In this paper, the fuzzy multi-depot vehicle routing problem with simultaneous pickup and delivery (FMDVRP-SPD) is investigated. The FMDVRP-SPD is the problem of allocating customers to several depots, so that the optimal set of routes is determined simultaneously to serve the pickup and the delivery demands of each customer within scattered depots. In the problem, both pickup and delivery dema...

In this paper, we address the problem of load selection and pickup-dispatching of multiple-load AGVs. Various load-selection rules and pickup-dispatching rules are proposed and studied. The objective of this study is twofold. We want to understand not only the performance of load-selection rules and pickup-dispatching rules in two performance criteria—throughput and tardiness, but also the effe...

In mammals, the oocyte and its surrounding cumulus cells constitute on oocyte cumulus complex (OCC). During ovulation, OCCs are extruded into the peritoneal or bursal cavity, depending on the species, and are then rapidly picked up by the fimbria on the outer surface of the oviductal infundibulum and transported to the ampulla, where fertilization occurs. We developed a method to measure OCC pi...

Interstellar pickup ions are dynamically important in the outer heliosphere where they mass-load and heat the solar wind. Some of these pickup ions are transformed into energetic neutral atoms (ENAs) by charge exchange with the residual cold interstellar gas that is the primary constituent of the outer heliosphere. The most detailed measurements of interstellar pickup ions in the heliosphere ar...

Pickup ions, created by ionization of slow moving atoms and molecules well inside the heliosphere, provide us with a new tool to probe remote regions in and beyond the heliosphere and to study injection and acceleration processes in the solar wind. Comprehensive and continuous measurements of H, He, C, N, O, Ne and other pickup ions, especially with the Solar Wind Ion Composition Spectrometer (...

Isotopically resolved cross sections and velocity distributions have been measured in charge-pickup reactions of 1 A GeV Pb with proton, deuterium and titanium target. The total and partial charge-pickup cross sections in the reactions Pb + H and Pb + H are measured to be the same in the limits of the error bars. A weak increase in the total charge-pickup cross section is seen in the reaction o...

Optically corrected pickup method of both virtual and real objects for integral imaging is proposed. The proposed pickup system has imbricate view volumes which are equivalent to those in the integral imaging display. Therefore, there is no distortion resulting from the discord in directions of elemental image between pickup and display. In this system, the view volumes are transformed by 4f op...

We have developed a straw tube chamber with pickup-pad readout. The mechanism for signal pickup, the size of the pickup signal, and the distribution of signals among neighboring pads are discussed. We have tested a prototype chamber in a beam test at Brookhaven National Laboratory and have measured chamber e$ciencies in excess of 99%. ( 1999 Elsevier Science B.V. All rights reserved.

Last time we considered at some length the sources of random noise due to the thermal motion of ions and electrons. Now we turn to the practical matter of dealing with the pickup of nonrandom electrical signals, such as interference from the 60 Hz power lines or from a computer monitor. There are two main principles to consider: electrostatic pickup through unshielded surfaces, and magnetic pic...
