This paper considers an M-member "individual-based" continuous time swarm model with individuals moving with a nutrient profile (or an attractant/repellent) in an n- dimensional space. It is proved that the swarm members aggregate and eventually form a cohesive cluster of finite size for Gaussian Profiles. Moreover, all the swarm members will converge to more favorable areas of the Gaussian...
Using the Krugman index, we calculate the regional specialization of 29 provinces' service sector in China. Further, we analyze some specific industries of the service sector through the location quotient. Then we compare the degree of specialization between each other of 10 provinces. The main conclusions of this paper are: Firstly, the average specialization of service sector is lower than manufacture...
Crystal proteins are produced by the gram-positive bacterium Bacillus thuringiensis (Bt) during sporulation. The cry1le genes were silent in Bt strains, but can be over expressed in Escherichia coli BL21 (DE3) in inclusion bodies, and the expressed product was toxic to Plutella xylostella, Ostrinia furnacalis, and soybean pod borer (Leguminivora glycinivorella). In order to know the N-terminal and...
This paper considers a swarm model with an attraction-repulsion function involving variable communication time lags and an attractant/repellent. It is proved that for quadratic attractant/repellent profiles the members of the swarm with time delays will aggregate and form a cohesive cluster of finite size in a finite time. Moreover, all the swarm members will converge to more favorable areas of the...
This paper proposes a method for Web services test case generation, which is centered on a practical test data generation framework that has higher probability to penetrate the service implementation logic. This presented framework leverages both the information contained in the WSDL/XSD files and the information provided by testers as well as enables testers to customize the fields to be tested,...
Firstly, we give the definition of an L-bifuzzy Scott closed subset and prove its related properties, then, we give the definition of an L-bifuzzy Scott co-topological space, study its properties and equivalently characterize it which is a generalization of the Scott co-topological space in the classical topology theory. Finally, we establish the relationships of L-bifuzzy domain, L-bifuzzy lower...
This paper considers an M-member "individual-based" continuous time swarm model with individuals that moving with a nutrient profile (or an attractant/repellent) in an n-dimensional space. The swarm behavior is a result of a balance between inter-individual interplays as well as the interplays of the swarm agents with their environment. It is proved that the swarm members aggregate and eventually...
Firstly, we present some characterizations of L-fuzzy poset and their corresponding proofs. Then, we give the definition of L-fuzzy upper set and prove its related properties. Next, we define the concept of L-fuzzy Co-Alexandrov topological space on an L-fuzzy poset (X, e). We further study the properties of L-fuzzy Co-Alexandrov topological space and equivalent characterizations, which are generalizations...
A new iterative learning control method is presented for the trajectory tracking control of linear time-variant systems. This new method does not need detailed knowledge of the controlled system. However, a reference batch is designed, in which some small change of the input trajectory in the current batch is applied to the controlled system, and then its output trajectory is obtained. The ratio of...
In this paper the performance of passive UHF RFID bow tie tag with different impedance matching was analyzed by simulation and measurement. Tag antenna design differs from conventional antennas. In tag design, when the PRC of tag is up to -7 dB or -8dB, it can be considered as good tag and even as low as -5 dB PRC is sufficient for several application. However, Co-Design is recommended for the application...
The PowerPoint presentation work has introduced a novel dynamic frequency planning approach to the frequency assignment problem tailored to OFDMA networks. DFP may decrease the inter-cell interference and increase the capacity of the network by dynamically adapting the radio frequency parameters to the specific scenario. DFP uses novel algorithms to sense the radio channel, and adapted versions of...
