High concentrations of salt fog or sea salt particles causedpitting corrosion to aluminum materials: Cl- in the salt fogcan strongly penetrate and damage the surface passive film of aluminum materials and further lead to pitting corrosion.
The contact corrosion between aluminum and steel materials will develop primary cells to cause electrochemical corrosion, further exacerbating the degree of corrosion.

Keywords: Surveying architectural plane in-house, laser reticule system, non-metric digital camera Introduction As a symbol of ancient civilization, there are more than 50 billion square meters existing buildings in China and lots of structures built with traditional materials still exist and remain in service nowadays.
These techniques require substantial effort and do not give satisfactory results about the structure's geometry and materials properties.
For scanning with laser, cracks and materials of buildings might not be able to be distinguished by using this method.

Variable name Initial Unit Description 1 Freshwater source Fs - Water source (Ground water or surface water) 2 Tank classification Tc - Classification of tank according to the elevation relative to ground level 3 Tank material Tm - Tank building material 4 Tank volume Tv [m3] Tank capacity 5 Tank height Th [m] Tank height above ground 6 Network length Nl [m] Water supply network length 7 Service pipe number Sp - Number of hydrants available in the network 8 Investment cost Ic [€] It is the initial investment cost of the work.
This can be explained by the fact that, in general, for lower tank heights, the tank is classified as resting on ground and it is built in concrete, whereas for medium or high tank heights, the tank classification is high and its material is steel.
However, this variable has a significant correlation with the variables tank classification, tank material and tank height.

According to the Beer’s law [6], the extinction ratio of the transmission I / I0 is represented as; (2) where, k is the extinction coefficient of the materials and d is its thickness.
The Beer’s law, on the other hand, benefits from its measurement range much wider than those detected by the Fabry-Pelot interferometry, and also useful for determining the optical constants of the materials.

Many studies have been carried out to obtain magnetic titanium dioxide photocatalysts [1], in which the titanium dioxide could be deposited onto the surface of magnetic material The iron oxides, such as maghemite (γ-Fe2O3) and magnetite (Fe3O4) [2], are often selected as the magnetic core due to their excellent magnetic property and low price.
Characterization of the materials.
X-ray diffraction (XRD) patterns of the materials were obtained with CuKa radiation source.
The magnetization values decreased with the increase of coating times, because of the content reduction of magnetic material, i.e. γ-Fe2O3, whose contents are 49.6wt%, 34.0wt%, 24.3wt% in γ-Fe2O3-SiO2, SiO2/(γ-Fe2O3-SiO2) and TiO2/SiO2/(γ-Fe2O3-SiO2), respectively, according to ICP results.

In 1988, was in the laboratory of Palo Alto Research Center of Xerox for computer science, Weiser first described the ubiquitous computing: “Offer each office and everyone with hundreds of wireless computing devices .The operating system propose new requirements, like user interface, network, wireless, display and many other aspects .We call our work as “ubiquitous computing”, which is different from the PDA, Dynabooks or palmtop computer information .It is invisible, also is a kind of ubiquitous computing and it does not depend on any form of artificial equipment.”
This system allowed the learners to download ELDIT learning materials from the Internet through windows operating system PDA, and to learn offline.
Accessibility: Learners can access to learning materials include text, pictures, video, audio and other forms.
After a stage of measurement and evaluation, the system can provide the evaluation result and the related auxiliary materials immediately to help students adjust their learning behaviors, so that they can achieve more effective learning.

True and Nominal Stress During Low Cycle Fatigue Tests of Metals MROZINSKI Stanislaw 1 1 University of Science and Technology in Bydgoszcz, Faculty of Mechanical Engineering Al.
Introduction In the fatigue life calculation method proposed in [1] material data determined during low cycle fatigue tests were used.
Material data obtained as result of use of them is characterized by quantitative similarity which refers to the determined material data.
The life calculations consist of number of use (even to several millions) of determined material data [7].
