    Abstract: Pakistan, like other developing countries, is facing the growing problem of traffic noise pollution of the modern world. It is a notable problem of urban areas of the country including Quetta city. The basic cause of this problem is the tremendous increase in traffic volume and lack of proper town planning. This study is the first proper attempt to... Show More

    Abstract: Thermoelectric properties of the single molecular magnet coupled to two metal electrodes are investigated theoretically. For the infinite Coulomb interaction the singly-occupied states determine the effective transport channels. At the low temperature the thermopower and the figure of merit present the large values near bonding state level, and for... Show More

    Abstract: A lower resistivity and better spectra selectivity is a measurement of the quality and potential use of silver Ag and aluminium Al metals for the application as metallization contacts for solar cells. Aluminium (Al) and silver (Ag) thin films deposited by thermal evaporation at room temperature were dense with small grain sizes, and maintained a ... Show More
  • Relativistic Energy and Mass Originate from Homogeneity of Space and Time and from Quantum Vacuum Energy Density

    Abstract: In a previous paper we have shown it is possible to build alternative versions of Special Theory of Relativity only considering homogeneity of space, of time and Relative Principle without invoking the postulate of invariance of light velocity in all the inertial frames. Within these alternatives, space and time transformations different than the L... Show More

    Abstract: A single field emerged at the origin of the universe, already containing within itself the blueprint of the physical universe. The primordial single field triggered the onset of the universe. Most physicists believe that a single super-force dominated the first instants of creation. Scientists have arrived at a simple but decisive conclusion that c... Show More

    Abstract: The ground state properties of the two-electron atom with atomic number in the spherical vacuum cavity with general boundary conditions of “not going out” are studied. It is shown that for certain parameters of the cavity such atom could either decay into the one-electron atom with the same atomic number and an electron or be in stable state with... Show More

    Abstract: Based on pioneering works by Sciama and Kibble to extend Einstein-Cartan theory of gravity we give a new derivation for the cosmic energy density. It is argued that the ‘t Hooft-Veltman and Wilson method of renormalization implies the relativity of fractal spacetime at the quantum scale and a dark energy density of E(D) = 95.5 percent. It is furth... Show More

    Abstract: Polynomial distribution can be applied to dynamic systems in certain situations. Macroeconomic systems characterized by economic variables such as income and wealth can be modelled similarly using polynomials. We extend our previous work to data regarding income from a more diversified pool of countries, which contains developed countries with high... Show More

    Abstract: Whereas the basic physical mechanisms leading to the onset and evolution of tornadoes have been well established, some progress can still be useful to identify the conditions supporting the development of a tornado towards a violent or catastrophic stage, as well as possible specific and observable events triggering the onset of a tornado in a gene...

    Abstract: One transformation, analogy to two mode approximation, is presented for triple-square wells. The energy splitting is determined by the strength of the tunneling coupling between nearest neighbor wells, while the next-nearest neighbor tunneling coupling plays crucial role to the invariant first excited state with the maximum entanglement states for ...
