Analysis Of 3d Cone-Beam Ct Image Reconstruction Performance On A Fpga, Devin Held 2016 The University of Western Ontario

Analysis Of 3d Cone-Beam Ct Image Reconstruction Performance On A Fpga, Devin Held

Electronic Thesis and Dissertation Repository

Efficient and accurate tomographic image reconstruction has been an intensive topic of research due to the increasing everyday usage in areas such as radiology, biology, and materials science. Computed tomography (CT) scans are used to analyze internal structures through capture of x-ray images. Cone-beam CT scans project a cone-shaped x-ray to capture 2D image data from a single focal point, rotating around the object. CT scans are prone to multiple artifacts, including motion blur, streaks, and pixel irregularities, therefore must be run through image reconstruction software to reduce visual artifacts. The most common algorithm used is the Feldkamp, Davis, and ...

The binary addition is the basic arithmetic operation in digital circuits and it became essential in most of the digital systems including ALU, microprocessors and DSP. Adders are the basic building blocks in digital integrated circuit based designs. Ripple Carry Adder (RCA) gives the most compact design but takes longer computation time. The time critical applications use Carry Look-ahead scheme (CLA) to derive fast results but they lead to increase in area. Carry Select Adder is a compromise between RCA and CLA in term of area and delay. This paper focuses on the design analysis of carry select adder based ...

The circuit used to add the two numbers or two bits is adder. The main problem with the adder is both the area and delay to produce the final output. So, this paper implements an adder it requires a less amount of delay and area to produce the final output. The reduction of delay and area is done by the Parallel Prefix Adders. It plays a prominent role in Digital Combinational Circuits. Area and power are other factors which really makes the adder effective. The techniques used to get a less amount of delay and area is by using the ...


Studying The Effects Of Serpentine Soil On Adapted And Non-Adapted Species Using Arduino Technology, Kiana Saniee, Edward Himelblau, Brian Paavo 2016 California Polytechnic State University - San Luis Obispo

Studying The Effects Of Serpentine Soil On Adapted And Non-Adapted Species Using Arduino Technology, Kiana Saniee, Edward Himelblau, Brian Paavo

STAR (STEM Teacher and Researcher) Presentations

Abstract: Serpentine soils are formed from ultramafic rocks and are represent an extreme environment for plants. Serpentine soils are unique in that they carry high concentrations of heavy metals, are nutrient deficient, particularly in calcium, and have poor water retention capabilities. Although these soils constitute harsh conditions for plant growth, there are a number of species that are adapted and even endemic to serpentine soil. Water retention by commercial potting mix was compared with serpentine soil. Also, serpentine adapted and non-adapted species were grown in both soil treatments and physiological data were collected. We used the Arduino electronic platform to ...


Mechanical Design And Optimization Of An Interactive Animatronic Bald Eagle, Eric Burns 2016 Georgia Southern University

Mechanical Design And Optimization Of An Interactive Animatronic Bald Eagle, Eric Burns

Phi Kappa Phi Research Symposium

Animatronics is a specialized sub-category of mechatronics, a fusion of mechanical and electrical engineering. The field has grown from small, individual projects into a major industry. As animatronics progress, mechanical engineers are pushed to design internal structures which occupy ever-decreasing spaces and to ensure designs can undergo maintenance and modifications smoothly. This research investigates methods of reducing space required for mechanisms and several other beneficial methods of development as well as varying satisfactions for audiences when exposed to actor-controlled systems rather than pre-scripted functions. The mechanical systems are designed using CAD software available at Georgia Southern. On-campus, resources are used ...

Various approaches and designs of digital arithmetic units have been proposed in the recent years and their merits and demerits have been compared on various performance parameters. In modern day digital systems, Arithmetic and Logic Unit operations on reconfigurable devices are the most important area of research. In this paper, a novel design for Carry Select Adder is proposed. In the design, the half adder of both the ripple carry adders is shared and an initial sum and carry is generated. The carry input module generates the ‘carry’ values and are passed through multiplexer in first method or xor-ed with ...

Comparison Of 32-Bit Hybrid Adders In Vhdl, Viraj V. Gotmare, Pankaj Agrawal

Kirat Pal Singh

This paper describes the comparison between the hybrid adders. Adders are always used in many data-processing systems to perform fast arithmetic operations. The carry select adder (CSA) is a high speed adder. It provides good compromise between RCA and CLA. The ripple carry adder (RCA) has a most compact design but it takes longer computation time. The time critical applications uses carry look-ahead adder (CLA) to derive fast result but it required a large area. In this work we compared hybrid adders on the basis of delay, power and area. This design has been synthesized by Spartan 3 family with ...

El Capitán: Cal Poly Rose Float Digital Drive System, Gregory Raffi Baghdikian

Computer Engineering

In today’s world of smartphones, self-driving cars, and internet-connected coffee makers, it seems as if computers are contained in everything around us. These “embedded systems” have become critical components of our lives, improving everything about the things they control, from cost, to speed, to simplicity. One area that embedded systems has hardly gained a foothold is in the world of floatbuilding. Most of the floats in the Tournament of Roses Parade, including the one built jointly by Cal Poly San Luis Obispo and Cal Poly Pomona, are technologically very simple, using mostly analog components and rudimentary discrete digital logic ...

Stand, Lisa Yip

Computer Engineering

With busy lives, people sometimes forget to take breaks for multiple hours at a time. The purpose of this project is to remind the user to move around every hour if they have not already. To do so, stand will be a light weight fitness tracker that will detect the number of steps made within an hour. If the step count, dependent on goals, is not met then a vibration motor will gently remind them to take a break and walk. The data throughout the day will be shown on an iOS application where the user will be able to ...
