Influence of position dependent effective mass on impurity binding energy and absorption in quantum wells with the Konwent potential
(4.6.2021)
In this work, we perform a theoretical investigation on the effect of position-dependent effective mass on
binding energy and optical absorption coefficient for donor impurities in single and double quantum wells
defined ...
Photoluminescence characteristic of as-grown and thermally annealed nand p-type modulation-doped Ga0.68In0.32NxAs1-x/GaAs quantum well structures
(9.6.2021)
The electronic band structure of n- and p-type modulation-doped Ga0.68In0.32NyAs1-y/GaAs (y=0, 0.9, 1.2, 1.7)
quantum well is calculated using the 10 band k•p model and the finite element method for valance band (VB)
and ...
Investigating and counteracting popularity bias in group recommendations
(Elsevier, 2021)
Popularity bias is an undesirable phenomenon associated with recommendation algorithms where popular items tend to be suggested over long-tail ones, even if the latter would be of reasonable interest for individuals. Such ...
Treating adverse effects of blockbuster bias on beyond-accuracy quality of personalized recommendations
(Elsevier, 2022)
Collaborative filtering recommendation algorithms are vulnerable against the popularity bias, including the most popular items repeatedly into the produced ranked lists. However, the research on popularity bias focuses ...
Optimizing Non-linear Granular Layer Coefficients of a Flexible Pavement for Mechanistic-Empirical Method
(2021)
In recent years, mechanistic-empirical (M-E) design methods are preferred in the design of
flexible pavements instead of empirical methods using equations based on the road
performance tests. However, the calibration of ...
Effect of functional grading on the performance of flexible pavements
(2021)
Fatigue failure is an important type of pavement distress which is considered in the pavement design. In
this study, it is aimed to increase the fatigue strength of the pavement without using any additives. For this
purpose, ...
Novel automatic group identification approaches for group recommendation
(Elsevier, 2021)
Group recommender systems are specialized in suggesting preferable products or services to a group of users rather than an individual by aggregating personal preferences of group members. In such expert systems, the initial ...
An entropy empowered hybridized aggregation technique for group recommender systems
(Elsevier, 15.03.2021)
Group recommender systems aim to suggest appropriate products/services to a group of users rather than individuals. These recommendations rely solely on determining group preferences, which is accomplished by an aggregation ...
Binary multicriteria collaborative filtering
(Scientific and technological research council of turkey, 30.11.2020)
Collaborative filtering is specialized in suggesting appropriate products and services to the users concerning personal characteristics and past preferences without requiring any effort of users. It might be more efficient ...
Effects of nano-sized titanium dioxide powder and ultraviolet light on superficial veins in a rabbit model
(Wroclaw Medical University, 2021)
Background. Titanium dioxide (TiO2) is widely used in many fields such as food, cosmetics, and paper industries. Studies on the photocatalytic properties of TiO2 on living tissue are limited.
Objectives. To examine the ...
