 Abstract

The usability and the user interface of a publisher website is an important component to determine the performance and functioning. For the past two decades, right after introducing of heuristic evaluation principles by Nielsen (1990), it has been implemented to measure the usability of various kinds of websites. The user interfaces and usability of book publisher was the subject of some research studies and many evaluation techniques have developed to assess publisher's websites user interfaces. This study is to evaluate the user interface of the top ten book publishers' websites which are based on the rankling by the "Publishers Weekly", a weekly news magazine focused on the international book publishing business by applying the ten heuristics evaluation principles (Nielsen 1990). The study engages a quantitative and qualitative based survey approaches, and seeks to gather the perception and experiences of Pondicherry University students of post-graduate and PhD students about the book publishers' websites. The results of the study shows that users liked the publishers' websites user interface as most of them were attractive due to pleasant layout, the use of simple language consistently throughout the system and the use of standards in all areas across the WebPages. The main weaknesses of the publishers websites as per the experience and perception of the respondents were lack of adequate and appropriate feedback, inadequate users control features, limited online help, slow loading due to some websites used heavy graphics and multimedia contents.

 Abstract

Ability to produce large metallic parts with low to medium complexity made wire arc additive manufacturing (WAAM) a viable alternative to the conventional manufacturing processes. Prediction and optimization of process parameters is of the paramount importance due to influence of those on the build quality and mechanical properties. In this article, WAAM manufacturing process of SS304L was investigated for the prediction and optimization of 304L stainless steel. In order to investigate the influence of voltage, current and travel speed, a L16 Taguchi experimental design was used with the geometrical characteristics of the deposit and the hardness as the response variables. The TOPSIS (Techniques for Order - Preferences by Similarity to - Ideal Solution) technique was used to determine the ideal process parameters. The data obtained indicate that travel speed has the greatest impact on WWB and HWB, while heat input has an impact on microhardness. The optimal process parameters, V= 21.5 V, I= 80 A, TS= 200 m/min, were obtained.

 Abstract

Migrant workers come under the unorganised sector in India which covers the agriculture, domestic, and construction sector ect.. Hence Social security plays a vital role in ensuring the protection of workers. This paper enlighten the plight of migrant women workers the workers faced many problems in day to day life Along with during the covid-19 period and also a glance on social security scheme which are presently available for the migrant workers. The objective paper is to know the social security for migrant workers and to understand the plights of migrant women workers. The Researcher is used the secondary data method and the data collected from government web sites, international labor organization and websites related to the migration workers. The study found that several government schemes available for migrant workers only few of them aware about it and poverty is main cause for migration.

 Abstract

Air breathing engines are widely used in aircraft and missile applications. These air breathing engines will work efficiently in supersonic and hypersonic conditions only. Supersonic air breathing engines work in the range of mach 3 to 5 and hypersonic air breathing engines work on above mach 5 or 6. The hypersonic air breathing engines are known as scramjet engines. Air breathing engines efficiency was increased by increasing the pressure recovery or pressure at the outlet of the inlet. Thus with the increasing efficiency of hypersonic inlet diffusers , it directly improves the efficiency of the hypersonic air breathing engine. In this paper numerical analysis was conducted to improve the efficiency of hypersonic inlet diffusers by varying cowl and ramp geometry (i.e angle and lengths ). It is observed that with the increase of lengths of ramp outlet mach number and pressure are increased.

 Abstract

Cloud storage as one of the most important services of cloud computing helps cloud users break the bottleneck of restricted resources and expand their storage without upgrading their devices. In order to guarantee the security and privacy of cloud users, data are always outsourced in an encrypted form. However, encrypted data could incur much waste of cloud storage and complicate data sharing among authorized users. We are still facing challenges on encrypted data storage and management with deduplication. Traditional deduplication schemes always focus on specific application scenarios, in which the deduplication is completely controlled by either data owners or cloud servers. They cannot flexibly satisfy various demands of data owners according to the level of data sensitivity. In this paper, we propose a heterogeneous data storage management scheme, which flexibly offers both deduplication management and access control at the same time across multiple Cloud Service Providers (CSPs). We evaluate its performance with security analysis, comparison and implementation. The results show its security, effectiveness and efficiency towards potential practical usage.

 Abstract

Dalit literature is one of the important fields developing in the Indian Writing in English. Dalit literature is a literature which studies the life journey of people who belongs to marginalized community. It includes the sufferings and pain undergone by a dalit or untouchable among other higher ranking people in the society. The main objectives of the article are to explore the themes and ideas proposed in Indian dalit literature, to study the pain and sufferings of dalit community through Karna, to evaluate the status of dalits in the contemporary India, to portray the prevailing caste and class discrimination in the society and to envision people about the sudden need for bringing equality in the society. The research article navigates the unsung hero of Mahabharata Karna in the light of the dalit context as he faced the issues of caste discrimination throughout his life. It also explains that how the Karna's life is perfectly blended with the lives of the dalit people in the Indian society through certain issues. The article statement enlightens that a dalit individual has the right and liberty to have education and identity of their own despite the caste differences and it questions the concept of equality when several people are not treated as such.
