The Strong Ramsey game $\mathcal{R}(B,G)$ is a two player game with players $P_1$ and $P_2$, where $B$ and $G$ are $k$-uniform hypergraphs for some $k \geq 2$. $G$ is always finite, while $B$ may be infinite. $P_1$ and $P_2$ alternately color uncolored edges $e \in B$ in their respective color and $P_1$ begins. Whoever completes a monochromatic copy of $G$ in their own color first, wins the game. If no one claims a monochromatic copy of $G$ in a finite number of moves, the game is declared a draw. In this paper, we give an infinite set of 3-uniform hypergraphs $\{G_t\}_{t \geq 3}$, such that $P_2$ has a drawing strategy in the Strong Ramsey game $\mathcal{R}(K_{\aleph_0}^{(3)}, G_t)$. This improves a result by David, Hartarsky and Tiba.
Designing and validating efficient cache-coherent memory subsystems is a critical yet complex task in the development of modern multi-core system-on-chip architectures. Rhea is a unified framework that streamlines the design and system-level validation of RTL cache-coherent memory subsystems. On the design side, Rhea generates synthesizable, highly configurable RTL supporting various architectural parameters. On the validation side, Rhea integrates Verilator's cycle-accurate RTL simulation with gem5's full-system simulation, allowing realistic workloads and operating systems to run alongside the actual RTL under test. We apply Rhea to design MSI-based RTL memory subsystems with one and two levels of private caches and scaling up to sixteen cores. Their evaluation with 22 applications from state-of-the-art benchmark suites shows intermediate performance relative to gem5 Ruby's MI and MOESI models. The hybrid gem5-Verilator co-simulation flow incurs a moderate simulation overhead, up to 2.7 times compared to gem5 MI, but achieves higher fidelity by simulating real RTL hardware. This overhead decreases with scale, down to 1.6 times in sixteen-core scenarios. These results demonstrate Rhea's effectiveness and scalability in enabling fast development of RTL cache-coherent memory subsystem designs.
In recent years, integrating multimodal understanding and generation into a single unified model has emerged as a promising paradigm. While this approach achieves strong results in text-to-image (T2I) generation, it still struggles with precise image editing. We attribute this limitation to an imbalanced division of responsibilities. The understanding module primarily functions as a translator that encodes user instructions into semantic conditions, while the generation module must simultaneously act as designer and painter, inferring the original layout, identifying the target editing region, and rendering the new content. This imbalance is counterintuitive because the understanding module is typically trained with several times more data on complex reasoning tasks than the generation module. To address this issue, we introduce Draw-In-Mind (DIM), a dataset comprising two complementary subsets: (i) DIM-T2I, containing 14M long-context image-text pairs to enhance complex instruction comprehension; and (ii) DIM-Edit, consisting of 233K chain-of-thought imaginations generated by GPT-4o, serving as explicit design blueprints for image edits. We connect a frozen Qwen2.5-VL-3B with a trainable SANA1.5-1.6B via a lightweight two-layer MLP, and train it on the proposed DIM dataset, resulting in DIM-4.6B-T2I/Edit. Despite its modest parameter scale, DIM-4.6B-Edit achieves SOTA or competitive performance on the ImgEdit and GEdit-Bench benchmarks, outperforming much larger models such as UniWorld-V1 and Step1X-Edit. These findings demonstrate that explicitly assigning the design responsibility to the understanding module provides significant benefits for image editing. Our dataset and models are available at https://github.com/showlab/DIM.

A strengthened version of Harborth's well-known conjecture -- known as Kleber's conjecture -- states that every planar graph admits a planar straight-line drawing where every edge has integer length and each vertex is restricted to the integer grid. Positive results for Kleber's conjecture are known for planar 3-regular graphs, for planar graphs that have maximum degree 4, and for planar 3-trees. However, all but one of the existing results are existential and do not provide bounds on the required grid size. In this paper, we provide polynomial-time algorithms for computing crossing-free straight-line drawings of trees and cactus graphs with integer edge lengths and integer vertex position on polynomial-size integer grids.

<p class="5Abstract">Nowadays, the development of the job market is becoming increasingly competitive. Companies have various specific criteria for their prospective employees. In addition to having a degree, job candidates are also required to possess various soft skills. Therefore, Telkom University, through the Career Development Center (CDC), strives to prepare its students for employability. The Career Development Center (CDC) at Telkom University operates a website that serves as a digital platform for information sharing and interaction with both students and alumni. However, based on the results of the observation, issues were found on the website, including a user interface that is considered neither informative nor visually appealing. Considering the main function of this website is as a center for information and interaction among the academic community, a redesign of the CDC Telkom University website is necessary using a design thinking approach as the design method. Data was collected through observation and interviews, which were then analyzed using descriptive analysis methods to produce a user interface design that meets user needs. The result of this design process produced a new CDC website design in the form of a high-fidelity prototype that has undergone testing using the usability testing method and received positive feedback from end users. Through the redesign of this website's user interface, it is hoped that a good user experience will be achieved, allowing the Career Development Center of Telkom University to optimally convey information.</p>

Limited research has explored the delivery of sustainable design in higher education globally. Therefore, the aim of this paper is to investigate educational practices on the topic. Through an online survey, we investigated numerous aspects of units of study exposing topics related to sustainable design with a focus on contents, teaching methods and educational objectives. The survey was accessed by almost 400 educators in the field of sustainable design. The data show that a variety of teaching methods are used, with a critical role played by project-based learning in addition to traditional lectures. Most respondents rated all investigated intended learning outcomes as relevant or very relevant. In terms of contents and methods treated by the respondents, product eco-design and design for X are the most frequently taught methods. Educational approaches and teaching objectives are poorly affected by the discipline of the degree in which units of study are taught. In terms of contents, design degrees include approaches to sustainable design at the spatio-social level more frequently than engineering degrees do.
The following interview with Marisol Misenta, known professionally as Isol, discusses a number of ways in which the award-winning author, musician, and occasional comics artist from Argentina brings together music, singing, and narration through images in what she calls “una poción para soñar” (a concoction to dream about). The interview focuses on the so-called “discomic” Novela gráfica (Graphic Novel), released in 2014 by the Buenos Aires-based band SIMA, for which Isol served as lead vocalist, but also touches on some of the Argentine artist’s more recent collaborative and interdisciplinary art projects and performances. Topics include patterns in the relationship between comics and sound, the role of the reader-listener in experiencing and experimenting with the hybridization of music and comics with the discomic object, and how together comics and music (and sound by extension) enhance the audience experience.

Numerical optimization for the inverse design of photonic structures is a tool which is providing increasingly convincing results -- even though the wave nature of problems in photonics makes them particularly complex. In the meantime, the field of global optimization is rapidly evolving but is prone to reproducibility problems, making it harder to identify the right algorithms to use. This paper is thought as a tutorial on global optimization for photonic problems. We provide a general background on global optimization algorithms and a rigorous methodology for a physicist interested in using these tools -- especially in the context of inverse design. We suggest algorithms and provide explanations for their efficiency. We provide codes and examples as an illustration than can be run online, integrating quick simulation code and Nevergrad, a state-of-the-art benchmarking library. Finally, we show how physical intuition can be used to discuss optimization results and to determine whether the solutions are satisfactory or not.
Drawings represent ideas and concepts, not just an architectural project. The concept of the ‘Architecture of the Crowd’ establishes principles of an architecture in which people are protagonists. This architecture, in turn, relates in a harmonious way to the city, inviting people to enter, circulate, and interact with the space and other people, in a natural way. Fábio Moura Penteado’s architectural drawings representing these ideas and concepts were the focus of this study. The projects selected for analysis, dating back to the 1960s, are as follows: Araras Forum (1960), Campinas Coffee Museum (1960), Piracicaba Municipal Theater (1961), Campinas Opera Theater (1966), Campinas Cultural Coexistence Center (1967). Through the analysis of handmade perspective drawings, we can identify the presentation of ideas contained in their theoretical and conceptual discourse. The elements that define and compose the drawings are significant for the representation of their ideas: points of view from which the drawing was constructed; number of people, interacting, immobile or moving, and their location; automobiles and machinery; vegetation and landscape; representation of the accesses to the building with some welcoming element such as a marquee; indication of paths and routes. A point of view that has the ambition of a good, urban, modern society, from the perspective of ordinary people roaming the city and promoting meetings and events in a democratic, safe, and healthy environment.
In this essay, we readdress manual observational drawing, in drawing classes of graphic design undergraduate courses. Our teaching proposal supports itself on exploratory, and empirical research studies as well as cognitive applied research: 1st validating that - through copying-imitating other artists’ drawings, students can achieve creative outputs and develop other drawing fundamental skills identified as essential for graphic designers; 2nd how that can happen throughout - drawing from masters’ drawings -, suggesting teaching strategies, deducted from five identified cognitive mechanisms fostering creativity - ‘reinterpretation’ or ‘constraint relaxation’; ‘flexible abstraction’; ‘combinations’; ‘borrowing structure’ or ‘mapping’, and ‘find a new problem space’.
Quando nel 1996 ricevetti per la prima volta l’incarico dell’insegnamento di Tecniche di Rappresentazione dell’Architettura, realizzai una piccola dispensa con gli appunti del corso: per la copertina scelsi proprio la Tavola 4 dell’Architecture Civile di Jean-Jacques Lequeu. [continua a leggere]
In this article, we address data visualization as a political artifact in light of the work of the Observatory of Data and Statistics on Gender and Intersectionalities (ODEGI). We show how a feminist approach explores political dimensions in data and turns data visualization into a tool of subversion and resistance against the systems of oppression, in an unequal society like the Chilean. The reflections in this article seek to create dialogue around the question of how data visualization can be transformed into a tool of non-oppression and liberation, from a feminist approach. In line with this, the first part of the article provides a brief contextualization of the political and ethical attributes of data visualization. Then, we reflect on a framework that allows us to understand it as a feminist tool. We will finally delve into the ODEGI case and our use of data visualization to contribute to the fight against patriarchy and other systems of oppression, giving concrete examples of the categories of analysis we use in our design and decision processes.
La presente obra es una compilación de ensayos reunidos por la investigadora en letras modernas Ingrid Sánchez Téllez y el historiador Raúl Cera-Ochoa. Ellos convocaron a especialistas e investigadores(as) para el análisis y reflexión de teorías, experiencias, imágenes y relatos, cuyo eje central fuese desarrollar una colaboración desde el diálogo sobre los estudios de los cuerpos. Por tanto, el trabajo de compilación reúne trece textos con un interesante aporte al crecimiento del conocimiento en Latinoamérica para personas interesadas en pensar sobre este tema propuesto. Además, la obra genera espacios de interlocución entre académicos de diferentes disciplinas las cuales comparten diferentes puntos de vista sobre estudiar los cuerpos. En particular, considero que el fomento del libro permite la reconstrucción de distintas vías teóricas y metodológicas en los acercamientos investigativos hacia unas lógicas corporales.
<span id="docs-internal-guid-77ac10a0-7fff-767a-509e-61e7991ce58e">La sostenibilidad vinculada a los procesos de creación es una responsabilidad que los diseñadores deberían asumir. Desde el siglo pasado, grandes teóricos como Victor Papanek, han ayudado a sentar las bases del ecodiseño para establecer criterios de sostenibilidad medioambiental, facilitando la consolidación de la ética del diseño y su relación con las problemáticas sociales. En las primeras décadas del siglo XXI estos principios no sólo perduran, sino que se desarrollan y adaptan para atender a las nuevas exigencias desde las diferentes áreas del diseño. En este artículo revisamos cuándo se formulan dichos principios y cómo se aplican en la actualidad.</span>

Intelligent reflecting surface (IRS) has emerged as a key enabling technology to realize smart and reconfigurable radio environment for wireless communications, by digitally controlling the signal reflection via a large number of passive reflecting elements in real-time. Different from conventional wireless communication techniques that only adapt to but have no or limited control over dynamic wireless channels, IRS provides a new and cost-effective means to combat the wireless channel impairments in a proactive manner. However, despite its great potential, IRS faces new and unique challenges in its efficient integration into wireless communication systems, especially its channel estimation and passive beamforming design under various practical hardware constraints. In this paper, we provide a comprehensive survey on the up-to-date research in IRS-aided wireless communications, with an emphasis on the promising solutions to tackle practical design issues. Furthermore, we discuss new and emerging IRS architectures and applications as well as their practical design problems to motivate future research.
Personalized PageRank (PPR) is a graph algorithm that evaluates the importance of the surrounding nodes from a source node. Widely used in social network related applications such as recommender systems, PPR requires real-time responses (latency) for a better user experience. Existing works either focus on algorithmic optimization for improving precision while neglecting hardware implementations or focus on distributed global graph processing on large-scale systems for improving throughput rather than response time. Optimizing low-latency local PPR algorithm with a tight memory budget on edge devices remains unexplored. In this work, we propose a memory-efficient, low-latency PPR solution, namely MeLoPPR, with largely reduced memory requirement and a flexible trade-off between latency and precision. MeLoPPR is composed of stage decomposition and linear decomposition and exploits the node score sparsity: Through stage and linear decomposition, MeLoPPR breaks the computation on a large graph into a set of smaller sub-graphs, that significantly saves the computation memory; Through sparsity exploitation, MeLoPPR selectively chooses the sub-graphs that contribute the most to the precision to reduce the required computation. In addition, through software/hardware co-design, we propose a hardware implementation on a hybrid CPU and FPGA accelerating platform, that further speeds up the sub-graph computation. We evaluate the proposed MeLoPPR on memory-constrained devices including a personal laptop and Xilinx Kintex-7 KC705 FPGA using six real-world graphs. First, MeLoPPR demonstrates significant memory saving by 1.5x to 13.4x on CPU and 73x to 8699x on FPGA. Second, MeLoPPR allows flexible trade-offs between precision and execution time: when the precision is 80%, the speedup on CPU is up to 15x and up to 707x on FPGA; when the precision is around 90%, the speedup is up to 70x on FPGA.
In the modern days, manipulators are found in the automated assembly lines of industries that produce products in masses. These manipulators can be used only in one configuration, that is either serial or parallel. In this paper, a new module which has two degrees of freedom is introduced. By connecting the two and three modules in series, 4 and 6 DoF hybrid manipulators can be formed respectively. By erecting 3 modules in parallel and with some minor modifications, a 6 DoF parallel manipulator can be formed. Hence the manipulator is reconfigurable and can be used as hybrid or parallel manipulator by disassembling and assembling. The topology design, forward and inverse position analysis has been done for the two hybrid configurations and the parallel configuration. This manipulator can be used in industries where flexible manufacturing system is to be deployed. The three configurations of the parallel manipulator has been experimentally demonstrated using a graphical user interface (GUI) control through a computer.
