In this paper, a special case of the vehicle routing problem in which the demands consist in a set of rectangular two-dimensional weighted items is considered. The vehicles have a two-dimensional loading surface and a maximum weight capacity. These problems have a routing and a packing component. A framework to handle the loading of a vehicle is proposed. A Constraint Programming loading model ...

Transmission of several scattered users to a central base station over frequency-selective channels (multiple access problem) is considered. Multicarrier transmission and frequencydivision multiplexing in disjoint bands are assessed with regard to the achievable rate regions. The application of power loading in these schemes aiming at a maximization of the rate regions is discussed. Performance...

In this article optimal design of shear walls is performed under seismic loading. For practical aims, a database of special shear walls is created. Special shear walls are used for seismic design optimization employing the charged system search algorithm as an optimizer. Constraints consist of design and performance limitations. Nonlinear behavior of the shear wall is taken into account and per...

In this thesis we build the parametric mathematical model of machine tool and solid models of traction gears using in subway locomotive by analyzing the machining process of involute gears and meshing principle of involute gears. The optimization design is done through deduce the relations between basic parameters of gear and loading capacity of transmission. On the base of analyzing optimizati...

For track-based robots, an important aspect is the suppression design, which determines the trafficability and comfort of the whole system. The trafficability limits the robot's working capability, and the riding comfort limits the robot's working effectiveness, especially with some sensitive instruments mounted on or operated. To these aims, a track-based robot equipped with a novel passive bi...

Foundations of structures which are subjected to uplift loading require anchoring systems to resist pullout loads. Such anchors can be broadly classified as gravity anchors, pile anchors and plate anchors. Plate anchors can be circular, square or strip in shape. The loading applied on plate anchors can be vertical, inclined or horizontal depending on the anchor orientation. In this study, vario...

Nanostructured materials have shown significant potential for biomedical applications that require high loading capacity and controlled release of drugs. Nanoporous gold (np-Au), produced by an alloy corrosion process, is a promising novel material that benefits from compatibility with microfabrication, tunable pore morphology, electrical conductivity, well-established gold-thiol conjugate chem...

For practical application of lithium-sulfur batteries (LSBs), it is crucial to develop sulfur cathodes with high areal capacity and cycle stability in a simple and inexpensive manner. In this study, a carbon cloth infiltrated with a sulfur-containing electrolyte solution (CC-S) was utilized as an additive-free, flexible, high-sulfur-loading cathode. A freestanding carbon cloth performed double ...

OBJECTIVES A protocol was designed to produce albumin-coated microbubbles (MBs) loaded with functionalized polylactide (PLA) nanoparticles (NPs) for future drug delivery studies. METHODS Microbubbles resulted from the sonication of 5% bovine serum albumin and 15% dextrose solution. Functionalized NPs were produced by mixing fluorescent PLA and PLA-polyethylene glycol-carboxylate conjugates. N...
