Estimation of static jacking load (Pep) for the prestressed centrifugal concrete piles on some types of ground structure in Hai Duong city
Authors:   DAVICO JSC, Hai Duong City, Vietnam  Faculty of Geosciences and Geoengineering, Hanoi University of Mining and Geology, Vietnam
Published: July 2021

Nowadays, the prestressed centrifugal concrete piles (PCCP) are applied in most major construction projects in Hai Duong city. The pile bearing capacity and static jacking load (Pep) are very important parameters for optimizing the pile foundation design, and they depend on the types of ground structure. The paper introduces the estimated method for the pile static jacking load which was applied for two types of ground structure in Hai Duong city (type I and type II). The results showed that the maximum static jacking load (Pepmax) was 66.6 tons and 76.6 tons at the depth of 32 m for types I and II, respectively. The results of evaluation and comparison between the calculated Pep with the actual Pep have provided the penetration coefficient (K) for each soil: K = 1.8 for fine sand; K = 1.5 for stiff sandy clay; K = 1.4 for firm sandy clay and K = 1.2 for soft soil.
Highly photocatalytic activity of natural halloysite - based material for the treatment of dyes in wastewater
Authors:   Faculty of Oil and Gas, Hanoi University of Mining and Geology, Vietnam
Published: July 2021

In this study, the halloysite nanotube material will be fabricated from a natural halloysite mineral and used as a support for the photocatalytic activity phase based on TiO2. The material is characterized by modern physicochemical methods such as XRD, SEM, BET, UV - vis spectrum, and EDX. Accordingly, the refined halloysite has a nanoscale with a length of about 1.3 μm and a capillary size of about 5 nm. After the deposition of Ag - TiO2 on the halloysite, the specific surface of the material measured by the BET method was about 60 m2/g, and the structure of the halloysite was intact. The band - gap energy of as - prepared materials is also significantly improved in comparison to pure TiO2, makes the material capable of absorbing longer wavelengths of light in the photocatalytic process. The Photocatalyst based on Halloysite and TiO2 showed very high efficiency, up to more than 95% in the decomposition of typical organic pollutant RR - 195. This result shows great potential in this novel material in environmental treatment applications.
Geological controls on focused fluid flow in the Song Hong Basin, offshore Vietnam
Authors:   Faculty of Oil and Gas, Hanoi University of Mining and Geology, Vietnam
Published: July 2021

This study uses 2D seismic lines located in the central Song Hong Basin, covering an area of c. 3900 m2, in the water depth of c. 100 m. Focused fluid flows are developed intensively and can be classified into two types: blow - out pipe and seepage pipe. They have similar seismic characteristics as a vertical zone of disturbed seismic reflections. The significant difference between them is the blow - out pipes associated with seafloor pockmarks and paleo - pockmarks which are absent in the seepage pipe. Besides, the scale of the blow - out pipe is larger, compared with the seepage pipe. The blow - out pipe is c. 500 m wide and 450÷3500 ms TWT; the seepage pipe is smaller scale, c. 200 m wide and 500 ms TWT. Blow - out pipe is rooting from the sequence just above the diapir or deformation unit or deep lacustrine mudstones from the Late Eocene to Oligocene, and marine mudstones from the Early to Middle Miocene. The seepage pipe is rooting from the sequence above the diapir. The focused fluid flow is supposed to be controlled by the overpressured deep source layers and passive diapirism. The occurrence of focused fluid flow is an indicator for the active petroleum system in the study area. Intensive development of focused fluid flow proves a great hydrocarbon potential in the Song Hong basin.
Estimation of shale volume from well logging data using Artificial Neural Network
Authors:   Faculty of Oil and Gas, Hanoi University of Mining and Geology, Vietnam
Published: July 2021

The existence of shale has a major effect on reservoir quality because it reduces the rock’s both the porosity and permeability. There are several types of shale, and they can be distributed in the sand in four different ways: laminated, structural, dispersed, or any combination of these. Each of them has various features and physical properties. Therefore, shale volume estimation is one of the most important and challengin tasks to be solved information evaluation. There are many equations proposed to calculate shale volume from Gamma - ray log; however, none of them could be considered the best method that can be applied to all case studies. This study aims to propose a new approach to estimate shale volume from well - logging data. Gamma - ray and other logs were used as input data for an artificial neural network (ANN) to predict the shale volume. We apply this technique to the 1143 data set of the ocean drilling program (ODP) in the East Sea. The authors compared the result to core data and recognized that utilization of several logs and ANN gives a better estimation than conventional methods (more accurate and can reflect the trend of actual shale volume).
Sinergi Pelayan dan Jemaat Tuhan Menurut 1 Korintus 3:4-9
Authors: Halawa Desti Ratna Sari
Published: July 2021

AbstractThis paper examines the meaning of synergy in the ministry and life of believers according to 1 Corinthians 3: 4-9. Servants of God tend to leave the place of service because they are at odds with God or others. Among the Corinthians in the early church, there was strife among the members of the body of Christ. To deal with divisions, Paul talks about becoming partners with God (synergy). In the Orthodox  church this concept emphasizes how to achieve salvation but this concept is not emphasized in the world of ministry. Whereas in Protestant literature this concept is rarely even perhaps foreign to be discussed as something important, so that it is reflected in ministries within the church and outside the church which often cause divisions. The results show that only through synergy with God can humans synergize with one another (one with God and one with others remains strong). Synergize is to be partners with Allah who continue to exercise their free will according to God's will so that they are not easily tempted by the evil of sin. Remembering God dynamically produces union with God and gives the best service to others as Christ served. Of course, only synergy makes humans avoid fellowship and enmity between others. AbstrakTulisan ini meneliti makna sinergi dalam pelayanan dan kehidupan orang percaya menurut 1 Korintus 3:4-9. Pelayan Tuhan cenderung meninggalkan tempat pelayanan karena berselisih dengan Allah atau sesama. Di antara jemaat Korintus di masa gereja mula-mula perselisihan di antara anggota tubuh Kristus sudah terjadi. Untuk menghadapi perpecahan, Paulus berbicara bagaimana menjadi kawan sekerja Allah (sinergi). Dalam gereja Ortodoks konsep ini menekankan bagaimana mencapai keselamatan akan tetapi konsep ini tidak ditekankan dalam dunia pelayanan. Sedangkan dalam literatur Protestan konsep ini jarang bahkan mungkin asing dibahas sebagai sesuatu yang penting, sehingga tercermin dalam pelayanan-pelayanan dalam gereja maupun di luar gereja yang sering menimbulkan perpecahan. Hasil penelitian menunjukkan bahwa hanya melalui sinergi dengan Allah manusia bisa bersinergi dengan sesamanya (menyatu dengan Allah dan persatuan dengan sesama tetap kokoh). Bersinergi adalah menjadi kawan sekerja Allah yang terus melatih kehendak bebasnya sesuai dengan kehendak Allah sehingga tidak mudah tergoda oleh kejahatan dosa. Mengingat Allah secara dinamis menghasilkan persatuan dengan Allah dan memberi pelayanan terbaik kepada sesama seperti Kristus melayani. Tentunya, hanya sinergilah yang membuat manusia terhindar dari persekutuan serta permusuhan di antara sesama.

Authors: Octavianie Adhitya , Adi Putra Aqram
Published: July 2021

Voice Communication Control System (VCCS) is a tool designed to make it easier for users to communicate voice by integrating all users (clients) and means of communication in one system and controlled using a control panel. VCCS is a voice switching device used in VHF A / G and Direct Speech communications. The benefit of using VCCS is that when the user makes flight communication it becomes easy because all frequencies and telephones are combined in a VCU (Voice Control Unit) so that the ATC desk/work desk is not filled with communication devices. In addition, to facilitate its use, the VCCS client control panel uses a touch screen system. AirNav Indonesia Manado Branch has a LESS brand VCCS equipment server manufactured by China. VCCS consists of two main parts, namely the server and client. The server is a processing center and control center for switching input and output, while the client or VCU (Voice Control Unit) is the device used by the user in VCCS operations. There are 7 VCUs at AirNav Indonesia Manado which are placed in the Tower room (3 VCU), APP room (3 VCU), and FSS Kompen room (1 VCU).

Speed Reading in the Dark: Accelerating Functional Encryption for Quadratic Functions with Reprogrammable Hardware
Authors: Bahadori Milad , Järvinen Kimmo , Marc Tilen , Stopar Miha
Published: July 2021

Functional encryption is a new paradigm for encryption where decryption does not give the entire plaintext but only some function of it. Functional encryption has great potential in privacy-enhancing technologies but suffers from excessive computational overheads. We introduce the first hardware accelerator that supports functional encryption for quadratic functions. Our accelerator is implemented on a reprogrammable system-on-chip following the hardware/software codesign methogology. We benchmark our implementation for two privacy-preserving machine learning applications: (1) classification of handwritten digits from the MNIST database and (2) classification of clothes images from the Fashion MNIST database. In both cases, classification is performed with encrypted images. We show that our implementation offers speedups of over 200 times compared to a published software implementation and permits applications which are unfeasible with software-only solutions.
Security and Trust in Open Source Security Tokens
Authors: Schink Marc , Wagner Alexander , Unterstein Florian , Heyszl Johann
Published: July 2021

Using passwords for authentication has been proven vulnerable in countless security incidents. Hardware security tokens effectively prevent most password-related security issues and improve security indisputably. However, we would like to highlight that there are new threats from attackers with physical access which need to be discussed. Supply chain adversaries may manipulate devices on a large scale and install backdoors before they even reach end users. In evil maid scenarios, specific devices may even be attacked while already in use. Hence, we thoroughly investigate the security and trustworthiness of seven commercially available open source security tokens, including devices from the two market leaders: SoloKeys and Nitrokey. Unfortunately, we identify and practically verify significant vulnerabilities in all seven examined tokens. Some of them are based on severe, previously undiscovered, vulnerabilities of two major microcontrollers which are used at a large scale in various products. Our findings clearly emphasize the significant threat from supply chain and evil maid scenarios since the attacks are practical and only require moderate attacker efforts. Fortunately, we are able to describe software-based countermeasures as effective improvements to retrofit the examined devices. To improve the security and trustworthiness of future security tokens, we also derive important general design recommendations.
AES-LBBB: AES Mode for Lightweight and BBB-Secure Authenticated Encryption
Authors: Naito Yusuke , Sasaki Yu , Sugawara Takeshi
Published: July 2021

In this paper, a new lightweight authenticated encryption scheme AESLBBB is proposed, which was designed to provide backward compatibility with advanced encryption standard (AES) as well as high security and low memory. The primary design goal, backward compatibility, is motivated by the fact that AES accelerators are now very common for devices in the field; we are interested in designing an efficient and highly secure mode of operation that exploits the best of those AES accelerators. The backward compatibility receives little attention in the NIST lightweight cryptography standardization process, in which only 3 out of 32 round-2 candidates are based on AES. Our mode, LBBB, is inspired by the design of ALE in the sense that the internal state size is a minimum 2n bits when using a block cipher of length n bits for the key and data. Unfortunately, there is no security proof of ALE, and forgery attacks have been found on ALE. In LBBB, we introduce an additional feed from block cipher’s output to the key state via a certain permutation λ, which enables us to prove beyond-birthday-bound (BBB) security. We then specify its AES instance, AES-LBBB, and evaluate its performance for (i) software implementation on a microcontroller with an AES coprocessor and (ii) hardware implementation for an application-specific integrated circuit (ASIC) to show that AES-LBBB performs better than the current state-of-the-art Remus-N2 with AES-128.
Attacking and Defending Masked Polynomial Comparison for Lattice-Based Cryptography
Authors: Bhasin Shivam , D’Anvers Jan-Pieter , Heinz Daniel , Pöppelmann Thomas , Van Beirendonck Michiel
Published: July 2021

In this work, we are concerned with the hardening of post-quantum key encapsulation mechanisms (KEM) against side-channel attacks, with a focus on the comparison operation required for the Fujisaki-Okamoto (FO) transform. We identify critical vulnerabilities in two proposals for masked comparison and successfully attack the masked comparison algorithms from TCHES 2018 and TCHES 2020. To do so, we use first-order side-channel attacks and show that the advertised security properties do not hold. Additionally, we break the higher-order secured masked comparison from TCHES 2020 using a collision attack, which does not require side-channel information. To enable implementers to spot such flaws in the implementation or underlying algorithms, we propose a framework that is designed to test the re-encryption step of the FO transform for information leakage. Our framework relies on a specifically parametrized t-test and would have identified the previously mentioned flaws in the masked comparison. Our framework can be used to test both the comparison itself and the full decapsulation implementation.
Cutting Through the Complexity of Reverse Engineering Embedded Devices

Published: July 2021

Performing security analysis of embedded devices is a challenging task. They present many difficulties not usually found when analyzing commodity systems: undocumented peripherals, esoteric instruction sets, and limited tool support. Thus, a significant amount of reverse engineering is almost always required to analyze such devices. In this paper, we present Incision, an architecture and operating-system agnostic reverse engineering framework. Incision tackles the problem of reducing the upfront effort to analyze complex end-user devices. It combines static and dynamic analyses in a feedback loop, enabling information from each to be used in tandem to improve our overall understanding of the firmware analyzed. We use Incision to analyze a variety of devices and firmware. Our evaluation spans firmware based on three RTOSes, an automotive ECU, and a 4G/LTE baseband. We demonstrate that Incision does not introduce significant complexity to the standard reverse engineering process and requires little manual effort to use. Moreover, its analyses produce correct results with high confidence and are robust across different OSes and ISAs.

Providing Qard Hasan from Zakat Fund for Non-Recipients of Zakat: A Shariah Analysis Study
Authors: Zakariyah Habeebullah , Abdulrahman Mansab Mahsen
Published: July 2021

Zakat is one of the pillars of Islam, it is considered as Islamic financial system. The paper aims at discussing the opinions of Muslim scholars regarding the permissibility of granting a soft loan from the Zakat sources; by spending their resources in ways that are not specified by the Qur’an, and the Sunnah. The research methodology applied in this paper is analytical and inductive methods which are adopted to study the view of classical and contemporary scholars, and to analyzing the views of advanced and contemporary jurists. Muslim scholars have different opinions regarding the permissibility of granting a soft loan from the Zakat sources based to various doctrines as follows: the first opinion States that it is permissible to grant soft loan using zakat revenues; this opinion was supported by Al-Maududi, Abdulrahman khalaf and Abu-Zuhra among others. The Second opinion says that it is forbidden to grant soft loan using zakat revenues; this was seconded by Rafiq Yunuss, Jadal Al-hāqī and others. The Third opinion states that it is permissible to grant soft loan using zakat revenues with specific conditions. The proponents of this were Abu satar, Muḥāmād Azukheil and among others. The study concludes with major results as follows: It is not permissible to use zakat revenues without specific aims set up for it; because it is violation of the Quranic text and the intent of Islamic Sharia of Zakat expenditures. The paper recommended to Zakat institutions to establish a fund to povide Qard Hasan to non Zakat recipients.

Authors: Bondar D.S. , Maslov V.I. , Onishchenko I.N.
Published: July 2021

Using 2d3v code LCODE, the numerical simulation of nonlinear wakefield excitation in plasma by shaped relativistic electron bunch with charge distribution, which increases according to Gaussian charge distribution up to the maximum value, and then decreases sharply to zero, has been performed. Transformer ratio, as the ratio of the maximum accelerating field to the maximum decelerating field inside the bunch, and accelerating the wakefield have been investigated taking into account nonlinearity of the wakefield. The dependence of the transformer ratio and the maximum accelerating field on the length of the bunch was investigated with a constant charge of the bunch. It was taken into account that the length of the nonlinear wakefield increases with increasing length of the bunch. It is shown that the transformer ratio reaches its maximum value for a certain length of the bunch. The maximum value of the transformer ratio reaches six as due to the profiling of the bunch, and due to the nonlinearity of the wakefield.

47Sc is considered as a promising beta-emitter for cancer immunotherapy. For its carrier-free production, the 48Ti(γ,p)47Sc reaction in the field of bremsstrahlung radiation of an electron accelerator can be used. On the basis of developed analytical model and a double-foil activation technique, the main characteristics of the photonuclear isotope production and optimal dimensions of a production target have been established. The measured photonuclear yield of 47Sc and dominant scandium admixtures in thin foils of natural titanium in the electron energy range of 35 to 95 MeV enabled to specify the available data on the cross-section of the48Ti(γ,p)47Sc reaction. Using those results, the gross and specific activity of 47Sc in the cylindrical titanium targets of optimal size were calculated by a simulation technique. The comparison of capacity of the photonuclear method of the 47Sc production with other techniques is carried out.

Made of austenitic steel at the NSC KIPT, the supercritical water convection loop Loop-1a was running for more than 500 hours in the first experimental session (in 2011). The materials tested in the loop were placed into a stream of water (more than 50 g/s) at a temperature of 350…400°C, a pressure of 23…25 MPa, and were irradiated by an electron beam with an energy of 10 MeV. Sediments that emerged on the inner surface of the loop were examined. The sediment mainly consisted of compounds of calcium and iron mixed with other elements. There is a possibility to increase corrosion induced by radiation due to dislocation damage, hydrogenation of metal and under the impact of active oxygen.
