We obtain and study new Φ-entropy inequalities for diffusion semigroups, with Poincaré or logarithmic Sobolev inequalities as particular cases. From this study we derive the asymptotic behaviour of a large class of linear Fokker-Plank type equations under simple conditions, widely extending previous results. Nonlinear diffusion equations are also studied by means of these inequalities. The Γ2 c...
در سراسر این پایان نامه r را یک حلقه نوتری جابجایی و یکدار و m را یک مدول با تولید متناهی روی r در نظر گرفته شده است. این پایان امه در سه فصل نوشته شده که در فصل اول تمامی تعاریف قضایایی را که لازم خواهند بود آورده شده است. فصل دوم و سوم براساس دو مقاله زیر تهیه شده است.فصل دو براساس مقاله زیر:injective modules and linear growth of primary decompositions که توسط r.y.sharp در...
Energy consumption in commercial and educational buildings is impacted by group activities such as meetings, workshops, classes and exams, and can be reduced by scheduling these activities to take place at times and locations that are favorable from an energy standpoint. This paper improves on the effectiveness of energy-aware room-booking and occupancy scheduling approaches, by allowing the sc...
these days, all department stores make an effort to provide their clients with valuable products in order to project the best image for them. as a result, clients’ comprehension risk will decrease and they will be more willing to repurchase. having a good image is really important for the department stores because it makes an impression on clients’ comprehension of both quality and risk. consid...
In this paper, several equations were employed to estimate global solar radiation from sunshine hours for a meteorological station in Nigde, Turkey, using only the relative duration of sunshine. These equations included the original Angstrom-Prescott linear regression and modified functions (quadratic, logarithmic and exponential functions). Estimated values were compared with measured values i...
We explore cosmological perturbations in a modified Gauss-Bonnet f(G) gravity, using 1+3 covariant formalism. In such formalism, we define gradient variables to get perturbed linear evolution equations. transform these equations into ordinary differential spherical harmonic decomposition method. The obtained are time-dependent and then transformed redshift dependent. After transformations, anal...
the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...
