HOLMES: A Platform for Detecting Malicious Inputs in Secure Collaborative Computation

—Though maliciously secure multiparty computation (SMPC) ensures conﬁdentiality and integrity of the computation from malicious parties, malicious parties can still provide mal-formed inputs. As a result, when using SMPC for collaborative computation, input can be manipulated to perform biasing and poisoning attacks. Parties may defend against many of these attacks by performing statistical tests over one another’s input, before the actual computation. We present HOLMES, a platform for expressing and performing statistical tests securely and efﬁciently. Using HOLMES, parties can perform well-known statistical tests or deﬁne new tests. For efﬁciency, instead of performing such tests naively in SMPC, HOLMES blends together zero-knowledge proofs (ZK) and SMPC protocols, based on the insight that most computation for statistical tests is local to the party who provides the data. High-dimensional tests are critical for detecting malicious inputs but are prohibitively expensive in secure computation. To reduce this cost, HOLMES provides a new secure dimensionality reduction procedure tailored for high-dimensional statistical tests. This new procedure leverages recent development of algebraic pseudorandom functions. Our evaluation shows that, for a variety of statistical tests, HOLMES is 18 × to 40 × more efﬁcient than naively implementing the statistical tests in a generic SMPC framework.
BASE-ISOLATION DESIGN PRACTICE IN JAPAN: INTRODUCTION TO THE POST-KOBE APPROACH

Japan has twenty years of experience in designing and constructing base-isolated building structures. Construction has increased significantly since the 1995 Hyogoken-Nanbu (Kobe) earthquake, having reached over 150 annual construction projects. Many new developments and refinements have been made in the material, device, design, and construction of these structures. This paper summarises recent design and construction of base-isolated building structures in Japan, including statistical data with respect to the common usage as well as the number of new projects. It is notable that the size, height, and fundamental natural period of new base-isolated buildings increase steadily with time, indicating that base-isolation in Japan is reaching maturity. Base-isolators and dampers commonly adopted in Japan are also introduced, with emphasis on recent design efforts to enlarge the natural period of base-isolated structures and reduce the lateral forces induced in the superstructure. Basic design procedures are presented, including determination of design earthquake forces, modelling of base-isolation layers, modelling of the superstructure, selection of ground motions, time-history analyses, and performance criteria. A mandated peer-review system, unique for design of base-isolated structures, is also noted. Several characteristic issues in the design of base-isolated structures are discussed: Variation of base-isolation material properties, applications to high-rise buildings, effects of vertical ground motions, and response when subjected to near-fault ground motions.
Aplicação dos Conceitos do Lean Thinking em Lavanderias Hospitalares: Uma Revisão Sistemática de Literatura

A fim de identificar as oportunidades de melhoria nos processos que podem ser aplicadas nas lavanderias hospitalares, o estudo teve como objetivo reconhecer os principais problemas, desperdícios, ferramentas, metodologias utilizadas, resultados e dificuldades encontradas nos estudos realizados sobre o lean thinking em lavanderias. Dessa forma, foi reconhecido que o principal desperdício abordado nos estudos é o de processamento em si, que refere-se às atividades que não agregam valor ao produto ou serviço final (OHNO, 1997). A Revisão Sistemática de Literatura apontou que o mapeamento funcional dos processos e o do fluxo de valor são as principais ferramentas para solucionar os problemas. Tendo essas ferramentas como base, foi apresentada como dificuldade nos estudos a mensuração de cada etapa do processo, tendo como solução a padronização do trabalho, que proporcionou a redução de 100% das perdas de roupas em um dos estudos. Assim, os resultados deste trabalho contribuem com a implementação de melhorias em lavanderias, e para estudos futuros. Fitriasari, Haryanto e Yuliansyah (2018) recomendam a identificação da eficiência e de custos dos sistemas de monitoramento e controle de perdas de roupas e esses autores obtiveram um resultado significativo com a padronização.
Experimental Study on Thermal Striping in Mixing Tees With Hot and Cold Water

Thermal striping tests in mixing tees with hot and cold water were conducted for three types of flow conjunctions in order to establish an evaluation method for high-cycle thermal fatigue of piping systems. Two kinds of examinations were planned. The preliminary tests were flow visualization tests carried out using acrylic pipes to obtain flow pattern characteristics and flow temperature fluctuations. The main tests were temperature fluctuation measurement tests carried out using metal pipes to evaluate the unsteady heat transfer coefficient based on measured temperature fluctuations of fluid and pipe wall. This paper reports visualization test results. The flow patterns were visualized by injection of methylene blue and compared with flow analysis results by the k-e turbulence model. Temperature fluctuations of fluid 3mm from the inner pipe wall were measured with C-A thermocouples. Fundamental features such as locations with a large fluctuating temperature, the fluctuating temperature amplitude and its frequency were identified.Copyright © 2002 by ASME
Simulation of intrinsic parameter fluctuations in nano-CMOS devices

As devices are scaled to gate lengths of sub 100 nm the effects of intrinsic parameter fluctuations will become increasingly important.This work presents a systematic simulation study of intrinsic parameter fluctuations, consisting of random dopant fluctations, line edge roughness and oxide thickness fluctuations, in a real 35 nm MOSFET developed by Toshiba. The simulations are calibrated against experimental data for the real device and it is found that discrete random dopants have the greatest impact on both the threshold voltage and leakage current fluctuations with a σVT of 33.2mV and a percentage increase in the average leakage current of 50%. Line edge roughness has the second greatest impact with a σVT of 19mV and percentage increase in the average leakage current of 45.5%. The smallest impact is caused by oxide thickness variations resulting in a σVT of 1.8mV and a 13% increase in the average leakage current. The combined effects of pairs of fluctuations is also studied, showing that these sources of intrinsic parameter fluctuations are statistically independent and a calculated σVT of 39mV is given for all of the sources combined. This value is on par with that reported in literature for the 90 nm technology node.
PRODUCT FAMILY DESIGN WITH GROUPING GENETIC ALGORITHM—A CASE STUDY

ABSTRACT Product family is a result of derivation design, which is constructed to target various niche market segments. However, component variety may also cause over design and resources waste due to deficient preliminary analysis. Modular design to form product platform is, thus, important to enhance resource allocation and promote mass customization. In this study, a mathematic programming is proposed to simultaneously conduct platform and modular design as well as to optimize the number of modules. As to the issue of combinational components allocation, a heuristic grouping genetic algorithm is proposed, where crossover, mutation, and initial population operations is modified for such specific domain. Furthermore, a systematic design approach is developed according to product planning, functional relationships analysis, and physical relationships analysis, in which functional flow chart, interaction matrices, and computer programming are adopted to visualize the design process. Finally, a case design of coffee maker family is illustrated exhaustively.
Trajectories of depression symptoms during the process of deployment in military couples

ABSTRACT Informed by life course theory, we estimated depression symptom trajectories for couples throughout a deployment cycle using data from a longitudinal study of National Guard couples (n= 339). One-third of couples served as a comparison group by participating in data collection after their deployments were canceled. We proposed that 1) service members and partners would display multiple trajectories of depression symptoms that differ as a function of role (i.e., service member or at-home partner) and exposure to deployment; 2) trajectory patterns would be associated with indicators of human capital; 3) service members’ and partners’ depression symptoms would be linked to each other. We found that depressive symptom trajectories varied by exposure to deployment and role, and that higher levels of human capital were mostly associated with lower depressive symptoms, although we did not find support for partner interdependence. Results were considered in the context of life course theory and emotional cycles of deployment.
Crevice volume effect on spark ignition engine efficiency

A set of experiments and a simulation study are completed to quantify the effect of the piston crevice on engine efficiency. The simulation study breaks down the loss mechanisms on brake efficiency at different displacement volumes (300 500 cc) and compression ratios (8-20). Experiments focus on indicated efficiencies for a narrow range of compression ratios (9.2412.57) with different piston crevice volumes. Piston crevice volume is increased in two steps by machining a groove into the piston top land, and is decreased by raising the top ring. Indicated efficiency is measured at various loads (0.4 1.0 bar MAP), speeds (1500, 2000, 2500 rpm), and coolant temperatures (50'C and 80'C). All data points compared in this study are recorded at MBT timing with a relative air-fuel ratio (k) of 1. For the baseline case (CR = 9.24, speed = 2000 rpm, coolant = 80'C), increased crevice volume results in an indicated efficiency degradation of 0.3-0.5%-points per 1000 mm . This absolute decrease corresponds to a 1.2-1.5% relative decrease for a 100% increase in crevice volume; referenced to the control piston crevice modification. Decreasing crevice volume leads to a gain in indicated efficiency of 2.3-3.5%-points per 1000 mm3 , which corresponds to a 6.911. 8% relative increase for a 100% decrease in crevice volume; referenced to the control piston crevice modification. Results of the experimental investigation, when compared across compression ratio, engine speed, and coolant temperature, show that the crevice effect on efficiency is largely independent of these three parameters. Large gains from decreased piston crevice volume prompt renewed discussions on piston top land, top ring, and crown design. Thesis Supervisor: Wai K.

An experimental method to design piezoelectric energy harvesting skin using operating deflection shapes and its application for self-powered operation of a wireless sensor network

This work proposes a more practical way of designing the piezoelectric energy harvesting skin, which facilitates the application of the proposed idea to any practical engineering facilities with vibration. Unlike earlier studies to make use of analytical model for piezoelectric energy harvesting design, this work proposes an experimental method to design a piezoelectric energy harvesting skin using operating deflection shapes of a target mechanical system. This method is more practical in the sense that actual vibration of a target mechanical system can be characterized far better for the piezoelectric energy harvesting design. The key idea is to extract continuous in-plane normal strain values from discrete out-of-plane deformations of a target mechanical system. From multiple strain inflection lines, piezoelectric energy harvesting skin segments are designed to maximize a total power output. It is demonstrated that four piezoelectric energy harvesting skin segments designed by the proposed idea can generate sufficient power from the outdoor condensing unit of an air conditioning for self-powered operation of a wireless sensor network.
Research on optimum cut direction of quartz transducer

Acousto-optic (AO) technology sprang up at the beginning of 1960s, after the naissance of laser. The electro-acoustic transducer is an important part of acousto-optic device (AOD), and quartz is an important crystal for making the transducer due to its good piezoelectric property. In this paper we calculated two kinds of acoustic velocities, non-strengthened acoustic velocities and strengthened acoustic velocities, for three kinds of acoustic modes, one longitudinal wave and two shear waves, in three coordinate planes of the quartz systematically using Christoffel equations. Then electromechanical coupling coefficients of every acoustic mode are calculated and curves of coefficients in three coordinate planes are pictured. Finally we determined the optimum cut direction of longitudinal wave and shear wave respectively. The results of this paper will play a directional role for the research of AOD.
Design of Cylindrical Conformal Array Antenna based on Microstrip Patch Unit

─ Based on microstrip patch antenna, a cylindrical conformal 8×8 array antenna is designed, which uses a T-shaped power divider to realize 64 feed channels. The simulation results show that the peak gain of planar array antenna can reach 24.8dB, while the peak gain of cylindrical conformal antenna decreases by 1.2dB and 1.7dB in phi=0° and phi=90° respectively. And the main beam direction deflects by 0° and 4° respectively. The measurement results show that the performance of the processed object is close to the simulation. After conformal with cylinder, the peak gain is 23.5dB, and the beam deflection is 4°, which verifies the feasibility of the designed cylindrical conformal array antenna. Index Terms ─ Array antenna, conformal, microstrip patch.

Rotary Dryer Control Using a Grey-Box Neural Model Scheme

The application of a Grey-box Neural Model (GNM) in a nonlinear model predictive control scheme (NMPC) of a direct rotary dyer is presented in this work. The GNM, which is based on the combination of phenomenological models and empirical artificial neural network (ANN) models, was properly developed and validated by using experimental fish-meal rotary drying information. The GNM was created by combining the rotary dryer mass and energy balances and a feed forward neural network (FFNN), trained off-line to estimate the drying rate and the volumetric heat transfer coefficient. The GNM results allowed us to obtain the relation between the controlled variable (solid moisture content) and the manipulated variable (gas phase entrance temperature) used in the predictive control strategy. Two NMPC control strategies, one with a fixed extended prediction horizon and another with an extended range prediction horizon, were applied to a simulated industrial fish-meal drying process. The results showed that a correct rotary dryer representation can be obtained by using a GNM approach. Due to the representation capability of the GNM approach, excellent control performances of the NMPCs were observed when the process variables were subject to disturbances. As analyzed in this work, the fixed extended prediction horizon MPC surpassed recognized control methodologies (quadratic dynamic matrix control).
Vizualizace dat jako informační bariéra u nevidomých uživatelů

Purpose – While communicating data in media, science, and education visually, we must consider that a certain percentage of recipients will be limited in their visual perception. The disadvantages of visual perception can be varied. They range from common refractive errors and colour blindness (these can be dealt with simply) to complete loss of visual perception, i.e. blindness. Blindness is still not often addressed in the data visualisation community, despite creating a significant information barrier. Design/Methodology/Approach – The article is conceived as a conceptual one. It brings a synthesis of findings from past work and research on specific topics and presents them through the perspective of a new context – to provide a springboard for further research. Results – The concept paper synthesises the debates and hitherto approaches to breaking down possible visual barriers in the perception of data visualisations, examining the topic in a broader context. At the heart of this examination are questions about meaningful forms and approaches to the design of assistive technologies and their social aspects. The article argues that simple haptisation of visual sources may not be sufficient and that the social aspects of the solution must also be considered. Originality/Value – The concept article deals with a sidelined topic of data visualization debate. Equally important, it serves as a call to action for further research into this crucial issue.
Fabrication of Diamond-Structure Alumina Photonic Crystal with Rectangle Cavity Defect and its Microwave Properties

A diamond-structure alumina photonic crystal with a rectangle cavity defect has been fabricated combining stereolithography (SL) and gel-casting. In transmission spectra a resonance peak of transmission of 70% is observed in the band gap of 10.48Ghz-12.21Ghz, by comparing with the measured result of the perfect structure and theoretical calculations. Experimental results showed that the peak of photonic band gap was caused by the rectangle cavity defect of the diamond structural photonic crystal. The method provides us with a novel approach to fabricate ceramic microwave photonic crystals with point defect.
Single-event phenomena in GaAs devices and circuits

The single-event upset (SEU) characteristics of GaAs devices and circuits are reviewed. GaAs FET-based integrated circuits (ICs) are susceptible to upsets from both cosmic-ray heavy ions and protons trapped in the Earth's radiation belts. The origin of the SEU sensitivity of GaAs ICs is discussed in terms of both device-level and circuit-level considerations. At the device level, efficient charge-enhancement mechanisms through which more charge can be collected than is deposited by the ion have a significant negative impact on the SEU characteristics of GaAs ICs. At the circuit level, different GaAs digital logic topologies exhibit different levels of sensitivity to SEU because of variations in parameters, including logic levels, capacitances, and the degree of gate or peripheral isolation. The operational and SEU characteristics of several different GaAs logic families are discussed. Recent advances in materials and processing that provide possible solutions to the SEU problem are addressed.
Factors Predicting the Frequency of Second Seizures in Patients Presenting to the Emergency Department With Seizures: A Prospective Observational Study

Introduction This study aimed to determine the factors that trigger seizures in patients reporting to our emergency department (ED) with seizures and the factors that affect recurrent seizures during the emergency department stay. Materials and methods This study was designed prospectively and was conducted among patients over the age of 18 years who reported to the ED of the Education and Research Hospital with complaints of epileptic seizure between July 01, 2020 and July 01, 2021. In addition to the sociodemographic information of the patients, the time of admission after the seizure, the medications used, comorbidities, the treatment given in the ED, history of trauma, previous epilepsy diagnosis, time of last seizure, alcohol use in the last 24 hours, insomnia, presence of infective symptoms in the past week, vital parameters, blood tests, and presence of recurrent seizure during hospital follow-up were recorded. Results The median age of the 102 patients included in the statistical analysis was 37 (25%-57%), and 61 (59.8%) were men. Patients who came to the ED with the complaint of seizures were divided into two groups, namely, those who had recurrent seizures and those who did not. When the differences between the groups in terms of various variables were examined, no statistically significant difference was found in the univariate analysis, except for WBC, aspartate aminotransferase (AST), and alanine aminotransferase (ALT) values. The diagnostic value of WBC, AST, and ALT levels in predicting recurrent seizures in emergency follow-up was analyzed using a receiver operating characteristic curve. Conclusion In this study, we could not find a parameter that can predict the probability of recurrent seizures in the ED in patients presenting with epileptic seizures.

Modélisation des anisotropies mécaniques induites par la fissuration du béton

ABSTRACT Concrete cracking is modeled in the general framework of anisotropic damage theory with anelastics strains. The use of anisotropic criteria allows to describe both direct and induced tension cracks that appear at the aggregate—cement paste interfaces; thus damage is represented by two second order tensors for direct and induced tension, respectively, which define the marginal damages. A possible rotation of the cracks is obtained by formulating the criteria flow in the principal axes of effective stresses. Mechanical damage approximation is deduced from marginal damages by using the weakest link theory extended to the cases of non proportional loading. This method, which makes it possible to couple several non coaxial damage tensors, is presented in this paper in a restrained framework including only mechanical cracking causes; nevertheless it can be generalized without difficulties to other cracking causes (chemical damage for example). In finite element context, objectivity of the post peak tensile behavior is ensured thanks to an anisotropic Hillerborgh procedure. The efficiency and relevancy of the model are analyzed through the results of numerical simulations of various structures; these results are compared to experimental data when available.
