Engine Fuel Consumption Modelling Using Prediction Error Identification and On-Road Data

Engine modelling is an important step in predicting the fuel consumption of a vehicle. Existing methods in the literature require dedicated tests on a test track or on a chassis dynamometer or they require measurements from several days of vehicle operation. This article proposes a new method to model fuel flow rate of a diesel engine and a compressed gas engine using prediction error identification and on-road data collection. The model inputs are the engine torque and speed. The on-road vehicle data was collected during normal transport operations. The identification data set was approximately 99% shorter than the baseline method. The proposed method is applicable for other types of vehicles, including electric vehicles. The identified engine models have less than 1.3% mean error and 2.5% RMS error.
Uttal av S2-finska med fokus på svenskspråkiga talare

I undersokningen analyseras 11 infoddliknande S2-talares uttal av finska. Sex av talarna har finlandssvenska som S1, fem av talarna har sverigesvenska, tyska, franska, ryska resp. spanska som S1. Talarnas uttal undersoktes dels genom ett test med finsksprakiga lyssnare (n=93), dels genom att S2-talarnas uttal jamfordes akustiskt med uttalet hos talare med finska som S1. Vidare jamfordes de finlandssvenska talarnas uttal av finska och svenska. Resultaten visar att finlandssvenska talare skiljer sig som grupp fran infodda finsksprakiga talare och fran talare med ett annat S1 an finlandssvenska. De flesta finlandssvenskar brot mycket svagt. Stavelselangderna och intonationen i langa ord orsakade mest problem for S2-talarna. Generellt hade lyssnarna svart att identifiera talarnas forstasprak, t.ex. finlandssvenska talare foreslogs oftast ha estniska som S1. Det fanns ett tydligt samband mellan startaldern for inlarningen av finska och graden av upplevd infoddlikhet, men ocksa anvandningsgraden av finska och individuell inlarningsformaga verkade vara viktiga forklaringsgrunder till skillnaderna mellan talarna. Nyckelord: finska, finlandssvenska, S2-uttal, tvasprakighet, uttalsinlarning Tutkimuksessa analysoidaan 11 syntyperaisen kaltaisen S2-puhujan suomen aantamista. Kuudella puhujista aidinkieli on suomenruotsi, viidella puhujalla ruotsinruotsi, saksa, ranska, venaja tai espanja. Puhujien aantamista tutkittiin havaintokokeessa (n=93 suomalaista kuulijaa) seka akustisesti vertaamalla puhujien aantamista suomalaisiin puhujiin. Lisaksi verrattiin suomenruotsalaisten puhujien suomen ja ruotsin aantamista. Tulokset osoittavat, etta suomenruotsalaiset puhujat eroavat ryhmana suomalaisista ja taman tutkimuksen muista S2-puhujista. Useimmat suomenruotsalaiset mursivat hyvin heikosti. Tavukestot ja intonaatio pitkissa sanoissa aiheuttivat eniten ongelmia S2-puhujille. Yleisesti ottaen kuulijat eivat tunnistaneet kovin hyvin puhujien lahtokielta, esim. suomenruotsalaisten lahtokielen arveltiin useimmiten olevan viro. Suomen oppimisen aloitusialla ja syntyperaisen kaltaisuudella oli vahva yhteys, mutta myos suomen kielen kayton maara tuntui selittavan monia puhujakohtaisia eroja.

High-Temperature Oxidation Resistance and Tribological Properties of Al2O3/ta-C Coating

The focus is on the oxidation resistance and tribological performance of ta-C and Al2O3/ta-C coatings. The wear tests were carried out on the ball on disc tribometer at room (25 °C) and high (400, 450 and 500 °C) temperatures in ambient air with Si3N4 balls as counterbodies. Scanning electron microscopy and Raman spectroscopy were used to analyze the surface morphology and chemical bonding, respectively. The Al2O3/ta-C coating exhibited better oxidation resistance and tribological performance at elevated temperatures than the ta-C coating. The Raman analysis revealed that a thin alumina layer suppresses structural changes in the ta-C coating at elevated temperatures, thus preserving the sp3 content.
Tukey’s Biweight M-Estimate With Conjugate Gradient Adaptive Learning

We propose a novel M-estimate conjugate gradient (CG) algorithm, termed Tukey’s biweight M-estimate CG (TbMCG), for system identification in impulsive noise environments. In particular, the TbMCG algorithm can achieve a faster convergence while retaining a reduced computational complexity as compared to the recursive least-squares (RLS) algorithm. Specifically, the Tukey’s biweight M-estimate incorporates a constraint into the CG filter to tackle impulsive noise environments. Moreover, the convergence behavior of the TbMCG algorithm is analyzed. Simulation results confirm the excellent performance of the proposed TbMCG algorithm for system identification and active noise control applications.
Chiral Recognition R- and RS- of New Antifungal: Complexation/Solubilization/Dissolution Thermodynamics and Permeability Assay

Novel potential antifungal of 1,2,4-triazole class have been synthesized as pure enantiomer (R-98) and racemic (RS-186). The effect of 2-hydroxypropyl-β-cyclodextrin (CD) on the solubility and permeability of RS-186 and R-98 in terms of chiral recognition was investigated. Phase solubility studies were carried out at 4 temperatures in 0–0.05 M CD concentration range for pH 2.0 and pH 7.4. AL- and AL−-type phase-solubility profiles were obtained for both compounds in pH 2.0 and pH 7.4. The racemic formed more stable complexes with CD as compared to R-isomer. Disclosing of chiral discrimination was facilitated using the approach based on the complex consideration of the derived complexation/solubilization/inherent dissolution thermodynamic functions, including the differential parameters between the racemic compound and R-enantiomer. The differences in the thermodynamic parameters determined by the chirality were discussed in terms of the driving forces of the processes and the main interactions of the compounds with CD in solution. The membrane permeability of both samples in the presence of CD was accessed in order to evaluate the specificity of enantioselective transport through the lipophilic membrane. The solubility/permeability interrelation was disclosed. The investigated compounds were classified as medium permeable in pure buffers and low permeable in the presence of 0.01 M CD. The obtained results can be useful for the design of pharmaceutical products in the form of liquid formulations based on the investigated substances.
Deep Residual Network for Smartwatch-Based User Identification through Complex Hand Movements

Wearable technology has advanced significantly and is now used in various entertainment and business contexts. Authentication methods could be trustworthy, transparent, and non-intrusive to guarantee that users can engage in online communications without consequences. An authentication system on a security framework starts with a process for identifying the user to ensure that the user is permitted. Establishing and verifying an individual’s appearance usually requires a lot of effort. Recent years have seen an increase in the usage of activity-based user identification systems to identify individuals. Despite this, there has not been much research into how complex hand movements can be used to determine the identity of an individual. This research used a one-dimensional residual network with squeeze-and-excitation (SE) configurations called the 1D-ResNet-SE model to investigate hand movements and user identification. According to the findings, the SE modules have enhanced the one-dimensional residual network’s identification ability. As a deep learning model, the proposed methodology is capable of effectively identifying features from the input smartwatch sensor and could be utilized as an end-to-end model to clarify the modeling process. The 1D-ResNet-SE identification model is superior to the other models. Hand movement assessment based on deep learning is an effective technique to identify smartwatch users.
Hardware-Supported Patching of Security Bugs in Hardware IP Blocks

To satisfy various design requirements and application needs, designers integrate multiple intellectual property blocks (IPs) to produce a system on chip (SoC). For improved survivability, designers should be able to patch the SoC to mitigate potential security issues arising from hardware IPs; for increased flexibility, we propose adding programmable hardware-based support for monitoring and bug mitigation. However, it is a challenge to decide how much additional cost a designer should expend up front to deal with unknown, future issues. We propose an approach that guides designers toward maximizing the benefits of adding “patchability” to various IPs in the system, given a target resource overhead. We frame the design problem as an integer quadratic program and show that our approach achieves superior patchability compared to the naïve and baseline approaches for a given cost limit. Experimental results show that when we set a cost limit of 2% field-programmable gate array adaptive logic module usage, our solution can generate a viable patching infrastructure with six patching blocks offering patches for seven different services in our case study.
Cellulosic graphene: growth, characterization, and fabrication toward ambient humidity sensing

ABSTRACT Monitoring environmental humidity using a sensitive, cost-effective device is a contemporary challenge. Considering various sensing materials, graphene has functioned as a best-suitable material for humidity sensing because of its favorable characteristics, for example, large reactive surface area (highly sensitive), better electrical conductivity (fast response of water adsorption), etc. A straightforward and bio-acceptable approach to growing multilayer graphene was formed by the thermal exfoliation process of cellulosic materials. The crystallite size, inter-layer distance, number of layers, crystalline defects, and crystalline planes orientation for synthesized cellulosic-graphene materials were characterized from X-ray diffraction (XRD) analysis, Raman spectroscopy, and High-resolution transmission electron microscopy (HRTEM). Additionally, the elemental analysis was provided by Energy-dispersive X-ray (EDX) spectroscopy. A market-ready product on humidity sensor was fabricated and studied the different parameters associated with sensing mechanism, for example, hysteresis effect with different temperature, effect on impedance with relative humidity, sensitivity, etc. The fabricated device’s better response time and stability may be observed with commercially available humidity sensors (HIH5030 and DHT11H).
Effects of Vitamin D on Fertility, Pregnancy and Polycystic Ovary Syndrome—A Review

Polycystic ovary syndrome (PCOS) is one of the most common endocrine reproductive disorders in women. Vitamin D deficiency is also quite common in this condition. The degree of vitamin D deficiency correlates with the severity of PCOS. Both male and female vitamin D levels play a role in fertility and affect the outcomes of in vitro fertilization (IVF). Moreover, fertility and IVF indicators are improved by vitamin D not only in healthy women but in those diagnosed with PCOS. Both vitamin D deficiency and PCOS increase pregnancy-related complications. Vitamin D supplementation and optimal vitamin D levels decrease both maternal and fetal risk for complications and adverse events. Furthermore, vitamin D supplementation may ameliorate or even prevent pregnancy-related reversible bone loss in mothers. This review emphasizes the roles of vitamin D deficiency and vitamin D supplementation and their correlation with PCOS regarding reproductive health.
Fabrication of micro-structures using non-planar lithography (NPL)

The authors present specific nonplanar lithographic (NPL) techniques for use in fabricating both monolithic micromachines and microcomponents for use in larger systems. The emphasis is on the use of numerically controlled E-beam-based lithography, with the resist exposed over nonplanar surfaces. Previously, nonplanar, optical-mask-based approaches have been used to fabricate devices such as wobble motor rotors, but with less success than the NPL techniques due to depth-of-field problems. The specific focus is on etching cylindrically shaped metal structures which are either (1) homogeneous or (2) layered by successive deposition, masking, and etching. Structures on the order of 80 to 500 microns in diameter have been constructed of either solid metals or sputtered thin metallic layers on quartz shafts. A number of either deep or shallow patterns have been fabricated on and through the structures, with promising results. Examples include helices, longitudinal lines, holes, notches, flexures, barbs, alphanumeric characters, and electrostatic field emitting patterns for use in wobble motors. Efforts are now proceeding toward generating complete systems, including transducers and actuators for industrial and medical applications. <<ETX>>
Anthropomorphic Robotic Eyes: Structural Design and Non-Verbal Communication Effectiveness

This paper shows the structure of a mechanical system with 9 DOFs for driving robot eyes, as well as the system’s ability to produce facial expressions. It consists of three subsystems which enable the motion of the eyeballs, eyelids, and eyebrows independently to the rest of the face. Due to its structure, the mechanical system of the eyeballs is able to reproduce all of the motions human eyes are capable of, which is an important condition for the realization of binocular function of the artificial robot eyes, as well as stereovision. From a kinematic standpoint, the mechanical systems of the eyeballs, eyelids, and eyebrows are highly capable of generating the movements of the human eye. The structure of a control system is proposed with the goal of realizing the desired motion of the output links of the mechanical systems. The success of the mechanical system is also rated on how well it enables the robot to generate non-verbal emotional content, which is why an experiment was conducted. Due to this, the face of the human-like robot MARKO was used, covered with a face mask to aid in focusing the participants on the eye region. The participants evaluated the efficiency of the robot’s non-verbal communication, with certain emotions achieving a high rate of recognition.
MOF/Polymer Mixed-Matrix Membranes Preparation: Effect of Main Synthesis Parameters on CO2/CH4 Separation Performance

Design and preparation of mixed-matrix membranes (MMMs) with minimum defects and high performance for desired gas separations is still challenging as it depends on a variety of MMM synthesis parameters. In this study, 6FDA-DAM:DABA based MMMs using MOF-808 as filler were prepared to examine the impact of multiple variables on the preparation process of MMMs, including variation in polymer concentration, filler loading, volume of solution cast per membrane area, solvent type used and solvent evaporation rate, and to identify their impact on the CO2/CH4 separation performance of these membranes. Solvent evaporation rate proved to be the most critical synthesis parameter, directly influencing the performance and visual appearance of the membranes. Although less dominantly influencing the MMM performance, polymer concentration and solution volume also had an important role via control over the casting solution viscosity, particle agglomeration, and particle settling rate. Among all solvents studied, MMMs prepared with chloroform led to the best performance for this polymer-filler system. Chloroform-based MMMs containing 10 and 30 wt. % MOF-808 showed 73% and 62% increase in CO2 permeability, respectively, without a decrease in separation factor compared to unfilled membranes. The results indicate that enhanced gas separation performance of MMMs strongly depends on the cumulative effect of various synthesis parameters rather than individual impact, thus requiring a system-specific design and optimization.
Problems And Diffculties Encountered By EFL University Students In Using Adjective Intensifiers

A B S T R A C T Adjective intensifiers play an important role in the process of communication in conveying the attitude of the speaker or writer. They are used to focus the reader’s attention as well as to enhance the meaning of adjectives in their writing. The main problem is that English foreign language learners lack the ability to use these intensifiers in relevant register. Also, these intensifiers may perform syntactic and semantic functions and it may overlap and cause ambiguity. This study aims at highlighting the importance of using these intensifiers in written discourse. This study hypothesizes the following: 1. English foreign language learners use adjective intensifiers in their writing. 2. English foreign language learner’s vocabulary is insufficient, and thus they try to use the intensifiers in order to hide their lexical insufficiency. 3. Misuse of intensifiers may lead to semantic or pragmatic misunderstanding and affects negatively on communication. 4. The grammatical proficiency of English foreign language learners does not confirm the appropriate use of intensifiers in written production. This work is limited to the fourth-year students in translation department, college of Arts, Tikrit University. The researcher takes the following procedures: 1. Constructing T-Test. 2. Dividing the test into: a Pre-Test, and a post test. 3. Calculating the mean score statistically in both of the two tests. 4. The researcher discusses the results of both test in order to prove the hypotheses. In this study, the researcher adopts Quirk et al. (1999) model concerning the intensifiers.

THE TACTILE PERCEPTION EVALUATION OF WOOD SURFACE WITH DIFFERENT ROUGHNESS AND SHAPES: A STUDY USING GALVANIC SKIN RESPONSE

By adopting the methods of PAD subjective emotion measurement and galvanic skin response physiological measurement, this study explores the differences in people's tactile perception evaluation of the surfaces of beech materialswith different roughness and shapes. The results show that females prefer beech samples with arc shapes, while males prefer thesamples with rectangle shapes; participants' emotional stability under a higher emotional arousal level can to a certain extentbe maintained due to the beech materials with arc shapes. The tactile perception of males for beech materials has a greater range of emotional arousal than that of females, but the arousal speed of males' emotions is lower than that of females' emotions. Moreover, a better tactile perception experience can be created for participants when theroughness of beech materials is limited within a certain range of conditions, and acertain sense of "anxiousness" will be brought to participants if the surface of beech materials is too rough.
Living with robots: Ethical tradeoffs in eldercare

We discuss some of the research and ideas for developing robot carers and Companions for people with aging brains. We speculate a little about a near-future when it may be possible to keep people at home for longer in the almost exclusive care of robots and smart homes. We examine the benefits of robot care and Companionship and at the same time raise key ethical questions and concerns. We point to a series of trade-offs between the unethical and the beneficial that must be considered before robot care/Companionship becomes commonplace.
A fully depleted lean-channel transistor (DELTA)-a novel vertical ultra thin SOI MOSFET

A fully depleted lean channel transistor (DELTA) having a gate structure and vertical ultrathin SOI (silicon-on-insulator) structure with selective field oxide is reported. In the deep submicron region, selective oxidation is useful for achieving SOI isolation. It provides a high-quality crystal and a Si-SiO/sub 2/ interface as good as those of conventional bulk single-crystal devices. Using experiments and simulation, it was shown that the gate structure of DELTA has effective channel controllability and its vertical ultrathin (<0.2- mu m) SOI structure provides superior device characteristics, e.g. the reduction of short channel effects, minimized subthreshold swing, and high transconductance. The DELTA layout is consistent with the conventional ULSI circuit layout. Thus, DELTA offers both consistency with conventional MOSFETs and good scalability As a 3-D device. As a result, DELTA provides a promising approach for MOSFET structures of less than 0.1 mu m in size. <<ETX>>
Projections régionalisées de la hausse du niveau marin dans les territoires français d'outremer

Au cours des prochaines décennies, l'élévation du niveau des mers devrait contribuer à aggraver les effets des épisodes de submersion affectant le littoral français. Dans cette perspective, l'hypothèse d'une hausse globale du niveau marin de 60 cm à l'horizon 2100 a été adoptée dans la réglementation nationale relative au risque de submersion marine en 2011. En s'appuyant sur les projections établies par le GIEC en 2013, la présente étude montre que cette hypothèse est aujourd'hui sous-estimée. Par ailleurs, les variations du niveau marin ne sont pas uniformes sur l'ensemble du globe. Notamment, les départements et collectivités d'outremer (DOM-COM), dispersés à travers les océans, seront défavorablement affectés par cette variabilité régionale. Dans le "scénario du pire" intéressant plus particulièrement les pouvoirs publics, la hausse du niveau marin d'ici 2100 demeurerait limitée à 100 cm sur la façade Atlantique de la métropole, mais serait proche de 120 cm à Mayotte ou La Réunion. Sur la base de ce double constat, il est recommandé de mettre à jour l'hypothèse de travail retenue dans la réglementation et d'en augmenter la valeur de manière à refléter les plus récents travaux du GIEC. Considérant que les territoires ultramarins sont à la fois plus sensibles au risque de submersion marine et plus exposés à la hausse du niveau marin que la métropole, il est aussi proposé d'adopter des hypothèses de travail régionalisées.
