Xtractaurs. Xtractaurs is a line of toys by Mattel. Introduced in 2009, the brand is a fusion of regular action figures with an online game. It involves taking a dinosaur (both well-known and lesser-known dinosaurs) and extracting "DNA" samples from the dinosaur and analyzing it on your computer, similar in a way to the book and film Jurassic Park. If you own multiple dinosaurs and have extracted samples from all of them, you can create a genetically engineered hybrid on the computer to battle the "Megavores", ancient reawakened dinosaurs that share qualities with your dinosaur. Each dinosaur you purchase has a special ability, and combining them makes a fierce fighting animal (your first dinosaur, Tyrannosaurus rex, has the Chomp ability). This encourages the fusion of certain samples even more.

As of 2012, the https://www.xtractaurs.com site has been taken down, and no usable site has been implemented for the toy series. As a result, there is no use for the toy sets other than display.

Reception 
Xtractaurs have been reviewed by WIRED magazine and The Washington Times. The toys have also been the subject of an academic study published in the Journal of Early Childhood Literacy.

Gameplay 
To play the game, you must first purchase the Starter Kit, containing a DNA extractor gun, a Tyrannosaurus rex, and the Xtractaurs installation CD. You first must insert the CD into your computer to install the Xtractaurs software. Once installed, you can open the software, create an account (You must have Broadband Internet connection to play online), and can plug in your DNA extractor gun with a cable on the handle of the gun, which ends in a male USB plug. You are now ready for extraction. Your T. rex has a female TRS port, much like the one in an iPod or iPhone, in its thigh (as all dinosaurs under the brand do on a part of their body), and is compatible with a male TRS plug on the barrel of the extractor gun. When you plug the two, a display will appear on your screen showing a DNA strand. This means that electronics in the dinosaur are sending signals through the gun, through the cable, and into your computer. When done, an online version of your dinosaur pops up onto your screen. From there, you can play online games with your dinosaur, and begin your Xtractaurs adventure.

Human Friendly Transmission. The Human Friendly Transmission is the marketing name of a proprietary continuously variable transmission (CVT) made by Honda for its motorcycles, including the Honda DN-01 and EVO6 concept motorcycle.

The electronically controlled automatic transmission system is unlike more familiar belt-driven CVT systems used on scooters, nor does it have a torque converter, typical of automotive applications. Instead it is a hydrostatic drive that employs a variable displacement axial piston pump with a variable-angle swashplate. Prior to the DN-01, this type of system had not been used in road-going consumer motor vehicles, though it is familiar in industrial applications and heavy equipment such as forklifts and the US Air Force's MJ-1 bomb lift truck, in use since the 1950s. Honda has also dabbled in this technology since the 1950s. It appeared on their 2001 FourTrax Rubicon 4-wheel, off-road ATV.

The electronic controls allow the motorcycle to be operated in three modes: Drive, Sport and Manual. In Drive and Sport, it functions much like a CVT scooter, with infinitely variable gearing upshifted and downshifted automatically for what the system determines to be optimal performance. Unlike a scooter, engine braking is always available when decelerating. The difference between Drive and Sport modes is that Drive is optimized for economy while Sport is more responsive. In Manual mode, the transmission operates in one of six discrete gears chosen by the rider by pushing a plus/minus button on the left handlebar. It feels much like a normal motorcycle, including hitting the rev limiter at the top of each gear, but the electronic control unit (ECU) prevents upshifting and downshifting too soon. In all modes, it automatically returns to the lowest gear when stopped. It is also possible to switch into neutral while stopped, unlike a scooter.

Time-based one-time password. Time-based one-time password (TOTP) is a computer algorithm that generates a one-time password (OTP) using the current time as a source of uniqueness. As an extension of the HMAC-based one-time password algorithm (HOTP), it has been adopted as Internet Engineering Task Force (IETF) standard .

TOTP is the cornerstone of Initiative for Open Authentication (OATH) and is used in a number of two-factor authentication (2FA) systems.

History 

Through the collaboration of several OATH members, a TOTP draft was developed in order to create an industry-backed standard. It complements the event-based one-time standard HOTP, and it offers end user organizations and enterprises more choice in selecting technologies that best fit their application requirements and security guidelines. In 2008, OATH submitted a draft version of the specification to the IETF. This version incorporates all the feedback and commentary that the authors received from the technical community based on the prior versions submitted to the IETF. In May 2011, TOTP officially became RFC 6238.

Algorithm 

To establish TOTP authentication, the authenticatee and authenticator must pre-establish both the HOTP parameters and the following TOTP parameters:
 T, the Unix time from which to start counting time steps (default is 0),
 T, an interval which will be used to calculate the value of the counter C (default is 30 seconds).

Both the authenticator and the authenticatee compute the TOTP value, then the authenticator checks whether the TOTP value supplied by the authenticatee matches the locally generated TOTP value. Some authenticators allow values that should have been generated before or after the current time in order to account for slight clock skews, network latency and user delays.

TOTP uses the HOTP algorithm, replacing the counter with a non-decreasing value based on the current time:

 TOTP value(K) = HOTP value(K, C),

calculating counter valuewhere
 C is the count of the number of durations T between T and T,
 T is the current time in seconds since a particular epoch,
 T is the epoch as specified in seconds since the Unix epoch (e.g. if using Unix time, then T is 0),
 T is the length of one-time duration (e.g. 30 seconds).

Security 

Unlike passwords, TOTP codes are only valid for a limited time. However, users must enter TOTP codes into an authentication page, which creates the potential for phishing attacks.  Due to the short window in which TOTP codes are valid, attackers must proxy the credentials in real time.

TOTP credentials are also based on a shared secret known to both the client and the server, creating multiple locations from which a secret can be stolen. An attacker with access to this shared secret could generate new, valid TOTP codes at will. This can be a particular problem if the attacker breaches a large authentication database.

BCT common controller. The BCT Common controller (CC) serves as a controller for many different BCT (brigade combat team) unmanned systems.

The BCT CC consolidates control of numerous systems into one integrated networked controller, reducing the logistics footprint on the battlefield and empowering the soldier with enhanced intelligence, surveillance and reconnaissance capability. Being networked, the CC will also simplify training. The BCT CC controls the Class I unmanned aerial system (UAS), the Multifunctional Utility/Logistics and Equipment vehicle (MULE), the XM1216 Small Unmanned Ground Vehicle (SUGV), and urban unattended ground sensors (U-UGS). 

The BCT CC will communicate via the network in Spiral 2/3/4, will perform selected training, logistics/maintenance, medical, and other soldier functions.

As of December 2012, the US Army did not have a networked central control device for various unmanned platforms and sensors within the BCT. Still in development, the BCT CC will provide that capability and will be sent to the BCTs as it technologically matures.

SoaML. SoaML (Service-Oriented Architecture Modeling Language ) is an open source specification project from the Object Management Group (OMG), describing a Unified Modeling Language (UML) profile and metamodel for the modeling and design of services within a service-oriented architecture.

Description
SoaML has been created to support the following modeling capabilities:
 Identifying services, dependencies between them and services requirements
 Specifying services (functional capabilities, consumer expectations, the protocols and message exchange patterns)
 Defining service consumers and providers
 The policies for using and providing services
 Services classification schemes
 Integration with OMG Business Motivation Model
 Foundation for further extensions both related to integration with other OMG metamodels like BPDM and BPMN 2.0, as well as SBVR, OSM, ODM and others.

The existing models and meta models (e.g. TOGAF) for describing system architectures turned out to be insufficient to describe SOA in a precise and standardized way. The UML itself seems to be too general for the purpose of describing SOA and needed clarification and standardization of even basic terms like provider, consumer, etc.

STANAG 5066. STANAG 5066 (Profile for High Frequency (HF) Radio Data Communication) is a NATO Standardization Agreement specification to enable applications to communicate efficiently over HF radio.

STANAG 5066 provides peer protocols that operate above an HF modem and below the application level. STANAG 5066 includes the mandatory SIS (Subnet Interface Sublayer, sometimes called Subnet Interface Service) protocol that enables an application to connect to an HF modem through a STANAG 5066 server over TCP/IP. This enables a clean separation between application and modem.

The standard also defines two more layers, CAS which is intended to establish connections to other HF nodes and control the status of these connections, and DTS, which controls all the data manipulation for transmission (slicing, directioning, timing...) and the reconstruction in reception.

There are two basic modes of transmission defined by this standard. ARQ and NON-ARQ.
 ARQ uses package confirmation (through ACK response packages), and sliding window technique, which size is 128 elements. The "sending-services" can also have delivery confirmation of every package they send. It is necessarily a point-to-point protocol. It can be compared to TCP.
 NON-ARQ is a transmission mode in which the receiver node does not confirm the well-reception of the received packages. Receivers try to compose corrupted parts from future receptions, if it is impossible, the STANAG 5066 defines that the package has to be dispatched, and mark it with the known errored parts. This transmission mode allows to use point-to-point, point-to-group and broadcast. It can be compared to UDP in the IP philosophy.

STANAG 5066 defines a SIS-to-SIS package size of 2048 bytes maximum, when using point-to-point transmitting mode (ARQ or NON-ARQ), and 4096 bytes when using broadcast (NON-ARQ only).

VRAS. The Variable Room Acoustics System is an acoustic enhancement system for controlling room acoustics electronically. Such systems are increasingly being used to provide variable acoustics for multipurpose venues.

VRAS uses multiple microphones distributed around the room, fed via a multichannel digital reverberator to multiple loudspeakers to provide controllable enhancement of the reverberation time of the room. It is an example of a non-in-line or regenerative sound system which uses the inherent feedback of sound from the loudspeakers to the microphones to enhance the reverberation time for all sound source positions within the room. VRAS uses a unitary reverberator which maintains a constant power gain with frequency so that its inclusion does not affect the stability of the system (at each frequency the reverberator is a unitary matrix).

In addition, VRAS uses a number of microphones close to the stage area to detect early energy from the performers, which is used to generate early reflections. Such systems are termed in-line or non-regenerative. In-line systems aim to minimise the effects of regeneration by detecting stage sound at a high level, and may then be used to generate early reflections or late reverberation.

VRAS is thus a hybrid system that uses both regenerative and non-regenerative approaches.

VRAS was developed by Mark Poletti at Industrial Research Limited, New Zealand and commercialized by LCS Audio. VRAS is now a part of the Meyer Sound Laboratories Constellation System.

Carriers at War. Carriers at War 1941-1945: Fleet Carrier Operations in the Pacific is a 1984 computer wargame by Strategic Studies Group for Apple II and Commodore 64. The game was designed by Roger Keating and Ian Trout. A remake, Carriers at War, was released for DOS in 1992. A sequel to the remake, Carriers at War II, was released for DOS and Mac OS in 1993. A second remake was published by Matrix Games in 2007 for Microsoft Windows.

Reception

II Computing in 1985 called the Apple II version of Carriers at War "the best-playing simulation of naval warfare I have seen on either tabletop or video monitor" and favorably citing its historical accuracy. inCider was less positive, rating the Apple II version two stars in 1986. The reviewer stated that the game "is so difficult to master, it takes much of the joy out of playing it ... Carriers' big drawback is its complexity", adding that he preferred Gary Grigsby's SSI naval games as "they're less flexible, but they're just as detailed and much more playable". Computer Gaming World stated that "Carriers at War is the best game available on World War II carrier operations. It is, perhaps, the best wargame of 1984 on any topic".

Carriers at War was awarded the Charles S. Roberts Award for "Best Adventure Game for Home Computer of 1984".

A 1987 overview of World War II simulations in the Computer Gaming World rated the game four of five points and stated that "it excels in flexibility, options and limited intelligence". A 1993 survey in the magazine of wargames gave it three stars out of five, stating "Highly recommended for the 8-bit market". In 1994 the magazine said that the 8-bit version was "one of the first computer wargames to approach the complexity of board wargame simulations while still remaining playable and fun".
