Advanced Non-linear Mathematical Model for the Prediction of the Activity of a Putative Anticancer Agent in Human-to-mouse Cancer Xenografts
(2020)Background/Aim: Mathematical models have long been considered as important tools in cancer biology and therapy. Herein, we present an advanced non-linear mathematical model that can predict accurately the effect of an ... -
Agent placement in wireless embedded systems: Memory space and energy optimizations
(2010)Embedded applications can be structured in terms of mobile agents that are flexibly installed on available nodes. In wireless systems, such nodes typically have limited battery and memory resources; therefore it is important ... -
Algorithms for optimization of building design: A review
(2014)Building design is quite a complicated task with the design team trying to counterbalance various antagonistic parameters, which in turn are subject to various constraints. Due to this complexity, performance simulation ... -
Ant colony optimization and data mining: Techniques and trends
(2010)The Ant Colony Optimization (ACO) technique was inspired by the ants' behaviour throughout their exploration for food. The use of this technique has been very successful for several problems. Besides, Data Mining (DM) has ... -
Application of Fuzzy Cognitive Maps to water demand prediction
(2015)This article is focused on the issue of learning of Fuzzy Cognitive Maps designed to model and predict time series. The multi-step supervised-learning based-on-gradient methods as well as population-based learning, with ... -
Assessing multiple-group diagnostic problems with multi-dimensional receiver operating characteristic surfaces: Application to proton MR Spectroscopy (MRS) in HIV-related neurological injury
(2008)We present the multi-dimensional Receiver Operating Characteristic (ROC) surface, a plot of the true classification rates of tests based on levels of biological markers, for multi-group discrimination, as an extension of ... -
An automated blastomere identification method for the evaluation of day 2 embryos during IVF/ICSI treatments
(2018)Purpose Evaluation of human embryos is one of the most important challenges in vitro fertilization (IVF) programs. The morphology and the morphokinetic parameters of the early cleaving embryo are of critical clinical ... -
Automated detection of streaks in dermoscopy images
(2015)In this paper we present a novel algorithm for the detection of dark linear structures, which appear in digital dermoscopy images of skin lesions and they are called as streaks in relevant literature. The proposed algorithm ... -
Bayesian uncertainty quantification of turbulence models based on high-order adjoint
(2015)The uncertainties in the parameters of turbulence models employed in computational fluid dynamics simulations are quantified using the Bayesian inference framework and analytical approximations. The posterior distribution ... -
Biological-inspired algorithms for dynamic search in web graphs
(2011)We propose a biological-inspired algorithmic procedure for improving the precision level in respect to a web user's query. This algorithm is capable of tracing relevant information in web graphs, imitating the mission of ... -
Black hole search and exploration in unoriented tori with synchronous scattered finite automata
(2012)We consider the problem of locating a black hole in a synchronous, anonymous, and unoriented torus network using mobile agents. A black hole is a harmful network node that destroys any agent visiting it without leaving any ... -
Broadcast erasure channel with feedback-capacity and algorithms
(2009)We consider the two-user broadcast erasure channel where feedback in the form of ack messages is fed back to the transmitter. We provide an upper bound to the capacity region of this system. We then present two algorithms ... -
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 we create a valid treatment algorithm for patients with drug resistant overactive bladder (OAB) syndrome or detrusor overactivity (DO)? Results from a think tank (ICI-RS 2015)
(2017)Aims: To review and assess the definitions of drug resistance and the evidence supporting treatment for drug resistant overactive bladder/detrusor overactivity (OAB/DO). Methods: Evidence review of the extant literature ... -
Capacity-achieving encoding for the broadcast erasure channel with multiple users
(2011)We consider the N-user memoryless broadcast erasure channel with N unicast sessions (one for each user) where receiver feedback is sent to the transmitter in the form of ACK/NACK messages. We first provide a generic outer ... -
A chance-constrained based stochastic dynamic traffic assignment model: Analysis, formulation and solution algorithms
(2006)This paper is concerned with the system optimum-dynamic traffic assignment (SO-DTA) problem when the time-dependent demands are random variables with known probability distributions. The model is a stochastic extension of ... -
Childhood chronic cough made easy: a simplified approach for the primary care setting
(2021)Cough is a defense mechanism, but when it becomes persistent and troublesome, it must be carefully assessed. Chronic cough, that is, cough persisting for more than 4 weeks, has a proven negative impact on a child's quality ... -
Classification of dermatological images using advanced clustering techniques
(2010)Computer vision-based diagnosis systems have been widely used in dermatology, aiming at the early detection of skin cancer and more specifically the recognition of malignant melanoma tumor. This paper proposes a novel ... -
Column generation for scheduling shipments within a supply chain network with the minimum number of vehicles
(2014)We consider the problem of scheduling a set of shipments between different nodes of a supply chain network. Each shipment has a fixed departure time, as well as an origin and a destination node, which, combined, determine ... -
A comparable study employing weka clustering/classification algorithms for web page classification
(2011)Documents and web pages share many similarities. Thus classification methods used in documents can be applied to advanced web content, with or even without modifications. Algorithms for document and web classification are ...
