Active and Passive Transport at Interfaces
… In each of them one physical aspect of active and passive transport is discussed. The four systems are arranged and discussed in four separate chapters. In chapter 3 and 4 we study the effect of static or hydrodynamic interactions on the cross over from individual diffusion towards …

Optimization methods for active and passive localization
Active and passive localization employing widely distributed sensors is a problem of interest in various fields. In active localization, such as in MIMO radar, transmitters emit signals that are reflected by the targets and collected by the receive sensors, whereas, in passive localization the …

Active and Passive Settling By Marine Benthic Nematodes
<p>This study investigates whether active processes participate in the settlement of marine benthic nematodes. The settling rates of three estuarine benthic nematode taxa were examined in a linear flume using two treatments defined by the type of sediment bed placed in the flume. One treatment bed …

Carbohydrate metabolism during active and passive post-exercise recovery
… period, increases the rate at which lactate and protons are removed from the circulation. This study examined the effect which this light activity had on muscle glycogen and lactate levels, as well as the restoration of blood fuel and hormonal homeostasis. A further dimension of the study was …

Laser micromachining of active and passive photonic integrated circuits
… the development of advanced laser resonators and applications of laser-induced micromachining for photonic circuit fabrication. Two major advantages of laser-induced micromachining are direct patterning and writing on large areas of substrates at high speed following the exposure of laser …

Element and system design for active and passive vibration isolation
This thesis focusses on broadband vibration isolation, with an emphasis on control of absolute payload motion for ultra-precision instruments such as the MIT/Caltech Laser-Interferometric Gravitational Wave Observatory (LIGO), which is designed to measure spatial strains on the order of 10-²¹. We …

Optimal self assembly of modular manipulators with active and passive modules
… build self-assembling robot systems composed of active modular robots and passive bars. The robotic module is the Shady3D robot and the passive component is a rigid bar with embedded IR LEDs. We propose algorithms that demonstrate the cooperative aggregation of modular robotic manipulators with …

Dynamics of Multi-Agent Systems with Bio-Inspired Active and Passive Sensing
Active sensors, such as radar, lidar and sonar, emit a signal into the environment and gather information from its reflection. In contrast, passive sensors such as cameras and microphones rely on the signals emitted from the environment. In the current application of active sensors in multi-agent …

Role of active and passive recovery in adaptations to high intensity training
… separated by 4-min recovery) was examined and active recovery (cycling at 20 to 40% of V̇O2peak) has been shown to improve sprint performance with successive sprints by 6 to 12% compared to passive recovery (remained still), while increasing aerobic contribution to sprint performance by …

Applications of global equity style indices in active and passive portfolio management
The success of the Fama and French 3-factor model in explaining empirical anomalies of the Capital Asset Pricing Model (CAPM) suggests that style investing which places portfolios out-of-sync with the broad market has the potential to generate significant alpha. Since momentum abnormal return is …

Active and passive assets, their returns and the role of market efficiency
Passive investments, as a vehicle of fund allocation, have grown to comprise an increasingly significant portion of the global investment landscape, substantially due to the relative underperformance of active investments. Several prior studies have noted the existence of a relationship between the …
