We study the possibility of using convolutional neural networks for wavefront sensing from a guide star image in astronomical telescopes. We generated a large number of artificial atmospheric wavefront screens and determined associated best-fit Zernike polynomials. We also generated in-focus and out-of-focus point-spread functions. We trained the well-known “Inception” network using the artificial

Turbulent exchange coefficients are studied by field experiments and by mathematical models. The field experiments give a horizontal diffusivity of about 200 em'/s- The vertical exchange coefficient departs on the wind and is about 10 em'/s. Il has a maximum value a few metres below the surface and lends to fall to molecular values in the thermocline. Only where the thermocline is in contact with

Circuit complexity has been used as a tool to study various properties in condensed matter systems, in particular as a way to probe the phase diagram. However, compared with measures based on entanglement, complexity has been found lacking. We show that when imposing penalty factors punishing nonlocality, it becomes a much stronger probe of the phase diagram, able to probe more subtle features. We

The WT1 protein, a product of the Wilms’ tumour 1 gene (WT1) is a zinc finger transcription factor implicated in a number of cellular processes particularly involved in the development of the urogenital system. Mutations in this gene have been implicated in abnormal development of the urogenital system resulting in syndromes such as the Denys-Drash, WAGR and Frasier and in the childhood kidney mal

A 0.18 mum 1.8 V CMOS transmitter for 10/100Mbps Ethernet physical layer standards is described in this paper. The circuit is substantively a current-steering digital-to-analog converter with 5-bit resolution, 125MHz sample rate and 4ns transition time. A novel latch circuit is designed, as well as a structure is provided to realize the accurate rise/fall time control of waveform

A frequency synthesizer applied to 10/100 Base-T Ethernet transceiver is described. It can work in 10Mbps or 100Mbps mode adaptively and convert from one mode to another freely. The circuit can meet both requirements of transmitter on rising/falling time and receiver on CDR so that the additional power and area are saved. Under some testing circumstance, G of voltage control oscillator jittercycle

Today there are climate policy targets within the EU and Sweden about limiting global warming and drastically reducing greenhouse gas emissions. In order to stay within the goal of a global warming of less than 2 ºC, the industrialised countries should decrease their emissions by 80-95 % in 2050, and bring them down to zero in the longer run. Scenario studies indicate that this is possible to achi

Public transport plays a major role in sustainable development of urban areas. However, transportation and infrastructure have to be efficient and in line with the wishes and demand of passengers. Local people have knowledge and experiences of the quality of services they want. When locals are involved, they include grass-root knowledge about ecology, environment, local livelihood problems and res
