Robert Liptser. Robert Sh. Liptser (; , 20 March 1936 – 2 January 2019) was a Russian-Israeli mathematician who made contributions to the theory and applications of stochastic processes, in particular to martingales, stochastic control and nonlinear filtering.

Biography

Liptser was born in Kirovograd, Ukraine and spent his youth in Odesa, Ukraine. In 1959 he graduated with the M.Sc. degree in electrical engineering from Moscow Aviation Institute and in 1965 he graduated with the second M.Sc in mathematics from Faculty of Mechanics and Mathematics of Moscow State University. In 1968 he obtained his Ph.D. degree from Moscow Institute of Physics and Technology (MIPT).

He held a Professor position at MIPT and worked in the Institute of Control Sciences until 1990, when he joined the Institute for Information Transmission Problems as the head of the Stochastic Dynamic Systems Laboratory.

In 1993 emigrated to Israel and lived in Kfar Saba. In Israel he held a Professor position at the School of Electrical Engineering in Tel Aviv University, until his retirement in 2005.

Research

Liptser made several important contributions to the theory of martingales and to their applications in engineering and statistics. This includes his study of the conditionally Gaussian processes, which play an important role in the separation principle in stochastic control.

He coauthored a number of influential books. His monograph "Statistics of Random processes: General Theory and Applications", written together with Albert Shiryaev in 1974, has become internationally renowned reference textbook among scholars, working in stochastic analysis and related fields.

DBOMP. DBOMP (Database Organization and Maintenance Processor) was an early hierarchical database system from IBM for DOS.  DBOMP was introduced in the late 1960s as a successor to IBM's "Bill of Materials Processor" called BOMP, introduced in 1965 when DOS became available.

DBOMP stored records on disk and was generalized beyond bill of materials.  BOMP was named from manufacturing industry's bill of materials processing in USA, (usually known as parts list processing in the UK) and specifically aimed at that industry sector. The major files were actually called Part Number Master File and Work Centre File, and the linking files were called Product Structure File and Routing File. Shortly after introduction, however the software was already being used for other purposes. One user who bred prize pigs used it to trace the ancestry of his animals— like race horses, the ancestry of these pigs directly affected their considerable commercial value.  The possibilities were recognised with the announcement of DBOMP itself, where the basic file structures and inter-relationships remained the same, but the files were renamed to make them less manufacturing-specific.        

There is some disagreement as to whether DBOMP should be called a hierarchical or a network database.  This was a marketing competition between IBM and competitive offerings: network had become popular, and BOMP and DBOMP did have network characteristics, but these were limited.

The structure of DBOMP databases limited its use to CKD disk drives with no more than 511 cylinders.  It was a long time before this became a problem, but the more serious limitation was that each pointer address stored in one record to link it to another was a physical (Cylinder/Head/Record) address on the disk.  Moving a file from one pack to another required it to be placed in exactly the same physical position on the new pack.  Also, if the installation migrated to bigger disks, the whole database had to be unloaded into sequential files and reloaded through the software provided to fit the new pack dimensions,  More seriously, the programmer was responsible for managing the physical pointers in the header of each record, directly beside normal business data.  The IBM replacement for DBOMP was the DOS implementation of DL/I database, where the pointer information was carefully shielded from the program.  

The structure of DBOMP files heavily influenced later databases such as Cincom's Total.

Audio bus. In audio engineering, a bus (alternate spelling buss, plural busses) is a signal path that can be used to combine (sum) individual audio signal paths together. It is typically used to group several individual audio tracks which can be then manipulated, as a group, like another track. This can be achieved by routing the signal physically by way of switches or cable patches on a mixing console, or by manipulating software features on a digital audio workstation (DAW).

By using buses, an engineer may apply audio signal processing to entire groups of tracks. For example, lead vocals and backup vocals may be mixed and routed through a single compressor, creating a result unique from that reached by compressing each track individually, while reducing the overall amount of hardware or digital memory required for processing. A technique known as stem mixing and mastering relies on the use of busses to mix tracks down to stems for processing before mixing down to the stereo bus (also called "master channel" or "2-bus"). This usually reduces the amount of processing applied to the stereo bus and increases the control the engineer has over the dynamics and levels of the overall mix. Busses can also be helpful when working on complicated audio projects with many tracks, where an engineer may wish to apply changes to multiple tracks at once, such as all of the drum mics or all of the vocal mics.

Niobium disulfide. Niobium disulfide is the chemical compound with the formula NbS2. It is a black layered solid that can be exfoliated into ultrathin grayish sheets similar to other transition metal dichalcogenides. These layers exhibit superconductivity, where the transition temperature increases from ca. 2 to 6 K with the layer thickness increasing from 6 to 12 nm, and then saturates with thickness.

Boeing Cargo Air Vehicle. The Boeing Cargo Air Vehicle is an unmanned, autonomously flying, fully electric cargo air vehicle (CAV).  It was made possible by an investment of Boeing HorizonX Ventures.

Development
At the beginning it was remote control-operated. Later it flew autonomously. The first flight tests have been in 2017. The CAV is for research of autonomy technology for aerospace vehicles in the future. In Boeing's Ridley Park wind tunnel flight tests have been finished. It was flying indoor in 2018 before outdoor flights in 2019. With the Boeing CAV there are new possibilities for the transport of time-sensitive and high-value goods and to conduct autonomous missions in remote or dangerous environments. Its configuration evolved to six dual-rotor systems with 12 propellers and the first outdoor flights tests were done by May 2019, including forward flight transition.

By September 2020, Boeing was to close its Boeing NeXt division, in response to financial losses in the wake of the 737 MAX groundings and the impact of the COVID-19 pandemic on aviation.

Design
The CAV was designed and built by 50 engineers in less than three months.

Brady catamarans. Brady catamarans  are twin-hulled boats that are designed by Peter Brady  a well respected New Zealand  designer. Brady originally designed sailing cats, motorsailers and power cats, but for the last 20 years the firm (now called Pathfinder Powercats) has specialised in powered catamarans exclusively.

Brady catamarans are either constructed at Brady's boatyard in Brisbane Australia, or plans-built by third-party constructors for private owners. Brady catamarans tend to be built in small numbers or even as one-offs, so the firm has adopted "strip-plank" as the optimum construction method. Strip-build involves attaching strips of cedar onto formers, the strips themselves being glued edge-on with epoxy. The completed wooden monococque is then covered with fiberglass matting and epoxy resin. This method is very suitable for low-volume construction, avoiding the need to build a female mould; it is simpler and cheaper to manufacture a plywood jig that may be discarded afterwards.

Brady catamaran models
Brady catamaran models include:
 Brady 45 - sailing yacht with twin 40 hp Yanmar auxiliary engines.
 Brady 52 "Passagemaker" - a motorsailer with a modest-area staysail schooner rig and twin Perkins 95 hp main engines.
 Brady 57 "Pathfinder pilothouse 17.4" - a luxury 57' cruising motoryacht.
 Brady Pathfinder M Series - a range of displaning power catamarans between 41 and 49 ft.
 Brady Powercats - various models for leisure, fishing, and business use.

Helicopter Brigade of Russian Airborne Troops. The helicopter brigade of Russian Airborne Forces is a plan of the Ministry of Defense of Russia to create a brigade of army aviation as part of the Airborne Forces.

Story 
In December 2012, the commander of the airborne troops, Colonel-General Vladimir Shamanov, offered to include army aviation in the composition of the brigade of the Airborne Forces as an experiment.

“We want to propose to include a helicopter regiment in the 31st separate airborne assault brigade: 40 Mi-8 helicopters and 20 Mi-24 helicopters. I emphasize that they are part of the brigade ... It’s difficult to meet us or the General Staff. Over the past 2 years, almost all of our applications for the allocation of army aviation have been met, "said Shamanov at a press conference in Moscow.

Cause 

Currently, army aviation brigades are organizationally part of the Aerospace Forces. At the same time, they are operatively subordinated to the command of military districts.

In this regard, the commander of the Airborne Forces in order to plan the transfer of units, you must go through a lot of approvals at the level of higher headquarters. Therefore, precious time is lost. In addition, a large number of participants in such negotiations may lead to information leaks. This negates the key factor of the Airborne Forces - surprise.

Another reason: in the conditions of powerful air defense, the most effective is the transfer of troops by helicopter, which is almost imperceptible at ultra-low altitudes. In addition, a helicopter for paratroopers is not only a means of delivery, but also fire support.

That is why it was decided to form its own aircraft in the Airborne Forces - airborne units will be able to use their helicopters without unnecessary delay.

Formation 

The Ministry of Defense of Russia noted that the proposal to form one air force brigade in the Airborne Forces as a whole was approved. A new brigade is planned to be formed in the next 2-3 years.

For the brigade it is necessary to order new helicopters. According to Izvestia sources, the helicopter brigade will report directly to the commander of the Airborne Forces.

The composition of the brigade 

The brigade will consist of 4 helicopter squadrons. The total number is 48–50 helicopters.

One squadron will be equipped with Mi-35M “Super Crocodile” drums - this model, unlike the main attack helicopters Mi-28N and Ka-52, can carry up to seven people of the assault force. Two squadrons will receive in service the transport and combat Mi-8AMTSH-V. Fourth - super heavy Mi-26T2 helicopters.

Dislocation 

The brigade will be based either in Ryazan, Voronezh or Orenburg.

Hambantota Refinery. The Hambantota Refinery (also called Greenfield Oil Refinery) is an oil refinery to be developed in Mirijjawila, Hambantota, in the Southern Province of Sri Lanka. The  refinery will be built and owned by Singapore's  (70%) and Oman's Ministry of Oil and Gas (30%). Silver Park International is an investment vehicle owned by India's Accord Group. It will have a refining capacity of  per stream day, ten times the capacity of the Sapugaskanda Refinery, the country's only other refinery which was built in 1969 by Iran.

At a cost of  , the refinery development is the single largest foreign direct investment in Sri Lanka's history. Construction of the first phase will commence on 24 March 2019 at a groundbreaking ceremony in the Mirijjawila Export Processing Zone, with Prime Minister Ranil Wickremesinghe attending as chief guest, with the project slated for completion in 44 months.

Almost the entire output from the refinery will be exported, generating an estimated annual revenue of  . However, CEYPETCO and Lanka IOC could bid for refined petroleum products at competitive prices to supply to local consumers.

Storage and export 
Under construction first phase,   will be assigned to construct the oil terminal, pipeline, and other infrastructure. The oil terminal will be able to store  of crude oil, and around  of refined petroleum products.

Exports from the refinery will be channelled through the now Chinese-owned Hambantota Port, which has been mostly idle for nearly a decade since being built. The port, initially state-owned, has been leased to China in 2017 for 99 years, after Sri Lanka was unable to service a loan from Beijing.

History 
 Before 2017, a  per stream day refinery was agreed to be built at Trincomalee by Indian Oil Corporation, although no progress has been made since.
 In September 2017, Sri Lanka engaged in talks with two Chinese companies for a $3 billion refinery in Hambantota.
 During President Maithripala Sirisena's official visit to Tehran, cabinet spokesman Rajitha Senaratne stated that Iran has agreed to build a refinery and will send a team for assessments.
 19 March 2019, Sri Lanka confirms  refinery with Singapore's  and Oman's Ministry of Oil and Gas.
 21 March 2019, Oman denies ever being aware of the  refinery deal. Director General of Sri Lanka's state-run Board of Investment, Champika Malalgoda, then stated that the project would still go ahead, although without clarification on this situation or how the missing investment would be covered.
