Building an electric model vehicle with obstacle avoidance system

In this paper we propose an electric model vehicle with its own system of acquisition and computation of the information, on which we will test the collision control algorithms in indoors and outdoors with GPS localization. The algorithm used in this project is the Potential Field method. We chose to use a LIDAR sensor that can acquire distance data from the environment in 2D. The main objective of these tests is to make obstacle avoidance with mobile robot in Real-Time.
Event-based utilization control for distributed Teal-time Embedded systems

Distributed Real-time Embedded (DRE) systems working in open environments often need to enforce utilization bounds on multiple processors in order to manage CPU resources adaptively even when task execution times are unforeseeable. An event-based utilization control algorithm is proposed, and the algorithm applies to mixed (continuous and discrete) rate adaptation in DRE systems including tasks that support discrete configurations and the ones that support continuous configurations. A mixed integer predictive controller is designed and it is triggered when needed so that overhead can be reduced greatly. The experimental results argue the effectiveness of this algorithm.
New Data Base-independent, Sequence Tag-based Scoring of Peptide MS/MS Data Validates Mowse Scores, Recovers Below Threshold Data, Singles Out Modified Peptides, and Assesses the Quality of MS/MS Techniques*

The Mascot score (M-score) is one of the conventional validity measures in data base identification of peptides and proteins by MS/MS data. Although tremendously useful, M-score has a number of limitations. For the same MS/MS data, M-score may change if the protein data base is expanded. A low M-value may not necessarily mean poor match but rather poor MS/MS quality. In addition M-score does not fully utilize the advantage of combined use of complementary fragmentation techniques collisionally activated dissociation (CAD) and electron capture dissociation (ECD). To address these issues, a new data base-independent scoring method (S-score) was designed that is based on the maximum length of the peptide sequence tag provided by the combined CAD and ECD data. The quality of MS/MS spectra assessed by S-score allows poor data (39% of all MS/MS spectra) to be filtered out before the data base search, speeding up the data analysis and eliminating a major source of false positive identifications. Spectra with below threshold M-scores (poor matches) but high S-scores are validated. Spectra with zero M-score (no data base match) but high S-score are classified as belonging to modified sequences. As an extension of S-score, an extremely reliable sequence tag was developed based on complementary fragments simultaneously appearing in CAD and ECD spectra. Comparison of this tag with the data base-derived sequence gives the most reliable peptide identification validation to date. The combined use of M- and S-scoring provides positive sequence identification from >25% of all MS/MS data, a 40% improvement over traditional M-scoring performed on the same Fourier transform MS instrumentation. The number of proteins reliably identified from Escherichia coli cell lysate hereby increased by 29% compared with the traditional M-score approach. Finally S-scoring provides a quantitative measure of the quality of fragmentation techniques such as the minimum abundance of the precursor ion, the MS/MS of which gives the threshold S-score value of 2.
Localization of passive UHF RFID Labels with Kalman Filter

Abstract. Localization via Radio Frequency Identification (RFID) is frequently used in different applications nowadays. It has the advantage that next to its ostensible purpose of identifying objects via their unique IDs it can simultaneously be used for the localization of these objects. In this work it is shown how Received Signal Strength Indicator (RSSI) measurements at different antennae of a passive UHF RFID label can be combined for localization. The localization is only done based on the RSSI measurements and a Kalman Filter (KF). Because of non-linearities in the measurement function it is necessary to incorporate an Extended Kalman Filter (EKF) or an Unscented Kalman Filter (UKF) where simulations have shown that the UKF performs better than the EKF. Additionally to the selection of the filter there are different possibilities to increase the localization accuracy of the UKF: The advantages of using Reference Tags (RT) or more than one tag per trolley (relative positioning) in combination with an Unscented Kalman Filter are discussed and simulations results show that the localization error can be decreased significantly via these methods. Another possibility to increase the localization accuracy and in addition to achieve a more realistic simulation is the consideration of the angle between reader antenna and tag. Simulation results with the incorporation of different numbers of fixed antennae lead to the conclusion that this is a useful surplus in the localization.
Simulation Testing of LFM Compression Performances Based on Identification

The pulse compression technology is important in radar signal processing, and it already have been used widely. It is necessary to test the performances indexes of the pulse compression system because those indexes indicate the effect of compression. Based on the frequency response identification of the LFM pulse compression system, this paper proposes to test its technical characteristics by simulation. By using this method, not only the fundamental indexes of pulse compression ratio and range side-lobes weighting reduction ability are tested, but also the anti-jamming ability is evaluated conveniently. Besides, In order to validate whether the system up to the design indexes requirement, the comparison with the performance parameter of ideal design model also have been done in this paper.
Scavenger Receptors Mediate the Role of SUMO and Ftz-f1 in Drosophila Steroidogenesis

SUMOylation participates in ecdysteroid biosynthesis at the onset of metamorphosis in Drosophila melanogaster. Silencing the Drosophila SUMO homologue smt3 in the prothoracic gland leads to reduced lipid content, low ecdysone titers, and a block in the larval–pupal transition. Here we show that the SR-BI family of Scavenger Receptors mediates SUMO functions. Reduced levels of Snmp1 compromise lipid uptake in the prothoracic gland. In addition, overexpression of Snmp1 is able to recover lipid droplet levels in the smt3 knockdown prothoracic gland cells. Snmp1 expression depends on Ftz-f1 (an NR5A-type orphan nuclear receptor), the expression of which, in turn, depends on SUMO. Furthermore, we show by in vitro and in vivo experiments that Ftz-f1 is SUMOylated. RNAi–mediated knockdown of ftz-f1 phenocopies that of smt3 at the larval to pupal transition, thus Ftz-f1 is an interesting candidate to mediate some of the functions of SUMO at the onset of metamorphosis. Additionally, we demonstrate that the role of SUMOylation, Ftz-f1, and the Scavenger Receptors in lipid capture and mobilization is conserved in other steroidogenic tissues such as the follicle cells of the ovary. smt3 knockdown, as well as ftz-f1 or Scavenger knockdown, depleted the lipid content of the follicle cells, which could be rescued by Snmp1 overexpression. Therefore, our data provide new insights into the regulation of metamorphosis via lipid homeostasis, showing that Drosophila Smt3, Ftz-f1, and SR-BIs are part of a general mechanism for uptake of lipids such as cholesterol, required during development in steroidogenic tissues.

Application of Taguchi Method in Optimization of Gate Oxide and Silicide Thickness for 45 nm NMOS Device

— The optimization of 45nm NMOS device was studied using Taguchi Method. This method was used to analyze the experimental data in order to get the optimum results. In this paper, there are four factors were varied for 3 levels to perform 9 experiments. S ilicide on the poly-S i gate electrode was used to reduce the gate electrode resistance. The virtually fabrication of 45nm NMOS device was performed by using ATHENA module. While the electrical characterization of device was implemented by using ATLAS module. The values of oxide and silicide thickness after optimization approach were 1.52709nm and 25.26nm respectively. The result of the threshold voltage (V TH) is 0.148468 Volts. In this research, silicide thickness and oxide thickness are the main factors were identified as the source of the inability of the transistors to perform. The oxide thickness also was identified as one of the factors that has the strongest effect on the response characteristics. INTRODUCTION The scaling of the Complementary Metal Oxide Semiconductor (CMOS) devices to smaller physical dimensions has became the driving force for the semiconductor industry to meet the market's demand for greater functionality and performance of the integrated circuit at a low cost [1]. This was the primary activity of advanced device development almost since the basic technology was established. By reducing the device dimensions of the integrated circuits, the device performance can be greatly improved in terms of switch speed [2]. Meantime, the manufacturing cost of each device can also be reduced by decreasing the device dimensions. The reduction of CMOS source/drain depth is important for suppressing MOS punch through leakage and minimize device short channel effect such as drain-induced barrier lowering (DIBL) in submicron CMOS devices [3,4]. In order to minimize short channel effects (SCE) and maximize device performance simultaneously, an advanced source/drain engineering associated with diffusion profiles of source and drain junction should explored for the optimum CMOS device design. The self-aligned silicide (SALICIDE) technology has been widely
Predictors of Early Numeracy: Applied Measures in Two Childcare Contexts

The purpose of the current research was: (1) To assess differences in early numeracy, phonological awareness, receptive language, executive functioning, and working memory for children in two childcare settings (family and center); (2) To determine whether applied measures of phonological awareness and executive functioning could serve as predictors of numeracy performance. Children (N = 89) ranging in age from 39 to 75 months were recruited from state-licensed childcare centers and family childcare homes. Teacher ratings of executive functioning were significantly related to early number skills, phonological awareness, and receptive language, but none of the parent ratings were significantly related to the child scores. The overall model did not differ between center and family childcare children. Phonological awareness was a significant predictor of number skills for both younger and older children. Receptive language skills were the best predictor of early numeracy performance for younger children and the best predictor for older children was phonological working memory measured by a non-words repetition task. These results suggest a connection between children ’ s numeracy skills and a developmental change from receptive language skills to phonological working memory skills.
Developing and Validation of Identifying People in Risk of Addiction Questionnaire (I.P.R.A)

Background Drug addiction is considered as a problem of the new century which has destructive consequences for both family and society. This ominous phenomenon resulted from many factors. Present research aimed at recognition of inter-personal factors related to addiction and were conducted through a questionnaire to identify the youths at risk of addiction. Objectives Present research aimed at recognition of inter-personal factors related to addiction and were conducted through a questionnaire to identify the youths at risk of addiction. Materials and Methods The design of the present research is correlational analytic. The population consists of all young addicted or non-addicted people between the ages 18 to 35 and the sample consists of 82 addicted and 223 non-addicted young people in Tehran who were selected randomly and simply. The initial form included 120 questions which were administered on the sample in three stages. The data was analyzed through descriptive statistic and factor analysis. Results In this questionnaire four factors of depression and miserableness, having a positive attitude to drug, stress and anxiety and finally seeking high levels of excitement were respectively the strongest factors in predicting the risk of drug-abuse and addiction. The validity of the questionnaire which consists of 75 questions in the final form was calculated through internal consistency. Cronbach alpha of the whole questionnaire was 0.97, which that of the factor of depression and miserableness was 0.96, the factor of a positive attitude to drug was 0.93, the factor of stress and anxiety was 0.90 and the factor of high excitement-seeking was 0.80. Conclusions The evaluation of the questionnaire for identifying the individuals in the risk of addiction showed that the questionnaire benefits from appropriate validity and reliability. Therefore, it can be used in preventive fields and research. Moreover, by illuminating interpersonal factors that are effective in drug abuse, proper strategies can be used to prevent drug addiction.
Counting the cost of crime in Italy

We gauge the cost of crime in Italy by concentrating on a subset of offences covering about 64% of total recorded crimes in the year 2006. Following the breakdown of costs put forward by Brand and Price, we focus on the costs in anticipation, as a consequence, and in response to a specific offence. The estimated total social cost is more than €38 billion, which amounts to about 2.6% of Italy's GDP. To show the usefulness of these measures, we borrow the elasticity estimates from recent studies concerning the determinants of crime in Italy and calculate the cost associated with the surge in crime fuelled by unemployment and pardons. Indeed, in both cases such costs are substantial, implying that they should no longer be skipped when assessing the relative desirability of public policies towards crime.
Learn Convolutional Neural Network for Face Anti-Spoofing

Though having achieved some progresses, the hand-crafted texture features, e.g., LBP [23], LBP-TOP [11] are still unable to capture the most discriminative cues between genuine and fake faces. In this paper, instead of designing feature by ourselves, we rely on the deep convolutional neural network (CNN) to learn features of high discriminative ability in a supervised manner. Combined with some data pre-processing, the face anti-spoofing performance improves drastically. In the experiments, over 70% relative decrease of Half Total Error Rate (HTER) is achieved on two challenging datasets, CASIA [36] and REPLAY-ATTACK [7] compared with the state-of-the-art. Meanwhile, the experimental results from inter-tests between two datasets indicates CNN can obtain features with better generalization ability. Moreover, the nets trained using combined data from two datasets have less biases between two datasets.
p27KIP1 Regulates Neurogenesis in the Rostral Migratory Stream and Olfactory Bulb of the Postnatal Mouse

Neuronal progenitor cells of the anterior subventricular zone (SVZa) migrate along the rostral migratory stream (RMS) to the olfactory bulb, where they exit the cell cycle and differentiate. The molecular mechanisms that regulate SVZa progenitor proliferation and cell-cycle exit are largely undefined. We investigated the role of p27KIP1 in regulating cell proliferation and survival in the RMS and olfactory bulb between postnatal day 1 (P1) and P14, the peak period of olfactory bulb neuron generation. A large proportion of cells in the RMS and the olfactory bulb express cytoplasmic p27KIP1, but a small percentage display high nuclear p27KIP1 immunostaining, which exhibit a caudallow–rostralhigh gradient: lowest in the SVZa and highest in the glomerular layer of the olfactory bulb. p27KIP1 is also present in the nucleus and/or the cytoplasm of neuron-specific type III β-tubulin(+) cells. Cells with strong nuclear p27KIP1 expression are BrdU(−) and Ki67(−). The percentage of BrdU(+) cells in the SVZa, RMS, and olfactory bulb is higher in p27KIP1 null than wild-type (WT) mice at all ages analyzed. Consistent with these findings, p27KIP1 overexpression in cultured p27KIP1 null and WT SVZ cells reduced cell proliferation and self-renewal. Finally, in p27KIP1 null mice, the diameter of the horizontal limb of the RMS is larger than in WT mice, and development of the olfactory bulb granule cell layer is delayed, together with increased apoptotic cell density. Our results indicate that in the postnatal brain, p27KIP1 regulates the proliferation and survival of neuronal cells in the RMS and olfactory bulb.
A Highly Doppler Blueshifted Fe-K Emission Line in the High-Redshift QSO PKS 2149–306

We report the results from an ASCA observation of the high-luminosity, radio-loud quasar PKS 2149-306 (redshift 2.345), covering the ~1.7-30 keV band in the quasar frame. We find the source to have a luminosity ~6 × 1047 ergs s-1 in the 2-10 keV band (quasar frame). We detect an emission line centered at ~17 keV in the quasar frame. Line emission at this energy has not been observed in any other active galaxy or quasar to date. We present evidence rejecting the possibility that this line is the result of instrumental artifacts or a serendipitous source. The most likely explanation is blueshifted Fe-K emission (the equivalent width is EW ~ 300 ± 200 eV, quasar frame). Bulk velocities of the order of 0.75c are implied by the data. We show that Fe-K line photons originating in an accretion disk and Compton scattering off a leptonic jet aligned along the disk axis can account for the emission line. Curiously, if the emission-line feature recently discovered in another quasar (PKS 0637-752, z = 0.654) at 1.6 keV in the quasar frame is due to blueshifted O VII emission, the Doppler blueshifting factor in both quasars is similar (~2.7-2.8).
A Birnbaum-Saunders accelerated life model

The 2-parameter family of probability distributions introduced by Birnbaum and Saunders characterizes the fatigue failure of materials subjected to cyclic stresses and strains. It is shown that the methods of accelerated life testing are applicable to the Birnbaum-Saunders distribution for analyzing accelerated lifetime data, and the (inverse) power law model is used due to its justification for describing accelerated fatigue failure in metals. This paper develops the (inverse) power law accelerated form of the Birnbaum-Saunders distribution, and explores the corresponding inference procedures-including parameter estimation techniques and the derivation of the s-expected Fisher information matrix. The model approach in this paper is different from an earlier work, which considered a log-linear form of a model with applications to accelerated life testing. Here, using an example data set, the fitted model is effectively used to estimate lower distribution percentiles and mean failure times for particular values of the acceleration variable. The benefits of having an operable closed form of the Fisher information matrix, which is unique to this article for this model, include interval estimation of model parameters and LCB on percentiles using relatively simple computational procedures.
Relating superembeddings and non-linear realizations

We discuss the relation between the superembedding method for deriving worldvolume actions for D-branes and the method of partially broken global supersymmetry based upon linear and non-linear realizations of SUSY. We give the explicit relation for the cases of space filling branes in three and four dimensions and show that the standard -constraint of the superembedding method is the source of the required covariant non-linear constraints for the PBGS method.
The Genesis of Two-Way Interactive Video and Audio for Teaching Students in Rural, Small Schools: A Model for Implementation.

This study describes how some school districts have implemented full motion, two-way interactive video in rural small schools and communities. A prototype and guidelines for future implementation are presented. Researchers studied 14 school districts in the Oklahoma Panhandle and eastern New Mexico and three sites in Texas where the technology has been or is being implemented. Findings suggest that use of two-way interactive video is growing in the Southwest region, assisting in the delivery of effective education in areas of economic decline. The technology requires the support of dedicated local visionaries who persevere in technology application. Although expensive, this technology is affordable with support from the local business community, particularly the local telephone company or cooperative. Teacher training is essential to the success of implementation. Education delivered by interactive video was considered effective and was well-received in the communities studied.

Performance and Stability Enhancement of Perovskite-Type Nanomaterials Applied for Carbon Capture Utilizing Oxyfuel Combustion

A new series of Ba-Co-Operovskite-type oxygen carriers has been successfully synthesized by the microwave-assisted sol-gel method and further applied for producing an O2/CO2 mixture gas. The oxygen adsorption/desorption performance of synthesized samples was studied in a ﬁxed-bed reactor system. Effects of A/B-site substitution on the oxygen desorption performance of Ba-Co-O–based perovskites are also included. Furthermore, the effects of operating conditions including the adsorption time and temperature as well as the desorption temperature on oxygen production performance were investigated in detail. The results indicated that BaCoO3-δ exhibited an excellent oxygen desorption performance among the synthesized A/B-site–substituted ACoO3-δ and BaBO3-δ samples, and that the optimal adsorption time, adsorption temperature and desorption temperatureforBaCoO3-δ were determined to be 20min, 850◦Cand850◦C, respectively, in this study.
