Image Segmentation Using Fuzzy-Spatial Taxon Cut

Images convey multiple meanings that depend on the context in which the viewer perceptually organizes the scene. This presents a problem for automated image segmentation, because it adds uncertainty to the process of selecting which objects to include or not include within a segment. I’ll discuss the implementation of a fuzzy-logic-natural-vision-processing engine that solves this problem by assuming the scene architecture prior to processing. The scene architecture, a standardized natural-scene-perception-taxonomy comprised of a hierarchy of nested spatial-taxons. Spatial-taxons are regions (pixel-sets) that are figure-like, in that they are perceived as having a contour, are either `thing-like\u27, or a `group of things\u27, that draw our attention. Defined in this way, the image segmentation problem can be operationalized into a series of iterative two-class fuzzy inferences. Spatial-taxon cut is determined operationally, by simultaneously minimizing of attentional resources and maximizes of utility. This system provides a top-down computer vision model of scene organization

Translation quality assessment : an application of a rhetorical model

Translation quality assessment is a fast growing sub-field ofTranslation Studies. It focuses on the inter-relationships between thetext translated from (ST) and the text translated into (TT). Theseinter-relationships involve the lexis, grammar, syntax, and semanticsof both texts. Unlike sentences in isolation, texts are context-bound.Distinctions between text and sentence are made. Text-boundtranslation can only be conducted and assessed within the domain oftext-linguistics.Assessment of translation quality should be based on a definable,applicable, and testable model which, in turn, should be based on asound, comprehensive theory of translation. Current models fortranslation emphasite one aspect against other aspects. For instance,the grammatical model focuses on the linguistic aspect of translation.The cultural model, on the other hand, highlights the communicativeaspect whereas the interpretive model concentrates on the pragmaticaspect of translation. Such artificial compartmentalization is aliento the nature of translation. As a process translation, in fact,involves the integrated synthesis of the above aspects.This theris presents a model for translation quality assessmentbased on a sound theory of translation which comprehends thephilosophical (pragmatic), communicative (cross-cultural), and semiotic(linguistic) aspects of langauge. Since translation is a semantic entity, our model - which we label 'rhetorical' - focuses on theconcept of 'meaning shifts' according to which the meaning of a text isclassifiable into obligatory, extended, and accessory meanings. Thisdoes not suggest that the semantic structures of a text exist in astate of utter un-relatedness. On the contrary, they survive in theform of inter-related layers within the macro-structure of the text.The relative dominance of any of the three meaning categoriesdetermines the type of text.According to this model, texts are broadly classified intoliterary, non-literary, and hybrid texts. In a literary text, extendedand accessory meanings abound leaving a tiny room for obligatorymeaning. In non-literary texts, on the other hand, extended andaccessory meanings recede to the background leaving the obligatorymeaning in the foreground. In hybrid or fuzzy texts, semanticstructures are disproportionately distributed with no dominance of anyspecific category. The topic and scope of a hybrid text determine thevolume of extended and accessory meaning in relation to obligatorymeaning.The model is not intended for translation quality assessment only.It has pedagogical implications as well. Translation students andtrainees can implement this model in textual analysis before theyembark on the process of translation. Phonological, grammatical,syntactic, semantic, and lexical correspondences between SL and TL texts are identified before assessment of translation quality isestablished

Diseño de un proceso de nitrificación y desnitrificación para una Edar

Treball Final de Grau en Enginyeria Química. Codi: EQ1044. Curs acadèmic: 2020/2021En el presente Trabajo Fin de Grado se realiza un estudio para modificar el tratamiento biológico presente en la planta depuradora de aguas residuales de Benicasim. El tratamiento biológico actual en la planta está formado por dos reactores situados en paralelo, con un volumen útil de 1320 m3 entre los dos y el caudal medio de diseño del tratamiento biológico es de 6.000 m3/d. La modificación que se realiza en este proyecto consiste en separar cada uno de estos reactores en tres etapas, cada una de las cuales formadas por una zona anóxica seguida de una zona aerobia, de tal manera que se consiga por medio de un proceso de nitrificación y desnitrificación disminuir la concentración de nitrógenos y de materia orgánica presente en la corriente de agua residual. Además, la alimentación a cada uno de los reactores será distribuida entre las zonas anóxicas de las diferentes etapas. Con este diseño, se busca cumplir los valores límites de emisión dictados por la Ley para poder verter el agua residual en su cauce natural sin perjudicar al ecosistema. Para llevar a cabo el proyecto de la mejor manera posible, se ha realizado en primer lugar los cálculos de diseño para dos temperaturas diferentes (para la época de verano y la época de invierno) partiendo de las características del agua residual que llega a la planta. A continuación, se ha determinado la demanda de oxígeno y el número de difusores necesario en cada reactor aerobio, se ha diseñado las tuberías y por medio de un balance de energía mecánica se ha determinado la cantidad de bombas necesarias que hay que instalar en el diseño y la potencia necesaria de cada una. Seguidamente se han realizado los planos en AutoCAD y por último se ha hecho un estudio de viabilidad económica y de seguridad y salud

Effectiveness of employing fixed infographic in acquiring technological concepts for 7th grade students

The research aimed to explore the effectiveness of employing fixed infographic in acquiring technological concepts for 7th grade students. The sample of the research consisted of (84) students from the seventh-grade primary in the Saad bin Abi Waqas Primary School in the Palestinian Ministry of Education. The study is built on the experimental approach (control group and experimental group), in which the researchers applied testing the technological concepts on the research sample as a research tool. The results of the research revealed statistical significant differences between students’ mean scores of post application test in the experimental group and in the control group in favor to the experimental group. The research recommends the necessity of employing fixed infographics in teaching some subjects, developing different types of thinking and performance skills, and directing and sensitizing the educational staff and the educational administration to the importance of employing and using infographics in the educational process

Antioxidant and antimicrobial effect of alkaloid bulbs extract of Polianthes tuberosa L. (Amaryllidaceae) cultivated in Algeria

Polianthes tuberosa L. (Amaryllidaceae) is an ornamental and medicinal plant. Its flowers and bulbs are used traditionally as a diuretic, emetic, against rashes and gonorrhea. The aim of this work was, to evaluate the antioxidant and antimicrobial activities of bulbs and bulbils alkaloid extracts of P. tuberosa. Antiradical effect was assessed against DPPH radical. However, antimicrobial activity was measured through the disc diffusion method against Escherichae coli ATCC 25922, Pseudomonas aeruginosa ATCC 27853, Staphylococcus aureus ATCC 25923, Enterococcus faecalis ATCC 29212, Staphylococcus aureus resistant to Methicillin (MRSA) and Candida albicans ATCC 90028. The scavenging effect against DPPH showed that the bulbs and bulbils alkaloids extracts exhibited an antiradical effect with IC50 = 0.231±0.017 mg/mL and 0.233±0.093 mg/mL respectively, less than the effect of vitamin C with IC50 = 0.0194±0.0002 mg/mL. Antimicrobial activity results reveal that both alkaloid bulbs extracts at 50 mg/mL did not have any inhibitory effect against the studied strains using the disc diffusion method. According to this work, bulbs and bulbils alkaloid extracts show a moderate antioxidant effect; that could be recommended as a natural antioxidant. Although tuberose bulbs were used traditionally as a soap substitute; bulbs alkaloid extract has no antimicrobial effect. Keywords: Polianthes tuberosa L., bulbs, bulbils, alkaloids, antiradical activity, antimicrobial activity

Effect of Pilates Exercises on Cortisol Hormone and Blood Pressure Among Hypertensive Women

Background: Hypertension is a major risk factor for cardiovascular diseases such as stroke and coronary artery disease as well as causes mortality. The Pilates method is a conditioning program in hypertensive patients of the body and mind that is gaining in popularity and acceptance worldwide. Aim of Study: To determine the response of cortisol hormone level and blood pressure after Pilates exercise in hypertensive post-menopausal women. Methods: Sixty women participated in this study was selected from Belbies Central employees and outpatient clinic with age mean ± SD values in groups (A) and (B) were 52.83 ± 3.89 and 53.37 ± 3.66 years., respectively. All of them suffering from high blood pressure stage 2(systolic 140 or higher and diastolic 90 or higher), they took medications (beta blockers - vasodilator – diuretics) and postmenopausal form 1-5 years ago. The study design was pre-post study. Patients were assigned for 8weeks protocol into two groups: Group (A) received Pilates training exercises (bent knee, shoulder bridge, side kick front, side kick back, and single leg circle), while Group (B) received only anti-hypertensive medications. Group (A) performed 5 types of Pilates exercises per session for /3 sessions/ week/ 8 weeks. The outcome measures were blood pressure (systolic and diastolic), cortisol level, anticoagulant factors (prothrombin time (PT), partial prothrombin time (PTT)) and physical characteristic (weight, body mass index (BMI), and waist hip ratio) were evaluated at the baseline and the end of the study. Results: Pre- and post-treatment comparisons showed a statistically significant decrease of the measured variables in the group A (cortisol level 17.73%, systolic blood pressure 3.70%, Diastole blood pressure 5.01 %, partial prothrombin time 7.38%, where weight 2.92 %, Body mass index 2.98 %) and significant increase in prothrombin time 0.67 %. In group B cortisol level 10.48%, significant decrease in diastole blood pressure 1.73%, no significant increase in (prothrombin time 0.25%, Partial prothrombin time 0.28%, weight 0.64%, BMI 0.34%, waist hip ration 0.11%) as well as no significant decrease in systolic blood pressure 0.75

Multimodal "Sensory Illusions" for Improving Spatial Awareness in Virtual Environments

Inaccurate judgement of distances in virtual environments (VEs) restricts their usefulness for engineering development, in which engineers must have a good understanding of the spaces they are designing. Multimodal feedback can improve depth perception in VEs, but this has yet to be implemented and tested in engineering applications with systems which provide haptic feedback to the body. The project reported in this paper will develop a multimodal VE to improve engineers’ understanding of 3D spaces. It will test the concept of “sensory illusions” where the point of collision in the VE differs to the point of haptic feedback on the body. This will permit the use of fewer vibrotactile devices and therefore the development of a more wearable system. This paper describes related work in multisensory and tactile stimulation which suggests that our perception of a stimulus is not fixed to the point of contact
