Patients find it difficult to imagine how their facial appearance may change after orthodontic treatment without a visual reference. Predicting the postoperative facial appearance may thus be useful for managing expectations, easing communication, and researching different treatment choices. Computer-assisted programs are still relatively expensive and are not portable in comparison to smartphones, and the accuracy of soft tissue profile prediction of these android applications has not been thoroughly assessed. The purpose of the study is to assess how well the Webceph cephalometric Android application predicts changes in soft tissue profile following orthodontic treatment.MATERIALS AND METHOD: A total of 50 patients were screened for eligibility, and 24 young adult patients (8 males, 16 females; mean age 24.8 卤3.9 years) were finally included in the study based on the inclusion and exclusion criteria. The landmarks and parameters of the Legan and Burstone soft tissue analysis were used for the cephalometric analyses. The cephalometric tracings of the actual treatment result and the Webceph predicted treatment outcome was superimposed to calculate the prediction errors. Paired t-test used to compare the statistical differences between the predicted and actual treatment outcomes of the parameters used in the legan and burstone soft tissue analysis.RESULTS: There were significant differences between the predicted and actual values in parameters of legan and burstone soft tissue analysis (P\0.05). It was reported that the prediction in two parameters (i.e., Lower face throat (Sn-Gn-C angle) (Cm-sn-ls) Nasolabial angle) was a significant difference from the actual modifications in class I bimaxillary protrusion group and there were substantial changes in the prediction of two characteristics (facial convexity (G-Sn-Pg angle) and inter labial (Stms-Stmi) in the class II group.CONCLUSIONS: The Webceph VTO prediction in soft tissue changes after the orthodontic treatment in patients with bimaxillary protrusion and class II malocclusion is the most accurate for the nasolabial angle and the least accurate for the mandibular prognathism parameter.</description> <dc:creator>Rushabh Shah</dc:creator> <dc:creator>Sachin Durkar</dc:creator> <dc:creator>Sonali Deshmukh</dc:creator> <dc:creator>Jayesh Rahalkar</dc:creator> <dc:rights> Copyright (c) 2023 EAI Endorsed Transactions on Mobile Communications and Applications https://creativecommons.org/licenses/by/3.0/ </dc:rights> <cc:license rdf:resource="https://creativecommons.org/licenses/by/3.0/" /> <dc:date>2024-07-29</dc:date> <prism:publicationDate>2024-07-29</prism:publicationDate> <prism:volume>8</prism:volume> <prism:doi>10.4108/eetmca.3686</prism:doi> </item> <item rdf:about="https://publications.eai.eu/index.php/mca/article/view/3755"> <title>Improving 6G Network Spectrum Efficiency with Non-Cooperative and Cooperative Spectrum Sharing Using NOMA and Massive-MIMO</title> <link>https://publications.eai.eu/index.php/mca/article/view/3755</link> <description>There is an expectation that standards for sixth-generation (6G) wireless communication networks in the future would give previously unheard-of speeds for the flow of information as well as spectrum optimization. This will present new issues for 6G networks. Non-orthogonal multiple access (NOMA) is one of the most efficient ways to boost the spectrum efficiency (SE) of a 6G network. The most promising contemporary technologies, such as cognitive radio (CR) and multiple access, can be used to improve SE. When NOMA's network-oriented multi-access capabilities are combined with those of the Cognitive Radio Network (CRN), a new era of efficient communication is expected to dawn. To improve the spectral efficiency (SE) of the NOMA DL power domain (PD), this work presents two distinctive strategies that are used in conjunction with un-cooperative and cooperative CRN (Un-CCRN and CCRN) in the event that one primary user (PU) is unable to receive through the dedicated channel due to interference or noise. Users' distances, power placement coefficients, and transmit powers (TPs) vary across the proposed three network topologies, and over the proposed three network sizes of 128x128, 256x256, and 512x512 Massive Multiple Input Multiple Output (M-MIMO). Performance is analyzed while simultaneously considering channel instability and successive interference cancellation (SIC). The channels of fading are modelled after frequency-dependent Rayleigh fading. MATLAB is used to determine the proposed model's SE. With 128x128, 256x256, and 512x512 M-MIMO integrated into the DL NOMA system, the system's SE performance is improved by 73%, 82%, and 87%, respectively; with the Un-CCRN NOMA model, the improvement is 75%, 83%, and 88%; and with the CCRN-NOMA model, the improvement is 75.8%, 84%, and 88.3%. The SE is significantly improved by employing M-MIMO technology. The acquired expressions agree with the outcomes of the provided Monte Carlo simulations, providing further evidence for the validity of our investigation.</description> <dc:creator>Mohamed Hassan</dc:creator> <dc:creator>Manwinder Singh</dc:creator> <dc:creator>Khalid Bilal</dc:creator> <dc:creator>Imadeldin Elsayed</dc:creator> <dc:rights> Copyright (c) 2023 EAI Endorsed Transactions on Mobile Communications and Applications https://creativecommons.org/licenses/by/3.0/ </dc:rights> <cc:license rdf:resource="https://creativecommons.org/licenses/by/3.0/" /> <dc:date>2023-10-23</dc:date> <prism:publicationDate>2023-10-23</prism:publicationDate> <prism:volume>8</prism:volume> <prism:doi>10.4108/eetmca.3755</prism:doi> </item> <item rdf:about="https://publications.eai.eu/index.php/mca/article/view/3888"> <title>Centralized multicasting AODV routing protocol optimized for intermittent cognitive radio ad hoc networks</title> <link>https://publications.eai.eu/index.php/mca/article/view/3888</link> <description>The advancement of wireless technology is affected by Spectrum scarcity and the overcrowding of free spectrum. <a name="_Hlk21069067"></a>Cognitive Radio Ad Hoc Networks (<a name="_Hlk12627331"></a>CRAHNs) have emerged as a possible solution to both the scarcity and overcrowding challenges of the spectrum. The CRAHNs ensure that the Secondary Users (SUs) do co-exist with Primary Users (PUs) in a non-interfering manner. The SUs access the licensed spectrum opportunistically when they are idle. CRAHNs have many use cases which include intermittent networks here referred to as intermittent CRAHNs (ICRAHNs). For example, the Military (MCRAHNs). MCRAHN is complex and characterized by a dynamic topology which is subject to frequent partitioning and route breakages due to attacks and destruction in combat. This study optimizes the routing protocols for intermittent networks such as the MCRAHNs. ICRAHN routing is a challenge due to the network鈥檚 intermittent attribute, which is subject to destruction in the case of MCRAHN which is characterized by frequent link breakages. To better understand the routing in this network scenario, this paper presents two analytic models for the AODV and MAODV protocols based on queuing theory. The analytic models simulate unicast and multicast AODV in terms of factors such as queuing delay, throughput, and network scalability. Numerical analysis shows that MAODV outperforms AODV. Furthermore, the suggested routing protocols' performance was tested using network simulations utilizing the following metrics: throughput, Routing Path delay, Node Relay delay, and Spectrum Mobility delay. The simulation findings suggest that the MAODV protocol outperforms the AODV protocol.</description> <dc:creator>Phetho Phaswana</dc:creator> <dc:creator>Sindiso M Nleya</dc:creator> <dc:creator>Mthulisi Velempini</dc:creator> <dc:rights> Copyright (c) 2023 EAI Endorsed Transactions on Mobile Communications and Applications https://creativecommons.org/licenses/by/3.0/ </dc:rights> <cc:license rdf:resource="https://creativecommons.org/licenses/by/3.0/" /> <dc:date>2024-02-19</dc:date> <prism:publicationDate>2024-02-19</prism:publicationDate> <prism:volume>8</prism:volume> <prism:doi>10.4108/eetmca.3888</prism:doi> </item> <item rdf:about="https://publications.eai.eu/index.php/mca/article/view/5146"> <title>Enhancing Mental Health With PHILOI: A Comprehensive Analysis of Mood Music and Chatbot Module</title> <link>https://publications.eai.eu/index.php/mca/article/view/5146</link> <description>The project aim was to develop an app that would enable the recording and monitoring of behaviour related to specific aspects of wellness, as well as support those aspects of wellness that are entertainment-related. Our main goal was to envision and develop an app with the well-being of users in mind. People鈥檚 moods can be improved upon or changed by music, with music and mental health tightly intertwined. Music is frequently used to complement or change an individual鈥檚 mood. While there are advantages to mood-appropriate music, it may cause us to remain in a depressed, angry, or nervous state. A survey was conducted to examine these aspects. After performing a lot of research and interviews in this area, we found 68% of those surveyed listen to music according to their mood or to change their mood. This inspired us to build an application that not only plays music but also recommends songs to users, eliminating the daily nuisance of selecting the right music, which can waste valuable time. As mental balance is an essential component of healthy existence in today's hectic world, to enhance the practicality of our app, as icing on the cake, we included an AI chatbot that not only converses with the user but also provides them with suitable advice on their concerns.</description> <dc:creator>Kavita Kumavat</dc:creator> <dc:creator>D.

Intelligent Transportation Systems (ITS), and Vehicular Ad Hoc Networks (VANETs) have received significant attention to ensure safety. However, V2V communication in VANETs faces uncontrollable challenges due to frequent intermittent connectivity issues in infrastructure-less networks. Addressing these problems in both safety and non-safety applications is a complex task.OBJECTIVES: To mitigate the intermittent connectivity problems, a novel Sparse Network Computational Model (SNCM) was proposed.METHODS: Extensive simulations using MATLAB to analyze the impact of spatial-temporal variations under different traffic flow densities. We varied the sensitivity factor (位) at different time intervals while maintaining a constant traffic density. RESULTS: The findings indicate that there is no need to increase 位 beyond certain thresholds for each level of service. The simulation results provide valuable guidelines for designing sparse networks, effectively mitigating frequent intermittent disconnections. Simulation experiments revealed an optimal threshold for the sensitivity factor 位 for each level of service. Increasing 位 beyond certain thresholds did not yield significant improvements in mitigating disconnections in V2V communication.CONCLUSION: The results provide valuable insights and guidelines for designing sparse networks to enhance connectivity and address intermittent disconnection issues. This paper presents a groundbreaking endeavor, and therefore, direct comparisons with existing protocols to evaluate its overall performance are beyond the scope of this paper. Instead, the SNCM protocol is intended to set a standard for future researchers to benchmark their research contributions against.</description> <dc:creator>Adams Azameti</dc:creator> <dc:creator>Ferdinand Katsriku</dc:creator> <dc:creator>Ebenezer Owusu</dc:creator> <dc:creator>Jamal-Deen Abdulai</dc:creator> <dc:rights> Copyright (c) 2023 EAI Endorsed Transactions on Mobile Communications and Applications https://creativecommons.org/licenses/by/3.0/ </dc:rights> <cc:license rdf:resource="https://creativecommons.org/licenses/by/3.0/" /> <dc:date>2024-10-08</dc:date> <prism:publicationDate>2024-10-08</prism:publicationDate> <prism:volume>8</prism:volume> <prism:doi>10.4108/eetmca.5536</prism:doi> </item> </rdf:RDF>
