Cognitive Based Context Aware Reference History Management Tool
Dharani Punithan(다라니),Bob McKay(로버트이안맥케이) 한국HCI학회 2009 한국HCI학회 학술대회 Vol.2009 No.2
The aim of the research is to focus on the cognitive principles and to achieve human-level intelligence in referring context based browser history and the Windows history. One of the major problems faced by today's computer users is insufficient and single exclusive context based reference of the browser history and the Windows history. Today we search for the browser history and Windows history in different places even though the context is the same. For e.g., When working on a research paper or preparing a business presentation, a user may require to refer many web sites on the internet and various documents on the local computer. The browser can provide only time based history. The windows document history is also time based and limited to list only few documents. Hence, we propose a tool "Cognitive Based Context Aware Reference History Management Tool" which helps to access the exclusive reference of context and time based history in one place. The tool also proposes to store image history with urls and classifies images of a specific topic accessed in different time, bookmarks management and cross browser history management. These features are very useful as we can access all related documents (doc, docx, ppt, pptx, pdf, txt, and html), web pages, images and bookmarks in one place. The tool uses the cognitive principles like classification and association to achieve the purpose.

<P>The intention of this paper is to explore the problem of pinning sampled-data synchronization of coupled reaction-diffusion neural networks with added inertia and time-varying delays. Through the proper variable substitution, the original system is transferred into first-order differential equations. Then, by constructing a suitable Lyapunov-ICrasovsidi functional (LKF), which uses more information of the delay bounds, global asymptotic synchronization criteria for the considered system are established in the form of LMIs. The acquired LMIs can be simply examined for their practicability by utilizing any of the accessible softwares. At last, two examples are furnished to manifest the efficacy of the derived criteria.</P>
High efficiency electrospun TiO2nanofiber based hybrid organic-inorganic perovskite solar cell
Dharani, Sabba,Mulmudi, Hemant Kumar,Yantara, Natalia,Thu Trang, Pham Thi,Park, Nam Gyu,Graetzel, Michael,Mhaisalkar, Subodh,Mathews, Nripan,Boix, Pablo P. The Royal Society of Chemistry 2014 Nanoscale Vol.6 No.3
The good electrical and morphological characteristics of TiO2 nanofibers and the high extinction coefficient of CH3NH3PbI3 perovskite are combined to obtain a solar cell with a power conversion efficiency of 9.8%. The increase of the film thickness dramatically diminishes the performance due to the reduction in porosity of the TiO2 nanofiber framework. The optimum device (similar to 413 nm film thickness) is compared to a planar device, where the latter produces higher V-oc but lower J(sc), and consequently lower efficiency at all measured light intensities.

The article provides information on ceramic / nanostructured materials which are suitable for solid oxide fuel cells (SOFCs) working between 500 to 1000℃. However, low temperature solid oxide fuel cells LTSOFCs working at less than 600℃ are being developed now-a-days with suitable new materials and are globally explored as the "future energy conversion devices". The LTSOFCs device has emerged as a novel technology especially for stationary power generation, portable and transportation applications. Operating SOFC at low temperature (i.e. < 600℃) with higher efficiency is a bigger challenge for the scientific community since in low temperature regions, the efficiency might be less and the components might have exhibited lower catalytic activity which may result in poor cell performance. Employing new and novel nanoscale ceramic materials and composites may improve the SOFC performance at low temperature ranges is most focused now-a-days. This review article focuses on the overview of various ceramic and nanostructured materials and components applicable for SOFC devices reported by different researchers across the globe. More importance is given for the nanostructured materials and components developed for LTSOFC technology so far.

In a Gas Insulated Substation (GIS), Very Fast Transients (VFTs) are generated mainly due to switching operations. These transients may cause internal faults, i.e., layer-to-layer faults in a capacitively graded bushing as it is one of the most important terminal equipment for GIS. The healthiness of the bushing is generally verified by measuring its leakage current. However, the change in current magnitude/pattern is only marginal for different types of fault conditions. Leakage current monitoring (LCM) systems generate large amounts of data and computer aided interpretation of defects may be of great assistance when analyzing this data. In view of the above, ANN techniques have been used in this study for identification of these minor faults. A single layer perceptron network, a two layer feed-forward back propagation network and cascade correlation (CC) network models are used to identify interlayer faults in the bushing. The effectiveness of the CC network over perceptron and back propagation networks in identification of a fault has been analysed as part of the paper.
Modeling interply debonding in laminated architectural glass subject to low velocity impact
Flocker, F.W.,Dharani, L.R. Techno-Press 1998 Structural Engineering and Mechanics, An Int'l Jou Vol.6 No.5
Standard finite element wave propagation codes are useful for determining stresses caused by the impact of one body with another; however, their applicability to a laminated system such as architectural laminated glass is limited because the important interlayer delamination process caused by impact loading is difficult to model. This paper presents a method that allows traditional wave propagation codes to model the interlayer debonding of laminated architectural glass subject to low velocity, small missile impact such as that which occurs in severe windstorms. The method can be extended to any multilayered medium with adhesive bonding between the layers. Computational results of concern to architectural glazing designers are presented.

Purpose: Authors of scholarly writing are underrepresented in discussions about improving the academic publishing system. The objective of this study was to assess the possibility of harmonizing manuscript preparation and the submission guidelines of journals by assessing the opinions of dental faculty members who worked in the state of Andhra Pradesh, India. Methods: A cross-sectional survey of 1,286 participants from 16 dental schools in Andhra Pradesh was conducted from March 15, 2021 to April 15, 2021. The questionnaire addressed the participants’ demographic details and perspectives on the guidelines for manuscript preparation and the need to harmonize those guidelines with the publication process. The online questionnaire was generated using Google Forms and consisted of six dichotomous, one multiple-choice, and seven Likert scale items. Descriptive statistics were obtained. Results: Of the 894 (69.5%) dental faculty members who responded, 448 (50.1%) were not aware of the International Committee of Medical Journal Editors’ guidelines for manuscript preparation and submission. During the manuscript revision process, 792 (95.5%) had experienced difficulty with the variation in author guidelines for each journal, especially the guidelines for formatting tables, reference style, and citation of references in-text. The idea of a standardized template for manuscript preparation and submission was supported by 800 respondents (86.7%). Conclusion: Dental faculty members in India experienced difficulty in manuscript preparation for medical journals due to the differing editorial policies among journals. Therefore, a standardized template providing uniformity in style and format is needed.
