Appalachian-class command ship. The Appalachian-class command ship was a ship class of command ships of the United States Navy during World War II. All 4 ships were converted from the Type C2-S-B1 cargo ships.

Development 
Four type C2 cargo ships were converted into command ships for the United States Navy throughout the middle stages of World War II. After the war, all were slightly modernized and decommissioned in 1947 to later scrapped.

The ship's hull remained nearly the same but with new equipment to carry out her purpose now placed on deck alongside several cranes. The ships' armaments had been slightly changed and relocated in order for the ships to carry out their new roles. All ships served in the Pacific Theater until the end of the war with no ships lost in combat.

Block-matching and 3D filtering. Block-matching and 3D filtering (BM3D) is a 3-D block-matching algorithm used primarily for noise reduction in images.  It is one of the expansions of the non-local means methodology. There are two cascades in BM3D: a hard-thresholding and a Wiener filter stage, both involving the following parts: grouping, collaborative filtering, and aggregation. This algorithm depends on an augmented representation in the transformation site.

Method

Grouping 
Image fragments are grouped together based on similarity, but unlike standard k-means clustering and such cluster analysis methods, the image fragments are not necessarily disjoint. This block-matching algorithm is less computationally demanding and is useful later on in the aggregation step. Fragments do however have the same size.
A fragment is grouped if its dissimilarity with a reference fragment falls below a specified threshold.
This grouping technique is called block-matching, it is typically used to group similar groups across different frames of a digital video, BM3D on the other hand may group macroblocks within a single frame.
All image fragments in a group are then stacked to form 3D cylinder-like shapes.

Collaborative filtering 
Filtering is done on every fragments group. A  dimensional linear transform is applied, followed by a transform-domain shrinkage such as Wiener filtering, then the linear transform is inverted to reproduce all (filtered) fragments.

Aggregation 
The image is transformed back into its two-dimensional form. All overlapping image fragments are weight-averaged to ensure that they are filtered for noise yet retain their distinct signal.

Extensions

Color images 
RGB images can be processed much like grayscale ones. A luminance-chrominance transformation should be applied to the RGB image. The grouping is then completed on the luminance channel which contains most of the useful information and a higher SNR. This approach works because the noise in the chrominance channels is strongly correlated to that of the luminance channel, and it saves approximately one-third of the computing time because grouping takes up approximately half of the required computing time.

Deblurring 
The BM3D algorithm has been extended (IDD-BM3D) to perform decoupled deblurring and denoising using the Nash equilibrium balance of the two objective functions.

Convolutional neural network 
An approach that integrates a convolutional neural network has been proposed and shows better results (albeit with a slower runtime). MATLAB code has been released for research purpose.

IncludeOS. IncludeOS is a minimal, open source, unikernel operating system for cloud services and IoT, developed by Alf Walla and Andreas Åkesson. IncludeOS allows users to run C++ applications in the cloud without any operating system.

IncludeOS runs on virtual machines like Linux KVM, and VMWare ESXi/Fusion.

IncludeOS applications boot in about 300 ms. On Solo5/uKVM from IBM Research, boot times as low as 10 milliseconds are possible.

Architecture
The minimalist architecture of IncludeOS means that it does not have any virtual memory space. In turn, therefore, there is no concept of either system calls or user space.

Technology mining. Tech mining or technology mining refers to applying text mining methods to technical documents. For patent analysis purposes, it is named ‘patent mining’. Porter, as one of the pioneers in technology mining, defined ‘tech mining’ in his book as follows: “the application of text mining tools to science and technology information, informed by understanding of technological innovation processes.” Therefore, tech mining has two significant characteristics: 1) using ‘text mining tools’, 2) applying these tools to ‘technology management’. Also, technology mining can be considered as one of technology intelligence branches.

Applications 
Technology mining have many applications including R&D portfolio selection, R&D project initiation, new product development, strategic technology planning, technology roadmapping, etc. Tech miner should communicate closely with target users what technological issue they have, and how they want to address the issues. The number of published papers and the number of citations in technology mining area illustrates a hyperbolically progress; there is a jump in the number of publications after 2005 and a huge rise in the number of citations after 2012.

Clive Lee. Alan John Clive Lee (18 February 1939 – 2 November 2021) was a British design engineer known for co-creating the Exeter hip system in association with orthopaedic surgeon, Robin Ling. Unlike any other hip replacement, the collarless polished tapered cemented hip stem became the most widely used cemented total hip joint in the National Health Service.

Early life 
Clive Lee was born in February 1939. He was schooled in Solihull, England. Whilst working as an apprentice for Rolls-Royce, he studied mechanical engineering at the University of Nottingham, subsequently receiving a first class honours degree in 1961.

Career 
In 1966, Lee was appointed assistant lecturer at University of Exeter.  He went on to become fellow in the School of Engineering, Computing and Mathematics in Exeter. He has published widely in academic British and international journals. In 2020, Lee was made a Professor by the University of Exeter. 

"We were proud to name the hip after Exeter as so many people in the University and the hospital were instrumental in its development. We had significant technical and other support from the University's former department of Engineering Science.... Still the biggest pleasure for me is when people who have had replacement hips come up to me and thank me for changing their lives." - quoted by Lee sometime after 2010.

In 2010, the millionth Exeter hip was implanted. It became the most widely used hip replacement worldwide.

Personal life 
Lee lived in Exeter with his wife, Pamela. They had two children; a son and a daughter. Both graduated from the University of Nottingham in engineering disciplines. He died on 2 November 2021, at the age of 82.

Grampian 28. The Grampian 28 is a Canadian sailboat, that was designed by Rolf van der Sleen and first built in 1975.

Production

The boat was built by Grampian Marine in Oakville, Ontario, Canada starting in 1975 and 107 examples were completed, but it is now out of production.

The Grampian 28 design was later developed into the Intrepid 28 and built by Intrepid Yachts, a division of Cape Dory Yachts, using the same tooling.

Design
The Grampian 28 is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a masthead sloop rig, a skeg-mounted rudder and a fixed fin keel. It displaces  and carries  of ballast.

The boat has a draft of  with the standard keel fitted and  with the optional shoal draft keel.

The design is fitted with a Swedish Volvo diesel engine. The fuel tank holds  and the fresh water tank has a capacity of .

The boat has a PHRF racing average handicap of 195 with a high of 186 and low of 204. It has a hull speed of .

Operational history
In a review Michael McGoldrick wrote, "The Grampian 28 is more contemporary and nicer looking than the other Grampian models... Although it has a fairly high freeboard, it doesn't have the spoon-bow which is characteristic of some other Grampian models. While this 28 footer may not be as plentiful as either the Grampian 26 or 30... This boat has a nice interior layout which includes a quarter berth."

J. E. Greiner Company. J. E. Greiner Company was a Baltimore, Maryland-based civil engineering firm specializing in bridge design.

History

The firm was founded in 1908 by former Baltimore and Ohio Railroad bridge engineer John Edwin Greiner (February 24, 1859 – November 15, 1942) and led by Greiner and his associate Hershel Heathcote Allen. The firm was later known as Greiner Engineering and opened a second office in Chicago, apparently in connection with its work on the Calumet Skyway. In 1995, the firm was acquired by URS Corporation, now part of AECOM.

The firm designed several notable bridges and also prepared transportation planning studies, the first of which was Maryland's Primary Bridge Program for the Maryland State Roads Commission in 1938. Later studies included Transportation Plans for Washington for Washington, D.C. in 1946, and Expressway System for Metropolitan Providence for Rhode Island, in 1947, both with De Leuw, Cather & Company.
