Optical communication systems are since the last 25 years the backbone of all international data and telecom communications. Up to now, more than 10 TBit/s can be distributed via one optical fiber in long-haul systems. This was realized by the use of highly parallel multi-channel...

The first measure one usually comes into contact with in undergraduate mathematical studies is the Lebesgue measure and seeing how it is applied to the Lebesgue integral to extend considerably the Riemann integral, it doesn’t take very much else to arouse one’s interest in the st...

The uncontrolled urban spread (urban sprawl) has both positive and negative implications. The adverse effects are more pronounced than its gains. Among others adverse effects is infrastructure provision (such as roads, etc.) which usually becomes a problem. This work examines the...

Aim: To develop a model of matter that will account for electro-gravity. Matter is characterized by force fields and in non-inertial and non-geodesic motion as a result of interactions. The measurement of how non geodesic a test particle is can be done by non-geodesic acceleratio...

The simplest six-dimensional treatment of the expanding Universe in the form a three-dimensional sphere appeared as a result of the intersection of three simplest geometrical objects of finite sizes in the six-dimensional Euclidean space – of three uniformly expanding five-dimens...

This paper argues that the requirement of applicableness of quantum linearity to any physical level from molecules and atoms to the level of macroscopic extensional world, which leads to a main foundational problem in quantum theory referred to as the “measurement problem”, actua...
