Joint Resource Allocation for eICIC in Heterogeneous Networks

Interference coordination between high-power macros and low-power picos deeply impacts the performance of heterogeneous networks (HetNets). It should deal with three challenges: user association with macros and picos, the amount of almost blank subframe (ABS) that macros should reserve for picos, and resource block (RB) allocation strategy in each eNB. We formulate the three issues jointly for sum weighted logarithmic utility maximization while maintaining proportional fairness of users. A class of distributed algorithms are developed to solve the joint optimization problem. Our framework can be deployed for enhanced inter-cell interference coordination (eICIC) in existing LTE-A protocols. Extensive evaluation are performed to verify the effectiveness of our algorithms.Comment: Accepted by Globecom 201

Global convergence of the nonmonotone MBFGS method for nonconvex unconstrained minimization

AbstractIn this paper, we propose a new nonmonotone Armijo type line search and prove that the MBFGS method proposed by Li and Fukushima with this new line search converges globally for nonconvex minimization. Some numerical experiments show that this nonmonotone MBFGS method is efficient for the given test problems

Cycle tracks evaluation in West Campus in Austin, Texas

textThis research evaluated the performance of two types of cycle tracks—a one-way cycle track on Guadalupe St. and a two-way cycle track on Rio Grande St. in West Campus. The evaluation focused on all types of traffic users' (including bicyclists, pedestrians and motorists) behavior and their perspectives regarding safety, comfort and operation. For each cycle track, all users' behavior and their interactions with others was observed at the main intersection for a cumulative 4 hours; and 35 intercept surveys, including 15 cyclist surveys, 10 pedestrian surveys and 10 motorist surveys, were collected to identify all types of traffic users' experiences, perceptions and attitudes toward the cycle tracks. Overall, the results indicate that the cycle tracks have improved the sense of safety and comfort for cyclists, but, at the same time, other people—including pedestrians—misuse the space, resulting in potential safety issues with the existing intersection design that might undermine overall success.Community and Regional Plannin

Ideological and political teaching practice of electrical specialty courses in colleges and universities

In the personnel training wo rk in colleges and universities, the basic task of establishing a person through each link, is always the goal that our country’s higher education pursues. In the background of the new period, how to penetrate the ideological and political content in the electrical course, construct the new model of the course ideological and political, become the key topic that the electrical teacher needs to explore. In order to cultivate the students of this major into high-quality talents with both morality and ability, the teachers of electrical major courses need to establish the ideological and political teaching model suitable for this major course as soon as possible. Based on this, this paper probes into the practical strategies of ideological and political teaching of electrical major courses in colleges and universities, in order to provide valuable reference for the majority of colleagues
