ON SYMMETRIC BI-DERIVATIONS OF KU-ALGEBRAS

The notion of left-right (resp. right-left) symmetric biderivation of KU-algebras is introduced and some related properties are investigated

Relationship between Yarn Properties and Process Parameters in False-Twist Textured Yarn

The properties of false-twist textured yarns in the aspects of crimp characteristic and tensile behavior depend mainly on the draw ratio and the D/Y ratio. This study comprises investigations of the effect of D/Y ratio and draw ratio on the crimp and tensile properties and percent crystallinity. While there was no noticeable change on the percent crystallinity by altering these parameters, tenacity increased and crimp contraction decreased with increasing draw ratio, and crimp stability decreased when the D/Y ratio increased. K/S value also decreased with increasing draw ratio

WECIA Graph: Visualization of Classification Performance Dependency on Grayscale Conversion Setting

Grayscale conversion is a popular operation performed within image pre-processing of many computer vision systems, including systems aimed at generic object categorization. The grayscale conversion is a lossy operation. As such, it can signicantly in uence performance of the systems. For generic object categorization tasks, a weighted means grayscale conversion proved to be appropriate. It allows full use of the grayscale conversion potential due to weighting coefficients introduced by this conversion method. To reach a desired performance of an object categorization system, the weighting coefficients must be optimally setup. We demonstrate that a search for an optimal setting of the system must be carried out in a cooperation with an expert. To simplify the expert involvement in the optimization process, we propose a WEighting Coefficients Impact Assessment (WECIA) graph. The WECIA graph displays dependence of classication performance on setting of the weighting coefficients for one particular setting of remaining adjustable parameters. We point out a fact that an expert analysis of the dependence using the WECIA graph allows identication of settings leading to undesirable performance of an assessed system

The Mind Agents in Netlogo 3.1

In [Houk, 2005], the “Agents of the mind” idea is proposed as a suitable framework for studying the dynamics and complexities of mind. “Agents of the mind” is inspired by the society of mind idea of Marvin Minsky [Minsky, 1988]. According to the society of mind, the mind is a complex system. The mind agents are elusive to identify. The mind is proposed as a hierarchy of agents. The higher hierarchy agents compose of lower hierarchy agents. Higher level agents do not command lower level agents but they basically trigger or invoke lower level agents. Agents are functional entities and they interact with each other. One important part of the society of mind idea is that agents at the lowest level are the real workers. Higher level functionalities emerge as a result of the functioning of the lower level agents and the interactions between them. In agents of the mind project, computational distributed processing modules (DPM) are posited for corresponding anatomically defined assemblies and they are referred to as the agents of the mind. M1 is an anatomical area in the cerebral cortex which produces voluntary commands via its loops through basal ganglia and cerebellum. M1-DPM is a computational distributed processing module which simulates M1 area and its loops for voluntary commands production. We use Netlogo 3.1 agent-based programming environment to illuminate the properties of mind. In this work, the attractor network in cerebellar loop and the effects of Purkinje cell on production of motor commands have been studied. The results are reported in this paper

Social Appearance Anxiety in Adult Patients with Acne: A Cross-Sectional Study

The severity of acne may not directly reflect the psychological state of a patient. The aim of the present study was to evaluate the social appearance anxiety with overall morbidity in patients with acne. One hundred adult patients with acne and 67 age and sex-matched healthy controls were enrolled in the study. The patients and controls were asked to complete the Social Appearance Anxiety Scale (SAAS) and the General Health Questionnaire-12 (GHQ-12). Acne severity was evaluated objectively by the Global Acne Grading System (GAGS) and subjectively by the Visual Analogue Scale (VAS).  The mean score on SAAS (37.69±13.53; mean ± Standard deviation) was significantly higher than in the control group (32.48±9.34) (p=0.05). No significant difference was observed between the GHQ-12 scores of the acne (2.19±2.64) and the control group (1.63±2.2) (p=0.152). There was no correlation between the GAGS and the VAS (p=0.417). The SAAS scores of the patients with acne were correlated with the GAGS scores (p=0.05) but not correlated with VAS (p=0.481). The GHQ-12 scores were not correlated with GAGS (p=0.96) or with VAS (p=507). No statistical correlation was established between sex and the GAGS scores (p=0.385), SAAS scores (p=0.611), and GHQ-12 scores (p=0.196). The duration of acne was not correlated with SAAS scores (p=0.814) or with GHQ-12 scores (p=0.24). Social appearance anxiety is significant in adult patients with acne and it is correlated with objective acne severity. However, acne does not seem to be associated with substantial psychological distress or formal psychiatric disorder in adults.   </p
