The performance of router directly impacts the Network-on-Chip (NoC) performance. This paper focus on developing efficient microarchitecture of allocator in the router and proposed matrix-diagonal allocator with high matching quality and low packets latency. The allocator, taking advantage of the fact that each element in the diagonal doesn't share the same row or column, includes matrix-diagonal...
A clearance effect evaluation index system is presented in this paper. Based on the clearance effect evaluation index system and cost processing models, an integrated optimization method for mechanisms with clearance joints is proposed. As a case study, a planar 3-RRR parallel robot with clearance joints is investigated. On the basis of the optimization results, a prototype is designed and manufactured...
All the cores of a many-core chip cannot be active at the same time, due to reasons like low CPU utilization in server systems and limited power budget in dark silicon era. These free cores (referred to as bubbles) can be placed near active cores for heat dissipation so that the active cores can run at a higher frequency level, boosting the performance of active cores and applications. Budgeting inactive...
This paper presents a pattern division multiple access (PDMA) concept for cellular future radio access (FRA) towards the 2020s information society. Different from the current LTE radio access scheme (until Release 11), PDMA is a novel non-orthogonal multiple access technology based on the total optimization of multiple user communication system. It considers joint design from both transmitter and...
Poor retrieval performance significantly degenerates users' experience of visual search, especially in mobile search. Ideally, users would like to be alerted when bad queries are present, which helps eliminate latency as well as waste of bandwidth, especially in 3G wireless environment. In this paper, we propose a visual query performance prediction (v-QPP) approach to predict the retrieval effectiveness...
In this work, we use game theory to analyze the spectrum allocation problem of cognitive radio networks. To deal with the multi Nash equilibrium problem of non-cooperative game based spectrum sharing in cognitive radio networks, we use the variation of utility of cognitive users to judge the stability after several iterations, and design an improved non-cooperative spectrum allocation algorithm. Simulation...
Agent-construction system is an innovative management method for the Chinese government in delivering public project, in which the government client choose a professional company to undertake the managing responsibilities of investment and construction, and hand over to the user party when the project completed. In agent-construction system, the agent (the professional company) implements the developer's...
During a PPP (public private partnership) project procurement, the private contractors priced the risk metrics and further negotiation has to be carried out until bother parties finally reach an agreement and sign the contract. The negotiations should consider whether the public sector should either accept the high risk cost, share the risks with the public sector, or retain the risk in the public...
A new, likelihood-based non-uniform allocation of Gaussian kernels in scalar (feature) dimension is proposed to compress complex, Gaussian mixture-based, continuous density HMMs into computationally efficient, small footprint models. Different from the objective of the previously proposed Kullback-Leibler divergence-based (KLD-based) allocation (Li et al., 2005), which is to make a better representation...
