Abstract
Macro-fiber composites (MFC) using the 0.23PbZrO3-0.36PbTiO3-0.41Pb(Ni1/3Nb2/3)O3 (PZ-PT-PNN) ceramic were fabricated for aeroelastic flutter energy harvesters. The microstructure of the MFC driven in a transversal mode was analyzed and the performance of a cantilever array consisting of five MFC cantilevers was demonstrated to harvest fluttering energy against the wind. The Ag-coated PZ-PT-PNN ceramic with good piezoelectric properties of d
33 (703 pC N–
1) and k
p (67.7%) was laminated by an approximately 107 um thick film for the completion of the MFC sandwiched between Cu interdigitated-electrode patterned polyimide films. The MFC was enhanced by attaching it onto an elastic substrate (SUS304) for better strain energy transformed from wind energy. It was shown that excellent energy harvesting performance of 0.14 mW cm−3 under 100 kΩ could be obtained at a wind speed of 10 m s−1, implying high potential for use in aeroelastic flutter harvester applications.

Abstract
The close relationship between the nature of the Triangulum–Andromeda (TriAnd) overdensity and the Galactic disk has become increasingly evident in recent years. However, the chemical pattern of this overdensity (R
GC = 20–30 kpc) is unique and differs from what we know of the local disk. In this study, we analyze the chemical abundances of five α elements (Mg, O, Si, Ca, and Ti) in a sample of stars belonging to the TriAnd overdensity, including stars with [Fe/H] < −1.2, to investigate the evolution of the α elements with metallicity. High-resolution spectra from Gemini North with GRACES were analyzed. Overall, the TriAnd population presents an α-element pattern that differs from that of the local disk; the TriAnd stars fall in between the local disk and the dwarf galaxies in the [X/Fe] versus [Fe/H] plane. The high [Mg/Fe] ratios obtained for the lower metallicity TriAnd stars may indicate a roughly parallel sequence to the Milky Way local disk at lower values of [Fe/H], revealing a knee shifted toward lower metallicities for the TriAnd population. Similar behavior is also exhibited in the [Ca/Fe] and [Si/Fe] ratios. However, for O and Ti the behavior of the [X/Fe] ratios shows a slight decay with decreasing metallicity. Our results reinforce the TriAnd overdensity as a unique stellar population of the Milky Way, with an abundance pattern that is different from all stellar populations studied to date. The complete understanding of the complex TriAnd population will require high-resolution spectroscopic observations of a larger sample of TriAnd stars.

Abstract
The presence of asymptotic giant branch (AGB) stars in clusters provides key constraints for stellar models, as has been demonstrated with historical data from the Magellanic Clouds. In this work, we look for candidate AGB stars in M31 star clusters from the Panchromatic Hubble Andromeda Treasury survey. Our photometric criteria selects stars brighter than the tip of the red giant branch, which includes the bulk of the thermally pulsing AGB stars as well as early-AGB stars and other luminous cool giants expected in young stellar populations (e.g., massive red supergiants, and intermediate-mass red helium-burning stars). The AGB stars can be differentiated, a posteriori, using the ages already estimated for our cluster sample. 937 candidates are found within the cluster aperture radii, half (∼450) of which are very likely cluster members. Cross-matching with additional databases reveals two carbon stars and 10 secure variables among them. The field-corrected age distribution reveals the presence of young supergiants peaking at ages smaller than 108 yr, followed by a long tail of AGB stars extending up to the oldest possible ages. This long tail reveals the general decrease in the numbers of AGB stars from initial values of

at 108 yr down to

at 1010 yr. Theoretical models of near-solar metallicity reproduce this general trend, although with localized discrepancies over some age intervals, whose origin is not yet identified. The entire catalog is released together with finding charts to facilitate follow-up studies.
Modeling the Survival of Population III Stars to the Present Day
Authors: Dutta Jayanta , Sur Sharanya , Stacy Athena , Bagla Jasjeet Singh 
Published: September 2020

Abstract
Recent numerical simulations have suggested the probability of a fraction of the primordial stars being ejected from the cluster of their origin. We explore the possibility that some of these can remain on the main sequence until the present epoch. We develop a semianalytical model guided by results of cosmological simulations to study the mass accretion by these protostars as a function of the original stellar mass and other parameters such as angular momentum and gravitational drag due to ambient gas. We also explore whether some of the protostars remain sufficiently low mass and long-lived to survive to the present day. This requires that the protostars are ejected from the star-forming region while their mass is less than

. Assuming that the protostars gain mass via the spherical Bondi–Hoyle accretion from the ambient medium, we show that Population III protostars that initially form within a certain range of mass and are ejected with velocity larger than the escape velocity may survive to the present day on the main sequence. Thus, they may even be found in our Milky Way or its satellites. Our calculations also reveal that protostars that do not get ejected from the parent gas clump accrete a large amount of gas. We predict that these can become massive enough to be progenitors of black holes.
A Deep Search for Stable Venus Co-orbital Asteroids: Limits on the Population
Authors: Pokorný Petr , Kuchner Marc J. , Sheppard Scott S. 
Published: September 2020

Abstract
A stable population of objects co-orbiting with Venus was recently hypothesized in order to explain the existence of Venus’s co-orbital dust ring. We conducted a five days twilight survey for these objects with the Cerro-Tololo Inter-American Observatory 4 m telescope covering about 35 unique square degrees to 21 mag in the r band. Our survey provides the most stringent limit so far on the number of Venus co-orbital asteroids; it was capable of detecting 5% of the entire population of those asteroids brighter than 21 mag. We estimate an upper limit on the number of co-orbital asteroids brighter than 21 mag (approximately 400–900 m in diameter depending on the asteroid albedo) to be

. Previous studies estimated the mass of the observed dust ring co-orbiting with Venus to be equivalent to an asteroid with a 2 km diameter ground to dust. Our survey estimates <6 asteroids larger than 2 km. This implies the following possibilities: that Venus co-orbitals are nonreflective at the observed phase angles, have a very low albedo (<1%), or that the Venus co-orbital dust ring has a source other than asteroids co-orbiting Venus. We discuss this result, and as an aid to future searches, we provide predictions for the spatial, visual magnitude, and number density distributions of stable Venus co-orbitals based on the dynamics of the region and magnitude estimates for various asteroid types.

Data mining, which has different uses such as text mining and web mining, is especially used for clustering and classification purposes. In this study, this method was used for both classification and text mining. The aim of the study was the assessment of the performances of the data mining algorithms on the three datasets. A total of 6631 master's and doctoral dissertations written in the field of industrial engineering were downloaded from the Higher Education Council database. With the help of summary, subject titles and keywords of these dissertations, it was tried to be guessed which sub-field of industrial engineering it belongs to using WEKA program. As a result, it was observed that the data set containing the keywords obtained by weighting the expert opinion was more successful than the other two data sets. And the three most successful classification algorithms were found to be kNN, SMO, and J48, respectively.

Published: September 2020

The study examined the influence of service quality on preference for mobile telecommunication (GSM) service providers among students of tertiary institutions in Lagos State. Specifically, the study determined the influence of service assurance on preference for GSM service provider and assessed the influence of service empathy on preference for GSM service providers among students of tertiary institutions in Lagos State. Findings from the study revealed that service assurance positively and significantly influenced preference for mobile telecommunication (GSM) service providers among students of tertiary institutions (Adj. R2 = .008, F (8,1051) = 2.110, p <.05). Also, findings from the study indicated that empathy positively and significantly influenced preference for mobile telecommunication (GSM) service providers among students of tertiary institutions (Adj. R2 = .008, F (8, 1051) = 2.110, p <.05). The study concluded that increased service quality led to increased preference for GSM service providers among students of tertiary institutions in Lagos State. Thus, an increase in service quality led to an increase in preference for GSM service providers among students of tertiary institutions in Lagos State. Therefore GSM service providers should improve on service assurance and service empathy to enhance consumers’ preference.

Published: September 2020

The study computes the availability of street lighting system in Warri. This system under study consists of subsystems that are known as workstations. A generator and sets of street light make up a workstation. The power source and the street lighting were modeled into series and parallel combinations. Reliability Block Diagrams and Path Tracing Method were employed assuming independent failure of the components. The availability of the set of street lightings, workstations and hence the availability of the system were determined. Results of the study show that users in Cemetery road had the least availability of 62.19% for the period. The implication is that users travelling along this road experienced wide variation of light that could lead to accidents.

Oil spill identification in visible sensor imaging using automated cross correlation with crude oil image filters
Authors: Ofualagba G. , Onyishi D.U. 
Published: September 2020

An algorithm for detection of crude oil spills in visible light images has been developed and tested on 50 documented crude oil spill images from Shell Petroleum Development Company (SPDC) Nigeria. A set of three 25 x 25 pixels crude oil filters, with unique red, green, and blue (RGB) colour values, homogeneity, and power spectrum density (PSD) features were cross-correlated with the documented spill images. The final crude oil spill Region of Interest (ROI) was determined by grouping interconnected pixels based on their proximity, and only selecting ROIs with an area greater than 5,000 pixels. The crude oil filter cross correlation algorithm demonstrated a sensitivity of 84% with a False Positive per Image (FPI) of 0.82. Future work includes volume estimation of detected spills using crude oil filters, and utilizing this information in the recommendation of appropriate spill clean-up and remediation procedures for the detected spills.

Authors: Mohammed H. , Oyebode I.A. , Oyefeso B. D. 
Published: September 2020

Vehicular traffic at Obafemi Awolowo University has increased over the years, resulting in delay at The Main Gate – Ede Road Intersection. This paper evaluated its present level of service with a view to addressing this situation. Geometric survey of the intersection was carried out. Peak hour traffic studies were conducted for a week and the traffic characteristics and volume were determined using standard procedure. The level of service (LOS) of the intersection was thereafter obtained. The geometrics of the intersection showed that, two lanes exist on the East Bound (EB) and West Bound (WB) approaches, as well as a dual lane on the North Bound (NB) and South Bound (SB) approaches. The traffic volume count was 1378, 931, 1168 and 1123 veh/h for the NB, SB, EB and WB respectively. The level of service at the intersection is B, thus implying that it exhibits a slight delay.

Derivation and optimization of deflection equations for tapered cantilever beams using the finite element method
Authors: Ufe M.M. , Apebo S.N. , Iorliam A.Y. 
Published: September 2020

This study derived analytical solutions for the deflection of a rectangular cross sectional uniformly tapered cantilever beam with varying configurations of width and breadth acting under an end point load. The deflection equations were derived using a numerical analysis method known as the finite element method. The verification of these analytical solutions was done by deterministic optimisation of the equations using the ModelCenter reliability analysis software and the Abaqus finite element modelling and optimisation software. The results obtained show that the best element type for the finite element analysis of a tapered cantilever beam acting under an end point load is the C3D20RH (A 20-node quadratic brick, hybrid element with linear pressure and reduced integration) beam element; it predicted an end displacement of 0.05035 m for the tapered width, constant height cantilever beam which was the closest value to the analytical optimum of 0.05352 m. The little difference in the deflection value accounted for the numerical error which is inevitably present in the analyses of structural systems. It is recommended that detailed and accurate numerical analysis be adopted in the design of complex structural systems in order to ascertain the degree of uncertainty in design.

Properties of cellulose reinforced composites: A review
Authors: Ofem M.I. , Ene E.B. , Ubi P.A. , Odey S.O. , Fakorede D.O. 
Published: September 2020

This paper provides a review of cellulose, sources, extraction, molecular structure, cellulose whiskers, preparations, and morphology. The mechanical and thermal properties of cellulose reinforced composites are also discussed. Detail structure of Nano whiskers is also reported. As a renewable biomaterial, the most common source of cellulose is the plant. These plants include fruit fibers (coir), seed fibers (cotton), wood, leaf fibers (sisal), bast fibers (jute, kenaf, and hemp). Other sources of cellulose are from micro-organisms such as fungi, tunicates, bacteria, and algae. Cellulose whiskers are isolated from cellulose fibers by acid hydrolysis. Cellulose micro fibril structures are made of both amorphous and crystalline regions. The amorphous regions are vulnerable to hydrolysis by acids compared to the crystalline domains. Several techniques among which are Field Emission Scanning Electron Microscopy (FESEM), Transmission electron microscopy (TEM) and Atomic Force Microscopy (AFM) have been used to study the morphology of cellulose whiskers. An interface between cellulose whisker and matrix is a transition zone between the matrix and the cellulose whiskers. It plays an important role in the overall mechanical properties of the composites. A soft interface domain will yield a greater resistance to fracture, while the composite will be low in stiffness and strength. On the other hand, a stiffer interface domain may cause the composite to be strong and stiff and less resistant to fracture. The addition of CW into polymers matrices has little or no effect on the glass transition temperature, (Tg) except on the modification of CW.

Oil palm empty fruit bunch ash stabilized laterite as a fill material for low-volume pavement
Authors: Oke J.A. , Obaji N.O. , Osinubi K.J. 
Published: September 2020

A reddish-brown laterite was treated with up to 14 % oil palm empty fruit bunch ash (EFBA) by dry weight of soil and compacted with the British Standard light, BSL (or Standard Proctor) compactive effort. Index, compaction, strength and durability tests as well as microanalysis of the natural and stabilized specimens were carried out. The index, compaction characteristics (maximum dry density, MDD and optimum moisture content, OMC) and strength properties (California bearing ratio, CBR and unconfined compressive strength, UCS) were improved with higher EFBA treatment. Peak un-soaked and soaked CBR values of 70.0 and 45.0 %, as well as peak UCS strengths of 253.0, 462.0 and 577 kN/m2 at 7, 14 and 28 days curing were recorded at 8 % EFBA content. Based on the CBR specification specified in the Nigerian General Specifications, the laterite optimally treated with 8 % EFBA compacted with the BSL compactive effort can be used as a fill material in the construction of low-volume traffic pavement. The benefit of the EFBA application is primarily the reduction of the adverse environmental impact of the oil palm empty fruit bunch waste.
