  • 078400S02 FIRESTOPPING – Mechanical Room Floor Penetrations
    078400S02 FIRESTOPPING – Mechanical Room Floor Penetrations The following standard applies to all added floor penetrations in any existing mechanical room, electrical room or penthouse mechanical area above slab level in all facilities maintained by the University of Kentucky. Affected penetrations include, but are not limited to, the following: conduit, pipes, and ductwork. For new facilities, housekeeping curbs should be constructed during the initial building construction which would eliminate the need for this standard. 1.0 All penetrations must be fire stopped per the applicable NFPA (National Fire Protection Association) and State of Kentucky Building Codes with the appropriate UL listed fire stop assembly being utilized. The UL listing documentation must be available for the installed assembly upon request by the inspecting authority or by the University representative. 2.0 In addition to the required fire stopping outlined in section 1.0 above, all penetrations are to be protected by materials meeting an UL Tested Class 1 W-rating to restrict the flow of water. 3.0 For pipes and conduits, a curb is to be installed around the opening with a self leveling, single- component, silicone-based firestop sealant used in the slab and the curb. The installation is to consist of a steel angle mechanically fastened to the floor to create a curb with the firestop sealant installed in the curb and slab sealing up to the penetrating item. The sealant is to be white in color. See drawing 1 below for better clarification. 4.0 For ductwork, a curb is to be installed around the opening with a self leveling, single-component, silicone-based firestop sealant used in the slab and the curb.

  • Automotive Foundational Software Solutions for the Modern Vehicle Overview
    www.qnx.com AUTOMOTIVE FOUNDATIONAL SOFTWARE SOLUTIONS FOR THE MODERN VEHICLE OVERVIEW Dear colleagues in the automotive industry, We are in the midst of a pivotal moment in the evolution of the car. Connected and autonomous cars will have a place in history alongside the birth of industrialized production of automobiles, hybrid and electric vehicles, and the globalization of the market. The industry has stretched the boundaries of technology to create ideas and innovations previously only imaginable in sci-fi movies. However, building such cars is not without its challenges. AUTOMOTIVE SOFTWARE IS COMPLEX A modern vehicle has over 100 million lines of code and autonomous vehicles will contain the most complex software ever deployed by automakers. In addition to the size of software, the software supply chain made up of multiple tiers of software suppliers is unlikely to have common established coding and security standards. This adds a layer of uncertainty in the development of a vehicle. With increased reliance on software to control critical driving functions, software needs to adhere to two primary tenets, Safety and Security. SAFETY Modern vehicles require safety certification to ISO 26262 for systems such as ADAS and digital instrument clusters. Some of these critical systems require software that is pre-certified up to ISO 26262 ASIL D, the highest safety integrity level. SECURITY BlackBerry believes that there can be no safety without security. Hackers accessing a car through a non-critical ECU system can tamper or take over a safety-critical system, such as the steering, brakes or engine systems. As the software in a car grows so does the attack surface, which makes it more vulnerable to cyberattacks.

Bechtely, Elise McEllhineyy, Minje Kim?, Heechul Yuny y University of Kansas, USA. fmbechtel, elisemmc, [email protected] ? Indiana University, USA.

DeepPicar is a small scale requires a high computing capacity as well as the means to replication of a real self-driving car called DAVE-2 by NVIDIA. guaranteeing the timings. On the other hand, the computing DAVE-2 uses a deep convolutional neural network (CNN), which takes images from a front-facing camera as input and produces hardware platform must also satisfy cost, size, weight, and car steering angles as output. DeepPicar uses the same net- power constraints, which require a highly efficient computing work architecture—9 layers, 27 million connections and 250K platform. These two conflicting requirements complicate the parameters—and can drive itself in real-time using a web camera platform selection process as observed in [25]. and a Raspberry Pi 3 quad-core platform. Using DeepPicar, we To understand what kind of computing hardware is needed analyze the Pi 3’s computing capabilities to support end-to-end deep learning based real-time control of autonomous vehicles. for AI workloads, we need a testbed and realistic workloads.
