Applying System Dynamics To Confront Complex Decision Making In R&D Systems#11;#11;: A Knowledge Based Approach, Arash Golnam, Nader Ale Ebrahim
Applying System Dynamics To Confront Complex Decision Making In R&D Systems#11;#11;: A Knowledge Based Approach, Arash Golnam, Nader Ale Ebrahim
Nader Ale Ebrahim
Research and development has always played a strategically important role in the survival and the growth of technology-based firms. R&D is positively linked to company performance measures such as sales, productivity and shareholder returns and in addition to this, facing increased competition, as a result of globalization the viability of many established firms is based on the efficiency of their R&D activities. Similar to other business models, R&D systems are characterized by complex structure and dynamic behavior. It's often difficult to predict or trace the consequences of certain decisions due to the existence of delays, non-linearities and causal feedback inherent …

Backend Framework And Software Approach To Compute Earthquake Parameters From Signals Recorded By Seismic Instrumentation System, Raman Attri
Raman K. Attri
Computation of seismic parameters and its interpretation from the recorded earthquake signal is empowered by digital data acquisition systems. This enables seismologist to automatically compute all the relevant parameters. Futuristic applications require extensive software development to implement seismic prediction and forecasting models. While developing such models, software developer prefer to write their own in-house analysis & modeling software with complete control over the required computations and models. This paper presents simplified mathematical framework of the seismic events and back-end computational software logic & algorithm to provide a simple framework to software engineers develop customized seismic analysis & computation software.

n recent years, along with the trend toward clean air and less dependency to imported oil products, there has been increasing willing to use substitute fuels in transport industry. Automobile industry is an exhaustive industry bringing development for any country. The industrial capabilities needed for development rest in this branch of industry. The Iranian automobile making companies move in line with this aim. But in recent decades, in addition to development of automobile industry, the pollution too has occupied the minds of the authorities of these companies. Some measures, investments, researches, and exhaustive studies related to the pollution problem have …
Impact Of Interconnection Photovoltaic/Wind System With Utility On Their Reliability Using A Fuzzy Scheme, Dr. Adel A. Elbaset
Impact Of Interconnection Photovoltaic/Wind System With Utility On Their Reliability Using A Fuzzy Scheme, Dr. Adel A. Elbaset
Dr. Adel A. Elbaset
Reliability analysis has been considered as an important step in any system design process. a reliable electrical power system means that the system which having sufficient power to feed the load demand during a certain period or in other word, having small Loss of Load Probability (LOLP). LOLP is defined as an expected fraction of load not met by its needed power from electrical power system during its lifetime. Photovoltaic (PV) / Wind Energy System (WES) hybrid electric power system (PV/WES HEPS) differs considerably from the utility grid (UG) in their performance and operating characteristics. With the interconnection of PV/WES …
The Effect Of A Repetitive, Fatiguing Lifting Task On Horizontal Ground Reaction Forces, Yu Shu, Jonathan Drum, Stephanie Southard, Gwanseob Shin, Gary A. Mirka
The Effect Of A Repetitive, Fatiguing Lifting Task On Horizontal Ground Reaction Forces, Yu Shu, Jonathan Drum, Stephanie Southard, Gwanseob Shin, Gary A. Mirka
Gary A. Mirka
There are many outdoor work environments that involve the combination of repetitive, fatiguing lifting tasks and less-than-optimal footing (muddy/slippery ground surfaces). The focus of the current research was to evaluate the effects of lifting-induced fatigue of the low back extensors on lifting kinematics and ground reaction forces. Ten participants performed a repetitive lifting task over a period of 8 minutes. As they performed this task, the ground reaction forces and whole body kinematics were captured using a force platform and magnetic motion tracking system, respectively. Fatigue was verified in this experiment by documenting a decrease in the median frequency of …

The recent introduction of sessions dedicated to “Industrial Technology” in the annual ASEE conference is testimony that this discipline has gained its rightful place in the company of engineering and engineering technology. This new level of partnership and collaboration between engineering and technology programs promises to be a step in the right direction for society at large. Engineering and technology majors both supplement and complement each other’s knowledge and skills and it is crucial for educators to build bridges of active interaction. This paper takes aim at one specific as well as basic need in teamwork and interdisciplinary projects – …
Variability Of Residual Stresses And Superposition Effect In Multipass Grinding Of High-Carbon High-Chromium Steel, Olga Karabelchtchikova, Iris V. Rivero
Variability Of Residual Stresses And Superposition Effect In Multipass Grinding Of High-Carbon High-Chromium Steel, Olga Karabelchtchikova, Iris V. Rivero
Iris V. Rivero
The distribution of residual stresses (RS) and surface integrity generated in heat treatment and subsequent multipass grinding was investigated in this experimental study to examine the source of variability and the nature of the interactions of the experimental factors. A nested experimental design was implemented to (a) compare the sources of the RS variability, (b) to examine RS distribution and tensile peak location due to experimental factors, and (c) to analyze the superposition relationship in the RS distribution due to multipass grinding technique. To characterize the material responses, several techniques were used, including microstructural analysis, hardness-toughness and roughness examinations, and …
Characterization Of Changes In Electrophysiological Activity In An Operational Environment, Natalia Mazaeva, Santosh Mathan, Michael C. Dorneich, Stephen Whitlow, Patricia May Ververs
Characterization Of Changes In Electrophysiological Activity In An Operational Environment, Natalia Mazaeva, Santosh Mathan, Michael C. Dorneich, Stephen Whitlow, Patricia May Ververs

The purpose of this study is to characterize differences in EEG collected under stationary conditions and that collected in mobile settings. EEG activity has not been evaluated in operational settings due to difficulties associated with processing of EEG in real-world settings such as real-time removal of artifacts, operational environments, and possible differences in EEG frequency associated with mobility. Utilization of EEG measures of cognitive activity in dynamic environments demands the use of real-time algorithms of signal decontamination and characterization of specific components of EEG activity. In this study, EEG was collected and filtered in real-time in a set of controlled …

This paper takes aim at one specific, as well as basic, need in teamwork and interdisciplinary projects – ethics and its implications for professional practice. A preliminary study suggests that students majoring in industrial technology degree programs may not have adequate opportunity to formally study and engage in ethical aspects of technology vis-à-vis the practices of the profession. It is reasonable to assume that the ethical dilemmas faced by an industrial technologist would parallel those of engineers and managers. To address this issue, this paper identifies a domain of knowledge that would constitute a necessary background in ethics for industrial …
Cluster Treatment Of Characteristic Roots, Ctcr, A Unique Methodology For The Complete Robustness Analysis Of Linear Time Invariant Multiple Time Delay Systems Against Delay Uncertainties, Rifat Sipahi
Rifat Sipahi
Today, many high-tech applications such as simultaneous metal machining, neural networks, internet data congestion, population dynamics, chemical processes, formation flight problems, etc., appear in the form of multiple time delay systems (MTDS ). Due to the presence of delays, the stability of the dynamics is under question and needs to be addressed. In the last four decades, the stability analysis of the general class, Linear Time Invariant MTDS (LTI-MTDS), has been one of the challenging problems of the systems and control community, which originates from the complex stability analysis due to their infinite dimensionality. For tackling this, a unique procedure …
