The lighting control system by paying attention to the number of lights activated/turning on in building hall is very important because must have good for various activities/events hall, especially nature which tends a large capacity and closed so that arrangements become matter be considered. method this study AC_light_dimmer technique timing system. designed has been integrated with Internet ...

The eye can adapt to the rate of change of brightness. After exposure of the eye to a light that grows gradually brighter, a steady light appears to grow gradually dimmer, and vice versa. A field containing shading gives larger after effects than a spatially uniform field.

The relationship between the slow potential and spikes of second-order ocellar neurons of the cockroach, Periplaneta americana, was studied. The stimulus was a sinusoidally modulated light with various mean illuminances. A solitary spike was generated at the depolarizing phase of the modulation response. Analysis of the relationship between the amplitude/frequency of voltage modulation and the ...

The brain's ability to ignore repeating, often redundant, information while enhancing novel information processing is paramount to survival. When stimuli are repeatedly presented, the response of visually sensitive neurons decreases in magnitude, that is, neurons adapt or habituate, although the mechanism is not yet known. We monitored the activity of visual neurons in the superior colliculus (...

Lack of energy proportionality in server systems results in significant waste of energy when operating at low utilization, a common scenario in today’s data centers. However, even during times of low utilization, servers cannot be powered off because of unpredictable spikes in instantaneous demand on some of the resources (e.g., file storage). To mitigate energy waste, unused processor cores tr...

Very rarely have two eye diseases been so widely confused as nummular keratitis (Dimmer) and epidemic keratoconjunctivitis. Confusion in the literature has there­ fore occurred and this has made studies on etiology more difficult. The mistaking of these two diseases is surprising in view of Dimmer's excellent description of his cases in 1905, and in view of Salzmann's presen­ tation of more tha...

Negara dengan tingkat kepadatan tinggi pasti membutuhkan tempat tinggal yang banyak. Hidroponik memakai media bukan tanah adalah salah satu solusinya. di dalam ruangan memerlukan pengganti cahaya matahari. Oleh karena itu, penelitian ini mengembangkan sistem untuk mengontrol intensitas tanaman hidroponik metode inovatif. Alat menyesuaikan kondisi dan daya keluaran sesuai lampu melalui proses fu...
