1) Announcing Availability of SANKHYA Varadhi - Version 1.1, Beta-4 Release.

(Attached: SANKHYA Varadhi - Version 1.1, Beta-4 Release Announcement)

2) Using Varadhi for Building Energy Simulation, Automation and Analysis:

SANKHYA Varadhi (http://www.sankhya.com/info/varadhi.html) is an Object
Middleware Platform that can be used for creating a distributed system 
that Simulates and/or Manages intelligent buildings without the need for 
centralized control.

 a) A building automation usage scenario is provided at the following location:


 b) Here is an example that demonstrates the use of CORBA in Building 
    Energy Simulation:

Using Varadhi, different entitites that are part of a Building, which 
have to be simulated/analyzed can be treated as objects. For example,
it should be possible to declare a CORBA IDL interface as shown below 
(An example only - a real interface (or set of interfaces) are better 
designed and standardized by a group of domain experts).

 interface window {

  attribute long external_temparature;
  attribute long internal_temparature;

  // Low Tech: Adjust Ventilator; Hi-Tech: Don't know :-)
  void set_conductivity(in long c);

  attribute long internal_luminance;
  attribute long external_luminance;

  // Low Tech: operate blinds. Hi-Tech: Use a polaraid film
  void set_translucence(in long t);



Consider an 'Intelligent Window' that can be configured for optimal 
energy control. Now, a simulation system can use a 'Simulated' Window 
Object that implements the above interface. A 'real' system would use 
an actual intelligent window. Either case, the other objects in the 
system need not know if something is being 'simulated' or if it is real !

Basically, this will allow simulation of parts of a system working together 
with other 'real' parts of the system. As well as provide for a standard 
framework for fitting together 'simulation components' that can be designed 
and implemented by different groups and companies ! These can run on different 
computers, be implemented in different languages and SANKHYA Varadhi 
(possibly along with other ORBs) will take care of such language and 
location details in a standards compliant manner.

Announcing Availability of SANKHYA Varadhi - Version 1.1, Beta-4 Release.

Chennai, India; November 21, 2001

Sankhya Technologies today announced the availability of a free evaluation 
version (Beta4) of its Object Middleware Product -- SANKHYA Varadhi.

SANKHYA Varadhi is an Object Request Broker compliant with OMG's 
CORBA 2.2 (Minimum CORBA). Varadhi provides embedded system developers
a standards-based framework for building and deploying distributed systems.

SANKHYA Varadhi Beta-4 is available for download for evaluation purposes.
A 30-Day free evaluation license including free support during the evaluation
period is available. Visit the following links for additional details:


This release of SANKHYA Varadhi improves on the earlier releases by adding
the following features:

   -> Cross Platform Development Support for PowerPC, MIPS and x86

   -> Enhanced Transport Layer Abstraction including connection caching and
      support for porting to new platforms.

   -> Reduced Memory Footprint. A simple and complete Varadhi client/server for 
      the x86 target takes up just about 100KB of space (code size + data size).

   -> Enhanced OS Layer Abstraction with support for porting to new platforms.

   -> Includes Varadhi Names Beta-2 and an enhanced nsman - Naming Service 
      Manager tool.

   -> Greatly enhanced IDL compiler.
