The suspension coil spring is one of the most important components in a vehicle suspension system. Its primary function is to absorb the vibrational shocks that are occasioned by irregular road surface to provide the vehicle with stability and ride comfort. The main objective of this study is to design a suspension coil spring made of structural steel for light duty vehicles with the aim of weight and cost reduction. This study was motivated by the government of Ghana’s actions to industrialise the automotive sector of the country through government policies and programs. The study made use of high carbon steel and low carbon steel as the control materials and structural steel as the implementing material. This was done to determine the suitability of structural steel for vehicle suspension coil spring. The study analysed parameters such as total deformation, equivalent Von Mises stress, maximum shear stress, and safety factor in the static structural analysis. The fatigue analysis also analysed parameters such as fatigue life and fatigue alternating stress. The results of the study revealed that the suspension spring made of structural steel has superior properties against all the parameters set for this study apart from deformation. The two control materials that are known for suspension coil spring design and manufacture have better properties to withstand deformation than the implementing material.

移动通信系统中一种切换管理的性能研究

移动通信系统中一种切换管理的性能研究

移动通信系统在我们的生活和科学中越来越重要，作为一种重要的系统，它见证了无线通信的飞速发展。当一个移动设备从一个小区移动到另一个的时候，它的呼叫控制也必须从当前的基站转移到新的基站，且不能丢失当前的呼叫。这个过程被称为“越区切换”，即当一个移动设备穿过小区边界时，它的服务也由一个基站转移到另一个基站。越区切换过程会可以通过以下五种模型来标识：相关信号强度(RSS)，带阈值的相关信号强度(RSS-T)，带迟滞的相关信号强度(RSS-H)，带阈值和迟滞的相关信号强度(RSS-HT)，带阈值距离和迟滞的相关信号强度(RSS-TDH)。本文提出一种不仅基于RSS测量方法，而且利用阈值距离和邻居BSS功率边界的越区切换策略，来改进越区管理过程。首先，当移动设备从一个小区移动到另一个时，我们给出一个阈值来判断是否要越区切换。然后，我们也给出了当前接收信号和BS后续接收信号之间的边界条件，必须满足用来传输新的小区内的呼叫。最后，我们给出了一个基站之间应该超出的阈值距离，以保证基站之间越区切换过程可以有序完成。这些阈值的目的是为了减少不必要的可能发生的越区切换，从而减小越区切换的延迟和呼叫丢失。本文通过一些实验仿真结果，验证了这种算法的可行性，包括基于相关信号强度的结果。我们将本文给出的算法与基于绝对和相对信号强度的算法，以及只基于距离的算法进行了比较。仿真结果显示，这种新的算法相比于其他算法有效的提高了越区切换性能，减少了不必要的越区切换。

In this paper, we obtain optimum allocation of replaceable and repairable components in a system design. When repair and replace time are considered as random in the constraints. We convert probabilistic constraint into an equivalent deterministic constraint by using chance constrained programming. We have used the selective maintenance policy to determine how many components to be replaced & repaired within the limited maintenance time interval and cost. A Numerical example is presented to illustrate the computational procedure and problem is solved by using LINGO Software.

In this paper, we consider an allocation problem in multivariate surveys with non-linear costs of enumeration as a problem of non-linear stochastic programming with multiple objective functions. The solution is obtained through Chance Constrained programming. A different formulation of the problem is also presented in which the non-linear cost function is minimised under the precision constraints on estimates of various characters. The solution is then obtained by using Modified E-model. A numerical example is solved for both the formulations.
