This study compared the physiological, perceptual and mechanical responses to kettlebell swings at different loads and swing speeds. Following familiarization 16 strength trained participants (10 males, six females, mean age ± SD = 23 ± 2.9) performed four trials: 2 min kettlebell swings with an 8 kg kettlebell at a fast cadence; 2 min kettlebell swings with an 8 kg kettlebell at a slow cadence...

|In this paper we present a Low Voltage Diierential Current Switch Logic (LVDCSL) gate which is capable of achieving high performance for large fan-in gates. High fan-in is enabled by allowing large stacked NMOS tree heights using a pre-discharged NMOS tree, at the same time the power penalty of an increased number of internal nodes in the gate is mitigated by restricting internal node voltage ...

Current comparator is a fundamental component of current-mode analog integrated circuits. A novel high-performance continuous-time CMOS current comparator is proposed in this paper, which comprises one CMOS complementary amplifier, two resistive-load amplifiers and two CMOS inverters. A MOS resistor is used as the CMOS complementary amplifier’s negative feedback. Because the voltage swings of t...

The lifetime of the solder joint between base plate and ceramic substrate is usually tested by passively heating and cooling the IGBT module (thermal cycling). This provokes failures (delamination) in that solder layer. But, the IGBT and diode dies are actively heated in the application. Other failure modes (e.g. bond wire lift off) are addressed and limit the lifetime. This kind of stress is u...

An image classification technique, which has recently been introduced for visual pattern recognition, is successfully applied for human gait classification based on radar Doppler signatures depicted in the time-frequency domain. The proposed method has three processing stages. The first two stages are designed to extract Doppler features that can effectively characterize humanmotion based on th...

Coaches have identified the batter's weight shift as a critical component for promoting proper timing and balance in a baseball swing. Analysing the weight shift through maximum horizontal (Fx) and vertical (Fz) ground reaction forces (GRFs) of professional batters (N = 29; height = 185 +/- 6 cm; mass = 92 +/- 9 kg), the purpose of this study was to compare GRFs among swings against fastballs a...
