Analysis of advanced programming architectures for next-generation Flash memories
No full textIn this paper, we study the error performance of programming architectures for Flash memories. Specifically, we propose an advanced programming architecture and evaluate its performance via computer simulations. We show that the proposed method can improve the error performance under severe interfering effects, which is the case for the next-generation Flash memories with very small cells employing multiple levels
A temporal analysis of vessel type traffic in Istanbul Strait anchorages
No full textA large number of vessels berth in the anchorage
areas of the Istanbul Strait on a daily basis for various reasons
including bunkering and supply, port operation, lay-up, waiting
for Strait passage, and bad weather conditions. These anchorage
areas are zoned based on vessel type by maritime authorities
where precise considerations need to be made according to the
variation in vessel type. In this study, we first present a temporal
analysis of vessel type traffic between 2006 and 2013 using a new
historical dataset. Next, we forecast vessel type traffic for the
next three years using the statistical ARIMA model. Our results
suggest an overall decrease of berthing vessels, yet a pronounced
increase in LPG barges. This finding is rather significant as this
type of vessel is more prone to accidents and any such accident
would pose a great danger to the Strait, which in turn, implies an
urgent need for revising current anchorage zoning practices

Automating unambiguous NOE data usage in NVR for NMR protein structure-based assignments
No full textNuclear Magnetic Resonance (NMR) Spectroscopy is an important technique that allows determining protein structure in solution. An important problem in protein structure determination using NMR spectroscopy is the mapping of peaks to corresponding amino acids, also known as the assignment problem. Structure-Based Assignment (SBA) is an approach to solve this problem using a template structure that is homologous to the target. Our previously developed approach Nuclear Vector Replacement-Binary Integer Programming (NVR-BIP) computed the optimal solution for small proteins, but was unable to solve the assignments of large proteins. NVR-Ant Colony Optimization (ACO) extended the applicability of the NVR approach for such proteins. One of the input data utilized in these approaches is the Nuclear Overhauser Effect (NOE) data. NOE is an interaction observed between two protons if the protons are located close in space. These protons could be amide protons, protons attached to the alpha-carbon atom in the backbone of the protein, or side chain protons. NVR only uses backbone protons. In this paper, we reformulate the NVR-BIP model to distinguish the type of proton in NOE data and use the corresponding proton coordinates in the extended formulation. In addition, the threshold value over interproton distances is set in a standard manner for all proteins by extracting the NOE upper bound distance information from the data. We also convert NOE intensities into distance thresholds. Our new approach thus handles the NOE data correctly and without manually determined parameters. We accordingly adapt NVR-ACO solution methodology to these changes. Computational results show that our approaches obtain optimal solutions for small proteins. For the large proteins our ant colony optimization-based approach obtains promising results
Rate/distortion optimization in multiple description video coding
No full textMultiple Description Coding (MDC) is a technique where multiple streams from a video source are generated, each individually decodable and mutually refinable. MDC is a promising solution to overcome packet loss in video transmission over noisy channels, particularly for real-time applications in which retransmission of lost information is not practical. The error resiliency feature of MDC is achieved at the cost of redundancy, and the required amount of redundancy for each frame depends on the packet loss ratio and also the importance of the frame in the sequence. Due to the error propagation in video transmission over lossy channels, reference frames of a Group of Pictures (GOP) are more important for video reconstruction and, hence, need more redundancy to increase the chance of being received correctly. Therefore a channel adaptive optimization for frame-wise redundancy allocation is needed. In this paper, based on the difference of the side and central decoder outputs, the receiver side distortion is formulated and then used for optimization of a MDC scheme. The performance of the optimizer is verified by experimental results measured from JM 16.0, H.264/AVC reference software

Between Turkishness and Kurdishness : social cohesion of Central Anatolian Kurds
No full textTezin basılısı İstanbul Şehir Üniversitesi Kütüphanesi'ndedir.This study tries to display patterns in the political, social and cultural lives of Central Anatolian Kurds and how these patterns and Kurdish identity are impacted by surrounding influences of Turkishness. In accordance with this purpose and to understand the roots of the existing Kurdish population in the region, the first phase of this study has examined the historical background of Kurdish settlement in Central Anatolia through the Imperial and Republican periods. In the second phase, semi- structured interviews with Central Anatolian Kurds and non-structured interviews with researchers and members of foundations were conducted to demonstrate the possibilities and limitations of social interactions with other groups as well as within the Central Anatolian Kurdish community, which give clues about their cohesion/exclusion level. Field work held as a part of this study is framed by Paul Bernard’s classification of measuring cohesion in social, cultural, and political aspects under three dimensions named as 1) Recognition/Rejection: Dealing with experiences, feelings, expectations, preferences, and concerns about social relations; 2) Belonging/Isolation: Touching upon shared values shaped by elements of ethnic contours; and 3) Legitimacy/Illegitimacy: Interest in relations with political and institutional foundations. The main argument of this study is that ethnic contours of Central Anatolian Kurds have been shaped by elements of Turkishness as well as Kurdishness, placing this group in-between two ethnicities.ABSTRACT ................................................................................................................ iv

Reconfigurable and transformational product design concepts and applications : a case study of innovative furniture
No full textTezin basılısı İstanbul Şehir Üniversitesi Kütüphanesi'ndedir.Multifarious design methods have been developed in engineering and art disciplines in the
search of better quality, efficiency, cost-effectiveness, functionality, and novelty. Trans-
formational and reconfigurable devices in different fields have become trendier after the
20th century. Customers expect both enhanced performances and reduced complexity
level on their products. Compared to static state products with single function amongst
furniture product category, the product items with transformational functionality and
reconfigurablility possess higher ability for coping different customer needs and expecta-
tions. For this case, research and development on innovative, novel product with specific
design methodology is essential. In this paper, by reviewing and synthesizing previous
research on transformational design and reconfigurable product systems, we carried out
the integration of different structures and products, which are from various single state
products. These processes are all under the transformational, flexible, reconfigurable
design guidelines to obtain the overall function structure of the ideal integrated product.Declaration of Authorship ii

An improved formalism for assigning proteins using nuclear vector replacement framework
No full textTezin basılısı İstanbul Şehir Üniversitesi Kütüphanesi'ndedir.Proteins are macromolecules in living systems used in crucial functions in all biological processes. In order to understand the function of a protein it is necessary to determine the structure of it. There are various techniques to obtain structural information and Nuclear Magnetic Resonance (NMR) Spectroscopy is one of the most important ones. In this technique, an essential step is the backbone resonance assignment and Structure Based Assignment (SBA) is a method solving this problem with the help of a template structure. NVR is an NMR protein SBA program, that takes as input 15N and HN chemical shifts and unambiguous NOEs, as well as RDCs, HD-exchange and TOCSY data. To run NVR, there is a sequence of steps in obtaining the datales from NMR data and the template structure. In this study, the process of preparing these datales is simpliedandautomatized, whichisanimportantpracticalstepinrunningNVRonnovel proteins. A method to distinguish NH2 peaks from HSQC peaks is generated. Finally, rather than computing a single assignment, an ensemble of assignments is computed. Using this ensemble of assignment results, degree of reliability for individual peak-amino acid assignments is obtained and assignment accuracy is improved. The results show that these improvements bring NVR closer to a tool to be useful and practical tool, able to handle the input data automatically and analyze the reliability of assignments.Declaration of Authorship ii
