Authors: Labisz Krzysztof , Tański Tomasz , Krupińska Beata , Krupiński Mariusz , Pakieła Wojciech
Published: October 2014

The purpose of this paper was the investigation of laser treatment influence on the microstructure and properties of the surface layer of heat treated Al-Si-Cu cast aluminium alloys, using the high power diode laser (HPDL). The performed laser treatment involves remelting and feeding of ZrO2 ceramic powder into the aluminium surface. Based on the performed investigations it was possible to obtain the layer consisting of the heat affected zone, transition zone and remelted zone, without cracks and defects as well as has with a slightly higher hardness value compared to the non remelted material. The laser power range was chose as 1.5 to 2.0 kW and implicated by one process speed rate of 0.25 m/min. Also a powder size was used for alloying with the particle size of ca. 100 μm. The hardness value increases according to the laser power used so that the highest power applied gives to highest hardness value in the remelted layer [1-8]. The carried out investigations allow to conclude, that as a result of alloying of the heat-treated cast aluminium alloys with oxide ceramic powder the surface layer can be enriched with the powder particle and in some cases a high-quality top layer is possible to obtain. Very often to determine conditions of laser treatment are being used the numerical methods that would significantly shorten the time to find the most optimal parameters. [8]. Concerning original practical implications of this work there was important to investigate the appliance possibility of High Power Diode Laser (HPDL) for enhancement of the aluminium surface properties, especially the wear resistance and hardness. the scientific reason was also to describe structure changes and processes occurred in the laser remelted surface aluminium layer after ZrO2 feeding using HPDL laser [10-1. .

Published: October 2014

In this paper are presented the results of experimental studies determining the dependence of the impact of an innovative welding micro-jet method on the intensity of abrasive wear of chrome-manganese 20MnCr5. The presented method is generally used for the constructions work items matrix for the production of silicate. The results confirm that the micro-jet welding method reduces the abrasive wear intensity of about 20% compared to the steel after thermo-chemical treatment. Other parameters such as the friction coefficient and power friction show comparable value, and therefore do not have a significant impact on working conditions.

Published: October 2014

This paper shows some possibilities to adjust the exposure time and output power of a given microwave device according to the process to be executed, taking into account the special operating conditions of the magnetrons and the efficiency of the microwave device. Since the exposure time is rather easy to set by means of timers, the microwave power level is difficult to modify because of the magnetron requirements voltage, current, magnetic field which must be carefully observed in order to ensure reliable operation. The research has been carried out at the University of Oradea and INCDTIM Cluj-Napoca, during the activities of the Microwave Collective of the University of Oradea and during the preparation of the doctoral thesis of Mr.Ursu.
On Transient Queue-Size Distribution in a Single-Machine Production System with Breakdowns
Authors: Kempa Wojciech M. , Paprocka Iwona , Kalinowski Krzysztof , Grabowik Cezary
Published: October 2014

An operation of a single-machine manufacturing system is modeled by an unreliable finite-buffer-type queuing system with Poisson arrivals, in which service times, failure-free times and times of repairs are totally independent and exponentially distributed random variables. Applying the idea of embedded Markov chain and the formula of total probability a system of integral equations for the transient conditional queue-size distributions of jobs present in the system at fixed time t is built. The solution of the corresponding system written for Laplace transforms is obtained in a compact form using the potential technique.

Authors: Tulcan Aurel , Tulcan Liliana , Stan Daniel
Published: October 2014

The paper presents an approach concerning the CMM design. The first stage of this research deals with the acquisition and the development of knowledge about the CMM design. The main mechanical design aspects to achieve a high positioning and measuring accuracy are presented and two main objectives are assigned: high repeatability (design for repeatability) and high predictability of the machine response to the main error sources (design for predictability). In the second stage of this research the dynamic errors states for this CMM design have been analyzed. In high-speed measuring processes dynamic errors will have a great influence on the accuracy. This study has been performed by using finite-element analysis (FEA) of the mechanical frame. The total deformation of the mechanical frame for different accelerations of the moving assemblies has been calculated. The major deflections at the probe position due to the accelerations are obtained by using FEA. These results give a prediction about the dynamic error of the CMM.

This paper is a result of a research focused on statistical vehicles dynamics. Its main purpose is to establish mathematical description of vehicle dynamics based on statistically sufficient experimental data and using statistical instruments. The results are analytical expressions and graphical representations that can be used in situations other than those the data were obtained. Experimental research program objective was to obtain a variety of data to define the dynamics of a vehicle. It involved a large number of tests, more than 100, on different runways, pavement, mosaic tiles or asphalt. They were performed in various weather conditions, sunny and warm weather or rain or sleet and snow. The driving style varied between normal and sport ones. The experimental data were used in obtaining mathematical models that define certain dependency between dynamic parameters. There were issued multiple linear regressions with one resulting parameter. If we analyzed the models we issued we notice that the more factorial parameters are involved, the higher the accuracy of the model we get.

Analysis of Non-Classical Models which Have been Subjected to Percussive Loads Using Equations of Energy and Power
Authors: Jamroziak Krzysztof , Bocian Miroslaw
Published: October 2014

The article presents an analysis of impact energy dissipation process with selected non-classical dynamic models. Identification of impact energy dissipation phenomena in layered mechanical systems (for example: composite ballistic shields) is a great challenge, because on the one hand a model with parameters responsible for the energy dissipation is being sought on the one hand and on the other it is necessary to optimise the number of parameters. The sought model should be reduced to a simple description of the phenomenon and should contain a complex reproduction of the whole mechanical system. In this case the impact energy dissipation was described using selected degenerate systems. Models were treated by extortion surge having a specific impulse of force. The mathematical description of the pulse excitation was carried out using the energy and potency balance equations. The verification of mathematical identification equations was conducted using a computer simulation technique for the selected model’s parameters.

Published: October 2014

The paper deals with the analysis of a RPP sequential manipulator designed to be used for handling different loads, bringing them to a preset position. This manipulator is used to automating the store and transfer loads for improving working condition, avoid using human operations that require low-skills and reducing the risk of accidents. In the beginning, we performed a structural analysis of the manipulator. It has all the features of any industrial robots. Afterwards, we carried out a study of kinematics and dynamics for this RPP manipulator, using a simulation software package. The simulation results can be used for various purposes such as: trajectory calculation of characteristic point depending of variable couplings; determining whether to change the parameters of particular joint for achieving a certain trajectory of characteristic point; finding the force needed in joints to achieve a certain end-effectors trajectory; finding the kinematics of joint according to the driving force. This study is necessary to command and control system in order to obtain the desired motion. It also allows the choice of actuators of the manipulators. An experimental research was further conducted with the main goal to determine the motion law for the manipulator cinematic joints. We used Hottinger equipment consisting of transducers, amplifiers and a computer, using a parallel connection, data acquisition, type system. Eventually, with respect to the simulation and experimental research, we provide an algorithm for analyzing a sequential manipulator. It can be used to determine the forces that should act within the cinematic joints in order to get a certain trajectory of a characteristic point (that allows choosing the driving system during the design phase of manipulators or checking the driving system if the manipulator is already manufactured).

Mixed Reality as a Tool Supporting Programming of the Robot
Authors: Foit Krzysztof
Published: October 2014

Mixed reality is a term which covers a wide range of computer and real world interaction. This name refers to the picture shown on the display device, which consists of real and virtual elements. These elements are mixed in some proportion, so we may distinguish between augmented reality (where the real world dominates) and augmented virtuality (where the virtual world dominates). In most of cases a flat (2D) live image is processed, which makes this technology available in smartphones, car navigation systems etc. In the engineers world the mixed reality is used mainly in simulators and trainers, but also as supporting technology during manufacturing, assembly or maintenance process. This paper discuss different approach: mixed reality as a tool supporting programming of the robot. The main goal was to reproduce a path given by operator in off-line programming software using the visual representation of a real object. The system should be regarded as experimental one, because of early stage of development. It allows defining the coordinates of discrete points or to discretize the path and save this data for further processing. The operator should care the rest of programming task, but the use of the robot is reduced to minimum at this stage. The major disadvantages of the mentioned method are problems with accuracy and the invariable orientation of the tool used by the robot during the process they may be eliminated by using better video equipment and the specialized image processing routine. This paper presents the main assumptions of the method along with a possible solution of the problem.

Published: October 2014

Legs are the mostimportant elements for accomplishing human physical work includingtransportation or displacement. In this paper, a new mechanism for human legmotion assistance has been proposed for rehabilitation purposes. The structureof human leg and its motions have been used as inspiration for design purposes.For a simple control algorithm, the proposed mechanism for the legs mustgenerate an ovoid path of the foot, by uniform rotating of actuating crank. Themechanism must generate an approximately linear trajectory of foot duringpropulsion. The resulting linkage is a single degree-of-freedom (DOF)mechanism, which exemplifies the shape and movement of a human leg. Theactuator of the mechanism is located in the upper portion of the linkagesimilar to it in a human leg. The mechanism is simulated and tested to verifythe proposed synthesis. A 3D model of the proposed system has been elaboratedin Solid Works®, booth for design and simulation purposes. Simulation resultsshow that the proposed mechanism performs movements similar to those of a humanleg. Maple and Adams software packages are used to simulate and validate the usabilityof the mechanism. The proposed mechanism demonstrates that a one DOF closedloop mechanical linkage can be designed to the shape and movement of the bipedhuman walking apparatus. The proposed mechanism is suitable for the fabricationof legged robots. Proportions of the linkage are estimated utilizinganthropometric measures of the human leg.

Published: October 2014

Common methods for reducing image size include scaling and cropping. However, these two approaches have some quality problems for reduced images. In this paper, we propose an image reducing algorithm by separating the main objects and the background. First, we extract two feature maps, namely, an enhanced visual saliency map and an improved gradient map from an input image. After that, we integrate these two feature maps to an importance map. Finally, we generate the target image using the importance map. The proposed approach can obtain desired results for a wide range of images.

Recurrence Plot Analysis of HRV for Exposure to Low-Frequency Noise
Authors: Chen Shih Tsung , Chou Chia Yi , Tseng Li Ho
Published: October 2014

Previous studies have indicated that the chronic effects of exposure to low-frequency noise causes annoyance. However, during the past two decades, most studies have employed questionnaires to characterize the effects of noise on psychosomatic responses. This study investigated cardiovascular activity changes in exposure to low-frequency noise for various noise intensities by using recurrence plot analysis of heart rate variability (HRV) estimation. The authors hypothesized that distinct noise intensities affect cardiovascular activity, which would be reflected in the HRV and recurrence quantification analysis (RQA) parameters. The test intensities of noises were no noise, 70-dBC, 80-dBC, and 90-dBC. Each noise level was sustained for 5 min, and the electrocardiogram (ECG) was recorded simultaneously. The cardiovascular responses were evaluated using RQA of the beat-to-beat (RR) intervals obtained from ECG signals. The results showed that the mean RR interval variability and mean blood pressure did not substantially change relative to the noise levels. However, the length of the longest diagonal line (Lmax) of the RQA of the background noise (no noise) condition was significantly lower than the 70-dBC, 80-dBC, and 90-dBC noise levels. The laminarity showed significant changes in the noise levels of various intensities. In conclusion, the RQA-based measures appear to be an effective tool for exposure to low-frequency noise, even in short-term HRV time series.

Published: October 2014

The travel and tourism industry is one of the main sources of income in Thailand. People choose to travel around the world, as a way to relax and enjoy their time. Users search information from many resources before and during their travel. We grouped the mobile tourism applications into two main groups in order to analyse the nature of information in the tourism applications. Social network provides rich collaborative user-generated information. We found that most tourism applications require personal information and pre-existing association in order to get information. We argue that, in tourism, a user requires instant and easy access to information. So the social network might not be an appropriate option. Therefore we propose a simple collaborative user-generated content application, which has a location awareness chat system. We aim to provide an application with self-sufficient information that allows the user to instantly share, search, and comment on information at anytime and anywhere. Moreover, the location awareness chat system is introduced to provide instant firsthand information to the users as well.

Published: October 2014

Currently it is a critical situation when every year due to aggressive external factors thousands of listed buildings are under threat of destruction around the world. In many ways, the state of affairs is due to the lack of effective integrated management of listed buildings. Lack of integrated tool for operating of different data, which determines the structural integrity of listed buildings and condition of environment, has led to the fact that most of the regional and municipal authorities are not able to handle the diversity of information. To address these problems specialist of Department of City Planning and Community Development of Rostov State University of Civil Engineering developed the methodology and information-analytical support system of listed buildings’ preservation. This support is able to analyze different types of data and to use different IT technologies such as CAD systems, GIS-technologies and databases. Information technologies in management of listed buildings can help municipalities with a limited budget to get the most out of existing services as these are the technologies that help different departments to work more closely with each other.

Then we employ Matlab to do the interpolation fitting, drawing the change of actual capacity of the road from the beginning time of an accident to the time when traffic resumes. The work comes to a conclusion that the change of the capacity at the cross section has a pattern of periodic fluctuation.

Formative assessment emerged under humanism and constructivist theory of learning is being accepted and used in English teaching. Lots of research focuses on general influence of formative assessment on English teaching. There is little special research concentrated on influence on influence of formative assessment on motivation. This thesis intends to study the influence of formative assessment on motivation and further explores the different influence of formative assessment on extrinsic motivation and intrinsic motivation. The results of this study show that using formative assessment is more effective to foster college students’ motivation on English learning, especially has stronger effect on extrinsic motivation but less than on intrinsic motivation during an academic year. As a result of motivation strengthened, English achievement is improved.

Landing mats are essential for the safe completion of landing impact in gymnastics. Shock absorption and stability during landing impact is provided by both gymnasts’ ability and mat properties. The aim is to determine the influence of different characteristics of mat on mat-ground reaction forces. A subject-specific model with 12 segments rigid body and a model about landing mat in floor exercise were developed by computer simulation. The stiffness and dampness of landing mat influenced the peak of vertical ground reaction force and time to peak, but there were significant correlations between the friction of landing mat and the peak of horizontal ground reaction force and time to peak.

Published: October 2014

In this study, the adaptive network-based fuzzy inference system (ANFIS) was used to generate the fuzzy rules for discussing the effects of gas and electricity price on residential sector’s energy consumption rate (RSECR) in Taiwan. Twenty seven fuzzy rules of Sugeno type were generated from ANFIS. It was found that the fuzzy rules did not reveal the significance when the situation was extreme, i.e. one input variable was low but another one was high. When all three input variables fell in the low degree of membership, the output RSECR values tended to be “high”. When all three input variables fell in the high degree of membership, the output RSECR values tended to be “low” even “negative”. It suggested that higher energy price would inhibit RSEC.
Function Effects Post-Evaluation for Substation Construction Project Based on Multi-Level Extension Assessment Method

Published: October 2014

This paper established a multi-level extension model for function effects post-evaluation of substation construction project, the model not only reduces the influence of subjective factors on the evaluation results, but also can determines the key factors which affect the quality of the evaluation results and overall developing trend of the project and provides some suggestions for the project late operation. Taking into account the fact that the element of the judgment matrix formed by traditional AHP is a certain value and may lead to a big difference from the judgment matrix formed by the different group of experts, thus reduces the credibility of the evaluation results; In order to overcome the problem, this paper introduces the concept of interval number, the maximum and minimum of judgment matrix elements relative importance comparison are used as the upper and lower limits of interval number respectively. Interval number are used as the elements of judgment matrix to make the evaluation result more rational. At the end, a practical 220kV substation construction project is taken as an example to verify the validity and rationality of the established model.
