Integration analysis of product decompositions

This paper describes a methodology for the analysis of product design decompositions. The technique is useful for developing an understanding of the "system engineering" needs which arise because of complex interactions between components of a design. This information can be used to define the product architecture and to organize the development teams. The method involves three steps: 1) decomposition of the system into elements, 2) documentation of the interactions between the elements, and 3) clustering the elements into architectural and team chunks. By using this approach, development teams can better understand the complex interactions within the system, thus simplifying the development process for large and complex projects. arranged in chunks. The choice of product architecture has broad implications for product performance, product change, product variety, and manufacturability. Product architecture is also strongly coupled to the firm's development capability, manufacturing specialties, and product strategy. Selecting the proper architecture of the product is an extremely influential decision which must be made during the concept development and system-level design phases of the project; the architecture defines the sub-systems upon which the team will work for the bulk of the development effort. In product development, analysis of the product decomposition provides valuable insight into the structure of the problem and the choice of architecture. The integration analysis presented in this paper considers the interactions which occur between the elements of the decomposition. The building blocks (called chunks) which result from integration analysis can be used to define the product architecture and to structure the development teams. Examples of architecture and team structure can be found in any highly engineered product. In the automobile industry, development programs include hundreds or thousands of team members. It would be impractical to design the entire vehicle at once (too complex); nor would it be possible to develop the thousands of components one at a time (too slow). The vehicle is decomposed into a few major systems: body, powertrain, chassis, interior, climate control, electrical, and trim. Each of these major systems is in turn decomposed into a large number of sub-systems, resulting in hundreds of interconnected pieces with names like: passenger restraint system, fuel delivery system, remote entry system, etc. Finally, these sub-systems are decomposed into component parts which are designed and tested individually and together. The decomposition of the vehicle into sub-systems and components facilitates the rapid development of the individual pieces, yet this strategy does not address the needs for integration of the components' functions during the development process.
Air traffic flow management at airports : a unified optimization approach

The cost of air traffic delays is well documented, and furthermore, it is known that the significant proportion of delays is incurred at airports. Much of the air traffic flow management literature focuses on traffic flows between airports in a network, and when studies have focused on optimizing airport operations, they have focused largely on a single aspect at a time. In this thesis, we fill an important gap in the literature by proposing unified approaches, on both strategic and tactical levels, to optimizing the traffic flowing through an airport. In particular, we consider the entirety of key problems faced at an airport: a) selecting a runway configuration sequence; b) determining the balance of arrivals and departures to be served; c) assigning flights to runways and determining their sequence; d) determining the gate-holding duration of departures and speedcontrol of arrivals; and e) routing flights to their assigned runway and onwards within the terminal area. In the first part, we propose an optimization approach to solve in a unified manner the strategic problems (a) and (b) above, which are addressed manually today, despite their importance. We extend the model to consider a group of neighboring airports where operations at different airports impact each other due to shared airspace. We then consider a more tactical, flight-by-flight, level of optimization, and present a novel approach to optimizing the entire Airport Operations Optimization Problem, made up of subproblems (a) - (e) above. Until present, these have been studied mainly in isolation, but we present a framework which is both unified and tractable, allowing the possibility of system-optimal solutions in a practical amount of time. Finally, we extend the models to consider the key uncertainties in a practical implementation of our methodologies, using robust and stochastic optimization. Notable uncertainties are the availability of runways for use, and flights' earliest possible touchdown/takeoff times. We then analyze the inherent trade-off between robustness and optimality. Computational experience using historic and manufactured datasets demonstrates that our approaches are computationally tractable in a practical sense, and could result in cost benefits of at least 10% over current practice.

The Effects of Patents on the Relationship between R&D Activities and Business Management Performance: Focus on South Korean Venture Companies

Today, innovation is achieved by challenging the existing paradigm through cross-field collaboration, and R&D innovation plays a particularly crucial role. This study analyzed the effects of R&D innovation activities on business management performance in South Korea and examined the role that patents play in various R&D innovation activities. Panel regression and moderating effect analyses were conducted on small- and medium-sized venture enterprises that undertook new technology projects over five years (2015–2019). The results showed that R&D innovation activities had a significantly positive effect on both revenue, an indicator of business growth, and operating profit, an indicator of profitability. This implies that such activities play a positive role in management activities. Thus, enterprises should consider R&D innovation activities from a business growth strategy perspective. Additionally, the analysis showed that a firm’s capacity to hold patents on R&D innovation activities has a positive moderating effect on business management performance. This study is significant, as it reveals the cause-and-effect relationship between R&D innovation actives and business management performance as well as the role of various types of innovation. The results could help enterprises to seamlessly implement innovation activities in the future.
Gear Fault Diagnosis Method Based on Cyclostationary Degree and HMM

This paper proposes a gear fault diagnosis method based on cyclostationary degree and Hidden Markov Model (HMM) theory. By using the demodulation characteristic of cyclostationary degree for AM and FM signals, we extract the characteristic information of the gear working status. This information can be converted into sets of fault feature vector, which is used as the training sample or observed sample of HMM model for gear fault identification. Experimental results show that the gear fault diagnosis method has good recognition result for the four kinds of status of normal, broken teeth, pitting and wear gear.
Development of a new laser Doppler velocimeter for the Ames High Reynolds Channel No. 2

A new two-channel laser Doppler velocimeter developed for the Ames High Reynolds Channel No. 2 is described. Design features required for the satisfactory operation of the optical system in the channel environment are discussed. Fiber optics are used to transmit the megahertz Doppler signal to the photodetectors located outside the channel pressure vessel, and provision is made to isolate the optical system from pressure and thermal strain effects. Computer-controlled scanning mirrors are used to position the laser beams in the channel flow. Techniques used to seed the flow with 0.5-micron-diam polystyrene spheres avoiding deposition on the test-section windows and porous boundary-layer removal panels are described. Preliminary results are presented with a discussion of several of the factors affecting accuracy.

Fuzzy approach to fault classification for transmission line protection

This paper presents a scheme for real time fault location and classification on transmission lines using fuzzy logic technique. The protection algorithm is based on the travelling waves present on major transmission lines after the incidence of a fault. The time interval between the initial travelling wave propagated from a fault and a later wave resulting from a reflection at the fault position is used to find the location of the fault. A possible application based on modal analysis to detect the type of fault is also proposed. This paper shows that a fuzzy approach can be useful in transmission line protection, whenever fuzzy decisions have to be undertaken. Simulation results are used to illustrate the basic features of the performance of the new scheme on a 220 kV transmission line.

MPLM On-Orbit Interface Dynamic Flexibility Modal Test

Now that the International Space Station (ISS) is being constructed, payload developers have to not only verify the Shuttle-to-payload interface, but also the interfaces their payload will have with the ISS. The Multi Purpose Logistic Module (MPLM) being designed and built by Alenia Spazio in Torino, Italy is one such payload. The MPLM is the primary carrier for the ISS Payload Racks, Re-supply Stowage Racks, and the Resupply Stowage Platforms to re-supply the ISS with food, water, experiments, maintenance equipment and etc. During the development of the MPLM there was no requirement for verification of the on-orbit interfaces with the ISS. When this oversight was discovered, all the dynamic test stands had already been disassembled. A method was needed that would not require an extensive testing stand and could be completed in a short amount of time. The residual flexibility testing technique was chosen. The residual flexibility modal testing method consists of measuring the free-free natural frequencies and mode shapes along with the interface frequency response functions (FRF's). Analytically, the residual flexibility method has been investigated in detail by, MacNeal, Martinez, Carne, and Miller, and Rubin, but has not been implemented extensively for model correlation due to difficulties in data acquisition. In recent years improvement of data acquisition equipment has made possible the implementation of the residual flexibility method as in Admire, Tinker, and Ivey, and Klosterman and Lemon. The residual flexibility modal testing technique is applicable to a structure with distinct points (DOF) of contact with its environment, such as the MPLM-to-Station interface through the Common Berthing Mechanism (CBM). The CBM is bolted to a flange on the forward cone of the MPLM. During the fixed base test (to verify Shuttle interfaces) some data was gathered on the forward cone panels. Even though there was some data on the forward cones, an additional modal test was performed to better characterize its behavior. The CBM mounting flange is the only remaining structure of the MPLM that no test data was available. This paper discusses the implementation of the residual flexibility modal testing technique on the CBM flange and the modal test of the forward cone panels.
Electronic student portfolios: documenting learning in grade 2/3

Capturing, documenting, assessing, and highlighting the dynamic nature of learning has challenged educators for decades. Student portfolios offer flexible and versatile options in meeting these goals. Rapid advances in technology have permitted and indeed, enticed educators in the exploration of electronic portfolios. Technology such as computers, scanners, digital cameras, CD writers, and the World Wide Web have expanded the possibilities in documenting student growth and learning. My qualitative study focuses on using electronic portfolios in my grade 2/3 class at Blackie School. Four students were selected to participate, with equal representation from males, females, grade 2, and grade 3. The participants compiled electronic portfolios to document their learning and growth throughout the school's second reporting period. The creation of the electronic portfolios took place over a six-week period in March and April 2001. Data was collected from my journal, observations, studentjoumals, student surveys, and parent surveys. From the data, two general conclusions emerged. Firstly, an electronic showcase portfolio or an electronic component within the traditional paper portfolio, may be more viable options for Division I (K-3) students. The time and challenges encountered in digitizing the volumes of paper samples necessary for an electronic process portfolio were enormous. Secondly, a robust computer network including a fileserver and peripherals are essential, as is technological support and training for educators. The computer system must be able to support the daily demands of the general school popUlation in addition to supporting massive multimedia files created by electronic portfolios. Indeed, technology can be incorporated into student portfolios, offering new avenues in documenting student
Experimental study on controlling wake vortex in water towing tank

An experimental study was carried out to establish a self-destructing vortex wake. Sets of horizontal tail plains were employed to generate additional vortex sheet interacting with the wing vortex sheet of a rectangular wing. The study was made in the water towing tank in Gottingen (WSG), which was instrumented with 2D/3C PIV system, balance and flow visualisation devices. The tailoring of 4 vortices wake systems was achieved by varying horizontal tail plains with different aspect ratios with various incidences, generating various destabilising effects. The study exhibited that the interaction of tail vortices with tip vortices may result in a promising self-destructive mechanism within the wake system in the sense that the vortex core experiences an instability and decay abruptly. Typically, the wake vortex cores could be destabilised by as early as in 30 wing spans downstream with suitable tail settings, instead of more than 100 wing spans for that of a "clean model". The possible influence from the finite movement in the water tank due to transient processes of the model (end-effect) was investigated. The influence of the bottom and side wall effects was estimated from comparison of results from a larger water towing tank (HSVA).
