description: The selection of the best classification algorithm for a given dataset is a very widespread problem, occuring each time one has to choose a classifier to solve a real-world problem. It is also a complex task with many important methodological decisions to make. Among those, one of the most crucial is the choice of an appropriate measure in order to properly assess the classification performance and rank the algorithms. In this article, we focus on this specific task. We present the most popular measures and compare their behavior through discrimination plots. We then discuss their properties from a more theoretical perspective. It turns out several of them are equivalent for classifiers comparison purposes. Futhermore. they can also lead to interpretation problems. Among the numerous measures proposed over the years, it appears that the classical overall success rate and marginal rates are the more suitable for classifier comparison task.
Advances in medical image compression : novel schemes for highly efficient storage, transmission and on demand scalable access for 3D and 4D medical imaging data
Creators: name: Sanchez Silva, Victor F
Publisher: name: University of British Columbia

description: Three dimensional (3D) and four dimensional (4D) medical images are increasingly being used in many clinical and research applications. Due to their huge file size, 3D and 4D medical images pose heavy demands on storage and archiving resources. Lossless compression methods usually facilitate the access and reduce the storage burden of such data, while avoiding any loss of valuable clinical data. In this thesis, we propose novel methods for highly efficient storage and scalable access of 3D and 4D medical imaging data that outperform the state-of the-art. Specifically, we propose (1) a symmetry-based technique for scalable lossless compression of 3D medical images; (2) a 3D scalable medical image compression method with optimized volume of interest (VOI) coding; (3) a motion-compensation-based technique for lossless compression of 4D medical images; and (4) a lossless functional magnetic resonance imaging (fMRI) compression method based on motion compensation and customized entropy coding. The proposed symmetry-based technique for scalable lossless compression of 3D medical images employs wavelet transform technology and a prediction method to reduce the energy of the wavelet sub-bands based on a set of axes of symmetry. We achieve VOI coding by employing an optimization technique that maximizes reconstruction quality of a VOI at any bit-rate, while incorporating partial background information and allowing for gradual increase in peripheral quality around the VOI. The proposed lossless compression method for 4D medical imaging data employs motion compensation and estimation to exploit the spatial and temporal correlations of 4D medical images. Similarly, the proposed fMRI lossless compression method employs a motion compensation process that uses a 4D search, bi-directional prediction and variable-size block matching for motion estimation; and a new context-based adaptive binary arithmetic coder to compress the residual and motion vector data generated by the motion compensation process. We demonstrate that the proposed methods achieve a superior compression performance compared to the state-of-the-art, including JPEG2000 and 3D-JPEG2000.

description: We propose a method of quantization based on Hamilton-Jacobi theory in the presence of a random constraint due to the fluctuations of a set of hidden random variables. Given a Lagrangian, it reproduces the results of canonical quantization yet with a unique ordering of operators if the Lagrange multiplier that arises in the dynamical system with constraint can only take binary values $\pm\hbar/2$ with equal probability.

description: Digital gaming plays out within different environments—from arcades to virtual worlds to the family living room. Each of these gaming environments offer different constraints and affordances for gaming. As gaming environments change, so do the kinds of games people play, the populations of gamers that gather, and the social interactions surrounding gaming. In this paper, we explore the domestic gaming environment. We examine data that suggests that the domestic environment is now the most common environment for gaming. We characterize existing domestic gaming environments and contrast these gaming environments with participants visions of their ideal gaming environment; these findings suggest that the participants in this study wanted gaming environments that would embody a technologically mediated hospitality.
Hubble Space Telescope Pixel Analysis of the Interacting Face-on Spiral Galaxy NGC 5194 (M51A)

description: A pixel analysis is carried out on the interacting face-on spiral galaxy NGC 5194 (M51A), using the HST/ACS images in the F435W, F555W and F814W (BVI) bands. After 4x4 binning of the HST/ACS images to secure a sufficient signal-to-noise ratio for each pixel, we derive several quantities describing the pixel color-magnitude diagram (pCMD) of NGC 5194: blue/red color cut, red pixel sequence parameters, blue pixel sequence parameters and blue-to-red pixel ratio. The red sequence pixels are mostly older than 1 Gyr, while the blue sequence pixels are mostly younger than 1 Gyr, in their luminosity-weighted mean stellar ages. The color variation in the red pixel sequence from V = 20 mag arcsec^(-2) to V = 17 mag arcsec^(-2) corresponds to a metallicity variation of Δ[Fe/H] ~ 2 or an optical depth variation of Δτ_V ~ 4 by dust, but the actual sequence is thought to originate from the combination of those two effects. At V < 20 mag arcsec^(-2), the color variation in the blue pixel sequence corresponds to an age variation from 5 Myr to 300 Myr under the assumption of solar metallicity and τ_V = 1. To investigate the spatial distributions of stellar populations, we divide pixel stellar populations using the pixel color-color diagram and population synthesis models. As a result, we find that the pixel population distributions across the spiral arms agree with a compressing process by spiral density waves: dense dust \rightarrow newly-formed stars. The tidal interaction between NGC 5194 and NGC 5195 appears to enhance the star formation at the tidal bridge connecting the two galaxies. We find that the pixels corresponding to the central active galactic nucleus (AGN) area of NGC 5194 show a tight sequence at the bright-end of the pCMD, which are in the region of R ~ 100 pc and may be a photometric indicator of AGN properties.

description: Lightweight group meetings are opportunistic, ad hoc, or lightly planned gatherings characterized by the informal nature of their members and their tasks. Critically, they must be very easy to set up and maintain over time. We contribute the design of a system called Come Together, which supports lightweight, persistent meetings between distance-separated people. Its design is theoretically motivated by the Locales Framework, with features derived from the best of Instant Messengers and the Community Bar. The main motivation is that that any action must be simple and fast to do if it is to support lightweight group meetings. In particular, Come Together represents both people and their things as media items, which can be quickly brought together to form an ad hoc place. Places, which are persistent, can be presented in a variety of forms (e.g., as a stand-alone window, or as an element in a sidebar), with interaction mechanisms that let a person quickly adjust the degree of awareness he or she wishes to maintain of the place and its contents. A console collects all people, artifacts, and places in a manner akin to buddy lists, where these components can be used to rapidly compose the meeting place.

description: Highly magnetized neutron stars (NSs) are characterized by a bewildering range of astrophysical manifestations. Here, building on our simulations of the evolution of magnetic stresses in the NS crust and its ensuing fractures (Perna & Pons 2011), we explore in detail, for the middle-age and old NSs, the dependence of starquake frequency and energetics on the relative strength of the poloidal (B_p) and toroidal (B_tor) components. We find that, for B_p >~10^{14}G, since a strong crustal toroidal field B_tor B_p is quickly formed on a Hall timescale, the initial toroidal field needs to be B_tor >> B_p to have a clear influence on the outbursting behaviour.

description: In wireless sensor networks, cluster-based data gathering has been pursued as a means to achieve network scalability as well as energy efficiency. By dividing a network into clusters, data aggregation and compression can be conveniently implemented in each cluster resulting in significant reduction in overall network energy consumption. Although many clustering algorithms have been proposed in the literature for minimizing energy consumption in sensor networks, a comprehensive and systematic analysis of optimal clustering subject to inherent network attributes such as data correlation, node density, and distance to the sink is still lacking. In particular, existing clustering schemes are designed to form uniform clusters in the network, where, on average, clusters have the same size. In this paper, we exploit spatial data correlation present among sensor readings to form optimal-sized clusters that minimize the total energy cost of the network. We develop a generalized multi-region network model that captures the interplay between clustering and data correlation, and postulate that a heterogeneous clustering scheme, with larger clusters at further distances from the sink, is more energy-efficient than uniform clustering. Based on this model, we develop a distributed randomized clustering algorithm that generates optimal-sized non-uniform clusters throughout the network. Simulation results confirm the superiority of our novel algorithm against uniform clustering schemes.

description: We study the quark structure of the sigma meson through the decay of $D_1(2430)$ meson by constructing an effective Lagrangian for charmed mesons interacting with light mesons based on the chiral symmetry and heavy quark symmetry. Within the linear realization of the chiral symmetry, we include the P-wave charmed mesons ($D_1(2430)$, $D_0(2400)$) as the chiral partners of ($D^\ast$, $D$), and the light scalar mesons as the chiral partner of the pseudoscalar mesons. In the light meson sector, both the $q\bar{q}$ and $qq\bar{q}\bar{q}$ states are incorporated respecting their different U(1)$_A$ transformation properties. We predict the $D_1 \to Dππ$ decay width with two pions in the $I=0,\,l=0$ channel, which can be tested in the future experiment. We find that the width increases with the percentage of the $q\bar{q}$ content in the sigma meson.

title: New Paths of Attacks: Revealing the Adaptive Integration of Artificial Intelligence in Evolving Cyber Threats Targeting Social Media Users and Their Data
Creators: name: Teasley, Larry
Publisher: name: Old Dominion University Libraries
Year: 2023

description: The intersection between artificial intelligence tools and social media has opened doors to numerous opportunities and risks. This research delves into the escalating threat landscape in a society heavily dependent on social media. Despite the efforts by social media companies and cybersecurity professionals to mitigate cyber-attacks, the constant advancements of new technologies render social media platforms increasingly vulnerable. Malicious actors exploit generative AI to collect user data, enhancing cyber threats on social media. Notably, generative AI amplifies phishing attacks, disseminates false information, and propagates propaganda, posing substantial challenges to platform security. Ease access to large language models (LLMs) further complicates the distinction between fake and genuine accounts, as malicious actors employ learned techniques from summarized and translated text to masquerade human communication. This research explores the multiple challenges social media platforms face, including the ingrained human dependence on these platforms, the risk associated with user data, the integration of artificial intelligence, and the evolving landscape of deep fakes. Examining these challenges elucidates the profound implications for the public, emphasizing the critical need for effective countermeasures to safeguard the integrity of social media platforms in the face of these new paths of attacks.

description: This report describes and discusses the findings from a field study that was conducted at the Vancouver Aquarium to investigate how visitors explore and experience large horizontal multi-touch tables as part of public exhibition spaces. The study investigated visitors’ use of two different tabletop applications—the Collection Viewer and the Arctic Choices table—that are part of the Canada’s Arctic exhibition at the Vancouver Aquarium. Our findings show that both tabletop exhibits enhanced the exhibition in different ways. The Collection Viewer table evoked visitors curiosity by presenting visually interesting information and engaged by supporting lightweight, playful, and open-ended information exploration. The Arctic Choices table enabled visitors to explore a variety of information about environmental and political changes within the Arctic in depth by providing detailed data visualizations. The application triggered a lot of insightful discussions among visitors. Our study findings include a discussion of the factors that attracted visitors’ attention and triggered interaction with both tabletop exhibits, the character and duration of information exploration, general exploration strategies, and factors that triggered social and collaborative information exploration. We also discuss usability issues of both tabletop applications alongside possible solutions.

description: Using joint observations from Hinode/EIS and the Atmospheric Imaging Array (AIA) on the Solar Dynamics Observatory we explore the asymmetry of coronal EUV line profiles. We find that asymmetries exist in all of the spectral lines studied, and not just the hottest lines as has been recently reported in the literature. Those asymmetries indicate that the velocities of the second emission component are relatively consistent across temperature and consistent with the apparent speed at which material is being inserted from the lower atmosphere that is visible in the SDO/AIA images as propagating coronal disturbances. Further, the observed asymmetries are of similar magnitude (a few %) and width (determined from the RB analysis) across the temperature space sampled and in the small region studied. Clearly, there are two components of emission in the locations where the asymmetries are identified in the RB analysis, their characteristics are consistent with those determined from the SDO/AIA data. There is no evidence from our analysis that this second component is broader than the main component of the line.

Quality of service provisioning for multimedia transmissions in packet-switched wireless communication systems
Creators: name: Hui, Chen
Publisher: name: University of British Columbia
Year: 2010

description: This thesis covers several research problems in the area of multimedia transmissions over wireless communication systems. The objective is to enhance the quality of service (QoS) provisioning for multimedia transmissions over wireless communication systems. Recent advances in signal processing techniques have enabled wireless networks to have multi-packet reception (MPR) capability at the physical layer, where it is possible to receive more than one packet when concurrent transmissions occur. In this thesis, a multi-reservation, multiple access (MRMA) scheme for wireless multimedia networks, based on an MPR channel model, is proposed to differentiate the QoS provisioning for multimedia traffic and best effort traffic on MPR-enabled channels. Another advance in recent wireless technologies is the cross-layer optimization over wireless links. In this thesis, a cross-layer QoS provisioning method is proposed. Specifically, the data frame drop ratio (FDR) in the medium access control layer and the bit error rate (BER) in the physical layer are jointly optimized to provide a better data frame loss ratio (FLR) seen by the higher layers. In this thesis, a cross-layer enhanced scheduling (CEPS) method is proposed for providing QoS optimization for multimedia traffic in multi-code code-division multiple access (MC-CDMA) systems. CEPS also provides flexible fairness provisioning among different traffic flows. Then, the cross-layer QoS FLR in the MC-CDMA systems is further optimized by accounting for not only the predesigned QoS requirements, the historical QoS experienced, and the current buffer status, but also the statistical traffic models of different traffic flows. Results show that the system performance and the QoS provisioning can be greatly improved by the cross-layer QoS consideration and the proposed optimizations. The thesis also adopts the cross-layer QoS consideration in adaptive modulation and coding (AMC)-enabled wireless systems. A QoS-based cross-layer scheduling scheme (QoS-CLS) is proposed for AMC-based systems. It can guarantee the QoS provisioning for multimedia traffic flows and/or share the QoS among different traffic flows by making scheduling and coding/modulation decisions based on the buffer status, traffic status, channel status, and other information for different traffic flows. Results show that QoS-CLS can greatly enhance the system performance.

Fair and Efficient Scheduling in Wireless Networks with Successive Interference Cancellation

Year: 2010
Subjects: subject: Successive interference cancellation
subject: scheduling

subject: Uplink scheduling, wireless networks

description: This paper considers the problem of uplink scheduling in wireless networks supporting successive interference cancellation (SIC) at the physical layer. By allowing concurrent interfering transmissions, SIC enables multi-packet reception at the receiver resulting in increased network throughput. Specifically, we consider maximum throughput scheduling and proportional fair scheduling problems and study optimal and heuristic algorithms for these problems. We prove that the maximum throughput scheduling problem is NP-hard and develop a throughput efficient polynomial time greedy algorithm for the problem. While being throughput efficient, the maximum throughput scheduling can lead to highly unfair rates among the users. The proportional fair scheduling, on the other hand, is not throughput optimal but achieves proportional fairness among the users. For scheduling multiple users in a single time-slot, we show that there exists an algorithm that solves the proportional fair scheduling problem in polynomial time. For scheduling in multiple time-slots, we develop a greedy algorithm that computes a highly fair schedule in polynomial time. Numerical results are also provided to show the utility and efficiency of the proposed scheduling algorithms in various simulated networks.

description: We perform a systematic analysis of exclusive hadronic channels in e+e- collisions at centre-of-mass energies between 2.1 and 2.6 GeV within the statistical hadronization model. Because of the low multiplicities involved, calculations have been carried out in the full microcanonical ensemble, including conservation of energy-momentum, angular momentum, parity, isospin, and all relevant charges. We show that the data is in an overall good agreement with the model for an energy density of about 0.5 GeV/fm^3 and an extra strangeness suppression parameter gamma_S ~ 0.7, essentially the same values found with fits to inclusive multiplicities at higher energy.

I employed a multimodal discourse analysis research method. Combining cognitive semiotics and the Halliday model of language ecology, this paper constructed a symbolic ecological niche mechanism of ecological culture. I attempted to explore the interactive relationship between the affordance of ecological culture and the symbolic ecological niche. The research results show that this picturebook represented environmental and social affordance through the interaction between ecological culture participants and the natural and human environments. Meanwhile, from the perspective of cognitive semiotics, codes, metaphors, symbolization, context, and symbolism, this sample domain is related to the modalities of text, image, and sound, interacting with diverse affordance properties in natural, social, and cultural environments. Finally, I constructed a symbolic ecological niche mechanism of ecological culture that dynamically links the collection of symbolic environments, cognitive symbol sets, and symbolic modal sets based on the realistic portrayal of picture books.

description: An important technique to reduce the contention on the limited bandwidth of wireless channels between mobile units and base stations is caching frequently accessed data items. In the literature, two approaches were proposed for cache consistency: Stateful and Stateless. In the Stateful approach, the server has to keep information about all the mobile units in its cell. On the other hand, in the stateless approach, the server does not store any information about clients. In this paper, we propose a hybrid cache consistency approach which combines the advantages of both Stateless and Stateful approaches; our approach has several characteristics in common with the Scalable Algorithm for Cache Consistency Scheme “SACCS”, which has been reported to have advantages compared to some major previous algorithms, including TimeStamps, Signatures, Amnesic Terminals and Asynchronous Stateful. The proposed approach reduces the side-effect of the sleep-wakeup patterns, and uses new communication messages intended to invalidate only the entries changed during the sleep time. Further, we propose a better replacement policy for the mobile unit cache, which considers the size of the removed entry to improve channel utilization. Experimental results show that the proposed approach increases the mobile cache hit, reduces the delay time of queries and reduces traffic in both uplink and downlink channels.

description: Exercise is vital to maintaining good health, but many people do not work out regularly or often enough. There are many reasons why this is so, but one important factor is the lack of will. Physical exercise is often perceived by inactive people as tiring, repetitive and boring, and generally unattractive. Psychological motivation and emotional incentive can play an important role in whether a person would head for a jog or remain in front of their computer or head for the fridge. We propose a virtual pet, Mootchi, which will provide users with an emotional incentive for exercising. Mootchi engages users by expressing sadness from time to time, and asking them to care for it, and help Mootchi regain happiness. Mootchi becomes sad if it’s static and idle for too long, and requires physical movement in order to feel happy again. In order to make the emotional state of Mootchi explicit and unavoidable Mootchi is embodied in a portable form, and is being constantly projected as part of the user physical environment. This work-in-progress report outlines our prototype implementation and initial findings based on a design critique.
Relationship-Based Access Control Policies and Their Policy Languages

description: The Relationship-Based Access Control (ReBAC) model was recently proposed as a general-purpose access control model. It supports the natural expression of parameterized roles, the composition of policies, and the delegation of trust. Fong proposed a policy language that is based on Modal Logic for expressing and composing ReBAC policies. A natural question is whether such a language is representationally complete, that is, whether the language is capable of expressing all ReBAC policies that one is interested in expressing. In this work, we argue that the extensive use of what we call Relational Policies is what distinguishes ReBAC from traditional access control models. We show that Fong’s policy language is representationally incomplete in that certain previously studied Relational Policies are not expressible in the language. We introduce two extensions to the policy language of Fong, and prove that the extended policy language is representationally complete with respect to a well-defined subclass of Relational Policies.
Digitales Besuchermanagement – Erste Handlungsansätze für große Herausforderungen

Year: 2023

description: Die Corona-Pandemie hat eindrücklich die Schwächen von Besuchermanagementstrategien auf Destinationsebene aufgezeigt, sofern diese überhaupt existierten. Staus, überfüllte Parkplätze und eine abnehmende Gästeakzeptanz seitens der lokalen Bevölkerung als Folge der pandemisch induzierten Reise- und Ausflugsströme haben bundesweit das Thema Besucherlenkung verstärkt auf die operative Agenda von Destinationsmanagementorganisationen (DMOs) gesetzt. Als wichtige Hebel werden hier richtigerweise digitale Besucherlenkungsmaßnahmen in den Fokus gerückt. Digitale Touchpoints eröffnen zunehmend Möglichkeiten, mit den (potentiellen) Gästen zu kommunizieren und je nach Bedarf über das Bereitstellen relevanter Informationen Besucherströme zeitlich oder räumlich zu lenken.

On Accuracy of Community Structure Discovery Algorithms

description: Community structure discovery in complex networks is a quite challenging problem spanning many applications in various disciplines such as biology, social network and physics. Emerging from various approaches numerous algorithms have been proposed to tackle this problem. Nevertheless little attention has been devoted to compare their efficiency on realistic simulated data. To better understand their relative performances, we evaluate systematically eleven algorithms covering the main approaches. The Normalized Mutual Information (NMI) measure is used to assess the quality of the discovered community structure from controlled artificial networks with realistic topological properties. Results show that along with the network size, the average proportion of intra-community to inter-community links is the most influential parameter on performances. Overall, "Infomap" is the leading algorithm, followed by "Walktrap", "SpinGlass" and "Louvain" which also achieve good consistency.

description: We propose a wavelength-saving topology of quantum key distribution(QKD) network based on passive optical elements, and report the field test of this network on the commercial telecom optical fiber. In this network, 5 nodes are supported with 2 wavelengths, and every two nodes can share secure keys directly at the same time. All QKD links in the network operate at the frequency of 20 MHz. We also characterized the insertion loss and crosstalk effects on the point-to-point QKD system after introducing this QKD network.

Access Control Policy Analysis with a Visualization Tool for Social Network Systems

Year: 2011
Subjects: subject: Security
subject: Human Factors
subject: Access control, Reflective policy assessment, Visualization, Usability

description: Understanding privacy implications of access control policies is a complex task for the users of social network systems. Users need tool support to articulate on access scenarios and perform policy analysis. In this work, we develop a prototypical tool for reflective policy assessment (RPA) – a process in which a user examines her profile from the viewpoint of another user in her extended neighborhood in the social graph. Since an unrestricted view of one's extended neighborhood may compromise the privacy of others, our visualization tool approximates the extended neighborhood of a user in such a way that policy assessment can still be conducted in a meaningful manner, while the privacy of other users is preserved. We verify the utility and usability of our tool in a within-subject user study.
Collocated Interaction with Flying Robots

description: We introduce a socially motivated interaction technique with collocated flying robots (a quadrotor in our current prototype). Instead of the traditional remote interaction controllers often used when interacting with flying robots and UAVs, we explore the collocated interaction space and suggest a direct interaction technique motivated by social human-robot interaction themes. Our approach is inspired by the types of interaction humans have with birds, specifically falconeering, and is facilitated by gestures-based interaction, while the user is within the field of view of the flying robot. This paper outlines our research goals, task examples, and our overall design approach. The paper also discusses our current prototyping efforts, as well as a preliminary evaluation of our approach, performed through two design critiques, studying our collocated interaction technique concept, and its potential, drawbacks and benefits for users.
