This article is not inspired by any religion or quantum many-worlds interpretation. The mathematics of multiverse is presented here. The mass operator was introduced earlier by Alnobani. This operator is used here to deduce the time state. It is found that time has four states and those four states are orthogonal. Time is the constitution of any verse. Time has direction. Every orthogonal direction of time belongs to a verse. Past and future belong to opposite directions of time and they are arbitrary. Other verses are there by their own and not a probabilities of any other verse and if any similarity it is only a coincidence. Among applications of this thesis is travelling through groups of galaxies, or more or less.

To develop an efficient numerical scheme for two-dimensional convection diffusion equation using Crank-Nicholson and ADI, time-dependent nonlinear system is discussed. These schemes are of second order accurate in apace and time solved at each time level. The procedure was combined with Iterative methods to solve non-linear systems. Efficiency and accuracy are studied in term of L2, L∞ norms confirmed by numerical results by choosing two test examples. Numerical results show that proposed alternating direction implicit scheme was very efficient and reliable for solving two dimensional nonlinear convection diffusion equation. The proposed methods can be implemented for solving non-linear problems arising in engineering and physics.

云计算技术的发展使得无论是公有、私有还是混合云计算中心都可以提供良好的性能,因此云计算技术已被不同的运营商广泛地应用。虽然云计算技术对运营商和用户来说都具有优势,但其仍面临维护和管理的挑战,其中一个关键的挑战就是云计算数据中心的能源消耗的效率问题。云计算数据中心要消耗很多能源,但是其中一些能源根本没有用在计算上。云计算数据中心能源效率低的一个主要原因是低效率的资源配置。在云计算环境中有几个因素导致不当的资源分配,使得资源分配仍然是面临的一个问题。因此,必须要研究有效的方法来克服这个问题。在近几年中,虚拟机迁移方法已被作为一种有效的资源利用方法广泛地加以应用,因此对虚拟机(VM)迁移策略和资源分配算法的研究已经成为热点课题。论文重点研究两个主要内容：第一部分是提出一种虚拟机迁移时的VM选择策略,即阈值最大利用率(ThrMaxU)策略。在这一策略中,我们设置了固定的主机利用率的上、下门限,在规定的时间内,我们动态地检查上限和下限是否被超越。当一台主机的利用率低于下限时,在该主机上的所有虚拟机应该迁移出去并关闭该主机。在一些主机的利用率高于上限的情况下,我们就对这些主机按递减顺序排序,以超越上限最多的主机开头,然后选择这些主机中占用CPU使用率比较多的VM进行迁移。我们将提出的这种选择策略与现有的一种分配策略(改进的功率配置降序MBFD策略)结合起来,以评估功耗和性能的折中。我们使用仿真软件CloudSim对我们的研究进行了仿真,并且将所提策略与其他的策略进行了功耗、SLA比例、关闭的主机数和迁移的VM数等几个参数的对比。仿真结果表明,所提出的ThrMaxU策略具有更低的功耗、更少的关闭的主机数和更少的VM迁移数,并且其SLA性能也与其他策略相当。论文第二部分提出了一种改进的最优功率配置(MPBF)算法,可进行全局的资源配置,即在每一次的分配过程中,该算法找到一个这样的服务器,使得一个请求分配到它上面以后,系统增加的功耗最小,因此整个数据中心达到最低的功耗。MPBF算法的基础是所有的服务器具有相同的资源和计算能力,即所有的服务器对用户的请求具有相同的接收、执行和分配资源的能力。我们使用MATLAB对MPBF算法进行了仿真,在不同类型的CPU下,与其他算法进行了功耗、使用的主机数和运行时间等性能的对比。仿真结果表明,所提出的MPBF算法可以获得更低的功耗和更少的主机数,但是其分配用户请求所需的运算时间分别是PBF算法和不使用DVFS算法的2-3倍。

A mathematical model comprising of nonlinear reaction, diffusion, and convection mechanisms seen in natural and anthropogenic processes is numerically investigated here. It is proposed that a higher order numerical scheme of finite difference method be used in conjunction with an iterative approach in order to solve the nonlinear one dimensional convection-diffusion-reaction equation. To account for the wide variety of physical characteristics and boundary conditions, an iterative approach is presented that yields a reliable and precise solution every time. We examined the accuracy and operational efficiency of two distinct finite difference approaches. The efficiency of the system is determined by comparing the estimated results to the appropriate analytical solution by adhering to established norms. Coherence and convergence were analyzed for each approach. The simulation results demonstrate the efficacy and accuracy of these methods in solving nonlinear convection- diffusion-reaction equations. Convection-diffusion-reaction equation modeling is critical for employing the offered results in heat and mass transport processes.

The determination of the impacts of marble mining on the environment in Igarra was carried out via the analysis of soil and water samples as geological medium. Seven soil samples, ten water samples and five rock samples were collected. The samples collected were subjected to petro-graphic and geochemical analysis. The mean concentration of metals in soil from Ekpeshi were Cd (3.254 mg/kg), Co (786.554 mg/kg), Cu (12.911 mg/kg), Ni (18.942 mg/kg), Pb (5.5 mg/kg), and Zn (28.457 mg/kg) while the concentrations of the water samples collected from streams, taps and wells were Cd (0.116 mg/kg), Co (15.225 mg/kg), Cu (0.542 mg/kg), Ni (0.276 mg/kg), Pb (0.486 mg/kg), and Zn (0.742 mg/kg). Lead (Pb) showed high concentration of (0.486 mg/kg), Ni (0.276 mg/kg) and Cd (0.116 mg/kg) as against acceptable limits of 0.01mg/l, 0.02 mg/l (NIS) and 0.07 mg/l (WHO) 0.003 mg/l respectively, while in soil it showed high concentration of Cd (3.254 mg/kg) compared to the acceptable limit of 0.8 mg/kg set by the Dutch Standard limit for soil. Lead, Nickel and Cadmium are found to be in high concentration in both surface and underground water, and this calls for treating water in the study area before it’s used as drinking water via drilling water boreholes by the mining and processing companies operating in the area as a form of corporate social responsibility. Also, the provisions in the mining act should holistically be implemented to safe life and health of the populace of the immediately surroundings.

This study is devoted to the analysis of a one-dimensional time-dependent double-diffusive flow over a semi-infinite vertical plate, under a convective surface boundary condition. Using similarity variable, the governing nonlinear partial differential equations have been transformed into a set of coupled nonlinear ordinary differential equations, which are solved numerically by using shooting method alongside with Runge-Kutta integration scheme as embedded in Maple software programme. The numerical results of the skin-friction coefficient, the Nusselt and Sherwood numbers are discussed and depicted graphically.

Service-Oriented Architecture (SOA) is becoming the dominant approach for developing and organizing distributed enterprise-wide applications. Although the concepts of SOA have been extensively described in the literature and in-dustry, the effects of adopting SOA on software quality are still unclear. The aim of the paper is to analyze how adopt-ing SOA can affect software quality as opposed to the Object-Oriented (OO) paradigm and expose the differential implications of adopting both paradigms on software quality. The paper provides a brief introduction of the architectural differences between the Service-Oriented (SO) and OO paradigms and a description of internal software quality metrics used for the comparison. The effects and differences are exposed by providing a case study architected for both paradigms. The quantitative measure concluded in the paper showed that a software system developed using SOA approach provides higher reusability and lower coupling among software modules, but at the same time higher complexity than those of the OO approach. It was also found that some of the existing OO software quality metrics are inapplicable to SOA software systems. As a consequence, new metrics need to be developed specifically to SOA software systems.

Multiverse Spacetime

A theological train of reasoning is avoided in this paper. The properties of the equal operator presented earlier by Alnobani are given here. A view of the present time is given. As a consequence of the presence of time state, the verses are arranged in couples and every verse including in which we live is a live verse in the same context of human life. This paper interferes with and changes the procedures and philosophy of mathematics itself. Space, mass and time are parts of one whole which is called simply time. The aim of this paper is to make the knowledge of its subject public, so other researchers can contribute to it. The concept of a gate between verses is investigated.

背景:脑卒中是由于大脑相关区域的出血或梗死而突然发生的局灶性神经功能损伤。既往的研究表明,神经损伤引发的肌无力不仅见于四肢的肌肉,也见于呼吸肌,表现为患侧肋间肌、膈肌、腹肌无力,导致呼吸功能异常、呼吸模式改变,减少了肺通气量和呼吸流量,从而增加了呼吸系统并发症的风险。目的:本文使用系统评价与meta分析,目的是收集有关吸气肌训练（inspiratory muscle training,IMT）在改善脑卒中患者呼吸功能、呼吸肌力量与步行能力方面的功效的最新信息。方法:从2010年1月至2021年12月,本文在MEDLINE、EMBASE和Web of Science数据库中进行了在线检索,给出了具有95%置信区间的平均差和风险比。此外,本文使用了Cochrane工具评估偏倚风险。研究选择和数据提取:选取11项随机对照试验（randomized controlled trials,RCTs）,测量脑卒中后患者IMT与非IMT或假IMT的效果。我们提取了有关呼吸肌肉力量、呼吸功能和步行能力的数据。结果:我们的研究纳入了11项RCTs的299名参与者。患者的年龄范围为54至68岁,样本量大小范围为12至51名参与者。脑卒中发病的时间为14天至17.90个月。11篇文献中有5篇涉及急性和亚急性期的脑卒中患者（脑卒中时间少于6个月）,6篇涉及慢性期的脑卒中患者（脑卒中时间长于6个月）。对11篇文献进行的Meta分析显示,IMT对最大吸气压力（maximum inspiratory pressure,MIP）(MD=15.42,95%CI:1.23至29.62,P=0.03)、吸气肌耐力（inspiratory muscle endurance,IME）(MD=18.04,95%CI:10.50至25.58,P<0.00001)、1秒内用力呼气量（forced expired volume in 1 second,FEV）(MD=0.24,95%CI:0.11至0.38,P=0.0005)、用力肺活量（forced vital capacity,FVC）(MD=0.28,95%CI:0.15至0.41,P<0。0001)、呼气峰值流速（peak expiratory flow,PEF）(MD=0.37,95%CI:0.06至0.68,P=0.02)和6分钟步行试验（6-minute walk test,6-MWT）(MD=40.79,95%CI:26.36至55.23,P<0.00001)具有有利影响。对收集到的数据进行亚组分析后发现,对于脑卒中时间少于6个月的患者,吸气肌训练对肺功能FEV、FVC和步行能力（6-MWT）有更好的影响。结论:对于脑卒中时间少于6个月的患者,吸气肌训练干预在改善肺功能参数（FEV、FVC、PEF）、吸气肌力量（MIP、IME）和步行能力等方面具有显著效果。
