Nonlinear network creates complex homotopy structural communication in wireless network medium because of complex distribution approach. Due to this multicast topological connection structure, the queuing probability was non regular principles to create routing structures. To resolve this problem, we propose a Co-cluster homotopy queuing model (Co-CHQT) for Nonlinear Algebraic Topological Structure (NLTS-) for improving poison distribution network communication. Initially this collects the routing propagation based on Nonlinear Distance Theory (NLDT) to estimate the nearest neighbor network nodes undernon linear at x_(a,b)→ax²+bx² = c. Then Quillen Network Decomposition Theorem (QNDT) was applied to sustain the non-regular routing propagation to create cluster path. Each cluster be form with co variance structure based on Two unicast 2(n+1)-Z2(n+1)-Z network. Based on the poison distribution theory X_(a,b) ≠ µ(C), at number of distribution routing strategies weights are estimated based on node response rate. Deriving shorte;'l/st path from behavioral of the node response, Hilbert -Krylov subspace clustering estimates the Cluster Head (CH) to the routing head. This solves the approximation routing strategy from the nonlinear communication depending on Max- equivalence theory (Max-T). This proposed system improves communication to construction topological cluster based on optimized level to produce better performance in distance theory, throughput latency in non-variation delay tolerant.

This paper aims to reexamine Homorganic Cluster Lengthening in Late Old English whereby OE short vowels became lengthened before specific consonant clusters such as /-ld, -nd, -mb, -rd, -rð, -ng, -rz/. As for the motivation for this apparently odd-looking sound change, I propose that it was the result of phonologization of the phonetic lengthening of syllables containing resonants homorganic with a following voiced obstruent. Adopting Luick's (1898) view of "resonant+voiced homorganic obstruent" phonologically as a single coda, I show that Homorganic Cluster Lengthening is in fact a natural sound change that can be explained with the proper postulation of a few quantity-related universal constraints within the framework of the Optimality Theory. The fact that the constraints and their ranking as posited in this paper can also account for Pre-Cluster Shortening points to the validity of my approach in the analysis of other quantity changes in Middle English.

By using Density Functional Theory (DFT), we have performed alkali metal and alkaline earth metal inside fullerene-like BeO cluster (FLBeOC) in terms of energetic, geometric, charge transfer, work function and electronic properties. It has been found that encapsulated processes of the alkali metal are exothermic and thermodynamically more favorable than alkaline earth metal encapsulation, so that interaction energy ($E_{int}$) of the alkali metal encapsulation FLBeOC is in the range of -0.02 to -1.15 eV at level of theory. It is found that, the electronic properties of the pristine fullerene-like BeO cluster are much more sensitive to the alkali metal encapsulation in comparison to alkaline earth metal encapsulation. The alkali and alkaline earth metal encapsulated fullerene-like BeO cluster systems exhibit good sensitivity, promising electronic properties which may be useful for a wide variety of next-generation nano-sensor device components. The encapsulation of alkali and alkali earth metal may increase the electron emission current from the FLBeOC surface by reducing of the work function.

Welwyn Garden City benefits from the greater design cohesion and management of development which gave it a more distinctive 'brand image' almost from the outset than its older garden city(Letchworth, Hampstead). Its planner, Louis de Soissons, brought a more obvious sense of traditional formal urbanism to the design of the second garden city. This was rather different to the distinctive but rather more informal arts and crafts approach of Raymond Unwin. Here it attempts to analyze how they greatly and firmly established the concept of Housing Group in the residential design, and what similar elements between Unwin and de Soissons in the New Town planning. It is pointed out that the Housing Group theory is composed of recognizing urban life as totality, and group planning theory, and that they definitely originated a new technique in the residential area. It is analyzed that the syntactic relations between the group planning theory and enclosed housing cluster designs in the English garden city are epitomized in Welwyn Garden City.

탄성체 (가교된 고분자) 가스가 용해된 고분자 또는 유기 용매에 용해된 고분자 용액에서 기포 생성을 예측하기 위하여 균일한 기포 생성은 고전적인 이론에서의 임계 기포의 생성이 아닌 임계 뭉치의 생성을 통하여 이루어진다는 분자 뭉치 이론을 적용하였다. 또한 탄성체나 고분자 내에서 기포가 생성하는 경우 임계 기포가 극복해야 할 탄성 에너지를 고려하였다. 대략 $10^{8}$∼$10^{12}$개에 달하는 분자 뭉치 이론에 의해 계산된 단위 부피당 생성된 기포 수는 실험치와 잘 일치하였다.

클러스터링 프로토콜의 클러스터 간 주파수 간섭에서 클러스터 멤버는 자신의 전송률을 유지 또는 증가시키기 위해 많은 양의 에너지를 소비하여 노드 수명이 급격히 감소하는 문제가 있다. 이에 서로 다른 주파수를 사용하는 FDM 기반의 자원할당 정책이 요구된다. 본 논문에서는 클러스터 간 주파수 간섭 문제를 해결하기 위해 게임의 참여자간 자원협상문제를 다루는 게임이론을 사용하여 클러스터 간 합리적인 파워 전략을 제시하였다. 특히 각 클러스터가 이기적으로 주파수 자원을 점유하려는 경우를 가정한 비협조게임과 협상을 통해 주파수를 나누어 사용하는 협조게임의 관점에서 각각 분석하였다. 또한 시뮬레이션을 사용하여 협조게임과 비협조게임에서의 노드의 수명시간을 비교하였다.

To quantitatively assess the correlation between subsystems within a port cluster and the overall coordinated development of the port group, the current paper evaluates the coordinated development of port clusters. First, we construct an evaluation index system for the coupling and coordination of port clusters. Next, we introduce the contribution index of port subsystems, coupling degree, and coupling coordination degree functions to formulate a coupling coordination evaluation model for the port cluster. Finally, we use the Yangtze River Delta port cluster as a case study for validation, specifically using empirical data from 2012 to 2021. The findings reveal distinct phased characteristics in the coupling and coordination of port clusters in the Yangtze River Delta, marked by a notable transition from "maladjustment" to "coordination." Further, sustained high coupling values over a decade indicate a significant level of competition and cooperation among ports within the Yangtze River Delta port cluster. Over time, this competitive and collaborative dynamic has progressively evolved toward a more positive and structured direction. Lastly, it is expected that the evaluation model proposed in this paper can be extrapolated to other port clusters to gauge the extent of coordinated development, thereby facilitating horizontal comparisons and vertical analyses.

The ground state of the oxygen molecule is calculated by various methods of coupled cluster approaches and many body perturbation theory using a double zeta plus polarization basis set and the UHF reference state. All the methods employed are capable of describing the oxygen molecule near the equilibrium bond length and the separated atom, but do not correctly depict the breaking of the multiple bond. For this basis set, including more correlations does not necessarily improve the agreement with experiment for molecular properties such as bond lengths and dissociation energies.

In the dynamic cloud computing environment, to ensure, under the terms of service-level agreements, the maximum efficiency of resource utilization, it is necessary to investigate the online dynamic management of virtual machine resources and their operational application systems/components. In this study, the feasibility and properties of the division of virtual machine resources on the cloud platform, using the virtual machine cluster as the management unit, are investigated. First, the definitions of virtual machine clusters are compared, and our own definitions are presented. Then, the feasibility of division using the virtual machine cluster as the management unit is described, and the isomorphism and reconfigurability of the clusters are proven. Lastly, from the perspectives of clustering and cluster segmentation, the dynamics of virtual machines are described and experimentally compared. This study aims to provide novel methods and approaches to the optimization management of virtual machine resources and the optimization configuration of the parameters of virtual machine resources and their application systems/components in large-scale cloud computing environments.
