A novel rapid acquisition algorithm, called sequential block search, is proposed for impulse radio systems, which can reduce the mean acquisition time considerably. The algorithm is compared to the conventional serial search algorithm and output statistics for both algorithms are derived for a binary phase-shift keyed random time hopping impulse radio system. The mean acquisition time formulas are

Prosodic and lexical correlates of ‘clause-like’ and ‘paragraph-like’ boundaries associated with the Swedish discourse marker men ‘but/and/so’ are examined. Men-tokens in spontaneous monologues were labelled as to their boundary-status, first using text-only data. The ‘strong’ tokens (labelled identically by all labellers) were subsequently seen to be correlated with clear differences in the proso

In this paper I draw on two case studies of how environmental impacts are assessed in large scale golf developments to illustrate the political ecology of leisure and how countrysides are reshaped to cater for elite consumption (McCarthy 2008). In 2008 Trump International Golf Links Scotland gained permission to build a golf resort, potentially the largest in the UK, along the Aberdeenshire coast.

Objective: To evaluate long-term oncological outcome and surgical quality of robotic radical hysterectomy for cervical cancer. Methods: Consecutive women with stage IA2 to IIA operated between March 2006 and May 2012 with a robotic radical hysterectomy and pelvic lymphadenectomy were prospectively followed up until five years after surgery or until death. Details regarding clinical results, recurr

In this paper we present two different ways of reducing the radar cross section (RCS) of thin metallic wires at low frequencies. This reduction is achieved by adding a dielectric coating on the wire. The entire cylindrical structure is finally protected by a thin exterior non-magnetic dielectric layer (eagle skin). The contribution to the RCS has either an electric or an magnetic origin. To reduce

The conclusions in this paper are drawn from the results of four empirical studies. It has been important to take an empirical approach in the investigation, concerned with internationalization of higher education, since even though plentiful of studies over the last decades have been concerned with internationalization in/of higher education, it has not been from the perspectives from the teacher

Highly excited P and D states in 87 Rb were examined using a two-step excitation procedure. A conventional rf lamp and a CW dye laser were used for the first and second step, respectively. The following results for the magnetic dipole interaction constant a , the electric quadrupole interaction constant b , the Landé g J factor, and the tensor polarizability α 2 were obtained in level-crossing an

Vid medicinska fakulteten i Lund forskar man inte bara inom medicin, det forskas även om lärande och undervisning. Vi har intresserat oss för denna utbildningsvetenskapliga forskning och velat ta reda på vad den handlar om, hur den relaterar till fakultetens utbildningsverksamhet, samt varför den har genomförts. Särskilt har vi undrat om forskningen är att betrakta som SoTL, dvs Scholarship of Tea

DIRECT is a sample-based global optimisation method for Lipschitz continuous functions defined over compact multidimensional domains. This paper adapts the DIRECT method with a modified termination criterion for global extremum seeking control of multivariable dynamical plants. Finite-time semi-global practical convergence is established based on a periodic sampled-data control law, whose sampling
