KEKERASAN SEKSUAL TERHADAP PEREMPUAN DALAM KAJIAN FILSAFAT ISLAM (Studi Pemikiran Feminis-Muslim)
Authors: Kilwouw Astuti Nurlaila
Published: June 2020

Kekerasan seksual merupakan fenomena yang paling banyak menyerang perempuan. Dalam beberapa kasus, pelaku pemerkosaan bahkan tidak segan membunuh korban. Sejauh ini, proses peradilan yang mengadili pelaku tidak kemudian mengurangi jumlah tindak kejahatan. Hal ini disebabkan oleh penyelesaian kasus yang hanya menuntut pertanggungjawaban pidana terhadap pelaku. Sementara itu, terus mengabaikan fakta bahwa kekerasan seksual adalah bentuk kejahatan struktural yang melibatkan pandangan politis terhadap tubuh dan seksualitas, yang diwariskan secara kultural hingga saat ini.  Paradigma masyarakat dalam budaya patriarki menganggap hasrat seksual sebagai kejahatan, sesuatu yang tabu, tidak layak diperbincangkan, dan harus dikekang oleh berbagai norma. Demikian juga dengan pandangan bahwa tubuh perempuan adalah media atau alat untuk memuaskan berahi laki-laki, maka pengungkungan terhadap tubuh perempuan untuk menghindari kemerosotan nilai dianggap sebagai sebuah keharusan. Pada umumnya, justifikasi terhadap paradigma ini dengan menggunakan dalil-dalil yang bersumber dari agama, Islam salah satunya, yang bersandar pada tafsiran atas al-Qur’an dan Hadist. Tulisan ini hendak mengurai bagaimana perspektif para feminis-Muslim dalam melihat fenomena kekerasan seksual dan praktik marginalisasi terhadap perempuan dengan menggunakan sudut pandang Islam. Karena inilah bentuk tanggungjawab politis dan akademis terhadap kehidupan yang lebih aman bagi semua makhluk.

Published: June 2020

Contract Bridge is an intelligent game, which enhances the creativity with multiple skills and quest to acquire the intricacies of the game, because no player knows exactly what moves other players are capable of during their turn. The Bridge being a game of imperfect information is to be equally well defined, since the outcome at any intermediate stage is purely based on the decision made on the immediate preceding stage. One among the architectures of Artificial Neural Networks (ANN) is applied by training on sample deals and used to estimate the number of tricks to be taken by one pair of bridge players is the key idea behind Double Dummy Bridge Problem (DDBP) implemented with the neural network paradigm. This study mainly focuses on Cascade-Correlation Neural Network (CCNN) and Elman Neural Network (ENN) which is used to solve the Bridge problem by using Resilient Back-Propagation (R-prop) Algorithm and Work Point Count System.

Now a days, meeting doctors is quite too frequent. People always meet doctors in order to get treatment for their symptoms. Existing clinic registration systems have to make an appointment with a doctor only when they visit the clinic or hospital and wait in queues for long hours in order to get treatment and everything was tedious too because everything was done manually. So many mistakes could have been made. Therefore, many online appointment systems have been developed in order to book appointments with doctors through mobile application. No priority based appointments and an emergency situation for appointments with doctors is considered. All these aspects are taken into consideration and an online appointment booking system with doctors is especially designed for the Madurai city, Tamil Nadu, India. We will design an android application that tracks the location of a user using particle swarm optimization algorithm and also it displays the details of all the hospitals and clinics in the Madurai district and the available specialists in each stream. This system uses java programming language as interface between the user and doctor and MySQL as the database.

Overview of AD
Authors: Lamb Jacob Joseph
Published: June 2020

There are many methodologies for improving the biogas output from anaerobic digestion. These techniques include physical (e.g., gas production and feedstock parameters), reactor configuration and chemical parameters (e.g., pH and volatile fatty acid concentrations) within the digester can help to link particular functions and features of the process. Using this expanse of data, mathematical models can be used to understand and forecast the biological process within an anaerobic digester. Such models can then be further developed on a process and biological level to improve their ability to mimic the function of the reactor. This chapter will provide background into modelling and reactor configuration in order to obtain a digital twin of an anaerobic digester.

Engineering of anaerobic digestion is an essential step in the design phase of a biogas plant. In order to achieve maximum efficiency and productivity, there are many considerations to be made. The enhancement of the biogas yield from the cycle of anaerobic digestion by analyzing some of the factors that affect the plant’s efficiency in terms of its versatility as a waste management device, as a source of renewable energy and the role it may play in preserving the environment. These considerations are known for process microbiology and biochemistry, process engineering architecture and properties of feedstock. This chapter intends on covering these aspects and giving some foundation behind specific considerations for biogas plant planning.
Analysis and Pre-Treatment of Feedstocks
Authors: Lamb Jacob Joseph
Published: June 2020

Analysis of feedstocks for anaerobic digestion is essential to understand their characteristics. Before feedstocks can be used at an industrial level, their analysis should give information regarding their chemical and physical properties. This allows the operator to assess whether the feedstocks will be ideal for the specific anaerobic digestion process, to establish loading criteria and to avoid failures within the digester. To achieve this, a variety of standardised laboratory experiments have been established that allow consistency of analysis of feedstocks. Additionally, pre-treatment may be required for feedstocks to be utilised to their maximum potential. This is also dependant on the feedstock type and the facilities available for the biogas plant. This chapter gives an overview of the analysis parameters involved with feedstock characterisation, as well as giving the main types of pre-treatment methods currently used in the field.
Digestate and Biogas Cleaning and Processing
Authors: Lamb Jacob Joseph
Published: June 2020

Through anaerobic digestion, raw biogas is produced. This contains significant amounts of energy-containing methane, but the proportion is much lower than natural gas. In order to allow biogas to be used in specific systems, the raw biogas must be cleaned of impurities, and in some cases upgraded to bio-methane (a renewable natural gas equivalent). In addition, the digest produced from anaerobic digestion, although energy-depleted, has high levels of nutrients that can be beneficially used as a fertiliser. In order to use digestate as a fertiliser, a variety of treatments may be required to prevent hazards. In this chapter, the cleaning of the digestate and raw biogas produced in anaerobic digestion are outlined and discussed.
Energy Flow, Process Control and Optimisation
Authors: Lamb Jacob Joseph
Published: June 2020

The desire for economic and environmental efficiency will increasingly lead to the commercial application of specific biogas technology. Investors seek to compare and evaluate technological prospects not only on the basis of investment and operating costs and biogas yields but also on the basis of greenhouse gas emission reduction and renewable energy supply targets. The energy efficiency of a biogas plant must, therefore, be measured and optimized using an energy balance strategy. This chapter gives an overview of the energy flow, process control and optimisation of biogas production.
Upgrading Biogas to Biomethane
Authors: Lamb Jacob Joseph
Published: June 2020

Biogas provides a flexible clean and efficient form of energy. Enriched biogas may generate large volumes of bioCH4, allowing its usage as an alternative to natural gas via existing natural gas networks or being used directly as fuel by vehicles. There are two broad categories of upgrade techniques where traditional methods focus on ex-situ upgrading, treating processed biogas to methane utilizing catalytic (biological and chemical) conversion, membrane gas-permeation, desulphurization, physical and chemical scrubbing, absorption and adsorption. Significant research has been made to increase performance and boost the economic feasibility of the above technologies, and many industrial plants around the world use ex-situ methods to enrich biogas. In-situ techniques such as CO2 desorption, pressurized reactor, H2 addition and electro-methanogenesis have gained considerable attention recently. This chapter discusses and examines state-of-the-art biogas enriching technologies showcasing in-situ and ex-situ methods.
Ficções queer brasileiras: anotações para um dossiê
Authors: Oliveira Geovana Quinalha de , Markendorf Marcio
Published: June 2020

O cânone literário ainda é baseado em um modelo excludente – masculino, branco, heterossexual, classe média – que acaba por instaurar invisibilidades na vida literária, como se comprova a partir da pouca presença de autorias LGBTQI+ em editoras hegemônicas e/ou de personagens LGBTQI+ exercendo função de protagonistas em narrativas. No cenário contemporâneo, no qual as pautas políticas dos estudos de gênero e raça/etnia evidenciaram sua urgência, é necessário sublinhar como tem sido discutida a representação e a representatividade na literatura. Mais do que nunca tem sido demonstrada a potência da identificação entre leitor/a e literatura na construção e fortalecimento das subjetividades individuais, fato que torna preocupante haver poucas obras com as quais pessoas LGBTQI+ possam mirar-se. Contra o cânone excludente não bastariam personagens não hegemônicos em ação, mas seriam necessários projetos literários ou de crítica literária que questionassem os dispositivos e tecnologias normalizadoras do corpo e do gênero. Este texto, nesse sentido, tem por objetivo apresentar minimamente as questões que nortearam a convocatória para um dossiê de ficções brasileiras que teve o queer como chave de leitura política e estética.
Asilo nas Torres: um olhar sobre a ficção científica feminina no Brasil
Authors: Araújo Naiara Sales
Published: June 2020

O presente estudo visa refletir sobre a Ficção Científica de autoria feminina, no Brasil do século XX. Durante muito tempo, este gênero permaneceu marginalizado, sendo considerado pouco representativo dentro da agenda artística nacional. Seu caráter especulativo e futurístico, associado aos avancos técno-científicos parecia não dialogar com o cenário socio-cultural brasileiro, o que limitava sua expressividade. Pesquisas mais recentes vêm lançando olhar mais atento às produções especulativas produzidas a partir do inicio do século XX, sobretudo aquelas produzidas por mulheres e mostrado que este gênero vem sendo fortemente usado como veículo de reflexões e elucubrações no tocante às transformações sociais ocorridas  em decorrência dos avanços tecnológicos. Nesse sentido, tomaremos como objeto de análise a obra Asilo nas Torres (1979), de Ruth Bueno, escrita em um momento histórico conturbado de transformações sociais. Como suporte teórico, traremos à baila os estudos do crítico de Araújo (2018; 2016), Ginway (2010; 2004) e Shaw (2010), dentre outros.
Casais felizes e relações duradouras: a representação da existência lésbica na obra "Amora", de Natalia Polesso
Authors: Vieira Vanessa Ferreira , Figueiredo Eurídice
Published: June 2020

Este artigo tem a proposta de refletir de que maneira a representação de casais lésbicos na literatura contemporânea pode contribuir para desestabilizar o pensamento heterossexual que se sobressai em nossa sociedade. Serão analisados os contos Vó, a senhora é lésbica, Marília acorda e As tias, da obra Amora, de Natalia Polesso (2015). As três narrativas têm como personagens principais casais formados por duas mulheres, as quais vivem juntas há muitos anos e, por isso, podem ser analisadas como exemplo de relacionamento fora do padrão heteronormativo. Servirão de embasamento teórico ao estudo os textos de Monique Wittig (2017), sobre o pensamento straight, de Adrienne Rich (2010), a respeito da existência lésbica, e de Judith Butler (2016), no que tange à questão do feminismo na contemporaneidade. Embora as autoras não concordem em alguns aspectos dessa temática, todas apontam a necessidade de se discutir e se destacar o papel das mulheres lésbicas não apenas no campo literário, mas no mundo acadêmico e social.
Emodin improves the cardiac function in the rats with chronic heart failure through regulation of the miR-26b-5p/PTEN pathway
Authors: Gu Zuncai , Zhang Shuhua , Zhao Siyuan , Cui Ying , Sun Liming
Published: June 2020

Introduction

Chronic heart failure (CHF) is a leading cause of deaths induced by cardiovascular disease. This study aimed to investigate the protective effects of emodin in CHF rats and explore the related mechanisms.

Material and methods

A total of 56 Wistar rats were used to construct CHF model using the coronary artery ligation. The effects of emodin on cardiac function and inflammation were analyzed in the CHF rats. Expression of miR-26b-5p in the CHF model before and after emodin treatment was estimated by quantitative real-time polymerase chain reaction. The effects of miR-26b-5p on cardiac function and inflammation were also assessed, and its target gene was predicted and confirmed in rat cardiomyocyte H9c2.

Results

Emodin treatment could significant improve the cardiac function and inflammation evidenced by the increased increased ejection fraction (EF), fractional shortening (FS), left ventricular systolic pressure (LVSP) and maximum of the first differentiation of left ventricular pressure (+LV dP/dtmax) and decreased atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), left ventricular end diastolic pressure (LVEDP), interleukin (IL)-6, tumor necrosis factor α (TNF-α) levels. Expression of miR-26b-5p was downregulated in the CHF rats (CHF 0.442 ±0.131 vs. Sham 1.044 ±0.160), and this suppressive effect was rescued by emodin (Emodin 0.902 ±0.132 vs. CHF 0.442 ±0.131). The overexpression of miR-26b-5p in CHF rats led to improved cardiac function and inflammatory response. In addition, the emodin-induced increased EF, FS, LVSP and +LV dP/dtmax and decreased ANP, BNP, LVEDP, IL-6 and TNF-α were all abrogated by the knockdown of miR-26b-5p. The target prediction results revealed that PTEN was a target gene of miR-26b-5p in H9c2 cells.

Conclusions

All the results indicated that emodin serves a protective role in CHF via regulation of the miR-26b-5p/PTEN pathway. Emodin may be an effective therapeutic agent for CHF treatment.
Seasonal stratospheric ozone trends over 2000–2018 derived from several merged data sets
Authors: Szeląg Monika E. , Sofieva Viktoria F. , Degenstein Doug , Roth Chris , Davis Sean , Froidevaux Lucien
Published: June 2020

Abstract. In this work, we analyze the seasonal dependence of ozone trends in the stratosphere using four long-term merged data sets, SAGE-CCI-OMPS, SAGE-OSIRIS-OMPS, GOZCARDS, and SWOOSH, which provide more than 30 years of
monthly zonal mean ozone profiles in the stratosphere. We focus here on
trends between 2000 and 2018. All data sets show similar results, although some discrepancies are observed. In the upper stratosphere, the trends are
positive throughout all seasons and the majority of latitudes. The largest
upper-stratospheric ozone trends are observed during local winter (up to 6 % per decade) and equinox (up to 3 % per decade) at mid-latitudes. In
the equatorial region, we find a very strong seasonal dependence of ozone
trends at all altitudes: the trends vary from positive to negative, with the
sign of transition depending on altitude and season. The trends are negative
in the upper-stratospheric winter (−1 % per decade to −2 % per decade) and in the lower-stratospheric spring (−2 % per decade to −4 % per decade), but positive (2 % per decade to 3 % per decade) at 30–35 km in spring, while the opposite pattern is observed in summer. The tropical trends below 25 km are negative and maximize during
summer (up to −2 % per decade) and spring (up to −3 % per decade). In the lower mid-latitude stratosphere, our analysis points to a hemispheric
asymmetry: during local summers and equinoxes, positive trends are observed in the south (+1 % per decade to +2 % per decade), while negative trends are observed in the north (−1 % per decade to −2 % per decade). We compare the seasonal dependence of ozone trends with available analyses
of the seasonal dependence of stratospheric temperature trends. We find that
ozone and temperature trends show positive correlation in the dynamically
controlled lower stratosphere and negative correlation above 30 km, where photochemistry dominates. Seasonal trend analysis gives information beyond that contained in annual
mean trends, which can be helpful in order to better understand the role of
dynamical variability in short-term trends and future ozone recovery
predictions.

Published: June 2020

Abstract. Aerosol intercomparisons are inherently complex, as they convolve instrument-dependent detection efficiencies vs. size (which often change with pressure, temperature, or humidity) and variations on the sampled aerosol population, in addition to differences in chemical detection principles (e.g., including inorganic-only nitrate vs. inorganic plus organic nitrate for two instruments). The NASA Atmospheric Tomography Mission (ATom) spanned four separate aircraft deployments, which sampled the remote marine troposphere from 86° S to 82° N over different seasons with a wide range of aerosol concentrations and compositions. Aerosols were quantified with a set of carefully characterized and calibrated instruments, some based on particle sizing and some on composition measurements. This study aims to provide a critical evaluation of the size-related factors impacting aerosol intercomparisons, and of aerosol quantification during ATom, with a focus on the Aerosol Mass Spectrometer (AMS). The volume determined from physical sizing instruments is compared in detail with that derived from the chemical measurements of the AMS and the Single Particle Soot Photometer (SP2). Special attention was paid to characterize the upper end of the AMS size-dependent transmission with in-field calibrations, which we show to be critical for accurate comparisons across instruments with inevitably different size cuts. Observed differences between campaigns emphasize the importance of characterizing AMS transmission for each instrument and field study for meaningful interpretation of instrument comparisons. Good agreement was found between the composition-based volume (including AMS-quantified sea salt) and that derived from the size spectrometers. The very clean conditions during most of ATom resulted in substantial statistical noise (i.e., precision error), which we show to be substantially reduced by averaging at several-minute time intervals. The AMS captured, on average, 95 ± 15 % of the standard PM1 volume. These results support the absence of significant unknown biases and the appropriateness of the accuracy estimates for AMS total mass/volume for the mostly aged air masses encountered in ATom. The particle size ranges that contribute chemical composition information to the AMS and complementary composition instruments are investigated, to inform their use in future studies.
Transport-limited fluvial erosion – simple formulation and efficient numerical treatment
Authors: Hergarten Stefan
Published: June 2020

Abstract. Most of the recent studies modeling fluvial erosion in the context of tectonic geomorphology focus on the detachment-limited regime. One reason for this simplification is the direct relationship of the constitutive law used here – often called stream-power law – to empirical results on longitudinal river profiles. Another, not less important reason lies in the numerical effort that is much higher for transport-limited models than for detachment-limited models. This study proposes a simple formulation of transport-limited erosion that is as close to empirical results on river profiles as the stream-power law is. As a central point, a direct solver for the fully implicit scheme is presented. This solver requires no iteration for the linear version of the model, allows for arbitrarily large time increments, and is almost as efficient as the established implicit solver for transport-limited erosion. The numerical scheme can also be applied to linear models between the two extremes of detachment-limited and transport-limited erosion.

Abstract. Surficial mass wasting events are a hazard worldwide. Seismic and acoustic signals from these often-remote processes, combined with other geophysical observations, can provide key information for monitoring and rapid response efforts and enhance our understanding of event dynamics. Here we present seismoacoustic data and analyses for two very large ice–rock avalanches occurring on the natural laboratory of Iliamna Volcano, Alaska (USA) on 22 May 2016 and 21 June 2019. Iliamna is a glacier-mantled stratovolcano located in the Cook Inlet, ~ 200 km from Anchorage, Alaska. The volcano experiences massive, quasi-annual slope failures due to glacial instabilities and hydrothermal alteration of material near its summit. The May 2016 and June 2019 avalanches were particularly large and generated energetic seismic and infrasound signals which were recorded on numerous stations at ranges from ~ 9 to over 600 km. Both avalanches initiated in the same location near the head of Iliamna's east-facing Red Glacier, and their ~ 8 km long runout shapes are nearly identical. This repeatability – which is rare for mass movements – provides an excellent opportunity for comparison and validation of seismoacoustic source characteristics. For both events, we invert long-period (15–80 s) seismic signals to obtain a force-time representation of the source. We model the avalanche as a sliding block which exerts a spatially-static point force on the Earth. We use this force-time function to derive constraints on avalanche acceleration, velocity, and directionality which are compatible with satellite imagery and observed terrain features. Our inversion results suggest that the avalanches reached speeds exceeding 80 m s−1, consistent with numerical modeling from previous Iliamna studies. We lack sufficient local infrasound data to test an acoustic source model for these processes. However, the acoustic data suggest that infrasound from these avalanches is produced after the mass movement regime transitions from cohesive block-type failure to granular and turbulent flow – little to no infrasound is generated by the initial failure. At Iliamna, synthesis of advanced numerical flow models and more detailed groundtruth combined with increased geophysical station coverage could yield significant gains in our understanding of these events.
Estimation of rainfall erosivity based on WRF-derived raindrop size distributions

Abstract. Soil erosion can cause various ecological problems, such as land degradation, soil fertility loss, and river siltation. Rainfall is the primary water-driving force for soil erosion and its potential effect on soil erosion is reflected by rainfall erosivity that relates to the raindrop kinetic energy (KE). As it is difficult to observe large-scale dynamic characteristics of raindrops, all the current rainfall erosivity models use the function based on rainfall amount to represent the raindrops KE. With the development of global atmospheric re-analysis data, numerical weather prediction (NWP) techniques become a promising way to estimate rainfall KE directly at regional and global scales with high spatial and temporal resolutions. This study proposed a novel method for large-scale and long-term rainfall erosivity investigations based on the Weather Research and Forecasting (WRF) model, avoiding errors caused by inappropriate rainfall–energy relationships and large-scale interpolation. We adopted three microphysical parameterizations schemes (Morrison, WDM6, and Thompson aerosol-aware [TAA]) to obtain raindrop size distributions, rainfall KE and rainfall erosivity, with validation by two disdrometers and 304 rain gauges around the United Kingdom. Among the three WRF schemes, TAA had the best performance compared with the disdrometers at a monthly scale. The results revealed that high rainfall erosivity occurred in the west coast area at the whole country scale during 2013–2017. The proposed methodology makes a significant contribution to improving large-scale soil erosion estimation and for better understanding microphysical rainfall–soil interactions to support the rational formulation of soil and water conservation planning.
Technical Note: A data-driven method for estimating the
composition of end-members from streamwater chemistry
observations
Authors: Xu Fei Esther , Harman Ciaran Joseph
Published: June 2020

Abstract. End-Member Mixing Analysis (EMMA) is a method of interpreting streamwater chemistry variations, and is widely used for chemical hydrograph separation. It is based on the assumption that the streamwater is a mixture of varying contributions from relatively time-invariant source solutions (end-members). These end-members are typically identified by collecting additional measurements of candidate end-members from within the watershed, and comparing these to the observations. This technical note introduces a complementary, data-driven method: Convex-Hull End-Member Mixing Analysis (CHEMMA), to infer the end-member compositions and their associated uncertainties from the streamwater observations alone. The method involves two steps. The first step uses Convex-Hull Non-negative Matrix Factorization (CH-NMF) to infer possible end-member compositions by searching for a simplex that optimally encloses the streamwater observations. The second step uses Constrained K-means Clustering (COP-KMEANS) to classify the results from repeated applications of CH-NMF to analyze the uncertainty associated with the algorithm. In an example application using the 1986 to 1988 Panola Mountain Research Watershed dataset, CHEMMA is able to robustly reproduce the three field-measured end-members found in previous research using only the streawater chemical observations. It also suggests the existence of a fourth end-member. Further work is needed to explore the constraints and capabilities of this approach.
Triple oxygen isotope systematics of evaporation and mixing processes in a dynamic desert lake system

Published: June 2020

Abstract. Triple oxygen isotope measurements are a novel and promising tool in geochemical and hydrological research. This study investigates the combined hydrogen-deuterium and triple oxygen isotope hydrology at the Salar del Huasco, a highly dynamic salt lake system located on the Altiplano Plateau, N-Chile. The region has a semiarid climate that shows strong seasonal and diurnal variability in relative humidity, temperature, and wind conditions. The Salar del Huasco receives inflow from multiple surface sources and groundwater. Episodic flooding after rare rainfall events imposes seasonal fluctuations of the groundwater table and, thus, the lake level. Applying the Craig and Gordon (C-G) evaporation model for triple oxygen isotope data measured along series of increasingly evaporated lakes and ponds within the salar demonstrates the capability to resolve the individual fundamental hydrologic processes of recharge evaporation, simple (pan) evaporation, and transient mixing with surface and subsurface floodwater. Regarding the stream and spring sources, mixing of different generations of recharge is clearly distinguishable from pre-evaporation of a single recharge event. These processes are not resolvable by δ2H and δ18O measurements alone. We also show that accurate monitoring of the isotopic composition of ambient water vapour and an estimate of the wind turbulence coefficient in the C-G model are critical aspects required to quantify the hydrologic balance. The wind turbulence coefficient, here 0.54, may be determined accurately from on-site evaporation experiments by fitting evaporation trajectories to the d-excess, δ18O and residual fraction data.
Probabilistic tsunami hazard analysis for Tuzla test site using Monte Carlo simulations
Authors: Bayraktar Hafize Basak , Ozer Sozdinler Ceren
Published: June 2020

Abstract. In this study, time-dependent probabilistic tsunami hazard analysis (PTHA) is performed for Tuzla, Istanbul, in the Sea of Marmara, Turkey, using various earthquake scenarios of Prince Island Fault (PIF) within the next 50 and 100 years. The Monte Carlo (MC) simulation technique is used to generate a synthetic earthquake catalogue, which includes earthquakes having moment magnitudes between Mw6.5 and 7.1. This interval defines the minimum and maximum magnitudes for the fault in the case of an entire fault rupture, which depends on the characteristic fault model. Based on this catalogue, probability of occurrence and associated tsunami wave heights are calculated for each event. The study associates the probabilistic approach with tsunami numerical modeling. The tsunami numerical code NAMI DANCE was used for tsunami simulations. According to the results of the analysis, distribution of probability of occurrence corresponding to tsunami hydrodynamic parameters is represented. Maximum positive and negative wave amplitudes show that tsunami wave heights up to 1 m have 65 % probability of exceedance for the next 50 years and this value increases by 85 % in the Tuzla region for the next 100 years. Inundation depth also exceeds 1 m in the region with probabilities of occurrence of 60 % and 80 % for the next 50 and 100 years, respectively. Moreover, probabilistic inundation maps are generated to investigate inundated zones and the amount of water penetrated inland. Probability of exceedance of 0.3 m wave height ranges between 10 % and 75 % according to these probabilistic inundation maps, and the maximum inundation distance calculated in the entire earthquake catalogue is 60 m in this test site. Furthermore, synthetic gauge points are selected along the western coast of Istanbul by including Tuzla coasts. Tuzla is one of the areas that shows high probability exceedance of 0.3 m wave height, which is around 90 %, for the next 50 years while this probability reaches up to more than 95 % for the next 100 years.

Abstract. Due to the complex geological structure of landslides, the installation of a monitoring network could be useful for a variety of scopes studying the possible evolution of a landslide for early warning, and the occurrence of disasters of different types landslides is different not only in the form of deformation, but also in the trigger factor. In the process of landslide monitoring, due to equipment failure and external factors, data loss or abnormal are inevitable. In this paper, through the processing and analysis of the monitoring data of the Zhutoushan landslide, the landslide is rotational landslide which is caused by the rainfall. The box plot is used to detect outliers, and the polynomial fitting function and the moving average denoise method are compared to repair the data, and the latter is better. Through the exploratory analysis of GNSS data, the correlation between monitoring points at different locations is found, which provides a basis for the identification of landslide types.
