On energy-efficient data gathering in sensor networks
Creators: name: Dhar, Debojit
Publisher: name: University of British Columbia

description: Wireless sensor networks (WSNs) are becoming increasingly important as they provide an ideal platform for monitoring and controlling physical environments. Starting from small match-box sized nodes to tiny coin-like sensors a WSN promises to be the most ubiquitous information gathering system produced. Being tiny enables ubiquitous and pervasive sensing. However, this form factor comes at the cost of severe resource constraints for the sensor nodes. The nodes can accommodate only a certain amount of energy in the form of batteries and can store and process only a small amount of data due to its crippled size. Due to this reason, sensor networks cannot host more sophisticated applications and the mean time to failure, due to nodes running out of energy, is also low. These are probably the main reasons why sensor networks have not reached their expected potential. This thesis is an effort to alleviate the energy problem of sensor nodes. We attempt to solve the problem using different data and user centric models which can lead to a multi-fold increase of life for the sensors. Most of the research till date has aimed at micro-adjustments in the sensor hardware and software in order to improve performance. These techniques, though beneficial, increase complexity, and are sometimes difficult to implement. The thesis demonstrates simple techniques that can significantly improve energy-savings over and above the micro-adjustment techniques. The thesis takes a radical point of view and looks at higher level primitives that can be modified for certain applications. This thesis provides two energy reduction techniques. The first technique involves aggressive duty-cycling of sensors while maintaining connectivity and coverage followed by reconstruction at the base station. Significant gains can be achieved when the sensed environment has correlation between sensor readings. The second technique involves sampling interval scheduling depending on the utilization of the sampled data based on user queries. While the first method ensures correct reproduction of the sensed environment, while reducing the burden on individual sensors, the second method provides an optimal sampling frequency that regulates energy consumption depending on user demands.

description: Autor poświęca Doktorom J. Kremisowi i J. Strzebinczykowi opracowanie dotyczące problematyki prawnej rozumienia pojęcia sposobu wyrażenia utworów architektonicznych na tle współcześnie występujących zjawisk polegających na upowszechnieniu się środków wyrazu typowych dla architektury w działalności twórczej innych sztuk wizualnych. Efektem tego zjawiska jest swoiste zacieranie się różnic wyrazu, tradycyjnie przeciwstawianych sobie rodzajów utworów w dziedzinie twórczości operującej wizualnymi środkami wyrazu. Wskazuje na zasadność konstruowania pojęcia prawnego utworu architektonicznego z uwzględnieniem przede wszystkim funkcji prawnej takiego zabiegu. W szczególności dochodzi do wniosku o konieczności uwzględniania w tej definicji – „użytkowego” charakteru utworów architektonicznych, a więc występowania cech innych niż te, którymi definiuje się „architektoniczność” na gruncie estetyki i historii sztuki. Podejmuje też próbę uzasadnienia prawnego dla oceny, iż powstanie utrwalenia w postaci konkretnego obiektu nie jest warunkiem powstania ochrony prawnej utworów architektonicznych, choć może wpływać na jej „intensywność” w odniesieniu do takich niezrealizowanych przedmiotów.

description: Inspired by work on Stackelberg security games, we introduce Stackelberg planning, where a leader player in a classical planning task chooses a minimum-cost action sequence aimed at maximizing the plan cost of a follower player in the same task. Such Stackelberg planning can provide useful analyses not only in planning-based security applications like network penetration testing, but also to measure robustness against perturbances in more traditional planning applications (eg with a leader sabotaging road network connections in transportation-type domains). To identify all equilibria–exhibiting the leader's own-cost-vs.-follower-cost tradeoff–we design leader-follower search, a state space search at the leader level which calls in each state an optimal planner at the follower level. We devise simple heuristic guidance, branch-and-bound style pruning, and partial-order reduction techniques for this setting. We run experiments on Stackelberg variants of IPC and pentesting benchmarks. In several domains, Stackelberg planning is quite feasible in practice.

PRIMA: Privacy-Preserving Identity and Access Management at Internet-Scale

description: The management of identities on the Internet has evolved from the traditional approach (where each service provider stores and manages identities) to a federated identity management system (where the identity management is delegated to a set of identity providers). On the one hand, federated identity ensures usability and provides economic benefits to service providers. On the other hand, it poses serious privacy threats to users as well as service providers. The current technology, which is prevalently deployed on the Internet, allows identity providers to track the user's behavior across a broad range of services. In this work, we propose PRIMA, a universal credential-based authentication system for supporting federated identity management in a privacy-preserving manner. Basically, PRIMA does not require any interaction between service providers and identity providers during the authentication process, thus preventing identity providers to profile users' behavior. Moreover, throughout the authentication process, PRIMA provides a mechanism for controlled disclosure of the users' private information. We have conducted comprehensive evaluations of the system to show the feasibility of our approach. Our performance analysis shows that an identity provider can process 1,426 to 3,332 requests per second when the key size is varied from 1024 to 2048-bit, respectively.

description: We figure out that the ground state of a multiple-spin exchange model applicable to thin films of solid 3He possesses an octahedral spin nematic order. In the presence of magnetic field, it is deformed into an antiferro-quadrupolar order in the perpendicular spin plane, in which lattice Z3 rotational symmetry is also broken. Furthermore, this system shows a narrow magnetization plateau at half, m/m_{sat}=1/2, which resembles recent magnetization measurement [H. Nema et al., Phys. Rev. Lett. 102, 075301 (2009)].

description: Security in the Internet has historically been added post-hoc, leaving services like email, which, after all, is used by 3.7 billion users, vulnerable to large-scale surveillance. For email alone, there is a multitude of proposals to mitigate known vulnerabilities, ranging from the introduction of completely new protocols to modifications of the communication paths used by big providers. Deciding which measures to deploy requires a deep understanding of the induced benefits, the cost and the resulting effects. This paper proposes the first automated methodology for making formal deployment assessments. Our planning algorithm analyses the impact and cost-efficiency of different known mitigation strategies against an attacker in a formal threat model. This novel formalisation of an infrastructure attacker includes routing, name resolution and application level weaknesses. We apply the methodology to a large-scale scan of the Internet, and assess how protocols like IPsec, DNSSEC, DANE, SMTP STS, SMTP over TLS and other mitigation techniques like server relocation can be combined to improve the confidentiality of email users in 45 combinations of attacker and defender countries and nine cost scenarios. This is the first deployment analysis for mitigation techniques at this scale.

description: The decreasing costs of molecular profiling has fueled the biomedical research community with a plethora of new types of biomedical data, enabling a breakthrough towards a more precise and personalized medicine. However, the release of these intrinsically highly sensitive data poses a new severe privacy threat. While biomedical data is largely associated with our health, there also exist various correlations between different types of biomedical data, along the temporal dimension, and also in-between family members. However, so far, the security community has focused on privacy risks stemming from genomic data, largely overlooking the manifold interdependencies between other biomedical data. In this paper, we present a generic framework for quantifying the privacy risks in biomedical data taking into account the various interdependencies between data (i) of different types, (ii) from different individuals, and (iii) at different time. To this end, we rely on a Bayesian network model that allows us to take all aforementioned dependencies into account and run exact probabilistic inference attacks very efficiently. Furthermore, we introduce a generic algorithm for building the Bayesian network, which encompasses expert knowledge for known dependencies, such as genetic inheritance laws, and learns previously unknown dependencies from the data. Then, we conduct a thorough inference risk evaluation with a very rich dataset containing genomic and epigenomic data of mothers and children over multiple years. Besides effective probabilistic inference, we further demonstrate that our Bayesian network model can also serve as a building block for other attacks. We show that, with our framework, an adversary can efficiently identify the parent-child relationships based on methylation data with a success rate of 95%.

description: Hashtag has emerged as a widely used concept of popular culture and campaigns, but its implications on people’s privacy have not been investigated so far. In this paper, we present the first systematic analysis of privacy issues induced by hashtags. We concentrate in particular on location, which is recognized as one of the key privacy concerns in the Internet era. By relying on a random forest model, we show that we can infer a user’s precise location from hashtags with accuracy of 70% to 76%, depending on the city. To remedy this situation, we introduce a system called Tagvisor that systematically suggests alternative hashtags if the user-selected ones constitute a threat to location privacy. Tagvisor realizes this by means of three conceptually different obfuscation techniques and a semantics-based metric for measuring the consequent utility loss. Our findings show that obfuscating as little as two hashtags already provides a near-optimal trade-off between privacy and utility in our dataset. This in particular renders Tagvisor highly time-efficient, and thus, practical in real-world settings.

Low-temperature resistivity measurements revealed a sample dependent temperature exponent below 10 K, which for the samples with highest quality deviates from a linear-in-T behaviour.

Complementing this program, SNO+ will also search for 150Nd (5.6% abundance) neutrinoless double beta decay, loading the liquid scintillator with 0.1% of natural Neodymium. After a review of the general SNO+ setup, the physics of the solar neutrino phase will be presented.

description: Analyzing information flow is central in assessing the security of applications. However, static and dynamic analyses of information flow are easily challenged by non-available or obscure code. We present a lightweight mutation-based analysis that systematically mutates dynamic values returned by sensitive sources to assess whether the mutation changes the values passed to sensitive sinks. If so, we found a flow between source and sink. In contrast to existing techniques, mutation-based flow analysis does not attempt to identify the specific path of the flow and is thus resilient to obfuscation. In its evaluation, our MUTAFLOW prototype for Android programs showed that mutation-based flow analysis is a lightweight yet effective complement to existing tools. Compared to the popular FLOWDROID static analysis tool, MUTAFLOW requires less than 10% of source code lines but has similar accuracy; on 20 tested real-world apps, it is able to detect 75 flows that FLOWDROID misses.
Radio fingerprinting for anomaly detection using federated learning in LoRa-enabled industrial internet of things

Subjects: Engineering

description: Long Range (LoRa) communications are gaining popularity in the Industrial Internet of Things (IIoT) domain due to their large coverage and high energy efficiency. However, LoRa-enabled IIoT networks are susceptible to cyberattacks mainly due to their wide transmission window and freely operated frequency band. This has led to several categories of cyberattacks. However, existing anomaly detection systems are inefficient in detecting particularly impersonation attacks due to the dense deployment, heterogeneous IIoT devices and manufacturers involved. In this work, we introduce Hawk, a distributed anomaly detection system for detecting compromised devices in LoRa-enabled IIoT. Hawk first measures a device-type specific physical layer feature, Carrier Frequency Offset (CFO) and then leverages the CFO for fingerprinting the device, and consequently detecting anomalous deviations in the device’s CFO behavior, potentially caused by adversaries. To aggregate the device-type specific CFO behavior profile efficiently, Hawk uses federated learning, a distributed machine learning approach. To the best of our knowledge, Hawk is the first to utilise a federated learning method for anomaly-based intrusion detection in LoRa-enabled IIoT. We perform extensive experiments on a real-world dataset collected using 60 LoRa devices, primarily to assess the effectiveness of Hawk against emerging new and unknown attacks. The results show that Hawk improves the detection accuracy by more than 8% compared to the state-of-the-art solutions. Additionally, Hawk reduces the storage overhead by more than 40%, and exhibits significant robustness against cyberattack

Decarbonization of buildings and other flexible loads through electrification will present new challenges to the nation's infrastructure and operational status quo. Existing building loads currently served by fossil fuels will require electrification, including end uses not previously associated with building energy infrastructure such as electric vehicle charging. In many cases, the existing infrastructure cannot accommodate the new loads according to current regulations and upgrading that infrastructure may not always be feasible— especially for low-income families. State-of-the-art grid-responsive control strategies have been shown to provide significant savings for the customer, valuable grid services to utilities/grid operators, and are likely the lowest cost source of grid peak load and carbon pollution reductions. Although emissions reductions are typically a secondary objective in these strategies, they can be reformulated to directly optimize for carbon emissions reductions. Not only will carbon-aware control allow the full emissions reduction potential to be realized, it could also reduce the pressure on existing infrastructure. In this session, panelists from the U.S. Department of Energy, national laboratories, industry, and academia will discuss the current efforts on addressing the infrastructure constraint challenges, support of affordable home electrification, and advanced controls strategies for controlling flexible loads.

description: Five effects of reactivated basement structure are proposed for the Devonian strata of the Western Canada Sedimentary Basin: Precambrian topography and structural heredity, modification of systems tracts, synsedimentary deformation structures, modification of preservational geometries and tectonic diagenesis. Significant basement structures have been identified in the Strachan area of west-central Alberta and the Buffalo Lake - Red Deer River area of east-central Alberta, through an integration of drill core data, isotope data, high resolution aeromagnetic data, aerial photographs and reflection seismic data. These structures, which include near-vertical mfaults bounding fault blocks, synforms and antiforms, have been reactivated through time in response to both far-field and intraplate stresses. To substantiate the structural interpretation, a key lithological marker bed has been identified in the cored Devonian units of the Strachan area; this unique chemical laminite unit was originally flat-lying and of broad areal extent. This unit now shows substantial vertical offset (298m) between wells, and has been identified in wells as far apart as 50 km. Brittle deformation features observed in Frasnian and Famennian aged rocks (Leduc to Stettler formations) include shear fractures, tension gashes and brecciation. Fractures have commonly undergone solution-enhancement and contribute substantially to reservoir porosity and permeability. Fracture type and density vary with proximity to the large basement structures, as do the occurrence of brecciated intervals that may function as sealing units. Frasnian subsurface units are compared to the Frasnian Cairn Formation exposed in upper portions of the avalanche chutes south of Canmore, Alberta in the Canadian Rocky Mountains. The Westem Canada Sedimentary Basin is structured; this has affected the rocks through geological time. Many carbonate features previously identified as biologic "reefs" are actually structural preservational remnants. This research will enhance reservoir characterization models as well as contribute to the elucidation of the structural history of the Westem Canada Sedimentary Basin.

With climate change, we are experiencing more frequent and more severe extreme weather, such as storms, extreme cold and extreme heat. On the other front, with energy de-carbonization, significant amount of weather dependent renewable resources, such as wind and solar, have been penetrating in the grid and becoming the dominant resource types.  Therefore, grid operation is now more relying on weather information than decade ago, be it winter storm, heat wave, solar eclipse, to plan and prepare system correspondingly, maintaining grid reliability and ensuring grid resilience. At this panel, industry experts will share their experiences and challenges from aspects of operation, planning and markets.

description: Motivated by studying the Unitary Dual Problem, a variation of Kazhdan-Lusztig polynomials was defined in [Yee08] which encodes signature information at each level of the Jantzen filtration. These so called signed Kazhdan-Lusztig polynomials may be used to compute the signatures of invariant Hermitian forms on irreducible highest weight modules. The key result of this paper is a simple relationship between signed Kazhdan-Lusztig polynomials and classical Kazhdan-Lusztig polynomials: signed Kahzdan-Lusztig polynomials are shown to equal classical Kazhdan-Lusztig polynomials evaluated at $-q$ rather than $q$ and multiplied by a sign. This result has applications to finding the unitary dual for real reductive Lie groups since Harish-Chandra modules may be constructed by applying Zuckerman functors to highest weight modules.

Ambitious goals have been set world-wide for decarbonization of the transport sector. Electric vehicles currently offer the most viable alternative to internal combustion vehicles across a range of end-uses. In 2022 it is estimated that there were 18 million plug-in electric vehicles in use globally, representing a 10-fold increase since 2016. Charging of electric vehicles will add significant load to power systems, particularly to low voltage distribution networks. However, electric vehicle chargers could also provide new levels of controllability to power demand  e.g., through load shifting, ancillary services, or market participation. This session will analyze various aspects of the integration of electrified transport into power systems — considering both economic and technical challenges. The panelists will cover a range of transport scales, from residential vehicle charging to commercial fleet management.

description: From the perspective of the statistical fluctuation theory, we explore the role of the thermodynamic geometries and vacuum (in)stability properties for the topological Einstein-Yang-Mills black holes. In this paper, from the perspective of the state-space surface and chemical Wienhold surface, we provide the criteria for the local and global statistical stability of an ensemble of topological Einstein-Yang-Mills black holes in arbitrary spacetime dimensions $D\ge 5$. Finally, as per the formulations of the thermodynamic geometry, we offer a parametric account of the statistical consequences in both the local and global fluctuation regimes of the topological Einstein-Yang-Mills black holes.

description: A detailed assessment of a pasture’s functioning based on soil properties characterization, floristic composition, and ‘functional summary’ by evaluating competitor–stress tolerator–ruderal (CSR) strategies is provided for a doline in Central Italian Alps. A floristic survey was carried out at 35 sampling points, representative of the main topographic features, soil and vegetation types; the functional profile at the community level was evaluated by assessing for each species its Grime’s CSR strategy; each point was characterized through soil profiles and topsoil (0–10 cm) sampling; pH, soil organic carbon and total nitrogen, available P, soil humus fraction, root density, bulk density, water content, and available water capacity were determined. Our study showed i) a strong relationship between vegetation, soil properties, topography, and grazing; ii) a prevalence of stress-tolerant strategies; iii) the ability of plant strategy variation to reflect the ecological parameters; and iv) the vegetation potentiality to be an indicator of environmental spatial variability.
The function of ABCF1 in immunity and mouse development.

description: ABCF1 is an ABC (ATP binding cassette) transporter protein that lacks trans-membrane domains. Gene expression of ABCF1 has been shown to increase upon tumour necrosis factor alpha (TNFα) stimulation [1]. This is significant as TNFα is a pro-inflammatory cytokine produced by macrophages and T cells and has a number of functions in the immune response [2]. ABCF1 is thought to function in translational initiation by interacting with the eukaryotic initiation factor 2 (eIF2) [3]. We have determined that ABCF1 is an essential gene in development by the generation and characterization of mice that have a gene trap insertion in the ABCF1 gene, which terminates the expression of the ATP binding cassettes. Homozygous ABCF1 knock-out (ABCF1-/-) mice are embryonic lethal at 3.5 days post coitus (dpc) while heterozygous ABCF1 knock-out (ABCF1+/-) mice appear to be developmentally normal. This thesis utilizes the ABCF1 gene trapped mouse model which contains a β-geo (β-galactosidase /neomycin) reporter gene in the ABCF1 gene to examine the endogenous ABCF1 promoter expression. This allows us to concurrently observe the activity of the ABCF1 promoter in all tissues through sectioning and X-Gal staining. This analysis provides further insight into the physiological function of ABCF1 by identifying the tissues and cell types that have the highest levels of promoter activity. Interestingly, ABCF1 appeared to be expressed in the marginal zone of the spleen and areas surrounding the lymphoid follicles. Macrophages, which were isolated from spleens of ABCF1+/- mice, were found to be hyper-responsive to stimulation by TLR ligands, particularly LPS, while macrophages derived from the bone marrow were found to be hypo-responsive. When challenged with LPS, ABCF1+/- mice produced altered cytokine production compared to their wild-type controls. Upon challenge with Listeria monocytogenes, ABCF1+/- mice succumbed to infection sooner than their ABCF1+/+ littermates. Taken together, these data indicate that ABCF1 is necessary for survival and development and likely has a role in the regulation of cytokines. Thus ABCF1 may play a significant role in regulating inflammation and pathogen induced “cytokine storm”.

description: We report results of inelastic-neutron-scattering measurements of low-energy spin-wave excitations in two structurally distinct families of iron-pnictide parent compounds: Na(1-δ)FeAs and BaFe2As2. Despite their very different values of the ordered magnetic moment and Néel temperatures, T_N, in the antiferromagnetic state both compounds exhibit similar spin gaps of the order of 10 meV at the magnetic Brillouin-zone center. The gap opens sharply below T_N, with no signatures of a precursor gap at temperatures between the orthorhombic and magnetic phase transitions in Na(1-δ)FeAs. We also find a relatively weak dispersion of the spin-wave gap in BaFe2As2 along the out-of-plane momentum component, q_z. At the magnetic zone boundary (q_z = 0), spin excitations in the ordered state persist down to 20 meV, which implies a much smaller value of the effective out-of-plane exchange interaction, J_c, as compared to previous estimates based on fitting the high-energy spin-wave dispersion to a Heisenberg-type model.

Practical Test Dependency Detection

description: Regression tests should consistently produce the same outcome when executed against the same version of the system under test. Recent studies, however, show a different picture: in many cases simply changing the order in which tests execute is enough to produce different test outcomes. These studies also identify the presence of dependencies between tests as one likely cause of this behavior. Test dependencies affect the quality of tests and of the correlated development activities, like regression test selection, prioritization, and parallelization, which assume that tests are independent. Therefore, developers must promptly identify and resolve problematic test dependencies. This paper presents PRADET, a novel approach for detecting problematic dependencies that is both effective and efficient. PRADET uses a systematic, data-driven process to detect problematic test dependencies significantly faster and more precisely than prior work. PRADET scales to analyze large projects with thousands of tests that existing tools cannot analyze in reasonable amount of time, and found 27 previously unknown dependencies.
