Heterogeneous multi-core systems that contain multiple CPUs and GPUs are gaining momentum, as they are providing different computation power to meet the performance demand of modern applications. On such systems, developers try to fully utilize the computation power both for CPU and GPU by using the emerging programming models such as CUDA and OpenCL. To achieve the maximal performance, developers...
Smartphones have become common tools in people's daily life. Lots of popular applications (e.g., social network applications) have immigrated from traditional computers to smartphones. With the growth of the apps, attacks on these apps are also increasing. One serious attack adds malicious payloads or advertisements to legitimate apps. These modified apps, called repackaged apps, share similar functionalities...
This paper presents a transmitter and receiver phased array chipset fabricated in a 0.18µm SiGe BiCMOS process with ƒT / ƒMAX of 240/270GHz. Each chip comprises four phased array elements with distributed calibration memory and calibrated direct up and down-conversion mixer chain. Both transmitter and receiver arrays operate from 1.5V and 2.5V power supplies and consume 1W each. Each receive channel...
An analytical model is proposed to calculate the initial infusion of a microneedle array driven by a micropump. By assuming the initial infusion of each microneedle undergoes a spherical expansion, the model is able to calculate the time-varying expansion radius, as well as the flow rate and infusion pressure, provided that the material properties and the microneedle system parameters are known. For...
This paper presents prediction maximum power point tracking (PMPPT) controller for PV-battery micro-satellite systems with body mounted Solar Panels. The proposed PMPPT method includes conventional perturbation and observation (P&O) MPPT method and grey prediction method to improve the efficacy of PV system with auto-tuning the perturbation step. This paper uses the Taiwan Universities United...
