Motor Temperature Monitoring Based on Impedance Estimation at PWM Frequencies

This paper proposes a noninvasive temperature measurement technique of indirect type, applicable in the permanent magnet synchronous motor (PMSM) drives. The motor temperature is required for protection and monitoring purposes, as well as for updating temperature-dependent control parameters. Direct measurement with dedicated sensors requires peripherals and cabling; hence, it is quite involve…

A Robotic Crack Inspection and Mapping System for Bridge Deck Maintenance

One of the important tasks for bridge maintenance is bridge deck crack inspection. Traditionally, a human inspector detects cracks using his/her eyes and marks the location of cracks manually. However, the accuracy of the inspection result is low due to the subjective nature of human judgement. We propose a crack inspection system that uses a camera-equipped mobile robot to collect images on th…

Beam Search Combined With MAX-MIN Ant Systems and Benchmarking Data Tests for…

In real-world cargo transportation, there are charges associated with both the traveling distance and the loading quantity. Cargo trucks must comply with a mandatory lower carbon emissions policy: the emissions of large-volume cargo truck/containers depend greatly on the cargo loading and the traveling distance. To address this issue, instead of assuming a constant vehicle loading from one cust…

Performance and Limitations of a Constant Power-Fed Supercapacitor

Analytical description of a constant power fed supercapacitor behavior is revealed in the paper. The derivation is based on a simple RC model with parameters taken from a manufacturer datasheet. Different power and energy-related figures of merit are obtained using the derived expressions. It is shown that some of the performance figures used in datasheets are strictly theoretical and cannot be…

In addition, the proposed algori…

The ability to detect changes is an essential competence that robots should possess for increased autonomy. In several applications, such as surveillance, a robot needs to detect relevant changes in the environment by comparing current sensory data with previously acquired information from the environment. We present an efficientmethod for point cloud comparison and change detection in 3D envir…

Data Acquisition for Probabilistic Nearest-Neighbor Query

Management of uncertain data in spatial queries has drawn extensive research interests to consider the granularity of devices and noises in the collection and the delivery of data. Most previous works usually model and handle uncertain data to find the required results directly. However, it is more difficult for users to obtain useful insights when data uncertainty dramatically increases. In th…

A Robust Surface Coding Method for Optically Challenging Objects Using Struct…

Though the structured light measurement system has been successfully applied to the profilemeasurement of diffuse objects, it is still a challenge to measure shiny objects due to the mix of both specular and diffuse reflections. To this end, we propose a robust encoding and decoding method in this paper. First, the monochromatic stripe patterns are utilized to eliminate the effect of texture an…

Transformation-Based Monetary Cost Optimizations for Workflows in the Cloud

Recently, performance and monetary cost optimizations for workflows from various applications in the cloud have become a hot research topic. However, we find that most existing studies adopt ad hoc optimization strategies, which fail to capture the key optimization opportunities for different workloads and cloud offerings (e.g., virtual machines with different prices). This paper proposes ToF, …

Civil engineering reference manual for the pe exam

As I mentioned in the preface to the thirteenth edition, I am chagrined to admit that I never read a single preface while I was in college. Out of the prefaces of 100 or so textbooks written by witty, clever, dedicated, and famous experts, I never read a single word. Since then, I’ve added hundreds of additional books to my library, and I’ve only read a few of their prefaces. I certainly ha…

Civil Engineering for Underground Rail Transport

Thirty-five years ago Bill Cassie (Professor William Fisher Cassie) used to tell his students in Newcastle that one of the tasks of civil engineers was to put services under the ground, including transport. The surface was for people on foot and, in future, the movement of vehicles would be underneath towns, as with the movement of water and sewage. He was ahead of his time; he had writt…

Chemical Grouting and Soil Stabilization

Over a decade has passed since publication of the second edition. During this time the major changes have been the movement of chemical grouting from remedial use to preventive use, and the development and growing use of other methods of ground improvement. Although new grouts have been developed, silicates and acrylics still dominate the domestic market. Increasing sophistication in grouting e…

Analyzing Uncertainty in Civil Engineering

This volume addresses the issue of uncertainty in civil engineering from design to construction. Failures do occur in practice. Attributing them to a residual risk or a faulty execution of the project does not properly cover the range of causes. A closer scrutiny of the design, the engineering model, the data, the soil-structure-interaction and the model assumptions is required. Usually, th…

Advanced civil infrastructure materials

Concrete and steel are by far the most widely used man-made construction materials in the world. Despite numerous successful constructions of worldwide infrastructures, many of these infrastructures are now rapidly deteriorating. It has been estimated that infrastructure rehabilitation costs, in the US alone, will reach into trillions of dollars over the next twenty years. One of the prima…

Indexing Graphs for Path Queries with Applications in Genome Research

We propose a generic approach to replace the canonical sequence representation of genomes with graph representations, and study several applications of such extensions. We extend the Burrows-Wheeler transform (BWT) of strings to acyclic directed labeled graphs, to support path queries as an extension to substring searching. We develop, apply, and tailor this technique to a) read alignment on an…

Furthermore, the analog/RF performance evaluation and linearity distortion analysis due to the interface trap charges in terms of figure-of-merit metrics, i.e., drain cur…

Engineering mechanics of solids (College custom series)

This is a book about the Mechanics of Solids, Statics, the Strength of Materials, and Elasticity Theory. But that doesn’t mean a thing unless you have had a course in the Mechanics of Solids, Statics, the Strength of Materials, or Elasticity Theory. I assume you have not; let us try again: This is a book that builds upon what you were supposed to learn in your basic physics and mathematics…

Introduction To Physical Oceanography

This book is written for upper-division undergraduates and new graduate students in meteorology, ocean engineering, and oceanography. Because these students have a diverse background, I have emphasized ideas and concepts more than mathematical derivations.

This paper proposes a new modulation strategy that balances the neutral-point voltage for three-level neutral-clamped inverter systems. The proposed modulation replaces the P-type or N-type small switching states with other switching states that do not affect the neutral-point voltage. The zero and medium switching states are employed to help the neutral-point voltage balancing. This method lit…

Thermal-Aware Scheduling of Batch Jobs in Geographically Distributed Data Cen…

Decreasing the soaring energy cost is imperative in large data centers. Meanwhile, limited computational resources need to be fairly allocated among different organizations. Latency is another major concern for resource management. Nevertheless, energy cost, resource allocation fairness, and latency are important but often contradicting metrics on scheduling data center workloads. Moreover, wit…

An Odd Parity Checker Prototype Using DNAzyme Finite State Machine

A finite-state machine (FSM) is an abstract mathematical model of computation used to design both computer programs and sequential logic circuits. Considered as an abstract model of computation, FSM is weak; it has less computational power than some other models of computation such as the Turing machine. This paper discusses the finite-state automata based on Deoxyribonucleic Acid (DNA) and dif…
