The expense of composing test code may be equivalent to or higher than the expense of composing creation code. Robotized unit test generators are every now and again utilized by designers to speed up programming testing. These instruments are intended to accelerate creation without compromising code quality. In any case, as unit tests normally miss the mark on quality control layer over the testing code, it could be trying to guarantee the honesty of the tests that are made. One way to ensure the quality of the tests is to break down the presence of test smells in the test code. Test code highlights known as 'test smells' may highlight imperfections in test origination and execution. Their reality could act as a measure of value. In this review, we utilized a multi-stage, cross-approved manual examination to order and name six different test fragrance types. We look at the viability of two test fragrance discovery frameworks, one that has been around for some time and one that was simply delivered with the express motivation behind copying engineer view of test smells. More specifically, the more established methods for identifying the devices incorrectly classified more than 70% of test smells, not only leaving out actual cases (false negatives) but also labeling many tests without smell as foul (misleading positives). According to our findings, these test smell recognition techniques performed a subpar job of describing the issues in naturally generated test suites). © 2024 IEEE.

Secure Beamforming and Power Allocation for RIS-Assisted NOMA-ISAC Systems With Internal and External Eavesdroppers

IEEE Transactions on Cognitive Communications and Networking 2025年

作者： Li, Yaming Jin, Ming Guo, Qinghua Yao, Junteng Jiang, Tao Liu, Juan Ningbo University Faculty of Electrical Engineering and Computer Science Ningbo315211 China University of Wollongong School of Electrical Computer and Telecommunications Engineering WollongongNSW2522 Australia

This work investigates secure transmission in non-orthogonal multiple access (NOMA)-integrated sensing and communication (ISAC) systems, where legitimate users may act as internal eavesdroppers alongside external eavesdroppers. We propose a reconfigurable intelligent surface (RIS)-assisted channel selection scheme to degrade channels of internal eavesdroppers and enhance legitimate links. To counter external eavesdroppers, we minimize communication power while satisfying constraints on communication rates, security and sensing performance. Then, we formulate a secure beamforming and power allocation optimization problem, and then propose a semidefinite relaxation (SDR) and penalty-based alternating optimization (AO) algorithm to solve it. The convergence and the computational complexity of the proposed algorithm are analyzed and numerical results are provided to demonstrate the superior secure performance of the proposed scheme. © 2015 IEEE.

We demonstrate a unidirectional ring hybrid diode laser based on integration of a hook-shaped traveling-wave semiconductor optical amplifier (SOA) and Taiji ring resonator. The additional crossover bending waveguide inside the silicon nitride Taiji ring introduces a nonreciprocal loss in the laser cavity while the gain is provided by a multiple depth etched hook-shaped SOA. © 2023 The Author(s)

The effect of substrate properties on the tuning range of frequency-reconfigurable antennas is investigated in this paper. To this end, the behavior of a representative antenna geometry is analyzed for substrates with various relative permittivities and thicknesses. Based on the simulation results, a well-defined relationship between the tuning range and the substrate material characteristics is observed. It can be concluded that, for a given antenna structure, defined by the antenna topology and the number of lumped components, an optimized antenna realized on a thicker and lower-permittivity substrate will provide a larger tuning range, with a tuning range variation being well above a factor of two for the considered substrate variations. © 2024 IEEE.

A new configuration is proposed for filters with parallel coupling paths between the source and load in this paper. The proposed fourth-order waveguide bandpass filter (BPF) with two parallel coupled paths is formally designed through this structure. The filter is working at 6.5 GHz and with 300 MHz bandwidth. Due to the two parallel coupling paths, a pair of transmission zeros (TZs) are generated out of passband. Compared with previous waveguide filters, the coupling paths are connected to the source and load in different sides of input/output waveguide. In this way, the waveguide cavity of the resonator can be increased and the insertion loss of the filter can be greatly reduced. The effectiveness of the fourth-order waveguide bandpass filter is verified by simulation results. © 2023 IEEE.

The approach of (fixed-) time-synchronized control (FTSC) aims at attaining the outcome where all the system state-variables converge to the origin simultaneously/synchronously. This type of outcome can be the highly essential performance desired in various real-world high-precision control applications. Toward this objective, this article proposes and investigates the development of a time-synchronized reinforcement learning algorithm (TSRL) applicable to a particular class of first- and second-order affine nonlinear systems. The approach developed here appropriately incorporates the norm-normalized sign function into the optimal system control design, leveraging on the special properties of this norm-normalized sign function in attaining time-synchronized stability and control. Concurrently, the actor–critic framework in reinforcement learning (RL) is invoked, and the dual quantities of system control and gradient term of the cost function are decomposed with appropriate time-synchronized control items and unknown actor/critic part and to be learned independently. By additionally employing the adaptive dynamic programming technique, the solution of the Hamilton–Jacobi–Bellman equation is iteratively approximated under this actor–critic framework. As an outcome, the proposed TSRL method optimizes the system control while attaining the notable time-synchronized convergence property. The performance and effectiveness of the proposed method are demonstrated to be effectively applicable via detailed numerical studies and on an autonomous vehicle nonlinear system motion control problem. © 2020 IEEE.

In general, public or private organizations or companies have used information-based technology as a support to improve business performance to be more effective and efficient in order to achieve a company's business goals. Given the large contribution of information technology in the application of hotel applications as a supporting information system, it is a vital system that must avoid risks that can hinder and cause harm to the hotel management business processes. Therefore, it is necessary to carry out risk management using the COBIT 5 framework to manage possible risks that may occur based on the APO12 (Manage Risk) domain. From the evaluation results of the data obtained through observation and interviews as well as the calculation of the results of the questionnaire based on 6 APO12 subdomains, the results of the risk management level capability assessment in hotel applications are still at level 3 or have reached the level of established process with the target to be achieved at level 4 resulting in a gap of 1 level. Based on the results obtained, it is necessary to propose recommendations that can be used by hotels in improving the application of information technology risk management so that in the future it can achieve the expected target level so that the APO12 level of capability can increase and become more optimal. © 2023 IEEE.
