results according to the study results, noise levels in a co2 plant’s house and control room ranged from 88 to 102 db and 79 to 82 db (a), respectively. in order to reduce the amount of emitted noise in the co2 plant house and control room, a noise control plan was implemented in each part of the facility; it was met with effective results. conclusions the findings of this investigation have cl...

We comprehensively analyze the performance of a type of optical rotation (OR) polarimeter, which has been designed from the outset to fit the special requirements of two major applications: general chiral detection during the separation of optical isomers by high-pressure liquid chromatography systems in the pharmaceutical industry, and monitoring of glucose in the interstitial fluid of diabeti...

As devices and operating voltages are scaled down, future circuits will be plagued by higher soft error rates, reduced noise margins and defective devices. A key challenge for the future is retaining high reliability in the presence of faulty devices and noise. Probabilistic computing offers one possible approach. In this paper we describe our approach for mapping circuits onto CMOS using princ...

The results of noise immunity studies signal structures based on signals with orthogonal frequency multiplexing (OFDM signals) for multipath propagation and in the presence additive spectrum-focused interference (SFI) are presented. It has been shown that algorithms receiving these constructs SFI compensation, essence which is non-linear processing input implementations by limiting or switching...

Carbon fiber composites are commonly used in aerospace and other fields due to their excellent properties, fatigue damage will occur the process of service. Damage imaging can be performed using probability methods obtain condition carbon composites. At present, factor algorithm has low contrast poor anti-noise performance, which leads artifacts misjudgment damaged area. Therefore, this paper p...

This paper presents a block-based ciphering scheme that employs the 2D discretized chaotic Standard map (CSM) in three different operation modes. The employed modes include electronic codebook (ECB), output feedback (OFB) and cipher block chaining (CBC) In presented CSM with OFB CBC, initiation vector (IV) is as primary secret key. CBC has two merits. first merit ability of ECB, to encipher ima...

garlic and onions as dietary constituents and medicines have been used for many disorders which dates back to the early civilization. it has been shown that different species of allium have immunomodulating effects. in this study, we sought to determine if methanolic and chloroformic extracts of allim fistulosum l. (leek) have any effect on cell-mediated immune response in mice. methanolic and ...

background: cigarette smoking has been linked with the suppression of immune responses and increased susceptibility to numerous infections in humans. tetanus is also a major public health problem in many countries. the aim of the present study was to evaluate the serum levels of anti-tetanus toxin antibodies in c igarette smoking and healthy non-smoking people .   materials and methods: a total...

A fully parallel iterative thinning algorithm called MB2 is presented. It favourably competes with the best known algorithms regarding homotopy, mediality; thickness, rotation invariance and noise immunity, while featuring a speed improvement by a factor two or more owing to a smaller number of operations to perform. MB2 is grounded on a simple physics-based thinning principle that conveys both...

This paper presents a new adaptive algorithm for the online linear and non-linear separation of signals with nonuniform, symmetrical probability distributions. The procedure is based on the interpretation and properties of the vectorial spaces of sources and mixtures, using a multiple linearization in the mixture space. The main characteristics of the procedure are its simplicity, its immunity ...
