In Malaysia, the engagement of Malaysian Law Enforcement Agencies (MLEA) with this new technology is not evenly distributed. To investigate the factors influencing the adoption of DF in Malaysia law enforcement agencies’ operational environment, this study proposed the initial theoretical framework based on the integration of technology organization environment (TOE), institutional theory, and human organization technology (HOT) fit model. A questionnaire survey was conducted on selected law enforcement agencies in Malaysia to verify the validity of the initial integrated framework. Relative advantage, compatibility, coercive pressure, normative pressure, vendor support and perceived technical competence of technical staff were found as the influential factors on digital forensics adoption. In addition to the only moderator of this study (agency size), any significant moderating effect on the perceived technical competence and the decision to adopt digital forensics by Malaysian law enforcement agencies was found insignificant. Thus, these results indicated that the developed integrated framework provides an effective prediction of the digital forensics adoption by Malaysian law enforcement agencies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20forensics" title="digital forensics">digital forensics</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20forensics%20adoption" title=" digital forensics adoption"> digital forensics adoption</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20information" title=" digital information"> digital information</a>, <a href="https://publications.waset.org/abstracts/search?q=law%20enforcement%20agency" title=" law enforcement agency"> law enforcement agency</a> </p> <a href="https://publications.waset.org/abstracts/103036/organizational-decision-to-adopt-digital-forensics-an-empirical-investigation-in-the-case-of-malaysian-law-enforcement-agencies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103036.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">151</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3526</span> Photocatalytic Oxidation of Gaseous Formaldehyde Using the TiO2 Coated SF Filter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Janjira%20Triped">Janjira Triped</a>, <a href="https://publications.waset.org/abstracts/search?q=Wipada%20Sanongraj"> Wipada Sanongraj</a>, <a href="https://publications.waset.org/abstracts/search?q=Wipawee%20Khamwichit"> Wipawee Khamwichit</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The research work covered in this study includes the morphological structure and optical properties of TiO2-coated silk fibroin (SF) filters at 2.5% wt. TiO2/vol. PVA solution. SEM micrographs revealed the fibrous morphology of the TiO2-coated SF filters. An average diameter of the SF fiber was estimated to be approximately 10µm. Also, it was confirmed that TiO2 can be adhered more on SF filter surface at higher TiO2 dosages. The activity of semiconductor materials was studied by UV-VIS spectrophotometer method. The spectral data recorded shows the strong cut off at 390 nm. The calculated band-gap energy was about 3.19 eV. The photocatalytic activity of the filter was tested for gaseous formaldehyde removal in a modeling room with the total volume of 2.66 m3. The highest removal efficiency (54.72 ± 1.75%) was obtained at the initial formaldehyde concentration of about 5.00 ± 0.50ppm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=photocatalytic%20oxidation%20process" title="photocatalytic oxidation process">photocatalytic oxidation process</a>, <a href="https://publications.waset.org/abstracts/search?q=formaldehyde%20%28HCHO%29" title=" formaldehyde (HCHO)"> formaldehyde (HCHO)</a>, <a href="https://publications.waset.org/abstracts/search?q=silk%20fibroin%20%28SF%29" title=" silk fibroin (SF)"> silk fibroin (SF)</a>, <a href="https://publications.waset.org/abstracts/search?q=titanium%20dioxide%20%28TiO2%29" title=" titanium dioxide (TiO2)"> titanium dioxide (TiO2)</a> </p> <a href="https://publications.waset.org/abstracts/4845/photocatalytic-oxidation-of-gaseous-formaldehyde-using-the-tio2-coated-sf-filter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4845.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">469</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3525</span> Forward Stable Computation of Roots of Real Polynomials with Only Real Distinct Roots</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nevena%20Jakov%C4%8Devi%C4%87%20Stor">Nevena Jakovčević Stor</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivan%20Slapni%C4%8Dar"> Ivan Slapničar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Any polynomial can be expressed as a characteristic polynomial of a complex symmetric arrowhead matrix. This expression is not unique. If the polynomial is real with only real distinct roots, the matrix can be chosen as real. By using accurate forward stable algorithm for computing eigen values of real symmetric arrowhead matrices we derive a forward stable algorithm for computation of roots of such polynomials in O(n^2 ) operations. The algorithm computes each root to almost full accuracy. In some cases, the algorithm invokes extended precision routines, but only in the non-iterative part. Our examples include numerically difficult problems, like the well-known Wilkinson’s polynomials. Our algorithm compares favorably to other method for polynomial root-finding, like MPSolve or Newton’s method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=roots%20of%20polynomials" title="roots of polynomials">roots of polynomials</a>, <a href="https://publications.waset.org/abstracts/search?q=eigenvalue%20decomposition" title=" eigenvalue decomposition"> eigenvalue decomposition</a>, <a href="https://publications.waset.org/abstracts/search?q=arrowhead%20matrix" title=" arrowhead matrix"> arrowhead matrix</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20relative%20accuracy" title=" high relative accuracy"> high relative accuracy</a> </p> <a href="https://publications.waset.org/abstracts/40100/forward-stable-computation-of-roots-of-real-polynomials-with-only-real-distinct-roots" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40100.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">417</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3524</span> A Rapid Prototyping Tool for Suspended Biofilm Growth Media</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Erifyli%20Tsagkari">Erifyli Tsagkari</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephanie%20Connelly"> Stephanie Connelly</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhaowei%20Liu"> Zhaowei Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrew%20McBride"> Andrew McBride</a>, <a href="https://publications.waset.org/abstracts/search?q=William%20Sloan"> William Sloan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Biofilms play an essential role in treating water in biofiltration systems. The biofilm morphology and function are inextricably linked to the hydrodynamics of flow through a filter, and yet engineers rarely explicitly engineer this interaction. We develop a system that links computer simulation and 3-D printing to optimize and rapidly prototype filter media to optimize biofilm function with the hypothesis that biofilm function is intimately linked to the flow passing through the filter. A computational model that numerically solves the incompressible time-dependent Navier Stokes equations coupled to a model for biofilm growth and function is developed. The model is imbedded in an optimization algorithm that allows the model domain to adapt until criteria on biofilm functioning are met. This is applied to optimize the shape of filter media in a simple flow channel to promote biofilm formation. The computer code links directly to a 3-D printer, and this allows us to prototype the design rapidly. Its validity is tested in flow visualization experiments and by microscopy. As proof of concept, the code was constrained to explore a small range of potential filter media, where the medium acts as an obstacle in the flow that sheds a von Karman vortex street that was found to enhance the deposition of bacteria on surfaces downstream. The flow visualization and microscopy in the 3-D printed realization of the flow channel validated the predictions of the model and hence its potential as a design tool. Overall, it is shown that the combination of our computational model and the 3-D printing can be effectively used as a design tool to prototype filter media to optimize biofilm formation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biofilm" title="biofilm">biofilm</a>, <a href="https://publications.waset.org/abstracts/search?q=biofilter" title=" biofilter"> biofilter</a>, <a href="https://publications.waset.org/abstracts/search?q=computational%20model" title=" computational model"> computational model</a>, <a href="https://publications.waset.org/abstracts/search?q=von%20karman%20vortices" title=" von karman vortices"> von karman vortices</a>, <a href="https://publications.waset.org/abstracts/search?q=3-D%20printing." title=" 3-D printing."> 3-D printing.</a> </p> <a href="https://publications.waset.org/abstracts/110148/a-rapid-prototyping-tool-for-suspended-biofilm-growth-media" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110148.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">142</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3523</span> Digital Wellbeing: A Multinational Study and Global Index</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fahad%20Al%20Beyahi">Fahad Al Beyahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Justin%20Thomas"> Justin Thomas</a>, <a href="https://publications.waset.org/abstracts/search?q=Md%20Mamunur%20Rashid"> Md Mamunur Rashid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Various definitions of digital well-being have emerged in recent years, most of which center on the impacts -beneficial and detrimental- of digital technology on health and well-being (psychological, social, and financial). Other definitions go further, emphasizing the attainment of balance, viewing digital well-being as wholly subjective, the individual’s perception of optimal balance between the benefits and ills associated with online connectivity. Based on this broad conceptualization of digital well-being, we undertook a global survey measuring various dimensions of this emerging construct. The survey was administered across 35 nations and 7 world regions, with 1000 participants within each territory (N= 35000). Along with attitudinal, behavioral, and sociodemographic variables, the survey included measures of depression, anxiety, problematic social media use, gaming disorder, and other relevant metrics. Coupled with nation-level policy audits, these data were used to create a multinational (global) digital well-being index. Nations are ranked based on various dimensions of digital well-being, and predictive models are used to identify resilience and risk factors for problem technology use. In this paper, we will discuss key findings from the survey and the index. This work can inform public policy and shape our responses to the emerging implications of lives increasingly lived online and interconnected with digital technology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=technology" title="technology">technology</a>, <a href="https://publications.waset.org/abstracts/search?q=health" title=" health"> health</a>, <a href="https://publications.waset.org/abstracts/search?q=behavioral%20addiction" title=" behavioral addiction"> behavioral addiction</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20wellbeing" title=" digital wellbeing"> digital wellbeing</a> </p> <a href="https://publications.waset.org/abstracts/173534/digital-wellbeing-a-multinational-study-and-global-index" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173534.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">79</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3522</span> Digital Twin Platform for BDS-3 Satellite Navigation Using Digital Twin Intelligent Visualization Technology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rundong%20Li">Rundong Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Peng%20Wu"> Peng Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Junfeng%20Zhang"> Junfeng Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhipeng%20Ren"> Zhipeng Ren</a>, <a href="https://publications.waset.org/abstracts/search?q=Chen%20Yang"> Chen Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiahui%20Gan"> Jiahui Gan</a>, <a href="https://publications.waset.org/abstracts/search?q=Lu%20Feng"> Lu Feng</a>, <a href="https://publications.waset.org/abstracts/search?q=Haibo%20Tong"> Haibo Tong</a>, <a href="https://publications.waset.org/abstracts/search?q=Xuemei%20Xiao"> Xuemei Xiao</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuying%20Chen"> Yuying Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The research of Beidou-3 satellite navigation is on the rise, but in actual work, it is inevitable that satellite data is insecure, research and development is inefficient, and there is no ability to deal with failures in advance. Digital twin technology has obvious advantages in the simulation of life cycle models of aerospace satellite navigation products. In order to meet the increasing demand, this paper builds a Beidou-3 satellite navigation digital twin platform (BDSDTP). The basic establishment of BDSDTP was completed by establishing a digital twin double, Beidou-3 comprehensive digital twin design, predictive maintenance (PdM) mathematical model, and visual interaction design. Finally, this paper provides a time application case of the platform, which provides a reference for the application of BDSDTP in various fields of navigation and provides obvious help for extending the full cycle life of Beidou-3 satellite navigation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BDS-3" title="BDS-3">BDS-3</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20twin" title=" digital twin"> digital twin</a>, <a href="https://publications.waset.org/abstracts/search?q=visualization" title=" visualization"> visualization</a>, <a href="https://publications.waset.org/abstracts/search?q=PdM" title=" PdM"> PdM</a> </p> <a href="https://publications.waset.org/abstracts/167908/digital-twin-platform-for-bds-3-satellite-navigation-using-digital-twin-intelligent-visualization-technology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167908.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">142</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3521</span> Method for Evaluating the Monetary Value of a Customized Version of the Digital Twin for the Additive Manufacturing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fabio%20Oettl">Fabio Oettl</a>, <a href="https://publications.waset.org/abstracts/search?q=Sebastian%20Hoerbrand"> Sebastian Hoerbrand</a>, <a href="https://publications.waset.org/abstracts/search?q=Tobias%20Wittmeir"> Tobias Wittmeir</a>, <a href="https://publications.waset.org/abstracts/search?q=Johannes%20Schilp"> Johannes Schilp</a> </p> <p class="card-text"><strong>Abstract:</strong></p> By combining the additive manufacturing (AM)- process with digital concepts, like the digital twin (DT) or the downsized and basing concept of the digital part file (DPF), the competitiveness of additive manufacturing is enhanced and new use cases like decentral production are enabled. But in literature, one can´t find any quantitative approach for valuing the usage of a DT or DPF in AM. Out of this fact, such an approach will be developed within this paper in order to further promote or dissuade the usage of these concepts. The focus is set on the production as an early lifecycle phase, which means that the AM-production process gets analyzed regarding the potential advantages of using DPF in AM. These advantages are transferred to a monetary value with this approach. By calculating the costs of the DPF, an overall monetary value is a result. Thereon a tool, based on a simulation environment is constructed, where the algorithms are transformed into a program. The results of applying this tool show that an overall value of 20,81 € for the DPF can be realized for one special use case. For the future application of the DPF there is the recommendation to integrate especially sustainable information because out of this, a higher value of the DPF can be expected. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=additive%20manufacturing" title="additive manufacturing">additive manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20concept%20costs" title=" digital concept costs"> digital concept costs</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20part%20file" title=" digital part file"> digital part file</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20twin" title=" digital twin"> digital twin</a>, <a href="https://publications.waset.org/abstracts/search?q=monetary%20value%20estimation" title=" monetary value estimation"> monetary value estimation</a> </p> <a href="https://publications.waset.org/abstracts/133143/method-for-evaluating-the-monetary-value-of-a-customized-version-of-the-digital-twin-for-the-additive-manufacturing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133143.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">200</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3520</span> Mathematical Model of a Compound Gear Pump</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hsueh-Cheng%20Yang">Hsueh-Cheng Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The generation and design of compound involute spur gearings can be used in gear pump.

The current injected must be sinusoidal with reduced harmonic distortion. An additional filter is designed to reduce high-order harmonics on the output side. This strategy exhibits the advantages: Simplicity, reduction of harmonics, the size of the line filter, reduction of the memory requirements and power calculation for the control. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=control" title="control">control</a>, <a href="https://publications.waset.org/abstracts/search?q=inverters" title=" inverters"> inverters</a>, <a href="https://publications.waset.org/abstracts/search?q=LCL%20filter" title=" LCL filter"> LCL filter</a>, <a href="https://publications.waset.org/abstracts/search?q=grid-connected%20photovoltaic%20system" title=" grid-connected photovoltaic system"> grid-connected photovoltaic system</a> </p> <a href="https://publications.waset.org/abstracts/73542/optimization-design-of-single-phase-inverter-connected-to-the-grid" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73542.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">325</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3518</span> Digital Storytelling in the ELL Classroom: A Literature Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nicholas%20Jobe">Nicholas Jobe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> English Language Learners (ELLs) often struggle in a classroom setting, too embarrassed at their skill level to write or speak in front of peers and too lacking in confidence to practice. Storytelling is an age-old method of teaching that allows learners to remember important details while listening or sharing a narrative. In the modern world, digital storytelling through the use of technological tools such as podcasts and videos allow students to safely interact with each other to build skills in a fun and engaging way that also works as a confidence booster. Specifically using a constructionist approach to learning, digital storytelling allows ELL students to grow and build new and prior knowledge by creating stories via these technological means.

In preparing generations as future digital citizens and for active socio-economic participation, ICT plays a key role in respecting gender equality. Although several studies over the years have shown that gender plays an important role in digital exclusion, in recent years, many studies with a focus on economically developed or developing countries identify an improvement in these aspects and a gap narrowing. By measuring students' digital competencies level, this paper aims to identify and analyse the existing gender digital inequalities among students. Our analyses are based on a sample of 1526 middle school students residing in rural areas from Republic of Moldova (54.2% girls, mean age 14,00, SD = 1.02). During the online survey they filled in a questionnaire adapted from the (yDSI) ”The Youth Digital Skills Indicator”. The instrument measures the level of five digital competence areas indicated in The European Digital Competence Framework (DigiCom 2.3.). Our results, based on t-test, indicate that depending on gender, there are no statistically significant differences regarding the levels of digital skills in 3 areas: Information navigation and processing; Communication and interaction; Problem solving. However, were identified significant differences in the level of digital skills in the area of ”Digital content creation” [t(1425) = 4.20, p = .000] and ”Safety” [t(1421) = 2.49, p = .000], with higher scores recorded by girls. Our results contradicts the general stereotype regarding the low level of digital competence among girls, in our sample girls scores being on pear with boys and even bigger in knowledge related to digital content creation and online safety skills. Additional investigations related to boys competence on digital safety are necessary as the implication of their low scores on this dimension may suggest boys exposure to digital threats. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20divide" title="digital divide">digital divide</a>, <a href="https://publications.waset.org/abstracts/search?q=education" title=" education"> education</a>, <a href="https://publications.waset.org/abstracts/search?q=gender%20digital%20divide" title=" gender digital divide"> gender digital divide</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20literacy" title=" digital literacy"> digital literacy</a>, <a href="https://publications.waset.org/abstracts/search?q=remote%20learning" title=" remote learning"> remote learning</a> </p> <a href="https://publications.waset.org/abstracts/160853/the-gender-digital-divide-in-education-the-case-of-students-from-rural-area-from-republic-of-moldova" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160853.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">101</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3516</span> Design of IMC-PID Controller Cascaded Filter for Simplified Decoupling Control System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Le%20Linh">Le Linh</a>, <a href="https://publications.waset.org/abstracts/search?q=Truong%20Nguyen%20Luan%20Vu"> Truong Nguyen Luan Vu</a>, <a href="https://publications.waset.org/abstracts/search?q=Le%20Hieu%20Giang"> Le Hieu Giang </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, the IMC-PID controller cascaded filter based on Internal Model Control (IMC) scheme is systematically proposed for the simplified decoupling control system. The simplified decoupling is firstly introduced for multivariable processes by using coefficient matching to obtain a stable, proper, and causal simplified decoupler. Accordingly, transfer functions of decoupled apparent processes can be expressed as a set of <em>n</em> equivalent independent processes and then derived as a ratio of the original open-loop transfer function to the diagonal element of the dynamic relative gain array. The IMC-PID controller in series with filter is then directly employed to enhance the overall performance of the decoupling control system while avoiding difficulties arising from properties inherent to simplified decoupling. Some simulation studies are considered to demonstrate the simplicity and effectiveness of the proposed method. Simulations were conducted by tuning various controllers of the multivariate processes with multiple time delays. The results indicate that the proposed method consistently performs well with fast and well-balanced closed-loop time responses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coefficient%20matching%20method" title="coefficient matching method">coefficient matching method</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20model%20control%20%28IMC%29%20scheme" title=" internal model control (IMC) scheme"> internal model control (IMC) scheme</a>, <a href="https://publications.waset.org/abstracts/search?q=PID%20controller%20cascaded%20filter" title=" PID controller cascaded filter"> PID controller cascaded filter</a>, <a href="https://publications.waset.org/abstracts/search?q=simplified%20decoupler" title=" simplified decoupler"> simplified decoupler</a> </p> <a href="https://publications.waset.org/abstracts/48781/design-of-imc-pid-controller-cascaded-filter-for-simplified-decoupling-control-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48781.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">442</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3515</span> Challenges and Prospects of Digital Economy Development in Georgia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gulnaz%20Erkomaishvili">Gulnaz Erkomaishvili</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: There are some of the biggest technological shifts happening in the modern world.

In this process, libraries that are the center of the information have also become digitized and become accessible from anywhere and at any time in the world by taking on a structure that has no physical boundaries. In this context, some criteria for information obtained from digital libraries have become more important for users. This paper evaluates the user criteria from different perspectives that make a digital library more useful. The Step-Wise Weight Assessment Ratio Analysis-Weighted Aggregated Sum Product Assessment (SWARA-WASPAS) method is used with flexibility and easy calculation steps for the evaluation of digital library criteria. Three different digital libraries are evaluated by information technology experts according to five conflicting main criteria, ‘interface design’, ‘effects on users’, ‘services’, ‘user engagement’ and ‘context’. Finally, alternatives are ranked in descending order. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20library" title="digital library">digital library</a>, <a href="https://publications.waset.org/abstracts/search?q=multi%20criteria%20decision%20making" title=" multi criteria decision making"> multi criteria decision making</a>, <a href="https://publications.waset.org/abstracts/search?q=SWARA-WASPAS%20method" title=" SWARA-WASPAS method"> SWARA-WASPAS method</a> </p> <a href="https://publications.waset.org/abstracts/110650/digital-library-evaluation-by-swara-waspas-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110650.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">151</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3513</span> Transforming Public Administration in the Digital Era: Challenges and Opportunities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Catalina%20Oana%20Dumitrescu">Catalina Oana Dumitrescu</a>, <a href="https://publications.waset.org/abstracts/search?q=Andreea%20L.%20Drugau-constantin"> Andreea L.

This paper explores how new digital technologies – including artificial intelligence, blockchain, big data and e-governance solutions – are reshaping the functioning of public administrations globally. In addition to the obvious opportunities to streamline and optimize processes, digital transformation brings with it major challenges, such as cyber security, personal data protection, resistance to change and the need to develop new skills for employees. The paper aims to provide a discussion platform for public administration experts, policy makers and technology innovators to consider how governments can balance the benefits and risks of digital transformation. Topics such as the reconfiguration of administrative processes, the creation of interoperable government systems, the involvement of citizens in public decisions through digital platforms, and solutions for reducing the digital gap between developed and developing regions will be addressed. In conclusion, the digital transformation of public administration is not only an opportunity for modernization, but also a necessity to respond to the new demands and challenges of contemporary society. This paper will provide new insights into the role of technology in improving the quality of governance and public services. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=public%20administration" title="public administration">public administration</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20ERA" title=" digital ERA"> digital ERA</a>, <a href="https://publications.waset.org/abstracts/search?q=technology" title=" technology"> technology</a>, <a href="https://publications.waset.org/abstracts/search?q=government%20systems" title=" government systems"> government systems</a>, <a href="https://publications.waset.org/abstracts/search?q=global" title=" global"> global</a> </p> <a href="https://publications.waset.org/abstracts/192568/transforming-public-administration-in-the-digital-era-challenges-and-opportunities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192568.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">17</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3512</span> Module Valuations and Quasi-Valuations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shai%20Sarussi">Shai Sarussi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Suppose F is a field with valuation v and valuation domain Oᵥ, and R is an Oᵥ-algebra.

To cope with the possible abrupt change of kinematic state, extension, and observation distribution over an extended object when a target maneuvers, a multiple model technique is represented based on an MB-track-before-detect (TBD) filter supported by SK-sub-random matrix model (RMM) or sub-ellipses framework.

Watermarks are embedded in the low-frequency coefficients, which is less audible. The key idea is dividing the audio signal into small frames, and magnitude of the 6<sup>th</sup> level of DWT approximation coefficients is modifying based upon the Direct Sequence Spread Spectrum (DSSS) technique. Also, the psychoacoustic model for enhancing in imperceptibility, as well as Savitsky-Golay filter for increasing accuracy in extraction, is used. The experimental results illustrate high robustness against most common attacks, i.e. Gaussian noise addition, Low pass filter, Resampling, Requantizing, MP3 compression, without significant perceptual distortion (ODG is higher than -1). The proposed scheme has about 83 bps data payload. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=audio%20watermarking" title="audio watermarking">audio watermarking</a>, <a href="https://publications.waset.org/abstracts/search?q=spread%20spectrum" title=" spread spectrum"> spread spectrum</a>, <a href="https://publications.waset.org/abstracts/search?q=discrete%20wavelet%20transform" title=" discrete wavelet transform"> discrete wavelet transform</a>, <a href="https://publications.waset.org/abstracts/search?q=psychoacoustic" title=" psychoacoustic"> psychoacoustic</a>, <a href="https://publications.waset.org/abstracts/search?q=Savitsky-Golay%20filter" title=" Savitsky-Golay filter"> Savitsky-Golay filter</a> </p> <a href="https://publications.waset.org/abstracts/86040/robust-and-transparent-spread-spectrum-audio-watermarking" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86040.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">200</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3508</span> Impact of Population Size on Symmetric Travelling Salesman Problem Efficiency</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wafa%27%20Alsharafat">Wafa' Alsharafat</a>, <a href="https://publications.waset.org/abstracts/search?q=Suhila%20Farhan%20Abu-Owida"> Suhila Farhan Abu-Owida </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Genetic algorithm (GA) is a powerful evolutionary searching technique that is used successfully to solve and optimize problems in different research areas. Genetic Algorithm (GA) considered as one of optimization methods used to solve Travel salesman Problem (TSP). The feasibility of GA in finding a TSP solution is dependent on GA operators; encoding method, population size, termination criteria, in general. In specific, crossover and its probability play a significant role in finding possible solutions for Symmetric TSP (STSP). In addition, the crossover should be determined and enhanced in term reaching optimal or at least near optimal. In this paper, we spot the light on using a modified crossover method called modified sequential constructive crossover and its impact on reaching optimal solution. To justify the relevance of a parameter value in solving the TSP, a set comparative analysis conducted on different crossover methods values. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title="genetic algorithm">genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=crossover" title=" crossover"> crossover</a>, <a href="https://publications.waset.org/abstracts/search?q=mutation" title=" mutation"> mutation</a>, <a href="https://publications.waset.org/abstracts/search?q=TSP" title=" TSP"> TSP</a> </p> <a href="https://publications.waset.org/abstracts/81306/impact-of-population-size-on-symmetric-travelling-salesman-problem-efficiency" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81306.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">227</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3507</span> United Nations Sustainable Development Goals and Digital Exclusion: Reconsidering Sustainable Development and Digital Poverty in the Post-Pandemic World</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Serena%20Clark">Serena Clark</a>, <a href="https://publications.waset.org/abstracts/search?q=Katriona%20O%27Sullivan"> Katriona O'Sullivan</a>, <a href="https://publications.waset.org/abstracts/search?q=Kevin%20Marshall"> Kevin Marshall</a>, <a href="https://publications.waset.org/abstracts/search?q=Mac%20MacLachlan"> Mac MacLachlan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper explores the United Nation's sustainable development goals (SDGs) alongside digital poverty and proposes that digital poverty should be a new SDG. The SDGs concentrate on 17 key areas, including economic growth, reducing inequalities, climate action, ending poverty, gender equality, and quality education. Many of the plans to fulfill these goals involve the creation and adaptation of new technologies. As we have seen with COVID-19, access to these technologies has determined communities and societies' ability to respond to these challenges in both developed and developing nations. For example, the transition to online education due to the lockdowns had a detrimental effect on children who did not have access to technology to provide continuity in their educational development. Digitalization and emerging technologies, especially information and communication technologies (ICTs), can help address each goal. Digital poverty and exclusion exacerbate the gap between rich and poor within our societies and internationally, and COVID-19 has further highlighted these issues. Closing this gap can support achieving the SDGs. If access to digital technologies measure society's response and resilience in addressing the challenges the SDGs seek to resolve, should reducing digital poverty be an SDG of its own? This paper will explore this question, arguing that digital poverty should be an independent SDG working alongside and supporting the achievement of the other 17 SDGs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20poverty" title="digital poverty">digital poverty</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20exclusion" title=" digital exclusion"> digital exclusion</a>, <a href="https://publications.waset.org/abstracts/search?q=United%20Nations%20sustainable%20development%20goals" title=" United Nations sustainable development goals"> United Nations sustainable development goals</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20and%20communication%20technologies" title=" information and communication technologies"> information and communication technologies</a> </p> <a href="https://publications.waset.org/abstracts/135812/united-nations-sustainable-development-goals-and-digital-exclusion-reconsidering-sustainable-development-and-digital-poverty-in-the-post-pandemic-world" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135812.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">139</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3506</span> Multiple-Channel Piezoelectric Actuated Tunable Optical Filter for WDM Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hailu%20Dessalegn">Hailu Dessalegn</a>, <a href="https://publications.waset.org/abstracts/search?q=T.%20Srinivas"> T. Srinivas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We propose new multiple-channel piezoelectric (PZT) actuated tunable optical filter based on racetrack multi-ring resonators for wavelength de-multiplexing network applications. We design tunable eight-channel wavelength de-multiplexer consisting of eight cascaded PZT actuated tunable multi-ring resonator filter with a channel spacing of 1.6 nm. The filter for each channel is basically structured on a suspended beam, sandwiched with piezoelectric material and built in integrated ring resonators which are placed on the middle of the beam to gain uniform stress and linearly varying longitudinal strain. A reference single mode serially coupled multi stage racetrack ring resonator with the same radii and coupling length is designed with a line width of 0.8974 nm with a flat top pass band at 1dB of 0.5205 nm and free spectral range of about 14.9 nm. In each channel, a small change in the perimeter of the rings is introduced to establish the shift in resonance wavelength as per the defined channel spacing. As a result, when a DC voltage is applied, the beams will elongate, which involves mechanical deformation of the ring resonators that induces a stress and a strain, which brings a change in refractive index and perimeter of the rings leading to change in the output spectrum shift providing the tunability of central wavelength in each channel. Simultaneous wave length shift as high as 45.54 pm/V has been achieved with negligible tunability variation in the eight channel tunable optical filter proportional to the DC voltage applied in the structure, and it is capable of tuning up to 3.45 nm in each channel with a maximum loss difference of 0.22 dB in the tuning range and out of band rejection ratio of 35 dB, with a low channel crosstalk ≤ 30 dB. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=optical%20MEMS" title="optical MEMS">optical MEMS</a>, <a href="https://publications.waset.org/abstracts/search?q=piezoelectric%20%28PZT%29%20actuation" title=" piezoelectric (PZT) actuation"> piezoelectric (PZT) actuation</a>, <a href="https://publications.waset.org/abstracts/search?q=tunable%20optical%20filter" title=" tunable optical filter"> tunable optical filter</a>, <a href="https://publications.waset.org/abstracts/search?q=wavelength%20de-multiplexer" title=" wavelength de-multiplexer"> wavelength de-multiplexer</a> </p> <a href="https://publications.waset.org/abstracts/24287/multiple-channel-piezoelectric-actuated-tunable-optical-filter-for-wdm-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24287.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">437</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3505</span> Optimization of the Dental Direct Digital Imaging by Applying the Self-Recognition Technology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mina%20Dabirinezhad">Mina Dabirinezhad</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohsen%20Bayat%20Pour"> Mohsen Bayat Pour</a>, <a href="https://publications.waset.org/abstracts/search?q=Amin%20Dabirinejad"> Amin Dabirinejad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper is intended to introduce the technology to solve some of the deficiencies of the direct digital radiology. Nowadays, digital radiology is the latest progression in dental imaging, which has become an essential part of dentistry. There are two main parts of the direct digital radiology comprised of an intraoral X-ray machine and a sensor (digital image receptor). The dentists and the dental nurses experience afflictions during the taking image process by the direct digital X-ray machine. For instance, sometimes they need to readjust the sensor in the mouth of the patient to take the X-ray image again due to the low quality of that. Another problem is, the position of the sensor may move in the mouth of the patient and it triggers off an inappropriate image for the dentists. It means that it is a time-consuming process for dentists or dental nurses. On the other hand, taking several the X-ray images brings some problems for the patient such as being harmful to their health and feeling pain in their mouth due to the pressure of the sensor to the jaw. The author provides a technology to solve the above-mentioned issues that is called “Self-Recognition Direct Digital Radiology” (SDDR). This technology is based on the principle that the intraoral X-ray machine is capable to diagnose the location of the sensor in the mouth of the patient automatically. In addition, to solve the aforementioned problems, SDDR technology brings out fewer environmental impacts in comparison to the previous version. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dental%20direct%20digital%20imaging" title="Dental direct digital imaging">Dental direct digital imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20image%20receptor" title=" digital image receptor"> digital image receptor</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20x-ray%20machine" title=" digital x-ray machine"> digital x-ray machine</a>, <a href="https://publications.waset.org/abstracts/search?q=and%20environmental%20impacts" title=" and environmental impacts"> and environmental impacts</a> </p> <a href="https://publications.waset.org/abstracts/126748/optimization-of-the-dental-direct-digital-imaging-by-applying-the-self-recognition-technology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/126748.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">138</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3504</span> Modelling Medieval Vaults: Digital Simulation of the North Transept Vault of St Mary, Nantwich, England</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Webb">N.

Digital surveying tools are used to document the architecture, followed by an analysis process to hypothesise and simulate possible design solutions, had the vault been completed. A number of options, both two-dimensionally and three-dimensionally, are discussed based on comparison with examples of other contemporary vaults, thus adding another specimen to the corpus of vault designs.

Digital age students learn differently than their teachers did, so now the teacher should be constantly evolving their methods and teaching techniques to be more in touch with the student. In this paper a case study presents how were used some of these technologies by accompanying a classroom course, this in order to provide students with a different and innovative experience as their teacher usually presented the activities to develop. As students worked in the various activities, they increased their digital skills by employing unknown tools that helped them in their professional training. The twenty-first century teacher should consider the use of Information and Communication Technologies in the classroom thinking in skills that students of the digital age should possess. It also takes a brief look at the history of distance education and it is also highlighted the importance of integrating technology as part of the student's training. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20tools" title="digital tools">digital tools</a>, <a href="https://publications.waset.org/abstracts/search?q=on-line%20learning" title=" on-line learning"> on-line learning</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20networks" title=" social networks"> social networks</a>, <a href="https://publications.waset.org/abstracts/search?q=technology" title=" technology"> technology</a> </p> <a href="https://publications.waset.org/abstracts/17565/application-of-digital-tools-for-improving-learning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17565.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">403</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3502</span> Performance Analysis of Shunt Active Power Filter for Various Reference Current Generation Techniques</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vishal%20V.%20Choudhari">Vishal V.

Indeed, recent studies explored the implication of technology use in their leisure and learning activities. Educators face an essential need to utilize technology and implement them into the curriculum. To do that, educators need to understand how young people use digital technology. This study aims to explore K12 students' digital lives from their point of view, to reveal their digital activities, age and gender differences with respect to digital activities, and to present the students' attitudes towards technologies in learning. The study approach is quantitative and includes354 students ages 6-16 from three schools in Israel. The online questionnaire was based on self-reports and consists of four parts: Digital activities: leisure time activities (such as social networks, gaming types), search activities (information types and platforms), and digital application use (e.g., calendar, notes); Digital skills (requisite digital platform skills such as evaluation and creativity); Social and emotional aspects of digital use (conducting digital activities alone and with friends, feelings, and emotions during digital use such as happiness, bullying); Digital attitudes towards digital integration in learning. An academic ethics board approved the study. The main findings reveal the most popular K12digital activities: Navigating social network sites, watching TV, playing mobile games, seeking information on the internet, and playing computer games. In addition, the findings reveal age differences in digital activities, such as significant differences in the use of social network sites. Moreover, the finding raises gender differences as girls use more social network sites and boys use more digital games, which are characterized by high complexity and challenges. Additionally, we found positive attitudes towards technology integration in school. Students perceive technology as enhancing creativity, promoting active learning, encouraging self-learning, and helping students with learning difficulties. The presentation will provide an up-to-date, accurate picture of the use of various digital technologies by k12 students. In addition, it will discuss the learning potentials of such use and how to implement digital technologies in the curriculum.

The algorithm simulated the process of bee foraging and optimization and made the high likelihood region of the backward probability of particles moving to improve the rationality of particle distribution. The opposition-based learning (OBL) strategy is introduced to optimize the initial population of the artificial bee colony algorithm. The convergence factor is introduced into the neighborhood search strategy to limit the search range and improve the convergence speed. Finally, the crossover and mutation operations of the genetic algorithm are introduced into the search mechanism of the following bee, which makes the algorithm jump out of the local extreme value quickly and continue to search the global extreme value to improve its optimization ability. The simulation results show that the improved method can improve the estimation accuracy of particle filters, ensure the diversity of particles, and improve the rationality of particle distribution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=particle%20filter" title="particle filter">particle filter</a>, <a href="https://publications.waset.org/abstracts/search?q=impoverishment" title=" impoverishment"> impoverishment</a>, <a href="https://publications.waset.org/abstracts/search?q=state%20estimation" title=" state estimation"> state estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20bee%20colony%20algorithm" title=" artificial bee colony algorithm"> artificial bee colony algorithm</a> </p> <a href="https://publications.waset.org/abstracts/174985/particle-filter-state-estimation-algorithm-based-on-improved-artificial-bee-colony-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174985.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">151</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3498</span> Advancing Communication Theory in the Age of Digital Technology: Bridging the Gap Between Traditional Models and Emerging Platforms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sidique%20Fofanah">Sidique Fofanah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper explores the intersection of traditional communication theories and modern digital technologies, analyzing how established models adapt to contemporary communication platforms. It examines the evolving nature of interpersonal, group, and mass communication within digital environments, emphasizing the role of social media, AI-driven communication tools, and virtual reality in reshaping communication paradigms. The paper also discusses the implications for future research and practice in communication studies, proposing an integrated framework that accommodates both classical and emerging theories. <p
