Character Development Creativity in Unit Blocks for Visual Spatial Intellegence Improvement of Children with Special Needs

Autism is a neurodevelopmental disorder that is present from birth or early childhood. People with autism usually have impaired social interaction, difficulties in verbal and non- verbal communication, and repetitive behaviour. One of the forms of autism treatment is therapy. Vision therapy through toys that require concentration and creativity is able to treat autism as it won’t limit the imagination of children with the disorder. Toys usually have their own patterns and programs that tend to limit children’s creativity, imagination and visual and spatial intelligence. This can lead to children’s stress and lack of confidence. A character design on unit block toys is a form of vision therapy. It develops children’s visual and spatial creativity and intelligence. It also helps children to be independent and helps with their perception. Unit blocks consist of pieces of wooden blocks with different shapes and sizes that can form even bigger shapes, based on children’s imagination and ability to design a space or a building. Children’s visual and spatial intelligence help them visualize and notice shapes, colours, spaces, and designs of the unit blocks accurately, modify their surroundings based upon their perceptions, and recreate the aspects of their visual experiences. Playing Lego blocks will help develop the visual spatial intelligence of children with autism as it stimulates their ability to express ideas and to design a character the way they like.

On-screen fingerprint sensor with optically and electrically tailored transparent electrode patterns for use on high-resolution mobile displays

In this study, a mutual capacitive-type on-screen fingerprint sensor, which can recognize fingerprints on a display screen to provide smartphones with full-screen displays with a minimal bezel area, is fabricated. On-screen fingerprint sensors are fabricated using an indium tin oxide transparent conductor with a sheet resistance of ~10 Ω/sq. and a transmittance of ~94% (~86% with the substrate effect) in the visible wavelength range, and assembled onto a display panel. Even at this high transmittance, the electrodes can degrade the display quality when they are placed on the display. The interference between periodic display pixel arrays and sensor patterns can lead to the Moiré phenomenon. It is necessary to find an appropriate sensor pattern that minimizes the Moiré pattern, while maintaining the signal sensitivity. To search for appropriate patterns, a numerical calculation is carried out over wide ranges of pitches and rotation angles. The range is narrowed for an experimental evaluation, which is used to finally determine the sensor design. As the selected sensor pitches are too small to detect capacitance variations, three unit patterns are electrically connected to obtain a unit block generating a larger signal. By applying the selected sensor pattern and circuit driving by block, fingerprint sensing on a display is demonstrated with a prototype built on a commercial smartphone.

Development a general-service weighting batcher with automatic control

A general-service weighting batcher with automatic control, which is related to the field of packaging equipment and is intended for weighing and dosing of food or non-food bulk production, has been developed. The existing constructions have been studied and patent search of analogues has been carried out. The kinematic scheme of the mechanism has been drawn out on the basis of analysis of study subject analogues. The construction of the dosing unit, block diagram and operation algorithm of automatic control system of the batcher have been developed. Modeling and research of the device construction have been carried out. Choice of optimal dimensions of the device has been grounded mathematically.

Life Cycle Assessment of EI of Masonry Materials

The wide usages of masonry materials in construction are always accompanied by great consumptions of energy and resource during their life cycle, so it is necessary to evaluate the EI of masonry materials objectively. This paper uses BEPAS, an LCA-based quantitative EI assessment system developed based on our previous studies, to assess the life cycle EI of three kinds of common used masonry materials: autoclaved flyash brick, sintered clay brick and aerated concrete block. Starting with establishing the environmental profiles at the producing, constructing and demolishing phases of these three materials respectively, the environmental impacts are categorized into three safeguard subjects: ecosystem damage, resources depletion and health damage. Then, based on WTP (willingness-to-pay) method and the updated monetization weighting factors, one integrated EI value per functional unit (10m3) of masonry partition wall is obtained. Finally, a comparative study is conducted on the EI values to analyze and compare the life cycle environmental performance of the three materials, resulting that autoclaved flyash brick is the most environmental friendly in a sharp contrast to sintered clay brick. Results also indicate that reusing more wastes, as well as reducing weight and increasing the volume of unit block are the most effective measures to improve the environmental performance for masonry materials.
