The Covid-19 pandemic suddenly claimed its existence with thousands of fatalities reported worldwide in just a few months. It has caused great concern and panic resulting to total halt in all activities particularly the economic sector. The lockdown has caused global economic contraction which has led to forecasted economic recession for the year 2

In the present paper we study forward Quantum Markov Chains (QMC) defined on Cayley tree. A construction of such QMC is provided, namely we construct states on finite volumes with boundary conditions, and define QMC as a weak limit of those states which depends on the boundary conditions. Using the provided construction we investigate QMC associate

The purpose for this study is to validate a model of student interactions (student-content, student-instructor and student-student interactions and vicarious interaction), information technology self efficacy and student achievement. Investigation of the relationships was undertaken with structural equation modeling analyses, in a study with 250 un

We propose the construction of a quantum Markov chain that corresponds to a “forward” quantum Markov chain. In the given construction, the quantum Markov chain is defined as the limit of finite-dimensional states depending on the boundary conditions. A similar construction is widely used in the definition of Gibbs states in classical statistica

In the present paper we continue our investigations started in [Accardi L. , Ohno, H. , Mukhamedov, F. , Quantum Markov fields on graphs, Inf. Dim. Analysis, Quantum Probab.

This paper aimed at examining the learning strategies constructs and to investigate the relationship between learning strategies and motivation in Arabic courses. The study uses a questionnaire as the information-gathering instrument, and the participants comprised students from two public universities in Peninsular Malaysia who are studying Arabic

The main aim of 3D mobile interactive navigation support is to offer end-users easier means of accomplishing basic and complex navigation tasks in a user friendly way. Unfortunately, not until the end-users make use of the end-product or prototype, their needs, preferences, and their true understanding will not be acknowledged. As a result of these

Dry machining is environmentally friendly, clean and safe to be performed. Regardless of decreasing tool life due to lack of lubricants, choosing dry machining over wet machining may be a wiser choice since the cost of purchasing and disposing the cutting fluids can contribute to a higher cost. Wear rates, tool wear intensities and material removal

Dry machining is an eco-friendly machining process and its importance in the manufacturing industries should be taken seriously. Machining without the use of any cutting fluid is becoming increasingly more popular due to concerns regarding the safety of the environment and reducing cost. Dry and wet turning of T6061 aluminium alloy was performed on

Dry machining is a clean machining process and it will be considered as a necessity for manufacturing industries in future.Dry machining is environmental friendly and safe to be performed. Regardless of decreasing tool life due to lack of lubricants, choosing dry machining over wet machining may be a wiser choice since the cost of purchasing and di
