In this paper, we propose a novel method that uses a velocity field map and long short-term memory (LSTM) neural network to control agents to avoid collisions with nearby agents by considering their previous trajectories. Our method uses a series of continuous velocity field maps that represent the surrounding conditions of the controlling agent. A velocity field map comprises 2-channel images containing the positions and velocities of the controlling and nearby agents. We employed an LSTM neural network to predict the current velocity field map from the velocity field maps of the previous frames to determine the desired velocity of the controlling agent. The agent is controlled using a social force method based on the desired velocity. The novelty of our method lies in the use of the velocity field map and LSTM neural network. By using the velocity field map, the information of the controlling agent and its surrounding salutation is efficiently represented. In addition, by using a series of continuous velocity field maps and LSTM, the agent is efficiently controlled considering the previous frames. We present experimental results and discuss the advantages of the proposed approach.

Membrane computing, which is also known as a P system, is a computational model inspired by the activity of living cells. Several P systems, which work in a polynomial number of steps, have been proposed for solving computationally hard problems. However, most of the proposed algorithms use an exponential number of membranes, and reduction of the number of membranes must be considered in order to make a P system a more realistic *** the present paper, we propose an asynchronous P system using branch and bound for solving the minimum Steiner tree. The proposed P system solves the minimum Steiner tree with n vertices and m edges in O(n 2 ) parallel steps or O(2 m n 2 ) sequential *** evaluate the number of membranes used in the proposed P system using experimental simulations. Our experimental results show validity and efficiency of the proposed P system.

Technological developments have resulted in a trend of cryptocurrencies that use a technology called blockchain to create and record all transactions made into a digital ledger. Along with the emergence of the trend of cryptocurrencies, this development has also resulted in crimes that hit the digital world, such as data leakage and cyber espionage. This threat can be prevented by applying blockchain technology to the database that has been used. Therefore, we need a system that can facilitate the use of blockchain technology and can process data from an existing relational database into a blockchain-based database. The system developed in this study was built with the FastAPI framework that uses the Python programming language and the React framework that uses the Javascript programming language. This system was tested using Katalon and Wireshark software to perform throughput testing and man-in-the-middle attacks. Evaluation of this system is assessed based on the average throughput time and also the results of Wireshark packet capture. The system designed in this research is expected to help overcome interoperability problems when using blockchain and improve relational database integrity. The results of the test show that the system is safe from man-in-the-middle attacks while sending data through API and has a faster throughput time than BigchainDB system by 4.151 seconds.

This paper presents a solution for counting fruit in agricultural greenhouses using Unmanned Aerial Vehicles (UAV s). Initially, a heuristic based on Simulated Annealing was used to optimize the UAV's trajectory, ensuring efficient coverage of the beds. Next, digital image processing (DIP) techniques were implemented to count the fruit, including depth segmentation, application of bounding boxes, color filtering, and element counting. The DIP accuracy was evaluated in multiple scenarios and the results indicate high reliability in fruit counting, with the potential to optimize agricultural operations and provide valuable information to producers. Possible future improvements could include further refinements in image processing to increase the accuracy of counting other fruits. Ultimately, this work contributes to the advancement of automation in agriculture by offering a viable and efficient solution for counting fruit in greenhouses using UAV s.
