This paper presents an innovative single-stage grid-integrated solar photovoltaic (PV) system for water-pumping applications using an induction motor drive (IMD). The proposed system employs a seven-level diode-clamped multilevel inverter (MLI) to convert DC power from the PV array to AC power for the motor, eliminating the need for an intermediate DC-DC converter. A perturb and observe (P&O) algorithm is utilized for the PV array’s maximum power point tracking (MPPT). Direct torque control (DTC) with space vector modulation (SVM) provides precise speed regulation of the induction motor. The system enables bidirectional power flow between the PV array, motor load, and utility grid, optimizing energy utilization under varying irradiance and demand conditions. The proposed configuration exhibits enhanced efficiency and improved power quality compared to conventional two-stage topologies, offering a promising solution for grid-connected solar-powered water pumping systems.
Identifying Silent Mutations for the Introduction of Restriction Sites in Open Reading Frames
For many applications in molecular biology, restriction sites need to be engineered into an open reading frame (ORF), a part of the genetic material that codes for a protein. Importantly, silent mutations need to be performed because only these do not alter the amino acid sequence of the protein. However, finding such silent mutations is a very time-consuming process. We have developed a program which recognizes all silent mutations in an open reading frame (ORF) that each lead to a new restriction site. Our program uses python technologies comprising web crawlers and data analysis libraries to deduce the amino acid sequence coded by an ORF and convert the ORF nucleotide sequence into the amino acid single letter sequence. In doing so, reverse translation back into the nucleotide sequence allows the consideration of all possible nucleotide sequences coding for the same amino acid sequence, which are then compared with the restriction recognition sites of commercially available restriction enzymes, such as from New England Biolabs (e.g., https://www.neb.com/). This allows the identification of restriction sites that can be engineered via silent mutations within the provided DNA input sequences. The output is presented in a user-friendly tabular format that can be examined or downloaded (as a CSV file) for ongoing evaluations.

North Atlantic Offshore Wind Characteristics: Modeling and Comparison with Field Measurements and Industry Standards
Wind characteristics are critical to offshore wind resource development. The power output from a wind turbine is very sensitive to the local wind speed. Wind speed measurement is often limited to surface area close to Lidar buoys or meteorological stations and up to 200m due to the range of remote sensing devices. On the other hand, wind fields from ground level and up to 20000m above ground level can be simulated using Weather Research & Forecasting (WRF) model. In this study, WRF simulations are performed for the North Atlantic offshore waters to obtain wind speed time and spatial properties. Statistics of wind speeds for selected sites are derived and validated with field measurements. Wind vertical profiles are compared with ISO and IEC standards, and a power law profile is further derived to find the best fit. It is also demonstrated that the WRF model is reliable to forecast wind data, optimize prediction and improve reliability for coastal and offshore energy development. The wind modeling and characterizing can be extended to global regions to identify prospects with the most renewable energy potentials.

Robust Cascade PID-based Controller Design for Brushless DC Motor using Antlion Optimization Algorithm
Brushless DC (BLDC) motors are widely utilized in various fields, including high-speed drives, artificial heart pumps, and electric vehicles, due to their superior torque, compact size, and enhanced efficiency. However, it is very difficult to obtain satisfactory control
performance for BLDC motors using conventional PID
controller, because of the difficulty in tuning the proper PID parameters.
In this paper, an optimal cascade PID controller is designed for
controlling the BLDC motor. The proposed cascade controller consist of an inner loop and an outer loop, each responsible for different aspects of the control process. The inner loop handles fast dynamics, namely current control, while the outer loop deals with slower dynamics, as speed control. This separation allows each loop to be optimized individually, resulting in improved overall system performance and stability. By quickly responding to disturbances in the inner loop, cascade controllers can effectively overcome oscillations and enhance the stability of the motor. Additionally, cascade controllers can better handle non-linearities and parameter variations, leading to more accurate and reliable control of the output. However, tuning PID controller gains is crucial for achieving optimal performance and stability in control systems, and metaheuristic algorithms offer significant benefits by efficiently searching for the best gain values, even in complex and high-dimensional parameter spaces. The proposed cascade PID controller’s gains are optimized using the Antlion Optimization (ALO) algorithm, a modern metaheuristic algorithm known for its effectiveness in constrained problems and diverse search spaces. This optimization enhances the controller’s robustness against disturbances, particularly supply voltage variations. To validate the system’s performance, Hardware-in-Loop (HIL) Typhon technology is employed, allowing real-time testing of the BDCM and controller under various conditions. This ensures the reliability and effectiveness of the system before actual implementation.
