Argus Technology Inc. aims to develop a more intelligent, adaptive and user-friendly identity and access management system by using its competencies in artificial intelligence, informatics and cybersecurity. This will help the company gain a competitive advantage in both local and global markets and consolidate its leadership in the sector.
The aim of the project is to develop remotely controlled unmanned aerial vehicles designed for special purposes and capable of vertical or horizontal take-off and landing. The project output will be a multi-purpose drone aircraft with a hybrid power system that can perform autonomous vertical and horizontal take-off and landing. Sensors and actuators can be placed on the drone to be developed for different tasks such as mining, mapping, and spraying. In this way, very different studies such as mining, mapping, observation, and spraying can be carried out in very remote areas with high access costs. The product will be developed with superior features compared to other vehicles in the UAV-2 class.
Autononym ensures robust data privacy, fosters compliance and expands research scopes through AI-driven anonymization, enabling secure cross-sector data sharing, user transparency and global collaborations while maintaining data's inherent value. Designed for institutions such as the Ministry of Health that manage large amounts of user or citizen data, this platform ensures confidentiality by identifying and anonymizing personal data shared for research purposes. Autononym navigate the complex data landscape, maintaining research value while safeguarding individual identities, a crucial step in today's data-driven world fraught with confidentiality concerns.
In the scope of the project, in three urban areas, Mardin-(Csa), Eskişehir-(Bsk) and Sivas-(Dsb), which have been chosen based on climate classification in Turkey, annual mean temperature, annual mean temperature change, energy consumption and population data; (i)the local climate zone approach will be used to classify the characteristics of the urban built environment and topography, (ii)the relationship between LCZ, urban morphology, planning parameters and land surface temperatures in these cities with different and similar climate types will be revealed quantitatively, (iii)the effects of different planning and design strategies to decrease the UHI effect in these cities will be revealed through modeling. Data will be visualized with the software to be developed. The project will contribute to both national and international UHI literature, also it will contribute to the LCZ classification system with a theoretically and empirically original study.
Predis advanced anomaly detection capacity brings innovative methods to population health strategies. It reveals hidden patterns using various information, such as prescriptions, medication movements or disease data, alongside analysis based on geographic information systems (GIS). These approaches offer insights across various geographic scopes, from the national scale to the smallest unit. Predis empowers healthcare providers and authorities to improve healthcare outcomes for the entire population and a healthier future.
This project aims to utilize artificial intelligence techniques to enhance the indexing, archiving, and accessibility of video content. Targeting sectors like news agencies, TV channels, educational institutions, and security, it introduces innovations such as semantic search, relational search, similarity analysis, and multimodal analysis to modernize video archiving processes. This will enable faster and more efficient access to information, adding value to industries. The project will group videos by similarities, recognize sounds, objects, and people, and integrate visual, auditory, and text-based data for a comprehensive solution, offering significant improvements over traditional methods.
Bad weather conditions, low visibility, environmental factors or problems that may occur in the navigation system pose serious risks for vertical take-off/landing aircraft. When it is considered that such aircraft also land/take-off on mobile and narrow-space land and sea platforms, especially in military operations, the importance of the system to be developed becomes even more evident. In this context, the aim of the project is to develop an original landing area detection and evaluation system domestically with national resources in order to minimize the accidents that may occur during the landing/take-off of manned or unmanned aerial vehicles that make vertical take-off/landing in military and civil aviation and thus to prevent loss of life and property.
The project aims to revolutionise digital twin technology through IoDT2, an open framework that addresses scalability and collaboration challenges. By leveraging serverless edge computing and digital twin-centric networking, IoDT2 enables seamless sharing of distributed models and real-time responsiveness. This approach enhances interoperability, optimises performance, and simplifies digital twin creation, benefiting various industries and promoting widespread adoption.
