Traditional research on security and safety has been based on the assumption that a user feels secure and safe when using objectively secure and safe systems and services. The authors investigate factors influencing users’ subjective sense of security, which they call Anshin in Japanese. In this chapter, the authors introduce the concept of Anshin as an emotional trust and its research issues. They also show how to use statistical analysis methods to derive the factors of Anshin and present some results. Results using exploratory factor analysis and structural equation modeling bring us with three factors contributing to Anshin.

Hoc Networks

This chapter introduces opportunistic networks. Such networks support spontaneous interaction between mobile users carrying mobile devices with them. After having been presented with the motivation for this new type of network, the reader will learn the underlying concepts, including an opportunistic network definition. Next, this chapter discusses what makes opportunistic networks different to mobile peer-topeer networks and mobile ad hoc networks; two network types that are closely related. We present a number of applications with a focus on data dissemination. As a sequel to that, the chapter discusses human factors that are important for opportunistic networks, namely privacy preserving techniques and an incentive scheme. The chapter concludes with an overview of future research issues by naming a number of open and unsolved problems.

The purpose of the article is to study and develop theoretical and methodological principles of forensic aviation technical expertise, recommendations for the application of special knowledge in criminal, civil, commercial and administrative proceedings to prevent, detect, investigate and consider by investigators / courts crimes related to violations of regulations legal acts on traffic safety or operation of air transport, as well as improving its methodology, justification and formulation of recommendations for legal evaluation of results and increase the effectiveness of the use of forensic conclusions in the process of proof. The methodological basis of the study are the laws and categories of the theory of knowledge, in particular the provisions of materialist dialectics, which contributed to the understanding of the purpose and objectives, subject, object, research issues in the context of interdependence of achievements and needs of practice. At the same time, the methods of formal logic (analysis, synthesis, deduction, induction, analogy, abstraction) made it possible to understand in more detail the content of the studied questions, the essence of the studied categories and phenomena was clarified by the system-structural method. The Ministry of Justice of Ukraine has created a new type (subtype) of forensic examination: “Aviation Technical” and forensic specialty 10.25 “Investigation of aviation events and incidents”, so the article formulates the basic concepts of forensic aviation technical examination, namely: identifies the main issues, which are decided by forensic aviation technical examination; tasks, subject, object which give the chance to understand essence and the maintenance of expert activity of these researches; the tasks of a specific examination are distinguished from the tasks of other related types of examinations in this area. The process of researching air transport objects is quite complex, diverse and specific. The problems facing the investigation (court) determine the feasibility of creating and developing a theoretical basis for a new type (subtype) of forensic examination: “Aviation Technical” and forensic specialty 10.25 “Investigation of aviation events and incidents”. To solve the tasks and create a coherent system of expert research in air transport, it is necessary to conduct a set of research works to develop a methodological basis for this type (subspecies) of forensic examination.

Diffraction Diagram

A new type of synthetic industrial diamond formed by an explosive shock process has been recently developed by the Du Pont Company. This material consists of a mixture of two basically different forms, as shown in Figure 1: relatively flat and compact aggregates of acicular crystallites, and single crystals in the form of irregular polyhedra with straight edges.Figure 2 is a high magnification micrograph typical for the fibrous aggregates; it shows that they are composed of bundles of crystallites 0.05-0.3 μ long and 0.02 μ. wide. The selected area diffraction diagram (insert in Figure 2) consists of a weak polycrystalline ring pattern and a strong texture pattern with arc reflections. The latter results from crystals having preferred orientation, which shows that in a given particle most fibrils have a similar orientation.

The Ideal

I. IntroductionThermionic electron gun with the Wehnelt grid is popularly used in the electron microscopy and electron beam micro-fabrication. It is well known that this gun could get the ideal brightness caluculated from the Lengumier and Richardson equations under the optimum condition. However, the design and ajustment to the optimum condition is not so easy. The gun has following properties with respect to the Wehnelt bias; (1) The maximum brightness is got only in the optimum bias. (2) In the larger bias than the optimum, the brightness decreases with increasing the bias voltage on account of the space charge effect. (3) In the smaller bias than the optimum, the brightness decreases with bias voltage on account of spreading of the cross over spot due to the aberrations of the electrostatic immersion lens.In the present experiment, a new type electron gun with the electrostatic and electromagnetic lens is designed, and its properties are examined experimentally.

Microstructural Studies

After materials with superconducting temperatures higher than liquid nitrogen have been prepared, more emphasis has been on increasing the current densities (Jc) of high Tc superconductors than finding new materials with higher transition temperatures. Different processing techniques i.e thin films, shock wave processing, neutron radiation etc. have been applied in order to increase Jc. Microstructural studies of compounds thus prepared have shown either a decrease in gram boundaries that act as weak-links or increase in defect structure that act as flux-pinning centers. We have studied shock wave synthesized Tl-Ba-Cu-O and shock wave processed Y-123 superconductors with somewhat different properties compared to those prepared by solid-state reaction. Here we report the defect structures observed in the shock-processed Y-124 superconductors.

Over recent years a new type of electron microscope - the environmental scanning electron microscope (ESEM) - has been developed for the examination of specimen surfaces in the presence of gases. A detailed series of reports on the system has appeared elsewhere. A review summary of the current state and potential of the system is presented here.The gas composition, temperature and pressure can be varied in the specimen chamber of the ESEM. With air, the pressure can be up to one atmosphere (about 1000 mbar). Environments with fully saturated water vapor only at room temperature (20-30 mbar) can be easily maintained whilst liquid water or other solutions, together with uncoated specimens, can be imaged routinely during various applications.

Fringing Fields

Imaging energy filters can add new information to electron microscopic images with respect to energy-axis, so-called electron spectroscopic imaging (ESI). Recently, many good results have been reported using this imaging technique. ESI also allows high-contrast observation of unstained biological samples, becoming a trend of the field of morphology. We manufactured a new type of energy filter as a trial production. This energy filter consists of two magnets, and we call γ-filter since the trajectory of electrons shows ‘γ’-shape inside the filter. We evaluated the new energyγ-filter TEM with the γ-filter.Figure 1 shows schematic view of the electron optics of the γ-type energy filter. For the determination of the electron-optics of the γ-type energy filter, we used the TRIO (Third Order Ion Optics) program which has been developed for the design of high resolution mass spectrometers. The TRIO takes the extended fringing fields (EFF) into consideration. EFF makes it difficult to design magnetic energy filters with magnetic sector fields.

Reading System

The Imaging Plate (IP) is a new type imaging device, which was developed for diagnostic x ray imaging. We have reported that usage of the IP for a TEM has many merits; those are high sensitivity, wide dynamic range, and good linearity. However in the previous report the reading system was prototype drum-type-scanner, and IP was also experimentally made, which phosphor layer was 50μm thick with no protective layer. So special care was needed to handle them, and they were used only to make sure the basic characteristics. In this article we report the result of newly developed reading, printing system and high resolution IP for practical use. We mainly discuss the characteristics of the IP here. (Precise performance concerned with the reader and other system are reported in the other article.)Fig.1 shows the schematic cross section of the IP. The IP consists of three parts; protective layer, phosphor layer and support.
