Up till now, only linearly polarized microwave radiation are employed by the Synthetic Aperture Radar (SAR) systems onboard spaceborne platforms. In general, such linearly polarized SAR (LP-SAR) systems are very sensitive to Faraday rotation in the ionosphere and platform posture, both of which will contribute to system noise superposed on the resulting backscattering signature. So as to improv...

Since November 2006, DLR operates F-SAR a new airborne SAR sensor beside its experimental airborne SAR sensor E-SAR. F-SAR is a totally new development utilizing most modern hardware. It is presently operated in X-band and has been supplemented recently being fully polarimetric. F-SAR already accomplished several flights and acquired SAR data in different operation modes, amongst others in alon...

objective: soil salinity is one of the major worldwide environmental constraints affecting agricultural production in arid and semiarid regions. lack of proper management of water and soil resources lead to increase soil salinity and reduce soil fertility. on the other hand, it seems simple and cheap method of measuring soil salinity is necessary. the aim of this study was to determine the rela...

Since the end of the 1991 Gulf War, there have been reports of unexplained, multisymptom illnesses afflicting veterans who consistently report more symptoms than do nondeployed veterans. One of the many possible exposures suspected of causing chronic multisymptom illnesses Gulf War veterans is squalene, thought to be present in anthrax vaccine. We examined the relationship between squalene anti...

This article explains the shift in Russia’s foreign policy strategy towards Middle East. Particularly, it aims to address question of why Russia supported UNSC Resolution 1970 Libya 2011 but refused cooperate with West Syria. In this article, is argued that West’s use authorization no-fly zone as a green light for military intervention paved way obstinacy To test hypothesis, focus on foreign-po...

works of the most prominent authors such as: Zarrindast, Isma'fl Djurdjanr, MansUr b. Muhammad b. Ahmad, Hadji Zain al-Attar, and Muhammad Arzani. Appreciating this, Richter-Bernburg puts an intense effort into the analysis of the content of each manuscript, which, unusually for collections of Persian manuscripts, is not overshadowed by the beauty of the miniatures and illustrations. This enhan...

This study is an attempt to carry out a comparative analysis using Natural Semantic Metalanguage (henceforth NSM). The offering routine patterns of native Persian speakers was compared with that of Native American English speakers to see if it can provide evidence for applicability of NSM model which is claimed to be universal. The descriptive technique was the cultural scripts approach, using ...

Viseme (Visual Phoneme) clusterin every language is among the most important conducting various multimedia researches as reading, lip synchronization and com pronunciation training applications. With re that clustering and analyzing visemes are lan processes, we concentrated our research on P which indeed has suffered from lack of su paper, we used a hierarchical approach for c in Persian langu...

The cursive nature of Persian alphabet, and the complex and convoluted rules regarding this script cause major challenges to segmentation as well as recognition of Persian words. We propose a new segmentation algorithm for the main stroke of online Persian handwritten words. Using this segmentation, we present a perturbation method which is used to generate artificial samples from handwritten w...

Speech recognition in Persian (Farsi) has recently been addressed by a few native speaking researchers and some approaches to isolated word and phoneme recognition have been reported. A main bottleneck in this research field is the lack of a recognition-specific speech corpus. In this work, a phonetically balanced speech database of Persian has been modified and used in continuous speech recogn...
