Unmanned Aerial Vehicles (UAVs) are aircrafts that fly without any humans being onboard. They are either remotely piloted, or piloted by an onboard computer. This kind of aircrafts can be used in different military missions such as surveillance, reconnaissance, battle damage assessment, communications relay, minesweeping, hazardous substances detection and radar jamming. However they can be used in other than military missions like detection of hazardous objects on train rails and investigation of infected areas. Aircrafts that are able of hovering and vertical flying can also be used for indoor missions like counter terrorist operations.

Video Encryption and Decryption with Authentication using Artificial Neural N...IOSR Journals
Abstract :Multimedia data security is becoming important with the continuous increase of digital
communications on internet. With the rapid development of various multimedia technologies, more and more
multimedia data are generated and transmitted in the medical, commercial, and military fields, which may
include some sensitive information which should not be accessed by or can only be partially exposed to the
general users. . The encryption algorithms developed to secure text data are not suitable for multimedia
application because of the large data size and real time constraint. Therefore, there is a great demand for
secured data storage and transmission techniques. Information security has traditionally been ensured with
data encryption and authentication techniques. The secrecy of communication is maintained by secret key
exchange. In effect the strength of the algorithm depends solely on the length of the key. The presented work
aims at secure video transmission using randomness in encryption algorithm, thereby creating more confusion
to obtain the original data. The security of the original cipher has been enhanced by addition of impurities to
misguide the cryptanalyst. Since the encryption process is one way function, the artificial neural networks are
best suited for this purpose as they possess features like high security, no distortion and its ability to perform for
non linear input-output characteristics, In the presented work the need for key exchange is also eliminated,
which is otherwise a perquisite for most of the algorithms used today. The proposed work finds its application in
medical imaging systems, military image database communication and confidential video conferencing, and
similar such application. The results are obtained through the use of MATLAB 7.14.0

Modeling and qualitative analysis of malaria epidemiologyIOSR Journals
We develop and analyze a mathematical model on malaria dynamics using ordinary differential equations, in order to investigate the effect of certain parameters on the transmission and spread of the disease. We introduce dimensionless variables for time, fraction of infected human and fraction of infected mosquito and solve the resulting system of ordinary differential equations numerically. Equilibrium points are established and stability criteria analyzed. The results reveal that the parameters play a crucial role in the interaction between human and infected mosquito.
A study of serum Cadmium and lead in Iraqi postmenopausal women with osteopor...IOSR Journals
Postmenopausal status is an independent risk factor for osteoporosis. Several studies have reported that heavy metals, including lead, mercury, cadmium, and arsenic, have harmful effects on bone. The aim of this study was to evaluate the effect of heavy metals, including Cadmium and Lead on osteoporosis in postmenopausal Iraqi women. This prospective study included a total of 70 postmenopausal women divided as 40patients with osteoporosis compared to 30 apparently healthy women as controls during 2011. Serum levels of Cadmium and Lead were measured using atomic absorption while serum Calcium, Phosphorus and Alkaline phosphatase were measured by spectrophotometry.The results showed that there was no significant difference between patients and controls regarding age, Body Mass Index, Calcium, Phosphorous, and Alkaline phosphatase. Serum levels of Cadmium and Lead were higher in patients compared to controls, p < 0.001 and p< 0.01 respectively. It is concluded that increased serum levels of cadmium and lead maybe associated with higher risk of osteoporosis in postmenopausal women.
Unification Scheme in Double Radio Sources: Bend Angle versus Arm Length Rati...IOSR Journals
From radio source unification scheme, asymmetries are more pronounced in quasars than in radio galaxies. Using a sample of 625 double radio sources (316 radio galaxies and 309 quasars), we investigated the variations between bend angle, arm-length ratio and redshift. We find no significant correlation (0.045) between bend angle and redshift for the entire sample and at low z for radio galaxies while a weak correlation (0.121) between bend angle and redshift for quasars for the entire sampleis observed. A weak correlation (radio galaxies, r = 0.173 and quasars, r = 0.102) between the bend angle and arm-length ratio for the double radio sources used in this study is observed. Kharbet al. (2008) in their study of powerful classical double radio galaxies noted that this correlation could suggest that the environmental asymmetries that give rise to the arm-length ratio could be contributory to the misalignment angles in these sources. Quasars appear much more bent and misaligned. This is consistent with quasars being radio galaxies viewed at small angles.

The present study is concerned with the production of amylase by Bacillus species strain. In this
study 12 bacterial strains were isolated and screened for their α-amylase activity. These strains were
maintained on nutrient agar medium. Fermentation for the production of amylase was carried out in the enzyme
production medium (EPM). All the 12 strains were tested for amylase production. On the basis of maximum
amylase activity strain no.1 was selected for further studies. Different starch concentrations, 0.75,1.00,1.25%,
pH labels 6.5,7.0,7.5,8.0, aeration (RPM), 100,120,140, temperatures 250C,280C,370C, and 400C and inoculums

Technical Development of Design & Fabrication of an Unmanned Aerial VehicleIOSR Journals
: UAV (Unmanned Aerial Vehicle) is an air vehicle which is largely used for surveillance, monitoring,
reconnaissance, data relay, and data collection or to enter the area which is not safe for human i.e. flood
affected or virus affected area. This paper represents the unique design of such an UAV which designed at
MILITARY INSTITUTE OF SCIENCE & TECHNOLOGY to participate in an international competition SAE
Aero Design West-2013. As per competition requirement empty weight of the UAV must be less than 2 lb and
must fly with payload as heavy as possible for good scoring. Initially, the model of the UAV was tested in wind
tunnel and the test data showed that the model aircraft performance was capable enough for flying and covering
an area specified in the competition. Subsequently, an actual aircraft was fabricated of that model and flight
tested which proved the match with theoretical, statistical and experimental data that was obtained from wind
tunnel test, wing tip test, tensile test of manufacturing material and CFD (Computational Fluid Dynamics) flow
simulation over the aerofoil.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Abstract: An UAV (Unmanned Aerial Vehicle), or the drones, or the RC aircrafts are now a days in trends with
the hobbyists, armed forces or the kids for playful purposes. But if we see look around us, we will find that these
drones can help us in day to day life in saving some life which are in danger. Drones are prepared on the basis
of some particular application like aerial photography etc. But we the upcoming engineers should hold our
responsibilities and prepare something useful for the man on the front that could be a great serving for the
nation and as well as for them who really need this equipment for safeguarding our motherland.
Keywords: UAV (Unmanned Aerial Vehicle), Drones, RC (Radio Control), Ariel Photography, Hobbyists.
I. Introduction
The auto pilot controlled flying wing UAV is designed for the quick reaction armed forces. For the
surveying of areas affected by natural disasters like earthquakes, tsunamis, floods etc. and it can also be used for
aerial photography of agricultural lands and in any type of terrorism active areas. It will become more helpful to
our armed forces that can operate this vehicle in enemy territory without leaving any heat signature in any kind
radar due to its low heat signature design. It is having very high speed of maneuver and more than usual time of
flight than any other RC controlled UAV that makes this design more accurate for armed forces QRF division.
QRF divisions can use this UAV with an ease. It doesn’t require any bingo fields (Places to land), and can be
hand tossed from any moving vehicles, its body is fabricated in such a way that it cannot break during minor
crashes. Moreover the auto pilot enables the controller to recover the vehicle easily & where ever he/she wants.

II. Parts of Flying Wing
2.1 Fuselage
It’s the central part of the flying wing where all the electronic parts are positioned with respect of the
center of gravity of the entire aircraft. Fuselage serves a very crucial part in the flying wing; it not only holds the
electronic parts but also position the wings of the aircraft through carbon fiber rods. In this design no can find or
identify the fuselage as it is completely hidden from the outer environment. The body of aircraft is completely
fabricated in two parts which is its wings and fuselage as a combined additive.

2.2 Wings
Wings are the most crucial part of the flying wing drone. Wings and body of flying are the same and
can’t be distinguished. In flying wing drone two same size wings are attached together to form the fuselage &
body of the drone. Wings play a key role in lift. Wings generate the lift required to keep drones in air. Lift
occurs as the plane is pushed through the air. The top part of the wing is curved while the bottom is straight.

Which cause the air on top to move faster, the faster moving air on top of the wing creates a low pressure that
lifts while the higher pressure on the bottom of the wing.

2.3 Aero Foil
An aero foil is the term used to describe the cross-sectional shape of an object that, when moved
through a fluid such as air, creates an aerodynamic force. Aero foils are employed on aircraft as wings to
produce lift or as propeller blades to produce thrust. Both these forces are producing perpendicular to the air
flow.

Figure 4 (Foil Analysis Calculating Velocity Ratio On Java Foil)
In java foil, the foils created on the Auto CAD can be imported directly for analysis purpose. The
analysis report shows the pressure coefficient and the velocity ratio of the air to the aircraft. This help in easy
analysis of the wing that it can sustain into the flight in the air or not. Java foil analysis also shows up the
velocity gradient of the aircraft.

III. Automation Through Laptop Interface
Automation is enabled in the flying wing with help of a hardware Ardu Pilot and software interface
called the Mission Planner. Mission planner helps us to establish control on the plane. The Mission Planner,
created by Michael Oborne, does a lot more than its name. Here are some of the features:
1) Point-and-click waypoint entry, using Google Maps/Bing/Open street maps/Custom WMS.
2) Select mission commands from drop-down menus.
3) Download mission log files and analyze them.
4) Configure APM settings for your airframe.
5) Interface with a PC flight simulator to create a full hardware-in-the-loop UAV simulator.
6) See the output from APM’s serial terminal.

IV. FPV Introduction (First Person View)
In FPV (first person view) system, a wireless camera is attached with the transmitter working on 2.4
GHZ frequency that can transmit data up to a range of <250 meters. This system is mounted on the flying wing
on the front of the nose or on the bottom CG of the UAV. This unit has a sub part called as the receiver of the
system. The receiver is used to receive the signals transmitted from the transmitter of the camera, and then it
converts the signals & flashes them on the portable monitor or screen. This secondary system is also called as
the ground station or the ground unit. When the pilot is flying the UAV and wants to see what the drone is
seeing and where it is heading after getting away from the line of sight of the pilot. This system is useful when
you are far and want to trace the target site. Or get visual from enemy territory. It’s easy to use and very handy.

V. Conclusion
Conclusion is straight and clear that we require this kind of low profile drones equipped with FPV units
combined through Laptop synchronization, that are the key to victory in war zones. Easy to handle and require
less skilled personnel for flying this drone. The main feature is that if we manufacture the entire technology in
India the cost reduction will boom the units and cost per unit will be smashed by 50-70%. So the low cost
drones are the needs of Indian airspace and more over the combat troops can use it on any terrain and in any
kind of weather which will allow them to carry their combat operations in any environment.
