Abstract:
A hand-held near infrared (NIR) spectrophotometer combined with a similarity index (SI) method was evaluated to identify meat samples sourced from exotic and traditional meat species. Fresh meat cuts of lamb (Ovis aries), emu (Dromaius novaehollandiae), camel (Camelus dromedarius), and beef (Bos taurus) sourced from a commercial abattoir were used and analyzed using a hand-held NIR spectrophotometer. The NIR spectra of the commercial and exotic meat samples were analyzed using principal component analysis (PCA), linear discriminant analysis (LDA), and a similarity index (SI). The overall accur

The volume of data-generating today in every domain in form of digital is enormous and same time acquiring such information for various analyses and decisions is growing in every field. So, it is significant to integrate the related information based on their similarity. But the existing integration techniques are usually having processing and time complexity and even having constraints in interconnecting multiple data sources. Many of these sources of information come from a variety of sources. Due to

Abstract:
Snow water equivalent (SWE), the amount of water generated when a snowpack melts, has been used to study the impacts of climate change on the cryosphere processes and snow cover dynamics during the winter season. In most analyses, high-temporal-resolution SWE and SD data are aggregated into monthly and yearly averages to detect and characterize changes. Aggregating snow measurements, however, can magnify the modifiable aerial unit problem, resulting in differing snow trends at different temporal resolutions. Time series analysis of gridded SWE data holds the potential to unravel the impacts of

Abstract:
Hesitancy and uncertainty features of experts are common in the decision-making process, especially for the project management events. To solve this problem, a novel similarity-based decision-making approach is put forward, as well as an application to the hydraulic engineering project management. Several experts, who are invited in the decision-making process, are suggested to adopt hesitant fuzzy preference relations (HFPRs) to show their evaluations. To measure the similarity degree of experts, a novel integrated similarity index (SI) is given combining the alternative ranking-based similar

Abstract:
Change management involves a set of changes within entities that poses a risk to the stability of the entity. Similarity index helps to analyze and prioritize the changes, but it provides inaccurate results due to non-consideration of type of similarity. Existing types of similarities also lack accuracy in comparing the versions due to history slicing in case of renaming or shifting. Thus, the proposed combination of fuzzy and hybrid techniques uses modified similarity index that helps in prioritizing the changes in the entities based on the proposed nominal similarity classifications.

Abstract:
The structural index (SI) is based on the concept of Euler homogeneity, a description of scaling behavior. It has found wide use in potential-field depth estimation and is a constant integer for simple sources with single singularities (points, lines, thin-bed faults, sheet edges, infinite contacts). For these cases, the SI is identical to the index of a simple power-law field fall-off with distance. The simple Euler formulation is only strictly correct for such simple sources and integer SI values. The widespread use of the simple Euler method on more complex structures, using fractional SI v

Falls in older adults can cause disabling health even though falls are largely preventable. A combination of fall risk factors can be modified or predicted to minimize devastating complications. However, clinical balance assessment tools often have contradictory results since fall risks are individualized and multifactorial. The assessment tools are often practically limited to detecting sensitive changes between older adults with and without balance deficits. Recently, a similarity index (SI) has been developed to predict fall risks based on kinematic data during gait. The combined limb motio

Abstract:
In spark ignition (SI) engines, high efficiencies are typically obtained near limits of stable operation which may result in high cycle-to-cycle variations (CCV). Traditional computational fluid dynamics (CFD) tools like Reynolds-averaged Navier-Stokes simulations (RANS) may not predict the CCV in engines. Higher fidelity CFD tools like large-eddy simulations (LES) have been shown to capture these CCV. In this paper, LES of a motored transparent combustion chamber (TCC) engine is performed to simulate the CCV introduced during the gas exchange process. A grid convergence study is performed, an

Abstract Most kinetic scale inhibitors behave similarly in mild to severe scale risks by extending induction time. Induction time refers to the time from equilibrium shifting into supersaturation occurs until detectable scale forms. The higher a scale inhibitor dosage, the longer an induction time. However, in this study, different inhibition behaviors were observed under different scale inhibitor treatments in extremely severe barium sulfate (i.e., barite) conditions, with an associated saturation index (SI) of 2.79.
