ziaiemehr, turan (author)There are places you have never been, yet you learn about them once you are there. There are also places you have never even dreamed possible, yet even after visiting them, your imagination never limits. One of these is Tbilisi.<br/>Persians, Byzantines, Ottomans, Russians, and Soviets all contributed to the construction of the image of Tbilisi...master thesis 2023

Lanfranco, Valerio (author), Luna-Navarro, Alessandra (author), Popescu, M.A. (author)The higher complexity of adaptive façades with respect to conventional static façades hinders their applicability to the built environment. To address this, passive solutions aim at lowering the number of components while preserving the benefits of these systems. In this paper the design of a two-component passive dynamic sunshade that combines...conference paper 2023

(author), Huang, Xinyan (author), Usmani, Asif Sohail (author), Chen, Guoming (author), Fu, Jianmin (author), Huang, Jiawei (author), Li, Junjie (author)Long short-term memory (LSTM) has been widely applied to real-time automated natural gas leak detection and localization. However, LSTM approach could not provide the interpretation that this leak position is localized instead of other positions. This study proposes a leakage detection and localization approach by integrating the attention...journal article 2023

(author)Chunking theory and previous eye-tracking studies suggest that expert chess players use peripheral vision to judge chess positions and determine the best moves to play. However, the role of peripheral vision in chess has largely been inferred rather than tested through controlled experimentation. In this study, we used a gaze-contingent paradigm...journal article 2023

Hai, R. (author), Koutras, C. (author), Quix, Christoph (author), Jarke, Matthias (author)Data lakes are becoming increasingly prevalent for Big Data management and data analytics. In contrast to traditional 'schema-on-write' approaches such as data warehouses, data lakes are repositories storing raw data in its original formats and providing a common access interface. Despite the strong interest raised from both academia and...journal article 2023

Breitwieser, Lukas (author), Hesam, A.S. (author), Rademakers, Fons (author), Luna, Juan Gómez (author), Mutlu, Onur (author)Agent-based modeling plays an essential role in gaining insights into biology, sociology, economics, and other fields. However, many existing agent-based simulation platforms are not suitable for large-scale studies due to the low performance of the underlying simulation engines. To overcome this limitation, we present a novel high...conference paper 2023

Liu, Q. (author), Ghodrat, S. (author), Huisman, G. (author), Jansen, K.M.B. (author)Devices delivering sophisticated and natural haptic feedback often encompass numerous mechanical elements, leading to increased sizes and wearability challenges. Shape memory alloys (SMAs) are lightweight, compact, and have high power-to-weight ratios, and thus can easily be embedded without affecting the overall device shapes. Here, a review...review 2023

Shahroodi, Taha (author), Miao, Michael (author), Zahedi, M.Z. (author), Wong, J.S.S.M. (author), Hamdioui, S. (author)The high execution time of DNA sequence alignment negatively affects many genomic studies that rely on sequence alignment results. Pre-alignment filtering was introduced as a step before alignment to reduce the execution time of short-read sequence alignment greatly. With its success, i.e., achieving high accuracy and thus removing...conference paper 2023

Chen, Qinyu (author), Chang, Yaoxing (author), Kim, Kwantae (author), Gao, C. (author), Liu, Shih Chii (author)Keyword spotting (KWS) is an important task on edge low-power audio devices. A typical edge KWS system consists of a front-end feature extractor which outputs mel-scale frequency cepstral coefficients (MFCC) features followed by a back-end neural network classifier. KWS edge designs aim for the best power-performance-area metrics. This work...conference paper 2023
