the current status and quality of urban and regional development has been criticized by many academics and professionals in different fields. at city centers in addition to traffic congestion, population growth, urban and regional sprawl and suburbanization have resulted in unsustainable conditions in many cities all around the world. in this regard, different aspects of urban form, especially ...
Temporal coordination of services, as a crucial aspect of integration in public transport systems, has always been a big concern for transit planners and schedulers. One of the major issues in the way of coordinating transit services is the lack of a robust measure of effectiveness for assessing the quality of temporal coordination in public transport systems. Even though the network-wide summa...
Bus rapid transit is an innovative, high capacity, lower cost public transit solution in metropolitan cities. Idea is to dedicate lanes for quick and efficient transport of passengers to their destinations. In the present investigation the environmental impact assessment of bus rapid transit in Tehran metropolitan city is brought out. For this purpose bus rapid transit Lane No. 10 is investiga...
River bed sand and gravel are utilized more than mountain materials due to their availability and closeness to the transit roads and sites of usage. Excessive and non-technical extraction of gravel and sand bring a kind of interference in them, leading to many negative consequences. Therefore, presenting solutions to reduce these impacts and infilling mining pits are essential. In this researc...
introduction: hydronephrosis is one of the major causes of referring infants for nuclear medicine investigation. renal dynamic study is the most reliable investigation for such children. however direct evaluation of renogram leads to generation of parameters that have no physiological interpretation. the configuration of renogram is very much dependent upon the rate at which radiopharmaceutical...
فرض کنید $ r $ و $ s $ دو حلقه و $ {}_sc_r $ یک دو مدول شبه دوگان باشد. در این پایان نامه ما رابطه ی بین $ g_{c} $-مرابطه با $ c $-مرابطه و هم چنین رابطه ی بین تحلیل $ g_{c} $-تصویری و تحلیل تصویری از یک مدول را بررسی می کنیم. به علاوه نشان می دهیم که اگر egin{center} $ mathbf{g}^{ullet} : cdots ightarrow g_{1} ightarrow g_{0} ightarrow g^{0} ightarrow g^{1} ightarrow cdots$ end{center}...
Doppler planet searches have discovered that giant planets follow orbits with a wide range of orbital eccentricities, revolutionizing theories of planet formation. The discovery of hundreds of exoplanet candidates by NASA’s Kepler mission enables astronomers to characterize the eccentricity distribution of small exoplanets. Measuring the eccentricity of individual planets is only practical in f...
Context. An important benchmark for current observational techniques and theoretical modeling of exoplanet atmospheres is the transit of Venus (ToV). Stellar activity and, in particular, convection-related surface structures, potentially cause fluctuations that can affect the transit light curves. Surface convection simulations can help interpreting the ToV as well as other transits outside our...
background: to determine the colon transit time (ctt) in patients complaining of functional constipation and to evaluate the correlation between abnormal transit times and the types of constipation and the correlation with age and sex. materials and methods: the signs and symptoms of 84 patients with infrequent or difficult defecation, 33 males and 51 females, with a median age of 33.7 were rec...
