AbstractAbstract
[en] The Wireless Sensor Network (WSN) is composed of a large number of sensor nodes with limited computation communication, and battery facilities. One of the common applications of this network is environment monitoring through sensing motion, measuring temperature, humidity and radiation. One of the basic activities in WSN is data gathering which represents a great challenge. Many routing protocols are proposed for that network to collect and aggregate the data. The most popular ones are hierarchy and data centric routing protocols. The main goal of this study is to identify the most preferable routing protocol, to be used in each mobility model. This paper studies the performance of LEACH (Low Energy Adaptive Clustering Hierarchy) from hierarchy routing protocol and direct diffusion from data centric routing protocol which is not clarified until now. Moreover, a comparison between LEACH and direct diffusion protocol using NS2 simulator will be made, and an analysis of these protocols will be conducted. The comparison includes packet delivery ratio, throughput, average energy ratio, average delay, network lifetime, and routing overhead. The performance is evaluated by varying the number of sensor nodes under three mobility models Reference Point Group Mobility Model (RPGM), Manhattan and random waypoint mobility model. Simulation results show that LEACH routing protocol has a good performance in RPGM and Manhattan than random waypoint mobility model. Direct diffusion has a good performance in random waypoint mobility model than in RPGM and Manhattan mobility model

AbstractAbstract
[en] The contribution comprises analysis that is based on scientific work as a part of participation on the international research project carried out at the University of Prešov in Prešov and Vienna University of Technology entitled 'Detection and Management of Risk Processes in Building Insulation' and numbered SRDA SK-AT-0008-10. Statistical approach with correlations among humidity, time and temperature values in the space between the wall and building insulation uses the set of data obtained during the measurement series as testing using a new technology with equipment that does not influence the environment properties in the space. Therefore such real mapping can bring a real picture of possible condensation as a risk process in the building envelope.

AbstractAbstract
[en] Regimes in moist stratified flows over simply shaped 3D mountains have been studied in numerical simulations made with a mesoscale meteorological model. One of the aims that this work intends to examine is the possible existence of multiple solutions, searching for different solutions depending on the path followed by the system in the parameter space. Results from three different sets of experiments are discussed here. In the first set of simulations, the height of the mountain has been progressively changed in time. In the second group of experiments, the humidity of the air flowing over the obstacle has been increased in time by adding a source term to the equation of evolution of moisture. The case of advection of moist air towards an obstacle, initially embedded in dry air, has been studied as a third type of flow. A dependence on the past history of the flow seems to characterize some types of system evolution, leading to different flow regimes over the obstacle. The experiments indicate that this result is mainly a consequence of changes of state of water, associated with the presence of humidity in the atmosphere. These effects are emphasized in the case of an elliptical mountain, with its longer axis perpendicular to the main flow. In the three different sets of experiments presented here, evident differences with simulations where flow parameters are kept constant from the beginning persist in the flow regimes, also for periods of time much longer than the characteristic time of evolution towards stationary solutions

Isotope techniques in the study of environmental change
Isotope techniques in the study of environmental change
AbstractAbstract
[en] In 1989, within the framework of the Etude de precipitations par satellite (EPSAT) operation, an isotopic study of precipitation and its atmospheric context (temperature and humidity) was performed along the Guinean monsoon trajectory between Cotonou and Agades. The dewatering process which progressively affects the air masses over the continent is stopped at the sub-Sahelian latitude. Precipitations and their surrounding environment are therefore the reflection of new conditions of humidity linked to a large contribution of recycled vapour. (author)

AbstractAbstract
[en] Reliability testing of cable on humidified condition has been carried out. As a result, the failure occurred due to reduction of current by increasing the resistance on rising temperature testing. For humidified condition the result which are observed did not significant at the stated condition of testing. The needed time up to the failure criteria increased as a temperature testing increased

AbstractAbstract
[en] In the process of nuclear radiation measurement, often the results relied on measuring the temperature and humidity of the environment to compensate. The design of a low-cost simple temperature and humidity logger in the article, can achieve the measurements of temperature, humidity in the experimental nuclear environment. The system uses AT89 series low-cost MCU controller, domestic DHT11 temperature and humidity sensors, and RS485 protocol for remote data transfer and on-line monitoring of results. Experimental results show that the collector can achieve rapid multi-point measurements of temperature and humidity, the system is stable and reliable, is a low-cost solution, suitable for all kinds of nuclear measurement applications.

AbstractAbstract
[en] Increasing numbers of galleries, museums and archives are including ink jet printed materials into their collections, and therefore displays. There is evidence that the instability of these prints is such that images can suffer deterioration in print quality or in extreme cases, a loss of information over an extended period of time. This is shorter than the period typically required for perceptible deterioration to occur in many other paper-based artworks. The image stability of prints is affected by a number of factors some of which have already been studied. However the role played by the ink solvent in the loss of image quality has yet to be explored. This paper will outline research being undertaken to investigate the effects of solvent content which may increase/promote the loss in image quality of the hard copy prints when stored or displayed under a range of temperature and humidity conditions.

AbstractAbstract
[en] An Infra-Red camera has been used to reduce errors and to save time, cost and efforts for measurement of temperature distribution. Because allowable ranges of major factors that affect results of the measurement of the IR camera had not been established yet, this study has been performed to investigate the major factors and ranges for the effective measurement techniques. In this study, surface temperature, surrounding humidity, distance between the camera and the surface, incident angle, and emissivity of the surface have been considered as the major factors for the experimental setup. Especially, it has been observed that the results of the IR camera have been affected by the surface emissivity greatly.
