determination a sequence of extracting ore is one of the most important problems in mine annual production scheduling. production scheduling affects mining performance especially in a poly-metallic open pit mine with considering the imposed operational and physical constraints mandated by high levels of reliability in relation to the obtained actual results. one of the important operational con...

Distributed neural processing creates a binding problem: the representations of the various features of an object are distributed across brain areas but must be associated with, or bound to, the same object. Here we determine the limits that binding imposes on the perception of global form in static flow fields defined by oriented dot pairs. The binding of local orientation signals into global ...

employees’ satisfaction based on their physical environment is an important factor that can improve employees’ performance, job satisfaction, and organizational productivity in office buildings. occupants’ environmental satisfaction are related to 10 different characteristics, including thermal comfort, air quality, lighting, acoustic quality, office layout, workspace furnishing, cleanliness an...

Introducing attentional mechanism in neural network is a powerful concept, and has achieved impressive results in many natural language processing tasks. However, most of the existing models impose attentional distribution on a flat topology, namely the entire input representation sequence. Clearly, any well-formed sentence has its accompanying syntactic tree structure, which is a much rich top...

Range queries seek the objects residing in a constrained region of the data space. An XML range query may impose predicates on the numerical or textual contents of the elements and/or their respective path structures. In order to handle content and structure range queries efficiently, an XML query processing engine needs to incorporate effective indexing and summarization techniques to efficien...

The explosive growing of earth observing data needs to have relative efficient data processing methods. This paper aims at the processing and analysis of large volume of vector field data acquiring from satellite derived, or model assimilation, an approach of fronts extraction from vector field data was proposed. The study is based on the assumption that the distribution of feature vectors for ...

ultrasound-assisted extraction was used to determine the optimum processing conditions and to achieve the maximum extraction yield and viscosity of the gum extracted from quince seed. using response surface methodology (rsm) to design the experiments and adopting the central composite rotatable design (ccrd), the effect of extraction temperature (25-55°c), time (3-10 minutes), and ph (6-8) were...

The component of protein in rice, at 7-9% by weight, is relatively low, but the total amount of rice protein potentially available is significant because the production of rice worldwide, at 380 million tons annually, is huge. Rice proteins are recognized as nutritional, hypoallergenic, and healthy for human consumption, and rice protein products have been in demand in recent years. However, be...

Accurate involuntary personal identification is critical in a variety of applications in our electronically interconnected society. Biometrics, which mentions to identification based on physical or behavioural characteristics, is being progressively adopted to provide positive identification with a high degree of confidence. Among all biometric techniques, fingerprint-based authentication schem...
