    Improved microphone array design with statistical speaker verification
    (Elsevier Ltd, 2021-04) Demir, Kadir Erdem; Eskil, Mustafa Taner
    Conventional microphone array implementations aim to lock onto a source with given location and if required, tracking it. It is a challenge to identify the intended source when the location of the source is unknown and interference exists in the same environment. In this study we combine speaker verification and microphone array processing techniques to localize and maximize gain on the intended speaker under the assumption of open acoustic field. We exploit the steering capability of the microphone array for more accurate speaker verification. Our first contribution is a new N-Gram based and computationally efficient feature for detecting an intended speaker. When the source and interference are localized, microphone array can be tuned further to reduce noise and increase the gain. Our second contribution is this integrated algorithm for speaker verification and localization. In the context of this study we developed SharpEar, an open source environment that simulates propagation of sound emanating from multiple sources. Our third and last contribution is this simulation environment, which is open source and available to researchers of the field.

    A review of recent innovations in remote health monitoring
    (Multidisciplinary Digital Publishing Institute (MDPI), 2023-12) Dalloul, Ahmed Hany; Miramirkhani, Farshad; Kouhalvandi, Lida
    The development of remote health monitoring systems has focused on enhancing healthcare services’ efficiency and quality, particularly in chronic disease management and elderly care. These systems employ a range of sensors and wearable devices to track patients’ health status and offer real-time feedback to healthcare providers. This facilitates prompt interventions and reduces hospitalization rates. The aim of this study is to explore the latest developments in the realm of remote health monitoring systems. In this paper, we explore a wide range of domains, spanning antenna designs, small implantable antennas, on-body wearable solutions, and adaptable detection and imaging systems. Our research also delves into the methodological approaches used in monitoring systems, including the analysis of channel characteristics, advancements in wireless capsule endoscopy, and insightful investigations into sensing and imaging techniques. These advancements hold the potential to improve the accuracy and efficiency of monitoring, ultimately contributing to enhanced health outcomes for patients.

    Localization based dynamics in the renewable energy sector
    (PressAcademia, 2019-07-30) Şerifsoy, Anıl
    Purpose- This research examinesthe ascend in utilizing localization as a strategy by Multinational Enterprisesin the energy sector. The sector is driven by governments, due to the ever-growing need for survivability and sustainability in a world increasingly dependent on energy. Methodology- In-depth interview is the chosen method to collect the critical opinions of small number of respondents who play a crucial role for decision-making in a leading company that prefers to utilize localization. This data is collated into a content analysis to determine the factors influencing it. Findings- Localization from a global company engaging in renewable energy sector can be desirable, and indeed, profitable, insomuch as the right conditions outlined by the interviewees are created. Conclusion- It is the intent of the author to build the first step of a guide to attract more positive attention from MNEs to encourage more technology transfer.

    Design of quadruped robot for autonomous exploration and earthquake rescue
    (Işık Üniversitesi, Lisansüstü Eğitim Enstitüsü, 2025-09-17) Baqutyan, Faisal Ali Hasan; Köprü, Ramazan; Işık Üniversitesi, Lisansüstü Eğitim Enstitüsü, Elektronik Mühendisliği Yüksek Lisans Programı; Işık University, School of Graduate Studies, Electronics Engineering M.S. Program
    Son yıllarda, tekerlekli robotlar için sorun olabilecek zorlu arazilerde yürüme kabiliyetlerine sahip oldukları için dört ayaklı robotlar büyük ilgi görmüştür. Bu da onları afet ortamlarında keşif ve Arama-Kurtarma (SAR) operasyonları için oldukça uygun hale getirmektedir. Bu tez, algılama görevlerini yerine getirirken yürüyebilen, uygun maliyetli, otonom bir dört ayaklı robotun tasarımını sunmaktadır. Araştırmanın iki ana odağı mekanik tasarım ve elektronik tasarımdır. Mekanik yön, yapısal çerçeveyi, çalışma mekanizmasını, ters kinematiği ve özel bir yürüyüş modelini içerir. Diğer yandan, elektronik sistem tasarımı, otonom navigasyon, algılama ve kontrolü sağlamak için bir ESP32 mikrodenetleyici ve ESP32-CAM'i çeşitli sensörler ve aktüatörlerle entegre etmektedir. Yazılım sistemi, ultrasonik sensörler kullanarak gerçek zamanlı engel tespiti, acil durum sesli uyarısı olan bir MQ sensörü kullanarak gaz izleme ve video akışı sunmaktadır. Ayrıca, haritalama, yerelleştirme ve yol planlama dahil olmak üzere gelişmiş otonom keşif için bir 2D RPLIDAR A1 sensörü entegre edilmiştir. Bu yetenekler, görselleştirme için RViz ve gerçekçi simülasyon için Gazebo dahil olmak üzere Robot İşletim Sistemi (ROS) kullanılarak uygulanmış ve test edilmiştir. Bu iş birliği çalışmaları, düşük maliyetli dört ayaklı robotların gerçek dünya acil durum senaryolarında konuşlandırılma olasılığını kanıtlamaktadır. Donanım, yazılım ve simülasyonun entegrasyonu, tasarımı doğrulamakla kalmayıp aynı zamanda arama kurtarma görevlerinde daha fazla özerklik ve sağlamlığın sürekli geliştirilmesi için de olanaklar sunmaktadır.
