A hi-tech company often focuses on being innovative by providing product offerings as product leader, fast follower or with operational excellence. In the international calling sector the technological solutions are numerous. The providers are, for instance, normal telecom providers, Voice over Internet Protocol (VoIP) and Mobile virtual network operators (MVNO). This means that a company faces not only the competitors that offer the same solution but also from outside the company’s business sector. The company thus needs to tackle many challenges, such as fast-paced product development, market expansion, competitor volatility, at the same time as the company cultivates its brand assets. This study focuses on the branding strategy within the VoIP telecom sector. It aims to set a guideline for how companies, in particular in the VoIP telecom sectors, cultivate and enhance their brand identity in order to differentiate themselves from competitors as well as achieve a successful and sustainable level of brand equity. The thesis also studies the brand strategies that have already manifested themselves within the providers of international calling services, in particular VoIP providers and a couple of MVNO providers. By conducting the brand identity and brand equity analysis, customer analysis and competitors’ analysis, a company can make a decision on brand strategy that will further associate, differentiate, energize and support its brands. The research framework consists of both the corporate and consumer perspectives. It consists of brand theory, market research, competitor analysis and the company’s brand identity, as well as brand awareness analysis. The thesis presents the Swedish VoIP consumers’ behavior and trends, the guideline and case study on how a company bridges the gap between brand identity and brand equity as well as the guideline and case study of brand portfolio strategies that have been explored within the VoIP telecom sectors, i.e. VoIP branding
Polarization Effects in Chargino Production at High Energy Colliders
We investigate the chargino production process
at high energy
colliders in the framework of the minimal supersymmetric
standard model (MSSM). Here the high energy beams are obtained by the
backward Compton scattering of the laser flush by the electron in the basic
linear TeV colliders. We consider the polarization of the laser photons as
well as the electron beams. Appropriate beam polarization could be effective to
enhance the cross section and for us to extract the signal from the dominant
background .Comment: 7 pages, latex , 3 figures are available upon reques
Relativistic Quantum Thermodynamics of Ideal Gases in 2 Dimensions
In this work we study the behavior of relativistic ideal Bose and Fermi gases
in two space dimensions. Making use of polylogarithm functions we derive a
closed and unified expression for their densities. It is shown that both type
of gases are essentially inequivalent, and only in the non-relativistic limit
the spinless and equal mass Bose and Fermi gases are equivalent as known in the
literature.Comment: 6 pages, 1 figur
Custodial SO(4) symmetry and CP violation in N-Higgs-doublet potentials
We study the implementation of global
symmetry in general potentials with N-Higgs-doublets in order to obtain models
with custodial symmetry. We conclude that any implementation of the
custodial SO(4) symmetry is equivalent, by a basis transformation, to a
canonical one if is the gauge factor, is embedded in
and we require copies of the doublet representation of .
The invariance by SO(4) automatically leads to a CP invariant potential and the
basis of the canonical implementation of SO(4) is aligned to a basis where
CP-symmetry acts in the standard fashion. We show different but equivalent
implementations for the 2HDM, including an implementation not previously
considered.Comment: 22pp, REVTeX4. Published versio
Zero gravity and cardiovascular homeostasis. The relationship between endogenous hyperprolactinemia and plasma aldosterone
Prolactin, thyrotropin and aldosterone were measured by radioimmunoassay and plasma renin activity by the radioimmunoassay of angiotensin I in normal women before and after the intravenous injection of 200 micrograms of thyrotropin releasing hormone. Prolactin increased at 15 minutes following thyrotropin releasing hormone. Plasma renin activity was not different from control levels during the first hour following the administration of thyrotropin releasing hormone, nor did the plasma aldosterone concentration differ significantly from the control levels during this period. However, with upright posture, an increase in aldosterone and in plasma renin activity was noted, demonstrating a normal capacity to secrete aldosterone. Similarly, no change in aldosterone was seen in 9 patients with primary hypothyroidism given thyrotropin releasing hormone, despite the fact that the increase in prolactin was greater than normal. These data demonstrate that acutely or chronically elevated serum prolactin levels do not result in increased plasma aldosterone levels in humans
Presymmetry beyond the Standard Model
We go beyond the Standard Model guided by presymmetry, the discrete
electroweak quark-lepton symmetry hidden by topological effects which explain
quark fractional charges as in condense matter physics. Partners of the
particles of the Standard Model and the discrete symmetry associated with this
partnership appear as manifestations of a residual presymmetry and its
extension from matter to forces. This duplication of the spectrum of the
Standard Model keeps spin and comes nondegenerated about the TeV scale.Comment: 6 pages, 11 figures. To be published in the proceedings of DPF-2009,

Radiative Corrections to the Higgs Boson Mass for a Hierarchical Stop Spectrum
An effective theory approach is used to compute analytically the radiative
corrections to the mass of the light Higgs boson of the Minimal Supersymmetric
Standard Model when there is a hierarchy in the masses of the stops (M_st1 >>
M_st2 >> M_top, with moderate stop mixing). The calculation includes up to
two-loop leading and next-to-leading logarithmic corrections dependent on the
QCD and top-Yukawa couplings, and is further completed by two-loop
non-logarithmic corrections extracted from the effective potential. The results
presented disagree already at two-loop-leading-log level with widely used
findings of previous literature. Our formulas can be used as the starting point
for a full numerical resummation of logarithmic corrections to all loops, which
would be mandatory if the hierarchy between the stop masses is large.Comment: 42 pages, LaTeX, 13 figure
