The artificial biomass based on three biomass components (cellulose, hemicellulose and lignin) were developed on the basis of a simplex-lattice approach. Together with a natural biomass sample, they were employed in enzymatic hydrolysis researches. Different enzyme combines of two commercial enzymes (ACCELLERASE 1500 and OPTIMASH BG) showed a potential to(More)
With the development and prosperity of ultra wideband (UWB) technologies, the multiple access UWB system has been a hot research topic. Multiuser detection technique has the potential to enlarge the system capacity in multiple access UWB communication environments. In this paper, a new hybrid multiuser receiver is proposed for DS-UWB system. To implement(More)
Compatibility of Web services states the fitness of service peers that interact each other. It covers both static properties and dynamic behavior of Web services. Most researches deal with compatibility issue in the context of static checking. In this paper, we use a formal method, say CCS, to describe dynamic behavior of Web services. The formalization(More)
This paper presents an adaptive sub-carrier and power allocation scheme for orthogonal frequency division multiple access (OFDMA) systems according to their different quality of service (QoS) requirements and traffic type. The algorithm maximized the transmission data rate while satisfying total power constraint and a certain bit error rate (BER)(More)
This paper proposes entitymetrics to measure the impact of knowledge units. Entitymetrics highlight the importance of entities embedded in scientific literature for further knowledge discovery. In this paper, we use Metformin, a drug for diabetes, as an example to form an entity-entity citation network based on literature related to Metformin. We then(More)
The main purpose of the Semantic Web is driving the evolution of the current Web by enabling users to find, share, and combine information more easily. OWL ontologies play a key role in this effort. It is widely believed that the majority of current Web data sources are powered by relational databases (RDB). Thus developing approaches and tools for(More)
Full implementation of the Semantic Web requires widespread availability of OWL ontologies. Manual ontology development using current OWL editors remains a tedious and cumbersome task that requires significant understanding of the new ontology language and can easily result in a knowledge acquisition bottleneck. On the other hand, abundant domain knowledge(More)
This paper proposes a plane-based sampling method to improve the traditional Ray Casting Algorithm (RCA) for the fast reconstruction of a three-dimensional biomedical model from sequential images. In the novel method, the optical properties of all sampling points depend on the intersection points when a ray travels through an equidistant parallel plan(More)
The compatibility analysis is absolutely necessary for guaranteeing the correct composition of web services, no matter what styles the composition takes, statically or dynamically. In this paper, we provide a formalization of web services behavior using the approach of automata. With this understanding, we propose a definition of role among web services(More)
