Performance evaluation of LOS and NLOS vertical inhomogeneous links in underwater visible light communications
(IEEE, 2018-03-22)
In this paper, underwater visible light communication (UWVLC) vertical links are modeled and evaluated, taking account of the inhomogeneous nature of underwater (UW) environment. An equivalent simplified model of stratified ...
Agile performance indicators for team performance evaluation in a corporate environment
(The ACM Digital Library, 2018)
Software development is a must for almost all industries including services, production, health and even construction. Being so widespread, software development industry needs metrics for especially two reasons; performance ...
The design of a high gain dual-polarized quad-ridged circular horn antenna for wideband EMC test applications
(The Applied Computational Electromagnetics Society, 2018-09)
This paper presents the design of a high gain broadband quadruple-ridged circular horn antenna for Electromagnetic Compatibility (EMC) testing. The proposed antenna contains a wideband feed structure as a transition between ...

(Hacettepe University, 2018)
This article reports a mixed-method study that examined the washback effect from a locally-produced, theme-based, high-stakes English language proficiency test in tertiary education in a Turkish EAP context. The aim was ...
Intergenerational mobility and the effects of parental education, time investment, and income on children’s educational attainment
(Federal Reserve Bank of St.Louis, 2018-07-15)
This article analyzes the mechanisms through which parents’ and children’s education are linked. It estimates the causal effect of parental education, parental time with children, and parental income during early childhood ...
A stability analysis for the acceleration-based robust position control of robot manipulators via disturbance observer
(IEEE, 2018-10)
This paper proposes a new nonlinear stability analysis for the acceleration-based robust position control of robot manipulators by using disturbance observer (DOb). It is shown that if the nominal inertia matrix is properly ...
A comparison study on observer-based force control of series elastic actuators
(IEEE, 2018)
This paper presents a comparison study for the robust force control of series elastic actuators (SEAs). In most robotics systems, SEAs are used as an essential actuation method due to the benefits such as lower reflected ...
