Nowadays, open data has become more and more popular and is widely used in a variety of service domains. However, in Taiwan, most open datasets are still separate while linked open data (LOD) is still lacking. Without LOD, application developers are difficult to locate and combine appropriate open datasets to create innovative applications. Therefore, to facilitate the consumption and the spreading...
We propose a composite decode-forward (DF) scheme for the two-way relay channel in the full-duplex mode by combining coherent, independent, and partial relaying strategies. The relay partially decodes each user’s information in each block and forwards this information coherently with the source user to the destination user in the next block as in block Markov coding. In addition, the relay independently...
The retrieval and the composition of information from multiple apps, services, or local resources can be time-consuming, costly, and inconvenient. To build an effective, efficient, and easy-to-use mobile service composition and delivery approach, in this research, we propose an approach called CARSB (Composite App with RESTful Services and Bricks). In CARSB, we introduce the concept of Service Brick,...
We propose two coding schemes combining decode-forward (DF) and noisy network coding (NNC) with different flavors. The first is a combined DF-NNC scheme for the oneway relay channel which includes both DF and NNC as special cases by performing rate splitting, partial block Markov encoding and NNC. The second combines two different DF strategies and layered NNC for the two-way relay channel. One DF...
We design novel partial decode-forward (PDF) schemes for the Gaussian two-way relay channel with direct link. Different from pure decode-forward, each user divides its message into two parts and the relay decodes only one part of each. The relay then generates its codeword as a function of the two decoded parts and forwards to the two users. We propose PDF schemes for both the full- and half-duplex...
Phosphorous (P) deficiency of soils is one of the major yield-limiting factors worldwide. The most economic and efficient strategy for sustainable agriculture is to breed varieties with P-deficiency tolerance. The objective of this study was to map QTLs for P-deficiency tolerance in soybean, which could lay theoretical foundation on molecular marker assisted selection in soybean with improved P-deficiency...
We consider the full-duplex two-way relay channel with direct link between two users and propose two coding schemes: a partial decode-forward scheme, and a combined decode-forward and compute-forward scheme. Both schemes use rate-splitting and superposition coding at each user and generate codewords for each node independently. When applied to the Gaussian channel, partial decode-forward can strictly...
We consider the role of Wyner-Ziv binning in compress-forward for relay channels. In the one-way relay channel, we analyze a compress-forward scheme without Wyner-Ziv binning but with joint decoding of both the message and compression index. It achieves the same rate as the original compress-forward scheme with binning and successive decoding. Therefore, binning helps reduce decoding complexity by...
In the Meridian Project, two space weather physics models, L1-magnetosphere-ionosphere causal chain(L1 model), and numerical magnetosphere database service, are provided as e-Science application services through the space weather computation grid environment, which provides a web-based portal for space weather studies users. We call the computation grid environment as a computing gateway. The computing...
