Hybrid Meta-Heuristics Based Task Scheduling Algorithm for Energy Efficiency in Fog Computing
Get PDFTask scheduling in fog computing is one of the areas where researchers are having challenges as the demand grows for the use of Internet of Things (IoT) to access cloud computing resources. Many resource scheduling and optimization algorithms were used by many researchers in fog computing; some used single techniques while others used combined schemes to achieve dynamic scheduling in fog computing, many optimization techniques are reassessed based on deterministic and meta-heuristics to find out solution to scheduling problem in fog computing. This paper proposes Hybrid Meta-Heuristics Optimization Algorithm (HMOA) for energy efficient task scheduling in fog computing, the study combines Particle Swarm Optimization (PSO) Meta-heuristics and deterministic Spanning Tree (SPT) to achieve task scheduling with the intention of eliminating the drawbacks of the two algorithms when used separately, the PSO is used to schedule user task requests among fog devices, while hybrid MPSO-SPT will be used to perform resource allocation and resource management in the fog computing environment. The study proposed to implement the algorithms using iFogSim in the future work such that performance of the algorithms will be evaluated, assessed and compared with other state of art scheduling and resource management algorithms

Comparative Study of Reinforced Concrete Design Norms (BAEL 91, BS8110 and Eurocode 2) on the Design of a two Span Beam in Cameroon
Get PDFThis research compares the beam longitudinal reinforcement areas required by different international design norms or design provisions that deals with the design of reinforced concrete structures namely the French norms: Bétons Armée aux Etats Limites’ (BAEL) 91 revised in 99, the British standards BS8110 and the Eurocode 2(EC2) as used with the Frech national annex ( NF EN 1992-1) and the British national annex (BS EN 1992-1). The aim of this research was to determine which code or norms provides the most safe and economical design in Cameroon. From the literature, the study first gathered information on the design criteria and beam analysis from the different international norms as well as on the properties of steel reinforcement bars and concrete. The study adopted a continuous beam of 2 spans for the design. Concrete grade 20/25 and 12mm diameter bars were chosen. The yield strength of reinforcing steel, the density of reinforced concrete and the effective depth (d) depended on the requirements of each code. The area of tensile reinforcement obtained by EC2 (both France and Britain National annex) is smaller than that of BAEL 91 and BS8110 at support and at spans as well. This shows that Eurocode 2 results in more economical areas of reinforcement steel bars than when designing with BAEL 91 or BS8110. Since Eurocode 2 results in smaller required steel reinforcement areas, this decreases the steel reinforcing bars congestion in a structural member. The BEAL91 has the highest required steel reinforcement area due to its lower yield strength amongst all the other codes under study. The study recommends that Cameroon should as a matter of urgency draw up her national annex and starts the full implementation of Eurocode 2 in order to enjoy its manifold benefits
Spatial Distribution of Schistosomiasis and its associated risk factors among Preschool aged children in Temeke district, Tanzania
Get PDFSchistosomiasis is a public health problem common in poor communities that causes damage to the urinary tract and intestines among people as well as stunting among young children. Little is known about the prevalence and risk factors for schistosomiasis in pre-schoolers. This study aimed to determine the spatial distribution and geographical and clinical factors associated with schistosomiasis among pre-schoolers in Temeke district. We conducted a secondary data analysis to determine the spatial distribution of schistosomiasis among preschoolers, a hotspot analysis to identify hotspot areas, and visited them to observe geographical factors associated with schistosomiasis. We also conducted key informant interviews (KI) with community members to identify risk factors for schistosomiasis. Univariate and multivariate logistic regression models were used to find associations between dependent and independent variables. We analyzed 226 study participants, of whom 91 (40.27%) had a schistosomiasis infection and 135 (59.73%) had no infection. Of all, 113 (50.0%) of the participants were female, and 113 (50.0%) were male. Most participants lived within 1 km of the river. A total of 79 (34.96%) participants used river water. While 172 (76.11%) of participants used tap water for drinking, 53 (23.45%) used borehole sources for drinking water. In multivariate analysis, stunting and malnutrition were significantly associated with schistosomiasis infection. Spatial analysis identified clusters of schistosomiasis infection more in the northern part of Temeke district and fewer in the south of the district. The findings suggest a need for the establishment of a suitable control strategy for schistosomiasis in Temeke district, which will include all groups at risk, including preschoolers

Architects as Fashion Designers: An Emerging Enterprise for Sustainable Growth
Get PDFABSTRACT Overtime the fashion world in Nigeria has largely depended on imported products. Statistics show that most of these products do not meet the socio-cultural and economic needs of the people. However, efforts made by fashion designers to bridge this gap by rolling out innovative fashion products and adequate skill-sets have suffered setbacks. To sustain this creative industry amidst the economic recession, this research explores the potential of architects - the master designers’ contributions to the fashion enterprise as one that has the potential for significant growth. The research explored the frontiers of fashion design and how architects can get involved to improve processes, products, and services through mixed research methods encircling data collected from literature reviews, interviews, case studies, and observation. The research results reveal that architects can function as fashion designers as 41 out of the 50 respondents constituting 95.3% of the studied population comprised of fashion designers and users were positive that the input of architects in the field of fashion is essentially needed to artfully realize the sustainable growth of the industry, 68% of the respondents strongly agreed that fashion designers share a similar skill set with architects, 44.9% of the respondents and 53.1% agree and strongly agree respectively that architects can become fashion designers, while 95.3% of the respondents are enthusiastic about seeing more architects in the fashion industry. The architects’ richness in artistic skills and creativity encapsulated in their sufficient knowledge of anthropometrics and ergonometric, user preferences, elements and principles of design will bring a significant boost to the fashion industry with new and improved articles of clothing which will, in turn, generate revenue for them, promote the growth of the Nigerian Gross Domestic Product (GDP), propagate the nation’s cultural heritage and tourism, stimulate her global recognition and attention.Keywords: Architect, Creativity, Fashion Design, Emerging Enterprise
