چکیده
Used in a wide range of industrial, automotive, and commercial applications, electric motors are controlled by drives that vary the electrical input power to control the torque, speed, and position. High-performance motor drives can increase efficiency and deliver faster, more accurate control. Advanced motor-control systems combine control algorithms, industrial networks, and user interfaces, so they require additional processing power to execute all tasks in real time. Multichip architectures are typically used to implement modern motor-control systems: a digital signal processor (DSP) executes motor-control algorithms, an FPGA implements high-speed I/O and networking protocols, and a microprocessor handles executive control.1

Time interleaving is a technique that allows the use of multiple identical analog-to-digital converters1 (ADCs) to process regular sample data series at a faster rate than the operating sample rate of each individual data converter. In very simple terms, time interleaving (IL) consists of time multiplexing a parallel array of M identical ADCs, as shown in Figure 1, to achieve a higher net sampl...

متن کاملEnhanced killing of breast cancer cells by a d-amino acid analog of the winter flounder-derived pleurocidin NRC-03.
Cationic antimicrobial peptides (CAPs) defend against pathogens and, in some cases, exhibit potent anticancer activities. We previously reported that the pleurocidin NRC-03 causes lysis of breast cancer and multiple myeloma cells. NRC-03 also reduces the EC50 of other cytotoxic compounds and prevents tumor growth in vivo. However, the therapeutic utility of NRC-03 may be limited by its suscepti...
