Tactics for Reading Comprehension

In recent years, reading comprehension is taking up a larger and larger part in almost every international test or domestic examination. Knowing the basic knowledge and grasping the test - taking tactics are key factors of good reading comprehension. In this thesis, I will dwell on nine commonly used tactics for reading comprehension. This will help you to deal with the problems with reading comprehension efficiently.     

Semi-blind Channel Estimator for OFDM-STC

Channel state information of OFDM-STC system is required for maximum likelihood decoding.A subspace-based semi-blind method was proposed for estimating the channels of OFDM-STC systems.The channels are first estimated blindly up to an ambiguity parameter utilizing the nature structure of STC,irrespective of the underlying signal constellations.Furthermore,a method was proposed to resolve the ambiguity by using a few pilot symbols.The simulation results show the proposed semi-blind estimator can achieve higher spectral efficiency and provide improved estimation performance compared to the non-blind estimator.

Data Migration for Ontology Evolution

Ontology is the conceptual backbone that provides meaning to data on the semantic web. However, ontology is not a static resource and may evolve over time, which often leaves the meaning of data in an undefined or inconsistent state. It is thus very important to have a method to preserve the data and its meaning when ontology changes. This paper proposed a general method that solves the problem using data migration. It analyzed some of the issues in the method including separation of ontology and data, migration specification, migration result and migration algorithm. The paper also instantiates the general mothod in RDF(S) as an example. The RDF(S) example itself is a simple but complete method for migrating RDF data when RDFS ontology changes.     

Investigating the Interaction Between Gluconobacter Oxydans and Bacillus M egaterium for 2-keto-L-gulonic Acid Biosynthesis in the Two-Step Vitamin C Fermentation

In the two-step vitamin C fermentation process, its precursor 2-keto-L-gulonic acid was synthesized from L-sorbose by mixed culture of Gluconobacter oxydans and Bacillus megaterium. The interaction between Gluconobacter oxydans and Bacillus megaterium remains unclear and it is a challenge to mathematically model the mixed growth of these two strains. The Monod-type equations were previously proposed to describe the coupled growth of Gluconobacter oxydans and Bacillus megaterium. However, in this study, we modeled the interaction of these two strains in a macroscopic view by introducing the population theory. Taking account of the fact that the density or concentration of Gluconobacter oxydans or Bacillus megaterium was hardly to measure accurately in the mixed culture broth, the data of concentrations of the substrate and product were used to indirectly investigate the relation between these two strains. Three batch experiments were used to validate our model. And according to the values of identified parameters, the type of interaction between Gluconobacter oxydans and Bacillus megaterium was concluded to be predation, where Gluconobacter oxydans was predator, and Bacillus megaterium was prey.

Genetic algorithm for multi-protocol label switching

A new method for multi-protocol label switching is presented in this study, whose core idea is to construct model for simulating process of accommodating network online loads and then adopt genetic algorithm to optimize the model. Due to the heuristic property of evolutional method, the new method is efficient and effective, which is verified by the experiments.

A New Fragile Watermark for Image

Fragile watermarking is a method to verify the integrity and authenticity of multimedia data. A new fragile watermark for image was proposed, which can be used in image verification applications. The paper first described the above two techniques, some of which will be used in the method. Then it described the embedding and authentication process and also analyzed the method to show how it can survive some attacks. The experimental results show that the proposed method doesn‘t need the watermark or original image on authentication side. It provides more security against attack, and can localize where the temoerinlz has occurred.
