    PAIR distinguished lecture series : digital twinning the built environment

    PAIR distinguished lecture series : digital twinning the built environment

    The lecture commenced with a welcome speech by Prof. CHEN Qingyan, Director of PAIR, followed by a brief speaker introduction by Prof. Christopher CHAO, Vice President (Research and Innovation).
    In his presentation, Prof. Brilakis first gave a brief introduction to digital twins (DT), pointing out that DT plays a central role in digital transformation. Next, he elaborated on the application of DT in the construction industry and explained how DT is involved in the planning, design, construction, maintenance and operation processes. He introduced research conducted at the University of Cambridge on inexpensive methods for generating object-oriented infrastructure geometry, detecting, and mapping visible defects on the resulting DT, automatically extracting defect spatial measurements, and sensor and sensor data modelling. Prof. Brilakis also provided examples of how these resulting DT are further exploited in design for manufacturing and assembly (DfMA), mixed-reality-enabled mobile inspection, and proactive asset protection from accidental damage. To conclude, Prof. Brilakis stated that DT, smart materials, data science, and automation & bobotics, constitute important digital assets for driving sustainability, and pointed out the future development directions in these areas.
    A question-and-answer session moderated by Prof. DING Xiaoli, Director of the Research Institute for Land and Space (RILS), and Prof. WANG Yuhong, Member of RILS, followed. This session provided both the online and on-site audience with an opportunity to engage in a fruitful discussion with Prof. Brilakis.

    Introduction to Aerospace Structures and Materials

    Introduction to Aerospace Structures and Materials

    This book provides an introduction to the discipline of aerospace structures and materials. It is the first book to date that includes all relevant aspects of this discipline within a single monologue. These aspects range from materials, manufacturing and processing techniques, to structures, design principles and structural performance, including aspects like durability and safety. With the purpose of introducing students into the basics of the entire discipline, the book presents the subjects broadly and loosely connected, adopting either a formal description or an informal walk around type of presentation. A key lessons conveyed within this book is the interplay between the exact science and engineering topics, like solid material physics and structural analysis, and the soft topics that are not easily captured by equations and formulas. Safety, manufacturability, availability and costing are some of these topics that are presented in this book to explain decisions and design solutions within this discipline.

    Forensic Engineering: Learning from Failures

    Forensic Engineering: Learning from Failures

    What do collapsed buildings, infected hospital patients, and crashed airplanes have in common? If you know the causes of these events and conditions, they can all be prevented. In this course, you will learn how to use the TU Delft mind-set to investigate the causes of such events so you can prevent them in the future. When, for instance, hundreds of hospital patients worldwide got infected after having gall bladder treatments, forensic engineering helped reveal how the design and use of the medical instruments could cause such widespread infections. As a result, changes were made to the instrument design and the procedural protocols in hospitals. Learning from failure in this case benefitted patient health and safety across the world. After taking this course you will have an understanding of failures and the investigation processes used to find their causes. You will learn how to apply lessons gained from investigating previous failures into new designs and procedures.

    Computation Structures

    Computation Structures

    This course introduces architecture of digital systems, emphasizing structural principles common to a wide range of technologies. It covers the topics including multilevel implementation strategies, definition of new primitives (e.g., gates, instructions, procedures, processes) and their mechanization using lower-level elements. It also includes analysis of potential concurrency, precedence constraints and performance measures, pipelined and multidimensional systems, instruction set design issues and architectural support for contemporary software structures.

    Elements of Mechanical Design

    Elements of Mechanical Design

    This is an advanced course on modeling, design, integration and best practices for use of machine elements such as bearings, springs, gears, cams and mechanisms. Modeling and analysis of these elements is based upon extensive application of physics, mathematics and core mechanical engineering principles (solid mechanics, fluid mechanics, manufacturing, estimation, computer simulation, etc.).

    Using Six Sigma DMAIC Methodology and Discrete Event Simulation to Reduce Patient Discharge Time in King Hussein Cancer Center

    Using Six Sigma DMAIC Methodology and Discrete Event Simulation to Reduce Patient Discharge Time in King Hussein Cancer Center

    Short discharge time from hospitals increases both bed availability and patients and families satisfaction. In this study, the Six Sigma process improvement methodology was applied to reduce patients discharge time in a cancer treatment hospital. Data on the duration of all activities, from the physician signing the discharge form to the patient leaving the treatment room, were collected through patient shadowing. These data were analyzed using detailed process maps and cause-and-effect diagrams. Fragmented and unstandardized processes and procedures and a lack of communication among the stakeholders were among the leading causes of long discharge times. Categorizing patients by their needs enabled better design of the discharge processes. Discrete event simulation was utilized as a decision support tool to test the effect of the improvements under different scenarios. Simplified and standardized processes, improved communications, and system-wide management are among the proposed improvements, which reduced patient discharge time by 54 from 216 minutes. Cultivating the necessary ownership through stakeholder analysis is an essential ingredient of sustainable improvement efforts.

    Planning, Policy and Design 221 SEM A: PUBLIC POLICY

    Planning, Policy and Design 221 SEM A: PUBLIC POLICY

    Public policy investigates what government does or, in other words, the outcomes of decisions made at local, regional, national, and international levels of governance - as well as the consequences they bring about. We explore three central, interrelated questions regarding the nature of governmental decision-making processes having as their aim the enactment, implementation, and evaluation of public policy. These are: 1) what frameworks, explanatory theories, and ways of knowing illuminate how and why certain types of policies get made? 2) What is the role of the policy analyst - an academically trained professional - in describing, understanding, predicting, and designing policies? And, 3) what are the consequences of different policy designs on: public welfare and well-being, other areas of social discourse and interaction, and the concept of democracy itself?

    Mechanical and Aerospace Engineering 165: Advanced Manufacturing Choices

    Mechanical and Aerospace Engineering 165: Advanced Manufacturing Choices

    Manufacturing processes can be organized by considering the type of energy required to shape the work-piece. In this course, sources of energy considered for machining are mechanical used for cutting and shaping, heat energy such as in laser cutting, photochemical such as in photolithography, and chemical energy such as in electro chemical machining and chemical vapor deposition (CVD). Students, guided by product specifications and a design will decide: 1) When to apply mechanical machining vs. lithography based machining, 2) What type of mechanical machining and what type of lithography based machining to apply, 3) When to employ bottom-up vs. top-down manufacturing, 4) When to choose serial, batch or continuous manufacturing and 5) What rapid prototyping method to select. A logical decision tree will be presented to sort the machining options. Examples from a variety of products ranging in size from nanometers to centimeters will be considered.
