Place branding and the Liverpool ’08 brand campaign in 'City of Liverpool'
Place branding brings together a range of existing specialisms, in particular those of brand management and development policy, to create a new discipline with equal emphasis on visionary strategy and hands-on implementation.1 Furthermore, Place branding ensures that the place gets due credit for its real strengths and positive behaviour, and that the place brand gains appropriate equity from the recognition,
which that behaviour deserves
On the Long-range Dependence of Fractional Poisson and Negative Binomial Processes
We study the long-range dependence (LRD) of the increments of the fractional
Poisson process (FPP), the fractional negative binomial process (FNBP) and the
increments of the FNBP. We first point out an error in the proof of Theorem 1
of Biard and Saussereau (2014) and prove that the increments of the FPP has
indeed the short-range dependence (SRD) property, when the fractional index
satisfies . We also establish that the FNBP has
the LRD property, while the increments of the FNBP possesses the SRD property.Comment: 17 page
Modeling Financial System with Interbank Flows, Borrowing, and Investing
In our model, private actors with interbank cash flows similar to, but nore
general than (Carmona, Fouque, Sun, 2013) borrow from the outside economy at a
certain interest rate, controlled by the central bank, and invest in risky
assets. Each private actor aims to maximize its expected terminal logarithmic
utility. The central bank, in turn, aims to control the overall economy by
means of an exponential utility function. We solve all stochastic optimal
control problems explicitly. We are able to recreate occasions such as
liquidity trap. We study distribution of the number of defaults (net worth of a
private actor going below a certain threshold).Comment: 27 pages, 29 figures. Keywords: systemic risk, stochastic control,

Optimal Quantization of TV White Space Regions for a Broadcast Based Geolocation Database
In the current paradigm, TV white space databases communicate the available
channels over a reliable Internet connection to the secondary devices. For
places where an Internet connection is not available, such as in developing
countries, a broadcast based geolocation database can be considered. This
geolocation database will broadcast the TV white space (or the primary services
protection regions) on rate-constrained digital channel.
In this work, the quantization or digital representation of protection
regions is considered for rate-constrained broadcast geolocation database.
Protection regions should not be declared as white space regions due to the
quantization error. In this work, circular and basis based approximations are
presented for quantizing the protection regions. In circular approximation,
quantization design algorithms are presented to protect the primary from
quantization error while minimizing the white space area declared as protected
region. An efficient quantizer design algorithm is presented in this case. For
basis based approximations, an efficient method to represent the protection
regions by an `envelope' is developed. By design this envelope is a sparse
approximation, i.e., it has lesser number of non-zero coefficients in the basis
when compared to the original protection region. The approximation methods
presented in this work are tested using three experimental data-sets.Comment: 8 pages, 12 figures, submitted to IEEE DySPAN (Technology) 201
