Zeroability patterns of monomials in the sign-representation of boolean functions
(2017-06)
Boolean functions (BF) are one of the fundamental concepts in discrete mathematics. It is possible to represent any BF by a unique polynomial when one takes -1 as True and 1 as False. Coefficients of the polynomial ...
Tool support for model based software product line testing
(2018-01)
We introduce a tool for automated adaptation of test models to be reused for a prod uct family. Test models are specified in the form of hierarchical Markov chains. They represent possible usage behavior regarding the ...
Transportation planning for the relief items distribution during an emergency
(2017-01)
We study the inventory slack routing problem (ISRP) to improve planning of distribution of the relief supplies, which is a critical issue in emergency preparedness and response. The authority officials construct their ...
A mathematical model for customer lifetime value based offer management
(2018-01)
Customers with prepaid lines possess higher attrition risk compared to postpaid customers since prepaid customers do not sign long-term obligatory contracts and may churn anytime. For this reason, mobile operators have to ...
Basic psychological needs in relationships with parents and teachers: links to academic motivation, self-efficacy, and performance in mathematics
(2017-01)
The propose of the current study was to examine the relations between the perceived gratification of basic psychological needs (autonomy, relatedness, and competence) in relationships with parents and mathematics teacher, ...
An approach for building information modeling and simulation integrated look-ahead planning
(2018-01)
Look-ahead planning has a key role for construction management as an intermediary between master schedules and site production. Its effective implementation can improve construction management and production control for a ...
Design of high gain wideband quad-ridged horn antenna for emc testing
(2017-06)
This thesis presents a design and simulation of high gain wideband quad-ridged circular horn antenna for Electromagnetic Compatibility (EMC) testing. The selected operating frequency range of the antenna is from 1 GHz to ...
Towards automatic selection of direct vs. iterative solvers for cloud-based finite element analysis
(Civil-Comp, 2015)
The new trend in engineering is to solve complex computational problems in the cloud using high performance computing (HPC) services provided by different vendors. In this paper, we compare performances of direct vs. ...
Realtime healthcare services via nested complex event processing technology
(The ACM Digital Library, 2012)
Complex Event Processing (CEP) over event streams has become increasingly important for real-time applications ranging from healthcare to supply chain management. In such applications, arbitrarily complex sequence patterns ...
Smart job scheduling for high-performance cloud computing services
(Civil-comp, 2011-01)
In this paper, we describe the challenges faced and lessons learned while establishing a large-scale high performance cloud computing service that enables online mechanical structural analysis and many other scientific ...
