In this paper, we propose the sensor and the signal duplicator for the automatic building control. Developed duplicator realizes the sensor data collection apparatus and mimics the measured data and, thus, reduces the construction cost by using logical communication layer. Furthermore, the system supports the open protocols and can be associated with HMI(Human Machine Interface) used on the market. Developed duplicator is proved to be functional within the real environment. Measurement error rate, operating temperature, and operating humidity show very good results by the certified testing apparatus and organization.

This paper presents the performance and problems in analysis method and testing system of Electronic Speckle Pattern Interferometry (ESPI) method, in measuring two - dimensional in-plane displacement. The anyalysis result of measurement by ESPE is quite comparable to that tof measurement by strain gauge method. This implies that the method of ESPE is a very effective tool in non-contact two-dimensional in-plane strain analysis. But there is a controversal point, measurment error. This error is discussed to be affected not by ESPE method itself, but by its analysis scheme of the interference fringe, where the first-order interpolation has been applied to the points of strain measured. In this case, it is turned out that the more errors would be occurred in the large interval of fringe. And so this paper describes a computer method for drawing when the height is available only for some arbitrary collection of points. The method is based on a distance-weighted, last- squares approximation technique with the weight varying with the distance of the data points.

The study tested a hybrid model with constructs drawn from the Technology Acceptance Model (TAM) and Diffusion of Innovation (DOI) theory in order to examine the moderating effect of productivity and relative advantage (RA) on perceived usefulness (PU) vis-à-vis electronic information resources (EIR) adoption in private university libraries in Ogun and Osun States of Nigeria. The descriptive research design was adopted in the study. The population consisted of 61 (55.0%) librarians and 50 (45.0%) library officers (totaling 116—100%) in Babcock University, Bells University, Covenant University, Bowen University, Oduduwa University, and Redeemer's University. Purposive sampling procedure was adopted after which total enumeration was used since the total population is small. The questionnaire was used for data collection. Of the 116 copies of the questionnaire administered, 111 (95.7%) were found usable. The instrument was structured based on a 4-point Likert agreement scale of Strongly Agree, Agree, Disagree, and Strongly Disagree. Data were analyzed using descriptive statistics like tables of frequency counts and percentage. The findings revealed that productivity and relative advantage are significant moderators of perceived usefulness of EIR adoption in private university libraries in Ogun and Osun States, Nigeria.

The aim of this study was to investigate why people voluntarily contribute knowledge to others, primarily strangers, in the electronic network of practice for job examination expected potential competing. This paper is organized as follows. First, we introduce the electronic network of practice which is the knowledge sharing community for job examination, and discuss the key issues for understanding knowledge sharing in these networks on the basis of individual motivations, relational capital, sense of community, and sense of rivalry to develop a research model for this study. To test the proposed research model, we adopted the survey method for data collection, and examined our hypotheses by applying the multiple regression analysis method to the collected data. Our unit of analysis was the individual. The findings of this study show that the intention of knowledge sharing is influenced by the reputation and the enjoy helping as the factors of individual motivations, by the reciprocity as the factor of relational capital, and by a sense of rivalry as a psychological factor. Lastly, contributions of this study and future research opportunities are also discussed.

Due to the acceleration of urbanization and advancements in technology, the importance of information related to indoor spaces has been increasing. Various scanning technologies are being developed to enable versatile utilization of the interior of buildings. In this paper, a system is proposed that utilizes 2D LIDAR for scanning, rotating, and moving LIDAR in the vertical direction to obtain a collection of 2D data, which is then aggregated to acquire 3D indoor spatial information. Finally, algorithms, including error correction, are applied to visualize the indoor structure in three dimensions and generate an output.

With rapid telecommunication development, university libraries began to provide traditional services as well as web-based services. For the web-based services, university libraries should collect, arrange, and preserve all types of information resources systematically to raise users access and convenience. Therefore, university libraries should be changed into a gateway, which emphasizes electronic collection and role of the internet. That is, university libraries should be a real space as well as a virtual space having collection ability and access paradigm. This research is intended to provide improvement plans through analyzing the collected data.

Russian State Historical Archive (Rossiiskii gosudarstvennyi istoricheskii arkhiv - RGIA) received its present name in June 1992, and before 1961 was known as TsGIA. RGIA holds the major records of high-level and central state and administrative institutions and agencies of tsarist Russia from the eighteenth century to 1910s (except the records of the Army, Navy, and the Ministry of Foreign Affairs), as well as fonds of social organizations, institutions, and individuals of prerevolutionary Russia. The main goal of this article is to assist understanding russian principle on arrangement and classification archives with its historical development focusing on one of the biggest historical archive in Russia. The primary set of historical records in RGIA remain arranged in 3-steps classification system: fond (collection) -- opis' (inventory) -- delo (file). In this general survey of RGIA author offers detailed information on the collection of archives and the system for classification of its huge amounts of primary sources in connection with influence upon historical studies. Despite the general economic crisis Russian archives are struggling to keep their doors open for public research and are exerting their energies in present electronic information to scholars and other researchers from throughout the world. The result, however, is not rewarded enough, considering the effort involved.
