Sea-Bow International Sea-Bow. The Sea-Bow International Sea-Bow is a Canadian powered parachute, designed by Gerald Racicot and produced by Sea-Bow International, formerly called Valmecot Inc, of Valcourt, Quebec.

The aircraft was introduced in 2000 and production ended when the company went out of business in 2015.

Design and development
The aircraft was designed to comply with the Canadian Basic Ultra-Light Aeroplane rules. It features a parachute-style high-wing, single-place accommodation, with a second seat optional, tricycle landing gear and a single  Rotax 503 engine in pusher configuration. The  Rotax 582 engine is a factory option. Before it went out of production the  Rotax 618 engine was also an option.

The Sea-Bow is built from a combination of bolted 6061-T6 aluminium and 4130 steel tubing. In flight steering is accomplished via dual control sticks that actuate the canopy brakes, creating roll and yaw. The aircraft is turned right by pulling the right stick and left by pulling the left stick. On the ground the aircraft has lever-controlled nosewheel steering. The throttle control is located on the right stick. A number of canopies are available, including the El-Condor I, II and III eleven and thirteen cell models.

The Sea-Bow's most obvious unique feature is the fitting of four highly angled, saucer-shaped polyurethane wheels outboard of, and in addition to, the main wheels. These "spyros" provide stability on the ground and in flight and the company claims "the shape and the precise location and positioning of these wheels enable the Sea-Bow to safely land and take-off on different types of terrain and conditions such as grass, sand, gravel, asphalt, snow or ice". The aircraft can even be safely water-landed as the spyros provide adequate flotation. They also provide enough ground stability that crosswinds will not blow the vehicle over, but instead allow it to turn into the wind.

Poole and District Electric Tramways. The Poole and District Electric Tramways operated an electric tramway service in Poole between 1901 and 1905.

History

The Poole and District Electric Traction Company was a subsidiary of British Electric Traction. A single line was built from Poole railway station through Upper Parkstone to County Gates. The fare for the journey was 3d.

The company operated a fleet of 17 tramcars from a depot at Ashley Road in Upper Parkstone.

Closure

The system was bought by Poole Corporation in 1905 and leased for thirty years to Bournemouth Corporation Tramways from June 1905, and this line was subsumed into their system.

Livestock Water Recycling. Livestock Water Recycling, Inc. (LWR) is a privately owned Canadian company based in Calgary, Alberta. The environmental company focuses on livestock manure management of dairy, poultry, hog and digester CAFO livestock operations.

The company has built and manufactured industrial waste water treatment systems throughout North America since 1991. It conducts all design, production and manufacturing at its office in Calgary, Alberta. Initially, the company focused on wastewater remediation of oil and gas sites. In 2017 it began more focus on the agricultural industry.

The LWR Manure Treatment System 
The LWR Manure Treatment System uses mechanical and chemical processes to separate nutrients from manure in dairy or hog CAFO operations. The system produces dry solids, a liquid nutrient concentrate and clean potable water. Manure is rich in phosphorus, nitrogen, potassium, and ammonia. These nutrients can be used as fertilizer to improve crop production.

LWR currently has systems operating in Indiana, New York, Michigan, and Wisconsin.

Awards 

In 2011, LWR was recognized as a Top 10 Innovative Product in the 2011 Dairy Herd Innovation Awards at the World Dairy Expo in Madison, Wisconsin. Each entry was judged on its originality within the marketplace, usefulness and value to dairy farmers.

In 2010, LWR was recognized as a Top 10 New Products at the World Ag Expo in Tulare, California. The Top-10 new products are a favorite ‘must-see’ among World Ag Expo visitors.

In 2010, LWR was a recipient of the Emerald Award. The Emerald Awards celebrate the outstanding achievements by Albertans committed to protecting, preserving, enhancing and sustaining the environment.

In 2009, LWR won the Dr. F.X. Aherne Prize for Innovative Pork Production at the Banff Pork Seminar in Banff, Alberta. The award honors Canadian pork industry members who have developed original solutions to pork production challenges.

CNA PM.1. The CNA PM.1 was a single-engine light sport and training aircraft designed and built in Italy at the start of World War II.  After tests of the prototype a small production run was laid down but destroyed by bombing.

Design and development

The PM.1 was designed by students at the Instituto di Construzioni Aeronautische del Regio Politecnico di Milano in a 1938 competition for a modern, two-seat light private training and sports aircraft.  The name came from Polytechnic Milano. The prototype was built by CNA, first flying on 25 October 1939.

The PM.1 was a cantilever high-wing monoplane.  Its wing was straight-tapered, with rounded tips and long span ailerons, built of wood with a plywood skin.  The tailplane had a similar plan, placed on top of the fuselage with the trailing edge of the elevators in line with the rudder hinge so the rudder, which extended to the base of the fuselage, could move unimpeded. The fin and rudder were rounded and pointed; the rudder carried a trim tab.

The fuselage, also wooden and plywood-covered, was flat-sided, with car-type doors giving access to the side-by-side seats in the cabin which was placed under the leading edge of the wing.  In front, a compactly cowled, 40 kW (60 hp) CNA D.4 flat four engine drove a 2-blade propeller.  The PM.1 had a conventional undercarriage with mainwheels on centrally mounted, faired V-form half axles and with vertical legs to the bottom longerons, assisted by a tailskid.

Operational history

The outbreak of war and the need to concentrate on front-line aircraft delayed production of the PM.1, but an order for 10 was placed in August 1942. The partially completed aircraft were destroyed in an Allied bombing raid on Rome in July 1943; though the prototype avoided this event, it was destroyed later in the war.  Its design influenced that of the post-war Macchi MB.308, though the latter has a tricycle undercarriage and a markedly revised tail.

Prospector (spacecraft). Prospector was a proposed lunar probe that was intended to be flown in support of the Apollo lunar missions.

History
Prospector arose as a result of President John F. Kennedy's desire to rehabilitate the tarnished image of US spaceflight.  In 1961, NASA proposed a series of robotic probes, including Prospector, to be managed by the Jet Propulsion Laboratory.

Prospector was based on a study that had been performed by the Marshall Space Flight Center in June 1960, to determine what lunar missions could be achieved using the Saturn I rocket.

NASA envisioned Prospector as "a large versatile 'space truck'" that could be launched by a Saturn rocket and that could soft-land on the Moon with a wide variety of payloads.  Among the applications envisioned were:
 A remote-controlled lunar rover that could explore large areas of the lunar surface, including the far side of the Moon
 A system to obtain lunar samples and return them to Earth
 A low-altitude survey of the lunar surface for reconnaissance, and to help select landing sites for subsequent Apollo missions, using large propellant tanks to allow the spacecraft to hover and laterally move over the lunar surface
 An uncrewed cargo spacecraft, providing supplies and materials to lunar astronauts

Prospector was initially planned to have its first launch between 1963 and 1966.  However, as plans progressed, the project ran into weight overruns, requiring a larger launcher such as the Saturn V.   Its role also began to change from one of support for the Apollo missions to more of a substitute for them,  which NASA's Space Task Group did not endorse.  The project was canceled in 1962.

Load–store architecture. In computer engineering, a load–store architecture (or a register–register architecture) is an instruction set architecture that divides instructions into two categories: memory access (load and store between memory and registers) and ALU operations (which only occur between registers).

Some RISC architectures such as PowerPC, SPARC, RISC-V, ARM, and MIPS are load–store architectures.

For instance, in a load–store approach both operands and destination for an ADD operation must be in registers. This differs from a register–memory architecture (for example, a CISC instruction set architecture such as x86) in which one of the operands for the ADD operation may be in memory, while the other is in a register.

The earliest example of a load–store architecture was the CDC 6600. Almost all vector processors (including many GPUs) use the load–store approach.

Computer architecture
Register–memory architecture. In computer engineering, a register–memory architecture is an instruction set architecture that allows operations to be performed on (or from) memory, as well as registers. If the architecture allows all operands to be in memory or in registers, or in combinations, it is called a "register plus memory" architecture.

In a register–memory approach one of the operands for operations such as the ADD operation may be in memory, while the other is in a register. This differs from a load–store architecture (used by RISC designs such as MIPS) in which both operands for an ADD operation must be in registers before the ADD.

An example of register-memory architecture is Intel x86. Examples of register plus memory architecture are:

 IBM System/360 and its successors, which support memory-to-memory fixed-point decimal arithmetic operations, but not binary integer or floating-point arithmetic operations;
 PDP-11, which supports memory or register source and destination operands for most two-operand integer operations;
 VAX, which supports memory or register source and destination operands for binary integer and floating-point arithmetic;
 Motorola 68000 series, which supports integer arithmetic with a memory source or destination, but not with a memory source and destination. However, the 68000 can move data memory-to-memory with nearly all addressing modes.

Benson's algorithm. Benson's algorithm, named after Harold Benson, is a method for solving multi-objective linear programming problems and vector linear programs.  This works by finding the "efficient extreme points in the outcome set".  The primary concept in Benson's algorithm is to evaluate the upper image of the vector optimization problem by cutting planes.

Idea of algorithm 
Consider a vector linear program

for , ,  and a polyhedral convex ordering cone  having nonempty interior and containing no lines. The feasible set is . In particular, Benson's algorithm finds the extreme points of the set , which is called upper image.

In case of , one obtains the special case of a multi-objective linear program (multiobjective optimization).

Dual algorithm 
There is a dual variant of Benson's algorithm, which is based on geometric duality for multi-objective linear programs.
