SENTIMENT ANALYSIS IN FRENCH FOR IMPROVING SERVICES AND PRODUCTS : A DEEP LEARNING APPROACH.

Sentiment analysis is a process of evaluating an opinion expressed in a piece of text to determinate the writer’s feeling whether it is positive, negative . or neutral. In this field of study, a lot of researchers have used machine learning approach or deep learning approach in their works to evaluate the sentiment expressed in a text. Most of them have used English words using and very few were interested in other languages. Taking this into account, we present a deep learning approach for sentimental analysis using French text. The approach is based on Convolutional Neural Networks for text classification. The goal of this paper is to use convolutional neural network architecture to classify the sentiment expressed in a given French text about services and products. The model build get a brief text of restaurant and laptop reviews as input and determines the sentiment polarity in each sentence as output. To prove the effectiveness of our approach, we have run experiments in two-channel i.e.CNN-rand and CNN-static. To determine the effectiveness of this approach for classifying French text, we conducted experiments in two-channels: CNN-rand and CNN-static. We obtained encouraging results for CNN-rand with 75.44% for restaurant domain and 74.64% for laptop domain. And with CNN-static we got 82.46% for restaurants and 81.16% for laptops.
Incentivizing Bandit Exploration: Recommendations as Instruments

We study a multi-armed bandit learning setting where a social planner incentivizes a set of heterogeneous agents to efficiently explore the set of available arms. At each round, an agent arrives with their unobserved private type that determines both their prior preferences across the actions as well as their action-independent confounding shift in the rewards. The planner provides the agent with an arm recommendation that may alter their belief and incentivize them to explore potentially sub-optimal arms. Under this setting, we provide a novel recommendation mechanism that views the planner’s recommendations as a form of instrumental variables (IV) that only affect agents’ arm selection but not the observed rewards. We construct such IVs by carefully mapping the history–the interactions between the planner and the previous agents–to a random arm recommendation. Despite the unobserved confounding shift in the rewards, the resulting IV regression provides reliable estimates on the mean rewards of the actions and enables the social learning process to minimize regret over the long term.

Testing the forest refuge hypothesis in sub-Saharan Africa using species distribution modeling for a key savannah tree species, Senegalia senegal (L.) Britton

Quaternary geographic range dynamics of savannah tree species are still not fully understood. The forest refuge hypothesis postulates that climatic and vegetational upheavals during the Pleistocene fragmented the previously continuous ranges of many species into isolated refuges that would have acted as shelters for rainforest taxa and allowed their survival through the Pleistocene cold stages. This hypothesis has recently been applied to studies of taxa in the African savannahs. We here test this hypothesis using the savannah tree species Senegalia senegal (L.) Britton. , which is widely distributed across sub-Saharan Africa. Specifically, we ask the following questions: (i) Do we find evidence for savannah refugia during the last 130,000 before-present in sub-Saharan Africa? (ii) Would the climate in West Africa already have been suitable for S. senegal prior to the Last Glacial Maximum (LGM)? Using 1,132 occurrence records,we modeled the geographic distribution of S. senegal and projected the model into the past using climatic conditions from four time slices spanning the last 130,000 years bp. Our analyses show that the projected geographic extent of S. senegal was broader during the Last Interglacial, with a dramatic decline during the LGM and the subsequent recovery through the mid-Holocene to the present day. Our results indicate a range expansion at least from the mid-Holocene to the present and further show that S. senegal had similarly continuous distribution during the LGM as found today in sub-Saharan Africa. We also assessed the regional variation of environmental niche occupancy using a principal components analysis (PCA). The PCA reveals variation in the occupancy of environmental space across sub-Saharan Africa, a key indication of a wide ecological amplitude exhibited by the species. This study provides insights into the ancestral distribution and the temporal dynamics of a key savannah species that have shaped its current areas of occupancy.
Multi Carrier Based New Random Pulse Width Modulation For Three Phase Inverters

PWM strategies are key options for extracting the quality controllable outputs from the VSI. The objectives involved in the different PWM strategies are improving the primary indices namely, enhancing the fundamental components, reducing the total harmonic distortion, minimizing the switching loss, specific removal of harmonic components etc. while the secondary Issues like suppressing the electromagnetic interference, spreading the harmonic power etc., are also to be considered in contemporary applications. This paper is disquiet about an enhancing the harmonic power dispersal of PWM strategies. The RPWM strategies cover non-predictable harmonic pattern and called as non-deterministic PWM strategies. The inverter is working under RPWM which generate the output harmonic spectra isolated and constantly distributes across frequencies and acoustic noise is also reduced. The paper has proposed a host of carrier based RPWM schemes to enhance the performance of the VSI and implemented them in FPGA involved digital platform. Power dissipation and Speed are presented in detail in term of resource use in FPGA. The RPWM technique is simulated by using time efficient co-simulation (Mat lab-Simulink) methodology.
Investigate Impacts, Challenges And Solutions Of Requirement Engineering In Agile Methodologies: A Review

: Requirement Engineering is one of essential phase in software development life cycle. In the last few years many people know much about the success rate of Requirement Engineering in a project’s success. The agile approach will produce a high standard product in less budget and time. With the passage of time, consumers will be more appealing as their technology standards increase rapidly every day. Agile software development (ASD) is an iterative and gradual approach to development that relies on the participation of customers in the development process. So, we can conclude that organizations are still struggling with agile evolution and agile values, especially when it comes to user involvement. Although much research has been carried out on the role of requirement engineering in agile methodologies and practices, more studies are still needed. The aim of this research is to analyze and compare researchers ' work, which will help those who are interested in finding interesting research fields in this area. Requirement engineering impacts the agile approach tremendously.
Population structure of the tanaid Sinelobus stanfordi (Richardson, 1901) (Crustacea, Tanaidacea) associated with roots of the water hyacinth Eichhornia azurea (Sw.) Kunth. (Liliiflorae, Pontederiaceae), from a coastal lagoon in southern Brazil

This study aimed to investigate the population structure of Sinelobus stanfordi (Richardson, 1901) (Malacostraca,Tanaidae) in a coastal lagoon in the North coast in the Rio Grande do Sul state. The collections were performed weekly on banks of the aquatic hyacinth Eichhornia azurea (Sw.) Kunth during three months. Samples of water hyacinth were manually collected and washed on a sieve of 0. 250μm mesh size. In the laboratory, the material was sorted and the tanaid lengths were measured and classified into following morphotype categories: Manca, Juveniles, Non-Reproductive Females (NRF), Preparatory Females (PREPF), Ovigerous Females (OVF) and Males. The distribution by frequency of body length classes presented a higher abundance of manca in the class of 0.75mm; juveniles in 2.19mm; non-reproductive females in 2.5mm; preparatory females in 2.7mm; ovigerous females in 2.85mm and males in 2.81mm. The average of sexual rate was 3.1:1 (females: males). It was observed the recruitment and predominance of juveniles in the eleven studied weeks, and the presence in lower proportion of PREPF, OVF and males. Based on the analyses of the population structure observed and data found in the literature, became evident the presence of juveniles, females and males during all the year, beyond a continuous reproduction activity of the species. The results have also suggested the species seems to have an opportunistic behavior, being able to colonize a high diversity of substrates. Keywords: Coastal lagoon, macrobenthos, populational structure, Tanaidacea.
Verification of the Efficiency of Alternate Furrow Irrigation on Amount of Water Productivity and Yield of Onion at Sekota Woreda

Efficient water use becomes an important issue in recent years because of the lack of available water resources in some areas is increasing and a serious problem. Globally and more particularly in developing Countries, changing water availability and quality is a complex problem, and management options are not easy. Therefore Partial rootzone drying is a practice of using irrigation to alternately wet and dry (at least) two spatially prescribed parts of the plant root system to simultaneously maintain plant water status at maximum water potential and control vegetative growth for seasonal plant development. The experiment was conducted on the 2017/2018 irrigation season at the irrigation scheme of Sekota woreda. Three irrigation methods alternating furrow irrigation (AFI), conventional furrow irrigation (CFI), and fixed furrow irrigation were verified on separate plots. The design of the experiment was RCBD with four farmers as replications. Each irrigation method was used a 75% amount of irrigation water for five days irrigation interval for verified irrigated onion. The results show that total irrigation water applied in the AFI and FFI treatment was roughly half (3038 m3) that applied to the CFI treatment (6078 m3). There was a significant reduction in irrigation water used with the AFI but a non-significant reduction on the onion yield production. The AFI water productivity was astatically significantly different from FFI and CFI. The water productivity obtained 4.05 kg m-3 with AFI and 3.16 kg m-3 with FFI which was nearly double the 2.15 kg m-3 with CFI. Alternate furrow irrigation (AFI) is gaining interest as a means of saving water while minimizing loss in crop production. In the AFI system, the total water used was half of the CFI system. Rather than using 6076 m3/ha of water for 1 hectare in the CFI system, it is possible to double the irrigated area to 2 hectares in the AFI system. The onion needs a high amount of irrigation water during the development stage, but in the FFI system, as half of the root stays dry throughout the growth period, continuous stress significantly reduces fresh bulb yield.
Study protocol of a cross-sectional and longitudinal mixed-methods study

Background: Clinical empathy has been associated with positive outcomes for both physicians and patients such as: more accurate diagnosis and treatment, increased patient satisfaction and compliance, and lower levels of burnout and stress among physicians. International studies show mixed results regarding the development of empathy among future physicians associating medical education with decline, stability or increase in empathy levels. These mixed results are due to several study limitations. In Denmark, no investigation of Danish medical students’ empathy trajectory has yet been conducted wherefore such a study is needed that optimizes the study design of earlier studies. Methods: The aim of the study is to examine and analyze empathy levels and empathy changes among Danish medical students from the four medical faculties in Denmark, employing a cross-sectional and longitudinal mixedmethods design including a control group of non-medical students. By supplementing cross-sectional and longitudinal questionnaire studies with a focus group interview study it is the aim to identify and analyze factors (including educational) that are perceived by medical students to influence the development of empathy and its expression in clinical care. Discussion: The results of the study will provide insight into the trajectory of medical students’ empathy and in undergraduate and graduate students’ experiences with and perceptions of empathy development. In addition, the study will provide evidence to support further research on how targeted educational programmes can best be designed to educate empathic and patient-centered physicians.
Neuronal transplants used to repair ischemic lesions in the rat central nervous system : histological, immunohistochemical and electrophysiological characterization of development and function

Cerebral ischemia can be caused by many diverse conditions such as cardiac arrest and severe hypotension and is often the cause of secondary brain damage following head injury or infantile birth trauma. The inadequate cerebral blood flow can result in the permanent loss of essential brain circuitries and neurological deficits. Since methods are not currently available for the prevention of neuronal loss following cerebral ischemia, experiments were undertaken to investigate whether transplanted neurons had the potential to afford some measure of repair. In the present study a model was developed whereby the hippocampal CA1 region of the rat brain could be lesioned by transient forebrain ischemia and subsequently repopulated with suspensions of fetal hippocampal tissue. Histological, immunohistochemical and electrophysiological techniques were used to examine the functional capabilities of the transplanted neurons by assessing their ability to survive when transplanted into the degenerating brain region, to develop intrinsic properties characteristic of the cells they had replaced and, to integrate into the host tissue by reestablishing some of the normal synaptic circuitries. The ability of the transplanted neurons to remain viable when placed into a degenerating environment was confirmed by the histological demonstration of ^H-thymidine labelled neurons in the lesioned region and the demonstration that the transplanted neurons were electrically active. Histological and immunohistochemical techniques showed that the transplanted neurons developed cytological features that were indistinguishable from their normal counterparts, showed a remarkable degree of organization, and expressed some of the same neuron specific proteins; specifically calbindin-D2gj£ and parvalbumin. Acetylcholinesterase histochemistry and retrograde axonal transport of Fluoro-Gold demonstrated that some afferent and efferent fibre projections could be reinstated.

It successfully tracked the presence of stroke clots through color differences in color plots.
Bend-it

Elastically deforming wire structures are lightweight, durable, and can be bent within minutes using CNC bending machines. We present a computational technique for the design of kinetic wire characters, tailored for fabrication on consumer-grade hardware. Our technique takes as input a network of curves or a skeletal animation, then estimates a cable-driven, compliant wire structure which matches user-selected targets or keyframes as closely as possible. To enable large localized deformations, we shape wire into functional spring-like entities at a discrete set of locations. We first detect regions where changes to local stiffness properties are needed, then insert bendable entities of varying shape and size. To avoid a discrete optimization, we first optimize stiffness properties of generic, non-fabricable entities which capture well the behavior of our bendable designs. To co-optimize stiffness properties and cable forces, we formulate an equilibrium-constrained minimization problem, safeguarding against inelastic deformations. We demonstrate our method on six fabricated examples, showcasing rich behavior including large deformations and complex, spatial motion.
Fuzzy Logic Based Lane And Green Time Selector For Intersection For Smart Urban Traffic Control

: With the rapid development of automobile industry, urban traffic congestion is becoming more prominent, effective control of traffic lights has become the most important means of control of traffic management and control of network operation. So, how effective real-time traffic signal control, protection of urban transport efficient and orderly operation of the majority of scholars is a hot issue of concern. Traffic congestion is one of the most critical transportation issues facing us, and it is only predicted to get worse during the next years. However, there are techniques and strategies to help in solving this problem. This objective of this research is to provide a methodology for designing traffic signal controllers with a new approach. This new approach uses fuzzy logic to achieve a more efficient control of traffic signals at intersections using the information and expert knowledge of the system. System constitutes of central hub for decision making, magnetic sensors on each lane for vehicle counting and zigbee transceiver system which sends and receives data from sensors and provides to central hub where data is collected from all lanes and in each round and basis of no. of vehicles and mode of traffic, fuzzy logic based lane selector selects the lane which should be green for coming round and fuzzy logic based green time selector provides the time span for which it should be green. By doing this, there is no loss by empty times and traffic runs smoothly for all the lanes. Present system can be implemented din busy and congested areas to increase the traffic flow.
Involucrin and envelope competence in human keratinocytes: Modulation by hydrocortisone, retinyl acetate and growth arrest

Involucrin accumulation and ionophore-assisted envelope for mation, markers of keratinocyte differentiation, were found to be highly dependent on culture conditions in the malignant epidermal keratinocyte line, SCC-13, derived from a human squamous cell carcinoma. In confluent cultures, approximately one-half of the cells were competent to form envelopes when grown in medium without hydrocortisone or retinyl acetate supplementation. Ad dition of hydrocortisone to the medium during growth resulted in up to 90% competence, while addition of retinyl acetate instead resulted in as low as 10% competence. Hydrocortisone partially antagonized the effect of retinyl acetate when both agents were added together. Involucrin levels, measured by radioimmunoassay, were modulated essentially in parallel with envelope com petence under the various conditions tested. When the cells were grown in medium supplemented with hydrocortisone, the levels shortly after confluence were over 50-fold higher than in sparse cultures. Regardless of hydrocortisone or retinyl acetate addition, less than 1% of the cells were competent in sparse cultures of growing cells, but up to 90% exhibited this property after growth arrest in serum-free medium containing hydrocortisone. High levels of competence were correlated with cessation of cell division but not with loss of colony-forming efficiency; under optimal conditions, two-thirds of the cells were capable of both envelope formation and colony initiation. Normal human epidermal cells showed a 4to 5-fold increase in envelope competence from sparse to confluent culture but were insensitive to the suppressive effect of retinyl acetate. The results suggest that some potential differentiated character of malignant keratinocytes may be suppressed in vivo by physiological agents such as vitamin A.
