Search for projects
Emilio Dorigatti, Violetta Toto
Our project is a web platform aimed towards biologists' need to automatically collect and analyze large datasets of cell images. One of the most notable points of this project is the use of a GIS software in the analysis process; in other words we treat cells and tissues as if they were landscapes and analyze them with algorithms originally devised for geography. The platform is entirely web based, thus allowing easy access from anywhere in the world and making possible to share data between research laboratories. It was developed using free and open source components, from the libraries to the image management and elaboration softwares.
Variable Neighborhood Search for the Partition Graph Coloring Problem
Lorenz Leutgeb, Moritz Wanzenböck
Today's "always-on" mentality and increased use of the internet introduces new challenges when designing communication networks. Modern fiber-optic networks can be modelled as mathematical structures to overcome those defiances. This project emphasizes on the distribution of wavelengths (channels) in fiber-optic networks. By solving the Partition Graph Coloring Problem (PCP), the structure of target networks can be optimized in order to eventually save money. The PCP is of non-deterministic polynomial-time complexity, meaning it belongs to the group of problems most difficult to solve. Therefore clever methods must be developed to obtain a solution in reasonable time. An adoption of Variable Neighborhood Search (VNS) for the PCP is proposed and implemented.
Utilization of Korean Traditional Flower Pattern on a Double Soundproofing Screen
Ye-lim Shin, Bokyung Kim, Nayoon Yoo
On a hot summer day, the noise is sometimes too much to bear if the windows are open. However, we cannot ventilate the room if the windows are closed. To solve this problem, research was conducted concerning how to make a screen with soundproofing and ventilation ability. The traditional Korean flower pattern was used in this experiment because this pattern has been used in doors and windows since the ancient times of Korea, and it was expected to have some soundproofing ability. Also, it emphasizes the beauty of the Korean traditional house. It has lots of irregularities, so it has more chances of sound waves to interfere with each other. Thus, it was hypothesized that it can exclude noise better than a grid screen. Also, the traditional flower pattern is a suitable structure for research because it has good air permeability and light penetrability. It was concluded that the soundproofing efficiency of the traditional flower pattern screen is better than the formal grid screen. There were the specific frequencies of particular noises used in this study, and an optimal design, screen material and shape of the screen was determined for the specific noises. From this research, stress due to lound noise can be resolved in ordinary life using flower pattern screens. This screen can be used to reduce noise pollution, and help people enjoy a more pleasant life.

With a polystyrene‐block (sensor support), a UV‐light source (UV lamp which emits UV‐A light), a UV‐measuring device (UV‐radiation, with a measuring sensor), a slide and a protection shield, we analyzed the permeability of UV radiation. Brand and cheap sun protecting products were tested. The measurements showed that most of the sunglasses did well in the experiments. There were substantial differences in the measurements of the sun creams, it turned out that the more expensive products are not always the best!
The sawdust filter to clean water from Pb(II) ions
Akvilė Gintautaitė, Eglė Stonkutė
Water is the source of life. As only 3 percent of water on the Earth is fresh, our responsibility is to keep it clean. The contamination is the one of dangers foreseen for the 21st century. That is why we decided to find an effective and economically acceptable way to clean contaminated water from lead ions, Pb(II). We discovered that sawdust filters could be a reasonable choice. The price of 5 kilograms of sawdust, needed to clean up one cubic meter of contaminated water, is about 3 euro. According to our study, the most efficient sawdust absorbs up to 92 % of lead ions. We found that the most reasonable way to increase efficiency of sawdust significantly is its activation with microwaves, which costs additionally only 1 euro cent per 5 kg of sorbent. In our project we present an eco-friendly way to utilize the used sawdust.
The influence of the economic crisis brought up in 2008 on progressive economies of Brazil, Russia, India and China
Instability of world financial markets can weaken even the strongest economic players. Even the richest countries cannot look to the future with confidence. However, the circumstances from the recent past let the countries with the abbreviation BRIC (Brazil, Russia, India and China) succeed measurably. Their economies were marked by economic growth and positive future prospects. The aim of this project is to characterise the impact of the financial crisis from 2008 on otherwise progressive economies of BRIC countries. In this project we will compare the main macroeconomic and social indicators: status and growth of gross domestic product, gross national income, the rate of foreign debt, balance of the state budget, inflation of consumer prices, production of main commodities and unemployment from economic information about these territories for the years 2007 to 2011. Thanks to the gained information we managed to take a stand on economic situation of each of the BRIC countries and define the negative effect on their economic environment. With the new knowledge we discovered huge differences among countries, which are connected by their economic growth.
The energy of the future: Microbials Fuel Cells
Álvaro Mingote Lladó, Gonzalo Maortua Langdon, Jaime Fernández de Santaella Sunyer
In this project we propose a new enhanced model (88.6% cheaper and 7% more efficient) for a microbial fuel cell. After several experiments where heated the battery, we reached the conclusion that the increase of the temperature will reduce the voltage. On the other hand, after trying many different concentrations of glucose (0-111mM), we can assert that an addition of glucose, found in this interval, will provoke an increase of the potential of, at least, 300 mV. With the researches done about bacteria of the anode we are able to claim that 2 possible species might have the capacity of producing electricity: Coccus Gram-negative and Propionibacteriumsp. Finally, we studied the change of the voltage over time. We observed that there are three stages: adaptation, exponential growth, and plateau.
The chameleon robot
Adrielle Rakotomalala, Aymeric Jacquin, Benjamin Lazard
The aim of our project is to develop a small mobile robot, remotely piloted with a Smartphone, and able to hide in its environment by taking the color of the ground on which it operates. To do so, we used RGB LED matrixes coupled with sensors, that can identify the ground color, and a system able to receive and interpret the information provided by the Smartphone, using Bluetooth, in order to control the motors that ensure the mobility of our robot. It features independent zones, each being able to mock up the color of a portion of the ground beneath the robot (so that it can be camouflaged on a multicolored checkerboard). The principle of our robot, extended to a larger scale, could for example be used in the military field, in order to cover substantial systems like tanks. We can also imagine, following the same principle, spy robots, wildlife photography, etc..
The Recycling of Abandoned Silk Selvage as Silk Paper
Junsu Kwon, So Hyun Park
Jinju in korea is one of the world's five major silk production city. The quality of pearl silk is known as very high, but we have yet to know about it. Each time, 10% of high-grade silk is discarded on silk separation process. This discarded silk is called 'Selvage'. Selvage is classified as an environmental waste so someone has to pay a considerable amount of money to discard the selvage according to Environmental Wastes Control Act. Therefore, we wanted to recycle the selvage as a raw material of paper. We made some paper with selvage and measured durability, flexibility, dyeing property, warmth retaining properties, hygroscopicity, and flame resistance of them. When the mass ratio of selvage was increased, durability, dyeing property, flexibility, warmth retaining properties, moisture absorption, and flame resistance were enhanced. So we could make a High-quality paper this way. We can also utilize these silk paper as wallpaper and material for paper crafts.
The Ecological Benefits from Intercropping Bioenergy Plant (Switchgrass) and Grain Crop (Maize)
The cultivation of bioenergy plants in large areas could occupy cropland that will threaten food safety. To solve this contradiction, we proposed a new technology by intercropping bioenergy plant switchgrass, with common crop maize, taking the advantages of differences in their developmental features and rooting depths. In this study, soil quality, microbe and biomass were assessed by comparing intercropping with cropping each alone. The results showed that, as compared with single cropping of maize, (1) the intercropping could enhance soil aggregates, organic matter, and nutrients (N、P、K) significantly by 27.40%, 25.99%, 21.88%, 64.13% and 11.51%, respectively; (2) the intercropping could increase soil microbial numbers, microbial biomass and microbial functional diversity by 45.70%, 34.50% and 24.61%, respectively; (3) The intercropping could also increase crop biomass and economic value by 24.79% and 41.82%, and reduce CO2 emission by 21.47%, respectively. Therefore, the extension of intercropping bioenergy plant and grain crop will improve soil environment the land values and simultaneously improve food production and bioenergy development.
