We consider the movement minimization problem in a conveyor flow shop processing controlled by one worker for all machines. A machine can only execute tasks if the worker is present. Each machine can serve as a bu¤er. The objective is to minimize the total number of movements of the worker for the processing of all jobs. Such minimization problems usually appear in conveyor controlled manufactu...

A new current conveyor block, called a balanced-output third generation inverting current conveyor (ICCIII+−), is introduced in this paper. A novel CMOS realization for this block is proposed. To show the strength of this block, many applications are given, such as integrators, filters, and an oscillator. The proposed ICCIII+− and the presented applications are tested with SPICE simulations usi...

A novel four-input three-output voltage-mode differential difference current conveyor (DDCC) based universal filter is presented. The circuit uses three DDCCs as active elements, two resistors and two capacitors as passive elements. The circuit along with its versatility enjoys the advantage of minimum number of passive elements employment. SPICE simulation results are given to confirm the theo...

A new terminology (order, kind, class) and the classification and definition of multi-port current conveyors are given. The generalized current conveyor is defined as a tool for synthesis. Several autonomous circuits containing multi-port conveyors are presented. The design of ARC oscillators and second-order filters based on the given autonomous networks is described in this paper.

NATURE METHODS | VOL.10 NO.4 | APRIL 2013 | 361 We present a genome-wide approach to map DNA double-strand breaks (DSBs) at nucleotide resolution by a method we termed BLESS (direct in situ breaks labeling, enrichment on streptavidin and next-generation sequencing). We validated and tested BLESS using human and mouse cells and different DSBs-inducing agents and sequencing platforms. BLESS was a...

The well known problem of priority inversions that occurs in classical real-time systems also manifests in decentralized cyber-physical systems. Using a specific example of composable conveyor systems, we show how priority inversions hinder the transport of entities through the conveyor systems. We present a novel adaptation of the classical priority inheritance protocol for resolving these cyb...

Many problems which occur with belt conveyors can be attributed to system dynamics and the associated variations in belt tension. Material spillage, belt and splice failure, belt lift-off in vertical curves and poor tracking are a few examples of situations where knowledge of the dynamic tensions would be of benefit in eliminating a problem. The difficulty is that measuring dynamic tension at a...
