Study on the production technology in ancient glass artefacts is one of the interesting subject in the field of archaeological sciences. The aim of this study is to identify the chemical composition and production technology in the glass objects discovered form the underground hand-made architectural complex of Arzanfood, near Hamedan, in western Iran. These objects are including some broken pi...
The study of the archaeological remains of fossil hominins must rely on reconstructions to elucidate the behaviour that may have resulted in particular stone tools and their accumulation. Comparatively, stone tool use among living primates has illuminated behaviours that are also amenable to archaeological examination, permitting direct observations of the behaviour leading to artefacts and the...
Artefacts are noises introduced to an EEG signal by patient’s movements and sources of electric field outside the patient’s body. The artefacts impede a doctor’s expertise and an automatic analysis of the signal. The most common and characteristic kind of artefacts are blinking artefacts. This paper presents a neural based approach to finding artefacts in the signal. The inputs to the network a...
Parametric ultrasound images visualising a patient’s brain perfusion often suffer from stripe artefacts – a darker, radially oriented image region originating from inhomogeneities in the cranial bone or the dura mater. We present an algorithm for detecting these artifacts with regard to automatic evaluation of parametric images. The algorithm exploits that stripe artefacts by virtue of their or...
The nature of the Mesolithic in China has not been studied much due to few well-context sites discovered and excavated during this period. situation also restricts understanding human subsistence period China, especially arid region. present paper reports flotation results at Locality 10 Pigeon Mountain site Northwest China. Ten species plants belonging six families were identified, dominated b...
The Spread and Regional Development of Wheat Farming in the Yellow River Valley under the Han Empire
We synthesize recent archaeological discoveries on the spread of Han wheat farming, including archaeobotanical evidence, artefacts related to farming and flour processing, discovered texts such as wooden slips. cross-examine data with transmitted historical records within wider social cultural contexts Yellow River valley adjacent regions. conclude that in Middle region was slower than Lower du...
To cite: Artul S. BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013201379 DESCRIPTION High-resolution tomographic images acquired with a digital X-ray detector are often degraded by the so-called ring artefacts. Ring artefacts are the concentric rings superimposed on tomographic images. Artefacts in general can seriously degrade the quality of multidetector CT ...
In collaborative museum learning contexts, it is problematic that groups of museum visitors are not able able to touch, handle, and pass museum artefacts around during collaborative discussions. This can be due to the fragility of the artefacts themselves or due to the people discussing them being in different locations. Interacting with virtual representations of artefacts is a solution to the...
part of the Republic Moldova. The artefacts (about 150 items) were discovered in a pit, about 50 cm deep and among them were: two fibulae Röschitz-Sanislău type, seven necklaces, 12 rings, 22 tubes, 23 bracelets, 80 appliqués, coral bead, wild animal tusk pendant 21 amber beads. objects from this deposit are western origin, with known analogues deposits Poland, Hungary, Serbia, Slovakia less Ro...
The region of image compression since it is applicable to various fields of image processing. The key goal of compression is to cut back the space for storage and decrease the transmission cost and maintain the visual quality of image. This paper presents fundamental approach for analysis and evaluating the image compression techniques. This paper describes the many techniques which can be used...
