Profiling And Identification Of Web Applications In Computer Network, Hussein Oudah Jan 2020

Profiling And Identification Of Web Applications In Computer Network, Hussein Oudah

School of Engineering, Computing and Mathematics Theses

Characterising network traffic is a critical step for detecting network intrusion or misuse. The traditional way to identify the application associated with a set of traffic flows uses port number and DPI (Deep Packet Inspection), but it is affected by the use of dynamic ports and encryption. The research community proposed models for traffic classification that determined the most important requirements and recommendations for a successful approach. The suggested alternatives could be categorised into four techniques: port-based, packet payload based, host behavioural, and statistical-based. The traditional way to identifying traffic flows typically focuses on using IANA assigned port numbers and …

Activity-Based User Authentication Using Smartwatches, Neamah Hasan Al-Naffakh Jan 2020

Activity-Based User Authentication Using Smartwatches, Neamah Hasan Al-Naffakh

School of Engineering, Computing and Mathematics Theses

Smartwatches, which contain an accelerometer and gyroscope, have recently been used to implement gait and gesture- based biometrics; however, the prior studies have long-established drawbacks. For example, data for both training and evaluation was captured from single sessions (which is not realistic and can lead to overly optimistic performance results), and in cases when the multi-day scenario was considered, the evaluation was often either done improperly or the results are very poor (i.e., greater than 20% of EER). Moreover, limited activities were considered (i.e., gait or gestures), and data captured within a controlled environment which tends to be far less …

Honeypot For Wireless Sensor Networks, Jürgen Markert Jan 2020

Honeypot For Wireless Sensor Networks, Jürgen Markert

School of Engineering, Computing and Mathematics Theses

People have understood that computer systems need safeguarding and require knowledge of security principles for their protection. While this has led to solutions for system components such as malware-protection, firewalls and intrusion detection systems, the ubiquitous usage of tiny microcomputers appeared at the same time. A new interconnectivity is on the rise in our lives. Things become “smart” and increasingly build new networks of devices. In this context the wireless sensor networks here interact with users and also, vice versa as well; unprivileged users able to interact with the wireless sensor network may harm the privileged user as a result. …

Proactive Biometric-Enabled Forensic Imprinting System, A Alruban

School of Engineering, Computing and Mathematics Theses

Insider threats are a significant security issue. The last decade has witnessed countless instances of data loss and exposure in which leaked data have become publicly available and easily accessible. Losing or disclosing sensitive data or confidential information may cause substantial financial and reputational damage to a company. Therefore, preventing or responding to such incidents has become a challenging task. Whilst more recent research has focused explicitly on the problem of insider misuse, it has tended to concentrate on the information itself—either through its protection or approaches to detecting leakage. Although digital forensics has become a de facto standard in …

Zechipc: Time Series Interpolation Method Based On Lebesgue Sampling, Luis Miralles-Pechuán, Muhammad Atif Qureshi, Matthieu Bellucci, Brian Mac Namee Jan 2020

Zechipc: Time Series Interpolation Method Based On Lebesgue Sampling, Luis Miralles-Pechuán, Muhammad Atif Qureshi, Matthieu Bellucci, Brian Mac Namee

Books/Book Chapters

In this paper, we present an interpolation method based on Lebesgue sampling that could help to develop systems based time series more efficiently. Our methods can transmit times series, frequently used in health monitoring, with the same level of accuracy but using much fewer data. Our method is based in Lebesgue sampling, which collects information depending on the values of the signal (e.g. the signal output is sampled when it crosses specific limits). Lebesgue sampling contains additional information about the shape of the signal in-between two sampled points. Using this information would allow generating an interpolated signal closer to the …

Covid -19 And The Need For Robust Risk Control Strategies: Can Ich-Q9 Help?, Umit Kartoglu, Kevin O'Donnell, James Vesper Jan 2020

Covid -19 And The Need For Robust Risk Control Strategies: Can Ich-Q9 Help?, Umit Kartoglu, Kevin O'Donnell, James Vesper

Level 3

The COVID-19 pandemic requires robust risk control strategies; these should be multi-layered, science-based and subjected to effectiveness checks and formal reviews, to identify any unintended consequences. They should be supported by communications informed by an understanding of biases and risk perception. While developing such strategies for COVID-19 is difficult, given the scale of the problem and the diversity of stakeholders, the approach to Quality Risk Management (QRM) used by the pharmaceutical industry provides governments and public health officials with a ready-made framework to arrive at such control strategies. This approach is set out in the ICH Guideline on Quality Risk …

Understanding The Concept Of Formality In Quality Risk Management, Kevin O'Donnell, Deirdre Tobin, Stephanie Butler, Ghada Haddad, Donal Kelleher Jan 2020

Understanding The Concept Of Formality In Quality Risk Management, Kevin O'Donnell, Deirdre Tobin, Stephanie Butler, Ghada Haddad, Donal Kelleher

Level 3

Formality in Quality Risk Management (QRM) is an interesting concept. What makes a QRM activity ‘formal’ and what makes one ‘informal’? A simplistic viewpoint might be that formal is when a QRM tool is used to manage risks, and informal is when no such tool is used. But is it that simple? And are there different degrees of formality in QRM - is it a spectrum, or is it a binary concept? These questions are explored in this paper. Since the introduction of ICH Q9 in 2005, there have been discussions in the pharmaceutical industry and between regulators regarding the …

Quantification Of Low-Content Encapsulated Active Cosmetic Ingredients In Complex Semi-Solid Formulations By Means Of Attenuated Total Reflectance-Infrared Spectroscopy, Franck Bonnier, Lynda Miloudi, Sandra Henry, Dominique Bertrand, Clovis Tauber, Xavier Perse, Florent Yvergnaux, Hugh Byrne, Igor Chourpa, Emilie Munnier

Articles

Attenuated total reflectance-infrared (ATR-IR) spectroscopy is a robust tool for molecular characterisation of matter. Applied to semi-solid formulations, it enables rapid and reliable data collection without pre-analytical requirements. Based on nano-encapsulated Omegalight®, a skin-lightening active cosmetic ingredient (ACI), incorporated in a hydrogel, it is first demonstrated that, despite the high water content and the chemical complexity of the samples (i.e. number of ingredients), the spectral features of the ACI can be detected and monitored. Secondly, with a total of 105 samples divided into a training set (n = 60) and an unknown set (n = 45) covering a …

Exploiting Fourier Transform Infrared And Raman Microspectroscopies On Cancer Stem Cells From Oral Squamous Cells Carcinoma: New Evidence Of Acquired Csplatin Chemoresistance, Valentina Notarstefano, Simona Sabbatini, Chiaro Pro, Alessia Belloni, Giulia Orilisi, Corrado Rubini, Hugh Byrne, Lisa Vaccari, Elisabetta Giorgini

Articles

Oral Squamous Cells Carcinoma (OSCC) is characterised by the risk of recurrence and the onset of a refractoriness response to chemotherapy drugs. These phenomena have been recently related to a subpopulation of Cancer Stem Cells (CSCs), which have either an innate or acquired drug resistance, triggered by chemotherapy treatments. In this light, to precisely target chemotherapy regimens, it is essential to improve knowledge on CSCs, with a particular focus on their molecular features. In this work, a subpopulation of CSCs, isolated by tumour sphere formation from primary OSCC cells, were treated with cisplatin for 16, 24 and 48 hours and …

K-Means And Hierarchical Cluster Analysis As Segmentation Algorithms Of Ftir Hyperspectral Images Collected From Cutaneous Tissue, Cassio Lima, Luciana Correa, Hugh Byrne, Denise Zezell

Conference papers

Fourier Transform Infrared (FTIR) spectroscopy is a rapid and label-free analytical technique whose potential as a diagnostic tool has been well demonstrated. The combination of spectroscopy and microscopy technologies enable wide-field scanning of a sample, providing a hyperspectral image with tens of thousands of spectra in a few minutes. In order to increase the information content of FTIR images, different clustering algorithms have been proposed as segmentation methods. However, systematic comparative tests of these techniques are still missing. Thus, the present paper aims to compare the ability of K-means Cluster Analysis (KMCA) and Hierarchical Cluster Analysis (HCA) as clustering algorithms …

Consciousness As A Factor In Evolution, Kenneth A. Augustyn Jan 2020

Consciousness As A Factor In Evolution, Kenneth A. Augustyn

Michigan Tech Publications, Part 1

What I call the mind began as a non-conscious robotic biochemical process control system in the very earliest forms of life. As life evolved, problems in control became more difficult and exceeded the computational capabilities of the organisms. Nature discovered a means of transcending computable physical processes resulting in non-computational subjective mental capabilities that, while still not conscious, had a degree of genuine autonomy from the physical world. These autonomous subjective wants and goals now affected the course of (but not the mechanism of) evolution. The integrated amalgam of robotic and transrobotic unconscious capabilities eventually gave rise to consciousness, which …

Vehicle Exhaust Remote Sensing Device Method To Screen Vehicles For Evaporative Running Loss Emissions, Gary A. Bishop, Timothy H. Defries, James A. Sidebottom, James M. Kemper

Fuel Efficiency Automobile Test Publications

Vehicle hydrocarbon (HC) emissions can be emitted from either tailpipe or non-tailpipe locations and understanding their fleet apportionment is important for successful air pollution policy. Vehicles initially misidentified as having elevated tailpipe HC emissions first indicated that roadside exhaust sensors could detect the presence of evaporative HC emissions as increased noise in the HC/carbon dioxide (CO2) correlation measurement. The 90th percentile of the largest residual of the HC/CO2 correlation is defined as a running loss index (RLI) for each measurement. An RLI that is three standard deviations or greater above the instruments noise indicates possible evaporative …

Pilot Scale Pyrolysis Of Activated Sludge Waste From Milk Processing Factory, Marzena Kwapinska, Alen Horvat, Yupeng Liu, James Leahy

Articles

The majority of the sludge from the treatment of wastewater in milk processing plants is land spread. The drawbacks of land spreading include local oversupply due to high transport costs, which results in sludge being spread on lands in the vicinity of the dairy factories. Local oversupply can lead to accumulation of certain substances in soil through annual application over many years. Therefore, in the long term, there is a need for alternative methods to recover energy and nutrients from increasing volumes of sludge generated from dairy processing. Pyrolysis ofers a potential alternative to land spreading, which can reduce health …
