Acrylic Polymers as Additives for Engine Oil: A Historical Perspective
Comment Share
Nasser, Rabab M.

Oil undergoes temporary viscosity changes under operating conditions in engines. Therefore, engine oils usually contain polymeric additives called viscosity modifiers. These additives are oil soluble polymers; enable the oil to provide adequate hydrodynamic lubrication at high temperatures and good starting/pumping performance at low temperatures. P…

Brahimi, Abdelghani

In this chapter, we present our study of geopolymers and hybrid geopolymers synthesized with treated fly ash from eggshells (FAES) and sand from the dunes of southern Algeria using activators such as NaOH and Na2SiO3, respectively, in addition to the organic polymer polyethylene terephthalate (PET). Several parameters have been modified, such as alk…

Comment Share
Mabrouk, El Houssine

We reported here the synthesis of new α,α-diaminoester and α,α-diamino acid derivatives, as 2-benzamido-2-[(tetrahydro-furan-2-ylmethyl)amino] acetic acid through alkaline hydrolysis reaction of corresponding N-benzoylated methyl α,α-diamino ester. The α,α-diaminoester derivative was synthesized by nucleophilic substitution of methyl α-azid…

Modelling of Solar Radiation for Photovoltaic Applications
Comment Share
Afungchui, David

This chapter explores the different ways in which solar radiation (SR) can be quantified for use in photovoltaic applications. Some solar radiation models that incorporate different combinations of parameters are presented. The parameters mostly used include the clearness index (Kt), the sunshine fraction (SF), cloud cover (CC) and air mass (m). Som…

Shah, Wiqar Hussain

The different elements are doping in the tellurium telluride to determine the different properties like electrical and thermal properties of nanoparticles. The chalcogenide nanoparticles can be characteristics by the doping of the different metals which are like the holes. We present the effects of Pb doping on the electrical and thermoelectric prop…

Vector Optimization and Monotone Operators via Convex Duality Recent Advances
Comment Share
GRAD, Sorin-Mihai

This book investigates several duality approaches for vector optimization problems, while also comparing them. Special attention is paid to duality for linear vector optimization problems, for which a vector dual that avoids the shortcomings of the classical ones is proposed. Moreover, the book addresses different efficiency concepts for vector optimization problems. Among the problems that app…

Vector Generalized Linear and Additive Models With an Implementation in R
Comment Share
YEE, Thomas W.

This book presents a greatly enlarged statistical framework compared to generalized linear models (GLMs) with which to approach regression modelling. Comprising of about half-a-dozen major classes of statistical models, and fortified with necessary infrastructure to make the models more fully operable, the framework allows analyses based on many semi-traditional applied statistics models to be …
