Technology Dependency

Discrete Cosine Transform (DCT) is commonly used in image compression. In the history of DCT, a milestone was the Distributed Arithmetic (DA) technique. Due to the technology dependency a multiplier-less computation was built with DA based technique. It occupied less area but the throughput is less. Later, due to the technology scaling, multiplier based architectures can be easily adapted for low-power and high-performance architecture. Fixed width multipliers [1]-[7] reduces hardware and time complexity. In this work, Radix 4 fixed width multiplier is adapted with DCT architecture due to low power consumption and saves 30% power. In order to reduce truncation errors caused during fixed width multiplication, an estimation circuit is designed based on conditional probability theory.

Switching Temperature

Thermally induced switching temperature and spectral transmittance of a novel kind of smart thermotropic material developed by a different mixing proportion of hydroxypropyl methyl cellulose (HPMC), sodium chloride ( NaCl ) and pure water was measured. Radiation transmittance measurements were carried out on a thermotropic double glazing window sample, a double glazing window and a low-E double glazing window. Results show that the thermotropic double-glazed window with optimum mixing proportion of HPMC, NaCl and pure water of 2:10:100 by mass-reduces radiation transmittance at fully turbid state by up to 72% and 32% respectively, compared to the ordinary double-glazed window and low-E double-glazed window which do not have adjustable radiation transmittance; its radiation transmittance changed from transparent state to light scattering state up to 60%, indicating a high performance on switching solar radiation and a great potential for energy efficient windows.
