Fault tolerance in reversible logic circuits and quantum cost optimization

Article in Press

Energy dissipation has a prominent factor for the very large scale integrated circuit (VLSI). The reversible logic-based circuit was capable to compute the logic without energy dissipation. Accordingly, reversible circuits are an emerging domain of research based on the low value of energy dissipation. At nano-level design, the critical factor in the logic computing paradigm is the fault. The proposed methodology of fault...

Effect of variation of different additives on some selected properties of silica sand mould for aluminium castings

Article in Press

The quality of castings in a green sand mould is influenced significantly by its properties, such as green compressive strength, shear strength, shatter index, compatibility, moisture content, permeability and others which depend on input parameters. Usually, the aforementioned properties of a particular casting differ due to variation in composition of the moulding sand mixtures, sand grain shape and size, bonding...

Vertical Accuracy Evaluation of Satellite Digital Elevation Models in Addis Ababa, Ethiopia

Article in Press

Digital elevation models (DEMs) of having various cell sizes, which can take place in the form of digital surface models (DSMs) or digital terrain models (DTMs), are extensively used as indispensable geospatial information sources for various remote sensing applications and for many engineering projects. DEMs of having a definite cell size is freely available on the internet in different world areas. In spite of this, the...

Modeling and experimental validation of drying processus of the microalgue Spirulina with consideration deformation and flow mass

Article in Press

The profiles of the material transfer properties in porous products such as Spirulina platensis during drying which characterize their behavior are often determined from different experimental points by destruction of the samples. However, for a long drying time, it’s impossible to slice or cut the sample correctly because of its mechanical strength and friability. It influences the evaluation of product in cylindrical...

Design and Fabrication of Teff Threshing Machine

Article in Press

Teff has the largest value in terms of both production and consumption in Ethiopia and the value of the commercial surplus of teff is second next to coffee. The traditional way of threshing and winnowing, leads to contamination of grains with foreign matter (pebbles, dirt, and cow dung) and loss of grains due to the foreign matter dropping in to grains and the wind blowing grains away with chaff. This design helps to find...

A Features Fusion Approach for Automatic Pollen Recognition

Article in Press

In microscopy image analysis, images of pollen are particularly difficult to analyze automatically. The major reason of this difficulty emerges from the complex nature of the pollen, which presents great variability and similarities between classes and even on the same classThis paperpropose a feature selection methodology with dimensionality reduction for pollen image classification. First, we extracted five descriptors...

A STUDY ON PRODUCTION OF ANHYDROUS ETHANOL FROM ETHANOL-WATER AZEOTROPIC CONCENTRATION USING PRESSURE SWING ADSORPTION (PSA) PROCESS ON ZEOLITE CATALYST

Article in Press

The demand for pure ethanol has become paramount for its various applications in biofuels and preparation of industrial chemicals, food and pharmaceutical products. Pressure Swing Adsorption (PSA) has proven to be an effective process and a more economical method for separating the azeotropic concentration of ethanol-water (95% ethanol, 5% water) than distillation. The modeling of PSA of ethanol-water azeotropic...
