A successful lean implementation is the key for lean enterprise transformation. However, many companies are struggling to change the culture in their system and are having problems in adapting lean principles. In this article, we discuss whether lean standardization and professional lean certification (LS&C) has the potential to promote successful lean implementation leading to a lean enterprise transformation. For this purpose, we first analyzed the concepts of LS&C and reviewed the existing ones, including J4000 through literature review and personal communications with lean experts. We also conducted a survey among lean professionals to get feedback about their attitudes toward LS&C. The survey results suggest that there is significant support for LS&C, as around 60% of the survey attendants believe LS&C would eliminate problems in implementing lean principles. However, the awareness of existing standards among lean practitioners is very low, which indicates the need for development of new lean standards and/or better promotion. Our survey results also suggest that the level of support for lean standardization depends on many factors, including positions of the professionals and extent of companies’ lean experience. © IIE, INCOSE.

As an alternative to the conventional method, which length measurement is performed as a function of the wavelength of a monochromatic laser source, we proposed the method of measuring arbitrary and absolute length using the pulse repetition interval of a femtosecond optical frequency comb (FOFC - the national standard tool for measuring length in Japan). A helium-neon laser evaluation system was developed for distance determination comparison experiment and its uncertainty estimation was performed in order to validate the proposed method.

In this paper, a novel approach for commanding mobile robots using a probabilistic multistroke sketch interface is presented. Drawing from prior work in handwriting recognition, sketches are modeled as a variable duration hidden Markov model, where the distributions on the states and transitions are learned from training data. A forward search algorithm is used to find the most likely sketch given the observations on the strokes, interstrokes, and gestures. A heuristic is implemented to discourage breadth-first search behavior, and is shown to greatly reduce computation time while sacrificing little accuracy. To avoid recognition errors, the recognized sketch is displayed to the user for confirmation;a rejection prompts the algorithm to search for and display the next most likely sketch. Upon confirmation of the recognized sketch, the robot executes the appropriate behaviors. A set of experiments was conducted in which operators controlled a single mobile robot in an indoor search-and-identify mission. Operators performed two missions using the proposed sketch interface and two missions using a more conventional point-and-click interface. On average, missions conducted using sketch control were performed as well as those using the point-and-click interface, and results from user surveys indicate that more operators preferred using sketch control. © 2011 IEEE.

Optical tweezers are used for manipulation of micron-sized dielectric beads and cells. Some biological cells are vulnerable to photo damage if subjected to laser-based direct manipulation. In such cases, precise manipulation of these cells can be accomplished by using gripper formations made up of silica beads, which are actuated by optical tweezers. Manual indirect manipulation of cells using grippers made of optically trapped beads is a time consuming process or sometimes just impossible. This paper presents an approach for automated micromanipulation using gripper formations and heuristic based path planning for collision-free transport of biological cells. The objective of the developed planner is to transport target cells to their respective goal positions in the minimum time. we evaluated the performance of different gripper formations in terms of gripper stability, speed of transport, and required laser power using experiments. © 2012 IEEE.

Artificial bee colony (ABC) is an optimization algorithm inspired on the intelligent behavior of honey bee swarms. It is suitable to be applied when mathematical techniques are impractical or provide suboptimal solutions. As a population-based algorithm, the ABC suffers on large execution times specifically for embedded optimization problems with computational limitations. For that we propose a hardware parallel architecture of the opposition-based ABC algorithm (HPOABC) that facilitates the implementation in Field programmable Gate Arrays (FPGAs). Numerical simulations using four well-known benchmark problems demonstrate that the opposition-based approach allows the algorithm to improve its functionality, preserving the swarm diversity. Additionally, synthesis results point outs that the HPOABC architecture is effectively mapped in hardware and is suitable for embedded applications. © 2012 IEEE.

Differential Evolution (DE) is a simple and efficient stochastic global optimization algorithm of evolutionary computation field, which involves the evolution of a population of solutions using operators such as mutation, crossover, and selection. The basic idea of DE is to adapt the search during the evolutionary process. At the start of the evolution, the perturbations are large since parent populations are far away from each other. As the evolutionary process matures, the population converges to a small region and the perturbations adaptively become small. DE approaches have been successfully applied to solve a wide range of optimization problems. In this paper, the parameters set of the Jiles-Atherton vector hysteresis model is obtained with an approach based on modified Differential Evolution (MDE) approaches using generation-varying control parameters based on generation of random numbers with uniform distribution. Several evaluated MDE approaches perform better than the classical DE methods and a genetic algorithm approach in terms of the quality and stability of the final solutions in optimization of vector Jiles-Atherton vector hysteresis model from a workbench containing a rotational single sheet tester. © 2011 Elsevier Ltd.

Granular media (GM) present locomotor challenges for terrestrial and extraterrestrial devices because they can flow and solidify in response to localized intrusion of wheels, limbs, and bodies. While the development of airplanes and submarines is aided by understanding of hydrodynamics, fundamental theory does not yet exist to describe the complex interactions of locomotors with GM. In this paper, we use experimental, computational, and theoretical approaches to develop a terramechanics for bio-inspired locomotion in granular environments. We use a fluidized bed to prepare GM with a desired global packing fraction, and use empirical force measurements and the Discrete Element Method (DEM) to elucidate interaction mechanics during locomotion-relevant intrusions in GM such as vertical penetration and horizontal drag. We develop a resistive force theory (RFT) to account for more complex intrusions. We use these force models to understand the locomotor performance of two bio-inspired robots moving on and within GM. © ASCE 2012.

A new scheme for designing a spatial light source for depth direction coherence control is proposed. This method is based on a combination of spatial coherence phenomena and the superposition principle. A computer-generated light source is projected onto a moving diffuser in order to realize multiple coherence peaks in the depth direction by synthesizing the longitudinal coherence function. Using this light source, we can shape a coherence function with multiple peaks, which are equidistant and have different strengths for distinguishability. This method may provide a new way of performing long-range depth direction measurements.
