# A Binary Images Watermarking Algorithm Based on Adaptable by Zhang Fan, Zhang Junliang

By Zhang Fan, Zhang Junliang

A watermarking set of rules of binary pictures utilizing adaptable matrix is gifted. An adaptable matrix is designed to guage the smoothness and the connectivity of binary photographs. The watermark is embedded in accordance with the adaptable matrix during this set of rules. within the proposed watermarking set of rules, each one picture block implements a XOR operation with the binary adaptable matrix, which has a similar dimension with the picture block, and in an effort to embed the watermark info, a multiplication operation also are carried out with the load matrix. The experimental effects convey that proposed scheme has an outstanding functionality.

The Irrationals: A Story of the Numbers You Can't Count On

The traditional Greeks came upon them, however it wasn't until eventually the 19th century that irrational numbers have been accurately understood and carefully outlined, or even this present day now not all their mysteries were published. within the Irrationals, the 1st well known and complete publication at the topic, Julian Havil tells the tale of irrational numbers and the mathematicians who've tackled their demanding situations, from antiquity to the twenty-first century.

In mathematical circles. Quadrants I, II (MAA 2003)

For a few years, famed arithmetic historian and grasp instructor Howard Eves gathered tales and anecdotes approximately arithmetic and mathematicians, accumulating them jointly in six Mathematical Circles books. hundreds of thousands of lecturers of arithmetic have learn those tales and anecdotes for his or her personal entertainment and used them within the school room - so as to add leisure, to introduce a human point, to encourage the coed, and to forge a few hyperlinks of cultural heritage.

Mathematics of Digital Images: Creation, Compression, Restoration, Recognition

This significant revision of the author's renowned publication nonetheless specializes in foundations and proofs, yet now shows a shift clear of Topology to chance and data conception (with Shannon's resource and channel encoding theorems) that are used all through. 3 very important parts for the electronic revolution are tackled (compression, recovery and recognition), developing not just what's actual, yet why, to facilitate schooling and learn.

Mathe ist doof !? Weshalb ganz vernünftige Menschen manchmal an Mathematik verzweifeln

Viele Menschen haben den Seufzer "Mathe ist doof! " schon ausgestoßen. Sind denn alle diese Leute dumm oder "mathematisch unbegabt"? Wie kaum ein anderes Fach spaltet Mathematik die Geister: Mathematik ist schön, ästhetisch, wunderbar logisch und überaus nützlich - sagen die einen. Die anderen empfinden Mathematik als eine dröge Quälerei mit abstrakten Symbolen und undurchsichtigen Formeln, die guy irgendwie in der Schule durchstehen muss - und dann vergessen kann.

A unique characteristic of a rooftop VAV system, however, is that the same piece of hardware that provides the unit-level control functions for the packaged rooftop air conditioner can also perform many of these system-level control functions. TRG-TRC017-EN 35 period two Automatic Control of HVAC Systems notes Air-Cooled Chiller, Fan-Coil System dedicated outdooroutdoor-air unit fanfan-coil units airair-cooled chiller systemsystem-level controller pumps boiler Figure 43 The third example system includes fan-coil units served by an air-cooled chiller and boiler.

During cold weather, this is called the “morning warm-up” mode. For this example rooftop VAV system, each VAV terminal unit is fully opened. The rooftop unit turns on the supply fan, closes the outdoor-air damper, and heats the recirculated return air. As a zone reaches the occupied setpoint, the corresponding VAV terminal unit closes. The supply fan modulates its capacity until all zones (or a single, representative zone) have reached their occupied setpoints. Just like the example chilled-water VAV system, coordinating the operation of the VAV terminal units and the rooftop unit during these different operating modes is one of the functions provided by the system-level controller.

TRG-TRC017-EN 49 period three Building Automation Systems notes Graphical User Interface Figure 58 Graphical representations of the HVAC equipment and systems often make it easier to navigate the system when investigating problems. This is because the graphics on the screen mimic what the operator knows to be installed on the roof, in the equipment rooms, and in the ceilings. This example shows a VAV air handler similar to the one described in Period Two. The use of graphics provides a logical organization for the many pieces of data available for this equipment.
