John Wimpenny. John Wimpenny (3 December 1922 – 27 April 2015) was an English aeronautical engineer who held the record for the longest human powered flight.

Career
Wimpenny was born in London, growing up in Palmers Green and Winchmore Hill. He attended Minchenden Grammar School in Southgate and in 1958 he moved to St Albans, Hertfordshire, where he lived for the rest of his life.

John Wimpenny's career as an aeronautical engineer began at the de Havilland Aircraft Company in Hatfield, Hertfordshire, in October 1940, and he went on to work on the Mosquito, Tiger Moth, Hornet, Vampire and Comet aircraft projects, becoming Deputy Chief Aerodynamicist in 1957. He later worked for Hawker Siddeley Aviation in the capacity of Chief Research Engineer from 1965. He worked on the development of the Hawker Siddeley HS 125 executive jet and on civil STOL and V/STOL design in co-operation with the Dornier Aircraft Company in Germany. He was promoted to the position of Director of Research at Hawker Siddeley in Hatfield and later became Executive Director of Research at British Aerospace in Kingston upon Thames.

Human-powered aircraft

The Hatfield Puffin, a human-powered aircraft intended for an attempt at the Kremer prize, was designed by a team headed by John Wimpenny, by then an aerodynamicist, and built by volunteers at the de Havilland Aircraft Company in Hatfield, Hertfordshire, UK.

Record-breaking flight in the Puffin

On 2 May 1962, Wimpenny, aged 39, piloted the Puffin, pedalling like a cyclist to make the propeller drive the aircraft, and he achieved a flight distance of 993 yards, then a world record which was to stand for ten years.

Later life

John Wimpenny was visiting professor for undergraduate research projects at City University London from 1990 to 1999 and he was Vice-Chairman of the Royal Aeronautical Society's Human Powered Aircraft Group from 1995 until his death.

Honours and awards

1976 Hodgson Prize for his paper on 'Costs and Decision-Making'

1978 Royal Aeronautical Society Silver Medal for his many important contributions in practical aeronautics

1983 Hodgson Prize for his paper 'Aircraft R and D in Europe - A Perspective View'

Shade ball. A shade ball is a small plastic sphere floated on top of a reservoir for environmental reasons, including to slow evaporation and prevent sunlight from causing reactions among chemical compounds present in the water. Also known as bird balls, they were developed initially to prevent birds from landing on bodies of water.

History
Shade balls were originally known as bird balls, as they were developed initially to prevent birds from landing on toxic tailing ponds produced by mining operations.

They have also been used by airports to prevent birds from being attracted to nearby drainage ponds thus reducing collisions with planes.

Usage by LADWP

Starting in mid-2009, the Los Angeles Department of Water and Power (LADWP) put about 400,000 balls in the Ivanhoe reservoir with the main objective of preventing the formation of a carcinogenic chemical, bromate, which forms when sunlight interacts with naturally occurring bromine and the chlorine added to prevent algae growth. In the original release by the LADWP, there is no mention of water conservation as an objective and the project was planned for a five-year life span, until a Griffith Park project was completed. The reduction in evaporation led to an estimated savings of about  of water in one year.

In 2014 and 2015, the LADWP put 96 million shade balls onto its largest reservoir (Las Virgenes) in response to the United States Environmental Protection Agency's surface water treatment rule, which requires large reservoirs of treated water to be covered. The LADWP says that in addition to reducing evaporation, they also reduce UV radiation by-products and algae growth. The balls saved 1.7 million cubic metres of water from evaporating during their deployment from August 2015 to March 2017. However, they required 2.9 million cubic metres of water in their manufacture. Nevertheless, the balls have a lifespan of ten years, and the plastic may be reused after that.

Construction

The shade balls used in the Los Angeles project are made of high-density polyethylene (HDPE) with carbon black additive to protect the plastic from ultraviolet radiation. Adding carbon black also prevents the formation of bromate, a suspected human carcinogen.

They are about  in diameter, and are partially filled with water to avoid being blown by wind. HDPE plastic is commonly used for food and beverage containers as well as water distribution pipes.

Swedish Volunteer Air Corps. The Swedish Volunteer Air Corps (, FFK) is a voluntary defence organization of some 2,400 members (2013) distributed throughout Sweden. The pilots receive their initial training either through privately funded pilot licenses , through the Armed Forces or with bigger schools. Pilots in the FFK perform on a voluntary basis, assignment for Swedish authorities and the Armed Forces. FFK's headquarters are located at Stockholm Västerås Airport.

The FKK is part of Sweden's Total Defence policy, and as such operate in both civilian and military capacities. The aircraft used are largely externally privately owned or joint venture in the Swedish aviation clubs and consist mainly of general utility aircraft, such as the Cessna 172 and Piper PA-28.

Flight Missions
In 2013 the FFK carried out air missions at regional and national level. FFK's civil air groups conducted missions including power line control after storm damage and searching for missing persons with the police.

Young Pilots
The FFK conducts youth activities focusing on flying experiences for young people within the organization 'Young Pilots'. Business and recruitment is carried out mainly through the summer in different places across Sweden. Organizational activities during the remainder of the year are held in the regional and youth-led associations.

Lumped damage mechanics. Lumped damage mechanics or LDM is a branch of structural mechanics that is concerned with the analysis of frame structures. It is based on continuum damage mechanics and fracture mechanics. It combines the ideas of these theories with the concept of plastic hinge LDM can be defined as the fracture mechanics of complex structural systems. In the models of LDM, cracking or local buckling as well as plasticity are lumped at the inelastic hinges. As in continuum damage mechanics, LDM uses state variables to represent the effects of damage on the remaining stiffness and strength of the frame structure. In reinforced concrete structures, the damage state variable quantifies the crack density in the plastic hinge zone; in unreinforced concrete components and steel beams, it is a dimensionless measure of the crack surface; in tubular steel elements, the damage variable measures the degree of local buckling The LDM evolution laws can be derived from continuum damage mechanics or fracture mechanics. In the latter case, concepts such as the energy release rate or the stress intensity factor of a plastic hinge are introduced. LDM allows for the numerical simulation of the collapse of complex structures with a fraction of the computational cost and human effort of its continuum mechanics counterparts. LDM is also a regularization procedure that eliminates the mesh-dependence phenomenon that is observed in structural analysis with local damage models. In addition, LDM method has been implemented in the finite element analysis of crack propagation of steel beam-to-column connections subjected to ultra-low cycle fatigue.

Raymond Pearlson. Raymond Pearlson (born 2 March 1926) is an American marine engineer and the inventor of the Syncrolift System, which was designed to both launch ships and lift them out of the water for repair.

Biography
Pearlson was born in 1926 in New York City. After three years war service in the Navy he studied naval architecture and marine engineering at the University of Michigan, graduating in 1949 with a B.Sc. degree.

He started his engineering career with the Newport News Shipbuilding and Dry-dock Company, spending the next few years working in various yard departments where he acquired a lot of practical shipbuilding knowledge. In 1953 he moved to work as Chief Engineer at Merrill Stevens, a small shipyard in Miami, Florida, where he was entrusted with the construction of a 300-ton lifting capacity boatlift and transfer system. During the process he developed an innovative drydocking concept using simple electro-mechanical components to overcome the inherent limitations of lifting capacity and size.

In 1957, he designed and built the first Syncrolift shiplift with a lifting capacity of 100 tons, and in 1958 formed Pearlson Engineering Company (PECO) to develop his invention. PECO was taken over in 1959 by the British engineering group Northern Engineering Industries, which later became part of Rolls-Royce plc. PECO became NEI Syncrolift, Inc. in 1986. In 1990 Pearlson and his son Douglas, President of the company, both left to form Pearlson and Pearlson, a shipyard consultancy specializing in drydocking and transfer systems.

Pearlson received the 2002 Elmer A. Sperry Award for the invention, development and worldwide implementation of the Synchrolift system.

Fluentd. Fluentd is a cross-platform open-source data collection software project originally developed at Treasure Data.  It is written primarily in the C programming language with a thin-Ruby wrapper that gives users flexibility.

Overview 
Fluentd was positioned for "big data," semi- or un-structured data sets. It analyzes event logs, application logs, and clickstreams. According to Suonsyrjä and Mikkonen, the "core idea of Fluentd is to be the unifying layer between different types of log inputs and outputs.", Fluentd is available on Linux, macOS, and Windows.

History 

Fluentd was created by Sadayuki Furuhashi as a project of the Mountain View-based firm Treasure Data. Written primarily in Ruby, its source code was released as open-source software in October 2011. The company announced $5 million of funding in 2013.
Treasure Data was then sold to Arm Ltd. in 2018.

Users 

Fluentd was one of the data collection tools recommended by Amazon Web Services in 2013, when it was said to be similar to Apache Flume or Scribe. Google Cloud Platform's BigQuery recommends Fluentd as the default real-time data-ingestion tool, and uses Google's customized version of Fluentd, called google-fluentd, as a default logging agent.

Fluent Bit 
Fluent Bit is a log processor and log forwarder which is being developed as a CNCF sub-project under the umbrella of Fluentd project. Fluentd is written in C and Ruby and consumes at least sixty megabytes of memory. Fluent Bit is written only in C, with no dependencies, and consumes approximately one megabyte of memory, making it easier to run under embedded Linux and in containers.

Global Combat Support System. The Global Combat Support System (GCSS) is a web-based automated logistics system, for use by U.S. Department of Defense logistics specialists. This tool aids the specialists as they plan, and provide for, the materiel requirements for combat support.

Northrop Grumman performed the work on the Army version of the system, which is known as GCSS-Army.

This web-based system provides the current status of requisitions. For example, if replenishment supplies were requested, GCSS provides updates of the current location of those supplies, with their expected time of arrival. It replaces SARSS, the standard Army retail supply system interface.

Global Combat Support Systems-Marine Corps (GCSS-MC) has updated its capability with its own software development, in-house.

Effectiveness 

A GAO report estimates that the Army will achieve $11.8 billion in savings and financial benefits.

Tablets for GCSS 

Tablet computers with bar code readers will be used in the Army GCSS for tracking logistics, supplies, and finances.
