Self-alignment for microparts assembly using water surface tension

Alignment of microparts is a very important task in the assembly of microsystems. In conventional alignment, servomechanisms are used. However, in general, the servomechanisms are not only too large to align microparts but also complex and expensive. For overcoming these problems, a self-alignment method using liquid surface tension is proposed in this paper. The surface of the used microparts is divided into two kinds of areas: the wettability of one area is higher than that of the other. Using the microparts, the self-alignment is realized as follows: (1) a droplet of liquid is put on high wettability surface area of the first part, (2) the second part is put on the first one, (3) the second part is moved by the surface tension of the liquid so that the wettability area pattern of the first part overlaps with that of the second one and the alignment is accomplished. In this paper, the self-alignment characteristics using water as the liquid is examined experimentally. The experiment results prove the average of the final alignment errors becomes less than 10micrometers even if an initial alignment error is 100micrometers .
Regain of strength after firing of concrete

Synopsis The mechanism of regain of strength as observed in work on the glazing of concrete was investigated on fired and unfired industrially made masonry units by methods including DTA, pore size distribution, and determination of the degree of carbonation. Immediate loss of strength after firing is attributed to the dehydration of cement paste gel, and the main factor in the regain of mechanical strength in a fired block is a carbonation process facilitated by a new capillary system created in firing.
A Simple Methodology Based on the Pittsburgh Coal Method for Assessing Specific Explosion Risks in Dust-Generated Explosive Atmospheres: A Case Study from Galicia (NW Spain)

Hazardous explosive atmospheres caused by dust may occur when powdered combustible material is present in an enclosed area. In general, dust explosions take place when high enough concentrations of combustible powdered dust particles are present in the atmosphere with another suitable gaseous medium such as oxygen. Because the manipulation of these substances in industrial activities entails a risk that could have devastating consequences (including serious injuries or loss of life, as well as significant damage in installations), the risk assessment to eliminate or control the risk of explosive atmospheres in the workplace is a challenging task. In European countries the assessment of these risks is evaluated using the ATEX Directives as per European legislation. However, using this legislation to assess the risk of explosion in powder atmospheres presents difficulties due to the variety and complexity of possible explosive atmospheres and the extremely high variety of ignition sources involved. Therefor.
Climatic variation drives loss and restructuring of carbon and nitrogen in boreal forest wildfire

Abstract. The boreal forest landscape covers approximately 10 % of the earth's land area and accounts for almost 30 % of the global annual terrestrial sink of carbon (C). Increased emissions due to climate-change-amplified fire frequency, size, and intensity threaten to remove elements such as C and nitrogen (N) from forest soil and vegetation at rates faster than they accumulate. This may result in large areas within the region becoming a net source of greenhouse gases, creating a positive feedback loop with a changing climate. Meter-scale estimates of area-normalized fire emissions are limited in Eurasian boreal forests, and knowledge of their relation to climate and ecosystem properties is sparse. This study sampled 50 separate Swedish wildfires, which occurred during an extreme fire season in 2018, providing quantitative estimates of C and N loss due to fire along a climate gradient. Mean annual precipitation had strong positive effects on total fuel, which was the strongest driver for increasing C and N losses. Mean annual temperature (MAT) influenced both pre- and postfire organic layer soil bulk density and C : N ratio, which had mixed effects on C and N losses. Significant fire-induced loss of C estimated in the 50 plots was comparable to estimates in similar Eurasian forests but approximately a quarter of those found in typically more intense North American boreal wildfires. N loss was insignificant, though a large amount of fire-affected fuel was converted to a low C : N surface layer of char in proportion to increased MAT. These results reveal large quantitative differences in C and N losses between global regions and their linkage to the broad range of climate conditions within Fennoscandia. A need exists to better incorporate these factors into models to improve estimates of global emissions of C and N due to fire in future climate scenarios. Additionally, this study demonstrated a linkage between climate and the extent of charring of soil fuel and discusses its potential for altering C and N dynamics in postfire recovery.

The study first discusses electronic tax declaration system, and then empirically tests acceptance levels of CPAs by using Structural Equation Modeling. The study employs socio psychological theories to assess individual attitudes and perceptions of technology adoption process of CPAs. Although there are number of studies in international literature on adoption of electronic tax declaration systems, very limited empirical studies exist in Turkish literature.
Application of Operational Risk Assessment Invasion as a Passive Art Form

An operational risk assessment (ORA) is a method performed by a third party to identify whether a company’s procedures are documented or not. Following the method will produce evidence that the targeted step was executed, so ORA’s simply verify compliance to documented procedures by reviewing byproducts of actual activity. A properly performed ORA mitigates “risks of loss resulting from inadequate or failed internal process, people and systems or from external events” (Basel III 2011). This paper describes an approach to bring these abstract concepts to life within a business school setting, allowing students to recognize the benefits and demonstrate the limits of the technique, bringing the concept to practice.

Evidence for a genetic aetiology in reading disability of twins

small seamounts and ridges, interspersed with sills in the east, reflects an eastward change of some combination of tenstonal crack distribution and the volume rate of magma generation: either the thermal anomaly beneath the tension cracks diminished or the cracks themselves narrowed, The two effects may be combined. The eastward sequence mav also represent a time sequence, formed progressively as the Pacific plate moved northwestward, We bave as yet only two indications of age along the Crass-grain: middie Miocene (14 Myr) sills/flows at 138° W, and passible late Eocene (36-40 Myr) for certain Line Islands Cross Trend features'*°°. This age difference along the cross-grain is ~25 Myr and the distance is ~2,000 km, giving an average rate, assuming progression, of ~B em yr! a figure close to the progression rate of the Hawaiian chain.

Actions of Trust and and their Cognitive Motivation

In this paper I offer a systematic account of actions of trust and inquire into their cognitive motivation. I first develop the distinction and relationship between attitudes and actions of trust, and then assess Paul Faulkner's thesis that the Humean model cannot explain the cognitive motivation of some actions of trust under circumstances of uncertainty. While I will accept his diagnosis, I will contend that a weaker version of the Humean model could provide this explanation. My proposal will be an attempt to show why some doxastic characteristics of trust would allow for this analysis. In particular, I will show how the nature of the reliance relation, which constitutes actions of trust, requires that trustors believe in the possibility of accomplishing their intentions by means of the trusted party’s collaboration. I will argue that this means-end belief can cognitively motivate trust even in situations where the trustor is uncertain as to whether the trusted party will prove trustworthy.
Ornithology Status and distribution of the Antillean Broad-winged Hawk ( Buteo platypterus antillarum ) on the island of Grenada

Because raptors usually occur at low densities and occupy large territories, they can be particularly sensitive to habitat degradation and loss. However, the impacts of these environmental changes on Caribbean raptors are not well understood. This is a significant conservation problem, as the restricted area of islands limits the ability of raptors to find alternate habitats when forests are degraded through agriculture, tourism, forestry, or urbanization. We surveyed the status, distribution, and habitat use of one of the resident diurnal raptors, the Antillean Broad-winged Hawk ( Buteo platypterus antillarum ), on the southern Caribbean island of Grenada. We surveyed this raptor species using double-observer point count and road transect surveys in the wet season (June–December 2016) and the dry season (January–May 2017). We detected a total of 262 hawks during the surveys, 70% ( n = 182) in the wet season and 30% ( n = 80) in the dry season. We assessed hawk habitat use based on elevation and land cover using generalized linear models and maximum entropy models and modeled detectability using N -mixture modelling. Our surveys suggest Antillean Broad-winged Hawks are abundant and widely distributed on Grenada. Broad-winged Hawks use both anthropogenically modified and naturally occurring forest, particularly in sites at relatively low elevation, and show no seasonal changes in habitat use.
Ethnobotanical and Pharmacological Study of Aspidosperma nitidum Benth (Apocynaceae) – a Review

Carapanaúba (Aspidosperma nitidum) is a tree up to 25 meters high and 40 to 60cm in diameter, straight and with a striated trunk. It is a very resistant and easy to use plant mainly for making cables and tools. In addition to the use of this species in the timber industry, this plant has many medicinal properties. Among the pharmacological properties are antinociceptive, anti-inflammatory, antimicrobial, antioxidant, acetylcholinesterase inhibitory, gastroprotective, antitumor and antimalarial activities. The metabolites responsible for antinociceptive activity were not found in the investigated literature. For anti-inflammatory activity, possible activities of the compounds lupeol, sistoterol and stigmasterol were found. For antimicrobial activity, alkaloids, steroids, triterpenes and pentacyclics may be involved in the process. Alkaloids may be related to antioxidant activity. Regarding the inhibitory activity of acetylcholinesterase, the carbonyl ester may be responsible for such activity. For gastroprotective and antitumor activity, alkaloids were also found in the literature as possible involved in the process. Regarding antimalarial activity, the substances responsible for the mentioned activity were not found. The present work reviewed the ethnobotanical and pharmacological properties of Aspidosperma nitidum.
Computational Investigation of the Effect of Luminance Contrast on Depth Perception in Physical and Simulated Scenes

ABSTRACTLuminance distribution of a scene results from the complex interaction of physical construction, light, and visual perception from the point of observation. Perceptual studies using computer-generated environments for accurate variable control have been conducted to perform psychophysical experiments to investigate the cause-and-effect relationship between luminance contrast and its effect on depth perception. The effect of luminance contrast on the perceived distance of a visual target in an architectural scene has been identified through perceptual studies utilizing the pictorial environment generated using the related high dynamic range (HDR) imaging digital technologies. In this study, psychophysical experiments were conducted to investigate the effect of luminance contrast on depth perception in physical and computer-simulated scenes. Experimental scenes were generated using the HDR image of a physical model, and through computer simulations of the same physical model on which image-based lig.
Detection for Corn/Weed Images Using Moment Invariants by BPNN Classifier

This study was conducted to discriminate the weed from the corn in a field combined neural network classifier with image processing technology. The corn and weed images were scanned using a colour imaging system. In the first step, an approximate location of the object of interest was determined by minimum enclosing rectangle, in which image processing was done to obtain the binary image. In the second step, the seven invariant moments were extracted from binary images and used as input to the back propagation neural network (BPNN) classifier. The training set was used to construct shape model representing the objects. The detection accuracy was enhanced by adjusting the number of neurons in the network. Experimental results showed that the BPNN classifier achieved overall detection accuracy of 94.52% with 7-28-1.

Research of Core Competence of the Leading International Engineering Constructors

During the last ten years, the international construction market has kept growing. However, not all the international contractors have good performance according to the study of the rankings of international contractors in ENR TOP 225. The core competence analysis model was established according to the theory and research of the competitiveness in international contracting industry. Two methods to determine the core competences of leading international engineering constructor were confirmed. Firstly, the core competences could be found by studying the market performance to research companies’ products, services and core business units. Secondly, the general competences and core competences could be determined according to the enterprises’ resources and capabilities to determine.
CoSe-Co: Sentence Conditioned Generative CommonSense Contextualizer for Language Models

Pre-trained Language Models (PTLMs) have been shown to perform well on natural language reasoning tasks requiring commonsense. Prior work has leveraged structured commonsense present in knowledge graphs (KGs) to assist PTLMs. Some of these methods use KGs as separate static modules which limits knowledge coverage since KGs are finite, sparse, and noisy. Other methods have attempted to obtain generalized and scalable commonsense by training PTLMs on KGs. Since they are trained on symbolic KG phrases, applying them on natural language text during inference leads to input distribution shift. To this end, we propose a task agnostic sentence-conditioned generative CommonSense Contextualizer (CoSe-Co), which is trained to generate contextually relevant commonsense inferences given a natural language input. We devise a method to create semantically related sentence-commonsense pairs to train CoSe-Co. We observe commonsense inferences generated by CoSe-Co contain novel concepts that are relevant to the entire sentence context. We evaluate CoSe-Co on multi-choice QA and open-ended commonsense reasoning tasks on the CSQA, ARC, QASC, and OBQA datasets. CoSe-Co outperforms state-of-the-art methods in both these settings, while being task-agnostic, and performs especially well in low data regimes showing it is more robust and generalises better.
Analysis of V‐slot loaded patch for wide‐band operation

In this article, analysis of V‐slot loaded patch antenna is proposed using equivalent circuit model. Such antenna provides a wide bandwidth which depends inversely on the base width and slot thickness. The proposed results are compared with experimental and simulated results which are in good agreements. Radiation pattern of the proposed antenna is in good agreement with the simulated results. This validates the accuracy of the proposed model. © 2008 Wiley Periodicals, Inc. Microwave Opt Technol Lett 50: 3069–3075, 2008; Published online in Wiley InterScience (www.interscience.wiley.com).

Improving the understanding of N transport in a rural catchment under Atlantic climate conditions from the analysis of the concentration–discharge relationship derived from a high-frequency data set

Abstract. Understanding processes controlling stream nutrient dynamics over time is crucial for implementing effective management strategies to prevent water quality degradation. In this respect, the study of the nutrient concentration–discharge (C–Q) relationship during individual runoff events can be a valuable tool for extrapolating the hydrochemical processes controlling nutrient fluxes in streams. This study investigated nitrogen concentration dynamics during events by analyzing and interpreting the nitrogen C–Q relationship in a small Atlantic (NW Iberian Peninsula) rural catchment. To this end, nitrate (NO3-N) and total Kjeldahl nitrogen (TKN) concentrations were monitored at a high temporal resolution during 102 runoff events over a 6-year period. For each of the selected runoff events, C–Q response was examined visually for the presence and direction of hysteresis loops and classified into three types of responses, namely clockwise, counterclockwise, and no hysteresis. Changes in concentration (ΔC) and the hysteresis direction (ΔR) were used to quantify nitrogen (NO3- and TKN) patterns during the runoff events. The transport mechanisms varied between compounds. The most frequent hysteretic response for NO3- was counterclockwise with enrichment. On the contrary, the main TKN dynamic was enrichment with clockwise hysteresis. Event characteristics, such as rainfall amount, peak discharge (i.e., maximum discharge of the runoff event), and event magnitude relative to the initial baseflow (i.e., the difference between the maximum discharge of the runoff event and the initial baseflow divided by initial baseflow) provided a better explanation for hysteresis direction and magnitude for TKN than antecedent conditions (antecedent precipitation and baseflow at the beginning of the event). For NO3- hysteresis, the role of hydrometeorological conditions was more complex. The NO3- hysteresis magnitude was related to the magnitude of the event relative to the initial baseflow and the time elapsed since a preceding runoff event. These findings could be used as a reference for the development of N mitigation strategy in the region.

Suppression of multiple narrow-band interference using real-time adaptive notch filters

The process of detection of narrow-band interference to a broad-band signal in a noisy environment using adaptive filtering techniques attributable to Kwan and Martin (1989) is further refined by modifying the gradient-search algorithm to reduce hardware complexity. The Kwan and Martin algorithm implies a geometric increase in hardware as the number of interferers increases. The improved method admits to only an arithmetic increase to achieve the similar results. Thus Kwan and Martin filters designed to handle 3 to 10 notches require 12.5% to 124% more hardware than the new filters. Simulations of the new method show it to be robust, functioning well in a variety of practical signal processing applications.
