Литий-күкірт (Li-S) батареялары жоғары теориялық энергия тығыздығы мен үнемділігіне байланысты үлкен назар аудартады. Дегенмен, циклдің нашар қызмет ету мерзімі және төмен өткізгіштік сияқты қиындықтар олардың практикалық қолданылуына кедергі келтіреді. Бұл зерттеу биомассадан алынған көміртегі мен никель оксидінің композициясынан жасалған жаңа күкірт катод материалы және сепаратор модификаторын дамыту арқылы Li-S батареяларының өнімділігін жақсартуға бағытталған. Олардың құрылымдық және электрохимиялық қасиеттерін бағалау үшін КҚГ, КҚГ@S, КҚГ-NiO@S және КҚГ-NiO композиттерінің синтезі және сипаттамасы жүргізілді. Электрохимиялық сынақтар КҚГ-NiO@S катодының модификацияланған КҚГ-NiO сепараторымен біріккен кезде, модификацияланбаған сепараторы бар GPC@S катодымен салыстырғанда, жоғары өнімділікті қуатты сақтауды, тұрақтылықты және жақсартылған кулондық тиімділікті көрсетті. Зерттеу жұмысында жоғары арнайы беттік ауданы бар графен тәрізді кеуекті көміртегі биоқалдық күріш қауызынан көміртектендіру және термохимиялық белсендіру процестері арқылы тиімді синтезделді. Күріш қауызынан синтезделген графен тәрізді кеуекті көміртегі мен никель оксиді бар композит кеуектеріне күкіртті орналастыру балқыту-диффузия әдісі арқылы жүзеге асырылды. Дайындалған катодты материал КҚГ-NiO@S композиті құрамындағы күкірттің мөлшері 60 %-ға жуық екені термогравиметриялық әдіс TGA арқылы расталды. КҚГ-NiO@S композитінен және КҚГ-NiO сепараторынан жасалған катодты материал бастапқыда 1599±20 мАсағг-1 разрядтық сыйымдылыққа қол жеткізіп, 0,2 C-де,100 циклден кейін 790,29±10 мАсағг-1 сыйымдылықты сақтап қалды.

Simulation Study on Truck Noise and Distance Minimization with the Novel Dhouib-Matrix4-PMO Method
Authors: Dhouib Souhail 
Published: December 2024

In transportation, a famous problem known as Travelling Salesman Problem (TSP) is based on optimizing distance (or time, cost, noise, … etc.) between all nodes. In this paper, two criteria are stimulatingly minimized the distance and the noise using the innovative Dhouib-Matrix4-PMO (DM4-PMO) metaheuristic for a truck case study. The DM4-PMO works on two steps and generate two Pareto non dominated solutions. Where, the first Pareto set is generated using a pondered function and the followed second Pareto is created via a logographical optimization. Simulation results, using Python programming language, on a truck case study (with the noise and the distance minimization) prove that the proposed DM4-PMO method can unravel the multi-objective TSP with an ergonomical graphical representation of the Pareto non dominated set solutions. Further research work will focus on the application of DM4-PMO on other complicated problem such as the multi-objective scheduling problem.

Published: December 2024

Aiming at the problem of GNSS signal failure of unmanned ground vehicles in urban environments, a robust integrated navigation system based on IMU/GNSS/ vision/geomagnetic combination is designed, which can generate full-dimension navigation information under the framework of factor graph (FG). Different from the traditional FG model which takes IMU measurement as the core, this paper designs a complete navigation information fusion algorithm and covariance matrix based on visual odometry. To improve the accuracy and reliability of navigation information, this paper introduces offline maps. Given the different dimensions measured in the process of attitude information optimization and the particularity of the rotation matrix, this paper designed an attitude update process based on visual feature points to realize the fusion of IMU, geomagnetic, and feature points. Long endurance road test in a typical urban environment shows that the horizontal positioning accuracy is 4.38m (RMSE), and course accuracy is 0.849° (RMSE).
Routing through networks with hierarchical topology aggregation

Published: December 2024

In the future, global networks will consist of a hierarchy of subnetworks called domains. For reasons of both scalability and security, domains will not reveal details of their internal structure to outside nodes. Instead, these domains will advertise only a summary, or aggregated view, of their internal structure, e.g., as proposed by the ATM PNNI standard. This work compares, by simulation, the performance of several different aggregation schemes in terms of network throughput (the fraction of attempted connections that are realized), and network control load (the average number of crankbacks per realized connection). The simulation emulate a connection oriented network with a PNNI‐like hierarchical source routing algorithm. Our main results are: (1) minimum spanning tree is a good aggregation scheme; (2) exponential link cost functions perform better than min‐hop routing; (3) our suggested logarithmic update scheme that determine when re‐aggregation should be computed can significantly reduce the computational overhead due to re‐aggregation with a negligible decrease in performance.
On cost‐based routing in connection‐oriented high‐speed networks
Authors: Ke Kai‐Wei , Lea Chin‐Tau 
Published: December 2024

Not only does cost‐based routing achieve a higher throughput, it also removes the instability problem inherent in fixed‐path routing networks with alternate paths. In the paper we evaluate the performance of two cost‐based routing schemes: one centralized and one distributed. The latter has a much lower complexity than the former. Although the distributed version does not always use the least‐cost path, our results indicate the performance of both schemes are about the same. We also compare them with least‐loaded routing to demonstrate the ability of cost‐based routing to stabilize the network performance even under an over‐loaded condition. But to make cost‐based routing a viable option for a high‐speed network, we must find a way to compute the cost function. Recently a theory based on the concept of quantization was developed. It can significantly reduce the complexity of cost computation. With this problem solved, cost‐based routing becomes a serious contending routing algorithm for a high‐speed multirate network. The results in the paper demonstrate that the performance degradation caused by quantizing the cost function is insignificant.

Published: December 2024

With the rapid growth of the Internet into a global communication and commercial infrastructure, the need for Quality of Services (QoS) in the Internet becomes more and more important. With a Bandwidth Broker (BB) support in each administrative domain Differentiated Services (DiffServ) is seen as a key technology for achieving QoS guarantees in a scalable, efficient, and deployable manner in the Internet. This paper presents the design and implementation of a new Bandwidth Broker (BB) model to achieve QoS across a DiffServ domain. Our BB uses centralized network state maintenance and pipe-based intra-domain resource management schemes. The proposed model significantly reduces admission control time and minimizes scalability problems present in prior research while optimizing network resource utilization. The experimental results verify the achievements of our model.

Authors: Fadhiela ND Keumala , Siringo ringo Liston 
Published: December 2024

The agriculture sector highly depends on various suppliers to meet its input requirements. Because the agriculture sector relies so heavily on its suppliers, robust supply chain management and strong supplier relationships ensure agribusiness sustainability and efficiency. Aceh's coffee supply chain is typified by low profitability and poor optimization, especially regarding Gayo Arabica coffee. The COVID-19 pandemic has elevated distribution risks at different supply chain stages, exacerbating this further. The relationship between supply chain innovation and competitive advantage in the coffee sector in Aceh Tengah District, Indonesia, is investigated in this quantitative study employing a mediation model. With 60 respondents, Central Aceh Regency was selected using a purposive sampling technique for research purposes. This study uses a Likert-scale questionnaire with structural equation modeling (PLS-SEM). This research aims to assist Acehnese coffee companies in gaining a competitive edge through innovative supply chain practices, resulting in more robust and efficient risk management and sustainability strategies. The results show that supply chain innovation and resilience capability do not affect competitive advantage, where the p-value of these two variables is 0,4. In addition, resilience capability as a mediating variable does not directly affect supply chain innovation and competitive advantage.
