OptQuest. OptQuest is an optimization software developed by OptTek Systems, Inc., used to tackle complex optimization problems through Simulation-based optimization (SBO). It primarily integrates with commercial simulation software to improve decision-making and optimization in scenarios characterized by stochastic behavior and complexity.

Underlying algorithms 
Like other optimization packages and SBO products, OptQuest utilizes metaheuristic algorithms. Among them, OptQuest uses:

 Tabu search
 Scatter search 

OptQuest, like practically all software packages for simulation-based optimization, utilizes iterative heuristics and approaches the simulation model as a black box, meaning it only interacts with the model through its input and output data.

Software integration 
OptQuest was initially released in 1998 as a spinout of the University of Colorado Boulder to be used with Crystal Ball simulation software (Decisioneering Inc.). OptQuest is frequently used as a plugin with various commercial simulation software to provide optimization capabilities (simulation-based optimization). These include:

 AnyLogic since 2002 
 Arena
 FlexSim
 SIMUL8

Alternatives 
Simulation software ProModel integrates with optimization package SimRunner, which is based on genetic algorithms. Witness optimizer uses tabu search and simulated annealing algorithms.

Wind Demon. Wind Demon is an Israeli long-range air-to-surface cruise missile developed by IAI. The missile is designed to neutralize a wide range of targets at long ranges with minimal resources. The cruise missile was first unveiled at the Farnborough Air Show on 22 July 2024.

An advanced missile equipped with an electro-optical homing warhead that provides high survivability, the Wind Demon is designed to meet the market demand for an effective and relatively inexpensive weapon that can be used for prolonged combat.

Tactical and technical characteristics 
 Flight range: > 200 km
 Weight: 140 kg
 Circular error probable : 1 m
 Guidance System: Electro-Optical (EO), IIR, HD VIS, Semi-Active Laser Homing, ATR and Man-in-the-Loop Control

Description 
The Wind Demon is launched from airborne platforms such as helicopters or fixed-wing aircraft and follows a predetermined mission plan to attack moving or stationary targets at ranges exceeding 200 kilometers. Flying at low altitudes, the Wind Demon avoids detection, disruption, and interception. The missile is capable of engaging both mobile and stationary targets.

Operators can select fast/slow/fast speed profiles that allow them to react to high speeds or approach points of interest at low speed, all designed for the element of surprise and evasiveness.

Indian locomotive class HT. The Indian locomotive class HT (Heavy Tank) were a class of  broad-gauge tank locomotives that were one of seven standard broad-gauge locomotive designs developed by the British Engineering Standards Committee (BESC) (later the British Engineering Standards Association (BESA)) for the broad-gauge railways of British India.

History 
At the turn of the 20th century, the railways in British India utilised numerous classes of locomotives of differing designs, and there was an urgent need of standardisation: British Indian railways looked to non-British locomotive manufacturers to meet their motive power needs since British locomotive manufacturers could not meet them due to the varying degree of locomotive designs used by British Indian railways, generating complaints from British locomotive manufacturers. This resulted in the establishment of a locomotive subcommittee of the British Engineering Standards Committee (BESC) who developed several standardised designs of locomotives between 1903 and 1910 in three successive reports, with the HT class being a later addition to the third report of the BESC in 1910. This design was similar to locomotives delivered in 1921 to the Bengal Nagpur Railway (BNR), which were made using parts shared with other BESC designed locomotives. The HT class had the same cylinder dimensions as the HGS/HGC class (HG (Heavy Goods) class locomotives converted to or installed new with superheating)  locomotives, whereas the boiler was shared with the PT class (Passenger Tank)  locomotives.

During the 1920s, Beyer, Peacock & Co. delivered locomotives of this design for the North Western Railway and the East Indian Railway. Some were in active service as of 1978, allocated to the Dhanbad and Pathardth sheds of Eastern Railways.

Easby Abbey Mill. Easby Abbey Mill is a historic building in Easby, a village near Richmond, North Yorkshire, in England.

Easby Abbey had a watermill constructed in the mid-12th century, on a site northwest of the abbey buildings.  It had a mill race linked to the River Swale. Rebuilt around 1800, the mill retained the original foundations, and included a residence for the miller.  In the 20th century, its purpose shifted from grinding corn to generating electricity for the village, via a turbine which operated until the 1950s. Later, it was converted into a dwelling.

The mill is constructed from stone, featuring quoins, a stone slate roof, stone gable copings and shaped kneelers. It boasts two storeys and six bays. The front facade includes a doorway with a stone surround on plinths, adorned with imposts, voussoirs, a semicircular arch, and a tripartite keystone.  The windows are sashes. The mill has held grade II listed status since 1986.

1974 Francistown Wenela Air Services Douglas DC-4 crash. The 1974 Francistown Wenela Air Services Douglas DC-4 crash occurred on April 4, 1974. On this day, a Douglas DC-4 operated by Wenela Air Services, conducting an international scheduled flight from Francistown Airport in Botswana to Chileka Airport in Malawi, was forced to make an emergency landing due to engine failure, resulting in the death of 78 out of 84 people on board. This incident remains the deadliest aviation accident in Botswana and the third deadliest involving a Douglas DC-4.

Aircraft 
The aircraft was the 240th Douglas DC-4 off the production line. The machine was assembled in 1944 as the military version C-54B at the Douglas Aircraft Company factory in Santa Monica, California, and subsequently delivered to the United States Army Air Forces (USAAF). After World War II, the machine was categorized as surplus by the USAAF and decommissioned. The Douglas Aircraft Company purchased the machine on December 13, 1945, and converted it to a civilian DC-4. On April 2, 1946, the machine was sold to Delta Air Lines, where it operated until February 1953. After flying for several years with other airlines, in June 1959 it was sold to the Witwatersrand Native Labour Association (WNLA), a mining company managing gold mines in South Africa, also known as Wenela. The company was involved in recruiting migrant workers and owned a fleet of buses and aircraft stationed in all the countries of Southern Africa. The machine was registered firstly in South Africa, then in Rhodesia, and finally in Botswana as A2-ZER, to (Wenela Air Services Botswana). The four-engine long-range aircraft was equipped with four radial engines of the type Pratt & Whitney R-2000-2SD-13G Twin Wasp.

Passengers and crew 
At the time of the accident, there were 80 passengers and four crew members on board. Most of the passengers were employees of the South African mining company, returning home.

Accident sequence 
The accident occurred at 02:35 local time. Shortly after taking off from Francistown Airport, the aircraft experienced misfires and ignition failures, leading to a continuous descent. The pilots were unable to gain a safe altitude due to these issues, causing the DC-4 to clip treetops and crash to the ground 3 600 meters past the runway's end after a stall.

Cause 
It was determined that the aircraft had been partially misfueled. Ground personnel mistakenly filled one of the fuel tanks intended for aviation gasoline (Avgas) with kerosene. As a result, the fuel the aircraft was loaded with was contaminated by 25 to 30 percent.
