Given a set of k disjoint convex polygonal obstacles inside a triangular container, we add straight-line noncrossing edges such that each obstacle has three vertex-disjoint paths to the container. We prove combinatorial bounds on the minimum number of edges that are always sufficient and sometimes necessary. Figure 1: A triangular container with disjoint convex obstacles.

the dramatic increasing of sea-freight container transportations and the developing trend for using containers in the multimodal handling systems through the sea, rail, road and land in the present market cause some challenges to the general managers of container terminals such as increasing demand, competitive situation, new investments and expansion of new activities and the need to use new m...

It is well known that the content management system (CMS) and the broadcast management system (BMS) are the most essential components of an IPTV system. An IPTV system retrieves container files from the CMS and delivers them to the end users through the BMS. Therefore, most of research works about IPTV systems handle container files. However, a container is a mix of video, audio, computer graph...

Container transportation has gradually become the main direction of the development of shipping today. With the ship's large-scale, specialization and modernization the development of handling capacity of modern container terminal plays a key role in low-cost transportation, and efficient circulation. Automated container terminal can not only improve the utilization rate of equipment, reduce op...

The DARELUX project envisages long-term storage of hydrology measurement data in a permanent archive. In order to make the DARELUX hydrology data sets accessible in an unknown future, a future-proof metadata element set is wanted. An analysis of current standards and best practices for metadata lead to the choice of the metadata of the Dublin Core Metadata Element Set, with an addition of archi...

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 ...
