An Inference Engine for Gene Network Determination by Means of Optical Array Logic
نویسندگان
چکیده
Recent progress in DNA micro-array techniques enables us to obtain a massive amount of gene expression profiles simultaneously. Using the expression profiles we infer a gene network hiding the obtained data. Although several inference methods have been presented, most of them are insufficient in terms of reliability and processing time [1]. To overcome the problem, we develop an inference engine with SIMD (Single-Instruction Multi-Data stream) parallel operations based on optical array logic (OAL). Then we describe the algorithm with HDL (Hardware Description Language) and construct a prototype of the inference engine on an FPGA (Field Programmable Gate Array) device.

Adaptive neuro-fuzzy inference system (ANFIS) applied for spectrophotometric determination of fluoxetine and sertraline in pharmaceutical formulations and biological fluid
The UV-spectrophotometric method of analysis was proposed for simultaneous determination of fluoxetine (FLX) and sertraline (SRT). Considering the strong spectral overlap between UV-Vis spectra of these compounds, a previous separation should be carried out in order to determine them by conventional spectrophotometric techniques. Here, full-spectrum multivariate calibrations adaptive neuro-fuzz...
متن کاملA Comparative Study of the Neural Network, Fuzzy Logic, and Nero-fuzzy Systems in Seismic Reservoir Characterization: An Example from Arab (Surmeh) Reservoir as an Iranian Gas Field, Persian Gulf Basin
Intelligent reservoir characterization using seismic attributes and hydraulic flow units has a vital role in the description of oil and gas traps. The predicted model allows an accurate understanding of the reservoir quality, especially at the un-cored well location. This study was conducted in two major steps. In the first step, the survey compared different intelligent techniques to discover ...

In this paper, for the first time to our knowledge, we investigate the optical bi-stability in a compact parallel array of micro- ring resonators with 5μm radius, induced by optical nonlinearity. Due to the nature of perfect light confinement, resonance and accumulation process in a ring resonator, optical nonlinear effects, even at small optical power of a few milliwatts in this structure are ...
متن کاملProposal of a Prolog-based Knowledge Wiki
This paper presents a proposal of a knowledge wiki system and describes its prototype implementation. The system design is based on a wiki concept regarding authoring policies and user access, extended with an ability of storing knowledge in addition to the human-readable content. The knowledge is expressed in the Prolog language by means of predicate logic. An inference engine is coupled with ...
