Animation involves rapidly displaying a sequence of images to create the illusion of movement. There are two main types of animation: cel animation which changes images from one frame to the next, and path animation which moves an object along a predetermined path. 3D animation involves modeling objects, defining their motion, and rendering to add attributes like color. Computer animation employs the same principles as traditional cel animation by setting frame rates and using techniques like morphing, warping, and virtual reality.

2-Axis Gyroscopes for Optical Image Stabilization: STMicroelectronics L2G2IS ...Yole Developpement
Complete reports and comparison of the latest generation products for smartphones from the leading optical image stabilization gyro players.
2-Axis Gyroscopes for Optical Image Stabilization (OIS) constitute a market where 123 million units were shipped in 2015, according to Yole Développement. This market originates only from high-end smartphones and two players share most of it: InvenSense, with 49%, and STMicroelectronics, with 39%.
The 2-axis gyroscopes are located inside the camera module of high-end smartphones. The main constraints are a small footprint and, more importantly, thinness.
Previously, thickness was the same as standard land grid array (LGA) or quad flat no-leads (QFN) package, close to 1mm. Now the standard is 0.65mm, which products from both InvenSense and STMicroelectronics attain.
InvenSense was first, with the IDG-2030, a 2.3x2.3x0.65mm gyroscope, which is still the smallest on the market. Since its introduction we found it in several smartphones from various manufacturers. The IDG-2030 uses the same Nasiri platform as other InvenSense inertial devices, with wafer-level integration of the MEMS sensor on top of the application specific integrated circuit (ASIC), thus providing only one die in the final LGA package.
Months later, STMicroelectronics released the L2G2IS, which shares the same dimensions. The device is manufactured using the same THELMA process as all STMicroelectronics inertial devices. The THELMA platform involves a two-die approach that is challenging for very thin package integration. However, both players now offer very low-cost gyros thanks to die size reduction and process optimization.
Both gyroscopes analyzed are 2-axis X, Y (Pitch, Roll). The two reports can be purchased separately or together in order to compare the technology and pricing of the main smartphone OIS gyro players, including previous generation products.

This document provides an overview and user's guide for the CALMET meteorological model (Version 5). CALMET is a diagnostic and prognostic meteorological model that generates three-dimensional wind, temperature, and moisture fields for use in air quality dispersion models like CALPUFF. It was originally developed by Sigma Research Corporation for the California Air Resources Board to provide time-varying meteorological inputs for air quality modeling over large domains with complex terrain. The document describes the model algorithms, input and output files, processing steps, and options to generate the meteorological fields for use in air quality modeling.
The document describes the design of an autonomous robot that clears undesirable objects from its area using four subsystems: a motion subsystem to move the robot, a detection subsystem using sensors to identify targets and boundaries, a catch and throw subsystem to collect and remove targets, and a power subsystem to supply energy to the other subsystems. The robot is controlled by two Arduino microcontrollers that coordinate the subsystems to autonomously scan its area, detect and capture targets, and remove them from the bounded field.
Optimizing the Performance of an Unpredictable UAV Swarm for Intruder DetectionDaniel H. Stolfi
In this paper we present the parameterisation and optimisation of the CACOC (Chaotic Ant Colony Optimisation for Coverage) mobility model applied to Unmanned Aerial Vehicles (UAV) in order to perform surveillance tasks. The use of unpredictable routes based on the chaotic solutions of a dynamic system as well as pheromone trails improves the area coverage performed by a swarm of UAVs. We propose this new application of CACOC to detect intruders entering an area under surveillance. Having identified several parameters to be optimised with the aim of increasing intruder detection rate, we address the optimisation of this model using a Cooperative Coevolutionary Genetic Algorithm (CCGA). Twelve case studies (120 scenarios in total) have been optimised by performing 30 independent runs (360 in total) of our algorithm. Finally, we tested our proposal in 100 unseen scenarios of each case study (1200 in total) to find out how robust is our proposal against unexpected intruders.

Quantum Variables in Finance and Neuroscience Lecture SlidesLester Ingber
Background
About 7500 lines of PATHINT C-code, used previously for several systems, has been generalized from 1 dimension to N dimensions, and from classical to quantum systems into qPATHINT processing complex (real + $i$ imaginary) variables. qPATHINT was applied to systems in neocortical interactions and financial options. Classical PATHINT has developed a statistical mechanics of neocortical interactions (SMNI), fit by Adaptive Simulated Annealing (ASA) to Electroencephalographic (EEG) data under attentional experimental paradigms. Classical PATHINT also has demonstrated development of Eurodollar options in industrial applications.
Objective
A study is required to see if the qPATHINT algorithm can scale sufficiently to further develop real-world calculations in these two systems, requiring interactions between classical and quantum scales. A new algorithm also is needed to develop interactions between classical and quantum scales.
Method
Both systems are developed using mathematical-physics methods of path integrals in quantum spaces. Supercomputer pilot studies using XSEDE.org resources tested various dimensions for their scaling limits. For the neuroscience study, neuron-astrocyte-neuron Ca-ion waves are propagated for 100's of msec. A derived expectation of momentum of Ca-ion wave-functions in an external field permits initial direct tests of this approach. For the financial options study, all traded Greeks are calculated for Eurodollar options in quantum-money spaces.
Results
The mathematical-physics and computer parts of the study are successful for both systems. A 3-dimensional path-integral propagation of qPATHINT for is within normal computational bounds on supercomputers. The neuroscience quantum path-integral also has a closed solution at arbitrary time that tests qPATHINT.
Conclusion
Each of the two systems considered contribute insight into applications of qPATHINT to the other system, leading to new algorithms presenting time-dependent propagation of interacting quantum and classical scales. This can be achieved by propagating qPATHINT and PATHINT in synchronous time for the interacting systems.

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.

Mission objectives
Chosen category: Come Back
Modality: 350grams Cansat, International Class
Our Cansat will be launched from an experimental rocket. During its flight, it will have to use its
components to control the wing it is flying under, in order to land on a precise point on the ground. During
the whole mission, that is to say right before the rocket’s launch, the Cansat will be autonomous. No direct or
indirect action (using telemetry) will be performed by the team during the flight.
Before the launch, the target GPS coordinates will be sent using uplink telemetry to the Cansat, so that it
will be able to drive its parafoil to the target. The direction is modified by two servomotors. That allows us to
turn right or left and to go faster (by pulling both of the direction lines). All the GPS data is managed by an
ATXMEGA microcontroller, and then sent to our homemade telemetry ground station.
During the flight, the Cansat will continuously be sending position, temperature, pressure, as well as
batteries state information. When ejected, a jack cable, attached to the rocket’s body, will disconnect and
enable the trajectory calculation. The direction wheels are allowed to move after the parafoil has entirely
deployed. The GPS data then allow the microcontroller to calculate the path of the Cansat and its moves (due
to atmospheric conditions, wind...), in order to reach the predefined target on the ground.

2. Recovery Subsystem
- Chosen system: parafoil wing
Main handmade parafoil wing dimensions: 350 x 600 mm
The Cansat is hanging up under a parafoil wing, which enables us to control the path of the module.
The wing is tied to the Cansat with two main lines (fastening lines). Two other thinner lines allow changing
the direction (direction lines). The microcontroller sends orders to two servomotors. On each servomotor is
fixed a wheel, on which direction lines are attached. It enables to pull or release the line. That permits to go
straight, right, left and faster (by pulling both of the direction lines at the same time, because each line is
independent). That allows us to have high manoeuvrability, to forecast and react to different atmospheric
conditions (wind, heat, air pockets...).
Our parafoil wing has been developed with the help of the Aerazur enterprise, specialized in military
recovery systems. Our contact was a great help for the construction and development of the wing, but also
gave us a lot of indications during our tests, of what was wrong, and what had to be changed. This part of the
CLES FACIL page 6 of 17 02/28/2010
7. PDR – Preliminary Design Review
project, certainly the most important, is also the hardest to us. Instead designing a mathematical model of the
wing, we choose to make many tests, and to rectify each seen problems, with the help of this expert.
- Tests
In order to test the parafoil elements (hooks, lines, nodes,...) we suspended a mass of 6 kg (20G * 300g) on
the structure. Giving little shocks to simulate wind, we verified the good resistance of the structure and
fixation points.
- Parafoil in the Rocket Cargo Bay
During the tests, we have chosen a wing folding, which enables fast deployment and stabilisation of
the parafoil. In order to keep the parafoil folded like expected, we added an extractor. First, a parachute fixed
to a line imprisoning the parafoil wing opens and stabilises the module. This will help us to reduce the fall
speed of the Cansat after ejection from the RCB, in order to have no shock that destabilizes the parafoil
wing. Once the system is stabilised to small speed, the parachute wing separates (flies away separately) and
the parafoil wing opens at minimum speed. The flight algorithm then takes control of the parafoil wing in
order to reach the aim on the ground.
Once the parafoil wing is folded, it will be inserted in a bag suspended to a small extractor parachute.
The dimensions of the folded system are approximately the same as the Cansat ones that is to say: diameter
70mm, length 150mm.

radio (x) : number of wires
- Estimation of the power consumption – foreseen duration of the batteries (must be at least 1h
power supply for all the equipments): the total current consumption is approximately 750mA.
This consumption strongly depends on which subsystems are activated, for example disabling
the radio transmitter considerably reduces the consumption.
- List description of the main components selected
o GPS: gives the latitude, longitude and altitude of the module. It enables to locate the
Cansat in the air, and to calculate its trajectory.
o Temperature sensor: a NTC directly connected to the µC ADC gives us the
temperature around the Cansat
o Pressure sensor: gives a temperature compensated pressure. This data enables us, after
conversion, to know precisely the Cansat’s altitude.
o Radio module: this bidirectional radio module can be used as well for data transmission
or reception (the same modules are used aboard the Cansat and in the ground station).
o Servomotors: the servomotors enable us to precisely know the angle of the wheel and
its position, in order to have a perfectly controlled trajectory.
o Microcontroller chip: the µC used and included in the Cansat structure is an AtXmega
128A microcontroller from ATMEL. This 16-bit microcontroller allows us to execute a
consequent program, processing data from the sensors, and compute the flight algorithm.
CLES FACIL page 9 of 17 02/28/2010
10. PDR – Preliminary Design Review
This chip is the brain of the Cansat; it registers sensors data, controls the servomotors
and communicates with the ground station via the radio.
4. Communication Subsystem
- Frequency used for data transmission/reception between the Cansat and the Ground Station:
o 869.65 MHz (downlink and uplink)
- Maximum emission level (W)
o 500 mW
- Maximum bandwidth (-6dB)
o 25kHz
- Transmission protocol
o GFSK modulation + proprietary protocol
5. Flight Software
- Flight software algorithm and programming language
The flight algorithm is implemented onboard the Cansat µC in the C language.
The main lines of the algorithm program are following:
- if there is not enough or just the time to reach the target : straight flight to the landing point
- if there is much time to reach the aim: following a virtual circle trajectory around the landing point,
aka “Eagle Flight”.
The algorithm calculates all the possible trajectories to reach the same goal, after evaluation of the
surrounding flight conditions (wind, pressure...). Then, it chooses one that has the less curves, in order to
have no straight turns to perform, reducing the possibilities of destabilisation and gap between foreseen and
real trajectory.
The two servomotors enable us to react to unforeseen weather inconveniences: heat holes, fast winds, etc.
With the direction (turning right or left), we will be able to go faster by pulling on both lines or by releasing
them in the same time.
During the mission, there is no data stored onboard the Cansat.
All the data is transmitted to the GSE with a radio downlink in real-time.
A proprietary frame is sent in real time to the GSE:
- Raw data collected by the sensors:
o GPS data: all the data is decoded onboard the Cansat, then sent to the GSE and used to
calculate the trajectory.
CLES FACIL page 10 of 17 02/28/2010
11. PDR – Preliminary Design Review
o Temperature sensor: all the data is collected by the µC’s ADC and then sent to the GSE
by radio.
o Pressure sensor: the sensor gives us directly the digital pressure.
- Status information:
o Ejection performed, sensors status, servomotors position
6. Ground Support Equipment (GSE)
The GSE has entirely been developed by the Cles Facil. All the components are settled in a military-like
case. The main components are the following:
o Radio module: the same module as in the Cansat receives the sensors data (RX only
during the flight) and sends orders given by joystick (used only during the test phase,
disabled during the contest).
o A laptop computer: during the Cansat flight, it receives all the sensor data and saves it,
in order to directly draw graphs, in order to have directly readable results. That allows us
to verify the data correctness and magnitude in real time, during the flight. During the
test phase, a joystick is connected, in order to control the Cansat from the ground and to
test its flight possibilities.
The GSE is an autonomous system, all packed in a military-like case. It uses a proprietary technology
developed for previous projects, including sounding rockets. It is quite complex in its conception, as it can be
used for many projects. It includes a high-capacity battery that allows a complete autonomy above 5h of
working.

12. PDR – Preliminary Design Review
C. Test & Certification Campaign
To perform our tests, we followed many different levels of testing our wing’s flight:
1. Wing tests: the Cansat is thrown from a building (25 meters height), containing all of his
components, but inert. The main goal of this test is to obtain a straight flight, when there is no wind.
After this test, we are sure the parafoil is ideally positioned and fixed to the module.
The same tests are then made with bad weather. Finally, we test and choose a wing folding, so it will
be in the RCB. At this point, the wing is correctly integrated to the Cansat.
2. Flight tests: in order to check out our direction system, we drive the Cansat with our GSE Joystick
(drive algorithm disabled). That allows us to look if the Cansat is acting like we want him to, with
enough flexibility and in the good conditions.
3. Ejection and parafoil opening tests: the Cansat is thrown from a higher place (small RF helicopter,
parachutist plane...). The goal of this test is to see if the wing opens and stabilises when thrown with
an initial speed.
4. Algorithm test: thrown from a RF helicopter (~100m high), we check the flight algorithm.
5. The final launch test is performed from a plane, with the algorithm. We also can check all the
sequences of the flight and correct the final problems.

13. PDR – Preliminary Design Review
D. Operations
- 11/01 to 12/31: definition of the project and conception, preliminary design, purchase of the main
parts (mechanical and electrical parts)
- 01/01 to 02/28: first structure and integration prototype built, development of the flight algorithm
- 03/01 to the competition date: tests in flight conditions
1. Mission timeline
We are currently developing this part of the project, which depends of the flight tests. A foreseen timeline for
the Launch day will be sketched, specifying the role of each team member during the CanSat preparation,
integration, GSE setup, operation and recovery. We have already done a first version of this document during
our tests, but it is not finalized. The final week will be used for last testing in real conditions, as a pre-flight
simulation. The timeline will also be completed then.
1 – Preliminary tests: checking of the transmission, taking of the weather conditions, goal GPS coordinates,
battery levels
2 – Cansat is ON, radio transmission is enabled
3 – Cansat is loaded in the RCB (warning: the radio will be turned ON before and while the rocket is
standing on the Launch Area).
4 – Final pre-flight radio transmission tests
5 – Rocket launch
6 – Cansat ejection, first data verification during the flight on our GSE.
7 – Cansat recovery, data exploitation

2. Data Analysis
The GSE receives all the data from the sensors and information from the flying Cansat as described before.
All the data is saved on the laptop computer in CSV files. Those data arrays can immediately after the flight
be exploited with graphs tracing, Matlab calculating.
These quick exploitation possibilities will allow us to see immediately during and after the flight what was
wrong or the different issues, thanks to the sensor data and the status received on ground.
