The objective of this study is to optimize the river monitoring network in Taizihe River, Northeast China. The situation of the network and water characteristics were studied in this work. During this study, water samples were collected once a month during January 2009 - December 2010 from seventeen sites. Futhermore, the 16 monitoring indexes were analyzed in the field and laboratory. The pH v...

The upflow microbial fuel cell (UMFC) was developed to generate electricity while simultaneously treating wastewater. During a five-month period of feeding a sucrose solution as the electron donor, the UMFC continuously generated electricity with a maximum power density of 170 mW/m2. To achieve this power density, the artificial electron-mediator hexacyanoferrate was required in the cathode cha...

A Bayesian approach was applied to river water quality modeling (WQM) for load and parameter estimation. A distributed-source model (DSM) was used as the basic model to support load reduction and effective water quality management in the Hun-Taizi River system, northeastern China. Water quality was surveyed at 18 sites weekly from 1995 to 2004; biological oxygen demand (BOD) and ammonia (NH(4)(...

Ekológia (Bratislava), vol. 33, no. 1, p. 60–66, 2014. The first part of this investigation studied complex nature of chemical oxygen demand (cod) parameter on local and overall effluents, which were obtained from two pulp and paper mills, located i...

Few direct-assessment procedures are designed to identify potential negative reinforcers (e.g., including demands in the escape condition of functional analyses). Two participants were systematically exposed to a series of demands nominated by caregivers as potential negative reinforcers. Sessions ended following the first instance of problem behavior, and a hierarchy of demand aversiveness was...

This paper studies collusion in repeated Bertrand oligopoly when stochastic demand levels for the product of each rm are their private information and are positively correlated. It derives general su cient conditions for e cient collusion through communication and a simple grim-trigger strategy. This analysis is then applied to a model where the demand signal has multiple random components whic...

This paper describes displacement mapping technique that is used in 3D graphics to add detail on the object’s surface. There are various approaches for implementing it that suit different usages. Most common approaches are explained and shortcomings for each are listed. An adaptive view dependant tessellation algorithm is looked at more closely and some hardware related issues are also discusse...
