Insufficient visibility in bad climate condition due to haze and fog is a foremost problem in an outdoor image. Thus, fog removal from image and video is required for getting high performance of the vision algorithm. In this thesis, we propose a simple but effective method using dark channel estimation, atmospheric light estimation, transmission estimation, scene radiance recovery to remove haz...

During the last decade, Cloud computing has efficiently exploited the economy of scale by providing low cost computational and storage resources over the Internet, eventually leading to consolidation of computing resources into large data centers. However, the nascent of the highly decentralized Internet of Things (IoT) technologies that cannot effectively utilize the centralized Cloud infrastr...

The transcription factors that control lineage specification of haematopoietic stem cells (HSCs) have been well described for the myeloid and lymphoid lineages, whereas transcriptional control of erythroid (E) and megakaryocytic (Mk) fate is less understood. We here use conditional removal of the GATA-1 and FOG-1 transcription factors to identify FOG-1 as required for the formation of all commi...

The global cell movements that shape an embryo are driven by intricate changes to the cytoarchitecture of individual cells. In a developing embryo, these changes are controlled by patterning genes that confer cell identity. However, little is known about how patterning genes influence cytoarchitecture to drive changes in cell shape. In this paper, we analyze the function of the folded gastrulat...

The wide spread of food outlets has become an environmental and sanitation infrastructure problem, due to Fats, Oils and Grease (FOG). A grease box is used at the industrials facilities to collect the FOG, in a specific time window, while its quality is good for recycling (e.g., biodiesel) and it is economically valuable. After this period, it will be disposed at a cost. For the proper manageme...

A GROWING NUMBER OF COMputer-vision systems have emerged for traffic analysis and control. Increased traffic, along with steady efforts to improve driver security, have encouraged the development of sophisticated video-based systems, providing statistical measures of traffic flow for actual traffic information on variable message signs. Investigations show that VMS reduce traffic jams, thus min...

In Finland fogging in mine ramps is a common problem. Fog forms when warm and humid exhaust air moves upwards the ramp, where the skin temperature of surrounding wallrock decreases to about 10°C. Changes in fog thickness and lengths of fog-filled parts of the ramp depend at least on climatic conditions outside, diesel equipment usage in the mine, and the length of working sequence at a time. In...

MicroRNAs are increasingly being recognized as regulators of embryonic development; however, relatively few microRNAs have been identified to regulate cardiac development. FOG-2 (also known as zfpm2) is a transcriptional co-factor that we have previously shown is critical for cardiac development. In this report, we demonstrate that FOG-2 expression is controlled at the translational level by mi...

W ea th er – Ju ly 20 10 , V ol . 6 5, N o. 7 fog, but the north tower had a story to tell. It worked as a chimney. The fog entered and escaped through the openings of the tower, displaying iridescent colors and creating ever-changing and fast-moving fog shadows of the tower and the cables (Figure 2). I emailed a few images to Dr Andrew T. Young at the Astronomy Department, San Diego State Univ...

Many processes interact in a complex and highly non-linear way during the life cycle of fog, the turbulent transport being among them. Observations and analysis of turbulence are, then, fundamental to our understanding of the physical mechanisms involved with fog formation, evolution and dissipation. Data gathered by fast-response sonic anemometers are processed using wavelet methods in order t...
