Navigating the complexities of marketing decision-making in uncertain supply chains: A quantitative exploration
Making rational decisions in times of uncertainty is an important capability required of marketing
managers. However, choosing the precise quantitative decision-making technique or a combination
of such tools usually presents managers with a score of challenges. To lessen this challenge,
this single case research demonstrates how the choice of three Bayesian decision models
(Laplace criterion, Savage minimax regret, and Hurwicz coefficient of realization) can reduce
uncertainty in content marketing, search engine optimization (SEO), and referral marketing decision.
We employed the case study approach to enable direct access to the decision-making
process of the case organization, and to collect relevant data relating to the three marketing
decision variables. Results show that, although the Laplace criterion may not have a direct effect
on content marketing decisions, it influences the decision-making process leading to the creation
and promotion of content. The Savage minimax regret had a direct bearing on SEO decisionmaking.
Hurwicz's coefficient of realization yielded no direct impact on referral marketing but
shows the possibility of influencing decision-making processes that led to the development and
implementation of referral marketing campaigns. The implications are discussed

NomadicBTS-2: A Network-in-a-Box with Software-Defined Radio and Web-Based App for Multiband Cellular Communication
The proliferation of mobile communications technologies has greatly contributed to the development of emerging economies.
However, a significant digital divide remains in many remote and hard-to-reach regions due to the high Capital Expenditure (CapEx)
and Operating Expenditure (OPEX) of mobile network operators. This study addresses the issue by developing and prototyping
a cost-effective, software-defined base station, called NomadicBTS-2, utilizing open-source technologies and the Software-Defined
Radio (SDR) paradigm. NomadicBTS-2 incorporates the Universal Software Radio Peripheral (USRP) B200 as the Radio Frequency
(RF) hardware front-end. The software backend is built on open-source solutions, including the USRP Hardware Driver (UHD)
and services such as OpenBTS, Asterisk, SIPAuthserve, and SMQueue. Additionally, a custom web-based software, NomadicBTS
WebApp, was developed to configure and monitor the UHD and software services via a Graphical User Interface (GUI). The system
was tested using two mobile stations (MSs) for simplex and duplex communication, while network link quality parameters were
evaluated to assess users’ Quality of Experience (QoE). Experimental results demonstrated that, within a pico-cell environment, the link
quality is sufficient for call routing and Short Messaging Services (SMS) between user-to-user and network-to-user communications.
NomadicBTS-2 presents a robust solution for a Network-in-a-Box, ideal for short-range communication in rural and hard-to-reach
areas, emergency response scenarios, and IoT sensor networks. It can also be deployed to alleviate network congestion in existing
mobile networks. Furthermore, this prototype offers a viable testbed for teaching and research laboratories to explore advancements
in SDR, cognitive radio, and other wireless communication technologies, thus opening new frontiers in wireless communications researc

Microbial biotechnology for bioenergy: general overviews
Bioenergy technologies are environment-friendly, renewable, and a clean way of
powering the global community. Bioenergy technology is an innovation that improves
the quality of life by simply reducing water and air contamination; this also mitigates
energy dependence through creation of renewable resources locally. Bioenergy sources
include wind, water, geothermal, nuclear power, solar, and natural gases. The most
interesting and important part of bioenergy is the environmental benefits as part of a
global energy future, which are aided by microorganisms. The future of bioenergy,
however, seems bright because recent global information in this field proved that more
renewable energy capacity has been fixed globally than new fossil fuel and nuclear
capacity combined. As the global population progressively increases, there is an everincreasing
demand for clean energy. The only safe answer to this is sustainable energy,
which will protect the earth from climate change and make it a good habitat for all living
organisms. This chapter provides a general overview to microbial biotechnology for
bioenergy, sources, and challenges of bioenergy, role of microorganisms in bioenergy
generation, innovations in bioenergy, and the environmental conservation of bioenergy

Petrophysical analysis to determine the hydrocarbon prospectivity of sands in AA field, Niger Delta
Petrophysical analysis is a crucial process in the oil and gas industry. It entails the analysis and
interpretation of well logs, fluid samples or core smaples to understand the behaviour of the embedded
reservoirs in the subsurface. Three well logs from AA field were provided for this study, but two well data
were finally loaded to the workstation due to absence of key well logs (such as gamma ray and density logs)
from the third well. The quality control check of the data was done prior to the uploading of data. Delineation
of lithologies and identification of hydrocarbon reservoirs were done; the identified reservoirs were
correlated across the two wells; and the petrophysical evaluation (such as estimations of shale volume,
porosity, permeability and water/hydrocarbon saturation) of the three pay zones (that is, Sand A, B and C) in
AA field were done. The porosity of Sands A, B and C varied from 0.27 to 0.28, 0.24 to 0.30 and 0.27. The
permeability of Sands A, B and C varied from 1012 to 1314 md, 884 to 1013 md and 692 to 892 md.
Meanwhile, the hydrocarbon saturation for Sands A, B and C varied from 1 to 89%, 45 to 80% and 79 to
80%, respectively. It can be concluded that the order of hydrocarbon prospectivity of the reservoir sands
correlated across Well AA-1 and Well AA-2 is Sand C > Sand B > Sand A
I-V response test of 60–150W mono-crystalline solar panel
This work investigates the discrepancies in electrical parameters of monocrystalline
solar panels between Ago-Iwoye weather conditions and the
manufacturer’s specified ideal conditions. Manufacturer’s specifications are
typically based on 1,000 W/m2 global solar irradiance, AM 1.5, and 25°C
operating temperature, while actual weather conditions at installation sites
can vary significantly. Mono-crystalline (single-crystal) silicon solar panels of
capacities 60, 80, 100, and 150W were evaluated through current-voltage
(I-V) response tests at an installation site in Ago-Iwoye, Nigeria, with solar
irradiance exposure from 11 a.m. to 3 p.m. The analysis of I-V and P-V curves
revealed a significant reduction in maximum power output by 28.6%, 25.9%,
28.9%, and 19.36%, respectively, compared to the manufacturer’s stated values.
This deviation underscores the importance of considering local weather
conditions during solar PV projects, and we recommend adding an additional
20%–30% of the total solar panel capacity during installations to account for
variations in solar irradiance and operating temperatures, ensuring optimal
performance and effective solar power generation in Ago-Iwoye and
similar areas
