Coal mining subsidence seriously affects the mine natural and ecological environment. Leveling is the traditional method to monitor the coal mining subsidence. It is possible to monitor the subsidence by gravimetry instead of leveling based on the negative linear correlation between the gravity change and the height change. Equations are derived to monitor the subsidence by gravimetry in the pa...

The project scheduling and resource allocation problems have been studied using different optimization methods. The resource leveling problem was proposed to reduce the resource fluctuation and was always studied independently resource constraint problem. For example, resource-constrained project scheduling problem (RCPSP) was proposed to optimize scheduling under resource constraints. This res...

kurdish language is one of the iranian languages and the historical study of the phonetic system of khorasan kormanji dialect, can clearly show that this language has been under the influence of iranian languages, especially persian language. the author of the article has used prof. tsablof’s (the most famous russian orientalist) publications, to show the persian language influence on khorasan ...

Simultaneous optimization of time, cost, and utilized resources in a construction project is vital. This paper presents a GA based model for determination of the best combination of the time, cost, and resources in a multiple resource constraint problem. The proposed model considers both resource allocation and leveling simultaneously. Since the problem is assumed to be resource constraint, res...

Although the traditional permute matrix coming along with Hopfield is able to describe many common problems, it seems to have limitation in solving more complicated problem with more constrains, like resource leveling which is actually a NP problem. This paper tries to find a better solution for it by using neural network. In order to give the neural network description of resource leveling pro...

Laser-controlled land leveling system can obviously improve the planeness of the field and enhance the efficiency of irrigation. The 3D topographic information was needed for project design and evaluation of laser land leveling. In order to obtain the topographic information efficiently, an onboard field 3D topography surveying system was developed. The surveying system consisted of a measuring...

COVER Immunostained fl uorescence microscopy image of memory engram–bearing cells (red) in the dentate gyrus of a mouse hippocampus (image width: 1.5 millimeters). These cells were genetically tricked to express the protein channelrhodopsin-2 during memory formation, thus becoming responsive to light stimulation. When the cells were activated by light, the mice simultaneously associated a genui...

karaji has introduced and explained the leveling instruments which were used at that time, in his book inb?t? al-miah al-khafiyyat (exploration for hidden water). added to the four studied leveling instruments, karaji introduces two more; “scaled vertical level” and “scaled telescopic level” which he mentions as his own inventions. in this paper after presenting these first four, the two levels...

-The responsiveness of female White-crowned Sparrows (Zonotrichia leucophrys nuttalli) to male songs in their natal dialect (Clear) or in an alien dialect (Buzzy) was evaluated by measuring string-gathering and papershredding in a laboratory experiment. Females hearing Clear dialect songs gathered more strings than did females hearing Buzzy dialect songs. More females hearing Buzzy songs shredd...

sarhaddi balochi dialect, a language variety of western (rakhshani) balochi, employs derivation through affixation as one of its word formation processes. the purpose of this article is to present a synchronic description of the way(s) different derivational affixes function in making complex words in sarhaddi balochi as spoken in granchin[1] district located about 35kms to the southeast of kha...
