University students increasingly use mobile devices in their studies, while during the COVID-19 pandemic, mobile technology supported learning was applied by many students. Exploring students’ mobile technology perceptions is an ongoing research issue. This pilot study aimed to explore postgraduate students’ perspectives on the benefits and learning possibilities of mobile devices’ usage in their studies. In total, 34 Greek postgraduate students participated, and they answered an online questionnaire. The students expressed positive, strong perceptions, indicating their awareness of mobile technology learning possibilities and educational benefits for their studies. Almost all students (94.1%) agreed that mobile technology should be used to connect postgraduate students with people, content, and resources, and that mobile devices bring new learning opportunities in a postgraduate programme. Isolated significant differences were observed with regard to age and postgraduate mode of study (more positive views were expressed for blended mode in comparison to face-to-face mode). Implications for tutors, educational practices, and university policies are discussed.

The purpose of this work is to define the Laplace transform and the Laplace inverse transformation, to describe their basic properties and to calculate the corresponding transforms of selected functions. To achieve these, the concept of the real function image is first defined, and in particular the conversion of the complex variable function. The examples used are initially pure mathematics, followed by reference to the practical application of these two transformations since they relate to the conversion of a continuous time signal into a complex variable function.

The inverse Laplace transform enables the solution of ordinary linear differential equations as well as systems of ordinary linear differentials with applications in the physical and engineering sciences. The Laplace transform is essentially an integral transform which is introduced with the help of a suitable generalized integral. The ultimate goal of this work is to introduce the reader to some of the basic ideas and applications for solving initially ordinary differential equations and then systems of ordinary linear differential equations.
