Γύψινες ανάγλυφες διακοσμήσεις της μεσοβυζαντινής εποχής στο καθολικό της μονής Ιβήρων

In addition to the marble sculptures, the katholikon of Iviron Monasteryincludes some most remarkable plaster relief ornamentation from the middleByzantine period. One such plaster relief, framing the arch-shaped opening ofthe funerary arcosolium at the north end of the inner narthex, has beenexamined in the context of the study of the monastery founders’ tombs[Th. N. Pazaras, «Founders’ tombs in the katholikon of Iviron Monastery»,Byzantina 26 (2006) 125-151 (to be published shortly)]. The main subject of this study is another such piece of plasterornamentation, in the form of a triple arch, which can be found above thelintel of the Imperial Door, that is the central door leading from the narthexinto the naos. This plaster archwork is composed of a central elevated arch,supported by two colonettes and framed on both sides by two lower quartercircle arches. The roots of such a conception of a triple, symmetrical archwork are perhaps to be sought in Middle Byzantine Constantinopolitan architecture, even though similar ornamental compositions can also be found inivory work and in illuminated manuscripts from the same period.All arches are adorned with various scrolls and are framed on the outsideby tightly braided guilloches, with either a fine dentil course or a series ofstylized bead-and-reel along the inner edge. The colonettes of the middle archare likewise covered from base to capital with relief ornamentation. All those themes are in very wide use in Middle Byzantine decorative art,whether in monumental painting and illuminated manuscripts or in miniatureart and above all in sculpture. This leads us to date the plaster archwork tothe 10th-11th century. Using what is known about the foundation of theMonastery and the building history of the katholikon, in conjunction with thetestimony of archival sources, one can even attempt a more precise dating,from the end 10th to mid-11th century. This estimate can be narrowed downeven further, to some time between 1029 and 1066, for the archwork underconsideration appears to be closely related to the plaster relief archwork ofthe above mentioned northern grave of the inner narthex of the samekatholikon, which was built between those same years

Training activities for industrial workers

The I.L.O.'s work in Africa in the field of training for industrial workers including middle grade personnel, goes back many years. It has recently developed very considerably and very rapidly, due largely to· the development of the various forms of technical aid programme and the achievement of independent status in the last few years by virtually all African states

Wordsworth's death and the figure of the poet in 1850

This article will consider the extent and nature of the celebrity of the Poet Laureate William Wordsworth, who died in 1850. Ostensibly the most famous English poet alive in that year, on his death on 23 April 1850, Wordsworth had been Poet Laureate for just over seven years and had been actively producing verse since 1793. Shortly after his death, his longest poem, now considered a masterpiece of autobiographical epic, The Prelude, was published; one could easily assume that the death of such a major poet coupled with the publication of one of his most significant works would dominate the literary world in that year; yet notices of his death, while widespread, were fleeting in focus, and The Prelude met with a lukewarm reception. This challenges the concept of even a Poet Laureate as a literary celebrity. Nonetheless, as I will show, his name endured as a byword for ‘poet’ in periodicals of the time, and the Wordsworthian pastoral lyric remained an enduring form in periodicals of the year of his death; meaning that Wordsworth as a figure of ‘true poet’ endured even as his personal celebrity had waned

Microwave breast imaging using compressed sensing approach of iteratively corrected delay multiply and sum beamforming

Microwave imaging (MI) is a consistent health monitoring technique that can play a vital role in diagnosing anomalies in the breast. The reliability of biomedical imaging diagnosis is substantially dependent on the imaging algorithm. Widely used delay and sum (DAS)-based diagnosis algorithms suffer from some significant drawbacks. The delay multiply and sum (DMAS) is an improved method and has benefits over DAS in terms of greater contrast and better resolution. However, the main drawback of DMAS is its excessive computational complexity. This paper presents a compressed sensing (CS) approach of iteratively corrected DMAS (CS-ICDMAS) beamforming that reduces the channel calculation and computation time while maintaining image quality. The array setup for acquiring data comprised 16 Vivaldi antennas with a bandwidth of 2.70-11.20 GHz. The power of all the channels was calculated and low power channels were eliminated based on the compression factor. The algorithm involves data-independent techniques that eliminate multiple reflections. This can generate results similar to the uncompressed variants in a significantly lower time which is essential for real-time applications. This paper also investigates the experimental data that prove the enhanced performance of the algorithm. 2021 by the authors.

Accuracy evaluation of the semi-automatic 3D modeling for historical building information models

It is stated that 3D recording and modelling of heritage buildings entails accurate building models (as-built). However, this paper presents an analysis of the 3D modelling accuracy for the creation of historical building information models (HBIM), considering the complexity and the deformations of historical buildings, using point cloud data and BIM tools. The 3D modelling processes analysed are based on a three-stage semi-automatic approach leading to the generation of HBIM, including manual and automatic processes. The three stages consist of: (a) optical and terrestrial laser scanning; (b) meshing processes; and finally (c) 3D solid modelling to be assembled into HBIM. Next, this approach analysed the mesh deformations generated automatically in comparison to the initial point cloud data. The deformations and the accuracy evaluation have been undertaken using different commercial software. Finally, our modelling approach shows that it can improve the accuracy of the 3D models achieved using existing BIM technologies
