This paper gives an overview of the mathematical methods currently used in quantitative structure-activity/property relationship (QASR/QSPR) studies. Recently, the mathematical methods applied to the regression of QASR/QSPR models are developing very fast, and new methods, such as Gene Expression Programming (GEP), Project Pursuit Regression (PPR) and Local Lazy Regression (LLR) have appeared o...
Underwater Wireless Sensor Networks (UWSNs) handle many underwater applications such as environment monitoring, surveillance and navigation. These generate varied types of traffic continuous bit rate, sporadic different packet sizes, leading to additional QoS requirements that are application dependent. This paper presents the development a Quality Service Aware Source Routing (QASR) protocol. ...
BACKGROUND Archaeobotanical samples of barley (Hordeum vulgare L.) found at Qasr Ibrim display a two-row phenotype that is unique to the region of archaeological sites upriver of the first cataract of the Nile, characterised by the development of distinctive lateral bracts. The phenotype occurs throughout all strata at Qasr Ibrim, which range in age from 3000 to a few hundred years. METHODOLO...
qasr or hasr (restriction) is one of the techniques of semantics that can be used in different ways. most of former thinkers believed that despite differences that exist in how these methods convey meaning to readers or audience, they function similarly. this research is a descriptive-analytical study of methods of qasr and tries to elaborate on the fundamental differences among these methods. ...
Qasr-e Shirin owes its prominence primarily to the Sassanian period and the attention the region received from Khosrow Parviz. Khosrow took the first steps to make Qasr-e-Shirin habitable by constructing a complex consisting of a palace, a fortress, a religious building, a defensive wall and a water conveyance system. Later, Qasr-e-Shirin is mentioned in several texts and travel itineraries. Th...
Novel N-substituted tetrahydro-β-carboline imidazolium salt derivatives proved to have potent antitumor activity in past research. The Topomer CoMFA and CoMSIA function in Sybyl-X 2.0 software was applied for the identification of important features of N-substituted tetrahydro-β-carboline-imidazolium salt derivative moieties. In the case of Topomer CoMFA, all the compounds were split into two f...
