Highway pavement structures are expected to be adequately strong and durable for their design life which can be
achieved only when the pavements are properly designed, constructed, maintained, and managed. In Ethiopia,
most ...
In the present work, biodiesel was produced from watermelon waste oil by the transesterification process. A
definitive screening design was used to investigate the effect of transesterification parameters such as catalyst ...
The rapidly expanding global energy demand is forcing a release of regulated pollutants into water that is
threatening human health. Among various wastewater remediating processes, electrocoagulation (EC) has scored
a ...
Detail understanding of rainfall-runoff processes is tremendously important for a watershed with variable
streamflow generation. The streamflow of the Meki River fluctuates seasonally causing flooding on surrounding ...
This study explored the prospective of croton macrostachyus leaves as bio-based minerals rich resource found for
metal oxides nano-catalyst synthesis by sol–gel-thermal oxidation method and the seeds as a future lipid-rich ...
Agriculture is one of the issues that no-way runs out to be examined. Since farming is one of the
main sources of livelihood of the pastoral population. Thus, the construction of agrarian data grounded internet of effects ...
As a result of the overabundance of digital data, extracting usable, structured data has
become a challenge. Information extraction techniques were developed to simplify the
process of searching for a relevant query ...
In this study, the structural, electronic, and born-effective charge properties of silicon (Si) doped
were investigated with respect to density functional theory by using the Quantum Espresso
Package. The local density ...
The Fused deposition modeling (FDM) is one of the widely used additive manufacturing
process to produce prototypes as well as functional parts from thermoplastics. However, the
application of FDM is still limited for ...
The switched mode DC-DC converters are nonlinear systems that are commonly used in power
electronic circuits due to their high conversion of efficiency and large output voltage range. Gen erally, they are used in all ...
For many decades, the amount of wireless voice and data communications has grown at an
exponential rate from one generation to other generation. Power domain non-orthogonal
multiple access (NOMA) is one of the promising ...
The construction industry contributes significantly to the economic output of a country.
Great numbers of participants from different specializations make the construction
industry a complicated and unique industry. ...
The incidence rate of colorectal cancer is high worldwide, but the survival rate is
greatly improved by early identication of polyps. Colonoscopy is the gold stan dard procedure for diagnosis and removal of colorectal ...

Active magnetic bearings (AMBs) are a technology that makes flywheel energy storage
systems possible. AMBs are used in energy storage systems to suspend the flywheel
without physical contact and allow the flywheel to ...
There are numerous ways to enhance the mechanical properties of aluminum, but se vere plastic deformation (SPD) processing of materials has drawn a lot of attention in
the research community in recent years because of the ...
This thesis was carried out in Jimma Industrial Park of medium scale shoes factory. The aim with
this thesis is to increase the production line performance accordingly minimize the waiting time.
Production line is often ...
Several welding processes have been developed over time, however welding aluminium alloys
has always been difficult using traditional welding techniques because of its low melting
temperature. In addition to this some ...
A spur gear was the most simple, widely used, and efficient type of gear. They were subjected
to bending fatigue failure. The bending fatigue failures began at or near the tooth root sur face of the gear. Shot peening was ...
