Abstract:

Egyptian culture of the old kingdom was locally and regionally simple and efficient; belief was in the sky and humanism was regulated by Ma’at as the key concept in Egyptian mentality. IUNU was the capital of the black land KEMET where ”IUNU UNIVERSITY” is located. Physics were well studied; was already known; the right angle triangle of members 3, 4, and 5 with the 53o angle was in use. Supremacy was integrated on earth by multiple interpretations in architecture. The great pyramid of Giza was and still the best magnificent structure ever built on earth without having contemporary science’s final word been said. Massive lime stone blocks are now arranged there in a huge massive number of about two and half million pieces; their weight could reach 6.5 million tons. Conceptually there was a strong belief that symbolism connects hot spots on the Egyptian soil as it represented the known world, as well as the main stars were connected in multiple constellations on the dome of the observed sky. Pyramids of Giza plateau, Saqqara plateau, and Abusir plateau were all examples of that concept. Other pyramids of Iunu era were also related to the same concept. Structurally the Giza axis coincided on the Giza plateau. Giza plateau was a part of the Moqattam plateau during the Eocene formation. Pyramids on the worked out surface of the plateau were built with the local lime stone. Pyramids’ blocks were extracted, shaped and transported to its definite place within the precinct of the plateau. Chiseled pieces of stone - as waste from shaping blocks - were thrown out on the northern edge of the plateau. Constructional perception of what and why the Khufu pyramid took that shape shows some facts; two hundred courses composed the total existed mass where each group of courses composed a layer. Each layer started with thicker course and ended in thinner ones. Higher layers got lesser courses. So far, one should start thinking now why there were layers; why thicker and thinner courses existed. In the mean time as mortar was not in use by that time, pyramids –as in Saqqara- were formed in inclined walls, as shown in the adjacent photo. In addition, inclined walls must have formed the whole structure of Khufu pyramid.

Abstract:

AbstractThe Great Pyramid of Cholula is both the largest and oldest continuously occupied building in Mesoamerica. Initial occupation of the ceremonial precinct began in the Late Formative period, and the first building stage of the pyramid dates to the Terminal Formative. The Great Pyramid was built in four major construction stages and at least nine minor modifications. Early stages shared stylistic similarities with Teotihuacan, but toward the end of its construction history external contacts shifted to the Gulf Coast, particularly El Tajin, and probably relate to occupation by ethnic Olmeca-Xicallanca. The fourth and final stage was contemporary with extensive construction on the south side at the Patio of the Altars, and dates to the Early Postclassic period. This period ended, however, with the partial abandonment of the pyramid when ethnic Tolteca-Chichimeca constructed a ceremonial center around their “new” Pyramid of Quetzalcoatl. The Great Pyramid continued as an important shrine dedicated to mountain worship and a rain deity until the Spanish Conquest. It remains one of the most important religious sites in Mexico, where the shrine of the Virgin of the Remedies attracts pilgrims to the church atop the pyramid mound during the annual festival. This paper summarizes the archaeological and ethnohistorical information available to reinterpret the construction history and ideological content of the pyramid throughout its long existence.

Abstract:

<p>The importance of the Keops pyramid in terms of size and mass, has led to the proposal of three theories as to its modes of construction. The first theory argues that elephants and soldiers were employed for this work, which suggests considerable application of muscle power. The second states that the quarried stone blocks were transported to the pyramid construction site using elephants on a weight-bearing mechanism. The third suggests that stone blocks carried to the pyramid, were first uplifted with brute force, following which they were carried to the top, using the principle of buoyancy of water, through a system of graded pools. Theories suggested for the construction of this pyramid, can be applied to that of other pyramids. This paper analyses the construction of pyramids in terms of issues related to the quarry, stages of transport of stones from the quarry to the pyramid site and the final construction stage. Based on the theories explained in this study, the time period for the construction of the pyramid will be calculated, using expected values derived from the four different pool systems.</p><p> </p><p><strong>Özet</strong></p><p>Boyut ve kütle değerleriyle Keops Piramidi ön plana çıktığından, büyük piramitlerin inşası, bu piramit için geliştirilen üç teoriyle açıklanacaktır. Bu teorilerden birincisi, piramit inşasında kas gücünü zorlayan işlerde fil ve askerler çalıştırılabilir. İkincisi, ocaktan kesilen taş bloklar, ağırlık aktarmalı düzenekte filler kullanılarak, piramide taşınabilir. Sonuncusu, piramide taşınarak getirilen taş bloklar, kas gücünün üst sınırları zorlandığı noktaya kadar çıkarılıp, sonrasında basamaklı havuzlarda sıvının kaldırma kuvvetinden yararlanılarak üst noktaya kadar taşınıp piramit inşa edilmiş olabilir. Bu piramidin inşası için geliştirilen teoriler diğer piramitlerin inşası içinde kullanılabilir. Piramitlerin inşası; taş blokların alındığı ocak, taş blokları ocaktan piramide taşıma ve piramidin inşaat aşaması olarak üçe ayırıp, iki aşaması incelenecektir. Bu çalışmada ocak aşaması incelenmeyecektir. Burada verilecek teoriler için dört farklı havuz sistemine olası değerler verilerek piramidin inşaat süresi hesaplanacaktır.</p>

Abstract:

The topic of this paper is an analysis of the survey of Cheops pyramid (also known as the Great pyramid), the most significant of the three pyramids of the Giza complex, the archeological site on the plateau of Giza, situated on the periphery of Cairo. It is assumed that Cheops as well as Khafre and Menkaure pyramids were built around 2686 -- 2181 BC, known in the history as the Old Kingdom of Egypt. Our goal was to collect data about geodetic survey of Cheops pyramid and analyze it. Along with that, several hypotheses related to the construction method of the pyramid and possible purposes of the construction itself are described. When analyzing the survey, two numbers, also called ``two treasures of geometry'', are constantly appearing, these are the number Pi ($\pi$) and the Golden ratio or golden number Fi ($\varphi$). One of the chapters is dedicated to these numbers.

Abstract:

Inverted pyramid-texturing of silicon surface has been proven to have great application potential in silicon solar cells. In this paper, we utilized Ag-assisted chemical etching (Ag–ACE) technology combing with polyvinylpyrrolidone (PVP) to fabricate an inverted pyramid textured Si surface. We call it Ag@PVP–ACE. The effect of different experimental parameters on etching results was observed. We show that the microstructure of the Si surface exhibited two states as the concentration of NH4HF2 and PVP concentration changed: polishing and inverted pyramid texturing. Meanwhile, we found inverted pyramids easier to form at the high temperature and low H2O2 concentration of the etching system. Consequently, compared to inverted pyramid structures fabricated by nanostructure rebuilding (NSR) technology and Ag@PVP–ACE, we consider that Ag@PVP–ACE technology could become a viable strategy for fabricating inverted pyramid textured Si wafers in Si solar cells production.

Abstract:

"Earlier studies about how long it took to build the great stone pyramids focused on the cubic amounts of masonry which is not an adequate parameter for determining the achievement of pyramid builders. Rather, the appropriate parameter is lifting work measured in Joules – in brief, the product of mass multiplied by lifting height. Provided lifting of a block took on average the same time at the 4th dynasty pyramid construction sites, then there was a proportion between lifting work and building time. The upper limits of the resulting building times depend on the length of Kheops’s reign."

Abstract:

Many constructions built by ancient civilization hold many mysteries and attract the attention of historians, archaeologists and tourists from all over the world. The most famous and enigmatical among them is the Great (Khufu’s-Cheops’) Pyramid on the Giza plateau in Egypt. The assignment, construction methods and especially the inside structure of the Pyramid have been the cause of heated debate among historians and researchers since ancient times. Unfortunately, not only researchers are interested in ancient structures and excavation sites of archaeological values, but also robbers and illegal seekers of archaeological values. This led to the partial destruction of the Pyramid by the order of the Arab caliph Al-Ma’mun in the 9th century AD. From the middle of the last century, the point of view has prevailed that only non-destructive testing methods are acceptable when examining ancient structures. In the 1960s, a technology was proposed for transilluminating the pyramids of Giza by muons, which are generated by cosmic rays in the Earth’s atmosphere. This method gave promising results. Other means were also proposed, which include radar, as well as gravitational and vibration technologies. However, despite numerous attempts to use them, no significant success or discovery has been achieved. A discussion of these methods, their applications and partial successes is the subject of this article.

Abstract:

The pyramids of Egypt, and especially the Great Pyramid at Giza, have long been the subject of speculation. Notably from the mid-nineteenth century to today Western writers have proselytized numerous interpretations at odds with those of specialist scholars, and such alternative ideas have attracted wide if disparate followings. In surveys of Egypt written for a general audience from a traditional Egyptological framework these ideas are often ignored, or are lumped together as ‘pyramidiocy’. Here we emphasize the great diversity of models in pyramidologies and suggest two typological frameworks to help understand them. One applies a matrix of their ideological origins and their use of metrical applications. An alternate typology classifies pyramidologies by supposed creators and intended users of the pyramid(s). Most such theories are created by male outsiders to Egypt; they set the subject outside of the broader context of pharaonic architecture and society; they often cite scholarly sources selectively; and can incorporate mutually contradictory arguments. The internet has broadened access to alternative archaeologies, and has served to democratize fantasy.

Abstract:

ABSTRACTIn this study we compare light trapping in hydrogenated amorphous silicon (a-Si:H) solar cells deposited directly onto polycarbonate (PC) at low temperature (< 130°C). To that end, we embossed PC substrates with 400 nm and 10 μm square based pyramids to induce light trapping based on diffraction and on geometric effects. As a comparison, we deposited a-Si:H cells on flat glass substrates and on Asahi U-type TCO glass. The cells on PC generate current densities comparable (slightly higher) than cells on Asahi TCO glass, but suffer from a slightly lower Voc, resulting in cells with an initial efficiency of 6.8% and 7.4% on sub-micron pyramid and micro-pyramid structured PC substrates respectively, compared to 7.6% for cells on Asahi. This shows great potential for a-Si:H cells deposited directly onto cheap plastics.

Abstract:

The Egypt of the Pharaohs has been the subject of a huge deal of research by historians, archaeologists, and engineering specialists over the past decades. The construction of immense pyramids is largely the focus of attention insofar as it bears witness to the human genius capable of erecting monuments that have survived the millennia. The question of the logistics management involved in these majestic constructions is still little known, or at least rarely addressed. It is however undeniable that without a perfect organization of transport chains, the construction of the pyramids could not have been achieved. This article uses the example of the Great Pyramid of Giza to illustrate this point, the importance of which must be recognized by researchers specializing in management science.

ABSTRACT: The image in emblematics serves to send various messages that further enrich its visual and literary story. In this context, the pyramid plays a fundamental role, as a transmitter of multiple meanings. Its image, both archetypal and also unknown or shrouded in a certain halo of mystery, is found in emblems in great abundance. This study details the different meanings attributed to the pyramid, by means of both a visual and literary review. The visual aspect includes a great wealth of images, while the literary analysis relies not only on the motto and texts that accompany the images, but also on references to passages from classical and biblical sources, Church Fathers, and scholars from different periods. In this way, the influence of pyramids on emblematics will be attested with a profusion of symbols, allegories, and metaphors. KEYWORDSEmblem; Pyramid; Archetype.

Abstract:

The Giza pyramids, one of the world's most important archaeological sites, are threatened by urban expansion, pollution, conservation challenges, and the pressures of tourism. A critical need exists for effective site management to protect the archaeological riches of this important site. The author describes the implementation of a four-phase management plan initiated in 1988. In the first phase, an organization scheme for the site was prepared. Phase II defined a conservation and archaeological plan for the east side of the Great Pyramid and for the queens' pyramids. Phase III, which is ongoing, will define conservation of the three main pyramids, includes a tourism management plan, and will complete development of a site master plan. Phase IV will outline a program for ongoing archaeological research and conservation. The site management plan for the Giza Plateau provides a model for addressing a wide spectrum of environmental issues affecting archaeological sites.

Abstract. Digital documentation of historical sites has always required the use of expensive professional grade sensors capable of collecting large amounts of data to reconstruct cultural sites. These types of projects generally require large budgets and a large team of specialists to successfully generate a digital model. However, with smart devices having sensors capable of mapping on the go, the potential for mapping such historical sites may be more accessible. This study aims to conduct a comprehensive comparison between the iPhone 13 Pro and the Unmanned Aerial Systems (UAS) photogrammetric model of the Great Pyramid of Giza, otherwise known as the Khufu pyramid, located in Giza, Egypt. The purpose of this study is to evaluate the potential of the iPhone 13 Pro's Camera and LiDAR sensor capabilities as a valuable tool for documenting and preserving cultural heritage sites. To accomplish this, data was captured from multiple positions around the pyramid using the Pix4Dcatch app on the iPhone 13 Pro, and the data was processed using Pix4Dmatic to generate a 3D point cloud of the pyramid. This point cloud data is then compared to the reference data obtained through the UAS mapping which generated a 3D photogrammetric model. The comparison aims to identify the strengths and weaknesses of using the iPhone 13 Pro for this type of scanning and to assess the accuracy and precision of the generated data.

Abstract:

Abstract Pyramid House in Palembang is one of the works of art that is still very interesting to be researched today. The problem raised in this study aims to analyze the cultural message of the Pyramid House in Palembang. The method used is a qualitative method with a case study research design. The data collection techniques include observation, interviews, and document study. The results showed that in the manufacture of the Pyramid house, the main construction of traditional buildings used wood construction and a stilt system. The foundation used the construction of piles, the walls used boards, the roof used a leaf or shingle roof. The core parts consisted of the roof of the house, the door, the window, the stairs, and the floor of the house. In general, the typical architectural form of the Pyramid House, namely, the roof was shaped like a severed pyramid. Besides, the uniqueness of the house located in its multi-storey shape (kijing) and the walls were made of wood shaped like planks. Then related to the house name Pyramid, it contained two special meanings, namely, Five and Gold. The word five means the number five, while gold means the precious metal of great value. This is also a symbol of the function of the Pyramid house.

Abstract:

Many practical applications require flexible high-sensitivity pressure sensors. However, such sensors are difficult to achieve using conventional materials. Engineering the morphology of the electrodes and the topography of the dielectrics has been demonstrated to be effective in boosting the sensing performance of capacitive pressure sensors. In this study, a flexible capacitive pressure sensor with high sensitivity was fabricated by using three-dimensional vertical graphene (VG) as the electrode and micro-pyramidal polydimethylsiloxane (PDMS) as the dielectric layer. The engineering of the VG morphology, size, and interval of the micro-pyramids in the PDMS dielectric layer significantly boosted the sensor sensitivity. As a result, the sensors demonstrated an exceptional sensitivity of up to 6.04 kPa−1 in the pressure range of 0–1 kPa, and 0.69 kPa−1 under 1–10 kPa. Finite element analysis revealed that the micro-pyramid structure in the dielectric layer generated a significant deformation effect under pressure, thereby ameliorating the sensing properties. Finally, the sensor was used to monitor finger joint movement, knee motion, facial expression, and pressure distribution. The results indicate that the sensor exhibits great potential in various applications, including human motion detection and human-machine interaction.

Abstract:

Existing image inpainting methods based on deep learning have made great progress. These methods either generate contextually semantically consistent images or visually excellent images, ignoring that both semantic and visual effects should be appreciated. In this article, we propose a Semantic Residual Pyramid Network (SRPNet) based on a deep generative model for image inpainting at the image and feature levels. This method encodes a masked image by a residual semantic pyramid encoder and then decodes the encoded features into a inpainted image by a multi-layer decoder. At this stage, a multi-layer attention transfer network is used to gradually fill in the missing regions of the image. To generate semantically consistent and visually superior images, the multi-scale discriminators are added to the network structure. The discriminators are divided into global and local discriminators, where the global discriminator is used to identify the global consistency of the inpainted image, and the local discriminator is used to determine the consistency of the missing regions of the inpainted image. Finally, we conducted experiments on four different datasets. As a result, great performance was achieved for filling both the regular and irregular missing regions.

Abstract:

After detecting a primary triangulation through the crossing of two 18-mile (diameter) identical circles around a shared 14-mile baseline in ancient Egypt, the author hypothesizes that, in the 26th century before the Common Era, Pharaoh Khufu replaced with hope the general fear for the catlike goddess that preceded Giza’s Sphinx. Khufu changed the monstrous head of a monumental lioness on Giza’s plateau into the coarse head of the respected Horus-Pharaoh that guarded the southern lily plant and the northern papyrus. The Sphinx’s new symbolic head, or classical conservation in the finite first attention, joined flexible quantum computing in the ambiguous creativity of its body and the infinite second attention. The changed Sphinx and the Great Pyramid that followed its transfiguration point silently at the union of classical and quantum computing in the Third Attention that recreates natural systems, dreams, and social progress.

Abstract:

Pyramid-shaped InGaN/GaN micro-light-emitting diodes (μ-LEDs) were grown on a sapphire substrate using the selective area growth technique. A stable emission wavelength of a single μ-LED pyramid at 412 nm was observed under an injection current from 0.05 to 20 mA, despite the non-uniformity of the thickness and composition of the multiple quantum wells (MQWs) on the sidewall. An efficient carrier confinement and, thus, a high luminescence intensity were demonstrated in the middle of the sidewall through spatial-resolved cathodoluminescence (CL) characterization and were predicted by theoretical simulations. An ultra-high output power density of 1.37 kW/cm2 was obtained from the single μ-LED pyramid, illustrating its great potential for application in high-brightness micro-displays and in virtual reality and augmented reality (VR and AR) applications.

Abstract:

Abstract. Charles Hutton suggested in 1821 that the pyramids of Egypt be used to site an experiment to measure the deflection of the vertical by a large mass. The suggestion arose as he had estimated the attraction of a Scottish mountain as part of Nevil Maskelyne's (1774) “Schiehallion Experiment”, a demonstration of Isaac Newton's law of gravitational attraction and the earliest reasonable quantitative estimate of Earth's mean density. I present a virtual realization of an experiment at the Giza pyramids to investigate how Hutton's concept might have emerged had it been undertaken as he suggested. The attraction of the Great Pyramid would have led to inward north–south deflections of the vertical totalling 1.8 arcsec (0.0005∘), and east–west deflections totalling 2.0 arcsec (0.0006∘), which although small, would have been within the contemporaneous detectable range, and potentially given, as Hutton wished, a more accurate Earth density measurement than he reported from the Schiehallion experiment.

Abstract:

Terrain segmentation is of great significance to robot navigation, cognition, and map building. However, the existing vision-based methods are challenging to meet the high-accuracy and real-time performance. A terrain segmentation method with a novel lightweight pyramid scene parsing mobile network is proposed for terrain segmentation in robot navigation. It combines the feature extraction structure of MobileNet and the encoding path of pyramid scene parsing network. The depthwise separable convolution, the spatial pyramid pooling, and the feature fusion are employed to reduce the onboard computing time of pyramid scene parsing mobile network. A unique data set called Hangzhou Dianzi University Terrain Dataset is constructed for terrain segmentation, which contains more than 4000 images from 10 different scenes. The data set was collected from a robot’s perspective to make it more suitable for robotic applications. Experimental results show that the proposed method has high-accuracy and real-time performance on the onboard computer. Moreover, its real-time performance is better than most state-of-the-art methods for terrain segmentation.
