Colin Clark (1905-89) Economist and Agricultural Economist
No full textIn 1986 the Oxford University Institute of Agricultural Economics was amalgamated into Queen Elizabeth House. The Institute, which came into being in 1913, achieved considerable distinction for its work on the problems of British agriculture under the Directorships of C.S.Orwin and A.W. Ashby. The third Director (1953-69) was of a somewhat different stamp. Colin Clark (1905-89), though without formal training in economics, had established himself as a pioneer of national accounting techniques in the Cambridge of the 1930s (he was mentioned in Keynes' General Theory) and progressed to write one of the classic studies of growth (Conditions of Economic Progress). His name appeared prominently in the Meier and Seers book on 'Pioneers of Development' and there have been many other testaments to his international reputation. The Oxford period witnessed famous controversies on population and food supply, the publication (with Margaret Haswell) of 'The Economics of Subsistence Agriculture', and much other work on a wide range of subjects by no means confined to agricultural issues. The essay which is reprinted below originally appeared in the Italian journal Rivista di Economia Agraria (June 1995) as part of a series on major figures in agricultural economics, and was presented at an Agricultural Economics Society conference (Edinburgh, 1998). It is also the basis for a shorter entry in the Dictionary of National Biography, 1981-90 Supplement. The writer spent a considerable part of his early career as one of Colin Clark's research assistants. A number of people have been kind enough to suggest that the essay should have greater accessibility.

Orbital dynamics of high area-to-mass ratio spacecraft with J2 and solar radiation pressure for novel Earth observation and communication services
No full textThis paper investigates the effect of planetary oblateness and solar radiation pressure on the orbits of high area-to-mass spacecraft. A planar Hamiltonian model shows the existence of equilibrium orbits with the orbit apogee pointing towards or away from the Sun. These solutions are numerically continued to non-zero inclinations and considering the obliquity of the ecliptic plane relative to the equator. Quasi-frozen orbits are identified in eccentricity, inclination and the angle between the Sun-line and the orbit perigee. The long-term evolution of these orbits is then verified through numerical integration. A set of ‘heliotropic’ orbits with apogee pointing in the direction of the Sun is proposed for enhancing imaging and telecommunication on the day side of the Earth. The effects of J2 and solar radiation pressure are exploited to obtain a passive rotation of the apsides line following the Sun; moreover the effect of solar radiation pressure enables such orbits at higher eccentricities with respect to the J2 only case

Modell zur Vorhersage von Prozessparametern eines Laserprozesses auf Basis von RGB-Farbwerten
No full textKünstliches neuronales Netz mit zwei verdeckten Schichten mit 50 bzw. 25 Neuronen und einer ReLU-Aktivierungsfunktion. Die Ausgabeschicht hat eine sigmoide Aktivierungsfunktion. Für das Training wird ein Adam-Optimierer verwendet, der den mittleren quadratischen Fehler der Vorhersage gegenüber der erwarteten Ausgabe minimiert und so die Gewichte des Netzes bestimmt.
Eingänge zw. 0 und 1:
b: Blau im RGB-Farbraum
g: Grün im RGB-Farbraum
r: Blau im RGB-Farbraum
Ausgänge zw. 0 und 1:
hatch_um: Der Hatch-Abstand zwischen Scanlinien in µm
power_mw: Die Laserleistung in mW
pulse_us: Die Pulsrate in µs
speed_um_s: Die Scangeschwindigkeit in µm/s
Skaliert wie folgt:
r, b, g: von 0 bis 255 [-]
hatch_um: von 1 bis 100 in [µs]
power_mw: von 1000 bis 20000 in [mW]
pulse_us: von 2 bis 10 in [µs]
speed_um_s: von 41666 bis 3333333 in [µm/s]
Das Modell kann mit dem folgenden Python-Code ausgeführt werden:
from keras.models import load_model
def scale_value(x, new_min, new_max):
scaled_value = (x * (new_max - new_min)) + new_min
return scaled_value
r = 123
b = 231
g = 85
model = load_model('model.keras')
output = model.predict(np.array([b / 255, g / 255, r / 255]).reshape(1, -1))
hatch_um = int(scale_value(output[0][0], 1, 100))
power_mw = int(scale_value(output[0][1], 1000, 20000))
pulse_us = int(scale_value(output[0][2], 2, 10))
speed_um_s = int(scale_value(output[0][3], 41666, 3333333))
