We implement a visibility-based motion planner for systems in which, because of kinematic constraints, not all maneuvers may be reversible. We use samples that are nonzero dimensional subspaces of the configuration space in an attempt to make the heuristic more efficient at generating large strongly connected components; the non-zero dimensional samples also reduce the computation load associated with validating trajectories. We integrate the resulting planner method with various local planner strategies for kinematically constrained vehicles, and compare the sizes of the roadmaps needed to solve a problem with bug traps for several vehicle models, one of which is reversible and serves as a base-line. Finally, we suggest directions of improvement of the algorithm based on simulation results.

Out of the workflow representations that are excellent to model business processes this paper examines the possibilities of the p-graph-based workflow modeling for administrative activities. Taking the special requirements of document management into account it gives a possible solution for document processing, the more reality like modeling of activities and resources. This paper introduces special descriptors for the various document types, activities and resources. Thus making the p-graph based workflow modeling more applicable for the modeling of administrative processes. Beyond the static examinations the extension of the p-graph-based model enables the analysis of dynamic behavior and the analysis of process executions.

The paper proposes to define three parameters that can be associated with lumbar spine diagnosis. These parameters will further be used in a prediction software that aims to establish a treatment indication in the early stages of the medical exploration. These parameters quantifies very different conditions of the patient: pain - a very subjective parameter; the calories consumed in one day - measurable value; biomechanical parameters like range of motion in lumbar spine and postural angle - measurable parameter. These parameters have to be interconnected and therefore recordings before and after surgery and treatment have to be made. The interconnection of those represents a challenging task that requires a large patient's database from which the statistics can be computed. Another cornerstone in interconnection is the lake of biomechanical statistics on the lumbar spine pathologies.

Many modern smart mobile devices integrate a multitude of various sensors which can enrich the usability of today mobile applications. However, collecting and analyzing data from sensors requires increased processing, storage and energy resources on mobile devices. On the other hand, context-aware mobile applications require an estimation of high-level user context, in order to provide the user with specific services. It is not simple to model and estimate in real-time user context, even though a lot of low-level sensors data are available. Therefore, in this paper we investigate how data collected from different mobile sensors and communication interfaces can be used to extract the user context.

We propose a distributed control lighting system (hereafter, Intelligent Lighting System) for achieving personal illuminance. The Intelligent Lighting System changes the luminances for individual lights based on a self-distribution algorithm. It learns the influence of lights on illuminance sensors through regression analysis and controls the lighting to achieve the required illuminance in the required places. When the numbers of lights and illuminance sensors increase, however, an error in the regression coefficient becomes larger; accordingly, the influence of the lights on illuminance sensors may not be correctly estimated. To solve this problem, this study proposes a method for correcting the results of the learning of the influence of the lights on illuminance sensors by estimating the illuminance sensor positions. With the proposed method, we estimate the illuminance sensor positions and determine the distances between the individual lights and illuminance sensors to correct the results of the learning according to the distances. The method proposed in this study enables the illuminance sensor positions to be estimated with an error of less than 1 m. Moreover, the method makes it possible to appropriately control lighting luminance compared with conventional method, achieving an improvement in illuminance convergence speed as well as a 5% reduction in power consumption.

In this paper we introduce a finite source retrial queueing model to investigate the performance characteristics of the wireless transmission problem in sensor networks. We divide the sensors into two classes. The first one is the “Emergency” class, which performs the notification of special emergency situations (eg. fire alarms). The second one is the “Normal” class, which measures and transmits environmental data (eg. temperature). For the performance evaluation of the wireless transmission we study and compare two cases: In the first model the RF transmission possibility will be available randomly for the sensor nodes (Non Controlled case) and in the second model the RF transmission requests coming from the emergency class, will access the wireless channel immediately (Controlled case). Our main interest is to give the main steady-state performance measures of the system computed by the help of the MOSEL tool.

In the digital age, the possibilities which Information and Communication Technology (ICT) gives offer numerous advantages to contemporary society. The full exploitation of the latent teaching and learning potential which lies within us all depends solely on the individual's receptivity, attitude and available digital capabilities. This article acquaints the reader with some of the pedagogic challenges, possibilities, and practices in the digital domain which might be of assistance in improving the efficiency and success of both teaching and learning.

Traditional education systems are highly theoretical and almost entirely based on student knowledge memorization. Nowadays european society development is focused on practical skills, globalization and competitiveness. Existing romanian e-learning systems tend to present and explain knowledge in a spectacular way using multimedia but none of them are based on the concept of competence. The solution in this sense is a new educational system which is based on competencies achieved in real life scenarios.
