RELEVANSI KONSEP PERPAJAKAN MENURUT ABU YUSUF DAN IBNU KHALDUN TERHADAP PEREKONOMIAN DI INDONESIA
Authors: Misbahul Ali
Published: November 2021

Tax is one of the most important instruments in the development of a country. This is because the development budget and government operations have a heavy dependence on taxes. However, at this time, the ratio of tax revenue in Indonesia is relatively small. This of course will have a bad impact on the country's development, given the expenditure budget whose contribution ratio is getting bigger. The lack of tax revenue is caused by a lack of public awareness in paying taxes and the rampant corrupt practices that exist in this country. Abu Yusuf and Ibn Khaldun with their intellect which is based on Islamic teachings by considering mashlahah and justice, managed to come up with tax theories that are relevant to the economy in Indonesia today. There are several tax theories according to Abu Yusuf and Ibn Khaldun which are considered relevant and can be a solution for the economy in Indonesia. Among them, the muqasamah system if applied today is still very relevant, especially the self-assessment system currently in effect in Indonesia that allows taxpayers to cheat. The Usyur that was in effect at the time of Abu Yusuf if it is relevant to the present, has several similarities with the collection of customs taxes

The existence of UMKM is very urgent for the community because it can provide solutions for workers who have not been accommodated. This is because UMKM are businesses that come from someone's creative thinking and do not have high criteria in absorbing labor. The reality is that UMKM have been able to survive in the welfare of people's lives both under normal conditions or in conditions of economic crisis, in fact in the 1997 economic crisis UMKM were able to provide solutions and continue to survive until economic conditions returned to stable. Along with the rapid development of UMKM, it often causes local conflicts and so on, to prevent this it is necessary to take preventive actions taken by the government against UMKM based on sharia principles. To realize UMKM that are in accordance with sharia principles, it is necessary to involve the government to make regulations related to the technical and implementation of UMKM. The standards for sharia UMKM are UMKM that have implemented sharia principles. There are five aspects that must be guarded by humans, namely religion (حفظ الين) soul (حفظ النفس) intellect (حفظ العقل) offspring (حفظ النسل) property (حفظ المال).

Published: November 2021

Motivated by the continuous but inconclusive and ambiguous evidence on the relationship between board diversity and financial performance, this study aimed at providing new evidence that will enhance the state of knowledge by establishing if board diversity affects the financial performance of listed Banking institutions in Nigeria. The key dependent variables of interest were Return on Assets (ROA) and Return on Equity (ROE) and the independent variables of interest were board gender diversity and board independence. The study sampled 12 listed banks from the Nigerian stock exchange and relied on secondary data from the Bloomberg database and the annual reports of the banking institutions. Panel data methodology was used to analyse the data for the period under review (2015-2019). The results of the study indicated that board gender diversity has a significant positive impact on both ROA and ROE of the banking institutions. Conversely, the findings of the study indicated that board independence has a significant negative impact on both ROA and ROE of banking institutions. The findings of this study are related to Agency and Resource dependence theories and will contribute to meaningful policy reforms that can improve corporate governance, especially in the banking industry. The results of the study strongly recommend the need to increase the number of female directors on the boards of banking institutions. The study further recommends ways in which the contributions of both female and independent directors can be promoted in other to benefit from their presence on the board.

Published: November 2021

Diabetes is a disease that affects how your body processes blood sugar and is often referred to as diabetes mellitus. Insulin insufficiency and ineffective insulin use coincide when the pancreas cannot produce enough insulin or the human body cannot use the insulin that is produced. Insulin is a hormone produced by the pancreas that helps in the transport of glucose from food into cells for use as energy. The common effect of uncontrolled diabetes is hyper-glycemia, or high blood sugar, which plus other health concerns, raises serious health issues, majorly towards the nerves and blood vessels. According to 2014 statistics, people aged 18 or older had diabetes and, according to 2019 statistics, diabetes alone caused 1.5 million deaths. However, because of the rapid growth of machine learning(ML) and deep learning (DL) classification algorithms. indifferent sectors, like health science, it is now remarkably easy to detect diabetes in its early stages. In this experiment, we have conducted a comparative analysis of several ML and DL techniques for early diabetes disease prediction. Additionally, we used a diabetes dataset from the UCI repository that has 17 attributes, including class, and evaluated the performance of all proposed machine learning and deep learning classification algorithms using a variety of performance metrics. According to our experiments, the XGBoost classifier outperformed the rest of the algorithms by approximately 100.0%, while the rest of the algorithms were over 90.0% accurate.
Improving Small Objects Detection using Transformer
Authors: Dubey Shikha , Olimov Farrukh , Rafique Muhammad Aasim , Jeon Moongu
Published: November 2021

General artificial intelligence is a trade-off between the inductive bias of an algorithm and its out-of-distribution generalization performance. The conspicuous impact of inductive bias is an unceasing trend of improved predictions in various problems in computer vision like object detection. Although a recently introduced object detection technique, based on transformers (DETR), shows results competitive to the conventional and modern object detection models, its accuracy deteriorates for detecting small-sized objects (in perspective). This study examines the inductive bias of DETR and proposes a normalized inductive bias for object detection using a transformer (SOF-DETR). It uses a lazy-fusion of features to sustain deep contextual information of objects present in the image. The features from multiple subsequent deep layers are fused with element-wise-summation and input to a transformer network for object queries that learn the long and short-distance spatial association in the image by the attention mechanism.
SOF-DETR uses a global set-based prediction for object detection, which directly produces a set of bounding boxes. The experimental results on the MS COCO dataset show the effectiveness of the added normalized inductive bias and feature fusion techniques by detecting more small-sized objects than DETR.

Published: November 2021

The phase scintillation index is a commonly used metric in the remote sensing of ionospheric irregularities. In this work, we analyze the phase scintillation index observed from the GPS, GLONASS, Galileo, and BeiDou satellite constellations, for a continuous period of three years. Our analysis reveals an elevated level of L1 phase scintillation observed from most GLONASS satellites, and non of the other GNSS constellations during the same period. This is of particular interest as the abnormality was observed during a solar minimum period, and from satellites labeled as healthy. Furthermore, the observations made were verified with data from three other receivers in different regions. This study was conducted to highlight these artificially induced phase scintillations from GLONASS satellites so that future studies can take them into considerations, especially during periods of heightened geomagnetic activity. Additionally, these artificially induced phase scintillations may result in loss of phase lock, as well as reduced positioning accuracy, which may have serious effects on the reliability and integrity of the GLONASS positioning service.

Vehicle Crash Mitigation Strategy in Unavoidable Collision Scenarios: Focusing on Motion Planning by Considering a Generalized Crash Severity Model
Authors: Li Daofei , Zhang Jiajie , Xiao Bin , Tang Binbin , Hu Zhaohan
Published: November 2021

Driving strategy in dynamic environment is crucial to the automated vehicle safety. In extremely emergency scenarios with unavoidable collision (UC), especially those with complex impact patterns, the potential crash risk should be well considered. This paper proposes a crash mitigation (CM) algorithm for UCs, which directly embeds a generalized crash severity index (CSI) model to vehicle-to-vehicle collisions of multiple impact patterns. The idea is that during the short time before a collision, the vehicle will actively adapt its position and poses to minimize the potential crash severity level after the collision. To this end, the generalized CSI model is introduced to estimate the potential crash severity of all sample paths, from which a crash-severity-optimal trajectory is obtained. To improve the inferring time efficiency of the planning module, a neural network is constructed and deployed to approximate the nonlinear severity model. The proposed algorithm is first validated through simulations of UC scenarios, including entry ramp merging, intersection crossing and downhill/uphill crossing. Then for the intersection crossing scenario, the algorithm is deployed to a real car and validated through digital-twin experiments. Results show that by combining the braking and steering interventions for better crash severity reduction, the proposed strategy can achieve better mitigation effects than commonly-used collision avoidance (CA) strategies. This reveals that a new mindset of comprehensive safety strategy should not focus only on CA, but also the last resort of CM if collision is unavoidable. Our work may contribute as a promising solution to the safety problem in emergency scenarios.
Motion Planning of Vehicles for Crash Mitigation in Emergency Driving Scenarios
Authors: Li Daofei , Hu Zhaohan
Published: November 2021

Motion
planning in dynamic environment is crucial to the automated driving safety. In
extremely emergency scenarios with unavoidable collisions, especially those with
complex impact patterns, the potential crash risk should be well considered in
motion planning. This paper proposes a motion planning algorithm for unavoidable
collisions, which directly embeds a generalized crash severity index model to
vehicle-to-vehicle collisions of multiple impact patterns. Firstly, the
clothoid curve is used to sample the vehicle trajectory before collision, and a
two-degree-of-freedom model is adopted to predict the vehicle poses
corresponding to each sample path. Then, the crash severity index model is to
estimate the potential crash severity of all sample paths. To improve the
inferring time efficiency, a neural network is constructed and deployed to
approximate the nonlinear severity model. Finally, the crash-severity-optimal
trajectory is tracked through model predictive control method. Results show
that by combining the braking and steering interventions for better crash
severity reduction, the proposed strategy can achieve better mitigation effects
than commonly-used collision-avoidance strategies. The deployment of real car
experiment and sensitivity analysis demonstrate that the planning algorithm can
guarantee real-time and reliably safe performances.
Identity-Preserving Pose-Robust Face Hallucination Through Face Subspace Prior
Authors: Abbasi Ali , Rahmati Mohammad
Published: November 2021

Over the past few decades, numerous attempts have been made to address the problem of recovering a high-resolution (HR) facial image from its corresponding low-resolution (LR) counterpart, a task commonly referred to as face hallucination. Despite the impressive performance achieved by position-patch and deep learning-based methods, most of these techniques are still unable to recover identity-specific features of faces. The former group of algorithms often produces blurry and oversmoothed outputs particularly in the presence of higher levels of degradation, whereas the latter generates faces which sometimes by no means resemble the individuals in the input images. In this paper, a novel face super-resolution approach will be introduced, in which the hallucinated face is forced to lie in a subspace spanned by the available training faces. Therefore, in contrast to the majority of existing face hallucination techniques and thanks to this face subspace prior, the reconstruction is performed in favor of recovering person-specific facial features, rather than merely increasing image quantitative scores. Furthermore, inspired by recent advances in the area of 3D face reconstruction, an efficient 3D dictionary alignment scheme is also presented, through which the algorithm becomes capable of dealing with low-resolution faces taken in uncontrolled conditions. In extensive experiments carried out on several well-known face datasets, the proposed algorithm shows remarkable performance by generating detailed and close to ground truth results which outperform the state-of-the-art face hallucination algorithms by significant margins both in quantitative and qualitative evaluations.
Tuning Successive Linear Programming to Solve AC Optimal Power Flow Problem for Large Networks
Authors: Sadat Sayed Abdullah , Sahraei-Ardakani mostafa
Published: November 2021

Successive linear programming (SLP) is a practical approach for solving large-scale nonlinear optimization problems. Alternating current optimal power flow (ACOPF) is no exception, particularly the large size of real-world networks. However, in order to achieve tractability, it is essential to tune the SLP algorithm presented in the literature. This paper presents a modified SLP algorithm to solve the ACOPF problem, specified by the U.S. Department of Energy's (DOE) Grid Optimization (GO) Competition Challenge 1, within strict time limits. The algorithm first finds a near-optimal solution for the relaxed problem (i.e., Stage 1). Then, it finds a feasible solution in the proximity of the near-optimal solution (i.e., Stage 2 and Stage 3). The numerical experiments on test cases ranging from 500-bus to 30,000-bus systems show that the algorithm is tractable. The results show that our proposed algorithm is tractable and can solve more than 80\% of test cases faster than the well-known Interior Point Method while significantly reduce the number of iterations required to solve ACOPF. The number of iterations is considered an important factor in the examination of tractability which can drastically reduce the computational time required within each iteration.
Aerial Intelligent Reflecting Surface Enabled Terahertz Covert Communications in Beyond-5G Internet of Things
Authors: Tatar Mamaghani Milad , Hong Yi
Published: November 2021

Unmanned aerial vehicles (UAVs) are envisioned to be extensively employed for assisting wireless communications in Internet of Things (IoT).

On the other hand, terahertz (THz) enabled intelligent reflecting surface (IRS) is expected to be one of the core enabling technologies for forthcoming beyond-5G wireless communications that promise a broad range of data-demand applications. In this paper, we propose a UAV-mounted IRS (UIRS) communication system over THz bands for confidential data dissemination from an access point (AP) towards multiple ground user equipments (UEs) in IoT networks. Specifically, the AP intends to send data to the scheduled UE, while unscheduled UEs may behave as potential adversaries. To protect information messages and the privacy of the scheduled UE, we aim to devise an energy-efficient multi-UAV covert communication scheme, where the UIRS is for reliable data transmissions, and an extra UAV is utilized as a cooperative jammer generating artificial noise (AN) to degrade unscheduled UEs detection, improving communication covertness.

This poses a novel max-min optimization problem in terms of minimum average energy efficiency (mAEE), targetting to improve covert throughput and reduce UAVs' propulsion energy consumption subject to some practical constraints such as covertness which is determined analytically. Since the optimization problem is non-convex, we tackle it via the block successive convex approximation (BSCA) approach to iteratively solve a sequence of approximated convex sub-problems, designing the binary user scheduling, AP's power allocation, maximum AN jamming power, IRS beamforming, and both UAVs' trajectory and velocity planning. Finally, we present a low-complex overall algorithm for system performance enhancement with complexity and convergence analysis. Numerical results are provided to verify our analysis and demonstrate significant outperformance of our design over other existing benchmark schemes.
Il viaggio come paradigma esistenziale nella Bibbia e nella letteratura ebraica antica
Authors: Zatelli Ida
Published: November 2021

The divine command issued to Abraham in Genesis 12,1: «Go (lek-lekà) from your country and your kindred and your father’s house to the land that I will show you», presents us with a dramatic image of the human existence as it unfolds in the Bible and in the ancient Hebrew texts. It is a departure for an undisclosed destination from which there is no coming back, an act of unconditional trust. The patriarchs describe themselves as wanderers and nomads (see Genesis 47,9) and the road (derek), the way becomes a metaphor for life. True life lies beyond the known world; only those who take upon themselves to embark on a long and perilous journey will see the “promised land” towards which Israel’s and humanity’s adventure leads.
I viaggi in un romanzo e i viaggi di un romanzo nel basso medioevo. Il caso del Joufroi de Poitiers
Authors: Manetti Roberta
Published: November 2021

In the fiction of the Joufroi de Poitiers, the author, perhaps a native of eastern France, claims to have found his story near Montpellier. His journey is perhaps not imaginary as we have an indication of a place that carries a certain political value, in an era when the French Crown, after having concluded the anti-Albigensian crusade in the mid-thirteenth century, had taken possession of the Midi. Montpellier was likely a free zone for the production and circulation of works of anti-Capetian satire, such as the Occitan novel which goes under the modern title of Flamenca. In fact, composed in the entourage of James I of Aragon in Montpellier, the Flamenca is one of the probable sources of Joufroi de Poitiers.
L’Asia orientale vista con gli occhi di viaggiatori italiani del secolo XVI
Authors: Rosa Cristina
Published: November 2021

The Italian travellers to the East during the 16th century left us some important works that they elaborated after their return to their homeland, works whose declared motivation was not only to leave a tangible memory of their life experiences but also to offer the cultured public of Old Europe and people interested in those geographical areas for professional reasons, useful material for a better understanding of the world. These texts, produced in accordance with certain literary canons that were already relatively well defined, are often documents capable of testifying to travel experiences in the era of the great geographical explorations in the Far East after Vasco da Gama’s voyage.
Navegações, descobertas, encontros e reencontros na poesia de Sophia de Mello Breyner Andresen
Authors: Loureiro La Salette
Published: November 2021

Sophia de Mello Breyner Andresen’s book Navigations was inspired by the experience of the author’s first contact with the East, during a plane trip to Macao to pay homage to Camões. The view of the coasts of Vietnam will have led Sophia to imagine the wonder and astonishment experienced by the Portuguese navigators who first arrived there by sea. Therefore, this book commemorates the Portuguese Discoveries, in the line of Camões and Pessoa, but that takes a new and original look on the theme. Therefore, these Navigations are an initiatory journey, from which results the discovery of Being, that is, in some way, a kind of circumnavigation voyage, the return to the beginning.
Il viaggio fantastico di de Chirico, Savinio, Landolfi
Authors: Spignoli Teresa
Published: November 2021

The intervention addresses three metaphysical and fantastical exemplary works from the twentieth century - Ebdòmero, La partenza dell’Argonauta, Il Mar delle Blatte – in which the theme of travel finds expression through different textual models. In the first case, De Chirico uses the archetypical model of Ulysses’ journey against a background of fantastic metaphysical imagery. In the second Savinio creates a parodistic rewriting of the Argonautiche by Apollonio Rodio – the mythical trip par excellence, while in the third (Il mar delle blatte) Landolfi recalls the characters of Salgari’s adventure novels. All three texts represent imaginary travels towards an unreachable elsewhere, symbolically represented by a paradisiacal Island, lost and dreamt of also by the sailor Pessoa.

Published: November 2021

Five-star hotel restaurants in the Nusa Dua area managed by international chains have similarities, namely not achieved the restaurant sales targets set by the company, restaurants not being remembered and known by consumers, restaurants not being advertised in various media, and TripAdvisor rankings, bubble ratings, and reviews are low. The above phenomena are related to the theory of word-of-mouth communication, advertising, brand awareness, and purchase intention. Research is conducted on the effect of word-of-mouth communication and advertising on purchase intention with brand awareness as a mediating variable. This type of research is explanatory research with non-probability purposive sampling technique with data collection techniques through questionnaires. Questionnaires were distributed to customers who had stayed and visited Eight Degrees South Conrad Bali and The Shore Hilton Bali for a period of one month from July 2021 to August 2021. The respondents who answered the questionnaire were 170 respondents. SEM PLS analysis was used to analyze the data. This study found that brand awareness has a positive and significant effect on purchase intention. WOM and advertising have no significant effect on purchase intention. WOM and advertising have a positive and significant effect on brand awareness. Brand awareness significantly mediates WOM and advertising on purchase intention. Restaurant managers are advised to advertise hotel restaurants on social media and advertorial advertisements to build brand awareness and consumer purchase intentions. Future research to explore the possibility of being developed in the room and spa division.
