Wireless sensors are limited by node costs, communication efficiency, and energy consumption when wireless sensors are deployed on a large scale. The use of submodular optimization can reduce the deployment cost. This paper proposes a sensor deployment method based on the Improved Heuristic Ant Colony Algorithm-Chaos Optimization of Padded Sensor Placements at Informative and cost-Effective Locations (IHACA-COpSPIEL) algorithm and a routing protocol based on an improved Biogeography-Based Optimization (BBO) algorithm. First, a mathematical model with submodularity is established. Second, the IHACA is combined with pSPIEL-based on chaos optimization to determine the shortest path. Finally, the selected sensors are used in the biogeography of the improved BBO routing protocols to transmit data. The experimental results show that the IHACA-COpSPIEL algorithm can go beyond the local optimal solutions, and the communication cost of IHACA-COpSPIEL is 38.42%, 24.19% and 8.31%, respectively, lower than that of the greedy algorithm, the pSPIEL algorithm and the IHACA algorithm. It uses fewer sensors and has a longer life cycle. Compared with the LEACH protocol, the routing protocol based on the improved BBO extends the life cycle by 30.74% and has lower energy consumption.

With the improvement of the national IP strategy and system, the number of IP applications and grants is increasing between high-tech enterprises. It is an important issue to business managers of high-tech companies that how to use the intellectual property effectively. This paper summed up the important roles of patent management in Ningbo, analyzes the maturating conditions, mechanism and models of technological achievements, it provides the corresponding countermeasures of patent management.

Port development has benefited from the development of international trade and shipping. The pattern of international trade and the change of shipping also affect the adjustment of port layout. Nowadays, regional economic integration as new trade pattern which promote port constantly improve on the function and operation. The development of the large scale of the ship, to some extent, restricted the growth of the number of service loops. But on the other hand, service quality improving is required. Therefore, the port and its economic circle cooperation is the best way to fit new trade pattern. This paper is to research on cooperative mechanism among APSN for Ningbo port.
