1 A comparison of the spectral properties of high temperature annealed long period gratings inscribed by fs laser, uv and fusion-arc
Kalli, Kyriacos Allsop, Thomas Webb, David J.,
Long period gratings have been inscribed in standard single mode fibre using a fs laser system, a fusion arc and a UV laser and a comparative study carried out of their thermal behaviour. The fs laser...

2 A decoupled architecture of processors with scratch-pad memory hierarchy
Michail, Harris Milidonis, Athanasios S. Alachiotis, Nikolaos,
We present a decoupled architecture of processors with a memory hierarchy of only scratch-pad memories, and a main memory. The decoupled architecture also exploits the parallelism between address comp...

3 A hierarchical approach to image registration using feature consensus and hausdorff distance
Kasparis, Takis Xu, Dongjiang,
This paper presents a new hybrid and hierarchical algorithm for aligning two partially overlapping aerial images. This computationally efficient approach produces accurate results even when large rota...

4 A Low-Power and High-throughput implementation of the SHA-1 hash function
Michail, Harris Kakarountas, Athanasios P. Koufopavlou, Odysseas G.,
The main applications of the hash functions are met in the fields of communication integrity and signature authentication. A hash function is utilized in the security layer of every communication prot...

5 A visual-servoing scheme for semi-autonomous operation of an underwater robotic vehicle using an IMU and a laser vision system
Loizou, Savvas Karras, George C. Kyriakopoulos, Kostas J.,
This paper presents a visual servoing control scheme that is applied to an underwater robotic vehicle. The objective of the proposed control methodology is to provide a human operator the capability t...

6 Adaptive DSP algorithm for calibrating drop size distribution rain gauges
Kasparis, Takis Lane, John E. McFarquhar, Greg M.,
The calibration of impact disdrometers has traditionally been a tedious process, whereby known diameter single water droplets are generated and allowed to fall from a height of 10 meters or more in or...

7 Adaptive transform coding of images using approximate trigonometric expansions
Kasparis, Takis Memon, Qurban A.,
The objective behind transform coding is to transform a data array into a statistically uncorrelated set. The uneven distribution of energy in transform coefficients is exploited for compression purpo...

8 Alternative device concepts for future requirements of organic photovoltaic cells
Choulis, Stelios A. Waldauf, Christoph Denk, Patrick,
The challenge to reversing the layer sequence of organic photovoltaics (OPVs) is to prepare a selective contact bottom cathode and to achieve a suitable morphology for carrier collection in the invert...

9 Annealing and temperature coefficient study of type ia fibre bragg gratings inscribed under strain and no strain - implications to optical fibre component reliability
Kalli, Kyriacos Simpson, George Webb, David J.,
The annealing properties of Type IA Bragg gratings are investigated and compared with Type I and Type IIA Bragg gratings. The transmission properties (mean and modulated wavelength components) of grat...

10 Application of approximate trigonometric expansions to multiresolution signal representation
Kasparis, Takis Memon, Qurban A.,
Signal representation and data coding for multidimensional signals have received considerable attention due to their importance to several modern technologies. Many useful contributions have been repo...
