In AfricaCrypt 2012, several algorithms are proposed for the batch verification of ECDSA signatures. In this paper, we propose three randomization methods for these batch-verification algorithms. Our first proposal is based on Montgomery ladders, and the second on computing square-roots in the underlying field. Both these techniques use numeric arithmetic only. Our third proposal exploits symbo...

This study presents findings on an assessment of the effect of continuous and batch feeding strategies on the removal of selected pharmaceuticals from synthetic wastewater. Six mesocosm-scale constructed wetlands, including three horizontal subsurface flow constructed wetlands and three sand filters, were set up at the campus of Nanyang Technological University, Singapore. The findings showed t...

background sugar alcohol erythritol is a non-caloric sweetener, non-cariogenic, and safe for diabetics because of no change to blood glucose and insulin levels after oral administration. erythritol cannot be degraded by any enzymatic systems and must be eliminated from the blood through the kidney. objectives: the aim of this study was production and optimization of erythritol from glucose by y...

conclusions the findings of the current study indicate that at high concentrations of salt, the growth of bacteria reduces so that it stops at a concentration of 50 mg l-1 (5%). thus, the bacterium is halotolerant or halophilic. with an increase in phenol concentration, the growth rate increased. phenol toxicity appears at a concentration of 600 mg l-1. results the phenol concentration of 600 m...

We describe synchroton based X-ray diffraction techniques and issues related to in situ studies of intercalation processes in battery electrodes. We then demonstrate the utility of this technique, through a study of two batches of LiMn2O4 cathode materials. The structural evolution of these spinel materials was monitored in situ during the initial charge of these electrodes in actual battery ce...

Processes of a real world manufacturer involve a number of batch-processing operations. Generally, these operations require the decision on batch sizes of products and there is no specific rule to set batch sizes of all products simultaneously so that the sum of the weighted expected cycle times of all products is minimized. The weights represent different levels of importance for products. In ...

Purpose – The purpose of this article is to describe a workflow of automated batch loading metadata from existing text to a database. Methodology/Approach – It introduces a case for the experience of metadata creation at Rutgers University Libraries in a collaborative digital project with the Hoboken Public Library in New Jersey. Findings – It is found that a well-designed workflow is crucial t...

A dynamic shortest-path algorithm is called a batch algorithm if it is able to handle graph changes that consist of multiple edge updates at a time. In this paper we focus on fully-dynamic batch algorithms for single-source shortest paths in directed graphs with positive edge weights. We give an extensive experimental study of the existing algorithms for the single-edge and the batch case, incl...

This paper deals with the design of observers for batch processes and the tuning of the observer gains with the objective to guarantee fast convergence of the state estimates. The approach followed in the present proposes to use an ITSE (Integral of the Time-weighted Square Error) criterion. The approach is illustrated on a batch process used in wastewater treatment, sequencing batch reactor (S...
