programming anxiety encompasses negative emotions, including uneasiness, panic, fear, and nervousness experienced by students while learning a computer programming language. Evidence indicates that programming anxiety impedes students' programming ability and performance. Nine non-computer science students undertaking Python programming course were selected for semi-structured interviews based on the outcomes of programming Anxiety Scale. Based on interview findings, it was discovered that students' self-efficacy, features of programming courses, teaching beliefs of instructors, support platforms, and programming-related subjects may cause programming anxiety. To mitigate this, various instructional strategies were suggested to increase programming skills and alleviate the adverse impact of programming anxiety.

Traditional stability controllers are constructed based on the equilibrium points of power systems and fail to meet the performance criteria under large disturbances. In this paper, an algorithm has been proposed to design transient stability controllers for power system using Sum-of-squares (SOS) programming which is a powerful technique able to answer many analysis questions for nonlinear systems. Since the SOS programming only deals with polynomial systems, first we recast the power system model into polynomial form. then we derive the algorithm from the Lyapunov theory to search for stability controllers of power systems, by introducing the so-called target region and expanding the estimated stability region. the effectiveness of our algorithm is demonstrated on the IEEE 3-machine-9-bus power system.

this paper discusses Lyapunov stability verification methods for continuous-time nonlinear systems. Traditional mathematical methods require a lot of manual calculations, which consume a lot of time and energy. To address the problem of the low efficiency in traditional methods, this paper introduces neural networks into the design of the Lyapunov function to achieve independent verification. First, a neural network is used to represent the Lyapunov function. then, the Lyapunov stability condition is converted into a mixed integer linear programming (MILP) problem, and the solution to the optimization problem is solved through the MILP solver to verify whether the output of the neural network satisfies the Lyapunov stability condition. In addition, this paper gives the training loss function of the Lyapunov neural network, which mainly consists of optimization problems. Finally, a simulation example is given to illustrate the effectiveness of this method.

Following the COVID-19 pandemic, Sri Lanka's economy faced significant setbacks, particularly in key sectors such as tea exports, garment manufacturing, and tourism, which experienced severe downturns. However, the IT sector showed resilience amid these challenges, highlighting its potential to drive economic growth. Despite this potential, Sri Lanka has struggled to capitalize fully on global demand for IT services due to a skills gap among Sri Lankan youth compared to their Indian counterparts. India's IT outsourcing industry has thrived partly because of the early involvement of young professionals in open-source projects such as the Android Open Source Project (AOSP), Linux Kernel and React. this trend underscores the importance of foundational programming education to develop competitive technical skills from a young age. To address this gap, authors developed a mobile learning solution CodeSafari, designed to introduce core programming concepts data types, conditional statements, and loops to young Sri Lankan learners. the platform uses Personalized Storytelling and a Customized Kids Assisting System in students' native language, making programming more accessible. programming training withthe app improved test scores for 58 percent of participants. By addressing the skills gap early, this research aims to build a strong IT foundation for Sri Lankan students, positioning them to compete more effectively in the global outsourcing market. these findings underscore the essential role of programming education in fostering economic resilience and preparing a workforce capable of thriving in an evolving technology landscape.

Transient stability analysis (TSA) of large-scale power systems is one of the most computationally significant tasks. To reduce the difficulty of this task, this paper uses a coherency-based dynamic equivalent method to obtain the aggregation model of multi-machine systems, which is a valid approach to reducing the size of power system model. Based on this aggregation model, the expanding annular domain (EAD) algorithm based on sum of squares (SOS) programming is employed to estimate the domain of attraction (DA) of the aggregation model, which provides an approximate description of transient stability of the original system model. the validity of our proposed methodology is illustrated on a 15-machine 73-bus system. Simulation results show that the proposed method can provide better estimates in terms of DA and critical clearing time (CCT) for large-scale power systems.
this study investigates the differences in energy consumption between various programming languages, comparing those executed natively withthose run on a Virtual Machine. the results challenge existing assumptions ab...

High complexity is one of harsh problems in transient voltage stability analysis (TVSA) of power systems. To overcome this difficulty, a state-reduction model incorporating induction motors (IMs) has been considered. And an expanding interior algorithm based on Sum of Squares (SOS) programming is adopted to estimate the domain of attraction (DA) of the state-reduction model for TVSA. First the state space is transformed to polynomial space using coordinate transformation. then based on Lyapunov stability theorems, relaxed constraints for the DA are derived. then the expanding interior algorithm based on SOS programming is utilized to simultaneously optimize the Lyapunov function and the DA. the proposed methodology is validated through modified IEEE test cases, demonstrating its effectiveness and robustness in enhancing transient voltage stability assessment in complex power systems.
