摘要： In this demo we present a tangible UI concept for controlling the color of lighting. The interaction is performed by placing different color glass objects to a bowl of water. The system demonstrates an aesthetic design for a tangible UI, and aims to provide the user an experience-rich haptic UI. The demo aims towards decorative and calm UIs for home control systems. It seeks to hide conventional technology and switches, and is part of the ubiquitous computing design vision for calm computing.

A efficient light-controlled nitric oxide releaser in aqueous solution and its red fluorescence imaging in lysosome
摘要： In this work, a sensitive light-controlled turn on nitric oxide releaser, chromenylium-aniline-N-nitroso (CA-NO), was developed, which could release nitric oxide in pure water media and be applied for the red fluorescence imaging in lysosome. Upon the irradiation, fluorescence of the nitric oxide releaser enhanced quickly due to the light-controlled CA-NO being decomposed into a free radical nitric oxide and the fluorescent group CA, which destroyed of ICT structure. The mechanism was supported by the capture of nitric oxide by the commercial nitric oxide fluorescent probe DAN and the HRMS spectra peak (HRMS calcd for C30H34N3O4+: 526.2700, found: 526.2700.) belonging to CA. The fluorescence quantum yield (ΦF) of CA-NO changed from 0.54% to 3.24%. The nitric oxide releasing yield was calculated to be 91.3%, which proved the superiority of CA-NO. With the irradiation, the color of the solution immediately changed from pink to blue purple in visible light which realized the naked-eyed monitoring of nitric oxide releasing. Obvious fluorescence changes and high cell viability above 80% encouraged us to apply CA-NO into living cells and the CA-NO successfully released nitric oxide in living cells through under irradiation. Nitric oxide could easily diffuse into lysosomes and react with related proteins, which prompts nitric oxide to regulate lysosomal catabolism and autophagy. Therefore, the co-location experiment of CA-NO and Lyso Tracker Green in living cells was carried out and the co-localization coefficient was calculated to be 0.842, which implied that morpholine group promoted the nitric oxide releaser to be aggregate in lysosome successfully. This work achieved the fixed-point and quantitative release of nitric oxide, which was helpful to understand the roles of nitric oxide and provided a good basis for our studying on related interaction between protein and nitric oxide in lysosome and cells.

Arduino Based Traffic Light System With Integrated LED Advertising Display
摘要： Rapid advancement in scientific knowledge and growth in worldwide economic activities has led to a steep rise in the volume of vehicular activity for human and product mobility controls hence in addition to controllers are, therefore, a critical necessity of the modern – day society. Toward this end, this paper is aimed toward the design of microcontroller-based traffic control device taking as a case study the complex layout and linkage among the service roads of the Senate building and College of Science and Technology, Covenant University, Nigeria. The Arduino platform is the microcontroller preference for this idea. Also, to make this idea more effective and productive, a Light Emitting Diode (LED) advertising displays has been incorporated into its implementation to take advantage of the red light wait time to disseminate useful information or facts.

Performance study of a new type of transmissive concentrating system for solar photovoltaic glass curtain wall
摘要： There are many problems in Building Integrated Photovoltaics (BIPV) system, such as contradiction between daylighting and electricity generation, unable to match the demand of light control, need to constantly adjust angle for tracking, and so on. A new type of transmissive concentrating system for glass curtain wall is proposed which can improve the performance of solar photovoltaic glass curtain wall. The concentrating characteristic was studied by a series of comprehensive simulation and experiment. The optical software is used to simulate the influence of concentrating characteristics in different incident angles. Compared with solid and trapezoidal structure compound parabolic collector, the concentrating performance of hollow with water structure is also simulated. Simulation results shown that the receiving rate of hollow with water compound parabolic collector is changing slowly when incidence angle is increasing between 0 and 20°, and it can achieve 70% when the incidence angle less than 20°, and it is better than other concentrator with different cross section shapes. Based on simulation results, the experimental samples were processed and tested in a typical sunny weather. The experimental results were in good agreement with the simulation results. The system had a minimum transmittance of 28.2% at noon, but before 9:40 AM and after 15:40 PM, the transmittance exceeds 55% and can meet lighting requirements of rooms. It can be proved that the new system has passive light control function, which is expected to replace the double-layer vacuum glass curtain wall that is widely used nowadays.

[IEEE 2018 International Conference on Emerging Trends and Innovations In Engineering And Technological Research (ICETIETR) - Ernakulam (2018.7.11-2018.7.13)] 2018 International Conference on Emerging Trends and Innovations In Engineering And Technological Research (ICETIETR) - Density Based Traffic Control System Using Image Processing
摘要： In this paper, a novel real-time traffic control system which can easily keep traffic in control using image processing techniques is presented. In this method, a webcam is used in each stage of the traffic light in order to take pictures of the roads where traffic is bound to occur. Count of vehicles in these images is calculated using image processing tools in Matlab and different timings are allocated according to the count along with a green signal for vehicles to pass. In the proposed prototype, the green and red signals are represented using LEDs and the decrementing timer for the green signal is represented by a seven segment display.
