the present study was conducted to investigate the impacts of retrofitted cng vehicles on airpollutant emissions in tehran over a 20 years period using available statistical data, precise automobile tests, data analysis, and leap software. the obtained results revealed an increase in air pollutant emissionsincluding co (equal to 1030.77 thousand tons), nox (equal to 1030.77 thousand tons), thc ...

The Leap Motion opens new possibilities for mapping the various degrees of motion of the human hand with musical expression. The Leap Motion is a computer peripheral released in mid 2013 that uses IR cameras to track hand and finger location with unprecedented accuracy. In this paper, we explore implementations of the device in sound synthesis and effects control. The device is interfaced with ...

The application of Reinforcement Learning (RL) algorithms to learn tasks for robots is often limited by the large dimension of the state space, which may make prohibitive its application on a tabular model. In this paper, we introduce LEAP (Learning Entities Adaptive Partitioning), a model-free learning algorithm that uses overlapping partitions which are dynamically modified to learn near-opti...

The Linear Noise Approximation (LNA) is a continuous approximation of the CME, which improves scalability and is accurate for those reactions satisfying the leap conditions. We formulate a novel stochastic hybrid approximation method for chemical reaction networks based on adaptive partitioning of the species and reactions according to leap conditions into two classes, one solved numerically vi...

Leap protocol offers many security benefits to WSNs. However, with much research it became apparent that LEAP only employs one base station and always assumes that it is trustworthy. It does not consist of defence against hacked or compromised base stations. In this paper, intensive research was undertaken on LEAP protocols, finding out its security drawbacks and limitations. One of the biggest...

In numerically simulating the time evolution of a well-stirred chemically reacting system, the recently introduced “tau-leaping” procedure attempts to accelerate the exact stochastic simulation algorithm by using a special Poisson approximation to leap over sequences of non-critical reaction events. Presented here is an improved procedure for determining the maximum leap size for a specified de...

In the first study designed to compare the LEAP and TEACCH comprehensive treatment models for children with autism spectrum disorders (ASD), researchers have found that preschoolers with ASD make gains during the school year regardless of whether teachers use TEACCH, LEAP, or a high-quality special education model. Previous studies have shown that when children with autism spectrum disorders ha...

We describe an e cient fair queuing scheme, Leap Forward Virtual Clock , that provides endto-end delay bounds almost identical to that of PGPS fair queuing, along with throughput fairness. Our scheme can be implemented with a worst-case time O(log logN ) per packet (inclusive of sorting costs), which improves upon all previously known schemes that achieve guaranteed delay and throughput fairnes...
