Engineering Mathematics Education With Computer Algebra: The Matlab Alternative

Professor James Katende
Computer algebra systems have become an important tool for many engineering and technical professionals. There is a growing need to incorporate such tools into the education of such professionals. This paper discusses these systems and their role within engineering mathematics in higher education. Some advantages and problems associated with computer algebra are highlighted and illustrated usin...

Design of Sliding Mode Orbit Controllers For Communications Satellites

Professor James Katende
A geostationary communications satellite drifts gradually out of its correct orbital position under a variety of influences, notably solar winds and the irregular distribution of gravities of Moon and Earth. Thus its orbital position must be corrected from time to time to ensure proper communications and to avoid interference with other satellites’ signals. This has to be done taking into accou...

One-minute rain rate distribution in Nigeria derived from TRMM

T.V. Omotosho, C.O. Oluwafemi (2009)
Data from the Tropical Rainfall Measuring Mission (TRMM) satellite sensors, the Microwave Imager (TMI, 3A12 V6) and other satellite sources (3B43 V6) have been used to derive the thunderstorm ratio b, total rain accumulation M, and 1-min rainfall rates, R1min, for 37 stations in Nigeria, for 0.001–1% of an average year, for the period 1998–2006. Results of the rain accumulations from the TRM...

Impairment of radio wave signal by rainfall on fixed satellite service on earth–space path at 37 stations in Nigeria

T.V. Omotosho, C.O. Oluwafemi(2009)
This study investigates the effect of rainfall on horizontally polarized radio waves for fixed satellite service at Ku, Ka and V bands for links to the recently launched Nigeria Communication Satellite one (NigComSat-1), for annual time availabilities of 99–99.99% in an average year for 37 stations in Nigeria. The results obtained at Ku-band downlink shows that 99.99% availability is possibl...

Solar Activity and Total Ozone variation in Lagos

A.B Rabiu and T.V Omotosho (2003)
Impacts of solar activity on the total column ozone variation within an interval of four years (1993-1997) have been investigated at an equatorial station of Lagos (06°33' N, 03°21' E) Nigeria. The linear regression analysis shows a significant negative correlation between mean total column ozone and solar activity both at monthly level (r = -0.0652, r2 = 0.0043) and annual level (r = -0.2671,...

Study of Cloud Impact on Fixed Satellite Communication Link at Ku, Ka and V Bands in Nigeria

T.V. Omotosho, E.B. Babatunde (2010)
The study investigates the effect of clouds on fixed satellite communication link on earthspace path in Nigeria for 0.01 to 10% unavailability of an average year. The input data (from August 2002 to July 2009) used for the study are base on recent meteorological data measured from space by the Atmospheric Infrared Sounder satellites (AIRS). The International Telecommunication Union Radio Pr...

Rain-induced cross-polarization effects o satellite telecommunication in some tropical locations

T.V Omotosho and M.O Ajewole (2005)
Rain- induced cross polarization is an important factor in the design of dual-polarization microwave radio communication systems. In this work we present the scattering effect of oblate spheroidal raindrops on Earth-space wave communication in the frequency band 1–52 GHz in three tropical locations: Ile-Ife, Nigeria (4.340E, 7.330N), Douala, Cameroon (9.700E, 4.050N), and Nairobi, Kenya (36.750...

SIGNATURE OF ATMOSPHERIC DYNAMICS ON SURFACE OZONE VARIABILITY IN NIGERIA

Akinyemi M L and T V Omotosho (2010)
An examination of analysis revealed that surface ozone concentration over Nigeria varied with direction of the local trade winds, namely the Harmatan, and the Gulf of Guinea maritime trade winds. In DJF and MAM the period of the dry dusty Harmatan seasons, surface ozone concentration in the southern Nigeria exceeded that of the north by 21DU and 24DU respectively. Whereas in the JJA and SON,...
