One aspect that has mostly been overlooked in traditional economic lot-sizing is the implication of decisions on manual tasks and workload. Although lot-sizing decisions can have a significant impact on required manual material handling and on human performance, works that consider ergonomic aspects in lot-sizing are rare. This paper presents a model that integrates ergonomic aspect in terms of...

Transistor sizing is very important for determination of the circuit performance. As a result for providing fair evaluation, an optimal size of transistor is necessary. Genetic algorithm that is capable of reduction of search problem complexity uses the transistor sizing which is originally a kind of search problem in the large multidimensional search space for energy consumption optimization. ...

This study is devoted to discrete sizing optimization of truss structures employing an efficient discrete evolutionary meta-heuristic algorithm which uses the Newton gradient-based method as its updating scheme and it is named here as Newton Meta-heuristic Algorithm (NMA). In order to enable the NMA population-based meta-heuristic to effectively explore the discrete design space, a term contain...

Software companies exploit data about completed projects to estimate the development effort required for new projects. Software size is one of the most important information used to this end. However, different methods for sizing software exist and companies may require to migrate to a new method at a certain point. In this case, in order to exploit historical data they need to resize the past ...

Optical mapping is an integrated system for the analysis of single DNA molecules. It constructs restriction maps (noted as "optical map" ) from individual DNA molecules presented on surfaces after they are imaged by fluorescence microscopy. Because restriction digestion and fluorochrome staining are performed after molecules are mounted, resulting restriction fragments retain their order. Maps ...

ROSEN offers a combined inline inspection (ILI) service for Magnetic Flux Leakage (MFL) methodology and the Ultrasonic Testing (UT) with one inspection tool. These two methodologically independent measurements with one ILI run enable to supply a combined inspection service with many operational and qualitative benefits. The case study presented is based on a representative amount of high qualit...

An important challenge of grid control is the prediction of the frequency bias factor Ki so as to be as well matched to the actual frequency response characteristic βi of an area i as possible, in order to adhere to the principle of non-interaction in Secondary Control. In this report, new semi-online sizing methods based on extensive previous research and on the current operation policies in C...

the iranian ministry of energy commands the regional electrical companies to install dg resources at 63kv/20kv substations and at the end of 20kv lines. the first and foremost challenge in installing these resources is deciding on the optimal place and capacity of these resources. this paper is aimed to propose an appropriate algorithm for siting and sizing such resources in bakhtar regional el...

OBJECTIVE The objective of our study was to evaluate repeatability and reproducibility of lung nodule volume measurements using volumetric nodule-sizing software. MATERIALS AND METHODS Fifty nodules, less than 20 mm in diameter, in 29 patients were scanned with 1.25-mm collimation using MDCT (time 1 = T1). During the same session, two additional scans, using identical technique, were obtained...
