ArpON. ArpON (ARP handler inspection) is a computer software project to improve network security. It has attracted interest among network managers and academic researchers and is frequently cited as a means of protecting against ARP-based attacks.

Motivation
The Address Resolution Protocol (ARP) has many security issues. These include the Man In The Middle (MITM) attack through the ARP spoofing, ARP cache poisoning, Denial of Service and ARP poison routing attacks.

Solution
ArpON is a host-based solution that makes the ARP secure and avoids the man-in-the-middle attack through ARP spoofing, ARP cache poisoning or ARP poison routing. This is possible using three kinds of anti-ARP-spoofing techniques:

 SARPI (Static ARP Inspection) for the statically configured networks without DHCP;
 DARPI (Dynamic ARP Inspection) for the dynamically configured networks with DHCP;
 HARPI (Hybrid ARP Inspection) for the statically and dynamically configured networks with DHCP.

The goal of ArpON is therefore to provide a secure and efficient network daemon that provides the SARPI, DARPI and HARPI anti-ARP-spoofing technique, thus making the ARP standardized protocol secure from any foreign intrusion.

Evektor EV-55 Outback. The Evektor EV-55 Outback is a twin-engine turboprop aircraft designed and built in the Czech Republic by Evektor-Aerotechnik. The prototype first flew on 24 June 2011.  The project's development was suspended in March 2017.

Development
In 2004 the company announced its plan to design and construct a two-engined utility aircraft that would carry up to 14 passengers or 4000 lb (1800 kg) of cargo, and operate from unimproved fields and at high-altitude airports.

The first prototype, an EV-55M (military version), flew from Kunovice Airport in June 2011, with company pilot Josef Charvat and military pilot Maj. Jiri Hana at the controls.
It was estimated at $2.1 to $2.2 million in 2012.
The first production-conforming aircraft flew from Kunovice in April 2016.

In June 2018, its price was $4 million and two aircraft should finish development flights with 200 hours in 2016, for 500 total hours.
Evektor secured enough investment to complete the certification process scheduled for 2017, with a minority investment from a Malaysian company backed by the country's former premier Mahathir Mohamad, but not to begin full production.

The project's development was suspended on 16 March 2017 due to "some uncertainties" with Evektor's Malaysian investor.

By December 2018, it was touted as a basis for an EVE-55 hybrid electric aircraft conversion to fly in 2020, with only one PT6A-21 running a  generator in the rear compartment, for much lower noise, an 18% fuel saving and the same payload and performance: a 3 hours endurance and 40 minutes from electric power only.

Design
The EV-55 is of conventional high-wing utility design with a T-tail. The prototype aircraft is powered by Pratt & Whitney PT6A-21 turboprop engines (535 shaft horsepower), driving four-blade propellers. The wing is mounted atop a nearly-square fuselage, which has five windows per side. The trailing-link tricycle landing gear retracts into the nose section or pods on the lower fuselage. Expected maximum cruise speed is 220 knots (407 km/h).

With nine passengers, range is 800nm (1,480km), it can take-off in 410m and land in 520m and with more speed, range and short take-off and landing capability, it can replace ageing piston-twins like the Cessna 421 and Britten-Norman Islander, or the smaller Cessna Caravan single turboprop when the payload-range of a larger turboprop such as the L-410 or Viking Twin Otter is not needed.
The less expensive, unpressurised EV-55 won't compete with the Pilatus PC-12 or Beechcraft King Air. 

The 5.02m x 1.61m cabin standard layout is five and four seats with a cargo compartment separated by a semi bulkhead and a L-410 sized double door at the rear.
It is equipped with a full glass cockpit, Czech firm Avia makes the four-blade propellers and Aero Vodochody the landing gear.

Landon-Era Birdbath. Birdbath, constructed of fieldstone and concrete, is an early 20th-century decorative feature on the historic Oldfields estate on the campus of the Indianapolis Museum of Art (IMA), in Indianapolis, Indiana. It is now an accessioned work of art in the collection of the IMA.

Description
This birdbath is constructed from large, smooth stones laid in concentric, circular tiers, set in a thick concrete mortar. The large basin of the bath curves out from a more cylindrical pedestal that slopes out a bit toward the ground. The overall silhouette resembles a chalice. The basin is lined with a coating of concrete and has been re-lined at least once. The most recent layer is made from concrete with a larger aggregate than the finer concrete used throughout the birdbath. There is no drainage or circulation system built into the bath.

Historical information
The grounds of Oldfields were landscaped by Percival Gallagher of the Olmsted Brothers in the 1920s; the birdbath presumably predates the Olmsted landscape. The property and all sculptures on it were donated to the IMA by the family of former Oldfields owner Josiah K. Lilly Jr., in 1967. In 2001 the outdoor sculptures were assessed, and eighteen selected pieces were accessioned into the IMA's Lilly House collection. Birdbath was assigned Accession Number LH2001.233.

Provenance
An undated Landon-era photograph (archived at the IMA) indicates that this birdbath has been on the Oldfields estate since the Landon era and possibly since before Gallagher's landscaping.

Nothing is known of its maker or origins. However, the materials are very similar to the original fountain base in the Formal Garden, which was constructed of similar field stone and concrete. (This can also be seen in historic photographs.) These may have been made from local materials, and perhaps they were built by the same person.

Location history
This birdbath has been on the Oldfields estate since the Landon era, when it was positioned in the middle of the scenic path along the property-bordering canal (as shown in an undated Landon-era photograph).

By 1990 the birdbath was moved for protection from traffic, as the canal path has become a utility road for IMA groundskeeping. The birdbath is now located near the path to the grounds barn.

Condition
The sculpture is monitored, cleaned, and treated regularly by the IMA art conservation staff.

Headworks. Headworks is a civil engineering term for any structure at the head or diversion point of a waterway. It is smaller than a barrage and is used to divert water from a river into a canal or from a large canal into a smaller canal.

An example is the Horseshoe Falls at the start of the Llangollen Canal.

Historically the phrase "headworks" derives from the traditional approach of diverting water at the start of an irrigation network and the location of these processes at the "head of the works".

Cyclone AX2000. The Cyclone AX2000 is a British built three axis microlight, first flown in the 1990s. It seats two in side-by-side configuration.

Design and development
The AX2000 is a development of the earlier Cyclone AX3, a UK regulation compliant variant of the French Ultralair Premier AX3. This, in turn, was a three axis development of the US Chotia Weedhopper from the early 1980s.

The Cyclone AX2000 is an aluminium tube framed three axis microlight with flying surfaces covered with a polyester fabric with outer PVF lamination (URLAM). The whole aircraft is built around a long, high aluminium keel boom, which bears the engine, wings and empennage. The wing is a two spar structure, with surfaces formed by upper and lower battens rather than ribs. It carries conventional, full span, tapering ailerons but no flaps. The tailplane is mounted on the keel and has an anti-balance/trim tab on the starboard elevator.  There is a small fixed fin below the keel but none above; the rudder is balanced and extends below the elevators, moving in a cut-out.

The short, deep fuselage is built around a wire braced tube beam. Lift and landing loads are taken by V-shaped, cross braced pairs of lift struts from the bottom of the fuselage to each wing, assisted by a centre line strut to the boom at the wing leading edge. The cockpit enclosure is non-structural, with forward opening doors to a pair of side-by-side seats. These are equipped with separate rudder pedals but the occupants share a central control column. The AX2000 has a tricycle undercarriage mounted close to the fuselage.

The engine is mounted, uncowled, ahead and above the wing leading edge, with the propeller shaft on the boom line. One of three engines may be fitted: a  Rotax 582/48 or  503 2V, both upright twin cylinder two strokes, or the  HKS 700E (either V3 or Beta variants), flat twin four stroke. Both Rotax engines drive propellers with ground adjustable pitch: the 582 has a three blade, composite propeller and the 503 a two blade wooden one.

As well the new engines, the AX2000 differs chiefly from the AX3 in having a completely double surface wing of reduced area and modified structure, a change of alloy for the main keel beam, a revised and lightened fuselage with new undercarriage, an increased fuel capacity and the addition of an elevator anti-balance trim tab.

The AX2000 is certificated as a glider tug, for gliders of class 1 and 2. A V-shaped forward tow line extension joins the main line to a pair of tug pillars attached to the rear spar on the under surfaces of the AX2000's wing.

Operational history
In mid-2011 there were 29 AX2000s on the UK civil aircraft register.

Variants

Final Frontier Design. Final Frontier Design is a seed-stage startup company that builds and tests spacesuits.  The company's products both enable, and are enabled by, the more recent lower-cost access to space epitomized by NewSpace launch companies such as SpaceX, Virgin Galactic and XCOR Aerospace.
FFD was awarded a Phase I SBIR in 2011 and developed pressure garment glove technology under this contract.

In July 2011, Final Frontier Design won third place in the 2011 NewSpace Business Plan Competition in Silicon Valley, sponsored by the Space Frontier Foundation.

In December 2014, Final Frontier Design obtained an official Space Act Agreement with NASA.

Company
Final Frontier Design was founded in 2010  by "artist and designer" Ted Southern, a former Eyebeam resident, and his partner Nikolay Moiseev, "a Russian mechanical engineer," with the intent to "craft affordable yet highly capable spacesuits for a burgeoning commercial spaceflight industry."

Intra-vehicular activity suit

Final Frontier is developing a low-cost commercial inside-the-spacecraft spacesuit called an Intra-Vehicular Activity suit (IVA) which can be pressurized in the event of an emergency, and is projecting to sell the suit at a price of about a fifth of the NASA cost for its existing line of IVA suits that cost around $250,000 each.  With the suit weighing a bit under —versus 30 pounds with the NASA suit—could result in economically significant reduction in fuel costs for a flight with a number of astronauts.
Final Frontier Design is building its third-generation spacesuit, according to the NASA flight certification standards. Its improvements over the second-generation spacesuit include the ability to withstand greater operating pressure, a carbon fiber waist ring, a retractable helmet, and improved gloves and glove disconnects.
The pair took to Kickstarter in June 2012 to raise money for the design and construction of a prototype commercial space suit for intra-vehicular travel — meaning activities that take place inside a spacecraft. Final Frontier had raked in more than $27,000 in July 2012 from 386 backers, exceeding their $20,000 fundraising goal.  The goal of the Kickstarter project is to prep a third-generation suit to present to NASA for flight certification by 2013.

Longlife. Longlife (Longlife - Sustainable, energy efficient residential buildings in regard to European requirements and innovative technologies in the Baltic Sea Region) is a transnational project in the Baltic Region. It is funded through the EU programme Baltic Sea Region 2007-2013. Longlife contributes to the EU Strategy 2020 framework to reduce energy consumption.

Longlife project 
Longlife is developing standards for sustainable, energy efficient building in the Baltic Region and harmonizing the different construction technologies. This includes standards for sustainability, procedures for planning, building permits and tendering and funding in the Baltic Region. One of the goals is to make the Baltic Region more competitive.

In the Longlife project partners from Denmark, Lithuania, Poland, Russia and Germany are working together. Lead Partner is the TU Berlin, Institute of Architecture, Chair of Design and Structure, Prof. Dr.-Ing. Klaus Rückert. The developed standards and benchmarks are minimum requirements for sustainable buildings. Considerations are made concerning the ecological, economic and social aspects in the life cycle of a building. The design process is supported by the Longlife prototype, a catalogue of materials, components and key technologies for energy efficiency and renewable energy sources that meet the minimum requirements of Longlife, e.g. the final energy consumption of 40kWh / m² year.

Longlife will demonstrate with Pilot projects that an extra effort in the integrated planning in order to minimize energy consumption and operating costs of a building life cycle is worthwhile.

At the end of the planning process, the building will be certified with the Longlife Performance Pass. This performance pass includes measurable data from the building in the fields of energy, costs and qualities. The practical solutions and innovative technologies are also applicable to other building types. Together with seven other projects Longlife will develop in 2012 a compendium which shows the potential and synergy of an energy cluster.

As a continuation of the project's work, the Longlife Institute e.V. was founded in September 2011.

Radab Windex. The Radab Windex is a family of Swedish high-wing, single-seat aerobatic gliders and motor gliders that was designed by Sven Olof Ridder and produced initially by Radab and later by WindexAir AB as a kit for amateur construction.

Design and development
The initial design was the unpowered model 1100. This was followed by the present production 1200C motorglider. The project started off in 1980 as a hobby design between Sven-Olof Ridder and Harald Undén, who later founded Radab to produce the design. By 1983 they had developed the custom airfoil section and tested it in a wind tunnel.

The first unpowered 1100 model flew in 1985, but the following year, as they geared up for kit production the factory burnt down, including all the fibreglass molds that they had built. Only two 1200 C aircraft kits had been produced before the molds were destroyed. One of these was completed in time to be flown at the 1987 Paris Airshow.

By 1990 the molds had been replaced and the first new 1200 C was completed. The first amateur-built Windex was completed from a kit in 1996. By 1999 WindexAir AB had assumed production from Radab.

The 1200 C is built from a combination of carbon-fiber-reinforced polymer and fibreglass. The aircraft is fully aerobatic and stressed to +9/-6g. The  span wing has carbon fibre spars and is of a semi-tapered planform. The wing employs a custom Radab KTH-FFA 17% thickness airfoil and features both Schempp-Hirth-style upper surface air brakes and 22.5% chord flaps for glidepath control. The König SC-430  two-stroke three-cylinder engine is mounted in tractor configuration and has a variable-pitch, fully feathering propeller.

When it was in production the Windex 1200 C was supplied in three kits, fuselage, wings and engine and propeller.

Operational history
In 1991 the prototype was flown at the FAI World Glider Aerobatic Championships held at Zielona Góra, Poland, winning two bronze medals.

In August 2011 there were four Windex motor gliders and one glider registered in the United States with the Federal Aviation Administration. All are in the Experimental - Amateur-built category.

Variants
