Abstract:
AbstractThe value of sketching in engineering design has been widely documented. This paper reviews trends in recent studies on sketching in engineering design and focuses on the encouragement of sketching. The authors present three experimental studies on sketching that look at (1) sketching assignments and their motivation, (2) the impact of a sketching lesson, and (3) the use of Smartpen technology to record sketching; overall these studies address the research question: Can sketching frequency be influenced in engineering education? Influencing sketching frequency is accomplished through motivation, learning, and use of technology for sketching, respectively. Results indicate that these three elements contribute to the encouragement of sketching in engineering design.

Abstract:
Freehand sketching is a fundamental skill in mechanical engineering and many other engineering disciplines. It not only serves as a communication tool among engineers, but plays a critical role in engineering design and problem solving. However, as computer-aided drafting has replaced traditional drawing classes nowadays, the training of students’ freehand sketching skills has been almost completely eliminated in modern engineering curricula. This paper describes the attributes of freehand sketching and its roles in several essential aspects of engineering; in particular, in its roles in problem solving, of which current literature has ignored. Representative examples are provided to show students’ freehand sketching skills in problem solving in a foundational undergraduate mechanical engineering course. Pedagogical suggestions are made on how to teach freehand sketching to engineering students.

Abstract:
Previous studies have demonstrated the importance of sketching in design cognition, particularly in the early stages of engineering design. The goal of this preliminary study is to consider the role of a designer’s sketching ability and to examine the potential link between sketching skill and measures of engineering design performance. Sketching ability was evaluated on three distinct aspects relevant to engineering design: visual recall, rendering, and novel visualization. These evaluations were correlated with each other and with measures for sketch fluency, reviewer ranking, and design project outcome. The results of this study suggest that sketching skill is not comprehensive nor is it solely task based. Rather, a designer’s sketching ability lies between these two poles. Positive correlations were found between the quantity of sketches produced and two of the sketching skills that emphasize drawing facility, but a negative correlation was found between sketch quantity and a skill related to mechanism visualization. No conclusive correlations were found between the sketching skills and design outcome and reviewer ranking. This study's findings suggest an important interplay between a designer's ability to sketch and their ability to visualize in their heads or through prototypes. Results also suggest that designers who are given sketch instruction tended to draw more overall.

Abstract:
Sketching in general engineering and science has been “outmanoeuvred” by computer graphics while still holding on in architectural engineering as a tool to think about spatial relationships, allowing the students to develop conceptual designs quicker than any CAD. Moreover, a recent paper reported that sketching helped students in geology develop critical thinking skills. Based on students’ feedback, it was concluded that it led to a deeper understanding of important concepts. Should it surprise us that psychological research shows that sketching facilitates inference, discovery and learning? This paper presents a model for creating and assessing assignments that uses engineering sketching to teach and learn in a second year course at UNSW, CVEN2101-Engineering Construction. The class focuses on studying key principles related to the safe and effective utilization of construction equipment such as trucks, excavators, cranes and temporary structures. Students faced the challenge to investigate how the physics and math relate to digging, lifting and the creation of large forces while keeping labourers safe. The concept of forensic engineering had to be used to study the cause of accidents. The developed model includes various measurements and proper motion paths, in an attempt to quantify the level of understanding. It is felt, that based on the findings of this study, that engineering sketching not only allows inventing new mechanisms, as Leonardo da Vinci did, but equally important, provides a valuable and reliable tool to teach and learn construction engineering.

Abstract:
This study proposes the introduction of reverse engineering technology into a graphic workshop in the discipline «Engineering Graphics». The purpose of this study was the scientific and methodological substantiation of the need to use reverse engineering in the methodology of teaching engineering graphics. The article considers the concept of «reverse engineering», its application for solving engineering problems and in the educational process. It is shown that reverse engineering of a part and a sketch of a part are used in solving issues of production organization, in pilot production, repair and other cases, to solve similar and sometimes identical engineering problems. It has been suggested that the technology of reverse engineering in production conditions can replace the function of sketching a part. In the educational process for some areas of training, it is proposed to consider reverse engineering of the part in addition to the topic “part sketch”. A comparison is made of the use of reverse engineering technology and part sketching to solve the engineering problem of obtaining a three-dimensional digital model of a part. As part of the educational process, it is proposed to consider it as a situational or complex task. The scientific and methodological substantiation of the need to use reverse engineering in the methodology of teaching engineering graphics is based on the results of the experiment, which included parallel operations of reverse engineering and part sketching.

Abstract:
We investigated whether and, if so, for what reason, problem solving in design may be supported by “external approaches”, especially sketching. An experimental study with 74 undergraduates analyses whether sketching before and/or during Computer Aided Design (CAD) improves the quality of solutions, reduces time taken as well as the number of processing steps in CAD, by offering the opportunity to test the functions designed. In spite of additional sketching time, the total time taken is significantly reduced for the more complex task analysed. This can be explained by the reduction of the number of processing steps needed. These experimental results verify the perceived utility of sketching before and during Computer Aided Design, confirmed in a questionnaire study with more than 100 experienced engineering designers.

Often in computer science, graphs are used to represent metrics: the nodes represent "locations," and the edges represent connectivity between locations. The salient properties of such a graph are the shortest path distances between its nodes - that is, the minimum length of a path from each point A to each point B, capturing the time or resource cost of travelling from one place to another in the space represented by the graph. There are plenty of nice algorithms and structure theorems that are used to understand or analyze shortest path distances. However, in the modern computing, we sometimes have to handle spaces that are too enormous to be efficiently handled by these classic methods. When this happens, it is often useful to "sketch" these enormous spaces, designing a graph or data structure that approximately encodes the distances of the original network, but in much smaller space. This dissertation is about the design of these graph sketches that encode distances. Some of the content will cover upper bounds: we will demonstrate some new ways to make sketches, and we will prove things about the tradeoff between the size of these sketches and their approximation error. Some of the content will cover lower bounds: we will design some very particular graphs, and we will prove that a certain size vs error tradeoff can't be achieved any sketch on these graphs. We will do this for a few different reasonable notions of "approximation" of distances. We will also consider some of these settings in the fault-tolerant model, where we imagine that nodes or edges of the graph can spontaneously "fail," and we want our sketches to be strongly robust to these failures.

Abstract:
The process of musical composition is sometimes conceived of as an individual, internal, cognitive process in which notation plays a passive role of transmitting or recording musical ideas. This thesis questions the role played by representations in musical composition practices. We begin by tracing how, historically, compositional practices have co-evolved with musical representations and technologies for music production. We present case studies to show that the use of graphical sketches is a characteristic feature of the early stages of musical composition and that this practice recurs across musical genres ranging from classical music to contemporary electroacoustic composition. We describe the processes involved in sketching activities within the framework of distributed cognition and distinguish an intermediate representational role for sketches that is different from what is ‘in the head’ of the composer and from the functions of more formal musical notations. Using evidences from the case studies, we argue in particular that as in other creative design processes, sketches provide strategically ambiguous, heterogeneous forms of representation that exploit vagueness, indeterminacy and inconsistency in the development of musical ideas. Building on this analysis of the functions of sketching we describe the design and implementation of a new tool, the Music Sketcher, which attempts to provide more under-specified and flexible forms of ‘sketch’ representation than are possible with contemporary composition tools. This tool is evaluated through a series of case studies which explore how the representations constructed with the tool are interpreted and what role they play in the compositional process. We show that the program provides a similar level of vagueness to pen and paper, while also facilitating re-representation and re-interpretation, thus helping bridge the gap between early representations and later stages of commitment.

Sketching, although deceptively simple and seemingly primitive, is a powerful paradigm for designing and understanding many types of engineering systems. Many problem domains, such as designing electrical circuits, developing flow charts, and modeling simple mechanical devices, rely heavily on the ability to produce sketches efficiently in order to bring out the most salient features. Engineers working in these domains usually rely on pen and paper to generate their design sketches. They do this because more advanced technologies (such as notebook computers) are often unavailable, hard to learn, or cumbersome. It is important for engineers to collaborate with their colleagues while working on their sketches. Unfortunately, collaboration on sketches that exist only as pen and paper often proves to be tedious, requiring a minimum of a fax machine and scanner. Engineers could benefit from a more efficient means of collaboration when dealing with pen and paper sketches. The technology exists to improve the current situation and make pen and paper sketches a more effective medium for collaborative design. This thesis presents an implementation of a system that achieves three goals. First, the system allows two users to collaborate on the production of a sketch in much the same way they would collaborate when composing a document (with one user composing a sketch, then accepting or rejecting the changes of his collaborator).
(cont.) Second, it allows users to watch a collaborator's additions play in real time, like watching a movie. And finally, it links the sketch recognition and simulation software developed by the Design Rationale Group at MIT with a simple pen and paper interface, allowing engineers to run simulations of their design sketches. These goals are achieved by using a commercial pen produced by the Anoto Group that is capable of storing the strokes it draws. In essence, the user creates both a hard and soft copy of the sketch simultaneously, and can share the soft copy with any collaborator. Using this model of production, sketches can be collaboratively generated, edited, and reviewed quickly and easily, all using only a pen, paper, and a standard printer.

A sketch of a dataset is a small-space data structure supporting some prespecified set of queries (and possibly updates) while consuming space substantially sublinear in the space required to actually store all the data. Furthermore, it is often desirable, or required by the application, that the sketch itself be computable by a small-space algorithm given just one pass over the data, a so-called streaming algorithm. Sketching and streaming have found numerous applications in network traffic monitoring, data mining, trend detection, sensor networks, and databases. In this thesis, I describe several new contributions in the area of sketching and streaming algorithms. The first space-optimal streaming algorithm for the distinct elements problem. Our algorithm also achieves 0(1) update and reporting times. A streaming algorithm for Hamming norm estimation in the turnstile model which achieves the best known space complexity. The first space-optimal algorithm for pth moment estimation in turnstile streams for 0 < p < 2, with matching lower bounds, and another space-optimal algorithm which also has a fast O(log²(1/[epsilon]) log log(1[epsilon])) update time for (1+/-[epsilon])- approximation. A general reduction from empirical entropy estimation in turnstile streams to moment estimation, providing the only known near-optimal space-complexity upper bound for this problem. A proof of the Johnson-Lindenstrauss lemma where every matrix in the support of the embedding distribution is much sparser than previous known constructions. In particular, to achieve distortion (1+/-[epsilon]) with probability 1-[delta], we embed into optimal dimension 0([epsilon]-²log(1/[delta])) and such that every matrix in the support of the distribution has 0([epsilon]-¹ log(1/[delta])) non-zero entries per column.

Given n positive integers, the Modular Subset Sum problem asks if a subset adds up to a given target t modulo a given integer m. This is a natural generalization of the Subset Sum problem (where m = + [infinity symbol]) with ties to additive combinatorics and cryptography. The non-modular case was long known to be NP-complete but to admit pseudo-polynomial time algorithms and, recently, algorithms running in near-linear pseudo-polynomial time were developed [9, 211. For the modular case, however, the best known algorithm by Koiliaris and Xu [21] runs in time 0̃ (m⁵/⁴). In this thesis we tackle this problem by devising a faster algorithm for the Modular Subset Sum problem, running in 0̃(m) randomized time, which matches a recent conditional lower bound of [1] based on the Strong Exponential Time Hypothesis. Interestingly, in contrast to most previous results on Subset Sum, our algorithm does not use the Fast Fourier Transform. Instead, it is able to simulate the "textbook" Dynamic Programming algorithm much faster, using ideas from linear sketching. This is one of the first applications of sketching-based techniques to obtain fast algorithms for exact combinatorial problems in an offline setting.

We study two fundamental problems that involve massive high-dimensional datasets: approximate near neighbor search (ANN) and sketching. We obtain a number of new results including: ' An algorithm for the ANN problem over the ℓ₁ and ℓ₂ distances that, for the first time, improves upon the Locality-Sensitive Hashing (LSH) framework. The key new insight is to use random space partitions that depend on the dataset. ' An implementation of the core component of the above algorithm, which is released as FALCONN: a new C++ library for high-dimensional similarity search. ' An efficient algorithm for the ANN problem over any distance that can be expressed as a symmetric norm. ' For norms, we establish the equivalence between the existence of short and accurate sketches and good embeddings into ℓp spaces for 0 < p by Ilya Razenshteyn.

Computers should be able to assist an engineer or designer at all stages of design without chasing the engineer away or frustrating her. In order for this to occur, the computer needs to be able to understand what the engineer is doing and provide unobtrusive help. Furthermore the engineer needs to be able to interact with the computer in a natural manner. To support this design methodology I implement a foundation on which a programmer can make such applications. I provide two illustrative applications which demonstrate the foundation's power.

Researchers are generating single-cell RNA sequencing (scRNA-seq) profiles of diverse biological systems [1]-[7] and every cell type in the human body [8] at an unprecedented scale, with scRNA-seq experiments regularly profiling gene expression in hundreds of thousands or even millions of cells [9]. Leveraging this data to gain unprecedented insight into biology and disease requires algorithms that can scale to the tremendous amount of data being generated and can integrate information across multiple experiments, laboratories, and technologies. Here, we present two algorithms that aim to aid researchers in gaining better insight from scRNA-seq data sets. The first, Scanorama, inspired by algorithms for panorama stitching, achieves accurate integration of heterogeneous scRNA-seq data sets, which we use to integrate a number of large and complex collections of data sets. The second algorithm, geometric sketching, is a sampling approach that aims to evenly cover the low-dimensional manifold spanned by the cells to capture more of the rare transcriptional structure than would uniform subsampling with equal probability for each cell, obtaining sketches that better capture the transcriptional heterogeneity of the original data. Moreover, geometric sketching can be used to improve the computational efficiency of algorithms for single-cell integration, including Scanorama. We anticipate that both algorithms will play an important role in the analysis and interpretation of large-scale single-cell transcriptomic data sets.

Abstract:
AbstractWe present a novel approach for resolving numerical program sketches under Boolean and quantitative objectives. The input is a program sketch, which represents a partial program with missing numerical parameters (holes). The aim is to automatically synthesize values for the parameters, such that the resulting complete program satisfies: a Boolean (qualitative) specification given in the form of assertions; and a quantitative specification that estimates the number of execution steps to termination and which the synthesizer is expected to optimize.To address the above quantitative sketching problem, we encode a program sketch as a program family (a.k.a. software product line) and analyze it by the specifically designed lifted analysis algorithms based on abstract interpretation. In particular, we use a combination of forward (numerical) and backward (termination) lifted analysis of program families to find the variants (family members) that satisfy all assertions, and moreover are optimal with respect to the given quantitative objective. Such obtained variants represent “correct & optimal” sketch realizations.We present a prototype implementation of our approach within the FamilySketcher tool for resolving C sketches with numerical types. We have evaluated our approach on a set of benchmarks, and experimental results confirm the effectiveness of our approach.

Abstract:
As Computer-Aided Design software has become more advanced, the use of hand-drawn engineering drawings has greatly diminished. This reduction has led to free-hand sketching becoming less emphasized in engineering education. While many engineering curriculums formerly included courses dedicated entirely to sketching and hand drafting, these topics are no longer addressed by most current curriculums. However, it has been observed that sketching has many benefits including improved communication in the design process, idea generation exercises, and visualizing design ideas in three-dimensional space. While isometric sketching has long been the preferred method in engineering curriculums, there are benefits of teaching perspective sketching including the creation of more realistic sketches for communication and idea generation. This paper presents the development of a perspective-based sketching curriculum and the study of how this method compares to more traditional methods of teaching sketching to students in a freshman level engineering graphics course. The results show that the perspective-based sketching method leads to equivalent gains in spatial visualization skills and final design self-efficacy as the traditional method of teaching hand sketching. While maintaining these skills, the new method also taught students additional skills. Through surveys and interviews, the students expressed that these skills would be useful to them in their future coursework and careers.

Abstract:
Many studies have shown the importance of sketching skill in engineering design, more specifically in the conceptual design phase. Yet, engineering students today clearly have a preference when it comes to design and sketching is not often included in their visual documentation tool kit. The reasons may be that first, today’s contemporary engineering course plan does not include a sketch training course leaving students feeling inadequate to the task. Secondly in such a demanding fast passed global economy, time is of the essence and tools such as CAD, Pro-E, and Inventor offer quick solutions to design problems. Overall students do not appear to appreciate the value of sketching in the design process. This must be changed. This paper presents the results of a study to intervene with the purpose of influencing student use of sketching during design in a senior capstone course at The University of Maryland. The students sketches are reviewed pre and post a specific lesson based on the importance of sketching in mechanical design. This sketching importance lesson changed the content of the sketches when compared to a control group.

Abstract:
Sketching is an activity that takes place throughout the engineering design process, and is often linked to design cognition. This preliminary study identifies different skills that contribute to a designer’s sketching ability and explores how those skills might be related to sketch fluency and design outcome. A positive correlation was found between the quantity of sketches produced and sketch skills that emphasize drawing facility, but a negative correlation was found between sketch quantity and a skill related to mechanism visualization. Sketching is sometimes considered a generic skill, but this study suggests that there are differences among the different types of sketching skills in the context of engineering design. No notable relationship was found between sketching ability and design outcome. Results also suggest that students provided with explicit instruction in sketching tended to draw more overall, although there are likely many other factors involved.

Abstract:
The ability to visually communicate ideas and the willingness to generate free-hand sketches are critical skills for engineers. With the advent of CAD, schools no longer teach drafting, prompting a concern over the lost art of free-hand sketching. Recent empirical data from senior design indicates they do not sketch until forced to do so and this agrees with much anecdotal data. This paper describes a novel approach to teaching sketching in a freshman CAD course using an industrial design methodology during the first six weeks of the semester. As expected, sketching skills improved, but there was concern that this may be at the expense of spatial visualization skills typically taught through isometric drawing. Spatial visualization skills are critical for engineers and have been linked to success in engineering programs. The current study measured spatial visualization skills at three points during the freshman CAD course. The industrial design approach to perspective sketching led to significant improvements in spatial visualization scores that were not statistically different from the more traditional approach within engineering. Overall, it was the sketching portion, not the CAD, that significantly improved the students’ spatial visualization scores. Including free-hand sketching in engineering not only improves sketching ability, but also improves the spatial visualization skills crucial for success in engineering in a way that CAD alone does not.

Abstract:
While much prior work has been done regarding sketching and its impact on design and a few on how to train engineers to sketch, there have been no prior studies in engineering to reduce inhibition to frequent sketching. This paper describes a sketching intervention developed from art teaching aimed at reducing inhibition to sketching and a study to evaluate its effectiveness. In the study, students (n = 55) were tested with pre-mid-post assessments consisting of a mechanical, organic, and design-oriented sketching task and a TLX survey measuring the level of difficulty. The study found that the students overwhelmingly reported their inhibition was lowered, but the short-term TLX data suggested inhibition was higher. However, the TLX data showed a longterm decrease in inhibition-related measures, perhaps suggesting that long-term encouragement to sketch is effective in reducing inhibition to sketch. These results tentatively suggest that sketch inhibition is reduced by actively promoting creativity and sketching, some use of the activities presented here, and by deemphasizing the importance of higher-level skills such as perspective drawing.
