Authors: SWAIN RANJITA KUMARI , PANTHI VIKAS , BEHERA PRAFULLA KUMAR
Published: January 2021

As Unified Modeling Language (UML) activity diagrams capture the key system behavior, the UML activity diagram is well suited for the system level testing of systems. In this paper, first an activity flow graph is derived from activity diagram. Then, all the required information is extracted from the activity flow graph (AFG). The activity flow graph (AFG) for the activity diagram is created by traversing the activity diagram from beginning to end, showing choices, conditions, concurrent executions, loop statements. From the graph different control flow sequence are identified by traversing the AFG by depth first traversal technique. Next, an algorithm is proposed to generate all activity paths. Finally, test cases are generated using activity path coverage criteria. Here, a case study on Soft drink Vending Machine (SVM) has been presented to illustrate our approach.

Published: January 2021

Generally, complexity of Software affects the development and maintenance Cost. The Complexity of the software increases, when the number of Components increase, among these components, some are more critical than others which will lead to catastrophic effects on field use. Hence, it is needed to identify such critical components after coding to test them rigorously. In this paper, we presented a novel approach that helps to identify the critical components in the software based on Criticality Analysis. Criticality Analysis analyzes the critical value of each component based on their Sensitivity and Severity metrics.

Authors: MAHALI PRATEEVA , ACHARYA ARUP ABHINNA
Published: January 2021

With the exponential growth in size and complexity of softwares, the testing activity is no more limited to testing phase of SDLC (Software Development Life Cycle). Testing process has been made iterative and incremental in Object Oriented development scenario. This leads to increase in effort and time required for testing as well as explosion in test case. But when it comes to regression testing, it has the additional issue of test case retesting which further increasing the effort and time. So a suitable prioritization technique should be used to address these issues. In this paper we had given a proposal which is based on prioritization of test cases using GA (Genetic Algorithm). This process is found to be very effective during regression testing. In this paper we found an optimized independent path having maximum critical path value, which further leads to prioritization of test cases. The three component of regression testing i.e effort, time, cost will be gradually reduce by using this approach.
INCREASING ACCURACY OF K-NEAREST NEIGHBOR CLASSIFIER FOR TEXT CLASSIFICATION
Authors: PATEL FALGUNI N. , SONI NEHA R.
Published: January 2021

k - Nearest Neighbor Rule is a well-known technique for text classification. The reason behind this is its simplicity, effectiveness, easily modifiable. In this paper, we briefly discuss text classification, k-NN algorithm and analyse the sensitivity problem of k value. To overcome this problem, we introduced inverse cosine distance weighted voting function for text classification. Therefore, Accuracy of text classification is increased even if any large value for k is chosen, as compared to simple k Nearest Neighbor classifier. The proposed weighted function is proved as more effective when any application has large text dataset with some dominating categories, using experimental results.

Authors: Athavale Rohit , N Tejas , Jayashree HV
Published: January 2021

A Multi-UART controller is presented in this paper which will serve the purpose of communication between different systems or sub-systems of large system. The different systems or sub-systems of a large system will be able to operate at different baud rates and will use the UART (Universal Asynchronous Receiver Transmitter) to perform communication. This controller has different modes of operation—Normal, Bridge and Hub modes. The controller uses an asynchronous FIFO (First In First Out) block for communication purpose. This controller will reduce the synchronization errors between different systems or sub-systems which are communicating with each other. Since communication between sub-systems or different systems is handled by this controller it
will not burden the master processor or main system with communication related operations. This paper improves over [2] as the modes of operation being incorporated in the design itself and are completely reconfigurable.

Analysis of Distortion Parameters of Eight node Serendipity Element on the Elements Performance
Authors: Jagota Vishal , Sethi A. P. S.
Published: January 2021

Often the result produced using FEM technique on the distorted shaped element gives poor result. Moreover if the results are poor then the design will fail. Eight noded serendipity elements is the most widely used element in 2-D analysis of structures. But despite its benefits it remains distortion sensitive. In the majority of computer programs, automatic mess generation is an integral part of the program. For complex shapes, the automatic grid generation will result in distorted quadrilateral shapes. Thus the solution obtained by using these meshes will produce erroneous results so it becomes necessary to incorporate the distortion measures in to these automatic mesh generations to limit the errors. Here in this paper distortion parameters are defined in terms of the coefficient of the element’s shape polynomials and are tested for a range of distortion.

Published: January 2021

The thermal conductivity of heating or cooling fluids is a very important property in the development of energy efficient heat transfer systems, which is one of the important needs of many industries. However, low thermal conductivity is a primary limitation in developing energy-efficient heat transfer fluids that are required for cooling purposes. Nanofluids are nanotechnology-based heat transfer fluids that are engineered by stably dispersing nanometer-sized (below 100nm) solid particles (such as ceramics, metals, alloys, semiconductors, nanotubes, and composite particles) in conventional heat transfer fluids (such as water, oil, diesel, ethylene glycol and mixtures) at relatively low particle volume concentrations. These suspended nanoparticles can change the transport and thermal properties of the base fluid. Adding to ethylene glycol, it has been observed that an enhancement of nearly 36 % with al2o3 nanoparticles and 40% enhancement with copper nanoparticles in the thermal conductivity. This paper focuses on some of the automotive applications such as coolant for automobiles, showcases a few of them that are believed to have the highest probability of success in this highly competitive industry and to raise the awareness on the promise of nanotechnology, its potential impact on the future of the automotive industry.

Gender-wise Analysis of Children’s Influence across Stages of Family Decision Making Process
Authors: Nain Harikishni
Published: January 2021

Past studies have considered gender of children as an important variable (Lee and Collins, 2000) in explaining the influence of child on family decision making. The findings from prior research suggest that in family purchases, female children (probably due to the early learning of sex roles) have more influence than male children (Lee and Collins, 2000; Moschis and Mitchell, 1986). This study provides a gender-wise analysis of children’s influence across stages of family decision making process in the purchase of child product and family product in Indian families. A cross-sectional survey method was carried out and the primary data for the study was collected through a “structured non-disguised” questionnaire. The sample population consisted of 488 male children and 278 female childrenin the age group 13 to 18 years.The collected data have been analyzed and interpreted with the help of statistical tools such as mean, standard deviation and repeated measures ANOVA. It was posited that children’s influence in stages of decision making process for child product and family product varies across (i) gender of children (H1), (ii) place of residence, i.e., rural and urban families (H2). Both the hypotheses were not supported by the analysis results.
Мифопоэтический Образ «Пороговой» Личности в Русской и Азербайджанской Реалистической Прозе Рубежа XX-XXI Веков
Authors: ALIYEVA Tamılla
Published: January 2021

В статье рассмотрены общие типологические особенности мифопоэтического направления азербайджанской и русской реалистической прозы рубежа XX-XXI веков. Затронуты исторический контекст и основные тенденции развития мифотворчества в творчестве русских и азербайджанских писателей, предпосылки формирования и поэтическое своеобразие условно-метафорической прозы соответствующего периода. Отдельно изучен мотив переходности и образ «пороговой» личности в произведениях известных писателей. Обозначены направления дальнейших исследований этой актуальной научной проблемы. Отмечается, что в конце XX-XXI веков в азербайджанской и русской литературе, в культуре наблюдается интереса к мифу, к специфике мифологического мировосприятия, что было связано с кризисом тоталитарного советского общественного строя, господствующей ортодоксальной идеологии и методологии социалистического реализма. Рассматривается роль мифопоэтического мировосприятия в процессе кардинального обновления и глубинной трансформации поэтической системы реалистической прозы в последней трети ХХ – начала XXI веков. С этой точки зрения основное внимание уделяется архетипическому мотиву переходности и мифопоэтическому образы «пороговых» (лиминальных) персонажей, актуальность которых в современном литературном мифотворчестве была обусловлена особенностями эпохи, переходного периода истории. Широкое распространение на рубеже веков мотива переходности и пороговых персонажей в азербайджанской и русской прозе и в целом в художественной литературе бывших советских народов было обусловлено именно переломным характером соответствующей эпохи советской истории, которая началась с начала 60-х годов прошлого столетия. В статье рассмотрены генетические корни и обусловленность «пороговых» персонажей И. Шихлы, В. Шукшина, В. Белова, Анара, Ю. Самедоглу, П. Проскурина, Л. Улицкой внешними обстоятельствами, переломным характером эпохи. Показывается, что эти двойственные личности оторвались от своего привычного берега, но как персонажи-максималисты не готовы к принятию иных ценностей, примкнуть к другому сообществу. С этой точки зрения проанализированы соответствующие качества таких амбивалентных героев азербайджанской и русской прозы, как Симург (М. Ибрагимбеков «И не было лучше брата»), Ахмед-ветрогон (М. Сулейманлы «Ахмед-ветрогон становится беком»), Иван Африканович (В. Белов «Привычное дело»), Роберт Викторович (Л. Улицкая «Сонечка»), Керванбашы, Гаджи Мир Гасан ага Сейях (К.

PEDAGOGIA FREIRIANA E PEDAGOGIAS FEMINISTAS: (DES)ENCONTROS E DIÁLOGOS (IM)POSSÍVEIS?
Authors: Macedo Eunice
Published: January 2021

Este artigo propõe cruzamentos e diálogos entre a pedagogia freiriana e as pedagogias feministas, como tradições teóricas e metodológicas emancipatórias da voz. A discussão assenta na proposta filosófica política de educação de Freire e de teóricas feministas como bell hooks e Iris Young, Marijke de Koning, e mesmo Kathleen Weiler, com maior ou menor proximidade à ideação freiriana. Começo por auscultar possibilidades de diálogo entre estas tradições. Passo a situar a educação libertadora como política localizada que vai além do tempo e do lugar para, no ponto seguinte, provocar o encontro entre a ideação freiriana e feminista. Por último, discutem-se princípios das pedagogias feministas como corporização e enraizamento do movimento feminista, que permitem identificar pegadas de Freire.

Avaliam-se os contextos de partida, o interessante mosaico de circunstancias internacionais e nacionais em que se moveram tais relações, as raízes das lutas emancipatórias caribenhas, latinoamericanas e mundiais da épica, e o impacto do protagonismo histórico de Freire e da Revolução Cubana, suas identidades, paralelos e confluências.
PAULO FREIRE NA ÁFRICA CONTRIBUIÇÃO POLÍTICO-PEDAGÓGICO NA FORMAÇÃO DE EDUCADORES DE ADULTOS EM CABO VERDE
Authors: Varela Florenço Mendes
Published: January 2021

No quandro da celebração do Centenário de Paulo Freire, pretendo, com este artigo, partilhar a contribuição político-pedagógico de Paulo Freire na formação de educadores em Cabo Verde e suas repercussões nas políticas educativas, tendo como base a minha tese de Doutorado em Educação (Varela, 2018). País arquipelágico, africano e saheliano, Cabo Verde é um dos raros países que desenvolveu uma política de educação e formação de adultos, original, com uma continuidade notável, um subsistema de educação extraescolar, paralelo e equivalente ao subsistema escolar, com um currículo e um programa específico, uma carreira de educadores integrada na carreira do pessoal docente e um sistema de reconhecimento e certificação. O realizado que conduziu à tese, propõe-se a contextualizar historicamente a formação de educadores e analisar os seus resultados, utilizando o estudo de caso, com caráter essencialmente descritivo. No que respeita à contribuição político-pedagógico de Paulo Freire, os resultados apontam que a formação de educadores teve repercussões positivas, nomeadamente, no desenvolvimento de conhecimentos para o exercício da profissão, na democratização do acesso à educação, na valorização da carreira profissional do Educador de Adultos e no fortalecimento do sistema educativo nacional.

This paper uses panel data to examine the impact of ownership structure index on the financial performance of 73 listed companies of the Indian national stock exchange from 2009 to 2016. To measure the Panel Regression in this study, the FEM model was used. The different dimensions of the ownership structure index involve ten items used as the Independent variable of this study. Two measures have been adopted to estimate the firm performance that is; ROA and ROE. In contrast, the control variables are firm size and leverage. This study's empirical evidence shows that the ownership structure index has significant impact on a firm's performance measured by ROA and ROE of Indian Nifty 100 listed companies. Findings of this study support previous empirical studies performed and add some value in the research area of finance that explores different aspects of the board of directors' index and ownership structure index in Indian market by using Nifty 100 as an example.
Humor styles and the ten personality dimensions from the Supernumerary Personality Inventory
Authors: Kfrerer Marisa , Schermer Julie
Published: January 2021

Background

The present study examines the relationship between humor styles and the 10 Supernumerary Personality Invento-ry (SPI) traits to understand how humor styles correlate with personality dimensions “beyond the Big Five” model. Humor styles and the personality dimensions of the SPI have yet to be explored. Therefore, the aim of this study is to explore how humor styles correlate with traits outside of conventional personality models, in order to better un-derstand humor expression related to personality traits.

Participants and procedure

The data were from 693 adult participants (135 men and 560 women) from North America.

Results

All four humor styles positively correlated with the SPI humorousness scale. The two positive humor styles, affiliative and self-enhancing, had significant positive correlations with the egotism SPI scale. The two negative humor styles, aggressive and self-defeating, had significant positive correlations with the SPI scales of seductiveness and manipu-lativeness and significant negative correlations with the integrity scale from the SPI. A sub-group of the sample (n = 471) also completed a Big Five personality measure. For this sample, the variance due to the Big Five was re-gressed out of the SPI scales.

Conclusions

The correlations between the SPI residuals and the humor style scores decreased from the unaltered SPI scale scores except for the aggressive humor style correlations, which were less affected, suggesting that this dimension of humor may have some variance “beyond” the Big Five.

Introduction

Emphysema and chronic obstructive lung disease were previously identified as major risk factors for severe disease progression in COVID-19. Computed tomography (CT)-based lung-density analysis offers a fast, reliable, and quantitative assessment of lung density. Therefore, we aimed to assess the benefit of CT-based lung density measurements to predict possible severe disease progression in COVID-19.

Material and methods

Thirty COVID-19-positive patients were included in this retrospective study. Lung density was quantified based on routinely acquired chest CTs. Presence of COVID-19 was confirmed by reverse transcription polymerase chain reaction (RT-PCR). Wilcoxon test was used to compare two groups of patients. A multivariate regression analysis, adjusted for age and sex, was employed to model the relative increase of risk for severe disease, depending on the measured densities.

Results

Intensive care unit (ICU) patients or patients requiring mechanical ventilation showed a lower proportion of medium- and low-density lung volume compared to patients on the normal ward, but a significantly larger volume of high-density lung volume (12.26 dl IQR 4.65 dl vs. 7.51 dl vs. IQR 5.39 dl, p = 0.039). In multivariate regression analysis, high-density lung volume was identified as a significant predictor of severe disease.

Conclusions

The amount of high-density lung tissue showed a significant association with severe COVID-19, with odds ratios of 1.42 (95% CI: 1.09-2.00) and 1.37 (95% CI: 1.03-2.11) for requiring intensive care and mechanical ventilation, respectively. Acknowledging our small sample size as an important limitation; our study might thus suggest that high-density lung tissue could serve as a possible predictor of severe COVID-19.

Published: January 2021

The present paper deals with food analysis and feeding behavior of the snow trout Schizothorax richardsonii (Gray) which is a cold water herbivore fish by nature. It is locally called Asela and is distributed in Himalayan and sub-Himalayan regions of Asia and has considerably attracted the attention of researchers due to its high productivity. The health and growth of fishes is greatly influenced by their nutrition and feeding. It has been observed in the present study that the adult fish naturally feeds on diatoms and algae. An experiment was conducted on artificial feeding of fish by giving three different types of food, i.e., formulated diet as control, periphton based diet and a mixture of both in different artificial raceways. It was observed that the fish conversion ratio (FCR) of the fish pooled in the raceway one (R1), i.e., feeding with formulated was high (6.85) due to balanced nutrients. It is recommended that with the introduction of balance artificial diet may be helpful in increasing the production of S. richardsonii.
DIVERSITY OF PREDACEOUS COCCINELLID BEETLES (COLEOPTERA: COCCINELLIDAE) IN UTTARAKHAND, NORTH INDIA
Authors: Pervez Ahmad , Yadav Meena , Khan Moina
Published: January 2021

A field survey was conducted to explore the diversity of predaceous ladybird beetles (Coleoptera: Coccinellidae) by sampling adults and larvae from five geographical habitats of Uttarakhand, North India. As a result, eighteen predaceous ladybird beetle species were identified belonging to 15 genera and 3 subfamilies: Chilocorinae, Coccinellinae, and Scymninae. These species were: Platynaspis saundersi, Adalia hexaspilota, Alloneda dodecaspilota, Calvia albida, Menochilus sexmaculatus, Coccinella septempunctata, Coccinella transversalis, Harmonia eucharis, Harmonia sedecimnotata; Hippodamia variegata, Illeis cincta, Illeis confusa, Micraspis discolor, Oenopia sauzeti, Propylea dissecta; Propylea luteopustulata; Palaeoneda auriculata and
Scymnus posticalis. Of these, six species ladybird beetles are the first time reported from Uttarakhand. Their distinctive characters, distribution, host plant-prey range, active period, and ecological importance have been described. A few of these species may be potentially utilized as biological agents to control many phytophagous
insect pests of agriculture and horticulture crops. A disparity was observed in the ladybird-abundance, as both the number of individuals of ladybirds and their frequency in the population differed significantly. The dominance of a few ladybird beetles, particularly C. septempunctata, M. sexmaculatus, C. transversalis and H. variegata was
confirmed by the low value of Simpson’s Dominance Index (0.1903) further indicating the disparity in the populations of different ladybird species in a community
