Egg Shell Powder Added Rigid Polyurethane Foams: the Investigation of Their Thermal Conductivity, Compressive Strength and Fire Behaviors
(Turkish Soc Thermal Sciences Technology, 2018)In this study, rigid polyurethane foam composites (SPKK's) containing egg shell powder (YKT) with different ratio were synthesized. YKT was characterized by using X-ray difractometer (XRD), X-ray fluorescence spectrometer ... -
Effect of reactive organobentonite additives to the some performance properties of rigid polyurethane foam
(Gazi University, Fac Engineering Architecture, 2017)In this study, bentonite was modified with the compounds which have amine and hydroxyl functionality and obtained organobentonites were used as additive for the synthesis of rigid polyurethane foam nanocomposites (SPKN). ... -

(2017)Regresyon modelleri; birçok açıklayıcı değişkenin önemini ortaya koyabilmek için tahmin, sınıflama, ve analitik veri araçlarını kullanarak, veri analizinde etkili bir rol oynamaktadır. Oldukça basit olmasına rağmen klasik ... -
Comparison of Some Estimation Methods of the two parameter Weibull Distribution for Unusual
(2016)Since the Weibull distribution has been accepted reference distribution in wind energy field, topics on its parameter estimation methods get much attention. In this context, the literature have generally focused on non-robust ... -
The role of the government in enhancing sustainable entrepreneurships
(Inderscience Enterprises Ltd., 2019)The goal of this paper is to point out the role of government in fostering the framework for sustainable entrepreneurship, with special emphasis on the public policy instruments supporting this scope and provide evidence ... -
Algorithms for the spatial median
(Springer International Publishing, 2015)The spatial median can be defined as the unique minimum of a strictly convex objective function. Hence, its computation through an iterative algorithm ought to be straightforward. The simplest algorithm is the steepest ... -
Spatial analysis of unemployment rate with literacy rate and socioeconomic development index for cities of Turkey
(International Business Information Management Association, IBIMA, 2015)The objective of the study is to investigate the spatial pattern of unemployment rate with socio economic development index (SDI) and literacy rate for 81 cities of Turkey and also the spatial correlation between these ... -
Estimation of clearness index model via CRS, TPRS and mars
(2011)Nonparametric approach is more flexible than parametric approach in assuming that f belongs to a smooth family of functions. Hence, a nonparametric approach does not require an assumption of linearity. Based on our motivating ... -
A simulation study with different number of observation using nonparametric regression splines
(2011)In this study we made a simulation study using various nonparametric techniques. The methods that we have used in this study are following: regression spline, penalized spline, and their Bayesian versions: adaptive Bayesian ... -
Robust 2k factorial designs: Non-normal symmetric distributions
(2012)Şenoglu (2005, 2007a) considered the estimation and hypothesis testing procedures for the 2k factorial designs when the error distributions are skew. They obtained the modified maximum likelihood (MML) estimators of the ... -
The relationship between environment and income: Regression spline approach
(2013)This paper examines the relationship between economic growth and carbon dioxide (CO2) emissions, the dominant contributor to the greenhouse effect, in Turkey. For time series data for the period 1980-2009 taking into account ... -
Robust estimation with the skew t2 distribution
(2013)In this paper, a skew extension of the Student's t distribution with two degrees of freedom is used to model data sets that have skewness and heavy-tails. Its parameters are estimated using two different approaches based ... -
M-estimation of log-logistic distribution parameters with outliers
(DAV College, 2014)Log-logistic distribution is widely-used in the analysis of agricultural, survival, hydrological and economics data. Therefore, its parameters have to be estimated accurately. Generally, traditional estimators such as ... -
The individuals control charts for burr distributed and Weibull distributed data
(2006)Constructing the control limits supposes the assumption of the normality. However, there are numerous studies on the control charts when the underlying distribution is non-normal. Several authors have investigated the ... -
