The purpose of this thesis is to find out the most important promotional and communication strategies in financial services industry and to... 

The inferential approach, in contrast with classic model of coding-decoding, regards communication something more than the mere decoding of the received message, and points to the inference as a pivotal element for the discovery of the intentional meaning in a communication. This line of research was beginned with the works of Paul Grice in the literature of the pragmatics. His theory proposes its cooperation principle and conversational maxims for that aim.Relevance theory, while accepting the pivotal role of the inference, replaces cognitive principle of relevance with those Gricean rules. Hence, it proposes a more comprehensive explanation of communication, with more simplicity and... 

Blind Source Separation (BSS) aims to recover multiple source signals from mixtures without prior knowledge of the sources or the mixing process. This manuscript focuses on speech separation in convolutive mixtures, aiming to recover speech signals from mixtures that are linear combinations of the filtered versions of original signals. Most recent methods for blind source separation in both instantaneous and convolutive mixtures typically involve transforming time-domain mixed signals into the time-frequency domain using Short-Time Fourier Transform (STFT) and conducting the separation in this domain. Broadly, the separation process is followed by two main approaches. The first involves...
