[Purpose] The aim of this study was to verify the effect of sideways treadmill training with and without visual blocking on the balance and gait function of patients with brain lesions. [Subjects] Twenty-four stroke and traumatic brain injury subjects participated in this study. They were divided into two groups: an experimental group (12 subjects) and a control group (12 subjects). [Methods] E...

heavy precipitation plays a significant role in arid and semi-arid regions of iran. in order to understand the effect of blocking high system on rainfalls in northwest iran during 25 - 28 october 2008, meteorological conditions including pressure, wind fields and temperature at multiple levels of the atmosphere were analyzed. sea level pressure, the 1000-500 hpa thickness, perceptible water, re...

since 20th  century, when allergy was defined, an ongoing attempt for discovering the mechanisms underlying it and its treatment began. defining allergens as well as cells such as regulatory t-cells and characterizing the antibodies involved in the pathogenesis (including blocking antibodies) have helped very much towards a better understanding of the immunologic process.however, allergen speci...

Effective approximations are developed for the blocking probability in a general stationary loss model with dependence among successive service times as well as among successive interarrival times by exploiting heavy-traffic limits for the steady-state number of busy servers in the associated infinite-server model with the same arrival and service processes. In addition, a new heavy-traffic app...

Currently, the Immediate reservation (IR) and advance reservation (AR) are the two main reservation mechanisms implemented on large-scale scientific optical networks. We can also provide hybrid IR/AR scenarios. Nonetheless, such scenarios can increase the blocking of IR if no quality-of-service (QoS) policies are considered. A solution could be to quantify such blocking performance is that to i...

Distribution centers are under increasing pressure to adopt material handling systems that offer greater flexibility to improve cycle time and throughput capacity in the transfer of unit loads in their high density storage areas. Autonomous Vehicles-based Storage and Retrieval Systems (AVS/RS), have been shown to hold significant promise in this context. In these systems, loads are transferred ...

This study investigates an optimization-based heuristic for the Robotic Cell Problem. This problem arises in automated cells and is a complex ‡ow shop problem with a single transportation robot and a blocking constraint. We propose an approximate decomposition algorithm. The proposed approach breaks the problem into two scheduling problems that are solved sequentially: a ‡ow shop problem with a...

1. introduction the effect of blocking on iran’s precipitation in numeral way and long-term has not been done yet. however, in some researches based on weak indexes like one-dimension has been implied to iran that in studying many cases we observe lack of blocking event and or their continuation that has been for less than 5 days. this phenomenon in some cases occurs in our country directly and...
