The time-domain Cartesian multipole expansion of electromagnetic fields.

Time-domain solutions of Maxwell's equations in homogeneous and isotropic media are paramount to studying transient or broadband phenomena. However, analytical solutions are generally unavailable for practical applications, while numerical solutions are computationally intensive and require significant memory. Semi-analytical solutions (e.

Design and development of an AAC app based on a speech-to-symbol technology.

The purpose of this paper is to present the design and the development of an Augmentative and Alternative Communication app that uses a speech to symbol technology to model language, i.e. to recognize the speech and display the text or the graphic content related to it.

Measuring sense of presence and user characteristics to predict effective training in an online simulated virtual environment.

Introduction: Virtual-reality solutions have successfully been used to train distributed teams. This study aimed to investigate the correlation between user characteristics and sense of presence in an online virtual-reality environment where distributed teams are trained. A greater sense of presence has the potential to make training in the virtual environment more effective, leading to the formation of teams that perform better in a real environment.

A gonadotrophin-releasing hormone agonist compared with expectant management after conservative surgery for symptomatic endometriosis.

Objective: To ascertain whether the frequency of pelvic pain recurrence is reduced and time to symptoms recurrence is prolonged in women with symptomatic endometriosis undergoing conservative surgery and post-operative hormonal therapy compared with women treated with surgery only. Pregnancy rates and time to conception in women wanting children were also evaluated.

Design: A multicentre, prospective, randomised controlled study.

[Use of nomegestrol acetate in the treatment of menstruation disorders. Our experience in 56 cases].

Objective: To investigate tolerability and efficacy of nomegestrol acetate, a new 19-nor-progesterone derivative, in the treatment of oligomenorrhea and amenorrhea; to compare this drug with didrogesteron, a widely-used spatial isomer of progesterone.

Methods: 56 women, aged 22 to 50, affected by menstrual disorders or premenstrual syndrome, entered the study. They were divided in two homogeneous groups by randomization.
