Assessment of image similarity is ubiquitous and essential task to a wide range multimedia applications. In this paper we propose a similarity method which aims at providing an image classification scheme using multi-instances based representation of an image. In other words, the similarity measure is defined to be used within two sample sets where each set, which can be defined in an arbitrary metric...
The typical “Green Computing” case studies are discussed. The deployments scenarios based on waste heat modeling and recycling are discussed. The following simplified models to solution of the Boltzmann thermodynamic equations are examined. Taken into account the presented models the approximated estimations regarding to PUE within the computing centers of the cloud and HPC providers can be met.
In recent times, the interaction between process design and control has become the focus of research and development, because not always the best process design features the best dynamic performance, with implications in the controllability of the plant. It is then proposed a simultaneous approach of economic goals and controllability in the early stages of the project design. Recent studies have...
Unquestionably, one of the most important developments in this century has been the avalanche advancement of Integrated Circuits technology incorporating solid state systems into areas never before imagined. Students face special challenges to understand these complex systems using conventional instructional methods. We here present a new pedagogical approach using the Variational Thermodynamic principle...
RNA secondary (2D) structures are essential for cellular processes including protein translation; indeed some RNA viral pathogens use this strategy during replication cycle. Among Flaviviridae family, Hepatitis C Virus (HCV) presents a well experimentally-characterized secondary structure called IRES (Internal Ribosome Entry Site), which could be used as a Viral model for evaluating the accuracy RNA...
Hydrogen production from biomass-derived glycerol can be conducted by different reforming pathways. Thermodynamics analysis in this work presented that aqueous phase reforming (APR) is prior to steam reforming (STR) process with regard to CO level, and methanation should be limited kinetically in APR process to maximize hydrogen generation. Experimental work demonstrated that methanation could be...
Taking Changguang coal as experimental coal type, carrying out the experiment of Q-phase cement clinker co-generated from high-sulfur coal on two-section multiphase reaction test stand and conducting XRD analysis on the mineral composition in co-generation clicker sample, it was found that the major mineral species in compositions of co-generation clinker are 2CaO·SiO2, Q phase and calcium sulphoaluminate...
Four types of double-stage Water-Lithium Bromide absorption heat pump systems were introduced to recover waste heat of about 40°C. Thermodynamic and heat transfer numerical simulation was carried out to predict the performance of these absorption heat pumps. The effects of the driving heat source (steam) input pressure, the waste heat outlet temperature, and the hot water inlet temperature on the...
The mathematical model of the gas turbine performance in the condition of fault is established by using the exergy efficiency, which as a figure of merit of the work potential that based on the second law of thermodynamics. The performance matrix of fault model is derived by using the small deviation method. The exergy efficiency is contrasted with the efficiency, which is the traditional function...
The technique of determining the chemical and phase composition of the emissive material in the process of vacuum thermal treatment. The method is based on the division of the vacuum thermo process into intervals within which the system was considered a quasi-equilibrium. In its turn, determining the structure of equilibrium during each time slice consisted in the determination of such chemical and...
This study examines the performance of a high-temperature solid oxide fuel cell combined with a conventional recuperative gas turbine (GT-SOFC) plant, as well as the irreversibility within the system. Individual models are developed for each component, based on the first and second laws of thermodynamics. The overall system performance is then analyzed by applying thermodynamic laws for the entire...
The need for novel, high performance actuators felt in several fields of robotics, such as assistive or rehabilitative robotics, is not fully satisfied by current actuation means. This fosters an intense research on novel energy transduction methods. In particular, propellant-based chemical actuators, able to directly convert chemical energy into mechanical energy, appear very promising, although...
Structure features of 3Cr17NiMo plastic die steel quenched at 1030??C and tempered at different temperatures have been analyzed by means of optical microscope, transmission election microscope (TEM), X-ray, electron probing analysis (EPA) and microhardness instrument. Semiquantitative analysis on polishing performance was done using interference microscope in order to determine factor influencing...
The effect of temperature on adsorption of reactive blue 19 (RB19) by cross-linked chitosan/oil palm ash composite beads was investigated. Temperature studied from range 30 to 50??C. It was observed that the uptake of this dye increased with increasing in temperature. Results revealed that sorptions of reactive blue 19 (RB19) on cross-linked chitosan/oil palm ash composite beads was endotermic in...
Sustainability issues involving materials processing and manufacturing are still very poorly investigated. This is true in particular for non-energy parts of such systems. Thermodynamics approaches attract an increasing attention due to general applicability and a clear potential to include both quantity and quality aspects of resources utilization, process assessments and metrics selection. One of...
A low energy free-carrier generation appears in nanoscale Si-layered systems. The experimental devices contain a superficial Si nanostratum (3-5 nm thick and tensile strained) formed at the SiO2 /Si heterointerface during a processing including thermal oxidation, ion implantation and suitable thermal treatment. The nanostratum is composed of transformed c-Si. The investigation in the UV range (400...
The photon absorption in solar cells is divided into processes with and without work production. An analogue of the processes without work production is the selective absorption of solar radiation by pigment molecules of plant cells, and an example of processes with work production is the work of chlorophyll molecules in plant photosynthesis. We have called the without work processes photon reemission...
