  • The cathodic reduction of nitrate and nitrite ions on a copper electrode in aqueous potassium chloride solutions was studied using cyclic voltammetry technique. The cyclic voltammograms showed that nitrate and nitrite ion reduction occurred in the 0.14 M KCl solution with peak potentials of -1.25 to -1.30 V and -1.20 to -1.25 V (Ag/AgCl) respectively.

  • Linear Context-Free Rewriting Systems (LCFRSs) are a grammar formalism capable of modeling discontinuous phrases. Many parsing applications use LCFRSs where the fan-out (a measure of the discontinuity of phrases) does not exceed 2. We present an efficient algorithm for optimal reduction of the length of production right-hand side in LCFRSs with fan-out at most 2. This results in asymptotical running time improvement for known parsing algorithms for this class.

  • For ambiguous sentences, traditional semantics construction produces large numbers of higher-order formulas, which must then be -reduced individually. Underspecified versions can produce compact descriptions of all readings, but it is not known how to perform -reduction on these descriptions. We show how to do this using -reduction constraints in the constraint language for -structures (CLLS). They are based on dominance constraints (Marcus et al., 1983; Rambow et al., 1995) and extend them with parallelism (Erk and Niehren, 2000) and binding constraints. ...

  • Statistical machine learning methods are employed to train a Named Entity Recognizer from annotated data. Methods like Maximum Entropy and Conditional Random Fields make use of features for the training purpose. These methods tend to overfit when the available training corpus is limited especially if the number of features is large or the number of values for a feature is large. To overcome this we proposed two techniques for feature reduction based on word clustering and selection.

  • This paper proposes the use of uncertainty reduction in machine learning methods such as co-training and bilingual bootstrapping, which are referred to, in a general term, as ‘collaborative bootstrapping’. The paper indicates that uncertainty reduction is an important factor for enhancing the performance of collaborative bootstrapping.

  • We also present a variant of the algorithm that performs modular multiplication by interleaving the shift-and-add and the modular reduction steps. The modular multiplication algorithm can be used to obtain efficient VLSI implementations of exponentiation cryptosystems.

  • Among the solutions, a solution economists and government agencies have mentioned recently is to strengthen the role of FDI to poverty reduction. This will make the process of poverty reduction more active as the poor are not only waiting for government subsidies but also escaping poverty actively with their greatest asset: their labor.

  • Since Đổi mới (Renovation) was initiated by the Communist Party of Vietnam for the first time in 1986, both theoretically and practically significant achievements have been gained in all economic, political, social and cultural fields. One of the most outstanding achievements is the development of the Party’s and the State’s awareness and thinking on social justice and poverty reduction. The paper presents the development stages through major landmarks of Đổi mới in our country.

  • The purpose of this state of the art review is to assess what is currently assumed and believed about the relationship of skills development to poverty reduction, and to place that in historical perspective. There will be a particular attempt, where possible, to examine what is known about skills in rural areas. This task is made more complex by the fact that both ‘skills development’ and ‘poverty reduction’ are neologisms; they have not been in common parlance for much more than a decade.
