The Problem of the Weak Ground Floor in the Buildings Located in Seismic Areas

AL QATAMIN Atef1 ABSTRACT

A building is considered to have a low floor when that floor stiffness is less than 70% than the next floor rigidity or stiffness of floor that is less than 80% higher than average stiffness following 3 floors. Floor few accounts for a majority of lateral movements, resulting in structural damage to the columns in that floor. Key words: floor weak, stiffness, lateral displacements

Hydraulic Systems of Equipments for Casting Asphalt

B�L��OIU Victor2, BORDEA�U Ilare3, POPOVICIU Mircea 4, IONESCU Gheorghe5,

SETTI Aldo6 ABSTRACT

The present paper is concerned with the problems occurring in the design and manufacturing of the mobile equipments destined for asphalt pouring. The continuous development of the civil engineering works implies a new conception of the equipments used in this branch of industrial activity. That is why, the range of the devices used in civil engineering works utilizing hydraulic actuators became in our days very large, this category of equipments becoming one of the principal users of hydraulic driving systems. After presenting some principles aspects of driving equipments for mobile devices there are presented various types of hydrostatic actuators used in mobile equipments. Analyzing the specific design problems, we insisted upon the computation of the hydraulic diagram putting in evidence some examples of hydrostatic traction in close circuit with integral hydrostatic transformation. The main advantages of the hydraulic driving systems are: the stability of the moving velocity, rapid adjustment or inversion of the movement and the possibility to standardize both the elements and the whole system. These advantages determined the rapid extension of the hydraulic drive systems in the civil engineering plants. Key words: hydraulic driving systems, civil engineering plant, asphalt pouring equipments

Damaged Over Pass in Re�i�a – Rehabilitation Procedure

BOTA Adrian1, BOTA Dorian2,

BOTA Alexandra3 ABSTRACT: The over pass to be rehabilitated is situated in the northern part of the city Re�i�a and passes the switch yard for railways and the Barzava river. The substructure of the over pass, consisting of two spans situated on the left bank of the Barzava river, is under passed by a junction arm for the access on the over pass. In the winter of 2007 an over gauged transport has heavily hit the three monolith reinforced concrete girders of the superstructure. In spite of the significant damages, the superstructure has kept its bearing capacity needed for a light traffic with a maximum load of 3,5 t. The paper presents the damages of the superstructure and also the rehabilitation solutions, which involve the adjustment of the geometry of the under passing junction arm as well. Key words: Over pass rehabilitation, Reinforced concrete, Lifting system, Road geometry

Actual Problems in the Theory of the Structured Design

C�T�RIG Alexandru1, KOPENETZ Ludovic2

ABSTRACT

The theory of structured design aims at acquiring the basic knowledge for the scientific view upon the construction and the constructive element calculation and the ensemble of the structures. Observing correctly the interaction phenomena (structure - terrain, structure - dividing walls and existing plumbing) asks for an adequate modeling and usage of certain complex numerical methods. The structured design theory has to perform the not at all easy task of conveying important notions upon the behavior of the construction elements and of the bearing structures under the action of certain causes to the young engineers and architects, who are at the beginning of their professional road. The professional becoming of the engineer or architect depends on the manner they understand the elements of the structured design theory. Key words: seismic analysis, compound structures, structured modeling

Short History of the Finite Elements Method

DANCIU Alexandra-Denisa3 ABSTRACT

Finite element method (FEM) is known in literature as finite element analysis (FEA) and it is a numerical method used to obtain approximate solution of a differential equations system. Initially the method was created to address the complex equations of structural mechanics and elasticity. The exactly time of the method has occurred is still unknown. A number of authors argued that the method appeared in the 1950s with the development of aerospace, but there are other sources that put the first steps taken in the evolution and development approach long before the 20th century, Rayleigh's variational methods (1870) or residues weighted Gauss (1795). This work aims the development of what are now the most common numerical methods in engineering calculation.

Anchoring solutions for CFRP lamellas used in flexural strengthening of RC beams

DIACONU Dan1, STOIAN Valeriu2, FLORU� Sorin-Codru�3 ABSTRACT

In the paper are presented two anchoring solutions that were already experimentally tested in the laboratory. The first one involves the anchoring of the lamella at both ends using steel plates connected to the concrete elements by bolts. The second solution suggests the anchoring of the lamella on its entire length using distributed steel bolts that are chemically anchored in the concrete element. Those anchoring methods were applied in order to avoid the bond issue appeared between the support layer (concrete), epoxy resin and CFRP lamellas, which could lead to important faults and reduced effect of strengthening intervention. Because of this bond issue, in most situations the failure of the strengthened element occurs due to debonding mechanism, long before the capacity of the lamella is reached. This phenomenon usually arises because of the lack of attention paid to the preparation of the support layer by neglecting the concrete’s quality, by poor knowledge of technological requirements or by poor qualification of the workers who apply this strengthening technique. Key words: strengthening, RC beams, lamellas, CFRP, anchoring

Determination of the Linear Thermal Transmittance Coefficient for a Non-Insulated Thermal Bridge

DIAO Ousseynou4, MOGA Ioan5 ABSTRACT

The objective of the paper is to recommend a numeric model for calculating the linear thermal transmittance coefficient in steady state regime at the connection of two walls in a non insulated building, with the calculus program MATLAB. In the two studied cases from the paper the exterior convective flow, the difference in temperature between the 2 environments and the thermal transmittance U [W/(m2 K)] were used, in order to determine the linear thermal transmittance coefficient � [(W/(m K)]. With the help of the coefficient � the corrected thermal transmittance Uc [W/(m2 K)) was determined, which helped in tacking account of the thermal losses through thermal bridges. The heat losses through thermal bridges are a continuous research objective of the researchers in the field. The main CONCLUSIONS that can be drawn from the obtained results (14,86 % represent thermal losses through an “L” element and 37,84% through a “T” element), is that these thermal losses must be taken into account when evaluating the thermal balance of the element and of the building envelope.

Impact of renewable energy in modern architecture FALUB Cosmin 1, BLAGA Casian-Alin 2

ABSTRACT Our planet is warming because of human activities affecting the environment. Climate change is caused by a number of things, and it will take an enormous amount of concerted effort to fix it. It involves thinkers, politicians, professionals, and the public. Architects and engineers will have a major role to play in resolving the associated problems. This paper explores various architectural designs that areemployed to achieve a low-energy built environment. Future buildings will be actively involved in the adoption of life cyrcle cost accounting all based on economic values and ecological systems, accelerating the use of sustainable technologies and enstablishing a system engeneering concepts in all phases of building design, financing and the operation. A move to new ways of measuring costs will also serve to educate the public about the real costs of owenership of property, occupation and operation, togheder with energy and non- energy contributions that a properly designed buiding a health fair personal confort and durability. The paper concludes that designersof the next generation of buildings, whether residential, commercial, or institutional,should aim for “zero energy” buildings in which there will be no need to draw energy from a region’s power grid. In this approach, climate and environment are used to advantage erather than being treated as adversaries and buildings become sources of energy, like batteries. A few illustrative buildings.

The Analysis of the Junctions of Layered Composite Structures

HAD�R Anton1, CONSTANTINESCU Ioan2, MOTOMANCEA Adrian3

ABSTRACT Complexes stratified composite structures can be design and executed in very good

reliability and safety conditions. In many cases difficulties in local state stresses quantitative evaluation may appear. The most important difficulties are in the different constructive parts junction areas. The analyses of those difficulties imply technological problems which determine intimate configurations for composite material structures and general calculus using efficient methods. The analysis of local state stresses can determine optimisation of the configuration to some junction types taking into account different goals. In the paper the constructive and technological aspects of the most important types of junctions are described. For some of them the models and the results of finite element analyses are presented.

Key words: junction, composite materials, finite element method, delamination, laminate

L�DAR Ioana2, PRODAN O.3

ABSTRACT The paper presents a few numerical results and the concluding remarks on

performance based analysis carried out on semirigid multistory steel skeletal structures. The semirigidity is associated to the beam – column connectivity and is governed by the well known bending moment – relative rotation analytical models. The structures are provided with the usual beam – column semirigid connections of engineering practice. The fundamentals of performance based analysis is shortly presented. Two multistory semirigid steel structures of frame type are analyzed. The loading is of pushover type (statically nonlinear analysis) and is associated to the gravitational loading. The analysis is carried out in the geometrically nonlinear elasto – plastic domain. Usual static and kinematic parameters related to performances of (steel) structures located in seismic areas are computed, analyzed and focused on. These parameters are: base shear –lateral top displacement relation, bending moment – relative rotation relations in the semirigid beam – column connections, plastic collapse mechanisms. Key words: steel skeletal structures, seismic performances, semirigid beam - column

Integrative Design – An Essential Component of Sustainable Management

MIRCEA Drago�4

ABSTRACT Premises for sustainable management of the projects are strictly related to

performance, quality and overall project costs in relation to the whole life cycle. So the design of the building, is to store and correlate knowledge and expertise of all the factors that will contribute to the definition, implementation, operation and maintenance of the building. Integrative design is the process of design and project management by a multidisciplinary team that information to the different phases of the project are organically incorporated into the process in order to create integrated solutions to support innovation in construction. So the importance of targeting the design process to a collaborative integrative factors present in different phases of a project becomes an essential component in defining a sustainable management process. The coagulate vision of the two concepts is just their orientation for the project life cycle.

Key words: designing integrative, sustainable management, project life cycle

Experimental and Theoretical Research on the Energy Performance of Windows with Triple Glazing

MOGA Ligia1, MOGA Ioan2

ABSTRACT The paper presents results of experimental investigations carried out on a PVC

frame windows and triple glazing. The measured experimental results were compared with those obtained from a numerical calculation, using the program “WINDOW WALL-S”. With the help of the calculus program, the heat performances of the window were determined, taking account of the fittings in the PVC frame. This has a great impact on the obtained values of those performances compared with the ones obtained using the10077/1 and 10077/2 norms which do not take into consideration these fittings.

There is a good match between collected experimental results and the ones obtained by numerical calculations under the same laboratory boundary conditions, where the measurements were done. Key words: energy economics, mathematical modelling, simulation, heat transfer,

Motivations for underground living

MURE�ANU Ioana1

ABSTRACT Along with the demographic growth the spaces intended for residential living are

lessening and it seems that many people will choose, if they have not already chosen to live as our ancestors: in the underground or in earth sheltered homes. Because of the climate changes we cannot deny that our world is heading toward a turning point its relationship with the surrounding environment. The natural deposits of fossil fuel to produce electricity Consumed - currently used for different purposes, one of which is the adjustment of the temperature in our homes - is predicted to be Op in the next century. These constructions, the underground or the earth sheltered ones, have the advantage of maintaining a quasi constant temperature inside the house throughout the year.

Underground City

MURE�ANU Ioana2, MURE�ANU Florin3,

MOLDOVAN Silivan4 ABSTRACT

Underground architecture can be considered as a part of the natural or rupestral architecture, an architecture whose own beauty is unspoiled by human intervention. In the past historical periods, natural caves and cavities or better called Grotto, were used as a place of refuge or as a meeting point by a society which from the point of view of intelligence was not yet fully developed. The benefits of such a shelter were obvious even to the primitive man, and this is the reason they have started to be used as permanent living spaces. The next step was the construction of homes in the form of artificial caves, first dug in the ground, and later in stone. Evolving, the human needed more space and more comfort. He will achieve this by further excavations to expand the living space, through extension or external additions "built" that harmonize with the natural environment. Afterwards, these shelters will start to be adapted to all human needs, and when certain areas - those intended for Rituals or worship - begun to be improved with decorations and cave paintings, architecture received for the first time artistic valences. Key words: Utopia, Shelter, Habitation

West University of Timi�oara – The Mural Decorative of the Central Architectural Building

NOVICOV Ramona-Adela1, FASOLI Vilma2

ABSTRACT

Hans Fackelmann’s name is among the most significant ones of the Romanian Avant-garde that became conspicuous in the contemporary architecture. The design of the University of Timi�oara in the first years of the 7th decade brought about important works within the field of visual arts because the architect was frequently working closely together with the artists belonging to the powerful 1970s avant-garde in Timi�oara. The most spectacular work of monumental art from the building complex is the one signed by Romul Nu�iu. Unfolding itself “in the mirror” on the walls of the central hall, the double mural composition belongs to the most authentic Romanian Avant-garde art both by its complex concept situated at the borderline between figurative and informal language and by the technique of coloured fused cements. The artist from Timi�oara was concerned about the complex theme of the “Dynamic Universe” all his life. In his ample work that decorates the University hall, the chosen theme is the dialogue between the dynamic universe of Science and Classical Studies, of the binomial Art-Literature. Created in 1973 in a modular vision, perfectly adapted to the rigors of the architectural field and ennobled by time, Romul Nu�iu’s work remains an exceptional accomplishment in the context of Romanian contemporary art. Key words: mural, avant-garde art, contemporary architecture

The Rehabilitation of Children Palace in Oradea – Case Study

PU�CA� Cristian2, PANTELIMON-NEGRUT Viorel3

ABSTRACT The rehabilitation project of Children Palace in Oradea, regards two major

approaches. The complexity of the project resulted on the one hand from the need to provide extra useful space inside the building and on the other hand because of the difficulty in configuring the final image of the monument, as much as possible closer to the original. First of all the technique and materials adopted, in the proposed intervention is a testimony of the modern approach to the subject. On the other hand the architectural intervention regards the importance of a good execution, but also a good knowledge of the historical past of the building, a good knowledge of conservation and rehabilitation principles and not in the end a proper knowledge of art, history and architectural evolution of styles.

Modern Combustion Exhaust SCHREK Laszlo1

ABSTRACT From the beginning of humanity, fire has always been a focal point in the lives of

people. Residue evacuation had become a necessity when more efficient, closed or semi-closed, fireplaces were developed, the evolution of chimneys being closely tied to the heating appliances’ development in time, being these domestic or industrial.

Chimney systems that serve last generation heating appliances, based on burning different types of fuels, are subject both to complex inner actions of physical or chemical nature (high temperatures, thermal shocks, and corrosive effects of acid condensate) and exterior actions of climatic (frost-defrost) or dynamic nature (wind, earthquake) and, as such, they have to correspond to several functionality- and durability-related requirements. Consequently, even the simplest chimney is a construction subset or a construction in itself, complex trough the thermal-, burned gas flow- and mechanical strength and stability processes it has to fulfil. These functional and structural arguments lead to a special structure of chimneys.

Along with the increase in construction volumes, the necessity for shortening the execution period, combined with maintaining a constant level of quality, became even more important. Thus, prefabrication, as a technological process was introduced also to the area of chimney production.

This paper presents two types of prefabricated chimney systems, which both from a conceptual and used materials point of view represent a high level of performance. The systems presented are intended to serve single heating appliances, regardless of the combustion chamber type or the used fuel, respectively more than one appliance, placed at different levels of a building, ensuring, this way, the needed combustion air from the outside.

The article includes a presentation of the two types of chimney systems, consisting of specification of the areas of use, presentation of the construction solution (multilayer-type walls, inner ceramic liners with profiled surface, of special burned fire clay), presentation of the operating principles, the different specific execution details, and the base components’ physicochemical features (density, compression resistance, resistance to high temperatures and thermal shocks, resistance to thermal diffusion and acid environment, etc.).

Taking into consideration that the value of a technical solution consists of its utility, at the end of the paper, the advantages of these chimney systems are being presented, of which we mention wide practicability for energy efficient buildings, short installation time, safety in use and a long time warranty.

Structural Approach of a Prefabricated Chimney SCHREK Laszlo,1

TALPO�I Atanasie2

ABSTRACT The goal of an efficient resistance and stability designing is to obtain the structure’s

safety, considering every unfavourable situation that may occur during its operation, firstly through calculation procedures, and secondly by estimating the prefabricated system’s behaviour in, as much as possible, normal conditions.

A prefabricated chimney system’s components, due to their physical and mechanical features, to different types and heights of joining, have different roles in assuring bending rigidity of the section. The tension and displacement state caused by extreme actions is complex, due to the dynamic interaction between the system’s components. Consequently, the dynamic answer of this type of construction differs from the one of a homogenous structure, which can be described by vertical continuity.

The conducted experimental research was meant to study prefabricated chimney systems’ behaviours when dynamic actions are applied, with relative level displacements. This paper presents, briefly, the course and results of the tests made, giving details about the structural rigidity, maximal tolerable alterations of form and about the needed horizontal forces for reaching different displacement levels, both for the unconsolidated version and by adding possible stiffening/consolidating solutions.

By applying the specific technical regulations, presented in this paper, by considering different adaptations and extents of specific norms and by analyzing the results of the experimental research, an easier structural analysis of the prefabricated chimney systems can be conducted to determine the most favourable (from both a technical and economical point of view) stiffening/consolidating solutions. Key words: chimney system, dynamic actions, rigidity, displacements, consolidation

The Necessity of GIS/LIS Standards

CRISTEA C�t�lina1 ABSTRACT

The intense utilization of GIS technology (Geographic Information Systems)/LIS(Land Information System) in the last decades, leaded to increasing efforts of standardization for data structures and interchange methods for spatial data. The integration of data that derive from different sources or different fields of activity into a common project is a thing absolutely necessary and partial achieved by actual standards. To allow data exchange and communication between different systems without important data looses have been tested different systems of standardization.

Generally speaking, data interchange between different systems and data bases relay on standard formats defined by different organizations – national or international ones- such as ANSI or ISO. There are also developed un-official standards, which are promoted by individual companies, for example the ESRI standards. A thing that cannot be solved directly is the integration of data gathered from different sources, data that have a high rang of incompatibility. Data might be incompatible due to their resolution, coding attributes or ways of collecting. Eliminating the incompatibility causes is based, most of the cases, on predictions.

This article will focus on the main issues about the necessity of a certain GIS standardization, issues that put face to face regional, national and international authorities. There will be examined the main issues that make the standards needed and useful in the GIS/LIS systems Key words: GIS, LIS, Standardization

SZEPESNE-STIFTINGER Maria2 ABSTRACT

The usage of Geographic Information Systems (GIS) has been rapidly increased and it became the main tool for analyzing spatial data in many engineering applications and decision making activities. These applications and activities require more and more the three-dimensional reference space (surface), known as Digital Terrain Model (DTM). Quality assessment of data is a critical parameter for DTM production and it relies heavily on statistical methods. In contrast, visual methods are generally neglected despite their potential for improving DTM quality. In this paper, several enhanced visual techniques and for quality assessment are described and illustrated with areas and datasets selected from Oradea hill’s area.

Theoretical and applied aspects on 3D measurements using terrestrial laser scanning

JOCEA Andreea - Florina1, DIDULESCU Caius2

ABSTRACT In geodetic measurements an object is generated mostly by the points - known as

meshing operation in geometric space. These points should be determined their mutual position in space. Mutual position is usually given by a spatial distance and its orientation to a reference direction. In many practical cases the spatial length can be described through horizontal distance and difference components, which add a horizontal and vertical angle of orientation. Over time for raising of the space’s points have developed various methods such as tachometric methods, which involve lifting of the details point by point and attributes for each point, respectively photogrammetric methods and, more recently, laser scanning used for lifting mass of object points. Compared with tachometric measurements where time for points meshing of the objects and assigning each point is very large, terrestrial laser scanning is a new measuring technique by which can be three dimensional position of objects with high accuracy, high speed and with a high spatial resolution. Key words: sensors, terrestrial laser scanning, point cloud

Aspects of a Support Network in Condition in Vlaha, Cluj County

ORTELECAN M.1, BUDIU V., CIOTL�U� Ana, DEAK Jutka, POP N., OPRE C.

ABSTRACT This work make reference at the concrete conditions from vlaha township, where a

series of points from the triangulation net have been destroyed, and the rest of points, in limit number, are in majority non stationary points. By following the conditions imposed by OCPI for the integration into the National Coordinate System of those real estate which are the object of transactions, the problem become difficult when must be realized the precisions imposed by the standards. In the absence of a global positioning technique GPS, the realization of the coordinate scheme is possible by framing at the limit the thicken points, but the majority of cases doesn't satisfy the precision conditions.

Thus, when inserting the points "201" and "202" by following the method Hansen (fig.1) the verification consist in comparing the distance measured among the points whit those resulted from coordinates.After the estimation we find out a 0.569 m difference, value that doesn't fit the precision conditions. Another variant taken into study, was the backed polygonometry on the two point without orientation vis, whit the determination of the sides over the non stationary points utilizing trigonometrically relations into the triangles 1-500-1004 and 500-1-1005. It must be mentioned that the values obtained by following this method fit the precision conditions. Key words: survey network, real estate, coordinates

Automated and Cinematic Measurement Control Systems in the Monitoring of Mining Constructions

R�DULESCU Adrian T.G. 1, R�DULESCU Gheorghe M.T. 2,

B�DESCU Gabriel3, R�DULESCU Mihai V.G.4

ABSTRACT The security of mining constructions works demands a periodical monitoring of the

structures. The current methods (such as triangulation, leveling, vibrating strings or mechanical extensometers) are often of tedious application and require the intervention of specialized operators. The application of the new monitoring concepts to the specific needs of structures opens new perspectives in the long-term monitoring of all works of some importance such as mining constructions, bridges, tunnels, dams, airport runways, domes, unstable soils and rocks, just to name a few. Construction safety cannot be conceived except by assuring a careful geometric monitoring in static, cvasistatic or cinematic regime of the execution and time behavior of the performed structures. Among special structures (mining structures, bridges, dams, very tall buildings) this aspect is in the center of attention. This is how new methods appeared for assuring the geometry, taking into account the perturbing factors – the main one being the action of the wind. Situated at the border between structures safety – meteorology – surveying, the new domain is therefore an interdisciplinary one. The purpose of the paper is to present this new chapter of surveying and its role in structures monitoring. The conclusions of the paper will emphasize the fact that monitoring in the cinematic regime, though it has a very strong interdisciplinary character, is a developing of classic surveying methods in the cinematic space and therefore should be considered as a distinct and separate chapter. Keywords: security of mining constructions, construction safety, typical sensors, safety –

meteorology – surveying

GIS in Mining & Exploration, as a Tool to Based Mining Revenue Management System

R�DULESCU Mihai V.G. 1, R�DULESCU Adrian T.G. 2,

R�DULESCU Gheorghe M.T. 3 ABSTRACT

Geographic Information Systems (GIS) are often used to meet infrastructure network goals in a variety of fields, such as transportation, electric distribution, property assessment or mining industry.

GIS offers multiple applications in the mining industry with tools to gather, compile, process, display, analyse, and archive extensive volumes of data. The use of Geographic Information Systems (GIS) is a powerful tool and is gathering momentum in the mining industry. Of particular interest is the GIS capability to integrate communications across departments and mine sites. GIS technology must constantly evolve to meet the changing needs of the mining industry, both in Exploration and mining terms. The question remains, is the romanian mining industry ready for these changes? A well designed, implemented, and supported GIS management structure is critical in the success of mining operation. This application of GIS in underground mining concentrates in four technical areas: land ownership and mineral claims, exploration management, production, and mine safety. The benefits of consolidating and archiving claim data and the ability to georeference property maps defined in local coordinates into state coordinate system is of paramount importance to a land and exploration manager. In the production area, GIS facilitates the optimal siting and querying of service installations relative to production centers to meet the production parameters. In mine safety, the siting of refuge chambers relative to production centers is optimized and areas of potential safety concern are identified utilizing GIS’s proximity analysis. This paper describes examples of technical applications in underground mining concentrating in four areas: land ownership and mineral claims, exploration management, production, and mine safety. Key words: Geographic Information Systems (GIS), application of GIS in underground

mining, GIS technical applications

RUS Tiberiu1, MOLDOVEANU Constantin1,

MARCU Constantin 1, DANCIU Valentin1

ABSTRACT Based on the previous geological and geophysical information a special network for

geodynamic monitoring of the Romanian territory has been designed and achieved. The network consists of three lines crossing the major lithosphere contacts: the Tornquist-Teisseyre Zone (TTZ) separating the East European Plate from the Intra-Alpine Microplate (IaP), Peceneaga-Camena Fault, as the boundary between EEP and Moesian Microplate (MoP), and the Trans-Getica Fault (TGF) between MoP and IaP. The fourth line is crossing the Vrancea active geodynamic area located in the bending area of East Carpathians. The project INDEGEN (grant CEEX-2 MENER no. 732/2006-2008) started in 2006 with a duration of three years, managed by the Institute of Geodynamics of the Romanian Academy in co-operation with other scientific organizations: Technical University for Civil Engineering – Faculty of Geodesy, University of Bucharest, Geological Institute of Romania, and National Institute for Earth Physics. The main task of geodetic investigation will consist in repeated GPS and leveling observations combined with other observation techniques as gravity. The geodetic network was connected with CEGRN (Central European Geodynamic Network) by GPS and leveling observation campaign performed in July 2007. A new campaign will take place in 2008.

ABSTRACT In this article we point out a cutting edge method of teaching that is not very wide-spread as

of today. We wish to draw attention to the fact that traditional methods are apt to fail when applied to students reaching higher education with greatly varying levels of existing background knowledge to build on. We need to find methods that can effectively grab the attention of students, inspires their creativity, and involves them in the process of teaching/learning. For this end, we find the methods of constructivist pedagogy highly expedient. The range of possibilities can be further widened by applying features of web 2.0. Applicability of the methods is demonstrated through an examples, from a specialised studies.

Data Components Handling of a Graphical Cadastral Database Using the Visual LISP Program

DIDULESCU Caius1,

JOCEA Andreea - Florina2 ABSTRACT

Visual LISP programming is able to address specific issues, including in the handling of data in graphical cadastral databases. This article presents the data handling component of a graphical database application that allows manipulation of blocks of graphics databases.

AutoCAD includes an integrated development environment (Integrated Development Environment), called Visual LISP, which contains a compiler, a debugger ("debugger"), catalogs of visual functions and visual controls to simplify writing of the AutoLISP programs.

One of the features offered in Visual LISP is access ability of the informations from AutoCAD database. The Visual LISP functions allow extracting of the components data of an object, such as its layer or color. In the same manner, those specific data objects can be manipulated using Visual LISP functions.

Some entity data components extraction from the graph database is a process, which is conducted on several stages. The first step usually is the same, namely: geting of the entity’s name. Without it, all data components of it are inaccessible. The AutoLISP function with which could be obtain the name of an entity is entsel (represent the shortcut for entity selection), allows selection of an entity and returns two informations, meaning the entity name and the use point coordinates when the entity has been selected. The entity’s name is the first element of the list and can be isolated by using car function. Key words: graphic database, Visual LISP

The Principles of Surfaces Modeling and Their Protection

HERBEI Octavian1, HERBEI Mihai2,

ULAR Roxana3 ABSTRACT

Surface modeling is that process by which a graphic is natural or artificial surface through one or more mathematical equations. Modeling of land surface is a special case of the areas that must be taken into account for some specific problems which are related for representation of the Earth or forsome portions of it.

Digital model of an object or phenomenon is consists from a systematic data collection (database) which describe a three-dimensional coordinate system, arbitrary or particular, the shape and characteristics of the object or status/achievements of the phenomenon (the conversion as digital image) and also allow, through adequate computer programs, the deduction in new points of the object shape and characteristics or of the phenomenon.

The digital terrain model represents an information "tool" consisting from terrain data and software that is an essential part of a GIS system. The digital terrain model (DTM) consists by 3 subsystems:

1. The altimetry digital model - DEM comprising shares, slopes, curves, etc. 2. The planimetric digital model – DPM, which comprising planimetry data and

elements. 3. The digital model of objects nature – DEMM, which includes pedological,

geological, hydrological data, etc. Among the areas where the digital model of terrain can have an immediate

application may include: analysis of telecommunications systems (with development the land profiles, analysis of propagation, transmission networks and other specific applications), the pipeline networks design (e.g. headrace water), command and control of the various systems, and in all other areas where is necessary to know the elevation information at various points of a surface. Key words: modeling, protection areas, slope, GIS

Hazard Phenomena in the North-East of Hunedoara County (Romania)

ILIE� Dorina-Camelia1,

BLAGA Lucian2, RUS Ioan3,

B�IA� �tefan4 ABSTRACT

The area to be analyzed, which contains 13 administrative – territorial units from the NE of Hunedoara county, is grafting on geological-geomorphologic structures from the Metaliferi Mountains. For the evaluation of natural and anthropogenic hazards phenomena we took into account the existent methodology from Romanian legislation: Law 575/2001, HG 447/2003. Thus, out of the range of the natural hazards phenomena landslide and floods were chosen. In order to evaluate the anthropogenic hazards we considered the atrophic pressure exerted at the level of different land categories. Many evaluation classes have resulted for each type, respectively hazard category analyzed, mentioning that in the case of floods we had to deal with two working units: UAT (territorial-administrative unit) and flooding strips with different insurance degrees.

Key words: geological-geomorphologic structures, anthropognic hazrds

Obtaining Cadastral Plans Methods for Introducing of the General Cadastre in Romania

MUNTEAN Mihaela-Denisa 1

ABSTRACT The need and importance of the cadastre for the economic activity and social peace

is within recognized, so that concerns still continue to find ways to obtain the cadastral plans as part of the basic documentation which is necessary in introduction of the cadastral genera, and the current project in this area is: The Project on Expanding EU Support for Agriculture Restructuring, which is initiated by the National Agency for Cadastre and Land Registration.

At present land records system, consisting of Cadastre and Land Registration of all lands and buildings are no longer in pain, because that begins to approach to the modern European requirements. That is because:

- Plans and land registers, meaning here inclusive that’s incomplete transcriptions and inscriptions, or damaged, has began to be updated;

- Introducing of a new land registration required by law it is now starting. Taken together, the cadastre and real estate advertising aimed multi-state

purposes for the state and for the property owners to solve some capital problems, such as: obtaining primary data on the land, defending and enforcing of the intellectual property in the actual state institutions as arbiter and guarantor of this right, setting fair fees and taxes under the tax laws, etc.

In conclusion, in this summary, it can be said that in present we can not imagine a democracy regime, with the rule of law and a modern economy, without an effective system of cadastre and real estate advertising, as effective guarantor of the property entered into the Constitution rules.

Key words: Basic Land Plan, the land of the overall plan, orthophotomap

Forest Cover in Cri�ului Repede Valley - A Quantitative Study

PODOLEANU Doina1

ABSTRACT

Crisului Repede valley is located from north to south in the middle of the Bihor County and from west to east between Crisurilor plain and the northern part of Apuseni Mountains. It is important as a natural, social and economic interference area with geographically unifying characteristics both for the western region and whole Romania.

Crisul Repede valley has divers’ topography. A flat valley lies between the eastern limit of Oradea city and Subpiatr� village and is followed to east by another one which reach the Borod village. The first terraces of the Plopisului hills (Oradea and Bistrei hills) rise to the north and the Padurii Craiului hills (T��adului, Hidi�elului and Cord�ului hills) to the south.

In this paper we analyse the forest cover for an important sector of Bihor County. Forests have an important role in economy, environment, for human beings and determine the specifics of land cover.

One of the important evolutionary determinants of specific regional ecosystems, with significance thematic in our study performed is vegetation. In this regard, hills and corridor sectors of Cri�ului Repede follow the forest area, forest-steppe zone and to a lesser extent of the meadow area.

In our studied region, because of the special conditions of its habitat, since ancient times results an intense degree of popular mostly complained that increasing of the agricultural areas. This aspect conducts to removing of the natural vegetation, manifested through deforestation and grubbing and even through remediation of the wetlands areas, with watercourses planning. Recent, was organized, in economic purpose, some hydro-energetic rearrangements.

In terms of optimal land using, the forest land represent an important factor in protection against soil erosion and to reduce the loss of the solid material. This percent is appreciatively to 80%.

Key words: Ecotype, Biodiversity, Forest cover, Real Estate

Monitoring System of Waters from Cri�uri River Basin

SUIUGAN Marius-C�lin 1 ANDRI�CA Simona-Gabriela2

MAN Teodor-Eugen3 ABSTRACT Development and modernization requirements of Waters Monitoring National System are covered by the provisions of the European Directives and international agreements and conventions. The monitoring process is in close connection with the assessment process of water quality, this being considered in sequence, and with a final result, characterization and knowledge of the status of surface and underground waters. The number of monitoring sections must be choose in the way to permit the assessment of the ecological and chemical status, for all water bodies.

Integrated water monitoring system includes the following 6 sub-systems: • rivers; • lakes • coastal waters; • groundwaters; • transitional waters; • sewage.

Media investigations are represented by water, sediments and biota, quality elements, minimum monitoring parameters and frequencies of those being provided by the WCD (Cri�uri Waters Directorate), according with the program type.

Monitoring of the waters status Cri�uri river basin is accomplished with monitoring programmes established on Article 8 (1,2) of the C.D. (Cri�uri Directorate). Sampling and analysis of biological and physic-chemical elements is performed by specialized laboratories of the regional or basin network of the National Administration "Romanian Waters”.
