Derivative usage by listed companies in Ghana and Nigeria - 2008/2009 [PDF]

, 2011
This study seeks to establish if companies use derivatives and if so what kinds of derivatives. It does not seek to establish the reasons for derivative usage as is commonly done in Wharton Survey Style ...

Riemann–Liouville Type Fractional Derivatives and Equivalences of Linear Riemann–Liouville Type Fractional Differential Equations

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT The first or higher order Riemann–Liouville (R‐L) type fractional derivatives are studied. The relations between the R‐L type fractional derivatives and the classical R‐L fractional derivatives are obtained and the spaces of functions on which the R‐L type fractional derivatives exist are provided.

Positive solutions for boundary-value problems of nonlinear fractional differential equations

Electronic Journal of Differential Equations, 2006
In this paper, we consider the existence and multiplicity of positive solutions for the nonlinear fractional differential equation boundary-value problem $$displaylines{ mathbf{D}_{0+}^alpha u(t)=f(t,u(t)),quad ...

Risk management by structured derivative product companies [PDF]

In the early 1990s, some U.S. securities firms and foreign banks began creating subsidiary vehicles--known as structured derivative product companies (DPCs)--whose special risk management approaches enabled them to obtain triple-A credit ratings with the

Viscoelastic Modeling of Stress Relaxation in Model High‐Performance Covalent Adaptable Networks

Journal of Polymer Science, EarlyView.
Covalent adaptable networks, often referred to as vitrimers, contain a certain fraction of bonds that are able to exchange with other bonds. The ability of this bond exchange to relax stress or result in flow of the material depends on the concentration and specific concentration of these bonds in ways that can be quantified.

Sliding Mode Control in Aerospace Applications: A Survey

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

Embedding Sustainability Commitments in the Strategic Plans of European Higher Education Institutions

Sustainable Development, EarlyView.
ABSTRACT This study analyses how European universities embed the Sustainable Development Goals (SDGs) into their strategic planning, proposing an integrative and multistakeholder measurement tool—Strategizer Scoring System (SDG‐3S). The research combines the Delphi method, content analysis of 198 strategic plans from universities in 33 European ...

Enabling Sustainability in Local Food Supply Chains: A Life Cycle Assessment‐Based Approach

Sustainable Development, EarlyView.
ABSTRACT In response to escalating environmental and food security challenges, this study explores how Local Food Systems (LFS) and Short Food Supply Chains (SFSCs) can be redesigned to support sustainability goals. Drawing on a case study of a microalgae‐based food producer, the research applies a Resource Nexus Approach combined with Life Cycle ...
