The river is picturesque and described as Wind in the Willows country. Kenneth Graham based much of his book on this part of the Thames.
Cookham was home to the artist Stanley Spencer’s whose works include Swan Upping at Cookham.
The Vermaport® Cart Conveying System is the trademarked name of conveyor systems built by Darrott (Germany) that are designed to transport shopping carts between floors of a retail establishment or to transport or store luggage carts at airports or other transportation hubs. Vermaport Cart Conveying Systems are alternatives to inclined moving walkways, a Vermaport will take up much less space than the walkway.
The Vermaport SC (Shopping Cart) is typically used in discount retailers such as Target and Kmart, as well as furniture store IKEA, and the retail chain Bed Bath and Beyond. Essentially an escalator, the device uses specially designed shopping carts and transports them between levels in shopping complexes.
Along the path of the Vermaport there are three valleys. The special carts have their front wheels set closer together and out of parallel to the back, outset, wheels. On the way up the inset wheels glide along the center valley, which is lower than the two outer valleys that the outset wheels ride along. This allows the shopping cart to stay level while moving along an inclined path. On the way down, the center valley is higher and the side valleys are lower to allow the cart to transport level while facing down the Vermaport. Due to these valleys, shopping carts on the Vermaport SC do not have the typical plastic or metal grate shelf below the basket of the shopping cart that is used to carry large or bulk items.
An installed Vermaport system is typically located next to an escalator, moving at the same speed, so as to allow a shopping cart to be transported alongside a shopper as he or she moves between floors. The conveyance is accomplished by a belt of hard rubber teeth that grab near the wheels of the cart as a shopper guides it into the entrance of the Vermaport.
The world’s largest Vermaport is located in Kmart in Middle Village, Queens, New York City, New York. It has a length of 120 ft (37 m) and a vertical rise of 50 ft (15 m).
The Vermaport LC (Luggage Cart) is based on the same engineering principles and the SC model. It allows travellers and their luggage to travel between floors in transportation terminals such as an airport. The LC system allows for items wider than what would fit into a shopping cart on the Vermaport SC.
The Vermaport RS (Return System) is used to store luggage carts which are typically rental fee based. Personnel at an arrival or departure area will gather abandoned luggage carts and return them to the Vermaport RS. The carts will be automatically feed into the Vermaport and will wait for a traveler to retrieve one by inserting the required fee.
Bingley Three Rise Locks is a staircase of three locks on the Leeds and Liverpool Canal at Bingley. It opened in 1774 and was a major feat of engineering at the time along with the larger Five Rise (more details on construction and history here) opened at the same time just a few hundred meters further up. The lock comprises a ’staircase’ flight - the lower gate of one lock forms the upper gate of the next lock.
In Databases and Transaction processing, Two phase locking, (2PL) is a concurrency control locking protocol, mechanism, that guarantees Serializability. It is also the name of a class (set) of transaction schedules. Using locks that block processes, 2PL is subject to deadlocks that result from the mutual blocking of two transactions or more.
According to the Two phase locking protocol, locks are handled by a transaction in two distinct, consecutive phases during the transaction’s execution:
Phase 1: Locks are acquired and no locks are released.
Phase 2: Locks are released and no locks are acquired.
The serializability property is guaranteed for a schedule with transactions that obey the protocol. The 2PL schedule class is defined as the class of all the schedules comprising transactions with data access orders that could be generated by the 2PL protocol.
The Strict two phase locking (S2PL) class of schedules is the intersection of the 2PL class with the class of schedules possessing the Strictness property.
To comply with the S2PL protocol a transaction needs to comply with 2PL, and release its write (exclusive) locks only after it has ended, i.e., being either committed or aborted.
S2PL is a special case of 2PL, i.e., the S2PL class is a proper subclass of 2PL.
Strong strict two phase locking
To comply with the Strong strict two phase locking (SS2PL) protocol a transaction needs to comply with 2PL, and release both its write (exclusive) and read (shared) locks only after it has ended, i.e., being either committed or aborted.
A transaction obeying SS2PL can be viewed as having Phase 1 that lasts its entire execution duration, and no Phase 2 (or degenerate Phase 2). Thus, only one phase is actually left, and “two-phase” in the name seems to be still utilized due to the historical development of the concept from 2PL. The SS2PL property of a schedule is also called Rigorousness, and an SS2PL schedule is also called a Rigorous schedule.
SS2PL is a special case of S2PL, i.e., the SS2PL class of schedules is a proper subclass of S2PL (every SS2PL schedule is also an S2PL schedule, but S2PL schedules exist that are not SS2PL).
SS2PL is the concurrency control protocol of choice for most database systems since it provides besides serializability also Strictness, which is instrumental for efficient database recovery, and also Commitment ordering (CO) for participating in environments where a CO based Global serializability solution is employed.
NSB BM92 is a Norwegian diesel railway multiple unit manufactured by Duewag. It is used for commuter trains around Trondheim (Trønderbanen), on Meråkerbanen (Nabotåget) and occasionally on Rørosbanen. The train is not equipped with as many amenities as the NSB BM93 which is used on longer services.
A BM92 trainset consists of two carriages. Four of the fourteen sets are equipped with a large luggage room. They were built between 1984 and 1985. On January 4 2000, a BM92 set with luggage room was lost in a fatal collision on Rørosbanen, the Åsta accident, which killed a total of 19 people.
The Southern Railway (SR) gave the designation CW to the fleet of AC electric multiple units used on the lines to Coulsdon and Wallington. They were planned by the London, Brighton and South Coast Railway but were delayed by the Grouping and were introduced by the Southern Railway.
The CW (Coulsdon and Wallington stock) units were built in 1923-1924, as the last electric train stock for use on the LBSCR AC overhead electrified lines in South London. This stock comprised some hundred carriages, which were used in five car formations (Driving Trailer Third + Driving Trailer Composite + Motor Luggage Van + Trailer Composite + Driving Trailer Third).
The stock, built by the Metropolitan Carriage Wagon & Finance Company at Birmingham, was as follows:
The Motor Luggage Vans (nicknamed “Milk Vans”) each had four 250 horsepower GEC traction motors.
After the replacement of the AC overhead equipment by the 660 V DC third rail system adopted as standard by the SR, the carriages that formed these units were rebuilt accordingly, the Motor Luggage Vans becoming goods train guard’s vans.
The Halden canal near Halden, Norway begun construction in 1852. The canal allows boats to make a journey parallel to the Swedish border of 75 km from Tistedal to Skulerud. Engebret Soot (1786 - 1859) was responsible for this canal, as well as the earlier Soot Canal.
Four sets of locks control the water in the canal. From 1857 - 1860 the Strømsfoss and Ørje locks were built. There are 3 locks at Ørje, with a combined lift height of 10 meters. The lock gates are controlled by hand. In 1865 the Stenselv river portion of the canal, with locks both at Krappeto, was completed. The Brekke locks, furthest south, were finished in 1924 with four locks and a combined lift height of 26.6 m, bypassing the greatest lift of the Telemark canal. The locks in the Halden Canal can pass vessels which are 24 m in length, 6 m in beam and of 1.6 m draft.
The Kyle Web, also known as the psiberweb, is an interstellar and instantaneous communication network in Catherine Asaro’s novels Saga of the Skolian Empire.
The network can be thought of as similar to the Internet. It has however an enormous size and data capacity, spanning numerous star systems and capable of carrying massive amounts of data. Numerous computer networks connect to the Kyle Web in order to share information.
Unlike internet, the psiberweb, rather than existing in real physical form, transmits information through Kyle space. Also known as the psiberspace, the Kyle space is an alternate dimension, that exists separately from our conventional concepts of time and space. It is based heavily on quantum theory and Fourier transforms. It can be also described as an “universe of thoughts”, as the only people who can connect to the psiberweb are psions. When a thought is transmitted in the Kyle Web, it exists (is received) simultaneously everywhere across the entire network.
The psiberweb was created and used in Skolian Empire and is crucial in their defence. Access and control of the psiberweb is what gives the Skolian Empire its equal strength to the more powerful and more numerous Trader empire.
To create and maintain a psiberweb in the Kyle space, a Rhon psion is needed, the only known Rhons being the members of Ruby Dynasty, the ruling family of Skolian Empire. Less powerful but still strong psions called telops can also access and use the Kyle Web, but cannot construct it or “enter” Kyle space.
The Triad is the three person group that powers the psiberweb, both as director of the physical medium and as administrator of the interstellar networks in Kyle space. Originally a Dyad, the members of the Ruby Dynasty eventually discovered that three people can comprise the group and maintain the Kyle Web.
Triad members, so called Keys, have substantial political influence. A person joins the Triad by touching the singularity found in the Locks, gaining so the capability to create the web connections and nodes of the psiberweb. A member of the Triad/Dyad must be a Rhon psion, as those are the only genetically suited humans capable of interfacing with the Locks.
A Lock is one of three powerful sentient machines created by the ancient Ruby Empire. It is a disruption in normal spacetime, which manifests as a great column of light called a “Kyle singularity”. The Locks’ construction apparently is the result of advanced mathematics, neuroscience and mysticism. The ancient technology which created the Locks has been lost, but people of the Skolian Empire have deduced some of its functioning.
There are three known remaining Locks since the fall of the original Ruby Empire:

The McAlpine Locks and Dam refers to the series of locks and the hydroelectric dam in Louisville, Kentucky at the Falls of the Ohio. They are located at mile point 606.8 and control a 72.9 mile (117 km) long navigation pool. This was the first major engineering project on the Ohio River, and the first official name of the system of canal locks was the Louisville and Portland Canal, which was completed in 1830 to allow shipping traffic to navigate through the Falls of the Ohio. From 1925 to 1927, a dam for generating hydroelectric power was added, and the system of canals was expanded, first by a private company and then by the U.S. Army Corps of Engineers. The hydroelectric plant at the time was the seventh largest hydroelectric plant in the United States.
The system was renamed the McAlpine Locks and Dam in 1960 in honor of William McAlpine, who was the only civilian to have ever served as district engineer for the Corps of Louisville. At present, the normal pool elevation is 420 feet (130 m) above sea level and the drainage area above the dam is 91,170 square miles (236,000 km²). The average daily flow at McAlpine is 118,000 cubic feet per second (3,340 m³/s). The lock chambers are located at the dam on the Kentucky side of the Ohio River and are capable of a normal lift of 37 feet (11 m) between the McAlpine pool upstream and the Cannelton pool downstream. The hydroelectric plant consists of eight turbine units with a net power generation capacity of 80,000 kilowatts. The hydroelectric plant is currently undergoing an 8-year long rehabilitation project. This will extend the life of the 1920s era turbine-generator units and increase power output to 100 megawatts.
In October 2003, McAlpine was designated a Historic Civil Engineering Landmark by the American Society of Civil Engineers.
The McAlpine locks are currently undergoing a 10-year, $278 million expansion project scheduled to be completed in 2008.
The hydroelectric plant is owned and operated by LG&E, a subsidiary of E.ON U.S., while the locks are operated by the Army Corps of Engineers.
Small joint manipulation refers to twisting, pulling or bending fingers or toes to cause joint locks in the various joints in those appendages. Joint locks on fingers and toes are respectively referred to as finger locks and toe locks.
The leverage needed for such joint manipulation is comparatively small, since grabbing a finger or two with one or both hands creates a distinct advantage, and means that a weaker person can possibly control a stronger one. Grabbing only one finger may lead to the opponent being able to pull it free, while grabbing three or more reduces the leverage advantage considerably, and hence it is sometimes advised to grab two fingers for maximum effect.
Small joint manipulation is an illegal technique in most combat sports that feature joint locking such as Brazilian Jiu-Jitsu, Judo, Mixed Martial Arts and Sambo, since unlike standard joint locks, there is less of an opportunity to tap out before the small joint breaks. It is however sometimes taught as a self-defense and pain compliance technique, for instance in Kenpo, Jujutsu, and especially in ‘Small Circle JuJitsu’. It is also an important part of koppo-techniques, e.g. in ninjutsu.
