DR can be developed if one has Type 1 or Type 2 diabetes and a long history of uncontrolled high blood sugar levels. There are different forms of diabetic retinopathy such as non-proliferative Diabetic Retinopathy (NPDR), proliferative Diabetic Retinopathy (PDR) and Macular Edema (ME) [1] [2]. In case of NPDR blood vessels in the retina become week which results in Microaneurysms (MA), Haemorrhages (HA). While in case of PDR, areas of retina become oxygen deprived which leads to abnormal growth of blood vessels. Macular Edema represents the swelling of macula. Several parameters are associated with the growth of Diabetic Retinopathy [3] [4], such as, metabolism control density and genetic-constraint. During the primary phase, the arteries in retina begin to leak and minute haemorrhages are created [5] [6]. The vessels, which leaks from lipoprotei...

Machine translation is the process of automatically translating text or speech from one natural language into another. With rulebased, data-driven and hybrid-based techniques machine translation can be used to translate confidential documents, removal of language barrier in terms of education and learning, etc. Although various techniques for machine translation are proposed, but none of them is the state-of-the-art, which can be used effectively for every language. Thus in this paper, we aim to present a systemic literature review of the existing techniques for machine translation, along with some important issues in this domain. So that this paper may help in future research and in choosing an adequate technique for a particular purpose.

This is the limitation of conventional image retrieval system. To overcome this problem, we propose a new approach of extracting texture features for texture image retrieval by using a combined set of dual-tree rotated complex wavelet filter (DT-RCWF) and dual-tree-complex wavelet transform (DT-CWT) together, which obtains texture analysis in 12 different directions. A set of twodimensional (2-D) rotated complex wavelet filters (RCWFs) are designed with complex wavelet filter coefficients, which gives texture information strongly oriented in six different directions (450 apart from complex wavelet transform). The 2-D RCWFs are non-separable and oriented, which improves characterization of oriented textures. The information provided by DT-RCWF complements the information generated by DTCWT. Features are obtained by computing the...

Rapid changes in technology, low initial cost & planned obsolescence have resulted in fast growing surplus of electronic waste around the globe. The world produces about 40 millions tones of waste from electronic devices known as E-Waste. Large quantity of unused electronic waste causes serious pollution problem, environmental & health hazards because it contains some very serious contaminants such as CRTs, PCB, Silicon, Carbon, Arsenic, Cadmium, Mercury etc. but the e-waste also contains many valuable, recoverable materials such as aluminum, copper, gold, silver, plastic& tin. In order to conserve natural resources & the energy needed to produce new electronic equipment can be refurbished, reused & recycled instead of being land filled by tacking out the harmful contain from it.

One fundamental issue in today user wall(s) is to give users the ability to control the messages posted on their own private space to avoid that unwanted content is displayed. Up to now user walls provide little support to this requirement. To fill the gap, I propose a system allowing user wall users to have a direct control on the messages posted on their walls. This is achieved through a flexible rule-based system, that allows users to customize the filtering criteria to be applied to their walls, and Machine Learning based soft classifier automatically labeling messages in support of content-based filtering.

Research paper thumbnail of Design of Digital Modulators: BASK, BPSK and BFSK using VHDL

Digital modulation is less complex, more secure and more efficient in long distance transmission.... more Digital modulation is less complex, more secure and more efficient in long distance transmission. The noise detection and correction in digital is more efficient than analog counterpart. So it has more importance in modern communication. Digital modulation represents the transfer of the digital bit stream from the transmitter to the receiver via the analog channels. During the modulation process the information signal modifies one or more carrier parameters, leading to shift keying techniques. A very widespread solution is the Software Defined Radio (SDR), whose modulation/demodulation methodology consists in programming either software in a dedicated processor (DSP), or logic in a programmable logic device (FPGA). These digital modulation techniques can be realized using FPGA (Field- programmable gate-array). In literature survey found that design employs the minimum number of blocks necessary for achieving BASK, BPSK and BFSK modulation. The modulating and carrier signals can be u...

The ease of control and excellent performance of the DC motors will ensure that the number of applications using them will continue to grow for the foreseeable future. In this paper, a method to control the speed of DC motor using Pulse Width Modulation (PWM) is explained. PWM is generated using Microcontroller 8051. To drive the motor, H-bridge is used which is made up of four MOSFETs. Precise control of low torque DC motor is obtained by using simple and inexpensive hardware. This paper shows that accurate and precise control of small DC motors can be done effectively and efficiently without using complicated circuitry and costly components.

In order to implement the any speech application in Altera DE2 board a controller is designed to control the CODEC and acquire the digital data from it. This paper presents an experimental design and implementation of the controller using the specification given by the Philips for I2C protocol & DSP mode of operation of CODEC on cyclone-II EP2C35F72C6 FPGA in Altera DE2 board. A controller was designed using VHDL language, which performs the two operations: I2C protocol operation to drive the Wolfson Codec WM8731, sound fetching from W olfson Codec WM8731 to FPGA in DSP mode. Altera Quartus II 9.0 sp2 web Edition is used for the synthesis of the VHDL logic on FPGA and ModelSim-Altera 6.5b (Quartus II 9.1) Starter Edition is used for the simulation of VHDL logic. Three modules have been created in the design: the I2C bus controller, virtual sound fetcher, and the clock module. The FPGA communicates with the Wolfson via the I2C (Inter-Integrated Circuit) protocol using two pins: 'SDIN' (the data line), and 'SCLK' (the bus clock). I2C bus controller modifies internal settings of Codec, de-mute the microphone input, boost the microphone volume, and change the default sound path (so that the microphone is given priority over other inputs). After the codec digitalizes the input it put the digital data on digital audio interface, to fetch the data on DACDAT of codec form digital audio interface DSP mode of operation of codec is used in the design. DACDAT is the formatted digital audio data stream with left and right channels multiplexed together. DACLRC (alignment clock) and BCLK (synchronization clock) is used to fetch the data on DACDAT this data can be use for any sound application. Clock module is design to generate different clock requirem ent for the controller.

Drainage water management is the practice of raising the drainage outlet during times of the year when drainage is not needed or a higher water table could benefit the crop. Drainage water management allows producers to have more control over drainage. In this paper, we tried to build a project or system based on FPGA which is going to help drainage management for smart cities. As we have seen unless and otherwise drainage system is properly maintained the dream of Smart City remains as dream. Proposed system is prototype, implemented on Altera FPGA Development Board using VHDL.
