Analysis of fabric behaviour during wearing has shown that these are submitted to simple and repeated uniaxial or biaxial tensile strains. The level of these strains is often within the elastic limit, rarely going over yielding. Therefore the designer must be able to evaluate the mechanical behaviour of such fabrics in order to control the fabric behaviour in the garment. This evaluation is carried out based on the tensile testing, using certain indexes specific to the stress-strain curve. The paper considers an experimental matrix based on woven fabrics of different yarn counts, different or equal yarn count for warp and weft systems and different structures. The fabrics were tested using a testing machine and the results were then compared in order to determine the fabrics’ tensile behaviour and the factors of influence that affect it.From the point of view of tensile testing, the woven materials having twill weave are preferable because this type of structure is characterised by higher durability and better yarn stability in the fabric. In practice, the woven material must exhibit an optimum behaviour to repeated strains, flexions and abrasions during wearing process. The analysis of fabrics tensile properties studied by investigation of stress-strain diagrams reveals that the main factors influencing the tensile strength are: yarns fineness, technological density of those two systems of yarns and the weaving type.

This paper presents the steps to obtain a statistical model for a technical textile process-the influence of plasma treatment on polypropylene fibres. Plasma treatment of polypropylene fibres on an installation with variable working parameters led to appreciable modifications of fibres' mechanorheological and surface properties. Thus, the paper focuses on highlighting the influence of technical parameters-active power and number of cycles, on the properties of polypropylene fibres and the determination of some factors for its optimisation. The first step of statistical modelling is to obtain data from the textile process through the programmed experiment method. The significance of the regression equation coefficients and the statistical adequacy of the model was analysed. The results obtained by the presented research are highlighted quantitatively and qualitatively throughout the experimental region and can be used in the educational and industrial fields. The current study is practical didactically by explaining the steps of statistical modelling on a textile process with practical applicability in the technical field.

The basic and unitary understanding of these concepts is mainly connected with statistical techniques for the measurement and/or estimation of system's reliability, as well as with predicting techniques from artificial intelligence field. Researches performed until now, based in an overwhelming proportion on statistic methods that imply collecting data sometimes hard to determine and obtain on large time horizons, often prohibited, and with predicted results that need validation, lead to the necessity of a new approach for the calculation of this parameter from the management of safety in operation. The main objective of our research consists in the determination of an alternative techn...

An ever-increasing number of employers use online tools to search and select their employees. Thus, in addition to the traditional job recruitment websites that provide the opportunity for direct recruitment, employers often use "indirect" methods, searching their future employees among candidates - specifically individuals who are present and visible in the online environment or have been recommended by others, who are not actively pursuing a new job at the moment. Aside from searching on social media, blogs, and other links that include the name of the prospective candidate, more and more employers will use, as recruitment method, a Skype interview and/or will request a self-introduction video presentation. Despite being avid users of internet, a signifi...

Neural network modeling enables design engineers in safety of operation to iteratively and interactively test the parameters and evaluate the corresponding changes in system performance before physical realization. For this reason, NN is an efficient tool in designing systems. NN can also be used during system testing as additional tools to determine the optimal operating values of the parameters and to determine their tolerance. The novelty of this paper is the combination into compact algorithm of mathematical and neural techniques in the realization of the correlations of the safety operation parameters and in the optimization of the dependability system in order to support the production-quality strategies. If mathematical modeling is the basis for the optimization operation, providing multivariable functions tha...

That is why one cannot separate the task of providing a reliable operation, from the problems of designing the device, organizing the production and its exploitation. The RO estimation requires objective precise criteria and with this purpose in mind, one resorted to a probabilistic approach of the RO problem applied to a quantitative investigation of the technical systems. This approach resulted from the classical definition of RO, its meaning being the probability of operation within a time interval. Complementary to this definition, one defines another element of RO, namely devices shutdown, characteristic that can be examined as a series of random events. The random character of the breakdown event is related to the insufficient or erroneous ch...

Thus, the organizational implementation of an Environmental management system represents an important “strategic move” which can bring many benefits and could become that “advantage lever” in front of competitors. Therefore the Environmental management system (EMS) implementation and its real integration at the organizational general management level bring along the “routinization” (application in day-to-day organizational activities) of certain environmental practices, which will be the main topic of this work. Having in view the idea mentioned above, the literature presents the fact that organisations mainly adopt two types of attitudes towards the environmental issues (“marginal attitudes types”), as follows: (a) a reactive attitude towards the environment as an effect of the necessity to ...

In this context, the professional competences determine a unitary and dynamic assembly of knowledge and competences that an employer is pursuing from an employee. Most of present approaches consider this concept either from an individual prospective, related to the individuals capability to get a job, or from an organizatory one, which takes into account the motivator climate through which the employers propose to entice and retain good employees. The purpose of this exploratory study is to identify the general professional skills that contribute to increasing the employability of Romanian higher education graduates from the perspective of the employers in the field of engineering. In the analysis of this study we propose a new systemic approach based on a statistic procedure for the optimiz...

Within these problems are found the problems of partitioning graphs with partitions that meet different partitioning criteria. The paper presents a case study for the problem of partitioning graphs - organizing the graph, practical applicability of the problem, partitioning function, method of solving the problem by using three genetic algorithms working individually on islands of problem solutions, changing synchronously with each other solutions, and the application of the algorithm on a numerical example. Finally, the paper proposes conclusions and future directions of development.

The developments in management and performance measurement are trying to address these contemporary challenges of the technological and socioeconomic environment. The social environment in which corporations operate is affected by their actions, but at the same time corporations experience the pressures of society. Production systems represent the tool that translate innovation into finished products and by bring them closer to the customer, support the continuous improvement of quality of life. The paper present a fuzzy expert system based on Balanced Scorecard Model (BSC) used in textile companies to assess the performance indicators for a sustainable market position.

Thus, mathematical techniques combined with artificial intelligence techniques are used to determine the connection and causal relations between the components of the technical systems. Applying mathematical methods hybridized with artificial intelligence techniques requires knowledge of each technical system and their optimal combination. Thus, we design a didactic and practical application methodology, structured gradually on a real data set, with objectives observed and conclusions justified at each analysis stage. This paper complements and was based on scientific papers from the specialized literature in this field, using working hypotheses regarding the distributions of the series of parametric values and the logical relationships of interdependence between the studied parameters. The importance of the paper derives from the theoretical and practical implementation of a unitary statistical based on artificial intelligence algorithms in the field of textile systems maintainability, which will gradually define the relationship between the maintenance parameters. The paper's novelty elements consist of the systematization of the primary data through a programmed experiment and the statistical regression analysis combined with neural and genetic modeling and compare models results.

This research will model a Travelling Salesman Problem (TSP). The complexity of this fundamental problem (np-hard) allows a chance to apply and develop heuristic methods and evolutionary algorithms along with exact methods (dynamic programming, branch & bound). This paper proposes a new discrete algorithm to solve the TSP based on the Particle Swarm Optimization (PSO) technique. The features of this method are fast determination through an iterative process of the optimal problem, the generalised search in all the solutions, and the avoidance of the local optimal. To avoid premature convergence, we have introduced a new operator with a new mathematical function, and we have proposed new techniques for measuring and maintaining population diversity. We tested the algorithm's performance by applying it to numerical instances and compared it to the solutions and performance provided by other evolutionary algorithms. By delaying the convergence process, the new algorithm PSO offers reasonable solutions in terms of quality comparable to those offered by different evolutionary algorithms tested. At the end of the research, we highlighted the conclusions, limitations, and new techniques based on the PSO algorithm.

The paper presents a practical approach about how the gender of students influences the organizational group behaviour with the main objectives to evaluate the organizational behaviour on two groups (M/F) and to create a qualitative and quantitative pattern for organizational behaviour inside formal groups. The authors used the questionnaire of Hellriegel, Slocum and Woodman as an instrument that includes three types of behaviourbehaviour focused on tasks/objectives, behaviour focused on relationships, and behaviour focused on own interests. We used statistical methods-the T testto see the differences between M/F and statistical factorial modelling-PCA method to identify the predominant items to define a new model for organizational behaviour. The necessity of the research comes from the dynamic of behaviour inside a group which involves (individual) internal and external (relations and tasks) essential factors.

The studies undertaken until now have proved the necessity of a new approach of the causal relationship between safety in operation and production strategies, based on mathematical and neuronal modelling. The objective of our research consists in the determination of reliability/ maintainability relationship for a manufacturing process (dependent output variables), and production/resulted quality (independent input variables). In this connection, we propose a unitary software instrument applied to this optimization problem, able to refine qualitatively the results and to combine the algorithmic character of this mathematical approach with the neuronal networks learning based one. In order to reach the prop...

Thus, sustainability represents a comprehensive issue in that it directly apply / integrate synergically this concept at business level (compared to the macro-sustainability plan), focusing in particular on long-term environmental, financial and social performance. In the literature, the issue of organizational sustainability is analyzed extensively, but being at the limit to be confusing on its institutionalization's basics. Consequently, it's very complicated to evaluate and establish actions for organizational sustainability, given the lack of consensus on addressing this issue (indicators, associated dimensions correlations, methods, models, methodologies). The paper main objective is to identify the main components associated to organizational sustainability (dimensions: economic / financial, environmental and social) based on its determinants (using the main components analysis-PCA, and respectively the scores on each component). The results this research will contribute to the completion of scientific knowledge, by combining classical methods of data analysis with advanced one. Thus, starting from a series of empirical evidence and statistically validated causal links, was obtain models with the purpose to evaluate organizational sustainability; approach that could be consider still in the "beginning" in the literature.
