Path following of an omni-directional four-wheeled mobile robot

Navigation of omni-directional four wheeled mobile robot usually is done by trajectory tracking controller. But, in this article two methods of path following have been presented to reach this purpose. Path following is another navigation approach that is solved some of trajectory tracking navigation systems difficulties like `turning back'. Path following navigators usually are designed by two different viewpoints, geometrical approaches or control approaches which both are utilized in this paper. The main contribution of this paper is to present tow simple methods with acceptable navigation performance. Based on the simulation results, it is proofed that, the presented methods are able to navigate the robot on desired paths even in hard situations like measurement delay and external disturbance. Also, advantages of each method is presented based on comparison of simulation results. Another contribution of this work is using dynamic model of the robot instead of kinematic model which is usually is used in path following articles. To reach this goal, at the first step, a Linear Quadratic Regulator (LQR) controller is designed as low level controller, then path following navigator is mounted on high level controller. Note that, weighting matrix of LQR controller (matrix Q) is calculated by Genetic Algorithm to achieve the best possible time performances.
Decision-making impairments in women with binge eating disorder in comparison with obese and normal weight women.

OBJECTIVE The purpose of the current study was to examine decision making in female patients with binge eating disorder (BED) in comparison with obese and normal weight women. METHOD In the study, 20 patients with BED, 21 obese women without BED and 34 healthy women participated. Decision making was assessed using the Iowa Gambling Task (IGT). Several questionnaires were administered measuring binge eating severity, sensitivity for punishment and reward, and self-control. RESULTS The findings indicated that the BED and obese group performed poorly on the IGT. Participants who have BED and are obese did not improve their choice behaviour over time, whereas participants with normal weight showed a learning effect. An association between IGT performance and binge eating severity was found. CONCLUSION This study demonstrates that patients with BED display decision-making deficits on the IGT comparable with other forms of disordered eating. Future research should focus on unravelling the processes underlying the deficits.
A study of 12 specifications of the library problem

The author studies twelve specifications for a seemingly simple database problem and demonstrates many approaches for classifying informally stated problem requirements. She compares the specifications according to how they address problems of the library example to illustrate the imprecision of natural-language specifications and how twelve different approaches to the same set of informal requirements reveal many of the same problems. The comparison suggests which issues should be addressed in refining an informal set of requirements and shows how these issues are resolved in different specification approaches. <<ETX>>
Spectroscopy of Red Giants in the Large Magellanic Cloud Bar: Abundances, Kinematics, and the Age-Metallicity Relation

We report metallicities and radial velocities derived from spectra at the near-infrared calcium triplet for 373 red giants in a 200 arcmin2 area at the optical center of the LMC bar. These are the first spectroscopic abundance measurements of intermediate-age and old field stars in the high surface brightness heart of the LMC. The metallicity distribution is sharply peaked at the median value [Fe/H] = -0.40, with a small tail of stars extending down to [Fe/H] ≤ -2.1; 10% of the red giants are observed to have [Fe/H] ≤ -0.7. The relative lack of metal-poor stars indicates that the LMC has a "G dwarf" problem, similar to the Milky Way. The abundance distribution can be closely approximated by two Gaussians containing 89% and 11% of the stars, respectively: the first component is centered at [Fe/H] = -0.37 with σ = 0.15, and the second at [Fe/H] = -1.08 with σ = 0.46. The dominant population has a metallicity distribution similar to that of the LMC's intermediate-age star clusters. The mean heliocentric radial velocity of the sample is 257 km s-1, corresponding to the same center-of-mass velocity as the disk (measured at larger radii). Because of the central location of our field, kinematic constraints are not strong, but there is no evidence that the bar deviates from the general motion of the LMC disk. The velocity dispersion of the whole sample is σv = 24.7 ± 0.4 km s-1. When cut by metallicity, the most metal-poor 5% of stars ([Fe/H] < -1.15) show σv = 40.8 ± 1.7 km s-1, more than twice the value for the most metal-rich 5%; this suggests that an old, thicker disk or halo population is present. The age-metallicity relation (AMR) is almost flat during the period from 5 to 10 Gyr ago, with an apparent scatter of ±0.15 dex about the mean metallicity for a given age. Comparing this to chemical evolution models from the literature, we find that a burst of star formation 3 Gyr ago does not reproduce the observed AMR more closely than a steadily declining star formation rate. The AMR suggests that the epoch of enhanced star formation, if any, must have commenced earlier, ≈6 Gyr ago—the exact time is model dependent. We compare the properties of the LMC and the Milky Way, and discuss our results in the context of models that attempt to use tidal interactions with the Milky Way and Small Magellanic Cloud to explain the star and cluster formation histories of the LMC.
Applying ant colony optimization to solve constrained forest transportation planning problems

Problems related to the transport of timber products from harvesting sites to conversion facilities have traditionally involved finding routes that minimize timber hauling and road construction costs. However, increasing environmental concerns have introduced negative impacts (i.e. soil erosion and water quality) into forest transportation planning problems (FTPP) making them larger and more complex. In this paper, we present an algorithm based on the ant colony optimization (ACO) framework, which has been shown to efficiently solve large-scale and complex multi-objective and constrained optimization problems. We used the algorithm to solve FTPP with fixed and variable costs as well as side constraints. Sediment yields expected to erode from road surfaces due to the heavy traffic of log trucks represented the negative environmental impact of timber transport and were considered as a side constraint. Our ACO algorithm used a two-stage process to find the least-cost set of routes from each timber sale location to selected mills resulting in a total sediment yield below a maximum allowable amount. During Stage I, the algorithm uses only sediment yield information on each road segment to quickly find feasible solutions. During Stage II, sediment and cost information per road segment are considered to select feasible solutions resulting in least-cost routes. After a solution is built, a 1-opt local refinement procedure was implemented to improve solution quality. First, we applied our ACO algorithm to a medium scale, gridshaped hypothetical FTPP with 500 road segments (where traffic is allowed on both directions), 25 timber sale locations, and a single mill destination. Four cases with increasing levels of sediment constraints were considered, and an exhaustive parameter search process was conducted to select the best parameter combination for each case. To test the robustness of the ACO-algorithm, we created 10 different FTPP instances with different timber sale locations and destination nodes for the same hypothetical problem. Solutions were then compared with those obtained from comparable mixed-integer programming formulations solved by CPLEX.
Concurrent orchestration in Haskell

We present a concurrent scripting language embedded in Haskell, emulating the functionality of the Orc orchestration language by providing many-valued (real) non-determinism in the context of concurrent effects. We provide many examples of its use, as well as a brief description of how we use the embedded Orc DSL in practice. We describe the abstraction layers of the implementation, and use the fact that we have a layered approach to demonstrate algebraic properties satisfied by the combinators.
Material-specific neural correlates of memory retrieval

It is well established that the neural activity engaged during memory retrieval varies with the kinds of information that are recovered. Less well established is whether this activity reflects online recovery of information, or processes operating downstream of successful recovery. We used event-related potentials (ERPs) to adjudicate between these alternatives, emphasizing that an online recovery account would be supported if material-specific indices of successful retrieval occurred no later than a material-independent index of recollection, the left-parietal ERP old/new effect. A contrast between ERP correlates of successful memory retrieval for words and for faces revealed material-specific neural activity that onset as early as the left-parietal old/new effect. These findings suggest that the material-specific neural activity indexes the online recovery of encoded information.
Old Wine in a New Bottle: Seeking Sustainability among the Earth Keepers

proud of his family, whom he gave the best of goods, vacations, and a lovely house. He began an energetic transnational life, with his family inNewYork and his successful business inCuba. Then a financial crisis and Castro’s nationalization of private businesses forced Miguel to flee to Puerto Rico, where he reestablished his business. His last years were tragic; a thief enticed him, stealing his every penny. He also lost Louise, who tried to protect what little there was left. He died on October 17, 2006. “Cultural relativism” as a sacred and uncomplicated principle of anthropology can no longer be taken for granted. Feminism, human rights, democracy—rising primarily from the “West,” or the United States—override the cultural practices and values of a people. The world is torn by harsh and antagonistic ideological battles. Mendel simply could not take feminism, which he thought the root cause of people’s loss of respect for him. He was an enormously talented man with deep compassion and love for his wife and his daughter, and yet could not see why they sought independence. He saw no wrong in the double standard he practiced. In this excellent study, the daughter-anthropologist captures the father’s beliefs and their roots without scorn and with compassion. The book will appeal to many young students in the United States, even if the boleros are too alien and slow compared with their contemporary music. With the reestablishment of diplomatic relations between the two countries in 2015, Cuba has become an important tourist destination. But its history, experienced by Mendel/Miguel, is familiar; the problems of immigrants and their lives are receiving heightened attention today. A broad range of readers will bring their own life experiences and scholarship to learn from this book. It is an excellent candidate for large introductory courses as well as a variety of courses in anthropology, geography, international/ global studies, Jewish studies, and Latin American/Caribbean studies; graduate courses onmethods; andmany others.We all will find here an opportunity to reflect on how we should represent the other. Finally, Routledge offers an innovative electronic version of My Father’s Wars, with 100 hyperlinks that add richness to thewritten text. This serves as amodel to scholars who wish to pack their data alongside their text and allows electronically savvy young students to access additional sources.
DESIGN AND ANALYSIS OF MODEL PREDICTIVE VOLTAGE AND CURRENT CONTROLLERS FOR THREE PHASE VOLTAGE SOURCE INVERTER IN MICRO GRID

Nowadays renewable energy sources are essential to meet the real power demand. All the Distributed Energy Resources are connected to the common grid through three phase Voltage Source Inverter (VSI). The reliable operation of microgrid can be achieved by controlling three phase voltage source inverter. Voltage and frequency of the Distributed Energy Resources are continuously varying and they depend on nature. While interfacing Distributed Energy Sources to the common grid, both variables must be maintained constant. And these variables are controlled by controlling three phase voltage Source Inverter. The two loop model predictive current and voltage controller is proposed in this paper for voltage source inverter operation. The outer voltage control loop is for controlling frequency and voltage which gives reference input to the inner loop model predictive current controller. The inner current loop generates signal to regulate the inverter current. The Space Vector Pulse Width Modulation Signal Generator is used for voltage commands. The performances of the both controllers are analyzed for various load conditions. Simulation is carried out in MATLAB.
FPGA Based Run Time Reconfigurable Gas Discrimination System

In this paper a gas discrimination system based on five classification algorithms including K nearest neighbors (KNN), multi-layer perceptron (MLP), radial basis function (RBF), Gaussian mixture model (GMM) and probabilistic principal component analysis (PPCA) has been presented. A Committee machine (CM) is used in which the results from each classifier are first transformed to confidences and then a weighted combination rule is used to generate the final decision result. In order to overcome the problem of very high computational complexity of the CM requiring large amount of hardware resources, we propose a novel time multiplexing hardware implementation using a dynamically reconfigurable field programmable gate array (FPGA) platform. The system is successfully tested for combustible gas identification application using our in-house tin-oxide gas sensors.

Lexical inference as a spatial reasoning problem

Humans are often able to draw plausible conclusions from incomplete information based on background knowledge about the world. As a substantial part of this background knowledge is of a lexical nature, a crucial challenge in automating plausible reasoning consists in learning how different words are semantically related. This paper argues that most of the lexical relations that we need for plausible reasoning can be identified with qualitative spatial relations in semantic spaces, i.e. highdimensional Euclidean spaces in which words are represented as geometric objects. This leads us to treat lexical inference as a qualitative spatial reasoning problem, and allows us to combine distributional representations with relation extraction methods and existing lexical resources.
Learning other Agents' Preferences in Multiagent Negotiation

In multiagent systems, an agent does not usually have complete information about the preferences and decision making processes of other agents. This might prevent the agents from making coordinated choices, purely due to their ignorance of what others want. This paper describes the integration of a learning module into a communication-intensive negotiating agent architecture. The learning module gives the agents the ability to learn about other agents' preferences via past interactions. Over time, the agents can incrementally update their models of other agents' preferences and use them to make better coordinated decisions. Combining both communication and learning, as two complement knowledge acquisition methods, helps to reduce the amount of communication needed on average, and is justified in situations where communication is computationally costly or simply not desirable (e.g. to preserve the individual privacy).
Critical success factors for information systems outsourcing management: a software development lifecycle view

Information systems (IS) outsourcing is a serious commitment -- a formal relationship underpinned by a contractual agreement, with long-term consequences among two or more organisations. Many organisations end up frustrated as they learn that their attempts at IS outsourcing have failed. However, some failures could be avoided with knowledge of common pitfalls and critical success factors of such IS outsourcing contracts. This paper investigates essential aspects of IS outsourcing management during the software development life cycle. The survey results are reported in conjunction with findings in the literature of similar studies in other markets, and unique contributors to IS outsourcing in this particular context in the South African corporate market, are identified.
Impact of 5'-amp-activated Protein Kinase on Male Gonad and Spermatozoa Functions

As we already know, the male reproductive system requires less energetic investment than the female one. Nevertheless, energy balance is an important feature for spermatozoa production in the testis and for spermatozoa properties after ejaculation. The 5'-AMP-activated protein kinase, AMPK, is a sensor of cell energy, that regulates many metabolic pathways and that has been recently shown to control spermatozoa quality and functions. It is indeed involved in the regulation of spermatozoa quality through its action on the proliferation of testicular somatic cells (Sertoli and Leydig), on spermatozoa motility and acrosome reaction. It also favors spermatozoa quality through the management of lipid peroxidation and antioxidant enzymes. I review here the most recent data available on the roles of AMPK in vertebrate spermatozoa functions.
Functional Categories in the Lexicon

Stowell (1981) demonstrates that nominal phrases in VP or PP are subject to certain constraints which are not pertinent in the domain of NP or AP. Nominal phrases in VP or PP are obligatory and they must be realized in a position which is adjacent to the head of the phrase (i.e., in a phrase marker; “V° NP” or “P° NP”). In contrast, nominal phrases in NP or AP are optional and do not have to be adjacent to the head. There is a systematic exception to this generalization in the lexically determined class of nouns known as Bare NP adverbs (cf. Larson 1985). Nominal phrases headed by one of this class of nouns appear optionally in VP and they are not required to be adjacent to the verb.
Olig1 and Sox10 Interact Synergistically to Drive Myelin Basic Protein Transcription in Oligodendrocytes

The oligodendrocyte lineage genes (Olig1/2), encoding basic helix-loop-helix transcription factors, were first identified in screens for master regulators of oligodendrocyte development. OLIG1 is important for differentiation of oligodendrocyte precursors into myelin-forming oligodendrocytes during development and is thought to play a crucial role in remyelination during multiple sclerosis. However, it is still unclear how OLIG1 interacts with its transcriptional cofactors and DNA targets. OLIG1 was reportedly restricted to mammals, but we demonstrate here that zebrafish and other teleosts also possess an OLIG1 homolog. In zebrafish, as in mammals, Olig1 is expressed in the oligodendrocyte lineage. Olig1 associates physically with another myelin-associated transcription factor, Sox10, and the Olig1/Sox10 complex activates mbp (myelin basic protein) transcription via conserved DNA sequence motifs in the mbp promoter region. In contrast, Olig2 does not bind to Sox10 in zebrafish, although both OLIG1 and OLIG2 bind SOX10 in mouse.
Smart sorting of H.264/AVC encoded sequences for applications over UMTS networks

In this paper we propose a novel sorting mechanism suitable for H.264/AVC NALUs used in applications over UMTS networks. Each packet contains encoded information elements referred to a certain number of MBs. Following the standard, all the encoded information associated to a single MB is stored sequentially. In this work we propose to group the bits referring to a certain information element type even if associated to different MBs. The benefit of the proposed method will be discussed for different scenarios.
A Left Turn Assist Application using Wireless Vehicle-to-Vehicle Communications at Unsignalized Intersections

We present a wireless vehicle-to-vehicle communications-based safety application to assist drivers with safe left turns at unsignalized intersections. When a potentially dangerous situation such as an oncoming vehicle from the opposite lane is detected, our system can provide the driver with a warning. Our system gives advisory or imminent warnings according to the predicted accident levels through a HMI. For a performance test of our application, we configured three test scenarios and tested our system with vehicles on a proving ground. The test results showed 93% success rates.
