Container on-site wastewater treatment plants are systems of growing interest in the areas where sewer cannot be implemented. In this study, container plant with low-loaded activated sludge has been examined. The aim study was: (i) to assess efficiency plant; and (ii) evaluate relationship between condition selected parameters effluent quality. Effluent quality characterized by reliability fact...

Faculty of Symbiotic Systems Science, Fukushima University, Fukushima City, 960-1296, Japan This paper focuses on efficiency of simulation-based optimization for container terminal operation system. Firstly, the discrete-event simulation model of multimodal operation system on container terminal was presented with the queuing network, for which the mathematical optimization model of resource al...

The synchronous interaction between a sloshing fluid and its container may take place when the motion of the container is not prescribed a priori. When a partially-filled container is suspended as a bifilar pendulum, the fluid contributes to the restoring force by its weight through the wire suspensions and may either augment or diminish the restoring force through hydrodynamic interaction with...

For high-confidence systems, substantial effort is expended to ensure that the system will behave in an expected manner. This paper presents the position that a commercial off the shelf Enterprise JavaBeansTM (EJBTM) container can be extended to constrain the behavior of high confidence software. These extensions are based on techniques that are not new; developers of high confidence software u...

The container terminal is a convergence point in the cargo flow, being a focal point for multiple supply chains. The operations performed in a container terminal involve one of the most complex environments within the transport industry. A container terminal plays a critical role in international shipping and is under pressure to cope with increasing container traffic. This paper presents a mul...

In Euclidean d-spaces, the container problem asks to pack n equally sized spheres into a minimal dilate of a fixed container. If the container is a smooth convex body and d ≥ 2 we show that sequences of solutions to the container problem can not have a “simple structure”. By this we in particular find that there exist arbitrary small r > 0 such that packings with spheres of radius r into a smoo...

In an Euclidean d-space, the container problem asks to pack n equally sized spheres into a minimal dilate of a fixed container. If the container is a smooth convex body and d ≥ 2 we show that solutions to the container problem can not have a “simple structure” for large n. By this we in particular find that there exist arbitrary small r > 0, such that packings in a smooth, 3-dimensional convex ...

In this contribution we optimize the transportation of containers in the hinterland of a local area with one terminal and one depot for empty containers and trucks. There are several customers who want to receive goods by inbound containers and several customers who want to ship goods by outbound containers. Additionally, there are empty inbound containers and empty outbound containers. We pres...

The flow field and the motion of the free surface in an oscillating container are simulated numerically to assess the numerical approach for studying two-phase flows under oscillating conditions. Two numerical methods are compared: one is to model the oscillating container directly using the moving grid of the ALE method, and the other is to simulate the effect of container motion using the osc...

We consider the container loading problem that occurs at many furniture factories where product boxes are arranged on product pallets and the product pallets are arranged in a container for shipments. The volume of products in the container should be maximized, and the bottom of each pallet must be fully supported by the container floor or by the top of a single pallet to simplify the unloading...
