This paper proves some topological properties of bitonic sorters, which have found applications in constructing, along with banyan networks, internally nonblocking switching fabrics in future broadband networks. The states of all the sorting elements of an N œ N bitonic sorter are studied for four different input sequences ai i N ; @ =1, bi i N ; @ =1, ci i N ; @ =1, and di i N ; @ =1, where ai...

We have constructed a simple device by which the optimal delay time between optical measurement of a cell and the application of the droplet charging pulse can be determined directly in a flow sorter. The device consists of a stainless steel chamber in which the sorted droplets are collected. In the collection chamber the collected droplets run through a capillary where a continuous fluorescenc...

In order to improve the adaptability of sweet cherry sorters cherries, a full-view-type grading cup for automated was developed based on physical characteristics three species cherries: Tieton, Huang Mi, and Lapins. The structure working principle are described in this paper. main factors affecting operating stability were identified study by analyzing mechanical properties cherries during conv...

Ajtai, Komlós, and Szemerédi constructed sorting networks with N wires of depth O(logN ). They were not concerned with the value of the proportionality constant implicit in the O-notation; subsequently Paterson replaced the O(logN ) by c log2 N with c under 6100. We describe an implementation of a more recent, and as yet unpublished, proposal of Ajtai, Komlós, and Szemerédi, that yields a small...

A self–routing permutation network is a connector which can set its own switches to realize any one-to-one mapping of its inputs onto its outputs. Many permutation networks have been reported in the literature, but none with self–routing property, except crossbars and cellular permutation arrays which have excessive cost. This paper describes a self–routing permutation network which has O(log n...

BACKGROUND Flow cytometer cell sorters have become important tools in many biological laboratories. Commercial electrically-deflected cell sorters that deflect wanted cells in electrically charged droplets need high-voltage amplifiers which are expensive and difficult to obtain. Effort was made to build an alternative droplet charging circuit with low-voltage amplifiers that are much easier to ...
