Parameter estimate and adaptive control of DARMA systems with uniform quantized output data
Authors: Jing Lida
Published: October 2023

This paper is concerned with parameter estimate and adaptive control
problems of deterministic autoregressive moving average (DARMA) systems
on the basis of quantized data of system output signals which are
generated by a kind of uniform quantizer. By designing system input
signals, the extended least-squares (ELS) algorithm with uniform output
observations is proved to yield bounded estimation errors under some
mild assumptions. Moreover, the adaptive tracking controller under
inaccuracy observations are also designed. To analyse the properties of
tracking error, I use the expanded form of ELS and research the
properties of quantization noise. In addition, I give the expression of
tracking error and show how it depends on the size of quantization step
when the quantization step satisfies some conditions. A numerical
example is supplied to demonstrate the theoretical results.
The Design of Fuzzy Logic Controller for Efficiency Improvement of Capacitive Power Transfer System

Published: October 2023

This study introduces a control strategy to enhance the efficiency of
Capacitive Power Transfer (CPT) systems, even when the load varies.
Compared to Inductive Power Transfer Systems (IPT), CPT systems are
known for being flexible and safe. However, their efficiency is
significantly affected by load variations. Therefore, to address this
problem, we propose using a Fuzzy Logic Controller (FLC) to adjust the
operating frequency of the MOSFET based on Output Current and Output
Voltage inputs of the CPT circuit. To be specific, a relationship
between load changes and output variations is first established and the
If-Then rules is then proposed for the FLC. Through simulations of the
Class E CPT system, both with and without the FLC, we demonstrate that
the FLC-equipped CPT system maintains 92% efficiency despite a +15%
load variation. In contrast, the CPT system without FLC achieves only
48% efficiency under the same conditions. This underscores the FLC’s
effectiveness in enhancing CPT system efficiency amidst varying loads.

Authors: Ospina Paula , Onazi Mona M. Al , McNeely Margaret
Published: October 2023

Chemotherapy-induced peripheral neuropathy (CIPN) is a frequent and
debilitating side effect seen in children undergoing chemotherapy.
Objective: To synthesize the evidence on physiotherapy for CIPN symptoms
and deficits in children with cancer. Methods: A systematic review was
conducted with the following PICOS approach: children with cancer,
physiotherapy, control group or standard care, and randomized controlled
trials and controlled clinical trials comprising range of motion, muscle
strength, motor function, balance, gait, functional mobility, foot
posture, pain, and adverse events outcomes. Searches were conducted in
five electronic databases, reference lists, grey literature, and
clinical trial websites in May 2023. Results: Nine full-text studies met
the inclusion criteria. Although benefits were seen for some outcomes
related to physical function, evidence is not at a stage to provide
recommendations for clinical practice. Conclusion: Research is needed
that includes CIPN-specific outcome measures to better inform the
incidence, natural progression, and the benefits of physiotherapy
interventions.
An alternative potential method for mixed steady state elastic oscillation problems
Authors: Natroshvili David , Mrevlishvili Maia , Tediashvili Zurab
Published: October 2023

We consider an alternative approach to investigate three-dimensional
exterior mixed boundary value problems (BVP) for the steady state
oscillation equations of the elasticity theory for isotropic bodies. The
unbounded domain occupied by an elastic body, Ω − ⊂ R 3 , has a compact
boundary surface S = ∂ Ω − , which is divided into two disjoint parts,
the Dirichlet part S D and the Neumann part S N , where the displacement
vector (the Dirichlet type condition) and the stress vector (the Neumann
type condition) are prescribed respectively. Our new approach is based
on the classical potential method and has several essential advantages
compared with the existing approaches. We look for a solution to the
mixed boundary value problem in the form of a linear combination of the
single layer and double layer potentials with densities supported on the
Dirichlet and Neumann parts of the boundary respectively. This approach
reduces the mixed BVP under consideration to a system of boundary
integral equations, which contain neither extensions of the Dirichlet or
Neumann data nor the Steklov-Poincaré type operator involving the
inverse of a special boundary integral operator, which is not available
explicitly for arbitrary boundary surface. Moreover, the right-hand
sides of the resulting boundary integral equations system are
vector-functions coinciding with the given Dirichlet and Neumann data of
the problem in question. We show that the corresponding matrix integral
operator is bounded and coercive in the appropriate L 2 -based Bessel
potential spaces. Consequently, the operator is invertible, which
implies unconditional unique solvability of the mixed BVP in the class
of vector-functions belonging to the Sobolev space [ W 2 , loc 1 ( Ω −
) ] 3 and satisfying the Sommerfeld-Kupradze radiation conditions at
infinity. We also show that the obtained matrix boundary integral
operator is invertible in the L p -based Besov spaces and prove that
under appropriate boundary data a solution to the mixed BVP possesses C
α -Hölder continuity property in the closed domain Ω − ‾ with α = 1 2 −
ε , where ε>0 is an arbitrarily small number.
Disentangling cerebellar and parietal contributions to gait and body schema: a repetitive transcranial magnetic stimulation study
Authors: Bertuccelli Margherita , Bisiacchi Patrizia , Felice Alessandra Del
Published: October 2023

The overlap between motor and cognitive symptoms resulting from
posterior parietal cortex (PPC) and cerebellar lesions can mask their
relative contribution in sensorimotor integration processes. This study
aimed to identify distinguishing motor and cognitive features to
disentangle PPC and cerebellar involvement in two sensorimotor-related
functions: gait and body schema representation. Thirty healthy subjects
were enrolled and randomly assigned to PPC or cerebellar stimulation.
Sham stimulation and 1Hz repetitive Transcranial Magnetic Stimulation
were delivered over P3 or cerebellum before balance, walking and
distance estimation tasks. Each trial was repeated with eyes open (EO)
and closed (EC). Gait spatiotemporal and kinematic variables were
recorded by eight inertial measurement units. Instability increased in
both groups after real stimulation vs. sham stimulation: PPC inhibition
increased the instability in EC conditions, while cerebellar inhibition
affected both EC and EO stability. Spatiotemporal variability increased
after real stimulation (EC vs EO) in both groups but mostly affecting
different parameters. Increased kinematic variability of ankle and knee
angles was observed in both groups after real stimulation (EC vs. EO).
Distance overestimation was observed after real stimulation (EC) only in
the PPC group. Stability, gait variability and distance estimation
parameters can be used to disentangle cerebellar and PPC sensorimotor
integration deficits. Differential diagnosis efficiency can benefit from
this methodological approach.
Whole genome sequencing reveals distinct population structure in a high gene flow marine species, Australasian snapper (Chrysophrys auratus)
Authors: Oosting Tom , Star Bastiaan , Wellenreuther Maren , Ritchie Peter
Published: October 2023

The identification of genetically distinct populations is central to the
management and conservation of wild populations. Whole-genome-sequencing
allows for high-resolution assessment of genetic structure, demographic
connectivity and the impacts of selection acting on different parts of
the genome. Here, we utilise population genomics to investigate the
genetic structure of the Australasian snapper or Tāmure
(Chrysophrys auratus), an ecologically, economically, and
culturally important (taonga) marine fish. We analysed over four million
high-quality SNPs obtained by whole-genome sequencing from 382
individuals collected across its New Zealand range. We identified two
genetic clusters (an eastern and western cluster) with genetic
disjunctions around on either side of the North Island of New Zealand.
These genetic clusters do not match the current fisheries management
areas. Pairwise-F and ADMIXTURE analyses showed the
presence of directional gene flow occurring at both genetic disjunctions
from the East to the West cluster. We hypothesize that major ocean
currents are limiting the dispersal of snapper at these genetic
disjunctions. The heterogeneous coastal environment is also likely
driving evolutionary change. A genome scan identified four significantly
divergent genomic regions between genetic clusters. A diverse pattern of
genetic variation in these regions implies that different evolutionary
processes drive local adaptation in these clusters. Identification of
candidate genes in these regions also provides a tentative connection to
which traits may be under selection. Our results provide novel insights
into New Zealand’s coastal environment influences evolutionary
processes, and valuable information for effective management of the
snapper fisheries.

Salviarosmarinus, a commonly known aromatic plant
belonging to the Salvia genus, is valued for its medicinal
properties, derived primarily from the terpenoids present in its leaves.
We have successfully created a chromosome-level genome assembly of
S. rosmarinus, covering 1.24 Gb, with a scaffold N50 value of
107.45 Mb and 61,717 annotated protein-coding genes. Our analysis
highlights a recent whole genome duplication (WGD) event as the primary
driver of genomic rearrangement and fusion following speciation. As a
result of the WGD, key genes involved in monoterpene biosynthesis, such
as HMGR, 1,8-cineole synthase, and limonene synthase, underwent
tandem duplication and double punctuation. Limonene synthase experienced
a nonpolar mutation that favored structural diversity in monoterpene
biosynthesis, while 1,8-cineole synthase underwent a polar mutation that
favored 1,8-cineole(eucalyptol) accumulation. In addition, our analysis
revealed differences in the mechanisms of diterpene biosynthesis between
S. rosmarinus and S. miltiorrhiza, as evidenced by the
tandem duplication, covariance, and high-level expression of genes
essential for carnosol biosynthesis, specifically CYP76AK6–8.
These findings no punctuation for understanding the molecular-level
diversity of terpenoids in S. rosmarinus and will facilitate
molecular breeding and quality improvement efforts for this economically
important plant.

Published: October 2023

Seed priming and citric acid (CA) supplementation on germination and seedling growth of soybeans were investigated. Soybean seeds were primed with distilled water (control), 1 mM CA (CA1), or 2 mM CA (CA2) and then placed for germination in Petri dishes containing distilled water or 150 mM NaCl (SS), alone or in combination with 1 mM or 2 mM CA. Germinated seeds were placed in hydroponic pots using a similar treatment regimen to that specified for the Petri dishes to obtain seedling growth and biochemical parameters. Salt stress significantly lowered germination, growth traits, relative water content (RWC), and photosynthetic pigment. When soybean seeds were primed with CA under salt stress, the germination rate, final germination percentage, seed vigor index, and number of lateral roots significantly increased. Moreover, supplementation of CA significantly increased fresh and dry shoot and root weight, plant height, RWC, and photosynthetic pigments compared to salt-treated plants. The results also displayed that salt stress considerably increased hydrogen peroxide (H2O2) and malondialdehyde (MDA) contents compared to control plants. Spraying of CA1 and CA2 significantly lowered the levels of H2O2 and MDA in salt-treated plants. Both hierarchical clustering and PCA revealed that the effects of salt stress and CA on germination, growth characteristics, photosynthetic pigments, H2O2, and MDA concentrations strongly interacted with one another. According to the findings, CA could be applied as a seed priming and exogenous agent to help soybeans grow more quickly when exposed to salt stress.

Published: October 2023

Paper is a widely used material and common recyclable household waste in waste disposal, which gets more attention nowadays for the misclassification of recyclable waste. In this work, an online source tracing system combined with machine learning algorithms to identify and classify the smoke of waste paper incineration based on laser-induced breakdown spectroscopy (LIBS) was established. Four types of waste paper, including tissue, corrugated paper, printing paper, and newspaper, were taken as examples. The smoke of four different waste papers was detected by LIBS and then further analyzed. The detected spectra with C, N, O, Mg, Al, and Ca could hardly be distinguished artificially. The random forest algorithm and the linear discriminant analysis were introduced to classify the smoke, and its accuracy reached 95.83%. The results indicate that source tracing of waste paper can be realized by identifying and classifying the smoke via the developed system. This could provide some reference for helping us to monitor the effectiveness of waste classification and incineration and monitor the atmosphere pollution.

Det er allerede gjort omfattende forskning på sammenhengen mellom personlighet og ledelse, også i Norge. En gruppe ledere som har blitt viet mindre oppmerksomhet, er ledere av frivillige studentorganisasjoner. I tillegg har en rekke teknologiske studentorganisasjoner etablert seg de siste 10–15 årene i Trondheim. I denne artikkelen vil vi beskrive personlighetstrekkene til ledere i frivillige studentorganisasjoner og sammenholde funnene med hva som er funnet blant ledere i andre organisasjoner. Videre vil vi illustrere likheter og forskjeller mellom ledere i tekniske studentorganisasjoner kontra de mer tradisjonelle studentorganisasjonene. Utvalget består av 136 studenter med lederverv i frivillige studentorganisasjoner. Studentene ble rekruttert blant studenter som tok emnet IØ1004 Topplederrollen i frivillige organisasjoner ved NTNU i årene 2021, 2022 og 2023. Resultatene våre viser at ledere i frivillige studentorganisasjoner skårer høyere enn gjennomsnittet i befolkningen på personlighetstrekkene ekstroversjon og samvittighetsfullhet, noe som også går igjen hos tidligere studier av norske ledere. Ledere i tekniske studentorganisasjoner skåret lavere enn andre studentledere på ekstroversjon, men noe høyere på samvittighetsfullhet. Ledere i frivillige studentorganisasjoner var samlet sett medarbeiderorientert. Selv om det var små og usikre forskjeller i lederstil mellom ledere i tekniske og ikke-tekniske organisasjoner, var det likevel en tendens til at ledere i tekniske studentorganisasjoner skåret noe høyere på endringsorientering enn ledere i ikke-tekniske organisasjoner, noe som virker rimelig med tanke på hvor sentralt utviklingen av nye teknologiske modeller er i disse organisasjonene. Resultatene antyder at personlighetstrekkene ekstroversjon og åpenhet for nye ideer oppfattes og fungerer annerledes i tekniske organisasjoner enn i andre studentorganisasjoner, men her ser vi frem til videre forskning på dette og andre tema om ledere i frivillige organisasjoner, inkludert studentorganisasjoner, i Norge.
Økonomisk vekst i lys av klima, natur, inntektsfordeling og lykke
Authors: Vale Per Halvor
Published: October 2023

I denne artikkelen stilles kritiske spørsmål til ulike sider ved økonomisk vekst. I Norge har veksten de siste 20–30 årene vært mye knyttet til utviklingen av en oljesektor. Veien til økonomisk vekst har også gått gjennom bruk av natur og naturgoder. Er dette blitt gjort i samsvar med samfunnsøkonomiske kriterier? Videre, er fortsatt økonomisk vekst forenlig med bærekraft og klimamålene? Er det noen sammenheng mellom den mer skjeve inntektsfordeling og den økonomiske veksten? Disse spørsmålene kan ikke analyseres isolert. Utover i artikkelen kommer kompleksiteten og samspillet fram. I siste kapittel vil fordelene og ulempene med økonomisk vekst bli sett sammenheng og gi svar på om fortsatt økonomisk vekst er ønskelig, eller om kursen framover må legges om.
The Effect of Coenzyme Q10 on Oxidative Stress and Endoplasmic Reticulum Stress in an Experimental Diabetes Model
Authors: Sait Toprak Muhammet
Published: October 2023

Diabetes is the 8th leading cause of death worldwide. The greatest increase in rates has been seen in low and middle-income countries. Urbanization and lifestyle changes such as an increase in sedentary lifestyles, increase in the intake of foods with high energy but poor nutrition levels have caused a high incidence of the disease worldwide. Treating the mechanisms involved in the pathogenesis of diabetes with nutrients such as antioxidants can reduce further complications of the disease. This study tests whether hyperglycemia triggers endoplasmic reticulum stress in the liver and brain tissues of rats and the possible role of oxidative stress in this pathway. We investigated the relationship between oxidative and endoplasmic reticulum stress via the TWEAK pathway, and how the coenzyme Q10 affects further diabetic complications. We examined oxidative stress markers (Oxidized Glutathione, Reduced Glutathione) in the liver and brain tissues of rats in the control, diabetic, and diabetic antioxidant groups by ELISA method. We also determined endoplasmic reticulum stress markers (PERK, ATF6, GRP78) and the TWEAK molecule by the Western Blott method in the same experimental groups. Our results underlined that coenzyme Q10 had a significant and positive effect on oxidative and endoplasmic reticulum stress parameters, and TWEAK levels. We also found a more robust positive correlation between oxidative and endoplasmic reticulum stress parameters for the liver compared to the brain. However, a significant positive correlation was also seen between TWEAK and endoplasmic reticulum stress of the brain.

Published: October 2023

Tooth ankylosis is a disastrous sequela of dental trauma that often leads to unaesthetic tooth appearance, especially in the anterior region. The altered dental aesthetic can significantly impact young adolescents’ quality of life and general well-being. This case describes a clinical method to address the aesthetic concern of a 14-year-old young adolescent with a displaced traumatized ankylosed tooth using a preformed transparent polypropylene thermoplastic template. This template allowed recontouring of the tooth in terms of shape and alignment. This method provides an inexpensive option to correct the contour and alignment of a tooth with minimal material wastage, shortening the clinical working time and pleasing aesthetic outcome. As clinicians, one should explore all options and possibilities to work out a solution for a problem. The preformed transparent polypropylene thermoplastic template is one such option that can be used to address dental aesthetics.

Wireless networks are the most developed progress than other technologies because of cost-effective, flexibility, mobility, and easy deployment. Despite these benefits, wireless networks suffer from different types of challenges and vulnerabilities. During past decades, IEEE, IETF and, Wi-Fi Alliance Institute developed a lot of wireless security protocols including WEP, WPA, WPA2, WPA3, 802.1x standards. Besides, these protocols bring the most solutions for wireless security challenges, still, these protocols are vulnerable against the different types of attacks and threats (Dictionary attacks and Rogue access points). Thus, in this paper after doing a survey and finding the challenges in the case of Afghanistan, I propose solutions regarding specific challenges. The proposed solutions are Kismet and Snort for rogue-AP and dictionary attack detection and prevention. Since these proposed solutions are implemented in the least cost due to open source and free attitude, the proposed solutions are implementable in every Wi-Fi environment in Afghanistan.
MORE HUMAN THAN HUMAN: POSTHUMANISM IN LITERARY DISCOURSE
Authors: Gumanay Jorisse Campado
Published: October 2023

“What makes us human?” Throughout time, people have been preoccupied with this question, believing that humans are at the pinnacle of the world. Today, technology blurs the boundaries of what is considered “natural” versus “enhanced,” leading to a fallout with the limited views of humanism and modernity. This paper explores the many views on posthumanism that have been established by several thinkers to attempt to understand the concept. An illustrative text is then used to elucidate the implication of the posthumanist thought in literature. Posthumanist themes are prevalent in science fiction, embodying people’s collective anxiety toward the looming future of humanity, such as in the works of Philip K. Dick. The story “The Electric Ant” poses existential questions on the nature of reality and our place in it, with highly posthumanist themes such as the presence or assimilation of robots in human societies. Posthumanism is as yet a complex and broad field of study, challenging our notions of what it means to be human and alive, and making us ask questions about how the present and future of technology could shape our human existence.

Lipid metabolism disorders play an important role in the development of a number of diseases associated with obesity. However, not all obese people have the traditional abnormal clinical plasma lipid levels, which is especially common in children and adolescents. Given this controversial relationship it is necessary to clarify the new lipid biomarkers in obesity. From this point of view, of particular interest is lipidomics, which allows identifying the diversity of different types of lipids presented in a cell, tissue, biological fluid or in the entire body using tandem mass spectrometry. The human lipidomic profile reflects lipid metabolism, including the early phase of pathophysiological changes associated with the formation of the obesity phenotype. Studying the connection between the lipidome and metabolic plasticity can provide new insight into the biological mechanisms of the development of obesity and its complications, the relationship between fat and carbohydrate metabolism in the development of insulin resistance, disruption of the functioning of intestinal incretins (cholecystokinin, glucagon-like peptide 1 and 2 etc.). From a public health perspective, a thorough understanding of the pathophysiological changes that lead to obesity at the earliest stage will have far-reaching promise for slowing the enormous global incidence of obesity and type 2 diabetes mellitus. This bibliographical review was conducted using the PubMed, Google Scholar and Cyberleninka databases through 2013-2023 sources.

Cardiac manifestations in the acute phase and complications of COVID-19 in children, especially newborns, have not been sufficiently studied as yet. The purpose of this research was to determine the nature of damage to the cardiovascular system (CVS) in newborns from mothers who had a new coronavirus infection at different stages of pregnancy and who were infected after birth. Materials and methods used: a single-center observational comparative study with elements of retrospective analysis. The 3 groups of full-term newborns of 37 each were formed as follows: the main group 1 (A) of newborns from mothers who had a laboratory-confirmed new coronavirus infection in the 1st to 2nd trimesters of pregnancy; the comparison group 2 (B) of newborns with a laboratory-confirmed new coronavirus infection from mothers who had COVID-19 in the peripartum period; and the control group 3 (C) of practically healthy newborns. The frequency of various types of CVS lesions (myocarditis, rhythm and conduction disorders, perinatal CVS lesions) as well as the frequency of occurrence of signs of electrophysiological myocardial instability, hemodynamic disorders and increased levels of cardiac-specific enzymes were assessed. Results: newborns from mothers who suffered a new coronavirus infection during pregnancy are more likely than newborns from physiologically healthy pregnancy and childbirth to develop cardiac problems (heart failure (p=0.025), cardiac arrhythmias (p<0.001), specified congenital anomalies of the cardiac septum (p1-3<0.001), other specified congenital heart anomalies (p1-3=0.032) and other cardiovascular disorders that arose in the perinatal period (p<0.001)), in particular, maladaptive disorders of the cardiovascular system with signs of electrical instability of the myocardium, dilation of the heart cavities and increased levels of cardiac-specific enzymes, which required the exclusion of myocarditis. Conclusion: the identified changes in the cardiovascular system dictate the need for monitoring of newborns from mothers with COVID-19 with dynamic CVS assessment.

Authors: Edwin Mihardja
Published: October 2023

Global clean water crisis is affecting more than 40% population and still increasing. As an archipelago state with large coastal area, Indonesia is however facing the common issue with the clean water shortage. There are still lack of access to clean water and water treatment plant for the community in the coastal area to fulfill their daily needs and drinking water as most water source is brackish water with higher salinity than fresh water. Hence further treatment is required to obtain the clean water and safe for daily consumption. The objectives of this research work are to determine suitable local material for water treatment and alternatively by using reverse osmosis equipment which is expected to reduce salinity of treated water. As methodology used in this research, a physical treatment experiment on the brackish water is conducted through a selected local filter media and by using reverse osmosis equipment with the assistance of internet of thing technology. The research work outcomes demonstrate that treated water by filtering has indicated a clear physical appearance and odorless but no significant improvement on pH and about 3,67% reduction on TDS value and 7.0% on EC value. On the other side, the treatment through reverse osmosis method is showing better result with significant improvement with 99.5% TDS and EC value which can’t be achieved by filtering treatment.

Also, the results showed the regression analysis with an R2 value of 0.9837 indicates satisfactory predictive ability between the experimental results and the predictive values.
High Strain Rate Deformation Behaviour Analysis of Recycled Aluminium Alloys AA6061 Reinforced Alumina Oxide Al2O3 Using Taylor Cylinder Impact Test
Authors: Mohd Nor M. K.
Published: October 2023

The deformation behaviour and fracture mechanism of reinforced recycled aluminium alloy are still an open and exciting area to be explored. Based on this motivation, this paper investigates the deformation behaviour, and fracture mode of recycled aluminium alloy AA6061 reinforced alumina oxide at a high strain rate using the Taylor cylinder impact test. The deformation behaviour analysis was also compared with the behaviour shown by the recycled AA6061 without reinforcement material. The geometric profile of the deformed specimen was used to analyse the deformation behaviour and fracture mode, including the relation with the impact deformation characteristics. Three different fracture modes were observed within the impact velocity of 190-370 m/s. The reinforced recycled AA6061 showed a better strength performance with higher critical impact velocity than the unreinforced recycled AA6061. The damage deformation behaviour was studied using Scanning Electron Microscope (SEM). The results showed that the damage agents were initiated, grew, and coalesced during mild ductilitydeformation. Damage progression was finally examined using ImageJ software and characterized average voids size. The decrement of voids size was quite significant under tensile splitting and petalling fracture modes compared to the mushrooming due to severe localized plastic strain deformation around this plastic deformation zone. Therefore, the increasing impact velocity increases the severity of damage progression of the reinforced recycled AA6061.
Development of an Order Processing System using Google Sheets and Appsheet for a Malaysian Automotive SME Factory Warehouse
Authors: Mohd Rusli Mohd Hazri
Published: October 2023

The automotive industries in Malaysia have grown well and developed many suppliers in their supply chain including Small Medium Enterprise (SME). The order handling process at a supplier's factory has become one of the most critical areas in the supply chain. Adaptation to technology such as IoT enables the automotive supplier to better manage their customer orders and avoid mistakes that affect the supply chain. In order to improve the order processing activities, a study has focused on developing a mobile device application using Google Appsheet and Google Sheets as a cost-effective system for managing supply orders. A study was conducted in one of Malaysian SME automotive companies, which manages the orders manually by using a log book with a lot of recording and redundant work. By using Google Sheets, all the information and data involved in order processing activities is imported and digitized. Then, a mobile application is created using Appsheet so that the ordering activities and processing can be completed on a mobile device. All information gathered by the mobile app (Google Appsheet) is immediately saved in Google Sheets on an Excel-based database, allowing for further data analysis. The research conducted has managed to integrate these two applications into a system for Malaysia's SME factory to manage the ordering activities in the automotive supply chain. This system enables the user to shorten their order processing time since data is captured in real time and mistakes due to manual error can be avoided.
Bending and Buckling Analysis of Functionally Graded Plates using a New Shear Strain Function with Reduced Unknowns
Authors: Meftah Ali Meftah
Published: October 2023

In this article, functionally graded plates’ buckling and bending analyses are investigated using a new shape function. The parabolic transverse shear stresses throughout the thickness are regarded by this function as meeting the shear stress-free surface conditions and enabling an accurate distribution of shear deformation according to the thickness of the plate without integrating shear correction factors. Compared to previous shear theories, this higher-order shear theory has the fewest unknowns. The equations for the functionally graded plates are produced by employing the Hamiltonian principle, and the solutions are obtained using Napier’s technique. The outcomes of the current analysis are provided and contrasted with those found in the literature.

Published: October 2023

The low density, low expansion coefficient, and strong corrosion resistance at room temperature of Aluminium alloys have made them a popular choice for engineering applications. In this study, Aluminium AA2024 alloys are prepared with different weight contents of ceramic material, titanium oxide (TiO2) nanoparticles (0%, 2.5%, 5%, and 7.5% wt.) of a particle size of 30 nm using the metal stir casting method. The hardness property and wear resistance with the effect of heat treatment are investigated using a pin-on-disc wear device for both the base alloy and the reinforced alloys. The result shows the prosperity of 5wt.% of TiO2 to attain the optimum hardness and wear resistance. Using the optimum content of TiO2 and heat treatment, the hardness and wear resistance of 5wt.% TiO2-AA2024 nanocomposite has been significantly improved after heat treatment over the unreinforced Aluminium matrix. Statistically, the hardness and wear resistance are improved by 68% and 22%, respectively. This is due to an increased number of fine precipitates besides their uniformly distributed after heat treatment. Furthermore, casting AA2024 Aluminium alloy material mainly has S (Al2CuMg) and Al3TiCu phases. The appearance of a large number of S phases causes a significant improvement in the properties of the alloy.

Background: It is a common fact that the rapid development of technology influenced many aspects of the world, including mass communication. Television, as the most popular and familiar broadcast media in Indonesia, has experienced several changes due to the presence of advanced technology. One of the significant transformations is the transition from analog to digital broadcasting systems. The new era of digital broadcasting could improve the performance and quality of digital television itself. Purpose: This recent study aimed to obtain an overview of the realization carried out by one of the local private broadcasting institutions in Banten, JPM TV. Methods: Using a qualitative case study along with in-depth interviews and observation as data collection techniques, this study examines JPM TV from various aspects in realizing digital TV broadcasts in Banten Province. Results: The study’s findings highlighted that JPM TV strives to realize digital broadcasting by gradually replacing equipment with tools that support digital broadcasting and elements of human resources trained and prepared with special internal and external training. JPM TV also collaborated with LPPM (Mix Broadcasting Organizing Agency), namely Mix Metro TV. The ongoing process is coordinated with the government. Obstacles faced during the migration process are the socioeconomic conditions of the people who have not been able to support the digital broadcasting process, which is characterized by the difficulty of obtaining digital broadcasting at relatively low prices; besides that, it is also necessary to increase the capacity of Human Resources (HR) so that television shows are more comfortable to watch. Implications: One of the implications is that the government must innovate to provide incentives that can stimulate the readiness of the digital broadcasting ecosystem.

Background: The 2022 Cannes Film Festival was held from May 17 – 28, 2022, in Cannes, France. The 2022 Cannes Film Festival succeeded in attracting public attention, shown through tweets using #Cannes2022 uploaded in various languages, which show diversity. Purpose: This study aims to determine the distribution of the #Cannes2022 data at the actor level and the diversity of languages used in the #Cannes2022. Methods: The method of this research is a mixed method by combining quantitative and qualitative methods. Quantitative methods were used to obtain 2,500 tweets using the Netlytic application. Qualitative methods were used to analyze the language used in those tweets. Results: The results of this study indicate that @festival_cannes, @21metgala, @iuteamstarcandy, and @filmupdates are famous and important actors because they always provide updates related to Cannes 2022. Those actors initiate the #Cannes2022 communication network and become reference material. In the #Cannes2022 communication network, there are 24 languages used, including English, Thai, Japanese, French, and Spanish. English is dominant, with a percentage of 51.96%, followed by French, with a percentage of 31.48%. English and French are dominant because popular actors use them in disseminating information about Cannes 2022. Other languages are not dominant because actors with few followers only upload them. The language used in the #Cannes2022 communication network is already quite diverse but still dominated by English. Implications: Popular actors should use other languages to increase diversity at the Cannes Film Festival.
