Increasing demand in energy facilitated the need of clean energy such as wind energy. Residences, buildings
and commercial sites needs more power, but also continuous power. Important facilities such as wireless or radio sets
requires small amount of energy, but with a continuous supply. This project was done to design and construct a vertical
axis wind turbine for small scale use. After an introduction about the historical background of wind turbine, the report
deals with a more accurate analysis of the main type of vertical axis wind turbine, showing their characteristics,
advantages and disadvantages, differences between vertical axis wind turbine and horizontal axis wind turbine and their
operations. The parameter of the wind turbines was discussed and the generators (stator) that can be used to connect the
wind mill to the electricity grid are reported as well. Several statistics are also presented, in order to explain how the
development of the wind energy in Nigeria. Results from trials shows that as the speed increases, there is increase in
voltage and this in turn implies a watt change at different speeds. This also implies that when there is high wind, there is
a higher rpm. The turbine fulfilled all specifications such as efficiency above 80%, 33Watt output power and likewise the
capacity is adequate for its purpose and was proven to be efficient in generation of current.

Managerial Issues and Implications When Constructing Underground High Level Radioactive Waste Storage Facilities in the UK
Page Numbers : 73-88
DOI : 10.21276/sjeat.2017.2.2.2
This is a research paper focused on assessing experienced project managers/senior engineer’s perceptions of
managing various project issues relating to a proposed underground radioactive waste storage DGF project in the UK.
This empirical inquiry utilised an interpretive perspective. The scope for this research were project managers/senior
engineers who were registered Chartered Engineers and experienced in managing deep civil engineering projects. The
discrete population for this study was made up of individual managers/senior engineer’s (19) presently located on
multiple, independent sites, and a total of 11 managers/senior engineers were determined as the resultant sample frame.
The outcomes consisted of six (6) main themes, namely: Managerial, Technical Capability, Process, Costs, Project
Administration, and Environmental Issues; and twenty (20) sub-themes raised from a literature embedded question. Very
little management research, if any, has been conducted in this extremely provocative area and the paper exposes profound
concerns relating to aspects of the management, which is academically unexplored in today’s demanding international
nuclear civil engineering environment.

The Importance of Multimedia in Information Revolution
Abdulhameed Jastaniyah, Professor Christian Bach
Page Numbers : 89-99
DOI : 10.21276/sjeat.2017.2.2.3
This paper describes the crucial role of Multimedia in our lives, one of the most important new technologies
that we use daily. This paper explains the role and the effect of using Multimedia in education, business and learning.
Consequently, this paper is evaluated and developed by using articles, online journals and primary data collection tools
for gathering valuable information about the importance of Multimedia. In modern world, technological advancement
leads to discover the powerful application of Multimedia. Internet and Social media have significant contribution to
improve Multimedia. As the unstructured data in form of images and pictures are increasing at a rapid speed, Multimedia
is helpful to convert the data into information. This paper is going to help people to expand their knowledge and
information about Multimedia and its strong influences on business and education. The paper shows how technological
innovation can be used by external stakeholders to direct and promote innovation in business.

Modeling and Simulation of Lac Operon Regulation of E. coli bacterium Using Intelligent Fuzzy System
Raed I. Hamed

DOI : 10.21276/sjeat.2017.2.2.4
Current methodologies in displaying dynamic organic frameworks regularly need fathomability, particularly
for users without scientific foundation. In this paper propose another way to deal with defeat such confinements by
joining the graphical representation gave by the utilization of Petri nets with the demonstrating of flow by effective yet
natural fuzzy logic based frameworks. We build a fuzzy reasoning Petri net (FRPN) model for the genetic regulatory
network of the lac operon of E. coli bacterium. Depending on the FPN formalism is a decent other option to
mathematical equations that require dynamic parameter qualities and better than Boolean Formalism which naturally sets
control as "on" or "off" guidelines. The lac operon has been considered as a model framework for comprehension the
molecular biology of gene expression with considered to its regulation. We approve our formal model via programmed
checking a progression of characteristics that are known for the control of the lactose. In this way, we demonstrate the
feasibility of utilizing FRPN to design and reason about biochemical systems.

An Improved E-Learning System
Bello Alhaji Buhari, Abubakar Roko
Page Numbers : 114-118
DOI : 10.21276/sjeat.2017.2.2.5
This research deals with the design and implementation of an improved e-learning system taking Computer
Science Unit, Mathematics Department of Usmanu Danfodiyo University, Sokoto as the case study. It allows upload of
learning materials online and give room for one-on-one interaction with the lecturer by creating an avenue for the
students to ask questions and get their answers online. The system is aimed at being user-friendly, reliable and improved
with better specifications. The e-learning system is designed using HTML, CSS, PHP, Ajax, and MySQL. To ensure
proper interaction between students and lecturers, this proposed system incorporate audio calls to lecturers through Skype
and also video conferencing through webinar (Web Based Seminar); a software that enables lecturers deliver lecture live.
It gives the system the ability to give, receive, and discuss information in real time.

Parshall flume provides economical and flexible water measurement capabilities for a wide variety of open
channel flow situations. The advantages of this structure include minimal head loss, low construction cost, adaptability to
a variety of channel types and ability to measure wide ranges of flow with custom-designed structure. In this study, head
measurements of a stream behind mass communication department, Nnamdi Azikiwe, University were taken using a
fabricated 6-inch Parshall flume for five days. The flow rate of the stream was computed with a Parshall flume equation.
The results achieved shows that the model has good ability to estimate flow rate passing through the fabricated Parshall.
When compared with the free flow calibration table for Parshall flumes, the two results were in good agreement. Flow
rates computed by the fabricated 0.1524m Parshall flume have a slight difference of 0.00002m3/s – 0.00018m3/s, with
that of the free flow calibration. The average error in the estimation of flow rate between them was 0.0032 (0.32%) with
a head loss of 0.0348m.
