Surface Defect Detection of Strip-Steel
Surface-defect detection is crucial for assuring the quality of strip-steel manufacturing. Strip-steel surface-defect detection requires defect classification and precision localization, which is a challenge in real-world applications.

Foreshadow (Security Vulnerability)
Foreshadow (known as L1 Terminal Fault (L1TF) by Intel) is a vulnerability that affects modern microprocessors that was first discovered by two independent teams of researchers in January 2018, but was first disclosed to the public on 14 August 2018. The vulnerability is a speculative execution attack on Intel processors that may result in the disclosure of sensitive information stored in personal computers and third-party clouds. There are two versions: the first version (original/Foreshadow) (CVE-2018-3615) targets data from SGX enclaves; and the second version (next-generation/Foreshadow-NG) (CVE-2018-3620 and CVE-2018-3646) targets virtual machines (VMs), hypervisors (VMM), operating systems (OS) kernel memory, and System Management Mode (SMM) memory. A listing of affected Intel hardware has been posted. Foreshadow is similar to the Spectre security vulnerabilities discovered earlier to affect Intel and AMD chips, and the Meltdown vulnerability that also affected Intel. However, AMD products, according to AMD, are not affected by the Foreshadow security flaws. According to one expert, " lets malicious software break into secure areas that even the Spectre and Meltdown flaws couldn't crack". Nonetheless, one of the variants of Foreshadow goes beyond Intel chips with SGX technology, and affects "all [Intel] Core processors built over the last seven years". Foreshadow may be very difficult to exploit, and there seems to be no evidence to date (15 August 2018) of any serious hacking involving the Foreshadow vulnerabilities. Nevertheless, applying software patches may help alleviate some concern, although the balance between security and performance may be a worthy consideration. Companies performing cloud computing may see a significant decrease in their overall computing power; individuals, however, may not likely see any performance impact, according to researchers. The real fix, according to Intel, is by replacing today's processors. Intel further states, "These changes begin with our next-generation Intel Xeon Scalable processors (code-named Cascade Lake), as well as new client processors expected to launch later this year ." On 16 August 2018, researchers presented technical details of the Foreshadow security vulnerabilities in a seminar, and publication, entitled "Foreshadow: Extracting the Keys to the Intel SGX Kingdom with Transient Out-of-Order Execution" at a USENIX security conference.

Interference in B5G Network Design
Beyond Fifth Generation (B5G) networks are expected to be the most efficient cellular wireless networks with greater capacity, lower latency, and higher speed than the current networks. Key enabling technologies, such as millimeter-wave (mm-wave), beamforming, Massive Multiple-Input Multiple-Output (M-MIMO), Device-to-Device (D2D), Relay Node (RN), and Heterogeneous Networks (HetNets) are essential to enable the new network to keep growing. In the forthcoming wireless networks with massive random deployment, frequency re-use strategies and multiple low power nodes, severe interference issues will impact the system. Consequently, interference management represents the main challenge for future wireless networks, commonly referred to as B5G.

USB Dead Drop
A USB dead drop is a USB mass storage device installed in a public space. For example, a USB flash drive might be mounted in an outdoor brick wall and fixed in place with fast concrete. Members of the public are implicitly invited to find files, or leave files, on a dead drop by directly plugging their laptop into the wall-mounted USB stick in order to transfer data. (It is also possible to use smartphones and tablets for this purpose, by utilizing a USB on-the-go cable.) The dead drops can therefore be regarded as an anonymous, offline, peer-to-peer file sharing network. However, in practice USB dead drops are often used for social or artistic reasons, rather than for practical ones.

Yarovaya Law
The Yarovaya law (in Russian: Закон Яровой, transliteration: Zakon Jarovoy), also Yarovaya package/bag, is a set of two Russia n federal bills, 374-FZ and 375-FZ, passed in 2016. The bills amend previous counter-terrorism law and separate laws regulating additional counter-terror and public safety measures. It is known to the public under the last name of one of its creators—Irina Yarovaya. The amendments included an expansion of authority for law enforcement agencies, new requirements for data collection and mandatory decoding in the telecommunications industry, as well as the increased regulation of evangelism, including a ban on the performance of "missionary activities" in non-religious settings.

Roadrunner (Supercomputer)
Roadrunner was a supercomputer built by IBM for the Los Alamos National Laboratory in New Mexico, USA. The US$100-million Roadrunner was designed for a peak performance of 1.7 petaflops. It achieved 1.026 petaflops on May 25, 2008, to become the world's first TOP500 LINPACK sustained 1.0 petaflops system. In November 2008, it reached a top performance of 1.456 petaFLOPS, retaining its top spot in the TOP500 list. It was also the fourth-most energy-efficient supercomputer in the world on the Supermicro Green500 list, with an operational rate of 444.94 megaflops per watt of power used. The hybrid Roadrunner design was then reused for several other energy efficient supercomputers. Roadrunner was decommissioned by Los Alamos on March 31, 2013. In its place, Los Alamos commissioned a supercomputer called Cielo, which was installed in 2010. Cielo was smaller and more energy efficient than Roadrunner, and cost $54 million.

Pedestrian Identification and Classification in Autonomous Vehicles
Pedestrian detection is at the core of autonomous road vehicle navigation systems as they allow a vehicle to understand where potential hazards lie in the surrounding area and enable it to act in such a way that avoids traffic-accidents, which may result in individuals being harmed. This paper demonstrates that the use of image augmentation on training data can yield varying results.
