The use of chemical anchors for the connection of existing structural elements with
the new elements during strengthening of existing structures is quite a preferred
method. Since in our country, chemical anchors are being widely used for repair and
strengthening works, there should be a standard of design and application on this topic.
Up to now, research done on the topic of chemical anchors, are mostly carried out on
concrete blocks of compressive strength 20 MPa and higher. Since parameters such as
distance from the edges, embedment depth and group effect were mostly ignored, the

The purpose of aggregating rubber is to increase concrete’s flexibility, elasticity, and
capacity to absorb energy. In some application of concrete, it is desired that concrete
should have low unit weight, high toughness and impact resistance. Although
concrete is the most commonly used construction material, it does not always fulfill
these requirements. In order to improve elastic properties of concrete and recycle the
waste materials, new applications have been realized recently. One of these
applications is the utilization of discarded tires in order to use together with
aggregate. ...Daha fazlası
Nowadays, Expert System (ES)s are used widely in many areas to solve real world problems. Artificial Intelligence (AI) techniques are used to obtain timely and accurately decision about solution of daily problems in ESs designing because AI can mimic behaviours and thought system of people. Especially in medical area, there are many researches and applications using ESs based on various AI techniques to obtain diagnosis for any diseases.

The understanding of sediment transport with fluid in pipes is one of the important issues in hydraulics engineering. If the fluid velocity is lower than a critical value, a stationary cuttings bed develops, which may cause excessive head loss. In this study, a Fuzzy Logic (FL) model is developed to estimate stationary cuttings bed thickness inside the annulus. Experimental data is collected from literature in order to train proposed models. Results showed that the cuttings bed thickness could be estimated using the developed model with a reasonable accuracy when compared with the experimental ...Daha fazlası
THE EFFECT OF PULSED ELECTROMAGNETIC FIELDS FOR IN VITRO WOUND HEALING EXPOSURE SYSTEMS
SUMMARY
Electromagnetic fields have achieved important role as stimulator and therapeutic facility in biology and medicine (Blank & Findl, 2013). The effects of low magnitude, low frequency pulsed electromagnetic fields have been a period of study since past few decades, which was mainly on the treating soft tissue injuries, skin ulcers, nonuniform bone fractures and degenerative nerve healing (Hug & Röösli, 2012b). Chronic wounds are a major healthcare problem for patient morbidity and contribute signi ...Daha fazlası

The housing sector is one of the largest sector responsible for energy consumption in the world and Turkey. Sustainability is an emerging issue as energy related problems arises throughout the world. The sustainable sources are both clean energy sources and mostly renewable. Therefore, especially in terms of economy, these new energy sources are important opportunity for countries dependent on other countries energy. Turkey is rich in sustainable resources and especially Izmir province has good potential in terms of solar, wind and geothermal energy which are the most important sustainable sou ...Daha fazlası
The scarcity of suitable land for construction of engineering facilities and shortage of natural earth aggregates has highlighted the need for finding innovative way of construction. Nowadays problematic soils such as: soft clay, organic soils and liquefiable soils can be improved to the required civil engineering requirements by application of soil stabilization. Soil stabilization is a method intended to increase or preserve the stability of soil mass and chemical alteration of soil to improve engineering properties.
Generally, ground treatment techniques used are: densification, reinforcem ...Daha fazlası
Urban regeneration greatly affect marginalized groups both across the world and in Turkey and therefore it is a hot topic in the public discussions of urban context. One of those marginalized groups are Roma communities. Their neighborhoods, particularly inner urban areas, face social and physical decay due to discrimination against Roma communities. To address these social and physical problems, urban regenerations projects have been launched in Turkey in the name of improving life standards of Roma citizens. However, implementations could not go further than improving physical conditions of ...Daha fazlası
