High performance sub-volt current mirror are widely used in building mixed-mode low power VLSI systems. The performance of current mirror is decided by its key parameters which includes large operating range, low input compliance voltage, wide swing, large bandwidth along with very low input and very high output resistances. In this paper, a design...

Ontology is the fundamental representation used to link the various concepts of each field. It is widely utilized in the agricultural sector for the classification and expansion of new data and understanding. Besides this, the agriculture ontology enables optimization of feature weights to exact text from the source. However, the conventional metho...

A fluid dynamics numerical simulation is carried to study the gust characteristics produced downstream of a pair of sinusoidally pitching two-dimensional thin foils with a certain lateral spacing and placed in a freestream flow. The flow was simulated for Reynolds number (Re) = 1.6 × 105, the airfoil pitching angle = 6.9°, and a range of reduced fr...

Recognizing the person from a sample of their voice print or speech samples is known as Speaker recognition. It is an emerging technology, in recent years machine learning (ML) based classification schemes have been observed as one kind of alternate solution for speaker recognition. In this paper adaptive boosting (AdaBoost) combined with a powerfu...

In the present study, performance of the fabricated evacuated U-tube solar collector integrated parabolic reflector (EUSCIPR) and conventional evacuated U-tube solar collector (CEUSC) are analysed experimentally. With reference to humid climatic conditions, a 3D model is developed for comparing the thermal performance of EUSCIPR with a CEUSC. Devel...

This article examines the stability of retaining walls with relief shelves compared to the conventional cantilever wall using limit analysis integrating with the finite element method. The performance of such walls subjected to an incremental static uniformly distributed surcharge loading on the backfill surface is accessed in the terms of the magn...

In an ideal conditions, three-way catalytic converters have a structure that will convert almost all of the harmful exhaust emissions. However, these conditions are not valid for cold start and idle conditions. Especially in cold weather, people wait for a while at the idle speed even though it is not a good way to warm up the engine. In this perio...

Air plasma sprayed (APS) 7weight percent yttria stabilized zirconia (7YSZ) typical thermal barrier coatings are commonly used in aero engine components to protect against thermal fatigue, corrosion, erosion, corrosion-erosion and oxidation phenomenon. In spite of extensive industrial application of 7YSZ coatings, very few works are there on erosion...

Despite the considerable advantages of SPSW, there were some shortcomings concerning the system. Needing huge columns surrounding the infill plate has been the main dilemma of the SPSW system. This problem will be due to high imposed stresses to columns by the infill plate. Perforated SPSW has shown a capable method among the proposed methods to re...
