METHODS A cross-sectional survey was condcuted in 14 provinces (autonomous region, municipality) in China. A total of 47,325 adults aged⋝20 years were selected by multistage stratified sampling, and questionnaire survey and p...
Dalam penelitian ini, kami akan melaporkan pada segmentasi teks dokumen pidato bahasa Indonesia. Sebagai hasil dari penggunaan Automatic Speech Recognition (ASR), ditranskripsi menjadi tanpa batas untuk setiap dokumen. Dokumen-dokumen tersebut tentunya perlu disegmentasi sesuai dengan topiknya. Kami menerapkan metode TextTiling berbagai teknik pembobotan istilah seperti TF-IDF, TF-IDF-Mutual In...
In this work, the multifractal properties of hourly rainfall data recorded at a location in Southern Spain have been related to the scale properties of the corresponding intensity–duration–frequency (IDF) curves. Four parametric models for the IDF curves have been fitted to the quantiles of rainfall obtained using the generalized Pareto frequency distribution function with the extreme data seri...
For bounded datasets such as the TREC Web Track (WT10g) the computation of term frequency (TF) and inverse document frequency (IDF) is not difficult. However, when the corpus is the entire web, direct IDF calculation is impossible and values must instead be estimated. Most available datasets provide values for term count (TC) meaning the number of times a certain term occurs in the entire corpu...
The present work was conducted to investigate the coconut residue (CR) left after the extraction of coconut milk by subjecting it to physical treatments. Water-washed samples as well as the original samples were analyzed for their chemical composition, soluble dietary fiber (SDF), insoluble dietary fiber (IDF) and total dietary fiber (TDF), and measurements were based on dry matter. Fractionate...
The International Diabetes Federation Taskforce on Epidemiology and Prevention of Diabetes convened a consensus working group of diabetologists, endocrinologists, surgeons and public health experts to review the appropriate role of surgery and other gastrointestinal interventions in the treatment and prevention of Type 2 diabetes. The specific goals were: to develop practical recommendations fo...
OBJECTIVE To study the agreement among three distinct criteria for metabolic syndrome (MS) adapted to adolescents, and to identify associated factors for MS. METHODS Cross-sectional study with 65 obese subjects aged 10 to 18 years, attended to at the Outpatient Clinic for Obese Children and Adolescents at the Clinical Hospital of the Universidade Estadual de Campinas (Unicamp). MS was defined...
In many natural language processing (NLP) tasks, a document is commonly modeled as a bag of words using the term frequencyinverse document frequency (TF-IDF) vector. One major shortcoming of the frequencybased TF-IDF feature vector is that it ignores word orders that carry syntactic and semantic relationships among the words in a document, and they can be important in some NLP tasks such as gen...
Metabolic syndrome is a collection of abdominal obesity, hypertension, glucose intolerance and lipid abnormalities (elevated triglycerides, elevated LDL, and decrease the amount of HDL). The aim of this study is to investigate the prevalence of metabolic syndrome in people of Ahvaz according to IDF, ATPIII, Harmonized I and Harmonized II. A cross-sectional study with random cluster sampling in ...
OBJECTIVE To estimate the prevalence of the metabolic syndrome (MS) in a population of patients with overweight and obesity of the A Coruña and Granada health areas, using the definitions of the Third Report of the National Cholesterol Education Program Expert Panel on Detection, Evaluation and Treatment of High Blood Cholesterol in Adults (ATP III) and of the International Diabetes Federation ...
