In this paper, we investigate the possibility of integrating a binocular stereo vision system and a laser range finder to construct 3-D map for path planning and navigation. Our proposed system is realized by forming the task as an optimization problem of minimizing the alignment error between scanned local map and selected parts of the developing global map. The problem is then solved using th...

Many diffusion-ordered spectroscopy (DOSY) NMR techniques have recently been developed to aid in the deconvolution of complex mixtures. Spectroscopic separation based on chemical and physical properties facilitates the identification of mixture components while eliminating time-consuming separation steps and preserving the chemical environment. One way to improve resolution in such experiments ...

As the classical Gaussian mixture model has some problems of not considering it self’s matching degree of Gaussian density functions, model updating and the background in real video motion detection, made improvements on the three aspects. Optimized Gaussian mixture model’s overall architecture and proposed an improved algorithm according to the analysis of the definition and disadvantages of c...

When a target-speech/masker mixture is processed with the signal-separation technique, ideal binary mask (IBM), intelligibility of target speech is remarkably improved in both normal-hearing listeners and hearing-impaired listeners. Intelligibility of speech can also be improved by filling in speech gaps with un-modulated broadband noise. This study investigated whether intelligibility of targe...

The present work was conducted to find out the effect of biofertilizer formulated with four species of bacteria (two species of Azotobacter and two species of Lysobacter) and zinc sulphate. Field experiments with mustard plant were conducted to study the effectiveness of soil application of zinc sulphate and biofertilizer at 0, 10, 20, 30, 40, 50 days after sowing. Plant height and condition of...

The paper presents the application of the mini-models' method (MM-method) based on n-dimensional simplex for modeling of energy efficiency. The article briefly describes the problem of buildings energy performance. The mini-models method is quite new and is a subject of intensive research. The MM-method is instance-based learning algorithm. In the method, group of points which are used in the m...

We consider polygon and simplex equations, of which the simplest nontrivial examples are pentagon (5-gon) Yang–Baxter (2-simplex), respectively. examine general structure (2n + 1)-gon 2n-simplex equations in direct sums vector spaces. Then, we provide a construction for their solutions, parameterized by elements Grassmannian Gr(n 1, 2n 1).

background and aims: several drugs are being used in treatment of hsv infection in human but still introducing an effective safe drug is desirable. methods: we investigated the inhibitory effect of morphine on replication of hsv in vitro. results: the results indicated that a concentration of up to 200 ug/ml morphine had a limited effect on vero cell viability. at this concentration the growth ...

in order to study the impacts of mechanical (using cultivation), chemical (using herbicides) methods and their integration in controlling broadleaf weeds in sugar beet fields, this experiment was carried out as a randomized complete block design with 4 replications in mahidasht-kermanshah in 2006.  in this experiment, 9 different treatments consisting a mixture of post-emergence herbicides phen...

The processing of odour mixtures by young organisms is poorly understood. Recently, the perception of an AB mixture, known to engage configural perception in adult humans, was suggested also to be partially configural in newborn rabbits. In particular, pups did not respond to AB after they had learned A or B. However, two alternative hypotheses might be suggested to explain this result: the pre...
