Assessment of Articular Cartilage by Second Harmonic Microscopy: Challenges and Opportunities
Get PDFSecond harmonic microscopy (SHM) has emerged as a powerful non-destructive optical imaging modality that has high potential to perform the advanced structural characterization of intact articular cartilage. This article provides the current status, opportunities, and challenges of SHM for the use in cartilage evaluation. A novel perspective on SHM is being addressed that includes the reason, need and the importance of SHM in the assessment of articular cartilage. By taking the advantage of collagen specificity and high-resolution imaging, SHM can detect the structural and morphological changes in early stage cartilage damage that would otherwise be overlooked by standard clinical imaging methods such as radiography and arthroscopy. The current status of SHM for articular cartilage analysis and the major progress reported in recent literature are briefly described herein. We summarize the status of scientific efforts and the challenges that need to overcome before moving toward clinical applications of SHM in the context of cartilage evaluation.publishedVersionCopyright © 2019 Kumar and Kumar.

Article and Author Level Measurements
Get PDFArticle and author level measurements have been discussed in this Unit. Author and researcher identifiers are absolutely essential for searching databases in the WWW because a name like D Singh can harbour a number of names such as Dan Singh, Dhan Singh, Dhyan Singh, Darbara Singh, Daulat Singh, Durlabh Singh and more. The ResearcherID.com, launched by Thomson Reuters, is a web-based global registry of authors and researchers that individualises each and every name. Open Researcher and Contributor ID (ORCID) is also a registry that uniquely identifies an author or researcher. Both have been discussed in this Unit. Article Level Metrics (Altmetrics) has been treated in this Unit with the discussion as to how altmetrics can be measured with Altmetric.com and ImpactStory.org. Altmetrics for Online Journals has also been touched. There are a number of academic social networks of which ResearchGate.net, Academia.edu, GetCited.org, etc. have been discussed. Regional journal networks with bibliometric indicators are also in existence. Two networks of this type such as SciELO – Scientific Electronic Library Online, and Redalyc have been dealt with. This Unit discusses in details aspects such as Unique Identifiers for Authors and Researchers; Article Level Metrics (Altmetrics); Academic Social Networks; and Regional Journal Networks with Bibliometric Indicators
Fairness-Based User Scheduling and Performance Optimization in Energy Harvesting Cognitive Network
No full textIn this work we consider a cognitive radio network with a energy harvesting relay that facilitates coexistence between primary users and multiple secondary users (SU) and a secondary destination. We analyze the outage performance of this cognitive radio network that employs a decode-and-forward (DF) relay and harvests energy from the secondary user’s transmitted signal. Cumulative distribution function-based user scheduling is performed for equitable allocation of channels to each SU. We consider block Rayleigh fading channels and derive novel closed-form expressions for the outage probability and system throughput. Monte Carlo simulations are conducted to verify the accuracy of the outage expression. We also develop the expression for the outage probability at a high interference threshold and utilize it to examine the impact of the power splitting factor (α) on overall performance. Our results demonstrate that through using an optimum power splitting factor the outage performance can be enhanced by nearly 2 dB
Power Forecasting in Photovoltaic System using Hybrid ANN and Wavelet Transform based Method
No full text63-74Solar energy is a sustainable, renewable energy which is a part of latest industry standards of operation in line with
industry 4.0. Solar power variability leads to fluctuation and uncertainty in Photovoltaic (PV) output power. It is a
significant issue with regard to the high penetration of PV power generation. The solar irradiance is affected by weather
conditions, and varies with geographical locations. Accurate PV power output forecasting is essential for the planning and
scheduling alternate sources of conventional power. In this paper we propose a frequency domain approach for forecasting
of short-term PV output power. The wavelet transform allows identification of periodic components with time localization,
whereas the Artificial Neural Network (ANN) technique allows us to model the non-linearities in the PV time series. In this
paper, PV power data for the city Bareilly, Uttar Pradesh is forecasted. Numerical simulations show that the proposed
forecasting method for PV power output, shows a significant increase in accuracy over other similar methods. The root
Mean Square Error, Mean Absolute Error for the proposed method are also calculated and compared with state-of-the art
methods for PV power forecasting

Research Evaluation Metrics
Get PDFThis module dwells on a number of methods (including old and new) available for research evaluation. The module comprises the following four units:
Unit 1. Introduction to Research Evaluation Metrics and Related Indicators.
Unit 2. Innovations in Measuring Science and Scholarship: Analytical Tools and Indicators in Evaluation Scholarship Communications.
Unit 3. Article and Author Level Measurements, and
Unit 4. Online Citation and Reference Management Tools.
Brief overviews of the units are presented below.
Unit 1 encompassed and discussed citation analysis, use of citation-based indicators for research evaluation, common bibliometric indicators, classical bibliometric laws, author level indicators using authors' public profiles, article level metrics using altmetric tools. It is to be noted that author level indicators and article level metrics are new tools for research evaluation. Author level indicators encompasses h index, citations count, i10 index, g index, articles with citation, average citations per article, Eigenfactor score, impact points, and RG score. Article level metrics or altmetrics are based on Twitter, Facebook, Mendeley, CiteULike, and Delicious which have been discussed. All technical terms used in the Unit have been defined.
Unit 2 deals with analytical tools and indicators used in evaluating scholarly communications. The tools covered are The Web of Science, Scopus, Indian Citation Index (ICI), CiteSeerX, Google Scholar and Google Scholar Citations. Among these all the tools except Indian Citation Index (ICI) are international in scope. ICI is not very much known outside India. It is a powerful tool as far Indian scholarly literature is concerned. As Indian journals publish a sizable amount of foreign literature, the tool will be useful for foreign countries as well. The analytical products with journal performance metrics Journal Citation Reports (JCR®) has also been described. In the chapter titled New Platforms for Evaluating Scholarly Communications three websites i.e. SCImago Journal & Country Rank (SJR) [ScimagoJR.com], eigenFACTOR.org, JournalMetrics.com and one software called Publish or Perish (POP) Software have been discussed.
Article and author level measurements have been discussed in Unit 3. Author and researcher identifiers are absolutely essential for searching databases in the WWW because a name like D Singh can harbour a number of names such as Dan Singh, Dhan Singh, Dhyan Singh, Darbara Singh, Daulat Singh, Durlabh Singh and more. The ResearcherID.com, launched by Thomson Reuters, is a web-based global registry of authors and researchers that individualises each and every name. Open Researcher and Contributor ID (ORCID) is also a registry that uniquely identifies an author or researcher. Both have been discussed in this Unit.
