This work describes an activity that led to the realization of a modified NIST Microphone Array MarkIII. This system is able to acquire 64 synchronous audio signals at 44.1 kHz and is primarily conceived for far-field automatic speech recognition, speaker localization and in general for hands-free voice message acquisition and enhancement. Preliminary(More)
This paper presents an automatic method to obtain tissue complex permittivity values to be used as input data in the computer modelling for hyperthermia treatment planning. Magnetic resonance (MR) images were acquired and the tissue water content was calculated from the signal intensity of the image pixels. The tissue water content was converted into(More)
The analysis of lectures and meetings inside smart rooms has recently attracted much interest in the literature, being the focus of international projects and technology evaluations. A key enabler for progress in this area is the availability of Ambrish Tyagi has contributed to this work during two summer internships with the IBM T. appropriate multimodal(More)
This paper describes a multichannel acoustic data collection recorded under the European DICIT project, during the Wizard of Oz (WOZ) experiments carried out at FAU and FBK-irst laboratories. The scenario is a distant-talking interface for interactive control of a TV. The experiments involve the acquisition of multichannel data for signal processing(More)
Realistic numerical models of human subjects and their surrounding environment represent the basic points of radiofrequency (RF) electromagnetic dosimetry. This also involves differentiating the human models in men and women, possibly with different body shapes and postures. In this context, the aims of this paper are, firstly, to propose a female(More)
INTRODUCTION A correlation between node hypodensity assessed by means of computer tomography (CT) and resistance to both chemotherapy and radiation therapy (XRT) in advanced head and neck tumours has been suggested in the literature. The outcome of a retrospective series of 50 patients with head and neck squamous cell carcinoma (SCC) and cervical nodes(More)
INTRODUCTION Neck node metastases from an unknown primary carcinoma represent an infrequent but challenging problem for oncologists. The management of such patients is controversial, but radiotherapy alone or as part of a multimodal approach is often indicated. Patients with inoperable lesions usually receive radiotherapy alone at palliative doses. In an(More)
Patients who have inoperable or previously irradiated cervical recurrences, especially if very confined and alone, pose a challenging problem to the clinician. Low-dose irradiation and hyperthermia seems to be a promising method for salvage treatments in previously treated patients. In order to heat the vaginal apex, individualized prototype applicators(More)
