Creators: name: Nik Tehrani
Publisher: name: Zenodo
Year: 2024

description: Among the new technologies currently positively used in manufacturing are augmented reality/virtual reality, 3D Printing, artificial technology, and nanotechnology. An AR|HUD system displays perspective-accurate surrounding information for a user to visualize 3D.Digital instructions are more detailed due to workers being allowed to see moving digital pieces being projected onto the work surface, reducing errors and stress.Industry 4, also referred to as the Fourth Industrial Revolution or 4I, is the next phase in the digitization of the manufacturing sector.Personalization and customization of products can be easily enabled with the low-volume production capabilities offered by on-demand additive manufacturing, creating an object by building it one layer at a time. Burst pressure tests on small numbers of products can identify weak points in product materials that could compromise performance, quality, or safety. AI is designed to accomplish tasks without explicit programming instructions.Nanotechnology is manipulating matter on a near-atomic scale to create new structures, devices, and materials.

description: As part of an effort to understand the origin of open clusters, we present a statistical analysis of the currently observed Pleiades. Starting with a photometric catalog of the cluster, we employ a maximum likelihood technique to determine the mass distribution of its members, including single stars and both components of binary systems. We find that the overall binary fraction for unresolved pairs is 68%. Extrapolating to include resolved systems, this fraction climbs to about 76%, significantly higher than the accepted field-star result. Both figures are sensitive to the cluster age, for which we have used the currently favored value of 125 Myr. The primary and secondary masses within binaries are correlated, in the sense that their ratios are closer to unity than under the hypothesis of random pairing. We map out the spatial variation of the cluster's projected and three-dimensional mass and number densities. Finally, we revisit the issue of mass segregation in the Pleiades. We find unambiguous evidence of segregation, and introduce a new method for quantifying it.

description: Software-defined metamaterials (SDMs) represent a novel paradigm for real-time control of metamaterials. SDMs are envisioned to enable a variety of exciting applications in the domains such as smart textiles and sensing in challenging conditions. Many of these applications envisage deformations of the SDM structure (e.g., rolling, bending, stretching). This affects the relative position of the metamaterial elements and requires their localization relative to each other. The question of how to perform such localization is, however, yet to spark in the community. We consider that the metamaterial elements are controlled wirelessly through a Terahertz (THz)-operating nanonetwork. Moreover, we consider the elements to be energy constrained, with their sole powering option being to harvest environmental energy. For such a setup, we demonstrate sub-millimeter accuracy of the two-way Time of Flight (ToF)-based localization, as well as high availability of the service (i.e., consistently more than 80% of the time), which is a result of the low energy consumed in localization. Finally, we provide the localization context for a number of relevant system parameters such as operational frequency, bandwidth, and harvesting rate.

Design and Implementation of an Online Electricity Payment and Metering System with Payment Integration, Emailing and SMS
Creators: name: Oparanwata Chidi Cosmas
Publisher: name: Zenodo
Year: 2024

description: Nigeria's energy sector is plagued by poor, inadequate and disorganized electricity billing and consumer relations management. Despite the introduction of prepaid billing meters, electricity billing and collection remains a major challenge in some communities in Nigeria. Because the electricity consumer must first go to the bank to make the payment and then take the cashier to the electricity company's office to confirm the electricity payment before the electricity is applied to the card. The installment and payment process is tedious and burdensome. The main objective of this research is to design and implement a practical, cashless, automated and transparent electricity metering, billing and payment system.  This study combines the power of the Internet to allow a power meter to communicate with her SMS and email network. Once fully implemented, the proposed system will allow electricity consumers to seamlessly charge and pay their electricity bills remotely via their mobile phones or laptops. The introduction of an online electricity payment and meter reading system will help improve accountability, organize and simplify electricity payments in Nigeria. The proposed system was developed using HTML and CSS, as well as Python and MySQL programming languages.

We have developed a fully time-dependent and three-dimensional code adapted for the wavy heliospheric current sheet (HCS). Results anticipated by the drift pattern are obtained for sample trajectories and distributions of arrival points at the heliospheric boundary for GCR protons. Our simulation reproduced a 22-year cycle of solar modulation which is qualitatively consistent with observations. Energy spectra of protons at 1 AU are calculated and compared with the observation by BESS.

description: Methods. The northern-eastern fringe of the Chameleon I dark cloud was observed with XMM-Newton, revisiting a region observed with ROSAT 15 years ago. Centered on the extended X-ray source CHXR49 we are able to resolve it into three major contributing components and to analyse their spectral properties. Furthermore, the deep exposure allows not only the detection of numerous, previously unknown X-ray sources, but also the investigation of variability and the study of the X-ray properties for the brighter targets in the field. We use EPIC spectra, to determine X-ray brightness, coronal temperatures and emission measures for these sources, compare the properties of classical and weak-line T Tauri stars and make a comparison with results from the ROSAT observation. Results. X-ray properties of T Tauri stars in Cha I are presented. The XMM-Newton images resolve some previously blended X-ray sources, confirm several possible ones and detect many new X-ray targets, resulting in the most comprehensive list with 71 X-ray sources in the northern Cha I dark cloud. The analysis of medium resolution spectra shows an overlapping distribution of spectral properties for classical and weak-line T Tauri stars, with the X-ray brighter stars having hotter coronae and a higher L_X/L_bol ratio. X-ray luminosity correlates with bolometric luminosity, whereas the L_X/L_bol ratio is slightly lower for the classical T Tauri stars. Large flares as well as a low iron and a high neon abundance are found in both types of T Tauri stars. Abundance pattern, plasma temperatures and emission measure distributions during quiescent phases are attributed toa high level of magnetic activity as the dominant source of their X-ray emission.

Analyzing Adaptive Parameter Landscapes in Parameter Adaptation Methods for Differential Evolution
Creators: name: Tanabe, Ryoji
Publisher: name: arXiv
Year: 2020
Subjects: subject: Neural and Evolutionary Computing (cs.NE)
subject: FOS: Computer and information sciences

description: Since the scale factor and the crossover rate significantly influence the performance of differential evolution (DE), parameter adaptation methods (PAMs) for the two parameters have been well studied in the DE community. Although PAMs can sufficiently improve the effectiveness of DE, PAMs are poorly understood (e.g., the working principle of PAMs). One of the difficulties in understanding PAMs comes from the unclarity of the parameter space that consists of the scale factor and the crossover rate. This paper addresses this issue by analyzing adaptive parameter landscapes in PAMs for DE. First, we propose a concept of an adaptive parameter landscape, which captures a moment in a parameter adaptation process. For each iteration, each individual in the population has its adaptive parameter landscape. Second, we propose a method of analyzing adaptive parameter landscapes using a 1-step-lookahead greedy improvement metric. Third, we examine adaptive parameter landscapes in PAMs by using the proposed method. Results provide insightful information about PAMs in DE.

description: Magnetic braking (MB) likely plays a vital role in the evolution of low-mass X-ray binaries (LMXBs). However, it is still uncertain about the physics of MB, and there are various proposed scenarios for MB in the literature. To examine and discriminate the efficiency of MB, we investigate the LMXB evolution with five proposed MB laws. Combining detailed binary evolution calculation with binary population synthesis, we obtain the expected properties of LMXBs and their descendants binary millisecond pulsars. We then discuss the strength and weakness of each MB law by comparing the calculated results with observations. We conclude that the $τ$-boosted MB law seems to best match the observational characteristics.

description: The International Telecommunication Union (ITU) is currently deliberating on the finalization of candidate radio interface technologies (RITs) for IMT-2020 (International Mobile Telecommunications) suitability. The candidate technologies are currently being evaluated and after a couple of ITU-Radiocommunication sector (ITU-R) working party (WP) meetings, they will become official. Although, products based on the candidate technology from 3GPP (5G new radio (NR)) is already commercial in several operator networks, the ITU is yet to officially declare it as IMT-2020 qualified. Along with evaluation of the 3GPP 5G NR specifications, our group has evaluated many other proponent technologies. 3GPP entire specifications were examined and evaluated through simulation using Matlab and using own developed simulator which is based on the Go-language. The simulator can evaluate complete 5G NR performance using the IMT-2020 evaluation framework. In this work, we are presenting latency parameters which has shown some minor differences from the 3GPP report. Especially, for time division duplexing (TDD) mode of operation, the differences are observed. It might be possible that the differences are due to assumptions made outside the scope of the evaluation. However, we considered the worst case parameter. Although, the report is submitted to ITU but it is also important for the research community to understand why the differences and what were the assumptions in scenario for which differences are observed.

description: We investigate the superconducting properties and possible nematic superconductivity of self-doped BiCh2-based (Ch: S, Se) superconductor CeOBiS1.7Se0.3 through the measurements of in-plane anisotropy of magnetoresistance. Single crystals of CeOBiS1.7Se0.3 were grown using a flux method. Single-crystal structural analysis revealed that the crystal structure at room temperature is tetragonal (P4/nmm). Bulk superconductivity with a transition temperature of 3.3 K was observed through electrical resistivity and magnetization measurements. Investigation of anisotropy of upper critical field suggested relatively low anisotropy in the crystal as compared to other BiCh2-based superconductors. In the superconducting states of CeOBiS1.7Se0.3, two-fold symmetric in-plane anisotropy of magnetoresistance was observed, which indicates the in-plane rotational symmetry breaking in the tetragonal structure and hence the possibility of nematic superconductivity in CeOBiS1.7Se0.3.

description: As defined in the SSHOC workplan, task 2.3 SSHOC web presence will cover all activities related to the design, development, roll-out and continuous update of the SSHOC web presence. An evolved SSHOC web platform will ensure a service-oriented approach to the SSHOC marketplace developed in WP7 and will act as the main project entry point providing a multi-view of the SSH landscape, according to the main research lines of the ERICs involved, namely Art and Humanities, Social Science, Linguistics. The SSHOC web platform will be conceived and structured to ensure visibility and easy access to the technologies and services resulting from WP3, as well as innovations mechanisms in data production (WP4), use cases (WP5) and training materials (WP6), targeting data producers and data re-users in the SSH disciplines, as well as industry players. The web platform will also serve as main repository for all published content and allow access to project deliverables and external resources. It will have specific sections dedicated to events and workshops; it may contain sections to collect user feedbacks and online surveys. It will be able to optionally host any software repository developed within SSHOC and will provide direct access points to the ERICs websites and other relevant websites, existing catalogues and virtual labs. This task will also provide branding for the Marketplace (WP7) and support to improve its Graphical User Interface (GUI) and end-user friendliness. Specific branding of the new services will also be provided, making their look & feel homogeneous under the SSHOC umbrella. On 5 July 2019, the SSHOC web platform second release was published, and milestone 4 achieved. This second release of the SSHOC website aims to show the progress the project is making and prepare the website to provide visibility for the upcoming results. This iteration also paints the EOSC ecosystem and SSH landscape in which SSHOC operates. This document describes the achievement of SSHOC Milestone 4.
Performance of differentially detected GMSK in a mobile radio channel
Creators: name: Mok, William Chiu Hung
Publisher: name: University of British Columbia
Year: 2009

description: As the demand for current cellular voice-oriented networks to include other services such as data and video applications is increasing rapidly, the reliability of information transmission over the mobile radio environment is important. Performance evaluation in terms of the bit error rate (BER) and block (packet) error rate (BKER) of modulation schemes in such an environment is of considerable research interest. In this thesis, we study the BER as well as the BKER performance of Gaussian-filtered Minimum Shift Keying (GMSK) modulation, currently used in the Global System for Mobile Communication (GSM) standard, in additive white Gaussian noise (AWGN) as well as flat and frequency selective Rayleigh fading. 1-bit and 2-bit differential detectors are used for demodulation. A detailed analysis is carried out to examine the IF filtering effect on the BER performance over the fading channels. The BKER performance is mainly studied through simulations. Since the premodulation Gaussian filter at the GMSK transmitter introduces significant Intersymbol Interference (ISI), we also examine the performance of a decision feedback (DF) scheme which partially removes the ISI, over such channels. The BER results in both flat and frequency selective (FS) Rayleigh fading show that 2-bit conventional (with no decision feedback) GMSK performs slightly better than 1-bit conventional GMSK when Eb/NQ < 25 dB. Above this value, the latter performs better and has a lower irreducible error. Results also show that 2-bit conventional GMSK is more sensitive to the IF filtering distortion than 1-bit conventional GMSK in Rayleigh fading. The percentage improvement in BKER of 1-bit DF GMSK over 1-bit conventional GMSK is almost equal to that of the corresponding BERs. In the case of 2-bit DF GMSK, the BKER performance shows an increased improvement over 2-bit conventional GMSK when compared to the corresponding BER performance, owing to increased error propagation. Since fading gives rise to bursty bit errors, the actual BKER is lower than the predicted assuming independent bit errors. In all fading cases, 1-bit conventional GMSK has a better BKER performance over 2-bit conventional GMSK when Eb/NQ >25 dB. In the case of decision feedback, similar performance trends are observed.

description: The phonon scattering processes on the three solid phases of ethanol are investigated by means of thermal conductivity, light and neutron scattering measurements as well as molecular dynamics simulations on single-crystalline models for the two crystalline modifications (fully ordered monooclinic and orientationally disordered bcc phases). The orientationally disordered crystal is found to exhibit a temperature dependence of the thermal conductivity that is remarkably close to that found for the structurally amorphous solid, specially at low temperatures. The results, together with measurements of the Brillouin linewidths as derived from light scattering measurements emphasize the role of orientational disorder on phonon scattering. The experimental results obtained on polycrystal samples are then discussed with the aid of computer simulations on single-crystalline models of both bcc and monoclinic crystals. Our findings are in good agreement with the wealth of thermodynamic and dynamic data vailable so far [1], but are in stark contrast with inferences made from the analysis of inelastic X-ray data on polycrystalline samples [2], where a common nature for the excitations in all phases is postulated.

description: The design of inhibitors specific for one relevant carbonic anhydrase isozyme is the major challenge in the new therapeutic agents development. Comparative computational chemical structure and biological activity relationship studies on a series of carbonic anhydrase II inhibitors, benzenesulfonamide derivatives, bearing pyrimidine moieties are reported in this paper using docking, Linear Interaction Energy (LIE), metadynamics and Quantitative Structure Activity Relationship (QSAR) methods. The computed binding affinities were compared with the experimental data with goal to find out the best method for the investigated carbonic anhydrase/inhibitor system. From those tested methods initially only QSAR showed promising results (R2=0.83-0.85 between experimentally determined versus predicted pKd values.). Possible reasons were discussed and two promising improvements were suggested: one is alternative equation for LIE-like method which was tried out and gave far better results (R2 between experimentally determined ΔGbind  versus predicted ΔGbind was improved from 0.24 into 0.50) and other for docking.

description: Coronavirus disease 2019 (COVID-19) has become a global pandemic infectious respiratory disease with high mortality and infectiousness. This paper investigates respiratory droplet transmission, which is critical to understanding, modeling and controlling epidemics. In the present work, we implemented flow visualization, particle image velocimetry (PIV) and particle shadow tracking velocimetry (PSTV) to measure the velocity of the airflow and droplets involved in coughing and then constructed a physical model considering the evaporation effect to predict the motion of droplets under different weather conditions. The experimental results indicate that the convection velocity of cough airflow presents the relationship $t^{-0.7}$ with time; hence, the distance from the cougher increases by $t^{0.3}$ in the range of our measurement domain. Substituting these experimental results into the physical model reveals that the small droplets (initial diameter $D \leq$ 100 $μ$m) evaporate to droplet nuclei and that the large droplets with $D \geq$ 500 $μ$m and initial velocity $u_0 \geq$ 5 m/s travel more than 2 m. Winter conditions of low temperature and high relative humidity can cause more droplets to settle to the ground, which may be a possible driver of a second pandemic wave in the autumn and winter seasons.

description: In the coming year, the Large Hadron Collider will begin colliding protons at energies nearly an order of magnitude beyond the current frontier. The LHC will, of course, provide unprecedented opportunities to discover new particle physics. Less well-known, however, is that the LHC may also provide insights about gravity and the early universe. I review some of these connections, focusing on the topics of dark matter and dark energy, and highlight outstanding prospects for breakthroughs at the interface of particle physics and cosmology.

Crypto-currency from an Islamic Perspective(Critical Analysis of Literature)
Creators: name: Zuhair Abdalrazzaq
Publisher: name: Zenodo

description: People have been exchanging goods since the beginning of time. At first, goods and services were exchanged through barter, then the system evolved and went through several phases until it finally reached the phase of digitalization of currency. Many discussions revolve around this. This study traces the development of exchange methods and examines the revolutionary concept of cryptocurrency, which is characterized by cryptography and block chain technology. The study aims to improve understanding, assess compatibility with Sharia law and clarify the acceptance of digital currencies in Islam: Through thorough library research, the study examines the legality of cryptocurrencies from an Islamic perspective, identifies trading requirements and outlines legal requirements. The findings highlight the transparency and efficiency of cryptocurrencies, coupled with concerns over potential illegal activities. Sharia compliance is deemed feasible under certain conditions, requiring the removal of ambiguity and speculation. Cryptocurrencies, which are stored and created electronically using block chain technology, use cryptographic processes to create monetary units and verify money transfers. Pending further development in line with Shariah transparency requirements, the study advocates a cautious perception and conditional acceptance of cryptocurrencies. Recommendations include further investigation and vigilance to ensure continued compliance with Shariah principles. The study makes a valuable contribution to the discourse on the legal and economic dimensions of cryptocurrencies for policy makers, academics and practitioners.

description: We study the evolution of the probability density of an asexual, one locus population under natural selection and random evolution. This evolution is governed by a Fokker-Planck equation with degenerate coefficients on the boundaries, supplemented by a pair of conservation laws. It is readily shown that no classical or standard weak solution definition yields solvability of the problem. We provide an appropriate definition of weak solution for the problem, for which we show existence and uniqueness. The solution displays a very distinctive structure and, for large time, we show convergence to a unique stationary solution that turns out to be a singular measure supported at the endpoints. An exponential rate of convergence to this steady state is also proved.

Short-Baseline Active-Sterile Neutrino Oscillations?

description: We suggest the possibility that the anomalies observed in the LSND experiment and the Gallium radioactive source experiments may be due to neutrino oscillations generated by a large squared-mass difference of about 20 - 30 eV^2. We consider the simplest 3+1 four-neutrino scheme that can accommodate also the observed solar and atmospheric neutrino oscillations. We show that, in this framework, the disappearance of nu_e and nu_mu in short-baseline neutrino oscillation experiments is mainly due to active-sterile transitions. The implications of the first MiniBooNE results, appeared after the completion of this paper, are discussed in an addendum.

Das dritte Jahrtausend im osteuropäischen Steppenraum

description: Grabhügel sind charakteristisch für die Jamnaja-Kultur und die Katakombengrabkultur des 3. Jahrtausend v. Chr. in der osteuropäischen Steppen- und Waldsteppenzone. Mit Beginn der Jamnaja-Kultur erfolgt die Beisetzung in Grabhügeln regelhaft , die Hügel werden häufig mehrfach benutzt und wachsen über die Zeit zu Monumenten heran. Auch die Wirtschaftsweise verändert sich in dieser Zeit, denn die Steppenbewohner spezialisieren sich in ihrer Subsistenz auf Rinderzucht. Damit sind sie offenbar so erfolgreich, dass im gesamten 3. Jahrtausend v. Chr. und in den darauf folgenden Jahrhunderten Rinder in den Herden dominieren. Die Jagd spielt nur noch eine sehr geringe Rolle. Im vorliegenden Buch werden die einzelnen Phasen der Jamnaja-Kultur und der Katakombengrabkultur umfassend relativ- und absolutchronologisch ausgewertet und ihre regionalspezifischen Ausprägungen sowie die sozialarchäologischen Potentiale ihrer archäologischen Hinterlassenschaften untersucht. Dabei spielen Formen der Mobilität und eine möglicherweise saisonale Nutzung von Siedlungen ebenso eine Rolle wie die Frage nach Migrationen aus dem Steppengebiet nach Südost- und Mitteleuropa.
Lie transformation on shortcut to adiabaticity in parametric driving quantum system

description: Shortcut to adiabaticity (STA) is a speed way to produce the same final state that would result in an adiabatic, infinitely slow process. Two typical techniques to engineer STA are developed by either introducing auxiliary counterdiabatic fields or finding new Hamiltonians that own dynamical invariants to constraint the system into the adiabatic paths. In this paper, a consistent method is introduced to naturally connect the above two techniques with a unified Lie algebraic framework, which neatly removes the requirements of finding instantaneous states in the transitionless driving method and the invariant quantities in the invariant-based inverse engineering approach. The general STA schemes for different potential expansions are concisely achieved with the aid of this method.

description: We define analogues of Verma modules for finite W-algebras. By the usual ideas of highest weight theory, this is a first step towards the classification of finite dimensional irreducible modules. Motivated by known results in type A, we then formulate some precise conjectures in the case of nilpotent orbits of standard Levi type.

description: Natural language processing (NLP) techniques have become mainstream in the recent decade. Most of these advances are attributed to the processing of a single language. More recently, with the extensive growth of social media platforms focus has shifted to code-mixed text. The code-mixed text comprises text written in more than one language. People naturally tend to combine local language with global languages like English. To process such texts, current NLP techniques are not sufficient. As a first step, the text is processed to identify the language of the words in the text. In this work, we focus on language identification in code-mixed sentences for Hindi-English mixed text. The task of language identification is formulated as a token classification task. In the supervised setting, each word in the sentence has an associated language label. We evaluate different deep learning models and input representation combinations for this task. Mainly, character, sub-word, and word embeddings are considered in combination with CNN and LSTM based models. We show that sub-word representation along with the LSTM model gives the best results. In general sub-word representations perform significantly better than other input representations. We report the best accuracy of 94.52% using a single layer LSTM model on the standard SAIL ICON 2017 test set.
