European seasonal energy efficiency ratio. In Europe, the seasonal efficiency of refrigeration equipment, chillers and air conditioners is often rated by the European seasonal energy efficiency ratio (ESEER) which is controlled (among others) by the Eurovent Certification Company. A similar standard in the United States is the integrated energy efficiency ratio (IEER).

The ESEER is calculated by combining full and part load operating Energy Efficiency Ratios (EER), for different seasonal air or water temperatures, and including for appropriate weighting factors. These values are shown in the following table.

The formula for ESEER can then be presented as follows: 

ESEER = (EER@100% load × 0.03) + (EER@75% load × 0.33) + (EER@50% load × 0.41) + (EER@25% load × 0.23)

Eurovent publishes EER and ESEER values in its Directory of Certified Products together with cooling capacity and power input for standard conditions at full load for a wide variety of commercially available equipment.

UK Building Regulations Part L SEER
In the United Kingdom, a Seasonal Energy Efficiency ratio (SEER) for refrigeration and air conditioning products, similar to the ESEER but with different load profile weighting factors, is used for part of the Building Regulations Part L calculations within the Simplified Building Energy Model (SBEM) software, and are used in the production of Energy Performance Certificates (EPC) for new buildings within the UK and the European Union; both as part of the European directive on the energy performance of buildings (EPBD).

The formula for SEER can be presented as follows: 

SEER = a (EER@25% load) + b (EER@50% load) + c (EER@75% load) + d (EER@100% load)

where a,b,c,& d are the load profile weighting factors relevant to the proposed application.

South Lancashire Tramways. South Lancashire Tramways was a system of electric tramways in south Lancashire authorised by the South Lancashire Tramways Act 1900 (63 & 64 Vict. c. ccxliii). The South Lancashire Tramways Company was authorised by the act to build over  of track to serve the towns between St Helens (now in Merseyside), Swinton, Westhoughton and Hulton Lane where the Bolton Corporation system ended. The system was the largest standard-gauge electric tramway outside London.

The company had difficulty raising capital and at the end of November 1900 its shares were acquired by the South Lancashire Electric Traction and Power Company. It also acquired the shares of the Lancashire Light Railways Company and the South Lancashire Electric Supply Company. Construction began in late 1901 and in October 1902 the first section from Lowton through Leigh and Atherton to Four Lane Ends at Over Hulton opened.

Atherton became the centre of the system and the tram sheds, power station and offices were built on the north side of Leigh Road at Howe Bridge (grid reference ).  

Unrestored tram body, No 65 built by Brush Electrical Engineering Company in 1906, is in the collection of the Museum of Transport, Greater Manchester.

Marske XM-1. The Marske XM-1 was an American mid-wing, single-seat, experimental tailless glider that was designed and built by Jim Marske in 1957.

Experimentation with the XM-1 lead to the final configuration of the later Marske Pioneer.

Design and development
The first of Marske's flying wings was the XM-1, a design inspired by the flying wing designs of Charles Fauvel and Al Backstrom. He built the XM-1 when he was 19 years old. The aircraft went through several versions, each a modification of the same basic airframe as Marske experimented with configurations. The aircraft started off with fins on the wing tips and was later converted to a single fin at the rear of the short fuselage in its "XM-1D" configuration.

The XM-1 was built with a welded steel tube fuselage covered in fiberglass. The  wing was fabricated from wood and covered with doped aircraft fabric. The wing employed a 14% Fauvel airfoil. The landing gear was a fixed monowheel.

Only one XM-1 was built. It was registered with the US Federal Aviation Administration in the Experimental - Amateur-built category.

Operational history
The XM-1 was described by Soaring Magazine as "easy to fly". The aircraft was stall and spin proof. Marske sold the aircraft and it went through a series of owners. The XM-1 was later removed from the FAA register and likely no longer exists.

Variants

USS Jackson (LCS-6). USS Jackson (LCS-6) is an  of the United States Navy, and the first ship to be named for Jackson, the capital of Mississippi.

Design
In 2002, the U.S. Navy initiated a program to develop the first of a fleet of littoral combat ships.  The Navy initially ordered two trimaran hulled ships from General Dynamics, which became known as the Independence-class littoral combat ships after the first ship of the class, USS Independence.  Even-numbered U.S. Navy littoral combat ships are built using the Independence-class trimaran design, while odd-numbered ships are based on a competing design, the conventional monohull .  The initial order of littoral combat ships involved a total of four ships, including two of the Independence-class design. On 29 December 2010, the Navy announced that it was awarding Austal USA a contract to build ten additional Independence-class littoral combat ships.

Jackson is the third Independence-class littoral combat ship to be built. Jackson was built by Austal USA in Mobile, Alabama.  Jackson is the second Independence-class ship to carry standard  long rigid-hulled inflatable boats and improvements in corrosion protection and propulsion over the original Independence (LCS-2) design.

History 

Construction of Jackson began on 1 August 2011 with the first cutting of aluminum at Austal USA's Modular Manufacturing facility in Mobile, Alabama. The name of the ship was announced on 5 October 2011. The ship was launched on 14 December 2013. Jackson was delivered to the Navy on 11 August 2015 and placed into service that day. The ship was commissioned in a 5 December 2015 ceremony at Gulfport, Mississippi. She has been assigned to Littoral Combat Ship Squadron One

Jackson underwent the first of three shock trials in waters off Florida on 16 June 2016, and the last being reported having been completed the week prior to 20 July 2016.  A charge of  was set off at around  with the ship wired with around 260 instruments to record the effects.

On 23 May 2022, Jackson participated in the 28th Annual CARAT exercise with the Royal Thai Navy as a part of the Combined Task Force (CTF) 72. Jackson is attached to DESRON 7 and the US 7th Fleet. The MQ-8C Fire Scout unmanned helicopter was recently deployed on the ship.

Jackson is scheduled to be decommissioned sometime in 2024.

MonoCross. MonoCross is a C# .NET Model-view-controller (MVC) framework where the Model and Controller are shared across platforms and the View is implemented for every specific platform and/or target architecture. It allows the development of both native and HTML5 web apps that share business logic and data code. The pattern enables cross-platform portability of business logic and data access code, (Model + Controller), while supporting full, native and/or platform-specific presentation (Views). This enables separation of the presentation layer, (View) from the application code (Model + Controller). This modification enables portability of application code across multiple platform targets.

It uses MonoTouch to produce native iOS applications for iPhone, iPad, and iPod Touch, Mono for Android to creating native Android applications, and ASP.NET to support HTML5 apps using AJAX, CSS, and JavaScript.

The framework is mentioned in books, and is being used by large Fortune 500 enterprises in production.

Ocean Odyssey (FIRST). Ocean Odyssey is the 2005-06 FIRST Lego League challenge theme. It centered on topics relating to the world's oceans and oceanography. The challenge was developed with the collaboration of the Woods Hole Oceanographic Institution and the Monterey Bay Aquarium Research Institute.

Project
Teams were tasked with choosing an ocean activity or resource and research its impact on ocean health and productivity. From this, they would create an innovative solution to problems they encounter with the ocean. At competition, teams presented their research and solution to judges.

Gameplay
The table performance portion of Ocean Odyssey is played on a 4 ft by 8 ft field rimmed by wood boards. At competition, two of these fields are placed together to form an 8 ft square. In each -minute match, a team competes on each field with their robot to earn up to 400 points manipulating the mission models.

One of the mission models, Release the Dolphin, straddles both fields in the center. This model earns points for the team that releases the dolphin first.

The touch penalty objects are shipping crate models. All 8 are worth up to 5 points each depending on their location on the field, but are removed from play every time the robot is touched outside of base.

Missions

All of the Ocean Odyssey missions center on the oceans:
 Deploy the Submarine - up to 40 points
 Conduct a Transect Mapping - up to 75 points
 Protect the Pump Station - 40 points
 Service the Pipeline - 40 points
 Sample One Species From Among Others - 35 points

H-Store. H-Store is an experimental database management system (DBMS). It was designed for online transaction processing applications. H-Store was developed by a team at Brown University, Carnegie Mellon University, the Massachusetts Institute of Technology, and Yale University in 2007 by researchers Michael Stonebraker, Sam Madden, Andy Pavlo and Daniel Abadi.

Architecture
H-Store was promoted as a new class of parallel database management systems, called NewSQL, that provide the high-throughput and high-availability of NoSQL systems, but without giving up the transactional consistency of a traditional DBMS known as ACID (atomicity, consistency, isolation and durability). Such systems operate across multiple machines, as opposed to a single, more powerful, more expensive machine.

H-Store is able to execute transaction processing with high throughput by forgoing many features of traditional relational database management systems.

H-Store was designed as a parallel system to run on a cluster of shared-nothing, main memory executor nodes (processor + memory + storage). The database is partitioned into disjoint subsets each assigned to a single-threaded execution engine assigned to one core on one node. Each engine has exclusive access to all of the data in its partition. Because it is single-threaded, only one transaction at a time can access the data stored on that partition. No physical locks or latches are included in the system, and once a transaction is started, it cannot stall waiting for another transaction to complete. Throughput is increased by increasing the number of nodes in the system and reducing partition sizes.

Licensing
H-Store was licensed under the BSD license and GPL licenses. By 2009, the VoltDB company developed a commercial version, and the H-Store research group shut down in 2016.
