This study compared the use of three sensory and analytical techniques: Quantitative Descriptive Analysis (QDA), Napping, Gas Chromatography-Mass Spectrometry (GC-MS) for assessment flavour in nine unmatured whisky spirits produced using different yeasts. Hierarchical Multiple Factor (HMFA) showed a similar pattern sample discrimination (RV scores: 0.895–0.927) across were mostly separated by t...

Rice bran is known to have beneficial nutrients. Current studies suggest that solid-state fermentation affects the rice bran’s volatile profile. The aim of this study identify compounds and aroma description fermented nonfermented (FRB NFRB) Ciherang, Inpari30, IR64 Inpari42. was conducted using Rhizopus oligosporus fermentation. Headspace-solid phase microextraction coupled with GC/MS performe...

This article presents the QDA-System (Sistema Qualidade da Água, from Portuguese), a system developed to monitor quality of surface waters in Brazilian hydroelectric reservoirs using satellite images and cloud computing services. The development requirements considered its use for operational monitoring purposes, with all processing steps automated, user-friendly interface access query data gen...

this paper presents a system aimed to be entirely located in the Internet. The database, server side, logic and user interface are accessible regardless the location and equipment of the working team members. The system supports qualitative analysis of large datasets, and the work can be distributed among several team members or teams. A modified mixed method for developing software projects is...

■ ■ The ACQUITY QDa Mass Detector provides sensitive and selective determination of UV transparent sweeteners. INTRODUCTION Sugars are renowned for their sweet taste and are often added to manufactured foods to enhance human perception of flavor. Due to the negative health effects of excessive consumption of sugar, alternative non-nutritive sweeteners are commonly used in food and beverage prod...

Gender detection is a very important objective to improve efficiency in tasks as speech or speaker recognition, among others. Traditionally gender detection has been focused on fundamental frequency (f0) and cepstral features derived from voiced segments of speech. The methodology presented here consists in obtaining uncorrelated glottal and vocal tract components which are parameterized as mel...

In this paper, the performance of different generative methods for the classification of cervical nuclei are compared in order to detect cancer of cervix. These methods include classical Bayesian approaches, such as Linear Discriminant Analysis (LDA), Quadratic Discriminant Analysis (QDA) or Mixture Discriminant Analysis (MDA) and a high-dimensional approach (HDDA) recently developed. The class...

Abstract Human milk (HM) of healthy, well-nourished, lactating mothers is a unique and ideal source nutritive factors, like hormones, cytokines, chemokines, growth factors that ensures the proper development infants. Among main components HM, fat an important energy regulatory factor. The quality depends on its fatty acid (FA) composition. Gas chromatography coupled with flame ionisation detect...

BACKGROUND AND OBJECTIVE Injury of knee joint cartilage may result in pathological vibrations between the articular surfaces during extension and flexion motions. The aim of this paper is to analyze and quantify vibroarthrographic (VAG) signal irregularity associated with articular cartilage degeneration and injury in the patellofemoral joint. METHODS The symbolic entropy (SyEn), approximate ...
