Characterization of wind turbine flow through nacelle-mounted lidars: a review

Fernando Porté Agel, Peter Andreas Brugger

This article provides a comprehensive review of the most recent advances in the planning, execution, and analysis of inflow and wake measurements from nacelle-mounted wind Doppler lidars. Lidars installed on top of wind turbines provide a holistic view of ...

A wind tunnel study on cyclic yaw control: Power performance and wake characteristics

Fernando Porté Agel, Arslan Salim Dar, Guiyue Duan

In this study, wind-tunnel experiments are used to investigate cyclic yaw control as a wake mitigation strategy aiming to improve wind farm power production. The control strategy is applied to a single wind turbine and a wind farm comprising of a column of ...

Evidence that the Lunar Cycle Influences Human Sleep

Endogenous rhythms of circalunar periodicity (similar to 29.5 days) and their underlying molecular and genetic basis have been demonstrated in a number of marine species [1, 2]. In contrast, there is a great deal of folklore but no consistent association o ...

Circadian rhythms in insect disease vectors

Antonio Carlos Alves Meireles Filho

Organisms from bacteria to humans have evolved under predictable daily environmental cycles owing to the Earth's rotation. This strong selection pressure has generated endogenous circadian clocks that regulate many aspects of behaviour, physiology and meta ...

The Suitability of Radiance for Calculating Circadian Potential

Sharon Jane Gochenour

This research project deals with the suitability of the program Radiance for detailing the spectral qualities of the light received inside a room. More specifically, it asks whether Radiance’s innate RGB algorithm can be used to accurately determine the no ...

SleepPic. Hardware Developments for a Wearable On-line Sleep and Wake Discrimination System

Dario Floreano, Walter Karlen

The design of wearable systems comes with constraints in computational and power resources. We describe the development of customized hardware for the wearable discrimination of human sleep and wake based on cardio-respiratory signals. The device was desig ...

Sex difference in the near-24-hour intrinsic period of the human circadian timing system

Mirjam Münch

The circadian rhythms of melatonin and body temperature are set to an earlier hour in women than in men, even when the women and men maintain nearly identical and consistent bedtimes and wake times. Moreover, women tend to wake up earlier than men and exhi ...

Model for view direction as a function of light distribution

Mandana Sarey Khanie

Discomfort Glare: - Focus on understanding discomfort glare - Embedding eye‐movement patterns in glare assessments - Refining glare position index. Problem: - The light of sight in glare position index is assumed to be fixed - In a natural experience, line ...

Effects on subjective and objective alertness and sleep in response to evening light exposure in older subjects

Mirjam Münch

Evening bright light exposure is reported to ameliorate daytime sleepiness and age-related sleep complaints, and also delays the timing of circadian rhythms. We tested whether evening light exposure given to older adults with sleep–wake complaints would de ...

Adaptive Sleep-Wake Discrimination for Wearable Devices

Dario Floreano, Walter Karlen

Sleep/wake classification systems that rely on phys- iological signals suffer from inter-subject differences that make accurate classification with a single, subject-independent model difficult. To overcome the limitations of inter-subject variability we s ...
