  • Energy levels and reduced transition probabilities of 18-20F isotopes
           using USDA and W Hamiltonians

    • Abstract: Energy levels for (18F, 19F and 20F) isotopes have been studied within the framework of shell model using OXBASH code. In this work, the calculations are based on the Universal Sd-shell Hamiltonian (USDA) and W Hamiltonians for proton and neutron particle orbits in SDPN model space. The calculated energy levels and reduced electric quadrupole transition probabilities B(E2;) are in reasonably...

  • Investigation of possible cause of gravity anomalies in parts of the Niger
           Delta Basin, Nigeria

    • Abstract: Possible cause of gravity anomalies in parts of the Niger Delta Basin, Nigeria was investigated using three methods of gravity data interpretation; Euler-3D deconvolution, source parameter imaging (SPI) and forward and inverse modeling. The estimated depths from the interpretation techniques used show much similarity. Quantitatively, the results obtained from the SPI method showed a minimum ...

  • Determinations of norfloxacin complexes with caffeine, and its optical
           transition probabilities using UV-Vis spectroscopy

    • Abstract: The optical transition probabilities and hetero-association of caffeine with norfloxacin were obtained using UV-Vis spectroscopy in aqueous solution at room temperature (295K). The heter-association constant of norfloxacin-caffeine complexes (6.67103 M-1) was obtained using Benesi-Hildebrand approach by linear curve fitting to the experimental data. In order to characterize the binding syste...

  • Doppler fading communication channel performance simulation

    • Abstract: Fading is commonly used to describe the properties of the communication channel. Large efforts have been made to describe characteristics of the channel in wireless communication system. The performance of wireless signal propagation in a conventional environment needs Doppler fading channel schemes by assuming a perfect knowledge about the channel frequency response at both the transmitter ...

  • Application of data mining in telecommunication industry

    • Abstract: This paper applied a data mining model in sales and marketing department of Telecommunication Industry (TI) in Nigeria. The motivation behind the paper is as a result of competitive challenges facing most TI sales and marketing departments globally such as inability in gaining precise view of targeted data, inability to translate and formulate business question correctly and Problem of addre...

  • Pressure and temperature effects on corona onset voltage in electrostatic
           precipitators

    • Abstract: Corona onset voltage is one of the most important factors that determine the charging toxic particle in an industrial application. Electrostatic precipitators (ESP) remove the suspended particle with a gas inlet. This paper developed Peeks formula to estimate the maximum electric field near the discharge wire in corona discharge models, the values of maximum electric field and corona onset v...

  • Hydrogeochemical investigation and characterization of shallow groundwater
           within Ankpa Town, North Central Nigeria

    • Abstract: Physico-chemical analysis of groundwater samples from Ankpa, north central Nigeria was carried out to investigate the quality of the water for drinking and irrigation purposes. The results revealed water of average low pH, indicating slightly acidic conditions of the water. The water is soft, and it is characterized as Na++K - HCO3 type. It is good for drinking and other domestic uses. Four ...

  • Performance evaluation of law enforcement agency on crime information
           management using queuing network model

    • Abstract: One of the greatest challenges facing every society today is crime control and management. It could be as little as pickpocketing, or human trafficking, or even as deadly as terrorism. As criminals perfect ways of avoiding being detected, Law Enforcement Agencies (LEAs) must adopt innovative ways on crime prevention and control. This research applies Queuing Network (QN) model to evaluation ...

  • Effect of Co component in Co-Ag granular thin films on visible-light
           reflection applied by magnetic field

    • Abstract: The reflection of visible light (wavelength from 350 to 800 nm) on magnetic granular thin films Cox-Ag1-x with x from 0 to 35 at % was studied. Dependence of reflection (R) is strong on magnetic and percentage of Co in the thin films, R strongly increase in wavelengths 560 and 660 nm. In this paper, some arguments relating to the spin-plasmon phenomenon were used to explain the results. ...

  • Partial and total mass attenuation coefficients, effective atomic number
           and effective electron number of different Maraging steel compositions

    • Abstract: The total and partial mass attenuation coefficients for different Maraging steel compositions have been determined by using the WinXCom and MCNP5 programs. The effective atomic number, Zeff, and effective electron number, Neff, for the studied steels have been determined via the total mass attenuation coefficients /, the total atomic and electronic cross sections (a and e) of the investigate...
