Stack-run adaptive wavelet image compression
We report on the development of an adaptive wavelet image coder based on stack-run representation of the quantized coefficients. The coder works by selecting an optimal wavelet packet basis for the given image and encoding the quantization indices for significant coefficients and zero runs between coefficients using a 4-ary arithmetic coder. Due to the fact that our coder exploits the redundancies present within individual subbands, its addressing complexity is much lower than that of the wavelet zerotree coding algorithms. Experimental results show coding gains of up to 1:4dB over the benchmark wavelet coding algorithm

Characterizing Information Propagation in Plants
This paper considers an electro-chemical based communication model for
intercellular communication in plants. Many plants, such as Mimosa pudica (the
"sensitive plant"), employ electrochemical signals known as action potentials
(APs) for communication purposes. In this paper we present a simple model for
action potential generation. We make use of the concepts from molecular
communication to explain the underlying process of information transfer in a
plant. Using the information-theoretic analysis, we compute the mutual
information between the input and output in this work. The key aim is to study
the variations in the information propagation speed for varying number of plant
cells for one simple case. Furthermore we study the impact of the AP signal on
the mutual information and information propagation speed. We aim to explore
further that how the growth rate in plants can impact the information transfer
rate and vice versa.Comment: 6 pages, 5 Figures, Submitted to IEEE Conference, 201
PDF Estimation and Liquid Water Content Based Attenuation Modeling for Fog in Terrestrial FSO Links
Terrestrial Free-space optical communication (FSO) links have yet to achieve a mass market success due to the ever elusive 99.999% availability requirement. The terrestrial FSO links are heavily affected by atmospheric fog. To design systems which can achieve high availability and reliability in the presence of fog, accurate and better models of fog attenuation need to be developed. The current article puts forth appropriate probability density function estimates for received signal strength (hereafter RSS) under fog conditions, where variations in the RSS during foggy events have been statistically characterized. Moreover, from the surface observations of fog density, liquid water content (hereafter LWC) of fog is estimated. The actual measured optical attenuations are then compared with the optical attenuations estimated from LWC. The results presented suggest that fog density measurements carried out are accurate representation of the fog intensity and the attenuation predictions obtained by the LWC estimate match the actual measured optical attenuations. This suggests that the LWC is a useful parameter besides visibility range to predict optical attenuations in the presence of hydrometeors
Evaluation of social personalized adaptive E-Learning environments : end-user point of view
The use of adaptations, along with the social aļ¬ordances of collaboration and networking, carries a great potential for improving e-learning experiences. However, the review of the previous work indicates current e-learning systems have only marginally explored the integration of social features and adaptation techniques. The overall aim of this research, therefore, is to address this gap by evaluating a system developed to foster social personalized adaptive e-learning experiences. We have developed our ļ¬rst prototype system, Topolor, based on the concepts of Adaptive Educational Hypermedia and Social E-Learning. We have also conducted an experimental case study for the evaluation of the prototype system from diļ¬erent perspectives. The results show a considerably high satisfaction of the end users. This paper reports the evaluation results from end user point of view, and generalizes our method to a component-based evaluation framework
The Influence of Product Quality, Prices and Promotions on Interest in Buying Sri Sulastri's Batik
This study aims to determine the effect of product quality, price and promotion of buying interest in Sri Sulastri's Batik of Bantul Yogyakarta. Type of research that used was quantitative research with survey methods. Sample in research was 100 customers who visited the Sri Sulastri's Batik Bantul Yogyakarta. Collection data methods used a questionnaire. Data analysis used multiple linear regression test. The results of the analysis show, 1) the quality of the product has influential positive and significant effect on buying interest in Sri Sulastri's Batik Bantul Yogyakarta, 2) price has positive and significant effect on buying interest in Sri Sulastri's batik Bantul Yogyakarta, 3) promotion has a positive and significant effect on the interest in buying Sri Sulastri's batik Bantul Yogyakarta, 4) coefficient of determination (R2) obtained for 0.536, which means that 53.6% of the product quality, price and promotion variables explain the variance of interest in buying interest, the remaining 46.44% is explained by other variables.Conclusion that product quality, price and promotion have an effect on buying interest Sri Sulastri's Batik Bantul Yogyakarta.
Keywords: product quality, price, promotion, buying interes
