This study presents a repetitive group sampling plan and a Multiple dependent state sampling plan based on the EWMA (exponentially weighted moving average) yield index for product acceptance. The proposed plans utilize the current and previous information through EWMA statistic to reach a decision of lot sentencing. A non-linear optimization model is developed to determine the plan parameters of the proposed plans for various speci, ed conditions. The performance of the proposed plans over several existing sampling plans is analyzed, showing that the proposed plans are e, cient in reducing the sample size for lot sentencing. For industrial application, a real example is given to demonstrate the implementation of the proposed plans.

Acceptance sampling models have been widely applied in companies for evaluation the raw material as well as the final products. Meanwhile, process capability indices (PCIs) have been used in various industrial environments as capability measures that are obtained based on process departure from a target, process yield, process consistency and process loss. In this research, first a repetitive group sampling (RGS) plan based on process capability index is developed for variables inspection. Then the optimal parameters of proposed RGS plan are determined and also a new Multiple dependent state (MDS) sampling plan, a double sampling plan (DSP) and a sampling plan for resubmitted lots are developed and finally, a comparison study is carried out between the proposed sampling plans and the results are elaborated.

In this paper, we deal with the state-dependent nonconvex sweeping process motivated through quasi-variational inequalities arising in the evolution of sandpiles, quasistatic evolution problems with friction, micromechanical damage models for iron materials. We prove the existence of absolutely continuous solution for the problem in presence of a perturbation, that is an external force applied on the system. The perturbation considered here is general and take the form of a sum of a single-valued Carath\'eodory mapping and a set-valued unbounded mapping.

In the present study, the effects of morphine sensitization on morphine-induced impairment of memory formation and the state-dependent retrieval of a passive avoidance task learned under morphine influence have been investigated in mice. Pre-training administration of morphine (0.5, 2.5 and 5 mg/kg) dose dependently suppressed the learning of one-trial passive avoidance task. Pre-test administration of morphine (0.5, 2.5 and 5 mg/kg) induced state-dependent retrieval of the memory acquired under pre-training morphine influence which these effects of morphine is named state-dependent learning. The inhibitory effect of morphine (5 mg/kg) on memory formation was significantly antagonized by pretreatment administration of naloxone (0.025, 0.5 and 1 mg/kg) before the pre-training morphine. The pre-test administration of naloxone dose dependently inhibited the restoration induced by morphine (5 mg/kg). Amnesia induced by pre-training morphine significantly inhibited in morphine-sensitized mice, which had previously received once daily injections of morphine (20 and 30 mg/kg, s.c.) for 3 days. Morphine sensitization did not affect on morphine state-dependent memory of passive avoidance. The inhibition of morphine-induced amnesia in morphine-sensitized mice suppressed by once daily injections of naloxone (0.5, 1 and 2 mg/kg) 30 min prior to s.c. injection of morphine (20 mg/kg/day for 3 days). These results suggest that morphine sensitization affect the impairment of memory formation, but not the facilitation of retrieval induced by morphine.
