SAND CDBMS. SAND Nucleus CDBMS is a column-oriented DBMS software system optimized for business intelligence applications, delivering the data warehousing component, developed by SAND Technology Inc.

Company history
SAND Technology was founded in 1983.

SAND CDBMS traces its roots to developments by Nucleus International Corporation research and eventual patent issued to, among others, Edward L. Glaser on “Bit string compressor with boolean operation processing capability.”

Originally encoded on firmware, the application is now completely software based.

SAND Technology is now a division of N. Harris Computer Corporation.

Description
A fully tokenized, bit array encoded and compressed database, data storage is column-oriented using domains across schemas/tables rather than as rows of data within tables.  This results in an optimized platform for data analytics and data mining, although not suitable for transaction processing.

This architecture exhibits the following characteristics:
All columns act as if they are indexed
Actual data values are stored only once and referenced by their token
Columns use lossless data compression when stored
Only columns requested in a query are accessed from the database
Queries are done directly on the compressed columns and only the result set is decompressed.

Platform agnostic, SAND CDBMS runs on 64 bit Windows or the following 64 bit Linux/Unix environments: HP-UX, IBM-AIX, Red Hat Linux, SuSE Linux and Sun Solaris.

Database Administration

SAND/DNA Analytics is managed via ANSI standard SQL and DML commands.

Database space allocation and core management are done by the database engine.  This means typical database administration is focused on data modeling, data content, managing the data life cycle and managing the user profiles and access permissions.

Data loading is straight forward and only requires pointing to the source and destination in load scripts.  There are multiple data manipulation functions and commands available, but all internal structure optimizations are automatically managed by the database engine.

While data load performance can be slower than row based databases, it is mitigated by not having to build any indexes or run post-load administration routines once complete.  Parallel load processing or segmented pre-load processing can also be used to improve load performance.

A core feature of SAND CDBMS is its support of “virtual” mounting of a database.  This provides an isolated environment for developing and testing changes to a database, where upon dismounting, the entire environment is removed.

Baco Liner. BaCo Liner an abbreviation for 'Ba'rge - 'Co'ntainer - Carrier, was a shipping service between Europe and Africa owned by Seerederei Bacoliner GmbH of Duisburg, Germany. It used a fleet of specialized barge carrying LASH vessels which have a very unusual design: they carry both conventional shipping containers, and barges that are loaded through twin doors in the bow, a kind of 'float in-float out' arrangement.

This system of barges inside a larger ship allowed cargo to be discharged while at anchor mid-stream in African ports, avoiding port delays.  The barges could be loaded up to 800 tonnes each, 12 could be loaded per ship. Container capacity was 500-650 TEU.

Each vessel was approx. 205 m long, 28.5 m beam, operating on a loaded draught of 6.65 m. Gross tonnage 22345 tonnes, deadweight 21800 tonnes including 12 barges with 800 tonnes each.  Service speed was 15 knots.

In 2007, 24 Filipino crew of a Baco Liner vessel were kidnapped by pirates in Chanomi Creek, Nigeria.

Fleet and fate 
The fleet comprised the three barge carriers: BACO-LINER 1, BACO-LINER 2 and BACO-LINER 3, all completed between 1979 and 1984 by Thyssen Nordseewerke GmbH at Emden.  They sailed under the Liberian flag, serving ports between Nouadhibou, Mauritania, and Port Harcourt, Nigeria.

BACO-LINER 3 was scrapped in Alang Beach, India, in July 2012.  BACO-LINER 2 followed there in June 2013 and BACO-LINER 1 in August 2013. Vessel tracking services now list all three Baco-liners as scrapped.

Structural acoustics. Structural acoustics is the study of the mechanical waves in structures and how they interact with and radiate into adjacent media.  The field of structural acoustics is often referred to as vibroacoustics in Europe and Asia.  People that work in the field of structural acoustics are known as structural acousticians.  The field of structural acoustics can be closely related to a number of other fields of acoustics including noise, transduction, underwater acoustics, and physical acoustics.

Vibrations in structures

Compressional and shear waves (isotropic, homogeneous material)
Compressional waves (often referred to as longitudinal waves) expand and contract in the same direction (or opposite) as the wave motion. The wave equation dictates the motion of the wave in the x direction.

where  is the displacement and  is the longitudinal wave speed.  This has the same form as the acoustic wave equation in one-dimension.   is determined by properties (bulk modulus  and density ) of the structure according to

When two dimensions of the structure are small with respect to wavelength (commonly called a beam), the wave speed is dictated by Youngs modulus  instead of the  and are consequently slower than in infinite media. 

Shear waves occur due to the shear stiffness and follows a similar equation, but with the displacement occurring in the transverse direction, perpendicular to the wave motion.

The shear wave speed is governed by the shear modulus  which is less than  and , making shear waves slower than longitudinal waves.

Bending waves in beams and plates

Most sound radiation is caused by bending (or flexural) waves, that deform the structure transversely as they propagate.  Bending waves are more complicated than compressional or shear waves and depend on material properties as well as geometric properties.  They are also dispersive since different frequencies travel at different speeds.

Modeling vibrations
Finite element analysis can be used to predict the vibration of complex structures.  A finite element computer program will assemble the mass, stiffness, and damping matrices based on the element geometries and material properties, and solve for the vibration response based on the loads applied.

Sound-structure interaction

Fluid-structure Interaction

When a vibrating structure is in contact with a fluid, the normal particle velocities at the interface must be conserved (i.e. be equivalent).  This causes some of the energy from the structure to escape into the fluid, some of which radiates away as sound, some of which stays near the structure and does not radiate away. For most engineering applications, the numerical simulation of fluid-structure interactions involved in vibro-acoustics may be achieved by coupling the Finite element method and the Boundary element method.

NBI Knowledgebase. NBI  is short for the Nanomaterial-Biological Interactions Knowledgebase at Oregon State University, a repository for annotated data on nanomaterials characterization (purity, size, shape, charge, composition, functionalization, agglomeration state), synthesis methods, and nanomaterial-biological interactions (beneficial, benign or deleterious) defined at multiple levels of biological organization (molecular, cellular, organismal). Computational and data mining tools are being developed and incorporated into the NBI to provide a logical framework for species, route, dose, and scenario extrapolations and to identify key data required to predict the biological interactions of nanomaterials.

Information currently being gained in the emerging field of nanotechnology is extremely diverse, including a multitude of widely varying nanomaterials that are being or will be tested in a broad array of animal systems and in vitro assays. Knowledge of nanomaterial-biological interactions will likely require inclusion and consideration of the entire body of data produced from global research efforts, which will allow the definition of nanomaterial structure-activity relationships. Such mathematical representations can be used to predict nanomaterial properties in the absence of empirical data.

Shaft (civil engineering). In civil engineering a shaft is an underground vertical or inclined passageway. Shafts are often entered through a manhole and closed by a manhole cover. They are constructed for a number of reasons including:

 For the construction of a tunnel
 For ventilation of a tunnel or underground structure, aka ventilation shaft
 As a drop shaft for a sewerage or water tunnel
 For access to a tunnel or underground structure, also as an escape route

Construction 

There are a number of methods for the construction of shafts, the most significant being:

 The use of sheet piles, diaphragm walls or bored piles to construct a square or rectangular braced shaft
 The use of segmental lining installed by underpinning or caisson sunk to form a circular shaft
 Incremental excavation with a shotcrete circular or elliptical lining
 Incremental excavation supported by shotcrete, rock bolts, cable anchors and steel sets or ribs

Shafts can be sunk either dry or for methods such as the caisson method they can be sunk wet. Sinking a dry shaft means that any water that flows into the excavation is pumped out to leave no significant standing or flowing water in the base of the shaft. When wet sinking a shaft the shaft is allowed to flood and the muck is excavated out of the base of the shaft underwater using a grab on the end of a crane or similar excavation method. Because the shaft is flooded, the lining can not be constructed at the excavation level of the shaft so this method only suits methods where the lining is installed before shaft sinking (such as the use of sheet piles) or where the lining is sunk down with the shaft such as the caisson method.

Arab Mashreq International Railway. The Arab Mashreq International Railway is a proposed railway network in the Mashriq, which is located in Western Asia and eastern North Africa in the eastern part of the Arab world. The planned network has north–south and east–west axes, and 16 different routes covering 19500 route-km. The plan is ambitious; 60% of the routes have not yet been built, and parts of existing railway infrastructure are weak or have gauge differences; some states may be unable to make large investments in infrastructure. Like the European Trans-European Transport Network, the Agreement specifies a family of high-priority international routes, rather than setting service details or awarding contracts to operators.

International agreement
The Agreement on International Railways in the Arab Mashreq was adopted on 17 April 2003. It entered into force on 23 May 2005 after it had been ratified by Egypt, Jordan, Lebanon and Syria. As of July 2016, it has been ratified by 12 states: Bahrain, Egypt, Iraq, Jordan, Kuwait, Lebanon, Saudi Arabia, the State of Palestine, Sudan, Syria, United Arab Emirates, and Yemen.

RT middleware. RT-middleware (Robotics Technology Middleware) is a common computing platform technical standard for robots based on distributed object technology. RT-middleware supports the construction of various networked robotic systems by integrating various network-enabled robotic elements named RT-Components, which specification standard is discussed and defined by the Object Management Group (OMG).

Properties 
In the RT-middleware, robotics elements, such as actuators, are regarded as RT-components, and the whole robotic system is constructed by connecting such components. This distributed architecture helps developers reuse the robotic elements and boosts the reliability of a system.

Each RT-component has a port as an endpoint for communicating to other RT-components. Every port has its type and the ports which have the same type can be connected each other.

RT-components also have state, so they behave as finite-state machines. The states they can have are: CREATED, INACTIVE, ACTIVE, and ERROR. States and behaviors are controlled by the execution-context. If component behavior must be changed, the execution-context can be replaced at runtime.

Implementations 
RT-middleware is only a standard of the Robotics platform software. Implementations include:

 OpenRTM-aist is based on the Common Object Request Broker Architecture (CORBA) platform developed by National Institute of Advanced Industrial Science and Technology. Using CORBA properties, OpenRTM-aist is available for environments with multiple platforms and programming languages.
 OpenRTM.NET is for the .NET Framework.
 RTM on Android is being implemented on Android (operating system).
 RTC Lite is a future modified RT-middleware for embedded or small-resource systems.
 RTM Safety to pass the IEC 61508 standard.

Inerter (mechanical networks). In the study of mechanical networks in control theory, an inerter is a two-terminal device in which the forces applied at the terminals are equal, opposite, and proportional to relative acceleration between the nodes. Under the name of J-damper the concept has been used in Formula 1 racing car suspension systems.

It can be constructed with a flywheel mounted on a rack and pinion. It has a similar effect to increasing the inertia of the sprung object.

Discovery
Malcolm C. Smith, a control engineering professor at the University of Cambridge, first introduced inerters in a 2002 paper. Smith extended the analogy between electrical and mechanical networks (the mobility analogy). He observed that the analogy was incomplete, since it was missing a mechanical device playing the same role as an electrical capacitor. The analogy makes mass the analogy of capacitance, but the capacitor representing a mass always has one terminal connected to ground potential. In a real electrical network, capacitors can be connected between any two arbitrary potentials, they are not limited to ground.  Noticing this, Smith set about finding a mechanical device that was a true analog of a capacitor. He found that he could construct such a device using gears and flywheels, one of several possible methods.

The constitutive equation is,
 ,
where the constant b is the inertance and has units of mass.

Construction
A linear inerter can be constructed by meshing a flywheel with a rack gear. The pivot of the flywheel forms one terminal of the device, and the rack gear forms the other.

A rotational inerter can be constructed by meshing a flywheel with the ring gear of a differential. The side gears of the differential form the two terminals.

Applications
Shortly after its discovery, the inerter principle was used under the code name of J-damper in the suspension systems of Formula 1 racing cars. When tuned to the natural oscillation frequencies of the tires, the inerter reduced the mechanical load on the suspension. McLaren Mercedes began using a J-damper in early 2005, and Renault shortly thereafter. J-dampers were at the center of the 2007 Formula One espionage controversy which arose when Phil Mackereth left McLaren for Renault.

Researchers are developing new vibration-control devices based on inerters to build high-rise skyscrapers which can withstand high winds.
