Virtual Sensor Middleware: A Middleware For Managing Iot Data For The Fog-Cloud Platform, Fadi Almahamid
Virtual Sensor Middleware: A Middleware For Managing Iot Data For The Fog-Cloud Platform, Fadi Almahamid
Electronic Thesis and Dissertation Repository
Internet of Things is a massively growing field where billions of devices are connected to the Internet using different protocols and produce an enormous amount of data. The produced data is consumed and processed by different applications to make operations more efficient. Application development is challenging, especially when applications access sensor data since IoT devices use different communication protocols.
The existing IoT architectures address some of these challenges. This thesis proposes an IoT Middleware that provides applications with the abstraction required of IoT devices while distributing the processing of sensor data to provide a real-time or near real-time response and …
Using A Data Warehouse As Part Of A General Business Process Data Analysis System, Amit Maor
Using A Data Warehouse As Part Of A General Business Process Data Analysis System, Amit Maor
CMC Senior Theses
Data analytics queries often involve aggregating over massive amounts of data, in order to detect trends in the data, make predictions about future data, and make business decisions as a result. As such, it is important that a database management system (DBMS) handling data analytics queries perform well when those queries involve massive amounts of data. A data warehouse is a DBMS which is designed specifically to handle data analytics queries.
This thesis describes the data warehouse Amazon Redshift, and how it was used to design a data analysis system for Laserfiche. Laserfiche is a software company that provides each …
Building A Scalable Global Data Processing Pipeline For Large Astronomical Photometric Datasets, Paul Doyle
Building A Scalable Global Data Processing Pipeline For Large Astronomical Photometric Datasets, Paul Doyle
Other
Astronomical photometry is the science of measuring the flux of a celestial object. Since its introduction, the CCD has been the principle method of measuring flux to calculate the apparent magnitude of an object. Each CCD image taken must go through a process of cleaning and calibration prior to its use. As the number of research telescopes increases the overall computing resources required for image processing also increases. Existing processing techniques are primarily sequential in nature, requiring increasingly powerful servers, faster disks and faster networks to process data. Existing High Performance Computing solutions involving high capacity data centres are complex …
High Performance Computing Markov Models Using Hadoop Mapreduce, Matthew Shaffer
High Performance Computing Markov Models Using Hadoop Mapreduce, Matthew Shaffer
e-Research: A Journal of Undergraduate Work
In this paper, I will explain how I used the probability modeling tool, Markov Models, in combination with Hadoop MapReduce parallel programming platform in order to quickly and efficiently analyses documents and create a probability model of them. I will explain what Markov Models are, give a brief overview of what MapReduce is, explain why Markov models can be used for document analysis, explain my code of the modeling program, and examine the performance of various MapReduce platforms and techniques in analyzing documents.
Collaborative Policy-Based Autonomic Management In Iaas Clouds, Omid Mola
Collaborative Policy-Based Autonomic Management In Iaas Clouds, Omid Mola
Electronic Thesis and Dissertation Repository
With the increasing number of "machines" (either virtual or physical) in a computing environment, it is becoming harder to monitor and manage these resources. Relying on human administrators, even with tools, is expensive and the growing complexity makes management even harder. The alternative is to look for automated approaches that can monitor and manage computing resources in real time with no human intervention. One of the approaches to this problem is policy-based autonomic management. However, in large systems having one single autonomic manager to manage everything is almost impossible. Therefore, multiple autonomic managers will be needed and these will need …
A Break In The Clouds: Towards A Cloud Definition, Chris Rose
A Break In The Clouds: Towards A Cloud Definition, Chris Rose
Walden Faculty and Staff Publications
This paper discusses the concept of Cloud Computing to achieve a complete definition of what a Cloud is, using the main characteristics typically associated with this paradigm in the literature. More than 20 definitions have been studied allowing for the extraction of a consensus definition as well as a minimum definition containing the essential characteris- tics. This paper pays much attention to the Grid paradigm, as it is often confused with Cloud technologies. We also de- scribe the relationships and distinctions between the Grid and Cloud approaches.
