The study examined the solution of nonlinear oscillator and thermal properties of interacting system of real polyatomic molecules. A nonlinear oscillator potential was substituted into the radial part of the Schrodinger wave equation and solved using the Frobenius method to obtain the energy eigenvalues of the system. The partition function and the energy eigenvalues are used to determine three thermal properties for four polyatomic molecules which showed that added energy is required in the absence of the nonlinear term as the orbital and magnetic quantum numbers are increased and degeneracy completely removed. Other findings also reveal that as the virial coefficients of the four polyatomic molecules vary, the additive property of entropy is observed as well as the enhancement of the mean energy approximately proportional to the volume of the molecules. The four polyatomic molecules under consideration are environmentally impactful and are indispensable to man.
该研究考察了非线性振荡器的求解和实际多原子分子相互作用系统的热特性。将非线性振荡器势代入薛定谔波方程的径向部分,并使用弗罗贝尼斯法求解,从而得到系统的能量特征值。利用分割函数和能量特征值确定了四种多原子分子的三种热特性,结果表明,随着轨道量子数和磁量子数的增加以及退化现象的完全消除,在没有非线性项的情况下需要增加能量。其他研究结果还表明,随着四种多原子分子的维拉系数的变化,熵的可加性以及与分子体积近似成正比的平均能量的增强也被观察到。所研究的四种多原子分子对环境有影响,是人类不可或缺的物质。

Khalil Al Ahmad, Farah Aini Abdullah
In many paper, Multi-stage Differential Transform Method (MsDTM) has been presented as a method to solve linear and nonlinear equations of various kinds. Multi-stage Differential Transform method has been used to find the exact or analytical approximate solution of the different problems. But only a few works have been considered of convergence of this method. In this paper, Convergence analysis of multi-stage differential transform method is presented. Some numerical examples are proposed to verify the convergence of the proposed method
在许多论文中,多级微分变换法(MsDTM)被作为一种求解各种线性和非线性方程的方法而提出。多级微分变换法被用来寻找不同问题的精确解或分析性近似解。但只有少数著作考虑了这种方法的收敛性。本文介绍了多级微分变换方法的收敛性分析。提出了一些数值示例来验证所提方法的收敛性

On the Compactness of Lie Elements 论列元素的紧凑性
Pub Date : 2024-02-29 DOI: 10.47363/jpma/2024(2)108
T. Konstantopoulos
Let us suppose we are given a composite homeomorphism J. Recent interest in maximal functors has centered on computing sets. We show that Y is not equal to Λ. It has long been known that there exists a solvable and co-abelian pseudo-essentially algebraic, M¨obius polytope acting semi-canonically on an integral, Borel scalar [20]. Here, structure is clearly a concern.
让我们假设有一个复合同构 J,最近人们对最大函数的兴趣主要集中在计算集上。我们将证明 Y 不等于Λ。人们早已知道,存在一个可解的、共标注的伪本质代数 M¨obius 多面体,它半规范地作用于一个积分波尔标量[20]。在这里,结构显然是一个值得关注的问题。

The article is dedicated to the theoretical study of the non-stationary Combustion Velocity of Solid Rocket Fuel (CVSRF). To calculate the Internal Ballistic Characteristics (IBC) of solid fuel missile engines, combustion velocity laws are used. These laws represent stationary relationships between the Combustion Velocity of Solid Rocket Fuel (CVSRF) and initial pressure and temperature. These relationships are experimentally determined under “stationary” conditions, i.e., by burning fuel samples in stationary conditions.
本文致力于固体火箭燃料非稳态燃烧速度(CVSRF)的理论研究。要计算固体燃料导弹发动机的内部弹道特性(IBC),需要使用燃烧速度定律。这些定律代表了固体火箭燃料燃烧速度(CVSRF)与初始压力和温度之间的静态关系。这些关系是在 "静止 "条件下通过实验确定的,即在静止条件下燃烧燃料样品。

In examining the area of a square within the area of a circle whose diagonal line bisects the square into two equal halves of the right triangles; is the diameter of that circle’s area in consideration. Clearly, transformation of a circle determines the ratio of expansion- in relation to its radius given that it is increasing by half. Thus, as the difference of the areas of the relative circles is half of pi; then subtracting the larger area of a circle from its larger relative square which is within its circumference: with that of the smaller area of a circle whose smaller square is also within its radius- results into half of pi minus half. Where then it is easier from such, to deduce the Archimedes constant.while the GDP is projected to increase from $603 billion in 2020 to $15 trillion in 2063. The military spending is projected to increase from $2.6 billion to $33.94 billion, and the trade balance is projected to increase from $15 billion in 2020 to $29.99 billion in 2063. The study concludes that the projected indicators align with the 2063 Africa Agenda and recommends policies that would foster sustainable economic growth and development in Nigeria. By understanding the trends and patterns of these socioeconomic indicators, policymakers can make informed decisions about how to allocate resources and promote sustainable development in Nigeria and beyond
在圆的面积内检查一个正方形的面积,它的对角线将正方形平分成两个相等的直角三角形;是圆的面积的直径。很明显,圆的变换决定了它的膨胀率——相对于它的半径,它增加了一半。因此,相对圆的面积之差是圆周率的一半;然后用圆周内相对较大的正方形减去圆的较大面积,再用半径内相对较小的正方形减去圆的较小面积,得到PI - 1 / 2的一半。这样就更容易推导出阿基米德常数了。而GDP预计将从2020年的6030亿美元增加到2063年的15万亿美元。军费开支预计将从26亿美元增加到339.4亿美元,贸易差额预计将从2020年的150亿美元增加到2063年的299.9亿美元。该研究的结论是,预测的指标与《2063年非洲议程》一致,并提出了促进尼日利亚可持续经济增长和发展的政策建议。通过了解这些社会经济指标的趋势和模式,决策者可以就如何分配资源和促进尼日利亚及其他地区的可持续发展做出明智的决定

The Data from the Lunar Laser Ranging Project Contradict Einstein’s Genius Spacetime Idea 月球激光测距计划的数据与爱因斯坦的天才时空理论相矛盾

What happens to a laser beam that points from the bottom of a train (at rest) to a point in the ceiling when the train is moving very fast. Will the beam still hit this point, or will it hit the ceiling behind this point? In the years around 1900 scientists were convinced that photons get a lateral momentum in the direction of movement, because they are particles. But R. Feynman concluded that a mirror emits new photons and is therefore a light source and together with Einstein’s second STR-postulate the laser beam should hit the ceiling behind this point. This can be tested with the return rates of photons from a mirror on the Moon. The results show clearly with an error of probability < 10-80 that photons do not get a lateral momentum but arrive at that location where the Earth was 2.55 seconds before. Besides the detection of an additional velocity of Earth in the Universe this article proves that Einstein’s geometric spacetime idea is wrong because the physical basis for that is wrong
当火车高速行驶时,从静止的火车底部指向车顶某一点的激光束会发生什么?梁还是会碰到这个点,还是会碰到这个点后面的天花板?在1900年左右,科学家们确信光子在运动方向上有横向动量,因为它们是粒子。但R. Feynman得出结论,镜子会发射新的光子,因此是光源,再加上爱因斯坦的第二个str假设,激光束应该在这一点后面击中天花板。这可以用月球上镜子反射的光子的返回率来测试。结果清楚地表明,光子没有得到横向动量,而是到达了2.55秒前地球所在的位置,误差概率< 10-80。除了探测到宇宙中地球的额外速度外,这篇文章还证明了爱因斯坦的几何时空思想是错误的,因为它的物理基础是错误的
