In this paper we discuss the problem of signal reconstruction from spectral magnitude or phase using group delay functions. We define two separate group delay functions for a signal, one is derived from the magnitude and the other from the phase of the Fourier transform of the signal. The group delay functions offer insight into the problem of signal reconstruction and suggest methods for recon...

This study builds on Laufer and Hulstijn’s (2001) motivational-cognitive construct of task-induced involvement in learning vocabulary and addresses itself to its strong claim that the depth of processing is the overriding factor in learning words. The paper first re-examines the effect of processing load and then of task type on the initial learning and retention of words. To do so, 60 EFL lear...

We give sharp criteria for when a reductive group scheme satisfies Tannakian reconstruction. When the base is Noetherian, we explicitly identify its Tannaka scheme.

BACKGROUND Computer-assisted surgery plays an increasingly important role in mandibular reconstruction, ensuring the best possible masticatory function and aesthetic outcome. METHODS Twenty patients were randomly assigned to computer-assisted or conventional mandibular reconstruction with vascularized iliac crest bone graft in a prospective study design.Virtual surgical planning was based on ...

Group size in both multicellular organisms and animal societies can correlate with the degree of division of labour. For ants, the task specialization hypothesis (TSH) proposes that increased behavioural specialization enabled by larger group size corresponds to anatomical specialization of worker brains. Alternatively, the social brain hypothesis proposes that increased levels of social stimul...

Microlending, where a bank lends to small group of people without credit histories, began with the Grameen Bank in Bangladesh, and is widely seen as creation Muhammad Yunus, who received Nobel Peace Prize recognition his largely successful efforts. Since that time modeling microlending has fair amount academic attention. One issues not yet addressed full detail, however, issue size group. Some ...
