Authors: Bondrea Ioan , Rosca Lucian Eugen 
Published: August 2014

AbstractThe automotive industry faces future important changes through adoption of several new complex technologies like” X-by-wire” systems for vehicle dynamic control and high focus on green technology, fuel efficiency hybrids and electric vehicles. The implications of these technologies require in-depth understanding of the vehicle behavior during lifetime cycle, in order to reach a maximum optimized design. Therefore this paper introduces an analysis of a long-term capture data collection from a fleet of serial production vehicles in normal everyday use, as a solution to the lack of information available to describe the vehicle dynamics and load over the systems in a sufficient way. The analysis brings knowledge-based information, where before was difficult to answer and where statements were mainly based on subjective explanation. Results reveals important information describing load cycles during vehicle lifetime for different control events with focus on the braking events.

Authors: Catelly Yolanda - Mirela 
Published: August 2014

AbstractIn the increasingly interconnected contemporary society, employers commonly expect the engineering graduates to possess, alongside academic success evidence, a range of soft skills, of which scientific and technical communication, particularly in a language of international circulation, ranks first. This demand has led to creating and implementing a modular flexible Scientific and Technical Communication in English - STCE original course of the CLIL (content and language integrated) type. The paper aim is to evaluate the course impact, with a view to increasing its effectiveness and success by further amendments. This has been done by designing research, based on triangulating questionnaires and interviews addressed to both graduates who took (or not) the STCE course during their Master’s or Doctoral education, as well as to their employers.

Published: August 2014

Abstract
Kanban is often seen as a central element of Lean manufacturing and perhaps is the most used product application system. Kanban is the essence of the concept that a supplier or a products deposit must distribute the components in place and at the time the production needs them so that there are no stocks in the production area. The implementation of the Kanban concept must go through four different stages; each of these stages having more steps to be followed. The paper shows some analysis elements regarding the degree of knowledge and practicability in the study of the management of the Kanban systems implementation to be followed by students in technological practice.

Authors: Brad Stelian , Fulea Mircea , Mocan Bogdan , Brad Emilia 
Published: August 2014

AbstractTo keep up with the dynamics of nowadays researches and technologies, study programmes - particularly master programmes - need to continuously evolve. Additionally, rigid regulations drive the structure and content of such programmes. Adding competitiveness to these as a must, one can easily infer that building (or updating) a study programme is not an easy task. Moreover, expectancies and requirements from industry might even interfere with specific rules that study programmes have to be compliant to. This paper introduces an approach to overpass the challenges above, by employing the TRIZ-M framework. Problem definition, needs, performances, constraints, technical conflicts and innovation vectors are the key ingredients of the framework that has been used to support the development of a competitive master study programme in Robotics at the Technical University of Cluj-Napoca.

Published: August 2014

AbstractCarbon foot printing became an important term for surprisingly many people in the last years. It is very important that people learn what effects may have carbon foot printing on their lifes and how it’s produced. The term “carbon foot printing” is just a name which is the result of global warming potential. Carbon foot printing is considered a very popular buzzword in Romania in the last year. The carbon footprint measures total greenhouse gas emissions caused directly and indirectly, by a person, organization, event or product. In Romania the carbon emissions are the consequences of burning of fossil fuels and manufacturing of cement, and the value of CO2 emissions in 2008 was 94,660(kt). People can do training or courses to learn more about the meaning of carbon footprints, their impact on the environment and calculation of the carbon footprint by measuring the CO2 equivalent emissions.

Published: August 2014

AbstractIn the context of competition in higher education environment the university type of public institution ensures high quality, accessible, challenging university and research programs, expertise services based on a strong motivation, commitment and professional attitude from the teaching body and students. National documents promoted by ARACIS show that “The internal dimension of academic quality is built based on the legislation in force and according to the specific of each university, its tradition and cultural heritage. It is fully under the responsibility of each university. In this approach, quality assurance becomes a process adapted to the existing institutional specific and it is instituted as a mechanism through which academic results or performances are constantly improved”. Communication quality management is integrant part of the institutional quality management system and to this extent the formulation of general criteria, quality indicators and standards is considered so that emphasis is placed not only on the organization’s conformation to a set of predefined or predetermined quantitative and qualitative conditions but also on the deliberate, voluntary and proactive commitment of the institution for accomplishing certain performances that can be proved by effective results. Within the presented paper, in considering the importance of communication for all process participants, we have identified and defined a series of qualitative indicators which, through content and structure, hold a certain weight in communication quality management implementation in the organization. In formulating the communication strategies, in designing the informational system of a public institution in general and of the university type of public institution these groups and subgroups of indicators, which represent the quintessence of the apprehensions, believes related to sending the information formulated by the stakeholders and actors of the communicational field from all structures of an academic institution, are suggested.
Challenges Of Transition Towards Entrepreneurial University
Authors: Zajko Marian , Pezoldt Kerstin 
Published: August 2014

AbstractThere are several key external challenges to be mastered in the transition from the traditional university towards entrepreneurial university which are transformed into internal challenges. Unlike the business schools the management structures and environment of an university of technology may be often very cautious about implementation of the entrepreneurial elements in the technology and science study and research programmes. Often they have to be confronted by the requirements of students and businesses for more entrepreneurship education and skills in the university graduate profiles to accept this. This paper examines fundamental challenges of implementation of the concept of entrepreneurial university in two European universities of technology with direct central public funding which gradually covers less and less its future development needs. The current status of transformation towards an entrepreneurial university at the Slovak University of Technology in Bratislava compared to the University of Technology Ilmenau is described, analyzed and the next steps put forward.
Teacher - Student Graphical User Interface For Testing And Comparing The Performance Of Adaptive Algorithms Used In Smart Antenna Networks
Authors: Scutariu Adrian , Zedevei Dalina , Jurian Mariana 
Published: August 2014

AbstractSmart antenna networks are receiving a lot of interest in these days, as new advanced and fast processors are being developed. Capable of pointing the main beam in a certain desired direction and create nulls in the radiation pattern in the direction of interference, smart antenna networks are a good solution in a bandwidth limited environment as the number of users continuously grow. This technique is called beamforming. For many years smart antennas were not practical as they involve the use of a processor that runs an adaptive algorithm. Slow processors meant low speed of convergence and a slow adaptation. There are a lot of adaptive algorithms that can fur fill the job that a smart antenna system has to accomplish. The main purpose of this paper is however to present the main advantages of creating a MATLAB GUI (Graphical User Interface) in order to study these algorithms. The GUI described studies 62 adaptive algorithms, some described in literature, some propose by the authors. We will make a short description of the LMS (Least Mean Squares Algorithm), the APA (Affine Projection Algorithm) and the GASSAPA (Gradient Adaptive Scalar Step Size Affine Projection Algorithm) and compare them with the use of the graphical interface.

Published: August 2014

AbstractDue to a medium-low level of young students’ technical knowledge from previous school classes the first year of university seems to be very difficult. The complex phenomena and the abstract concepts represent the first lectures avoided by the students if the temporal burden becomes uncomfortable. Therefore the lecture has to be designed in which the prospective engineer clearly recognise their profit. Using the modern educational instruments as DidaTech Platform, CAD or C++ program presentations in higher education for engineering the level of comprehending and interest in the profile subjects should increase.The main concern of this paper is to demonstrate how using electronic methods young engineers learn about the descriptive geometry and improves the student’s intellectual capability of space perception. This will be absolute necessary for the students’ preparation for the Mechanical Drawing and CAD subjects.
An automated microinfiltrometer to measure small-scale soil water infiltration properties
Authors: Gordon Dennis C. , Hallett Paul D. 
Published: August 2014

Abstract
We developed an automated miniature constant-head tension infiltrometer that measures very small infiltration rates at millimetre resolution with minimal demands on the operator. The infiltrometer is made of 2.9 mm internal radius glass tube, with an integrated bubbling tower to maintain constant negative head and a porous mesh tip to avoid air-entry. In the bubbling tower, bubble formation and release changes the electrical resistance between two electrodes at the air-inlet. Tests were conducted on repacked sieved sands, sandy loam soil and clay loam soil, packed to a soil bulk density ρd of 1200 kg m-3 or 1400 kg m-3 and tested either air-dried or at a water potential ψ of -50 kPa. The change in water volume in the infiltrometer had a linear relationship with the number of bubbles, allowing bubble rate to be converted to infiltration rate. Sorptivity measured with the infiltrometer was similar between replicates and showed expected differences from soil texture and ρd, varying from 0.15 ± 0.01 (s.e.) mm s-1/2 for 1400 kg m-3 clay loam at ψ = -50 kPa to 0.65 ± 0.06 mm s-1/2 for 1200 kg m-3 air dry sandy loam soil. An array of infiltrometers is currently being developed so many measurements can be taken simultaneously.
Computational issues of solving the 1D steady gradually varied flow equation
Authors: Artichowicz Wojciech , Szymkiewicz Romuald 
Published: August 2014

Abstract
In this paper a problem of multiple solutions of steady gradually varied flow equation in the form of the ordinary differential energy equation is discussed from the viewpoint of its numerical solution. Using the Lipschitz theorem dealing with the uniqueness of solution of an initial value problem for the ordinary differential equation it was shown that the steady gradually varied flow equation can have more than one solution. This fact implies that the nonlinear algebraic equation approximating the ordinary differential energy equation, which additionally coincides with the wellknown standard step method usually applied for computing of the flow profile, can have variable number of roots. Consequently, more than one alternative solution corresponding to the same initial condition can be provided. Using this property it is possible to compute the water flow profile passing through the critical stage.

Authors: Aydin Ozgur , Ellidag Hamit Yasar , Eren Esin , Ay Nurullah , Yalçınkaya Soner , Yilmaz Necat 
Published: August 2014

SummaryBackground:Oxidative stress may be involved in the pathogenesis of every human disease. To understand its possible role in benign prostatic hyperplasia (BPH), we measured the overall oxidative status of patients with BPH and the serum activity of the high density lipoprotein (HDL)-related antioxidant enzymes paraoxonase 1 (PON1) and arylesterase (ARE).Methods:Fifty-six urology outpatient clinic patients with BPH (mean age 64±8.6 years) were prospectively included in the study. Forty volunteer healthy controls from the laboratory staff (mean age 62±10 years) were enrolled for comparison. Serum total antioxidant status (TAS), total oxidant status (TOS), PON1, ARE, and HDL levels were measured by commercially available, ready-to-use kits.Results:Serum TAS and HDL levels were significantly lower in the BPH group than in the control group (P=0.004 and P=0.02, respectively). No significant between-group differences were observed for TOS levels or PON1 and ARE enzyme activities (P=0.30, P=0.89, and P=0.74, respectively). In the BPH group, the calculated parameters PON1/HDL and ARE/HDL were significantly higher (P=0.02 and P=0.04, respectively).Conclusions:Our findings agree with the previous reports of impaired oxidant/antioxidant balance in BPH patients. The activities of HDL-related enzymes between groups with significantly different HDL levels may be deceptive; adjusted values may help to reach more accurate conclusions.
