One of the most interesting realm among those ones brought up to success by the development of the Internet is Distance Learning. A key issue in such a field is the development of systems for supporting Tutoring activities. This paper is concerned with the presentation of an innovative architecture for Intelligent Tutoring which make use of Software Agents.(More)
OBJECTIVE To report a case of cervical radiculopathy caused by an anomalous vertebral artery (VA) and illustrate the efficacy of microvascular decompression by the anterolateral approach. METHODS A 50-year-old woman was referred because of an 8-year history of progressive left C6 radiculopathy refractory to other forms of treatment, including C5-6(More)
The purpose of this paper is to describe an Intelligent Tutoring Framework highly re-usable and suitable to several knowledge domains. In particular the system, named ABITS, has been realized in the context of the InTraSys ESPRIT project. It is able to support a Web-based Course Delivery Platform with a set of " intelligent " functions providing both(More)
OBJECTIVES Sellar lesions, such as pituitary adenomas, even when extended to the suprasellar space may be usually removed through a trans-sphenoidal approach. Larger lesions extending well beyond the edges of the sellar diaphragm such as giant adenomas are best controlled with craniotomy and/or a combined approach that implies both, transphenoidal and(More)
OBJECTIVE AND IMPORTANCE Spontaneous spinal subarachnoid hematoma is rare, having been reported in the English literature in only seven other cases. We describe the first case of spontaneous subarachnoid hematoma located in the cervical spinal cord of a 43-year-old man. The pathologic examination showed no apparent source of bleeding, but there was evidence(More)
OBJECTIVES Transtentorial brain herniation is a major cause of morbidity and death following severe closed head injury. The purpose of this study was to evaluate the efficacy of selective uncoparahippocampectomy and tentorial splitting as an adjuvant method of treating otherwise uncontrollable elevated intracranial pressure (ICP) while attempting to prevent(More)
Recently the debate over the management of cervical spondylotic myelopathy (CSM) has regained interest; more specifically whether treatment should be operative versus non-operative, raising the question about the real effectiveness of surgery in influencing the natural history of this pathology and about the choice of the most appropriate approach (anterior(More)
The authors report an interesting case with a ruptured internal carotid artery aneurysm that presented as a sellar haematoma mimicking radiologically a pituitary adenoma, and clinically a pituitary apoplexy. A 53-year-old woman presented with a 2-week history of episodic severe headache and vomiting associated, 3 days prior to admission, with left(More)
The main goal of the project called Socratenon was to build a new Web-based training environment that would go beyond traditional ones. In the open literature, there are several solutions trying to accomplish the same to a certain degree. Some of them are nothing more but plain virtual textbooks that only flip pages on mouse-clicks. More sophisticated(More)
The purpose of this paper is to introduce Artificial Intelligence in the field of data-security and to propose an easy to implement Neural Networks based method for user authentication. The problem has been faced exploiting an RBF-like Neural Net to recognize the typing style of users asking for connection. The introduction of Neural Nets allows to extract(More)
