Bibliometric Review Of Noc Router Optimization, Priti Shahane, Jayshree Pande

Library Philosophy and Practice (e-journal)

Network on chip (NoC) has been proposed as an emerging solution for scalability and performance demands of next generation System on Chip (SoC). NoC provides a solution for the bus based interconnection issue of SoC, where large numbers of Intellectual Property modules (IP) are integrated on a single chip for better performance. The NoC has several advantages such as scalability, low latency and low power consumption, high bandwidth over dedicated wires and buses. Interconnections between multiple chip cores have a significant impact on the communication and performance of the chip design in terms of region, latency, throughput and power. In …

Collection Development For Graphic Novels In Academic Libraries: Results Of A National Survey, Stephen Finlay

Library Philosophy and Practice (e-journal)

A survey on collection development for graphic novels was sent to 632 collection development librarians and also placed on the Association for Library Collections and Technical Services listserv. Once 200 responses had been received analysis of results began. Findings indicate that while all libraries reported possessing at least some graphic novels and most reported having what they would call a “graphic novel collection,” the medium is still quite uncommon when compared to existing library collections, comprising less than 1% of all books in academic libraries. Further, while it was found that most libraries are currently collecting graphic novels, collection development …

Beyond The Family Tree: Genealogy Instruction As A Gateway To Primary Source Literacy, Deedee Baldwin Jan 2020

Beyond The Family Tree: Genealogy Instruction As A Gateway To Primary Source Literacy, Deedee Baldwin

Library Philosophy and Practice (e-journal)

Say the word “genealogy” in an academic library, and you are bound to see weary librarians and archivists roll their eyes and sigh. But academic librarians can do more than accepting genealogists as a frustrating fact of life: they can recognize a perfect opportunity to teach primary source literacy concepts to a group that is more than open to learning them.

Swimming Of Motile Gyrotactic Microorganisms And Nanoparticles In Blood Flow Through Anisotropically Tapered Arteries, M. M. Bhatti, M. Marin, A. Zeeshan, R. Ellahi, Sara I. Abdelsalam Jan 2020

Swimming Of Motile Gyrotactic Microorganisms And Nanoparticles In Blood Flow Through Anisotropically Tapered Arteries, M. M. Bhatti, M. Marin, A. Zeeshan, R. Ellahi, Sara I. Abdelsalam

Basic Science Engineering

In the present article, we have presented a theoretical study on the swimming of migratory gyrotactic microorganisms in a non-Newtonian blood-based nanofluid via an anisotropically narrowing artery. Sutterby fluid model is used in order to understand the rheology of the blood as a non-Newtonian fluid model. This fluid pattern has the ability to show Newtonian and non-Newtonian features. The mathematical formulation is performed via continuity, temperature, motile microorganism, momentum, and concentration equation. The series solutions are obtained using the perturbation scheme up to the third-order approximation. The resulting solutions are discussed with the help of graphs for all the leading …

Adverse Effects Of A Hybrid Nanofluid In A Wavy Non-Uniform Annulus With Convective Boundary Conditions, H. Sadaf, Sara I. Abdelsalam Jan 2020

Adverse Effects Of A Hybrid Nanofluid In A Wavy Non-Uniform Annulus With Convective Boundary Conditions, H. Sadaf, Sara I. Abdelsalam

Basic Science Engineering

The presented investigation theoretically studies the physical characteristics of a two-dimensional incompressible hybrid nanofluid in a non-uniform annulus where the boundaries are flexible. A mixed convective peristaltic mechanism is implemented to model blood-based nanofluids using two different nanoparticles (Ag + Al2O3). Convective boundary conditions are employed and different forms of nanoparticles are discussed (bricks, cylinders and platelets). The problem is shortened by engaging a lubrication method. Exact expressions for the temperature of cumulative heat source/sink standards, hemodynamic velocity, pressure gradient and streamlines of different shapes of nanoparticles are obtained. Special cases of pure blood and the Al2O3 nanofluid of our …

Business Analytics/Business Intelligence And It Infrastructure : Impact On Organizational Agility, Xiaofeng Chen, Keng Siau Jan 2020

Business Analytics/Business Intelligence And It Infrastructure : Impact On Organizational Agility, Xiaofeng Chen, Keng Siau

Research Collection School Of Computing and Information Systems

This is an empirical research investigating the impact of business analytics (BA) and business intelligence (BI) use, IT infrastructure flexibility, and their interactions on organizational agility. Synthesizing the systems theory and awareness-motivation-capability framework, the authors propose that BA-Use, IT infrastructure flexibility, and their interactions significantly influence organizational agility. The results show the significant association of BA use and IT infrastructure flexibility with organizational agility. The results also suggest that BA use may demand corporations to build a more flexible IT infrastructure. However, the data does not reveal the proposed interaction between the two drivers of organizational agility.

Coupled Rain Streak And Background Estimation Via Separable Element-Wise Attention, Yinjie Tan, Qiang Wen, Jing Qin, Jianbo Jiao, Guoqiang Han, Shengfeng He Jan 2020

Coupled Rain Streak And Background Estimation Via Separable Element-Wise Attention, Yinjie Tan, Qiang Wen, Jing Qin, Jianbo Jiao, Guoqiang Han, Shengfeng He

Research Collection School Of Computing and Information Systems

Single image de-raining is challenging especially in the scenarios with dense rain streaks. Existing methods resolve this problem by predicting the rain streaks of the image, which constrains the network to focus on local rain streaks features. However, dense rain streaks are visually similar to mist or fog (with large intensities), in this case, the training objective should be shifted to image recovery instead of extracting rain streaks. In this paper, we propose a coupled rain streak and background estimation network that explores the intrinsic relations between two tasks. In particular, our network produces task-dependent feature maps, each part of …

Neighbourhood Structure Preserving Cross-Modal Embedding For Video Hyperlinking, Yanbin Hao, Chong-Wah Ngo, Benoit Huet

Research Collection School Of Computing and Information Systems

Video hyperlinking is a task aiming to enhance the accessibility of large archives, by establishing links between fragments of videos. The links model the aboutness between fragments for efficient traversal of video content. This paper addresses the problem of link construction from the perspective of cross-modal embedding. To this end, a generalized multi-modal auto-encoder is proposed.& x00A0;The encoder learns two embeddings from visual and speech modalities, respectively, whereas each of the embeddings performs self-modal and cross-modal translation of modalities. Furthermore, to preserve the neighbourhood structure of fragments, which is important for video hyperlinking, the auto-encoder is devised to model data …
