In order to evaluate the effects of both cold and light stresses on chlorophyll fluorescence and feasibility of using chlorophyll florescence technique to evaluate effect of light intensity on cold tolerance in soybean, an experiment was done in a factorial arrangement based on a completely randomized design with three replicates. Two soybean cultivars consisted of 032 and BP grown under greenh...
This paper proposes a multiplierless VLSI architecture for the famous 9/7 wavelet filters. The novelty of this architecture is the possibility to compute the 5/3 wavelet results into the 9/7 data-path with a reduced number of adders compared to other solutions. The multiplierless architecture has been characterized in terms of performance through simulations into a JPEG2000 environment and comp...
This paper shows that income shocks to rural households have permanent effects on the educational attainment of 7-15 year old children within the household. Using a 13 year panel survey of households in rural Tanzania, I find that idiosyncratic crop shocks such as pests, theft and fire cause changes in the distribution of schooling among children within the household that persist 10-13 years af...
In Wireless Multimedia Sensor Networks, the amount of multimedia traffic generated by the source nodes and relayed throughout the network towards the sink nodes is relatively vary large. As a result, the overall network performance and operational lifetime rely heavily on the efficiency and the complexity of the compression techniques used. However, known compression techniques have either high...
As wavelet-based image coding is set to become more widely used (e.g. with the completion of the JPEG2000 standard), memory efficiency for wavelet-based coding is becoming an increasingly important issue. In this paper we present a complete system to perform low memory wavelet image coding. Our approach is “line-based” in that the images are read line by line and only the minimum required numbe...
This article gives an overview on how different components developed by the SCAPE project are intended to be used in composite file format migration workflows; it will explain how the SCAPE platform can be employed to make sure that the workflows can be used to migrate very large image collections and in which way the integration with a digital object repository is intended. Two institutional i...
