Scholarship and implementation in information and communication technologies for development (ICTD/ICT4D) have seen an exponential increase over the past decade. In spite of enormous headway in both research and application, ICTD lacks a clear unified framework that can guide contextually grounded user-focussed design of ICT. This shortcoming results largely from the field’s unusual placement a...

We present the design and optimization of a 30um CMOS Image Sensor (CIS) pixel. This pixel is embedded in a sensor working in burst mode at speeds up to 5Mfps and high resolution (0.7Meg). Such performance is achieved using two dimensional CCD Memory bank at each pixel which was manufactured using a 0.18um well established CIS Process. Keywords— CCD in CMOS, Buried Channel, Charge Transfer, Glo...

Central composite design (CCD) is widely applied in many fields to construct a second-order response surface model with quantitative factors help increase the precision of estimated model. When an experiment also includes qualitative factors, effects between and should be taken into consideration. In present paper, D-optimal designs are investigated for models where interact with, respectively,...

C F N Cowan A CCD-based p1•ogrammable transversal filter is described. The filter incorporates analogue weighting coefficients and multipliers in an econondc structure, suitable fol' high-density integration. The pel'formance of a monolithic~ 64-point prototype device is discussed~ and a 256-point ahip~ which is currently in development~ is reported, The limitations of this structure a1•e consi...

The Gaia satellite is a high-precision astrometry, photometry and spectroscopic ESA cornerstone mission, currently scheduled for launch in 2012. Its primary science drivers are the composition, formation and evolution of the Galaxy. Gaia will achieve its unprecedented accuracy requirements with detailed calibration and correction for CCD radiation damage and CCD geometric distortion. In this pa...

The design of a CCD image half-toner integrated monolithically on the focal plane with a 256 X 256 frame transfer imager is reported and the algorithm used is discussed. The imager/half-toner chip is projected to achieve a throughput of 30 frames per second.
