Bridging the gap between multi-objective optimization and spatial planning: a new post-processing methodology capturing the optimum allocation of land uses against established transportation infrastructure
(2017)The optimal allocation of multiple land uses constitutes a complex multi-objective optimization problem with unknown feasible objective space and optimal planning alternatives. Despite the effectiveness of evolutionary ... -
Calibration of a growth model for tomato seedlings (TOMSEED) based on heuristic optimisation
(2015)A mechanistic growth model for tomato seedlings cultivated in unheated beds is developed, based on modifications of existing tomato growth models. Photosynthetically active radiation at crop level, air temperature and CO2 ... -
Can genetic algorithms improve trading decisions in financial markets?
(2005)Over the last years, trading systems are widely used for market assessment however parameter optimization of these systems has adopted little concern. This paper, paper provides an answer to the question Can Genetic ... -
Carrier assignment algorithms for OFDM-based multi-carrier wireless networks with channel adaptation
(2008)We study carrier assignment in a single-cell multiuser OFDM multi-carrier system so as to satisfy user rate requirements with minimal resources. Different users experience different quality in different carriers due to ... -
Collaborative migration, coupling and simulation of water resources models through OpenMI
(2010)The present study describes the migration and coupling of a monthly conceptual rainfall runoff model named UTHBAL and a water reservoir operation model called UTHRL into the OpenMI standard. The models have been introduced ... -
Collusion of operators in wireless spectrum markets
(2012)The liberalization of wireless spectrum markets has been envisioned as a method for improving mobile communication services and accommodating the increasing traffic volumes of wireless users. It has been assumed that ... -
Comparative calculation of irrigation networks using Labye's method, the linear programming method and a simplified nonlinear method
(2010)The designating factors in the design of branched irrigation networks are the cost of pipes and the cost of pumping. They both depend directly on the hydraulic pump head. It is mandatory for this reason to calculate the ... -
A Comparison of Feature Selection Techniques for Neural Network Based Load Forecasting
(2019)The performance of neural networks in load forecasting tasks is highly influenced by the selection of the inputs. This selection is either problem specific or is relied on the literature. The scope of the present study is ... -
Comparison of optimal buffer allocation in flow lines under installation buffer, echelon buffer, and CONWIP policies
(2020)We compare the optimal buffer allocation of a manufacturing flow line operating under three different production control policies: installation buffer (IB), echelon buffer (EB), and CONWIP (CW). IB is the conventional ... -
Competition and cooperation in wireless access misbehavior
(2011)With the proliferation of access points and terminals, wireless access misbehavior emerges as important means of protocol misuse, whereby network entities aim at obtaining higher channel share than the one in legitimate ... -
Comprehensive model for upgrading two-lane road network
(2012)Concept: Trough rational approach adapted to the actual condition and needs of national and regional network; a Road Upgrading Management model has been elaborated providing the optimum upgrading strategy in each case. ... -
Contention and traffic load-aware association in IEEE 802.11 WLANs: Algorithms and implementation
(2011)Efficient association of a station with the appropriate access point has always been a challenging problem. The standard approach of considering only the Received Signal Strength, has recently been substituted by more ... -
Continuous replica placement schemes in distributed systems
(2005)The Replica Placement Problem (RPP) aims at creating a set of duplicated data objects across the nodes of a distributed system in order to optimize certain criteria. Typically, RPP formulations fall into two categories: ... -
Control and optimization meet the smart power grid: Scheduling of power demands for optimal energy management
(2012)The smart power grid harnesses information and communication technologies to enhance reliability and enforce sensible use of energy through effective management of demand load. We envision a scenario with real-time ... -
Cooperation and directionality: A co-opdirectional MAC for wireless ad hoc networks
(2007)Advances in cooperative communications and directional antenna design so far have taken place in parallel, if not in isolation from each other. To explore the role they may play in the next generation of wireless networks, ... -
Cross-layer energy-aware topology control through Simulated Annealing for WSNs
(2016)In this paper, we optimize the energy consumption and node placements of a wireless sensor network (WSN) using Simulated Annealing (SA). We propose an energy-aware optimization of the power control, the packet transmission ... -
Daily temperature optimisation in greenhouse by reinforcement learning
(2005)The goal of this study is to show the usefulness of reinforcement learning (RL) to solve a common greenhouse climate optimisation problem. The problem is to minimise the daily heating cost while achieving simultaneously ... -
Day-ahead electricity price forecasting using optimized multiple-regression of relevance vector machines
(2012)In deregulated, auction-based, electricity markets price forecasting is an essential participant tool for developing bidding strategies. In this paper, a day-ahead intelligent forecasting method for electricity prices is ... -
A delay based optimization scheme for peak load reduction in the smart grid
(2012)A measurement campaign based on commodity wireless sensors shows that the majority of thermostatic loads in a user premise are described by periodic pulse waves. The superposition of these loads results to high peak power ... -
