0. Abstract. PC Beta is a PC oriented tool for corpus work in this term's broadest possible sense. With PC Beta one can prepare texts for corpus work, e.g. standardize texts in different ways (very important when texts from different sources together will constitute a corpus), one can process texts, and one can analyze texts. Making ordinary concordances and similar things with PC Beta is, of c...

A firewall matches network packets to applicable policy rules based on packet dimensions (i.e., packet fields such as source and destination IP addresses). The efficiency with which firewalls match packets to rules plays a major role in determining a firewall’s overall efficiency and resistance to flooding-based denial-of-service (DoS) attacks. However, publicly available firewalls perform rule...

Background: Serial blood draws for the assessment of a trauma patient’s hemoglobin (sHgb) and hematocrit (sHct) is standard practice. In the event of multiple casualties this process can be time consuming and lead to the inefficient use of valuable resources. A device that would allow for continuous real-time, non-invasive monitoring of hemoglobin and tissue perfusion would not only improve the...

Cloud Computing is a computing model that allows ubiquitous, convenient and on-demand access to a shared pool of highly configurable resources (e.g., networks, servers, storage, applications and services). Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) attacks are serious threats to the Cloud services’ availability due to numerous new vulnerabilities introduced by the nature o...

1 Spinal Cord Service, Centro de Medicina de Reabilitação de Alcoitão, Portugal. Neste trabalho efetua-se uma reflexão sobre algumas das questões que estão a influenciar a reabilitação na atualidade. As alterações demográficas e a epidemiologia das doenças, o aumento das expectativas dos doentes, o crescimento dos custos dos cuidados de reabilitação, e também a dificuldade em estabelecer os lim...

Protein kinases control cellular responses to environmental cues by swift and accurate signal processing. Breakdowns in this high-fidelity capability are a driving force in cancer and other diseases. Thus, our limited understanding of which amino acids in the kinase domain encode substrate specificity, the so-called determinants of specificity (DoS), constitutes a major obstacle in cancer signa...

O perfil de excitação Raman do anion esquarato, C 4 O 4 -2 , foi calculado por métodos ab initio no nível de teoria Hartree-Fock utilizando a Teoria de Resposta Linear (TRL) para seis frequências de excitação: 632,5, 514,5, 488,0, 457,9, 363,8 e 337,1 nm. Um total de cinco conjuntos de funções de base (6-31G*, 6-31+G*, cc-pVDZ, aug-cc-pVDZ e bases de Sadlej) foi investigado visando comparar o d...

Nowadays, users can easily access and download network attack tools, which often provide friendly interfaces and easily operated features, from the Internet. Therefore, even a naive hacker can also launch a large scale DoS or DDoS attack to prevent a system, i.e., the victim, from providing Internet services. In this paper, we propose an agent based intrusion detection architecture, which is a ...

Denial of service (DoS) attacks figure highly among the dangers that face the Internet. Many research studies deal with DoS, proposing models and/or architectures to stop this threat. The proposed solutions vary between prevention, detection, filtering and traceback of the attack. The latter (attack traceback) constitutes an important part of the DoS defense. The most complex issue it has to fa...

Este artigo investiga o surgimento e o papel dos gestores de rede, um segmento de empresas recentemente constituído, mas que tem se revelado importante para a estruturação do canal de correspondentes bancários (CBs). A partir de um desenho de pesquisa qualitativo e de entrevistas com executivos de bancos e empresas gestoras de rede, o artigo apresenta: (i) o histórico deste segmento, e (ii) os ...
