The paper presents the local voltage control of a power transformer as a function integrated in a numerical protection system. Because of this modern integration, the voltage control takes advantage of all the benefits that the numerical technology brings: flexibility, adaptive capability, access to data base interface, self monitoring abilities, logical and mathematical abilities etc. The main objective of the paper is to propose an adaptive functionality of the voltage control function, depending on the topology of the substation in which it is operating. For a certain topology a specific reference value of the voltage control function is set.

Search engines have become a de facto place to start information acquisition on the Internet. Sabotaging the quality of the results retrieved by search engines can lead users to doubt the search engine provider. Spam websites can serve as means of phishing. This paper shows a spam host detection approach that uses support vector machines(SVM) for classification. We create a parallel version of standard Particle Swarm Optimization(PSO) to determine free parameters of the SVM classifier and apply our proposed model to a content web spamming dataset, WEBSPAM-UK2011. Our implementation of the parallel PSO is constructed on a pool of threads and each thread executes tasks associated to a particle from the swarm. Experiments showed that our proposed model can achieve a higher accuracy than regular SVM and outperforms other classifiers (C4.5, Naive Bayes). Furthermore, parallel version of standard Particle Swam Optimization(PSO) can efficiently select parameters for SVM.

This paper comes as a response to the fact that lately more and more accidents are caused by people who drive while intoxicated. Drunk drivers are not able to manage the wheel and make the most basic movements required when driving. This often puts their life and other traffic participants' lives in peril. The proposed system, four alcohol sensors based, can determine if and who has been drinking (the driver or one of the passengers) and it will signal visual and auditive warnings.

Unmanned aerial vehicles are increasingly being used and showing their advantages in many domains. However, their application to railway systems is very little studied. In this paper, we focus on controlling an AR.Drone UAV in order to follow the railway track. The method developed relies on vision-based detection and tracking of the vanishing point of the railway tracks, overhead lines, and other related lines in the image, coupled with a controller that adjusts the yaw so as to keep the vanishing point in the center of the image. Simulation results illustrate that the method is effective, and are complemented by vanishing-point tracking results on real images.

The basic goals of this paper target on the development and implementation of algorithms which provide the energy-minimizing snakes in parametric form, then in applying them to textural analysis based medical diagnosis. In order to derive these algorithms, we focus on Finite Differences Methods (Explicit and Crank-Nicolson Finite Difference Schemes), widely used in medical image processing applications. We examine the consistency, stability, and convergence rate, proving their increased quality able to provide maximum accuracy when determining the diseased anatomic tissue delimitation in the context of medical images.

The paper deals with the implementation of two controllers for the administration of neuromuscular blockade agents in general anaesthesia: Proportional-Integral-Derivative (PID) and Extended Prediction Self-Adaptive Control (EPSAC). Predictive control requires prior knowledge of system dynamics, therefore a mathematical model is required. A Wiener model has been initially identified, using real data recorded during surgical interventions. The controllers were applied to 8 simulated patients and performance was analyzed and discussed for reference tracking and inter-patient variability.

Students are often encouraged to work in groups to solve complex tasks and develop collaboration skills. Classical grouping strategies don't take into account the student's personality or the compatibilities of group members. We introduce an alternative grouping method based on the student typologies and their neuro-linguistic programming (NLP) profile. Typologies are determined, according to the Enneagram methodology, based on the RHETI test. The result of such a test is a chief feature (base typology). Groups are composed of members with compatible chief features. Compatibilities are determined according to the Enneagram principle. New grouping correlations were introduced based on MBTI types. The NLP profile is evaluated by an eye-tracking system, based on eye movement patterns. The proposed grouping method was tested using an e-learning environment, which consists of a CMS (Content Management System) and an eye-tracking component. Eye tracking is based on a low-cost solution that uses a regular webcam. Groups created using this method show an increased communication among the members and better practical results. The tests were realized considering Bachelor and Master of Science students in different educational and practical work activities.

The purpose of this paper is to analyze the behavior of the human tibio-tarsal joint during static loading. The tibio-tarsal joint represents the transition area between the verticality of the calf and the foot. Along with the subtalar and transverse tarsal joints, it represents a crucial component of the ankle. A Finite Element Model (FEM) of the human tibia, fibula and talus was created, taking into consideration the anatomical characteristics of an average weight male adult. In order to analyze the behavior of the tibio-tarsal joint during static loading, the fore mentioned components were rendered in vertical position, and the relations between components were defined. The biomechanical properties (Young's Modulus, Density and Poisson's Ratio) of the human cortical bone were applied with regard to current literature and research. The resulting assembly was subjected to a uniformly distributed pressure of 0,625 kg/cm2. Displacement, vonMisses Stress and Strain were the selected output parameters. The software used to obtain the respective results was SolidWorks® 2014. Understanding the biomechanical behavior of the tibio-tarsal joint during static as well as dynamic loading is essential in order to formulate objective treatment solutions in case of ankle trauma and fracture.

This paper has an informal character. It is referring to distributed parameter processes whose analogical modeling and numerical simulation can be complex and laborious. In these cases, the following compromise can present a major interest: - the determination of some approximating solutions, relatively simple, but sufficiently close to the phenomena reality and on this base: - the elaboration of some analogical modeling and numerical simulation methods with a sufficiently unitary and systemized character based on partial differential equations and after case, with ordinary differential equations, too. In this case, it is proposed a) The analogical modeling through the method of the Matrix of Partial Derivatives of the State Vector (Mpdx); b) The numerical simulation through the (Mpdx) method associated with Taylor series and approximating solutions. This method was used with good results, in numerous examples, in isotope separations processes, thermo-energetics, chemistry, metallurgy, etc. [1-11].

Distillation columns are the main operation units in cryogenic air separation plants that supply purified gasses to a number of industries, one of them being the ammonia synthesis process. The need of an efficient control for the distillation process emerged due to high operating costs: great amount of energy consumption. A proper mathematical model of the column can be used to understand the behavior of the column, predict future reaction and most important to develop a control structure. This paper reviews the conventional models for distillation columns and presents a non-conventional model of the cryogenic air distillation column. Some possible simulation schemes are also presented for column behavior evaluation.
