Yayın A cost-efficient bit-serial architecture for sub-pixel motion estimation of H.264/AVC(IEEE Computer Soc, 2008) Fatemi, Mohammad Reza Hosseiny; Ateş, Hasan Fehmi; Salleh, Rosli BinThis paper presents a new VLSI architecture for sub-pixel motion estimation in H.264/AVC encoder. It is based on an interpolation free algorithm that causes a high level reduction on memory requirement, hardware resources and computational complexity. A high performance, bit-serial pipeline architecture is proposed for quarter pixel accurate motion estimation which supports real-time H.264 encoding. Due to the bit-serial, modular and reusable architecture, it provides significant improvement in area cost (at least 390) and increases the macroblock processing speed almost 6 times when compared with the previous designs. The proposed architecture is suitable for portable multimedia devices where the memory and power consumption are limited.Yayın A bit-serial sum of absolute difference accelerator for variable block size motion estimation of H.264(IEEE, 2009) Fatemi, Mohammad Reza Hosseiny; Ateş, Hasan Fehmi; Salleh, Rosli BinBit-serial architectures offer a number of attractive features over their bit-parallel counterparts such as smaller area cost, lower density interconnection, a reduced number of pins, higher clock frequency, simpler routing and etc. These attractive features make them suitable for using in VLSI design and reduce overall production cost. In this paper, we propose the first least significant bit (LSB) bit-serial sum of absolute difference (SAD) hardware accelerator for integer variable block size motion estimation (VBSME) of H.264. This hardware accelerator is based on a previous state-of-art bit-parallel architecture namely propagate partial SAD. In order to reduce area cost and improve throughput, pixel truncation technique is adopted. Due to the bit-serial pipeline architecture and using small processing elements, our architecture works at much higher clock frequency (at least 4 times) and reduces area cost about 32% compared with its bit-parallel counterpart. The proposed hardware accelerator can be used in different disciplines from low bit rate to high bit rate by making a tradeoff between the degree of parallelism or using fast algorithm or a combination of both.Yayın High-rise buildings in cultural code of Istanbul: Büyükdere avenue example(ICNTAD Secretariat, 2020-10) Ölgen, Burcu; Özker, SerpilThe definition of the industrial city, which emerged with the industrial revolution, caused the urban perception to change and transform as the production units started to move to the city periphery in the 20th century. Population growth, rapid urbanization and changing social needs have made high-rise buildings inevitable for big cities. In this study, it was aimed to examine the change and transformation of the Istanbul Büyükdere region, which hosted the industrial structures of Istanbul for a period, as well as the spatial and urban context of mixed-function high-rise buildings, which are one of the most prominent examples that determine the current building stock of the region and to examine their effects on urban development. In this direction, analysis of the transformation of the city, space, and the users have been made through the examples of buildings on the Levent-Maslak axle. Büyükdere Avenue is a region where high-rise building stock is located on the central axle, and where the high-value buildings are located in the city. As a result, it has been concluded that in the Levent-Maslak axle, there has been a rise in sheltered office-housing-activity areas for the high-income group due to the earning concerns of large companies and this increased the interest to the region.Yayın A woman pioneer in archeology and conservation in Turkey: Halet Çambel(Politecnico di Torino, 2018-06) Bolca, Pelin; Karadağ, DeryaIt is known that traditional Ottoman culture has always discriminated women in everyday life as well as in the workplace. However, with the foundation of the Republic of Turkey in 1923, modernisation studies have been started throughout the country. This “modern movement” has led to change the perception of gender discrimination. One of the important Republican reforms was equality of women and men. Thus, the achievements of women have been getting visible since then. Although in the last period of the Ottoman Empire, the prevalence of archaeology was understood, archaeological research had a limited place in the architectural context. However, after the Republican reforms, archaeology world saw the first woman figure as well as one of the most important archaeologists, Halet Çambel. In 1938, she received her undergraduate degree in archaeology from the Sorbonne University in Paris. Then she came back to Turkey and started working at Istanbul University. Her career has gained a remarkable advance with the excavation of Karatepe-Arslantaş Mound at the southern side of Turkey. In the present days, these excavations, which continued under Çambel’s leadership, are known as the site where Hittite hieroglyphs became understandable. She also was leading the conservation and restoration studies of the archaeological finds. Therefore, she established an open-air museum which is the first for Turkey. Çambel’s achievements were not limited to archaeology. She was also teaching at Istanbul University and she contributed to the creation of a modern method of archaeological research in Turkey. This paper examines the achievements of Halet Çambel on her particular legacy. The focus of the paper is to investigate the influences of Modern Movement to Halet Çambel’s career. By doing such analysis, women achievements in the architecture and archaeology after the foundation of the Republic of Turkey are discussed.
