Finally, the algorithm removes superfluous communities in a post-processing step. We inspect the algorithm’s performance on a set of host-parasite networks and show the correlation between mean community size and the discrepancy nestedness measure.

This hierarchical protocol aggregates and forwards data from cluster members to a fixed sink node using the cluster head feature of the nodes. We propose a new family of routing mechanisms called CB-LEACH by introducing movement possibility to the sink node and balancing the cluster head election decision based on the distances between the nodes and on the remaining energy of the potential cluster head candidates.

It is also expected not just very expensive to do such kinds of experiments, but these problematic conditions are also lead to dangerous traffic situations at the same time. We made an effort to put these kinds of studies into a cost-effective and safe model-scale environment.

Our proposed method is based on a fast neural network architecture using YOLO layers to detect regions. Our experiments demonstrate the capabilities and detection accuracy of the designed neural network, called anomalyNet, with the complete training and evaluation process.

With sensors and artificial intelligence, the autonomous vehicle tries to find the optimal decision as close as possible to the appropriate behavior. Because of the huge amount of data, the usage of modern machine learning and data-driven approaches is necessary. Although computing big data is not easily handled especially onboard a vehicle, the critical mass of the diverse data generated from different sources is essential. In the field of autonomous vehicles, there have not been standards yet, but the range of applied sensors is well-known. Most systems use a combination of cameras, radar, and LIDAR (Light Detection and Ranging) sensors that transmit data to a central computer that detects the environment around the car. Self-driving development could be supported with model-sized self-driving vehicles because of the complexity of the area. The development of autonomous vehicles consists of security, communication, and data processing issues. Mistakes are increasing the risks of potential accidents. The realistic environment which can be simulated or built makes it possible that the learned behavior can be carried across the platforms while the differences in the sizes are not playing an important role in the matter of learning. The previous reason causes the model-size self-driving development to be more cost-effective. In our work, we developed a self-driving model car with different types of sensors. Measurement data from them can be used to improve the self-driving capabilities of the vehicle.","PeriodicalId":271992,"journal":{"name":"2022 IEEE 2nd Conference on Information Technology and Data Science (CITDS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131280884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The related industry is one of the most expensive areas nowadays. The core of these complex controlling systems is the perception of the environment and the usage of actuators for changing supported by sensors to give obvious feedback about the change of state. Steering controlling is such a subsystem. In the real-sized modern car, there are several methods for implementing feedback loops for it, such as torque and angle sensors. In this paper, we concentrate on extending our model-based research and development autonomous vehicle platform – DAVE to be able to study the hard conditions safely and cost-effectively. This work presents a method for a new sensor signal integrated into our CAN-BUS system to give feedback about the steering movement of the wheels to a digital steering controller using a rear-view camera. The advantage of using a rear-view blind-spot camera is that it is already in place, and no additional hardware is needed to use it as a pseudo angle sensor.","PeriodicalId":271992,"journal":{"name":"2022 IEEE 2nd Conference on Information Technology and Data Science (CITDS)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114241275","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Various tasks from low-level robot control to signal and data processing can be offloaded to network devices. In the past years, solutions exploiting programmable switching ASIC, FPGA or the combination of both have emerged. In this paper, we propose a GPU-accelerated switch design for supporting payload processing tasks in the network. The proposed design combines the processing capabilities of GPUs and the kernel-bypass library DPDK. We define different image processing use cases that can benefit from in-network computing, allowing execution without the need for an external server. The proposed method cannot only make the overall system performance better, but also reduce the power consumption since it requires less hardware elements. We evaluate and compare three models: Traditional external server with GPU in the local network, DPDK accelerated version of the previous model and the proposed GPU-accelerated in-network computing switch model. We investigate several benchmarks including both component-level and system-wide analysis. The examined use cases are related to video stream processing tasks like box blurring, Gaussian blurring and edge detection, demonstrating the performance improvement of our proposed design.","PeriodicalId":271992,"journal":{"name":"2022 IEEE 2nd Conference on Information Technology and Data Science (CITDS)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124587919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
