JUMRv1: A Sentiment Analysis Dataset for Movie Recommendation

Nowadays, we can observe the applications of machine learning in every field, ranging from the quality testing of materials to the building of powerful computer vision tools. One such recent application is the recommendation system, which is a method that suggests products to users based on their preferences. In this paper, our focus is on a specific recommendation system called movie recommendation. Here, we make use of user reviews of movies in order to establish a general outlook about the movie and then use that outlook to recommend that movie to other users. However, a huge number of available reviews has baffled sophisticated review systems. Consequently, there is a need to find a method of extracting meaningful information from the available reviews and use that in classifying a movie review and predicting the sentiment in each one. In a typical scenario, a review can either be positive, negative, or indifferent about a movie. However, the available research articles in the field mainly consider this as a two-class classification problem—positive and negative. The most popular work in this field was performed on Stanford and Rotten Tomatoes datasets, which are somewhat outdated. Our work is based on self-scraped reviews from the IMDB website, and we have annotated the reviews into one of the three classes—positive, negative, and neutral. Our dataset is called JUMRv1—Jadavpur University Movie Recommendation dataset version 1. For the evaluation of JUMRv1, we took an exhaustive approach by testing various combinations of word embeddings, feature selection methods, and classifiers. We also analysed the performance trends, if there were any, and attempted to explain them. Our work sets a benchmark for movie recommendation systems that is based on the newly developed dataset using a three-class sentiment classification.
Expectation Violation Enhances the Development of New Abstract Syntactic Representations: Evidence from an Artificial Language Learning Study

Prediction error is known to enhance priming effects for familiar syntactic structures; it also strengthens the formation of new declarative memories. Here, we investigate whether violating expectations may aid the acquisition of new abstract syntactic structures, too, by enhancing memory for individual instances which can then form the basis for abstraction. In a cross-situational artificial language learning paradigm, participants were exposed to novel syntactic structures in ways that either violated their expectations (Surprisal group) or that conformed to them (Control group). First, we established a potential expectation to hear feedback that simply repeated the same structure as that just experienced. We then manipulated feedback so that the Surprisal group unexpectedly heard passive structures in feedback following active sentences, while the Control group only heard passive structures following passive sentences. Delayed post-tests examined participants’ structural knowledge both by means of structure test trials (focusing on the active / passive distinction, with both familiar and novel verbs), and by a grammaticality judgment task. The Surprisal group was significantly more accurate than the Control group on the structure test trials with novel verbs and on the grammaticality judgment task, suggesting participants had developed stronger abstract structural knowledge and were better at generalising it to novel instances. Tentative evidence suggested the Surprisal group was not significantly more likely to become aware of the functional distinction between the two structures.
Processing and Improving a Head-Related Impulse Response Database for Auralization

To convert a database of anechoic head-related impulse responses [HRIRs] into a set of data that is suitable for auralization involves many stages of processing. The output data set must be precisely corrected to account for some circumstances of the recording. It must then be equalised to remove colouration. Finally, the database must be interpolated to a finer resolution. This paper explains these stages of correction, equalisation, and spatial interpolation for a frequently-used data set obtained from a KEMAR dummy head. The result is a useful database of HRIRs that can be applied dynamically to audio signals for research and entertainment purposes.
The two-echelon multi-products location-routing problem with pickup and delivery: formulation and heuristic approaches

The two-echelon location-routing problem (LRP-2E) considers the first-level routes that serve from one depot a set of processing centres, which must be located and the second-level routes that serve customers from the opened processing centres. In this paper, we consider an extension of the LRP-2E, where the second-level routes include three constraints that have not been considered simultaneously in the location routing literature, namely multi-product, pickup and delivery, and the use of the processing centre as intermediate facility in the second-level routes. This new variant is named two-Echelon Multi-products Location-Routing problem with Pickup and Delivery (LRP-MPPD-2E). The objective of LRP-MPPD-2E is to minimise both the location and the routing costs, considering the new constraints. The first echelon deals with the selection of processing centres from a set of potential sites simultaneously with the construction of the first-level routes, such that each route starts from the main depot, visits the selected processing centres and returns to the main depot. The second echelon aims at assigning customers to the selected processing centres and defining the second-level routes. Each second-level route, starts at a processing centre, visits a set of customers, through one or several processing centres, and then returns to the first processing centre. We present a mixed-integer linear model for the problem and use a Cplex solver to solve small-scale instances. Furthermore, we propose non-trivial extensions of the nearest neighbour and insertion approaches. We also develop clustering-based approaches that have not been extensively investigated with regards to location routing. Computational experiments are conducted to evaluate and to compare the performances of the proposed approaches. The results confirm the effectiveness of clustering approaches.
A Strategic Perspective on Manufacturing Engineering : Revisiting the Literature

This paper presents a literature review of different contexts of manufacturing engineering. The review draws on literature that elaborates on the subject from the fields of strategy, product development, organizational science and human resource management. In this paper it is argued that, in addition to its important role in product development, manufacturing engineering has a strategic aspect as well, and that this strategic aspect can be demonstrated by the function of manufacturing engineering as an important link between product and process, at least in Japanese automobile companies. In addition, differences between manufacturing engineering in Japan and the West are discussed and explanations of the causes of these differences are provided. The main review findings are analyzed in the discussion section and finally unresolved issues that offer a promising avenue for extending the research on manufacturing engineering are presented.

Dairy chemistry and physics

Milk and products made from it affect the lives of a large proportion of the world’s population. Many dairy products are consumed at times and in places far removed from the point at which the milk was produced. This is made possible by the chemical and physical treatments and fractionations applied to milk by modern technology. These treatments are designed to preserve the nutritional value of the milk constituents in the form of palatable products. As food technology in general becomes more advanced and more sophisticated, there is less need for specific commodity technology; on the other hand, there is more need for specific knowledge of raw materials and the effects of various processing treatments on them.
Negative bias temperature instability induced single event transient pulse narrowing and broadening

The effect of negative bias temperature instability (NBTI) on a single event transient (SET) has been studied in a 130 nm bulk silicon CMOS process based on 3D TCAD device simulations. The investigation shows that NBTI can result in the pulse width and amplitude of SET narrowing when the heavy ion hits the PMOS in the high-input inverter; but NBTI can result in the pulse width and amplitude of SET broadening when the heavy ion hits the NMOS in the low-input inverter. Based on this study, for the first time we propose that the impact of NBTI on a SET produced by the heavy ion hitting the NMOS has already been a significant reliability issue and should be of wide concern, and the radiation hardened design must consider the impact of NBTI on a SET.
Physiological response to exercise in the Icelandic horse

This thesis examined the exercise physiology of the Icelandic horse by: 1) studying physiological response in stallions and mares of different ages performing a true breed evaluation field test (BEFT); 2) comparing the effect of ridden tolt and trot at three speeds on physiological response; 3) evaluating physiological response to a simulated 100 m flying pace race; 4) measuring the effect of increasing body weight ratio (BWR) of rider to horse (20, 25, 30, and 35 %) on physiological response in an standardised incremental field exercise test at tolt at 5.4 m/s; and 5) determining the effect of rider on physiological response. In all studies, speed, distance, heart rate and breathing frequency were recorded and plasma lactate concentration, haematocrit and rectal temperature were measured before and after the exercise tests. The main results of this thesis were that Icelandic horses performed high intensity exercise during the true gait tests (BEFT and pace race) and, depending on the weight of the rider, the horses at the medium speed tolt and trot (~5.5 m/s) typical of leisure horses also temporarily performed high intensity exercise. Anaerobic metabolism was crucial for performance at pace. Aerobic fitness was higher in stallions than in mares and age had a limited effect on the physiological response in BEFT, although 4-year-old horses had lower aerobic capacity than older age groups. Peak heart rate decreased with age. There were only minor differences in physiological response to tolt and trot in a group of experienced adult Icelandic horses. There was an effect of rider, with physiological response increasing with increased BWR of rider to horse. Trained and experienced Icelandic horses may exceed their lactate threshold at medium speed (~5.5 m/s) at BWR common for Icelandic horse-rider combinations. Post exercise plasma lactate concentrations were correlated with recovery heart rate. Thus by recording recovery heart rate, trainers of Icelandic horses can get an estimate of post exercise plasma lactate concentration, which reflects the extent of anaerobic metabolism and workload. Overall, the results suggest that training of aerobic and anaerobic metabolism is important for BEFT performance and that training of anaerobic metabolism is of critical importance for pace performance.
Copyrights and Creative Copying

People invest their time, energy and resources to produce a broad variety of copyrightable works of original authorship for an expansive array of reasons, many of which appear economically irrational. This makes it impossible to offer defensible generalizations about the effect, if any, that copyright laws have upon human creators, their artistic impulses, and the decision making underlying the formation of creative works. Nevertheless, it seems highly probable that authors can be negatively affected by the specter of copyright infringement suits in a manner that burdens and chills the creative process. Exact, whole-text copying can be avoided by authors aspiring to copyright compliance, but inspirational, stylistic copying may be more difficult, and problematic, to elude. Many authors strive for unqualified uniqueness in their work for reasons generally unrelated to copyright, but may still unintentionally incorporate into their creative output elements of other works to which they have been exposed. Some authors consciously reference other works, but if they undertake affirmative steps to acknowledge their influences and credit existing works for inspiration, they may actually increase the likelihood of being sued for copyright infringement. In both cases, copyright-related strategizing may unproductively deplete time, energy, and financial resources that might otherwise be used in creative endeavors. Creating new works would appear less perilous, and be more effectively promoted, if the act of copying was less freighted with fear of copyright-infringement accusations. This essay considers just one fragment of this vast and complicated picture: the scope of the substantial similarity doctrine. Though judges sometimes do a good job of defining substantial similarity with appropriate narrowness, in other instances courts have found substantial similarity far too readily, fomenting unwarranted fear, uncertainty, and legal fees. The solution is simply more consistent judicial curtailment of the reach of substantial similarity grounded copyright infringement liability, whether in the context of copyright holders' reproduction rights, or derivative works rights.

METHODS FOR MAINTAINING TRANSIT SERVICE REGULARITY

Maintaining regular transit service has been a chronic operational problem that affects both travelers and operators. Although many researcher have studied aspects of this problem, major limitations of previous work have resulted in the recommendation of procedures that are neither representative of nor operational in the transit management environment. The development of a method for maintaining service regularity through improved scheduling and real-time control based on models developed and validated from empirical data is described. The method is simple to employ and does not require extensive data from the transit agency considering its implementation. Also included is a case study describing the application of the method to three routes in Los Angeles. The results indicate that the procedure can produce resonable solutions and demonstrate its potential value to the transit community.
Devising A Method of ‘Expected Damage’ Estimation for a Polyphagous Invertebrate Pest Exotic to Western Australia

With increasing efficiency in human and freight transport fuelled by the creation of the global market place, pressure is mounting on quarantine administrators to target their resources strategically. A managed approach to decision-making is therefore becoming an integral part of quarantine management since target species and/or entry pathways must be identified and policed effectively. Using the example of Melon Thrips in Western Australia, this paper presents an economic framework that allows decision-makers to prioritise exotic pests based on the damage and production cost increases they are capable of imposing on affected industries. In doing so it identifies a critical level of expected damage associated with the pest that can then be used as a ceiling for incursion response expenditure.
What Professional Development Practices Support The Successful Integration Of Technology Within A Standards-Based Educational (SBE) System

The purpose of this quantitative study was to explore the relationship between K-12 teachers’ current technology skill level, their self-efficacy as teachers, and their attitude toward changes required to integrate 21st-century technologies into their classrooms. Twenty-five members of the teaching staff from a rural School Department in Maine participated. This study describes the following: (a) What is the relationship between teachers’ current skills/ability using technology and their attitude towards integrating 21st-century technologies in the classroom? (b) What is the relationship between teachers’ current self-efficacy towards using technology, and their capacity towards integrating 21st-century technologies in the classroom? and (c) What components of professional development, measured through survey data, are required to support change and prepare teachers to successfully integrate 21st-century technologies in the classroom? This study evaluated data from two different needs-based professional development surveys that were designed to gather individual teacher input about their technology learning needs and which were correlated to formulate a hypothesis on teacher attitudes and current practices. Relevant organizational data was collected within the School Department. This study utilized a descriptive, quantitative method employing a non-experimental design that studied the phenomena of attitude toward change. The educational research was conducted for the purpose
Analysis of wet & dry weather bacterial concentrations within Kranji & Marina Catchments, Singapore

The Singaporean government's Public Utilities Board aims to open Kranji and Marina Reservoirs to the public for recreational use. Thus, the water bodies have to be safe from fecal contamination in order to protect the people's health during water-contact activities. Under the Singapore-MIT Alliance for Research and Technology (SMART) program, faculty and students from Nanyang Technological University and MIT have worked together to conduct bacteriological studies at both Kranji and Marina catchments and their reservoirs. Storm water, especially from urban landscapes, contains elevated concentrations of total coliform, . coli, and enterococci bacteria. The goal of this study was to review, classify, and evaluate wetand dryweather bacteria samples dating back to 2005 with a focus on grab-samples collected by Nshimyimana (2010) in 2009 and samples collected during January 2011 field work at Choa Chu Kang Crescent, Bras Basah, and Verde. These bacteriological samples were collected from high density residential (HDR), low density residential, forested, and commercial areas. Evaluation of the relationship between concentration and flow showed a linear increase in bacteria concentrations with flow in storm water from mixed forested and HDR areas, a pattern that is consistent with nonpoint source runoff, while commercial areas exhibited peak concentrations during low and high, but not intermediate, flows indicating contributions from both nonpoint and point sources. Likely point sources are sanitary sewer leakage due to aging infrastructure in the commercial area. All measured concentrations exceeded Singapore and USEPA's recommended bacterial levels for recreational water. Hence, more wet-weather sampling is recommended in order to collect data on bacterial concentrations so that more robust statistical analyses can be performed in future studies. The elevated bacterial concentrations during wet weather from this study indicate that extra precaution should be taken to manage discharge of storm water into receiving waters before they are made accessible to the public.

Design, Construction, and Testing of a Hysteresis Controlled Inverter for Paralleling

Abstract : The U. S. Navy is pursuing an all electric ship that will require enormous amounts of power for applications such as electric propulsion. Reliability and redundancy in the electronics are imperative, since failure of a critical system could leave a ship stranded and vulnerable. A parallel inverter drive topology has been proposed to provide reliability and redundancy through load sharing. The parallel architecture enables some functionality in the event that one of the inverters fails. This thesis explores paralleling current-mode inverters of different power levels and fidelities. A 50-kVA, three-phase hysteresis controlled inverter is designed built and tested at low power. The inverter is then tested in parallel with a low frequency, bulk inverter to demonstrate current sharing capability.
