It has built and characterised a laser and It has learned what each of the components does. It has been able to run the laser in single-mode and stabilised it around a desired setpoint thanks to a PID controller that It has programmed. It has established a communication between the PID controller programmed in LabVIEW and Arduino Due, the DAC that It has chosen after comparing it with another candidate. It has learned some basics of how the LightCrafter 4500 DMD works. The projected light is the composition of the lights of three LED’s, each of which has a certain on-time. The mirrors chose to be in on- or off-stages depending to the amount of intensity that we want for each colour.

This study was an attempt to apply land-based GIS analysis for freshwater aquaculture planning in the Red River Delta of Vietnam. It was based on diverse data sources in order to help decision makers at the site and also to contribute to the modelling of selection processes for aquaculture development planning in the region.

The trajectory of the somatic membrane potential of a cortical neuron exactly reflects the computations performed on its afferent inputs. However, the spikes of such a neuron are a very low-dimensional and discrete projection of this continually evolving signal. We explored the possibility that the neuron's efferent synapses perform the critical computational step of estimating the membrane potential trajectory from the spikes. We found that short-term changes in synaptic efficacy can be interpreted as implementing an optimal estimator of this trajectory. Short-term depression arose when presynaptic spiking was sufficiently intense as to reduce the uncertainty associated with the estimate; short-term facilitation reflected structural features of the statistics of the presynaptic neuron such as up and down states. Our analysis provides a unifying account of a powerful, but puzzling, form of plasticity.

The study revealed 125 species of fishes in Manipur of which 95 species belonging to 48 genera and 22 families have ornamental value. Fifty percent of these belonged to the family Cyprinidae, 7% to Cobitidae, 5% to Sisoridae 7% to Balitoridae, 3% to Channidae, 8% to Bagridae, 2% each to Chandidae and Mastacembelidae. Species representation in other families (16%) includes 1.6% each in Belonidae, Nandidae, Notopteridae, Psilorhynchidae, Schilbeidae and 0.8% each in Amblydpitidae, Anabantidae, Aplocheilidae, Belonidae,Chacidae, Clupeidae, Mugilidae, Symbranchidae, Siluridae and Tetradontidae. The conservation status of fishes showed that 25.6% of them have not been evaluated, 21.6% are vulnerable, 16.0% are endangered and 2.4% are critically endangered. "Low risk near threatened" category amounted to 25.6% and only 6.4% in "low risk least concern" category. Hence a cautious and regulated approach needs to be adopted while promoting ornamental fish trade. Suitable strategies for developing a viable ornamental fish trade in the state are discussed.

Semi-intensive grow-out trials on monoculture of gulsha (Mysrus cavasius) were
conducted to assess the production potentials for the period of six months from March
through August 2002. Three stocking densities such as 40,000 (T-1), 50,000 (T-2) and
60,000/ha (T-3) were tested in three replications. The production of gulsha was 1,~·74±52,
1,535±71 and 1,370±60 in treatment-I, 2 and 3, respectively and they were significantly
different (p

To assess the production potentials of small indigenous fish species (SIS) in semi-intensive monoculture system, an experiment was carried out with Amblypharyngadan mala, Chela cachius and Puntius sophore. Three treatments each with three replications were tested with mola, chela and punti individually and the stocking density of each species was 100,000/ha. Organic fertilizer was applied to the ponds at the rate of 1,000 kg/ha at fortnightly and rice bran was supplemented daily at 3% of the total fish biomass. Partial harvesting was made after three months of stocking. Gross production of 805±52.94, 1,120±41.62 and 509±48.81 kg/ha, respectively for mola, chela and punti over a period of six months were obtained. The yield of punti was found to vary significantly (P < 0.05) from that of mola and chela.
