Several previously unnoticed patterns with historical implications for the late Iron Age and the Persian and Hellenistic periods are discussed. The accompanying typology developed for the purpose of this research should further facilitate excavators' ability to cross-reference new finds against parallels in the existing corpus to date.

The goal of this study was to evaluate the emissions and fuel consumption impacts of electric-hybrid excavators using a Portable Emissions Measurement System (PEMS)-based methodology. In this study, three hybrid and four conventional excavators were studied for both real world activity patterns and tailpipe emissions.

Construction equipments usually constitute a major portion 10-35% of the total cost in a building construction project. For having the best result in profit for a construction industry choosing the best alternative for obtaining equipment is one of the most important issues. The identification of the factors that effect on equipment selection

Jan 31, 2014 · "Low-alloy quench and tempered (Q&T) steel plates having yield strength of a minimum of 670 MPa are used extensively for the fabrication of impellers, penstocks, excavators, dumpers, and raw material handling devices, where welding is an important and probably most economic and productive process of joining.

ABSTRACT In this paper, a new robust adaptive neural fuzzy controller (RANFC) for manipulators is proposed. The proposed controller uses the fuzzy logic inverse dynamic model output (approximated torques/forces) as a model-based control term; a decentralized PID controller as a feedback term to enhance closed-loop stability and improve transient performance; and multi-layer feedforward neural

It has been verified by field tests that the developed STATCOM follows rapid fluctuations in nearly symmetrical lagging and leading VAr consumption of electric excavators, resulting in nearly unity pf on monthly basis, and the harmonic current spectra in the lines of CSC-STATCOM at the point of common coupling comply with IEEE Std. 519-1992.

The paper proposes an approach for obtaining optimal positioning of excavators in digging processes. First, constraints and assumptions regarding excavator and dig geometries are stated. The excavator work space is correlated to its kinematics and the geometric locus of optimal points – points that correspond to maximal length of boom-arm

Cremated remains have historically been a neglected area of archaeological evidence, with many early excavators discarding remains with little attempt at formal analysis; until recently, they were undervalued as a resource and their potential under-explored.

The paper shows an investigation of the accuracy and reliability of industrially available payload estimation methods in construction machinery, specifically hydraulic excavators. "Payload" refers to the weight exerted at the operating end (bucket) of the working arm of an excavator due to the amount of material in the bucket.

The working environment of the construction industry becomes harder and the operator qualities go lower. Moreover NFC (negative flow control) is one of the pump control types of the hydro-mechanical excavator, of which discharged flow rate of the pump is controlled by the pressure developed at the orifice of center-bypass line in a main control valve.

This is the case in the exploitation of multi-layer (zebra-like) lignite deposits, which are common in Greece. In this paper, a multi-layer lignite mine with a continuous excavation system consisting of seven bucket wheel excavators of various types and a network of 16 km of belt conveyors is simulated using the ARENA™ simulation software.

Although Cretan excavators during the late nineteenth century received academic degrees in literature, medicine or law, their systematic excavations aimed towards professionalizing the field. Excavators were at the intersection of Cretan politics, education, and archaeology, as well as stewards of the past.
