Most of macro- economic variables exhibit cyclical behaviors, state dependency and regime switching and modeling such series using univariate linear time series models fails. This study test for non –linearity and linearity in the behavior of the Naira/US dollar exchange rate where the exchange rate exhibits a regime switching between the year 1970 and 1994 using a non- linear time series class model to describe the structure of the series. For this purpose, a logistic smooth transition regression was detected to fit a yearly data over the sample period 1970 to 2013. There is evidence of non-linearity in the behavior of the series and also evidence of continuous of regimes or allow of smoothing the series as it was revealed from the large value of the smoothing parameter. The model estimated was powerful and eligible in the sense of conformity to economic reality and sounds usefulness for decision makers, forecasters to forecast macro-economic variables that exhibit cyclical behavior through the use of this type non – linear class time series models.

Keywords - Regime switching, Non –linear Time series, Linearity, Non –Linearity, Logistic smooth Transition regression, State Dependency, Cyclic behaviors.

There is a symbiotic relationship between musicians and the media where one depends on the other for survival in the market especially in the broadcasting sector. Musicians need their music to be marketed and promoted by the media and this means that it is necessary to understand the procedures involved. The media are envisaged to play a key role in music marketing and promotion and this role and processes involved must be clearly brought out to the artists. The study sought to explore the role of mainstream media with particular reference to radio in music marketing and promotion. The research was informed by a constructivist philosophy which argues that knowledge and meaning are generated from an interaction between researchers and participants. A qualitative research methodology was employed for the study as it is appropriate when one does not need to manipulate the behavior of those involved in the study............

survey was conducted between March to December 2020 to determine the floristic diversity and taxonomic profile of rupicolous species of Naraguta mountain. Ten (10) plots of (20 m x 20 m) were surveyed at sub-Montane and Montane altitude of the sites. All woody plants with a stem diameter of 3 cm at breast height (DBH) in the plots were identified. Three 1m x 1m quadrat was established in each (20 m x 20 m) for inventory of herbs and grasses. One thousand five hundred and seventy one (1571) plants species distributed in 43 families were encountered. The most abundant families were, Papilionoideae, Rubiaceae, Sapindaceae and caesalpinioideae. Consequently the most occurring families of herbaceous plants occurred in decreasing order were, Asteraceae, Acanthaceae and Malvaceae............

The emergence of COVID-19 across the globe had become a major concern for countries all over the world. Over the years, there had been lots of global health challenges which had threatened the existence of human beings in the world but none had adversely affected education as corona virus did since its outbreak in 2019 in Wuhan, China. Nigeria detected its first case on February, 27th 2020 in Lagos. As of June 13th, 2020 the country tested 92,924 samples and had 15,682 confirmed cases and 407 covid-19 related deaths in 35 of the 36 States in Nigeria and Federal Capital Territory. In order to contain the spread of the virus, on March 30th, 2020, the Federal Government announced a lockdown in FCT, Lagos and Ogun states. Many Governors in other States followed the Federal government initiative...........

Cloud computing is a relatively novel concept that promises among other things an ubiquitous provisioning of both hardware, software and other resources in a metered fashion along with other extra capabilities. However, like the internet, it has certain challenges which are not tractable. For instance, the designer of cloud computing artifact has no way of determining certain network and internet conditions and constraints of the artifact when in operation at design stage to enable efficient control of these resourcesfor effective operation. This calls for an effective means of simulating and evaluation of these cloud artifacts during development stage, so that the behavior will be gauged and predicted at any point of development and use............

With the advent of the Internet we can say that a new industrial revolution has begun. If in the beginning only computers could connect and communicate with each other, the idea of Internet of Things (IoT) or Industrial Internet of Things (IIoT) pushes technological evolution to the next level, making possible the connection to the Internet of all the devices created for this purpose. Industrialization 4.0 is the latest industrial revolution, and is not based on the discovery of a new form of energy, but on the digital world or digitization, due to the continuous development of computers, sensors and the mass generalization of the Internet. This article provides an overview of the minimum requirements for migrating from Industry 3.0 to the first step of the Industry 4.0 concept, by highlighting the possibilities of communication between production and management lines, the advantages brought due to their interconnection and the management of the collected data using a Manufacturing Execution System (MES).

Costs of construction materials in Nigeria tends to be very high and the need to reduce environmental pollution has necessitated research into the use of waste materials, such as agro-industrial waste to replace traditional materials used in concrete production for pavement work. This work gives an account of the study conducted on the comparative of the density, strength and cost of Control Concrete and Palm Kernel Shell Concrete (PKSC) where Palm Kernel Shell (PKS) were used to fully replace crushed granite in the mix. The control concrete and PKSC cube were produced from a selected mix 1:1:2 and water-cement ratio 0.5 and tested according to provision of BS 12390-2 (2000), BS1881-125 and BS EN 12390-3 (2000) and eventually evaluated for road work suitability. Control concrete and PKSC of dimension 1.0............
