Packet Classification Using Growing Hierarchical Self-Organized Map
Creators: name: Montagna, Marco
Publisher: name: University of Illinois at Chicago
Year: 2019
Subjects: Uncategorized

description: The main goal of this thesis titled ”Packet Classification using Growing Hierarchical Self- Organizing Map” is to validate the possibility of using a new approach for a well know problem. The core idea is to present a possible implementation of a Growing Hierarchical Self-Organized Map (GH-SOM) for use in packet classification in the context of software-defined networking (SDN). SDN applications are characterized by frequent network configuration updates on-the-fly and a large number of rules thereby requiring a highly flexible packet classification mechanism. Moreover, as network bandwidths continue to grow, a high-performance packet classification is imperative. Today’s technology adopted for packet classification does not scale well in throughput and power consumption as number of rules increase. The main change proposed in this implemen- tation is to move all the complexity to an offline phase, train a modeled neural network and exploit its properties to provide a more efficient solution for packet classification during run time. Different input space and different parameters have been tested for training the network; multiple simulations have been performed in order to find the best solution to this problem. The work proposed consists of a trained neural network that classifies the rules of a given data-set, then input packets are applied and rule with highest priority is determined. Multiple simulation has been carried out for finding the best feature map for the different layer of the GH-SOM structure, in order to provide the best accuracy in every application. The MATLAB code was designed to give the possibility to the designer to easily adjust the training parameters of the neural network in order to provide a general implementation of the structure which can be adapted in multiple situations.
Explainable-by-Design Deep Learning

Publisher: name: Lancaster University
Year: 2022

description: Machine learning, and more specifically, deep learning, have attracted the attention of media and the broader public in the last decade due to its potential to revolutionize industries, public services, and society. Deep learning achieved or even surpassed human experts’ performance in terms of accuracy for different challenging problems such as image recognition, speech, and language translation. However, deep learning models are often characterized as a “black box” as these models are composed of many millions of parameters, which are extremely difficult to interpret by specialists. Complex “black box” models can easily fool users unable to inspect the algorithm’s decision, which can lead to dangerous or catastrophic events. Therefore, auditable explainable AI approaches are crucial for developing safe systems, complying with regulations, and accepting this new technology within society. This thesis tries to answer the following research question: Is it possible to provide an approach that has a performance compared to a Deep Learning and the same time has a transparent structure (non-black box)? To this end, it introduces a novel framework of explainable- by-design Deep Learning architectures that offers transparency and high accuracy, helping humans understand why a particular machine decision has been reached and whether or not it is trustworthy. Moreover, the proposed prototype-based framework has a flexible structure that allows the unsupervised detection of new classes and situations. The approaches proposed in thesis have been applied to multiple use cases, including image classification, fairness, deep recursive learning interpretation, and novelty detection.

Guidelines and calculation methods for  Lifecycle Environmental Impact  Assessment of Plus Energy Buildings
Creators: name: Di Bari, Roberta
Publisher: name: Zenodo
Year: 2025

description: This document aims to collect and report the results of the activities ongoing within the EU-funded Cultural-E project (under grant agreement No. 870072). As a prior result of the Cultural-E activities, a document has been prepared, in which the guidelines and calculation methods for carrying out environmental impact assessment on Plus Energy Buildings (PEBs) are outlined. The document is targeted to building developers and provides the audience with an operative methodology for dealing with Life Cycle Assessment (LCA), in compliance with standards ISO 14040 [1]. ISO 14044 [2]. For the compilation of the guidelines, core rules for the lifecycle modelling and impact calculation methods have been considered also specifications for buildings and building products, provided by EN 15804 [3], EN 15643 [4] and EN 15978 [5]. Task 4.5 of project Cultural-E demonstrated in fact the need for an adaptation and clear specification of LCA analyses for PEBs’ systems. This is mostly due to complexity of workflows and data to be handled as well as the novelty of the investigated systems. This document presents therefore to building developers a framework and, consequently, a procedure for LCA analyses of systems designed and developed forPlus Energy Buildings (PEBs).Such a procedure allows for a clear establishment of the LCA goal and scope. The PEBs systems are while evaluate through a bottom up approach, which, depending on the goal and scope of the analysis, extracts relevant information from specific outcome and finally proceed with the Life Cycle Inventory (LCI) and environmental impacts assessment. For a correct results’ derivation, it is important to choose and agree on adequate lifecycle modelling tools and match the collected information with suitable environmental datasetsIn addition to this, the report contains further outcomes coming from the abovementioned activities.The assessment of PEBs’ technologies (in this instance, Active Window System – AWS, NORDIC® ECO smart air movement, Packed Heat Pump – PHP and the High-capacity Hybrid Storage system – HCHS) is targeted to products developers. It serves as a reference for the evaluation of the environmental potential of such components and the identification of optimization potential.

The parametric LCA modelling of PEBs’ climate and cultural tailored solution sets is while addressed to building developers. It highlights advantages and challenges to be handled while designing PEBs in specific climate and cultural contexts. In this respect, it can be used within the project also as a reference for the next upcoming steps and especially for the lifecycle analyses of the designed demo cases.

description: Wireless information-centric networks consider storage as one of the network primitives, and propose to cache data within the network in order to improve latency and reduce bandwidth consumption. We study the throughput capacity and latency in an information-centric network when the data cached in each node has a limited lifetime. The results show that with some fixed request and cache expiration rates, the order of the data access time does not change with network growth, and the maximum throughput order is not changing with the network growth in grid networks, and is inversely proportional to the number of nodes in one cell in random networks. Comparing these values with the corresponding throughput and latency with no cache capability (throughput inversely proportional to the network size, and latency of order $\sqrt{n}$ and the inverse of the transmission range in grid and random networks, respectively), we can actually quantify the asymptotic advantage of caching. Moreover, we compare these scaling laws for different content discovery mechanisms and illustrate that not much gain is lost when a simple path search is used.

description: We report on the discovery of 41 new pulsating sources in the data of the Chandra Advanced CCD Imaging Spectrometer, which is sensitive to X-ray photons in the 0.3-10 keV band. The archival data of the first 15 years of Chandra observations were retrieved and analysed by means of fast Fourier transforms, employing a peak-detection algorithm able to screen candidate signals in an automatic fashion. We carried out the search for new X-ray pulsators in light curves with more than 50 photons, for a total of about 190,000 lightcurves out of about 430,000 extracted. With these numbers, the ChAndra Timing Survey at Brera And Roma astronomical observatories (CATS@BAR) - as we called the project - represents the largest ever systematic search for coherent signals in the classic X-ray band. More than 50 per cent of the signals were confirmed by further Chandra (for those sources with two or more pointings), XMM-Newton or ROSAT data. The period distribution of the new X-ray pulsators above about 2,000s resembles that of cataclysmic variables, while there is a paucity of sources with shorter period and low fluxes. Since there is not an obvious bias against these detections, a possible interpretation is in terms of a magnetic gating mechanism in accreting neutron stars. Finally, we note that CATS@BAR is a living project and the detection algorithm will continue to be routinely applied to the new Chandra data as they become public. Based on the results obtained so far, we expect to discover about three new pulsators every year.

description: For a given Lovelock order $N$, it turns out that static fluid solutions of the pure Lovelock equation for a star interior have the universal behavior in all $n\geq 2N+2$ dimensions relative to an appropriately defined variable and the Vaidya-Tikekar parameter $K$, indicating deviation from sphericity of $3$-space geometry. We employ the Buchdahl metric ansatz which encompasses almost all the known physically acceptable models including in particular the Vaidya-Tikekar and Finch-Skea. Further for a given star radius, the constant density star, always described by the Schwarzschild interior solution, defines the most compact state of distribution while the other end is marked by the Finch-Skea model, and all the other physically tenable models lie in between these two limiting distributions.

On the prospects of gamma-ray burst detection in the TeV band

Year: 2016
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: A gamma-ray burst (GRB) jet running into an external medium is expected to generate luminous GeV-TeV emission lasting from minutes to several hours. The high-energy emission results from inverse Compton upscattering of prompt and afterglow photons by shock-heated {\it thermal} plasma. At its peak the high-energy radiation carries a significant fraction of the power dissipated at the forward shock. We discuss in detail the expected TeV luminosity, using a robust "minimal" emission model. Then, using the statistical properties of the GRB population (luminosity function, redshift distribution, afterglow energy) we simulate the expected detection rates of GRBs by current and upcoming atmospheric Cherenkov instruments. We find that GRBs exploding into a low-density interstellar medium must produce TeV emission that would have already been detected by the currently operating Cherenkov telescopes. The absence of detections is consistent with explosions into a dense wind of the GRB progenitor. If the typical environment of long GRBs is a Wolf-Rayet progenitor wind, as suggested by the recent analysis of Fermi LAT data, then the upcoming Cherenkov Telescope Array (CTA) should be able to detect a fraction of GRBs that trigger the space-borne detectors. Since absorption by the extragalactic background light limits the detectability above 0.1 TeV for all but the most nearby bursts ($z\lesssim 1$), the reduced energy threshold of CTA is the key improvement over current instruments, which should boost the detection rate by at least a factor of 3.

description: Hot Jupiters are giant Jupiter-like exoplanets that orbit 100x closer to their host stars than Jupiter does to the Sun. These planets presumably form in the outer part of the primordial disc from which both the central star and surrounding planets are born, then migrate inwards and yet avoid falling into their host star. It is however unclear whether this occurs early in the lives of hot Jupiters, when still embedded within protoplanetary discs, or later, once multiple planets are formed and interact. Although numerous hot Jupiters were detected around mature Sun-like stars, their existence has not yet been firmly demonstrated for young stars, whose magnetic activity is so intense that it overshadows the radial velocity signal that close-in giant planets can induce. Here we show that hot Jupiters around young stars can be revealed from extended sets of high-resolution spectra. Once filtered-out from the activity, radial velocities of V830 Tau derived from new data collected in late 2015 exhibit a sine wave of period 4.93 d and semi-amplitude 75 m/ s, detected with a false alarm probability <0.03%. We find that this signal is fully unrelated to the 2.741-d rotation period of V830 Tau and we attribute it to the presence of a 0.77 Jupiter mass planet orbiting at a distance of 0.057 au from the host star. Our result demonstrates that hot Jupiters can migrate inwards in <2 Myr, most likely as a result of planet-disc interactions, and thus yields strong support to the theory of giant planet migration in gaseous protoplanetary discs.

description: Controlling pest insects is a challenge of main importance to preserve crop production. In the context of Integrated Pest Management (IPM) programs, we develop a generic model to study the impact of mating disruption control using an artificial female pheromone to confuse males and adversely affect their mating opportunities. Consequently the reproduction rate is diminished leading to a decline in the population size. For more efficient control, trapping is used to capture the males attracted to the artificial pheromone. The model, derived from biological and ecological assumptions, is governed by a system of ODEs. A theoretical analysis of the model without control is first carried out to establish the properties of the endemic equilibrium. Then, control is added and the theoretical analysis of the model enables to identify threshold values of pheromone which are practically interesting for field applications. In particular, we show that there is a threshold above which the global asymptotic stability of the trivial equilibrium is ensured, i.e. the population goes to extinction. Finally we illustrate the theoretical results via numerical experiments.

description: An integrated photonic platform with anchored-membrane structures, the T-Guide, is proposed and numerically investigated. These compact air-clad structures have high index contrast and are much more stable than prior membrane-type structures. Their semi-infinite geometry enables single-mode and single-polarization (SMSP) operation over unprecedented bandwidths. Modal simulations quantify this behavior, showing that an SMSP window of 2.75 octaves (1.2 - 8.1 μm) is feasible for silicon T-Guides, spanning almost the entire transparency range of silicon. Dispersion engineering for T-Guides yields broad regions of anomalous group velocity dispersion, rendering them a promising platform for nonlinear applications, such as wideband frequency conversion.
Effect of Ionized Impurity Screening on Spin Decoherence at Low and Intermediate Temperatures in GaAs

description: We study the effect of charged impurity screening on spin decoherence in bulk {\it n}-type GaAs, and analyse in details the effect of the use of different Born approximations applied to a linearized Thomas-Fermi screening theory. The spin relaxation times are calculated by ensemble Monte Carlo techniques, including electron-electron, electron-impurities, and electron-phonons scattering. We carefully choose a parameter region so that all the physical approximations hold, and, in particular, a Yukawa-type potential can be used to describe the screened Coulomb interaction and the Born series converges. Our results show that including the second order Born approximation yields much shorter spin relaxation times compared to the commonly implemented first Born approximation: spin relaxation times may be reduced by hundreds of picoseconds, with the first Born approximation overestimating results by 30% or more for a large region of parameters. Though our ensemble Monte Carlo simulations include electron-electron and electron-phonon interactions, when considering low to intermediate carrier densities and $T > 50 $ $\mathrm{K}$, but $T$ smaller than the Fermi temperature, our results are in good agreement with Dyakonov-Perel theory when this includes electron-impurity interactions only, which supports this to be the most relevant scattering mechanism for bulk GaAs in this low-intermediate temperature regime.
Targeting versus Categorical Approaches in Social Safety Nets: The Case of Saudi Arabia's Regular Assistance Program Reform

description: This paper examines the reform of Saudi Arabia's flagship social safety net: the Regular Assistance (RA) Program. The program transitioned from a categorical-based design to a means-based design. The paper first identifies the pre-reform issues associated with the program using survey data from 2017 and 2019, including weak coverage, high exclusion and inclusion errors, low activation rates, and lack of eligibility verification mechanisms. The program's design caused regressive outcomes, with leakage of benefits to higher-income quintiles, which reduced the effectiveness and efficiency of the program. The reform, which was implemented in 2020, aimed to address these challenges and improve the program's effectiveness and efficiency. The reform introduced household means testing, a guaranteed minimum income, mark-ups for dependents and special needs categories, earnings disregards, and links to labor market programs. The paper analyzes the post-reform RA program using administrative data collected in August 2023, focusing on changes in beneficiary characteristics and targeting accuracy. The data suggests that the shift to a means-based approach may have reduced exclusion errors and improved the program's targeting accuracy. The benefits were better directed towards the intended vulnerable groups, leading to a reduction in leakage and an increase in adequacy for those most in need. The paper situates findings within the broader theoretical discourse concerning targeting mechanisms in social safety nets. Understanding the nuances of targeting methods is crucial for designing efficient and inclusive social transfer programs to alleviate poverty and promote socio-economic development.
Communicating with Intention: Family-Centered Care in Early Intervention Through the Interpersonal Lens

description: Effective therapist-parent communication is critical for implementing family-centered practices from a relationship- and capacity-building perspectives. This dissertation aimed to examine the interpersonal aspects of family-centered care using the Intentional Relationship Model (IRM). Two studies were conducted to achieve this aim. The purpose of Study I was to explore therapists’ and parents’ perspectives on 1) parents’ participation, 2) therapists’ use of family-centered practices, and 3) therapists’ communication. Data were collected using online surveys. A total of 101 therapists and 19 parents completed the study. Parents were somewhat involved in the EI sessions. Family-centered behaviors most frequently included relationship-building and least frequently included information sharing. Therapists demonstrated a high frequency of therapeutic communication and low frequency of sub-optimal interaction. Therapists most frequently used empathizing and encouraging modes of communication, followed by instructing, collaborating, problem-solving, and advocating. Parent participation was associated with therapists’ training in family-centered care, training in therapeutic communication, and frequency of family-centered practices. Family-centered practices were significantly associated with therapeutic communication and sub-optimal interaction. The purpose of Study II was to pilot the feasibility, acceptability, and preliminary effectiveness of an IRM-based curriculum for therapists and parents in EI. A total of 27 therapists and six parents completed Study II. Data was collected and analyzed using quantitative and qualitative approaches. Participants appreciated opportunities for social, experiential, and reflective learning and found the IRM applicable to their everyday experiences. Upon course completion, therapists and parents demonstrated increased knowledge, awareness, and reflexivity specific to the interpersonal components of the therapist-parent-child relationship. When describing challenging interpersonal events, participants often felt “stuck” in instructing or empathizing. Upon follow-up, therapists and parents reported increased capacity to cope with stressful interpersonal events through purposeful pausing, as well as increased intentionality and flexibility in their communication. Additionally, therapists demonstrated increased EI self-efficacy, frequency of family-centered practices, and therapeutic mode use. These findings offer evidence supporting 1) a growing need to integrate additional opportunities for translating family-centered theory into clinical practice, and 2) the effectiveness of an IRM-based curriculum for promoting therapists’ and parents’ interpersonal competence in EI.

description: We propose a scheme of loss-resilient entanglement swapping between two distant parties via an imperfect optical channel. In this scheme, two copies of hybrid entangled states are prepared and the continuous-variable parts propagate through lossy media. In order to perform successful entanglement swapping, several different measurement schemes are considered for the continuousvariable parts such as single-photon detection for ideal cases and a homodyne detection for practical cases. We find that the entanglement swapping using hybrid states with small amplitudes offers larger entanglement than the discrete-variable entanglement swapping in the presence of large losses. Remarkably, this hybrid scheme still offers excellent robustness of entanglement to the detection inefficiency. Thus, the proposed scheme could be used for the practical quantum key distribution in hybrid optical states under photon losses.

description: A search for Pauli-exclusion-principle-violating K-alpha electron transitions was performed using 89.5 kg-d of data collected with a p-type point contact high-purity germanium detector operated at the Kimballton Underground Research Facility. A lower limit on the transition lifetime of 5.8x10^30 seconds at 90% C.L. was set by looking for a peak at 10.6 keV resulting from the x-ray and Auger electrons present following the transition. A similar analysis was done to look for the decay of atomic K-shell electrons into neutrinos, resulting in a lower limit of 6.8x10^30 seconds at 90 C.L. It is estimated that the MAJORANA DEMONSTRATOR, a 44 kg array of p-type point contact detectors that will search for the neutrinoless double-beta decay of 76-Ge, could improve upon these exclusion limits by an order of magnitude after three years of operation.

description: The way that individuals use words may convey information about their own social cognitive abilities—how people think of themselves, others, and their environment. Lexical analysis, or looking for patterns of word usage in transcribed text, is a fast and easy method for examining speech and the way in which people use particular words during speech has been shown to be associated with psychological functioning. However, few studies to date have used this method to understand social cognitive processes in individuals with varying levels of schizotypy. In this study, we examined how using words pertaining to social and emotional processes while providing a verbal autobiography, as well as performance on objective social cognitive tasks, are associated with schizotypy. More specifically, we used word use as a model for implicit, more spontaneous social cognition, and performance on an objective social cognitive task as a model for more explicit, deliberate processes, to examine social cognition from a dual-process theory framework. One hundred and one undergraduates enrolled in an introductory psychology course completed an autobiography task as well as a widely used performance-based test of social cognition. Results indicate that as a whole, neither linguistic variables nor objective social cognition task performance significantly predict schizotypy. However, greater use of negative emotional words is significantly associated with higher levels of schizotypy. This could suggest that individuals with schizotypy do not display deficits in implicit or explicit processes of social cognition. However, taken as a whole, these findings may indicate that objective measures of social cognition may not be sufficient to understanding these processes in schizotypy. Future research should employ additional subjective and self-report measures as well as more advanced automated text analysis tools to better understand social cognitive processes in this population.

description: In this paper we prove that, given an open Riemann surface $M$ and an integer $n\ge 3$, the set of complete conformal minimal immersions $M\to\mathbb{R}^n$ with $\overline{X(M)}=\mathbb{R}^n$ forms a dense subset in the space of all conformal minimal immersions $M\to\mathbb{R}^n$ endowed with the compact-open topology. Moreover, we show that every domain in $\mathbb{R}^n$ contains complete minimal surfaces which are dense on it and have arbitrary orientable topology (possibly infinite); we also provide such surfaces whose complex structure is any given bordered Riemann surface. Our method of proof can be adapted to give analogous results for non-orientable minimal surfaces in $\mathbb{R}^n$ $(n\ge 3)$, complex curves in $\mathbb{C}^n$ $(n\ge 2)$, holomorphic null curves in $\mathbb{C}^n$ $(n\ge 3)$, and holomorphic Legendrian curves in $\mathbb{C}^{2n+1}$ $(n\in\mathbb{N})$.

Executive Dysfunction as Risk for Depression

description: Major Depressive Disorder (MDD) is a common and costly illness, with only moderately efficacious treatments available. Identifying risk and potential pathways for the development of MDD can help better inform treatment and prevention efforts. One common deficit in MDD is executive dysfunction; however, few studies have examined whether deficits in executive function (EF) connote risk for MDD. The present study aimed to examine whether 1) EF is poorer among individuals with current MDD and individuals with remitted MDD, compared to depression-free controls, 2) indices of EF are positively correlated within sibling pairs, and 3) family history of MDD is associated with worse performance on EF. In a sample of 402 individuals, we assessed current and lifetime MDD, family history of MDD, and measured two components of EF: set shifting and inhibition, using four subtests from a standardized battery of EF (Delis-Kaplan Executive Function System; DKEFS). Results demonstrated that set shifting deficits were present in both the acute stage of depression as well as in remission from the disease. Set shifting abilities were also significantly associated within sibling pairs, suggesting that these abilities are familial in nature. However, family history of MDD was not associated with worse performance on set shifting or inhibition. This finding may be contributable to incomplete family psychiatric data and potential false negatives in families without a history of MDD. Additionally, inhibition deficits were not present in current MDD, potentially suggesting specificity in the EF deficits in MDD. Taken together, these results lend some support to our hypothesis that set shifting may be a potential vulnerability marker for depression.

description: Measurements of the London penetration depth and tunneling conductance in single crystals of the recently discovered stoicheometric, iron - based superconductor, CaKFe$_4$As$_4$ (CaK1144) show nodeless, two effective gap superconductivity with a larger gap of about 6-9 meV and a smaller gap of about 1-4 meV. Having a critical temperature, $T_{c,onset}\approx$35.8 K, this material behaves similar to slightly overdoped Ba$_{1-x}$K$_x$)Fe$_2$As$_2$ (e.g. $x=$0.54, $T_c \approx$ 34 K)---a known multigap $s_{\pm}$ superconductor. We conclude that the superconducting behavior of stoichiometric CaK1144 demonstrates that two-gap $s_{\pm}$ superconductivity is an essential property of high temperature superconductivity in iron - based superconductors, independent of the degree of substitutional disorder.
“Re-conceptualising student resilience through the liminal space of university, from a non-traditional Applied Health and Social Care graduate perspective”

description: This thesis explores the unique recollections of non-traditional Applied Health and Social Care (n-tAHSC) graduates’ experiences as n-tAHSC students in the liminal space of university. The literature reveals that non-traditional (n-t) students face multiple challenges in UK Higher Education (HE), such as limited knowledge of HE, balancing paid work and study and other responsibilities. These stressors are increased when n-t students study AHSC programmes owing to the interdisciplinary hazards, which include ambiguity around career trajectory, lack of discipline-specific codes of conduct and lack of preparation for stressful people facing roles. Yet these students still achieve successful outcomes. A potential facilitating cause of this success is resilience, identified as both a buffer against the stressors that instigate poor mental health and a catalyst for positive mental health and success in HE. To this end, this thesis conceptualises the articulations and practices (conditions, causes and contingencies) of resilience from the unique perspectives of successful non-traditional Applied Health and Social Care (Sn-tAHSC) graduates, a population that has been under-researched across n-t student resilience literature until now. Using a constructivist approach a sample of 20 successful Sn-tAHSC graduates were interviewed via online video call using Microsoft Teams. Using both a Grounded Theory approach and a Bourdieusian lens to interpret and analyse new understandings from the opinions and views of successful Sn-tAHSC graduates, across domains of agency, habitus, field and capital. The outcomes of the study show that n-tAHSC students articulate resilience differently than their ‘traditional’ student counterparts. Building on a concept of bouncing forward the n-tAHSC student commences university with a repertoire of conditions and strategies for resilience, learned from overcoming previous unique challenges and adversities in their former habitus. These students believe resilience to be further bolstered in the liminal space of university (field) through growth mindsets, problem-focussed coping and social models of resilience where they develop self-efficacy, through sharing and exchanging capital for resilience through formal and informal social interactions with peers, staff and services. This thesis makes an original contribution to the evidence by reconceptualising resilience and creating a unique toolkit for n-tAHSC student resilience. Revealing distinct facilitating conditions, causes and contingencies for resilience where unique ‘bouncing forward’ resilience strategies enable n-tAHSC students to not only survive the challenges of HE, but flourish into successful AHSC graduates.
Approximating the Chromatic Polynomial

description: Chromatic polynomials are important objects in graph theory and statistical physics, but as a result of computational difficulties, their study is limited to graphs that are small, highly structured, or very sparse. We have devised and implemented two algorithms that approximate the coefficients of the chromatic polynomial $P(G,x)$, where $P(G,k)$ is the number of proper $k$-colorings of a graph $G$ for $k\in\mathbb{N}$. Our algorithm is based on a method of Knuth that estimates the order of a search tree. We compare our results to the true chromatic polynomial in several known cases, and compare our error with previous approximation algorithms.
Time-Series Processing and Classication for the Automatic Assessment of Wild Animals Activities

description: Ethology is the science that aims to understand how and why a certain behavior occurs. In order to be able to answer these questions, experts must observe the species of interest for a long time in order to have a sufficiently large database to represent its typical behavior. Once these data have been collected, it is possible to move on to the next phase, the purpose of which is to be able to infer the causes and dynamics that bind different behaviors. If in the second phase the expert's knowledge and skills appear fundamental, in the first phase the human presence causes several problems. For this reason, the proposed work aims to provide a tool to support the expert during the phase of annotation of the activities of the species considered. In detail, it is a methodology to produce machine-learning frameworks capable of recognizing the behavior assumed by the animal, analyzing the time-series measured by sensors such as tri-axial accelerometer and GPS. The absolute novelty that characterizes the proposed methodology is the fact of being focused on the pre-processing phases, in particular, composed of filtering and inconsistencies detection and features extraction, where the role of the data-analyst is central. The classifier is left only with the task of drawing the final conclusion. This methodology has been applied in a real case study, demonstrating the gain in accuracy that a data-driven approach can bring compared to the works already present in the state of the art.
