A Field Experiment of Roadway Recognition and Data Transmission by Roadside Sensors for Autonomous Mobility Assistance System (AMAS)

Research and development (R&D) of an autonomous and automatic mobility assistance system (AMAS) in cooperation with the information communication technology (ICT) are undergoing. R&D of a technique to efficiently update and distribute dynamic map (DM), which is a database of the roadway information collected and analyzed by autonomous mobilities and roadside sensors, enables highly reliable and accurate automatic driving and automatic mobility control. For the verification of updating and distributing DM to autonomous mobilities, we developed a testbed system that acquires roadway information using roadside sensors namely wireless electronic traffic mirrors (WETMs), recognizes road objects and changes by the object recognition operations, and transfers the recognition information via a wireless communication system. In addition, we have implemented a method to drastically reduce the communication load by compressing the image information obtained from the roadside sensors, and verified it from the field experiments using the test-bed system.
Can We Measure and Communicate the Benefits of Work-Life Policies more Effectively

The current paper reviews twenty one different studies of work-life programmes drawn from articles published in a range of academic and management journals and promotional documents aimed at businesses. The review was interested to find out if the use of control groups, or other rigorous forms of measurement techniques have become more widespread. The review also highlights those studies that make a contribution by developing an interdisciplinary framework or made an effort to disseminate findings in a bilingual format. On the basis of the review, the paper finds that recent studies have used one of five different research designs to measure and evaluate the impact of work -life practices. The designs included; multivariate modelling; control groups; action research; business case calculations; and social surveys. The paper concludes that there has not been a wider application of control group methods. There is also evidence that the 'action research' approach is leading the path toward a more inter-disciplinary understanding of work-life conflict.
The design charts by waveguide model and mode-matching techniques of microstrip line taper shapes for Klopfenstein and Hecken type microstripline tapers

The optimum shapes in which the reflected wave decreases at a specific frequency for satellite broadcast reception were considered with the Klopfenstein and Hecken tapers. The tapered parts were divided like a flight of stairs. The scattering coefficients of each step were combined by using both the mode-matching and generalizing scattering methods. The /spl lambda//4 transformer changes to the Klopfenstein taper shapes, and the exponential taper changes to the Hecken taper shapes, when a longer length is used in the wide passband frequency. By choosing the parameters adequately, it becomes possible to choose the appropriate proportioned necessary bandwidth. This paper shows the practical designs for optimum shapes were obtained by using the Klopfenstein and Hecken tapers when the reflected wave decreases at a specific frequency for satellite broadcast reception.
High-Speed Solid-Rotor Induction Machine – Electromagnetic Calculation and Design

Thesis for the degree of Doctor of Science (Technology) to be presented with due permission for public examination and criticism in the Auditorium 1382 at Within the latest decade high-speed motor technology has been increasingly commonly applied within the range of medium and large power. More particularly, applications like such involved with gas movement and compression seem to be the most important area in which high-speed machines are used. In manufacturing the induction motor rotor core of one single piece of steel it is possible to achieve an extremely rigid rotor construction for the high-speed motor. In a mechanical sense, the solid rotor may be the best possible rotor construction. Unfortunately, the electromagnetic properties of a solid rotor are poorer than the properties of the traditional laminated rotor of an induction motor. This thesis analyses methods for improving the electromagnetic properties of a solid-rotor induction machine. The slip of the solid rotor is reduced notably if the solid rotor is axially slitted. The slitting patterns of the solid rotor are examined. It is shown how the slitting parameters affect the produced torque. Methods for decreasing the harmonic eddy currents on the surface of the rotor are also examined. The motivation for this is to improve the efficiency of the motor to reach the efficiency standard of a laminated rotor induction motor. To carry out these research tasks the finite element analysis is used. An analytical calculation of solid rotors based on the multi-layer transfer-matrix method is developed especially for the calculation of axially slitted solid rotors equipped with well-conducting end rings. The calculation results are verified by using the finite element analysis and laboratory measurements. The prototype motors of 250 – 300 kW and 140 Hz were tested to verify the results. Utilization factor data are given for several other prototypes the largest of which delivers 1000 kW at 12000 min-1. Graduate School of Electrical Engineering is greatly acknowledged. Most of all, to Maiju, Samuli and Julius: Your simple child's enthusiasm and your laugh gave me strength and kept me smiling. I am indebted to Saila for her love and patience during the years. Finally, my dear friends, without your warm support, endless patience and belief I would never have roamed this far.
Design of Guidance Law for Homing Missile Via Feedback Linearization

This paper examines tlhe guidance problem of an acceleration constrained homing missile when the initial missile heading is far lfrom intercept course. A representation of the kinematics and dynamics is first presented in which the system is affine in the missile's acceleration. A guidance strategy is then synthesized for the control of the feedba,ck linearized system. The implementation of the feedback linearized guidance law is discussed, and simulation results are given comparing miss distance performance of the feedback linearized guidance law to Proportionall Navigation. The simulations reveal that the feedback linauized guidance law performs approximately equal to or better than Proportional Navigation for all initial launch regions.
Fabrication process changes for performance improvement of an RF MEMS resonator : conformable contact lithography, Moiré alignment, and chlorine dry etching

Abstract : This thesis presents fabrication process improvements for a RP MEMS resonator for the purpose of improving the quality factor (Q) and extending the frequency range. The process changes include the use of conformable contact lithography (CCL) and chlorine-based dry etching for improved fine-feature patterning and moire-based alignment techniques to allow for a non-self-aligned process. The resulting control over feature size and structure are expected to improve Q and enable higher frequency resonators. A CCL process utilizing moire alignment marks is described. An automated moire-based alignment system using Labview software is presented which demonstrates sub-100 nm alignment accuracy for a single alignment mark. A full-water alignment experiment is described that demonstrates average pattern placement errors of \ 0.187 micrometers \ and \ 0.296 micrometers \ for the x and y directions respectively. The experimental limitations are analyzed and suggested improvements to the system are detailed.

Artificial intelligent speed control strategies for permanent magnet DC motor drives

The paper presents a prototype laboratory implementation and control system validation for two artificial intelligence (AI) based speed control strategies to be used with the permanent magnet (PM) DC motor drives. These two AI strategies include a fuzzy logic based controller (FLC) and an online tunable artificial neural network (ANN) based controller. The use of these two AI based speed controllers is motivated by motor drive system parameter uncertainties and the unknown nonlinear mechanical load characteristics over the extended range of operating conditions. The experimental results validate the good dynamic speed tracking performance of the two proposed speed controllers. Since the controlled motor drive system precise parameter values are not required in the control system implementation, the controlled motor drive system is robust and insensitive to the system parameters, load excursions, and operating condition changes. <<ETX>>
Predictors of second language English lexical recognition: Further insights from a large database of second language lexical decision times

In this study we analyze a large database of lexical decision times for English content words made by speakers of English as an additional language residing in the United States. Our first goal was to test whether the use of statistical measures better able to model variation associated with participants and items would replicate findings of a previous analysis of this data (Berger, Crossley, & Skalicky, 2019). Our second goal was to determine whether variables related to experiences using and learning English would interact with linguistic features of the target words. Results from our statistical analysis suggest affirmative answers to both of these questions. First, our results included significant effects for linguistic features related to contextual diversity and contextual distinctiveness, providing a replication of findings from the original study in that words appearing in more textual and lexical contexts were responded to quicker. Second, a measure of length of English learning and a measure of daily English use interacted with a measure of orthographic similarity. Our study provides further evidence regarding how a large, crowdsourced database can be used to obtain a better understanding of second language lexical recognition behavior and provides suggestions for further research.
A self-aligned STI process integration for low cost and highly reliable 1 Gbit flash memories

This paper describes a self-aligned Shallow Trench Isolation (STI) process integration to realize a low cost and high reliability 1 Gbit NAND flash memory. Peripheral low voltage CMOS transistors, high voltage transistors and small 5F/sup 2/ memory cells can be fabricated at the same time by using the self-aligned STI process. The advantages are as follows. (1) The number of process steps is reduced to 60% in comparison with a conventional process. (2) a high reliability of the gate oxide is realized even for high voltage transistors because the gate electrode does not overlap the trench corner. (3) A tight distribution of the threshold voltages (2.0 V) in a 2 Mbit memory cell array is achieved due to a good uniformity of the channel width in the self-aligned STI cells. Therefore this process integration combines a low cost with a high reliability for a manufacturable 1 Gbit flash memory.
A current-controlled variable-inductor for high frequency resonant power circuits

The practicality of designing a bias-controlled inductor, suitable for high frequency resonant mode inverters and converters, was investigated theoretically and experimentally. The proposed variable inductor is built around a double 'E' core structure with zero mutual coupling between the main inductor windings and the bias windings. The theoretical analysis of this study lead to a simple equivalent circuit and closed form equations that express the relationship between the inductance and the controlling bias current. Excellent agreement was found between model predictions and experimental results. <<ETX>>
Application of the Artificial Neural Network and Neuro‐fuzzy System for Assessment of Groundwater Quality

One of the most important aspects of the evaluation of any aquatic system is the simulation of water quality parameters. Recently, artificial intelligence methods have been broadly applied to simulate hydrological processes. This study evaluates the potential of applying the neuro-fuzzy system and neural network to simulate total dissolved solid and electrical conductivity levels, by employing the values of other existing water quality parameters. Consideration of these results will be important for implementing and adopting a water quality prediction model which is able to provide a useful tool for the management of water resources. In this study, water quality data were analyzed from five sampling stations over six years from 2008 to 2013, in the Langat Basin, Malaysia. An assessment of the model's performance was carried out through the correlation coefficient and mean squared error obtained from the model computation and measurement values of the dependent variables. Consequently, a close agreement between these values and their respective measured values in the quality of the groundwater were found. Accordingly, artificial intelligence approaches and adaptive neuro-fuzzy inference system models in particular are capable of interpreting the behavior of water quality parameters.
Multi-Modal Route Recommender System for Bangkok Public Transportation

Currently, Bangkok has a 151 kilometers service of a rail line, whereas the total plan is 540 kilometers. More rail lines are now under construction and supposed to be done by a few years. Regarding a massive public transportation network, we need a route recommender system to make traveling more efficient. This paper proposes the route recommender system which supports multi modes of transportation in Bangkok, including BTS, MRT, ARL, BMTA bus, and Chaophraya Riverboat. Users can see suggested routes and sort routes by travel time, fare, number of transfer, and overall score. The A* algorithm with the Haversine formula as the heuristic function is used to calculate the possible routes. Then the best route is selected based on the score, which is calculated form four factors: travel time, fare, number of transfer, and distance. The database contains 13,510 stops, and the results show that the system can suggest accurate routes within a few seconds, which is fast enough for all use cases and achieved overall user satisfaction at 84.8% from our user experience survey.

High speed sensorless fuzzy-like Luenberger observer

This paper presents a new method based on the Luenberger observer to estimate the flux and the speed of an induction motor. The method uses different values of the discrete observer matrix computed offline at different speeds in order to keep the poles inside the stability region. As the motor speed changes, the proper observer matrix is selected by the control system: in this way, the dynamic response and the stability of the observer are guaranteed at high speed as well as at low speed. The performance of a 4-pole induction motor drive, using the proposed observer, has been tested. Experimental results are shown up to 12,000 RPM.
A new value stream mapping approach for healthcare environments

Hospitals worldwide are giving a growing emphasis to the application of lean concepts in the healthcare sector, commonly known as ‘lean healthcare’. A fundamental tool that allows such implementations is the value stream mapping (VSM). The problem is that VSM models used in implementations of lean healthcare are simple adaptations of the original VSM model, which was initially directed towards manufacturing and may not always represent important support activities for the patient flow that directly impact treatment time. Within this context, this paper presents a new VSM approach for healthcare environments. This new VSM model, specifically designed for healthcare environments, contemplates all activities that directly affect the treatment time. In addition, the present paper also presents an action research in a Brazilian hospital where the proposed VSM model is compared to other VSM models found in the literature. The results shown that the proposed VSM model was able to identify some operational bottlenecks and wastes that interfere in the patient’s treatment that could not be identified by other mapping models studied.
Investigating the irregularity of bus routes: Highlighting how underlying assumptions of bus models impact the regularity results

A bus route is inherently unstable: in presence of traffic or for high passenger demands, buses fail to maintain their time-headways and so tend to bunch when the system is uncontrolled. Several bus motion models have been proposed to study the behavior of buses and evaluate regulation strategies. The ability of these models to reproduce the irregularity of bus systems comes only from stochasticity. Some recognized phenomena like a change of conditions during a day or delays at signalized intersections are ignored. This paper tries to fill this lack and provides an overview of existing dynamic bus-focused models. In a first time, commonly used deterministic and stochastic models are compared. That allows quantifying the relative influence of stochasticity of each model component on the regularity. Besides, previous works always consider routes in stationary conditions and assume that perturbations come only from stochasticity. Conversely, we show that a change of the system equilibrium leads to bus irregularity. Finally, this paper points out the inability of classical bus models to reproduce the effects of traffic signals. A refinement of travel time models is proposed to account for non- dynamic signals. Such a development could allow forecasting the bus route state in the case of Bus Rapid Transit.
Measured distribution of electric field in GTEM-cell

The electric field inside the GTEM-cell was measured with the field probe. The variation of the electric field was within 3 dB. The measured results were compared with the numerical model performed with finite element method (FEM). There is a very good agreement between measured results and the computer model. Both results prove that almost 80% of the area below septum could be used for testing purposes.
Blast Environment from Fully and Partially Vented Explosions in Cubicles

Abstract : Charges of cast cylinders of composition B explosive were detonated inside several small-scale 3- and 4-wall cubicles of different shape and size to establish methods and criteria for predicting the blast environment (positive and negative pressures, durations, and impluses) in and around cubicles containing fully and partially vented explosions. The blast environment was measured (1) inside the cubicle and (2) outside the cubicle behind the front wall, sidewalls, and rear wall at scaled distances. The blast environment was found to depend on the charge-to-volume ratio, scaled degree of venting, scaled vent area, and scaled distance. Design charts are presented for calculating the pressure-time loading in and around a cubicle for a wide range of these parameters. The procedures offer, for the first time, a rational procedure for tailoring the cubicle configuration and dimensions to the site requirements since it relates blast environment to cubicle parameters and charge weight. Some of the 3-wall cubicles had roofs and some did not. Adding a roof did not substantially reduce the blast environment at large-scaled distances. The greatest benefit from the roof was in the area close to the cubicle where the roof dramatically reduced the blast environment behind the backwall. Criteria is proposed for design loading in and around fully and partially vented cubicles.
An evaluation of routing policies for order-picking operations in low-level picker-to-part system

This paper evaluates the performance of three routing policies in the order-picking process, i.e. return, traversal, and midpoint policy. It is assumed that items are assigned to storage locations on the basis of the cube-per-order index (COI) rule in a low-level picker-to-part warehousing system. First, for the three policies, analytical models are developed for the total expected travel distance of the order picker considering the number of the stocking aisles is even or odd. Then the developed models are compared with simulation results to show the validity. Finally, the performance of the three policies is examined by varying the parameter value of the COI-based ABC curve, number of picks in the pick list, and ratio of the length to the width of the warehouse.
Predicting Low Temperature Engine Oil Pumpability with the Mini-Rotary Viscometer

A new viscometer, the mini-rotary viscometer (MRV), has been demonstrated to predict the low temperature pumpability performance of engine oils. This bench test method was developed at the request of SAE Fuels and Lubricants Subcommittee 2 and culminates a two-part ASTM Program to (1) define pumpability characteristics of reference oils in engines and (2) assess/develop bench test methods for predicting low temperature engine pumpability. The MRV is a low shear stress/shear rate viscometer that correlates either with an "average" engine or an individual engine, depending upon the critical rheological requirements of the particular engine or engines, and attains its high degree of correlation by predicting either of two failure modes -- air binding of the pump or insufficient oil flow rate to the oil pump inlet. Thus, the MRV complements the cold cranking simulator, a high shear stress device, in defining the low temperature behavior of straight-grade and multigrade engine oils.
