Azerbaijan is one of the most active segments of the Alpine-Himalayan seismic belt and marks the junction between the African-Arabian and Indian plate to the south and Eurasian plate to the north. Several regional earthquakes have been strongly felt and caused damages in and around Tabriz during history. For example, the magnitude 7 to 7.7 Tabriz earthquake in 1780, which is the most strongest experienced one in Lesser Caucasus and east of Turkey and caused severe damage in Azerbaijan territory including Tabriz City. The urban area of Tabriz City lies on Miocene to Quaternary soft sediments （clays, sands, silts, and gravels.） resting on an old Tertiary basement. Previous studies have shown that the thickness of such soft sediments could largely influence the site response in case of an important regional earthquake. The accurate information about historical earthquakes and new faulting is an important tool for viewing the active tectonic and analyzing the earthquake risk and seismic migration. Historical records of earthquakes in Tabriz based on macro and micro seismic observations cover period of 1,000 to 1,400 years. Our study aims at mapping the seismic response of a pilot zone of Tabriz for different earthquake scenarios, a simple but robust.

Soil stabilization is a set of measurements and treatment which apply to soils. The main reason of the measurements is to prepare a soil type which covers the geotechnical engineering necessities like shear resistance, bearing capacity, compressibility, etc.. Stabilization methods are generally limited into mechanical and chemical properties of Kaolinite soil. Actually, the first method is by use of stabilization binding agents and the second one is done via construction machines like rollers and tampers. Generally, civil projects or earth projects are mostly getting along with clay soils. Therefore, a sufficient knowledge about the soil property is needed due to their special behavior beside sufficient stabilization methods. In the research, a comparison between lime and cement stabilization agents via proctor standard test is conducted to evaluate mechanical and chemical stabilization methods encountered clay soil sample with kaolinite mineral from Fars region, Iran.

Seismic events are very complex spatial-temporal phenomena. Seismic catalogues, reporting information about spatial-temporal distribution of the main shocks, are nowadays available for many seismic areas in the world, very often major events mark the beginning of a series of earthquakes （aflershocks） whose frequency and energy are meanly decreasing in time down to the background level of activity. Azerbaijan is one of the most active segments of the Alpine-Himalayan seismic belt and marks the junction between the African-Arabian and Indian plate to the south, and Eurasian plate to the north. The cluster of earthquakes that struck near Varzeghan-Ahar was centered near the Gosha-Dagh fault, but preliminary data suggested that the fault was not responsible for the temblor. On the late afternoon of Saturday, August 11, 2012, the northwest of Iran was shaken by two of the strong earthquakes in Iranian history. First was hit by Mw （moment magnitude scale） = 6.4 Richter at local time 16：54 （12：23 GMT （Greenwich Mean Time））, and about 11 min later, an Mw = 6.3 struck 10 km to the west. The spatial-temporal clustering of micro earthquakes （aftershocks） near Varzeghan, is parameterized by means of a generalized passion model. The region has known faults but numerous smaller or deeply buried faults remain undated, according to the Geological Survey of Iran.

A low cost service robot was designed and implemented specifically to be used in service industries e.g. hotels. This service robot can deliver a requested payload (towels, bed-sheets, drinks or toiletries) to a customer. As evident with modern technology, robots are assisting man in several avenues of the service industry. This designed service robot can propose an error free service, work around the clock and consume less time with requested tasks. The prototype can handle two commands received from two different rooms simultaneously. It has the ability to choose to always deliver to the closest room from its base first. Also, it has the function to carry two different types of payloads in two of its compartments and to lift up the desired payload ordered by the customer using a scissor lift system. The service robot also uses a touch screen to interact with the customer. The algorithm of the design ensures that the payload will always be delivered to the right customer in due time.
