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
عزیز احمد کے افسانے:نوآبادیاتی ہندوستان میں اشراف کلچر کے عہدِ زوال کی داستان
No full textIn this paper, I have tried to throw light on Aziz Ahmad 's short stories in historical and cultural context on one hand and his social understanding of Muslim Ashraf Culture in Colonial India on the other. Modern Industrial urban city between two world wars is a wide stage of his work plan. He leads his reader towards the decline and decadence of Muslim Ashraf Culture in his various short stories Aziz Ahmad suggests that the moral values of the society though, exist, however they were dying due to prevailing moral crisis. In some of his short stories, Aziz Ahmad appears as a historian, while describing the facts through fiction. Social satire is also an important component of his short stories. The principal theme of his short stories lies in dying Muslim Ashraf culture of colonial India
An investigation of supramolecular synthons in 1,2,4-triazole-3(4H)-thione compounds. X-ray crystal structures, energetic and Hirshfeld surface analysis
No full textA series of four closely related 1,2,4-triazole-3-thione (1-4) compounds was obtained by heterocyclization of thiosemicarbazides under basic catalytic conditions. The crystal structures of the 4-alkyl-5-(substituted-phenyl)-2H-1,2,4-triazole-3(4H)-thione derivatives [4-alkyl = 4-ethyl-5-phenyl (1), 4-hexyl-5-phenyl (2), 4-hexyl-5-p-tolyl (3), and 4-ethyl-5-(2,4,6-trimethoxyphenyl) (4)] have been determined. PIXEL lattice energy calculations revealed that dispersion components make the major contributions, with the coulombic terms also contributing significantly to the total energy. Interaction energies for the inversion dimers involving N?H⋯S=C hydrogen bonds indicate a dominant contribution to packing stabilization coming from the coulombic energy component. Hirshfeld surfaces and 2D-fingerprint plots allowed us to visualize different intermolecular contacts and their relative contributions to the total surface in each compound. The comprehensive analysis of the crystal packing and the energetic features demonstrate the key role of the R2 2(8) supramolecular synthon of the type (···HNCS)2 in the solid state structures of these 1,2,4-triazole-3-thiones.Fil: Saeed, Aamer.

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
