Efficient quadratic placement for FPGAs.
Field Programmable Gate Arrays (FPGAs) are widely used in industry because they can implement any digital circuit on site simply by specifying programmable logic and their interconnections. However, this rapid prototyping advantage may be adversely affected because of the long compile time, which is dominated by placement and routing. This issue is of great importance, especially as the logic capacities of FPGAs continue to grow. This thesis focuses on the placement phase of FPGA Computer Aided Design (CAD) flow and presents a fast, high quality, wirelength-driven placement algorithm for FPGAs that is based on the quadratic placement approach. In this thesis, multiple iterations of equation solving process together with a linear wirelength reduction technique are introduced. The proposed algorithm efficiently handles the main problems with the quadratic placement algorithm and produces a fast and high quality placement. Experimental results, using twenty benchmark circuits, show that this algorithm can achieve comparable total wirelength and, on average, 5X faster run time when compared to an existing, state-of-the-art placement tool. This thesis also shows that the proposed algorithm delivers promising preliminary results in minimizing the critical path delay while maintaining high placement quality.Dept. of Electrical and Computer Engineering.

Secondary School Variables in Predicting Technology, Engineering, Mathematics (TEM) Major Choice
This paper addresses the growing body of research into factors that can influence the decision for high school students to enter into a Technology, Engineering, Mathematics (TEM) major in college. A total n of 691, including 372 TEM majors (143 females and 229 males) were selected from the Education Longitudinal Study of 2002 (ELS, 2002) using propensity matching. A Structural Equation Modeling (SEM) methodology was utilized in the Social Cognitive Career Theory framework and showed good model fit in the whole group, female only and male only groups. Though intent to major was a strong predictor, observed gender differences were observed related to latent and endogenous variables
The Effect of Economic Globalization on the Economic Growth-A Study on Foreign Portfolio Investment, Foreign Direct Investment, Export and Import in 1982-2017 Period: A Case Study in China
In the context of economic globalization, countries around the world are closely linked through economic activities such as import, export, foreign direct investment and foreign portfolio investment. Economic globalization is conducive to participating in the international division of labor, giving play to its comparative advantages and expanding overseas markets. This research is an ex post facto study using quantitative. The data used are as many as 35 data from 1982 to 2017. This study aims to determine the effect of economic globalization on economic growth, study: Foreign Portfolio Investment, Foreign Direct Investment, import and export, both directly or indirectly. The data ware validated using the VAR model, the results of this study indicate that the effects of variables on economic growth are positive
The uniqueness and iterative properties of solutions for a general Hadamard-type singular fractional turbulent flow model
In this paper, we consider the iterative properties of positive solutions for a general Hadamard-type singular fractional turbulent flow model involving a nonlinear operator. By developing a double monotone iterative technique we firstly establish the uniqueness of positive solutions for the corresponding model. Then we carry out the iterative analysis for the unique solution including the iterative schemes converging to the unique solution, error estimates, convergence rate and entire asymptotic behavior. In addition, we also give an example to illuminate our results
Solvability for a system of Hadamard fractional multi-point boundary value problems
In this paper, we study a system of Hadamard fractional multi-point boundary value problems. We first obtain triple positive solutions when the nonlinearities satisfy some bounded conditions. Next, we also obtain a nontrivial solution when the nonlinearities can be asymptotically linear growth. Furthermore, we provide two examples to illustrate our main results
