On South Bank : The Production of Public Space
(Ashgate Publishing, 2014-06) -
On straight words and minimal permutators in finite transformation semigroups.
(Springer, 2011)Motivated by issues arising in computer science, we investigate the loop-free paths from the identity transformation and corresponding straight words in the Cayley graph of a finite transformation semigroup with a fixed ... -
On symmetries and dynamics of exotic supermultiplets
(2021-01-27)Among the allowed representations of extended supersymmetry in six dimensions there are exotic chiral multiplets that, instead of a graviton, contain mixed-symmetry spin-2 tensor fields. Notably, an N = (4, 0) multiplet ... -
On Taking Children Seriously: Climate Strikes
(2019-04-29) -
On the [α/Fe]-[Fe/H] relations in early-type galaxies
(2018-10-01)We study how the predicted [α/Fe]-[Fe/H] relations in early-type galaxies vary as functions of their stellar masses, ages, and stellar velocity dispersions, by making use of cosmological chemodynamical simulations with ... -
On the alignment between the circumstellar disks and orbital planes of Herbig Ae/Be binary systems
(2011)Context : The majority of the intermediate mass, pre-main-sequence Herbig Ae/Be stars reside in binary systems. As these systems are young, their properties may contain an imprint of the star formation process at intermediate ... -
On the Application of Agile Project Management Techniques, V-Model and Recent Software Tools in Postgraduate Theses Supervision
(Elsevier, 2022-10-06)Abstract: Due to the nature of most postgraduate theses in control engineering and their similarities to industrial and software engineering projects, invoking novel project control techniques could be effective. In recent ... -
On the atmospheric limitations of ground-based submillimetre astronomy using array receivers
(2002-10)The calibration of ground-based submillimetre observations has always been a difficult process. We discuss how to overcome the limitations imposed by the submillimetre atmosphere. Novel ways to improve line-of-sight opacity ... -
On the ballast-sleeper interaction in the longitudinal and lateral directions
(2018-02-01)In service, railway tracks must withstand the transverse and longitudinal forces that are caused by running vehicles and thermal loads. The mechanical design that adopts any of the track models available in the technical ... -
On the binary frequency of the lowest mass members of the pleiades with hubble space telescope wide field camera 3
(2015-05-01)We present the results of a Hubble Space Telescope Wide Field Camera 3 (WFC3) imaging survey of 11 of the lowest mass brown dwarfs in the Pleiades known (25-40 MJup). These objects represent the predecessors to T dwarfs ... -
On the Boundaries of the m=2 Amplituhedron
(2022-12-23)Amplituhedra A_{n,k}^{(m)} are geometric objects of great interest in modern mathematics and physics: for mathematicians they are combinatorially rich generalizations of polygons and polytopes, based on the notion of ... -
On the capacity of ASTC-MIMO-OFDM system in a correlated Rayleigh frequency-selective channel
(Institute of Electrical and Electronics Engineers (IEEE), 2011-01-01)Algebraic Space-Time Codes (ASTC) for MIMO systems are based on quaternion algebras. Thanks to their algebraic construction, the ASTC codes are full-rank, full-rate and have the non-vanishing determinant property. These ... -
On the convergence of inhomogeneous Markov chains : Approximating equilibrium placements of flexible objects
(2001)This paper deals with the minimization of local forces in two-dimensional placements of flexible objects within rigid boundaries. The objects are disks of the same size but, in general, of different materials. Potential ...
