Iraqi Journal for Computer Science and Mathematics

Over the last decade, the chaotic behaviors of dynamical systems have been extensively explored.Recently, discovering or developing a 2D system of ordinary differential equations (ODEs) capable of exhibitingchaotic dynamical behaviors is an attractive research topic. In this study, a chaotic system with a 2D system ofnonsmooth ODEs has been developed. This system is can exhibit chaotic dynamical behaviors. Its main dynamicalbehaviors, including time-series trajectories, phase portraits of attractors, and equilibria and their stability, have beeninvestigated. The developed system has been verified by an excessive variety of fascinating chaotic behaviors, such aschaotic attractor, symmetry, sensitivity to initial conditions (ICs), fractal dimension, …

Identification Method Of Power Internet Attack Information Based On Machine Learning, Yitong Niu, Korneev Andrei

Iraqi Journal for Computer Science and Mathematics

To solve the problem of large recognition errors in traditional attack information identificationmethods, we propose a machine learning (ML)-based identification method for electric power Internet attackinformation. Based on the Internet attack information, an Internet attack information model is constructed, theidentification principle of the power Internet attack information is analysed based on ML, hash fixing is conducted toensure that the same attack information will be assigned to the same thread and that the deviation generated by noisecan be avoided so that the real-time lossless processing of the power Internet attack information can be ensured. Thevulnerability adjacency matrix is constructed, and the …

Modelling The Throttle Effect In A Mine Drift, Rickard Hansen

Journal of Sustainable Mining

The throttle effect is a phenomenon, which may occur during a fire underground, causing unforeseen smoke spread. This paper focuses on the modelling of the throttle effect in a mine drift, using a CFD software. The aim of the paper is to investigate whether the CFD tool is able to predict and reproduce the throttle effect for fire scenarios underground. Experimental data from fire experiments in a model-scale mine drift and modelling results from a CFD model were used during the analysis. It was found that the CFD model was not able to fully reproduce the throttle effect for fire …

Boswellia sacra Flueck (family Burseraceae) tree is wounded to produce frankincense. We report its de novo assembled genome (667.8 Mb) comprising 18,564 high-confidence protein-encoding genes. Comparing conserved single-copy genes across eudicots suggest >97% gene space assembly of B. sacra genome. Evolutionary history shows B. sacra gene-duplications derived from recent paralogous events and retained from ancient hexaploidy shared with other eudicots. The genome indicated a major expansion of Gypsy retroelements in last 2 million years. The B. sacra genetic diversity showed four clades intermixed with a primary genotype—dominating most resin-productive trees. Further, the stemtranscriptome revealed that wounding concurrently activates phytohormones signaling, …

Isoform switching events with predicted functional consequences are common in many cancers, but characterization of switching events in esophageal adenocarcinoma (EAC) is lacking. Next-generation sequencing was used to detect levels of RNA transcripts and identify specific isoforms in treatment- naïve esophageal tissues ranging from premalignant Barrett’s esophagus (BE), BE with low- or high-grade dysplasia (BE.LGD, BE.HGD), and EAC. Samples were stratified by histopathology and TP53 mutation status, identifying significant isoform switching events with predicted functional consequences. Comparing BE.LGD with BE.HGD, a histopathology linked to cancer progression, isoform switching events were identified in 75 genes including KRAS, RNF128, and WRAP53. Stratification …

Articles

The antimicrobial property is the key feature of active packaging. Biological macromolecules such as tannic and gallic acids are naturally found in plants such as tea, fruits, berries, and grapes. The incorporation of tannic acid (TA) and gallic acid (GA) in the biodegradable polymer blend Poly Lactide-Poly (Butylene Adipate-Co-Terephthalate) (PLA-PBAT) was used in this study to assess the potential of active packaging. TA and GA (10 wt%) composite films showed a 65%–66% increase in the UV barrier property. The tensile strength value increased after the incorporation of TA and GA (10 wt%), respectively. Overall, 1.67 and 2.2 log reductions in …

Analysis Of Human Gait Cycle With Body Equilibrium Based On Leg Orientation, Muhammad Asif, Muhammad Abdullah Tayyab, Muhammad Hammad Shahid, Usama Arif, Mohsin Islam Tiwana, Umar Shahbaz Khan, Waqar Shahid Qureshi

Articles

Gait analysis identifies the posture during movement in order to provide the correct actions for a normal gait. A person's gait may differ from others and can be recognized by specific patterns. Healthy individuals exhibit normal gait patterns, while lower limb amputees exhibit abnormal gait patterns. To better understand the pitfalls of gait, it is imperative to develop systems capable of capturing the gait patterns of healthy individuals. The main objective of this research was to introduce a new concept in gait analysis by computing the static and dynamic equilibrium in a real-world environment. A relationship was also presented among …

Human Gait Recognition Subject To Different Covariate Factors In A Multi-View Environment, Asif Asif, Mohsin I. Tiwana, Umar S. Khan, Muhammad W. Ahmad, Waqar Shahid Qureshi, Javaid Iqbal Javaid Iqbal

Articles

Human gait recognition system identifies individuals based on their biometric traits. A human’s biometric features can be grouped into physiologic or behavioral traits. Biometric traits, such as the face [1], ears [2], iris [3], finger prints, passwords, and tokens, require highly accurate recognition and a well-controlled human interaction to be effective. In contrast, behavioral traits such as voice, signature, and gait do not require any human interaction and can be collected in a hidden and non-invasive mode with a camera system at a low resolution. In comparison with other physiological traits, one of the main advantages of gait analysis is …

Gamifying Structural Analysis Assessments For First Year Architecture Engineering Students, Amany G. Micheal Prof.

Centre for Advanced Materials

Structural Analysis module is a challenge for both teachers and students. The module content is usually presented to students in the form of a set of equations when solved, the structure of internal forces are obtained. Usually, the assignments adopted in such modules are paper-based exams. Such a strategy may assess the capacity of the students to employ different sets of equations to solve a problem. However, this is not enough for a vivid educational atmosphere. Transforming these equations to digital simulations is the best solution for the education process. Digitalization is more appealing to nowadays students and it gives …

A Combined Electrochemical-Biological System For The Production Of Liquid Fuel From Co2, Elizabeth Hann

Link Foundation Energy Fellowship Reports

Biological photosynthesis is the origin of our liquid transportation fuels, from petroleum to corn ethanol. Biological photosynthesis has an efficiency of approximately 1% for the conversion of photons from sunlight to biomass1. Increasing the energy efficiency of biomass production (solar-to-biomass conversion) would allow for biomass, and biofuels, to be produced using less resources. Artificial photosynthesis seeks to overcome the limitations of biological photosynthesis, including low efficiency of solar energy capture and poor carbon dioxide reduction, and could provide an alternative route for biomass production. A two-step electrochemical process converts CO2 to acetate. Acetate is a soluble, two-carbon substrate that can …
