In this paper we run two important methods for solving some well-known problems and make a comparison on their performance and efficiency in solving nonlinear systems of equations‎. ‎One of these methods is a non-monotone adaptive trust region strategy and another one is a scaled trust region approach‎. ‎Each of methods showed fast convergence in special problems and slow convergence in other o...

Region inference is a type-based technique for determining runtime memory management at compile time. It is targeted at a runtime model in which the store consists of a stack of regions and memory management predominantly consists of pushing and popping regions. Region inference has previously been speciied by a set of inference rules, which formalize when regions may be allocated and deallo-ca...

The management of pineal region tumors has changed considerably since the introduction of microsurgery and CT scanning. Analysis of our own series of 36 patients, comparing those treated in the pre-CT scan and microsurgery era with those treated afterwards, shows the important role these two techniques play. Current controversies in treatment and our own approach to management of pineal region ...

The pineal region can be affected by different types of lesions, ranging from benign masses (e.g. pineal cysts) to highly malignant tumors. These neoplasms are typical of the pediatric age, while they are rarer in adults. Due to the extreme heterogeneity of the cell types of the pineal gland and its surrounding structures, these tumors include several entities, namely germ cell tumors (GCTs), w...

In this paper, we concentrate on determining homogeneously colored regions invariant to surface orientation change, illumination, shadows and highlights. To this end, the influence of various well-known color models (e.g. I , RGB, XY Z, I1I2I3, rgb, xyz, U V W , L a b and ISH) are examined, in theory, for the dichromatic reflection model and, in practice, for two distinct region-based segmentat...
