This article presents our work toward correct and efficient automatic differentiation of OpenMP parallel worksharing loops in forward reverse mode. Automatic is a method to obtain gradients numerical programs, which are crucial optimization, uncertainty quantification, machine learning. The computational cost compute common bottleneck practice. For applications that parallelized for multicore C...

We address the “freeform optics” inverse problem of designing a reflector surface mapping prescribed source distribution light to far-field distribution, for finite source. When reduces point source, has support only on optics ray directions. In this setting, is well-posed arbitrary and target probability distributions. It can be recast as an Optimal Transportation been studied both mathematica...

This paper proposes a novel topology of multilevel current source inverter which is suitable to apply in low/medium voltage. The proposed topology is capable of producing desirable bidirectional output current levels. Furthermore, it can employ symmetrical DC current sources as well as asymmetrical ones which is a significant advantage. Asymmetrical mode makes it possible to generate a great nu...

This paper presents a design of an UWB downconversion integrated CMOS resistive ring mixer with Linear Voltage Regulator (LVR), to supply required biasing voltages for the mixer section. The designed mixer circuit has been optimized for using in heart rate extraction system with microwave Doppler radar at 2.4GHz frequency. This mixer needs 2 DC bias voltages equal to 0.5 and 1 volts for its bes...

electronic health record (ehr) is a repository of patient health information shared among multiple authorized users. as a modern method of storing and processing health information, it is a solution for improving quality, safety and efficiency of patient care and health system. however, establishment of ehr requires a significant investment of time and money. while many of healthcare providers ...
