Detection of malicious activities against advanced metering infrastructure in smart grid
Creators: name: Jokar, Paria
Publisher: name: University of British Columbia
Year: 2016

description: In this thesis we investigate security challenges in smart grid and propose several algorithms for detecting malicious activities against AMI. Our work includes two parts. In the first part, we focus on the problem of intrusion detection in ZigBee HANs. We study the requirements and challenges of designing intrusion detection systems for HANs, and suggest application of model based intrusion detection and automatic intrusion prevention techniques. Accordingly we design algorithms for detecting and preventing spoofing attacks as an important attack type against wireless networks. We extend this work to design an intrusion detection and prevention system for ZigBee HANs, HANIDPS, which is able to detect and automatically stop various attack types. Through extensive experiments and analysis we show that the proposed method is able to detect and stop the attacks with high precision, low cost and short delay, which makes it suitable for HANs. Considering that in HANIDPS the prevention operation is performed automatically, costs of false positives are low and limited to some network overhead. Also the delay in stopping the attacks is significantly shortened compared to when human intervention is required. This reduces the damages caused by possible attacks. In the next part, we focus on detection of cyber intrusions that affect the load curve. We suggest that by monitoring abnormalities in customers' consumption pattern these attacks are detectable. We introduce a consumption pattern based electricity theft detector, CPBETD, which unlike previous techniques is robust against nonmalicious changes in consumption pattern and provides a high and adjustable performance without jeopardizing customers' privacy. Extensive experiments on real dataset of 5000 customers show the effectiveness of our approach. We also introduce instantaneous anomaly detector, IAD, which by monitoring the usage patterns effectively detects attacks against direct and indirect load control which are some of the major concerns in AMI.

description: We review recent activity searching for variations in the fundamental constants of nature in quasar absorption spectra and in the laboratory. While research in this direction has been ongoing for many decades, the topic has recently been stimulated by astronomical evidence for spatial variation in the fine-structure constant, alpha. This result could be confirmed using different quasar data and atomic clock measurements, but there are significant challenges to obtain the required accuracy. We review existing measurements and discuss some of the most promising systems where any variations would be strongly enhanced.

description: We consider averages $κ$ of spectral measures of rank one perturbations with respect to a $σ$-finite measure $ν$. It is examined how various degrees of continuity of $ν$ with respect to $α$-dimensional Hausdorff measures ($0 \leq α\leq 1$) are inherited by $κ$. This extends Kotani's trick where $ν$ is simply the Lebesgue measure.

description: This booklet contains hands-on STEM activities related to climate change and energy. It can be used to support professional development workshops for teachers, programming for informal STEM learning settings such as science centres and school outreach programs, activities for students (note some hazardous activities are only suitable for a teacher demonstrations), as a resource for curriculum development, or for remote/distance education. We would appreciate your feedback on the activities, please complete the survey at https://bit.ly/ClimateConnectionsBook (https://anu.au1.qualtrics.com/jfe/form/SV_eRq51SRiZ5r7s7c). Contact Graham at the Australian National University Centre for the Public Awareness of Science (CPAS) on g.walker@anu.edu.au for any questions or comments. With climate change, it’s important to teach/communicate the solutions (positives) along with the problems (negatives), so the booklet is divided into two parts: •What’s happening? The science, causes and impacts of climate change •What we can do – mitigation, adaptation and solutions You can watch selected activities at https://www.youtube.com/watch?v=voRqIwQgK1E&t=2974s and please see our Youtube page for more resources. These activities introduce selected aspects of climate change and energy, but are not intended to be a definitive guide, or to cover all the science behind climate.

description: We measure the anisotropic mid-infrared response of electrons and phonons in bulk YBa2Cu3O7 after femtosecond photoexcitation. A line shape analysis of specific lattice modes reveals their transient occupation and coupling to the superconducting condensate. The apex oxygen vibration is strongly excited within 150 fs demonstrating that the lattice absorbs a major portion of the pump energy before the quasiparticles are thermalized. Our results attest to substantial electron-phonon scattering and introduce a powerful concept probing electron-lattice interactions in a variety of complex materials.

Evaluating how neighbourhood housing diversity relates with residential location choice, residential satisfaction and health
Creators: name: Machler, Leonard
Publisher: name: University of British Columbia
Year: 2016

description: Urban planners have long advocated strategies that enable a broad spectrum of the population to live in their preferred communities. In particular, planning researchers emphasize the importance of enabling households with preferences for Smart Growth communities to match. Living in Smart Growth communities – characterized by higher densities, more mixed land uses, and better access to transport alternatives to the car - has been empirically linked with improved health, environmental and economic outcomes. One widely cited neighbourhood matching strategy is to increase the level of housing mix - or the diversity and distribution of different housing typologies within a neighbourhood - to permit households of lesser financial means to trade living space for an opportunity to live in their desired communities. However, no empirical study has investigated whether increased neighbourhood housing mix is associated with higher levels of neighbourhood matching in the population. The purpose of this dissertation is to evaluate the effectiveness of housing mix as a planning strategy. Using data obtained from a residential preference survey of 1,186 Vancouver area households, this project investigates the association between neighbourhood housing mix and the ability for households to match into their preferred neighbourhood type. The project also tests the association between neighbourhood match and neighbourhood satisfaction as well as the association between neighbourhood match and two measures of health: self-reported health status and body mass index (BMI). Neighbourhood match is defined two ways: based on a survey respondent’s subjective interpretation of their actual neighbourhood design compared to their preferences (i.e. “subjective match), and a comparison of the respondent’s survey-indicated preference versus an objective assessment of their community based on measurable features of the built environment (i.e. “objective match”). Findings reveal that housing mix only significantly predicts objective match, and significant associations are limited to owner-occupiers and respondents under the age of 60. Objective match is not a significant predictor of neighbourhood satisfaction or health. This dissertation concludes that housing mix is not an effective planning strategy for enabling households with Smart Growth preferences to live in their desired community.
Heresias e dissidências: regalismo e anti-regalimo no século XV
Creators: name: Ventura, Margarida Garcês
Publisher: name: Lusitania Sacra
Year: 1998

description: O próprio título aponta para uma interacção entre duas realidades: por um lado, as heresias e dissidências; por outro, o regalismo. Alertado o leitor para a dificuldade de estabelecer, no século XV, as reais fronteiras entre ortodoxia e heresia ou dissidência, chama-se à atenção para o facto de, nos finais do século, heresia ser equiparada a crimes contra o rei. Ultrapassada a questão sobre a pertinência do termo «regalismo» versus «galicanismo», o texto situa-se nas polémicas intervenções régias em matérias ditas «espirituais» ou «eclesiásticas», nomeadamente as crenças e práticas contrárias ou marginais à doutrina da Igreja. A questão fundamental é a da obrigação que ultrapassa a licitude de o poder régio castigar heresias e dissidências, tendo em conta que a intervenção régia poderá ser vista como um instrumento de aplicação do colírio contra as heresias, ou melhor, contra hereges e dissidentes. Tal questão envolve toda a concepção do ofício de rei e das funções da Igreja. O artigo destaca alguma legislação que aponta para o reforço da política intervencionista de D. Afonso V em matérias relacionadas com a fé, nomeadamente o alvará régio de 18 de Agosto de 1451. E conclui relacionando o regalismo vigente em Portugal com a adesão ao princípio do senhorio papal sobre todo o universo.

description: The cosmic censorship hypothesis, introduced by Penrose forty years ago, is one of the corner stones of general relativity. This conjecture asserts that spacetime singularities that arise in gravitational collapse are always hidden inside of black holes. The elimination of a black-hole horizon is ruled out by this principle because that would expose naked singularities to distant observers. We test the consistency of this prediction in a gedanken experiment in which a charged object is swallowed by a charged black hole. We find that the validity of the cosmic censorship conjecture requires the existence of a charge-mass bound of the form $q\leqμ^{2/3}E^{-1/3}_c$, where $q$ and $μ$ are the charge and mass of the physical system respectively, and $E_c$ is the critical electric field for pair-production. Applying this bound to charged atomic nuclei, one finds an upper limit on the number $Z$ of protons in a nucleus of given mass number $A$: $Z\leq Z^*=α^{-1/3}A^{2/3}$, where $α=e^2/\hbar$ is the fine structure constant. We test the validity of this novel bound against the $(Z,A)$-relation of atomic nuclei as deduced from the Weizsäcker semi-empirical mass formula.

Theory of Secular Chaos and Mercury's Orbit

description: We study the chaotic orbital evolution of planetary systems, focusing on secular (i.e., orbit-averaged) interactions, because these often dominate on long timescales. We first focus on the evolution of a test particle that is forced by multiple massive planets. To linear order in eccentricity and inclination, its orbit precesses with constant frequencies. But nonlinearities can shift the frequencies into and out of secular resonance with the planets' eigenfrequencies, or with linear combinations of those frequencies. The overlap of these nonlinear secular resonances drive secular chaos in planetary systems. We quantify the resulting dynamics for the first time by calculating the locations and widths of nonlinear secular resonances. When results from both analytical calculations and numerical integrations are displayed together in a newly developed "map of the mean momenta" (MMM), the agreement is excellent. This map is particularly revealing for non-coplanar planetary systems and demonstrates graphically that chaos emerges from overlapping secular resonances. We then apply this newfound understanding to Mercury. Previous numerical simulations have established that Mercury's orbit is chaotic, and that Mercury might even collide with Venus or the Sun. We show that Mercury's chaos is primarily caused by the overlap between resonances that are combinations of four modes, the Jupiter-dominated eccentricity mode, the Venus-dominated inclination mode and Mercury's free eccentricity and inclination. Numerical integration of the Solar system confirms that a slew of these resonant angles alternately librate and circulate. We are able to calculate the threshold for Mercury to become chaotic: Jupiter and Venus must have eccentricity and inclination of a few percent. Mercury appears to be perched on the threshold for chaos.

description: The $α$-particle condensate in nuclei is a novel state described by a product state of $α$'s, all with their c.o.m. in the lowest 0S orbit. We demonstrate that a typical $α$-particle condensate is the Hoyle state ($E_{x}=7.65$ MeV, $0^+_2$ state in $^{12}$C), which plays a crucial role for the synthesis of $^{12}$C in the universe. The influence of antisymmentrization in the Hoyle state on the bosonic character of the $α$ particle is discussed in detail. It is shown to be weak. The bosonic aspects in the Hoyle state, therefore, are predominant. It is conjectured that $α$-particle condensate states also exist in heavier $nα$ nuclei, like $^{16}$O, $^{20}$Ne, etc. For instance the $0^+_6$ state of $^{16}$O at $E_{x}=15.1$ MeV is identified from a theoretical analysis as being a strong candidate of a $4α$ condensate. The calculated small width (34 keV) of $0^+_6$, consistent with data, lends credit to the existence of heavier Hoyle-analogue states. In non-self-conjugated nuclei such as $^{11}$B and $^{13}$C, we discuss candidates for the product states of clusters, composed of $α$'s, triton's, and neutrons etc. The relationship of $α$-particle condensation in finite nuclei to quartetting in symmetric nuclear matter is investigated with the help of an in-medium modified four-nucleon equation. A nonlinear order parameter equation for quartet condensation is derived and solved for $α$ particle condensation in infinite nuclear matter. The strong qualitative difference with the pairing case is pointed out.

description: Little Higgs theory naturally predicts a light Higgs boson whose most important discovery channel at the LHC is the di-photon signal $pp\to h\to γγ$. In this work we perform a comparative study for this signal in some typical little Higgs models, namely the littlest Higgs model (LH), two littlest Higgs models with T-parity (named LHT-I and LHT-II) and the simplest little Higgs modes (SLH). We find that compared with the Standard Model prediction, the di-photon signal rate is always suppressed and the suppression extent can be quite different for different models. The suppression is mild ($\lsim 10%$) in the LH model but can be quite severe ($\simeq 90%$) in other three models. This means that discovering the light Higgs boson predicted by the little Higgs theory through the di-photon channel at the LHC will be more difficult than discovering the SM Higgs boson.

description: Rituximab is a FDA-approved monoclonal antibody for adults with moderate to severe potentially life-threatening pemphigus vulgaris. Recent studies have focused on assessments of efficacy and safety of low-dose rituximab (<2 gram in each cycle). Databases were searched from 2010 to 2020 (last update: 1 June 2020). Nine studies were entered; including180 cases (92: women, 88: men, age range: 9–83 years). The dosages of each Rituximab cycle varied between ultra-low-dose (≤500 mg for a cycle, either multiple infusions or a single infusion), low-dose (2 × 375 mg/m2 or 2 × 500 mg) and modified-dose (3 × 375 mg/m2 or 3 × 500 mg). The efficacy and safety of Rituximab in the studies are known by the recovery time, relapse time, and side events. According to the studies, 2 × 500 can lead to complete remission in a broad range, from 35 to 82%. These differences might be explained by different end-points and variable cumulative corticosteroid dosage after RTX administration. Although the studies showed that low dose RTX is efficient, there are some controversies regarding the choosing low-dose for severe patients. Considering the effectiveness of low-dose, intermediate dose, and ultra-low-dose protocols of Rituximab in inducing remission in pemphigus disease and considering factors such as cost of therapy, and the need to induce a minimum of immunosuppression for a minimum duration in the COVID-19 pandemic, suggested to use low-dose Rituximab protocol (2 infusions of 500 mg Rituximab: interval of 2 weeks) to induce the remission in mild-to-moderate pemphigus patients.

description: OS LIVROS DE LINHAGENS são compilações genealógicas da nobreza medieval portuguesa, organizadas em torno da memória de algumas grandes casas e seus ramos colaterais. Compostas sobretudo por listas de sucessão familiar e narrativas mais ou menos lendárias, conhecemos hoje três obras que se podem incluir neste género tipicamente aristocrático: os chamados Livro Velho, Livro do Deão e Livro de Linhagens do Conde D. Pedro de Barcelos. Como todos os instrumentos cristalizadores e veiculantes da consciência histórica de um grupo, também estes registos estão ao serviço de uma determinada visão do passado e, portanto, da construção de um presente que procura na tradição a sua legitimidade. Partindo justamente da noção de legitimidade, que nos parece central na ideologia dos nobiliários, pretendemos estudar uma das categorias políticas mais importantes na luta das estirpes portuguesas para definir identidades, estabelecer hierarquias e defender privilégios: a relação com o sagrado. Tal relação pode apresentar-se de duas formas: ou invocando a participação na Reconquista, ao lado de toda a nobreza hispânica, e a fundação ou patrocínio de comunidades monásticas, base sólida de poder simbólico e material; ou exibindo com anjos e santos (por exemplo Santiago e São Pedro) uma especial intimidade, concretamente através de aparições, e a correspondente solicitude divina .

description: Today’s young people are critical stakeholders in the future of care policy and services. As caregivers, care workers and people who will need support in the future, they will inherit the consequences of policy choices made now. However, the experiences and priorities of young people are often overlooked in public debate and deliberations on disability services, aged care, and support for family carers. This report presents the findings of a pilot project involving focus groups with young adults living in the Australian Capital Territory with a variety of lived experiences of providing care and support, as well as those without any direct caring experience. It centres on the voices and perspectives of the young adult participants. The focus groups explored participants’ experiences of caring over the past two years, which included the advent of the COVID-19 virus and associated lockdowns, as well as their views about the formal care and support sector, experiences of disability and carer support services, and hopes for the future.

description: O presente artigo pretende reavaliar o primeiro século de vigência da diocese de Lisboa, a partir da sua restauração após 1147, sob a perspectiva das relações entre a realeza e a Igreja. Estabeleceu-se. assim, um esboço de periodização, no qual se pode distinguir um primeiro momento de «harmonia», onde se podem detectar diversas estratégias de domínio de parte a parte mas durante o qual os conflitos são pouco sensíveis ou facilmente sanados. Um segundo período, iniciado com o episcopado de Soeiro Viegas e prolongando-se pela fase agitada da vacância dos anos 32-39, parece caracterizar-se pela dissensão permanente e reflectir não só os problemas da cidade e deste bispado. mas a situação generalizada de instabilidade e tensão que perpassa os reinados de Afonso II e de seu filho Sancho. Na última parte, referente aos episcopados de João e do seu sucessor, Airas Vasques, analisam-se os conflitos no contexto político em que se inserem. por reflectirem as vicissitudes, virtualidades e jogos políticos que servem e a quem serve um bispo e seu cabido nos conturados anos da deposição do «rex innutilis».

description: We report on photoluminescence measurements of vertically stacked InAs/GaAs quantum dots grown by molecular-beam epitaxy on focused ion beam patterned hole arrays with varying array spacing. Quantum dot emission at 1.24 eV was observed only on patterned regions, demonstrating preferential nucleation of optically-active dots at desired locations and below the critical thickness for dot formation at these growth conditions. Photoluminescence measurements as a function of varying focused ion beam irradiated hole spacing showed that the quantum dot emission intensity increased with decreasing array periodicity, consistent with increasing dot density.

description: We propose an elasto-plastic inspired friction model which incorporates interfacial stiffness. Steady state sliding friction is characterized by a generic nonmonotonic behavior, including both velocity weakening and strengthening branches. In 1D and upon the application of sideway loading, we demonstrate the existence of transient cracklike fronts whose velocity is independent of sound speed, which we propose to be analogous to the recently discovered slow interfacial rupture fronts. Most importantly, the properties of these transient inhomogeneously loaded fronts are determined by steady state front solutions at the {\em minimum} of the sliding friction law, implying the existence of a new velocity scale and a "forbidden gap" of rupture velocities. We highlight the role played by interfacial stiffness and supplement our analysis with 2D scaling arguments.

description: Apesar de ser um dos mais importantes autores do proto-cristianismo, Orósio. Um bracarense, não resistiu a incluir na sua obra mais significativa, a História contra os Pagãos, uma série de material cujo substrato era o da Cultura Clássica. Este texto analisa como Orósio aproveitou esses dados e elementos. Nomeadamente os mitológicos. Fazendo deles uma espécie de interpretatio christiana do pensamento religioso e do sistema cultural que vigorava no Império, e no qual nasceu e se instituiu o Cristianismo.

title: Establishing the rules of the game: Bargaining power in relations between the European Union and the Republic of Azerbaijan
Creators: name: Van Gils, Eske

description: The European Union (EU) has had a range of policy objectives, many of them transformative, in the countries in its eastern neighbourhood since their independence from the Soviet Union in 1991. However, there appear to be limits to the EU's success in fulfilling the objectives with a transformative character, especially in its relations with Azerbaijan. This thesis examines why the EU faces limits to this fulfilment, by examining Azerbaijan's strategic use of bargaining power as a possible explanation for these hindrances. This research is premised on the idea that policy-making in bilateral relations can be seen as a form of continuous negotiation, which outcomes are determined by the EU and Azerbaijan's respective negotiation success based on their strategic application of bargaining power. The hypothesis tested in this thesis is that the lack of inclusive policy-making by the EU has led the Azerbaijani government to use bargaining strategies in order to enforce more inclusive policies, where the initial EU objectives are not in line with Baku's interests. This resistance to the EU's transformative objectives could then explain why the latter are only fulfilled in part. This idea will be tested on three different policy areas: agenda-setting of the Nagorno-Karabakh conflict; democracy and human rights promotion policies; and the negotiations over economic and legal approximation. The case studies will corroborate the hypothesis but demonstrate variations in the successful application of bargaining power strategies to the three policy domains. This research will conclude that the current configuration of power considerably limits the fulfilment of EU transformative objectives in the neighbourhood, and requires substantial change in the EU policies and attitudes, through more inclusive forms of policy-making, to be more effective and sustainable. This study makes three important contributions to the scholarship: it develops the concept of bargaining power in international relations, and links it to the concept of inclusive policy-making to comprehensively ascertain the EU's capacity to meet its transformative objectives. Furthermore, it sheds an empirical light on Azerbaijan as a hitherto understudied country case of international relations.

description: The properties of strange mesons ($K$, $\bar K$ and $\bar K^*$) in dense matter are studied using a unitary approach in coupled channels for meson-baryon scattering. The kaon-nucleon interaction incorporates $s$- and $p$-wave contributions within a chiral model whereas the interaction of $\bar K^*$ with nucleons is obtained in the framework of the local hidden gauge formalism. The in-medium solution for the scattering amplitude accounts for Pauli blocking effects, mean-field binding on baryons, and meson self-energies. We obtain the $K$, $\bar K$ and $\bar K^*$ (off-shell) spectral functions in the nuclear medium and study their behaviour at finite density, temperature and momentum. We also analyze the energy weighted sum rules of the kaon propagator as a quality test of model calculations. We finally estimate the transparency ratio of the $γA \to K^+ K^{*-} A^\prime$ reaction, which we propose as a feasible scenario at present facilities to detect in-medium modifications of the $\bar K^*$ meson.

description: The linearly polarized Gowdy $T^3$ model can be regarded as compact Bianchi I cosmologies with inhomogeneous modes allowed to travel in one direction. We study a hybrid quantization of this model that combines the loop quantization of the Bianchi I background, adopting the improved dynamics scheme put forward by Ashtekar and Wilson-Ewing, with a Fock quantization for the inhomogeneities. The Hamiltonian constraint operator provides a resolution of the cosmological singularity and superselects separable sectors. We analyze the complicated structure of these sectors. In any of them the Hamiltonian constraint provides an evolution equation with respect to the volume of the associated Bianchi I universe, with a well posed initial value problem. This fact allows us to construct the Hilbert space of physical states and to show that we recover the standard quantum field theory for the inhomogeneities.

description: Optical properties of a two-dimensional quantum ring with pseudopotential in the presence of an external magnetic field and magnetic flux have been theoretically investigated. Our results show that both of the pseudopotential and magnetic field can affect the third nonlinear susceptibility and oscillator strength. In addition, we found that the oscillator strength and the absolute value of the resonant peak of the linear, non-linear and total absorption coefficient vary periodically with magnetic flux, while the resonant peak value of the linear, non-linear and total refractive index changes decreases as magnetic flux increases.

Interspecific boreal shrub growth response to climate, fertilization and herbivory.

description: Substantial evidence indicates a circumpolar ‘greening’ trend largely attributed to an increase in tall shrub abundance. Shrub expansion creates positive feedbacks to the global climate, involving the release of stored carbon due to shifts in permafrost stability and nutrient cycling. Understanding drivers of shrub growth is therefore essential to predicting how northern ecosystems will respond to climate change. After a decade of research into circumpolar shrub expansion, there remain large gaps in our understanding of shrub expansion below treeline in the boreal forest biome. In the Kluane region of southwest Yukon, there has been an increase in the aboveground standing biomass of boreal shrubs by one and a half to two times over the past 27 years. I used dendroecological methods to assess the relative impacts of climate, fertilization, and herbivory on three boreal understory shrub species (Betula glandulosa, Salix glauca, and Shepherdia canadensis) and found interspecific variation in growth response. I used a mixed effects model selection analysis to determine which factors were strongest in determining annual ring width. B. glandulosa had increased ring widths with added nutrients, S. glauca was not climate or nutrient sensitive, and S. canadensis responded to precipitation and drought index climate variables. When the same growth analysis was performed on canopy trees in the same area, Picea glauca ring widths were found to be more climate and nutrient sensitive than the shrubs growing beneath them. However, the response of shrub growth to the aforementioned factors was not strongly associated with canopy cover by trees. This indicates there is a difference between trees and shrubs in their growth response other than the influence of canopy species on understory light availability. If shrubs continue to increase, and boreal trees decline in health (drought, insects, fire) as predicted, there could be a shift from a more tree-dominated to a more shrub-dominated system. This would influence local habitat for key wildlife species and global climate feedbacks via carbon storage or release. The boreal forest is one of the largest forests in the world, and understanding vegetation change in this biome is essential for adapting to climate change.

description: By starting from the stochastic Schrödinger equation and quantum trajectory theory, we introduce memory effects by considering stochastic adapted coefficients. As an example of a natural non-Markovian extension of the theory of white noise quantum trajectories we use an Ornstein-Uhlenbeck coloured noise as the output driving process. Under certain conditions a random Hamiltonian evolution is recovered. Moreover, we show that our non-Markovian stochastic Schrödinger equations unravel some master equations with memory kernels.

Contribution of the Gamma-ray Loud Radio Galaxies Core Emissions to the Cosmic MeV and GeV Gamma-Ray Background Radiation

description: The Fermi gamma-ray satellite has recently detected gamma-ray emissions from radio galaxy cores. From these samples, we first examine the correlation between the luminosities at 5 GHz, L_{5GHz}, and at 0.1-10 GeV, L_{gamma}, of these gamma-ray loud radio galaxies. We find that the correlation is significant with L_{gamma} \propto L_{5GHz}^{1.16} based on a partial correlation analysis. Using this correlation and the radio luminosity function (RLF) of radio galaxies, we further explore the contribution of gamma-ray loud radio galaxies to the unresolved extragalactic gamma-ray background (EGRB). The gamma-ray luminosity function is obtained by normalizing the RLF to reproduce the source count distribution of the Fermi gamma-ray loud radio galaxies. We find that gamma-ray loud radio galaxies will explain ~25% of the unresolved Fermi EGRB flux above 100 MeV and will also make a significant contribution to the EGRB in the 1-30 MeV energy band. Since blazars explain 22% of the EGRB above 100 MeV, radio loud active galactic nuclei (AGNs) population explains ~47% of the unresolved EGRB. We further make an interpretation on the origin of the EGRB. The observed EGRB spectrum at 0.2-100 GeV does not show an absorption signature by the extragalactic background light. Thus, the dominant population of the origin of EGRB at very high energy (>30 GeV) might be nearby gamma-ray emitting sources or sources with very hard gamma-ray spectrum.
