An Investigation of Early Idea Development in Development Projects

Today, there is an uncertainty regarding idea development, and a lack of knowledge in the existing literature regarding early idea maturation in development projects has been found. While previous research within the area of innovation mainly investigating ideas within the Fuzzy Front End, this master thesis focus on the management of ideas in the early phases of development projects.This master thesis strives to map the current way of working with ideas and methods used to develop ideas in the beginning of product and knowledge development projects at Sandvik Coromant. The aim is to shed light upon the gap regarding early idea development, with the long-term objective to improve the management of ideas in the beginning of projects to foster innovation. Five larger projects, that have used facilitated idea generation workshops, were selected to be part of the study. Interviews and a validation workshop were conducted in order to examine the development of ideas early in the projects. The differences between rejected ideas and further developed ideas, the belief in, and the fate of rejected ideas in development projects were investigated.The findings showed that the maturation of rejected and further developed ideas occurs at different times of the projects, as well as in different core elements. Further, the result indicates that ideas aiming to solve sub-problem in development projects do not mature to the same extent in all core elements comparing to earlier research on maturation of product ideas. There were no differences found between rejected and further developed ideas regarding documentation and the spreading of ideas. Neither did the belief in an idea in the beginning of the projects differ between the rejected and the further developed ideas.

INTERFERENCE MODELIZATION IN MULTI-ROBOT AUCTION METHODS

Abstract Task allocation is one of the main problems in multi-robot systems, very specially when the robots form coalitions. To get a good task allocation, we have to take into account, among other factors, the interference effect or the interaction between robots. Interference is not easy to modelize because it depends on a lot of dynamic factors. This paper models the interference impact using auction methods and support vector regression. We will show how the performance of the auction utility function can be improved if the interference impact is included in it. This method has been tested using transport like tasks taking into account an specific interference called physical interference.

Sustainability as a Guide for Selecting and Prioritizing Seismic Retrofit

Insufficient physical performance of concrete bridges during natural hazards can have cascading social, environmental, and economic consequences. Such consequences are an indication of the inhibited sustainability of bridge infrastructure caused by hazards such as earthquake events. This paper frames the relationship between bridge performance in seismic events and metrics of sustainable performance, such as life-cycle cost, energy usage, or downtime. Overarching principles for sustainable bridges include evaluation of the three core pillars on sustainability (social, environmental, and economic impacts), consideration of lifetime performance, and integration of risk assessment principles. A risk-based approach is first presented in detail for evaluating retrofits for non-seismically designed bridges based on lifetime seismic life-cycle costs and cost-benefit analysis. A simple extension is provided for evaluating multiple sustainability metrics beyond economic impacts to prioritize bridges for seismic upgrade. This paper illustrates the critical link between mitigating seismic risks and promoting sustainable bridge infrastructure.
Unified Approach to Ship Seakeeping and Maneuvering by a RANSE Method

In this work, a computational procedure for the prediction o f motion of rigid bodies floating in viscous fluids and subjected to currents and waves is presented. The procedure is based on a coupled iterative solution of the equations of mot ion f a rigid body with up to six Degrees Of Freedom (DOF) and the Reynolds-Averaged NavierStokes Equations (RANSE) describing the turbulent fluid flow. The fluid flow is analyzed u sing a commercial CFD package (Comet) which can use moving grids made of arbitrary polyhedral cells and allows sliding interfaces between fixed and moving grid blocks. The computation of body motion is coupled to the CFD code via user-coding interfaces on the b asis of each iteration. A fullyimplicit predictor-corrector procedure is employed for th e calculation of body motion, taking advantage of the iterative nature of the fluid-flow solver. The method is used to compute the motion of floating bodies/sh ips subjected to waves, showing favorable agreement with experiments. Extension t o more complex ship maneuvering applications is further conducted, which requires m odeling of interaction of ship, its rudder(s) and its propeller(s). With the ship hull and the ru dder modeled geometrically and the propeller simulated by a body force model, turning circl e and Zigzag maneuvers are performed as examples and the comparison with measurements show promising agreement.
LOSS OF CONTACT AND TIME DELAY DYNAMICS OF MILLING PROCESSES

Title of Document: LOSS OF CONTACT AND TIME DELAY DYNAMICS OF MILLING PROCESSES Xinhua Long, Doctor of Philosophy, 2005 Directed By: Professor B. Balachandran Department of Mechanical Engineering Considering the feed motion, the dynamics of constant spindle speed (CSS) milling processes is described by a set of delay differential equations with periodic coefficients and a variable time delay associated with each cutting tooth. This model, which has been developed for the first time as a part of this dissertation, is used to study the dynamics and stability of the system. The semi-discretization scheme, a numerical scheme with an analytical basis, is refined to examine the stability of periodic solutions of this system. This scheme can be used to predict not only the stability but also the chatter frequencies for a wide variety of milling operations ranging from full-immersion to partial-immersion operations. From the results obtained thus far, it can be stated that feed-rate effects can be neglected during fullimmersion and high-immersion operations, where the influence of loss of contact nonlinearities is not pronounced. However, for low-immersion milling operations, where loss of contact effects have a strong influence on system stability behavior, high feed-rate effects are pronounced and this effects can’t be ignored. Along with investigations into the dynamics of CSS milling processes, in this dissertation, a better delay approximation has been used in the modeling of variable spindle speed (VSS) milling processes, and the benefits of VSS milling operations are discussed by comparing the stability charts of VSS milling operations with those obtained for CSS milling operations. The nonsmooth characteristics of milling processes are pointed out by presenting the simulated results for cutting forces. Work conducted with a nonsmooth mechanical system, a simplified system related to the milling process, is presented and the numerical results and experimental results obtained show evidence for grazing and other bifurcations in this nonsmooth system.

Evaluation of Self-Consolidating Concrete (SCC) for Use in North Dakota Transportation Projects

This research project was conducted to evaluate the plastic and hardened properties of self-consolidatilng concrete (SCC) as compared to conventional (normal) concrete (NC) mixes with the same mix proportions. A state department of transportation (DOT) survey was conducted on the present use of SCC in transportation structures. A total of six mixes were subjected to the testing program, including three NC and three SCC mixes. In particular, three pairs of mixes were compared on an individual basis and collectively as a group. For each pair of mixes the cementitious material, aggregate proportions, and water to cement ratio were held constant. Moreover, the water to cement ratio and the fine to total aggregate ratio were held constant for all mixes; the only parameters that could be varied were the admixture dosages. Many strength parameters were tested but properties such as bond strength, tensile strength, permeability, and air void structure were of high interest due to the variability of performance of SCC in past research. ASTM criteria were used to qualify SCC mixtures in the plastic state; namely the slump flow test, slump flow with J-Ring, and column segregation test. The final mix proportions used in this research represent the lower bound in terms of cementitious material used in practice today. It is expected that the results of this research along with the state DOT survey responses will aid the North Dakota DOT in writing its own specification for use of SCC in transportation infrastructure.
Hydrodynamic Forces on Inundated Bridge Decks

The hydrodynamic forces experienced by an inundated bridge deck have great importance in the design of bridges. Specifically, the drag force, lift force, and the moment acting on the bridge deck under various levels of inundation and a range of flow conditions influence the design and construction of the bridge. This report explores the forces acting on bridges in two ways. First, through physical experimentation on scaled-down bridge deck models tested in a flume and then with computational fluid dynamics (CFD) simulation models. Three bridge deck prototypes were used for the experimentation: a typical six-girder highway bridge deck, a three-girder deck, and a streamlined deck designed to better withstand the hydraulic forces. The forces (expressed as nondimensional force coefficients) on each of the bridge deck shapes were measured in the laboratory with an ultra-precise force balance under a range of inundation scenarios (including partial inundation) and at four different velocities characterized by Froude numbers in the range of 0.16 to 0.32. CFD modeling was performed using both the Fluent® and STAR-CD® software packages. The CFD models were calibrated to the flow conditions of the six-girder bridge, and these same conditions were used for the other two bridge shapes. A range of model options were tested including two-dimensional versus three-dimensional models, different mesh resolutions, boundary conditions, and turbulence models; their effect on the accuracy of results and processing efficiency were noted. Fitting equations were generated to create an envelope around the experimental data and create design charts for each of the bridge types and force coefficients. Finally, the CFD models, though they can match some of the general behavior of experimental models in terms of the relationship between inundation ratio and force measured at the bridge, do not yet faithfully reproduce the critical values of the hydraulic forces and show very little response to velocity. The CFD simulations seem promising as a method to test bridge designs, but more research is needed before complex designs can be tested wholly in the CFD realm. However, the design charts from the experimental results should be a valuable tool for the bridge designer in a wide range of design applications.
Selecting Bug-prone Components to Study the Effectiveness of Reengineering and Unit Testing:

Many software companies see their code grow into legacy code. Making changes to such code is risky, as existing functionality elsewhere can easily be broken. By reengineering the code and covering it with unit tests, the code can be brought back into a maintainable state. In this study we measure the effect of reengineering and unit testing code on the number of fixed bugs. We do so by comparing the predicted and actual number of bugs for a component, after reengineering and unit testing it. We predict the bug-proneness of components by mining the bug repository, and provide and evaluate an approach for selecting the most feasible components by including the estimated test effort. Initial results indicate that the number of bug fixes decreases after a bug-prone component has been reengineered and covered with unit tests. We conclude that our approach is able to predict the bug-proneness of components, and successfully ranks them by feasibility. But in order to formulate a final answer on the effectiveness, more data is needed.
The severity and effects of Cyber-breaches in SMEs: a machine learning approach

ABSTRACT In this paper, we investigate cyber breaches and their effects on small and medium enterprises (SMEs), considering the role that cybersecurity plays in SMEs, and the importance that SMEs have in the economy. Using the Cyber Security Breaches Survey data, the first contribution extends previous works confirming that SMEs receive a wide variety of breaches. Secondly, we have characterized the degree of severity of breaches in SMEs, based on disruption time and their cost. Our last contribution consists of determining the effect and severity of breaches in SMEs in terms of economic, financial and management impacts.
Rotorcraft Brownout Mitigation Through Flight path Optimization Using a High Fidelity Rotorcraft Simulation Model

Title of thesis: ROTORCRAFT BROWNOUT MITIGATION THROUGH FLIGHT PATH OPTIMIZATION USING A HIGH FIDELITY ROTORCRAFT SIMULATION MODEL Jillian Alfred, 2012 Thesis directed by: Professor Roberto Celi Department of Aerospace Engineering Brownout conditions often occur during approach, landing, and take off in arid climates and involve the entrainment of loose sediment and dust into the rotor flow field. Research into brownout mitigation through operational means such as flight management have presented significant steps forward in reaching possible methods, but the approaches include many simplifications and assumptions in modeling the rotorcraft, as well as the approach profiles. This thesis describes a rotorcraft brownout mitigation study through flight path optimization using a high fidelity rotorcraft model. A flight dynamics model was coupled to a free-vortex method (FVM) model and particle tracking model to more accurately calculate the aerodynamics of the rotor with a full rotorcraft model. In addition to the model coupling, an approach profile following method was developed for the time-integration to specify the path of the rotorcraft through space. An optimization study was then performed using this flight dynamics model in a comprehensive brownout simulation. The optimization found a local shallow optimum approach and a global steep optimum approach minimized the intensity of the resulting brownout clouds. These results confirmed previous mitigation studies and operational methods. The results also demonstrated that the addition of a full rotorcraft model into the brownout simulation changed the characteristics of the velocity field, and hence changing the characteristics of the brownout cloud is produced.

Comparing award methods: application in various countries

In the award phase of the tendering process, different award methods can be used. This can either be based on Lowest Price (LP) or one of the Most Economically Advantageous Tender (MEAT) methods. MEAT methods include, among many more, Weighted Factor Score (WFS) and Awarding on Value (AoV). AoV has been developed in the Netherlands to help avoid corruptive practices that have occurred in the past and stimulate innovation (JANSEN ET AL., 2007). The three methods were compared in an empirical study using a questionnaire that was distributed among purchasing professionals across the world. The attitudes towards the three methods were tested based on familiarity, whether they have been used before, likability and considered applicable. While the MEAT methods are better liked compared to LP, the latter is still been used more. We expect that is the case because legal restriction on using MEAT methods. In addition we tested whether Awarding on Value is considered to be more resistant to corruptive behaviour and the variables set for this in the requirements by the European Union. The respondents’ answers on perceived corruption prevention do not significantly confirm this. Also, no significant differences were found in this perception between the Netherlands and Africa.
Thermal Integrity Testing of Drilled Shafts

Drilled shaft foundations have historically been plagued with construction related defects (i.e., soil inclusions or poor concrete cover) that most often go undetected due to the blind construction techniques necessary. These defects can affect the quality of the bond interface between the shaft concrete and the insitu geomaterial as well as the durability of the reinforcement. This project investigated the merits of a new easy-to-use method of assuring shaft integrity via infrared thermal detection methods that can assess the presence or absence of intact concrete both outside and inside the shaft reinforcement cage. The objectives included (1) field temperature measurements of mass concrete structures with specific interest in drilled shafts and (2) numerical modeling to verify the anticipated temperature response within a drilled shaft or mass concrete structure. Both small scale and full scale shafts were constructed and monitored during the curing/hydration phase. The temperature measurements obtained were used to verify the presence of anomalies while also obtaining temperature dissipation information to the surrounding materials. These case studies were used to calibrate a 3-D thermal modeling software developed expressly for mass concrete conditions with emphasis on drilled shaft integrity evaluation. Further evaluation of these sites along with case studies from larger diameter shafts showed that mass concrete conditions could be experienced by shafts even when small in diameter. Using the new thermal modeling software, the physical dimension of the test shafts as well as the location of known anomalies were inputted and signal matched against the measured temperature traces. The good correlation obtained showed that forward modeling shafts could be used to predict the size and location of anomalies. Inverse modeling algorithms were also developed with encouraging results. Finally, prospective construction techniques using voided shafts were conceived, modeled, and evaluated for feasibility. Initial results indicate that benefits could be derived from both mass concrete temperature control and reduction in concrete volume/usage.
Data Communications Segment 2 Airport Traffic Control Tower Human-in-the-Loop Simulation.

This technical report provides a brief literature review of previous research on air traffic control concepts relevant to the Data Communications (Data Comm) program and examines the use of digital-taxi (D-Taxi) clearances for departure aircraft under three levels of data link equipage (Voice Only vs. 40% Data Comm vs. 75% Data Comm). Sixteen current controllers participated in a high-fidelity, human-in-the-loop simulation to assess the potential effects of D-Taxi on controller communications, workload, and performance. The authors collected measures of airport system efficiency and usability measures for the Tower Operations Digital Data System that enabled the D-Taxi functions and taxiway conformance monitoring. The authors examined the specific effects of taxi conformance monitoring and a complete data link system failure in an additional exploratory scenario. This report provides a detailed set of results and recommendations for future research and requirements generation that the Federal Aviation Administration should consider when implementing the Data Comm Segment 2 concepts.
