Attacker-Induced Traffic Flow Instability In A Stream Of Automated Vehicles, Daniel D. Dunn 2015 Utah State University

Attacker-Induced Traffic Flow Instability In A Stream Of Automated Vehicles, Daniel D. Dunn

All Graduate Theses and Dissertations

Highway systems world wide continue to see an ever increased number of vehicles and subsequently a rise in congested traffic. This results in longer commute times, wasted energy as vehicles idle in stop and go traffic, and increases the risk of accidents. In short, increased congestion costs time and money. These issues have prompted much research into Automated Highway Systems (AHS). In AHS vehicles using computer algorithms can safely travel at much smaller inter-vehicle distances than human drivers are capable of. This increases the capacity of existing highway systems. Sensors aboard each vehicle make this possible by monitoring their surroundings ...

Implementation Of Regular Linear Carry Select Adder With Binary To Excess-1 Converter, K. Bala Sindhuri

Innovative Research Publications IRP India

Regular Linear Carry Select Adder (RCSLA) is one of the fastest adders. From the structure of RCSLA, there is scope to reduce area by using Binary to Excess-1 converter (BEC) technique. By using BEC technique in RCSLA 16, 32, 64 bit architectures have been developed and compared with Regular Linear Carry Select Adder. The modified architectures have reduced area and power with slight increase in delay. Simulation and Synthesis are carried on Xilinx ISE 12.2.The result analysis shows that the modified architectures are better than RCSLA.

Numax: A Convex Approach For Learning Near-Isometric Linear Embeddings, Chinmay Hegde, Aswin C. Sankaranarayanan, Wotao Yin, Richard G. Baraniuk

Department of Electrical and Computer Engineering

We propose a novel framework for the deterministic construction of linear, near-isometric embeddingsof a finite set of data points. Given a set of training points X RN, we consider the secant set S(X) that consists of all pairwise difference vectors of X, normalized to lie on the unit sphere. We formulate an affine rank minimization problem to construct a matrix that preserves the norms of all the vectors in S(X) up to a distortion parameter . While affine rank minimization is NP-hard, we show that this problem can be relaxed to a convex formulation that can be solved using ...

Renewable Energy In Industrial Applications, Seshi Reddy Kasu 2015 Kennesaw State University

Renewable Energy In Industrial Applications, Seshi Reddy Kasu

Dissertations, Theses and Capstone Projects

Manufacturing industry accounts for about one third of total energy use worldwide. Roughly three quarters of industrial energy use is related to the production of energy-intensive commodities such as ferrous and non-ferrous metals, chemicals and petrochemicals, non-metallic mineral materials, and pulp and paper. In these sectors, energy costs constitute a large proportion of total production costs, so managers pay particular attention to driving them down. As a result, the scope to improve energy efficiency tends to be less in these most energy intensive sectors than in those sectors where energy costs form a smaller proportion of total costs, such as ...

Non-Linear Chirp Spread Spectrum Communication Systems Of Binary Orthogonal Keying Mode, Quan Wang 2015 The University of Western Ontario

Non-Linear Chirp Spread Spectrum Communication Systems Of Binary Orthogonal Keying Mode, Quan Wang

University of Western Ontario - Electronic Thesis and Dissertation Repository

Chirp spread spectrum (CSS) is a suitable choice of modulation signals for wireless communications, due to its inherited advantages such as low transmission power, simplicity of implementation, good interference rejection capability. Linear chirps are common choices in practical CSS systems of binary orthogonal keying (BOK) mode. However, linear chirps generally require the time-bandwidth product of each chirp signal to be 60 sHz or more in order to achieve desirable orthogonality requirements. Thus, a BOK CSS system based on linear chirps has to occupy very wide bandwidth, which is a very precious resource for wireless communication. Clearly, the requirement on broad ...

Hybrid Power Generation Systems: A Holistic View, Almoataz Youssef Abdelaziz

Almoataz Youssef Abdelaziz

The importance of the hybrid power generation systems (HPGS) increased especially in the last few years. HPGS are used to share the load with the utility grid and these systems are termed as HPGS-utility grid. In addition, they are used to transmit the power to the remote areas. In this case, these systems are termed as stand-alone HPGS. HPGS consist of different power sources such as photovoltaic systems (PV), wind turbine (WT), micro-turbine (MT), storage battery (SB), diesel generator, and fuel cell (FC). These sources are considered the prominent elements. The importance of the HPGS can be carried out via ...

Transformer is a soul of both transmission and distribution systems. It performs low voltage to high voltage conversion in transmission lines and similarly high voltage to low voltage conversion in distribution lines. The operation of transformer is decided by the cooling provided to the system. The efficient cooling method is achieved by the use of forced (or) natural oil cooling medium. The oils used for the purpose of coolants are the hydrocarbons of paraffin (or) naphtha based petroleum products. The oil is used as coolant is made from highly refined mineral oil and it has high dielectric strength. During the ...
