Hybridized Intrusion Detection and Prevention System Using Static IP Address

Oluwasogo Adekunle Okunade
Internet growth and constant increase in traffic volume, resulted into various misuse and attacks on the internet, that increases security challenges over intrusion detection and prevention system against sophisticated attacks. This has become paramount importance since single mode intrusion detection systems have a lot of difficulties in protecting system and network from sophisticated attacks. However, this paper propose hybridized intrusion detection and prevention system using static IP address whereby the incoming packets are examined for...

Proportional Integral Differential (PID) Controller

Abdullahi Tekanyi, Angulu Rakiya & Kabir Abu-Bilal
Piezoelectric ceramics are used in many areas of applications. One of such areas of applications is in controlling electronic devices for accuracy and improved precision. Piezoelectric ceramics however have the problem of inherent high resonance frequency resulting in the piezoelectric ceramic suffering from hysteresis and delay in response to input parameters. PID controllers have been used in providing improved control and response to the piezoelectric ceramic so as to overcome the problem of hysteresis as...

Resurgence of Militancy and the Challenges of Sustainable Peace and Development in the Niger Delta

Oyinlola Abodunrin
The Niger Delta region has been a theatre of conflict especially after the discovery of oil in commercial quantities in the area. One of the reasons responsible for intermittent and simmering conflicts in the area is prolonged hardship experienced by the people in the region due to activities associated with oil exploration and neglect of the region as far as development is concerned. Various governments have proffered different solutions to the crisis but all ended...

The Politics of Foreign Aid: A Study of China-Zambia Economic Relations

Praise A. Ayinla & Sheriff F. Folarin
Sustainable Development Goals (SDGs) adopted globally in September 2015 are set to measure development and progress in countries until 2030. China, second to the United States in the global development agenda, by its relations with Africa and Zambia, particularly in the provision of foreign aid currently plays an important role in the development of Zambia’s economy. The large amount of foreign aid provided by China has led to assertions that Zambia is being put in...

Bleeding the Commonwealth: An Assessment of Odu’a Investment Company Limited, 1985-2008

Abimbola Oyarinu
Corruption is a scourge destroying public enterprises in Nigeria but the idea that corruption is the major reason why public enterprises fail might be far from the truth. Enormous corruption occurred in Odu’a Investment Company Limited between 1992 to 2008, which led to the obliteration of the Yoruba patrimony. While associated companies, which are run by private hands are making profits and paying dividends, the subsidiary companies are being bleed white owing to massive corruption...

Exploring Nigeria’s Potential for Labour Exportation: Lessons from the Republic of Philippines

Maureen Fubara & Sheriff Folarin
The paper examines Nigeria’s potential for labour exportation by assessing the performance of labour exportation in the Republic of Philippines. Imperatively, the trend of international labour migration presently influences the nature of international economic relations between developed and developing nations. Many developing nations have utilized their huge population base to accrue major financial and non-financial gains through labour exportation to developed climes. However, Nigerian is yet to borrow a leaf from nations like the Republic...

Sensitivity Analysis of the Gonorrhea Disease

Akanni John Olajide, Adediipo Adeola David & Akinpelu Foluke O.
In this paper we formulate an SEIR (Susceptible – Exposed - Infective - Recovered) model of Gonorrhea disease transmission with constant recruitment. The threshold parameter R0< 0, known as the Basic Reproduction Number was found. This model has two equilibria, disease-free equilibrium and endemic equilibrium. By constructing suitable Lyapunov function, it was discovered that the disease-free equilibrium is globally asymptotic stable whenever R0 is less than one and when it is greater than one, the...

Magnetohydrodynamics Flow of a Third Grade Fluid Through a Cylindrical Pipe in an Inclined Plane With Radiation

Bolarin, G., Yusuf A., Emmanuel, O. and Aiyesimi, Y. M.
This work considered the natural convection of a one-dimensional heat generation and viscous dissipation model of a Magnetohydrodynamics (MHD) third grade fluid in an inclined cylindrical pipe with radiation. The governing dimensional equations of the momentum and energy were first non-dimensionalized and then solved analytically using the Homotopy Analysis Method (HAM). The results obtained are displayed on graphs. From the graphs, we observe that increase in the grashof number leads to increase in both the...

Emmanuel Ifeduba & Tosin Olatunji
As traditional mass media grapple with hyper-competition globally with the attendant challenges of web-based alternatives and loss of readership and revenue, they are migrating online for survival in line with the contemporary management models. In Nigeria, it is not certain how they are adjusting to these new realities. This study examines the income-generation profiles of online news media in the country within the context of the technological determinism and mediamorphosis theories. Contents from 183 publishers...

An Assessment of the One Lecture-One Test Learning Model by Journalism Teachers

Oladokun Omojola
This article analyzes transcripts from a knowledgeable group that discoursed at length the one lecture - one test (OLOT) learning model – a system that requires students to write a short test for 10 to 20 minutes after every lecture, for a score that counts toward the overall grade. This model contrasts with the traditional system in most higher institutions that set two or three tests and give one or a few assignments in a...
