Between Cooperative Creativity and Conflicts on Appreciation: Customer-developer-links in a small software companies

Research on participatory design focuses on scientific projects and model applications; few studies draw on commercial settings. In such settings the customer and its wishes are seen as dominant. The paper explores the nature of customer-developer-links in commercial projects. How can the cooperation between customers and developers be described? Based on case studies made in previous projects, I show that customer-developer-links oscillate between inspiring cooperation and fights for power and appreciation. Is there a chance to improve and professionalize these links? Answering this question needs further research.
Issues in Control of a Robotic Spatial Augmented Reality System

A robotic spatial augmented reality (RSAR) system combines a robotics technology with a spatial augmented reality system (SAR) where cameras are used to recognize real objects and projectors augment information and user interface directly on the surface of the recognized objects, rather than relying on handheld display devices. Moreover, a robotic module is actively used to discover and utilize the context of users and environments. The control of a RSAR system involves several issues from different technical fields such as classical inverse kinematics of motors where projector-camera pairs are mounted, inverse projection problems to find appropriate internal/external parameters of projectors and cameras, and image warping in graphics pipeline to compensate the kinematic constraints. In this paper, we investigate various control issues related to a RSAR system and propose basic approaches to handle them, specially focused on the prototype RSAR system developed in ETRI.
Low Voltage Network Modelling

The presence of electrical vehicles and distributed photovoltaic generation in France is constantly increasing in the home building sector. In this study it is seen how these increments of consumption or production affect to a low voltage network. To achieve this objective, a 100 meters long low network has been modelled. It is made up an aerial and three phase line with a section of 70 mm2 of aluminium. This network supplies electricity to a neighbourhood in France with nine houses. Each home can have electrical vehicles or photovoltaic generation or both. For this study three different profiles have been created. One profile is created with the consumption of the nine different houses, another profile is created for the photovoltaic generations and one more profile is created for the electrical vehicles batteries consumption. In order to calculate the yearly consumption and the yearly Joule losses in this low voltage network, simulations with MATLAB have been done. With these simulations the consumption and Joule losses are calculated for different cases. The first case is that where the neighbourhood has any EV or any PV generation and it is compared with the cases where the neighbourhood has EVs or PV generation or both. A sensibility analysis has also been done in order to see the influence of the EVs charging hour. The yearly consumption and the yearly Joule losses have been calculated for five different cases, one case for each of the five different hours: at 8h, at 17h, at 19h, at 21h and at 00h. For each of these cases, all the EVs start charging at the same time until 5,5 kWh every day. This analysis is realized first without photovoltaic generation and then case with photovoltaic generation. Finally, it is seen that photovoltaic generation reduces the average consumption whereas sometimes Joule losses can be increased; it is also proved that PV generation can help to reduce the impact of electrical vehicles if they are charged during the solar hours. Regarding the EVs, the consumption and Joule losses are increased especially when EVs are charged during the existing peak hours; the best way to charge EVs without increasing Joule losses would be to charge the EVs during the off-peak hours.
Estimating the link between accessibility and productivity with propensity score matching

This thesis consists of three main parts. The first and most important part, in terms of effort and time spent, is devoted to the estimation of the importance of accessibility for production at the firm or plant level using three different econometric estimation approaches. The results could have implications for the calculation of "wider" economic benefits of transport infrastructure, stemming from agglomeration externalities (e.g., scale economies). There are both methodological and result-wise conclusions that can be drawn from this research: methodologically, first, using unbalanced firm-level data requires the use of proxy variables to account for (initial) firm-specific unobserved productivity effects, and non-random exit from the dataset. Second, there are unsolved theoretical problems when applying an essentially aggregate approach to productivity analysis on disaggregate data, viz., relating to the existence of aggregate production functions, and to the aggregation of productivity from a disaggregate level to a more aggregate level in a spatial framework. Result-wise, clear productivity differences are presented, when comparing firms in the same time period but in different locations with different accessibility. However, it is not possible in this dataset to detect increased productivity for representative firms stemming from the opening of the Oresund link. It is therefore discussed whether the reason for this result could be the inappropriateness of output measures in a competitive business environment, where a large portion of the benefits are gradually transferred to consumers and thus remain unmeasured. Other, more comprehensive structural approaches to econometrics, including the demand side of the economy, are also recommended. The second part of the thesis treats an unjustly neglected area of transport research: the validation of transport demand models. These transport models are for example used to calculate the new traffic patterns and changes in accessibility from a transport infrastructure investment like the Oresund fixed link, around which most of this thesis orbits. The third and last part, written with two co-authors, deals with the "vulnerability" of the road network, in terms of effects on the travel time delays of the users when a link is disrupted. The calculated indices of importance and exposure could also be seen as extreme forms of accessibility, especially when there is no alternative route besides the one that is cut-off.

Protein type and lifestyle contribute to the evolution of low complexity regions in proteins of plant colonizing fungi

Background: Interactions between plants and fungi range from mutual symbiosis to parasitism. Fungi secrete proteins (termed effectors) to establish different forms of interactions with host plants. Such proteins are thought to coevolve with their molecular plant targets, and this can favor the emergence of novel alleles of fungal effector proteins. Low complexity regions in protein sequences are abundant in eukaryotes and were shown to contribute to the formation of novel protein sequences. This suggests that low complexity regions may play a role in the evolution of effector proteins. Several effector proteins with low complexity regions were functionally characterized in plant colonizing fungi that showed diverse lifestyles and belonged to different taxonomic groups. To investigate if low complexity regions in fungal effector proteins could contribute to the evolution of different plant-fungus interaction types, I employed publicly available genomic data from 121 species of plant colonizing fungi representing six different lifestyles and three phyla. I classified proteins in each species as cytoplasmic, secreted-non effector or effector protein and predicted low complexity regions in all protein sequences.Results: I found that the fraction of proteins that contain a low complexity region differs between cytoplasmic and secreted proteins. Moreover, the fraction of a protein sequence that spans a low complexity region differed on average between cytoplasmic and secreted proteins. Inferring homologous relationships between effector proteins revealed that this fraction is higher in recent compared to ancestral proteins, suggesting that low complexity regions contribute to the formation of novel effector alleles. Furthermore, a principal component analysis and the results of a generalized linear model showed that the lifestyle of different fungi contributes to the evolution of low complexity regions. Likewise, the relative position of low complexity regions differed between cytoplasmic and secreted proteins, between ancestral and recent effector proteins, and between effectors of different lifestyles.Conclusions: Protein type and lifestyle contribute to the evolution of low complexity regions in proteins of plant colonizing fungi, but molecular and evolutionary mechanisms explaining the differences between different protein types and proteins of different lifestyles remain to be elucidated.
A finite element model of the pedestrian knee-joint in lateral impact

This paper presents a modelling of a human knee joint in lateral impact for use in an explicit finite element code. The articulation between each condyle of the femur and the corresponding tuberosity of the tibia is mainly described. The bones entering into the formation of the knee joint are the condyles of the femur above, the head of the tibia below. The bones are connected together by ligaments, some of which are placed on the exterior of the joint, while others occupy its interior. This model will be impacted both to estimate the severity of knee joint lesions, and predict the risk of knee injuries in car/pedestrian accidents. The effect of the impactor stiffness, velocity, and height will be evaluated. Experimental results from static tests and impact tests, to characterise the mechanical behviour of each part, like the ligaments or the bones, and the whole kinematics of the knee, serve as a basis for the validation of the model.

Communication Enabled Multi-Agent Cooperative Reinforcement Learning Using the Common Information Approach

In this paper using the example of a two-agent matching problem we highlight the applicability of the common information approach from decentralized team problems, for developing low-regret learning schemes for multi-agent cooperative reinforcement learning problems. In our model, one agent is better informed about the environment when compared to the other, and strategically timed (costly) communications from the informed agent are used to increase the common information and to obtain optimal policies when the model is known. We then show how the understanding of the modiﬁed information structure leads to a hierarchical bandit formulation when the model is unknown, and where a modiﬁed Upper Conﬁdence Bound algorithm achieves close to optimal regret. Finally, we also show how Q-learning based schemes apply to a generalization of the basic model.
Computer vision techniques for underwater navigation

In the world of autonomous underwater vehicles (AUV) the prominent form of sensing has been sonar due to cloudy water conditions and dispersion of light. Although underwater conditions are highly suitable for sonar, this does not mean that vision techniques should be completely ignored. There are situations where visibility is high, such is in calm waters, and where light dispersion is not an issue, such as shallow water or near the surface. In addition, even when visibility is low, once a certain proximity to an object exists, visibility can increase. The focus of this project is this gap in capability for AUVs, with an emphasis on computer-aided detection through machine learning and computer vision techniques. All experimentation utilizes the Stingray AUV, a small and unique vehicle designed by San Diego iBotics. The first experiment is detection of an anchored buoy, which mimics the real world application of mine detection for the Navy. The second experiment is detection of a pipe, which mimics pipes in bays and harbors. The current algorithm for this application uses boosting machine learning on hue, saturation, value (HSV) to create a classifier followed by post processing techniques to clean the resulting binary image. There are many further applications for computer- aided detection and classification of objects underwater, from environmental to military
Impact of Crisis Coverage on the Financial Market of Russia

The article examines the impact of informational messages characterizing the crisis in the economy on the financial market indicators. The aim of the article is to build an index that allows assessing the crisis situation in the country based on textual analysis of informational messages. Due to the literature review, the factors determining the crisis in the economy were identified. The empirical base of the study included more than 10 million news texts from various sources accredited by Thomson Reuters. For the first time, the authors compiled a “bag of words” (dictionary) to determine the crisis situation in the country; and by means of the text analysis, they developed the author’s crisis index calculated on the basis of news reports in foreign media about Russia. They conducted the analysis of the relations between the crisis index and the stock index MOEX. According to the results of the study, it has been established that an increase in the number of news reports determining the crisis situation in the economy has a negative effect on the financial market: it leads to a drop in stock prices. Thus, not only objective economic factors, but also the information component influencing the mood of investors and the behavior of economic entities, affects the key indicators of the financial market. The proposed author’s crisis index can also be used to assess other relations, for example, the effect of the crisis on the exchange rate.
Novel Application of Imprinting Lithography for Multi-bit Ferroelectric Memories

This thesis is about an innovative application of nanoimprinting lithography in organic ferroelectric memories, which can achieve multi-bit data storage. Multi-bit data storage, defined here as storage of multiple bits in a single device cell, can potentially make higher density ferroelectric memory at a lower price. The idea is based on ferroelectric response with regard to ferroelectric film thickness. Two kinds of memory cells were fabricated to test the functionality and performance of the proposed concept. After optimizing the thermal nano-imprinting process to replicate periodicity micro-structure to a ferroelectric poly(vinylidene fluoride-trifluoroethylene) film, we first fabricated the ferroelectric capacitor cells with the imprinted polymer film. The fabricated cells, with sizes down to 0.0589 mm^2, showed a promising multi-bit functionality and retention property. Four different imprinting patterns were also compared, the repeating grating structure as line: 20 um / space: 10 um represented the best multi-bit performance in terms of identification of the operation voltage for different bits. A prediction of the imprinting pattern and the ferroelectric capacitor performance were given according to the results. With the same imprinting condition, we also fabricated ferroelectric field effect transistors (FeFETs). The FeFETs with periodicity pattern of line: 20 um / space: 10 um was investigated. It is observed that, the smallest imprinted cell with a gate length of 5 um and width of 5 mm only has several nano-ampere of leakage current, which is 10^5 times smaller than the ON current. Using a drain voltage of 50 mV, states can be read out easily. It is evident that the four states of the system retain distinguishable after the 10^4 second retention test.
Modeling and Testing of Bistable Waterbomb Base Configurations

Origami is making an impact in engineering as solutions to problems are being found by applying origami principles (eg. flat-foldability) and using specific crease patterns as inspiration. This thesis presents an in-depth analysis of a particular origami fold – the waterbomb base – to facilitate its use in future engineering problems. The watebomb base is of interest due to its familiarity to the origami community, simple topology (can be made by folding a single sheet of paper four times), scalability, generalizability, and interesting kinetic behavior. It can behave as a nonlinear spring as well as a one- or two-way bistable mechanism. This thesis presents models of the kinetic behavior of the traditional waterbomb base as well as some non-traditional variants to be used as tools in future development of waterbomb-base-inspired mechanisms. In all cases considered here, developability as well as rotational symmetry in both the geometry and motion of the mechanisms are assumed. The thesis provides an introduction to origami and reviews some of the ways in which it has been studied and applied in engineering fields. The waterbomb base is also presented as a specific origami fold with practical application potential. Models for the behavior of the traditional waterbomb base are introduced and its potential usefulness as a testbed for actuation methods is discussed. Models are developed for its kinematic and bistable behavior, including the forces needed to transition between stable states. These models are validated by comparison to physical prototype testing and finite element analysis. The thesis introduces the generalized waterbomb base (WB) and generalized split-fold waterbomb base (SFWB). The WB maintains the pattern of alternating mountain and valley folds around the vertex but in this generalized case any even number of folds greater than or equal to 6 is allowed. An SFWB is created by splitting each fold of a WB into two “half folds”, effectively doubling the number of folds and links but halving the deflection at each fold. The same models that were developed for the traditional waterbomb base are developed for the WB and the SFWB and a few potential applications are discussed.

Measurements of the Air-Sea Interface from an Instrumented Small Buoy

Abstract : An instrumented spar buoy, Met-on-a-Stick (MOAS), was designed, deployed, and validated for measuring the air sea interface processes at multiple levels. This system was deployed in June 2010 off the coast of California, and January and February 2011 in Monterey Bay. The system provides mean measurements of wind, temperature, and humidity at multiple levels within 3 m above the sea surface and measurements of sea surface temperature at three levels below ocean surface. It is small enough to be deployed and retrieved by two people. This thesis work introduces the design and the instrumentation of the system and evaluates the ability of the system for characterizing near-surface vertical variations of the marine boundary layer. The results indicate that the platform performance is as expected and is capable of providing measurements to characterize the fine variations close to the air-sea interface. We foresee a broad use of the MOAS in the future due to its low-cost and ease of deployment. Future improvements of the system include the use of better wind and GPS sensors to increase the quality of wind and wave measurements from the MOAS.
