With the trend of terminal automation and requirement for port operation efficiency to be greatly improved, it is very necessary optimize traveling route automatic guided vehicles (AGV) with reference connection loading unloading equipment. As a complex multi-equipment system, inevitable that AGV will collide when due various accidents in actual operation, which lead locking reduce operation. C...

Here, a single-input, dual output (SIDO) coupled inductor-based high voltage conversion ratio DC–DC converter is proposed. The proposed has the capability of operating as SIDO in way that terminal input source exchangeable among three ports. Therefore, there are different operation modes for converter. ratios ports over low port can be improved by increasing turn inductors. main advantage achie...

The role of ports goes far beyond the traditional function of a pure transport node linking sea and landside transportation. Rather, many ports offer value-added logistics and auxiliary services leading to a network of container flows. Moreover, containers may need to be transferred between different areas within the port. Information exchange and optimization is necessary to efficiently coordi...

With the continuous development of smart ports, construction port information systems has become focus future such ports. However, existing performance evaluation system for represents a research gap. It cannot effectively achieve specific improvement in services and capabilities. In this paper, an index was forged from three perspectives operating level, management capability, economic efficie...

Despite efficient carbon monitoring system and the commercialization of battery technology for intra-port transportation, port management are found not adopting these environmental yet costly equipments. Port authority who regulates environmental policies lacks leverage to impose tangible reduction on emission through concession. This model integrates sustainability into port equipment expansio...

Productivity is an extremely important factor in the competitiveness of a container terminal. itself largely influenced by handling mechanisation, main task which to serve quay cranes on one side and yard other. One most effective types mechanisation this segment shuttle carriers, are used primarily larger terminals. The objective study was determine if they can also be effectively smaller term...

implantable ports are used for intravenous infusion therapy and play an important role in management of oncology patients. these ports are best suited for patients requiring long-term therapy (>4 weeks). implanted ports provide reliable venous access protect peripheral access increase patients’ comfort through reducing repeated and difficult vein punctures allow for safe and comfortable adminis...

Container terminal production is both an important and complicated element in the contemporary global economy. Amongst other methods, the efficiency of container port or terminal production can potentially be analysed by Data Envelopment Analysis (DEA) or by the Free Disposal Hull (FDH) Model. This paper aims to evaluate the efficiency of the world’s most important container ports and terminals...

The single pole-to-ground (SPG) fault is one of critical failures which will have a serious impact on the stable operation multi-terminal DC distribution network based modular multilevel converter (MMC). It very significant to analyze characteristics for detecting faults and protection design. This paper established SPG model, showed that in presence reactor, short-circuit current was reduced f...

Targeting issues in initial allocation of carbon emission allowance port industry, this study puts forth a mixed method that uses the baseline for handling production and historical intensity auxiliary allowance. This clarifies organizational boundary operational using method, analyzes related factors, provides computational formulas. In instance analysis, specific calculation process applying ...
