Information security risks caused by difficult to exploit vulnerabilities are often treated with countermeasures as last due to their low likelihood of occurrence and should be given a high priority in security monitoring. In this paper, we propose an evaluation of detected attacks in terms of their difficulty - by assigning them an attacker's skill level. We draw similarities between vulnerability's exploitability score and aim to evaluate intrusion detection system alerts within the same framework. We also present the methodology on attacks from a dataset intended for evaluation of intrusion detection systems.

This study aims to identify third year Psychology students' perceptions on their competences and the importance they place on these competences for a Psychology professional, as well as to explore students' inputs on things the faculty can do in order to improve future Psychology students' professional training. 54 Psychology students took part in this survey, in their last academic term, before final exams. More than half of them assess that they have all the professional and transversal competences developed to a large and very large extent. In students' perception, the most developed is Teamwork competence and the least developed is Designing and conducting psychological interventions. In students' opinion, the first most important competences for Psychologists are: Critical thinking, Usage of the main concepts in Psychology, Designing and conducting a psychological research, Psychological assessment of individuals, groups and organizations, and Interpersonal relationship and communication in professional areas. Students identified three main solutions for the faculty in order to improve professional training of future Psychology students.

This paper presents some basic concepts about what smart home means, why it is necessary to build such a home in the future, but also the available technologies in order to automate different processes. After an extended comparative study, the paper focuses on the less intrusive ones and presents in detail a case study for automation a smart home process. The presented case can be applied to most of the scenarios constituting a base for future references.

Water is one of the most important resources for survival. Nowadays, there is a continuous preoccupation for optimizing the use of water resources. The paper presents the model of a decision support system for the optimization of water consumption, which starts from the definition of different consumer profiles. In the water resource management system, several stakeholders are involved: the supplier, the state authority and the consumer, which are linked by well-defined contractual relationships. Depending on the consumer profile, the supplier may establish different types of contracts that favor responsible water use. The system proposes consumer profile oriented scenarios that reflect the influence of consumer habits on water consumption.

The article proposes a method of comparing a collection of series representing the experimental data characterizing a physical phenomenon with a collection of series representing data archived in a catalog, of the same phenomenon, having in addition to the experimental data collection a number of characteristics for each series included. The goal is to associate each series of the sample collection with a series in the catalogue collection through a “proximity”11The term proximity is put in quotation marks because, for the time being, it is not mathematically defined and will be defined in the course of the article. relationship based on a statistical estimator. Once the “closest” series in the catalogue is determined, for each series in the sample collection, the additional features corresponding to the catalogue series, “closest”, are associated with the series in the sample collection. The described process is one of the steps that attempt to improve a method of identifying physical properties of physical environments or objects.

Usability is an important aspect of IT applications being a priority requirement in online public services. This paper presents the evaluation of the usability of the national house of public pensions portal. The portal evaluation involved four experts who tested the portal based on the usability inspection method. The results of the evaluation highlighted some important usability problems that need to be fixed in order to ease the use of the portal by older people.

This paper presents a device for measuring and maintaining the constant water level in a tank. The device uses a capacity sensor to measure the water level. The sensor has a DC voltage output proportional to the water level in the tank. This voltage can be used in other automation too. The water level, in percentages, is displayed on a vu meter with 8 LEDs. The circuit for maintaining the constant level consists in a comparator with hysteresis. The level of the water is adjustable, using a reference voltage from a potentiometer (marked in percentages). The level of the water is compared with the prescribed level and the difference between them commands the start/stop of the water pump which supplies the tank through a relay. The device is powered by 220V and is isolated from the environment.

Device-to-Device (D2D) communication allow the users in proximity to communicate directly, without relay the data through the Base Station (BS). However, in case the users not in proximity to each other the data have been relaying hop by hop to reach user destination. In the multi-hop network, a number of the intermediate nodes used to deliver the data from source to destination. However, the routing decision in a multi-hop network is a critical issue. in this work, the routing decision is taken by a centralised node for a given cell. this paper review a number of centralised multi-hop routing scheme for D2D communication. several experiments are conducted to evaluate the multi-hop routing scheme (reactive and proactive) under different condition and cases. the simulation results show that the number of nodes has an effect on the number of control message exchanged in the network. Moreover, choosing the routing mode on the BS has an effect on the resource consumption on the Base Station.

Nowadays the diversification of energy production, especially with renewable sources, is one of the objectives of sustainable development and the characterization of their functioning and parameters is the subject of interest of the researchers. For green power plants running on biomass, the amount needed is variable depending on several factors. This article aims to determine a dependence between the input-output parameters of cogeneration plant, namely between the biomass consumption and electrical power generated. Using the data collected in the last 3 years from the first such plant that has been operating in Romania since 2014, an interpolation method and an original ordering of annual values are used to obtain the accurate input-output dependence.

Social work professionals have a very complex and emotionally demanding job: they face a large variety of clients, usually the most vulnerable individuals and social groups, who found themselves in problematic situations or even dramas. This kind of work requires a great adaptability, both in terms of professional tools and personal resources. Social workers can experience stress, negative emotions, lack of energy and motivation, dissatisfaction and even burnout, as consequences of their work. This study aims to identify one common profile on job perceptions (including occupational stressors and burnout symptoms) and needs in professional development of social workers from rural regions of seven European countries (Bulgaria, Greece, Italy, Portugal, Romania, Spain, Slovenia). The sample includes 348 social workers who filled in a questionnaire via email. The main results stress the existence of organizational stressors and the need for continuous professional development.
