1. The Helium Balloon based Stationary Surveillance Platform is a tethered aerostat. A tethered aerostat is an aerial platform that has better performance than small helicopters or airplanes in aerial surveillance applications that require stationary, noiseless platform. The platform is inherently stable which lead to simpler control mechanisms with the advantage that the platform is not destroyed or mangled in the event of a system failure.

2. The platform can provide continuous ground surveillance for an extensive period of time (depending on the duration of battery power). A daylight operated wireless IP (Internet Protocol) camera with PTZ (Pan Tilt Zoom) capability is mounted on the underside of the aerostat. The real time video acquired is transmitted to the receiving station using a 2.54GHz (Wi Fi band) video link. The aerostat can also be fitted with a low-eight infrared camera for night time observations.

3. To provide stability in air an ellipsoid shaped PVC balloon inflated with helium is used as the aerostat. The ellipsoid shape ensures that the platform is kept stable under low/moderate winds due to its aerodynamic features. The aerostat is tethered to the ground by two nylon cords operated by winches. The prototype was completed and demonstrated in December 2010.

Abstract

During the data collection process of the Center for Research and Development (CRD) and Center for Dengue Research (CDR) it was revealed that the spatial data collection and on-time data visualization have been major challenges in Dengue control programs. Therefore an attempt has been made to introduce a GIS and Mobile Communication based Geo-tagged Dengue Incidents Reporting System by installing a specially developed Mobile App into the Android Mobile Phones of the front line field health officers (PHIs), enabling them to enter basic data on the patients from the field on a real time basis. Accordingly, the data and information of the cases are geo-tagged to the user's location and shown on Google Maps, ArcGIS Server or ArcGIS Desktop. This system will vastly reduce the time lag between collecting and reporting data and preventive action taken by the authorities. The app is quick and easy to use for health workers who are constantly on the move and performing multiple duties; it is simply a click of a button, rather than pages of paper work.

Health Mapping

In 1854, an English physician, John Snow, provided the classic example of how mapping can be used in epidemiological research. He identified the water source responsible for an outbreak of cholera in London by mapping the locations of those afflicted.

GIS has continued to be used in public health for epidemiological studies. By tracking the sources of diseases and the movements of infections, agencies can respond more effectively to outbreaks of disease by identifying at-risk populations and targeting intervention. Geographic Information System (GIS) is a Special kind of "Information System" that is used to input, store, retrieve, manipulate, analyze and output geographically referenced data or geospatial data

The Problem

As a part of the research carry out by the Center for Dengue Research (CDR) it was decided to analyze the Spatial and Temporal Clustering of Dengue within the Spatial Study Region (Colombo District). Accordingly, data on the reported Dengue cases from 2009 to 2012 by PHI Areas were collected from MOH Offices. The most challenging task was identifying the locations of Dengue patients using mail addresses recorded the by Public Health Inspectors (PHIs).

The method followed: Obtained the assistance of Postman to locate the address on Google Earth.

Concerns

Identifying Postal Address on the Map is Very Difficult There will be many human errors If we could map the locations of dengue epidemic real time that would be very helpful to health authorities. The method we used to identify Dengue Patients locations may not be sustainable in long term Communication difficulties during data collection and sharing

System Solution

- Android based Application
- Data store in phone database and send to server
- No GSM coverage area Data will store in Phone database and sending first time GSM signal received
- Software can be download from Website
- Register with IMEI number (Security)
- Automatically pick the current location
- Drop down menus radiuses human errors

Conclusion
The real-time information system introduced by this research team can boost the authoritie’s efforts to keep a constant eye on the spread of dengue and, more importantly, help in using resources more accurately and in a more targeted manner. This new capability represents a significant shift in how the spread of dengue and other infectious diseases can and will be monitored in the future.

1. The project will be carried out as a pilot project to digitize the Gampaha and Northern district utility and infrastructure maps along with a well defined citizen database. This will enable the country or the administrators to make decisions in efficient and effective manner rather than ad-hoc collection of information. This also saves Millions of Rupees from government itself by sharing information among public and private institutions that will require these types of utility and infrastructure maps.
GISDA - Colombo Infrastructure Mapping and Modelling (CIMM)

Ballistic rubber is used to prevent bullets ricochet in indoor firing ranges. These products are highly expensive. The CDRD introduced the first locally developed ballistic rubber of Sri Lanka with a local company (Microcells Pvt Ltd) proved to be sufficient to contain a directly fired high-velocity shot from a close range, such as 6 inches. With the improved elasticity and strength to absorb a higher number of shots using a synthetic and natural rubber mixture, the rubber product finally proved to be very economical during the final test firing while assuring maximum safety to the firers.

The first sets of ballistic rubber were installed at Commando Regiment Ganemulla (MILO Firing Range) and in the Underground firing range Vavunia.

This 40 feet indoor live firring range is designed for target practice purposes. The range is a pistol rated with a single firing lane. The basic concrete infrastructure had been completed by Special Forces a few years ago and was being abandoned. On the request of the Commander of the Army, CDRD undertook the task of completing the range. The project was handed over to Special Force in the year 2019.

The project involved designing of assault shields to protect from direct small arms fire. This was completed as a special request by the Special Forces during the post- Easter Attacks. The project was handed over to Special Force in the year 2019.

Indexed as Ce-FRAD-2019, the pistol rated mobile live firing range is installed inside a 40 ft long shipping container and fully ballistic, protected with newly-developed ballistic rubber, that too has been manufactured and newly-developed by the same researcher.

CDRD successfully managed to develop the first low-cost prototype for Rs 4.6 million, with all facilities, available in such units produced overseas. Ce-FRAD 2019 is considered as a significant outcome for the Sri Lankan military as it also built as a module to introduce the indoor live firing range concept for the Sri Lankan Military.

Completing another successful research project, the Defence Ministry’s Centre for Research and Development (CRD) introduced a new method for ‘Blue Gun’ production to Sri Lankan Tri-Services. This initiative minimises the damages caused to real weapons of high value while increasing their lifetime and ensuring the safety of trainees. CRD has fabricated replicas of Browning HP Pistol and an HK Gun for the purpose. Blue Guns are heavily used by the world’s professional militaries for weapon handling and training sessions without live rounds.

CDRD Introduced the first Digital Close Quarter Combat Theatre (MILO Range) of Sri Lanka which could facilitate live-firing training sessions of Commandos and Special Forces.

This exceptionally-designed low-cost digital training theatre, equipped with live firing facility was specially designed for Commandos and Special Forces and operates on a digital platform similar to the MILO ranges in the US. The new system uses life size real videos running on surrounding digital screens to provide trainees real time feelings, combined with stress and ambiguity, instead of 3D objects, generally projected in traditional simulators.

Live firing can be used in this way to train special operation soldiers and evaluate their performance under stress and different training scenarios, like shoot or no shoot, skill-building, decision-making, etc. The system also includes an instant feedback system which playbacks every episode for the trainees and instructors to see their performances in return for self-evaluation.

“AK Bullet Trajectory Plotter”, use the dimensions of AK bullet holes produced in soft-skinned vehicles to estimate the trajectories of the fired bullets and proved to be effectively employed to identify the possible shooter direction, when it is unknown. The research outcome which saw the light after a series of scientific experiments was introduced as a reliable and novel method for the existing bullet trajectory reconstruction methods practised in the world. Due to the international significance of the findings to the field of Forensic Ballistics, the research outcomes have been published in the famed peer-reviewed journals in the world “Journal of Forensic Sciences” and “ Forensic Science International” published by the American Academy of Forensic Sciences, USA and Elsevier Publishers.

The new method was introduced and demonstrated for the Police and Military Police units of the Tri-services, at the Army Field Firing Range, PANALUWA.

Customized 2 x ballistic blankets were developed for the use of the Commander of the Army. This was a special request from the Sri Lanka Army. Ballistic blankets are used to protect VIPs travelling in soft-skinned vehicles. The project was handed over to Army Commander's Security Unit in 2019.
