The discovery of the adobe materials' original compositions belonging to Ulucak Höyük Neolithic settlement has vital importance to better understand and sustain the historical adobe technology developed in Anatolia. A comprehensive research was done on the compositional and raw material properties of adobe materials belonging to the Early and Late Neolithic periods of Ulucak Höyük settlement. The clay+silt composition, clay+silt ratio, aggregate ratio, organic matter ratio, and particle size distribution of some adobe brick, adobe block, interior plaster, and floor mortar samples were analyzed. Depending on their functions, Ulucak Höyük Neolithic adobe brick/block, floor mortar, and interior plasters differ in their unit weight, clay+silt ratio, and particle size distribution of aggregates. Mainly, (i) the use of proper soil containing mica-illite or mica-illite-kaolin types of clays in adobe mixtures, (ii) clay+silt compositions containing clay sized CaCO3 in varying proportions, and (iii) presence of coarse aggregates in the aggregate compositions, indicate that adobe products of Ulucak Höyük Neolithic settlement are qualified building materials. This qualified adobe technology existing in both the early and late Neolithic layers of Ulucak Höyük signals that this knowledge has survived for centuries. Achieved data is guiding for the production of new adobe materials that can be used in conservation studies. That knowledge is useful not only for conservation studies but also for the development of today's adobe materials and construction technologies.

Frame finite element model for nonlinear and vibration analysis of steel structures with Beam-Column and Column-Base Semi-Rigid Connections Kiriş-Kolon ve Kolon-Taban Yari-Rijit baǧlantili çelik yapilarin doǧrusal olmayan ve titreşim analizleri için çerçeve sonlu elemani modeli

© 2022 Gazi Universitesi Muhendislik-Mimarlik. All rights reserved.In this paper, a shear deformable force-based frame finite element with semi-rigid connections is derived for nonlinear analysis of steel structures. Distributed plasticity approach is defined along element length and section depth, and linear or non-linear semi-rigid connection behavior can be specified anywhere along elements without the necessity to define additional nodes and to increase the degrees of freedom of the structural system.

© 2022 Gazi Universitesi Muhendislik-Mimarlik. All rights reserved.Structural optimization of equipment mounted to payload carried externally by jet type fighter are performed by using the loads: artificial neural network (ANN) prediction, experimental and military specification. The main scope of this study is to evaluate the structural response limits proposed by military specifications with real test conditions and also compare the effects of usage ANN predicted and military specification loads in design...
Unpredictable Solutions of Impulsive Quasi-Linear Systems
Akhmet, Marat; Tleubergenova, Madina; Nugayeva, Zakhira (2022-01-01)
© 2022. L&H Scientific Publishing, LLC. All Rights Reserved.The impulsive differential equations with unpredictable perturbations are under investigation. The definition of the discontinuous unpredictable function with the discrete unpredictable set of discontinuity moments is introduced. The existence and uniqueness of asymptotically stable discontinuous unpredictable solutions for quasi linear systems are proved. Examples with simulations are given to illustrate the results.

Bıçaksız, P.; Doğruyol, B.; Erdost, B.G.; Hoe, C.H.; Gupta, S.; Lajunen, T.; Özkan, Türker (2019-04-01)
© 2019, Gioacchino Onorati Editore. All rights reserved.Speeding is an important risk factor of road traffic crashes, and identifying the factors associated with speeding is crucial for road safety. In the present study, face-to-face roadside interviews were conducted to investigate the reasons of speeding among Turkish drivers at six different data collection times in two different cities. A structured interview was administered to collect data from a total of 3317 and 1559 drivers in Ankara and Afyon citi...
Gaze Aversion In Conversational Settings: An Investigation Based On Mock Job Interview

© 2021. Journal of Eye Movement Research All Rights Reserved.We report the results of an empirical study on gaze aversion during dyadic human-to-human conversation in an interview setting. To address various methodological challenges in assessing gaze-to-face contact, we followed an approach where the experiment was conducted twice, each time with a different set of interviewees. In one of them the interviewer’s gaze was tracked with an eye tracker, and in the other the interviewee’s gaze was tracked. The g...
