Herbert Walker (architect). Lieut-Colonel Herbert Walker FRIBA, M Inst CE, FSI, (1846 - 23 November 1937) was an architect, surveyor and civil engineer based in Nottingham from 1870 to 1923.

Life
He was born in 1846, the son of George Frederick Walker (1800 - 1857) and Eliza Dutton (1807 - 1875).

He studied in the office of his brother Samuel Dutton Walker from 1860 - 1866. He was then articled to Borough Engineer Marriott Ogle Tarbotton from 1866 - 1870 and was engineer and surveyor to Basford Sanitary Authority. When Basford was merged with Nottingham he started his own practice in Nottingham in 1870. He had offices in Newcastle Chambers on Angel Row until around 1907 when he moved to Albion Chambers in King Street.

He was appointed a Fellow of the Royal Institute of British Architects in 1889.

He married Annie Sophia Turner, youngest daughter of John Turner of Edwalton, on 25 January 1872 at Holy Rood Church, Edwalton and they had the following children:
Ethel Walker (b. 1873)
Mabel Elizabeth Walker (b. 1878)
Herbert Spencer Walker (1882 - 1906)
Frederick Turner Walker (1883 - 1941)
Marion Walker (b. 1884)
Dorothy Annie Walker (1889 - 1909)
Kathleen Marjorie Walker (b. 1892)
Geoffrey Dutton Walker (became Manchester City Surveyor)

Until 1886 he lived in a house called Church Fields, in Bailey Street, Old Basford.

He spent about 37 years with the Robin Hood Battalion which he joined in 1864 as a cadet. He retired with the rank of Lieut-Colonel. During the First World War he undertook recruiting work and was appointed inspector of machinery for the Royal Engineers.

For seven years, he was church warden at Emmanuel Church, Nottingham.

On retiring from business in 1923 he moved to Blackpool. His wife predeceased him by ten years and he died on 23 November 1937.

Theodor Schultes. Theodor Schultes or Theodor Jakob Joseph Schultes (1901-1981) was a German engineer of radio frequency technology and a pioneer of radar technology . His best known developments include the radio measuring devices with the code names Freya, Aquarius and Jagdschloß.

Education
Schultes, born the son of a savings bank director, attended high school in Völklingen until he graduated from high school. After one year of practical work at the Röchling factories, he studied electrical engineering at the Technical University of Darmstadt from 1921 to 1926. He then worked there as a research assistant, from 1929 to 1933 as an assistant, and in 1934 he did his doctorate in electrical engineering and information technology.

Career
In 1933 he moved to Berlin and continued his research in the area of room acoustics at the Heinrich Hertz Institute for Vibration Research. As early as June 1934, he moved to the newly founded Society for Electro-Acoustic and Mechanical Apparatus (GEMA) to take over the management of the research laboratory.

Here, Schultes and his team developed the first practical radio measuring devices. An essential task was the development of suitable transmitter tubes.

In 1937, after further extensive tests, Schultes developed the Freya radio measuring device . It worked with a wavelength of 240 centimeters, was portable and intended for the detection of flight destinations. Freya had a range of around 100 kilometers. Another of Schulte's inventions was the Jagdschloß panoramic viewer, which was constructed in 1943 . It was used to display all aircraft on a large display board, which were located in the air space, which was electronically scanned up to 150 kilometers away.

The Oyster Question. The Oyster Question: Scientists, Watermen, and the Maryland Chesapeake Bay since 1880 is a 2009 book by Christine Keiner. It examines the conflict between oystermen and scientists in the Chesapeake Bay from the end of the nineteenth century to the present, which includes the period of the so-called "Oyster Wars" and the precipitous decline of the oyster industry at the end of the twentieth century. The book engages the myth of the "Tragedy of the Commons" by examining the often fraught relationship between local politics and conservation science, arguing that for most of the period Maryland's state political system gave rural oystermen more political clout than politicians and the scientists they appointed and allowing oystermen to effectively manage the oyster bed commons. Only towards the end of the twentieth century did reapportionment bring suburban and urban interests more political power, by which time they had latched on to oystermen as elements of the area's heritage and incorporated them and the oysters into broader conservation efforts.  An important theme is the "intersection[] of scientific knowledge with experiential knowledge in the context of use," in that Keiner "treats the knowledge of the Chesapeake Bay’s oystermen alongside that of biologists." "Through her analysis, Keiner effectively reframes how environmental historians have analyzed histories of common resources and provides a working model for integrating historical and ecological information to bridge the histories of science and environmental history."

Awards 
The book won the 2010 Forum for the History of Science in America Prize.  It shared the 2010 Maryland Historical Trust's Heritage Book Award, and received an Honorable Mention for the Frederick Jackson Turner Award from the Organization of American Historians in 2010.

Trac 14. The Trac 14 is an American catamaran sailing dinghy that was designed by Australians Richard McFarlane and Jay McFarlane as a one-design racer and first built in 1980.

The design is a licensed version of the 1976 Windrush 14, which was originally known as the Surfcat and built by Windrush Catamarans of Australia. The Trac 14 is  heavier than the Windrush 14.

Production
The Trac 14 design was built under license from Windrush Catamarans by the AMF Alcort division of AMF, Inc. in the United States. The company commenced production in 1980 and produced 1500 by the time it went out of business in 2012.

Design
The Trac 14 is a recreational sailboat, built predominantly of fiberglass. It has a fractional sloop rig with hard-coated aluminum spars. The mainsail has seven full sail battens. The dual hulls have spooned raked stems, plumb transoms, dual transom-hung rudders controlled by a tiller, equipped with a hiking extension. The boat displaces .

The boat has a draft of . The hulls have no keels and instead rely on their curved shape to reduce leeway. This hull arrangement allows easy beaching. The hulls fold under the trampoline to reduce the beam to  for ground transportation on a trailer.

For sailing the design is equipped with a three-part downhaul and a roller furling jib. There is no trapeze, but the mast rake is adjustable while sailing.

The design has a Portsmouth Yardstick racing average handicap of 83.5 and is normally raced with a crew of two sailors.

ANASIS-II. ANASIS-II (Army Navy Air Force Satellite Information System-II), formerly called "KMilSatCom 1", is a South Korean military/government communications satellite which was launched on 20 July 2020. It was built by Airbus Defence and Space as part of an offset package into the purchase of 40 F-35 combat aircraft.

Launch
The payload was launched aboard a reused 1st stage booster, B1058 featuring the NASA "worm" logo, which previously launched SpaceX DM-2. After stage separation it successfully landed aboard the drone ship Just Read the Instructions in the Atlantic Ocean. Both fairing halves were successfully caught by recovery ships Ms. Tree and Ms. Chief, making it the first successful catch attempt in which both halves were caught for reuse.

Operation
In October 2020, the Chosun Ilbo reported that South Korean Armed Forces had not developed the ground segment of ANASIS-II yet. It is likely that ANASIS-II will not be utilized for more than a year.

Whole Atmosphere Community Climate Model. The Whole Atmosphere Community Climate Model (WACCM) is used to generate computer simulations of the dynamic processes interacting between the terrestrial and solar systems that impact on Earth's climate. The original model was developed around the turn of the millennium with the most recent iteration, version 6 (WACCM6), released in 2019. The Whole Atmosphere Community Climate Model with thermosphere and ionosphere extension (WACCM-X) extends the model to space weather and space climate.

2.5D integrated circuit. A 2.5D integrated circuit (2.5D IC) is an advanced packaging technique that combines multiple integrated circuit dies in a single package without stacking them into a three-dimensional integrated circuit (3D-IC) with through-silicon vias (TSVs). The term "2.5D" originated when 3D-ICs with TSVs were quite new and still very difficult. Chip designers realized that many of the advantages of 3D integration could be approximated by placing bare dies side by side on an interposer instead of stacking them vertically. If the pitch is very fine and the interconnect very short, the assembly can be packaged as a single component with better size, weight, and power characteristics than a comparable 2D circuit board assembly. This half-way 3D integration was facetiously named "2.5D" and the name stuck.
Since then, 2.5D has proven to be far more than just "half-way to 3D."
Some benefits:
 An interposer can support heterogeneous integration – that is, dies of different pitch, size, material, and process node.
 Placing dies side by side instead of stacking them reduces heat buildup.
 Upgrading or modifying a 2.5D assembly is as easy as swapping in a new component and revamping the interposer to suit; much faster and simpler than reworking an entire 3D-IC or System-on-Chip (SoC).
Some sophisticated 2.5D assemblies even incorporate TSVs and 3D components. Several foundries now support 2.5D packaging.
The success of 2.5D assembly has given rise to "chiplets" – small, functional circuit blocks designed to be combined in mix-and-match fashion on interposers. Several high-end products already take advantage of these LEGO-style chiplets; some experts predict the emergence of an industry-wide chiplet ecosystem. Interposers can be larger than the reticle size which is the maximum area that can be projected by a photolithography scanner or stepper.

Daimler Motor Lastwagen. The Daimler Motor-Lastwagen is the world's first truck, manufactured in the year 1896 by Daimler Motoren Gesellschaft and designed by Gottlieb Daimler.

History
In 1896, Gottlieb Daimler and Wilhelm Maybach began developing a truck with a 1.06-liter two-cylinder four-stroke engine built into the rear, which developed 4 hp (2.9 kW ). The one with hot-tube ignition and injection nozzle carburetor equipped engine was the first prototype built yet behind the rear axle and driving the rear wheels through a four-speed belt drive. The car had turntable steering and a manually operated block brake that acted on the iron tires on the rear wheels. There was also a foot-operated shoe brake on the countershaft. The vehicle was 4.5 m long and 1.5 m wide, the payload was given as 1500 kg, and the top speed was 12 kmph. Its purchase price was 5,200 marks.

On 1 October 1896, Daimler sold the first truck ("Order No. 81") to the British Motor Syndicate in London. In this model, the motor had been enlarged to 1.53 liters with 6 HP (4.4 kW), was installed under the driver's seat. In the same year, Daimler-Motoren-Gesellschaft was the first vehicle manufacturer in the world to launch a model range of various trucks that were available in four different power levels: 2.9 kW, 4.4 kW, 5.9 kW and 7.4 kW. The payloads ranged from 1.2 tons to 5 tons.

According to documents from Daimler were delivered by January 1899 "ten load and thirteen Bierwagen". Customers included the Paul von Maur freight forwarder in Stuttgart and the Bohemian brewery in Berlin, which used the Daimler motor truck as a "beer wear truck".

Electric Loco Shed, Ghaziabad. Electric Loco Shed, Ghaziabad is a motive power depot performing locomotive maintenance and repair facility for electric locomotives of the Indian Railways, located at  of the Northern Railway zone in Uttar Pradesh, India. It is one of the two electric locomotive sheds of the Northern Railway, the others being at Ludhiana (LDH) .

History 
Steam locomotive sheds used to exist at Ghaziabad until the late 1960s. After Northern Railway set a deadline to eliminate all steam locomotive operations by 1990, a push was given towards establishing electric locomotion as the primary motive power, and the Steam locomotive sheds was decommissioned. To meet the needs of exponentially increasing rail traffic on the new continuous broad-gauge lines from Delhi to rest of India with the completion of gauge conversion, the Ghaziabad was selected by Indian railways for a new electric locomotive shed.

New Electric locomotive shed was inaugurated in the late 1976s with WAM-4 which stayed until late 2009, when they were transferred to other sheds. It later got a large fleet of WAG-5 locos, but later these were then moved to Ludhiana. All WAP-1 locos from Arakkonam and Mughalsarai shed were transferred here for hauling rajdhani expresses. The brand new from ABB were directly allocated to ghaziabad after arrival in India. New WAP-7 locos were acquired in 2000s. The shed also held a single WAM-4 units which is earmarked for preservation.

Operations 

Being one of the three electric engine sheds in Northern Railway, various major and minor maintenance schedules of electric locomotives are carried out here. It has the sanctioned capacity of 200 Locos.Expansion work on Progress to 225 Locos.Total 293 Electric locos Holding at GZB ELS,including 137 WAP-5 and 155 WAP-7. It also housed a WAM-4 locomotives temporarily. Electric loco Shed, Ghaziabad is now housing the  largest fleet of WAP-5 in Indian Railways and it caters to many long-distance electric trains.

Like all locomotive sheds, GZB does regular maintenance, overhaul and repair including painting and washing of locomotives. It not only attends to locomotives housed at GZB but to ones coming in from other sheds as well. It has four pit lines for loco repair. Locomotives of Ghaziabad ELS  were the regular links for all trains running through Delhi when widespread electrification of railway lines started in Northern Railways. It handled prestigious trains like  Howrah Rajdhani Express and Mumbai Rajdhani Express. GZB locomotives used to be predominantly the regular links for trains traveling to east as well.

Leonardo Falco Xplorer. The Falco Xplorer is a MALE UAV capable of both intelligence, surveillance, target acquisition, and reconnaissance missions and airstrike missions, developed by Leonardo S.p.A. of Italy. Aimed at military and civilian markets, the drone is not subject to ITAR restrictions making it easily exportable around the world.

Development

The Falco Xplorer was first presented at the Paris Air Show of 2019 by Fabrizio Boggiani, senior vice-president of airborne sensors and mission systems at Leonardo Electronics. On 15 January 2020, the Test Flight Department of the Italian Air Force conducted the first flight of the Xplorer at the Trapani–Birgi Airport. On 22 October 2020 during testing, an unknown problem forced one Falco to be ditched at sea. The Falco Xplorer finished its first round of testing on 22 December 2022, after which it started a new round of testing with the Direzione degli Armamenti Aeronautici e per l'Aeronavigabilità (ARMAEREO) with the objective to meet the NATO STANAG 4671 standard. At the 2023 Paris Air Show, Leonardo presented a version of the Xplorer armed with the Brimstone 3 missile, departing from the 2019's statements that there were no plans to manufacture an armed version of the platform. Leonardo hopes to complete the certification process and start receiving orders by 2024.

MOS Technology file format. The MOS Technology file format is a file format that conveys binary information in ASCII text form.

History 
The KIM-1 single-board computer specified a file format for magnetic tape and a format for paper tape. The paper tape format was adapted slightly and has been used to interchange files for computers based on the MOS Technology 6502 microprocessor.

The open-source Srecord package simplified this tape format by eliminating the  and  characters.

Format 
Each record begins with a semicolon (), followed by two hexadecimal digits denoting the length of the data in the record. The next two bytes represent the starting address of the data, in big-endian (most-significant byte first) hexadecimal. Up to 24 bytes of data follow. Then, there is a 2-byte (4-character) checksum: the sum of the other non- data in the record. Finally, a record ends with a carriage return (), a line break (), and six null characters ().

The last record on the paper tape is empty (its length field is ), with the starting address field representing the total number of data bytes contained in the transmission. The file ends with a .
