A tree-like substructure on a computer chip whose task it is to carry a signal from a source circuit to possibly many sink circuits and which consists only of wires and so-called repeater circuits is called a repeater tree. We present a mathematical formulation of the optimization problems related to the construction of such repeater trees. Furthermore, we prove theoretical properties of a simp...

For ̄ exible manufacture of a doubly curved sheet metal, a new sheet metal forming process is proposed that uses a movable punch set composed of two pairs of lower support punches and one upper centre punch. The process is characterized by ̄ exibility compared with the existing conventional processes because it does not require any complex-shaped die and the loss of material is minimized by unc...

For the last three decades, a large scale integration of distributed generation (DG) is beginning to change the electrical distribution network from passive to active. Consequently, technical difficulties are created by significant impacts generated by DGs with voltage variation being the dominant effect. This paper presents a comprehensive review of voltage control techniques on electrical dis...

In this paper, we address the question “what is the influence of user search behaviour on the effectiveness of personalized query suggestion?”. We implemented a method for query suggestion that generates candidate follow-up queries from the documents clicked by the user. This is a potentially effective method for query suggestion, but it heavily depends on user behaviour. We set up a series of ...

For the spare parts stocking problem, generally METRIC type methods are used in the context of capital goods. A decision is assumed on which components to discard and which to repair upon failure, and where to perform repairs. In the military world, this decision is taken explicitly using the level of repair analysis (LORA). Since the LORA does not consider the availability of the capital goods...

The silicon substrate has a significant effect on the inductance parameter of a lossy interconnect line on integrated circuit. It is essential to take this into account in determining the transmission line electrical parameters. In this paper, a new quasi-TEM capacitance and inductance analysis of multiconductor multilayer interconnects is successfully demonstrated using finite element method (...

The accurate estimates of values of electromagnetic parameters are essential to determine the final circuit speeds and functionality for designing of highperformance integrated circuits and integrated circuits packaging. In this paper, the quasi-TEM analyses of multilayer coplanar waveguide (CPW) broadside coupled-line balun are successfully demonstrated using Finite Element Method (FEM). We sp...

Optical waveguide is the fundamental element that interconnects the various devices of an optical integrated circuit. In this paper, the propagation characteristics of ridge and buried waveguides have been investigated on light intensity distribution within the structure. The analysis has been done by varying the thickness and also the width of both ridge and buried optical waveguide. The norma...

the aim of this study was to evaluate the effectiveness of an integrated model of emotionally focused approach and gottman model on the quality of marital relationship in married women. in this study the quasi-experimental design with pre-test, post-test and follow up with a control group were used. the study population included married women who went to tehransar health center, district 21. th...
