Implementation of Knowledge-Based Expert System Using Probabilistic Network Models

The latest development in machine learning techniques has enabled the development of intelligent tools which can identify anomalies in the system in real time. These intelligent tools become expert systems when they combine the algorithmic result of root cause analysis with the domain knowledge. Truth maintenance, fuzzy logic, ontology classification are just a few out of many techniques used in building these systems. Logic is embedded in the code in most of the traditional computer program, which makes it difficult for domain experts to retrieve the underlying rule set and make any changes. These system bridge the gap by making information explicit rather than implicit. In this paper, we present a new approach for developing an expert system using decision tree analysis with probabilistic network models such as Bayes-network. The proposed model facilitate the process of correlation between belief probability with the unseen data by use of logical flowcharting, loopy belief propagation algorithm, and decision trees analysis. The performance of the model will be measured by evaluation and cross validation techniques

Maximizing ROMI of DMOs: Enabled Through Tourism Investment Framework and Agile Marketing

As most Destination Marketing Organizations (DMOs) are faced with stiffening competition and depleting resources, it requires an agile and reinstituted approach towards the allocation and usage of marketing resources. This paper explores an always-on approach towards destination marketing strategy formulation and execution, leveraging data created through digitalization in the tourism ecosystem. In terms of strategy formulation, the conceptual framework brings together the potential of source markets, the destination’s ability to win, along with the available resources and targets, to dynamically allocate resources to theoretically maximize return on marketing investment (ROMI). For implementation, data-streams are leveraged to allocate marketing budgets to appropriate channels, thereby maximizing the ROMI. The framework is delivered through a data-driven, dynamic model for resource allocation. The model leverages meta-analyses on existing data streams and transactional information created through digitalization in tourism (i.e., internet-of-things or smart tourism), thereby minimizing the costs related to incremental quantitative or qualitative research

Mutual Coupling Reduction in Microstrip Patch Antenna Array by simple I-Shaped DGS using Full Wave Electromagnetic Simulator

When a number of antennas are placed in an array formation, the mutual coupling between the array elements becomes a critical issue. The Microstrip Patch Antennas are useful in sending the onboard parameters to the ground, under different operating conditions. The main aim is to maintain the mutual coupling suppressing structure to the simplest form, while providing a great amount of reduction in the mutual coupling of patch antennas. The idea is to use a Defected Ground Structure (DGS), placed at the bottom of the substrate. It greatly reduces the mutual coupling between the antenna elements, thereby enhancing the antenna performance. The introduction of DGS does not affect other characteristics of the antenna array. The DGS and the normal patch antenna is simulated using CST (Computer Simulation Technology) antenna simulation software. Once an antenna design is finalized, their operational characteristics remains unchanged during the use. DOI: 10.17762/ijritcc2321-8169.150519

Public libraries in Varanasi (Uttar Pradesh), India: an explorative study

The main purpose of this paper is to explore the current status of public libraries of Varanasi. A structured questionnaire was designed and personally distributed to 100 respondents over a period of seven months for the study. Responses present a dismal outlook of the libraries. Financial deficit and lack of computers, infrastructure and staff have stagnated the development of these libraries. These libraries continue to stand the same way as they stood 60 years before

Hand Gesture Recognition using Python

The goal for the project was to develop a new type of Human Computer Interaction system that subdues the problems that users have been facing with the current system. The project is implemented on a Linux system but could be implemented on a windows system by downloading some modules for python. The algorithm applied is resistant to change in background image as it is not based on background image subtraction and is not programmed for a specific hand type; the algorithm used can process different hand types, recognizes no of fingers, and can carry out tasks as per requirement. As it is stated within this paper, the main goals were reached. The application is capable of the gesture recognition in real-time. There are some limitations, which we still have to be overcome in future

Speed Controls the Amplitude and Timing of the Hippocampal Gamma Rhythm

Cortical and hippocampal gamma oscillations have been implicated in many behavioral tasks. The hippocampus is required for spatial navigation where animals run at varying speeds. Hence we tested the hypothesis that the gamma rhythm could encode the running speed of mice. We found that the amplitude of slow (20–45 Hz) and fast (45–120 Hz) gamma rhythms in the hippocampal local field potential (LFP) increased with running speed. The speed-dependence of gamma amplitude was restricted to a narrow range of theta phases where gamma amplitude was maximal, called the preferred theta phase of gamma. The preferred phase of slow gamma precessed to lower values with increasing running speed. While maximal fast and slow gamma occurred at coincident phases of theta at low speeds, they became progressively more theta-phase separated with increasing speed. These results demonstrate a novel influence of speed on the amplitude and timing of the hippocampal gamma rhythm which could contribute to learning of temporal sequences and navigation

Noisy galvanic vestibular stimulation promotes GABA release in the substantia nigra and improves locomotion in hemiparkinsonian rats

Dopamine related disorders usually respond to dopaminergic drugs, but not all symptoms are equally responsive. In Parkinson’s disease (PD) in particular, axial symptoms resulting in impaired gait and postural control are difficult to treat. Stochastic vestibular stimulation (SVS) has been put forward as a method to improve CNS function in dopamine related disorders, but the mechanisms of action are not well understood. This thesis aimed to investigate the effects of SVS on neuronal brain activity and to evaluate the possible enhancing effect of SVS on motor control in PD and on cognitive functions and motor learning in Attention deficit hyperactivity disorder (ADHD). Behavioural tests were conducted in the 6-OHDA rat model of PD using the accelerating Rotarod and the Montoya skilled reach test to evaluate the effect of SVS on motor control. The effect of SVS on brain activity was assessed using in vivo microdialysis and immunohistochemistry. We evaluated the effect of SVS on postural control and Parkinsonism in patients with PD and the effect of SVS on cognitive function in people with ADHD. The behavioural animal studies indicate that SVS may have an enhancing effect on locomotion, but not skilled forepaw function. SVS increased GABA transmission in the ipsilesional substantia nigra (SN) and may have a rebalancing effect on dysfunctional brain activity. SVS increased c-Fos activity more than levodopa and saline in the vestibular nucleus of all animals. c-Fos expression was also higher in this region in the 6-OHDA lesioned than in shamlesioned animals, supporting the theory that SVS may have larger effects in the dopamine depleted brain. SVS increased c-Fos expression in the habenula nucleus substantially more than levodopa did. Furthermore, SVS and levodopa had similar effects on many brain regions, including the striatum, where saline had no effect. The clinical studies revealed improvement of postural control in PD during SVS. There was a trend towards reduced Parkinsonism during SVS when off levodopa. No substantial effects were found on cognitive performance in ADHD. In PD, SVS may improve motor control by inhibiting the overactive SN, possibly through a non-dopaminergic modulatory pathway involving increased neurotransmission in the habenula nucleus. SVS could be trialled in larger studies to evaluate long-term effects on treatment resistant axial symptoms associated with PD

Finite Element Analysis of Helical Gear

The gears mostly fail due tobending and surface stresses on gear tooth. This paper investigates the characteristics of a pair of helical gear system, bending stresses, in the gear mesh. Gear plays a major role in power transmission in mechanical systems. In this paperfinite element analysis has been performed to evaluate bending stresses in the root of gear tooth having involute profile. Parametric studies have been conducted by considering different helical angle and two different materials. In analytical method, the bending equation by AGMA (American gear manufacturers association) is used to calculate bending stress on gear.It is important to develop appropriate models of contact element and to get equivalent result using numerical approach and compare the result with standard AGMA stress. The variation of the bending stresses at the root of the teeth of helical gear with respect to different helix angle has been analyzed
