Network search engine. Computer networks are connected together to form larger networks such as campus networks, corporate networks, or the Internet. Routers are network devices that may be used to connect these networks (e.g., a home network connected to the network of an Internet service provider). When a router interconnects many networks or handles much network traffic, it may become a bottleneck and cause network congestion (i.e., traffic loss).

A number of techniques have been developed to prevent such problems. One of them is the network search engine (NSE), also known as network search element. This special-purpose device helps a router perform one of its core and repeated functions very fast: address lookup. Besides routing, NSE-based address lookup is also used to keep track of network service usage for billing purposes, or to look up patterns of information in the data passing through the network for security reasons  .

Network search engines are often available as ASIC chips to be interfaced with the network processor of the router. Content-addressable memory and Trie are two techniques commonly used when implementing NSEs.

4,4'-Biphenol. 4,4′-Biphenol is an aromatic organic compound, and one of three symmetrical isomers of biphenol. It is a colourless crystalline solid with a high melting point. It is primarily used in the production of polymers, particularly liquid crystals where it imparts high thermal stability.

Synthesis
The industrial synthesis of 4,4′-biphenol was developed by Allan Hay in the 1960s. As the direct oxidative coupling of phenol gives a mixture of isomers, 4,4′-biphenol is instead prepared from 2,6-di-tert-butylphenol, where para-coupling is the only possibility. The reaction with oxygen produces phenol-radicals which undergo rapid dimerisation, forming a diphenoquinone. This is reduced to the tetra-butyl-biphenyl derivative by a reaction with additional 2,6-di-tert-butylphenol, in an oxygen-free environment. In the final step, high temperature dealkylation is performed to remove the butyl groups, producing the desired 4,4′-biphenol product. If groups less bulky that t-butyl are used then polyphenylene ethers such as poly(p-phenylene oxide) can be produced.

Safety
4,4'-Biphenol had actually been elucidated to have an estrogenic SAR.

Analysis effort method. The analysis effort method is a method for estimating the duration of software engineering projects. It is best suited to producing initial estimates for the length of a job based on a known time duration for preparing a specification. Inputs to the method are numeric factors which indicate Size (S), Familiarity (F) and Complexity (C). These, with a duration for preparing the software specification can be used in a look up table (which contains factors based on previous experience) to determine with length of each of the following phases of the work. These being Design, Coding and Unit testing and Testing. The method does not include any times for training or project management.

This method should be used as one of a number of estimation techniques to obtain a more accurate estimate.

Aerial rigging. Aerial rigging is a specialty within the field of rigging that deals specifically with human loads. Aerial rigging is the process of setting up equipment used to make humans fly, specifically aerial circus and aerial dance equipment.

Aerial rigging is commonly practiced to different degrees by specialty fabricators, professional riggers, professional aerial artists, as well as amateur aerial artists. Most aerial circus equipment is built by fabricators around the world that build equipment specifically for the circus industry.

Aerial artists, both professional and amateur, often become riggers out of necessity. They generally learn to rig what they need.

WLA (Weak Link Analysis) is the process of systematically analyzing aerial rigging for the weakest link or links in the system. WLA is the most common process used by aerial riggers to assess and improve rigging. However, it is not the only system used.

Wrist roller. The wrist roller is a device designed for strengthening the forearm muscles together in a rolling-pulling motion. It consists of a bar of varying lengths, with a cord or rope attached, which the user rolls and unrolls. This is resisted by the weight of a mass at the bottom of the cord. Rolled and unrolled, it has a concentric and eccentric proportion. Different forearm muscles, specifically the flexors and extensors can be targeted by rolling the bar in opposite directions; that is by having the rope either on your side or on the opposite one respectively. It can even be performed (with lighter weights) manipulated by the fingertips to develop dexterity.

The length of the rope determines the length of time one will take to vary between the concentric and eccentric portions (though it will always be the same length, if rolled and unrolled at the same pace). Strength is built by using a larger weight. The focus on gripping muscles versus wrist extensor muscles can be varied based upon the thickness of the bar. Speed and explosiveness is obtained by rolling at faster paces, easier with lighter weights.

In addition to the rolling, there is also a function of wrist and shoulder supination inherent in the exercise, as one hand will hold and twist the weight, keeping the other side level, while the other lets go as to let it rotate and shift the grip. This is more apparent with heavier weights. Normally held in front of the body, this focus can be somewhat altered by the height/angle the bar is held at. A posture in which the arms are held in front of the pelvis is preferred as this reduces the weight borne by the shoulders and reduces the tendency for the elbow muscles to take up some of the work. This does however effectively shorten the length of rope or cord, so one may wish to stand on a raised platform of some sort if a more prolonged

International 110. The International 110 is an American sailboat that was designed by C. Raymond Hunt as a one-design racer and first built in 1939.

While most boat designs have numerical designations that reflect their length overall, waterline length, displacement or some other dimensional parameter, the 110 class was named for the sail number that the prototype carried.

In 1946 the 110 was developed into the larger  International 210.

Production
In the past the design has been built at home by amateur builders, as well by a number of American manufacturers, including Cape Cod Shipbuilding, W. D. Schock Corp, George Lawley & Son and Graves Yacht Yard. The current builder is New Holland Marine Group in the United States and it remains available for order. A total of 750 examples of the design have been completed.

W. D. Schock Corp records indicate that they built 17 boats between 1966 and 1971.

Design
The International 110 is a racing keelboat, with the early boats built from plywood and the more recent ones built predominantly of fiberglass, with wood trim. It has a fractional sloop rig with wooden or aluminum spars. The canoe hull features a flat bottom that allows planing. The hull has a plumb stem, a plumb transom, an internally mounted spade-type rudder mounted well forward and controlled by a tiller and a swept, fixed fin keel with a weighted bulb. It displaces  and carries  of iron ballast.

The boat has a draft of  with the standard keel.

For sailing the design is equipped with a spinnaker of , launched from a tube, plus a roller furling jib. It has a single trapeze, which is unusual in a keelboat. It has built-in buoyancy, which makes it unsinkable.

The design has a Portsmouth Yardstick DP-N racing average handicap of 89.6. It is normally sailed by a crew of two sailors or sometimes three.

Operational history
The boat is supported by an active class club that organizes racing events, the International 110 Class Association.

In 1994 it was reported that the majority of the 110 racing fleets were in New England, on the US west coast and the US upper midwest.

In a 1994 review Richard Sherwood wrote, "this fin-keeler was a breakthrough design of the late thirties. Rule changes, allowing a trapeze, enabled the 110 to win the Keel Division of the One-of-a-Kind Regatta in 1969. She points extremely well, planes on the flat bottom, and goes well downwind, but unless weight is kept well aft the bow tends to bury. Because of the very simple lines, the 110 is easy to build ... The cockpit is small and, with the narrow beam, it is difficult to work off the foredeck."

Web operations. Web operations (WebOps) is a domain of expertise within IT systems management that involves the deployment, operation, maintenance, tuning, and repair of web-based applications and systems. WebOps is also increasingly acknowledged as crucial to the success of digital marketing teams, and shows up as part of the MarTech (marketing technology) ecosystem.

Historically, operations were seen as a late phase of the Waterfall model development process. After engineering had built a software product, and QA had verified it as correct, it would be handed to a support staff to operate the working software. Such a view assumed that software was mostly immutable in production and that usage would be mostly stable. Increasingly, "a web application involves many specialists, but it takes people in web ops to ensure that everything works together throughout an application's lifetime". The role is gaining respect as a distinct specialty among developers and managers, and is considered by many to be a subset of the larger DevOps movement.

With the rise of web technologies since mid-1995, specialists have emerged that understand the complexities of running a web application. Earlier examples of IT operations teams exist, such as the Network Operations Center (NOC) and the Database Administration (DBA) function.

WebOps vs DevOps
Web applications are unique in many ways, presenting challenges that other software types do not have to deal with:
 Their use by a distributed, often uncontrolled, user base.
 The many independent networks between end users and the data center from which content is served.
 The way in which web pages are delivered as atomic transactions, requiring additional technologies (such as HTTP cookies) to associate sequences of pages into a user interaction.
 The three-tiered model of web, application, and database components (such as LAMP environments consisting of Linux, Apache, MySQL and either Perl or PHP).
 The requirement that you must often import the application's database and uploaded files (including potentially sensitive user data) to properly develop or test the application (such as when building a content management system, or using a CMS framework such as Drupal, Wordpress, or web frameworks like Django).
 WebOps includes front-end developers as key stakeholders

In this sense, WebOps simply refers to DevOps for web applications.

Responsibilities
Web operations teams are tasked with a variety of responsibilities, including:
 The deployment of web applications
 The monitoring, error isolation, escalation, and repair of problems
 Performing performance management, availability reporting, and other administration
 Configuring load-balancing and working with content delivery networks to improve the reliability and reduce the latency of the system
 Measuring the impact of changes to content, applications, networks, and infrastructure

Typically, web operations personnel are familiar with the TCP/IP stack, the http protocol, HTML page markup, and Rich Internet applications (RIAs) such as AJAX and the like.

Trap bar. The trap bar (also referred to as the hex bar) is an implement used in weight training. It is an assemblage of bars bent into an angle, then welded into a shape which lies flat in a plane, consisting of:
 A barstock welded into a hexagonal or diamond shape, sized to allow a person to stand in the middle
 Two (almost always) coaxial stub bars, welded to opposing positions on the outside of the perimeter of the hollow portion to hold weight plates. The stubs are used for loading the trapbar with plates.
 A set of handles pointing forward and back are welded inside the hollow portion. The handles are used to hold the trapbar while an exercise is performed. Note that these handles are aligned at a 90-degree angle to the plate-loading bars.

The trap bar was invented, patented and trademarked by Al Gerard, a competitive powerlifter. It is often thought to have been named after the (upper fibres of the) trapezius muscles, the muscle it was designed to train, with shoulder shrugs. In addition to shrugs, the bar is also used for trapbar deadlift, trapbar jumps, overhead/military presses, upright rows or "high pulls," and stiff leg deadlifts. Its design has since changed from various original designs into a hexagonal shape, and can be correctly referred to as a "hex bar".

Variants are produced by several vendors.
