Number of design gyrations for 100 mm compacted asphalt mixtures modified with polypropylene
(Journal of Engineering Research, 2018)There is no standard accepted by highway authorities on the compaction procedures of 100 mm diameter gyratory compactor specimens. In previous studies on gyratory compaction, the utilisation of either coring from 150 mm ... -
OFDM with hybrid number and Index modulation
(IEEE Access, 2020)A novel transmission scheme is introduced for efficient data transmission by conveying additional information bits through jointly changing the index and number of active subcarriers within each orthogonal frequency division ... -
On conformal curves in 2-dimensional de sitter space
(Advances in Applied Clifford Algebras, 2016)In this paper, we examine the pseudo-spherical curves, which are equivalent to each other under the conformal maps preserving a fixed point in the de Sitter 2-space, by using the Clifford algebra Cl 2,1. Also, we find the ... -
On Einstein Finsler metrics
(World Scientific Publishing Company, 2021)In this paper, we study Finsler metrics expressed in terms of a Riemannian metric, a 1-form, and its norm and find equations with sufficient conditions for such Finsler metrics to become Ricci-flat. Using certain ... -
On focal curves of null Cartan curves
(Turkish Journal of Mathematics, 2017)The focal curve, which is determined as the locus of centers of osculating pseudo-spheres of a null Cartan curve, is investigated in Minkowski (n+2)-space Mn+2. Moreover, a curve called acceleration focal curve of a null ... -
On the eigenvalues and eigenvectors of a lorentzian rotation matrix by using split quaternions
(Advances in Applied Clifford Algebras, 2014)In this paper, we examine eigenvalue problem of a rotation matrix in Minkowski 3 space by using split quaternions. We express the eigenvalues and the eigenvectors of a rotation matrix in term of the coefficients of the ... -
On the seismic collapse capacity of optimally designed steel braced frames
(Engineering with Computers, 2020)The main purpose of this study is to respond to an important question in the field of structural engineering: is the seismic collapse capacity of optimally designed concentrically steel braced frames acceptable or not? The ... -
Optimal procurement and production planning for multi-product multi-stage production under yield uncertainty
(European Journal of Operational Research, 2019)Many products with several types are produced in more than one production stage subject to various potential complications, yield uncertainty being a very costly one. This study investigates the input procurement and ... -
Orthogonal frequency division multiplexing with subcarrier gap modulation
(IEEE 31st PIMRC'20 - Workshop on Waveform Design for Beyond 5G Communications, 2020)A new modulation scheme called orthogonal frequency division multiplexing with subcarrier gap modulation (OFDM-SGM) is proposed. The proposed scheme embeds extra information bits by exploiting the gap between the active ... -
Orthogonal frequency division multiplexing with subcarrier power modulation for doubling the spectral efficiency of 6G and beyond networks
(Transactions on Emerging Telecommunications Technologies, 2020)With the emergence of new applications (eg, extended reality [XR] and haptics), which require to be simultaneously served not just with low latency and sufficient reliability, but also with high spectral efficiency, future ... -
Pareto-optimal MPSA-MGGP: a new gene-annealing model for monthly rainfall forecasting
(Elsevier, 2019)Rainfall is considered the hardest weather variable to forecast, and its cause-effect relationships often cannot be expressed in simple or complex mathematical forms. This study introduces a novel hybrid model to month ... -
Pedestrian violations: reasoned or social reactive? Comparing theory of planned behaviour and prototype willingness model.
(Transportation Research Part F: Traffic Psychology and Behaviour, 2019)Pedestrians hold high responsibility in accidents because of their unsafe traffic behaviors. Pedestrian violations are an important traffic safety problem, especially in low and middle-income countries. The problem would ... -
Performance of mechanical steel bar splices using grouted couplers under uniaxial tension
(Journal of Building Engineering, 2021)In this study, grouted couplers were used to connect steel bars as an alternative approach to the conventional steel bar lapping method. The aim is to avoid bar congestion problems and to reduce the required quantity of ... -
Photo-neutron cross-section calculations of 54,56Fe, 90,91,92,94Zr, 93Nb and 107Ag isotopes with newly obtained giant dipole resonance parameters
(Applied Radiation and Isotopes, 2020)The knowledge of the interaction of photons with matter is of vital importance to investigate fundamental nu- clear physics problems. Giant dipole resonance (GDR) mechanism is dominant up to 30 MeV at photo-absorption ... -
Physical attractiveness and managerial favoritism in the hotel industry: the light and dark side of erotic capital
(Journal of Hospitality and Tourism Management, 2019)Erotic capital is the combination of aesthetic, visual, physical, social, and sexual attractiveness to other members of the society, in particular, to the opposite sex. Despite its importance in the workplace, little is ... -
Predicting clinical outcomes in neuroblastoma with genomic data integration
(Biology Direct, 2018)Background: Neuroblastoma is a heterogeneous disease with diverse clinical outcomes. Current risk group models require improvement as patients within the same risk group can still show variable prognosis. Recently collected ... -
