II. The denial of strict psychophysical laws would not undermine the claim that mental events are causally efficacious. § The three premisses from which AM is derived: (1) that mental events are causally related to physical events (2) that singular causal relations are backed by strict laws (3) that there are no strict psycho-physical laws ⇒ AM + P § "supervenience" ___ a predicate p is superve...

In this study, we introduce a new two-way relay channel and obtain an inner bound and an outer bound for the discrete and memoryless multiple access relay channels with receiver-source feedback via two-way relay channel in which end nodes exchange signals by a relay node. And we extend these results to the Gaussian case. By numerical computing, we show that our inner bound is the same with o...

effect of static magnetic field (smf) on plants is a matter of debate. in the present study plausible useful effects of smf on wheat plant (triticum aestivum l.) via improvement of antioxidant system and iron/ferritin fortification were evaluated. the plants were cultivated in pots and in their reproductive stages were treated with or without a 30 mt smf for 4 days, each 5h. the activity of ant...

in this paper, the direct extrusion process of bimetallic rods in conical dies is analyzed by an improved upper bound method. the deformation zone is subdivided into six smaller zones and by considering a non-spherical entrance boundary to the deformation zone, a velocity field is presented which is different from velocity fields employed in previous studies. the total power consumption of the ...

we consider online scheduling of jobs with speci c release time on m identical machines. each job has a weight and a size; the goal is maximizing total weight of completed jobs. at release time of a job it must immediately be scheduled on a machine or it will be rejected. it is also allowed during execution of a job to preempt it; however, it will be lost and only weight of completed jobs contr...

air defense is a crucial area for all naval combat systems. in this study, we consider a warship equipped with an air-defense weapon that targets incoming threats using surface-to-air missiles. we define the weapon scheduling problem as the optimal scheduling of a set of surface-to-air missiles of a warship to a set of attacking air threats. the optimal scheduling of the weapon results in an in...

We analyze the validity of the generalized covariant entropy bound near the apparent horizon of isotropic expanding cosmological models. We encounter violations of the bound for cosmic times smaller than a threshold. By introducing an infrared cutoff we are able to mantain the bound for a radiation dominated universe. We study different physical mechanisms to restore the bound, as a non-additiv...

heuristics are often used to provide solutions for flow shop scheduling problems.the performance of a heuristic is usually judged by comparing solutions and run times on test cases.this investigation proposes an analytical alternative ,called asymptotic convergence ,which tests the convergence of the heuristic to a lower bound as problem size grows. the test is a stronger variation of worst cas...

ناحیه ظرفیت برای انتقال اطلاعات کلاسیک بر روی کانال های کوانتومی multiple acsses و همچنین انتقال اطلاعات کلاسیکی بصورت امن بر روی کانال های کوانتومی نقطه به نقطه، قبلاً محاسبه گردیده است. در این کار با استفاده از اثبات قضیه ظرفیت اطلاعات کلاسیک و نیز استفاده از قضیه اپراتورهای chernoff bound، ناحیه ظرفیت جدیدی جهت انتقال امن اطلاعات کلاسیک برروی کانال های کوانتومی multiple acsses با دو فرستنده و...
