In recent years, many systems that use RFIDs for building low-cost wireless systems have been proposed. However, due to their limited computational capabilitynand simple structure, important issues and challenges remain unsolved in RFID-based systems. There are two key challenge…
As coleções científicas, reunindo uma enorme quantidade e diversidade de objetos e os dados que lhes estão associados, constituem um valioso património histórico, científico e cultural. Estas coleções estão, geralmente, sob a responsabilidade dos museus e dos seus respetivos cur…
“A cyborg is a cybernetic organism, a hybrid of machine and organism, a creature of social reality as well as a creature of fiction” (Haraway, 1985: 1). In the age of the Anthropocene we find ourselves on a cyborg planet, an entity with both biological with physical and technolo…
Reconstructing evolutionary trees, also known as phylogenies, from molecular sequence data is a fundamental problem in computational biology. Classically, evolutionary trees have been estimated over a set of species, where leaves correspond to extant species and internal nodes c…
A metodologia Lean tem como objetivo a melhoria contínua de processos de trabalho, propósitos e pessoas. Promove a versatilidade, flexibilidade, qualidade de produto ou serviço e redução do desperdício. São ainda encorajadas a responsabilidade e liderança partilhadas. Os valores…
Existem inúmeras minas desativadas que apresentam um elevado valor patrimonial e histórico. Contudo a maioria destas minas acaba por não ser documentadas com o devido cuidado, existindo o risco de deterioração do património com o passar do tempo, pelo que se torna necessária a e…
Bu araştırma; dünyadaki bütün toplumların hayatlarını farklı farklı etkileyen dindarlık olgusunu, iki toplumdan misal vererek alınan örneklem üzerindeki etkilerini ve durumlarını incelemektedir. Bu araştırmanın ana gayesi, İstanbul Üniversitesi'nin çeşitli fakültelerinden 657 öğ…
Image Forensics has become an important area of research due to the exponential increase in availability and free exchange of media. The accessibility to good quality sensors and image hosting websites is now at the disposal of more users than ever. The increase in sharing of im…
MRI is a medical machine with a large magnet and radio waves to scan organs and body structures, especially in the head scans. During the scanning process, head motion is a major source of error for brain MRI. There is no direct method to assess head motion during MRI scans. To …
In this research study, MATLAB PDE Toolbox is investigated for modeling a two-dimensional (2-D) and three-dimensional (3-D) pressurized water reactor (PWR) core. MATLAB PDE Toolbox is a partial differential equation (PDE) solver for finite element method (FEM) analysis. The PDE …
Each day, a tremendous number of opinions are posted about different issues and different subjects from massive active users on social media. While people increasingly use social media applications such as Twitter to express their feelings and opinions about many things such as …
With the current technological advancements, an extraordinary amount of data is available over the Internet. 59% of the world population, which accounts to 4.57 billion people have access to the Internet and retrieve or generate a variety of data and information through it. Also…
The unique features of blockchain such as transparency, provenance, and authenticity are used by many large-scale data management systems to deploy a wide range of distributed applications including supply chain management, healthcare, and crowdsourcing in a permissioned setting…
In the past decade, cloud computing has disrupted the computing landscape by providing economical compute and storage resources as services to end-users. Many web-based internet applications, such as Airbnb, Pinterest, and Expedia, are now hosted on public clouds because of the …
One of the expected benefits of a modular design is flexibility. By the word "flexibility" we mean possibility of drastic changes to a module without changing or without knowing other modules. Based on the evolutionary data available on version control systems, it should be poss…
The prevalence of big data analytics in almost every large-scale software system has generated a substantial push to build data-intensive scalable computing (DISC) frameworks such as Google MapReduce and Apache Spark that can fully harness the power of existing data centers. How…
Cloud computing has provided many services to potential consumers, one of these services being the provision of network functions using virtualization. Network Function Virtualization is a new technology that aims to improve the way we consume network services. Legacy networking…
With the ever-growing need for connectivity in this era of smart and autonomous systems, we are observing an extensive use of network services. The increasing use of cyber technology, however, leads to the proliferation of security threats. Therefore, it is essential to design a…
