Sensory Substitution, Key to Inclusive Learning

Visually impaired students, in primary education, encounter unique challenges while learning creative skills, exploring artistic expression and developing problem-solving skills, because so much instructional content is delivered visually. Sensory substitution—an approach that replaces visual information with feedback from other intact senses like touch, sound, taste or smell—provides an opportunity to address those challenges. Through the use of sensory substitution, this thesis proposes concrete ways to capitalize on the enhanced abilities of visually impaired primary school students. The research outcome of this thesis is a system of templates that puts these enhanced abilities to work for visually impaired students, to support them while they learn creative skills and practice problem-solving in a classroom setting. Each template contains a lesson that can be learned by using the process of paper quilling. The templates work equally well for sighted and visually impaired students, since all will be able to understand the lesson by using the sense of touch, as they learn by making

Analysis of grounding performance for different bio filler medium effect

The importance of grounding system is when any fault current due to the power system problem, or lightning, can allow that dangerous current passes through the earth. Although with current specification and standardization right now is sufficient, there is no harm to try to improve the performance of the grounding system continually. Thus, the primary purpose of this project is to design and develop a new ground rod prototype with new soil composition. This new soil composition is used bio-material which then will be used as a main material for the grounding medium. The grounding rod will have a two design which is based on the previous research data. There is no any major or significant change on the ground rod except the is of the small electrode at the bottom of this copper rod. The small electrode is designed into the position of horizontal and vertical and then combine with the small ground grid rod which can increase the current dispersion. The performances analysis for the grounding system was based on two main assessments which are the soil resistivity and ground rod resistance. The results show that the vertical ground rod is performing better compared to the horizontal ground rod in term of ground rod resistance. Besides, it shows the depth of the ground rod buried will affect the ground rod resistance significantly. As a conclusion, pineapple leaves filler shows better medium for enhancing the grounding system performance compared with coir filler due to lower lower grounding resistance. Copper sulfate was able to reduce the ground rod resistance value temporarily although for a short duration

The Determinants of Foreign Direct Investment in Pakistan: an Empirical Investigation

The changing modes of international transactions and the cross-border mobilisation of factor resources, in pursuance of transnational production, constitute new dimensions for sustained economic growth. Foreign Direct Investment (an influential element of this process) is defined as the source of acquisition of managerial control by a business enterprise of a foreign country over a business activity in a host country [Graham (1982)]. The changing perceptions and more attractive policies of the host developing nations have changed the destinations of FDI flows from industrially developed countries to high growth developing centres. FDI stock held by developing countries has risen from $132.95 billion in 1980 to$ 1438.48 billion in 1999. Their share in inward stock has reached to 30.14 percent in 1999 as against 26.2 percent in 1980. FDI inflows during this period were raised from $4.42 billion to$ 208.0 billion, at an annual growth rate of 22.5 percent while GDP growth rate for that period was 3.9 percent. FDI brings the most needed capital fund, advanced production technique, snobbish managerial skills, advertising and marketing expertise, global links and the controversial phenomenon of “transfer pricing”.1 Pakistan, the world’s 7th most populated country with 140 million people, a relatively high growth rate of GDP (averaging around 6 percent), with a significant stock of natural resources and a variety of investment provisions has remained unattractive for FDI inflows.

Charge Transport Scalings in Turbulent Electroconvection

We describe a local-power law scaling theory for the mean dimensionless electric current $Nu$ in turbulent electroconvection. The experimental system consists of a weakly conducting, submicron thick liquid crystal film supported in the annulus between concentric circular electrodes. It is driven into electroconvection by an applied voltage between its inner and outer edges. At sufficiently large voltage differences, the flow is unsteady and electric charge is turbulently transported between the electrodes. Our theoretical development, which closely parallels the Grossmann-Lohse model for turbulent thermal convection, predicts the local-power law $Nu \sim F(\Gamma) {\cal R}^{\gamma} {\cal P}^{\delta}$. ${\cal R}$ and ${\cal P}$ are dimensionless numbers that are similar to the Rayleigh and Prandtl numbers of thermal convection, respectively. The dimensionless function $F(\Gamma)$, which is specified by the model, describes the dependence of $Nu$ on the aspect ratio $\Gamma$. We find that measurements of $Nu$ are consistent with the theoretical model.Comment: 12 pages, 7 figures, Submitted to Phys. Rev. E. See also http://www.physics.utoronto.ca/nonlinea

Fine recycled concrete aggregate as a material replacement in concrete production

As a fast and rapid growing nation, Malaysia undergoes a lot of development especially in construction field. Most of the building nowadays are being made mainly using concrete as it provides many favorable features such as satisfactory compressive strength, durability, availability, versatility and cost effectiveness. However, in pursuing the development era, sometimes the authorities overlooked about the construction and demolition (C&D) waste that had been created along the development progress. Construction and demolition waste is becoming a vital issue especially to the environmental aspect in many large cities in the world (Chen et al., 2002). Shen [1] describe C&D waste as the waste which generated from renovation, site clearing, demolition, construction, roadwork, land excavation and civil and building construction. Construction and Demolition (C&D) waste constitutes a major portion of total solid waste production in the world, and most of it is used in landfills .

Scattering regimes for underwater optical wireless communications using Monte Carlo simulation

Optical wireless communications has shown tremendous potential for underwater applications as it can provide higher bandwidth and better security compared to acoustic technologies. In this paper,  an investigation on scattering regimes for underwater links using Monte Carlo simulation has been presented.While the focus of this paper is on diffuse links, the simulation results of collimated links is also provided for comparison purpose. Three types of water namely clear, coastal and turbid water are being used in the simulation. It is shown that the effect of scattering on the path loss cannot be accurately modeled by the existing channel model; ie. Beers-Lambert (BL) law.  It has been shown that  the distance at which the unscattered light drops to zero can be used to estimate the transition point for the scattering regimes in case of diffuse links. The transition point for diffuse links in coastal water and turbid water can be estimated to be around 22 m and 4 m respectively. Further analysis on the scattering order probability at different scattering regimes illustrates how scattering is affected by beam size, water turbidity and distance. From the frequency response plot, it is estimated that the bandwidth of several order of GHz can be achieved when the links are operating in the minimal scattering region and will reduce to several hundreds of MHz when the link is operating in multiple scattering region
