Solar water disinfection (SODIS) is an effective and inexpensive microbiological treatment technique, applicable to communities lacking access safely managed drinking services, however, the lower volume of treated per day (< 2.5 L batch) a limitation for conventional SODIS process. To overcome this limitation, continuous-flow solar system was developed tested inactivation Acanthamoeba castellan...

Scarf's Lemma originally appeared as a tool to prove the non-emptiness of the core of certain NTU games. More recently, however, several applications have been found in the area of graph theory and discrete mathematics. In this paper we present and extend some of these applications. In particular, we prove results on the existence of kernels in orientations of h-perfect graphs. We describe a ne...

Named entities form the major components in a document. When we catch the fundamental entities, we can understand a document to some degree. This paper employs different types of information from different levels of text to extract named entities, including character conditions, statistic information, titles, punctuation marks, organization and location keywords, speech-act and locative verbs, ...

This paper reports the work of NTU on bilingual-retrieval task at CLEF 2001. We proposed five models. Model 1 used co-occurrence information to disambiguate translation equivalents; Model 2 augmented restriction terms to the original queries; Model 3 used C-E WordNet to translate queries; Model 4 combined Model 3 with Model 2; Model 5 merged the queries constructed by Model 2 and 3. The best on...

This paper describes our speech enhancement and recognition systems developed for the Reverberation Challenge 2014. To enhance the noisy and reverberant speech for human listening, besides using conventional methods such as delay and sum beamformer and late reverberation reduction by spectral subtraction, we also studied a novel learning-based speech enhancement. Specifically, we train deep neu...

Industrial activities on the coast of Kali Mireng affect level water pollution. Pollution potential indicators describe quality. This study aims to determine quality coastal waters. The research was carried out in April-May 2021. We used chemical and physical parameters such as turbidity, pH salinity. temperature five stations with a minimum average value 270 C an maximum 30.70 C. salinity drin...
