This document describes research into developing customizable large print maps for individuals with low vision. It discusses an algorithm for automatically labeling streets on Scalable Vector Graphics (SVG) maps produced by the Tac7le Map Automated Produc7on (TMAP) soHware. The algorithm aims to address issues identified in previous studies, such as small street names, mul7ple street colors, and too much visual detail. The goal is to allow low vision users to customize map features like font size, color, and amount of informa7on displayed.
Robot-Assisted Wayfinding for the Visually Impaired in Structured Indoor Envi...Vladimir Kulyukin
We present a robot-assisted wayfinding system for the visually impaired
in structured indoor environments. The system consists of a mobile robotic guide
and small passive RFID sensors embedded in the environment. The system is intended
for use in indoor environments, such as office buildings, supermarkets and
airports. We describe how the system was deployed in two indoor environments
and evaluated by visually impaired participants in a series of pilot experiments. We
analyze the system’s successes and failures and outline our plans for future research
and development.
Eyes-Free Barcode Localization and Decoding for Visually Impaired Mobile Phon...Vladimir Kulyukin
An eyes-free barcode localization and decoding method is presented that enables visually impaired (VI) mobile phone users to decode MSI (Modified Plessy) barcodes on shelves and UPC barcodes on individual boxes, cans, and bottles. Simple and efficient barcode localization and decoding techniques are augmented with an interactive haptic feedback loop that allows the VI user to align the phone’s camera with a fixed surface in the pitch and yaw planes. The method is implemented on a Google Nexus One smart phone running Android 2.1. A laboratory study is presented in which the method was evaluated by one VI and four blindfolded sighted participants.
Efficiency or Quality of Experience: A Laboratory Study of Three Eyes- Free T...Vladimir Kulyukin
A growing number of individuals who are blind or visually impaired is using smartphones in their daily
activities. The touchscreen is a standard component of smartphones. While benefitting people with low vision by enhancing control of the text style and color and the size of images and text, the touchscreen has the downside for visually
impaired users in that physical buttons for input of command selection and text entry are replaced with the touchscreen’s soft buttons. To overcome this limitation, we are investigating eyes-free approaches to using the smartphone’s touchscreen for information browsing. In this article, we present a laboratory study of three eyes-free touchscreen user
interfaces for browsing menu hierarchies. Our findings indicate that quality of experience and familiarity may be as important as the time efficiency of completing tasks.
User Intent Communication in Robot-Assisted Shopping for the BlindVladimir Kulyukin
The research reported in this chapter describes our work on robot-assisted shopping for the blind. In our previous research, we developed RoboCart, a robotic shopping cart for the visually impaired. RoboCart's operation includes four steps: 1) the blind shopper (henceforth the shopper) selects a
product; 2) the robot guides the shopper to the shelf with the product; 3) the shopper finds
the product on the shelf, places it in the basket mounted on the robot, and either selects
another product or asks the robot to take him to a cash register; 4) the robot guides the
shopper to the cash register and then to the exit.
Steps 2, 3, and 4 were addressed in our previous publications . In this paper, we focus on Step 1 that requires
the shopper to select a product from the repository of thousands of products, thereby
communicating the next target destination to RobotCart. This task becomes time critical in
opportunistic grocery shopping when the shopper does not have a prepared list of products.
If the shopper is stranded at a location in the supermarket selecting a product, the shopper
may feel uncomfortable or may negatively affect the shopper traffic.
An introduction to GIS Data Types. Strengths and weaknesses of raster and vector data are discussed. Also covered is the importance of topology. Concludes with a discussion of the vector-based format of OpenStreetMap data.

TEXT EXTRACTION FROM RASTER MAPS USING COLOR SPACE QUANTIZATIONcsandit
Maps convey valuable information by relating names to their positions. In this paper we present
a new method for text extraction from raster maps using color space quantization. Previously,
most researches in this field were focused on Latin texts and the results for Persian or Arabic
texts were poor. In our proposed method we use a Mean-Shift algorithm with proper parameter
adjustment and consequently, we apply color transformation to make the maps ready for KMeans
algorithm which quantizes the colors in maps to six levels. By comparing to a threshold
the text layer candidates are then limited to three. The best layer can afterwards be chosen by
user. This method is independent of font size, direction and the color of the text and can find
both Latin and Persian/Arabic texts in maps. Experimental results show a significant
improvement in Persian text extraction.

Digitizing Buzzing Signals into A440 Piano Note Sequences and Estimating Forager Traffic Levels from Images in Solar-Powered, Electronic Beehive Monitoring
Many problems in information retrieval and related fields depend on a reliable measure of the distance or similarity between objects that, most frequently, are represented
as vectors. This paper considers vectors of bits. Such data structures implement entities as diverse as bitmaps that indicate the occurrences of terms and bitstrings indicating the presence
of edges in images. For such applications, a popular distance measure is the Hamming distance. The value of the Hamming distance for information retrieval applications is limited by the
fact that it counts only exact matches, whereas in information retrieval, corresponding bits that are close by can still be considered to be almost identical. We define a "Generalized
Hamming distance" that extends the Hamming concept to give partial credit for near misses, and suggest a dynamic programming algorithm that permits it to be computed efficiently.
We envision many uses for such a measure. In this paper we define and prove some basic properties of the :Generalized Hamming distance," and illustrate its use in the area of object
recognition. We evaluate our implementation in a series of experiments, using autonomous robots to test the measure's effectiveness in relating similar bitstrings.
Adapting Measures of Clumping Strength to Assess Term-Term SimilarityVladimir Kulyukin
Automated information retrieval relies heavily on statistical regularities that emerge as terms are deposited to produce text. This paper examines statistical patterns expected of a pair of
terms that are semantically related to each other. Guided by a conceptualization of the text generation process, we derive measures of how tightly two terms are semantically associated.
Our main objective is to probe whether such measures yields reasonable results. Specifically, we examine how the tendency of a content bearing term to clump, as quantified by previously
developed measures of term clumping, is influenced by the presence of other terms. This
approach allows us to present a toolkit from which a range of measures can be constructed.
As an illustration, one of several suggested measures is evaluated on a large text corpus built from an on-line encyclopedia.

Toward Blind Travel Support through Verbal Route Directions: A Path Inference...Vladimir Kulyukin
The work presented in this article continues our investigation of such assisted navigation solutions where the
main emphasis is placed not on sensor sets or sensor fusion algorithms but on the ability of the travelers to interpret and
contextualize verbal route directions en route. This work contributes to our investigation of the research hypothesis that
we have formulated and partially validated in our previous studies: if a route is verbally described in sufficient and
appropriate amount of detail, independent VI travelers can use their O&M and problem solving skills to successfully
follow the route without any wearable sensors or sensors embedded in the environment.
In this investigation, we temporarily put aside the issue of how VI and blind travelers successfully interpret route
directions en route and tackle the question of how those route directions can be created, generated, and maintained by
online communities. In particular, we focus on the automation of path inference and present an algorithm that may be used
as part of the background computation of VGI sites to find new paths in the previous route directions written by online
community members, generate new route descriptions from them, and post them for subsequent community editing.

DERIVATION OF MODIFIED BERNOULLI EQUATION WITH VISCOUS EFFECTS AND TERMINAL V...Wasswaderrick3
In this book, we use conservation of energy techniques on a fluid element to derive the Modified Bernoulli equation of flow with viscous or friction effects. We derive the general equation of flow/ velocity and then from this we derive the Pouiselle flow equation, the transition flow equation and the turbulent flow equation. In the situations where there are no viscous effects , the equation reduces to the Bernoulli equation. From experimental results, we are able to include other terms in the Bernoulli equation. We also look at cases where pressure gradients exist. We use the Modified Bernoulli equation to derive equations of flow rate for pipes of different cross sectional areas connected together. We also extend our techniques of energy conservation to a sphere falling in a viscous medium under the effect of gravity. We demonstrate Stokes equation of terminal velocity and turbulent flow equation. We look at a way of calculating the time taken for a body to fall in a viscous medium. We also look at the general equation of terminal velocity.

Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
