Light detection and ranging (LiDAR) has the capability of capturing a huge amount of highly accurate spatial data. However, the size of the data causes a lot of problems associated with its exchange and storage. In this paper, a method for lossless LiDAR data compression is presented. Although, efficient methods in terms of compression ratio have already been proposed, their time efficiency can...

      Extended release formulation of alfuzosin, an a-antagonist used for prostatic hypertrophy, is available in market. It is convenient for older patients to take only one tablet a day. Marketed alfuzosin formulation is three layered geomatrix tablet that requires special facilities, high cost, more time and complex operation than normal direct compression formulation. Therefore, a less compl...

Sequence representations supporting not only direct access to their symbols, but also rank/select operations, are a fundamental building block in many compressed data structures. In several recent applications, the need to represent highly repetitive sequences arises, where statistical compression is ineffective. We introduce grammar-based representations for repetitive sequences, which use up ...

The aim of this study was to prepare orally disintegrating tablets (ODTs) containingdexamethasone (DEX) by direct compression method with sufficient hardness and rapiddisintegration time. In order to save time, money, and human resources in designing andimprovement of formulation, the statistical software Design Expert is used. Box–Behnkenresponse surface methodology was applied to evaluate and...

percutaneous vertebroplasty is a promising therapeutic technique for pain control in patients with pathologic fractures of vertebral bodies. percutaneous vertebroplasty is an appropriate treatment for vertebral pathologic fractures, which is resistant to other usual treatment. it is a useful and only choice in special cases, because of less tissue damage and there is no risk of open surgery and...

The production technology of powder cellulose (Arbocel) and microcrystaline cellulose (Vivapur) and their application in the composition of direct compression tablet mass was provided. The function of silicified microcrystaline cellulose type Prosolv in the direct compression process of dry plant extract was discussed. An analysis of the chemical structure of cellulose fiber (Vitacel) enabled d...

Purpose: To determine excipient and ibuprofen:excipient mixture sensitivity to reprocessing produced by either direct compression or wet granulation. Methods: The effect of excipient type, technology and reprocessing on flow, compressibility and compactibility was assessed using and 8x2x2 factorial design. Design Expert® v.8.01 software was employed for data analysis. Pure excipients were proce...

Mouth dissolving tablets constitute an innovative dosage form that overcomes the problems of swallowing and provides a quick onset of action. In view of enhancing bioavailability an attempt has been made to study two different methods direct compression and sublimation in formulation of mouth dissolving tablets of clozapine. Total four formulations using various superdisintegrants and subliming...

This study investigated the effects of fast-acting hearing-aid compression on normal-hearing and hearing-impaired listeners' spatial perception in a reverberant environment. Three compression schemes-independent compression at each ear, linked compression between the two ears, and "spatially ideal" compression operating solely on the dry source signal-were considered using virtualized speech an...
