Seaport container terminals are essential nodes in sea cargo transportation networks. As such, the operational efficiency of container terminals in handling containers passing through them plays a critical role in a globalized world economy. Many models and algorithms have been developed to address various decision problems in container terminals to help(More)
This paper develops a parallel evolutionary algorithm based design unification of linear control systems in both the time and the frequency domains under performance satisfactions. A speedup of near-linear pipelinability is observed for the parallelism implemented on a network of transputers of Parsytec SuperCluster. The approach is capable of tackling(More)
Intravenous administration of hapten-coupled epidermal cells (EC) induces tolerance in mice. To assess the relevance of this observation to cutaneous tumors, the ability of EC to induce tolerance to the S1509a spindle cell tumor (H-2a) was examined. ECs were prepared from CAF1 (H-2a/d) mice and the supernatant from a freeze-thaw lysate of S1509a cells was(More)
In this paper, we investigate how two main factors affect the efficiency of the port operation. The two main factors are type of transport vehicles and layout of the storage yard. Two different types of transport vehicles (i.e., prime mover and shuttle carrier) and two different types of layouts (i.e., with or without chassis lane beside the container(More)
Operators of busy container terminals need to periodically evaluate options for capacity expansion in order to meet the increasing demands for container handling at their terminals. When planning such capital intensive investments, it is important to find an efficient and effective way to design and evaluate various possible terminal layout and equipment(More)
Aqueous root extract of Selayak Hitam a plant commonly found in Malaysian jungles and reported to have abortifacient property was screened for oxytocic effect. Results obtained from in vitro experiments on isolated uterus preparation from both pregnant and non pregnant rats and in vivo experiments on uterus contraction in rats in situ, showed that the(More)
In transshipment ports, the loading and unloading activities are both concentrated and inevitably happen at the same time. Thus the storage yard management is more challenging than that in a general import-export container terminal. Our studies on storage yard management can be divided into three phases, namely yard sectioning, yard template planning and(More)
