A Bayesian Approach to Risk-Based Autonomy for a Robotic System Executing a Sequence of Independent Tasks
Authors: Rothmund Sverre Velten , Thieme Christoph Alexander , Utne Ingrid Bouwer , Johansen Tor Arne
Published: September 2021

Enabling higher levels of autonomy requires an increased ability to identify and handle internal faults and unforeseen changes in the environment. This work presents an approach to improve this ability for a robotic system executing a series of independent tasks, such as inspection, sampling, or intervention, at different locations. A dynamic decision network (DDN) is used to infer the presence of internal faults and the state of the environment by fusing information over time. This knowledge is used to make risk-informed decisions enabling the system to proactively avoid failure and to minimize the consequence of faults. Past states are evaluated with new information to identify and counteract previous sub-optimal actions. A case study on an inspection drone tasked with contact-based ultrasound inspection is presented. The case study successfully demonstrates the proposed capabilities while minimizing time use and maximizing mission completion.
A Two-Stage 110VAC-to-1VDC Power Delivery Architecture Using Hybrid Converters for Data Centers and Telecommunication Systems
Authors: Das Ratul , Le Hanh-Phuc
Published: September 2021

Improving power delivery and management plays a key role in minimizing the cost of building and operating future green data centers to meet the fast growth of high-performance computing. Toward this important goal, this paper presents a new complete power delivery architecture to bridge AC grid voltages to core levels for computing loads using only 2 conversion stages with new converter topologies. The first stage converts a commercial AC line voltage of 90V-110V to a 48-60V intermediate bus with power factor correction (PFC). The second stage converts the bus voltage to core voltages of ~1 V with high current density and simple duty cycle control. Individually, the first stage was measured at 96.1% peak efficiency for output currents ranging in 0-4.5 A, while the second stage achieved 90.7% peak efficiency with a load range of 0-220 A at 1 V. Measured peak power densities are 73 W/in3 for the first stage and 2020 W/in3 for the second stage. In combination, the direct conversion from a line AC voltage of ~110 VAC to 1 VDC achieves a peak efficiency of 84.1% while providing output currents up to 160A.

Published: September 2021

The COVID-19 pandemic has emerged as the world's most serious health crisis, affecting millions of people all over the world. The majority of nations have imposed nationwide curfews and reduced economic activity to combat the spread of this infectious disease. Governments are monitoring the situation and making critical decisions based on the daily number of new cases and deaths reported. Therefore, this study aims to predict the daily new deaths using four tree-based ensemble models i.e., Gradient Tree Boosting (GB), Random Forest (RF), Extreme Gradient Boosting (XGBoost), and Voting Regressor (VR) for the three most affected countries, which are the United States, Brazil, and India. The results showed that VR outperformed other models in predicting daily new deaths for all three countries. The predictions of daily new deaths made using VR for Brazil and India are very close to the actual new deaths, whereas the prediction of daily new deaths for the United States still needs to be improved.

its variants. In this paper, we present a simple benchmark-
like formulation for exploiting Gaussian Process uncertainty for
sensor placement to measure a scalar field.
Differential Private Federated Learning for Privacy-Preserving Third Party Service Framework in Advanced Metering Infrastructure
Authors: Zhang Xiao-Yu , Cordoba-Pachon Jose , Watkins Chris , Kuenzel Stefanie
Published: September 2021

The advanced metering infrastructure (AMI) is a compulsory component of the future smart grid; it not only provides near real-time two-way communication between the consumers and the utility but also gives an opportunity to third parties to provide relevant value-added services to the consumers to improve the user satisfaction. However, existing services require the consumers share their private energy data with other parties, which has potential privacy risks. To better balance the excellent quality of the services and privacy guarantee, a novel differential private federated learning-based third-party service platform is proposed. Instead of sending the original energy data to the cloud server, the central server in the proposed scheme only collects the model parameters, which are trained locally inside the consumers’ houses. Then the collected parameters are aggregated differential privately to eliminate the identity of individuals, and the aggregated parameters are used to update the central model and improve the model performance. Furthermore, a novel attention-based bidirectional long short-term memory neural network model is adopted to make predictions. In the case study, a residential short term load forecasting task is implemented to evaluate the performance of the proposed model; from the simulation results, the conclusion is made that the proposed model can achieve similar accuracy as the typical centralized model and better control the privacy loss flexibly at the same time.
HaS-Net: A Heal and Select Mechanism to Securely Train DNNs against Backdoor Attacks
Authors: Ali Hassan , Nepal Surya , S. Kanhere Salil , Jha Sanjay K.
Published: September 2021

We have witnessed the continuing arms race between backdoor attacks and the corresponding defense strategies on Deep Neural Networks (DNNs). However, most state-of-the-art defenses rely on the statistical sanitization of inputs or latent DNN representations to capture trojan behavior. In this paper, we first challenge the robustness of many recently reported defenses by introducing a novel variant of the targeted backdoor attack, called low-confidence backdoor attack. Low-confidence attack inserts the backdoor by assigning uniformly distributed probabilistic labels to the poisoned training samples, and is applicable to many practical scenarios such as Federated Learning and model-reuse cases. We evaluate our attack against five state-of-the-art defense methods, viz., STRIP, Gradient-Shaping, Februus, ULP-defense and ABS-defense, under the same threat model as assumed by the respective defenses and achieve Attack Success Rates (ASRs) of 99\%, 63.73%, 91.2%, 80% and 100%, respectively. After carefully studying the properties of the state-of-the-art attacks, including low-confidence attacks, we present HaS-Net, a mechanism to securely train DNNs against a number of backdoor attacks under the data-collection scenario. For this purpose, we use a reasonably small healing dataset, approximately 2% to 15% the size of training data, to heal the network at each iteration. We evaluate our defense for different datasets---Fashion-MNIST, CIFAR-10, Celebrity Face, Consumer Complaint and Urban Sound---and network architectures---MLPs, 2D-CNNs, 1D-CNNs---and against several attack configurations---standard backdoor attacks, invisible backdoor attacks, label-consistent attack and all-trojan backdoor attack, including their low-confidence variants. Our experiments show that HaS-Nets can decrease ASRs from over 90% to less than 15%, independent of the dataset, attack configuration and network architecture.
An Inner Product Space-Based Hierarchical Key Assignment Scheme for Access Control
Authors: Celiktas Baris , Ozdemır Enver , Guzey Sueda
Published: September 2021

An inner product space-based hierarchical key assignment/access control scheme is presented in this work. The proposed scheme can be utilized in any cloud delivery model where the data controller implements a hierarchical access control policy. In other words, the scheme adjusts any hierarchical access control policy to a digital medium. The scheme is based on inner product spaces and the method of orthogonal projection. While distributing a basis for each class by the data controller, the left-to-right and bottom-up policy can provide much more flexibility and efficiency, especially during any dynamic update/change in the hierarchical structure. For each class, the secret keys can be derived only when a predetermined subspace is available. A parent class can obtain the secret keys of its child classes, which means a one-way function, and the opposite direction is not allowed. Our scheme is collusion attack and privilege creep problem resistant, as well as key recovery and indistinguishability secure. The performance analysis shows that the data storage overhead is more tolerable than other schemes in the literature. In addition, the other advantage of our scheme over many others in the literature is that it needs only one operation for the derivation of the secret key of child classes.

Numerical Performance of Different Formulations for Alternating Current Optimal Power Flow
Authors: Sadat Sayed Abdullah , Kim Kibaek
Published: September 2021

Alternating current optimal power flow (ACOPF) problems are nonconvex and nonlinear optimization problems. Utilities and independent service operators (ISO) require ACOPF to be solved in almost real time. Interior point methods (IPMs) are one of the powerful methods for solving large-scale nonlinear optimization problems and are a suitable approach for solving ACOPF with large-scale real-world transmission networks. Moreover, the choice of the formulation is as important as choosing the algorithm for solving an ACOPF problem. In this paper, different ACOPF formulations with various linear solvers and the impact of employing box constraints are evaluated for computational viability and best performance when using IPMs. Different optimization structures are used in these formulations to model the ACOPF problem representing a range of sparsity. The numerical experiments suggest that the least sparse ACOPF formulations with polar voltages yield the best computational results. Additionally, nodal injected models and current-based branch flow models are improved by enforcing box constraints. A wide range of test cases, ranging from 500-bus systems to 9591-bus systems, are used to verify the test results.

UTILIZATION OF DIFFERENT TYPES OF FIBRES CEMENTOUS MATERIALS AND SBR LATEX IN THE CONCRETE - A REVIEW
Authors: B. Kanna Babu  , Bimalendu Dash
Published: September 2021

Concrete’s tensile strength is low compared to its compressive strength when subjected to normal stresses and impact loads, making it brittle. Continuous reinforcing improves the strength and ductility of concrete, but it requires careful placement and the availability of labour. In this work, the impact of several types of concrete fibre characteristics was studied. The concept of using fibres to alter the characteristics of building materials isn’t new. When concrete cracks and randomly oriented fibres start to operate together, they prevent crack development and extension while also increasing strength and ductility. The current trend is to develop more effective crack-resistant concrete, such as reinforced fibre concrete. The geometric size and modulus of fibres are the key factors of the mechanical performance of fibre reinforced concrete. According to the findings, adding fibres to concrete enhances compressive strength, flexural strength, split tensile strength, ductility, and impact strength.
KEY WORDS: Nylon Fibre; Latex; Compressive Strength; Split Tensile Strength; Flexural Strength, Durability.

Shallots are one of the important commodities of high economic value in Indonesia. One of the obstacles in the production of shallots is the attack of pests and pathogens. The potential for yield loss due to pest and pathogen attacks can reach 20-100%. The research was carried out in the villages of Tegalarum, Sukorukun, and Sumberarum, Jaken District, Pati Regency from January to February 2021. The research used field observation methods, using swing nets to collect pests. This study aims to determine the types and diversity of pests in shallots cultivation in Jaken District, Pati Regency. The results of the research in the shallot plantations of Tegalarum and Sukorukun Villages found 3 species of pests, namely Liriomyza chinensis, Spodoptera exigua, and Bemisia tabaci. Meanwhile, in Sumberarum Village, 4 species of pests were found, namely Liriomyza chinensis, Spodoptera exigua, Bemisia tabaci, and Spodoptera litura. The diversity index (H') for Tegalarum and Sukorukun villages was low while Sumberarum villages were moderate. The evenness index (E) in the 3 villages is fairly evenly, while the species richness index (R) and dominance (D) for the three villages are low.
Principio de Devengado en materia tributaria
Authors: Choque Ticona Pedro José
Published: September 2021

El Impuesto a la Renta en Perú reconoce las rentas de tercera categoría (rentas empresariales y los gastos) en base al devengado; sin embargo, la legislación tributaria no ha definido lo que debe entenderse por este principio. La Superintendencia Nacional de Administración Tributaria, para el reconocimiento de las rentas, emplea en sus pronunciamientos lo establecido en las normas contables (Normas Internacionales de Información Financiera - NIIF). Las resoluciones del Tribunal Fiscal son sustentadas en base a lo establecido en las normas contables (NIIF); pero al momento de definir devengado, no emplean las normas contables sino doctrina jurídica. En el presente artículo se busca demostrar si es posible emplear las normas contables para definir el devengado en el ámbito tributario.

liderazgo humanista ético en las organizaciones
Authors: Aguilar Camacho Mario Jesús , Alonso Niño Edwin Hernando
Published: September 2021

Este trabajo de investigación se replantea el papel protagónico que le corresponde asumir a los líderes y sus seguidores para lograr un desempeño exitoso de las organizaciones actuales. La idea se genera una vez que han sido sometidos a fuerte valoración crítica y a ser considerados como agotados y rebasados algunos de los enfoques y modelos de liderazgo cimentados en teorías idealistas, empiristas, vitalistas, materialistas, conductistas, individualistas. Las conclusiones de arribo evidencian la necesidad de gestionar en las organizaciones un liderazgo transformador y humanista, sustentado en una filosofía realista, orientada sobre principios éticos, valores y competencias; en pocas palabras, un retorno al modelo de liderazgo “político” similar al de los griegos: al servicio de la comunidad, la polis.
Impacto sociocultural de la actividad mercadológica en el ser humano y la sociedad
Authors: Valdez Cornejo Ricardo Arturo
Published: September 2021

El presente trabajo trata acerca del impacto social y cultural de la actividad mercadológica empresarial, tomando como eje fundamental la actuación de las organizaciones y la sociedad con la que entran en contacto, la cual presenta cambios que pudieran resultar positivos o negativos, vistos desde un enfoque amplio y objetivo. Por otro lado, la sociedad también influye sobre la forma cómo las empresas llevan a cabo sus actividades de carácter mercadológico. Por tanto, existe una clara sinergia entre empresa y sociedad, la cual debiera ser aprovechada para generar maximización de valor compartido en un contexto de responsabilidad social corporativa y plena conducta ética.
A Quantitative Model of Human Jejunal Smooth Muscle Cell Electrophysiology
Authors: Ai Weiwei , Nickerson David
Published: September 2021

The Poh et al. (2012) paper describes the first biophysically based computational model of human jejunal smooth muscle cell (hJSMC) electrophysiology. The ionic currents are described by either a traditional Hodgkin-Huxley (HH) formalism or a deterministic multi-state Markov (MM) formalism. We create a modularized CellML implementation of the model, which is able to reproduce clamping behaviours of individual currents and whole cell action potential traces. In addition, some inconsistencies have been uncovered and discussed in this paper. EDITOR'S NOTE (v2): A typographical correction in the reproducibility report was made. (v3): This Abstract was appended with a note on changes made to versions.

Published: September 2021

Protease is an important industrial enzyme and salt tolerant protease in which has desirable properties that could enhance its uses not only in industries, but also in agriculture and environmental. Marine organisms usually harbour halophilic microorganisms which produce salt tolerant protease.  In this study, salt tolerant protease producing bacteria from marine sponge were isolated and screened on skim milk marine agar supplemented with different NaCl concentrations (1.5 % w/v). Out of 11 isolates, 8 isolates (S1-1, S1-2, S1-3, S2-1, S2-3, S2-4, S2-5 and S2-6) showed clearing zones with ability to digest casein on the skim milk agar. Morphologically, these strains are gram negative bacilli which grow in yellow colonies and were found to be catalase-positive but oxidase-negative. They are also non-lactose fermenter that produce gelatinase but not α-amylase. The ribosomal 16S rRNA sequencing was used to identify each isolate (Acc. number of S1-1 for MT645770, S1-2 for MT645 771, S1-3 for MT645 772, S2-1 MT645 773, S2-3 MT645 774, S2-4 MT645 775, S2-5 MT645 776 and S2-6 MT645 7767). The 16S rRNA sequences showed that these isolates were highly similar to Stenotrophomonas maltophilia (S2-6, 99.87%) and to a related strain Pseudomonas hibiscicola (S1-1, S1-2, S1-3, S2-1, S2-3, S2-4, S2-5   (97.16-99.9 %). Further proteolytic studies were carried out using skim milk agar with 1.0 %, 2.0 %, 3.0 % and 4.o % (w/v) of NaCl concentrations. All isolates were able to hydrolyze casein which produced clear zones surrounding each colony at 1.0 % and 2.0 % (w/v) salt. However, only isolate S1-5 and S2-6 showed proteolytic activities at 3.0 % (w/v) salt but none of them at 4.0 % (w/v). The ability of these isolates to produce protease which active at higher salt may indicate their potential to be the sources for enzyme with useful properties.
