An Approach To Solve Job Shop Scheduling Problem, Shashidhar Reddy Karnati
An Approach To Solve Job Shop Scheduling Problem, Shashidhar Reddy Karnati
Master's Projects
“A biotechnology device manufacturer needs to devise effective scheduling algorithms for its testing devices. A device is a configuration of machines, each of which performs a specific task, such as washing, reading and cleaning. These devices are used to test human samples to diagnose diseases like cholera, malaria etc. Each test is a job, which is to be processed on these machines for a specific amount of time. Every job has its own pre defined sequence. These samples are to be processed simultaneously on machines owing to constraint that as soon as one machine completes processing a sample, it should …

Master's Projects
Correspondence through email has become a very significant way of communication at workplaces. Information of most kinds such as text, video and audio can be shared through email, the most common being text. With confidential data being easily sharable through this method most companies monitor the emails, thus invading the privacy of employees. To avoid secret information from being disclosed it can be encrypted. Encryption hides the data effectively but this makes the data look important and hence prone to attacks to decrypt the information. It also makes it obvious that there is secret information being transferred. The most effective …
An Evaluation Of The X10 Programming Language, Xiu Guo
An Evaluation Of The X10 Programming Language, Xiu Guo
Master's Projects
As predicted by Moore's law, the number of transistors on a chip has been doubled approximately every two years. As miraculous as it sounds, for many years, the extra transistors have massively benefited the whole computer industry, by using the extra transistors to increase CPU clock speed, thus boosting performance. However, due to heat wall and power constraints, the clock speed cannot be increased limitlessly. Hardware vendors now have to take another path other than increasing clock speed, which is to utilize the transistors to increase the number of processor cores on each chip. This hardware structural change presents inevitable …
Eigenvalue Analysis For Metamorphic Detection, Sayali Deshpande
Eigenvalue Analysis For Metamorphic Detection, Sayali Deshpande
Master's Projects
Metamorphic viruses change their structure on each infection while maintaining their function. Although many detection techniques have been proposed, practical and effective metamorphic detection remains a difficult challenge. In this project, we analyze a novel method for detecting metamorphic viruses. Our approach was inspired by a well-known facial recognition technique that is based on eigenvalue analysis. We compute eigenvectors using opcode sequences extracted from a set of known metamorphic viruses. These eigenvectors can then be used to score a given executable file, based on its extracted opcode sequence. We perform extensive testing to determine the effectiveness of this scoring technique …

Semantic Discovery Through Text Processing, Bieu Binh Do
Master's Projects
As the world embraces the digital era, unprecedented volumes of information are generated and consumed daily. It becomes difficult to comb through mountains of documents to locate search topics. With inherent ambiguity in human languages, conventional methods using straight text pattern match cannot resolve words having multiple meanings and often misinterpret user intent. There is a need to develop a system able to identify the target topic and return quality relevant links, ending the tedium of rummaging through piles of unrelated links that may get lost in the rubble. An example search of the words “sound investment” helps to illustrate …
Structural Entropy And Metamorphic Malware, Donabelle Baysa
Structural Entropy And Metamorphic Malware, Donabelle Baysa
Master's Projects
Metamorphic malware is capable of changing its internal structure without al- tering its functionality. A common signature is nonexistent in highly metamorphic malware. Consequently, such malware may remain undetected even under emulation and signature scanning combined. In this project, we use the concept of structural entropy to analyze variations in the complexity of data within a file. The process consists of two stages, namely, file segmentation and sequence comparison. In the file segmentation stage, we use entropy measurements and wavelet analysis to segment a file. The second stage measures the similarity of files by computing the edit distance between sequence …
Video In The Cloud Tcp Congestion Control Optimization For Cloud Computing, Rafael Alvarez-Horine
Video In The Cloud Tcp Congestion Control Optimization For Cloud Computing, Rafael Alvarez-Horine
Master's Projects
With the popularity of video streaming, a new type of media player has been created called the adaptive video player that adjusts video quality based on available network bandwidth. Merging this technology with cloud computing will change the online video landscape by allowing providers to dynamically create media servers that take advantage of all the benefits of cloud computing. This however is not a straightforward endeavor as unlike a traditional data center; a cloud-based infrastructure is subject to a greater amount of performance variability. While the adaptive video player is designed to cope with variability in general, a video server …
A Database-Driven Website Of Β-Thalassemia Mutations, Vanessa Gaeke
A Database-Driven Website Of Β-Thalassemia Mutations, Vanessa Gaeke
Master's Projects
β-thalassemia is a genetic disease caused by mutations of the hemoglobin gene β (HBB). Over two hundred β-thalassemia mutations are known to date. While the pathological consequence of each β-thalassemia mutation has been well documented, the effect of a mutation at the molecular level of its DNA sequence is usually not illustrated for beginners. This paper describes the cause of β-thalassemia and a database-driven website containing mutant HBB sequences altered by β-thalassemia mutations. β-thalassemia mutations and their relevant data are first collected from the HbVar Database of Pennsylvania State University and loaded into a PostgreSQL database. Wild type HBB sequences …

Hierarchical Clustering Using Level Sets, Francesco Indaco
Hierarchical Clustering Using Level Sets, Francesco Indaco
Master's Projects
Over the past several decades, clustering algorithms have earned their place as a go-to solution for database mining. This paper introduces a new concept which is used to develop a new recursive version of DBSCAN that can successfully perform hierarchical clustering, called Level- Set Clustering (LSC). A level-set is a subset of points of a data-set whose densities are greater than some threshold, ‘t’. By graphing the size of each level-set against its respective ‘t,’ indents are produced in the line graph which correspond to clusters in the data-set, as the points in a cluster have very similar densities. This …

Although massively parallel sequencing has facilitated large-scale DNA sequencing, comparisons among distantly related species rely upon small portions of the genome that are easily aligned. Methods are needed to efficiently obtain comparable DNA fragments prior to massively parallel sequencing, particularly for biologists working with non-model organisms. We introduce a new class of molecular marker, anchored by ultraconserved genomic elements (UCEs), that universally enable target enrichment and sequencing of thousands of orthologous loci across species separated by hundreds of millions of years of evolution. Our analyses here focus on use of UCE markers in Amniota because UCEs and phylogenetic relationships are …

Strain Rate And Orientation Dependencies Of The Strength Of Single Crystalline Copper Under Compression, Virginie Dupont, Timothy C. Germann
Strain Rate And Orientation Dependencies Of The Strength Of Single Crystalline Copper Under Compression, Virginie Dupont, Timothy C. Germann
Aerospace Engineering - Daytona Beach
Molecular dynamics (MD) simulations are used to model the compression under uniaxial strain of copper single crystals of different orientations at various temperatures and strain rates. Uniaxial strain is used because of the close resemblance of the resulting stress state with the one behind a shock front, while allowing a control of parameters such as strain rate and temperature to better understand the behavior under complex dynamic shock conditions. Our simulations show that for most orientations, the yield strength of the sample is increased with increasing strain rate. This yield strength is also dependent on the orientation of the sample, …

The objective of this study was to determine the residual pro-or anti-oxidant effects in rat brain 30 days after systemic administration of a 5 nm citrate-stabilized ceria dispersion. A ∼4% aqueous ceria dispersion was iv-infused (0 or 85 mg/kg) into rats which were terminated 30 days later. Ceria concentration, localization, and chemical speciation in the brain was assessed by inductively coupled plasma mass spectrometry (ICP-MS), light and electron microscopy (EM), and electron energy loss spectroscopy (EELS), respectively. Pro- or anti-oxidant effects were evaluated by measuring levels of protein carbonyls (PC), 3-nitrotyrosine (3NT), and protein-bound-4-hydroxy-2-trans-nonenal (HNE) in the hippocampus, cortex, and …

Search For Zγ Events With Large Missing Transverse Energy In Pp- Collisions At √S=1.96tev, David Hedin, D0 Collaboration
Search For Zγ Events With Large Missing Transverse Energy In Pp- Collisions At √S=1.96tev, David Hedin, D0 Collaboration
Faculty Articles, Papers, and Other Scholarship
We present the first search for new phenomena in Zγ final states with large missing transverse energy using data corresponding to an integrated luminosity of 6.2 fb-1 collected with the D0 experiment in pp- collisions at √s=1.96TeV. This signature is predicted in gauge-mediated supersymmetry-breaking models, where the lightest neutralino χ-01 is the next-to-lightest supersymmetric particle and is produced in pairs, possibly through decay from heavier supersymmetric particles. The χ- 01 can decay either to a Z boson or a photon and an associated gravitino that escapes detection. We exclude this model at the 95% C.L. for supersymmetry-breaking scales of Λ < 87 TeV.

The Pierre Auger Observatory is exploring the potential of the radio detection technique to study extensive air showers induced by ultra-high energy cosmic rays. The Auger Engineering Radio Array (AERA) addresses both technological and scientific aspects of the radio technique. A first phase of AERA has been operating since September 2010 with detector stations observing radio signals at frequencies between 30 and 80 MHz. In this paper we present comparative studies to identify and optimize the antenna design for the final configuration of AERA consisting of 160 individual radio detector stations. The transient nature of the air shower signal requires …

Increasing college degree attainment for students from disadvantaged backgrounds is a prominent component of numerous state and federal legislation focused on higher education. In 1999, the National Science Foundation (NSF) instituted the "Computer Science, Engineering, and Mathematics Scholarships" (CSEMS) program; this initiative was designed to provide greater access and support to academically talented students from economically disadvantaged backgrounds. Originally intended to provide financial support to lower income students, this NSF program also advocated that additional professional development and advising would be strategies to increase undergraduate persistence to graduation. This innovative program for economically disadvantaged students was extended in 2004 to …
Purity And Decomposition Theorems For Staggered Sheaves, Pramod N. Achar, David Treumann
Purity And Decomposition Theorems For Staggered Sheaves, Pramod N. Achar, David Treumann
Faculty Publications
Two major results in the theory of ℓ-adic mixed constructible sheaves are the purity theorem (every simple perverse sheaf is pure) and the decomposition theorem (every pure object in the derived category is a direct sum of shifts of simple perverse sheaves). In this paper, we prove analogues of these results for coherent sheaves. Specifically, we work with staggered sheaves, which form the heart of a certain t-structure on the derived category of equivariant coherent sheaves. We prove, under some reasonable hypotheses, that every simple staggered sheaf is pure, and that every pure complex of coherent sheaves is a direct …
