in this work, an unstructured-type mathematical model was developed to simulatecadmium (cd2+) removal by desulfovibrio alaskensis 6sr, which is a recently described sulfatereducing bacterium, whose capacity for removing heavy metals are being studied. three processesare considered in the model: 1) the sulfate reduction process, 2) the consumption of lactate ascarbon source, and 3) the metal rem...

A method has been developed for preparing load models for power flow and stability. The load modeling (LOADMOD) computer software transforms data on load class mix, composition, and characteristics into the from required for commonly–used power flow and transient stability simulation programs. Typical default data have been developed for load composition and characteristics. This paper defines ...

Pervasive context-aware computing, is one of the topics that received particular attention from researchers. The context, itself is an important notion explored in many works discussing its: acquisition, definition, modelling, reasoning and more. Given the permanent evolution of context-aware systems, context modeling is still a complex task, due to the lack of an adequate, dynamic, formal and ...

A hierarchical framework is proposed to address the issues of modeling different type of words in keyword spotting (KWS). Keyword models are built at various levels according to the availability of training set resources for each individual word. The proposed approach improves the performance of KWS even when no training speech is available for the keywords. It also suggests an easier way to co...

Reconfigurable networked systems have often been developed via dynamically deployed software components that are executing on top of interconnected heterogenous hardware nodes. The challenges resulting from the complexity of those systems have been traditionally mitigated by creative ad-hoc solutions supported by domain specific modeling frameworks and methodologies. Targeting that deficiency, ...

State-of-the-art meta-model based technologies are facing increasing pressure under new challenges originating from practical industrial applications. Dynamic Multi-Layer Algebra (DMLA) is a novel generic modeling approach that intends to meet these challenges by combining multi-level meta-modeling and validated instantiation. This paper describes the core ideas and techniques that have been ap...

Among all FACTS devices, the unified power flow controller (UPFC) is considered to be the most versatile device. This is due to its capability to control all the transmission system parameters (impedance, voltage magnitude, and phase angle). With the growing interest in UPFC, the attention to develop a mathematical model has increased. Several models were introduced for UPFC in literature for d...

Sentence compression is a valuable task in the framework of text summarization. In previous works, the sentence is reduced by removing redundant words or phrases from original sentence and tries to remain information. In this paper, we propose a new method that used Grid Model and dynamic programming to calculate n-grams for generating the best sentence compression. These reduced sentences are ...
