the product rate variation problem minimizes the variation in the rate at which different models of a common base product are produced on the assembly lines with the assumption of negligible switch-over cost and unit processing time for each copy of each model. the assumption of significant setup and arbitrary processing times forces the problem to be a two phase problem. the first phase determ...

We consider the 0–1 Knapsack Problem with Setups (KPS). Items are grouped into families and if any items of a family are packed, this induces a setup cost as well as a setup resource consumption. We introduce a new dynamic programming algorithm which performs much better than a previous dynamic program and turns out to be also a valid alternative to an exact approach based on the use of an ILP ...

This paper describes a setup to synchronize data used to track speech articulators during speech production. Our method couples together an ultrasound, an electromagnetic and an audio system to record speech sequences. The coupling requires a precise temporal synchronization, to know exactly the delay between the recording start of each modality, and to know the sampling rate of each modality. ...

Recnetly, the demands of QoS(Quality of Service) and the traffic in network is increased. So, HMPLS(Hierarchical MPLS) network research what guarantees the scalability is in progress. But, the H-MPLS has a problem of increasing of groups and the links of these group's nodes. It happens a problem that is increasing of HMPLS setup cost. In this paper, we setup the H-MPLS groups. We use NS simulat...

We propose a framework for real-time monitoring of wireless biosensors. This will be a scalable platform that requires minimum human interaction during setup and monitoring. The main components include: (i) biosensor/transceiver pairs, (ii) smart hardware modules to automatically setup the body area network, (iii) data delivery mechanism to an internet sever, and (iv) automatic data collection,...

Remote labs are increasingly being used as an effective tool for letting students practicing with real experiments, with limited effort and cost. A multi-robot setup, based on the LEGOMindstorms technology and the Matlab environment, allowing students to experiment with real robots through the Internet, has been developed. In this paper, a novel feature of this setup is presented. The concept o...

this paper considers the economic lot scheduling problem, that is, the problem of scheduling several products on a single facility so as to minimize holding and setup costs. combination of frequency and timing as well as production quantity make this problem np-hard. a heuristic is developed to obtain a good solution to elsp. the proposed heuristic makes use of the simulated annealing technique...

Facility location (FL) is a well-researched problem in operational-research (Şahin Güvenç & Haldun, 2007), and is closely related to EBC. Given a set of N customers and M potential facilities to open, as well as costs sij for customer i to use facility j, and a facility setup cost cj associated with opening a facility j, we wish to find the set of facilities to open, as well as the assignments ...

This paper describes a laboratory setup suitable for implementing low cost real-time solutions in the fields of control, synchronization and information transmission based on chaotic oscillators. The setup has the following features: (a) it is composed of a Chua oscillator furnished with three actuators thus permitting monoand multi-variable control; (b) the actuators can be driven by the analo...

Radiocarbon ((14)C) concentrations at a 43 parts-per-quadrillion level are measured by using saturated-absorption cavity ringdown spectroscopy by exciting radiocarbon-dioxide ((14)C(16)O(2)) molecules at the 4.5 μm wavelength. The ultimate sensitivity limits of molecular trace gas sensing are pushed down to attobar pressures using a comb-assisted absorption spectroscopy setup. Such a result rep...
