the notion of absorbent ordered filters in implicative semigroupsis introduced, and its fuzzification is considered. relations among (fuzzy) orderedfilters, (fuzzy) absorbent ordered filters, and (fuzzy) positive implicativeordered filters are stated. the extensionproperty for (fuzzy) absorbent orderedfilters is established. conditions for (fuzzy) ordered filters to be (fuzzy)absorbent ordered ...

Large, high-resolution displays (LHRD) are capable of visualizing a large amount of very detailed information but also introduce new challenges for human-computer interaction. Besides potential information overload and disorientation, limited visual acuity and field of view force users to physically move around in front of these displays to perceive either object details or an overview. However...

In this paper, a current-mode Kerwin-Huelsman-Newcomb (KHN) filter structure employing four z-copy current follower transconductance amplifiers (ZC-CFTAs) and two grounded capacitors is proposed. The circuit structure has one low-impedance current input and three high-impedance current outputs and enables realizing lowpass, bandpass and highpass current responses simultaneously. The bandstop an...

Since its introduction in 1960, the Kalman filter has become an integral component in thousands of military and civilian navigation systems. This deceptively simple, recursive digital algorithm has been an early-on favorite for conveniently integrating (or fusing) navigation sensor data to achieve optimal overall system performance. To provide current estimates of the system variables -such as ...

This paper describes development of adaptive filter algorithm for an Underwater Acoustic Telemetry (UWAT) system for communication between the off shore underwater device (UD) and on-shore communication system. In this system, FSK modulation and de-modulation techniques are used with centre frequency of 38 KHz with baud rate of 300Hz. Adaptive filter algorithm has been developed to compensate t...

High definition Video (HDV) is increasingly becoming common feature in video display devices as it provides superior level of details in comparison to standard video. Latest video compression standard, H.264/AVC can be used for storage and efficient transmission over network. However, blocking artifacts are introduced due to loss of correlation between blocks during compression process. H.264/A...

By first principle calculations, a dual spin filter effect under finite bias voltages is demonstrated in an antiferromagnetic junction of symmetric zigzag graphene nanoribbon (ZGNR). Unlike conventional spin filter devices using half metallic materials, the upand down-spin electrons are unidirectionally filtered in the counter direction of the bias voltage, making the junction a dual spin filte...

The paper introduces designing of MAC 20 tap IIR filter based on Field Programmable Gate Array (FPGA).The implementation is based on Multiply Add and Accumulate algorithm (MAC) unit which plays important role in many of the DSP aplications.MAC unit is used for best performance digital signal processing system. The designed filter has been synthesized on Digital Signal Processor (DSP) slice base...
