Optimum design in civil structures like domes and vaults is a very old and ongoing research field.
Introduction The use of concrete shell structures in construction is motivated by their structural efficient response to transverse loading, which made them a solution that satisfies the needs of covering large spaces in different civil engineering projects.

Concrete is a mixture of the cementing material, aggregate and water in a certain proportion and is the most main materials of the civil engineering materials.
Introduction Concrete is the most main materials of the civil engineering materials.
The concrete has many properties, e.g. high compressive strength, endurance, wide range of strength, and it is widely used in all kinds of civil engineering, shipbuilding industry, machinery industry, Marine development, geothermal engineering.
So the prediction of concrete strength is important and it is useful information for designers and engineers.

This paper offers researchers in transport engineering a method for reducing urban traffic congestion by planning for pedestrians.
The conclusions present some applications of this technology and underline the importance of teaching it in engineering.
Other professionals like civil and transport engineers, urban planners, economists or even journalists do not have the opportunity to learn in universities about today’s available land and traffic management technologies, even though they may use these technologies to create a support for certain professional decisions.
Besides the lack of education, two other reasons have kept this technology away from Romanian engineers, which are license prices and lack of data.
However, with proper training of students, Romanian cities with civil engineering faculties could develop such studies, and even include traffic data in the surveys taken.

Reliability of Approach Slabs and Modelling of Transition Zones of Bridges Kamil Laco1, a, Viktor Borzovič 1,b 1 Slovak University of Technology, Faculty of Civil Engineering, Radlinského 11, 810 05 Bratislava, Slovak Republic akamil.laco@stuba.sk, bviktor.borzovic@stuba.sk Keywords: approach slab, elastic support, modelling of interaction Abstract.
The complex models of transition zones with the brick elements of the soil and the interaction with the reinforced concrete slab with the soil embankment are compared with simplified models used by civil engineers.
The selected models of soil for analysis were: single parameter Winkler model, two-parameters Winkler-Pasternak model, iterative procedure for obtaining soil resistance coefficient via Soil-In from SCIA Engineer and 3D finite soil elements model with SOFiSTiK software.
After verification of theoretical results, the final goal of the study should be the engineering tool for the design of approach slabs.

The document structure can outline civil aviation authority’s view on how flight data analysis program, which may be embodied within an operator’s safety management system.
The document structure can also describe the principles that should underpin an flight data analysis system acceptable to the civil aviation authority (CAA).
Through this co-operative development work many farsighted operators have demonstrated the safety benefits of FDA such that the International Civil Aviation Organization(ICAO) recognizing the potential for accident prevention, introduced provisions for a flight data analysis program to be part of an operator’s accident prevention and flight safety program.
This paper can provide the power help to engineer to complete effective the assignment of FDA.
