This paper applies the data mining techniques in the area of data cleaning as effective in discovering Constant Conditional Functional Dependencies(CCFDs) from relational databases . These CCFDs are used as business rules for context dependent data validations. Conditional Functional Dependencies(CFDs) are an extension of Functional dependencies(FDs) which captures the consistency of data by su...

In the communication mechanism of co-time co-frequency full-duplex (CCFD), digital selfinterference cancellation (SIC) is used for suppressing residual self-interference (SI) after antenna and radio frequency (RF) SICs, as well as low-power multipath SI. In this study, the CCFD LTE verification experiment is presented, which adopts digital SIC with the SI signal reconstructed in frequency domai...

In this study, granulated sludge synthesized in a sequence batch reactor (SBR) and then granulated sludge was transferred to continuous feeding and intermittent discharge (CFID) bioreactor. Two independent variables (air flow rate and hydraulic retention time (HRT)) were considered to optimize the process. Subsequently, long term performance (150 days) of the bioreactor was assessed by monitori...

A statistical model was developed in this study to describe bioethanol production through a batch fermentation process of sugarcane molasses by locally isolated Saccharomyces cerevisiae Y-39. Response surface methodology RSM based on central composite face centered design CCFD was employed to statistically evaluate and optimize the conditions for maximum bioethanol production and study the sign...

An up-flow anaerobic sludge fixed film (UASFF) bioreactor was used to treat the pretreated palm oil mill effluent (POME). In physical pretreatment, POME was pre-settled for 2 h and the supernatant was fed into the reactor. In chemical pretreatment, optimum dosages of cationic and anionic polymers were used. Experiments of pretreated POME digestion were conducted based on a central composite fac...

Adsorption of cationic dye crystal violet (CV) onto a modified walnut shell (WS) adsorbent was investigated. Combined treatment WS using urea and sodium dodecylsulfate (SDS) carried out. Surface modification adsorbents confirmed by FTIR analysis, pHpzc measurements, elemental SEM-EDX analysis. In order to optimize the adsorption conditions, effect solution pH, dose CV concentration studied mean...

The Helmholtz problem in the 3{dimensional space is hard to solve numerically due to its huge problem size and poorly{conditioned algebraic system obtained by discretization schemes. In this paper, we suggest a nonoverlapping domain decomposition iterative procedure for solving the problem by the cell{centered nite diierence (CCFD) methods. We introduce a modiied Robin interface boundary operat...

IMplicit Pressure Explicit Saturation (IMPES) scheme with treating buoyancy and capillary forces is used to solve the two-phase water-CO2 flow problem. In most of the previous studies of the two-phase flow, the buoyancy force term was ignored; however, in the case of liquidgas systems such as water-CO2, the gravity term is very important to express the buoyancy effect. In this paper, we present...

We consider a multigrid algorithm (MG) for the cell centered finite difference scheme (CCFD) on general triangular meshes using a new prolongation operator. This prolongation is designed to solve the diffusion equation with strongly discontinuous coefficient as well as with smooth one. We compare our new prolongation with the natural injection and the weighted operator in Kwak, Kwon, and Lee (A...

This paper presents a design scheme of wire-line telephone system using self-interference (SI) cancellation technology in co-frequency co-time full-duplex (CCFD) to realize absolute secure communication at the physical layer. can hide target signal by skillfully releasing high-power artificial noise whole link receiving node, and then make use receiver’s knowledge SI achieve high dB with help a...
