Acceptable Image Quality

In the course of work on the master's thesis the analysis of daytime and night-time devices was carried out. The analysis showed that devices based on CCD-matrixes prevail in this segment, but the devices of this type cannot be fully called night devices, because the sensitivity of the matrixes used in their designs does not allow to observe without illumination at natural night illumination of 10-3 lux. It is known that IR illumination is a strong unmasking factor.EOS can provide acceptable image quality in natural nightlight. But their use in day-night devices has limitations. Under prolonged exposure to high light, the photocathode of EOS quickly becomes unusable, so when developing a day-night device must provide EOS protection from daylight. Thus it was decided to use CMOS-matrix as an image receiver in the night channel. This, in turn, solves several problems at once. When using the photoreceiver there is no need for mechanical switching between the channels, as there is no danger of light. Also the spectral range of sensitivity of CMOS-matrixes is much more various than that of CCD and EOS that allows to pick up an optimum range of frequencies and to refuse illumination at normal night illumination. In this article a comparison of the calculated range of detection of the device on the basis of EOS of 3 generation with the device in which as the image receiver CMOS-matrix is used.

The context of this paper surrounds my Master’s thesis which was written in 2010 related to recovering crack cocaine addicted mothers who had lost custody of their children. Every qualitative thesis has a story attached to it—an impetus for engaging in the research. When the research combines sensitive topics and the research mirrors the experience of the researcher, decisions must be made considering the research processes and methods. This paper explores the reflexive processes that were employed in the 10 months preceding taking my first thesis course. Using the preface of my reflexive journal as data, three themes arose from subsequent coding with qualitative data analysis software: liminality, the wrestle, and the third space. The resultant discussion of the three themes highlights my journey into the depths of reflexivity and back again as I journeyed into and through the spaces of liminality.

The paper presents the results of a study of variations in ionospheric parameters and local magnetic constant before, during, and after the Вachat earthquake, which occurred on June 18, 2013 at 23:02 UT (June 19, 2013 at 06:02 LT) with a magnitude 5.3–5.6 and epicenter coordinates 54.29° N, 86.17° E. We have used data from IPGG SB RAS and TSU ionospheric stations and INTERMAGNET geomagnetic observatories. We have established that in the period preceding the earthquake there was a rather sharp increase in the magnetic moment, and in the subsequent period there was an equally sharp decrease in the magnetic moment. It is noted that the analysis of the daily average values of the local magnetic constant is the most promising for searching for geomagnetic precursors of earthquakes. We have found a low strong sporadic layer Es for two days before the event, the like of which was not observed for 15 days before and 15 days after the event. In addition, on the days preceding the shock, the background values of the F2-layer critical frequency were larger by more than 20 % at the local pre-event hours. On the second day after the earthquake, there appeared a night-time region of low values (about 14 %), which persisted until the morning of the third day.

Based on the author's Master's thesis at the University of Helsinki in 2005, this article traces the reaction and response by the management of the Finnish alcohol monopoly Oy Alko Ab to the process of European economic integration between 1988 and 1994. The data for the study consist of archive materials, protocols and memoirs, earlier research and literature as well as interviews with key figures involved in the process. A distinction is made between four different periods in the management's reactions between 1988–1994. In the first period 1988–1989, the Alko management began to realise that European integration might have an impact on the company's operation. During the second period 1990–1991, there was a growing recognition that integration would affect the company in a major way and that it would be losing its import and export monopoly. At the same time, the Alko management began taking steps to strengthen the company's competitiveness and organisation. During the third period, from February 1992 to August 1992, the Alko management realised that the company's production and wholesale monopoly might also be under threat. They decided to fight to retain the company's three remaining monopoly rights and did so over the next six months until 25 August 1992, when the battle was limited to the monopoly of off-premise retail sales of alcoholic beverages. In the fourth period from August 1992 to May 1994, the Alko management moved to shore up the company's competitiveness and prepare for the eventuality of the company possibly losing its retail monopoly.

AbstractSince the Second World War, the standard night-time illumination in RN submarine control rooms and adjacent spaces has been red lighting, because of its perceived advantage in dark adaption. Red light is, however, unpopular and has been shown to be detrimental to the performance of other control room tasks. In recent years evidence has emerged from the United States and other Navies that the advantage of red lighting over white lighting in terms of dark adaptation is insignificant at very low intensities. In this paper the research literature is reviewed and the findings related to current lighting practice in RN submarines. At the low levels of control room night illumination, there is minimal practical difference in the time taken for the periscope operator to dark adapt between red and white lighting. In view of the benefits to morale and performance offered by low level white lighting, it should replace red lighting for night use in submarine control rooms.

The following work is focused on the theoretical investigation, about the development of opportunities for linking the reality of caregiving, with its emotional and relational consequences, and a way of relating to one's own experience, mindfulness, aimed at eliminating automatic modes of reaction, guided by preconceptions, categorizations and routines, to act responses oriented to the present, aware and non-judgmental. This is an excerpt from the Master's thesis in Science of the Mind of V. De Rosa, developed during the period of internship at the ASO of Alessandria (SSA of Psychology), and advanced in collaboration with the Psychologist Tutor, Dr. P. Valorio, and the supervisor, Prof. G.C. Geminiani, Professor of Clinical Neuropsychology at the Department of Psychology, University of Turin. In particular, in the first chapter there will be a review of the literature on caregivers, relational modes and responses, often stress, that are established during a period of life which is often accompanied by a sense of overwhelm and uncertainty for the future. In the second chapter, however, we will delve into the studies on mindfulness, its history, its developments and the constant progress of research; we will see how more and more branches of psychology, social sciences and neuroscience are approaching the study of its effectiveness with curiosity. Finally, in the third chapter, we will discuss the proposal of the inclusion of mindfulness elements in the path of psychological support to caregivers. This experiential approach has numerous potentials and applications, and more and more are being proposed. The area of interest in this work is the mindful approach to the reality of life of family caregivers for people with physical, motor or mental deficits that require daily assistance. We will therefore explore various aspects related to both caregiver engagement and the applicability of mindfulness in this area.

The third-order nonlinearity of a novel ET[bis(ethylenedithio)-tetrathiafulvalene] complex (ET ⋅ BF3) has been measured by using the Z-scan technique with a laser pulse width of 30 ps at 1064 nm. The third-order nonlinear refractive index (n2), nonlinear absorption coefficient (β) and nonlinear susceptibilities (χ(3)) of a sample acetonitrile solution are 3.5 × 10-11 esu, 1.65 cm/GW and 5.4 × 10-12 esu, respectively. The nonresonant second-order hyperpolarizability (γ) for the molecule has been estimated to be 2.77 × 10-30 esu. The two merit factors for all-optical switching are W ≫ 1 and T = 1.49, respectively.

Heat Loads

Urban infill can lead to increased urban air and surface temperatures. Landscape elements (LEs) which can maintain cooler surface temperatures also reduce night-time re-emission of heat; however, reflected solar radiation (albedo) from these LEs during the day potentially increases heat loads on nearby objects, pedestrians or buildings. Albedo is traditionally measured using two pyranometers, however their expense can be prohibitive for researchers and landscape professionals. A low cost albedometer was developed consisting of a pair of black- and white-painted temperature sensors (Thermochron® iButtons). The albedos of 14 LEs typically found in suburban landscapes in Perth, Western Australia, were measured. Three approaches were tested: The first two used white-painted polystyrene (WPP) as a reference (one taking view factors into account, and one ignoring the albedo of the background material), whilst the third approach used upwards-facing iButtons as a reference, similar to conventional pyranometer methods. The WPP approaches controlled for weather effects, providing a consistent albedo over a longer daytime period than recommended by the standard ASTM-E1918-16. Measured albedos were similar to literature values. This instrument could be used as an alternative to more expensive pyranometers and could assist landscape professionals to design for, and manage, urban heat.

Insight Into

N-(2-nitrobenzalidene)-2,4-dimethylaniline (1) and N-(3-nitrobenzalidene)-2,4-dimethylaniline (2) have been synthesized and characterized by X-ray diffraction analysis. Linear optical characteristics have been evaluated theoretically using the configuration interaction (CI) method. The maximum one-photon absorption (OPA) wavelengths of the studied compounds are shorter than 450 nm, giving rise to good optical transparency in the visible and near IR regions. To provide an insight into the third-order nonlinear optical (NLO) behavior of the title molecules, both dispersion-free (static) and frequency-dependent (dynamic) linear polarizabilities (α) and second hyperpolarizabilities (γ) at λ = 825 - 1125 nm and 1050 - 1600 nm wavelength ranges have been computed using the time-dependent Hartree-Fock (TDHF) method. The ab initio computational results on (hyper)polarizabilities reveal that both compounds exhibit second hyperpolarizabilities with non-zero values, implying microscopic third-order NLO behavior.
