Cayenne pepper productivity in Bali Province tend to decline predicted caused by the traditionally cayenne cultivation applied farmers related. One of effort optimize is implementation Integrated Crop Management (ICM) technology cultivation. ICM can be introduced related technical guidance method at early stage. The goal its was find out changes farmer’s knowledge and attitude Study conducted K...
ABSTRACT Purpose: to analyze the speech-language-hearing therapists’ perception of structured tests proposed by current Chilean regulations assess and diagnose language in children. Methods: a questionnaire their three (the Test Auditory Comprehension Language, revised Phonological Simplification Processes Assessment Screening Spanish Grammar). Differences were contrasted with Friedman test, po...
In cancer chemoprevention studies, the identification of better antitumor-promoting agents is highly desired because they may have a wider applicability against the development of clinical cancers. Both epidemiological and animal studies have suggested that microchemicals present in the diet and several herbs and plants with diversified pharmacological properties are useful agents for the preve...
Obstructive sleep apnea syndrome (OSA) and restless legs syndrome (RLS) with periodic limb movement during sleep (PLMS) are two sleep disorders characterized by repetitive respiratory or movement events associated with cortical arousals. We compared the cerebral hemodynamic changes linked to periodic apneas/hypopneas with arousals (AHA) in four OSA-patients with periodic limb movements (PLMA) w...
The Wilcoxon signed rank test is a frequently used nonparametric test for paired data (e.g., consisting of pre- and posttreatment measurements) based on independent units of analysis. This test cannot be used for paired comparisons arising from clustered data (e.g., if paired comparisons are available for each of two eyes of an individual). To incorporate clustering, a generalization of the ran...
Bayesian methods are ubiquitous in machine learning. Nevertheless, the analysis of empirical results is typically performed by frequentist tests. This implies dealing with null hypothesis significance tests and p-values, even though the shortcomings of such methods are well known. We propose a nonparametric Bayesian version of the Wilcoxon signed-rank test using a Dirichlet process (DP) based p...
In this paper, we propose an intelligent scheme and design a spatial information sampling algorithm (SIS) to achieve balance between exploitation exploration more efficiently. SIS, by creatively using chaotic map, divide the population of into external internal parts activate corresponding or operations according location where optimal individuals appear in population. The makes full use soluti...
Abstract The paper addresses the limitations of Moth-Flame Optimization (MFO) algorithm, a meta-heuristic used to solve optimization problems. MFO which employs moths' transverse orientation navigation technique, has been generate solutions for such However, performance is dependent on flame production and spiral search components, mechanism could still be improved concerning diversity flames a...
The Wilcoxon one-sample signed rank test may be used to test whether a particular sample came from a population with a specified median. It is assumed that the population distribution is symmetric. The data consists of a single sample of n observations denoted by x1; x2; . . . ; xn. This sample may arise from the difference between pairs of observations from two matched samples of equal size ta...
The exponentially weighted moving average (EWMA) control chart is a memory-type known to be more efficient in detecting small and moderate shifts the process parameter. double EWMA (DEWMA) an extension of that effective than latter detection small-to-moderate shifts. This paper proposes new distribution-free (or nonparametric) triple (TEWMA) based on Wilcoxon rank-sum (W) statistic improve abil...
