Maritime accidents and incidents, such as ship to ship collision or ship grounding, most often occur near ports due to the intensive water traffic and shallow water depth. The occurrence of those accidents place a port in a very dangerous situation, since the port could suffer from a high risk of blockage of port entry, and the consequent economic loss can be substantial. In the case of maritime accidents,...
This paper presents a project that allows the Baxter humanoid robot to play chess against human players autonomously. The complete solution uses three main subsystems: computer vision based on a single camera embedded in Baxter's arm to perceive the game state, an open-source chess engine to compute the next move, and a mechatronics subsystem with a 7-DOF arm to manipulate the pieces. Baxter can play...
International Maritime Organization (IMO) proposed the Ship Energy Efficiency Operational Indicator (EEOI) to evaluate the energy efficiency of ships in service. During the implementation of the EEOI, the effective monitoring and optimization management of ship energy efficiency is very important. In this paper, the ship energy efficiency monitoring and control system considering the environmental...
Heterogeneous Computing is becoming an important technology trend in HPC, where more and more heterogeneous processors are used. However, in traditional node architecture, heterogeneous processors are always used as coprocessors. Such usage increases the communication latency between heterogeneous processors and prevents the node from achieving high density. With the purpose of improving communication...
Regular expression matching has become a critical yet challenging technique in content-aware network processing, such as application identification and deep inspection. To meet the requirement for processing heavy network traffic at line rate, Deterministic Finite Automata (DFA) is widely used to accelerate regular expression matching at the expense of large memory usage. In this paper, we propose...
Modern networks are increasingly becoming content aware to improve data delivery and security via content-based network processing. Content-aware processing at the front end of distributed network systems, such as application identification for datacenter load-balancers and deep packet inspection for security gateways, is more challenging due to the wire-speed and low-latency requirement. Existing...
The traditional system controller in symmetric multi-processors (SMP) controls the memory, so it is suitable for the shared memory programming model. With the emergence of the processors which integrate memory controllers, the system controller seems less important than before. However, since the system controller resides in the center of a computer system, it acts as an artery which directly connects...
The blade system is very popular in high performance computing. In a blade system, the blade is a fundamental element in which are symmetric multi-processors (SMP). About ten blades constitute a blade box, several blade boxes constitute a cabinet and some cabinets constitute a blade system at last. The blades in a blade box are neighbors because they have relatively short distance. Programmers always...
According to the development of the TOP500, the performance of the high performance computers (HPCs) is increasing rapidly. The incredible performance increment of the HPCs should be largely attributed to the development of their communication systems, because the HPCs cannot extend to such a large scale without their excellent communication systems. As an important member of the communication system,...
Heterogeneous grid workflow management plays an important role in the grid interoperation. It integrates service resources from different grid systems and packs them as atomic services into a composite service. The focuses of the research are how to shield the difference among the heterogeneous grid services and how to provide a flexible way to compose services. Heterogeneous grid workflow management...
