VARIABILITY AND DECADAL EVOLUTION OF TEMPERATURE AND SALINITY IN THE MEDITERRANEAN SEA SURFACE

Lamri Nacef, Nour El Islam Bachari, Abderrahmane Bouda, Riad Boubnia
Based on the Med-Atlas 20002 database data at Mediterranean Sea surface, analysis of spatial and temporal variations of temperature and salinity, as well as, the search of its possible trends are the main goals of this work. The used statistical techniques allowed us to obtain various climatological fields of temperature and salinity, on a period of 45 years (1955-1999). Spatial and temporal analysis of those fields shows that the north-south gradient is weaker than the east-west gradient. The s...

EVALUATION OF RECENT GLOBAL GEOPOTENTIAL MODELS BY GNSS/LEVELLING DATA: INTERNAL AEGEAN REGION

Mustafa Yilmaz, Bayram Turgut, Mevlüt Gullu, Ibrahim Yilmaz
Global geopotential models of spherical harmonic coefficients are used to determine the external gravitational field of the Earth. These coefficients are derived from satellite orbit perturbations, terrestrial gravity anomalies and altimeter data. Hundreds of thousands of coefficients and standard deviation values for these coefficients are estimated from millions of observation. Measurement amount, homogenous distribution of the measurements of global scale, different measurement types reflecti...

THE PROPOSAL OF THE BUILDING APPLICATION FOR MORE BENEFITING FROM SOLAR LIGHT

Nuri Erdem, Hüseyin Ince
There is a proverb, that emphasizes the importance of sunlight for human health, which is “Where the sun does not enter the physician enters”. It is one of the most important elements to see the sunlight of the buildings for both healthy life and energy saving. The positioning may be desirable to take the advantage of the morning and evening sunlight of the buildings to be constructed in the housing area. Indeed, in 1985 constructed blocks of buildings in Eskisehir Yenikent in public housing pr...

THE EFFECT OF JPEG COMPRESSION IN CLOSE RANGE PHOTOGRAMMETR

?zgün Ak?ay, Ramazan Cüneyt Ereno?lu, Emin ?zgür Av?ar
Digital photogrammetry, using digital camera images, is an important low-cost engineering method to produce precise three-dimensional model of either an object or the part of the earth depending on the image quality. Photogrammetry which is cheaper and more practical than the new technologies such as LIDAR, has increased point cloud generation capacity during the past decade with contributions of computer vision. Images of new camera technologies needs huge storage space due to larger image file...

DETERMINATION OF TRANSPORTATION NETWORKS BASE ON THE OPTIMAL PUBLIC TRANSPORTATION POLICY USING SPATIAL AND NETWORK ANALYSIS METHODS: A CASE OF THE KONYA, TURKEY

Mevlut Uyan, Emra Sert, Nurullah Osmanli, Rezzan Eruc
Public transportation planning is one of the most important parts of transportation planning and it provides sustainable development for cities. According to only demands of citizen’s and decisions of city managers obstruct for public transportation planning also taking policy in the long time period. Citizen’s demands and city manager’s decisions important factors in transportation planning but the other important factors; city’s and citizen’s characteristic features. Relational structure to be...

OPEN GEOSPATIAL CONSORTIUM WEB MAP AND FEATURE SERVICES AND FREE/OPEN SOURCE SERVER/CLIENT SOFTWARES

Mesud Behlül VAROL, Do?.Dr. ?smail ?ANLIO?LU
Usage of geospatial data enables decisions to be more effective and stronger in critical fields. Since geospatial data is very expensive source and the most time-consuming step, mostly it is not possible to find the required data ready to use. Therefore different projects have been developed and tried to implement by several countries to keep geospatial data which is required to collect and managed, accessible and usable. At this study Open Geospatial Consortium standarts were explained, the fo...

COMPARING UNIFORM AND RANDOM DATA REDUCTION METHODS FOR DTM ACCURACY

Mustafa Yilmaz, Murat Uysal
The digital cartographic representation of the elevation of the earth's surface created from discrete elevation points is defined as a digital terrain model (DTM). DTMs have been used in a wide range of applications, such as civil planning, flood control, transportation design, navigation, natural hazard risk assessment, hydraulic simulation, visibility analysis of the terrain, topographic change quantification, and forest characterization. Remote sensing, laser scanning, and radar interferometr...

LEAST COST PATH ALGORITHM DESIGN FOR HIGHWAY ROUTE SELECTION

Fatih SARI , MEHMET SEN
Highway route design is a difficult process due to the complex structure of the environment. The topography and the natural geographical objects constitute an obstacle for highway constructions. On the other hand, the cost parameter and protecting the environment are main two issues which planners have to consider. Thus, the priorities of the highway routes should be decided according to the requirements and expectations. At this point, Least Cost Path Algorithm (LCPA) makes it possible to i...

Analysis of Physical, Thermal, and Structural Properties of Biofield Energy Treated Molybdenum Dioxide

Mahendra Kumar Trivedi, Rama Mohan Tallapragada, Alice Branton, Dahryn Trivedi, Gopal Nayak, Omprakash Latiyal, Snehasis Jana
Molybdenum dioxide (MoO2) is known for its catalytic activity toward reforming hydrocarbons. The objective of this study was to evaluate the effect of biofield energy treatment on physical, thermal, and structural properties in MoO2. The MoO2 powder sample was divided into two parts, one part was remained as untreated, called as control, while the other part was subjected to Mr. Trivedi’s biofield energy treatment and called as treated. Both control and treated samples were investigated using X-...

Studies on Physicochemical Properties of Biofield Treated 2,4-Dichlorophenol

Mahendra Kumar Trivedi, Alice Branton, Dahryn Trivedi, Gopal Nayak, Ragini Singh, Snehasis Jana
The chlorinated phenols are widely used in chemical industries for the manufacturing of herbicides, insecticides, etc. However, due to consistent use they create hazards to the environment. This study was designed to use an alternative method i.e. biofield energy treatment and analyse its impact on the physicochemical properties of 2,4-dichlorophenol (2,4- DCP), which are the important factors related to its degradation. The 2,4-DCP sample was treated with Mr. Trivedi’s biofield energy and analy...
