No full textShirin Ashraf is a postdoctoral research associate at the University of Glasgow studying novel viruses from Uganda and other parts of Africa. She took part in HERStory Makers 2022.What is HERStory Makers?HERStory Makers is a social media competition for female-identifying early career researchers to share their research, their career journeys, and to inspire the next generation. Winners are selected by public vote. HERStory Makers is also part of EXPLORATHON, Scotland's contribution to European Researchers' Night.In 2022-23, EXPLORATHON was supported by the Engineering & Physical Sciences Research Council [grant number EP/X020894/1].Author contributions to contentShirin Ashraf conceived, planned, and recorded the video content. Kirsty Ross edited the video content to insert HERStory Maker credits, add subtitles, and maintain video length below Twitter/X limit of 2 mins and 20 secs, prior to scheduling the social media posts.</p
IoD swarms collision avoidance via improved particle swarm optimization
No full textDrones flights have been investigated widely. In the presence of high density and complex missions, collision avoidance among swarm of drones and with environment obstacles becomes a challenging task and indispensable. This paper aims to enhance the optimality and rapidity of three dimensional IoD path generation by improving the particle swarm optimization (PSO) algorithm. The improvements include using chaos map logic to initialize the population of PSO. Also, adaptive mutation is utilized to balance local and global search. Then, the inactive particles are replaced by new fresh particles to push the solution toward global optimal. Furthermore, Monte Carlo simulation is carried out and the results are compared with slandered PSO and with recent work CIPSO. The results exhibit significant improvement in convergence speed as well as optimal solution which prove the ability of proposed method to generate safety path for IoD formation without collision with terrain obstacle and among drones.The authors would like to acknowledge the support of the department of the computer engineering at King Fahd University of Petroleum and Minerals for this work.Ahmed, G (corresponding author), King Fahd Univ Petr & Minerals, Comp Engn Dept, Dhahran, Saudi Arabia.

Automating the determination of wave speed using the pu-loop method
No full textThe PU-loop (pressure-velocity loop) is a method for determining wave speed and relies on the linear relationship between the pressure and velocity in the absence of reflected waves. This linearity of the PU-loop during early systole, which is directly related to wave speed, has always been established by eye. This paper presents a new technique that establishes this linearity and thus determining wave speed online. Pressure and flow were measured in the ascending aorta of 11 anesthetised dogs. The slope of the PU-loop, indicating wave speed was determined by eye and by using the new technique. The difference between the slopes of the two methods is in the order of 3%. The new technique is convenient and allows for the online assessment of wave speed, which could be used as a bedside tool for the assessment of arterial compliance
Keratoconus : current and future state-of-the-art
No full textThis book provides a practical guide to the most recent advances in the diagnostic management of corneal ectasia.

Clinicians and surgeons seeking a go-to guide on the topic of corneal ectasia will find this book to be an essential resource for the latest developments and predicted future trends in the field. © The Editor(s) (if applicable) and The Author(s)
Architectural Education Today : Cross-Cultural Perspectives
No full textFrom the Introduction: Recent literature on architectural education notes that there are continuous attempts to massage architectural curricula, to reconfigure the structure of the educational process, to test accepted ideas, and to probe future visions. However, research findings reveal some fundamental disagreements over the goals and objectives, structure and contents, and tools and techniques required for architectural education today. Since education is the cornerstone of the profession and since the approach to and the content of that education is the backbone of architectural practice, it is essential to encounter the subject in its broadest sense and to deal with it as a rich field of research whose knowledge base, content, and methods can be examined, questioned, and debated. Very few attempts have been developed over the last decade or so by individual scholars to explore the rituals of education in a systematic, visionary, and research-based manner. This indicates the need for more published research and experiments on architectural education and practice. Architectural Education Today is a response to this lack, and is divided into four parts, each of which seeks to provide an exploration of answers to critical questions that pertain to knowledge, professional practice, educational experiments and experiences, and their supporting tools. The intent is not to provide a blue print on how improvement might occur or to offer ready-made or definitive answers, but to further open architectural education to discussion; a subject that continued for years to get sparse attention.

IMR 665: Management of Audio Visual Records & Archives. Individual assignment: Article summary / Zuheir Ashraf Zakaria
No full textArticle on:
Article 1 - “Audio-visual piracy: towards a study of the underground networks of cultural globalization”
Article 2 - “Audiovisual Piracy, Informal Economy, and Cultural Globalization”
This article summary comprises of two article of the same author with a full name of Tristan Mattelart. The first article published on 2009 entitled; “Audio-visual piracy: towards a study of the underground networks of cultural globalization”, while the second article that were published on the year 2011 entitled; “Audiovisual Piracy, Informal Economy, and Cultural Globalization”. These two article consist of 19 and 16 pages consecutively. Both of these article discuss the cultural industries threat it presents to the western world and the underground networks it related to. Although both of these articles discuss the steps taken mainly by the US government to combat these problem in order to protect their intellectual property rights of US companies. Since both of the article are being authored by the same author, we can see that the later article; “Audiovisual Piracy, Informal Economy, and Cultural Globalization” often mention and cite the older article as a reference

The Pherobase
No full textThe Pherobase was developed by Dr. Ashraf El-Sayed, a research scientist at HortResearch in New Zealand, with the primary objective of providing "coverage of the literature published on chemical communication in insects." The Pherobase is intended for use by both scientific and non-scientific communities and currently contains "over 10000 entries, around 3000 molecules, and over 32000 static html pages that make it the world's largest database of behavior modifying chemicals." The site contains multiple Insect indices for such categories as Order, Family A-Z, and Species; References indices such as Discovery by Author, Discovery by Year, and References A-Z; and indices for Compounds, Compounds by Family, and Compounds by Genus. The site also contains a Contribution Form, and number of online forums relating to The Pherobase
