Opis:
In this paper, we introduce new classes of nonsmooth second-order cone-convex functions and respective generalizations in terms of first and second-order directional derivative. These classes encapsulate several already existing classes of cone-convex functions and their weaker variants. Second-order KKT type sufficient optimality conditions and duality results for a nonsmooth vector optimization problem are proved using these functions. The results have been supported by examples.

Opis:
The present article proposes an estimator using the Item Sum Technique (IST) for the estimation of dynamic sensitive population mean using non-sensitive auxiliary information in the two-move successive sampling. Properties of the proposed IST estimator have been analysed. Possible allocation designs for allocating long-list and short-list samples pertaining to the IST have been elaborated. The comparison between various allocation designs has been carried out. Theoretical considerations have been integrated with numerical as well as simulation studies to show the working version of the proposed IST estimators in the two-move successive sampling.

Opis:
This paper addresses the problem of estimation of population mean of sensitive character using non-sensitive auxiliary variable at current wave in two wave successive sampling. A general class of estimator is proposed and studied under randomized and scrambled response model. Many existing estimators have been modified to work for sensitive population mean estimation. The modified estimators became the members of proposed general class of estimators. The detail properties of all the estimators have been discussed. Their behaviour under randomized and scrambled response techniques have been elaborated. Numerical illustrations including simulation have been accompanied to judge the performance of different estimators. Finally suitable recommendations are forwarded.

Opis:
Literary renditions of cities have always gravitated towards the spatial imagination and its ethical counterpart outside the textual space. This paper explores the multicultural geography of the North Indian city Allahabad (recently renamed Prayagraj) observed through Neelum Saran Gour’s postcolonial narratives Allahabad Aria and Invisible Ink, projecting the narrative alignment of spatial aesthetics and cultural ethics. Interrogating the spatial dimensions of a “narrative world” within narrative theory (Ryan) and its interdisciplinary crossover with cultural geography (Sauer; Mitchell; Anderson et al.), the article seeks to examine Gour’s literary city not simply as an objective homogeneous representation, but as a “kshetra” of spatio-cultural cosmos of lived traditions, memories, experiences and collective attitudes of its people, in the context of E. V. Ramakrishnan’s theoretical reflections. The article proposes new possibilities of adapting the Indian concept “kshetra” to spatial literary studies; its aim is also to suggest a new source of knowledge about the city of Allahabad through a community introspection of “doing culture” in the texts, bringing into view people’s shared experiences, beliefs, religious practices and traditions as offshoots of the postcolonial ethos. The article aims to re-contextualize the city’s longstanding multicultural ethics in the contemporary times of crisis, which may affect a shift in the city’s relevance: from regional concern to large-scale significance within ethnically diverse South Asian countries and beyond.

Opis:
The aim of the present numerical study was to analyse the pressure settlement behaviour and bearing capacity of asymmetric plus shaped footing resting on loose sand overlying dense sand at varying embedment depth. The numerical investigation was carried out using ABAQUS software. The effect of depth of embedment, friction angle of upper loose and lower dense sand layer and thickness of upper loose sand on the bearing capacity of the asymmetric plus shaped footing was studied in this investigation. Further, the comparison of the results of the bearing capacity was made between the asymmetric and symmetric plus shaped footing. The results reveal that with increase in depth of embedment, the dimensionless bearing capacity of the footings increased. The highest increase in the dimensionless bearing capacity was observed at embedment ratio of 1.5. The increase in the bearing capacity was 12.62 and 11.40 times with respect to the surface footings F1 and F2 corresponding to a thickness ratio of 1.5. The lowest increase in the dimensionless bearing capacity was observed at embedment ratio of 0.1 and the corresponding increase in the bearing capacity was 1.05 and 1.02 times with respect to the surface footing for footings F1 and F2 at a thickness ratio of 1.5.

Opis:
In the last few decades of the twenty-first century there was a great revival in consumer demand for linen, particularly in the form of apparel fashion products. This trend has continued into the first decade of the twenty-first century, and promotional activities to increase consumer awareness of the desirable characteristics of linen have intensified, especially in European countries. Linen is an expensive fabric when compared to the other fabric types like cotton, viscose, nylon, and polyester. Due to the complexity of the manufacturing process linen is considered a luxury fabric material. Linen is manufactured from the flax plant which is taking more time to source it as a raw material for fabric manufacturing. Therefore the cost of the linen fabric is higher and apparel prices are relatively higher in cost. Most of the consumers prefer the hand feel of the linen fabric and its comfortability factor. They also demand the elegant look of the linen fashion apparel too. Therefore even at a higher price, consumers in Sri Lanka are not reluctant to buy the linen fashion apparel. The climatic changes in Sri Lanka have also become a significant factor for choose linen fashion apparel. It brings a comfortability to the wearer in a hot climate. However, In Sri Lanka, linen is consumed by different groups of consumers who are highly demanding linen fashion apparel. But this demand is not normal. According to the demand and supply theories, when the price for a particular product rises, the demand for that particular product falls. However, when considering linen apparel, although the price is higher, demand does not fall. This study aims to find out factors that caused unusual demand for linen fashion apparel in Sri Lanka. Factors that influence consumer buying behavior will be discussed. Adopted quantitative and qualitative research methods used to gather, sort, and analyze data. The research is focused on female consumers and the age limit is denied in the research.

Opis:
Structural health monitoring of aircraft assures safety, integrity and reduces cost-related concerns by reducing the number of times maintenance is required. Under aerodynamic loading, aircraft is subjected to strain, in turn causing damage and breakdown. This paper presents a review of experimental works, which focuses on monitoring strain of various parts of aircraft using optical fibre sensors. In addition, this paper presents a discussion and review on different types of optical fibre sensors used for structural health monitoring (SHM) of aircraft. However, the focus of this paper is on fibre bragg gratings (FBGs) for strain monitoring. Here, FBGs are discussed in detail because they have proved to be most viable and assuring technology in this field. In most cases of strain monitoring, load conditioning and management employs finite element method (FEM). However, more effort is still required in finding the accurate positions in real time where the sensors can be placed in the structure and responds under complex deformation.

The patient should be monitored by caregivers. Caregivers can’t predict the accurate timing and the exact change of the optimal result of the patient. In this case, we have to use sensor to monitor the patient activities without manual support. By using eye blink sensor, motion sensor and temperature sensor to check the level of patient and it will be displayed in LCD. If some abnormalities occur, we have to give alarm by using buzzer to caregiver, doctor or family members. We have to use ZigBee, for storing the patient details in the hospital management. It is useful to check the patient report with secure level in the database.

Since ancient times textiles have become a rich cultural heritage. Textile designs convey a rich textile tradition in Sri Lanka in the maritime region mural paintings which are significant in their stylistic, elegant and complex nature. This iconic representation of Sri Lankan art produced an elaborate textile tradition that blended with an important visual, cultural expression and a distinctive craftsmanship. These design motifs are different compared to the other temple mural tradition in Sri Lanka showing originality and response to a well formed social economic structure. It is, in terms of textile design, aesthetic of artistic value, visually intense, as a priority and has a wide range of design placement types. The objective of the study is to identify the textile design patterns and its unique design formats depicted in the Southern school of art with a view to identifying it’s an iconic features. The present study adopted the qualitative research method and data were gathered from the three selected temples in the Southern province and one temple from the Western province; Purvaramaya at Kataluwa, Sunandaramaya at Ambalangoda, Thotagamuwa temple at Telwatta, Sri Subadhraramaya Balapitiya and Subodharamaya at Karagampitiya, Colombo (Western province) This study reveals the sophistication of textile design composition, its characteristics and the rising demand for such flora and fauna for print designs.

Opis:
The study examined the relationships among some demographic factors, self-compassion and interdependent happiness of the married Hindu couples. Using a correlational research design, 600 participants (300 couples) were chosen by a snowball sampling. Self-compassion Scale (Neff, 2003b), Socioeconomic Status Scale (Aggarwal et al., 2005) and Interdependent Happiness Scale (Hitokoto & Uchida, 2015) were used to collect data. Findings revealed that some demographic factors such as age, years of marriage and number of family members were positively correlated with self-compassion while the number of children and socioeconomic status were negatively correlated with it. Age, years of marriage and the number of children had a positive relationship with interdependent happiness. Self-compassion evinced a significant positive correlation with the interdependent happiness of the couples. The nature of family and self-compassion accounted for significant variance in the scores of interdependent happiness of the couples. The study constitutes one of the limited studies which assessed the relationships among a set of demographic factors, self-compassion and interdependent happiness on a sample drawn from a collectivistic society. The results have been discussed in the light of extant theoretical and empirical findings of self-compassion and interdependent happiness. The findings may have significant implications for understanding positive life outcomes of people with self-compassion belonging to a collectivistic culture. The theory, practise and policy implications of the findings have been discussed. Directions for future research have also been provided along with some limitations of the study.

Opis:
analysis is carried out to study chemically reactive, viscous dissipative effects of an incompressible and electrically conducting fluid with MHD free convection adjacent to a vertical surface with variable thermal conductivity (VTD) and variable mass diffusivity (VMD). An approximate numerical solution for the steady laminar boundary layer flow over a wall of the surface in the presence of species concentration and thermal mass diffusion has been studied. Using numerical techniques the governing boundary layer equations are solved to get the exact solution. Numerical calculations are carried out for different values of dimensionless parameters. The results are exhibited through various graphs and it is observed from the analysis of the results that the velocity field is appreciably influenced by the magnetic effect, porous effect, chemical reaction and buoyancy ratio between the species and thermal diffusion at the wall of the surface.
