Econometric modeling of the impacts of shipping on Nigeria economy
(Open Access International e-Journal, 2016-01) Nwokedi, T. C.; Okoroji, L. I; Igboanusi, C. C.
The study is conducted to establish a quantitative relationship (model) between the impacts shipping on the economy of Nigeria and the Gross Domestic Product (GDP) using an econometric method and to test the significance of the impact. The econometric/analytical method of regression analysis was adopted to achieve the objective. Time series data of 10 years were collected on the past contributions of maritime transport to the national output (GDP) from the Central Bank of Nigeria annual statistical bulletin. Hypotheses were tested using t-test. The test showed the rejection of null hypothesis HA and the acceptance of null hypothesis HB to conclude that maritime transport has made significant impact on the Nigerian economy over the period covered by the study.
Cabotage implementation in Nigeria: Analysis for improving coastal shipping business opportunities for local and joint venture operators
(Exclusive Journal Publishing House, 2016-01) Nwokedi, Theophilus C.; Igboanusi, Chinemerem C
The year 2013 marked a decade of the implementation of cabotage law in Nigeria. This study analyzed the implementation of the policy over the 10 years period from 2004 to 2013. The aim of the study is to assess how the implementation of the policy has affected indigenous and foreign coastal shipping firms and how to use the policy to increase coastal shipping business opportunities for local ship operators. Data on number of cabotage vessels chartered from local and foreign shipping operators, their charter fees for each year covered the study were obtained. Assuming equal charter rate for cabotage vessels of local and foreign operators chartered in each year covered by the study, the research estimated the earned by each class of operator from charter fees. The difference of means statistical method was used to analyze the data on number of local and foreign ship operators vessels charter over the period and revenue earned from cabotage vessel. T-test was used to test each null hypothesis. Both null hypotheses H0A and H0B were rejected for the alternate hypotheses. The research found that Non-Nigerian (foreign) ship operators have earned more revenue and supplied more vessels to coastal shipping operations in Nigeria. It was recommended that the cabotage policy be amended remove the provision for waiver option to foreign vessel and encourage joint venture arrangement between local and foreign firms.
International trade flow analysis using the gravity model - The Nigerian conondrum
(MNK Publications, 2014) Onyemachi, Chinedum; Igboanusi, Chinemerem C.; Ezenwa, Anthony Ekene
he work surveyed several international trade flow models applied to transportation and spatial interaction analysis. The connectivity between international trade flow, port development and hinterland acquisition were analyzed based on evolving market demands.The relevance of the gravity model both to the international trade and port hinterland analysis were identified. Methods for the estimation of trade flows using natural logarithms applied to the gravity model were developed. Furthermore, the work assessed the rising influence of both hub and dry ports in the world of international trade. While the later is situated in the hinterland, the former is situated at few major world ports. The relevance of the gravity model in determining the location of these port types was emphasized. The strategic roles of rising hub ports to world trade were also discussed. Relevant data were picked from the Nigerian Import and Export environment.
Determination of the optimal routing protocol for an inter-campus private cloud network system
(Federal University of Technology, Owerri, 2023-05) Ezeani, Chukwuemeka Obioma
With the need for resources sharing and the integration of cost-effective IT solution across tertiary institution in Nigeria, modalities for an inter-campus cloud network is presented in this project. The inter-campus cloud network provides a platform for sharing resources across campuses instead of replicating such resources which are in many cases underutilized. This work presents the optimal routing protocol for an inter-campus cloud network system that connects 5 campuses together within Owerri city in Nigeria. A star-star hybrid network topology was adopted in this project work and was modelled using Packet Tracer simulator. The network was simulated using the three main routing protocols namely RIP (routing information protocol), OSPF (open shortest path first) and EIGRP (enhanced interior gateway routing protocol) which were tested and compared to determine the routing protocol with the shortest convergence time. The connection time of the three routing protocols used on the exchange point network was run at a TTL value of 24 and packet size of 32 bytes. The RIP provided a convergence time that is within 3 and 4 seconds, with slightly varied spikes of not up to 10 seconds, OSPF and EIGRP also tries to maintain a time of between 3 and 4 seconds but is plagued with so much spikes of up 20 seconds for EIGRP and 17seconds for OSPF. The results showed that with a routing protocol like RIP, connections between the campuses via the exchange point will converge faster. As a result, RIP routing protocol was adopted as the optimal routing protocol to be used for the network configuration due to its better convergence time.
Optimization of biodiesel development from non-edible indegenous feedstocks in Nigeria
(Conscientia Beam, 2019-08-07) Nwoko, Christopher Ikpe Amadi; Nkwoada, Amarachi Udoka; Ogu, Helen Ugochi
This study investigated the transesterification of Rubber seeds (Hevea brasiliensis), Avocado Pear seeds (Gratissima persea), and Nipa Palm Kennel seeds (Nypa frutican) locally sourced from Nigeria as an adsorbate for the esterification reaction of oleic acid with methanol. Reaction was catalysed by potassium hydroxide (KOH) to form methoxide oleate (biodiesel) adsorption from aqueous solution in batch model for the production of biodiesel. The results obtained showed that rubber seeds oil (RSO), Avocado pear seeds oil (APO) and Nipa palm kernel seed oil (NPKO) oil gave maximum biodiesel yields at 0.9 % w/v, 0.1 % w/v and 0.1 % w/v catalyst concentration respectively. Their biodiesel yields were 88.0 %, 92.0 % and 96.7% respectively. They recovered biodiesel were characterized as an alternative fuel via specific gravity, viscosity, acid value, flash point and cloud point. The results obtained showed that the specific gravity for RSO (0.886 kg/m3), APO (0.876 kg/m3) and NPKO (0.850 kg/m3)were fairly significant at temperature of 25 oC to other conventional petroleum diesel ASTM D 975, standard biodiesel ASTM D975, and standard biodiesel ASTM 6751 and EN14214.
