An anatomical-angiographic classification for carotid-cavernous sinus fistulas is introduced and a series of 14 patients with spontaneous carotid-cavernous sinus fistulas is reviewed to illustrate the usefulness of such a classification for patient evaluation and treatment. Fistulas are divided into four types: Type A are direct high-flow shunts between the internal carotid artery and the caver...

the purpose of this study was to evaluate the performance of organization branches in tehran  by using the hybrid method topsis, ahp, bsc, so that the deficiencies of such a subjective and selective attention leaders (assessors) in the evaluation and integration of yield loss with in terms of the contribution of each group to achieve the goals to provide bsc. in this study, a multi-criteria dec...

This paper proposes a new approach for gauging the performance of branch managers of a financial institution by defining a Measure of Internal Performance (MIP). Our proposal is different from others existing in the literature in two main aspects. Firstly, it is consistent with the requirements of internal evaluation because it uses the managers’ real preferences instead of assuming them. Secon...

Visualization of aortic arch branches by transesophageal echocardiography has been technically challenging. Visualizing these vessels helps in identifying the extent of dissection of the aorta, assessing the severity of carotid artery stenosis, presence of atheromatous plaques, patency of the left internal mammary artery graft, confirmation of subclavian artery cannulation, confirming holodiast...

The performance evaluation of bank branches is a difficult task. One of the main reasons for this difficulty is the complexity inherent in the variety of aspects to be considered in the evaluation, and the multiple and conflicting interests of the different stakeholders involved. In this paper we aim to show how cognitive mapping and the MACBETH approach can be used to support the evaluation of...

This paper gives an overview of promising new developments in robust stability and performance analysis of linear control systems with real parametric uncertainty. The goal is to develop a practical algorithm for medium size problems, where medium size means less than 100 real parameters, and \practical" means avoiding combinatoric (nonpolynomial) growth in computation with the number of parame...
