Developing a collaborative planning framework for sustainable transportation
(Hindawi Publishing, 2014)
Currently, as being the highest petroleum consuming sector in the world, transportation significantly contributes to the total greenhouse gas emissions in the world. Road transportation not only is responsible for approximately ...
Inventory routing for the last mile delivery of humanitarian relief supplies
(Springer Nature, 2020-09)
Fast and equitable distribution of the humanitarian relief supplies is key to the success of relief operations. Delayed and inequitable deliveries can result in suffering of affected people and loss of lives. In this study, ...
Performance analysis of MIMO free-space optical communication systems with selection combining
(IEEE, 2013)
In this paper, we investigate the outage performance of a multi-input multi-output (MIMO) free-space optical (FSO) communication system with selection combining (SC). Under the assumption of log-normal distributed atmospheric ...
Effective robot skill synthesis via divided control
(IEEE, 2018-07-02)
Learning from demonstration is a powerful method for obtaining task skills, which aim to eliminate the need for explicit robot programming. Classically, the tasks are demonstrated to the robot by means of either recorded ...
Novel channel models for visible light communications
(SPIE, 2015-02-07)
In this paper, we investigate channel modeling for visible light communications (VLC) using non-sequential ray tracing simulation tools. We create three dimensional realistic simulation environments to depict indoor scenarios ...
On the performance of DCO-OFDM visible light communication systems under illumination constraints
(IEEE, 2015)
In this paper, we consider a DC-biased optical-orthogonal frequency division multiplexing (DCO-OFDM) visible light communication system and investigate its error rate performance under illumination constraints. First, we ...
Energetic reasoning revisited: application to parallel machine scheduling
(Springer Science+Business Media, 2008-08)
We consider the problem of minimizing makespan on identical parallel machines subject to release dates and delivery times. We present several new feasibility tests and adjustment techniques that consistently improve ...
An EOQ model with deteriorating items and self-selection constraints
(Springer Nature, 2020-09)
In this paper, we consider a store that sells two vertically differentiated items that might substitute each other. These items do not only differ in quality and price, but they also target two different customer segments. ...
Pilot-aided channel estimation on SC-PAM based visible light communications
(IEEE, 2018-07-02)
Estimation of the time-varying optical wireless channel response is crucial in order to decode received signals coherently. In this work, we investigate symbol-error-rate and mean absolute error performance of different ...
An approach for predicting employee churn by using data mining
(IEEE, 2017)
Employee churn prediction which is closely related to customer churn prediction is a major issue of the companies. Despite the importance of the issue, there is few attention in the literature about. In this study, we ...
