A 3D finite element model was developed for the simulation of drilling burr formation processes of 304L stainless steel. The nonlinear thermo-elastic-plastic model simultaneously accounts for dynamic effects of mass and inertia, strain hardening, strain rate, automatic mesh contact with friction capability, material ductile failure and temperature-mechanical coupling. Material ductile failure criteria were proposed to simulate drilling burr formation. Based on a series of stress contours and the progressive deformation of the workpiece edge obtained from simulation, a drilling burr formation mechanism was proposed and divided into four stages: initiation, development, pivoting point, and formation stages with cap formation. The burr thickness is largely determined by the distance between the pre-defined machined surface and the pivoting point, while the burr height is determined by the positions of the pivoting point and the cap formation. The FEM simulation demonstrates the dominant roles of negative shearing and bending mechanisms in the drilling burr formation process. The simulation results coincide with phenomenological observations of burr geometry from drilling 304 stainless steel and plasticine work materials. [S1087-1357(00)01202-8]

AbstractThe problem of solving large-scale systems of linear algebraic equations arises in a wide range of applications. In many cases the preconditioned iterative method is a method of choice. This paper deals with the approximate inverse preconditioning AINV/SAINV based on the incomplete generalized Gram–Schmidt process. This type of the approximate inverse preconditioning has been repeatedly used for matrix diagonalization in computation of electronic structures but approximating inverses is of an interest in parallel computations in general. Our approach uses adaptive dropping of the matrix entries with the control based on the computed intermediate quantities. Strategy has been introduced as a way to solve di cult application problems and it is motivated by recent theoretical results on the loss of orthogonality in the generalized Gram– Schmidt process. Nevertheless, there are more aspects of the approach that need to be better understood. The diagonal pivoting based on a rough estimation of condition numbers of leading principal submatrices can sometimes provide inefficient preconditioners. This short study proposes another type of pivoting, namely the pivoting that exploits incremental condition estimation based on monitoring both direct and inverse factors of the approximate factorization. Such pivoting remains rather cheap and it can provide in many cases more reliable preconditioner. Numerical examples from real-world problems, small enough to enable a full analysis, are used to illustrate the potential gains of the new approach.

Robotic manipulation of a bulky object is challenging due to the limited kinematics and payload of the manipulator. In this study, a robot realizes the manipulation of general-shaped bulky objects utilizing the contact with the environment. We propose a hierarchical manipulation planner that effectively combined three manipulation styles, namely, pivoting, tumbling, and regrasping. In our proposed method, we first generate a set of superimposed planar segments on the object surface to obtain an object pose in stable contact with the table, and a set of points on the object surface for the end-effectors (EEFs) of a dual-arm manipulator to stably grasp the object. Object manipulation can be realized by solving a graph, considering the kinematic constraints of pivoting and tumbling. For pivoting, we consider two supporting styles: stable support (SP) and unstable support (USP). Our proposed method manipulates large and heavy objects by selectively using the two different support styles of pivoting and tumbling according to the conditions on the table area. In addition, it can effectively avoid the limitation arising due to the arm kinematics by regrasping the object. We experimentally demonstrate that a dual-arm manipulator can move an object from the initial to goal position within a limited area on the table, avoiding obstacles placed on the table.

Low-rank matrices arise in many scientific and engineering computations. Both computational and storage costs of manipulating such matrices may be reduced by taking advantages of their low-rank properties. To compute a low-rank approximation of a dense matrix, in this paper, we study the performance of QR factorization with column pivoting or with restricted pivoting on multicore CPUs with a GPU. We first propose several techniques to reduce the postprocessing time, which is required for restricted pivoting, on a modern CPU. We then examine the potential of using a GPU to accelerate the factorization process with both column and restricted pivoting. Our performance results on two eight-core Intel Sandy Bridge CPUs with one NVIDIA Kepler GPU demonstrate that using the GPU, the factorization time can be reduced by a factor of more than two. In addition, to study the performance of our implementations in practice, we integrate them into a recently developed software StruMF which algebraically exploits such low-rank structures for solving a general sparse linear system of equations. Our performance results for solving Poisson's equations demonstrate that the proposed techniques can significantly reduce the preconditioner construction time of StruMF on the CPUs, and the construction time can be further reduced by 10%–50% using the GPU.

This article focuses on the engineering of pivoting sunshade structures for the Dubai Expo 2020, which won a Structural Award 2022. Synopsis Most engineers will be familiar with regular-shaped, fixed buildings or structures and how to design to ensure loads can safely be transferred to the ground. But what happens when your structure is bespoke, irregular, permeable, flexible and moveable? This article outlines the unique challenges involved in developing a successful design for the shade structures at the Dubai Expo, which involved extensive wind tunnel testing, prototyping and engineering well outside the Eurocodes and usual day-to-day work of most structural engineers. The project won a Structural Award 2022 under the Process attribute that recognises technical achievement and innovation.

Short-term wind forecasting is critical for the dispatch, controllability and stability of a power grid. As a challenging but indispensable work, short-term wind forecasting has attracted considerable attention from researchers. In this paper, Principal Component Analysis (PCA) is applied to Computational Fluid Dynamics (CFD) calculation results for feature extraction and then combined with sparse sensing to achieve the rapid reconstruction of a three-dimensional wind speed field and pressure field. Before reconstruction, the relationship between the reconstruction error and the noise level, and a number of the basis vectors is systematically studied. In the simulation, the wind shear effect is introduced into the inlet boundary condition, and the reconstruction errors of the uniform inlet are 0.21% and 6.46%, respectively, while the maximum reconstruction errors including the wind shear effect are 1.21% and 6.41%, respectively, which verifies the feasibility of applying a PCA-based reconstruction algorithm to a 3D wind field reconstruction. In addition, to solve the time-consuming problem of most optimization algorithms based on a brute-force combinatorial search, an innovative optimization algorithm based on the QR pivoting is investigated to determine the sparse sensor placements. Simulation results show that when the number of sensors is equal to the number of basis vectors, the error of random placement is even 20 times of the optimal placement, which illustrates that QR pivoting is a powerful optimization algorithm. Finally, a wind tunnel experiment of velocity field reconstruction is performed, to verify the practicability of the optimized method based on QR pivoting, and the results indicate that a reasonably high accuracy 3D wind field can be obtained with only 10 sensors (the error of most points is less than 5% and the minimum error is only 0.74%). In general, the proposed algorithm incorporating PCA, sparse sensing and QR pivoting can quickly reconstruct the 3D velocity and pressure fields with reduced measurement costs, which is of great significance for the development of short-term wind forecasting methods.

In the Spring of 2020, closures and safe distancing orders swept much of the United States due to the COVID-19 pandemic. This paper presents a case study of pivoting an in-person empowerment program focused on lifestyle interventions for people newly diagnosed with Mild Cognitive Impairment (MCI) to an online program. Working as rapidly as possible to sustain participant engagement, our design decisions and subsequent iterations point to initial constraints in telehealth capabilities, as well as learning on the fly as new capabilities and requirements emerged. We present the discovery of emergent practices by family members and healthcare providers to meet the new requirements for successful online engagement. For some participants, the online program led to greater opportunities for empowerment while others were hampered by the lack of in-person program support. Providers experienced a sharp learning curve and likewise missed the benefits of in-person interaction, but also discovered new benefits of online collaboration. This work lends insights and potential new avenues for understanding how lifestyle interventions can empower people with MCI and the role of technology in that process.

In this article, we address the vital, yet largely ignored role conversations among researchers play in furthering qualitative research projects. We identify conversations as vital when they foster creativity and afford the researchers an opportunity for clearer focus. Through a close examination of four distinctly different qualitative research experiences, we show how these conversations open and deepen reflective relationships among the researchers and with the phenomenon being studied, both of which lead to a reformulation of the research process. Finally, we suggest that these kinds of conversations emerge out of relational contexts that honor personal meaning, care, openness, and even vulnerability among researchers.

This paper presents our concepts and initial investigation of a novel construction automation approach using a new layered fabrication process called Contour Crafting (CC). The process aims at automated construction of whole houses as well as sub-components. The potential of CC became evident from the initial investigations and experiments with various materials and geometries. Using this process, a single house or a colony of houses, each with possibly a different design, may be automatically constructed in a single run. CC uses computer control to take advantage of the superior surface forming capability of trowels to create large intricate structures with smooth and accurate surfaces.

Sales are a subject that most people consider to be an art. The truth is that there are several sophisticated methodologies on how to successfully close a deal. However, time goes by, customers get smarter and the markets shifts. As a result sales methods start to fade away and do not necessarily work the way they used to. This thesis was conducted in co-operation with SimCorp A/S and aims to examine the concept of Insight Selling. The concept was developed by analysing top performers and how they manage to sell in an economic downturn. The purpose is to investigate how an organisation can apply the core principles of the new sales strategy on an existing sales process and current customer relationship management system. A qualitative research method was used and interviews were conducted to gather data to gain a deeper understanding on the topic of sales. The result exhibits a situation analysis that was conducted to create a representation of SimCorp’s current sales process. With the key elements of insight selling a proposed model of a future state was presented. Lastly, a requirements analysis of the customer relationship management system currently deployed at the company was designed based on the findings. The result indicated that it was possible to apply the key elements of insight selling on the current sales process. The method might be suitable for some situations but it does not replace or eliminate earlier practices.Det är vanligt att uppfatta försäljning som en konst. Sanningen är att det finns väl beprövade metodiker för hur man ska lyckas för att sälja. Med tiden har konsumenter blivit smartare och marknaden förändrats. Detta har resulterat i att många säljmetoder blir avlägsna och inte lika användbara och pålitliga som de var innan. Examensarbetet utfördes i samarbete med SimCorp A/S där syftet är att undersöka begreppet insiktsförsäljning. Konceptet utvecklades från en studie där man analyserade de högpresterande säljarna och identifierade hur de lyckades sälja under en ekonomisk lågkonjunktur. Syftet är att undersöka hur en organisation kan applicera de nya strategierna som presenteras inom insiktsförsäljning på en befintlig försäljningsprocess och det nuvarande kundhanteringssystemet. En kvalitativ forskningsmetod applicerades och intervjuer utfördes för att ackumulera data och få en djupare förståelse av ämnet försäljning. I resultatet presenteras en nulägesanalys av SimCorp’s nuvarande försäljnings-process. Vidare presenteras ett förslag på hur en försäljningsprocess med inslag av strategierna från insiktsförsäljning kan se ut. Slutligen utfördes en kravanalys på insiktsförsäljnings metod för att implementeras och testas på det nuvarande kundhanteringssystemet. Resultatet indikerade att det var möjligt att applicera nyckel elementen från insiktsförsäljning på den nuvarande säljprocessen. Metoden är lämplig för att användas i vissa situationer men ersätter inte eller eliminerar tidigare rutiner.

Le concept de pivot reçoit beaucoup d'attention sur internet, dans le milieu de l'enseignement, par les accélérateurs de start-up et chercheurs en ingénierie. Toutefois, ce concept reste encore peu exploré dans le domaine scientifique et plus particulièrement en sciences de gestion. De plus, la littérature traitant du sujet n'aborde pas explicitement le processus de pivot de manière systémique en considérant l'entrepreneur, ses artefacts et les acteurs de son écosystème comme un tout indissociable. Par conséquent, l'objectif de ce travail de recherche est de comprendre le processus de pivot dans sa complexité en considérant cette triade comme étant le plus petit élément d'étude. Cette thèse, reposant sur un paradigme épistémologique constructiviste, considère l'entreprise comme un système complexe dont l'intelligibilité doit être trouvée non seulement dans le système lui-même, mais également dans les relations que ce système entretient avec son environnement.La résolution de cette problématique de recherche autour de la notion de pivot s'est déroulée en deux étapes. Dans un premier temps, une revue de la littérature est effectuée et trois propositions de recherche ainsi qu'une modélisation systémique du processus de pivot sont construites par rapport à celle-ci. Dans un deuxième temps, ces propositions et cette modélisation sont confrontées au terrain par le biais d'une étude de cas afin d'évaluer leur robustesse. À la suite de cela, la modélisation systémique du processus de pivot construite par rapport à la littérature est ajustée en conséquence. L'originalité de cette thèse réside dans la grille de lecture systémique mobilisée pour aborder la complexité du processus de pivot. Cette grille de lecture est la triade entrepreneur, artefacts et acteurs de l'écosystème, ainsi que les interactions entre les éléments de cette triade.Cette thèse apporte quatre contributions. Premièrement, elle met en avant une vision holistique du processus de pivot basé sur la systémique. Deuxièmement, elle propose un point de départ pour de futures recherches autour de la notion de pivot. Ce point de départ repose sur une modélisation systémique du processus de pivot validée par une étude de cas. Troisièmement, elle suggère aux entrepreneurs de conserver de la variété au niveau de leur organisation afin d'être plus à même de s'adapter aux changements survenant dans leur environnement. Cette variété se rapporte non seulement au nombre d'éléments présents dans l'organisation, mais également au nombre d'interactions que ces éléments entretiennent les uns avec les autres. Quatrièmement, elle offre une nouvelle définition du concept de pivot basée sur la systémiqueThe term pivoting is widely used on the internet, in the educational community, by start-up accelerators and engineering researchers. However, pivoting is still little explored in the scientific field, particularly in management sciences. Moreover, the literature on the subject does not explicitly address the process of pivoting by considering the entrepreneur, his artifacts, and the actors of his ecosystem as an inseparable whole. Therefore, this thesis aims to understand the process of pivoting by considering this triad as the smallest element of study. This thesis, based on a constructivist epistemological paradigm, considers the company as a complex system whose intelligibility must be found not only in the system itself but also in the relations that the system has with its environment.The resolution of this research problem was carried out in two stages. In the first stage, based on the literature on pivoting, three research propositions and a systemic model of the process of pivoting are developed. In the second stage, these research propositions and this model are tested empirically utilizing a case study. Following this, the systemic model of the process of pivoting developed from the literature is adjusted accordingly. The originality of this thesis lies in the systemic reading grid used to address the complexity of the pivot process. This reading grid is the triad of entrepreneurs, artifacts, and ecosystem actors, as well as the interactions between the elements of this triad.This thesis makes four contributions. First, it puts forward a holistic view of the process of pivoting based on system theory. Secondly, it provides a starting point for future research on pivoting. This starting point is based on systemic modeling of the process of pivoting validated by a case study. Thirdly, it suggests that entrepreneurs should maintain variety in their organization to better adapt to environmental changes. This variety refers not only to the number of elements present in the organization but also to the number of interactions these elements have. Fourthly, it offers a new definition of pivoting based on system theory

George Balanchine’s arrival in the United States in 1933, it is widely thought, changed the course of ballet history by creating a bold and original neoclassical style that is celebrated as the first successful “American” manifestation of the art form. Making Ballet American: Modernism Before and Beyond Balanchine intervenes in the prevailing historical narrative and rebalances Balanchine’s role in dance history by revealing the social, cultural, and political forces that actually shaped the Americanization of neoclassical ballet. Situating American ballet within a larger context of literary, musical, art, and dance modernism, Harris examines a series of critical efforts, most prominently by Lincoln Kirstein and Edwin Denby, to craft new, modernist ideas about the relevance of classical dancing for American society. The book’s unique structure interweaves chapters focused on cultural and intellectual histories of ballet criticism and production with close examinations of three American ballets in the Depression, World War II, and Cold War eras: Eugene Loring’s Billy the Kid (1938), Agnes de Mille’s Rodeo (1942), and Balanchine’s Western Symphony (1954). Through this blend of cultural and choreographic analysis, Making Ballet American illustrates the evolution of modernist ballet theory and practice during a turbulent historical period. Ultimately, Making Ballet American argues that the Americanization of Balanchine’s neoclassicism was not the inevitable outcome of his immigration or his creative genius, but rather a far more complicated process that spanned several authors and continents, always pivoting on the question of modern ballet’s relationship to America and the larger world.

This chapter traces how entrants from legacy industries in Germany used public resources originally intended to support technological innovation in traditional sectors such as machine tools and automobile supplies. It explains why, even in new sectors such as wind and solar, German firms reproduced historical patterns of flexible specialization, customization, and small-batch production. The chapter begins with a discussion of industrial origins of Germany’s wind and solar firms, focusing in particular on machine tools, automation, and automotive sectors. It then outlines the learning process that firms navigated in pivoting from their existing industries into new industrial sectors. The second half of the chapter focuses on the two key resources that enabled these developments: collaboration with China and domestic institutional legacies.

Анотація:
The spreading of collaborative practices in the production and consumption of goods and services constitutes an unavoidable challenge to researchers aiming at understanding the sociospatial dynamics of economic life. Fablabs in particular are identified as expressions of a new form of material production pivoting on collaboration and democratised innovation. Embracing a recent claim in economic geography for an appreciation of the relevant role of spatial dynamics in organizations (Müller 2015), I argue for an investigation of collaborative workplaces through an ethnographic research of the situated practices involved in the process of organising a Fablab. Drawing on Actor-Network Theory and the ‘performativity programme’ launched by Michel Callon (1998), the chapter argues that collaborative economies could be analysed as the emergent outcome of the interaction between economic theories and heterogeneous socio-technical arrangements through which they are brought into being, showing how economics performs the economy. In order to unpack the contingent, situated, and fragile nature of this process with regards to Fablabs and Makers, the chapter discusses the data from an ethnographic investigation of a Fablab in Turin, Italy, working on two levels. Firstly, it identifies the economic theories involved in the process of performing Fablabs as collaborative and open spaces within contemporary urban economies. Secondly, it shows how sociospatial processes of organizing participate in the enactment of an economy where production and innovation have been ‘democratised’ and where collaboration and sharing are at the core of value production. However, the chapter highlights also how the process of actualization is never stable, resulting sometimes in failures and ‘misfires’ (Callon 2010).

“A man lives not only his personal life, as an individual, but also, consciously or unconsciously, the life of his epoch and his contemporaries.” Thomas Mann’s 1924 words on war, memory, and art also distils his emblematic encounter with Matthias Grünewald’s Isenheim Altarpiece.1 Transported from Colmar to Munich in October 1917, exhibited from 1918–19 at the Munich Alte Pinakothek, as this article explores, it became the focus of an extraordinary moment of German national crisis and expiation widely imaged, projected, reported, and seen by countless visitors including Mann. My concerns are two-fold. First, to explore responses in word and image stimulated by the Altarpiece’s display and extensive photographic imaging in the contexts of a significant cultural shift toward engagement with the potency of medieval art, and its mediation of practices of “uncanny” memory. Entwined with an acute sense of present trauma, this activates what Hans Belting calls the borderlines between memory and image; devotion and distance2—pivoting in 1918–19 on the Altarpiece’s power as an afterlife, restaged to make present what appears absent: a medieval turbulence as a contemporary imaging and consciousness of pain. Second is to consider how this process becomes amplified in the aftermath of the war, in particular, via its writing as an unheimlich past in Thomas Mann’s The Magic Mountain, echoed in Marc Bloch’s invocation of a material memory of power, malady and sacred touch in his Les Rois thaumaturges, both 1924. Thus the conclusions suggest the recurrent, yet overlooked artistic figure of pre-modern memory within this constellation as pivotal to an imaginary of the unimaginable of what is seen and unseen.

The COVID-19 pandemic led educators to quickly pivot to continue teaching. Negative effects include exacerbated academic achievement gaps between SES groups, less access to health services, aggravated digital divides, widened academic achievement gaps, and enormously interrupted the education processes. Positive changes include educator optimism for digital portfolios, simulated lesson planning, and delivery; supports for social-emotional engagement; seamless transitions to remote learning; and seeing recalcitrant individuals revise and adapt teaching formats, relationship-building, increased quality online education, and motivation to try innovations. Relational humanity is an integral part of the faculty-student relationship; showing students they matter as humans and deepening relationships with them is a humanitarian act. The pivot forced variations, created disequilibrium, celebrated innovations, and yielded creative delivery models. Faculty are now re-examining their content and delivery in the spirit of creating an improved student experience for all modalities of instruction.

Higher education today is faced with many challenges. However, behind some of those challenges are potential opportunities. One in particular is the focus on diversity, equity, and inclusion, and especially the unpacking of systems and processes that are increasingly becoming more prevalent in higher education's ecosystem of support, mainly for Indigenous students. This is due in large part to the global shift in the rising diverse student populations across college and university campuses. Indigenous students are entering today's evolving college landscape with a clear sense of purpose. To take advantage of this opportunity, institutions are pivoting their support structures to also facilitate their diverse student populations and learning outcomes. They are developing programs to make sense of the Indigenous student experiences, issues, challenges, and are paying special attention to strategies and infrastructures designed to safeguard their student success.

Abstract This chapter explores the place of party politics in the growth model research agenda. Since dominant growth coalitions are unlikely to represent a majority of the electorate, we posit that parties play a key role in the construction and maintenance of the political alliances that underpin growth regimes. Drawing on the cases of Germany and the United Kingdom, we argue that electoral politics should not be seen as epiphenomenal to growth models, but neither do they shape institutional development in the direct way imagined by optimistic accounts of how parties “matter.” Examining how parties and leaders manage processes of growth model reform allows us to move beyond the dichotomy of organized interests versus electoral dominance that has hitherto conditioned the debate on growth models. Pivoting to the recent rise in anti-system politics, we show that growth models cannot insulate themselves from electoral pressures, particularly when they fail to deliver growth.

Abstract Cross sectioning has proven over the years to be a failure analyst's most important tool for examining the depth-related features of a sample. This paper discusses a.sample block design that allows angled as well as normal (90 degree) sectioning without remounting the sample. This in turn allows for much faster cross sections, with time savings not only from avoiding remounting the sample, but also in the polishing process itself, particularly with silicon-on-sapphire dice.

A new methodology for modeling and updating the in-process workpiece geometry in milling is presented in this paper. The methodology is developed for general milling processes, in which the cutter can be any shape and follow any tool path trajectory even with self-intersections. And the in-process workpiece is updated with retained sharp features. The associated procedure starts by modeling both the cutter and the workpiece as closed manifold triangle meshes. The mesh model of the cutter swept volume is then generated from repeatedly sampled mesh vertices of the cutter along its trajectory using the ball-pivoting algorithm. The workpiece is updated by a subtraction Boolean operation between the workpiece and the cutter swept volume. An octree space partitioning algorithm is adopted in order to efficiently obtain the exact triangle-to-triangle intersection points. As the last step, a filling operation is performed around the intersection points to establish the closed manifold updated workpiece geometry. Several case studies have been performed to demonstrate the effectiveness of the proposed methodology.

The design optimization of an actuation mechanism for a dual-arm scara-type robotic manipulator is presented. The manipulator is to be used in a vacuum environment for wafer handling applications in the semi-conductor manufacturing industry. The actuation mechanism consists of a pivoting platform that serves as the common driver link for two four-bar mechanisms each of which drives a scara-type arm. Each of the scara-type arms has a substrate carrying end-effector to pick from or place substrates on a process module. When the pivoting platform is in its neutral position, both of the arms are retracted. When the platform swings to one side, the arm on that side extends while the arm on the other side remains close to retracted position. The actuation mechanism is unique in that it uses just one motor to control the extension of both arms in contrast to the conventional design where each arm requires a motor of its own. However, the design needs to be optimized in order to minimize the effects of kinematic coupling between the two arms and, at the same time, keep the motor torque requirements and encoder resolution requirements to within practical limits. In this article, the relationships between the link lengths of the actuation mechanism, the kinematic coupling between the two arms, maximum encoder resolution requirements and motor torque requirements are described. These relationships are presented in the context of motion profiles characterized by limits on substrate acceleration — a typical requirement in wafer handling applications in vacuum. A methodology for determining link lengths to minimize motor torques and kinematic coupling between arms is presented.

Abstract Manufacture and use of metal bands, sheets, and cables often requires high-speed axial transport of the material. Disturbance forces can cause vibration to propagate through the process due to the bending stiffness coupling between adjacent roller-supported spans. This paper introduces an active pivoting roller that adaptively decouples adjacent spans, thereby isolating a controlled span from bounded disturbances in an adjacent span. The system includes a partial differential equation for the two spans and an ordinary differential equation for the actuator. Exact model knowledge and adaptive isolation controllers, based on Lyapunov theory, regulate the controlled span from bounded disturbances in the adjacent, uncontrolled span. Assuming distributed damping in the uncontrolled span, the exact model knowledge and adaptive controllers exponentially and asymptotically drive the controlled span displacement to zero, respectively, while ensuring bounded uncontrolled span displacement and control force.

Abstract Owner operators are tasked with the challenge of maximizing energy efficiency and overall energy management for highly complex and integrated operations, to which the downside has cost industry millions of dollars yearly. To realize optimum value of energy management and optimization, delegates will see how real time optimization is crucial with respect to advanced process control for complex operational conditions - not just integration, but what" to do" and "not to do". Using an integrated approach of real-time optimization and advanced process control, delegates are shown the value of advanced process control, and under what scenarios real time optimization supports, compliments, and drives the overall energy optimization opportunities operationally. Demonstrated through successful industry use cases, the focus will be on identifying the right architecture and the right decision-making processes required for optimum energy optimization, including core considerations and limitations faced by the industry. Further, this paper will explore and articulate operational challenges faced during design, implementation, and scaling - providing delegates the insight to both the risk and reward. This paper will detail the result of successfully integrated real time optimization and advanced process control architectures, providing different levels of return to operational requirements and complexity. Using core industry use cases, delegates will be able to see both the successes and lessons learned of the applied architectures reflecting different operational conditions. In conjunction, this paper will re-emphasize the design and deployment requirements for success, pivoting around the limitations of advanced process controls within certain operations. To this effect, this paper will highlight the main return on investment opportunities to delegates, focusing on maximizing profits and production whilst minimizing overall utility costs. With complex integrated operations, delegates will get an insight into these tangible potentials and how they can benefit from different architectures which address different operational requirements from an energy management and efficiency domain.

Two vital skills for an engineering graduate are the abilities to reason and communicate effectively. Laboratory work is one of the principle ways in which students exercise these competencies. In a typical undergraduate engineering course (particularly those at the freshman or sophomore level), laboratory exercises are often designed for students (rather than by them). They must simply follow procedures to find pre-determined results in order to “drive home” theoretical concepts. As a result, students are left with a poor concept of the purpose and power of experimentation, and consequently the laboratory experience detracts from rather than bolstering their critical thinking skills. A one factor at a time approach is often the default method for undergraduate engineering experiments, and while it is relevant for acquiring initial skills at the freshmen and sophomore levels, the approach may only promote lower level thinking skills. Even so, these experiences are pivoting in establishing sound engineering practices among students. In addition, statistical design of experiments could be explored for implementation for junior and senior level design courses. This project sought to provide an example of higher order thinking by performing a statistically-designed beam deflection experiment. The experimental objectives were to determine if load, span, geometry, and material affected the deflection of simply supported beams and to identify significant nuisance factors. Key nuisance effects included support stiffness, the reaction measurement procedure, and the effect of built-up members. In conclusion, the paper points out how undergraduate students could benefit from exposure and participation in such a design of experiments process even though students were not involved in this study originally.
