Image analysis techniques were developed and applied to quantify the process of anaerobic granulation in an expanded granular sludge blanket reactor (EGSB) fed with a synthetic substrate based on glucose [60-30% COD (chemical oxygen demand)] and volatile fatty acids (40-70% COD) over 376 days. In a first operation period that lasted 177 days, the aggregation of dispersed sludge was quantitative...

A temporal database is essential to applications dealing with time-varying data [11], such as trend analysis and prediction in decision support systems, version management in computer aided designs, medical record management, and data warehousing. In this regard, a temporal database system is used to store and query time-varying information. There has been extensive research on temporal databas...

Two-stage decomposition-dynamic programming aggregation method has been first proposed and introduced to solve the mathematical model of daily optimal operation for parallel pumping stations with adjustable-blade units. Taking minimal daily electricity cost of single pump station as objective function, the water quantity pumped by each station as coordinated variable, by means of the type of th...

In view of the high incidence of thromboembolic complications after the insertion of cardiac valve prostheses, platelet adhesiveness and aggregation was measured in whole blood before, during, and for several days after this operation in 10 patients. Cardiopulmonary bypass resulted in a profound decrease in the platelet count, in the number of adhesive platelets, and in platelet aggregation. Th...

Heat causes protein misfolding and aggregation and, in eukaryotic cells, triggers aggregation of proteins and RNA into stress granules. We have carried out extensive proteomic studies to quantify heat-triggered aggregation and subsequent disaggregation in budding yeast, identifying >170 endogenous proteins aggregating within minutes of heat shock in multiple subcellular compartments. We demonst...

Wireless sensor network (WSN) is an important part of the Internet of Things (IoT) and technical support for ubiquitous communication. Data aggregation technology reduces the network traffic overhead and extends the effective working time of the network, but the continued operation of the wireless sensor networks will increase the probability of the aggregation node being captured and probabili...

In the calculation of economic aggregates it is often necessary to compute the value of these aggregates in some relevant subgroups as well as for the whole data. A method of calculation is said to be consistent in aggregation if it gives the same result regardless of whether it is applied directly to the whole data or to subaggregates calculated using the same method. The property has been wel...

Smart grid is a combination of traditional power system engineering and information communication technology. provides users with convenient services through real-time data updates. Multi-dimensional aggregation can be more flexible for statistical analysis electricity information. However, most the existing multi-dimensional schemes require participation trusted third party do not support faul...

Optimization of process planning is considered as the key technology for computer-aided process planning which is a rather complex and difficult procedure. A good process plan of a part is built up based on two elements: (1) the optimized sequence of the operations of the part; and (2) the optimized selection of the machine, cutting tool and Tool Access Direction (TAD) for each operation. In th...
