Simulation of Overlapping Design Activities in Concurrent Engineering

Concurrent engineering is the process of reducing the total project delivery time by overlapping activities that normally occur sequentially. The benefits are a shortening of delivery time and a possible reduction in overall costs. However, there are potential risks to overlapping dependent activities. The interaction between an upstream activity and a downstream activity relies on how information evolves in the upstream activity and how sensitive the downstream activity is to that changing information. This implies that if an upstream activity is slow to evolve information and a downstream activity is highly sensitive to changing information, the risk in overlapping these activities will be higher than activities that are fast to evolve and not as sensitive to changing information. The risk can manifest in rework, or reperforming some aspect of the downstream activity because of the evolution of the upstream activity and the amount of overlapping used. This research developed computer simulation models to better understand the potential risk of rework. The simulation models allow for overlapping different types of slow- and fast-evolving upstream activities with high- and low-sensitivity downstream activities using overdesign and early release strategies and different amounts of overlapping. The overall findings show that simulations of overlapping activities yield a reliable approach to modeling concurrent engineering activities. The simulations provide information on the probability of rework based on the different combinations of evolution, sensitivity, overlapping strategy, and the percent amount of overlapping used between the upstream and downstream activity. The use of computer simulations and modeling of overlapping activities therefore allows engineers and managers to understand the potential risks and what strategies to apply when utilizing concurrent engineering on a project.
Simulation-based adaptative toolpath generation in milling processes

Milling toolpath is often designed according to a CAD model which is not always an accurate representation of the real part. In an industrial framework, a significant geometrical variability is sometimes observed in parts that belong to the same batch. Therefore, the conventional approach making use of a unique nominal toolpath for manufacturing series of parts fails to confer both geometrical and dimensional conformity to the machined parts. This study explores a strategy for adapting on-line the toolpath thanks to measurements and data driven simulation. An approximation for the actual geometry is derived from data acquisitions and the path is adjusted accordingly. The POD snapshots technique is employed for building up a reduced basis of approximation by considering geometrical features as well as additional parameters (initial setup) for the part. Thanks to its filtering properties, that basis proves to be robust with respect to measurement noise.
ANALYSIS OF THE IMPACT OF MINDFULNESS ON QUALITY OF LIFE IN PATIENTS WITH MULTIPLE SCLEROSIS: SYSTEMATIC REVIEW

This study aimed to investigate the impact of the mindfulness-based interventions program on the quality of life of patients with Multiple Sclerosis. A systematic review was carried out based on the PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-Analyzes). For an updated perspective on the topic, the selected articles were published from March 2014 to March 2019. Thus, 10 articles were included in the review and were thoroughly compared. A detailed assessment was carried out to measure the impact of the mindfulness protocol both on the general quality of life and on its specific domains. It can be observed that there is some homogeneity of the results regarding the benefits of the practice of mindfulness in the patients’ general quality of life. Moreover, there was greater evidence of the effects of meditative practice on the psychological domain when compared to the physical domain. Hence, the present study considers the mindfulness program a viable tool to address quality of life in patients with Multiple Sclerosis. The lack of Brazilian studies in the area is highlighted. Also, further studies to evaluate the practice of mindfulness continuously, such as cohort studies, are necessary to elucidate the long-term effects of the protocol.
Improving Energy Efficiency of Smart Household Appliances and Devices

With the ever-increasing volume of applications of various kinds of electric drives in all spheres of human activity, the issues in improving the efficiency of the electromechanical converters of electric energy, one of the most important components of the electric drive (ED), are becoming increasingly important. Such issues include reducing their weight and size, improving the functional characteristics of these devices to increase their operational life and reducing the cost of manufacture. Taking full advantage of these opportunities relates to the AC and DC single-phase commutator motor (SCM), which is widely used in regulated and high-speed motor drives in home appliances and electric hand tools. The SCM is used in machinery where the load torque has a hyperbolic dependence on the rotational speed and the need to work with a large motor overload due to the “soft” mechanical characteristics of such motors.
Investigation of cross-field wavefront aberrations of KrF lithography exposure systems as a function of excimer laser bandwidth

Quantification of projection lens aberrations in lithographic exposure systems has gained significant importance due to more stringent critical dimension control and image fidelity requirements. As linewidths shrink, the impacts of wavefront aberrations on imaging become more pronounced. Therefore, minimization of the wavefront aberrations across the image field is desired and has led to the development of a number of measurement approaches. The proposed techniques have been evaluated extensively for characterization and specification of lens systems, adjustments, matching, and periodic control and monitoring of lithography systems for volume production. In this study, we discuss the contribution of excimer laser bandwidth towards lens aberrations. We carry out simulations of the effects of image contrast on conventional projection patterning, to evaluate the degree of aberation-induced linewidth changes depending on image contrast level. Also, experiments have been conducted to measure the response of wavefront error as a function of spectral bandwidth for a 0.6NA stepper and scanner. Depending on the field location, a positive relationship is observed between the measured aberration level and bandwidth. We propose a formalism to correlate the aberration measurement with aberration response to wavelength offset, presented elsewhere. [2] The wavefront error, in this work, is measured using a commercially available in-situ interferometric technique, whose response is largely insensitive to focal plane changes and partial coherence.

Sexual harassment and assault during deployment: Associations with treatment outcomes among Veterans with co-occurring PTSD and SUD

ABSTRACT Sexual trauma is common and increases the risk for posttraumatic stress disorder (PTSD), substance-use disorders (SUD), and depression among Veterans. Limited research has examined the impact of sexual harassment and assault during deployment on treatment outcomes among Veterans with co-occurring PTSD and SUD. The current study examined the frequency of exposure to sexual harassment and assault during deployment as a predictor of treatment outcomes among a primarily male sample of US military Veterans diagnosed with current PTSD and SUD. A secondary analysis was performed using data from a randomized clinical trial examining the efficacy of Concurrent Treatment of PTSD and Substance Use Disorders using Prolonged Exposure (COPE) compared to Relapse Prevention (RP). Data from 69 Veterans (91.3% male) who were deployed while in the service were analyzed using mixed models to determine whether frequency of exposure to sexual harassment and assault during deployment impacted changes in PTSD symptom severity, percent days using substances, and depressive symptoms during treatment. Over one-third of the sample (36.2%) reported exposure to sexual harassment and/or assault during deployment. Frequency of exposure to sexual harassment and assault during deployment was not a predictor of treatment outcome in any of the models, suggesting a similar response to treatment among those with varying frequency of exposure to sexual harassment and assault during deployment. Veterans with co-occurring PTSD and SUD who have been exposed to sexual harassment and assault during deployment may benefit from integrated trauma-focused treatments and treatments focused on decreasing SUD symptoms.
Double-directional channel measurements

The spatial mobile radio channel contains delay information and angular information about the multipath components (m.p.c.s.). Signal delay and ensuing intersymbol interference has played an important role since the inception of digital mobile radio systems like GSM. The multipath signals impinging from different directions of arrival (DOAs) at an antenna array received quite some attention in the past few years. We call this a directional channel. The investigation of smart antennas has lead to better understanding of the radio channel itself and to more accurate and realistic spatial channel models. The identification of useful m.p.c.s. and the suppression of undesired co-channel interference has great potential in smart antennas. The paper describes the use of a superresolution method to identify as many m.p.c.s. as possible. We offer also a novel solution to the "pairing problem", i.e. which DODs and DOAs match the underlying physical propagation path connecting them. Though the measurements we describe were made, for practical reasons, in predominantly static environments, we aim at mobile radio applications.
Size reduction and multi-resonance effects of slotted single-layer edge-fed patch antennas

In this work, easy to fabricate edge-fed, single-substrate, slotted, square-patch antennas were designed, fabricated, and measured. Effects of slots on patch antenna, such as the size reduction effect and the multi-resonance effect, are demonstrated by examples. Measurements show that up to four additional resonant frequencies below the original patch antenna’s TM020 frequency are obtainable and that the size of the antenna can be reduced to less than approximately 40% its original size. The size reduction property of the proposed antenna may be suitable for miniaturized planar and conformal antennas that are needed for personal communication devices, and the multifrequency property of the proposed antenna has the advantage of serving multiple frequencies with one antenna.
Analysis and simulation of conducted EMI generated by switched power converters: application to a voltage source inverter

This paper presents a frequency-domain analysis method for the calculation of conducted EMI disturbances produced by power electronic converters. Switched power converters have a singular behaviour from the EMC point of view. The complex geometry and the wide range of time constants involved, make the calculation of conducted disturbances a complex matter. The new modelling method presented here is based on a source-propagation path-derived disturbance"" simulation process and is specially designed to overcome the above mentioned problems. In the design of the proposed method quick and robust simulations were preferred rather than very accurate results. The features of the proposed method are shown in the paper by comparing simulation results with experimental results obtained in a general purpose three-phase voltage source inverter. ""
MITIGATING CONTRACTOR PROBLEMS EXPERIENCED IN THE CONSTRUCTION INDUSTRY OF TRINIDAD & TOBAGO

The construction industry of Trinidad and Tobago has been, for decades, a direct indicator of national development and contributor to economic growth. The associated problems of the industry as experienced by contractors negatively impacts project performance and success. This study identified the most common problems experienced by contractors and assessed these to determine their level of significance and importance to projects. Employing a survey questionnaire and analytical methods using the Statistical Package for the Social Sciences (SPSS), 43 problems were identified, classified into seven (7) factor groups: Financial, Managerial, Environmental, Labour Based, Resource Based Owner Based and Project Based that were ranked on their level of significance and importance. The top ten (10) problems were found to be delay of payments, design, scope and material changes, working in high risk areas, lack of feasibility and brief, corruption, lack of contractor’s experience, bureaucracy, geological problems, contractor’s finances and cash flow. These problems represent the Financial, Managerial, Environmental, Project Based and Owner Based factor groups with financial factors being the highest rated group of adverse effect and significance. Highlighting the findings of this study, the preferred solution to mitigate against the adverse impact indicative of the construction problems experienced were presented. These solutions can be implemented to reduce the adverse effects on projects, promoting sustainable construction practices in the construction industry of Trinidad & Tobago.
Development of a voice database to aid children with hearing impairments

In the development of software for voice analysis or training, for people with hearing impairments, a database having sounds of properly pronounced words is of paramount importance. This paper shows the advantage that will be obtained from getting an own voice database, rather than using those coming from other countries, even having the same language, in the development of speech training software aimed to people with hearing impairments. This database will be used by software developers at the School of Engineering of Mar del Plata National University.
Modeling Integrated Lane-Changing Behavior

The lane-changing model is an important component within microscopic traffic simulation tools. Following the emergence of these tools in recent years, interest in the development of more reliable lane-changing models has increased. Lane-changing behavior is also important in several other applications such as capacity analysis and safety studies. Lane-changing behavior is usually modeled in two steps: (a) the decision to consider a lane change, and (b) the decision to execute the lane change. In most models, lane changes are classified as either mandatory (MLC) or discretionary (DLC). MLC are performed when the driver must leave the current lane. DLC are performed to improve driving conditions. Gap acceptance models are used to model the execution of lane changes. The classification of lane changes as either mandatory or discretionary prohibits capturing trade-offs between these considerations. The result is a rigid behavioral structure that does not permit, for example, overtaking when mandatory considerations are active. Using these models within a microsimulator may result in unrealistic traffic flow characteristics. In addition, little empirical work has been done to rigorously estimate the parameters of lane-changing models. An integrated lane-changing model, which allows drivers to jointly consider mandatory and discretionary considerations, is presented. Parameters of the model are estimated with detailed vehicle trajectory data.
A Study on Data Pre-filtering Methods for Fault Diagnosis

High performance sensors and modern data logging technology with real-time telemetry facilitate system fault diagnosis in a very precise manner. Fault detection, isolation and identification in fault diagnosis systems are typical steps to analyze the root cause of failures. This systematic failure analysis provides not only useful clues to rectify the abnormal behaviors of a system, but also key information to redesign the current system for retrofit. The main barriers to effective failure analysis are: (i) the gathered data (event) logs are too large in general, and further (ii) they usually contain noise and redundant data that make precise analysis difficult. This paper therefore applies suitable pre-processing techniques to data reduction and feature extraction, and then converts the reduced data log into a new format of event sequence information. Finally the event sequence information is decoded to investigate the correlation between specific event patterns and various system faults. The efficiency of the developed pre-filtering procedure is examined with a terminal box data log of a marine diesel engine.
A Two-Dimensional Analytical Model for Tunnel Field Effect Transistor and Its Applications

In this paper, a two-dimensional analytical model for the tunnel field effect transistor (TFET) on the silicon-on-insulator substrate is proposed. The accurate electrostatic potential and electric field of the device are obtained by solving the Poisson equation with appropriate boundary conditions. The accuracy of the proposed analytical model is verified by comparing with numerical simulation. It is shown that the electrical behavior of the TFET is more properly described by defining the zero vertical electric field at the channel/buried oxide interface. Furthermore, this analytical model is extended to implement in the hetero-material-gate (HMG) TFET. The physical principle of the HMG TFET can also be depicted, and electrical properties are characterized using this model.
APPROACHES TO IMPROVE CrtI EXPRESSION IN RICE ENDOSPERM FOR INCREASING THE β-carotene CONTENT IN GOLDEN RICE

The invention of Golden Rice, which could produce β-carotene (provitamin A) in its endosperm, offered a new hope to improve diet of millions of people in the world. However, it is necessary to develop lines, which could produce a higher level of β-carotene than the existing golden rice lines to make Golden Rice possible for practical adoption. Working in this direction, we have modified the crtI gene, which encodes the bacterial carotene desaturase CrtI in the pathway of β-carotene synthesis by (a) replacing the CaMV35S promoter with an endosperm specific promoter, GluB1 or (b) using a synthetic crtI gene, which abolishes differences to the codon usage, met in genes for rice storage proteins driven by GluB1 promoter. With these new versions of the crtI gene, we obtained corresponding transgenic plants of which the resulting T1 rice grains were analyzed for carotenoid contents. Our data indicates that the approaches of modifying crtI gene did not directly result in an increase of β-carotene content in Golden Rice.
Direct Singular Positions of 3RPS Parallel Manipulators

In this study a procedure to obtain direct singular positions of a 3RPS parallel manipulator is presented. If the heights of 3 spherical joints, denoted by d1n , d2n , and d3n respectively, are used as coordinate axes, then the workspace of the moving platform may be represented as an inclined solid cylinder in this coordinate system. The location of a point on the solid circular cylinder determines a configuration of the manipulator’s moving platform. The procedure to locate direct singular positions consists of two steps, the orientation of the moving platform is assumed first, from which the horizontal position of the moving platform may be obtained; then in the second step the heights that make determinant of Jacobian matrix vanish may always be determined. Results show that unless the moving platform is normal to the base, in which case there exist only one or two singular configurations, otherwise there are always three singular configurations corresponding to a moving platform’s orientation.Copyright © 2004 by ASME
Kalman filtering based approach for light flicker evaluation of power systems

In this study, a Kalman filtering based approach is proposed to measure the light flicker of the electricity transmission systems. Analytical expressions of the instantaneous light flicker sensation are used to obtain a flicker estimation method based on the International Electrotechnical Commission (IEC) flickermeter. In the proposed method, the frequency domain components of the voltage waveform are obtained by Kalman filtering and these components are used to obtain the light flicker. The method is tested on both simulated data and field data obtained from three different electrical arc furnace (EAF) plants, where the flicker level is considerably high compared to other types of loads. The comparison of the results with the digital realisation of the IEC flickermeter shows that the method gives satisfactory estimations with low computational complexity. The method is especially useful for conditions such as disturbances and subsequent system transients where the system frequency deviates significantly. Since the frequency decomposition is obtained by using Kalman filtering, no leakage effect of the fast Fourier transform (FFT) method is involved in case of frequency deviations.
