Sustainable Development of the Nile River at Greater Khartoum
No full textSudan is the largest country in Africa, but there is poverty and a lack of infrastructure, skills and opportunity despite its substantial natural resources. The capital of Sudan is Khartoum City,
located at the confluence of the Blue and White Nile Rivers. Unfortunately development on Nile
River Front is limited due to the risk of flooding and erosion. There is a danger that rapid
economic development may take place in this unique area without sustainable development
planning. This research project aims to develop strategies to protect the Nile River banks by
suitable stabilization methods so that development can take place safely.
Data has been collected about hydrology, morphology, geotechnical factors, soil classifications, river pattern systems, driving forces, and the main problems restricting sustainable development and engineering works for the Nile River. In addition the following have been reviewed: historical background, existing land uses, current environmental situations, and the economic and social conditions of the study areas. Research identified Cairo, Egypt as a similar case study, where data collected by the author included historical background, current situations, strategic visions and development plan for Nile River Shores. Further information was collected about sustainable development from a general literature review.
From these collected data a set of guidelines and indicators for sustainable development was
established related to environmental, economic and social factors. Based on those guidelines and
indicators, methods of stabilization of the banks for each shore were specified and a proposed
development plan was established. Methods of stabilization of banks and the development plan
were refined and evaluated to establish a final version of the development plan: Sustainable
Development of the Nile River Front (SDNRF) at Greater Khartoum. From refinement and evaluations, barriers and constraints for implementation were specified with their suggested
solutions. Finally, conclusions and recommendations related to the SDNRF Manual about
development and regulations were established

RGtk2: A Graphical User Interface Toolkit for R
No full textGraphical user interfaces (GUIs) are growing in popularity as a complement or alternative to the traditional command line interfaces to R. RGtk2 is an R package for creating GUIs in R. The package provides programmatic access to GTK+ 2.0, an open-source GUI toolkit written in C. To construct a GUI, the R programmer calls RGtk2 functions that map to functions in the underlying GTK+ library. This paper introduces the basic concepts underlying GTK+ and explains how to use RGtk2 to construct GUIs from R. The tutorial is based on simple and pratical programming examples. We also provide more complex examples illustrating the advanced features of the package. The design of the RGtk2 API and the low-level interface from R to GTK+ are discussed at length. We compare RGtk2 to alternative GUI toolkits for R.
Facing the growing problem of the electric power consumption in Egyptian residential building using building performance simulation program
No full textEgypt has been experiencing recurrent power cuts especially at the summer, with the problem being made worse by the extra demands placed on the electrical grid by the advent of the holy month of Ramadan. Electricity shortages are now a problem in Cairo, Alexandria, Sohag, Qena, Luxor, Aswan, and Nubia, as well as in the Nile Delta governorates of Beheira and Qalioubiya. The aim of this study is to develop a model for the Egyptian residential building using Building Performance Simulation Program and make sensitivity analysis on some variables effecting the electric power consumption in order to help faceting the growing problem in Egypt. The model was created using the IES-VE 2012 (Integrated Environmental Solution ). The simulation model was verified against the survey data for the Egyptian apartment and same model simulated using energy Plus simulation tool. The results of the program describing different situations for energy using profile for the air conditions, lighting and equipments in respect to building layout and construction climate and pattern of use. This model can be used in the future to help in reducing the electric power consumption in the residential building
On the determination of the spatial energy balance of a megacity on the example of Cairo, Egypt
No full textThis research deals with different aspects of the spatial urban energy balance on the example of the megacity Cairo, Egypt. The energy balance and its single terms were measured in situ during a field campaign in Cairo at three different locations (urban, suburban agricultural and suburban desert) from November 2007 to February 2008. The net radiation and the heat fluxes showed distinct variations between the three stations, representing part of the spatial diversity of the area. The net radiation was highest at the suburban-agricultural location; lowest values were recorded at the suburban-desert station. The urban station ranged in between. The soil heat flux was only measured at the two suburban sites and proved to be highly dependent on the storage term. While the urban and the suburban-desert station had comparable turbulent heat fluxes, the suburban-agricultural station stand out with a low sensible but very high latent heat flux. Cairo acted as a nocturnal heat island - comparing the urban with the two suburban stations. During the day however, the suburban-desert temperatures topped the urban temperatures.
The spatial diversity was also captured using various remote sensing approaches using ASTER satellite data. The strong heterogeneity of the area of interest proved to be the major challenge for the different approaches. The estimation of the net radiation was dependent on a accurate atmospheric correction, which was complicated by the heavy, but spatially varying air pollution over the megacity. The determination of the ground heat flux was done using empirical equations. Some of the used approaches proved to be applicable even in this extreme environment. One promising, as simple approach for the turbulent heat fluxes (S-SEBI: Simplified Surface Energy Balance Index) was not usable in the area due to observed high variations in surface temperatures in the desert. Two other approaches (LUMPS: Local-Scale Urban Meteorological Parameterization Scheme and ARM: Aerodynamic Resistance Method) could be used to deduct turbulent heat fluxes in a satisfactory range. However, the spatial analysis showed that more research is needed to represent turbulent fluxes in such a heterogeneous area. Besides this, a small study on the estimation of aerodynamic resistance to heat using morphometric methods was conducted. The study showed that the aerodynamic resistance to heat can be estimated successfully from a digital surface model, knowing surface specific empirical parameters.
Besides the energy balance research, also the CO2 flux and concentrations were analysed. The CO2 flux showed a clear weekly dependence on the traffic, but generally fluxes were low considering the strong emissions induced by the old cars and the heavy traffic of Cairo. This result might be due to the spatial distance of the measurement to the streets.
Two in-depth studies about the urban albedo were conducted additionally to the flux research, analysing the dependence of the satellite measured albedo on the sun’s position, atmospheric scattering, housing density and viewing angle
Wind Energy in Egypt: Economic Feasibility for Cairo
No full textMotivated by the rise of the electricity tariffs applied on industrial customer and the frequent electricity cut offs recently experienced in Egypt, this paper assesses the economic feasibility of installing a stand alone wind energy technology by an industrial customer who seeks to reduce his dependency on the national grid. For this purpose, the wind energy potential at the wind regime of Cairo was chosen to be assessed using half an hour wind speed data for a full one-year period (2009). The Weibull parameters of the wind speed distribution function were estimated by employing the maximum likelihood approach. The estimation revealed that Cairo has poor wind resources. Despite the poor resources, the financial analysis has shown that under certain parameters the wind project can prove to be financially viable. Thus harnessing wind energy through stand alone systems can help in meeting the industries electric power needs.Renewable energy, wind resources, Weibull distribution, electricity

The plight of women in Egyptian cinema (1940s 1960s)
No full textIt has been suggested that the period between the 1940s and the 1960s was 'the golden age' of Egyptian cinema -a period of growth, innovation and popularity. The aim of this research is to focus on the plight of Egyptian women in selected long feature films of this period, and how this -was realistically represented on the screen. It was a daunting task for the present researcher to embark on such controversial gender issues, especially from a westerner's perspective on a Muslim Arab society. But the researcher's determination and sense of duty to investigate and expose the hardships of Egyptian womenfolk through films, managed to overcome that feeling of trepidation, together with the tremendous support of her advisor Dr. Zahia Salhi.
This study begins by tracing the historical development of Egyptian cinema and the important role played by female pioneers in the newly emergent film industry, whereby an assessment of the role of these pioneers is also considered. This leads to an analysis of the status of the Egyptian woman within her socio-historical and cultural contexts that are essential for the identification of gender based representational strategies in these films. The research reviews major film theories related to representation, communication and gender issues, and how films as products of their creators, are connected to the social, economic, political and cultural backgrounds of a given time and place. In addition to these film theories,
the study recommends a textual variation approach for film analysis, for those films based on literary texts that have been adapted to the screen. The textual variation
approach looks for the ways in which the film director modifies the original text when it is adapted into a film. The aim behind the textual variation approach is tounderstand the function of the dominant theme in both literary text and film, and scrutinise its visible or latent realistic meanings vis ii vis the structures of thought which dominated the Egyptian society of the 1940s to the 1960s. It is these structures of thought that impose on the film-makers the textual variations from novel to film. The difference in the time period when the novel was written is compared with the period when the film was produced in order to assess the present social dominant ideologies or the shifting values. Thus, the time dimension factor, together with the film-makers' own views, help us determine the internal expectations of the Egyptian society and the realistic plight of its womenfolk. To bring the concept of textual variation into application, three film case studies are considered, th e findings of which demonstrate that when textual variations or total
adherence to the novel were involved, dominant ideologies were either reaffirmed, shifted or evolved according to the era of the film production
