Center for Advanced Public Safety. The Center for Advanced Public Safety (CAPS) is part University of Alabama College of Engineering and specializes in advanced software research and development to assist traffic safety, law enforcement and homeland security.

History 

Formerly known as the CARE Research and Development Laboratory (CRDL), CAPS has its historical roots in information technology development to advance traffic safety.  This originated with the Critical Analysis Reporting Environment (CARE) that was initially developed to assist moderate sized cities process their traffic crash records in the mid to late 1980s on CPM-based microcomputers.  CARE has undergone continuous innovation over the years and is now in its tenth major version upgrade, while becoming a component of the enterprise traffic safety data system in 12 different states.

In 2017, CAPS was awarded approx. US $1.8m in funding by Governor Kay Ivey. The grants were administered through the Alabama Department of Economic and Community Affairs (ADECA).

Projects 
App Development: CAPS participated in the development of an app, HYPE, which helps people manage their blood pressure and is available, for free, to Apple and Android users.

Severe Weather Study: CAPS put out a call for volunteers to participate in a study “to see how people prepare and react to severe weather events.” Participants will be interviewed before, during, and after any “bad weather events during the 2021 Spring weather season.”  The study is part of a federally-funded tornado study the University of Alabama is doing with the University of Oklahoma.

Collaborative network. A collaborative network is a network consisting of a variety of entities (e.g. organizations and people) that are largely autonomous, geographically distributed, and heterogeneous in terms of their operating environment, culture, social capital and goals, but that collaborate to better achieve common or compatible goals, and whose interactions are supported by computer networks. The discipline of collaborative networks focuses on the structure, behavior, and evolving dynamics of networks of autonomous entities that collaborate to better achieve common or compatible goals.
There are several manifestations of collaborative networks, e.g.:
 Virtual enterprise (VE)
 Virtual Organization (VO)
 Dynamic Virtual Organization
 Extended Enterprise
 VO Breeding environment (VBE)
 Professional virtual community (PVC)
 Business Ecosystem
 Virtual manufacturing network
 Decentralized Autonomous Organization (DAO)

Applications

Elements 
The seven essential elements of collaborative networks:
 
 Search: Allowing users to search for experts, data or content
 Employee Driven: Approved users can add and share content in wiki fashion with low barriers to authorship
 Data integration: Must allow enterprise data to be integrated into the system
 Dashboards and Monitoring: Measure success, adoption, projects through dashboards and monitoring tools
 User Follow: Ability to follow users and their content in the collaborative network
 Content integration: Connects and links content dynamically
 Governance: Controlled access to content and data

Reference models 
A reference model for collaborative networks is a fundamental instrument for the smooth development of the area. An example of reference model is ARCON (A Reference model for COllaborative Networks).
An annual conference focused on Collaborative Networks is the Working Conference on Virtual Enterprises ('PRO-VE'). sponsored by the International Federation for Information Processing (IFIP) and Society of Collaborative Networks (SOCOLNET).

Challenges
If collaborative networks evolve and become increasingly popular with corporations and their extended networks, governance and security issues will need to be addressed. Of particular relevance is the study of behavioral aspects and reference models for collaborative networks.

Strap wrench. A strap wrench is any of various types of wrench that grip an object via a strap or chain being pulled in tension around it until it firmly grips. High static friction keeps it from slipping. 

Many strap wrenches have built-in handles. Others are made to receive the square drive of a ratchet wrench. 

The strap or chain can have various forms. Some straps are made of polymers, and are smooth, highly flexible, non-marring, high-friction straps. (Before the era of commercial polymers, the straps were of leather or rubber.) Other straps are bands of spring steel, moderately flexible, slightly firmer and more likely to mar than the polymer variants. The chains tend to be of the roller chain type (like a bicycle chain).

Types

Oil-filter wrenches
Many oil-filter wrenches are actually strap wrenches. Others are of the socket type or the pliers type.

Chain whips (e.g., for bicycle work)
A chain whip is a tool used to tighten and loosen threaded sprockets on a bicycle. It is called a chain whip because it has a short section of chain used to grip the sprocket. An alternative method to tighten sprockets is the rotafix method, which uses no tools.

Piston-ring compressors
Piston-ring compressors are strap wrenches that evenly squeeze (compress) the piston rings around a piston long enough to slide it into a cylinder. They look a lot like an oil-filter wrench of the strap type (except they are a flat piece of metal that wraps around the piston).  If no wrench is available, an old piston ring snapped into two halves can be used to compress each of the new rings as the piston is inserted.

Natural Sequence Farming. Natural Sequence Farming (NSF) is a method of landscape regeneration devised by the Australian farmer, Peter Andrews, in the 1970s.

The method involves implementing major earthworks on a given area of land that has been devastated by deforestation and general agricultural activities, to emulate the role of natural watercourses in an effort to reverse salinity, slow erosion and increase soil and water quality to enable native vegetation to regenerate and restore the riparian zone.

The method does not require the use of artificial fertilisers or herbicides.

Flood control
Flood events may occur only once every 1 or 2 years; however, they have the ability to enhance or destroy a property. If the waters move too fast over bare land, then they can strip away topsoil and nutrients, leaving behind barren sands. By inserting barriers across creeks and encouraging water to spread outwards, the energy of a flood is reduced, the currents tend to deposit soil from upstream, and the water can soak into the land. This encourages grasses and fast-growing plants to take root.

The role of weeds
Ground cover protects the land from drying and baking, and also stabilises the land in future flood events. While rye and other grasses have long been seen as beneficial crops for grazing, other plants that have been considered weeds can improve the soil, augment the growth of other crops, and assist the diet of grazing animals. These 'weeds' should not be removed. When they die naturally, they should be cut for feed or used as green manure.

Many 'weeds' thrive in only the regenerative cycle. Once the land recovers fertility, the weeds tend to be replaced naturally by trees.

Fraudulent NSF
Since the 1990s, there have been a number of cases where individuals or groups have sought financial gain through offering fraudulent versions of NSF.

Gateway to Strangeness. "Gateway to Strangeness", also titled "Dust of Far Suns" and "Sail 25", is a science fiction novelette by American writer Jack Vance. It was first published in the August 1962 issue of Amazing Stories magazine.

Plot
Eight space trainees apprehensively await their new instructor, Henry Belt. Despite the many strange and outrageous stories they have heard about him, including his legendary drunkenness, one of them notes that all of the top men in space seem to have trained under him.

Since only six trainees can go on the space journey, Belt first assigns each man the task of building three specific devices using identical piles of assorted parts. The two men who become the most frustrated by the nearly impossible tasks are dropped. The others board a small spaceship (Sail 25) propelled solely by a solar sail for a flight to Mars. Belt leaves the navigation entirely in their hands. All the while, he makes careful note of their faults (according to his idiosyncratic standards), recording their demerits in his little red book.

However, a mistake repairing a malfunctioning computing device causes them to miss their rendezvous, first with Mars, then with Jupiter. No other planet whose gravity could halt their outward flight (their solar sail can only propel them away from the Sun) is within reach. Belt dismantled their radio and the box of spare parts turns out to contain Belt's whiskey, so they cannot call for rescue. It seems that they are doomed. One man commits suicide, while two others become catatonic. Henry Belt insists that he is fated to die in space and offers no way out of their predicament.

The three remaining men eventually come up with a way to return safely to Earth. As they prepare to debark, spare parts for the computing device mysteriously appear.

Akaflieg Stuttgart F.1. The Akaflieg Stuttgart F-1 Fledermaus (Bat) was a glider designed and built in Germany from 1932.

Development 
The 'F.1' was the first glider designed and built at Akaflieg Stuttgart (Akademische Fliegergruppe) using a wind tunnel and innovative thinking. As built, the F.1 had no vertical tail, using rotatable wing-tip panels for roll and yaw control. The fuselage was curved to follow the downwash from the wing and rested solely on a single large skid under the forward fuselage, not having a tail-skid.
The completely enclosed cockpit included a hanging control column, to simplify the control run, and airbrakes, for use on the ground, using the cockpit canopy.
The F.1 entered its first competition at Rhön in 1933, but the technical committee insisted that the glider be given a conventional vertical tail, despite protests that the F.1 had already flown a 300 km distance task as built. The fliegergruppe acquiesced and built a vertical tail overnight, with the F.1 claiming several prizes during the competition.

Paldang Bridge. The Paldang Bridge (; ) crosses the Han River in South Korea and connects the cities of Hanam and Namyangju. Excluding the single-lane bridge built on top of the Paldang Dam, it is the easternmost bridge on the Han River.

Construction on the bridge began in May 1986 as the second concrete bridge over the Han River after Olympic Bridge. Construction was halted in March 1991, however, when a portion of the bridge collapsed due to strong winds and killed one construction worker on site. Inspections revealed structural damage, prompting a change in construction methods. Construction resumed in October 1991, but was halted again in May 1992 after further structural damage was discovered. Initial designs were scrapped, and the bridge was opened as a girder bridge on April 25, 1995.

Computer-aided inspection. Computer-aided inspection (CAI) is the use of software tools to assess manufactured objects. It is closely related to computer-aided design (CAD) and computer-aided manufacturing (CAM). Its primary purpose is to allow engineers to more quickly and precisely assess the physical properties of manufactured objects. These properties can include dimensions, material consistency, roughness and roundness.

Uses
CAI has applications in industries ranging from food production to aerospace, commonly being used in the quality assurance step of the manufacturing process. It involves comparing manufactured objects with a CAD model, technical drawing or data sheet to ensure that the finished product is within specification and meets design intent.

Technologies
CAI machines can use a variety of technologies depending on the material of the product to be inspected, the properties to be measured, and the precision required.

Digital Cameras
Digital cameras are frequently used in situations where the shape or colour of an object needs to be analysed. Using machine vision, the CAI program can make decisions about objects by comparing them to a master photo or data array.

Laser Scanning
Laser scanning CAI machines use point clouds to generate a 3D model which is compared to the required specification. Laser scanners are generally used to check the external geometry of parts with low reflectivity and translucence.

Structured Light Scanning
Structured light scanners use projected light patterns and digital cameras to analyse the geometry of an object. As with laser scanning, objects with high reflectivity and translucence can cause problems but temporary coatings can be applied to prevent this.

CT Scanning
Industrial CT scanners use X-rays to image an object from many angles, building up a 3D image to compare to a specification. CT scans can be used to analyse the internal geometry of parts because the X-rays penetrate the object being scanned. Higher resolution CT scans can also check for cavities, cracks, and other undesirable features inside parts.

Lockheed Big Dipper. The Lockheed Model 34 Big Dipper was an American two-seat monoplane, designed and built by Lockheed at Burbank for research into the company's potential entry into the civil lightplane and military light utility aircraft market. Only one was built, and following its loss in an accident the program was abandoned.

Design and development
Developed by John Thorp and based on his work on Lockheed's Little Dipper lightplane project, the Lockheed Model 34, named "Big Dipper", was intended as a prototype for a lightplane to sell on the postwar market - Lockheed hoping to sell the aircraft at a price of $1500 - and as a potential 'flying jeep' for the United States Army. It was a low-wing cantilever monoplane with a fixed tricycle landing gear and a conventional empennage; the cabin was enclosed, seating two in side-by-side positions. Unusually the Continental C100 piston engine was fitted in the center fuselage behind the cabin, driving a two-bladed pusher propeller mounted at the rear of the aircraft.

Operational history
The Model 34 was built at Burbank from July 1945. To keep the project secret the aircraft was moved to Palmdale by road when completed, flight testing being conducted at Muroc Dry Lake. It first flew on 10 December 1945, and after 40 hours of flight testing was returned to Burbank for modifications, intended to correct a wing-root stall issue that had been identified. It was decided not to complete the modification, and the aircraft was to be flown back to Palmdale on 6 February 1946. To try to keep the Big Dipper secret, it was decided to use a shorter upward sloping runway nearer the factory; in the steep climb needed during takeoff from the shorter runway, the aircraft stalled and crashed. With the loss of the prototype, and the fact the expected rush of buyers for new lightplanes was failing to materialize amidst a glut of war-surplus aircraft, the project, and a proposed high-wing four-seat "Super Dipper" derivative, was abandoned;
