The present research was conducted to evaluate the quality of training services in maritime training centers of Khuzestan province (including DARYAYE DOOR, SERAJ DARYA and DARYA PEIMAYE GENAVE). For this purpose, SURVQUAL model was used. The research is of descriptive-field study type for which 110 trainees of maritime training centers of Khuzestan province were selected via stratified ra...

A notion of dimensional dual polar spaces of polar type is given with a family of new examples. Nonexistence is shown for those of dimension 3, while there are just two isomorphism classes for those of dimension 2.

We consider suspension flows over two-sided subshifts of finite type and establish an explicit formula for the pointwise dimension of an arbitrary measure (in particular the measure is not necessarily ergodic and it may not possess a local product structure). The applications of this formula include the description of the Hausdorff dimension of a given measure in terms of an ergodic decompositi...

OBJECTIVES There are four types of signals that are typical representations of vocal fold vibratory patterns. Type 1 signals are nearly periodic, type 2 signals contain subharmonic properties, type 3 signals are chaotic, and type 4 signals are characterized as white noise. High-speed imaging allows detailed observation of these vocal fold vibratory patterns. Therefore, high-speed imaging can ex...

There are remarkable relations between the graded homological dimensions and the ordinary homological dimensions. In this paper, we study the injective dimension of a complex of graded modules and derive its some properties. In particular, we define the $^*$dualizing complex for a graded ring and investigate its consequences.

Micro size craters were created by interaction of nanosecond laser beam with titanium target in liquid media. The dimension of crater i.e. depth and width is important in some applications such as micromachining. When the interaction occurs in liquid environment, the ablated materials from the target expand into the liquid. The ablated material can affect the interaction process if the ablated ...
