An automation system helps companies to optimize their business operations by effectively controlling their production processes. Automation systems include the following major products: DCS, MES, PLC, PLM, APC, industrial sensors, industrial robotics, and SCADA. These automation products are widely used by different process industries including Oil and Gas, Power, Pharmaceutical, Pulp and Paper, and Food and Beverages. In addition, these automation products help companies by providing real-time information which improves the efficiency of the entire plant, and increases the total cost of ownership.

A CDN is a system of servers placed at various geographical locations to enable sharing of files among users in order to reduce loading time and avoid bottlenecks in users' networks. It is a large distributed system of servers deployed in multiple data centers across the internet. The goal of a CDN is to serve content to end-users ensuring high availability of content and high performance of the server. CDN servers are often used to speed up the delivery and loading time of websites. For example, a website can be hosted in the US, but some of the files (typically large images) can be hosted elsewhere so the main server serving the content doesn’t get slowed down. Additionally, these files may be hosted in a different country or even a different continent so the visitors from those regions can experience faster loading time on the website.

National Aeronautics and Space Administration (NASA) has developed a space-qualified, reprogrammable, Ka-band Software Defined Radio (SDR) to be utilized as part of an on-orbit, reconfigurable testbed. The testbed will operate on the truss of the International Space Station beginning in late 2012. Three unique SDRs comprise the testbed, and each radio is compliant to the Space Telecommunications Radio System (STRS) Architecture Standard. The testbed provides NASA, industry, other Government agencies, and academic partners the opportunity to develop communications, navigation, and networking applications in the laboratory and space environment, while at the same time advancing SDR technology, reducing risk, and enabling future mission capability. Designed and built by Harris Corporation, the Ka-band SDR is NASA's first space-qualified Ka-band SDR transceiver. The Harris SDR will also mark the first NASA user of the Ka-band capabilities of the Tracking Data and Relay Satellite System (TDRSS) for on-orbit operations. This paper describes the testbed's Ka-band System, including the SDR, travelling wave tube amplifier (TWTA), and antenna system. The reconfigurable aspects of the system enabled by SDR technology are discussed and the Ka-band system performance is presented as measured during extensive pre-flight testing.

The research project investigated foundational models of contracts in a higher-order world of programming. The primary thrust of the work explored the meaning of contracts. We focused on three questions. First, we determined what it means for a first-class function or object to satisfy a contract. Second, we worked out when it is correct for a contract monitoring system to blame a component for violating a contract. We could show that existing contract systems may point to an innocent component and thus send a programmer on a wild goose chase. Third, we established criteria for the completeness of monitoring systems. Using a model, we were able to demonstrate the completeness of one semantics for contract monitors. We used our primary model to explore designs for the parallel execution of contracts but without reaching a truly satisfactory answer. The secondary research project explored affine type systems as 'protocol contracts' and the use of behavioral contracts to connect an affine code base to libraries from conventional languages. The result of this work is a design for a practical, ML-style programming language with an affine type system and with a contract-based mechanism for integrating existing libraries.

This report describes the development of a software tool, entitled WildFire Ignition Resistance Estimator Wizard (WildFIRE Wizard, Version 2.10). This software was developed within the Wildfire Ignition Resistant Home Design (WIRHD) program, sponsored by the U. S. Department of Homeland Security, Science and Technology Directorate, Infrastructure Protection & Disaster Management Division. WildFIRE Wizard is a tool that enables homeowners to take preventive actions that will reduce their homes vulnerability to wildfire ignition sources (i.e., embers, radiant heat, and direct flame impingement) well in advance of a wildfire event. This report describes the development of the software, its operation, its technical basis and calculations, and steps taken to verify its performance.
