Noise is a common problem in most of the image understanding analysis. Border noise is one of the common document noises that are introduced when scanning and/or capturing thick books and old books. This noise is responsible for non-accurate results for document image analysis system as example OCR engines. In this paper we introducedan algorithm which can effectively remove the border noise from the document image by using X-Y cut and filtering technique based on morphological operations. We evaluate our technique on CBDAR 2007 document dewarping dataset and make comparison with other state-of-art methods. The experiment results show the high performance of the algorithm in removing the border noise (textual and non-textual noise) for a variety of documents with different levels of complexity and different structure. The used documents include diagrams, figures, formulas and different languages (English, Arabic, Chinese and Japanese document). © 2015 by IJIR (CESER PUBLICATIONS).

As education and concern pertaining to environmental and sustainability issues like implications of resources destruction, decrease in bio-diversity as well as climate change multiply, so has the need for housing developments that lead to less damaging effects on the environment, whilst enabling living standard to be sustained. Builders, developers and material providers have addressed this demand by creating approaches and technologies that minimize energy, water and main material consumption, decrease greenhouse gas emissions and sustain or enhance surrounding ecological systems and services. Several administration and non-governmental institutions in addition have aimed to change the sustainability of the building industry by developing green rating systems that can be used to evaluate the environmental performance of new and existing building. This paper discusses material resources criteria and the impact as a sustainable rating tool. © (2013) Trans Tech Publications, Switzerland.

High permeable concrete (HPC), due to its high void ratio and permeability, is considered as an option to substitute the conventional impervious pavements for managing stormwater runoff in a cost-effective and friendly environmental way. HPC is made of single graded sized of coarse aggregate bound together with ordinary cement without or with little fine aggregate. Due to its low compressive strength, HPC is only used as pavement material. For the purpose of developing a new type of HPC with enhanced structural strength without compromising its permeability, five pozzolanic materials (fly ash, silica fume, paper-mill ash, palm oil ash and rice husk ash) were used as partial replacement to ordinary cement. Their effects on the compressive strength, void ratio and permeability of HPC were investigated. It was found that 5% of cement replacement with pozzolan will lead to enhance the compressive strength and permeability of HPC. © 2013 IEEE.

Interest on building insulation has started to develop among the research community in recent years. Kapok fibres have the potential to become a roof insulation material because of its low thermal conductivity. This paper reviews studies on kapok fibre as insulation material. It is revealed that there were no reported findings on the application of kapok fibre as roof insulation.Thorough study is highly recommended in this area since kapok fibre has good thermal and acoustic properties. © (2014) Trans Tech Publications, Switzerland.

In this progressive world traffic congestion is a critical issue. It results in huge amount of time and resources loss. Vehicles in congestion is a valuable parameter for drivers to anticipate the state of congestion. The proposed approach is based on relating the relationship of different transmission ranges with vehicle density. This research work uses a GrooveNet simulator, which is based on real street maps and plays a major role in discovering and disseminating congestion information. Our simulation results are based on average values of number of vehicles caught in congestion with respect to transmission range and vehicle density. © 2014 IEEE.

The use of viscosity temperature relationships to predict creep performance of road bitumens have been shown to be inadequate in particular with respect to the analysis of polymer modified binders. In this paper we explore the origins of the US Strategic Highway Research Programmebinder performance grading system and detail two examples of more recent developments towards improved creep characterisation.Starting from first principles, an equation to analyse the ratio of dissipated to stored energy during sinusoidal loading of viscoelastic bitumen was derived. The energy equation was contrasted with an empirical relationship proposed by Anderson D.A., and with a second more theoretical derivation proposed by Shenoy A.Using frequency sweep data from a conventional 40/50 pen grade bitumen and a proprietary SBS modified binder, the applicability of the energy equation was subsequently compared to the two aforementioned post-SHRP creep relations. Recommendations are made regarding the suitability of the proposed relations in ranking bitumen creep performance. © (2014) Trans Tech Publications, Switzerland.
