The recent Diplomatic Conference held (1-5 October 2001) by the International Maritime Organization (IMO) in London adopted the Draft Convention prepared by The Marine Environmental Protection Committee (MEPC) of IMO for the "Control of Harmful Anti-fouling Systems for Ships." The convention has been developed to immediately ban the use of Tributyltin (TBT) globally in anti-fouling paints to "p...

Orthogonal waveform design is one of the key technologies that affects detection performance MIMO radars. Most existing methods indirectly tackle this problem as an intractable nonconvex optimization and NP-hard problem. In work, we propose a novel algorithm based on intelligent ions motion (IMO) to directly obtain set polyphase codes with good orthogonality. The autocorrelation sidelobe cross-...

This study analyzed the determinants of the productivity of smallholder arable crop farmers with a particular focus on land fragmentation using the Simpson Index as measures of land fragmentation in Imo state of Nigeria. Data collected by using structured questionnaire and interview schedules were analyzed using simple descriptive statistics; Simpson index and regression analysis. Results showe...
