the feasibility of kaolinite used as a low-cost adsorbent for the removal of pb(ii), zn(ii) and cu(ii) from aqueous solutions was investigated. during the removal process, batch technique was used, and the effects of heavy metal concentration and contact time on adsorption efficiency at ph of 4.5, under a constant temperature of 20?1 ?c were studied. the experimental results were analyzed using...

A batch process is a discontinuous and concurrent process which is suitable for multi-product, small-sized production. The distinctive feature of a batch process is that various decision making processes, such as scheduling, design, operation, etc. are strongly connected with each other. Interaction among these processes is necessary to dynamically and flexibly cope with a variety of unplanned ...

Gradient descent is the workhorse of deep neural networks. has disadvantage slow convergence. The famous way to overcome convergence use momentum. Momentum effectively increases learning factor gradient descent. Recently, many approaches have been proposed control momentum for better optimization towards global minima, such as Adam, diffGrad, and AdaBelief. Adam decreases by dividing it with sq...

Batch verification can provide large computational savings when multiple signatures are verified together. Recently, some batch verifying signature schemes have been proposed from bilinear pairings. In this paper, we show that an attacker can cheat a verifier to accept invalid signatures in these batch verifying schemes. We also show that randomized batch verification technique can be used to a...

A simultaneous flow-injection analysis (FIA) manifold that could analyse three ions from a single injection was designed, constructed, calibrated and used successfully to analyse Li(+), Na(+) and K(+). This FIA method was 10 times faster than the batch technique. The sample volume required was a fraction of about 1/110 to 1/75 that of the batch technique. The outputs were quite reproducible and...

In this work, we investigate Batch Normalization technique and propose its probabilistic interpretation. We propose a probabilistic model and show that Batch Normalization maximazes the lower bound of its marginalized log-likelihood. Then, according to the new probabilistic model, we design an algorithm which acts consistently during train and test. However, inference becomes computationally in...

The batch is an important technique for delivering video over Internet or VoD. It is a key method to improve effect for video multicast. In this paper, we research the batch strategy of proxy cache for streaming media using dynamic cache, proposed the three kind of cache algorithm for proxy cache: window batch, size batch, efficient batch. These methods increased the length of batch, solved the...

Abstract Passive radar (PR) systems need to detect the presence of a target response, which is many orders magnitude weaker than clutter (direct signal and multipath). Indeed, cancellation key stage within PR processing scheme. One most effective techniques in this field using CLEAN approach. In paper, batch-based technique based on GMP FFT has been proposed, can speed up computational have bet...
