The Marching Cubes algorithm is based on the estimate of the isovalue in order to determine all the pixels that are belonging to the volume to be reconstructed. This estimation is done by the user in an interactive and way without any orientation; this is no longer an intuitive process. Solutions are proposed to detect more than one isovalue and have been used to display multiple isosurfaces and not to adjust or automatically determine isovalue. Other solutions propose to explore histogram to estimate isovalue automatically; those remain insufficient because they still require user intervention. The proposed method acts directly in the isovalue estimation phase. In fact, we propose to make this estimate by using automatic methods of sampling, which have shown their performance in estimating a threshold in several works. This paper proposes to make the use of existing automated isovalue selection methods that take into account histogram and the dynamics of the image. The automatic Marching Cubes algorithm reduces user interaction and makes the selection process more intuitive. The obtained results will show that this adaptation minimizes the computing time and that the obtained volumes are of better quality than those obtained by the classical Marching Cubes algorithm.

The purpose of this paper is to implement information security risk management (ISRM) in research information systems (RIS). Appropriate identification and assessment of risks in different aspects such as software, communications, and human resources for RIS{\textquoteright}s besides providing efficient and effective preventive and corrective actions are other aims of this study. Furthermore, continual improvement of risk response processes in information technology environment is another aim of this study.\  In this study, potential risks of information security are identified using failure mode and effects analysis (FMEA). Also, detected failure modes are evaluated by multi-criteria decision-making method (MCDM) using a hybrid method of fuzzy logic, analytic hierarchy process (AHP), Shannon entropy scoring method, and technique for order preference by similarity to the ideal solution (TOPSIS). The result of this paper shows that information security software potential risks assessment by the proposed model is more accurate and reliable than non-fuzzy models. Unauthorized access to view or change the stored information of the server is the risk with the most important priority identified by MCDM approach. Confidentiality of information is more important than other information security criteria. Furthermore, failure modes in the category of the main server and internet have more priority in comparison to others.

The widely dependence on mobility has became nowadays a priority for people. The automotive industry has lately grown impressively a lot. Most of the people give cars an important place in ranking their priorities, and this is the reason of developing an Android application for mobile phone, to help resolve certain car problems, which often occur. This application is divided into three categories that facilitate the elimination of car damages. The first part is composed of symptoms, which users visual or auditory notice (observing a particular engine noise, unusual smoke detection). This part helps the car owner to repair the vehicle with only basic information in this domain. The second part is composed of a Google Map, which shows all the car services in a specific area. This part of the application is dedicated to serious problems of the vehicle, which cannot be detected and which can damage the car. The third part consists of connecting the phone to the onboard computer through a device OBD II ELM-327 Bluetooth that allows certain functions to appear on the mobile screen display (speed, air intake, fuel level). In conclusion, we believe that this application is useful, because it helps to clarify car key issues, contributing in this way also to solving the environmental problems regarding pollution.

Our key idea is based on Multi-Agent Systems (MAS) technique owing to its modularity, autonomy, distributedness, flexibility, and scalability. All agents serve their specific purposes. We use PKI technology to secure both intra- and interdomain agents communication as well as to establish trust relationships. The Security Assertion Markup Language (SAML) is adopted to support the exchange of authentication and authorization information in the architecture. The authorization scheme is based on the Privilege Management Infrastructure (PMI). In addition, we incorporate the XACML authorization concept into the MAS engine to support the relying parties or organizations whose their access control systems are written in XACML policy.

In this paper, we present NEWER, a neuro-fuzzy Web recommendation system that dynamically suggests interesting pages to the current user. NEWER employs a neuro-fuzzy approach in order to determine categories of users sharing similar interests and to extract a recommendation model in the form of fuzzy rules expressing associations between user categories and relevances of pages. the derived model is used by an online recommendation module to dynamically suggest interesting links.

Such sensor-rich environments should be able to offer distributed and dynamic access to resources according to context information, such as user{\textquoteright}s location and time. In this scenario, the access control decisions should be based also on context information. However, as context information represents real-world situations, it is associated with certain quality indicators, such as up-to-dateness and precision, which can directly affect the access control decisions. Furthermore, enforcing user{\textquoteright}s privacy policies on context information can decrease the quality of context (QoC) information used for making access control decisions. Quality of context has in fact a strong impact on the suitable behavior of contextbased access control models. Using context information with inadequate quality may increase the probability of incorrect access control decisions. Therefore, it is important to take into account also the QoC while enforcing context-based access control policies. This paper proposes a Context-Based Access Control Model that takes into account context information and its QoC indicators to grant and to adapt access permissions on resources for Ubiquitous Computing Environments. A new module to evaluate QoC indicators was integrated in our context management architecture that is being used by proposed access control model.

According to our approach, constraints are expressed by using high-level data model, such as OMT-G, and converted in a proper visual language grammar automatically. From such a grammar, a parser able to identify incorrect aggregation of spatial data input is generated. The grammar formalism also allows us to associate suitable semantic actions with productions in order to perform automatic corrections of inconsistent input data, error recognition and visualization, prompting actions for error recovery.
