Abstract:
This dissertation explores the use of the efficiency performance measurement paradigm (EM), in terms of its concepts and applications, as an ex-ante mechanism to evaluate enterprise performance and inform enterprise design. The design of an enterprise is driven by decisions that include, but not limit to, which strategies to implement, how to allocate resources, how to shift operating patterns, and how to boost coordination among enterprises, among others. Up to date, EM has been mainly used as a descriptive mechanism, but the fundamental reason for measuring performance in an ex-post fashion, i.e., how well an enterprise does, is also valid in the context of design decisions, i.e., ex-ante evaluation. The contrast between the ex-post and ex-ante use of EM relates to the measurement purpose, i.e., why to measure. Ex-post measurement focuses on evaluating 'what happened' (non-disruptive) while ex-ante measurement emphasizes in informing design decisions exploring changes in current settings (more disruptive). Within this context and to achieve the purpose above, this dissertation is supported by theoretical insights and complemented with three empirical studies. The theoretical insights relate to facts that support, connect to, and challenge (i.e., facilitate or impede) the ex-ante use of EM for enterprise evaluation and informing enterprise design. Those insights are based on the efficiency performance measurement, organizational design and enterprise systems engineering literature. Meanwhile, the three empirical studies situate the application of EM as an ex-ante mechanism to inform evacuation management, bank branch management, and power plants. The theoretical and empirical results indicate that EM is well suited for both evaluating enterprise performance and informing design decisions. The main contribution of this dissertation to enterprise stakeholders is that EM can be not only used to answer how well the enterprise did, but also how well it could do if certain design decisions are taken.

Abstract:
Industrialised housing has increased its Swedish market share the latest ten years from 2% to 15%. Prefabrication has developed into actual industrialisation, where factories produce not only elements for site assembly, but takes wholesale responsibility for the sales, design, factory production, and assembly of houses. A higher automation in housing production puts demands on the design department to become more efficient. Design is identified as a bottleneck to further increase the production rate. Information deliveries are not produced in the needed rate. With the change from drafting to modelling in building design, opportunities are given to work simultaneously for better efficiency. The focus on BIM-supported CAD-tools has lead ICT-developers to create systems that mainly support product modelling. But, in industrialised housing, support for process efficiency is just as important.In a case study at a Swedish industrialised housing company, during a three year period, interviews, observations and design activities at the company were recorded to study what components and functionality in the design support create business value. The results show that by defining design in stages with gates, by parallel planning of activities, and by using process visualisation methods, the efficiency increased about 41 % in information deliveries. Furthermore, the use of support systems has to create both internal value for efficiency in information deliveries and external value to meet and handle client requirements in a standardised way. By releasing time from project management activities to improvements and product development the focus on the product could increase. Product development theories with axiomatic design as the foundation for a support system combines product structures with BIM functionality and process support for planning, which secures quality between disciplines in a concurrent approach. Product life cycle management (PLM) is an umbrella that manages product development in a life-cycle perspective trough a defined framework that is applicable to industrialised housing design, both for software developers and industrialised builders.
Industriellt byggande har de senaste tio åren ökat sina marknadsandelar från 2% till 15% på den svenska bostadsmarknaden för flerfamiljshus. Prefabricering har utvecklats till industrialisering, där fabriker inte bara producerar komponenter för montering på byggplats, utan tar även helhetsansvar för försäljning, konstruktion, i fabrik och för montering av bostäder. Utvecklingen av en mer automatiserad produktion ställer högre krav på projekteringen. Som en definierad flaskhals måste tid frigöras från koordinering till kärnverksamhet för att skapa förbättringar och tillåta produktutveckling. Med förändringen från ritningsbaserad till modellbaserad byggprojektering, ges möjligheten att arbeta samtidigt för bättre effektivitet. Fokuseringen på BIM-stöd med CAD-verktyg har lett till att utvecklare skapar system som i huvudsak stödjer produktmodellering. För industriellt bostadsbyggande, är stöd för effektivitet i projekteringsprocessen lika viktig. Empiri har samlats genom intervjuer, observationer och dokumenterade aktiviteter i en fallstudie hos en svensk industriell bostadsbyggare för att analysera vilka komponenter och funktioner som ett stödsystem för projektering behöver för att skapa värde för företagen. Resultaten visar att en definition av projektering i steg med gater, aktiviteter för samplanering och användandet av metoder för att visualisera processen har ökat effektiviteten med omkring 41 % för informationsleveranser. Dessutom visar studien att stödsystem bör kunna skapa både internt värde för effektiva informationsleveranser och yttre värde för att möta och hantera kunders krav på ett standardiserat sätt. Ett stödsystem, baserat på produktutvecklingsteorier med axiomatisk design som grund, kan kombinera både produktstruktur med BIM- funktioner och processrelaterade funktioner för planering och därmed säkra kvaliteten mellan discipliner för samverkande arbete. Product life cycle management (PLM) är ett övergripande koncept för hantering av produktutveckling i ett livscykelperspektiv, vilket har ett definierat regelverk som är applicerbart på industriell byggprojektering, både för utvecklare av IT-system och för industriella husbyggare.

Abstract:
Generators are widely used across the world as portable power units in case of power outages, used for emergency services and are also used in rural areas without access to electricity. The majority of commercially available generators use internal combustion engines designed as automobile engines with little or no optimization for use in generators. With operating conditions vastly different than that of automobile engines, they can be re-designed to operate much more efficiently as generator engines. The development objective here was to design a low cost, 1.6L, lean burn, internal combustion engine which minimizes heat losses, time losses and frictional losses to improve thermal efficiency. Various high swirl, high squish, easily CNC’d combustion chambers were created in the re-design process. A computer model was used to provide insight into the trade-off between time losses and heat losses. A maximum brake thermal efficiency of 37.2% was achieved.

Abstract:
The objective of the proposed research is to develop structural changes to the design and application of electromagnetic (EM) sensing models to more efficiently and accurately invert EM measurements to extract parameters for applications such as landmine detection. Two different acquisition modalities are addressed in this research: ground-penetrating radar (GPR) and electromagnetic induction (EMI) sensors. The models needed for practical three-dimensional (3D) spatial imaging typically become impractically large, with up to seven dimensions of parameters that need to be extracted. These parameters include, but are not limited to target type, 3D location, and 3D orientation. The new special structures for these models exploit properties such as shift invariance and tensor representation, which can be combined with strategic inversion techniques, including the Fast Fourier Transform and semidefinite programming. The structures dramatically reduce the amount of computation and can eliminate the need to store up to five dimensions of parameters while still accurately estimating them.

Abstract:
Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2011.
Cataloged from PDF version of thesis.
Includes bibliographical references (p. 193-200).
Parabolic trough collectors are a low cost implementation of concentrated solar power technology that focuses incident sunlight onto a tube filled with a heat transfer fluid. The efficiency and cost of the parabolic trough collector designs is influenced by structural stiffness, choice of materials, assembly tolerances, mirror cleanliness and wear. Current performance estimates of solar trough optical field efficiencies are 54.2% [1]. The goal of this research is to identify general methods and specific design concepts for achieving increased collector efficiency. This thesis has investigated improvements in the design of a parabolic trough module by looking first at the overall structural concept of the collector to reduce complexity while maintaining structural stability under wind loading conditions. In the process of evaluating the feasibility of one such concept, a monolithic reflector panel with a mirror film front surface, details related to the mirror surface efficiency were investigated. At the panel-structure to mirror interface, surface roughness of the underlying structural backing was studied to understand performance effects on the mirror film surface that would make one backing material potentially more suitable than another would. In this case it was found that three materials tested: gel-coated fiberglass, rolled aluminum, and rolled steel were all similarly effective when compared to a more expensive mirrored aluminum backing material. When looking at the integration of the larger structural changes with the factors that affect surface reflectivity of parabolic mirrors, it became apparent that contamination of the surfaces and cleaning were major factors in reduced module effectiveness. Given that the conceptual development of the structure is ongoing, research into contamination factors and potential cleaning solutions were considered in such a way that panel cleaning solutions could be integrated into the trough module design from the start. A vortex generator cleaning concept, which uses V-shaped extruded forms to create vortices over a mirror panel in the presence of flow over the surface, was tested as a passive cleaning solution.

Abstract:
This thesis investigated the design decisions and associated optimisation methods of a 1.3 GHz Multiple Beam Klystron (MBK) for use in the Compact Linear Collider (CLIC). In this regard refinements have been made both to the MBK design, and investigation and optimisation methods used. The high desired efficiency of 80% requires low perveance beams, to achieve the specification output power 20 beams are needed. The choice of cavity used in the interaction structure of a klystron has a large impact on its size and efficiency. To optimise this a number of possible cavity designs were produced and compared to confirm selection of the most appropriate. The fundamental mode (TM0, 1, 0) coaxial cavity was selected due to its superior R/Q of 130-210 W and suitability as a 2nd harmonic cavity. Although the dipole mode proved to be close in frequency to the operating mode (within ~ 50 MHz), raising concerns of stability issues in an MBK. A novel model was developed using standard wake field theory to investigate the effects of this mode the klystron’s stability. A strategy for shifting this mode using a coupled shifting gap was proposed and achieves a shift of 125 MHz, although the models findings suggest it is not a significant problem. Existing methods of calculating dipole and higher order modes proved time consuming thus impeded a fully investigation of stability issues. An extended method of moments model allows efficient calculation of monopole and higher order modes. The model’s basis functions are altered to represent a range of TM and TE modes with azimuthal variation, allowing their rapid and accurate calculation. Optimising the klystron interaction structure by hand to find a viable configuration revealed shortcomings in this standard approach, although the target efficiency was achieved. An algorithmic approach was deemed necessary to allow a full investigation within reasonable time limits. The field of evolutionary algorithms is presented and an evolutionary algorithm to automate the optimisation of klystron interaction structures was developed. A number of important related issues were dealt with and suitable interaction structures (optimised for efficiency, bandwidth, length and electron exit velocity) produced. Finally a design was proposed for both the input and output couplers which is inspired by a coupler used in a gyrotron. Unconventionally, the latter exits the tube axially avoiding the focusing solenoid, but excessive heating may preclude its use.

Abstract:
Eco-efficiency improvements in manufacturing is a controversial subject for researchers, practitioners as well as policy makers. The widely accepted definition of "doing more with less" is not accurate enough to guide the design of improvements that can deliver products in a sustainable way. The outcome of these challenges is evident through significant environmental performance variations across various levels of manufacturing operations. The study is driven by the complexity of manufacturing systems and sought to offer design support for practitioners that aim to improve eco-efficiency. A maturity model has been developed in this work that simulates the influence of manufacturing practices on eco-efficiency. The model takes the form of a maturity grid (PMGE) that overlooks practices at process, management systems and top-management levels and incorporates 15 dimensions of performance overall. Evidence shows that practices tend to evolve from reactive to proactive as manufacturing systems mature and embrace eco- efficiency as a systemic property. It was also found that mature companies achieve improvements in energy and resources by relying on existing internal capabilities. Tools to facilitate research and intervene with practitioners in real-life problems were developed and tested. The researcher combined research findings and tools into a maturity-based method (PMGEM) for eco-efficiency improvements. The method intends to help practitioners plan and design eco- efficiency improvements aligned to existing internal capabilities and adopt a more proactive behaviour to environmental challenges. PMGEM was ultimately applied in two case studies with ultimate goal to help practitioners resolve real-life challenges. The applications were positively commented and encourage further work in this field. The researcher envisages that methods such as PMGEM are deeply needed in manufacturing to support practitioners approach complex concepts such as eco-efficiency. Simplification and decomposition techniques with a clear intended use can facilitate the implementation of ambitious improvement strategies for sustainable development.

Abstract:
Abstract The algebra of rotations is an alternative method for describing rigid body rotations. It can be efficiently used in the kinematic analysis of robots. One of the basic problems of the algebra of rotations is to determine the resultant sum of a number of sequential joint rotations. For this calculation, four new methods, in addition to the two methods already available in the literature, are proposed in this paper. The six methods are then compared analytically and numerically on the basis of the computational efficiency. The limitations to each of the methods are also discussed. It is found that the equivalent Rodrigues parameter method is the most efficient. However, the equivalent Euler parameter method is the preferred method for use since it is infinity free, initial vector independent and reasonably efficient.

Abstract:
In what ways and to what extent are bioinspired designs (BIDs) and the biological systems that inspire them ‘efficient’? The answer to this question provides insight into the potential role BID could have in the generation of energy- and materials-efficient designs. By qualifying and clarifying efficiency-related claims in the context of biological evidence, this paper contributes to the theoretical foundation for BID for efficiency and provides guidance to those developing design tools and methodologies aimed at using BID to enhance the efficiency of engineered products and systems. This paper is organized into three main sections. First, a study is presented examining the reasons authors in the BID community cite when motivating their work. Of the 127 sources analyzed, 40 referenced ‘efficiency’, establishing empirically that efficiency of BIDs and the biological organisms that inspire them is a central motivation for work in BID. Second, efficiency-related claims most commonly made by authors in BID are explained and analyzed using authoritative biological and BID literature. Ultimately, some of the claims prove problematic. However, when qualified appropriately, these claims provide significant insight into how the oft-cited examples of efficiency in biology and BID have arisen. Finally, a study uncovering trends in sustainable BIDs is presented, and the efficiency-related trends are discussed. This study provides examples of some efficiency-related characteristics of biological systems that are successfully being transferred to engineered products and systems through BID. Specifically, the sustainable BIDs analyzed are shown to frequently meet four efficiency-related green design guidelines (GDGs) better than functionally-equivalent non-bioinspired alternatives. Additionally, passive mechanisms, multifunctional designs, and optimized geometries are discussed and shown to be prevalent in the sample of sustainable BIDs studied.
