We explain here, the wavelet based thresholding procedure, one of the key factors behind the successful application of wavelets
in image compression. We then elaborate on quantization and go on to outline the basic ideas underlying Huffman coding, the
other important tool for data compression. 相似文献

A highly reliable, quantitative and sensitive analytical method for determining the residues of the fungicide, hexaconazole in black tea is described. The proposed method is based on liquid-liquid extraction followed by gas chromatographic determination, using nitrogen phosphorus detector (GC-NPD) for the identification and quantitation of hexaconazole. The most was cleaned up by adsorption column chromatography using activated florisil. Performance of the method was assessed by evaluating quality parameters such as recovery value, repeatability, reproducibility, linearity and limits of detection and quantitation. When the method was assessed for repeatability, the percentage of recovery ranged between 86% and 96% while the relative standard deviation was between 0.30% and 2.35%. In studies on reproducibility the recovery ranged from 81% to 85% and relative standard deviation from 1.68% to 5.13%, implying that the method was reliable. A field trial was conducted to verify the application of this method with real samples. Results prove that the validated method was suitable for extracting hexaconazole residues. 相似文献

The purpose of this research article is to identify the critical success criteria/factors that affect the cloud computing adoption and examine structure, reliability and validity of the criteria in the SMEs industry. This study considers nine types of criteria/factors with fifty-one sub-criteria, which have somewhat previously been used, and creates a ranking model that offers decision makers to measure the prior implementation of cloud computing adoption. A questionnaire-based survey research was used to collect data from 110 firms belonging to the SMEs industry in India. In this paper, the data collected was analysed by an integrated approach. Firstly, an Analytic Hierarchy Process approach was applied to find the significant fact of each criterion as the assessable indices of the cloud computing adoption. Secondly, an Exploratory Factor Analysis and Confirmatory Factor Analysis were used to examine structure, reliability and validity of the criteria. The data was tabulated in a Microsoft Excel sheet and then imported in SPSS (Statistical Package for the Social Sciences version 20) for analysis. The findings discovered that ‘Security and Privacy’, ‘Organizational Risk’, ‘Sharing and Collaboration’, ‘Confidentiality’, and ‘Integrity’ have a major effect on the adoption of cloud computing. The research was conducted in the SMEs industry in India, which may limit the generalizability of the findings. The findings and recommendations offer cloud computing service providers as well as users with a better understanding of what affects the cloud computing adoption feature, with a relevant understanding of the current scenario. The research aided in the application of the new technology of cloud computing adoption in the SMEs industry in India through the use of a wide range of criteria. The findings also help organizations study their information technology investments when applying cloud computing. 相似文献

The Nobel Prize in Chemistry, 2012 has been awarded to Robert J Lefkowitz and Brian K Kobilka for their studies on G-Protein Coupled Receptors (GPCRs). GPCRs are receptor proteins present on the cell surface, which are involved in sensing molecules outside the cell and initiating a cellular response. They can sense a wide variety of ligands ranging from light to hormones and small peptides, triggering various physiological responses. Today we understand the molecular mechanisms by which these receptors work largely due to the contributions of Lefkowitz and Kobilka. Owing to the role of GPCRs in cell communication and involvement in various disease conditions, they are targets of over 40% of current drugs in the market. These findings have not only revealed how GPCRs work, but have also made a huge impact on the field of GPCR-associated drug discovery. 相似文献

Private for-profit higher education has grown rapidly in many parts of the world. This growth is attributed to many factors, including a broadening of the student population and the recognition that wider access to higher education will be economically beneficial to individuals, governments and society as a whole. In Australia, the number of students in private for-profit higher education is rising, with dramatic projections for the next 10 years. The Australian government has set a target to increase the participation of students in higher education, with a focus on increasing the access and success of students from disadvantaged backgrounds. It is unclear, however, what role the burgeoning private for-profit institutions will play in meeting the government's targets, and what incentives will be provided for them to increase the access and participation of students from disadvantaged groups. This paper analyses the key drivers of growth in private for-profit higher education in Australia, and discusses issues around quality and standards. It examines the strengths and limitations of the sector, and the extent to which it contributes to diversity, access and the participation of students from disadvantaged backgrounds. It argues that the sector needs clear government directions to improve levels of access, and new government policies to encourage public-private collaborations to help ensure sustainability. The paper also briefly touches on the need for a review into the current structure of Australia's higher education sector as a whole, and whether higher education would benefit from the formation of public community colleges with the explicit aim of widening access for disadvantaged student groups. Further, the paper suggests that encouraging such public-private collaboration may be beneficial to ensure access and participation of students from all walks of life, including disadvantaged groups. 相似文献

Modification of platelet proteins by free radicals and glycation has been studied in the present work, as anin vitro model. The results of the two parameters, SDS-PAGE and carbonylation study are quite corroborative. We observed that the
inducers like ferrous sulphate, ascorbate (mainly in supraphysiological concentration) and glucose attack the protein in a
dose dependent manner, of which ferrous sulphate is most potent. Proteins from aged and degenerative conditions like malignancy
and diabetes mellitus have suffered greater damage than normal adult and foetal proteins. The individual life expectancy in
terms of biological versus chronological age may also be worked out from the individual stress level. 相似文献

Determination of plasma total homocysteine by high-pressure liquid chromatography (HPLC) usually requires reduction of protein
bound or free homocysteine-disulphides into thiols by a reducing agent and the liberated thiols are then derivatized by a
fluorescent marker. In this study we have standardized the HPLC method for homocysteine measurement using dithiothreitol (DTT)
as reductant.
The results of plasma total homocysteine values obtained by HPLC were compared with IMx method. The difference between the
two means was statistically insignificant [P=0.616847 (two tail)] Linear regression analysis showed strong correlation between
the two methods (r=0.983). Using this method we have analyzed 132 controls and 130 Coronary Heart Disease (CHD) patients for
plasma total homocysteine, wherein, the mean plasma total homocysteine levels were 10.51±8.36 and 11.51±10.06 μmol/L respectively.
Our research study suggests that DTT method is a simple and inexpensive assay for homocysteine determination in human plasma
for research application. 相似文献
