Tight compact models and comparative analysis for the prize collecting Steiner tree problem
(Elsevier, 2013-03)
We investigate a generalized version of the prize collecting Steiner tree problem (PCSTP), where each node of a given weighted graph is associated with a prize as well as a penalty cost. The problem is to find a tree ...
Enhanced energetic reasoning-based lower bounds for the resource constrained project scheduling problem
(Elsevier, 2012-05)
We present new and effective lower bounds for the resource constrained project scheduling problem. This problem is widely known to be notoriously difficult to solve due to the lack of lower bounds that are both tight and ...
Relaxations and exact solution of the variable sized bin packing problem
(Springer Science+Business Media, 2011-03)
We address a generalization of the classical one-dimensional bin packing problem with unequal bin sizes and costs. We investigate lower bounds for this problem as well as exact algorithms. The main contribution of this ...
Heuristics for the variable sized bin-packing problem
(Elsevier, 2009-10)
We investigate the one-dimensional variable-sized bin-packing problem. This problem requires packing a set of items into a minimum-cost set of bins of unequal sizes and costs. Six optimization-based heuristics for this ...
Study of the underlying event in top quark pair production in pp collisions at 13 TeV
(Springer Nature, 2019-02-07)
Measurements of normalized differential cross sections as functions of the multiplicity and kinematic variables of charged-particle tracks from the underlying event in top quark and antiquark pair production are presented. ...
Does risk matter in CEO compensation contracting? Evidence from US restaurant industry
(Elsevier, 2013-09)
The structure of compensation packages of Chief Executive Officers (CEOs) has been a significant research interest for researchers across various disciplines. In this paper, we examine a unique relationship between CEO ...
Tensor form factors of nucleon in QCD
(Elsevier, 2011-10-25)
We extract the isovector tensor nucleon form factors, which play an important role in understanding the transverse spin structure of the nucleon when related to the quark helicity-flip generalized parton distributions via ...
Perceived supervisor and co-worker support for error management: Impact on perceived psychological safety and service recovery performance
(Elsevier, 2014-08)
The study examined the influence of perceived supervisor and co-worker support for error management on employees' engagement in service recovery performance. Furthermore, the current work examined the mediating role of ...
QCD sum rules for the coupling constants of vector mesons to octet baryons
(Springer Science+Business Media, 2013-05)
The QCD sum rules on the light cone proposed by Wang for the coupling constants of the ρ meson are generalized to the vector mesons ω and φ and all octet baryons, the Λ-hyperon included. A comparison with other results is given.
Development and calibration of a currency trading strategy using global optimization
(Springer Science+Business Media, 2013-06)
We have developed a new financial indicator—called the Interest Rate Differentials Adjusted for Volatility (IRDAV) measure—to assist investors in currency markets. On a monthly basis, we rank currency pairs according to ...
