A signific~mt component of a user raodel in au infornration-seeking dialogue is tim task-related plazl motivating the information-seeker's queries. A number of researchers have Irmdeled the plan inference process and used these models to design more robust natural language interfaces. However in each case, it has been assumed that the system's context model and the plan under construction by th...

the study aimed to investigate the microsporogenesis, tapetum and pollen development in petunia hybrida juss.under control and air pollution condition. the connective shows a well-developed placentoid, giving thesporogenous tissue a crescent-shape. the sporogenous tissue of each of the four anther locules is surrounded bydimorphic tapetum. the outer (towards the epidermis) and inner (towards th...

The paper presents the concept of controlling designed optoelectronic scanning and tracking seeker. above device is intended for so-called passive guidance short-range anti-aircraft missiles to various types air maneuvering targets. In presented control method, modified linear-quadratic regulator (LQR) estimation input signals using extended Kalman filter (EKF) were used. LQR regulation utilize...

this paper is based on a research carried out for evaluation of addict rehabilitation centers in iran. the research has been conducted by application of survey method, questionnaire technique and interview with help seekers (addicts) in qarchak varamin rehabilitation and de-addicion center in south- eastern of tehran. this study has been carried out in two stages of pre-treatment and rehabilita...

In this paper, the stability of a class Liu–Wang’s optimal eighth-order single-parameter iterative methods for solving simple roots nonlinear equations was studied by applying them to arbitrary quadratic polynomials. Under Riemann sphere and scaling theorem, complex dynamic behavior method analyzed fractals. We discuss all fixed points parameter spaces starting from critical with Mathematica so...

Crowdsourcing ideation contests allow solution-seeking firms (seekers) to solicit ideas from external individuals (solvers). Contest platforms often recommend seekers provide examples of solutions (i.e., seeker exemplars) guide and inspire solvers in generating ideas. In this study, we delve into solvers’ process examine how different configurations exemplars affect the quantitative outcomes sc...

OBJECTIVES We performed the current study to (1) understand the distribution of culturable airborne bacteria over a one-year monitoring period, (2) confirm places in stations where airborne bacteria are highly detected, (3) understand the factors that affect concentrations of airborne bacteria and (4) compare the distributions of airborne bacteria and fungi in railway stations in Japan. METHO...

hospitalized patients have a potential risk for nosocomial infections. airborne fungi are one of the main causes of fungal infections in this group. the objective of this study was to investigate the concentrations and species of airborne fungi in two general hospitals in shiraz, southern iran. air samples were collected from high-risk wards, using settle plate method. fungal colonies were iden...

Hardware in the loop simulation (HILS) is used to evaluate the performance of rosette scanning seekers, decrease the cost of design and construction. Using this simulation, we can test the system in several cases with different algorithms. Hence the results can be readily verified by simulations within this framework. In this paper, the rosette pattern along with the target and flares is simula...
