The restoration of regular paper fragments can be solved by edge matching. Edge matching is based primarily on the length and location of the break in writing, however, it is possible that the edges of some regular paper fragments are blank. And so the error of restoration is the inevitable. In this case, it needs manual intervention based on the article content and then eliminate errors. Prior to the establishment of a mathematical model, there is a need for binarization of regular paper fragments with Matlab, then establish vector space model and construct edge contrast matrix, get the order after the Q cluster analysis of fragments. Finally the original picturecan be obtained through splicing and restoring in the order.

The contribution deals with the possibilities of the use of existing commercially available vectorization programs for recognition drawing entities in raster graphics format obtained by scanning of the engineering drawing. Drawing entities as a line (solid, dashed, dot-dashed etc.), dimension, hatch, various symbols, text, etc., have specific semantic for the designer defined by standards. Expert knows to interpret this graphic language and he knows to create a mental model of the real object. To be able interpret digital content of the engineering drawing obtained by scanning by the form of 3D computer model often requires to perform many intelligent operations. In the first step it is necessary to obtain such vector representation of the scanned drawing to be able to identify the original drawing entities. Suitability of using the contemporary commercial vectorizing programs for engineering drawings was verified on the test sample of the drawing entities and the results are published in the paper.

Most of the scientific research engines utilize the same way to rank scientific research papers (SRP), this way is highly depend on the citation network. The retrieved results of these engines for any keyword contain old papers with the highest citation value. In this paper, we proposed a new and easy to implement ranking algorithm for scientific research papers known as Paper Time Ranking Algorithm (PTRA). PTRA is a new ranking algorithm that depends on three factors to rank its results; paper age, citation index and publication venue. To construct and prove our ranking algorithm we created a web crawler that crawl different scientific search papers databases in the world to collect the information that PTRA needs. Unfortunately, some of this information was missing, such as, the impact factor of the journals. To collect this information, we created another crawler that search the Internet for these journals impact factors. However, to prove our ranking algorithm results, we have compared PTRA with Google scholar ranking algorithm. We used Google scholar, since it has more than 50 million papers and its own system can gather and collect papers in a faster way. Our comparison results show that, citation index has the highest impact on Google scholars ranking algorithm results. Unlike PTRA that gains the paper age a higher impact on the ranked results. However, PTRA depends on the citation index and publication venue to rank the results but with less impact than the paper age.

An increasing number of companies establish energy management systems for continuous improvement in their energy efficiency and for this intensify monitoring their current energy consumption. These data can be used to gain further information about the production and to find potentials to increase its energy efficiency. In the procurement process of machinery and equipment or in the planning phase of production systems and building services, information about energy demand is rarely available, though it would be valuable for an early inclusion of energy efficiency in these processes. Therefore this paper discusses different forecast methods for energy consumption of machinery and evaluates in particular their universal applicability, effort and accuracy by analyzing them through the example of a packaging machine. In addition this paper proposes a further usage of energy-related data of machinery, which can be automatically acquired by monitoring systems for prognosticating their energy consumption as well as a possible distribution approach of this information. Therefore an own forecast method is presented, which shall process the energy-related data combined with information about dominant parameters of the product, the usage of the machine and the environmental conditions. For the distribution concept it was taken into account that the generated and shared information has to be abstracted in a way that no critical secrets of the company are revealed.

The present paper describes the activities carried out at Chieti-Pescara University after the 2009 L'Aquila Earthquake. The activities are multidisciplinary and have involved both engineers (structural and industrial) and architects (urban planner and specialist in historical buildings). The goal was to obtain a comprehensive approach to old towns reconstruction. This activity is particularly important to minimize the earthquake consequences.Two peculiar aspects of the work are selected among other ones and presented within this paper. The first one is: how reliable are speedy in-situ surveys, in order to evaluate post-earthquake damages and building occupancy? Considering that both people safety and reconstruction funding depend on this judgment, it is important to check the procedure reliability. The second aspect is the analysis of an old urban center, viewed as a system of fragile components. System components are both material (e.g. a particular building) and immaterial (e.g. availability of the road system), and have been selected to maximize inhabitants safety, above all in terms of first aid to injured people and in terms of efficiency of strategic structures and infrastructures. These considerations are being slowly introduced in the Seismic Italian Code.

The effectiveness of egress paths from a building could be attributed to good signage or intuitive Architecture but we know it is also influenced by human behaviour in fire. The extent to which human behaviour plays a role in the effectiveness of egress routes is not yet fully understood.The aim of this paper is to investigate human behaviour in a relatively simple study of exit choice. The study is conducted in a virtual environment by examining the effectiveness of additional floor-based chevron arrows when compared with conventional exit signage on the same escape routes.Fifty nine participants were asked to interact with the software to escape from a fire in the created virtual environment. Thirty two of the participants used a model with conventional exit signs only. Twenty seven of the participants used the model with exit signs and chevrons on the floor. After completing the virtual egress exercise the participants were given a questionnaire to help understand their behaviour during the task. This allowed the authors to compare results of the post experiment questionnaire with the video output of the test.This research is novel in that involves the use of already existing technologies for new purposes; in this case, commercial computer games engines, generally used for entertainment purposes. As technology reaches new levels it is inevitable that there will be overlap in functionality.This paper describes the experiments, analyses the information gleaned from the research and provides some conclusions for consideration by others in this field. By assessing exit choice behaviour and evacuation time it is possible to compare the effectiveness of the additional floor based signage as a fire protection measure provided above and beyond normal code requirements.

In this paper, we present a new knowledge push technology for complex mechatronic products design based on ontology and variable precision rough set (VPRS).

The inverted pendulum system is a challenging control problem in the control theory, which continually moves away from a stable state. The paper presents the design of a Proportional-Integral-Derivative (PID) controller for a single-input multi-output (SIMO) inverted pendulum system and using the Bees Algorithm (BA) to obtain optimal gains for PID controllers. The Bees Algorithm optimizes the gains so that the controller can move the cart to a desired position with the minimum amount of the change in the pendulum’s angle from the vertically upright position during the movement. The tuning aim is to minimize the control responses of the cart’s position and the pendulum’s angle in time domain. MATLAB/Simulink simulation has been performed to demonstrate that the effects on the system performance of PID controllers with optimal gains. The obtained results show that the tuning method by using the Bees Algorithm produced PID controllers successfully within the controller design criteria. Following a description of the inverted pendulum system and the Bees Algorithm, the paper gives the obtained simulation results for the system demonstrating the efficiency of the design.

This paper presents a new approach for designing the Power System Stabilizer. As in power system network, low frequency oscillation always occurs for a long period of time that will decrease the power transfer capability. Power System Stabilizer known as PSS is being installed as one of the control devices in a generating unit. The conventional PSS (CPSS) is the most commonly used in power system, which uses lead-lag compensation. The lack in CPSS has drawn an interest of designing the new approach of PSS to outperform the conventional one. Thus, Bees Algorithm (BA) which is known as one of the numerous intelligent optimization methods is proposed in this paper. It is appears to aid the system stability by optimizing the PSS parameters tuning. The PSS with the BA approach is labelled as BA-PSS and being tested on single machine infinite bus system (SMIB) in Matlab/Simulink environment. BA-PSS performance is compared with CPSS as to validate the ability of the proposed method to achieve great performance in power system stability enhancement. Different type of mechanical input is being injected into the system and the result shows that BA-PSS is capable to optimize the parameters tuning of PSS. BA-PSS also improved the unstable or poorly stable modes as the system achieve the stability with lower overshoot and less time settling. The superior response of BA-PSS controller proved the ability of BA approach in which is capable to solve the lack in CPSS with better performance in enhancing the system stability.
