A Digital Imaging Workflow for TEM Using a Low Cost Scanner

Computer Network Time Synchronization using a Low Cost GPS Engine

Accurate and reliable time is necessary for financial and legal transactions, transportation, distribution systems, and many other applications. Time synchronization protocols such as NTP (the Network Time Protocol) have kept clocks of such applications synchronized to each other for many years. Nowadays there are many commercial GPS based NTP time server products at the market but they almost ...

Digital Breast Imaging Workflow.

Most breast imaging programs have replaced film-screen mammography systems with digital mammography. Other breast imaging methods, such as digital breast tomosynthesis, complement the tools available for screening and diagnosis of breast cancer. This article examines digital mammography, other digital breast imaging modalities, and the effects of these technologies on practice, quality, efficie...

Column operation studies for the removal of dyes and phenols using a low cost adsorbent

Fertilizer plant waste carbon slurry has been investigated after some processing as an adsorbent for the removal of dyes and phenols using columns. The results show that the carbonaceous adsorbent prepared from carbon slurry being porous and having appreciable surface area (380 m2/g) can remove dyes both cationic (meldola blue, methylene blue, chrysoidine G, crystal violet) as well a...

Cloud Base Height Estimation Using a Low-cost Digital Camera

 Cloud height, wind speed and direction at cloud height play an important role in air safety. This paper presents a low-cost system based on digital consumer cameras to estimate cloud base height. It is shown that both wind speed and direction at cloud level can also be obtained with this system. The method is based on triangulation and uses image registration to identify common cloud features...
