepare spherical agglomerates (SA) of piroxicam by solvent change method. Crystallization medium used for spherical agglomerates of piroxicam consisted of DMF:water and chloroform...

In this work, we present a new lossy video compression scheme, based on the use of the 3D Fast Wavelet Transform (3D-FWT). This encoder achieves high compression ratio and a quality excellent from the point of medical vi...
