An effective continuum/finite element (FE) approach for modeling the structure and the deformation of single- and multi-wall carbon nanotubes (CNTs) is presented. Individual tubes are modeled using Frame like structure with beam elements., The effect of van der Waals forces, crucial in multi-wall nanotubes, is simulated by the construction of spring elements. The success of this new CNT modeling approach is verified by comparing simulations of deformation of single-wall nanotubes with molecular dynamics results available in the literature. Simulations of final deformed configurations are in excellent agreement with the atomistic models for various deformations. The approach was then applied to the multi-wall carbon nanotubes (MWNTs), and the deformed configurations were compared to corresponding pervious data. The proposed approach successfully predicts the experimentally observed values mechanical behavior of SWCNTs and MWNTs. Presented results demonstrate that the proposed FE technique could provide a valuable tool for studying the mechanical behavior of different type of nanotubes, as well as their effectiveness as load-bearing entities in nanocomposite materials.

This paper proposed an effective disparity estimation algorithm based on census transform with adaptive support weight, called small-color census and sparse adaptive support weight (SCCADSW). Census transform provides high resistance to radiometric distortion, vignette, and noise because it are based on the relative ordering of local pixel intensity values rather than the pixel values themselves. This transform is widely used in many computer vision applications. A simplification technique such as using small-color census is used to determine the initial matching cost. The color distances are transformed using small census transform to keep the information of the color. To derive support weights, Manhattan distances are used for all pixels of the support window to the window's center point. Property of adaptive support weight leads to improved segmentation results and consequently to improved disparity maps. This work is still on process, to test the algorithm; it will use the Middlebury benchmark. According to analysis of each step of the algorithms, the proposed SCCADSW can achieve good performance among stereo methods that rely on local optimization.

In this paper, an objective method for the evaluation of mental stress has been proposed using physiological sensors. Brain and autonomous nervous system are believed to be affected by stress. It will be useful to measure the changes of physiological signals in these parts to evaluate stress. Stress stimuli which should be used in physiological studies to evolve stress has very crucial role in generating good results. Correlation of results from multiple sensors data can enhance the accuracy of results and can provide a common metric to evaluate mental stress.

Halloysite nanotubes filled nanocomposite films based on polyvinyl alcohol (PVA)/chitosan (CS) blend were prepared via solution casting method. Tensile, morphology and swelling properties of the nanocomposite films were investigated. Addition of 0.5 wt% filler leads to improvement in tensile strength, elongation at break and Young modulus of the nanocomposite films. Increase roughness and tearing in the fracture surface morphology further supports the tensile results. Moreover, the presence of HNT in the blend reduced the swelling of the nanocomposite films in distilled water.

This experimental work focuses on the effects of super plasticizer and curing temperature on the workability and compressive strength of self-compacting geopolymer concrete (SCGC). SCGC is an improved way of concreting execution that does not require compaction and is made by complete elimination of ordinary portland cement content. The parameters investigated were superplasticizer (SP) dosage and curing temperature. SCGC were synthesized from low calcium fly ash, activated by combinations of sodium hydroxide and sodium silicate solutions, and by incorporation of superplasticizer for self compactability. The SP dosages were 3%, 4%, 5%, 6% and 7% and the different curing temperatures were 60°C, 70°C, 80°C and 90°C. The effects of SP dosage on workability properties such as filling ability, passing ability and resistance to segregation were evaluated. The fresh properties were measured using slump flow, T-50 V-funnel, L-Box and J-ring test methods. The essential workability requirements for self compactability according to European Federation of National Associations Representing Producers and Applicators of Specialist Building Products for Concrete (EFNARC) were satisfied. Results showed that the workability and compressive strength improved with the increase in Super plasticizer dosage. An increase in strength was observed with the increase in curing temperature up to 70°C. However, the strength decreased when the curing temperature increased beyond 70°C. The compressive strength of 51.52MPa was obtained for SCGC with SP dosage of 6% and cured at 70°C oven temperature.

Ants are abundant, diverse and ecologically dominant. P. longicornis is an invasive ant which is accidentally spread by human commerce around the world. P. longicornis may act as a predator upon pest species in plantations and agriculture farms. In spite of that, this cosmopolitan ant species is also a pest in houses (Fox et. al, 2007). P. longicornis is one of the most common ants found in buildings and would be the first species to arrive in a newly disturbed habitats or new buildings (Lee, 2002). The aim of this study is to determine and compare the variation in behaviour and nesting of P. longicornis found in wooden and concrete houses. Thus, this study intends to update all biological information on P. longicornis that is not much being studied worldwide.

Public private partnerships (PPP) or Private Finance Initiatives (PFI) are the new age procurement strategy used by many governments across the world to provide the much needed world-class public services for their citizenry. The strategy emanated from the UK in 1992 and has spread across the entire globe though in varying degrees. Developing countries are still trying to find their feet under this procurement strategy, the reasons for this lethargy stems from a number of factors which though within the purview of these countries but has continued to elude them. Public private partnerships adoption is meant to curb sovereign debt burden, increase Value for Money (VFM) of constructed assets, manage the risks of time and cost overruns, improve the quality of the final product, improve efficiency of public services, assist in public sector reforms under the New Public Management (NPM), reduce project life-cycle costs, promote local economic growth, strengthen national infrastructure, hasten development and create a private sector-led economy. The above benefits are indeed novel however achieving them using this procurement strategy requires the fulfillment of a number of conditions; therefore it is the aim of this paper to highlight the barriers and conditions that must be met for this procurement strategy to thrive in developing countries

Floatover barges are used for the installation of topsides onto jacket platforms recently. In this study, a frequency domain analysis was performed for a float-over barge subjected to random waves. The excitation forces acting on the floating barge were derived by Froude-Krylov approach. In this paper, seven different sea states were specified for the analysis and the results are presented in terms of Response Amplitude Operators (RAOs). Three motion modes were analyzed namely surge, heave and pitch. The results are presented and conclusions arrived at. The resulting RAOs decrease with an increase in draft while longer wave periods are associated with larger surge, heave and pitch responses. The findings provide guidance for the conceptual design and development of such structures.
