THE USAGE OF POSITAL CANOPEN AGS15 INCLINOMETERS FOR DIAGNOSTIC MONITORING OF SLENDER STRUCTURES

Abstract

This paper concerns the possibility of using AGS15 capacitive inclinometers in the geodetic monitoring of slender structures. The basics of geometric monitoring have been introduced, and the features of inclinometers that can be used in these studies have been described. Main expectations towards them have been formulated. Three tests were conducted: (1) a few days' stability test of readings, (2) the test of inclinations controlled tachimetrically and (3) continuous survey of a physical object. It has been found that in order to obtain satisfactory results it is necessary to correct the readings due to the drift and the effect of temperature. The works conducted as part of described project work are not capable of identifying those indicators. To achieve them there were designed the system that support the acquisition and processing of the measurement and also the collection and transmission of results. In the conclusions authors stated that inclinometers AGS15 can be suitable for monitoring, but the works aimed at improving their performance should be undertaken.

Using tests and models to assess antidepressant-like activity in rodents

Abstract

In today's world, depression is one of the more prevalent forms of mental illness. According to WHO, about 10%-30% of all women and 7%-15% of all men are afflicted by depression at least once in their life-times. Today, depression is assessed to be affecting 350 million people. Regarding this issue, an important challenge for current psychopharmacology is to develop new, more effective pharmacotherapy and to understand the mechanism of action of known antidepressants. Furthermore, there is the necessity to improve the effectiveness of anti-depression treatment by way of bringing about an understanding of the neurobiology of this illness. In achieving these objectives, animal models of depression can be useful. Yet, presently, all available animal models of depression rely on two principles: the actions of known antidepressants or the responses to stress. In this paper, we present an overview of the most widely used animal tests and models that are employed in assessing antidepressant-like activity in rodents. These include amphetamine potentiation, reversal of reserpine action, the forced swimming test, the tail suspension test, learned helplessness, chronic mild stress and social defeat stress. Moreover, the advantages and major drawbacks of each model are also discussed.

Digitizing Dunhuang Cultural Heritage: A User Evaluation of Mogao Cave Panorama Digital Library

. Figure 1 Homepage of the Mogao Cave Panorama DL© of Dunhuang Research Academy. This study focuses on evaluating the Mogao Cave Panorama Digital Library from the end-user point of view. Four groups of end-users were recruited, based on their professions, to conduct usability tests with nine information seeking tasks designed specifically for the Dunhuang heritage. Findings of this study will help reveal how users interact with the Panorama DL. User friendly and problematic areas will be identified, based on which suggestions can be made for designers and

Usability Evaluation of E-Dunhuang Cultural Heritage Digital Library

knowledge, e-Dunhuang has not been systematically evaluated from a user’s perspective. User experience, with its emphasis on human perception and user–system interactions, is considered a vital aspect of digital library evaluation. Through the process of interacting with the system, users’ awareness, preferences, emotions, and psychological behaviors can be revealed (Kuhlthau, 1991; ISO, 2009 ). Cognizant of this interactive process, this study conducted a user evaluation of e-Dunhuang through usability tests and in-depth interviews. Results will not only be instructive

Reliability and Factorial Validity of Non-Specific and Tennis-Specific Pre-Planned Agility Tests; Preliminary Analysis

testing tennis-specific agility, we suggest using tests of short duration (less than 10 s). Longer test duration will result in higher anaerobic-lactate metabolic demands, making the agility testing questionable. Namely, it is possible that advanced lactate endurance impacts testing results, which should be avoided if the aim is to test agility performance. Different agility performances observed in this study were highly correlated. It led us to conclude that different types of movement patterns could be used in the agility testing of tennis players. According to our

Determination Of The Minimum Ignition Energy On Different Devices

Abstract

This article focuses on determination of the minimum ignition energy of dust. For the measurement of the minimum ignition energy of dust are available device from different manufacturers. In this article, the comparison device from three manufacturers - Chilworth, Kühner and Anko are executed. For the experimental measurement of the minimum minimum ignition energy was chosen 5 dust samples so that they are represented sample of organic dust, synthetic organic dust and coal dust. The article briefly introduces each apparatus for determining the minimum ignition energy and there is a comparison of the results obtained with individual devices. Finally, it is an assessment the results obtained and used test equipment.

Evaluation of Generalized Variance Functions in the Analysis of Complex Survey Data

Abstract

Two sets of diagnostics are presented to evaluate the properties of generalized variance functions (GVFs) for a given sample survey. The first set uses test statistics for the coefficients of multiple regression forms of GVF models. The second set uses smoothed estimators of the mean squared error (MSE) of GVF-based variance estimators. The smooth version of the MSE estimator can provide a useful measure of the performance of a GVF estimator, relative to the variance of a standard design-based variance estimator. Some of the proposed methods are applied to sample data from the Current Employment Statistics survey.

FPGA Implementation of Multi-scale Pedestrian Detection in Thermal Images

Abstract

In this paper an embedded vision system for human silhouette detection in thermal images is presented. As the computing platform a reprogrammable device (FPGA – Field Programmable Gate Array) is used. The detection algorithm is based on a sliding window approach, which content is compared with a probabilistic template. Moreover, detection is four scales in supported. On the used test database, the proposed method obtained 97% accuracy, with average one false detection per frame. Due to the used parallelization and pipelining real-time processing for 720 × 480 @ 50 fps and 1280 × 720 @ 50 fps video streams was achieved. The system has been practically verified in a test setup with a thermal camera.

The Art Of Interpretation – Chances And Risks On Interpretation In The Field Of Mobile Testing

Abstract

Carrying out a usability test is a demanding process per se. Mobile tests raise this claim because they are subject to real usage conditions and therefore unforeseeable factors. On the one hand there are the technical factors like tools, software and laboratory equipment, but on the other hand there are the human beeings with their knowledge and decision-making. They are taking the selection of tools, methods and data, and they decide in every situation of the process of testing. Using a mobile eye-tracking test, the authors will explain where the sources for interpretation are and when misinterpretation become an error. Technology philosophical considerations on interpretation and hermeneutics have to support the recognition of the potential of interpretation. As a result, misinterpretation can be minimized.
