What is the main algorithm used in this paper?5 answersThe main algorithm used in the papers is as follows: The algorithm inis a numerical algorithm based on the RCW method to solve a set of first-order ordinary differential equations. It uses a polynomial of degree 2 to represent the answer of each equation, with coefficients categorized into free and fixed coefficients. The free coefficients are optimized using an error function, while the fixed coefficients are computed from the derivative of the polynomial at the initial value. This algorithm shows higher accuracy and stability compared to the Runge-Kutta method. The algorithm inis an equivalent source algorithm for calculating the electromagnetic parameters of triangular periodic microstrip array antennas. It determines the active element pattern of the smallest element in the array and reconstructs the array antenna using the equivalent source method. By reducing the antenna size and calculating the simplified array pattern, the algorithm derives the required microstrip array antenna pattern. The algorithm inis a simple algorithm for implementing second-order-polynomial-based peak-tracking methods in FBG sensors. It decomposes the Moore-Penrose coefficient matrix into an upper triangular matrix and a symmetric matrix, allowing for a simplified equation to determine peak wavelength. This algorithm does not involve matrix multiplication and inverse matrix solution, making it efficient and suitable for real-time applications. The algorithm inis a stochastic algorithm for studying the dynamics of chain-like bodies. It models chain movements by sequentially shifting and rearranging segments based on a problem-specific probability distribution. This algorithm achieves a considerable gain in memory allocation and has been validated by comparing passage times for polymer translocation through a pore. The algorithm inis used for detecting objects in a coherent reception of signals from a monitoring network. It uses statistics that consider the stable features of the data distribution to provide a constant probability of false alarm at any noise level. This algorithm can be implemented in an automated decision support system for environmental pollution detection, improving the reliability of detection decisions.

What are black box attacks in beamforming?4 answersBlack box attacks in beamforming refer to adversarial example generation attacks against machine learning models deployed in future 5G networks for intelligent beamforming. These attacks aim to manipulate the inputs to the machine learning models during the inference stage over the air, causing the models to return incorrect outputs. This compromises the integrity of the target model and negatively affects the functionality of the network framework under attack. The construction of black box adversarial images in these attacks is a challenging problem, as it requires efficient attacks within a limited query budget. However, a simple and highly query-efficient algorithm has been proposed, which randomly samples a vector from a predefined orthonormal basis and adds or subtracts it to the target image. This algorithm demonstrates unprecedented query efficiency and can be used for both untargeted and targeted attacks.
What is blackbox testing?5 answersBlackbox testing is a technique used to test applications without knowing their internal workings. It focuses on testing the functionality and features of the application. Testers create test cases by selecting input information to find errors and ensure that the program functions as expected. The Equivalence Partition method is commonly used in blackbox testing to divide input values into groups and select test cases from each group. This method helps identify potential errors and improve the quality of the application. Blackbox testing is important in application development to ensure that the program runs properly and to identify any errors or areas for improvement.
