A method for locating auditory brain stem implant electrodes that have been placed in the lateral recess of the fourth ventricle is described. CT bone window images are "inverted" to black on white, then manually superimposed onto soft-tissue window images to enable identification of electrodes in relation to soft-tissue structures.

OBJECTIVE To compare the difference in mean stone size, as measured on bone window vs standard soft-tissue window setting using multi-detector computed tomography (MDCT) in patients with a solitary ureteric stone. PATIENTS AND METHODS In all, 60 patients presenting to the emergency and outpatient departments of a University Hospital from May 2015 to October 2015 and fulfilling the inclusion c...

Rectification and reactive distillation columns are the main of all units in petrochemical refining industry. Soft sensors consist mathematical models that estimate quality an output product real time used for technological processes control. In general, changes composition raw materials, catalyst deactivation, etc. result inconsistency between obtained data current state process. sensor design...

Customer service level is of prime importance in today competitive world and has various dimensions with delivery quality being one of the most important ones. Delivery quality has several parameters such as deliver time window options, time window size, etc. In this paper we focus on one of these parameters, namely time window setting. It has a direct impact upon customer satisfaction and busi...

This paper considers the VRP Problem with Soft Time-Windows (VRPSTW), a challenging routing problem due to its combination of hard time windows and a lexicographic objective function minimizing the number of vehicles, the violations of the soft time windows, and the total travel distance. The paper presents a multi-stage, variable neighborhood search algorithm for the VRPSTW, which uses the sam...

optimal attributes are useful in interpretation of seismic data. two proposed methods are presented in this paper for finding optimal attributes. regularized discriminate analysis(rda) is based on 2 parameters ë, ? which called regularization parameter. the other method is principal component analysi s(pca).in this paper gas chimney detection is defined as the subject of study for ranking relev...
