Method for SLAM Based on Omnidirectional Vision: A Delayed-EKF Approach

This work presents a method for implementing a visual-based simultaneous localization and mapping (SLAM) system using omnidirectional vision data, with application to autonomous mobile robots. In SLAM, a mobile robot operates in an unknown environment using only on-board sensors to simultaneously build a map of its surroundings, which it uses to track its position. The SLAM is perhaps one of the most fundamental problems to solve in robotics to build mobile robots truly autonomous. The visual sensor used in this work is an omnidirectional vision sensor; this sensor provides a wide field of view which is advantageous in a mobile robot in an autonomous navigation task. Since the visual sensor used in this work is monocular, a method to recover the depth of the features is required. To estimate the unknown depth we propose a novel stochastic triangulation technique. The system proposed in this work can be applied to indoor or cluttered environments for performing visual-based navigation when GPS signal is not available. Experiments with synthetic and real data are presented in order to validate the proposal.
POWERTEST: a tool for energy conscious weighted random pattern testing

Due to the increasing use of portable computing and wireless communications systems, energy consumption is of major concern in today's VLSI circuits. With that in mind we present an energy conscious weighted random pattern testing technique for Built-In-Self-Test (BIST) applications. Energy consumption during BIST operation can be minimized while achieving high fault coverage. Simple measures of observability and controllability of circuit nodes are proposed based on primary input signal probability (probability that a signal is logic ONE). Such measures help determine the testability of a circuit. We developed a tool, POWERTEST, which uses a genetic algorithm based search to determine optimal weight sets (signal probabilities or input signal distribution) at primary inputs to minimize energy dissipations. The inputs conforming to the primary input weight set can be generated using cellular automata or LFSR (Linear Feedback Shift Register). We observed that a single input distribution (or weights) may not be sufficient for some random-pattern resistant circuits, while multiple distributions consume larger area. As a trade-off, two distributions have been used in our analysis. Results on ISCAS benchmark circuits show that energy reduction of up to 97.82% can be achieved (compared to equi-probable random-pattern testing with identical fault coverage) while achieving high fault coverage.
The genomic instability associated with integrated simian virus 40 DNA is dependent on the origin of replication and early control region

DNA rearrangements in the form of deletions and duplications are found within and near integrated simian virus 40 (SV40) DNA in nonpermissive cell lines. We have found that rearrangements also occur frequently with integrated pSV2neo plasmid DNA. pSV2neo contains the entire SV40 control region, including the origin of replication, both promoters, and the enhancer sequences. Linearized plasmid DNA was electroporated into X1, an SV40-transformed mouse cell line that expresses SV40 large T antigen (T Ag) and shows very frequent rearrangements at the SV40 locus, and into LMtk-, a spontaneously transformed mouse cell line that contains no SV40 DNA. Stability was analyzed by subcloning G-418-resistant clones and examining specific DNA fragments for alterations in size. Five independent X1 clones containing pSV2neo DNA were unstable at both the neo locus and the T Ag locus. By contrast, four X1 clones containing mutants of pSV2neo with small deletions in the SV40 core origin and three X1 clones containing a different neo plasmid lacking SV40 sequences were stable at the neo locus, although they were still unstable at the T Ag locus. Surprisingly, five independent LMtk- clones containing pSV2neo DNA were unstable at the neo locus. LMtk- clones containing origin deletion mutants were more stable but were not as stable as the X1 clones containing the same plasmid DNA. We conclude that the SV40 origin of replication and early control region are sufficient viral components for the genomic instability at sites of SV40 integration and that SV40 T Ag is not required.
A New Sparse Channel Estimation and Tracking Method for Time-Varying OFDM Systems

We propose a simple sparse channel estimation and tracking method for orthogonal frequency-division multiplexing (OFDM) systems based on a dynamic parametric channel model, where the channel is parameterized by a small number of distinct paths, each characterized by path delay and path gain, and all parameters are time varying. In the proposed method, we adaptively choose the delay grid and estimate each channel path delay iteratively. To further reduce the complexity, we also propose a tracking algorithm based on the fact that the changes in the channel path number and path delays are small over a few adjacent OFDM symbols. After the physical path delays are estimated, we then estimate the channel path gains by using the polynomial basis expansion model (P-BEM). Simulation results demonstrate the effectiveness of the proposed channel estimation and tracking method in dynamic environments. Compared with the compressive-sensing-based channel estimator using the orthogonal matching pursuit (OMP) algorithm, the new technique proposed here has much lower computational complexity while offering comparable performance.

The 'New' Venture Capital Cycle (Part I): The Importance of Private Secondary Market Liquidity

This paper demonstrates that liquidity gaps disrupt the venture capital cycle. How should this problem be addressed? We offer a new perspective on the venture capital cycle and argue that the emergence of more liquidity options can bridge these gaps. Analyzing the development of secondary marketplaces for private shares in non-listed companies in the United States and similar initiatives in Europe, Israel and India, this paper makes the case that the development of a structured pre-IPO segment in stock markets can remedy the disruptions in the venture capital industry.
RYHMÄOSTAMINEN ELEKTRONISESSA B2C - KAUPANKÄYNNISSÄ

Summanen, Antti Group buying as a part of electronic B2C-commerce marketing strategy Jyväskylä: University of Jyväskylä, 2012, 23 p. Information Systems, Bachelor’s Thesis Supervisor: Makkonen, Markus Group buying has been a significant new phenomenon in web shop pricing. With this new pricing mechanism the customer has a chance to affect the pricing of the product meanwhile the seller can achieve vast competitive advantage. Group buying utilizes customers’ networks effectively via internet and social media. In this study we focus on group buying as a pricing mechanism and as a part of web shop’s marketing strategy. Our purpose is to define the concept of group buying and find out its special features. Group buying is compared to other pricing mechanisms based on these features. The other pricing mechanisms include static pricing and some dynamic pricing mechanisms. Of those special features the diversity of group buying especially stands out. Secondly this study compares two large web shops utilizing group buying, Groupon and LivingSocial, and one already extinct pioneer of the industry, Mobshop.com. Groupon is based in US but is one of the largest competitors in the market in Finland. LivingSocial is also US-based and it is recognized as the Groupons closest competitor. Mobshop.com hasn’t been around in many years but it still stands out with its more diverse pricing mechanism and different pricing range.
Empirical Analysis Of The Impact Of Comprehensive Income On Basic Earnings Per Share For Spanish Companies Listed On Madrid Stock Exchange

In this study we will empirically evaluate the overall impact, and by industries, of Basic Earnings per Share calculated according to Comprehensive Income against the same ratio determined in accordance with Net Income, for a sample of ninety-two Spanish groups listed on the Madrid Stock Exchange during 20042007, in agreement with the information contained in their Consolidated Financial Statements pursuant to IASB GAAP and industry classification adopted in this market. In order to contrast the corresponding hypotheses, a set of non-parametric tools were used, as the data was far from normalcy. The results of our paper, which are ground-breaking at an international level, show a statistically significant impact of Basic Earnings per Share calculated according to Comprehensive Income against the same ratio determined pursuant to Net Income for the sample group in all of the years that were analyzed. On the other hand, when approaching the study by industries, we have observed quite uniform behavior between them in the sense that we found a remarkable impact on listed companies in all industries, which is why in general terms we are witnessing a phenomenon that affects the listed companies regardless of the nature of their business activities. These evidences, apart from suggesting a new dimension in the fundamental analysis, of particular interest to analysts and investors, justifies the disclosure of Basic Earnings per Share determined according to Comprehensive Income, not only in the notes, but also in the main body of the Statement of Comprehensive Income.
Phrenic motoneuron morphology in the neonatal rat

The morphology of neonatal rat phrenic motoneurons was studied following retrograde labeling with horseradish peroxidase, which resulted in Golgi‐like fills of phrenic motoneuron somata and dendrites. At birth, these neurons have well‐developed dendritic trees with many characteristics described for phrenic motoneurons in the adult rat. The dendrites form tightly fasciculated bundles that emerge from the phrenic nucleus primarily along four axes: ventromedial, ventrolateral, dorsolateral, and rostral/caudal, with smaller and more variable projections directly lateral and ventral. Although sparse, some dendritic appendages were also present, and in a few animals, somata clustering was apparent. The most significant difference between adult and neonatal rat phrenic motoneurons is in the extent to which medially and laterally projecting dendrites extend beyond the borders of the ipsilateral gray matter. In the neonate, unlike the adult, these dendrites project extensively past the gray/white border to the edge of the hemicord. Ventromedial dendrites occasionally cross to the contralateral ventral horn in the ventral white commissure and laterally projecting dendrites could be seen reaching the edge of the cord, turning and traveling rostrally or caudally for up to 100 μm. Phrenic motoneurons are not unique in having long dendrites at birth. A brief comparative study showed that neonatal cervical, thoracic, and lumbar motoneurons also have long dendrites that project to the medial and lateral borders of the hemicord.
The state of cooking in England: the relationship of cooking skills to food choice

This article uses data from the 1993 Health and Lifestyles Survey of England to present findings on how, why and when people use cooking skills; where and from whom people learn these skills. The implications for policy are explored. The survey data suggests that socio‐economic status and education are associated with the sources of people’s knowledge about cooking. The first or prime source of learning about cooking skills was reported to be mothers; cooking classes in school were cited as the next most important by the majority of correspondents, with some class and educational variations. The importance of mothers as sources of information on cooking skills is observed in all social classes. What emerges is a population unsure of specific cooking techniques and lacking in confidence to apply techniques and cook certain foods. Women still bear the burden of cooking for the household, with four out of every five women respondents cooking on most or every day, compared with one in five men. This may be related to the large number of men who claim to have no cooking skills (one in five).
Prior muscular exercises affects cycling pattern

The aim of this study was to investigate the effect of concentric or eccentric fatiguing exercise on cycling pattern. Eleven well trained cyclists completed three sessions of cycling (control cycling test (CTRL), cycling following concentric (CC) or eccentric (ECC) knee contractions) at a mean power of 276.8 ± 26.6 Watts. Concentric and eccentric knee contractions were performed at a load corresponding to 80% of one repetition maximum with both legs. Before and after CTRL, CC or ECC knee contractions and after cycling, a maximal voluntary contraction (MVC) test was performed. Cardiorespiratory, mechanical and electromyographic activity (EMG) of the rectus femoris, vastus lateralis and biceps femoris muscles were recorded during cycling. A significant decrease in MVC values was observed after CC and ECC exercises and after the cycling. ECC exercise induced a significant decrease in EMG root mean square during MVC and a decrease in pedal rate during cycling. EMG values of the three muscles were significantly higher during cycling exercise following CC exercise when compared to CTRL. The main finding of this study was that a prior ECC exercise induces a greater neuromuscular fatigue than a CC exercise, and changes in cycling pattern.
The Demand for Emerging Market Bonds

We study the multi-period asset allocation problem for emerging market investors whose asset menu consists of stocks, bonds and bills. We consider two types of emerging market investors: domestic investors (with returns in local currency) and international investors who can invest in US and emerging markets assets (with returns in US dollars). In developed markets, long-term government bonds are often considered attractive investment options for risk-averse investors. Our results show that emerging market bonds with a maturity of one year and longer can be attractive for domestic and international investors with different risk preferences, in both the short run and the long run.
Technology and the customer interface: What consumers want in the physical and virtual store

For companies to realize the benefits of recent innovations in customer interface technology, they need to understand the value consumers place on technology as part of the shopping process. A national survey of 2,120 online consumers was conducted to explore how people want to shop in both online and in-store environments and determine how interactive and conventional media work together to move consumers through the purchase process. The study investigated 128 different aspects of the shopping experience, from common elements to recent innovations. The results indicated that consumers are generally satisfied with the convenience, quality, selection, and value provided by retailers today. They are less satisfied with the level of service provided, the availability of product information, and the speed of the shopping process. The findings suggest that new technologies can enhance the shopping experience, but applications must be tailored to the unique requirements of consumer segments and product categories.
Trabalho, família e bem-estar: factores e padrões de qualidade de vida na Europa

3 This working paper stems from the Quality of Life in a Changing Europe project, which tried to understand how, in an era of sweeping social change, European citizens living and working in a variety of welfare regimes evaluate the quality of their lives. Quantitative data was gathered with a survey applied in eight different countries: Finland, Sweden, The Netherlands, Germany, United Kingdom, Portugal, Hungary and Bulgaria. In each country, workers from four different sectors of activity answered to the survey: retail, telecommunications, banking/insurance and a public hospital. In analytical terms, special attention was given to the impact of resources and demands that originate in the work and family domains, to their articulations and dynamics and also to the impacts they have on satisfaction and well-being levels. The diversity existing between the various countries represented is also considered. Key-words: quality of life, quality of work, work-family balance.
Sp1-Mediated Transcription of the Werner Helicase Gene Is Modulated by Rb and p53

ABSTRACT The regulation of Werner’s syndrome gene (WRN) expression was studied by characterizing the cis-regulatory elements in the promoter region and the trans-activating factors that bind to them. First, we defined the transcription initiation sites and the sequence of the 5′ upstream region (2.8 kb) ofWRN that contains a number of cis-regulatory elements, including 7 Sp1, 9 retinoblastoma control element (RCE), and 14 AP2 motifs. A region consisting of nucleotides −67 to +160 was identified as the principal promoter of WRN by reporter gene assays in HeLa cells, using a series of WRNpromoter-luciferase reporter (WRN-Luc) plasmids that contained the 5′-truncated or mutated WRN upstream regions. In particular, two Sp1 elements proximal to the transcription initiation site are indispensable for WRN promoter activity and bind specifically to Sp1 proteins. The RCE enhances WRN promoter activity. Coexpression of the WRN-Luc plasmids with various dosages of plasmids expressing Rb or p53 in Saos2 cells lacking active Rb and p53 proteins showed that the introduced Rb upregulates WRN promoter activity a maximum of 2.5-fold, while p53 downregulates it a maximum of 7-fold, both dose dependently. Consistently, the overexpressed Rb and p53 proteins also affected the endogenous WRN mRNA levels in Saos2 cells, resulting in an increase with Rb and a decrease with p53. These findings suggest that WRN expression, like that of other housekeeping genes, is directed mainly by the Sp1 transcriptional control system but is also further modulated by transcription factors, including Rb and p53, that are implicated in the cell cycle, cell senescence, and genomic instability.
Orthogonal multicarrier modulations in satellite uplinks

In this paper, we analyze Orthogonal Frequency‐Division Multiple Access and Single‐Carrier Frequency Division Multiple Access as alternative physical layer schemes for the up‐link of a satellite network. Both orthogonal frequency‐division multiple access and single‐carrier frequency division multiple access are orthogonal multicarrier modulations (MCMs). They provide a higher spectral efficiency than the single‐carrier modulations employed today in satellite networks. Unfortunately, MCMs are also more vulnerable to nonlinear distortion, phase noise, and synchronization errors. This has prevented, so far, the use of MCMs in satellite uplinks, where these impairments are very critical. In our analysis, we show that a well‐design MCM system can effectively provide reliable communications in satellite uplinks, even in the presence of nonlinear distortion, phase noise, and synchronization errors.

Thin film based flexible current clamp sensor for green wireless sensor networks

This paper presents a novel film based flexible clamp type current sensor for green wireless sensor networks fabricated by printed silver paste coil using the process technology in screen-printing as a low cost, simple, and rapid method. Since developed sensor has high flexibility, it can be used by winding the cable and drastically reduce the installation space. In addition, it can construct wireless sensor networks easily because wireless terminals can drive autonomously without external power supply by utilizing the secondary current generated in the coil of the sensor by electromagnetic induction. The sensor's output voltage changed linearly with variation of the value of primary current in the 0 to 100 A range. When the value of primary current was 100 A, the output voltage was 69 mV per 150 turns in the coil. Although the ambient temperature around the sensor was raised at 80 °C due to heat evolved by the electric resistance of the coil, there was no almost variation of the voltage. This result indicates the practical applicability as the current sensor for electrical cables.
