2. IN-SITU AND LABORATORY DETERMINATION OF THERMAL PROPERTIES OF TAR SANDS IN EASTERN DAHOMEY BASIN SOUTHWESTERN NIGERIA

by Oladunjoye M.A., Adefehinti A. & Sanuade O.A.

Abstract

In bitumen recovery from tar sand where heat transfer takes place through injection of thermal energy into the tar sand formation, it is of great importance to estimate the thermal properties of such tar sand. The aims of this research is to determine the thermal properties of tar sand in the Eastern Dahomey basin, Nigeria with a view to having more information in planning for thermal recovery of the tar sand.

Twelve locations were established along the tar sand belt in order to measure its thermal properties. The thermal properties of the tar sand were measured in-situ using KD2 Pro thermal analyzer. In laboratory, thermal properties of samples from each location were measured and their physical properties that influenced them (such as grain size distribution, percentage by weight of bitumen content, moisture content, bulk density, porosity and dry density of the samples) were determined. Thermal conductivity, specific heat and bulk density were used to calculate the thermal effusivity of the tar sands.

Positive correlations were observed between the values of the field and laboratory measurements of thermal resistivity, thermal conductivity, thermal diffusivity, thermal effusivity and volumetric specific heat with R-values 0.86, 0.85, 0.81, 0.78 and 0.49 respectively. It was observed that the thermal properties of the tar sand determined have close similarities with those reported on Athabasca tar sand of Canada. This implies that the thermal recovery process used in the Athabasca basin could also be employed in the Eastern Dahomey basin, Nigeria.

3. THE UNIVALENCE CONDITIONS OF SOME INTEGRAL OPERATORS
by Adriana Oprea & Daniel Breaz
Abstract

For analytic functions f, g in the open unit disk U, we define two new integral operators. The main object of this paper is to obtain the univalence conditions for the integral operators. Several corollaries of the main results are also considered.

4. A SURVEY ON VIDEO DETECTION AND TRACKING OF MARITIME VESSELS
by Rodrigo Da Silva Moreira, Nelson Francisco Favilla Ebecken, Alexandre Soares Alves, Frédéric Livernet & Aline Campillo-Navetti
Abstract

Maritime surveillance systems can be employed to increase the security of ports, airports, merchant and war ships against pirates, terrorists or any hostile vessel attacks, to avoid collisions, to control maritime traffic at ports and channels and for coastal and oil platforms defense. Cameras are one of the main sensors of these systems. They are cheap and complement other types of sensors. This survey was motivated by the importance of the subject, to motivate new researches and because there are no surveys about video detection and tracking of marine vehicles or they are not widespread. It is an insignificant quantity compared with other kinds of video surveillance systems. The paper presents the state of the art algorithms.
